[0025] Two first sliding shafts 12 correspond one-to-one with two mounting plates 3. Each mounting plate 3 has a third sliding groove 13 opened in the vertical direction. The openings of the two third sliding grooves 13 are horizontally opposite each other, and each third sliding groove 13 passes through the mounting plate 3 in the horizontal direction.

[0026] Each first slide shaft 12 is inserted into the third slide groove 13 on the corresponding mounting plate 3 and is limited and slidably engaged with the third slide groove 13 on the corresponding mounting plate 3.

[0027] Each first slide shaft 12 is fixedly provided with a square block, and each first slide shaft 12 has a directional block passing through the middle of its square block. Each square block is limited and slidably engaged with the third slide groove 13 on the mounting plate 3 corresponding to the first slide shaft 12.

[0031] Specifically, the connecting plate 16 is arranged along the width direction of the lower belt of the conveyor belt 6, and multiple horizontal limiting rods 15 are fixedly arranged on the vertical connecting plate 16 near the end face of the moving plate. Each limiting rod 15 is arranged in the conveying direction of the lower belt of the conveyor belt 6, and the multiple limiting rods 15 are evenly distributed at equal intervals along the width direction of the lower belt of the conveyor belt 6. Each limiting rod 15 passes through the moving plate and is in a limiting sliding engagement with the moving plate.

[0032] A limiting block is fixedly installed at the end of each limiting rod 15 away from the connecting plate 16.

[0037] A cleaning component for cleaning the cleaning brush 14 is installed on the connecting plate 16.

[0038] Specifically, the cleaning component includes a push plate 17, which has an inverted L-shaped cross-section and is positioned along the width of the lower belt of the conveyor belt 6. The push plate 17 includes a scraping end for scraping the cleaning surface of the cleaning brush 14, which is a horizontal plate. The push plate 17 also includes a sliding end that is slidably connected to the connecting plate 16, which is a vertical plate.

[0039] Multiple vertical sliding rods 4 are fixed to the bottom of the sliding end of the push plate 17. The multiple sliding rods 4 are evenly distributed at equal intervals along the width direction of the lower belt of the conveyor belt 6. Each sliding rod 4 is inserted downward into the connecting plate 16 and is in a limiting sliding engagement with the connecting plate 16.

[0040] A limit cap is fixedly installed at the bottom of each slide rod 4, and each limit cap is in a limiting sliding fit with the connecting plate 16.

[0041] Each slide bar 4 is fitted with a spring. One end of each spring is fixedly connected to the limit cap on the slide bar 4, and the other end is fixedly connected to the connecting plate 16.

[0042] In this embodiment, the cleaning brush 14 is used to clean the bottom surface of the conveyor belt 6, which is provided with a transmission inclined surface that abuts against the scraping end of the push plate 17.

[0043] Below the cleaning brush 14 is a collection box 20 for collecting dust and other debris.

[0044] Working principle: When using this automatic crimping device for crimping operations, the carton is placed on the conveyor belt 6, which transports the carton to below the crimping machine body 1 for crimping. After crimping is completed, the conveyor belt 6 transports the carton to the collection box 21. The above process is existing technology and will not be described in detail here.

[0045] When the conveyor belt 6 transports cartons, the bottom surface of the lower belt slides into contact with the cleaning brush 14, and the cleaning brush 14 cleans the dust off the conveying surface of the conveyor belt 6.

[0046] When the conveyor belt 6 transports cartons, the output shaft of the motor 5 synchronously drives the pinion 7 to rotate, and the pinion 7 drives the large gear 8 to rotate. During this process, the corresponding first sliding shaft 12 slides along the transmission groove relative to the large gear 8 in the following path: first sliding groove 10, first inclined groove, second sliding groove 11, second inclined groove, and finally back to the first sliding groove 10.

[0047] When the first sliding shaft 12 slides relative to the large gear 8 in the first sliding groove 10, it is in a stationary state, and the corresponding cleaning brush 14 slides in contact with the bottom surface of the lower belt of the conveyor belt 6; during this time, the conveyor belt 6 rotates once.

[0048] After the first sliding shaft 12 enters the first inclined groove relative to the large gear 8, the large gear 8 pushes the corresponding first sliding shaft 12 downwards. The first sliding shaft 12 drives the moving plate to move downwards, and the moving plate drives the cleaning brush 14 to disengage from the conveyor belt 6. During this process, the moving plate drives the limiting rod 15 to move downwards simultaneously, and the two mounting plates 3 push the two second sliding shafts 18 to move closer to the moving plate relative to the connecting plate 16. The two sliding rods 4 drive the connecting plate 16 to move closer to the moving plate, and the connecting plate 16 drives the sliding rods 4 to move closer to the moving plate. The sliding rods 4 drive the push plate 17 to move closer to the cleaning brush 14.

[0049] When the scraping end of the push plate 17 contacts the transmission inclined surface on the cleaning brush 14, the cleaning brush 14 pushes the push plate 17 upward, the push plate 17 drives the slide rod 4 to slide upward, and the slide rod 4 drives the limit cap to compress the spring.

[0050] After the scraping end of the push plate 17 disengages from the drive ramp of the cleaning brush 14, the scraping end of the push plate 17 slides into contact with the top plane of the cleaning brush 14. After the scraping end of the push plate 17 disengages from the top plane of the cleaning brush 14, the dust and other debris adhering to the cleaning brush 14 are pushed off, thereby cleaning the cleaning brush 14.

[0051] Dust and other debris fall into the collection box 20.

[0052] After the first sliding shaft 12 enters the second sliding groove 11 relative to the large gear 8, the first sliding shaft 12 stops, the moving plate stops, the cleaning brush 14 stops, the connecting plate 16 stops, and the push plate 17 stops.

[0053] After the first sliding shaft 12 enters the second inclined groove relative to the large gear 8, the large gear 8 pushes the corresponding first sliding shaft 12 upward. The first sliding shaft 12 drives the moving plate to move upward, and the moving plate drives the cleaning brush 14 closer to the conveyor belt 6. During this process, the moving plate drives the limit rod 15 to move upward synchronously, and the two mounting plates 3 push the two second sliding shafts 18 away from the moving plate relative to the connecting plate 16. The two sliding rods 4 drive the connecting plate 16 to move away from the moving plate, and the connecting plate 16 drives the sliding rods 4 to move away from the moving plate. The sliding rods 4 drive the push plate 17 to move away from the cleaning brush 14.

[0054] When the scraping end of the push plate 17 is disengaged from the cleaning brush 14, the limit cap drives the slide bar 4 to slide down under the elastic force of the spring, and the slide bar 4 drives the push plate 17 to slide back down.

[0055] Once the first sliding shaft 12 re-enters the first sliding groove 10 relative to the large gear 8, the first sliding shaft 12 comes to a stop again. At this time, the cleaning brush 14 slides in contact with the bottom surface of the conveyor belt 6 and continues the cleaning operation.

[0056] During the sliding time of the first sliding shaft 12 relative to the large gear 8 within the two inclined grooves and the second sliding groove 11, the conveyor belt 6 completes several full rotations. This ensures that the cleaning brush 14 contacts the conveyor belt 6 at the same position each time.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
