Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for performing intermittent extrusion of raw materials in a processing plant for fish paste products.

Conventionally, an extrusion device that charges raw material for a paste into a hopper and extrudes it in predetermined amounts from an outlet is well known, for example, from Japanese Utility Model Publication No. 16951/1983.

This product is a dough product in which a pressing roll with a pressing plate inserted into it so that it can move in and out is placed opposite to a forming roll with a mold hole in which the pressing die can move in and out, and the raw material is filled into the mold hole. In the molding machine, the support tube of the pushing roll is rotatably fitted into the hopper, an insertion plate lifting piece is provided at the inner end of the support tube, and the support tube is further provided with a rotating means. It is. Therefore, by moving the pushing plate upper piece to the filling passage side so that the pushing plate can force feed the raw material over a long distance along the section wall, a large pressure can be applied to the raw material and the filling pressure can be increased. Then, by moving the pushing plate upper piece in the opposite direction and immersing the pushing plate into the pushing roll on the starting end side of the section wall, shortening the distance that the pushing plate forces the raw material along the section wall, Since the force applied to the raw material can be reduced and the filling pressure can be lowered, if the filling pressure is adjusted appropriately depending on the properties of the raw material and the presence or absence of contaminants, over-kneading of the raw material due to excessive filling pressure can be avoided. In addition, it is possible to prevent contaminants from deforming and obtain a high-quality paste product.

However, this extrusion device does not have the function of adjusting the amount of raw material extruded and the function of intermittent extrusion,
The amount of extruded raw material is always constant, so the size and weight of the product cannot be changed, and since the material is pressurized during the molding process, there is no need to over-knead the raw material or lose the shape of contaminants. However, there were some problems that could arise.

The present invention was made in accordance with this current situation, and includes an extrusion roller having an extrusion section and a partition section, and a setting member that can arbitrarily set the amount of raw material introduced into this roller.
By providing a scraping member for scraping off the raw material from the extrusion roller, it is possible to control the amount of raw material extruded and to feed the raw material intermittently, thereby solving the above-mentioned conventional problems.

Next, an example of implementation of the apparatus related to the present invention will be explained based on the drawings.

It is designed so that it will be done.

Reference numeral 15 denotes a scraping member for scraping off the adhering raw material from the extrusion roller 5, which is movably fitted into a sliding guide 16 having the same width as the through hole 8 provided in the wall surface of the hopper 1 on the opposite side from the through hole 8. and a shaft rod 17 protrudingly provided on the outside of this scraping member 15 to be inserted into a hole 16' provided on the outside of the sliding guide 16,

Numeral 19 is a raw material adjusting screw screwed into the outlet 2 of the hopper 1 described above, and the amount of raw material extruded from the outlet 2 is finely adjusted by adjusting the amount of protrusion toward the outlet 2 by moving forward and backward.

A is a fishball forming machine installed below the outlet 2 of the hopper 1, which includes a concave forming member 20 that presses the center of the raw material extruded from the outlet 2 to form a concave, and a concave forming member 20 that presses the center of the raw material extruded from the outlet 2 to form a concave, and The apparatus includes a cutting member 21 for cutting in an arc shape at the edge of the mouth of the second part, and operating means 22 and 23 for operating the two members 20 and 21 in synchronization with the extrusion of the raw material.

B is a rotary molding machine that forms molding recesses 25 at predetermined intervals on the circumferential surface of a rotor 24;
Extrusion pieces 26 that move up and down under the action of gravity are housed in the bottoms of these recesses 25, and the rotor 24 is rotated in synchronization with the extrusion of the raw material from the outlet 2.

27 is a motor that drives each part, and a chain 28

Next, the operation of the present invention will be explained based on the above embodiments.

When a raw material mainly consisting of fish meat paste is fed into the hopper 1 through the opening at the top, the raw material passes between the rollers 3, 3 and flows downward because the feed rollers 3, 3 are rotating inwardly. When the raw material is sent onto the extrusion roller 5 of It is sent to the outlet 2 through the gap, and is scraped off from the extrusion roller 5 by the scraping member 15 on the rear side.
The entire amount passing through the gap is pushed out to the outlet 2.

The extrusion roller 5 that has finished extruding the raw material in this way
Next, as shown in FIG. 4 of the drawings, the partition part b is brought into contact with the setting member 7, and during this period, the introduction of the raw material is continued to be prevented, and the extrusion part a corresponds to and is connected to the setting member 7. Since the operation of feeding the raw material to the outlet 2 is repeated while a gap is formed in between, a fixed amount of the raw material is intermittently delivered from the outlet 2 of the hopper 1.

The amount of raw material extruded in this way is determined by the distance between the setting member 7 and the extrusion part a of the extrusion rotor 5, so if you want to change this,
By using the adjusting screw 9, the setting member 7 is fed out against the extrusion roller 5, and the amount of extrusion can be decreased by increasing the gap, or by pulling down the setting member 7 and widening the gap, increasing the amount of extrusion. , the size and weight of the product molded by the molding machine can be adjusted as desired.

Therefore, the drawing number 1 is located below the outlet 2 of the hopper 1.
Install the tsumare molding machine A as shown in the figure,
If this molding machine A is operated in synchronization with the extrusion of the raw material, when the raw material is extruded from the outlet 2, it is pressed against the central part by the recessed operation member 22, and after making a recess in the raw material, it is moved to the standby position. As a result, the cutting member 21 is engaged with the edge of the outlet 2 by the operation member 23 to cut the raw material in an arc shape, and then opened, the next raw material is pushed out and the forming member 20 makes a recess. Since the raw material is cut by the cutting member 21, the molding machine A efficiently and automatically manufactures products without deterioration in quality due to over-kneading of the raw material or loss of shape due to contaminants by intermittent supply of the raw material.

Further, if a rotary molding machine B as shown in FIG. 6 is installed below the outlet 2 of the hopper 1 and the rotor 24 is operated in synchronization with the extrusion of the raw material, the raw material will be extruded from the outlet 2. When the molding recess in the rotor 24 is filled with the raw material corresponding to the outlet 2, the rotor 24 rotates as filling is completed, and when switching between the filled recess 25 and the empty recess 25, the raw material is filled. Since extrusion is stopped, this rotary molding machine B can efficiently and automatically manufacture products without deterioration in quality due to over-kneading of raw materials or deformation of contaminants.

The extrusion roller 5 of this device may be a circular one having two pressing parts a and two partition parts b as shown in FIG. 3, or a pressing part a as shown in FIG.
In these cases, the rotational speed is reduced to 1/2 or 1/3 compared to the eccentric wheel type described above, and the rotation speed is reduced to If the timing is right, the same effect as described above will occur.

The apparatus according to the present invention rotates an extrusion roller having an extrusion part and a partition part in a hopper,
The extrusion section sends the raw material to the outlet, and the partition section stops the raw material, so a certain amount of raw material can be extruded intermittently from the outlet, so if this extrusion device is combined with a molding machine, , the raw material can be supplied only during molding, and the supply can be stopped when not molding, so as not to apply excessive pressure to the raw material. Therefore, it is possible to prevent the raw materials from being over-kneaded and the mixed articles from losing their shape, making it possible to mold products with good quality.

In addition, this device has an extrusion amount setting member adjustable and opposite to the extrusion roller, and a scraping member for the raw material. If the raw material is scraped off from the roller, the amount of raw material fed out will be accurately determined and there will be no discrepancies, so it is effective for making the product uniform. By adjusting the amount, the extrusion amount can be freely increased or decreased, and the size and weight of the product can be arbitrarily changed. It is highly effective.
