Description

Technical Field

[0001] This invention relates to the field of meat processing and manufacturing technology, specifically to a self-cleaning belt conveyor. Background Technology

[0002] In intelligent meat processing lines, belt conveyors play an irreplaceable and crucial role. They possess strong adaptability, enabling continuous and stable transport of both large chunks of raw meat and smaller, pre-cut pieces. They also meet long-distance transport needs, seamlessly connecting different processing areas to ensure smooth production. Their high-speed operation significantly accelerates the production pace. Workers at each station can efficiently complete tasks such as cutting, sorting, and packaging, enabling multi-station collaborative operations and greatly increasing output per unit time. The food-grade smooth material of the belt conveyor effectively reduces bacterial growth and contamination risks. Its stable operation avoids collisions and compression of the meat, comprehensively ensuring product hygiene and appearance quality. It frees workers from the burden of frequent material handling, allowing them to focus on their core tasks, significantly reducing labor intensity and optimizing the work experience. This lays a solid foundation for efficient and high-quality meat processing production, making it an indispensable key piece of equipment in the meat processing industry.

[0003] Chinese patent CN112537618A discloses a cleaning device and belt conveyor system for belt conveyors. When the drive motor is running, the drive motor drives the cleaning roller to rotate, and the cleaning brush on the cleaning roller can clean the conveyor belt under the first roller, thereby achieving timely cleaning of the conveyor belt after unloading.

[0004] Existing belt conveyors typically come with a scraper to remove meat scraps and bone fragments. However, grease from meat adheres to the belt surface and is difficult to remove using rigid components. This necessitates manual cleaning with sprayed cleaning agents and brushes or towels. After cleaning, manual rinsing is also required. In terms of cleaning effectiveness, rigid scrapers are insufficient to remove grease from the belt surface. When using brushes or towels manually, the cleaning solution is difficult to mix evenly and cannot fully cover and penetrate crevices like a rotating cleaning solution. This results in many cleaning dead spots, serious grease residue, and poor cleaning results. This not only affects production quality and increases the risk of grease contamination of meat products, reducing product quality and safety, but also allows grease to penetrate the equipment more quickly if manual cleaning is not timely or thorough. This increases operating resistance and accelerates equipment wear. Manual cleaning requires frequent machine shutdowns and manual rinsing, consuming a lot of time and manpower. Equipment utilization is low, production processes are frequently interrupted, and it is difficult to optimize the production process, seriously affecting production efficiency.

[0005] Therefore, a self-cleaning belt conveyor is needed to solve the problems of difficulty in removing various impurities adhering to the belt surface and the inability to automatically mix cleaning fluid and spray it onto the belt. Summary of the Invention

[0006] To address the problem that it is difficult to clean grease adhering to rigid belt components, requiring manual spraying of cleaning agents and cleaning with brushes or towels, followed by manual rinsing, this application provides a self-cleaning belt conveyor.

[0007] The technical solution of the present invention is as follows: a self-cleaning belt conveyor, comprising a support frame, a pressure roller slidably connected to the inner side of the support frame, two side plates fixed at both ends of the support frame, a transmission roller rotatably connected to the inner side of the two side plates at the same end of the support frame, a belt fitted on the outer side of the two transmission rollers, a motor fixed to one end of one of the transmission rollers, a scraper provided at the bottom of the transmission roller fixedly connected to the motor, a shaving plate provided on the inner side of the scraper, a material removal component provided on one side of the scraper, a mixing component provided on the side of the material removal component away from the support frame, a discharge pipe connected to one end of the mixing component, a brushing component provided on the side of the scraper close to the support frame, and a water pipe provided on the side of the brushing component close to the scraper; the material removal component is configured to clean the grease and meat scraps scraped off by the scraper by using the power of the motor driving the belt to rotate; the mixing component is configured to mix the grease cleaner and water by using the power of the motor driving the belt to rotate, and then spray it onto the belt surface; the brushing component is configured to brush the grease on the belt surface by using the power of the motor driving the belt to rotate in conjunction with the mixing component.

[0008] Furthermore, a clamping plate is fixed to the inner side of the top of the bracket, and a support plate is fixed to the inner side of the clamping plate. The pressure roller, the support plate, and the clamping plate are all located inside the belt.

[0009] Furthermore, the scraper is fixed to the inside of the side plate near the motor, and the scraper is located at the bottom of the drive roller.

