Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, and more specifically, to a raw material transportation device for food processing with an anti-drop function. Background Technology

[0002] In the food processing and production process, the transportation of raw materials is a key link connecting various processes. At present, the food processing industry generally uses belt conveyors to transfer raw materials between various workstations. With the continuous improvement of food safety standards, stricter basic requirements and management guidelines have been put forward for facilities and equipment, hygiene management and transportation of food raw materials in the food production process. How to ensure that raw materials remain stable during transportation and avoid falling from the edge or gap of the conveyor belt has become a technical problem that urgently needs to be solved in the design of food processing equipment.

[0003] Currently, the industry has proposed several technical solutions to address the issue of preventing raw material transport devices from falling off. These include installing fixed baffles on both sides of the conveyor belt, adding adjustable movable plates to both sides, and using limiting grooves or anti-slip textures on the conveyor belt surface to increase the stability of raw material transport. However, the adjustment process of existing anti-fall devices usually requires machine shutdown, and the adjustment accuracy depends on manual experience, making it difficult to quickly respond to changes in the size of different batches of raw materials. Furthermore, there are issues with hygiene and cleaning dead zones and inconvenient maintenance. Food processing equipment has strict requirements for cleanliness and hygiene, and gaps and welding dead zones in the transport device are prone to leaving material debris, becoming a hidden danger for microbial growth. Existing anti-fall structures are often fixedly connected to the conveyor belt frame, making disassembly and cleaning difficult and causing contamination of food raw materials. Summary of the Invention

[0004] This invention proposes a raw material transport device for food processing with an anti-drop function, which solves the problems of slow adjustment speed of existing anti-drop devices and easy growth of microorganisms in the gap between the baffle and the conveyor belt.

[0005] The technical solution of the present invention is as follows: A food processing raw material conveying device with anti-drop function includes a frame, two drive rollers rotatably mounted on the frame, and a conveyor belt wrapped around the two drive rollers, and further includes: Side baffles are provided, two of which are respectively located on both sides above the conveyor belt. The side baffles are movably mounted on the frame. The bottom end of the side baffles is attached to the surface of the conveyor belt to block and limit the conveyed material. The side baffles and the conveyor belt rotate synchronously. Support rollers, which are rotatably mounted on the frame, and multiple support rollers are provided to support the bottom of the working area of ​​the conveyor belt; A cleaning mechanism is provided for cleaning the surfaces of the conveyor belt and the side baffle belt. The cleaning mechanism includes a conveying cleaning component and a baffle cleaning component. The cleaning delivery component includes: A spray pipe is installed on the frame and located below the conveyor belt. The spray pipe has several spray holes for spraying water onto the surface of the conveyor belt. A wiping roller is mounted on the frame and contacts the bottom end of the conveyor belt. The wiping roller is located behind the spray pipe along the direction of movement of the conveyor belt. The material-blocking and cleaning component includes: A cleaning roller is disposed on the outside of the side baffle belt, and a brush is disposed on the outside of the cleaning roller for cleaning the surface of the side baffle belt.

[0006] To ensure the drying effect of the wiping rollers on the conveyor belt, multiple wiping rollers are provided. A conversion frame is rotatably mounted on the frame, and the wiping rollers are rotatably mounted on the conversion frame to replace the wiping rollers that are in contact with the conveyor belt.

[0007] To further ensure the drying effect of the wiping roller on the conveyor belt, a drying box is installed on the frame. The drying box is connected to a fan and has a heater inside. The drying box has an opening for the wiping roller to enter and exit and for the conversion frame to rotate.

[0008] To further improve the drying effect on the conveyor belt, the drying chamber is connected to a drying pipe, which has an air outlet facing the lower side of the conveyor belt.

[0009] To collect material debris after cleaning, a debris collection bin is installed on the frame, located below the conveyor belt. A debris baffle is provided on the frame, and a cleaning roller is located inside the debris baffle to block the debris from falling into the debris collection bin.

