The blanking plate cooperates with the feeding device.

[0012] A water circulation cooling processing method for fish ball production is as follows:

[0013] S1. First, the staff injects the cooked fish balls into the pressure feed bin from both sides of the pressure feed bin. The water outlet of the water circulation component can push the fish balls to the middle of the pressure feed bin. Then, the cylinder drives the pressing plate to descend, and the sliding block will gradually slide down inside the guiding groove. At this time, the fish balls will be covered inside the bottom frame, and the fish balls will be brought by the pressing plate to the bottom of the pressure feed bin. When the sliding block slides from the guiding groove into the rotating groove, the front end of the pressing plate will rest on the top of the mating edge. The cylinder drives the pressing plate to continue descending. Since the front end of the pressing plate is blocked by the mating edge, the other end of the pressing plate will rotate around the smooth rod as the center, and the sliding block will rotate inside the rotating groove. Finally, the pressing plate will be in an inclined state, and the pressing plate will be parallel to the discharge channel. Under the action of its own buoyancy, the fish balls will move into the discharge channel;

[0014] S2. When the fish balls enter the discharge channel, since the discharge channel is inclined as a whole, the fish balls will first be conveyed from the pressure feed bin to the filtering bin. The smaller fish balls will, under the action of their own buoyancy, pass through the filter net and float on the water surface inside the filtering bin, while other fish balls will be conveyed into the transfer bin;

[0015] S3. The fish balls entering the transfer bin will, under the action of the stirring component, the rotation of the roller shaft drives the swing plate to rotate. The swing plate can convey the fish balls to the front of the transfer bin. Then, the fish balls will be conveyed by the feeding equipment. When the fish balls move to the top of the feeding equipment, they will fall onto the surface of the blanking plate and finally fall from the blanking plate to complete the conveying operation of the cooled fish balls.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By setting the pressure feeding mechanism, the fish balls will be covered inside the bottom frame, and the pressing plate descends to the bottom of the pressure feed bin. The cooked fish balls will be driven by the pressing plate to descend to the bottom of the cold water. It can quickly press the cooked fish balls to the bottom of the cold water, which can accelerate their cooling speed. This method utilizes the temperature difference between the cold water and the hot fish balls, and shortens the cooling time through rapid cooling, effectively improving the cooling speed of the fish balls, accelerating the working efficiency. Then, under the action of the discharge channel, the fish balls will first be conveyed from the pressure feed bin to the filtering bin. The smaller fish balls or broken fish balls will, under the action of their own buoyancy, pass through the filter net and float on the water surface inside the filtering bin, while other fish balls will be conveyed into the transfer bin, reducing the errors and wastes in manual operation.

Detailed implementation manners

[0027] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners.

[0028] Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Such as Figure 1 - Figure 8A circulating water cooling device for fish ball production as shown, includes a cold material bin 1. A reinforcing strip 2 is fixedly arranged on the end face at the top of the cold material bin 1. A back plate 6 is fixedly installed on the back of the cold material bin 1. A first baffle 3 and a second baffle 4 are fixedly installed inside the cold material bin 1. The first baffle 3 is close to the back plate 6, and the second baffle 4 is in front of the first baffle 3. The first baffle 3 and the second baffle 4 divide the interior of the cold material bin 1 into a material pressing bin, a filtering bin and a conveying bin. The material pressing bin is at the back of the cold material bin 1, the conveying bin is in front of the cold material bin 1, and the filtering bin is between the material pressing bin and the conveying bin. A material pressing mechanism 5 is arranged inside the material pressing bin. A discharge channel 23 is installed inside the cold material bin 1. The surface of the discharge channel 23 penetrates through the first baffle 3 and the second baffle 4. By setting the material pressing mechanism 5, the cooked fish balls can be quickly pressed to the bottom of the cold water, which can accelerate their cooling speed and improve efficiency. Then, under the action of the discharge channel 23, the fish balls will be first transported from the material pressing bin to the filtering bin. The fish balls with smaller size or broken ones will float on the water surface inside the filtering bin by their own buoyancy through the filter net 24, and other fish balls will be transported to the inside of the conveying bin.

[0030] A water circulation component is arranged at the bottom of the cold material bin 1. The water inlet of the water circulation component is in front of the conveying bin, and the water outlet of the water circulation component penetrates through the reinforcing strip 2 and is installed in the material pressing bin. The water circulation component can circulate the cold water inside the conveying bin to the material pressing bin.

