Description

Technical Field

[0001] This invention relates to the field of poultry meat processing equipment technology, and in particular to a chicken flattening device. Background Technology

[0002] In the poultry processing industry, especially in chicken processing, chicken meat often needs to be flattened to meet subsequent processing requirements. Traditional manual flattening methods are not only inefficient but also struggle to ensure consistent flattening thickness, severely impacting product quality. While existing mechanical flattening equipment has improved efficiency to some extent, it still suffers from several technical shortcomings: First, most equipment lacks height-adjustable flattening mechanisms, making it impossible to flexibly adjust the height of the flattening rollers according to different product needs; second, continuous operation easily generates meat scraps, and existing equipment often lacks effective cleaning systems, leading to a risk of cross-contamination during processing; third, after prolonged operation, meat scraps and grease easily accumulate in the mesh of the conveyor belt system, and conventional cleaning methods are insufficient to completely remove these residues. Furthermore, existing conveyor systems generally suffer from complex drive structures, making maintenance difficult, and chicken meat tends to stick together during transport, affecting output. These technical deficiencies severely restrict the improvement of production efficiency and product quality in the chicken processing industry. Summary of the Invention

[0024] The support frame refers to the horizontal frame that connects the left and right support plates. It can be assembled from rectangular steel pipes and is used to provide an installation foundation for the mesh conveyor belt.

[0025] Among them, the mesh conveyor belt refers to a circulating conveyor belt with a mesh structure on its surface. It can be made of stainless steel metal mesh or food-grade plastic mesh, used to carry chicken and allow debris to fall through the mesh during the conveying process.

[0026] Among them, the driving component refers to the power device that drives the conveyor belt to move. Specifically, it can be implemented by using a motor in conjunction with a gear or chain transmission structure to maintain the continuous operation of the conveyor belt.

[0028] Among them, a synchronous motor refers to an electric motor whose output shaft speed is synchronized with the power supply frequency. Specifically, it can be implemented using a stepper motor or a servo motor, and is used to precisely control the rotation angle of the screw to achieve height adjustment of the lifting plate.

[0029] The screw refers to a metal rod with helical patterns, which can be implemented using a trapezoidal thread or a ball screw structure, and is used to convert the rotational motion of the motor into the linear motion of the lifting plate.

[0030] The lifting plate refers to the plate-shaped component sleeved on the screw, which can be made of a metal plate with threaded holes, and is used to drive the flattening roller to adjust its position in the vertical direction.

[0031] Among them, the flattening roller refers to a smooth cylindrical roller, which can be made of stainless steel with a polished surface, and is used to apply pressure to the chicken on the conveyor belt to achieve a flattening effect.

[0032] The fixing plate refers to the horizontal plate fixed inside the support plate. It can be achieved by welding or bolting and is used to install the rotating roller and the water outlet pipe.

[0033] The rotating roller refers to a rotatable cylindrical shaft, which can be implemented using a bearing-supported metal shaft, used to drive the brush to rotate and perform cleaning actions.

[0034] Among them, the brush refers to the bristle structure fixed on the surface of the rotating roller, which can be made of nylon or food-grade plastic bristles, and is used to remove residual meat scraps from the surface of the conveyor belt and inside the mesh.

[0035] The water outlet pipe refers to a tubular structure with multiple nozzles, which can be made of stainless steel pipe with quick-release couplings, and is used to spray high-pressure water onto the surface of the conveyor belt to rinse away residues.

[0036] The receiving hopper is a funnel-shaped container located below the support plate. It can be made by welding stainless steel plates and is used to collect wastewater and debris after rinsing.

[0037] The core innovation of this application lies in its dual cleaning mechanism, which integrates rotating brush cleaning and high-pressure nozzle rinsing, combined with an adjustable-height flattening roller structure. This achieves continuous flattening operations while effectively solving the problems of meat residue and hygiene hazards inherent in traditional equipment. The coordinated design of the support frame and mesh conveyor belt not only meets the needs of chicken transportation but also provides operating space for the cleaning system, with the overall structure balancing processing efficiency and hygiene safety.

