Description

Technical Field

[0001] This invention relates to the field of fish ball production equipment conveying technology, specifically to a self-feeding device for a fish ball production line. Background Technology

[0002] The fish ball production process requires first deboning and skinning fresh fish meat, then mincing it into a paste. Salt, starch, seasonings, and other auxiliary ingredients are added and stirred until the mixture becomes elastic. The paste is then formed into balls using a forming machine or by hand. The fish balls are then cooked in hot water or boiling water until they float, removed, cooled to a suitable temperature, and packaged. Finally, they undergo sterilization, refrigeration, or freezing to complete the production process. In this process, from the fish ball's initial formation to packaging, existing methods often use multiple conveying devices (such as belt conveyors or screw conveyors) to connect multiple processing devices for feeding. This method cannot reduce the conveying process according to actual needs and fully utilize energy. Furthermore, traditional screw conveyors, without modification, can damage the formed fish balls during transport, resulting in a high damage rate. This method cannot meet the connection and conveying requirements of the forming machine and packaging machine, nor the feeding requirements of the packaging machine. Therefore, a self-feeding device for a fish ball production line is proposed. Summary of the Invention

[0011] Preferably, the top of the inclined surface is provided with several air inlets, the positions of which correspond to the positions of the cooling fan.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the fish ball forming machine produces fish balls during operation, the fish balls fall into the inner side of the feed cylinder. Through the inclined buffer of the silicone flexible plate, the fish balls are gradually guided into the inside of the cylinder in the water. Then, the variable frequency servo motor drives the auger mounting frame to rotate, and causes the shaftless spiral pusher plate to rotate, thereby slowly pushing the fish balls that have fallen into the water inside the cylinder. In addition, the electric heating jacket continuously heats the water inside the cylinder, keeping the water temperature in a relatively stable range. As the shaftless spiral pusher plate pushes the fish balls to the inner side of the corrugated flexible tube, the fish balls are pushed into the corrugated flexible tube. The inner side of the flexible tube has matured. At this time, the fish balls gradually float up and float inside the conveyor box. The deceleration servo motor rotates, which drives the transmission roller to rotate and causes the conveyor scraper to scoop up the fish balls from the water. As the hollow conveyor belt rotates, the conveyor scraper gradually pours the fish balls onto one end of the guide plate. The fish balls slide down into the forming trough under the guidance of the guide plate. Then, through the arrangement and limiting of the forming trough, they slide onto the quality inspection conveyor belt of the packaging machine, thus completing the conveying and feeding of the fish balls from forming to packaging. The overall production process is shortened, and the conveying connection and feeding equipment are reduced. Overall, the consumption is reduced and the production efficiency is indirectly improved.

[0016] 2. When the conveyor box is in operation, the hydraulic telescopic column one and hydraulic telescopic column two adjust their lengths and are connected to the conveyor box through the rotation of the support frame two and support frame one, respectively. This adjusts the tilt position of the conveyor box and allows for a certain range of adjustment of the height and tilt of the conveyor box according to the height of the packaging machine. This adapts the output position of the forming trough to the height of the packaging machine, enabling it to be used on multiple fish ball production lines and adapt to the feeding operations of multiple packaging machines, thus increasing the effectiveness of use.

