Description

Technical Field

[0001] The present invention relates to the technical field of meat processing and manufacturing, and specifically relates to a self-cleaning belt conveyor. Background Art

[0002] On the intelligent meat cutting line, the belt conveyor plays an irreplaceable and important role. It has strong adaptability. Whether it is large pieces of raw meat or scattered meat pieces and meat slices after cutting, it can achieve continuous and stable transportation. At the same time, it can meet the long-distance transportation requirements, closely connect different processing areas, and ensure the smooth production process. Its high-speed operation characteristics greatly accelerate the production rhythm. Workers at each station can orderly complete tasks such as cutting, sorting, and packaging with the help of the belt conveyor, realizing multi-station collaborative operation, greatly increasing the output per unit time. The food-grade smooth material of the belt conveyor effectively reduces the risk of bacterial growth and contamination. The stable state during operation avoids collision and extrusion of the meat, comprehensively ensuring the hygiene and appearance quality of the product. It enables workers to get rid of the heavy burden of frequent material handling, focus on their own work, significantly reduce labor intensity, optimize the work experience, lay a solid foundation for the efficient and high-quality development of meat cutting production, and become an indispensable key equipment in the meat processing industry.

[0003] The Chinese patent with the publication number of CN112537618A discloses a cleaning device and a belt conveyor system for a belt conveyor, which realizes that when the driving motor operates, the driving motor drives the cleaning roller to rotate, and the cleaning brush on the cleaning roller can clean the conveyor belt under the first roller, so as to realize timely cleaning of the conveyor belt after discharging.

[0004] Existing belt conveyors generally come with a scraper to scrape off minced meat and bone chips. However, it is difficult to clean the grease attached to the belt surface by rigid components. It is necessary to manually spray a cleaning agent and use a brush or towel to clean the belt. After cleaning, manual rinsing is also required. In terms of cleaning effect, the rigid scraper is difficult to remove the grease on the belt surface. When manually using a brush or towel to clean, the cleaning liquid is difficult to be evenly mixed, and it cannot cover and penetrate into the gaps as comprehensively as the rotating and mixing cleaning liquid, resulting in many cleaning dead corners and serious grease residues, and the cleaning effect is not good. This not only affects the production quality, increases the risk of grease contaminating meat products, reduces the product quality and safety, but also if the manual cleaning is not timely or thorough, the grease will accelerate infiltration into the equipment interior, increase the running resistance, and exacerbate equipment wear. Manual cleaning requires frequent shutdowns and manual rinsing, consuming a lot of time and manpower, with low equipment utilization rate and frequent interruptions in the production process, making it difficult to optimize the production process and seriously affecting production efficiency.

[0005] Therefore, there is a need for a self-cleaning belt conveyor to solve the problems that it is difficult to remove various impurities adhering to the belt surface and it is impossible to automatically mix cleaning liquid to spray the belt. Summary of the Invention

[0006] In view of the problem that it is very difficult to clean the grease adhering to the belt by rigid components, it is necessary to manually spray the cleaning agent and use a brush or a towel to clean the belt, and it is also necessary to manually rinse the belt after cleaning, this application provides a self-cleaning belt conveyor.

[0018] (2)On the basis of the beneficial effect (1), the bone chips and meat scraps scraped off by the scraper are recycled, avoiding these impurities from being re - mixed into the boneless meat products during transportation. This helps to ensure the purity of the products, improve the quality and taste of the products, reduce the risk of consumers eating impurities during consumption, and when the bone chips and meat scraps get stuck between the shaving plate and the bottom plate, the bottom plate is extruded by the shaving plate, leaving them on the top of the bottom plate, and then the shaving plate continues to drive the remaining bone chips and meat scraps to move towards the side close to the door panel, avoiding damage to the device caused by jamming of the bottom plate, scraper and shaving plate.

[0019] (3)The self - cleaning belt conveyor of the present invention adopts this integrated cleaning and recycling system, which can synchronously carry out cleaning and recycling operations during the operation of the conveyor belt, without frequent shutdown for manual cleaning, greatly reducing the production interruption time caused by cleaning, improving the utilization rate of the equipment, ensuring the continuity of the production process, and thus improving the overall production efficiency. Combining the cleaning, recycling and other links with the operation of the conveyor belt forms an efficient integrated production process. This optimized process reduces manual intervention and additional operation steps, making the production process smoother and more orderly, and helping to improve the efficiency and coordination of the entire boneless meat production link.

The pressure roller 12, the support plate 14 and the clamping plate 15 are all located inside the belt 2. An uphill line 23 is fixed to the other ends of the two side plates 16 at the end of the bracket 11 away from the motor 3. A front weighing platform 24 is fixed to the end of the uphill line 23 away from the bracket 11. A rear weighing platform 26 is fixed to the other ends of the two side plates 16 at the other end of the bracket 11. A downhill plate 22 is fixed to the top of the bracket 11. A bone conveying line 21 is fixed to the other side of the downhill plate 22. Platforms 25 are fixed to the sides of the front weighing platform 24, the bracket 11 and the rear weighing platform 26 away from the motor 3.