[0031] The whole discharge channel 23 is in an inclined state. The end of the discharge channel 23 inside the material pressing bin is the feed inlet, and the end of the discharge channel 23 inside the conveying bin is the discharge outlet. The horizontal height of the discharge outlet is higher than that of the feed inlet. A matching edge 25 is fixedly installed at the end of the feed inlet. The bottom of the matching edge 25 is fixedly connected to the bottom surface of the material pressing bin. A filter net 24 is arranged in the middle of the discharge channel 23. The filter net 24 is in the filtering bin. When the fish balls enter the inside of the discharge channel 23, due to the overall inclination of the discharge channel 23, the fish balls will be first transported from the material pressing bin to the filtering bin. The fish balls with smaller size or broken ones will float on the water surface inside the filtering bin by their own buoyancy through the filter net 24, and other fish balls will be transported to the inside of the conveying bin.

[0032] On the surface of the back plate 6, two guiding grooves 7 are symmetrically opened. A rib 8 is fixedly installed on the inner wall of the guiding groove 7. The pressing mechanism 5 includes a pressing plate 12. At one end of the pressing plate 12 close to the back plate 6, two sliding blocks 17 are provided. A groove 18 is opened on the surface of the sliding block 17. The two sliding blocks 17 are respectively slidably arranged in the two guiding grooves 7, and the rib 8 is slidably clamped in the groove 18. A collar 15 is installed at the end of the pressing plate 12 close to the back plate 6. A polished rod 16 is rotatably installed inside the collar 15. A sleeve 19 is movably sleeved on the middle surface of the polished rod 16. A rectangular surface 20 is fixedly arranged at the top of the sleeve 19. A reinforcing frame 21 is installed on the top of the back plate 6. A cylinder 22 is fixedly installed inside the reinforcing frame 21. The output end of the cylinder 22 is fixedly connected to the rectangular surface 20. The cylinder 22 can drive the pressing plate 12 to descend. The sliding block 17 will gradually slide down inside the guiding groove 7. At this time, the fish balls will be covered inside the bottom frame 13. The pressing plate 12 descends to the bottom of the pressing bin. The cooked fish balls will be driven by the pressing plate 12 to descend to the bottom of the cold water, accelerating their cooling speed. The top of the pressing plate 12 is set as an inclined surface. Then when the pressing plate 12 is lifted, due to the top of the pressing plate 12 being set as an inclined surface, the fish balls on the surface of the pressing plate 12 will roll down from the inclined surface.

[0033] Below the guiding groove 7, a rotating groove 9 is provided. The horizontal height of the rotating groove 9 is the same as that of the feeding port. A spring 10 is arranged inside the rotating groove 9. An L-shaped baffle 11 is installed at the top of the spring 10. The L-shaped baffle 11 is movably arranged inside the rotating groove 9, and the front end of the L-shaped baffle 11 is in front of the rotating groove 9. One end of the pressing plate 12 away from the back plate 6 is directly above the mating edge 25. A bottom frame 13 is fixedly installed at the bottom of the pressing plate 12. A slope 14 is arranged on the surface of the front end of the bottom frame 13. When the sliding block 17 slides from the guiding groove 7 into the rotating groove 9, the front end of the pressing plate 12 will rest on the top of the mating edge 25. The cylinder 22 drives the pressing plate 12 to continue descending. Since the front end of the pressing plate 12 is blocked by the mating edge 25, the other end of the pressing plate 12 will rotate around the polished rod 16. The sliding block 17 will rotate inside the rotating groove 9. Finally, the pressing plate 12 will be in an inclined state. The pressing plate 12 will be parallel to the discharge channel 23. The fish balls will move into the discharge channel 23 under the action of their own buoyancy.

[0034] Two baffle plates 30 are symmetrically installed inside the pressing bin. The width of the pressing plate 12 is the same as the width of the mating edge 25. The end of the mating edge 25 is fixedly connected to the surface of the baffle plate 30. The baffle plate 30 can limit the pressing plate 12 and the fish balls. When the pressing plate 12 drives the fish balls to descend, the fish balls will be limited among the pressing plate 12, the baffle plate 30, the pressing bin and the mating edge 25, preventing the fish balls from deviating.

[0035] Inside the transfer bin, a stirring assembly 26 is installed. The stirring assembly 26 includes a roller shaft, and swing plates are arranged on the surface of the roller shaft. At the front end inside the transfer bin, a feeding device 27 is installed. The feeding device 27 is arranged in an inclined shape. At the front end of the cold material bin 1, two vertical plates 28 are symmetrically arranged. A blanking plate 29 is fixedly installed between the two vertical plates 28. The blanking plate 29 cooperates with the feeding device 27. The fish balls entering the transfer bin will, under the action of the stirring assembly 26, the rotation of the roller shaft drives the swing plates to rotate. The swing plates can convey the fish balls to the front of the transfer bin. Then, the fish balls are conveyed by the feeding device 27. When the fish balls move to the top of the feeding device 27, they will fall onto the surface of the blanking plate 29 and finally fall from the blanking plate 29 to complete the conveying operation of the cooled fish balls.