[0038] The working process and principle of this application are as follows: The chicken flattening device includes support plates at both ends. L-shaped support frames are installed at the front and rear ends of the support plates to provide overall structural support. A support frame is installed between the left and right support plates, and a mesh conveyor belt is fitted on the support frame to transport the chicken to be flattened. A drive component is installed on the support frame to drive the mesh conveyor belt. Fixed frames are fitted at the front and rear ends of the support plates. A synchronous motor is installed on the upper surface of the fixed frame, and the output end of the synchronous motor is connected to a screw. A lifting plate is spirally fitted on the screw. The lifting plates at both ends are rotatably connected to the flattening roller through a first bearing to realize the lifting and lowering adjustment of the flattening roller.

[0039] A fixing plate is installed on the inner side of the support plate. Rotating rollers are mounted on the front and rear ends of the fixing plate via second bearings, and brushes are mounted on the rotating rollers. Multiple water outlet pipes are evenly spaced between the left and right fixing plates, positioned between the brushes at both ends. Multiple high-pressure nozzles are evenly spaced on the lower surface of the water outlet pipes. The fixing plate is located between the support frame and the mesh conveyor belt, and is situated below the support frame. This layout integrates flattening and cleaning functions.

[0040] A hopper is installed on the lower surface of the support plate to collect wastewater and impurities generated during the cleaning process.

[0041] During operation, chicken meat is conveyed via a mesh conveyor belt while flattening rollers flatten it. During flattening, brushes on the rotating rollers clean the conveyor belt, and high-pressure nozzles in the water outlet spray high-pressure water to wash the conveyor belt mesh. The wastewater and impurities are collected in a receiving hopper. This design achieves simultaneous flattening and cleaning, improving processing efficiency and hygiene.

[0042] As a preferred embodiment, the solution of this application is specifically implemented as follows: The chicken flattening equipment has stainless steel support plates on both sides, with L-shaped support frames welded to the front and rear ends of the support plates. The support frames are bolted together between the left and right support plates, and a food-grade plastic mesh conveyor belt is fitted onto the support frames. A motor-driven gear transmission mechanism is mounted on the support frames to drive the mesh conveyor belt.

[0043] The support plate is bolted to the front and rear ends to secure the frame. A synchronous motor is mounted on the upper surface of the frame, and the output shaft of the synchronous motor is connected to a screw rod via a coupling. A lifting plate is spirally fitted onto the screw rod, and the lifting plates at both ends are rotatably connected to the flattening roller via a first bearing. The flattening roller is made of food-grade stainless steel and has a polished surface.

[0044] A fixing plate is welded to the inner side of the support plate. Rotating rollers are mounted on the front and rear ends of the fixing plate via second bearings. Nylon brushes are installed on the outer surface of the rotating rollers. Multiple stainless steel water outlet pipes are installed at equal intervals between the left and right fixing plates, positioned between the brushes at both ends. Multiple high-pressure nozzles, made of ceramic, are installed at equal intervals on the lower surface of the water outlet pipes. The fixing plate is installed below the support frame, below the mesh conveyor belt.

[0045] A stainless steel receiving hopper is installed on the lower surface of the support plate by bolt connection. The receiving hopper has a funnel-shaped design and a drain outlet at the bottom.

[0046] When the equipment is working, the mesh conveyor belt transports chicken at a constant speed. The synchronous motor drives the screw to rotate, which in turn moves the lifting plate up and down, thereby adjusting the height of the flattening rollers to flatten chicken of different thicknesses. At the same time, the rotating rollers drive the brushes to rotate and clean the surface of the conveyor belt. High-pressure nozzles in the water outlet spray high-pressure water to wash the mesh of the conveyor belt. The wastewater and impurities after washing are collected and discharged through the receiving hopper.

