The left part of the baffle 15 is slidably connected with a second supporting sleeve 18, and the second conveying roller 6 is located in the second supporting sleeve 18. A retracting and unfolding mechanism for controlling the unfolding and retracting of the baffle 15 is provided on the mounting frame 1, and an adjusting mechanism for adjusting the tightness of the conveyor belt 7 is provided on the mounting frame 1.

[0037] like Figure 7 and Figure 8 As shown, the retracting and unfolding mechanism includes a slide rail 19, a slider 20, a slide plate 21, a connecting rod 22 and a turntable 23. The left and right sides of the front side of the mounting frame 1 are connected to the slide rail 19 by bolts. The slider 20 is slidably connected in the slide rail 19. The front side of the slider 20 is connected to the slide plate 21. The slide plate 21 slides through the front side of the slide rail 19. The front side of the slide plate 21 is rotatably connected to the connecting rod 22. The left and right ends of the rotating shaft 14 are connected to a turntable 23 that rotates together. The connecting rod 22 is rotatably connected to the eccentric position of the turntable 23.

[0038] like Fig. 9 and Fig.10 As shown, the adjustment mechanism includes a first screw motor 24 and a second screw motor 25. The first screw motor 24 is installed on the left front side of the baffle 15, and the screw of the first screw motor 24 is connected to the first support sleeve 17 by threads. The second screw motor 25 is installed on the upper left rear side of the mounting frame 1, and the screw of the second screw motor 25 is connected to the mounting sleeve 5 by threads.

[0039] The staff starts the servo motor 4, and the output shaft of the servo motor 4 drives the first conveyor roller 3 to rotate, and the first conveyor roller 3 drives the conveyor belt 7 to rotate, and the healthy food is placed on the conveyor belt 7, and the conveyor belt 7 transports the healthy food to the designated position. The support plate 8 can support the conveyor belt 7 to improve the stability of the conveyor belt 7. When the conveyor belt 7 needs to be replaced, the servo motor 4 is turned off, and then the first screw motor 24 is controlled to drive the first support sleeve 17 to move to the right. At the same time, the second screw motor 25 is controlled to drive the installation sleeve 5 to move to the right. The first support sleeve 17 and the installation sleeve 5 drive the second conveyor roller 6 to move to the right, so that the conveyor belt 7 becomes loose, and then the movable end of the cylinder 9 is controlled to extend to drive The push plate 10 and the pull plate 11 move forward. When the push plate 10 moves forward and contacts the moving plate 13, the push plate 10 pushes the moving plate 13 to move forward. The moving plate 13 drives the rotating shaft 14 and the baffle plate 15 to move forward. The baffle plate 15 drives the first support sleeve 17 and the second support sleeve 18 to move forward, so that the first support sleeve 17 and the first conveying roller 3 are disengaged, and the second support sleeve 18 and the second conveying roller 6 are disengaged. The rotating shaft 14 moves forward and can also drive the turntable 23 to move forward. The turntable 23 drives the connecting rod 22 and the slide plate 21 to move forward. The slide plate 21 drives the slider 20 to move forward. When the slider 20 moves forward to the frontmost side of the slide rail 19, the slider 20 stops moving forward, and the slide plate 21 and connecting rod 22 also stop moving forward. At this time, the rotating shaft 14 continues to move forward, and the rotating disk 23 also continues to move forward. The connecting rod 22 will pull the rotating disk 23 to rotate the rotating disk 23, and the rotating disk 23 drives the rotating shaft 14 to rotate. The rotating shaft 14 drives the baffle 15 to rotate downward to a horizontal state, and the baffle 15 is unfolded to facilitate the staff to remove the conveyor belt 7 and then replace the conveyor belt 7, thereby improving the output efficiency. At this time, the tension spring 16 is stretched. After the conveyor belt 7 is replaced, the active end of the control cylinder 9 is shortened, driving the push plate 10 and the pull plate 11 to move backward. The push plate 10 moves backward and disengages from the moving plate 13. Under the action of the tension spring 16, the baffle 15 moves upward Rotate to a vertical state and retract the baffle 15. When the pull plate 11 moves backward and contacts the movable plate 13, the pull plate 11 pulls the movable plate 13 backward, and the movable plate 13 drives the rotating shaft 14 and the baffle 15 to move backward. The baffle 15 drives the first support sleeve 17 and the second support sleeve 18 to move backward, so that the first support sleeve 17 and the first conveying roller 3 are re-matched, and the second support sleeve 18 and the second conveying roller 6 are re-matched. Then the first screw motor 24 is controlled to drive the first support sleeve 17 to move to the left. At the same time, the second screw motor 25 is controlled to drive the installation sleeve 5 to move to the left. The first support sleeve 17 and the installation sleeve 5 drive the second conveying roller 6 to move to the left to tighten the conveyor belt 7.

