A high-efficiency livestock meat cutting pretreatment device

Abstract

This invention relates to the field of livestock meat cutting and pre-processing technology, specifically to a high-efficiency livestock meat cutting and pre-processing device. It includes a frame with a conveyor belt fixed to its inner wall and a mounting bracket installed on top of the frame. The device uses an output motor, a threaded rod, and an adjusting electric push rod to facilitate the movement and descent of the extrusion plate, thereby flattening the edges of pork pieces of different sizes. Then, by moving the electric push rod, trapezoidal block, limiting plate, T-shaped plate, and L-shaped limiting block, a pulling plate applies pressure and pulls the pigskin to straighten it. At this point, a drive motor and a first reciprocating screw continuously move a paddle plate, which paddles the pig leg, exposing the armpit area. This effectively cleans impurities from pigskin folds and hidden areas under the armpit, preventing impurities from affecting subsequent cutting.

Description

Technical Field

[0001] This invention relates to the field of livestock meat cutting and pretreatment technology, specifically to a high-efficiency livestock meat cutting and pretreatment device. Background Technology

[0002] The types of livestock mainly include economic animals such as pigs, cattle, sheep, and poultry (such as chickens and ducks). During daily processing, they are cut into pieces using cutting devices. In order to ensure the precision, efficiency, and quality of cutting, the meat is pre-treated before cutting.

[0003] Before cutting pork, its surface needs to be rinsed to avoid blood or hair residue affecting subsequent cutting. Existing cleaning methods mainly include spraying, soaking, brushing, and incineration using a blowtorch. Among these, spraying has significant advantages: compared to soaking, it is more efficient and water-saving; compared to brushing, it is gentler and does not damage the meat. Therefore, it is widely used in continuous washing operations on assembly lines. However, when cleaning pork, the natural folds on the skin and areas like the armpits of the legs can easily obstruct the flow of water, making it difficult to effectively clean with high-pressure nozzles and blowtorches, potentially affecting the quality of subsequent cutting and making it inconvenient to use. Summary of the Invention

[0004] Therefore, it is necessary to provide an efficient livestock meat cutting and pretreatment device to address the existing technical problems.

[0005] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows: a high-efficiency livestock meat cutting and pre-processing device, including a frame, a conveyor belt fixedly provided on the inner wall of the frame, an mounting frame installed on the top of the frame, and a tossing cleaning mechanism provided on the mounting frame;

[0006] The actuating cleaning mechanism includes a fixed pressure plate, a movable pressure plate, a pull plate, and a cleaning frame disposed above the frame. The movable pressure plate is provided with an output component that causes the pull plate to descend first and then move. The bottom of both the fixed pressure plate and the movable pressure plate is equipped with a squeezing plate via a first spring telescopic rod. Diverter pipes are respectively installed on opposite sides of the cleaning frame. Multiple high-pressure nozzles are installed at intervals on one diverter pipe, and multiple flame nozzles are installed at intervals on the other diverter pipe. An installation rod is installed on the top of the fixed pressure plate, and a lever is slidably installed on the installation rod. A translation component is provided on the installation frame that allows the lever, the fixed pressure plate, the movable pressure plate, and the cleaning frame to move.

[0007] Furthermore, the output component includes two fixed frames installed on the side of the movable pressure plate. Each fixed frame has a limiting rod installed inside it.

[0009] Furthermore, the adjustment assembly includes a slide groove on the side of the mounting bracket, a slide rod installed in the slide groove, a lifting slide seat slidably sleeved on the slide rod, a fixed pressure plate installed on the lifting slide seat, a fixed rod installed on the side of the lifting slide seat, a fixed hole opened on the side of the movable pressure plate, the fixed rod slidingly passing through the fixed hole, an output motor installed on the side of the mounting bracket, an adjustment groove opened on the upper part of the mounting bracket, a threaded rod rotatably installed in the adjustment groove, one end of the threaded rod extending outside the mounting bracket and fixedly connected to the output shaft of the output motor, an adjustment block threadedly sleeved on the threaded rod, an adjustment electric push rod installed at the bottom of the adjustment block, a movable pressure plate installed at the movable end of the adjustment electric push rod, and pressure sensors installed at the bottom of both the fixed pressure plate and the movable pressure plate.