[0017] 3. During the fish ball maturation process, the cooling fan is started, and an external air pump and steam treatment equipment are connected to the suction hood. At this time, the fish balls are gradually lifted by the perforated conveyor belt and conveyor scraper. The cooling fan blows air onto the perforated conveyor belt and conveyor scraper to cool the fish balls. Some of the hot air is removed through the heat exchanger and heat conduction plate, thereby lowering the temperature. The air pump of the suction hood, together with the cooling fan, forms a guiding effect, reducing steam and lowering the temperature. The fish balls are scooped out of the hot water. The steam is first discharged through the suction hood and drained through the holes of the perforated conveyor belt. Then it is cooled by the heat exchanger and heat conduction plate, and finally it is blown by the cooling fan, achieving a stepped cooling effect. This helps to keep the cooling range of the fish balls within the packaging temperature range. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-10 This invention provides a technical solution: a self-feeding device for a fish ball production line, comprising a cylinder 1 and a conveying box 8. The top of one end of the cylinder 1 is connected to an infeed cylinder 2. A silicone flexible plate 3 is fixedly installed inside the infeed cylinder 2. A water spray nozzle 4 is fixedly sleeved inside the infeed cylinder 2. A variable frequency servo motor 5 is provided at one end of the cylinder 1. The output end of the variable frequency servo motor 5 is driven and connected to an auger mounting frame 501. A shaftless spiral pusher plate 27 is fixedly connected to one side of the auger mounting frame 501. A heat insulation sleeve 6 is fixedly sleeved on the outer side of the cylinder 1 away from the infeed cylinder 2. An electric heating sleeve 26 is sleeved on the opposite side of the heat insulation sleeve 6 and the cylinder 1. A corrugated flexible pipe 7 is connected to the end of the cylinder 1 away from the variable frequency servo motor 5.

[0031] The end of the corrugated flexible pipe 7 away from the cylinder 1 is connected to one end of the conveyor box 8. A heat exchanger 9 is fixedly installed through and embedded in the top of the conveyor box 8. An air suction hood 22 is connected to the top of the end of the conveyor box 8 near the corrugated flexible pipe 7. An inclined surface 11 is fixedly installed at the end of the conveyor box 8 away from the corrugated flexible pipe 7. Several cooling fans 10 are movably installed on the top of the inclined surface 11 through a fan mounting bracket. Two drive rollers 30 are movably installed through the inside of the conveyor box 8 through bearings. A synchronous drive wheel 20 is fixedly installed at one end of each of the two drive rollers 30. A synchronous conveyor belt 21 is meshed and sleeved on the outer side of the synchronous drive wheel 20. Two drive rollers 30 are connected to a geared servo motor 28 at one end. A perforated conveyor belt 24 is movably sleeved on the outside of the two drive rollers 30. Several conveying scrapers 25 are fixedly installed on the outside of the perforated conveyor belt 24. Several perforated holes 2401 are opened inside the perforated conveyor belt 24. A forming groove 12 is movably installed inside the conveyor box 8. A guide plate 23 is fixedly installed at one end of the forming groove 12. Adjusting screws 13 are fixedly installed on both sides of the forming groove 12. The adjusting screws 13 extend movably through to the outside of the wall of the conveyor box 8. A fixing nut 1301 is threaded onto the outside of the adjusting screw 13.

[0032] The working principle of the above technical solution is as follows: During operation, the top of the feeding cylinder 2 is aligned with the extrusion cutting end of the fish ball forming machine, and one end of the forming groove 12 is aligned with the conveyor belt of the packaging machine. When the fish ball forming machine produces fish balls, the fish balls fall into the inner side of the feeding cylinder 2. Through the inclined buffer of the silicone flexible plate 3, the fish balls are gradually guided into the interior of the cylinder 1 in the water. Then, the variable frequency servo motor 5 drives the auger mounting frame 501 to rotate, and causes the shaftless spiral pusher plate 27 to rotate, thereby slowly pushing the fish balls that have fallen into the water inside the cylinder 1. Meanwhile, the electric heating jacket 26 continuously heats the water inside the cylinder 1, keeping the water temperature in a relatively stable range. This allows the fish balls with a diameter of 2-3cm to cook for about 3-5 minutes until the center temperature is ≥70℃. With the push of the shaftless spiral pusher plate 27, the fish balls are further pushed into the water. When the fish balls reach the inside of the corrugated flexible tube 7, they have already matured inside the tube 7 and gradually float to the surface. The fish balls float inside the conveyor box 8. At this point, the reduction servo motor 28 rotates, driving the transmission roller 30 to rotate, which in turn causes the perforated conveyor belt 24 and the conveyor scraper 25 to rotate. The conveyor scraper 25 gradually scoops up the fish balls from the water and, as the perforated conveyor belt 24 rotates, gradually pours the fish balls onto one end of the guide plate 23. The fish balls slide down into the forming trough 12 under the guidance of the guide plate 23, and then slide onto the packaging machine's quality inspection conveyor belt through the arrangement and limiting of the forming trough 12. This completes the conveying and feeding of the fish balls from forming to packaging, reducing the overall production process and the number of conveying connections and feeding equipment, thus reducing overall consumption and indirectly increasing production efficiency.