[0047] Through the above-described solution, this application achieves spatial integration of the flattening mechanism and the cleaning system, establishing a synchronous cleaning mechanism that effectively solves the problem of difficult removal of residue from conveyor belt mesh in traditional equipment. The screw lifting mechanism enables precise control of the flattening roller height, adapting to the flattening needs of chicken meat of different thicknesses. The three-dimensional cleaning structure combining rotating brushes and high-pressure nozzles improves the cleaning effect of the conveyor belt. This design not only improves the processing efficiency of the equipment but also significantly improves the hygiene quality of the product, reduces the frequency of downtime for cleaning, and extends the continuous operating time of the equipment.

[0048] Please continue reading. Figure 1 and Figure 3As shown, in one embodiment of the present invention, the outer side of the support plate 1 is provided with a water supply pipe 15 for supplying water to the water outlet pipe 14, and the front and rear ends of the outer side of the support plate 1 are provided with a first motor 16 for driving the rotating roller 12 to rotate.

[0049] The water supply pipe extends along the outer side of the support plate and connects directly to the outlet pipe, ensuring a sufficient water supply to the high-pressure nozzles. The first motor is connected to the rotating roller via a transmission mechanism, providing rotational power to the brushes. The water supply pipe is made of pressure-resistant material, with an inner diameter matching the outlet pipe to avoid flow loss. The output shaft of the first motor is fixed to the end of the rotating roller via a coupling, achieving synchronous rotation. The water supply pipe inlet can be connected to an external water source, and the outlet connects to the outlet pipe via a quick-connect coupling for easy maintenance. The first motor features a waterproof design, with a protection level meeting the requirements for humid environments. The water supply pipe is arranged longitudinally along the outer side of the support plate, avoiding the movement trajectory of the lifting plate. The first motor is installed with its axis aligned with the rotating roller to reduce transmission losses.

[0050] Specifically, the water supply pipe introduces external water into the outlet pipe, forming a directional water flow through high-pressure nozzles to wash away meat scraps from the surface of the mesh conveyor belt and within its mesh openings. A primary motor drives rotating rollers to rotate brushes, continuously brushing away adhering substances as the conveyor belt runs. The direct connection between the water supply and outlet pipes avoids pressure attenuation caused by intermediate pipelines, ensuring spray intensity. The primary motor independently controls the rotating rollers at both ends, allowing adjustment of the brush speed according to cleaning needs. During the flattening process, the high-pressure nozzles and rotating brushes work together; the water flow loosens residue, which is then swept into the receiving hopper by the brushes. The water supply pipe is arranged along the outside of the support plate, not occupying internal space and facilitating observation and maintenance. The primary motor, through a reduction mechanism, matches the brush speed to ensure appropriate contact force between the brush bristles and the conveyor belt, effectively cleaning without damaging the mesh belt.

[0051] As a preferred embodiment, the solution of this application is implemented as follows: A water supply pipe is provided on the outer side of the support plate for supplying water to the outlet pipe. A first motor is provided at both the front and rear ends of the outer side of the support plate to drive the rotating roller. The water supply pipe is connected to the outlet pipe through a conduit to ensure a stable water supply. The first motor is connected to the rotating roller through a transmission mechanism to drive the rotating roller.

[0052] Through the above technical solution, this application achieves a stable water supply to the outlet pipe, ensuring sufficient and continuous water volume during the cleaning process. Simultaneously, the rotation of the rotating roller driven by the first motor improves the efficiency and uniformity of brush cleaning, enhancing the cleaning effect on the mesh conveyor belt. This design not only simplifies the equipment structure but also increases the automation level of the cleaning process, reducing the need for manual intervention.

[0053] Please continue reading. Figure 1 , Figure 2 and Figure 6As shown, in one embodiment of the present invention, mounting blocks 51 are provided around the inner wall of the receiving hopper 5. A filter screen 52 is mounted on the mounting block 51 by a first bolt. A drain pipe 53 is connected to the lower surface of the receiving hopper 5. Multiple air inlet pipes 54 are connected at equal distances on the left and right sides of the receiving hopper 5. Each of the multiple air inlet pipes 54 is connected to an air supply pipe 50.