[0010] Furthermore, the transmission assembly includes a movable slot formed on the mounting frame, in which a second reciprocating screw is rotatably mounted. A first sprocket is sleeved on the first reciprocating screw, and a second sprocket is mounted on the second reciprocating screw. The first sprocket and the second sprocket are connected by a first chain. A T-shaped slide is threaded onto the second reciprocating screw. A movable cavity is formed on the T-shaped slide, in which a rotating rod is rotatably mounted. Both ends of the rotating rod extend outside the T-shaped slide and are respectively mounted with movable plates. The cleaning frame is mounted on the bottom of the two movable plates. The mounting frame is provided with a linkage assembly that causes the rotating rod to oscillate periodically. The linkage assembly is installed in conjunction with the second reciprocating screw.

[0011] Furthermore, the linkage assembly includes a fixed plate installed within the movable cavity, a third reciprocating screw rotatably mounted on the fixed plate, a rack threaded onto the third reciprocating screw, a movable rod rotatably mounted on the mounting bracket, a meshing incomplete gear and a spur gear respectively mounted on the ends of the second reciprocating screw and the movable rod near the drive motor, the other end of the movable rod being fitted with a rectangular rod, a rectangular hole being opened at one end of the third reciprocating screw, the rectangular rod slidingly extending into the rectangular hole, and a ring gear fitted onto the rotating rod, the ring gear meshing with the rack.

[0012] Furthermore, the diameter of the first sprocket is smaller than the diameter of the second sprocket, and the diameter of the incomplete gear is larger than the diameter of the sprocket.

[0013] Furthermore, a movable rod is rotatably mounted on the frame, and a cleaning roller is mounted on the movable rod. A third sprocket is mounted on the end of the first reciprocating screw away from the drive motor, and a fourth sprocket is mounted on the other end of the movable rod outside the frame. The third sprocket and the fourth sprocket are connected by a second chain.

[0014] Furthermore, a support block is installed on the top of the cleaning frame, a movable electric push rod is installed on the side of the support block, an L-shaped moving plate is installed on the movable end of the movable electric push rod, and a shielding plate is installed at the bottom of the L-shaped moving plate.

[0015] Furthermore, a support screen plate is installed inside the frame, and the support screen plate is located between the conveyor belts.

[0016] The beneficial effects of this invention compared to the prior art are:

[0017] Firstly, this device uses an output motor, threaded rod, and adjusting electric push rod to facilitate the movement and descent of the extrusion plate, thereby flattening the edges of pork of different sizes and preventing bulges in the middle that would affect the skin-stretching effect. Then, by moving the electric push rod, trapezoidal block, limiting plate, T-shaped plate, and L-shaped limiting block, the stretching plate applies pressure and then pulls the pork skin to straighten it. At this time, the drive motor and the first reciprocating screw cause the paddle plate to move continuously. The continuous movement of the paddle plate 9 will paddle the pork leg, thereby exposing the armpit area, effectively cleaning the pork skin folds and impurities in the hidden areas under the armpit of the pork leg, and preventing impurities from remaining and affecting subsequent cutting.

[0018] Secondly, this device drives the second reciprocating screw to rotate via the first reciprocating screw. With the cooperation of the T-shaped slide, the cleaning frame moves back and forth, which in turn causes the high-pressure nozzle and the burner to move back and forth. At the same time, the rotation of the second reciprocating screw causes the third threaded rod to rotate periodically through the incomplete gear and the circular gear. The periodic rotation of the third reciprocating screw causes the cleaning frame to oscillate periodically through the rack, rotating rod and the ring gear, which in turn causes the orientation angle of the high-pressure nozzle and the burner to change. This allows the rinsing and singeing positions to be better aligned with the folds of the pigskin and complex areas such as the armpits of the pig legs, effectively improving the impurity removal effect.

