Description

Technical Field

[0001] This utility model relates to the technical field of a multi-functional shrimp backing machine with adjustable backing depth and length, specifically a multi-functional shrimp backing machine with adjustable backing depth and length. Background Technology

[0002] As one of the core raw materials in the global catering and food processing industry, the efficiency and quality of shrimp pre-processing directly determine the quality and added value of the final product. The back-opening process, as a key step in the deep processing of shrimp, not only removes impurities such as shrimp veins to improve food safety, but also enhances the flavor absorption effect by increasing the surface area of ​​the ingredients. It is widely used in the production of frozen prepared shrimp, ready-to-eat seafood snacks, and pre-prepared catering dishes.

[0003] Currently, Chinese patent CN221670857U discloses a shrimp deveining machine, including a main body with a shrimp inlet on one side and a shrimp outlet on the other; a vibration cleaning device located at the outlet of the main body, comprising: a support frame with one end higher than the other, allowing its upper surface to be tilted during use; a vibration frame located at the top of the support frame and hinged to its upper surface, with densely packed filter holes at its bottom; and a vibration motor located at the rear of the vibration frame. A cam drives one end of the vibration frame to periodically rise and fall. When the cam returns to its original position and the vibration frame also falls back to its original position, the vibration frame re-fits the upper surface of the support frame. The support frame pushes the shrimp tails inside the filter holes upwards, preventing them from clogging the filter holes. Furthermore, when the vibration frame returns to its original position and collides with the support frame, it separates the shrimp's internal organs, preventing them from adhering to the shrimp and improving the cleaning effect.

[0004] The above-mentioned shrimp back-opening machine has some problems in actual use. It cannot adjust the cutting depth according to the size of the shrimp. As a result, if small shrimp are opened at a fixed depth, the shrimp meat may be cut through directly and broken into pieces. If the depth is insufficient for large shrimp, the shrimp back may not be fully opened. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This embodiment provides a multi-functional shrimp deveining machine with adjustable deveining depth and length, including a worktable 100, a conveyor belt 101 for conveying shrimp is installed on the surface of the worktable 100, and side guards 102 are fixedly installed on the top of the front and rear sides of the worktable 100 and on both sides of the conveyor belt 101; a deveining component, which is installed above the output end of the conveyor belt 101 by a mounting component, and is used to devein the shrimp; a pressing component, which is located on the left side of the mounting component, and is used to press the shrimp to prevent them from shifting; and a guide component, which is installed between the two sets of side guards 102, and is used to guide the conveyed shrimp to enter the pressing component in sequence. The adjusting component includes a mounting bracket 300 fixedly installed at the bottom of the mounting plate 212. The mounting bracket 300 is U-shaped and the opening of the mounting bracket 300 faces one side. A one-way screw 306 is rotatably connected to the inner cavity of the mounting bracket 300. A nut seat 305 is threadedly connected to the surface of the one-way screw 306. A transmission bar 304 is fixedly connected to one side of the nut seat 305. One end of the transmission bar 304 is fixedly connected to the top of the snap-fit ​​component. A guide hole 309 is provided on one side surface of the mounting bracket 300. A guide rod 308 is slidably connected to the inner cavity of the guide hole 309. One end of the guide rod 308 is fixedly connected to the surface of the nut seat 305. Through the setting of the guide hole 309 and the guide rod 308, and through the setting of the adjusting component, the one-way screw 306 and the nut seat 305 cooperate with the structure of the guide hole 309 and the guide rod 308. When the one-way screw 306 is rotated, under the limiting action of the guide rod 308, the nut seat 305 can drive the cutter 310 to rise and fall smoothly, ensuring the accuracy and stability of the height adjustment of the cutter 310, and thus accurately controlling the back opening depth according to the size of the shrimp.

[0023] The mounting components include mounting rods 201 fixedly installed above the middle of the two sets of retaining edges 102. Mounting rings 202 are fixedly sleeved on the surface of the mounting rods 201, and mounting plates 212 are fixedly installed on the right side of the mounting rings 202. Through the installation of the mounting components, the mounting rods 201 are fixed above the retaining edges 102, ensuring that the installation positions of the mounting rings 202 and the mounting plates 212 are precisely aligned with the conveyor belt 101. This ensures that the back-opening component and the pressing component can accurately act on the shrimp on the conveyor belt 101. In particular, it provides a stable support foundation for the depth adjustment mechanism of the back-opening component, ensuring the accuracy of the back-opening operation after adjustment and avoiding the impact of unstable installation on the back-opening effect of shrimp of different sizes.