[0054] The mounting block is welded to the inner wall of the receiving hopper around its perimeter. Its top surface has threaded holes for securing the filter screen with a first bolt. The filter screen is made of perforated stainless steel with a hole diameter of 1-2 mm to intercept solid debris. A drain pipe, 50 mm in diameter, is welded to the center of the bottom of the receiving hopper and connects to a wastewater treatment system at its end. Air inlet pipes are 20 mm diameter PVC pipes, horizontally and equidistantly distributed along the left and right side walls of the receiving hopper, with an adjacent pipe spacing of 150 mm. All air inlet pipes are connected to an air supply pipe via a T-joint, which is connected to an external compressed air source. A 30 mm gap is formed between the mounting block and the inner wall of the receiving hopper, allowing for a drainage channel between the filter screen and the inner wall.

[0055] Specifically, meat scraps and rinsing liquid generated during processing fall into the receiving hopper. The liquid passes through the filter screen to the bottom and is then discharged through the drain pipe. Solid debris is trapped by the filter screen and accumulates on its surface. Compressed air is continuously supplied to the receiving hopper through the air inlet pipe. The airflow rises along the gaps in the side walls to form a circulation, accelerating the dehydration of debris on the screen surface and preventing liquid splashing. When the debris accumulation thickness exceeds 5 mm, the operator can remove the first bolt to remove the filter screen for cleaning. During the cleaning process, the receiving hopper can still collect liquid through the gaps in the side walls. The dehydrated debris forms a loose structure due to the airflow, preventing it from hardening on the filter screen surface. The drain pipe is inclined at a 3° slope to ensure complete drainage without residue. The air supply pressure is maintained in the range of 0.2-0.3 MPa to ensure airflow strength while avoiding excessive energy consumption.

[0056] As a preferred embodiment, the solution of this application is specifically implemented as follows: The receiving hopper has mounting blocks around its inner wall, on which filter screens are mounted using bolts. A drain pipe is connected to the lower surface of the hopper, and multiple air inlet pipes are evenly spaced on both sides, each connected to an air supply pipe. Specifically, the receiving hopper is made of stainless steel, with eight mounting blocks evenly distributed around its inner wall. Each mounting block is L-shaped, with its horizontal portion welded to the inner wall and its vertical portion having threaded holes. The filter screen is woven from stainless steel wire with a mesh size of 1mm x 1mm. Through holes corresponding to the threaded holes on the mounting blocks are formed around the edges of the filter screen, which is then fixed to the mounting blocks using eight bolts. The drain pipe, a 50mm diameter PVC pipe, is connected to the center of the bottom of the receiving hopper. Five air inlet pipes, each 10mm diameter stainless steel, are installed on each side of the receiving hopper and welded to the side walls. The five air inlet pipes are evenly spaced, with a 100mm spacing between adjacent pipes. The air supply pipe is made of stainless steel with a diameter of 25mm and is connected to 10 air inlet pipes through a tee connector.

[0057] Through the above technical solution, this application achieves effective separation of wastewater and residue. The filter screen can intercept larger particles of residue, preventing them from clogging the drain pipe. The multiple air inlet pipes can deliver compressed air into the receiving hopper, accelerating water evaporation and simultaneously agitating the wastewater to prevent residue deposition. This design not only improves wastewater treatment efficiency but also facilitates cleaning and maintenance, effectively solving the problems of incomplete wastewater treatment and difficult residue removal in traditional equipment.

[0058] Please continue reading. Figure 1 As shown, in one embodiment of the present invention, the outer surface of the flattening roller 44 is coated with an anti-stick coating.

