[0018] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Example: Please refer to Figure 1 - Figure 8A conveying device for food processing includes a frame 1, a power mechanism, and a conveyor belt 2. The power mechanism is mounted on the frame 1 and drives the conveyor belt 2. It also includes: The guide and protection mechanism includes a slope assembly mounted on a frame 1 and a guide seat 3 disposed on the top of the conveyor belt 2. The slope assembly includes a guide roller 12, a first limiting roller 13, and two second limiting rollers 14 mounted inside the frame 1. The guide roller 12 is located inside the conveyor belt 2, lifting the conveyor belt 2 to form a slope 28. The first limiting roller 13 is located on one side of the guide roller 12 and on the top of the conveyor belt 2, used to limit the height of the lower edge of one side of the slope 28. The two second limiting rollers 14 are located on the other side of the guide roller 12. On one side, and located at the top of the conveyor belt 2, it is used to limit the height of the lower edge of the other side of the ramp 28; the front and rear sides of the conveyor belt 2 extend into the interior of the frame 1, and the opposite ends of the two second limiting rollers 14 are flush with the inner sidewall of the frame 1. The guide seat 3 is installed on the inner wall of the frame 1 and is located at the top of the downhill section of the ramp 28; a belt conveyor component 15 is installed along its length on the side of the guide seat 3 facing the top of the ramp 28, for conveying the mooncakes on the downhill section of the ramp 28 along the downward direction of the guide seat 3. Workers place the baked mooncakes from the tray on the top left side of conveyor belt 2. The conveyor belt 2 then transports the mooncakes to the right. After moving a certain distance to the right, the mooncakes enter the ramp 28 area and begin to ascend. As the mooncakes descend, their center of gravity tilts downwards instead of vertically downwards. Therefore, when the mooncakes descend to contact the belt conveyor component 15 on the guide seat 3, because their center of gravity is tilted downwards, the point of gravity is concentrated at the contact point with the belt conveyor component 15. The belt conveyor component 15 drives the mooncakes forward, gradually guiding them into a straight line on conveyor belt 2 for subsequent individual processing. For example, when packaging mooncakes individually, they need to be transferred from a wider conveyor to a narrower conveyor that can only accommodate a single mooncake. During the reversal process, the friction between the mooncakes and conveyor belt 2 is effectively reduced, improving the integrity of the mooncake processing.

[0020] The cleaning box 4 is installed inside the frame 1 and below the conveyor belt 2. A drain pipe 22 is installed on the bottom of one side of the cleaning box 4 for draining and venting. The sealing connection mechanism includes multiple electric push rods 5 installed on the frame 1, a sealing gasket 6 installed on the top of the cleaning box 4, and multiple suction cups 7 installed inside the sealing gasket 6 along its trajectory. The extended ends of the electric push rods 5 are fixedly connected to the bottom of the cleaning box 4. A vacuum pump 16 is installed at the bottom of the cleaning box 4. The vacuum pump 16 is connected to the multiple suction cups 7 through a vacuum pipe 17. When it is necessary to clean the conveyor belt 2, first stop the machine, then control the electric push rod 5 to move the cleaning box 4 to the set position, that is, the position where the sealing gasket 6 and the bottom of the conveyor belt 2 abut. Control the vacuum pump 16 to work with each vacuum tube 17 to evacuate each suction cup 7, so that the bottom of the conveyor belt 2 and the top of the cleaning box 4 are sealed. After the current area at the bottom of conveyor belt 2 is cleaned, control vacuum pump 16 to release the seal on the bottom of conveyor belt 2, then drive conveyor belt 2 to move. The moving distance is less than the length of cleaning box 4. Then stop the machine and control vacuum pump 16 again to seal the bottom of conveyor belt 2 with cleaning box 4. Repeat this cycle to seal and clean conveyor belt 2 in sections.

[0021] The cleaning mechanism includes a slide 8 slidably connected inside the cleaning box 4, multiple spray heads 9 sequentially mounted on the top of the slide 8 along its length, multiple air jets 10 respectively disposed between two adjacent spray heads 9, soft brush strips 11 respectively disposed on both sides of the slide 8, and a displacement assembly for driving the slide 8 to reciprocate. Driven shafts 20 are rotatably connected to both sides of the slide 8, and connecting seats 21 are fixedly sleeved on the outside of each of the two driven shafts 20. Two soft brush strips 11 are respectively mounted on the top of the two connecting seats 21. The displacement assembly includes a reciprocating screw 23 rotatably connected inside the cleaning box 4 and a first motor 24 mounted on the outer wall of one side of the cleaning box 4. The output end of a motor 24 is fixedly connected to one end of a reciprocating screw 23; a slide 8 is threaded onto the outside of the reciprocating screw 23; two support rods are also fixedly installed inside the cleaning box 4, and the support rods are parallel to the reciprocating screw 23; the slide 8 is also slidably sleeved onto the outside of the two support rods; a water supply pipe 18 is connected to the bottom of multiple spray heads 9, the water supply pipe 18 is a metal braided hose, the bottom end of the water supply pipe 18 extends to the outside of the cleaning box 4 and is connected to a water supply device; an air inlet pipe 19 is connected to the bottom of multiple air jet heads 10, the air inlet pipe 19 is a high-temperature resistant metal braided hose, the bottom end of the air inlet pipe 19 extends to the outside of the cleaning box 4 and is connected to a hot air blower; After the cleaning box 4 seals the bottom of the conveyor belt 2, it controls the first motor 24 to drive the reciprocating screw 23 to rotate. The slide 8 moves back and forth along the outside of the reciprocating screw 23. During this process, water is supplied to the upper water pipe 18 by starting the water supply equipment. Multiple spray heads 9 spray the sealed area at the bottom of the conveyor belt 2 back and forth. At the same time, the soft brush strips 11 that move back and forth back and forth brush the sealed area at the bottom of the conveyor belt 2, which improves the cleaning effect of the bottom of the conveyor belt 2. After the bottom sealing area of ​​the conveyor belt 2 is cleaned, the two soft brush strips 11 are driven to rotate synchronously away from the spray head 9 to make room for the air jet head 10 to dry. The spray head 9 stops spraying and the hot air blower is started to provide high-temperature gas to the air inlet pipe 19. The cleaning area of ​​the conveyor belt 2 is dried through multiple air jet heads 10.