[0019] Thirdly, this device can move the baffle plate by using a movable electric push rod and an L-shaped moving plate, thereby blocking the flame nozzle when the high-pressure nozzle is used for rinsing and blocking the high-pressure nozzle when the hair is singed, thus avoiding mutual interference and affecting subsequent use.

[0033] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0034] Figures 1-12 This is the preferred embodiment of the present invention, which is described below in conjunction with the accompanying drawings. Figures 1-12 The present invention will be further described below.

[0035] See attached document Figures 1-12A high-efficiency livestock meat cutting and pre-processing device includes a frame 1, a conveyor belt 2 fixedly mounted on the inner wall of the frame 1, an mounting frame 3 mounted on the top of the frame 1, and a tossing cleaning mechanism provided on the mounting frame 3; in this embodiment, the mounting frame 3 is a groove-shaped opening facing downwards, and both sides of the mounting frame 3 are fixedly connected to the frame 1, the conveyor belt 2 passes through the lower side of the mounting frame 3, and the conveyor belt 2 is a mesh conveyor belt.

[0036] The actuating cleaning mechanism includes a fixed pressure plate 12, a movable pressure plate 15, a pull plate 24, and a cleaning frame 45, all mounted above the frame 1. The movable pressure plate 15 is equipped with an output component that causes the pull plate 24 to descend first and then move. The fixed pressure plate 12 and the movable pressure plate 15 are arranged side-by-side, both positioned above the conveyor belt 2. Two first spring telescopic rods 19 are installed at the bottom of both the fixed pressure plate 12 and the movable pressure plate 15. The two first spring telescopic rods 19 of the fixed pressure plate 12 and the two first spring telescopic rods 19 of the movable pressure plate 15 are also equipped with… The cleaning frame 45 is equipped with a squeezing plate 20 and is located on the upper side of the fixed pressure plate 12 and the movable pressure plate 15. Diverter pipes 46 are installed on opposite sides of the cleaning frame 45. Multiple high-pressure nozzles are fixedly installed on one diverter pipe 46 and multiple flame nozzles are fixedly installed on the other diverter pipe 46. A horizontally placed L-shaped mounting rod 14 is installed on the top of the fixed pressure plate 12. A lever 9 is slidably installed on the mounting rod 14 and can move horizontally along the mounting rod 14. The mounting frame 3 is equipped with a translation component that allows the lever 9, the fixed pressure plate 12, the movable pressure plate 15 and the cleaning frame 45 to move.

[0037] In this embodiment, each diversion pipe 46 is provided with several branch pipes, and the branch pipes on two diversion pipes 46 are arranged alternately. Several flame nozzles are arranged at intervals on the branch pipes on one diversion pipe 46, and several high-pressure nozzles are arranged at intervals on the branch pipes on the other diversion pipe 46.

[0038] With the above structure, before use, the external gas and water pipes are first connected to the two branch pipes 46 via flexible hoses. The cut livestock meat is placed on the conveyor belt 2. In this embodiment, pork is used as an example. The pork skin is facing upwards and located on one side of the conveyor belt 2 to ensure that one side of the pork is aligned with the fixed pressure plate 12. The conveyor belt 2 moves the pork. When the pork moves directly under the mounting frame 3, the conveyor belt 2 stops moving. At this time, the movable pressure plate 15 is moved by the translation component and aligned with the other edge of the pork. The fixed pressure plate 12 and the movable pressure plate 15 descend and press the two sides of the pork with the two extrusion plates 20 respectively. Due to the presence of the first spring telescopic rod 19, the pork is pressed tightly while avoiding excessive load that could affect the quality of the pork. Due to the extrusion of the fixed pressure plate 12 and the movable pressure plate 15, the pork is pressed tightly. The edges of the meat are flattened, and then the translation component causes the paddle plate 9 to move back and forth. The movement of the paddle plate 9 will paddle the pig leg, thereby exposing the armpit area, which effectively cleans the impurities in the folds of the pig skin and the armpit area of ​​the pig leg, preventing impurities from remaining and affecting subsequent cutting. At the same time, the translation component will cause the cleaning frame 45 to move and swing back and forth. During the movement and swinging of the cleaning frame 45, the movement and orientation angle of the high-pressure nozzle and the flame nozzle will change, so that they will periodically adjust their angle while moving, so that the rinsing and singeing positions are better aligned with the folds of the pig skin and complex areas such as the armpit of the pig leg, effectively improving the impurity cleaning effect.