[0033] In another implementation scheme, such as Figures 1-5As shown, two support legs 29 are fixedly installed at the bottom of the cylinder 1. A support frame 17 is hinged to the bottom of one end of the conveyor box 8 via a pivot. A support leg 18 is fixedly installed at the bottom of the support frame 17. A support frame 14 is hinged to the bottom of the other end of the conveyor box 8 via a pivot. A hydraulic telescopic column 15 is fixedly installed at the bottom of the support frame 14. A support leg 16 is fixedly installed at the bottom of the hydraulic telescopic column 15. Hydraulic telescopic columns 19 are fixedly installed on the opposite sides of the support leg 16 and the support leg 18.

[0034] When the conveyor box 8 is in operation, the hydraulic telescopic column 15 and hydraulic telescopic column 2 19 adjust their lengths and are connected to the conveyor box 8 by the rotation of the support frame 2 17 and support frame 14, respectively. This adjusts the tilt position of the conveyor box 8, allowing the height and tilt of the conveyor box 8 to be adjusted within a certain range according to the height of the packaging machine. This adapts the output position of the forming trough 12 to the height of the packaging machine, thus enabling it to be used on multiple fish ball production lines and to accommodate the feeding operations of multiple packaging machines, thereby increasing the efficiency of use.

[0035] In another implementation scheme, such as Figures 1-8 As shown, the length of the silicone flexible plate 3 is larger than that of the feed cylinder 2. The silicone flexible plate 3 passes through the feed cylinder 2 and extends to the top of the inner cavity of the cylinder 1. The water nozzle 4 is located at the inclined guide of the feed cylinder 2, and the input end of the water nozzle 4 is connected to a water supply pipe.

[0036] The flexible silicone plate 3 acts as a flexible buffer structure, preventing the fish balls from impacting the inner side of the feed cylinder 2 and causing severe deformation when the forming machine outputs the fish balls. After passing through the output port of the forming machine, the fish balls slide down the inclined position of the feed cylinder 2 onto the flexible silicone plate 3. The flexible silicone plate 3 buffers the fish balls and, being inclined, guides them to slide into the inside of the cylinder 1 under the guidance of the flexible silicone plate 3 and the water, thus facilitating subsequent pushing operations. The water flow output from the water nozzle 4 is constant because the heating power of the electric heating jacket 26 for the water inside the cylinder 1 is... The constant temperature ensures that the water inside cylinder 1 remains within a relatively stable temperature range. At this point, the amount of water evaporation and loss is relatively constant. Therefore, the water supply nozzle 4 outputs a relatively stable flow rate to replenish the water inside cylinder 1, thereby cooling the hot water at the inlet section of feed cylinder 2. This keeps the water in that section relatively lower than the water temperature inside cylinder 1, preventing excessive temperature difference between the fish balls and the hot water, which could cause overheating and damage to the surface of the fish balls. This also prevents uneven heating inside the fish balls from affecting rapid surface solidification and ensuring the molding effect. In this way, the water inside the equipment remains relatively stable.

[0037] In another implementation scheme, such as Figures 1-5As shown, the auger mounting bracket 501 extends into the interior of the cylinder 1 through bearings and a rotary seal. The variable frequency servo motor 5 is fixedly mounted on the outside of the cylinder 1 through a bracket. The outside of the auger mounting bracket 501 makes rolling contact with the inner wall of the cylinder 1 through a rubber sleeve. The speed of the variable frequency servo motor 5 is ≤30r / min.

[0038] The rotation speed of the variable frequency servo motor 5 is kept below ≤30r / min, so that the output speed of the shaftless spiral pusher plate 27 is kept within a relatively stable range through the auger mounting frame 501, reducing the damage to the fish balls caused by the shaftless spiral pusher plate 27 due to excessive rotation speed, thereby ensuring the yield of fish balls and ensuring the cooking time of fish balls in the cylinder 1. The auger mounting frame 501 is installed inside one end of the cylinder 1 through traditional sealed bearings and rotating seals, which facilitates the conveying and rotating operation.