[0059] The anti-stick coating covers the outer surface of the flattening roller that contacts the meat slices. The coating material can be polytetrafluoroethylene (PTFE) or ceramic composite material, with a thickness controlled between 0.05 mm and 0.2 mm. The coating surface is polished to reduce the coefficient of friction and ensure no chemical residue remains upon contact with the meat slices. During the rotation of the flattening roller, the coating surface forms a physical isolation layer in the contact area with the meat slices, reducing adhesion caused by compression. The anti-stick coating, combined with the mesh structure of the conveyor belt, makes it easier for the meat slices to detach from the roller surface as they move with the conveyor belt after flattening. Furthermore, the hydrophobic properties of the coating prevent meat juices from seeping in, reducing the difficulty of subsequent cleaning by brushes and high-pressure nozzles.

[0060] Specifically, as the flattening rollers apply pressure to the meat slices, the anti-stick coating reduces the adhesion between the meat fibers and the roller surface by lowering the surface energy, allowing the flattened meat slices to detach completely from the roller surface and adhere to the conveyor belt. During the detachment process, any remaining meat scraps or juices on the coating surface form droplets due to their hydrophobic properties, which are then removed as they move to the brush area on the conveyor belt. The coating's abrasion resistance ensures that the anti-stick effect is maintained during continuous operation, preventing secondary adhesion of the meat slices due to coating wear. This structure improves meat slice flattening efficiency while reducing downtime for cleaning, ensuring the continuity of the processing flow and hygiene standards.

[0061] As a preferred embodiment, the solution of this application is specifically implemented as follows: an anti-stick coating is applied to the outer surface of the flattening roller. The anti-stick coating can be made of polytetrafluoroethylene (PTFE) material, and a uniform film is formed on the surface of the flattening roller through spraying or dip coating processes. The coating thickness is controlled within the range of 0.1-0.5 mm to ensure good anti-stick performance without affecting the flattening effect.

[0062] Through the above technical solution, this application prevents chicken meat from adhering to the surface of the flattening roller during the flattening process, reducing chicken meat loss and equipment cleaning frequency. The anti-stick coating makes the surface of the flattening roller smooth, reducing the friction between the chicken meat and the roller surface, and improving flattening quality and efficiency. At the same time, the coating has wear resistance, extending the service life of the flattening roller and reducing maintenance costs.

[0063] Please continue reading. Figure 1 and Figure 6 As shown, in one embodiment of the present invention, a limiting groove 55 is provided on the front surface of the receiving hopper 5, and a swing plate 57 is rotatably arranged in the limiting groove 55 via a rotating rod 56. The two ends of the rotating rod 56 are fixed by fixing nuts 58. A rubber scraper 59 that contacts the mesh conveyor belt 31 is provided on the rear surface of the swing plate 57.

[0064] The limiting groove is located on the front surface of the receiving hopper to accommodate the installation of the rotating rod. The rotating rod passes through the limiting groove and its axial displacement is limited by a fixing nut, ensuring the stability of the swing plate during rotation. The angle of the swing plate is adjusted by the rotating rod, ensuring that the rubber scraper on its rear surface remains in contact with the mesh conveyor belt. The rubber scraper is made of flexible material, which deforms upon contact with the conveyor belt to conform to its surface and thus scrape off the attached material. For example, the rotating rod can be a metal rod with a diameter of 10-15mm, the fixing nut can be an M8 standard part, and the hardness of the rubber scraper can be controlled within the Shore A range of 50-60 degrees.

[0065] Specifically, when the mesh conveyor belt is running, the rubber scraper continuously contacts the conveyor belt surface, removing residual meat scraps or moisture through friction. The oscillating plate adjusts its angle via a rotating rod, adapting the scraper to the conveyor belt's trajectory and preventing poor contact due to belt vibration. A locking nut, once tightened, restricts the axial movement of the rotating rod, ensuring the scraper's position is fixed. Residue scraped off falls directly into the receiving hopper, completing cleaning without stopping the machine. This structure achieves automatic cleaning while the conveyor belt is running continuously, preventing mesh clogging and bacterial growth, while reducing the frequency of manual intervention.

