Description

Description: TECHNICAL FIELD The present invention relates to a method for extruding a shaped incense stick material in a uniform length from a plurality of nozzle holes of an extrusion nozzle on a continuous extruder for producing French incense sticks. And equipment.

[Prior Art] For example, for incense sticks for Buddha, a raw material is a bark powder mixed with glue powder and an appropriate fragrance and kneaded with water to form a clay. Extrusion molding step of raw material, tray receiving step of cutting the molded flavoring material obtained in this step on a plate, shredding step of cutting the raw incense received in this tray to an appropriate length, further drying through a raw-growth step, It has been commercialized.

Further, in recent years, each manufacturing process of the above-mentioned French incense has been automatically automated.

In the extrusion molding process described above, an extruder using hydraulic pressure or the like has been conventionally used, and a nozzle portion on the extruder has a plurality of nozzle holes at a front position on a straight line or a parallel straight line at regular intervals. Be worn. Therefore, the plurality of molded incense sticks extruded from the nozzle holes are obtained in a blind shape.

When receiving trays for each of these blind-shaped shaped incense sticks, the lengths on tray trays or drying boards should be the same. Surplus occurs. This surplus was reduced to the inside of the extruder as a separating material by hand, but in the automatic mechanization of the production, the extruder was designed to be capable of continuous operation for reasons of production efficiency and equipment configuration. The structure in which the surplus separating material is directly returned to the continuous extruder has been adopted. As a continuous extruder, a screw type extruder 22 as shown in FIG. 6 has been conventionally used.
The continuous extruder 22 has a shaft 23, one end of which is rotatably supported along the tube axis in a tubular shape, and has a helical screw blade 24 on the circumferential surface of the shaft 23. There is one in which a receiving hopper 26 is provided on the upper rear portion of the tubular shape, and a nozzle portion 28 is provided on the front portion via a conduit portion 27.

[Problems to be Solved by the Invention] In the conventional continuous extruder 22 as described above, the raw material for incense stick X is fed from the receiving hopper 26, and the surplus cutting material C is also fed to the reducing device 71. The transfer conveyors 72 are sequentially transferred into the receiving hopper 26. Incidentally, 72a is a receiving plate.

The raw material for incense stick X and the separating material C thus fed into the continuous extruder 22 are sequentially moved forward along the surface of the screw blade 24, and further fixed by the holder 29 on the end face of the nozzle portion 28. Are extruded from the nozzle holes 30a of the extruding nozzle 30 and molded into the molded incense stick material A '. At this time, the obtained molded incense sticks A ′ ..., As shown in FIG. 6, the nozzle holes 30a formed on the straight line at different intervals have different extrusion amounts, and therefore different. Obtained in length. It is considered that this is because the separating material C is mixed in the raw material X and the density thereof is not constant.

When the molded incense stick materials A '... are extruded from the extruding nozzle 30 at different speeds, the tray receiving operation takes a long time, and the extruding interval becomes unstable. The amount of the release material C was extremely large, which was a cause of greatly reducing the manufacturing efficiency.

An object of the present invention is to solve the above-mentioned drawbacks of the conventional apparatus, and to provide an extrusion molding method and apparatus capable of stably extruding the molding incense stick material from the extrusion nozzle at a constant length. .

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention has the following configuration for the extrusion molding method for French incense sticks.