[0039] In another implementation scheme, such as Figures 1-10 As shown, the shaftless spiral pusher plate 27 is located on the inner wall of the cylinder 1. The outer side of the shaftless spiral pusher plate 27 is covered with a silicone sleeve 2701. A rounded edge 2702 is fixedly installed on the outer edge of the shaftless spiral pusher plate 27. The outer side of the rounded edge 2702 is in rolling contact with the inner wall of the cylinder 1. The shaftless spiral pusher plate 27 and the cylinder 1 are coaxially arranged.

[0040] The shaftless spiral pusher plate 27 adopts a shaftless spiral conveyor plate, thereby reducing the restriction on the fish balls. The hole in the middle can also facilitate the fish balls to pass through during the maturation and floating process. The flexible covering of the silicone sleeve 2701 reduces the shearing and collision of the fish balls when the shaftless spiral pusher plate 27 rotates, further ensuring the integrity rate of the fish balls, indirectly improving the yield rate and reducing damage. The rounded corner edge 2702 plays the role of rounded corner protection, further reducing the shearing effect of the contact surface between the shaftless spiral pusher plate 27 and the cylinder 1. In addition, the rounded corner can provide a certain sliding support for the shaftless spiral pusher plate 27.

[0041] In another implementation scheme, such as Figures 1-9 As shown, the electric heating sleeve 26 is fixedly sleeved on the outer wall of the cylinder 1. The electric heating sleeve 26 is located on the outer side of the cylinder 1 away from the feed cylinder 2. The cylinder 1 is filled with pure water. The water level of the pure water is higher than the position of the corrugated flexible pipe 7 and lower than the height of the water supply nozzle 4. The water boiling temperature range in the middle section of the cylinder 1 is 90℃-98℃, and the water temperature range inside the feed cylinder 2 is maintained at 77℃-85℃.

[0042] The electric heating jacket 26 heats the inside of the cylinder 1. Water is added inside the cylinder 1, and the water level is maintained at the bottom of the water spray nozzle 4 inside the feed cylinder 2. The water level at the other end is maintained at one end of the conveying scraper 25 and the hollow conveyor belt 24, and the water level line is maintained at the bottom of the corrugated flexible pipe 7 and the inside of the conveying box 8, so as to facilitate the falling fish balls. The conveying scraper 25 picks up the fish balls. The output power of the electric heating jacket 26 is constant, so that the water temperature inside the cylinder 1 is maintained within 90 to 98 degrees Celsius to avoid over-boiling. This is achieved by reducing the frequency conversion servo motor 5. The rotation speed and the length of the cylinder 1 are increased to extend the cooking time of the fish balls in the water, thereby ensuring the fish balls are cooked through. As the heat-insulating sleeve 6 keeps the cylinder 1 and the electric heating sleeve 26 warm, it reduces heat loss. However, the area where the heat-insulating sleeve 6 does not cover the feeding cylinder 2 is subject to heat loss and replenishment through the dripping water from the water supply nozzle 4. This makes the temperature at this location lower than the temperature inside the cylinder 1. The purpose of lowering the temperature at this location is to reduce the temperature of the fish balls entering the water, causing the temperature difference between the fish balls and the water to be too large and thus preventing damage. This ensures the control of the fish ball cooking process and facilitates heating.

[0043] In another implementation scheme, such as Figures 1-9 As shown, the top of the inclined plane 11 is provided with several air inlets 1001, the positions of the air inlets 1001 correspond to the positions of the cooling fan 10, several heat-conducting plates 901 are fixedly installed inside the heat exchanger 9, the heat-conducting plates 901 are fixedly installed through the heat exchanger 9 and extend into the interior of the conveying box 8, the bottom of the suction hood 22 is connected to the top of the inner cavity of the conveying box 8, and the top of the suction hood 22 is provided with a suction pump connector.