[0066] As a preferred embodiment, the solution of this application is specifically implemented as follows: A limiting groove is formed on the front surface of the receiving hopper. A swing plate is rotatably mounted within the limiting groove via a rotating rod. Both ends of the rotating rod are fixed with nuts. A rubber scraper, which contacts the mesh conveyor belt, is installed on the rear surface of the swing plate. Specifically, the limiting groove can be a rectangular groove with a depth of 20mm and a width of 30mm. The rotating rod can be made of stainless steel with a diameter of 10mm. The swing plate is made of polyethylene with a thickness of 5mm, and its width matches the width of the limiting groove. The rubber scraper is made of food-grade silicone with a thickness of 3mm, and its width matches the width of the mesh conveyor belt. The fixing nuts are M8 size.

[0067] Through the above technical solution, this application achieves effective cleaning of the surface of the mesh conveyor belt. The oscillating plate can automatically adjust its angle according to the movement of the conveyor belt, and the rubber scraper is in close contact with the conveyor belt, effectively scraping away residual meat scraps and water stains on the conveyor belt surface. This improves the cleaning effect of the equipment, reduces the risk of cross-contamination, avoids the tedious operation of manual cleaning, and enhances the continuous operation capability and production efficiency of the equipment.

[0068] Please continue reading. Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the driving component 6 includes a first rotating shaft 61, U-shaped plates 62 are provided on both the front and rear surfaces of the support frame 3, and U-shaped support frames 63 are provided at both the front and rear ends of the lower surface of the support frame 3. The first rotating shaft 61 is rotatably connected to the U-shaped support frame 63 via a third bearing. A first gear 64 is provided at both the left and right ends of the first rotating shaft 61. A rack 65 that meshes with the first gear 64 is provided at both the left and right ends of the inner side of the mesh conveyor belt 31. A second rotating shaft 66 is rotatably connected between the two vertical plates of the U-shaped plate 62 via a fourth bearing. A support block 67 is provided in the middle of the U-shaped plate 62. The second rotating shaft 66 passes through the support block 67 via a fifth bearing. A second gear 68 that meshes with the rack 65 is provided at both the left and right ends of the second rotating shaft 66. A second motor (not shown) for driving the first rotating shaft 61 is provided on the U-shaped support frame 63.

[0069] The first rotating shaft is mounted within a U-shaped support frame via a third bearing, and its left and right ends have first gears that mesh synchronously with the rack on the inner side of the conveyor belt. The second rotating shaft is supported at multiple points via fourth and fifth bearings, and its two ends have second gears that mesh with the rack. A support block is located in the middle of the U-shaped plate to enhance the bending strength of the second rotating shaft. The second motor drives the first rotating shaft to move the rack, while the second gears passively rotate with the rack.

[0070] Specifically, the first rotating shaft meshes with the rack on both sides via first gears, forming the main drive structure to ensure uniform force on both sides of the conveyor belt. The second rotating shaft meshes with the same rack via second gears at both ends, adding contact points to the main drive and preventing deformation or tooth slippage of the rack due to single-point force. Support blocks support the middle section of the second rotating shaft to prevent bending vibration of the long shaft during transmission. When the second motor drives the first rotating shaft to rotate, the first gear drives the rack and conveyor belt to move, while the second gear passively rotates with the rack, forming a double-meshing transmission. This structure distributes the transmission load through multi-point meshing, improving transmission smoothness. At the same time, the meshing motion of the gears and rack can scrape away residues in the rack gaps and conveyor belt mesh, reducing the frequency of manual cleaning.

[0071] As a preferred embodiment, the solution of this application is specifically implemented as follows: the driving component includes a first rotating shaft, U-shaped plates are provided on both the front and rear surfaces of the support frame, and U-shaped support frames are provided at both the front and rear ends of the lower surface of the support frame. The first rotating shaft is rotatably connected to the U-shaped support frame via a third bearing. A first gear is provided at both the left and right ends of the first rotating shaft. A rack that meshes with the first gear is provided at both the left and right ends of the inner side of the mesh conveyor belt. A second rotating shaft is rotatably arranged between the two vertical plates of the U-shaped plate via a fourth bearing. A support block is provided in the middle of the U-shaped plate. The second rotating shaft passes through the support block via a fifth bearing. A second gear that meshes with the rack is provided at both the left and right ends of the second rotating shaft. A second motor for driving the first rotating shaft is provided on the U-shaped support frame.