[0010] Furthermore, the material removal components include a baffle plate, which is fixed to the side of the scraper away from the support. A reciprocating screw is rotatably connected through the inner side of the scraper. A partition plate is fixed to the inner side of the scraper. Door panels are rotatably connected to the inner sides of both sides of the scraper. Feed cylinders are fixed to both sides of the scraper. A spring is fixed to the top of the bottom wall of the scraper. A bottom plate is fixed to the top of the spring. A recycling box is placed at the bottom of the two feed cylinders.

[0011] Furthermore, the shaving plate is threaded to the outside of the reciprocating screw, and push plates are fixed on both sides of the shaving plate. One of the door panels is attached to the push plate, and inclined grooves are opened through both sides of the shaving plate, with the inclined grooves located at the bottom of the push plate.

[0012] Furthermore, the mixing component includes a support, which is fixed to the side of the two feeding cylinders away from the bracket. A mixing tank is fixed to the top of the support through a connecting component. A feeding port 1 and a feeding port 2 are opened on one side of the mixing tank. Feeding port 1 is located above feeding port 2. An auger is rotatably connected to the inside of the mixing tank. The end of the auger away from the motor and the end of the transmission roller fixedly connected to the motor away from the motor are driven by two gears and a toothed belt. A guide tube is connected through the bottom of the end of the mixing tank near the motor. The other end of the guide tube is fixedly connected to the discharge pipe.

[0013] Furthermore, the discharge pipe is fixed to the side of the scraper away from the baffle, and one set of nozzles is fixed to the side of the discharge pipe near the belt.

[0014] Furthermore, the brushing component includes two fixing plates, both of which are fixed to the inner side of the bracket near the motor. A brush roller and a pressure rod are rotatably connected to one side of the two fixing plates. There are five brush rollers and five pressure rods. The pressure rod is located above the brush roller, and the brush roller is located at the bottom of the belt. The belt is located inside the pressure roller and the brush roller. A small gear is fixed to the end of each brush roller away from the motor, and two adjacent small gears mesh. A reciprocating screw at the end of one brush roller away from the motor is driven by two gears and a toothed belt. The wastewater tank is placed below the brush roller.

[0015] Furthermore, a water pipe is fixedly connected to the side of the scraper near the brush roller, and another set of nozzles is fixedly connected to the side of the water pipe near the belt.

[0016] Furthermore, an uphill line is fixed to the other end of the two side plates located at the end of the support away from the motor, and a front weighing platform is fixed to the end of the uphill line away from the support. A rear weighing platform is fixed to the other end of the two side plates located at the other end of the support. A downhill plate is fixed to the top of the support, and a bone conveying line is fixed to the other side of the downhill plate. A platform is fixed to the side of the front weighing platform, the support, and the rear weighing platform away from the motor.

[0017] The beneficial effects of this invention are as follows:

[0018] (1) The self-cleaning belt conveyor described in this invention can scrape off and recycle meat and bone fragments from the belt surface by scraper and shaving plate during conveying operation. At the same time, it can mix grease cleaner and water and spray it onto the belt surface, then clean it by bidirectional rotation of brush roller, and finally rinse it with water pipe to complete the cleaning of all impurities on the belt surface. Compared with the prior art, the cleaning agent and water can be mixed by the force of the conveyor belt rotation, so that the two can be fully blended to form a uniform cleaning liquid. When this uniform cleaning liquid is sprayed onto the conveyor belt, it can cover the belt surface more comprehensively and effectively, greatly improving the efficiency of the cleaning liquid and helping to remove various stubborn grease and stains. The bidirectional rotating brush roller can brush the belt surface from different directions. This multi-angle brushing method can penetrate into the gaps and textures of the belt to thoroughly remove grease and dirt, avoiding the cleaning dead corners that may exist in unidirectional brushing, making the belt surface cleaner more thorough, reducing grease residue, and thus maintaining the cleanliness and hygiene of the conveyor belt.

[0019] (2) Based on the beneficial effect (1), the bone scraps and meat scraps scraped off by the scraper are recycled, which avoids these impurities from being mixed back into the deboned meat products during transportation. This helps to ensure the purity of the product, improve the quality and taste of the product, and reduce the risk of consumers eating impurities during consumption. When bone scraps and meat scraps are stuck between the scraper and the bottom plate, the bottom plate is squeezed by the scraper and leaves them on the top of the bottom plate. Then the scraper continues to move the remaining bone scraps and meat scraps to the side closer to the door panel, avoiding damage to the device caused by the bottom plate, scraper and scraper jamming.