[0010] To achieve the rotational movement of the side baffle belt, two adjusting plates are movably mounted on the frame, each corresponding to a side baffle belt. Two rotating rollers are rotatably mounted on each adjusting plate, and the side baffle belt wraps around these rollers. A sprocket is coaxially fixed to one of the rotating rollers on one side, and a transmission gear is coaxially fixed to the other rotating roller on the other side. A second sprocket is rotatably mounted on the adjusting plate. The first and second sprockets are connected by a chain drive, and a second transmission gear is coaxially fixed to the second sprocket, meshing with the first transmission gear. A tensioning assembly is provided on the frame to tension the chain to accommodate the movement of the side baffle belt. The tensioning assembly includes: A movable plate, which is movably mounted on the frame; The tensioning wheel is rotatably mounted on the tensioning block, and the tensioning wheel is in contact with the chain. The movable plate is connected to the tensioning block via a telescopic rod and a compression spring.

[0011] To enable the movement of the side baffle, a bidirectional screw is rotatably mounted on the frame, and two adjusting plates are symmetrically arranged outside the bidirectional screw and threadedly connected to the two threaded sections of the bidirectional screw.

[0012] The working principle and beneficial effects of this invention are as follows: 1. In this invention, by setting movable side baffles on both sides above the conveyor belt and making the side baffles rotate synchronously with the conveyor belt, dynamic and flexible blocking and limiting of the conveyed material is achieved. Compared with traditional fixed baffles, the side baffles can quickly adjust their position according to the size of the raw material, and their bottom is in contact with the surface of the conveyor belt, avoiding the risk of material falling from the edge. At the same time, since the side baffles move with the conveyor belt, the relative friction between the material and the baffle structure is reduced, reducing the possibility of material damage and blockage.

[0013] 2. In this invention, by setting up cleaning mechanisms such as spray pipes, wiping rollers, and sweeping rollers, the surfaces of the conveyor belt and the side baffle belt can be automatically cleaned. The spray pipes spray and clean the conveyor belt, the wiping rollers absorb or wipe away moisture in time, and the sweeping rollers sweep the surface of the side baffle belt with brushes, effectively removing residual material debris and stains. This reduces the problem of material accumulation and microbial growth in the gap between the baffle and the conveyor belt in traditional devices, and significantly improves the hygiene and safety of the food processing process.

[0014] 3. In this invention, by setting up a drying box, a fan, a heater, and a drying pipe, the wiping roller and the conveyor belt are dried, which further ensures the dryness and cleanliness of the conveyor belt surface and reduces the adhesion of food raw materials on the conveyor belt. By setting up a debris collection bin and a debris baffle, the material debris swept off is collected in a concentrated manner, avoiding secondary pollution. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 2 As shown, this embodiment proposes a raw material transport device for food processing with anti-drop function, including a frame 1, two drive rollers 2 rotatably mounted on the frame 1, and a conveyor belt 3 wrapped around the two drive rollers 2. The frame 1 is equipped with a drive motor 4 for driving the drive rollers 2 to rotate, and also includes a side baffle belt 5, a support roller 15, and a cleaning mechanism.