[0024] The back-opening component includes a cutter 310 located below the mounting plate 212. A connecting piece 301 extending upward is fixedly connected to the right end of the cutter 310. An adjusting component for adjusting the height of the cutter 310 is connected to the top of the connecting piece 301 via a snap-fit. The adjusting component is installed at the bottom center of the mounting plate 212. Through the setting of the back-opening component, the cutter 310 directly realizes the function of opening the shrimp back. The cooperation between the connecting piece 301 and the snap-fit ​​achieves a stable connection between the cutter 310 and the adjusting component.

[0025] The pressing component includes a pressing plate 200 located below the mounting plate 212. Both sides of the mounting plate 212 have elastic pushers at the bottom to push the pressing plate 200 downwards. The left side of the pressing plate 200 is bent upwards with a rounded corner. An arc-shaped groove 205 for guiding the shrimp is provided at the bottom of the pressing plate 200. An inlet 206 is provided at the top of the pressing plate 200. A cutter 310 passes downwards through the inlet 206 to open the shrimp inside the arc-shaped groove 205. Through the pressing component, the arc-shaped groove 205 at the bottom of the pressing plate 200 can be adapted to the shape of the shrimp, achieving precise positioning. The rounded corner structure on the left side facilitates the smooth entry of the shrimp into the arc-shaped groove 205, preventing obstruction of shrimp transport.

[0026] The snap-fit ​​component includes a fixing clip 302 fixedly connected to the bottom of the transmission bar 304. The fixing clip 302 snaps onto the upper end of the connecting piece 301. A fixing bolt 303 is inserted into one side of the fixing clip 302. The end of the fixing bolt 303 passes through one side of the fixing clip 302 and the connecting piece 301 in sequence and is threaded to the other side surface of the fixing clip 302. Through the setting of the snap-fit ​​component, the cooperation between the fixing clip 302 and the fixing bolt 303 realizes a firm connection between the cutter 310 and the transmission bar 304, while facilitating the disassembly and replacement of the cutter 310.

[0027] The elastic pusher includes ball grooves 207 disposed on the top of both sides of the pressure plate 200. Connecting balls 208 are rotatably connected to the inner cavities of the two sets of ball grooves 207. Threaded rods 210 are fixedly connected to the tops of the two sets of connecting balls 208. Springs 209 are sleeved on the surfaces of the two sets of threaded rods 210. The two ends of the two sets of springs 209 abut against the bottom of the corresponding side of the mounting plate 212 and the top of the corresponding side of the pressure plate 200, respectively. The tops of the two sets of threaded rods 210 extend upwards through the mounting plate 212 and are threadedly connected to limit nuts 211. The bottoms of the two sets of limit nuts 211 are respectively connected to… On the corresponding side top of the mounting plate 212, the spring 209 can apply elastic pressure to the pressure plate 200 through the setting of the elastic pusher. By turning the limit nut 211 to adjust the position of the threaded rod 210, the compression of the spring 209 can be changed, thereby flexibly adjusting the pressing force of the pressure plate 200 on the shrimp, adapting to shrimp of different sizes and textures, avoiding excessive pressing force that damages the shrimp or insufficient pressing force that causes positioning failure. At the same time, the rotational cooperation between the connecting ball 208 and the ball groove 207 allows the pressure plate 200 to slightly adjust its angle as the shrimp is conveyed, improving the fit with the shrimp and further enhancing the pressing and positioning effect.

[0028] The mounting plate 212 has a limiting hole 204 on its left side plane. A limiting rod 203 is slidably connected to the inner cavity of the limiting hole 204. One end of the limiting rod 203 is fixedly connected to one side surface of the mounting ring 202. Through the setting of the limiting hole 204 and the limiting rod 203, the limiting hole 204 on the mounting plate 212 and the limiting rod 203 on the mounting ring 202 form a sliding fit, which restricts the movement direction of the mounting plate 212 and prevents the mounting plate 212 from shifting laterally or shaking during the operation of the equipment.

[0029] The guide includes a limiting plate 103 that is slidably inserted into the surface of the two side guards 102. The two sets of limiting plates 103 are arranged in a figure-eight shape on opposite sides. Through the setting of the guide, the two sets of limiting plates 103 arranged in a figure-eight shape on opposite sides can effectively guide the shrimp on the conveyor belt 101, so that the dispersed shrimp gradually converge and are neatly arranged during the conveying process.