[0020] (3) The self-cleaning belt conveyor described in this invention employs an integrated cleaning and recycling system that enables simultaneous cleaning and recycling operations during conveyor belt operation. This eliminates the need for frequent machine shutdowns for manual cleaning, significantly reducing production interruptions caused by cleaning, improving equipment utilization, ensuring production continuity, and thus enhancing overall production efficiency. By combining cleaning and recycling with conveyor belt operation, a highly efficient integrated production process is formed. This optimized process reduces manual intervention and additional operating steps, making the production process smoother and more orderly, and contributing to improved efficiency and coordination throughout the entire deboned meat production process.

[0037] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0038] Example: Figure 12-14 As shown, the intelligent dividing line includes a pre-deboning weighing area 31, a deboning area 32, a hanging sorting and weighing station 33, a trimming area 34, and a packaging area 35. In this embodiment, the deboning area 32 is used as an example for demonstration.

[0039] like Figures 1-11As shown, a self-cleaning belt conveyor includes a support frame 11. A pressure roller 12 is slidably connected to the inner side of the support frame 11. Two side plates 16 are fixed at both ends of the support frame 11. A drive roller 13 is rotatably connected to the inner side of the two side plates 16 located at the same end of the support frame 11. A belt 2 is fitted on the outer side of the two drive rollers 13. A motor 3 is fixed to one end of one of the drive rollers 13. A scraper 10 is provided at the bottom of the drive roller 13, and a shaving plate 7 is provided on the inner side of the scraper 10. A material removal component 6 is provided on one side of the scraper 10. A mixing component 4 is provided on the side of the material removal component 6 away from the support frame 11. One end of the mixing component 4 is connected to a discharge pipe 5. A brushing component 8 is provided on the side of the scraper 10 near the support frame 11. A water pipe 9 is provided on the side of the brush 8 near the scraper 10. A clamping plate 15 is fixed on the inner side of the top of the bracket 11. A support plate 14 is fixed on the inner side of the clamping plate 15. The pressure roller 12, the support plate 14 and the clamping plate 15 are all located on the inner side of the belt 2. An uphill line 23 is fixed on the other end of the two side plates 16 located at the end of the bracket 11 away from the motor 3. A front weighing platform 24 is fixed on the end of the uphill line 23 away from the bracket 11. A rear weighing platform 26 is fixed on the other end of the two side plates 16 located at the other end of the bracket 11. A downhill plate 22 is fixed on the top of the bracket 11. A bone conveying line 21 is fixed on the other side of the downhill plate 22. A platform 25 is fixed on the side of the front weighing platform 24, the bracket 11 and the rear weighing platform 26 away from the motor 3.

[0040] In this embodiment, when the meat is weighed on the front weighing platform 24, after weighing, it is transported to the top of the conveyor belt 2 via the uphill line 23. The operator starts the motor 3, which drives the conveyor belt 2 to rotate via the transmission roller 13. The conveyor belt 2 moves the meat. The operator stands on the platform 25 to separate the meat. The pure meat is placed on the conveyor belt 2 for transport, and the bones are moved to the bone conveyor line 21 via the downhill plate 22 for transport. The pure meat is finally transported to the rear weighing platform 26 for weighing, and then proceeds to the next step of processing.

[0041] Specifically, the mixing component 4 is assembled to mix grease cleaner and water by using the power of the motor 3 to drive the belt 2 to rotate, and then spray it onto the surface of the belt 2. The mixing component 4 includes a support 41, which is fixed to the side of the two feed cylinders 64 away from the bracket 11. The top of the support 41 is fixed to the mixing tank 42 by a connecting component. The mixing tank 42 has a feed inlet 1 43 and a feed inlet 2 44 on one side. The feed inlet 1 43 is located above the feed inlet 2 44. The inner side of the mixing tank 42 is rotatably connected to an auger frame 46. The end of the auger frame 46 away from the motor 3 and the end of the transmission roller 13 fixedly connected to the motor 3 away from the motor 3 are driven by two gears and a toothed belt. The bottom of the mixing tank 42 near the motor 3 is connected to a guide tube 45. The other end of the guide tube 45 is fixedly connected to the discharge pipe 5. The discharge pipe 5 is fixed to the side of the scraper 10 away from the baffle 61. One set of nozzles 51 is fixed to the side of the discharge pipe 5 near the belt 2.