[0039] like Figure 5 , Figure 7 and Figure 8As shown, the output component includes two fixed frames 22 spaced apart on the side of the movable pressure plate 15. Each fixed frame 22 has a limit rod installed inside it, and a movable frame is slidably fitted onto each limit rod. The movable frames are slidably disposed within the fixed frames 22. T-shaped plates 23 are slidably installed on each movable frame, with the movable frames sliding horizontally along the limit rods and the T-shaped plates 23 sliding vertically. A pull plate 24 is installed at the bottom of the two T-shaped plates 23. A movable frame 25 is installed on the top of the movable pressure plate 15, and a movable electric actuator 26 is installed inside the movable frame 25. A U-shaped plate 27 is installed at the movable end of the movable electric actuator 26, and two trapezoidal blocks 28 are installed at the bottom of each end of the U-shaped plate 27. The tops of the two fixed frames 22 are each equipped with... The top of the L-shaped limiting block 56 and the T-shaped plate 23 are located between the corresponding L-shaped limiting block 56 and trapezoidal block 28. The side of the T-shaped plate 23 near the L-shaped limiting block 56 is provided with an inclined part that gradually moves away from the trapezoidal block 28 from bottom to top. The side of the trapezoidal block 28 near the T-shaped plate 23 is an inclined pushing part that gradually moves away from the T-shaped plate 23 from bottom to top. The pushing part and the inclined part cooperate with each other. Limiting plates 29 are installed at the bottom of the two trapezoidal blocks 28 on the side away from the T-shaped plate 23. Springs 57 are installed in both moving frames. Both springs 57 are in a compressed state and push the moving frames to move away from the moving frame 25. A U-shaped protective shell with an opening facing downward is installed on the side of the U-shaped plate 27. The U-shaped protective shell slides around the moving frame 25.

[0040] Specifically, the T-shaped plate 23 can move laterally through the fixed frame 22, the limiting rod, and the movable frame. The movable electric push rod 26, the U-shaped plate 27, and the trapezoidal block 28 can provide a horizontal pushing force to the T-shaped plate 23. At this time, since the T-shaped plate 23 is blocked by the L-shaped limiting block 56, under the action of the pushing part and the tilting part, the T-shaped plate 23 can only move downward along the L-shaped limiting block 56. When the T-shaped plate 23 is misaligned with the trapezoidal block 28, as the movable electric push rod 26 continues to move, the T-shaped plate 23 moves to below the L-shaped limiting block 56. At this time, the trapezoidal block 28 continues to move and will push the T-shaped plate 23 towards the movable frame 25 through the limiting plate 29. This allows the pull plate 24 to be fixed to the pigskin first and then pulled, thereby straightening the pigskin and avoiding wrinkles that affect the cleaning effect. The movable frame 25 and the U-shaped protective shell facilitate the protection of the movable electric push rod 26.

[0041] like Figure 1 and Figure 5As shown, the translation component includes a crossbeam 4 mounted on the side of the mounting frame 3. A mounting groove is provided on one side of the crossbeam 4, and a first reciprocating screw 5 is rotatably mounted in the mounting groove. A drive motor 6 is mounted on the side of the crossbeam 4. One end of the first reciprocating screw 5 extends outside the crossbeam 4 and is connected to the output shaft of the drive motor 6. A translation slide 8 is threaded onto the first reciprocating screw 5. One side of the translation slide 8 is slidably disposed in the mounting groove. A mounting hole is provided on the top of the translation slide 8, and a second spring telescopic rod is mounted on the mounting hole. A lever 9 is mounted on the second spring telescopic rod. An adjustment component is provided on the mounting frame 3 to move the fixed pressure plate 12 and the movable pressure plate 15. A transmission component is provided on the mounting frame 3 to move and swing the cleaning frame 45. The transmission component is installed in cooperation with the first reciprocating screw 5.