[0040] Embodiment 2: Based on embodiment 1, Figure 12-Figure 15As shown, a cleaning mechanism is also included, which includes a box 26, a hard pipe 27, a nozzle 28, a partition 29, a contact strip 30, a discharge pipe 31, a contact frame 32, a movable frame 33, a push block 34 and a limit ring 35. The box 26 is slidably connected to the right front side of the mounting frame 1, and the hard pipe 27 is connected to the left and right sides of the front side of the box 26. Five nozzles 28 are evenly spaced and connected to the top of the hard pipe 27. A partition 29 is connected to the middle part of the box 26, and the contact strip 30 is connected to the top of the partition 29. The left and right sides of the bottom of the box 26 are connected to the discharge pipe 31, and the middle of the bottom of the box 26 is connected to the contact frame 32. The movable frame 33 is connected to the right side of the push plate 10, and the push block 34 is connected to the right side of the top of the movable frame 33 by bolts. The front and rear sides of the top of the push block 34 are provided with inclined surfaces 341. The side where the mounting frame 1 and the baffle 15 are close to each other is connected to the limit ring 35, and the first conveying roller 3 and the second conveying roller 6 are both located in the limit ring 35.

[0041] like Fig.16 As shown, a wiping mechanism is also included, which includes a frame 36, wiping cotton 37 and a locking block 38. The upper left side of the box body 26 is connected to the frame 36 by bolts, the wiping cotton 37 is placed in the frame 36, and the locking block 38 is connected to the left side of the frame 36 by threads.

[0042] like Fig.17 and Fig.18 As shown, a disinfection mechanism is also included, which includes a mounting frame 39 and an ultraviolet lamp 40. The mounting frame 39 is connected to the middle of the upper front side of the mounting frame 1 by bolts, and four ultraviolet lamps 40 are evenly spaced and connected in the mounting frame 39.

[0043] like Fig.13 As shown, a sealing strip 41 is also included, and the front and rear sides of the top of the box body 26 are connected with the sealing strip 41.

[0044] like Fig.14 As shown, a roller 42 is also included, and the front and rear sides of the lower part of the contact frame 32 are rotatably connected with the roller 42.

[0045] like Fig.12 As shown, a guide sleeve 43 is also included. The right side of the mounting frame 1 is connected with the guide sleeve 43 by bolts. The push block 34 is located in the guide sleeve 43, and the push block 34 and the guide sleeve 43 are slidably connected.

[0046] When it is necessary to clean the conveyor belt 7, the movable end of the control cylinder 9 is extended to drive the push plate 10 to move forward, and the push plate 10 drives the movable frame 33 and the push block 34 to move forward. The push block 34 pushes the contact frame 32 to move upward through the inclined surface 341 on the front side, and the contact frame 32 drives the box body 26 to move upward, so that the top of the box body 26 contacts the bottom of the limit ring 35, and the contact strip 30 contacts the conveyor belt 7. The sealing strip 41 can improve the sealing between the box body 26 and the limit ring 35, and the roller 4 2 can reduce the friction between the push block 34 and the contact frame 32, so that the contact frame 32 moves upward more smoothly. The guide sleeve 43 can guide the push block 34 to improve the stability of the push block 34. The upward movement of the box body 26 can also drive the frame body 36 to move upward. The frame body 36 drives the wiping cotton 37 to make the wiping cotton 37 contact with the conveyor belt 7. After the inclined surface 341 on the front side of the push block 34 is out of contact with the contact frame 32, the top of the box body 26 just contacts with the bottom of the limit ring 35. At this time, the push plate 10 does not contact with the movable plate 13, and the movable plate 13 will not move. The staff closes the cylinder 9, and then connects the hard tube 27 on the left to hot water, and connects the hard tube 27 on the right to a cleaning agent. The cleaning agent is sprayed out through the nozzle 28 on the right and sprayed on the conveyor belt 7 to remove dirt and microorganisms on the surface of the conveyor belt 7. Hot water is sprayed out through the nozzle 28 on the left and sprayed on the conveyor belt 7 to remove residual chemicals and loose stains on the surface of the conveyor belt 7 to keep the conveyor belt 7 clean. The servo motor 4 is started to rotate the conveyor belt 7 so as to clean the entire conveyor belt 7. The partition 29 can separate the two hard tubes 27, thereby separating the cleaning agent and hot water to prevent the cleaning agent and hot water from mixing together. The wiping cotton 37 can wipe the cleaned conveyor belt 7 to dry the residual moisture on the conveyor belt 7. The locking block 38 can lock the wiping cotton 37 to prevent the wiping cotton 37 from moving. The ultraviolet lamp 40 can disinfect the cleaned conveyor belt 7 to prevent bacteria from infecting healthy food.
