Description

Technical Field

[0001] The present invention belongs to the field of fish ball processing, and specifically relates to an automatic forming device for facilitating the adjustment of fish ball size and its processing method. Background Art

[0002] The processing of fish balls mainly involves the automated process from fish mince to formed fish balls. Using a fish ball forming machine, the fish mince is put into the hopper, fed through a spiral feeder, and enters the forming die. Depending on the size of the mold carrier of the die used, fish balls of different sizes can be processed. At the outlet of the die, through the set cutting knife holder, it cuts back and forth to cut the independent fish balls. After cutting, the cut fish balls fall into the steaming pool for heating and forming. With automated operation, the forming speed is fast, the output is significantly increased, it is suitable for large-scale production, the labor cost is reduced. The size of the formed fish balls mainly depends on the die controlling the size of the fish balls out of the mold, ensuring product consistency, improving the aesthetic degree and standardization level.

[0003] In order to ensure the consistency of the size of the formed fish balls, the die is usually fixedly installed above the cutting knife holder. When disassembling and assembling the die, it is necessary to open the side covers on both sides of the cutting knife holder, then remove the cutting knife holder, and then remove the die holder above, take out the die in the die holder. After changing to a die of other sizes, the die holder and the knife holder are installed in turn. If the tool is not installed in place, it may cause the fish balls to be misaligned and the fish balls cannot be formed. Moreover, frequently disassembling and assembling the knife holder will also cause wear of the knife holder parts, resulting in equipment vibration, inaccurate cutting frequency parameters of the blade, and the need to recalibrate the lining, reducing the qualified rate of the finished product.

[0004] In summary, the present invention provides an automatic forming device for facilitating the adjustment of fish ball size and its processing method to solve the above problems. Summary of the Invention

[0029] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0030] Example 1

[0031] As Figures 2 - 5 shown, the present invention provides an automatic forming device for facilitating the adjustment of the size of fish balls, which includes a forming machine 1. A feeding hopper 2 is installed on the forming machine 1 through a hopper fixing seat 18. The discharge port of the feeding hopper 2 is connected to a feeding pipeline 3. The output end of the feeding pipeline 3 is connected to a die seat 10. A cutting knife seat 4 is installed on the forming machine 1. The die outlet of the die seat 10 is aligned with the cutting knife seat 4. The bottom of the feeding pipeline 3 is connected to the die seat 10 through a mounting kit one 5. The mounting kit one 5 includes a feeding connection pipe 501, a die positioning sleeve 502 and a ball sliding sleeve one 506. The feeding connection pipe 501 is connected to the die positioning sleeve 502. The ball sliding sleeve one 506 is slidably sleeved on the surface of the die positioning sleeve 502. A plurality of die locking balls 504 are slidably arranged on the surface of the die positioning sleeve 502. A locking groove one 11 is formed on the surface of the die seat 10. The surface of the die locking ball 504 is in contact with the inner wall of the locking groove one 11. A ball card slot 507 is formed in the ball sliding sleeve one 506. The die locking ball 504 is in contact with the ball card slot 507. The middle part of the die seat 10 is a die inner groove, and a die 9 is arranged in the die inner groove. A spiral feeder 17 is installed on the forming machine 1. The conveying auger on the spiral feeder penetrates through the feeding hopper 2 and extends into the feeding pipeline 3.

[0032] As an implementation manner of the present invention, a plurality of ball through holes arranged in an annular array are formed on the die positioning sleeve 502. The die locking balls 504 are respectively movably arranged in the ball through holes. The outer walls of the die locking balls 504 respectively protrude from the two end orifices of the ball through holes and are in contact with the ball card slot 507 and the locking groove one 11.

[0033] As Figure 3 , the die locking ball 504 is inserted into the locking groove one 11. The opposite surface of the die locking ball 504 away from the locking groove one 11 is in contact with the ball card slot 507 and is limited by the ball card slot 507 and cannot move left and right. Thus, the die positioning sleeve 502 can be stably sleeved on the surface of the die seat 10 and cannot move up and down any more. Furthermore, the connection and installation work between the feeding pipeline and the die seat 10 is completed.