[0042] In this design, the crossbeam 4, the first reciprocating lead screw 5, the drive motor 6, the translation slide 8, and the second spring telescopic rod are arranged to facilitate the reciprocating movement of the lever 9.

[0043] Specifically, the pig's leg can be moved by the reciprocating movement of the lever 9, thereby exposing the armpit area and making it easier to clean the armpit area.

[0044] like Figure 4 and Figure 5 As shown, the adjustment assembly includes a slide groove on the side of the mounting frame 3, the slide groove is vertically arranged, a vertical slide rod 10 is installed in the slide groove, a lifting slide 11 slides on the slide rod 10, one side of the lifting slide 11 is slidably arranged in the slide groove, a fixed pressure plate 12 is fixedly connected to the lifting slide 11, a fixed rod 13 is installed on the side of the lifting slide 11, a fixed hole is opened on the side of the movable pressure plate 15, the fixed rod 13 slides through the fixed hole, an output motor 7 is installed on the side of the mounting frame 3, a horizontal adjustment groove is opened on the top of the mounting frame 3, a threaded rod 16 is rotatably installed in the adjustment groove, and the threaded rod 16... One end of 6 extends to the outside of the mounting bracket 3 and is connected to the output shaft of the output motor 7. An adjusting block 17 is threaded on the threaded rod 16. One side of the adjusting block 17 is slidably disposed in the adjusting groove. An adjusting electric push rod 18 is installed at the bottom of the adjusting block 17. A movable pressure plate 15 is installed at the movable end of the adjusting electric push rod 18. Pressure sensors 21 are installed at the bottom of both the fixed pressure plate 12 and the movable pressure plate 15. The pressure sensors 21 are connected to the corresponding side of the squeezing plate 20. Specifically, a vision sensor can be installed on the side of the movable pressure plate 15 so that the movable pressure plate 15 automatically aligns with the edge of the pork during use.

[0045] In this design, the positions of the fixed pressure plate 12 and the movable pressure plate 15 are easily adjusted by setting up the output motor 7, slide bar 10, lifting slide 11, fixed rod 13, threaded rod 16, adjusting block 17, and adjusting electric push rod 18.

[0046] Specifically, the placement of the output motor 7, threaded rod 16, and adjusting block 17 facilitates the adjustment of the position of the movable pressure plate 15, aligning it with the other edge of the pork. The placement of the electric push rod 18 facilitates the downward movement of the movable pressure plate 15. The placement of the slide rod 10, lifting slide 11, and fixing rod 13 ensures that the movable pressure plate 15 can still move down synchronously with the fixed pressure plate 12 after being moved. The placement of the pressure sensor 21 facilitates the detection of the squeezing force of the squeezing plate 20, preventing excessive force from damaging the pork.

[0047] like Figure 3 , Figure 4 , Figure 9 and Figure 12 As shown, the transmission assembly includes a downward-facing movable groove on the top of the mounting frame 3. A second reciprocating screw 30 is rotatably mounted in the movable groove. The end of the first reciprocating screw 5 away from the drive motor 6 extends to the outside of the crossbeam 4 and is fitted with a first sprocket 31. One end of the second reciprocating screw 30 extends to the outside of the mounting frame 3 and is fitted with a second sprocket 32. The first sprocket 31 and the second sprocket 32 ​​are connected by a first chain 33. A T-shaped slide 34 is threaded onto the second reciprocating screw 30. The upper part of the T-shaped slide 34 is slidably disposed in the movable groove. A movable cavity is formed on the T-shaped slide 34. A rotating rod 42 is rotatably mounted in the movable cavity. Both ends of the rotating rod 42 extend to the outside of the T-shaped slide 34 and are respectively fitted with movable plates 44. A cleaning frame 45 is mounted on the two movable plates 44. A linkage assembly is provided on the mounting frame 3 to make the rotating rod 42 swing periodically. The linkage assembly is connected to the second reciprocating screw 30.

