Description

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

(B) Prior Art Conventionally, the present inventor has provided an intermittent extrusion device for raw materials for paste products, as shown in FIG.
Disposed horizontally on the outlet b in this hopper a,
An extrusion roller c, which has an extrusion part A and a partition part B on its circumferential surface, is arranged opposite to the extrusion roller c on the raw material introduction side, and moves back and forth through a window hole d of a hopper a to determine the amount of raw material to be introduced. An adjustable setting member e is fitted into the window hole f of the hopper a so as to be located above the outlet b of the hopper a, and is pressed against the extrusion roller c by a spring g, so that the raw material is removed from the extrusion roller c. It is equipped with a scraping member h for scraping off,
Since a certain amount of raw material can be extruded intermittently from the outlet, 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 to avoid applying excessive pressure to the raw material. Therefore, the raw materials will not be over-kneaded or the contaminants will not lose their shape, making it possible to mold products with good quality.

In addition, if the distance between the extrusion roller and the extrusion roller is determined by the setting member, and the raw material is scraped off from the extrusion roller at the rear side of the exit, the amount of raw material fed out will be accurately determined and there will be no discrepancy, so the product will be uniform. Moreover, by moving the setting member back and forth and adjusting the distance between it and the extrusion roller, the extrusion amount can be freely increased or decreased, and the size and weight of the product can be arbitrarily changed. It is effective.

(c) Problems to be solved by the invention In the conventional device described above, a raw material introduction amount setting member and a raw material scraping member are fitted into a window hole provided in a hopper so as to be able to move forward and backward. It is very difficult to move a long member over the entire width of the machine easily and without leaking raw material, and the processing cost is high.In addition, this window hole sliding type has a large resistance.
This tendency becomes even more pronounced when the raw material enters between the window hole and the member, so when the member is pressed by a spring and is moved in contact with the extrusion roller, not only does this operation become uncertain, but also the There was also the problem that adjustments could not be made smoothly.

Therefore, the present invention provides an intermittent extrusion system for raw material pastes that solves the above-mentioned conventional problems by having a structure in which a raw material introduction amount setting member and a raw material scraping member are rotated around an axis. It provides equipment.

(d) Means for Solving the Problems The intermittent extrusion device for raw materials for pastes according to the present invention includes a hopper into which the raw materials are fed, and an extrusion section horizontally disposed above the outlet in the hopper. an extrusion roller provided with and a partition portion; an adjustable setting member disposed oppositely on the raw material introduction side to the extrusion roller and for determining the amount of raw material introduced by rotational movement about an axis; A scraping member is rotatably supported above the outlet and pressed against the extrusion roller by an elastic device to scrape off the raw material from the roller.

(E) Function In the device of the present invention based on the above-mentioned means, when the raw material is introduced into the hopper, the raw material is sent to the position of the introduction amount setting member by the extrusion roller, and in the extrusion section, there is a Since there is a gap, the raw material is sent to the outlet through the gap, and is scraped off from the extrusion roller by a scraping member on the rear side, and the entire amount that has passed through the gap is extruded to the outlet. The feeding stops and so-called intermittent extrusion is performed.

There is.

Reference numeral 12 denotes a scraping member for scraping off the raw material from the extrusion roller 5, and a shaft 13 whose one end is horizontally suspended in the hopper 1.
A lever 14 is fixed to the shaft 13 using a plate whose other end is in contact with the lower circumferential surface of the extrusion roller 5. A spring 15 is provided in close contact with the roller 5 to completely scrape off the raw material adhering to the roller 5.

Reference numeral 16 denotes a raw material adjustment screw which is screwed into the outlet 2 of the hopper 1 as necessary, and adjusts the amount of protrusion toward the outlet 2 by moving forward and backward, thereby finely adjusting the amount of raw material extruded from the outlet 2.