[0036] A water circulation cooling processing method for fish ball production is as follows:

[0037] S1. First, the staff injects the cooked fish balls into the pressing bin from both sides of the pressing bin. The water outlet of the water circulation assembly can push the fish balls to the middle of the pressing bin. Then, the air cylinder 22 drives the pressing plate 12 to descend. The sliding block 17 will gradually slide down inside the guiding groove 7. At this time, the fish balls will be covered inside the bottom frame 13. The fish balls will be brought by the pressing plate 12 to the bottom of the pressing bin. When the sliding block 17 slides out of the guiding groove 7 and into the rotating groove 9, the front end of the pressing plate 12 will rest on the top of the mating edge 25. The air cylinder 22 drives the pressing plate 12 to continue descending. Since the front end of the pressing plate 12 is blocked by the mating edge 25, the other end of the pressing plate 12 will rotate around the smooth rod 16 as the center. The sliding block 17 will rotate inside the rotating groove 9. Finally, the pressing plate 12 will be in an inclined state and parallel to the discharge channel 23. The fish balls will move into the discharge channel 23 under the action of their own buoyancy.

[0038] S2. When the fish balls enter the discharge channel 23, since the discharge channel 23 is overall inclined, the fish balls will be first conveyed from the pressing bin to the filtering bin. The smaller-sized fish balls will, under the action of their own buoyancy, pass through the filter net 24 and float on the water surface inside the filtering bin, while the other fish balls will be conveyed into the transfer bin.

[0039] S3. The fish balls entering the transfer bin will, under the action of the stirring assembly 26, the rotation of the roller shaft drives the swing plates to rotate. The swing plates can convey the fish balls to the front of the transfer bin. Then, the fish balls are conveyed by the feeding device 27. When the fish balls move to the top of the feeding device 27, they will fall onto the surface of the blanking plate 29 and finally fall from the blanking plate 29 to complete the conveying operation of the cooled fish balls.

[0040] Working principle: First, cold water in the cold material bin 1 is added between the baffle 30 and the reinforcement bar 2. Workers inject the cooked fish balls into the pressure bin from both sides of the pressure bin. The fish balls will float above the baffle 30 and will not exceed the reinforcement bar 2. Then, the water outlet of the water circulation component can push the fish balls to the middle of the pressure bin. Next, the cylinder 22 drives the pressing plate 12 to descend, and the sliding block 17 will gradually slide down inside the guiding groove 7. At this time, the fish balls will be covered inside the bottom frame 13, and the fish balls will be brought by the pressing plate 12 to the bottom of the pressure bin. When the sliding block 17 slides from the guiding groove 7 into the rotating groove 9, the front end of the pressing plate 12 will rest on the top of the mating edge 25. The cylinder 22 drives the pressing plate 12 to continue descending. Since the front end of the pressing plate 12 is blocked by the mating edge 25, the other end of the pressing plate 12 will rotate around the smooth rod 16 as the center, and the sliding block 17 will rotate inside the rotating groove 9. Finally, the pressing plate 12 will be in an inclined state, and the pressing plate 12 will be parallel to the discharge channel 23. The fish balls will move into the discharge channel 23 under the action of their own buoyancy. Subsequently, when the pressing plate 12 is lifted, since the top of the pressing plate 12 is set as an inclined surface, the fish balls on the surface of the pressing plate 12 will roll down from the inclined surface. Next, when the fish balls enter the discharge channel 23, since the discharge channel 23 is overall inclined, the fish balls will be first transported from the pressure bin to the filtering bin. The smaller-sized fish balls will, under the action of their own buoyancy, pass through the filter net 24 and float on the water surface inside the filtering bin, and the other fish balls will be transported into the conveying bin. Then, the fish balls entering the conveying bin will, under the action of the stirring component 26, the rotation of the roller shaft drives the swing plate to rotate, and the swing plate can convey the fish balls to the front of the conveying bin. Then, the fish balls will be conveyed by the feeding device 27. When the fish balls move to the top of the feeding device 27, they will fall onto the surface of the feeding plate 29 and finally fall from the feeding plate 29 to complete the conveying operation of the cooled fish balls.