[0072] Specifically, the first rotating shaft can be made of stainless steel, with a diameter of 30mm and a length of 800mm. The U-shaped support frame can be made of aluminum alloy, with a height of 150mm and a width of 100mm. Both the first and second gears can be made of nylon, with 20 teeth and a module of 2. The rack can be made of stainless steel, with a length adapted to the width of the mesh conveyor belt. The second motor can be a 1.5kW servo motor, connected to the first rotating shaft via a coupling. The U-shaped plate can be made of stainless steel sheet with a thickness of 5mm. The support block can be made of nylon, with a height of 50mm. The third, fourth, and fifth bearings can all be deep groove ball bearings.

[0073] Through the above technical solution, this application achieves stable driving and precise control of the mesh conveyor belt. The adoption of a double-gear meshing structure enhances the stability and uniformity of the transmission, reducing conveyor belt deviation and vibration. The second rotating shaft further improves the support performance of the conveyor belt, preventing sagging and deformation during long-term operation. Simultaneously, the use of a second motor allows the conveying speed to be adjusted according to actual needs, adapting to different production rhythms. Furthermore, the design of the U-shaped support frame and U-shaped plate enhances the structural strength of the entire drive system, improving the durability and reliability of the equipment.

Figure 3 and Figure 7 As shown, in one embodiment of the present invention, a plurality of support sleeves 7 are equidistantly fitted on the left and right ends of the second rotating shaft 66 at the front end. Conical blocks 71 are fitted on both the left and right ends of the support sleeves 7. A plurality of rubber protrusions 72 are equidistantly arranged on the conical blocks 71 to facilitate the discharge of material from the mesh conveyor belt 31.

[0075] The support sleeves are equidistantly distributed at both ends of the second rotating shaft, and conical blocks are respectively fitted at both ends of the support sleeves. Rubber protrusions are fixed to the surface of the conical blocks in an equidistant arrangement. The conical outer surface of the conical block forms an inclined angle with the axis of the support sleeve. The rubber protrusions are made of elastic material and the protrusion height is controlled within the range of 3-5mm. The spacing between the support sleeves is set to 1.2-1.5 times the width of the conveyor belt mesh.

[0076] Specifically, when the second rotating shaft rotates, the support sleeves rotate synchronously with the shaft, causing the conical block and rubber protrusions to rotate around the shaft. The rubber protrusions contact the inner surface of the mesh conveyor belt, generating a scraping effect through elastic deformation, squeezing out meat scraps or moisture stuck in the mesh. The inclined surface of the conical block forms a guide slope during rotation, forcing residues to move along the conveyor belt's running direction. The equidistant distribution of the support sleeves ensures that the rubber protrusions form a continuous scraping area across the width of the conveyor belt, covering the entire mesh area. The height of the rubber protrusions is designed to penetrate deep into the mesh without damaging the conveyor belt surface, and the elastic material properties can adapt to minor deformations during conveyor belt operation. The ratio of the support sleeve spacing to the mesh width ensures that each mesh opening is acted upon by at least one rubber protrusion, avoiding cleaning blind spots.

[0077] As a preferred embodiment, the solution of this application is implemented as follows: Multiple support sleeves are equidistantly fitted at both ends of the second rotating shaft at the front end. Conical blocks are fitted at both ends of each support sleeve. Multiple rubber protrusions are equidistantly arranged on the conical blocks to assist in the discharge of material from the mesh conveyor belt. The support sleeves are made of stainless steel, with an inner diameter matching the outer diameter of the second rotating shaft, and are fixed to the second rotating shaft by an interference fit. The conical blocks are made of wear-resistant plastic, shaped like truncated cones, with the large end fitting against the outer wall of the support sleeve. The rubber protrusions are made of food-grade silicone material, hemispherical in shape, with a diameter of 5-10 mm and a height of 3-5 mm, and are evenly distributed on the surface of the conical blocks.