[0020] like Figures 1 to 4 As shown, two side baffles 5 are provided and located on both sides above the conveyor belt 3. The side baffles 5 are movably mounted on the frame 1. The bottom end of the side baffles 5 is in contact with the surface of the conveyor belt 3 to block and limit the conveyed material. The side baffles 5 and the conveyor belt 3 rotate synchronously. Figure 4 , Figure 5 and Figure 11 As shown, to achieve the rotational movement of the side baffle belt 5, two adjusting plates 6 are movably mounted on the frame 1. Each adjusting plate 6 corresponds to one side baffle belt 5. Two rotating rollers 7 are rotatably mounted on the adjusting plates 6. The side baffle belt 5 wraps around the two rotating rollers 7. A sprocket 8 is coaxially fixed on one of the rotating rollers 7 on one side, and a transmission gear 1 is coaxially fixed on the other rotating roller 7 on the other side. A second sprocket 10 is rotatably mounted on the adjusting plate 6. The first sprocket 8 and the second sprocket 10 are connected by a chain drive. A second transmission gear 11 is coaxially fixed on the second sprocket 10, and the second transmission gear 11 meshes with the first transmission gear 9. A motor 12 is mounted on one of the adjusting plates 6, and one of the rotating rollers 7 is fixedly mounted at the output end of the motor 12. A tensioning assembly is provided on the frame 1 for tensioning the chain to accommodate the movement of the side baffle belt 5, such as... Figure 5As shown, the tensioning assembly includes a movable plate 101 and a tensioning wheel 102. The movable plate 101 is movably mounted on the frame 1. An electric cylinder 103 is mounted on the frame 1. The movable plate 101 is fixedly mounted on the output end of the electric cylinder 103. The movable plate 101 is connected to a tensioning block 104 via a telescopic rod and a compression spring. The tensioning wheel 102 is rotatably mounted on the tensioning block 104 and contacts the chain. A bidirectional screw 13 is rotatably mounted on the frame 1. A motor 14 is mounted on the frame 1. Rod 13 is fixedly mounted at the output end of motor 14. Two adjusting plates 6 are symmetrically arranged outside the bidirectional screw 13 and threadedly connected to the two threaded sections of the bidirectional screw 13. Motor 14 can drive the bidirectional screw 13 to rotate, thereby adjusting the distance between the two adjusting plates 6, causing the two side baffles 5 to move closer or further apart to accommodate materials of different sizes. Motor 12 can drive the rotating roller 7 connected to it to rotate, and under the transmission action of the chain, the sprocket 8 and the sprocket... The second sprocket 10 rotates synchronously, driving the transmission gear 11 to rotate, which in turn drives the transmission gear 9 to rotate in the opposite direction, causing the rotating rollers 7 on both sides to rotate relative to each other. The two side retaining belts 5 rotate in opposite directions. The ends of the two side retaining belts 5 that are close to each other move in the same direction and are in the same direction as the conveyor belt 3. The motor 12 and the drive motor 4 start synchronously, and the side retaining belts 5 and the conveyor belt 3 run synchronously and at the same speed, so that the contact position between the side retaining belts 5 and the conveyor belt 3 is in a relatively stable state, reducing mutual wear between them and reducing the obstruction of the side retaining belts 5 to the material. As the bidirectional screw 13 adjusts the distance between the two side retaining belts 5, the distance between the first sprocket 8 and the second sprocket 10 changes accordingly. The extension and retraction of the electric cylinder 103 can drive the moving block to move. Under the action of the compression spring, the tensioning wheel 102 is pressed against the chain surface to ensure the tension of the chain, thereby ensuring the cooperation effect between the chain and the first sprocket 8 and the second sprocket 10, and adapting to the movement of the side retaining belts 5.

[0021] like Figures 1 to 3 As shown, the support roller 15 is rotatably mounted on the frame 1. Multiple support rollers 15 are provided to support the bottom of the working area of ​​the conveyor belt 3. The support roller 15 supports the working area of ​​the conveyor belt 3, that is, the upper section, to ensure the stability of the conveyor belt 3, thereby maintaining the fit between the conveyor belt 3 and the side baffle belt 5 and reducing material falling.

[0022] The cleaning unit is used to clean the surfaces of the conveyor belt 3 and the side retaining belt 5, such as... Figures 6 to 7As shown, the cleaning mechanism includes a conveying cleaning component and a material-blocking cleaning component. The conveying cleaning component includes a spray pipe 201 and a drying roller 202. The spray pipe 201 is mounted on the frame 1 and located below the conveyor belt 3. The spray pipe 201 has several spray holes for spraying onto the surface of the conveyor belt 3. The drying roller 202 is mounted on the frame 1 and contacts the bottom end of the conveyor belt 3. The drying roller 202 is located behind the spray pipe 201 along the direction of movement of the conveyor belt 3. Multiple drying rollers 202 are provided, such as... Figure 8 As shown, a conversion frame 203 is rotatably mounted on the frame 1, and a wiping roller 202 is rotatably mounted on the conversion frame 203 to replace the wiping roller 202 that contacts the conveyor belt 3. A motor 204 is mounted on the frame 1, and the shaft of the conversion frame 203 is fixedly mounted on the output end of the motor 204. The spray pipe 201 is connected to an external liquid delivery device, such as a delivery pump. The external liquid delivery device delivers clean water into the spray pipe 201 and sprays it onto the surface of the conveyor belt 3 through spray holes to rinse and clean the surface of the conveyor belt 3. As the conveyor belt 3 rotates, it can drive the wiping roller 202 to rotate. The wiping roller 202 contacts the conveyor belt 3 at different positions to wipe the surface of the conveyor belt 3, achieving the functions of cleaning and drying. The conversion frame 203 can be rotated by the motor 204 to replace the wiping roller 202 that contacts the conveyor belt 3 for wiping, ensuring the water absorption effect of the wiping roller 202.