[0025] In this embodiment, when the meat is weighed on the front weighing platform 24 and the weighing is completed, it is transported to the top of the belt 2 through the uphill line 23. The staff starts the motor 3, and the motor 3 drives the belt 2 to rotate through the transmission roller 13. The belt 2 drives the meat to move. The staff stands on the platform 25 to separate the meat. The pure meat is placed on the belt 2 for transportation, and the bones are moved to the bone conveyor line 21 through the downhill plate 22 for conveying. The pure meat is finally transported to the rear weighing platform 26 for weighing and then undergoes the next processing step.

[0026] Specifically, the mixing component 4 is assembled to mix the grease cleaner and water by utilizing 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, and the support 41 is fixed to one side of the two feeding cylinders 64 away from the bracket 11. The top of the support 41 is fixedly connected with a mixing barrel 42 through a connecting component. One side of the mixing barrel 42 is provided with a first feeding port 43 and a second feeding port 44. The first feeding port 43 is located above the second feeding port 44. The inner side of the mixing barrel 42 is rotatably connected with an auger frame 46. One end of the auger frame 46 away from the motor 3 and one end of the transmission roller 13 fixedly connected with the motor 3 away from the motor 3 are driven by two gears and a toothed belt. The bottom of one end of the mixing barrel 42 close to the motor 3 is connected through a conduit 45, and the other end of the conduit 45 is fixedly connected with a discharge pipe 5. The discharge pipe 5 is fixed to one side of the scraper 10 away from the baffle 61. One group of nozzles 51 is fixed to one side of the discharge pipe 5 close to the belt 2.

[0027] In this embodiment, before using this device, the staff should connect the grease cleaner to the first feeding port 43 through a diaphragm pump and a pipeline, and then connect the water source to the second feeding port 44 and the water pipe 9 through a water pump and a pipeline. When starting the motor 3, the diaphragm pump and the water pump are started simultaneously. The diaphragm pump pumps the grease cleaner into the mixing tank, and the water pump pumps the water flow into the inner side of the mixing tank and the inner side of the water pipe 9. The motor 3 drives the transmission roller 13 fixedly connected thereto to rotate, and the transmission roller 13 drives the auger frame 46 to rotate through two gears and a toothed belt. After the grease cleaner and the water flow enter the inner side of the mixing tank, the auger frame 46 mixes them. After the grease cleaner and the water are mixed evenly, the mixture enters the inner side of the discharge pipe 5 through the conduit 45 under the action of the diaphragm pump, the water pump, and the auger frame 46, and finally the mixture is sprayed onto the surface of the belt 2 by the nozzles 51.

[0028] At the same time, the auger frame 46 drives the reciprocating lead screw 65 to rotate through two gears and a toothed belt, and the reciprocating lead screw 65 drives one of the brush rollers 83 to rotate through two gears and a toothed belt.

[0029] Specifically, the scraping plate 10 is fixed to the inner side of the side plate 16 close to the motor 3, and the scraping plate 10 is located at the bottom of the driving roller 13. The shaving plate 7 is threadedly connected to the outside of the reciprocating lead screw 65. Push plates 71 are fixed to both sides of the shaving plate 7. One of the door plates 63 is in contact with the push plate 71. Oblique slots 72 are formed through both sides of the shaving plate 7, and the oblique slots 72 are located at the bottom of the push plate 71. The material removing member 6 is assembled to clean the grease and minced meat scraped off by the scraping plate 10 by using the power of the motor 3 to drive the belt 2 to rotate; the material removing member 6 includes a baffle 61. The baffle 61 is fixed to the side of the scraping plate 10 away from the bracket 11. The reciprocating lead screw 65 is rotatably connected through the inner side of the scraping plate 10. A partition 62 is fixed to the inner side of the scraping plate 10. Door plates 63 are rotatably connected to both sides inside the scraping plate 10. Feeding cylinders 64 are fixed to both sides of the scraping plate 10. A spring is fixed to the top of the bottom wall of the scraping plate 10, and the top of the spring is fixed to a bottom plate 66. A recycling box 67 is placed at the bottom of the two feeding cylinders 64.

[0030] In this embodiment, the reciprocating lead screw 65 drives the shaving plate 7 to reciprocate inside the scraping plate 10 through meshing. The shaving plate 7 scrapes off the minced meat and bone chips on the inner side of the scraping plate 10 and the top of the baffle 61. The oblique slots 72 are divided into a vertical section and a horizontal section. The vertical section removes the minced meat and bone chips on the surface of the scraping plate 10 and guides them to quickly fall onto the bottom plate 66, avoiding accumulation at the contact point between the belt 2 and the shaving plate 7. The horizontal section is mainly to remove the minced meat and debris on the top of the bottom plate 66 to avoid accumulation. As the minced meat and bone chips gradually accumulate on the surface of the scraping plate 10, when the bone chips and minced meat are stuck between the shaving plate 7 and the bottom plate 66, the bottom plate 66 is pushed by the shaving plate 7 to move towards the top of the bottom wall of the scraping plate 10, leaving them on the top of the bottom plate 66. Then the shaving plate 7 continues to drive the remaining bone chips and minced meat to move towards the side close to the door plate 63, avoiding jamming of the bottom plate 66, the scraping plate 10 and the shaving plate 7 and causing damage to the device. When the bone chips and minced meat or the push plate 71 come into contact with the door plate 63, the bone chips and minced meat or the push plate 71 push the door plate 63 to release the closure of the scraping plate 10. Then the shaving plate 7 pushes the bone chips and minced meat into the inner side of the feeding cylinder 64. When the reciprocating lead screw 65 drives the shaving plate 7 to move in the other direction, the minced meat and bone chips adhered to the bottom plate 66 and the scraping plate 10 are scraped again. Finally, the bone chips and minced meat flow into the recycling box 67 for collection.

