Description

Technical Field

[0001] This invention belongs to the technical field of turnover box processing equipment, specifically relating to an automatic clamping and reversing device for box cleaning and drying. Background Technology

[0002] Plastic turnover boxes are standardized logistics containers made of high-density polyethylene or polypropylene through one-time injection molding. They are specifically designed for the cyclical turnover and unitized management of goods in transportation, warehousing, distribution, and production processes. They are non-toxic, odorless, and recyclable, aligning with the trend of green logistics. Furthermore, the plastic turnover boxes feature raised ribs on the top and corresponding grooves on the bottom to ensure stability when stacked in multiple layers.

[0003] Plastic turnover boxes are prone to getting contaminated with dust, oil, residues and pathogens during repeated use. In order to avoid secondary pollution of goods and affect the sensory quality of goods, plastic turnover boxes need to be cleaned regularly.

[0004] The existing cleaning method involves attaching the plastic turnover box as shown. Figure 1 The plastic turnover boxes are placed upside down on the conveyor belt of the washing machine, allowing their surfaces to be rinsed with high-pressure water. Then, hot air is used to dry the boxes, removing surface moisture and preventing the growth of microorganisms in a damp environment. Air knives for blowing hot air are located on both sides of the conveyor belt. To ensure the hot air reaches all surfaces of the turnover boxes, they need to be rotated 90° during transport. Summary of the Invention

A shaft is fixedly installed eccentrically on the side of the wing away from the clamping plate. A connecting rod is rotatably sleeved on the outside of the shaft. The bottom end of the connecting rod is rotatably connected to the side wall of the relay plate.

[0009] In this invention, a first stop block is fixedly provided on the side of the wing plate near the clamping plate, and a second stop block is fixedly provided on the side of the clamping plate near the wing plate. A torsion spring is also sleeved outside the fixed shaft, and the two torsion arms of the torsion spring abut against the adjacent first stop block and second stop block respectively.

[0010] In this invention, an arc-shaped water guide plate is provided below the mounting plate, and the outer side walls at both ends of the water guide plate are fixedly connected to the bottom of the mounting plate and the bottom of the outer side wall of the air knife, respectively.

[0011] In this invention, the side wall of the main beam is slidably connected to a movable plate. A vertical plate is fixedly arranged at intervals on one side of the movable plate, and a third motor is fixedly arranged on the other side. The lifting assembly includes a vertical rod. Limiting blocks are fixedly arranged on the side of the two vertical plates that are close to each other. Guide grooves are provided on the side of the limiting blocks that are close to each other.

[0021] Example: As attached Figure 1-7 As shown, this invention discloses an automatic clamping and reversing device for cleaning and drying boxes, including a main beam 20. A base plate 31 is slidably disposed below the main beam 20. A lifting assembly is provided between the main beam 20 and the base plate 31. A frame 32 is rotatably disposed at the bottom of the base plate 31. A first motor 41 that drives the frame 32 to rotate is fixedly disposed at the top of the base plate 31. Clamping assemblies 50 are respectively disposed on the bottom of both sides of the frame 32 along a first direction. The clamping assembly 50 includes a bidirectional screw 51 arranged along a second direction and rotatably connected to the frame 32. The forward and reverse threaded sections of the bidirectional screw 51 are respectively fitted with sliders 52. The sliders 52 are slidably connected to the frame 32. An L-shaped clamping plate 53 is fixedly disposed at the bottom of each slider 52. The two clamping plates 53 of the same clamping assembly 50 are symmetrically arranged. A second motor 42 that is throttledly connected to the bidirectional screws 51 of the two clamping assemblies 50 is fixedly disposed at the top of the frame 32. An air blowing assembly 60 is also disposed on the vertical section of each clamping plate 53.

[0022] In this embodiment, an inner edge 531 is fixedly provided at the bottom of the inner sidewall of the vertical section of the clamping plate 53.

[0023] In this embodiment, fixed shafts 532 are fixedly installed on both sides of the vertical section of the clamping plate 53. The air blowing assembly 60 includes a mounting plate 61. Wing plates 62 are fixedly installed at intervals on the top of the mounting plate 61. An air knife 63 is fixedly installed on the bottom of the mounting plate 61 along its length. The two wing plates 62 are rotatably sleeved on the corresponding fixed shafts 532. A relay plate 64 is movably installed on the inner side of the vertical section of the clamping plate 53. A guide rod 641 is fixedly installed on the side of the relay plate 64 near the clamping plate 53 and slidably inserted into the clamping plate 53. A shaft body 621 is fixedly installed eccentrically on the side of the wing plate 62 away from the clamping plate 53 and fixedly installed on the fixed shaft 532. A connecting rod 65 is rotatably sleeved on the outside of the shaft body 621. The bottom end of the connecting rod 65 is rotatably connected to the side wall of the relay plate 64.

[0024] In this embodiment, a first stop 622 is fixedly provided on the side of the wing plate 62 near the clamping plate 53, and a second stop 533 is fixedly provided on the side of the clamping plate 53 near the wing plate 62. A torsion spring 66 is also sleeved on the outside of the fixed shaft 532, and the two torsion arms of the torsion spring 66 abut against the adjacent first stop 622 and second stop 533 respectively.

[0025] In this embodiment, an arc-shaped water guide plate 67 is provided below the mounting plate 61, and the outer side walls at both ends of the water guide plate 67 are fixedly connected to the bottom of the mounting plate 61 and the bottom of the outer side wall of the air knife 63, respectively.