[0022] An adjustment mechanism, mounted on the slide 8, is used to adjust the angle of the two soft brush strips 11. The adjustment mechanism includes a second motor 25 installed inside the slide 8 and transmission components connected to the two driven shafts 20 respectively. The second motor 25 is a dual-axis motor, and the two output shafts of the second motor 25 rotate in the same direction. The transmission components include a first bevel gear 26 fixedly sleeved on the outside of the two output shafts of the second motor 25 and a second bevel gear 27 fixedly sleeved on the outside of the two driven shafts 20 respectively. The first bevel gear 26 meshes with the second bevel gear 27. After the bottom sealing area of ​​the conveyor belt 2 is cleaned, the second motor 25 is controlled to drive the two first bevel gears 26 to rotate counterclockwise in sync. Through the meshing action between the first bevel gear 26 and the second bevel gear 27, the two driven shafts 20 are driven to rotate away from the spray head 9. The two soft brush strips 11 rotate in sync away from the spray head 9 to make room for the air jet head 10 to dry. After cleaning the last section of conveyor belt 2, the second motor 25 is controlled to drive the two first bevel gears 26 to rotate synchronously clockwise. Through the meshing action between the first bevel gear 26 and the second bevel gear 27, the two driven shafts 20 are driven to rotate towards the spray head 9. Then, through the connecting seat 21, the soft brush strips 11 are driven to rotate above the spray head 9. The spray head 9 washes the two soft brush strips 11. Since the soft brush strips 11 are in an inclined state, the cleaned impurities are easy to flow out. In order to prevent impurities from adhering to the soft brush strips 11 after cleaning the conveyor belt 2, the two soft brush strips 11 can be driven to rotate away from the spray head 9 again to wash away the impurities adhering to the bottom of the conveyor belt 2. Finally, the air jet head 10 dries the last section of conveyor belt 2. At this time, the soft brush strips 11 that are inclined outward are dried simultaneously, realizing the effect of automated cleaning of the soft brush strips 11 and preventing the problem of bacteria growing easily when cleaning the food conveyor belt 2.

[0023] Working principle: During use, the staff places the baked mooncakes on the left side of the top of the conveyor belt 2. The conveyor belt 2 transports the mooncakes to the right. After moving a certain distance to the right, the mooncakes enter the ramp 28 area and begin to go uphill. When the mooncakes go downhill, their center of gravity becomes tilted downwards instead of vertically downwards. Therefore, when the mooncakes go downhill and come into contact with the belt conveyor component 15 on the guide seat 3, since the center of gravity of the mooncakes is tilted downwards at this time, the gravity point is concentrated at the contact point with the belt conveyor component 15. The belt conveyor component 15 drives the mooncakes forward, gradually guiding the mooncakes into a straight line on the conveyor belt 2 for subsequent processing of the mooncakes one by one. For example, when packaging the mooncakes individually, the mooncakes need to be transferred from a wider conveyor device to a narrower conveyor device that can only pass one mooncake at a time. During the process of changing the direction of the mooncakes, the friction between the mooncakes and the conveyor belt 2 is effectively reduced, improving the integrity of the mooncake processing process. When cleaning of conveyor belt 2 is required, first stop the machine, then control the electric push rod 5 to move the cleaning box 4 to the set position, which is the position where the sealing gasket 6 abuts against the bottom of the conveyor belt 2. Control the vacuum pump 16 in conjunction with each vacuum tube 17 to evacuate each suction cup 7, thereby sealing the bottom of the conveyor belt 2 with the top of the cleaning box 4. Control the first motor 24 to drive the reciprocating screw 23 to rotate, and the slide 8 moves back and forth along the outside of the reciprocating screw 23. During this process, water is supplied to the upper water pipe 18 by starting the water supply equipment, and water is sprayed through multiple nozzles. The spray head 9 sprays the bottom sealing area of ​​the conveyor belt 2 back and forth, while the soft brush strips 11 move back and forth to the left and right to scrub the bottom sealing area of ​​the conveyor belt 2, which improves the cleaning effect of the bottom of the conveyor belt 2. After the bottom sealing area of ​​the conveyor belt 2 is cleaned, the two soft brush strips 11 are driven to rotate synchronously away from the spray head 9 to make room for the air jet head 10 to dry. The spray head 9 stops spraying and the hot air fan is started to provide high temperature gas to the air inlet pipe 19. The cleaned area of ​​the conveyor belt 2 is dried through multiple air jet heads 10.
