[0002] A plate conveyor is a device that uses a chain to drive a rigid material plate to move, thereby transporting goods through the plate. It has the advantages of large load capacity, stable operation, and the ability to be integrated with assembly line equipment for material transport and transfer. However, there are also disadvantages to using plate conveyors. Due to their excellent load-bearing and transport performance, the range of goods that can be transported is extremely wide. Some goods, due to their inherent contamination properties, can contaminate the material plate of the plate conveyor. If the stains on the material plate are not cleaned for a long time, it can easily cause damage to the plate surface and contamination of the goods. Therefore, the plate conveyor needs to have a self-cleaning function. Utility Model Content

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figure 1-5 As shown, the specific implementation adopts the following technical solution:

[0029] This specific embodiment includes a workbench 1 and a plate-type stepping unit 2. The plate-type stepping unit 2 is fixedly mounted on the workbench 1. Two sets of cleaning units 9 are mounted above the plate-type stepping unit 2, and each set of cleaning units 9 consists of two units arranged symmetrically front to back. Support frames 3 are symmetrically fixedly mounted on the front and rear side walls of the workbench 1. Support seats 4 are symmetrically fixedly mounted on the left and right ends of the upper surface of the support frame 3. Lifting guide rods 5 are fixedly mounted on the support seats 4, and lifting seats 6 are movably sleeved on the lifting guide rods 5. Between the two lifting seats 6 on the left and right sides... A stepping guide rod 7 is installed, with its left and right ends fixedly mounted on the left and right lifting seats 6 respectively. A lifting frame 10 is installed above the support frame 3, with the left and right lifting seats 6 fixedly mounted on the left and right ends of the lifting frame 10 respectively. A lifting screw pair 11 is fixedly installed on the support frame 3, with the screw of the lifting screw pair 11 threadedly threaded onto the lifting frame 10. The stepping guide rod 7 is installed on the side of the lifting frame 10, with its left and right ends fixedly mounted on the left and right lifting seats 6 respectively. A movable sleeve is mounted on the stepping guide rod 7. A stepper seat 8 is provided, and a cleaning unit 9 is fixedly mounted on the stepper seat 8. A return spring 18 is fixedly sleeved on the left end of the stepper guide rod 7, and the right end of the return spring 18 is movably abutted against the left side wall of the stepper seat 8. An electromagnetic locking pin 19 is fixedly mounted on the left lifting seat 6 of the set, and an electromagnetic lock body 20 is fixedly mounted on the left side wall of the stepper seat 8. The electromagnetic locking pin 19 and the electromagnetic lock body 20 are configured to cooperate. A guide groove 15 is provided on the lower side wall of the stepper seat 8, and a drive connecting seat 13 is slidably mounted in the guide groove 15. A threaded rod 12 is provided between the two support seats 4 of the set. The threaded rod 12 is screwed onto the support base 4 via a bearing. The lower inner wall of the drive connecting base 13 is integrally formed with a keyway that matches the threaded groove on the drive threaded rod 12. A servo motor 14 is fixedly mounted on the bracket, and the servo motor 14 is connected to the right end shaft of the threaded rod 12 via a drive transmission. A buffer guide rod 16 is fixedly mounted on the drive connecting base 13, and the buffer guide rod 16 is movably mounted on the stepper base 8. Buffer springs 17 are fixedly sleeved on both ends of the buffer guide rod 16, and the movable end of the buffer spring 17 is movably abutted against the side wall of the stepper base 8.

[0030] When using this device, the material carrier plate on the plate stepping unit 2 moves from right to left. During cleaning of the material carrier plate on the plate stepping unit 2, the lifting frame 10 is moved downwards via the lifting screw pair 11. This, in turn, causes the lifting frame 10 to move downwards on the lifting guide rod 5. The lifting seat 6 then moves the stepping guide rod 7 downwards, which in turn moves the stepping seat 8 downwards. Consequently, the cleaning unit 9 on the stepping seat 8 moves downwards and covers the material carrier plate of the plate stepping unit 2. As the stepping seat 8 descends, the cleaning unit 9... Covering the plate-type stepper unit 2, the stepper seat 8 drives the drive connecting seat 13 on it to move downwards and engage with the threaded rod 12, so that the keyway on the drive connecting seat 13 and the threaded groove on the threaded rod 12 mesh with each other. The servo motor 14 drives the threaded rod 12 to rotate, and the threaded rod 12 pushes the meshing drive connecting seat 13 to move to the left. The drive connecting seat 13, through the buffer guide rod 16 and its buffer spring 17, pushes the stepper seat 8 to the left, and the stepper seat 8 drives the cleaning unit 9 to move to the left. The cleaning unit 9... The moving speed of the stepper 8 is the same as the moving speed of the material plate on the plate stepper unit 2. Thus, the cleaning unit 9 moves along with the material plate on the plate stepper unit 2 and cleans the material plate. When the stepper seat 8 moves to the left, the return spring 18 is pressed. When the stepper seat 8 moves to the left end of the stepping guide rod 7, the electromagnetic locking pin 19 on the left lifting seat 6 is inserted into the electromagnetic locking body 20 on the stepper seat 8, locking the stepper seat 8 and the left lifting seat 6 together. After cleaning, the lifting frame 10 is raised via the lifting screw pair 11. Pushing upwards causes the stepper seat 8 to move upwards, lifting the cleaning unit 9 off the material carrier plate of the plate-type feed unit. After the lifting frame 10 lifts the lifting seat 6 to the upper end of the lifting guide rod 5, the electromagnetic lock body 20 is unlocked. This causes the reset spring 18 to push the stepper seat 8 to the right, moving it to the right end of the stepping guide rod 7 to reset. Thus, through the alternating operation of the two stepper seats 8, the two cleaning units 9 alternately cover the material carrier plate of the plate-type stepping unit 2 to clean the material carrier plate.

[0031] Compared with the prior art, the beneficial effects of this utility model are:

[0032] 1. This device sets up a cleaning unit 9 that moves with the plate stepping unit 2, and sets up two sets of cleaning units 9 to work alternately. This enables the cleaning unit 9 to follow the movement of the material plate on the plate stepping unit 2 to achieve a follow-up cleaning operation, so that the cleaning of a single material plate can be maintained for a longer time and the cleaning can be thorough.

[0033] 2. This device is equipped with a drive connecting seat 13 on the stepper seat 8 that cooperates with the threaded rod 12, so that after the stepper seat 8 descends, the drive connecting seat 13 and the threaded rod 12 are engaged to realize the movement drive of the stepper seat 8.

[0034] 3. This device has a return spring 18 on the stepper guide rod 7, which pushes the stepper seat 8 to reset. An electromagnetic locking pin 19, which cooperates with the electromagnetic lock body 20 on the stepper seat 8, is provided on the lifting seat 6 on one side. This allows the return spring 18 to be held in place by the two locking pins after the stepper seat 8 has moved, and the electromagnetic locking pin 19 to be released after the stepper seat 8 is lifted, allowing the return spring 18 to push the stepper seat 8 to reset.

[0035] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
