Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a rotary cylindrical processing device, and more specifically, the present invention relates to a rotary cylindrical processing device, and more specifically, it is used to process articles to be cooled or heated, such as synthetic resins, crushed fish or meat, in the form of sheets, etc. It relates to a device for processing by supplying the liquid in an appropriate form and pressing it onto the surface of a rotating cylindrical body that is being cooled or heated.

(Prior Art) Conventionally, this type of device has been used as a cooling device that is part of a crushing device in the manufacturing process of thermoplastic, thermosetting synthetic resins, etc. −
It is disclosed in Japanese Patent No. 225882. The conventional rotating cylindrical processing apparatus described in the publication includes a rotatably supported cylindrical body 1 and a cooling or heating mechanism for cooling or heating this cylindrical body 1, as shown in FIG. 2 and
A supply section 3 that supplies a workpiece to the surface of the cylindrical body 1; and a brasha, which is arranged adjacent to the supply section 3 and presses and rolls the workpiece 4 discharged from the supply section against the surface of the cylindrical body 1. The roll 5 is stretched along the outer periphery of the cylindrical body 1, and the cylindrical body 1
It mainly consisted of an endless belt 6 that transports the object 4 supplied to the surface of the cylindrical body 1 while keeping it in close contact with the cylindrical body 1.

(Problem R to be solved by the invention) In the conventional rotating cylindrical processing apparatus described above, when the workpiece 4 is continuously rolled by the pressure roll 5, the rolled workpiece 4 sticks to the pressure roll 5. In some cases, the cylindrical body 1 did not come off the surface of the cylindrical body 1 and was lifted up from the surface of the cylindrical body 1 and wound around the pressure roll 5. Therefore, a scraper 7 is installed on the rolling outlet side, the tip of which is close enough to slide on the circumferential surface of the pressure roll 5, and is used to peel off the workpiece 4 wrapped around the pressure roll 5 as shown in FIG. It was then returned to the circumferential surface of the cylindrical body 1 by its own weight.

However, when the object 4 to be treated is made of resin, even if it is peeled off from the circumferential surface of the pressure roll 5 by the scraper 7, it may not return to the circumferential surface of the cylindrical body 1 due to its own weight. The processed material 4 sometimes wound around the scraper 7 or went beyond the scraper 7 in a direction away from the cylindrical body 1. If such a situation occurs, it is necessary to stop the rotary cylindrical processing device and restore the workpiece 4 to its normal state. Therefore, the conventional rotary cylindrical processing device W has some resistance to its operation. There was a lack of reliability.

The purpose of the present invention was to solve such conventional problems, and when a workpiece wrapped around a pressure roll is peeled off with a scraper, the peeled workpiece is automatically scraped onto the surface of a cylindrical body. An object of the present invention is to provide a rotary cylindrical processing device that improves the reliability of continuous operation.

(Means for Solving the Problems) A rotating cylindrical processing apparatus of the present invention includes a rotatably supported cylindrical body, a cooling or heating mechanism for cooling or heating the cylindrical body, and a surface of the cylindrical body. a supply section for supplying the workpiece to the cylinder; and a brake disposed adjacent to the supply section and on the rotational direction side of the cylindrical body, which presses and rolls the workpiece coming out of the supply unit against the surface of the cylinder. a non-yarn roll, an endless belt stretched along the outer periphery of the cylindrical body in order to transfer the workpiece rolled by the blurred roll while being in close contact with the cylindrical body, and a rolling outlet side. a scraper installed near the middle roll of the pressure roll, the tip of which is close to the circumferential surface of the pressure roll;
A guide plate forming a guide surface continuous with the tip surface of the scraper, the guide surface of the guide plate returning the rolled workpiece that is about to leave the cylindrical body to the circumferential surface of the cylindrical body. It is characterized by being curved.

(Function) According to the rotating cylindrical processing device of the present invention, the workpiece supplied from the supply section to the surface of the cylindrical body enters the gap between the pressure roll and the cylindrical body, is rolled to a constant thickness, and then is rolled to a constant thickness. The object to be processed is transported through a predetermined rotation range while being in close contact with the surface of the cylindrical body by an endless belt, during which time the object to be processed is sufficiently cooled or heated.

By the way, during rolling, the workpiece that is sandwiched between the pressure roll and the cylindrical body sometimes tries to wrap around the pressure roll while remaining stuck to the surface of the pressure roll.
In that case, the scraper peels off the workpiece from the pressure roll, and the peeled workpiece comes into contact with the surface of the guide plate and is guided back to the surface of the cylindrical body while sliding on the surface, and is returned to the surface of the cylinder by the endless belt. Pressed against the cylindrical surface.

(Example) Hereinafter, the rotary cylindrical processing apparatus of the present invention will be described in more detail with reference to the embodiment shown in the accompanying drawings.