[0042] In this embodiment, before using this device, the operator should connect the grease cleaner to the inlet 43 via a diaphragm pump and pipeline, and then connect the water source to the inlet 44 and water pipe 9 via a water pump and pipeline. Simultaneously, the diaphragm pump and water pump are started when the motor 3 is started. The diaphragm pump pumps the grease cleaner into the mixing tank, and the water pump pumps water into the inside of the mixing tank and the inside of the water pipe 9. The motor 3 drives the transmission roller 13, which is fixedly connected to it, to rotate. The transmission roller 13 drives the auger frame 46 to rotate through two gears and a toothed belt. After the grease cleaner and water flow into the inside of the mixing tank, the auger frame 46 mixes them. After the grease cleaner and water are mixed evenly, the mixture enters the inside of the discharge pipe 5 through the conduit 45 under the action of the diaphragm pump, water pump, and auger frame 46. Finally, the mixture is sprayed onto the surface of the belt 2 by the nozzle 51.

[0043] At the same time, the auger frame 46 drives the reciprocating screw 65 to rotate through two gears and a toothed belt, and the reciprocating screw 65 drives one of the brush rollers 83 to rotate through two gears and a toothed belt.

[0044] Specifically, scraper 10 is fixed to the inner side of side plate 16 near motor 3, and scraper 10 is located at the bottom of transmission roller 13. Shaving plate 7 is threaded to the outer side of reciprocating screw 65. Push plates 71 are fixed on both sides of shaving plate 7, and one door plate 63 is attached to push plate 71. Inclined grooves 72 are opened through both sides of shaving plate 7, and the inclined grooves 72 are located at the bottom of push plate 71. The scraper 6 is assembled to scrape off grease and other debris by using the power of motor 3 to drive belt 2 to rotate. The scrap meat is cleaned; the material removal component 6 includes a baffle 61, which is fixed to the side of the scraper 10 away from the support 11. A reciprocating screw 65 is rotatably connected through the inner side of the scraper 10. A partition 62 is fixed to the inner side of the scraper 10. Door panels 63 are rotatably connected to the inner sides of both sides of the scraper 10. Feed cylinders 64 are fixed to both sides of the scraper 10. A spring is fixed to the top of the bottom wall of the scraper 10. A bottom plate 66 is fixed to the top of the spring. A recycling box 67 is placed at the bottom of the two feed cylinders 64.

[0045] In this embodiment, the reciprocating screw 65 drives the shaving plate 7 to reciprocate inside the scraper 10 through meshing. The shaving plate 7 scrapes away meat scraps and bone fragments from the inside of the scraper 10 and the top of the baffle 61. The inclined groove 72 is divided into a vertical section and a horizontal section. The vertical section removes meat scraps and bone fragments from the surface of the scraper 10 while guiding them to fall quickly to the bottom plate 66, avoiding accumulation at the contact point between the belt 2 and the shaving plate 7. The horizontal section is mainly for removing meat scraps and debris from the top of the bottom plate 66 to prevent accumulation. As meat scraps and bone fragments gradually accumulate on the surface of the scraper 10, when bone fragments and meat scraps are stuck between the shaving plate 7 and the bottom plate 66, the bottom plate 66 is squeezed towards the bottom plate 66 by the action of the shaving plate 7. The scraper 10 moves to the top of the bottom wall, leaving it on top of the bottom plate 66. Then the shaving plate 7 continues to move the remaining bone and meat scraps towards the side closer to the door plate 63, preventing the bottom plate 66, scraper 10, and shaving plate 7 from jamming and causing damage to the device. When the bone and meat scraps or the push plate 71 come into contact with the door plate 63, the bone and meat scraps or the push plate 71 push the door plate 63 to release the seal on the scraper 10. Then the shaving plate 7 pushes the bone and meat scraps into the inside of the feed cylinder 64. When the reciprocating screw 65 drives the shaving plate 7 to move in another direction, it scrapes off the meat and bone scraps stuck to the bottom plate 66 and scraper 10 again. Finally, the bone and meat scraps flow into the recycling box 67 for collection.