[0023] like Figures 6 to 9 As shown, a drying chamber 16 is installed on the frame 1. The drying chamber 16 is connected to a fan 17. A heater 18 is installed inside the drying chamber 16. The drying chamber 16 has an opening for the wiping roller 202 to enter and exit and for the conversion frame 203 to rotate. The drying chamber 16 is connected to a drying pipe 19, which has an air outlet facing the lower side of the conveyor belt 3. When the motor 3 204 drives the conversion frame 203 to rotate, it causes one wiping roller 202 to be in close contact with the conveyor belt 3 for wiping. The other wiping roller 202 is located inside the drying chamber 16. The fan 17 blows air into the drying chamber 16. Air is supplied through heater 18 to heat the inside of drying chamber 16. The hot air dries the wiping roller 202 and blows out the water vapor, ensuring the wiping roller 202 has a good water absorption effect, thus ensuring the wiping effect on conveyor belt 3. At the same time, some hot air is blown onto conveyor belt 3 through drying pipe 19 to further dry conveyor belt 3, ensuring the cleanliness of conveyor belt 3 and reducing the adhesion of materials on conveyor belt 3. When the wiping roller 202 enters the drying chamber 16, it is pressed against the bottom wall of the drying chamber 16, which can play a squeezing role and help squeeze out the water in the wiping roller 202.

[0024] like Figure 1 and Figure 10As shown, the material blocking and cleaning component includes a sweeping roller 301, which is disposed on the outside of the side material blocking belt 5. A brush 302 is disposed on the outside of the sweeping roller 301 for cleaning the surface of the side material blocking belt 5. The sweeping roller 301 is rotatably mounted on the adjusting plate 6. The brush 302 contacts the surface of the side material blocking belt 5. As the side material blocking belt 5 rotates, it drives the sweeping roller 301 and the brush 302 to rotate. The brush 302 cleans the surface of the side material blocking belt 5, reducing the adhesion of debris on the side material blocking belt 5. The brush 302 is cleaned regularly to reduce the accumulation of debris inside the brush 302, ensuring the cleaning effect of the side material blocking belt 5.

[0025] like Figure 1 , Figure 2 and Figure 6 As shown, a debris collection bin 20 is installed on the frame 1 to collect material debris after cleaning. The debris collection bin 20 is located below the conveyor belt 3. A debris baffle 21 is provided on the frame 1. The sweeping roller 301 is located inside the debris baffle 21 to block the swept debris and make it fall into the debris collection bin 20. The surfaces of the debris baffle 21 and the side baffle belt 5 are close to each other. The bottom of the debris baffle 21 has an open structure to block the debris swept off by the sweeping roller 301. The swept debris falls into the debris collection bin 20 for collection. The debris and water washed off by the spray pipe 201 and the debris wiped off by the drying roller 202 also fall into the debris collection bin 20 for collection. The debris collection bin 20 can be cleaned periodically.

[0026] The working principle or usage process of this food processing raw material transport device with anti-drop function is as follows: In use, according to the width of the food raw material being conveyed, motor 2 14 drives the bidirectional screw 13 to rotate, adjusting the distance between the two adjusting plates and the side baffle belt 5. The bottom end of the side baffle belt 5 is attached to the surface of the conveyor belt 3, and the distance is slightly larger than the width of the raw material. The drive motor 4 and motor 1 12 are started to drive the drive roller 2 and the rotating roller 7 to rotate synchronously. The conveyor belt 3 and the side baffle belt 5 start to run. The raw material is placed above the conveyor belt 3. The side baffle belts 5 on both sides effectively prevent the raw material from falling from the edge. During the conveying process, the cleaning mechanism works simultaneously. The spray pipe 201 sprays cleaning liquid onto the lower surface of the return section of the conveyor belt 3, and the wiping roller 202 then wipes away the surface moisture. The drying box 16 and the blowing pipe 19 use hot air to dry the conveyor belt 3 and the wiping roller 202. The sweeping roller 301 continuously sweeps the surface of the side baffle belt 5, and the swept debris falls into the debris collection bin 20. The motor 3 204 periodically drives the conversion frame 203 to rotate, so that the wiping roller 202 can be replaced. The drying box 16 dries the wiping roller 202 inside to ensure the drying effect of the wiping roller 202.

[0027] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