[0048] In this design, the arrangement of the movable groove, the second reciprocating lead screw 30, the first sprocket 31, the second sprocket 32, the first chain 33, the T-shaped slide 34, the rotating rod 42, and the movable plate 44 facilitates the reciprocating movement of the cleaning frame 45.

[0049] Specifically, the first sprocket 31, the second sprocket 32, and the first chain 33 can cause the first reciprocating screw 5 to rotate, which in turn drives the second reciprocating screw 30 to rotate. At the same time, the second reciprocating screw 30 can cause the cleaning frame 45 to move back and forth through the T-shaped slide 34, the rotating rod 42, and the movable plate 44. The reciprocating movement of the cleaning frame 45 will cause the high-pressure nozzle and the flame nozzle to move back and forth continuously through the diverter pipe 46, thereby performing rinsing and singeing operations on different positions and improving the cleaning effect.

[0050] like Figures 9-10As shown, the linkage assembly includes a fixed plate 35 installed in the movable cavity, a third reciprocating screw 36 rotatably mounted on the fixed plate 35, a rack 37 threaded onto the third reciprocating screw 36, a movable rod 38 rotatably mounted on the mounting bracket 3, a matching incomplete gear 39 and a spur gear 40 respectively mounted on the second reciprocating screw 30 and the movable rod 38, a rectangular rod 41 mounted on the other end of the movable rod 38, a round hole opened on the side of the T-shaped slide 34, a rectangular hole opened at the end of the third reciprocating screw 36 directly opposite the round hole, the rectangular rod 41 passes through the round hole and extends into the rectangular hole, a ring gear 43 is sleeved on the rotating rod 42, and the ring gear 43 meshes with the rack 37.

[0051] Specifically, the fixed plate 35, the round hole, and the rectangular hole allow the third reciprocating screw 36 to slide on the rectangular rod 41. When the second reciprocating screw 30 rotates, it causes the rectangular rod 41 to rotate intermittently through the incomplete gear 39 and the spur gear 40. The rectangular rod 41 causes the third reciprocating screw 36 to rotate intermittently through the rectangular hole. The third reciprocating screw 36 causes the rack 37 to move intermittently. The rack 37 intermittently causes the ring gear 43 to rotate intermittently, which in turn causes the rotating rod 42 to rotate intermittently. The rotating rod 42 changes the orientation angle of the high-pressure nozzle and the flame nozzle through the cleaning frame 45 and the diverter pipe 46, thereby allowing the rinsing and singeing positions to be better aligned with the various folds of the pigskin and complex areas such as the armpits of the pig legs, effectively improving the impurity cleaning effect.

[0052] like Figure 3 and Figure 9 As shown, the diameter of the first sprocket 31 is smaller than the diameter of the second sprocket 32, and the diameter of the incomplete gear 39 is larger than the diameter of the spur gear 40. By setting the diameter, the movement distance of each component can also be adjusted to ensure that each component can meet the working requirements when reciprocating.

[0053] In this design, the diameter ratio of the first sprocket 31 and the second sprocket 32 ​​causes the second reciprocating screw 30 to rotate slowly, thereby causing the cleaning frame 45 to move slowly. This avoids moving too fast and affecting the rinsing and dehairing effect. The diameter ratio of the incomplete gear 39 and the spur gear 40 ensures that the angle of the high-pressure nozzle and the flame nozzle can be changed while increasing the clearance for adjusting the angle, thus avoiding excessive adjustment.

[0054] like Figure 12 As shown, a movable rod 50 is rotatably mounted on the frame 1, a cleaning roller 51 is mounted on the movable rod 50, a third sprocket 52 is mounted on the end of the first reciprocating screw 5 away from the drive motor 6, a fourth sprocket 53 is mounted on the movable rod 50, and the third sprocket 52 and the fourth sprocket 53 are connected by a second chain 54.

[0055] In this design, the installation of the moving rod 50, cleaning roller 51, third sprocket 52, fourth sprocket 53, and second chain 54 facilitates the cleaning of the conveyor belt 2.