[0031] Specifically, the brushing member 8 is assembled to brush the grease on the surface of the belt 2 by using the power of the motor 3 to drive the belt 2 to rotate in cooperation with the mixing member 4; the brushing member 8 includes two fixing plates 81, both of the two fixing plates 81 are fixed to the inner side of one end of the bracket 11 close to the motor 3, one side of the two fixing plates 81 is rotatably connected with a brush roller 83 and a pressing rod 82, there are five brush rollers 83 and five pressing rods 82, the pressing rod 82 is located above the brush roller 83, the brush roller 83 is located at the bottom of the belt 2, the belt 2 is located inside the pressing roller 12 and the brush roller 83, a small gear 84 is fixed to one end of each brush roller 83 away from the motor 3, and two adjacent small gears 84 are meshed, one end of one brush roller 83 away from the motor 3 is driven by a reciprocating lead screw 65 through two gears and a toothed belt, the waste water tank 86 is placed below the brush roller 83, the water pipe 9 is fixedly connected to one side of the scraper 10 close to the brush roller 83, and another group of nozzles 51 are fixedly connected to one side of the water pipe 9 close to the belt 2.

[0032] In this embodiment, one of the brush rollers 83 drives the other brush rollers 83 to rotate through the small gears 84. A cleaning hair with moderate hardness is fixed on the surface of the brush roller 83, so as to mix the grease and the mixture on the surface of the belt 2, so that they react, and then the grease is treated. Since two adjacent gears are meshed, the rotation directions of two adjacent brush rollers 83 are opposite, which improves the efficiency of the mixing reaction. The pressing rod 82 ensures full contact between the belt 2 and the brush roller 83. Finally, the water sprayed by the water pipe 9 and the nozzle rinses the surface of the belt 2, and the waste water enters the waste water tank 86 for collection under the action of gravity. The staff can use another diaphragm pump and pipeline to pump the waste water to the designated discharge location or the purification device for treatment.

[0033] Working principle: When the weighing of the meat is completed, it is transported to the top of the belt 2. The staff starts the motor 3, and the belt 2 drives the meat to move. The staff stands on the platform 25 to separate the meat. The pure meat is placed on the belt 2 for transportation, and the bones are moved to the bone conveyor line 21 through the downhill plate 22 for transportation. The pure meat is finally transported to the rear weighing table 26 for weighing, and then the next step of treatment is carried out. Before using this device, the staff should connect the grease cleaner to the first feed port 43, and then connect the water source to the second feed port 44 and the water pipe 9. When starting the motor 3, start the diaphragm pump and the water pump at the same time. The motor 3 drives the driving roller 13 fixedly connected thereto to rotate, and the driving roller 13 drives the auger frame 46 to rotate. The auger frame 46 mixes them. After the grease cleaner and water are evenly mixed, the mixture enters the inner side 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 lead screw 65 to rotate through two gears and a toothed belt. The reciprocating lead screw 65 drives one of the brush rollers 83 to rotate through two gears and a toothed belt. The reciprocating lead screw 65 drives the shaving plate 7 to move back and forth inside the scraper 10. The shaving plate 7 scrapes off the minced meat and bone chips on the inner side of the scraper 10 and the top of the baffle 61. When the bone chips and minced meat or the push plate 71 contact the door plate 63, the bone chips and minced meat or the push plate 71 push the door plate 63 to release the sealing of the scraper 10. Then the shaving plate 7 pushes the bone chips and minced meat into the inner side of the blanking cylinder 64. When the reciprocating lead screw 65 drives the shaving plate 7 to move in the other direction, it scrapes off the minced meat and bone chips adhered to the bottom plate 66 and the scraper 10 again. Finally, the bone chips and minced meat flow into the recovery box 67 for collection; One of the brush rollers 83 drives the remaining brush rollers 83 to rotate through a small gear 84, thereby brushing the grease on the surface of the belt 2, mixing the grease and the mixture, making them react, and then treating the grease. The pressure rod 82 ensures full contact between the belt 2 and the brush rollers 83. Finally, the water sprayed by the water pipe 9 and the nozzle rinses the surface of the belt 2. The wastewater enters the wastewater tank 86 for collection under the action of gravity. The staff can use another diaphragm pump and pipeline to pump the wastewater to the designated discharge location or purification device for treatment.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