[0034] As an embodiment of the present invention, the mold positioning sleeve 502 is of an annular structure, and the ball card slots 507 are arranged along the inner annular wall. The ball card slots 507 include an inclined surface annular wall and a vertical surface annular wall. The inclined surface annular wall is arranged above the vertical surface annular wall. A spring inner groove 508 is also formed on the inner annular wall of the mold positioning sleeve 502. A sleeve limiting ring 503 is installed on the outer wall of the mold positioning sleeve 502, and the sleeve limiting ring 503 is covered in the spring inner groove 508. A first reset spring 505 is wound around the surface of the mold positioning sleeve 502, and both ends of the first reset spring 505 are respectively arranged between the spring inner groove 508 and the sleeve limiting ring 503.

[0035] As Figures 2 - 3 , when the mold is installed, the mold locking ball 504 contacts and engages with the first locking groove 11. At this time, the ball card slot 507 in the mold positioning sleeve 502 also contacts the mold locking ball 504. The inclined surface annular wall that contacts the mold locking ball 504, and the inclined inner wall of the inclined surface annular wall abuts against the surface of the mold locking ball 504 to prevent the mold locking ball 504 from moving out of the first locking groove 11, thereby fixedly connecting the mold base 10.

[0036] When the mold is removed, the mold positioning sleeve 502 is moved upward, so that the vertical surface annular wall approaches the mold locking ball 504, increasing the moving space of the mold locking ball 504. Then, the mold positioning sleeve 502 is continuously moved upward, driving the material conveying connecting pipe 501 to slide on the surface of the material conveying pipe 3. When the other end of the mold locking ball 504 is not limited, it can be extruded by the first locking groove 11. Then, the mold locking ball 504 moves in the ball through hole, and the mold base 10 is separated from the first installation kit 5, exposing the mold 9, and the mold 9 is taken out.

[0037] After replacing the mold 9 with other sizes, the material conveying connecting pipe 501 can be moved downward again. After the mold positioning sleeve 502 is aligned with the mold base 10, the mold positioning sleeve 502 can be released. Under the action of the first reset spring 505, the inclined surface annular wall pushes the mold locking ball 504 to engage into the first locking groove 11 again to complete the installation.

[0038] As Figure 4 , the first reset spring 505 provides a tension support between the mold positioning sleeve 502 and the first ball sliding sleeve 506. The first reset spring 505 presses the first ball sliding sleeve 506, so that when the first ball sliding sleeve 506 is not subjected to external force, the inclined surface annular wall is always close to one side of the mold locking ball 504 to lock the mold locking ball 504.

[0039] As an embodiment of the present invention, a gasket groove is provided at the mold opening at the top of the mold base 10, and a first gasket 8 is arranged in the gasket groove. The side surface of the first gasket 8 opposite to the mold base 10 contacts the inner wall of the mold positioning sleeve 502.

[0040] As Figure 4 , during installation, one end of the mold positioning sleeve 502 is sleeved on the surface of the mold base 10, and then the contact part of the two is sealed by the first washer 8.

[0041] As an implementation manner of the present invention, sealing rings 7 are respectively arranged at both ends of the feeding pipeline 3. The feeding connecting pipe 501 is movably sleeved on the surface of the feeding pipeline 3. The inner wall of the feeding connecting pipe 501 is in contact with the sealing ring 7. One side of the feeding connecting pipe 501 is fixed to one side of the molding machine 1 through the first snap-in plug 12. A first snap-in seat 19 is installed on one side of the molding machine 1, and the first snap-in plug 12 is movably inserted into the surface of the first snap-in seat 19.

[0042] The feeding connecting pipe 501 can move up and down on the surface of the feeding pipeline 3 to provide an operating space for disassembling and assembling the mold.

[0043] As Figure 4 , the first snap-in plug 12 is inserted into the surface of the first snap-in seat 19 from top to bottom, and the two are snap-connected to prevent the first installation kit 5 from shaking during operation.

[0044] A processing method of an automatic forming device for facilitating the adjustment of the size of fish balls. The processed surimi is put into the interior through the feeding hopper of the feeding hopper 2. The screw feeder 17 is started, and the feeding auger uniformly inputs the surimi to the bottom of the feeding pipeline 3 and enters the mold 9. Then, the cutting knife seat 4 uniformly cuts the surimi extruded through the mold forming and falls into the steaming pool for steaming and forming.