A is a fishball forming machine installed below the outlet 2 of the hopper 1 described above, which includes a concave forming member 17 that presses the center of the raw material extruded from the outlet 2 to form a concave, and a concave forming member 17 that presses the center of the raw material extruded from the outlet 2 to form a concave, and a concave forming member 17 that presses the center of the raw material extruded from the outlet 2 to form a concave part, and It is provided with a semicircular cutting blade 18 for cutting into a spherical shape at the edge of the opening 2, and operating means 19 and 20 for operating both members 17 and 18 in synchronization with extrusion of the raw material.

Reference numeral 21 denotes a small hole for water supply provided in the center of the above-mentioned concave forming member 17, which is connected to a water pipe 22 through a flexible tube 23, and wets the pressing surface with water when pressing the raw material with the forming member 17.

B is a rotary molding machine, which forms molding recesses 25 at predetermined intervals on the circumferential surface of a rotor 24, as shown in FIG.
It houses an extrusion piece 26 that moves up and down under the action of gravity, and rotates the rotor 24 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
The power is transmitted to the intermediate chain wheel 29 by the intermediate chain wheel 29.
from the chain 30 to the extrusion roller 5, and from the synchronized chain 31 to the operating means 19.
Rotation is transmitted from the to the operating means 20 by gears 32 and 33.

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

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. 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 12 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. 2 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 aforementioned setting member 7 and the extrusion portion A of the extrusion roller 5, so if you want to change this, you can set it using the screw-type stopper 11. If the member 7 is fed out against the extrusion roller 5 and the gap is narrowed to reduce the amount of extrusion, or the setting member 7 is pulled down and the gap is widened to increase the amount of extrusion, the molding machine can mold the member 7. The size and weight of the product can be adjusted as desired.

Therefore, the drawing number 1 is located below the outlet 2 of the hopper 1.
A fishball forming machine A as shown in the figure is installed,
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, the concave forming member 17 is pressed against the center of the raw material and escapes after making a concave in the raw material. Semi-circular cutting blade 1
8 rotates inside the outlet 2 from one side to the other, cutting the raw material into a spherical shape and escaping, the next raw material is pushed out, and the forming member 17 makes a recess and the semicircular cutting blade 18 cuts the raw material. Therefore, the molding machine A efficiently and automatically manufactures products without degrading quality due to over-kneading of raw materials or deformation of contaminants by intermittent supply of raw materials.

Further, if a rotary molding machine B as shown in FIG. 3 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 25 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.

Note that this device is used as an extrusion roller 5 as shown in drawing No. 5.
As shown in the figure, an oval type with two extrusion parts A and two partition parts B can be used, or a triangular type with three extrusion parts A and three partition parts B as shown in Fig. 6 can be used. In these cases, the same effect as described above can be achieved by reducing the rotational speed to 1/2 or 1/3 compared to the eccentric ring type described above and adjusting the timing with the raw material extrusion.

(G) Effects of the Invention The device 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.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 during non-molding to avoid applying excessive pressure to the raw material. Therefore, the raw materials will not be over-kneaded or the mixed articles will not lose their shape, making it possible to mold products with good quality.

Since the extrusion amount setting member is adjustable and opposite to the extrusion roller, and the raw material scraping member is pressed against the extrusion roller, the setting member determines the distance between the extrusion roller and the raw material from the roller at the rear side of the exit. If scraping is performed, the amount of raw material delivered will be accurately determined and there will be no discrepancy. Therefore, it is effective in making the product uniform, and by moving the setting member back and forth and adjusting the distance between it and the extrusion roller, the amount of extrusion can be freely increased or decreased, and the size and weight of the product can be changed arbitrarily. let

The material introduction amount setting member and the raw material scraping member are rotated around the shaft to adjust the distance between them and the extrusion roller and to press the roller against the extrusion roller.Just by drilling a shaft hole in the hopper, Processing costs are low because it can be easily installed without causing material leakage, and if a lever is attached to the shaft outside the hopper, the lever can be used to adjust the distance or apply pressure to the spring appropriately. The metering and scraping of raw materials can be carried out reliably.

It has the following unique effects.