[0056] Specifically, by setting up the moving rod 50, the third sprocket 52, the fourth sprocket 53, and the second chain 54, the cleaning roller 51 can rotate at the same time as the first reciprocating screw 5 rotates, thereby cleaning the residual impurities on the conveyor belt 2, thus avoiding the residue of impurities from affecting subsequent use. At the same time, an external nozzle can be added for auxiliary rinsing.

[0057] like Figure 5 , Figure 6 and Figure 11 As shown, a support block is installed on the top of the cleaning frame 45, a movable electric push rod 47 is installed on the side of the support block, an L-shaped moving plate 48 is installed on the movable end of the movable electric push rod 47, and a baffle plate 49 is installed on the bottom of the L-shaped moving plate 48.

[0058] In this design, the support block, movable electric actuator 47, L-shaped movable plate 48, and shielding plate 49 provide a certain degree of protection.

[0059] Specifically, the movable baffle 49 can block the flame nozzle during rinsing and the high-pressure nozzle during hair removal, thereby avoiding mutual interference and affecting subsequent use.

[0060] like Figure 5 , Figure 8 and Figure 12 As shown, a support screen plate 55 is installed on the frame 1. The support screen plate 55 is located between the conveyor belts 2 and directly below the conveyor belts 2. The deflector plate 9 is provided with rounded corners, and the bottom of the pull plate 24 is provided with multiple anti-slip protrusions.

[0061] In this design, the support screen plate 55 facilitates the support of the conveyor belt 2 when the edge is squeezed, the rounded corners of the push plate 9 reduce the damage to the pig leg caused by the push, and the anti-slip protrusions prevent slippage and facilitate the pulling of the pig skin after the pull plate 24 applies force to the pig skin.

[0062] The working principle of this device is as follows: Before use, first connect the external gas pipeline and water pipeline to the two branch pipes 46 through the hose. Then, place the cut pork on the conveyor belt 2, align one side of the pork with the movable pressure plate 15, and make the pork skin face up. Then start the conveyor belt 2. The start of the conveyor belt 2 will drive the pork to move. When the pork moves to the bottom of the mounting frame 3, the conveyor belt 2 stops moving.

[0063] When conveyor belt 2 stops moving, the high-pressure nozzles first spray water to rinse the pork. Then, the output motor 7 is started, which drives the threaded rod 16 to rotate, thereby moving the adjusting block 17. The adjusting block 17 then moves the movable pressure plate 15 through the adjusting electric push rod 18. When the movable pressure plate 15 moves to the edge of the pork, the output motor 7 stops running, and the adjusting electric push rod 18 outputs, causing the movable pressure plate 15 to move down. The downward movement of the movable pressure plate 15, under the action of the sliding rod 10 and the fixed rod 13, will drive the lifting slide 11 to move down, thereby causing the fixed pressure plate 12 to move down synchronously. The fixed pressure plate 12 and the movable pressure plate 15 are connected by the first spring telescopic rod 1. 9 moves the pressing plate 20 downwards, pressing the pork on both sides. Simultaneously, the fixed pressing plate 12 and the movable pressing plate 15 move downwards, causing the mounting rod 14 and the fixed frame 22 to move downwards respectively. The downward movement of the mounting rod 14 and the fixed frame 22 causes the lever plate 9 and the pull plate 24 to move downwards. When the pressing plate 20 presses the pork, the pull plate 24 is at the top of the pork skin and in contact with it. At this time, the moving electric push rod 26 moves the U-shaped plate 27, which in turn moves the trapezoidal block 28 and the limiting plate 29. The trapezoidal block 28 presses the T-shaped plate 23. At this time, the L-shaped limiting block 56 limits the T-shaped plate 23, allowing it to move downwards only. The downward movement of the T-shaped plate 23 causes the pull plate 24 to move downwards. When the T-shaped plate... When the top of T-plate 23 is misaligned with trapezoidal block 28, pull plate 24 applies pressure to pigskin. Simultaneously, L-shaped limit block 56 does not limit T-plate 23. Then, the moving electric actuator 26 continues to move, causing limit plate 29 to press against T-plate 23. At this time, T-plate 23 moves laterally under the action of limit rod and moving frame. The lateral movement of T-plate 23 causes pull plate 24 to move, thus stretching the pigskin and making it taut. Then, drive motor 6 is turned on, driving the first reciprocating screw 5 to rotate. The rotation of the first reciprocating screw 5 causes translational slide 8 to reciprocate. The reciprocating movement of translational slide 8 causes the lever 9 to reciprocate via the second spring telescopic rod. The movement will pry the pig leg, exposing the armpit area. Once cleaning is complete, the above operation is repeated, and the flame nozzle is used to spray flames, effectively cleaning the pigskin folds and impurities in the pig leg armpit area, preventing impurities from remaining and affecting subsequent cutting. At the same time, moving the electric push rod 26 allows the pigskin to be periodically stretched and relaxed. When the pigskin rebounds, it generates local shear force, causing the skin surface to continuously deform and loosen, making it easier to break the adhesion between impurities and the skin surface. When cleaning is complete, moving the electric push rod 26 moves the U-shaped plate 27. At this time, under the action of the spring 57, the T-shaped plate 23 will return to its original position, thereby canceling the force and pulling on the pigskin, making it easy to use next time.