[0046] Specifically, the brushing component 8 is assembled to brush away grease from the surface of the belt 2 by means of a power-driven mixing component 4 that rotates the belt 2 using a motor 3. The brushing component 8 includes two fixing plates 81, both of which are fixed to the inner side of the bracket 11 near the motor 3. A brush roller 83 and a pressure rod 82 are rotatably connected to one side of the two fixing plates 81. Five brush rollers 83 and five pressure rods 82 are provided. The pressure rods 82 are located above the brush rollers 83, and the brush rollers 83 are located on the belt. At the bottom, belt 2 is located inside pressure roller 12 and brush roller 83. Each brush roller 83 has a pinion 84 fixed at the end away from motor 3, and two adjacent pinions 84 mesh. One brush roller 83 has a reciprocating screw 65 at the end away from motor 3 driven by two gears and a toothed belt. Wastewater tank 86 is placed below brush roller 83. Water pipe 9 is fixedly connected to the scraper 10 on the side near brush roller 83. Another set of nozzles 51 is fixedly connected to the side of water pipe 9 near belt 2.

[0047] In this embodiment, one of the brush rollers 83 drives the other brush rollers 83 to rotate via a pinion 84. The surface of the brush roller 83 is fixed with bristles of moderate hardness for cleaning, which mixes the grease and mixture on the surface of the belt 2, causing it to react and thus treating the grease. Since the two adjacent gears mesh, the adjacent brush rollers 83 rotate in opposite directions, which improves the efficiency of the mixing reaction. The pressure rod 82 ensures that the belt 2 and the brush roller 83 are in full contact.

[0048] Finally, the water sprayed from the water pipe 9 and the nozzle washes the surface of the belt 2. The wastewater enters the wastewater tank 86 for collection under gravity. The staff can use another diaphragm pump and pipeline to pump the wastewater to a designated discharge point or purification device for treatment.

[0049] Working principle: After the meat is weighed, it is transported to the top of the conveyor belt 2. The staff starts the motor 3, and the conveyor belt 2 moves the meat. The staff stands on the platform 25 to separate the meat. The pure meat is placed on the conveyor belt 2 for transportation. The bones are moved through the downhill plate 22 to the bone conveyor line 21 for transportation. The pure meat is finally transported to the rear weighing platform 26 for weighing, and then proceeds to the next step of processing.

[0050] Before using this device, the operator should connect the grease cleaner to inlet 43, and then connect the water source to inlet 44 and water pipe 9. Simultaneously, start the diaphragm pump and water pump while starting the motor 3. The motor 3 drives the transmission roller 13, which is fixedly connected to it, to rotate. The transmission roller 13 drives the auger frame 46 to rotate, and the auger frame 46 mixes the grease cleaner and water. After the grease cleaner and water are evenly mixed, the mixture enters the inside of the discharge pipe 5 through the conduit 45. Finally, the nozzle 51 sprays the mixture onto the surface of the belt 2. At the same time, the auger frame 46 drives the reciprocating screw 65 to rotate through two gears and a toothed belt. The reciprocating screw 65 rotates through two gears... The toothed belt drives one of the brush rollers 83 to rotate, and the reciprocating screw 65 drives the shaving plate 7 to reciprocate inside the scraper 10. The shaving plate 7 scrapes away the meat and bone fragments on the inside of the scraper 10 and the top of the baffle 61. When the bone and meat fragments or the push plate 71 come into contact with the door panel 63, the bone and meat fragments or the push plate 71 push the door panel 63 to release the seal on the scraper 10. Then the shaving plate 7 pushes the bone and meat fragments into the inside of the feed cylinder 64. When the reciprocating screw 65 drives the shaving plate 7 to move in another direction, it scrapes away the meat and bone fragments stuck to the bottom plate 66 and the scraper 10 again. Finally, the bone and meat fragments flow into the recycling box 67 for collection.

[0051] One of the brush rollers 83 drives the other brush rollers 83 to rotate via a pinion 84, thereby brushing the grease on the surface of the belt 2 and mixing the grease and the mixture to react and treat the grease. The pressure bar 82 ensures that the belt 2 is in full contact with the brush roller 83. Finally, water sprayed from the water pipe 9 and the nozzle washes the surface of the belt 2. The wastewater enters the wastewater tank 86 for collection under gravity. The staff can use another diaphragm pump and pipeline to pump the wastewater to a designated discharge point or purification device for treatment.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