FIG. 1 is a configuration explanatory diagram partially showing a pressure roll and components provided around it in a rotary cylindrical processing apparatus according to an embodiment of the present invention, and other parts are shown in FIG. It is the same as the conventional processing equipment.

In the rotary cylindrical processing apparatus of this embodiment, as is clear from FIG. 1, a scraper 10 is installed near the pressure roll 5 on the rolling outlet side.

This scraper 10 is equipped with a support stand 11 firmly fixed to a frame such as a casing of the processing equipment, and a scraper main body 12 made of Teflon resin is mounted on the upper part of this support stand 11, and the tip thereof is attached to a brency roll. It is fixed with a bolt or the like at a position close enough to slide on the circumferential surface of 5.

The end surfaces 11a, 12a of the support base 11 and the scraper body 12 are continuous surfaces substantially parallel to the surface of the cylindrical body 1. End surface 1 at the tip of the support stand 11
1a is Teflon coated or mirror finished. The reason why the scraper body 12 is made of Teflon resin and the end surface 11a of the support base 11 is coated with Teflon or mirror-finished is that even when the object to be treated is a highly adhesive resin, the scraper body 12 is made of Teflon resin.
2 and the continuous end surface 12a of the support base 11.

This is to allow it to escape smoothly without adhering to 11a. In this case, the reason why the entire scraper body 12 is made of Teflon resin is that a relatively large frictional force acts on the end surface 12a of the scraper body 12 that first peels off the workpiece 4 adhering to the surface of the pressure roll 5. This is because a Teflon coating with a film thickness of several microns cannot cope with this problem because of wear.

A guide plate 13 is attached to a support stand 11 in the scraper 10. As shown in FIG. 1, this guide plate 13 has a concave surface 13a facing the surface of the cylindrical body 1, and one end 13b of the guide plate 13 is connected to each end surface 12a of the scraper body 12 of the scraper 10 and the support base 11.

The concave surface 13a of the guide plate 13 is fixed to the lower end of the end surface 11a of the support base 11 by welding or the like so that the concave surface 13a of the guide plate 13 is continuous with the continuous smooth flank formed by the guide plate 11a. One end of a fixing plate 14 is fixed to the back surface of the guide plate 13 in the vicinity of the intermediate portion in the length direction, and the other end is fixed to a suitable position on the support base 11. Thereby, the guide plate 13 is firmly installed at a predetermined position on the rolling exit side. Place the other end 13c of the guide plate 13 close to the surface of the cylindrical body 1! It is decided. As a result, the direction along the concave surface 13a of the guide plate 13 is directed toward the surface of the cylindrical body 1.

At this time, the distance l between the other end 13b of the guide plate 13 and the surface of the cylindrical body 1 is set to a size that corresponds to the maximum thickness of the workpiece 4 to be rolled and allows the workpiece 4 to pass therethrough.

As is clear from FIG. 1, the concave surface 13a of the guide plate 13 acts as a guide surface for guiding the workpiece 4 peeled off from the pressure roll 5 by the scraper 10 back to the surface of the cylindrical body 1. Since the object to be treated 4 comes into sliding contact with the concave surface 13a, it is preferable that the concave surface 13a is coated with Teflon or mirror-finished so that the object to be treated 4 does not adhere thereto.

According to the rotary cylindrical processing apparatus according to the embodiment with the above-described configuration, when the workpiece 4 adheres to the pressure roll 5 and lifts up from the surface of the cylindrical body 1 during rolling of the workpiece 4, the scraper 10 This is peeled off from the pressure roll 5, but since the workpiece 4 is continuously rolled and sent to the rolling outlet side, the pre-roll 5
The peeled workpiece 4 tries to move outward in the radial direction of the cylindrical body I through the underside of the scraper 10 as if being pushed out, but it comes into contact with the concave surface 13a of the guide plate 13, that is, the guide surface. It is blocked, and is returned to the surface of the cylindrical body 1 by sliding on the concave surface 13a, thereby being inserted into the endless belt 6. In this way, the workpiece 4 peeled off from the blister roll 5 is guided by the guide plate 13 and automatically and quickly returned to the cylindrical body surface, allowing continuous processing without stopping the rotating cylindrical processing device. Able to drive safely.

(Effects of the Invention) As explained above, the rotating cylindrical processing device of the present invention includes a guide plate that forms a guide surface continuous with the tip surface of the scraper, and the guide surface is separated from the cylindrical body. Since it is curved so that the rolled workpiece is returned to the circumferential surface of the cylindrical body, even if the workpiece adheres to the pressure roll, it is automatically peeled off and returned to the cylinder. The reliability of continuous operation can be improved without stopping the equipment.