[0064] When the first reciprocating screw 5 rotates, it causes the first sprocket 31 to rotate. The rotation of the first sprocket 31 causes the second sprocket 32 ​​to rotate via the first chain 33. The rotation of the second sprocket 32 ​​causes the second reciprocating screw 30 to rotate. The rotation of the second reciprocating screw 30 causes the T-shaped slide 34 to move. The movement of the T-shaped slide 34 causes the cleaning frame 45 to move via the rotating rod 42 and the movable plate 44. The movement of the cleaning frame 45 causes the high-pressure nozzle and the flame nozzle to move via the diverter pipe 46, thereby performing rinsing and singeing operations on different positions. At this time, under the action of the fixed plate 35, the third reciprocating screw 36 slides on the rectangular rod 41. At the same time, the rotation of the second reciprocating screw 30 causes the incomplete gear 39 to rotate. The rotation of wheel 39 causes the spherical gear 40 to rotate intermittently, which in turn causes the movable rod 38 to rotate intermittently. The movable rod 38 drives the rectangular rod 41 to rotate intermittently. Under the action of the rectangular hole, the rectangular rod 41 causes the third reciprocating screw 36 to rotate intermittently. The third reciprocating screw 36 drives the ring gear 43 to rotate intermittently through the rack 37, which in turn causes the rotating rod 42 to rotate intermittently. The rotating rod 42 causes the cleaning frame 45 to rotate intermittently through the movable plate 44, which changes the orientation angle of the high-pressure nozzle and the flame nozzle, so that it moves and periodically adjusts the angle, thereby making the rinsing and singeing positions better aligned with the various folds of the pigskin and complex areas such as the armpits of the pig legs, effectively improving the impurity cleaning effect.

[0065] When the first reciprocating screw 5 rotates, it causes the third sprocket 52 to rotate. The rotation of the third sprocket 52 causes the fourth sprocket 53 to rotate via the second chain 54. The rotation of the fourth sprocket 53 causes the moving rod 50 to rotate. The rotation of the moving rod 50 causes the cleaning roller 51 to rotate. At this time, under the action of the external nozzle, the residual impurities on the conveyor belt 2 can be cleaned, thereby avoiding the residue of impurities from affecting subsequent use.

[0066] When rinsing or dehairing, the movable electric actuator 47 is activated. The output of the movable electric actuator 47 causes the L-shaped moving plate 48 to move. The movement of the L-shaped moving plate 48 causes the shielding plate 49 to move, thereby shielding the high-pressure nozzle or flame nozzle, thus avoiding the impact on the flame nozzle during rinsing and the impact on the high-pressure nozzle during dehairing.

[0067] It should be noted that, in this embodiment, the reciprocating lead screw refers to a lead screw that drives the slider to complete axial reciprocating motion when rotating in one direction.

[0068] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