[0078] Through the above technical solution, this application achieves the auxiliary guiding function at the discharge end of the mesh conveyor belt. The combined structure of the support sleeve and the conical block increases the effective contact area of ​​the second rotating shaft, improving the support stability of the mesh conveyor belt. The rubber protrusion increases the contact friction with the chicken meat, preventing the chicken meat from slipping or sticking during conveying. The conical structure design allows the chicken meat to slide naturally down the slope, avoiding accumulation at the end of the conveyor belt. Therefore, the discharge effect of the chicken meat is improved, jamming and residue are reduced, and the continuous operation capability and production efficiency of the equipment are enhanced.

Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the upper end of the support plate 1 is provided with a plurality of threaded holes 8 at equal intervals, and the lower surface of the fixing frame 4 is provided with a mounting groove (not shown). The fixing frame 4 is sleeved on the support plate 1 through the mounting groove and connected and fixed by the second bolt 81.

[0080] The support plate has an array of threaded holes machined at equal intervals along its length at its upper end. The spacing of the threaded holes is set according to the height adjustment accuracy requirements of the flattening roller, for example, a set of holes is made every 50mm. The width of the mounting groove at the bottom of the fixed frame matches the thickness of the support plate, forming a sliding fit. Guide ribs can be set on the inner wall of the groove to improve assembly stability. The second bolt passes through the side wall of the fixed frame and is screwed into the threaded hole of the support plate. A washer can be added between the bolt head and the fixed frame to distribute the locking pressure.

[0081] Specifically, when installing the fixing frame, the operator selects the corresponding threaded hole according to the required height of the flattening roller, slides the mounting groove of the fixing frame along the length of the support plate to the target hole, and then inserts the second bolt to lock it in place. This structure achieves continuous position adjustment of the fixing frame along the length of the support plate through a multi-hole design. The evenly spaced threaded holes ensure adjustment accuracy, and the sliding fit between the mounting groove and the support plate prevents misalignment during frame installation. When it is necessary to adjust the working height of the flattening roller, simply loosen the second bolt and move the fixing frame along the support plate to the new hole position for re-fixing; there is no need to replace the support plate or the frame itself. The bolted connection method ensures structural rigidity while allowing for quick disassembly and maintenance. For example, the fixing frame can be removed during cleaning to remove residue from the surface of the support plate.

[0082] As a preferred embodiment, the solution of this application is implemented as follows: The upper end of the support plate is machined with twelve sets of equidistantly distributed M10 threaded holes, with a spacing of 50 mm between adjacent threaded holes. The fixing frame is cast from aluminum alloy, and its lower surface is machined with mounting grooves whose width matches the thickness of the support plate. During installation, the mounting grooves slide along the length of the support plate, allowing the fixing frame to cover two sets of symmetrical threaded holes. The support plate and the fixing frame are securely connected by passing M8 hexagonal bolts sequentially through the mounting holes on both sides of the fixing frame and screwing them into the selected threaded holes. When it is necessary to adjust the working height of the flattening roller, simply loosen the bolts and move the fixing frame longitudinally along the support plate to the target threaded hole position, then re-tighten to complete the height adjustment.

[0083] Through the above technical solution, this application achieves a modular transformation of the flattening roller height adjustment structure, solving the cumbersome operation problem of requiring overall disassembly and assembly of components when adjusting the flattening height in traditional equipment. The combination of a threaded hole array and a sliding mounting groove allows the fixed frame to achieve multi-level positioning adjustment within the longitudinal range of the support plate, effectively adapting to the processing needs of meat slices of different thicknesses. The use of bolted connections further ensures structural stability, preventing frame displacement due to vibration during equipment operation.

[0084] The electric motor, synchronous motor, and mesh conveyor belt used in this invention are all existing technologies, which are already well understood by those skilled in the art, and will not be described in detail here.

[0085] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be included in the scope of the present invention.