[0030] The worktable 100 is rotatably connected to a bidirectional lead screw 403 at its bottom. A hexagonal block 402 is fitted onto the middle surface of the bidirectional lead screw 403. Nut seats 404 are threaded onto both ends of the bidirectional lead screw 403. Transmission plates 405 are fixedly fitted onto the surfaces of the two sets of nut seats 404. The outer ends of the two sets of transmission plates 405 are bent upwards to the outer side of the corresponding side flange 102. Transmission rods 406 are fixedly connected to the inner upper ends of the two sets of transmission plates 405. The opposite ends of the two sets of transmission rods 406 are fixedly connected to the surfaces of the corresponding side limit plates 103. The bidirectional lead screw 403 can be rotated to adjust... The spacing between the two sets of nut seats 404 drives the limit plate 103 to adjust its position to accommodate shrimp of different widths. By setting the bidirectional screw 403, rotating the bidirectional screw 403 can drive the two sets of nut seats 404 to move towards or away from each other. Then, through the transmission plate 405 and the transmission rod 406, the limit plate 103 is driven to adjust the spacing, realizing flexible adjustment of the guide width. This allows the equipment to adapt to the conveying needs of shrimp of different widths. At the same time, the hexagonal block 402 makes it easy to rotate the bidirectional screw 403 with tools. The transmission structure is stable and ensures the accuracy of the position adjustment of the limit plate 103.

[0031] The workbench 100 has fixed rings 400 on both sides of its bottom. The two ends of the bidirectional lead screw 403 extend into the inner cavity of the corresponding fixed ring 400. The bottom of the two sets of fixed rings 400 are threaded with connecting bolts 401. The ends of the two sets of connecting bolts 401 are threaded upward through the corresponding fixed rings 400 and abut against the corresponding ends of the bidirectional lead screw 403. Tightening the connecting bolts 401 is used to fix the bidirectional lead screw 403 after it is adjusted to the correct position. By setting the fixed rings 400, after the bidirectional lead screw 403 is adjusted to the correct position, tightening the connecting bolts 401 at the bottom of the fixed rings 400 will abut against the ends of the bidirectional lead screw 403, which can effectively fix the bidirectional lead screw 403 and prevent the bidirectional lead screw 403 from rotating during equipment operation, causing the position of the limit plate 103 to shift.

[0032] Working principle; First, rotate the bidirectional lead screw 403 at the bottom of the worktable 100. Through the threaded engagement between the lead screw and the nut seat 404, the two sets of nut seats 404 move towards or away from each other along the lead screw. The nut seats 404 are linked to the two side limit plates 103 through the transmission plate 405 and the transmission rod 406, so that the distance between the two sets of V-shaped limit plates 103 changes to adapt to the width of the shrimp to be processed. After adjustment, tighten the connecting bolt 401 at the bottom of the fixing ring 400, whose end abuts against the end of the bidirectional lead screw 403 to fix the lead screw and prevent the position of the limit plates 103 from shifting. Then, the one-way lead screw 306 inside the rotating mounting bracket 300 is rotated. Under the limiting action of the guide hole 309 and the guide rod 308, the nut seat 305 moves up and down along the lead screw. Through the transmission bar 304, the snap-fit ​​part and the cutter 310 are driven to rise and fall synchronously until the height of the cutter 310 matches the shrimp backing depth requirement. At this time, the fixing clip 302 and the connecting piece 301 are fastened by the fixing bolt 303 to ensure the stability of the cutter 310 position. At this point, tighten the limiting nut 211 on the top of the mounting plate 212, and adjust the compression of the spring 209 through the threaded rod 210, thereby changing the downward pushing force of the spring 209 on the pressure plate 200, so that the pressing force of the pressure plate 200 is adapted to the size and texture of the shrimp, ensuring that the shrimp can be pressed tightly without causing damage. The conveyor belt 101 on the surface of the workbench 100 is started, and the shrimp are placed on the conveyor belt 101 for conveying. The side guards 102 on both sides of the conveyor belt 101 can prevent the shrimp from falling off the edge of the conveyor belt 101. At the same time, two sets of V-shaped limit plates 103 guide the shrimp during conveying, so that the shrimp are neatly arranged and enter the working range of the pressing component in sequence. When the shrimp moves along the conveyor belt 101 to below the pressure plate 200, the rounded corner structure on the left side of the pressure plate 200 bends upward and guides the shrimp, allowing the shrimp to smoothly enter the arc groove 205 at the bottom of the pressure plate 200. Under the action of the elastic pusher, the pressure plate 200 continuously applies downward pressing force to the shrimp in the arc groove 205, effectively preventing the shrimp from shifting or lifting up during the back-opening process. The compressed shrimp continue to move along the conveyor belt 101. When it passes under the back-opening component, the cutter 310 at the bottom of the mounting plate 212 passes downward through the inlet 206 at the top of the pressure plate 200 to precisely open the shrimp in the arc groove 205. Furthermore, the mounting plate 212 ensures the relative position of the cutter 310 and the pressure plate 200 is stable during the back-opening process through the sliding engagement of the limiting hole 204 and the limiting rod 203, as well as the fixed connection between the mounting ring 202 and the mounting rod 201, thereby improving the back-opening accuracy.