[0044] The function of the air inlet 1001 is to guide the output airflow of the cooling fan 10. When the fish balls are being cooked, the cooling fan 10 starts and connects the suction hood 22 to an external air pump and steam treatment equipment. At this time, the fish balls are gradually lifted by the perforated conveyor belt 24 and the conveyor scraper 25. The cooling fan 10 blows air onto the perforated conveyor belt 24 and the conveyor scraper 25 to cool the fish balls. Some of the hot air is removed through the heat exchanger 9 and the heat conduction plate 901, thereby reducing the temperature. The air pump in the suction hood 22, along with the cooling fan 10, forms a guiding effect to remove the steam. As steam decreases and temperature drops, the wind speed of the cooling fan 10 is controlled within a manageable range to reduce the drying effect on the fish balls caused by excessive wind speed. Under the output of the perforated conveyor belt 24 and the conveyor scraper 25, the fish balls ensure a relatively stable temperature reduction. When the fish balls are scooped out of the hot water, the steam is first discharged through the suction hood 22 and drained through the holes of the perforated conveyor belt 24. Then, the fish balls are cooled by the heat exchanger 9 and the heat conduction plate 901, and finally, they are cooled by the blowing action of the cooling fan 10, achieving a stepped cooling effect. This helps to keep the cooling range of the fish balls within the packaging temperature range.

[0045] In another implementation scheme, such as Figures 1-9As shown, the geared servo motor 28 is fixedly installed on the outside of the conveyor box 8, the hollow holes 2401 are linearly filled and evenly distributed inside the hollow conveyor belt 24, and the conveying scraper 25 is circumferentially linearly distributed on the outside of the hollow conveyor belt 24.

[0046] After the geared servo motor 28 is fixed, it rotates and drives the transmission roller 30 to rotate, thereby causing the hollow conveyor belt 24 to rotate. The hollow holes 2401 play the role of draining and ventilation for the hollow conveyor belt 24, and cause the conveyor scraper 25 to pick up the fish balls and drain, cool and transport them when rotating, thus assisting the structure to rotate.

[0047] In another implementation scheme, such as Figures 3-9 As shown, the top surface of the top end of the conveying scraper 25 is provided with a first arc surface 2501, and the bottom surface of the top end of the conveying scraper 25 is provided with a second arc surface 2502.

[0048] The function of the arc position of the first arc surface 2501 is to prevent the fish balls from being squeezed and damaged by the rigid structure when the conveying scraper 25 is scooped up by the perforated conveyor belt 24. The function of the arc position of the second arc surface 2502 is to prevent the fish balls from being squeezed and damaged when the conveying scraper 25 is driven by the perforated conveyor belt 24 and the fish balls are about to roll down. This ensures that the fish balls are not damaged when being scooped up and put down, indirectly increasing the safety of the structure and indirectly ensuring the stability of the fish balls.

[0049] In another implementation scheme, such as Figures 1-9 As shown, one end of the fixing nut 1301 contacts the outer wall of the conveyor box 8 through anti-slip teeth, and both ends of the forming groove 12, the guide plate 23, the hollow conveyor belt 24 and the conveying scraper 25 are in contact with the inner wall of the conveyor box 8.

[0050] When the conveyor box 8 is adjusted in tilt and height to accommodate the height of the packaging machine, the fixing nut 1301 is loosened. At this time, the moving position of the adjusting screw 13 and the side wall of the conveyor box 8 is adjusted, allowing the forming trough 12 and the guide plate 23 to rotate. After adjusting the position of the forming trough 12 and the guide plate 23 according to the conveying position, the fixing nut 1301 is tightened to keep the position of the forming trough 12 and the guide plate 23 stable. Since the forming trough 12 and the guide plate 23 are both lightweight structures, the anti-slip effect of tightening the fixing nut 1301 can maintain the position of the adjusting screw 13, the forming trough 12 and the guide plate 23, making it easy to adjust the position as needed. The positions of the two ends of the forming trough 12, the guide plate 23, the hollow conveyor belt 24 and the conveying scraper 25 ensure that there is no gap between the relative positions of the conveyor box 8 when the fish balls are conveyed, reducing the slippage and damage of the fish balls, and indirectly increasing the stability of the fish ball conveying.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