[0026] In this embodiment, a movable plate 70 is slidably connected to the side wall of the main beam 20. A vertical plate 71 is fixedly arranged at intervals on one side of the movable plate 70, and a third motor 43 is fixedly arranged on the other side. The lifting assembly includes a vertical rod 81. Limiting blocks 72 are fixedly arranged on the side of the two vertical plates 71 that are close to each other. Guide grooves are provided on the side of the limiting blocks 72 that are close to each other. The vertical rod 81 is movably arranged between the two limiting blocks 72. A guide rail 82 that is slidably embedded in the corresponding guide groove is fixedly arranged on the outer side wall of the vertical rod 81. A first gear 83 is connected to the output end of the third motor 43. A rack 84 that is arranged vertically and meshes with the first gear 83 is also fixedly arranged on the outer side wall of the vertical rod 81.

[0027] In this embodiment, a second pulley 55 is fixedly sleeved on the output end of the second motor 42, and a first pulley 54 is fixedly sleeved on the outer side of one end of each of the two bidirectional screws 51. A synchronous belt 56 is wound around the second pulley 55 and the two first pulleys 54.

[0028] In this embodiment, tensioning wheels 33 are rotatably provided on both sides of the second pulley 55 on the sidewall of the frame 32, and the two tensioning wheels 33 respectively roll into contact with the outer sidewall of the synchronous belt 56.

[0029] In this embodiment, two sets of limit sensors 90 are fixedly arranged at intervals on one side of the frame 32, and one of the sliders 52 of the clamping assembly 50 can trigger the two limit sensors 90 respectively.

[0030] In this embodiment, the output end of the first motor 41 is connected to a second gear, and an internal gear ring is fixedly provided on the top of the frame 32. The second gear is eccentrically arranged around the internal gear ring and meshes with the internal gear ring.

[0031] In this embodiment, the main beam 20 is provided with a linear motion module 44 that drives the movable plate 70 to move back and forth.

[0032] The specific implementation process is as follows: In the initial state, the first direction of the frame 32 is parallel to the moving direction of the conveyor belt structure, the two clamping plates 53 of the same clamping assembly 50 are far apart from each other, and the mounting plates 61 of each air blowing assembly 60 are in a vertical state. When the turnover box 10 to be dried moves to below the frame 32, the third motor 43 first drives the first gear 83 to rotate. Because the first gear 83 meshes with the rack 84, and each of the guide rails 82 is slidably embedded in the corresponding guide groove, the rack 84 cannot rotate with the first gear 83, thereby causing the rack 84 to drive the vertical rod 81 to move downward.

[0033] When the vertical rod 81 moves downward, the base plate 31, frame 32 and clamping assembly 50 move downward accordingly until the inner edge 531 of the clamping plate 53 moves to the bottom of the groove 11 of the turnover box body 10. Then, the second motor 42 drives the second pulley 55 to rotate. Since the synchronous belt 56 is wrapped around the second pulley 55 and the two sets of first pulleys 54, it drives the two sets of first pulleys 54 and the corresponding bidirectional screws 51 to rotate. Since the slider 52 is slidably connected to the frame 32, the frame 32 prevents the slider 52 from rotating. The slider 52 is fitted into the threaded section of the bidirectional screw 51, thereby causing the two sliders 52 of the same clamping assembly 50 to drive the corresponding clamping plates 53 to move closer to each other.

[0034] During the process of the two clamping plates 53 of the same clamping assembly 50 moving towards each other, the relay plate 64 first contacts the side wall of the turnover box body 10. As the clamping plates 53 continue to move, the turnover box body 10 pushes the relay plate 64 to move closer to the clamping plates 53. When the relay plate 64 moves, it pushes the wing plate 62 to rotate through the connecting rod 65. The rotation of the wing plate 62 drives the mounting plate 61 and the air knife to rotate. The torsion spring 66 is compressed and deformed during this process until the turnover box body 10, the relay plate 64 and the clamping plates 53 are pressed together in sequence. At this time, the mounting plate 61 is in a horizontal state and the air knife 63 is aligned with the groove body 11.

[0035] The third motor 43 reverses the rotation of the first gear 83, thereby driving the vertical rod 81 to move upward. The inner edge 531 of the clamping plate 53 lifts the turnover box body 10. At the same time, the first motor 41 drives the frame 32 to rotate relative to the base plate 31. During the rotation of the turnover box body 10, the air knife 63 blows high-pressure gas into the tank 11, using the airflow to blow out the water in the tank 11 and quickly peel off the water adhering to the inner side wall of the tank 11. The water guide plate 67 guides the airflow mixed with water to the outside of the turnover box body 10.

[0036] When the frame 32 rotates to a position where its second direction is parallel to the direction of movement of the conveyor belt structure, the third motor 43 drives the vertical rod 81 to move downwards again. When the bottom of the turnover box 10 contacts the top of the conveyor belt structure, the second motor 42 drives the two clamping plates 53 of the same clamping assembly 50 to move away from each other. The elastic force of the torsion spring 66 pushes the wing plate 62 to rotate, which in turn causes the wing plate 62 to push the relay plate 64 to reset through the connecting rod 65 until the relay plate 64 is separated from the turnover box 10. At this time, the mounting plate 61 rotates to a vertical position.

[0037] During the above steps, the linear motion module 44 drives the movable plate 70 to move in the same direction as the conveyor belt structure. After the rotated turnover box 10 is placed on the conveyor belt structure, the linear motion module 44 drives the movable plate 70 to move in the opposite direction to the conveyor belt structure, and the first motor 41 drives the frame 32 to rotate 90° in the opposite direction to reset it.

[0038] The parts of the device not covered herein are the same as or can be implemented using existing technologies.
