DETAILED DESCRIPTION

[0034] The specific embodiments described hereinbelow are intended to be illustrative only and are not intended to limit the scope of the present application. Changes can be made to the embodiments described without departing from the spirit and scope of the present application.

[0035] In the present application, unless otherwise specified, the orientation words contained in the terms such as "upper", "lower", "inner", "outer" only represent the orientation of the terms in the normal use state or the common name understood by the person skilled in the art, and should not be regarded as a limitation of the terms.

[0036] Referring to Figures 1-7 As shown in the figure, an anti-sticking PU composite conveying belt, comprising: a conveying belt body 100 mounted in a mounting rack 101, a drive motor 102 is arranged on the mounting rack 101 to drive the operation of the mounting rack 101, and a plurality of groups of continuous anti-sticking poking mechanisms 200 are arranged on the mounting rack 101 above the conveying belt body 100, and a cleaning mechanism 400 is arranged on the mounting rack 101 below the conveying belt body 100 to clean the surface of the conveying belt body 100 after conveying.

[0037] The cleaning mechanism 400 comprises a water spraying device for cleaning the surface of the conveying belt body 100, a scraping assembly 500 for scraping the surface of the conveying belt body 100, and a water absorbing assembly 600 behind the water spraying device for wiping the moisture on the surface of the conveying belt body 100.

[0038] In use, the drive motor 102 is started to drive the conveying belt body 100 in the mounting rack 101 to start running, the conveyed articles are placed on the conveying belt body 100 and move forward with the movement of the conveying belt, and in the conveying process, the plurality of groups of continuous anti-sticking poking mechanisms 200 are arranged above the conveying belt body 100 to effectively prevent the sticking between the articles and the conveying belt, ensuring the smooth and stable conveying of the articles. When the conveying belt body 100 carrying the articles passes through the poking mechanism 200 and completes the conveying task, it enters the action area of the cleaning mechanism 400, first, the water spraying device cleans the surface of the conveying belt body 100 to remove possible stains or sticking substances, then the scraping assembly 500 scrapes the surface of the conveying belt to further remove stubborn stains or residues, and finally the water absorbing assembly 600 behind the water spraying device wipes the moisture on the surface of the conveying belt body 100 to ensure the dryness and cleanliness of the surface of the conveying belt. The arrangement of the poking mechanism 200 effectively prevents the sticking between the articles and the conveying belt, ensuring the stability and continuity of the conveying, thereby improving the conveying efficiency. The water spraying device, the scraping assembly 500 and the water absorbing assembly 600 of the cleaning mechanism 400 work together to comprehensively clean and wipe the surface of the conveying belt body 100, effectively removing stains and residues to maintain the cleanliness of the conveying belt.

[0039] Referring to Figures 4-5 As shown in the figure, the poking mechanism 200 comprises an adjusting piece, a slide rod 207, a slide sleeve 208 and a poking block 209.

[0040] A plurality of groups of continuous adjusting pieces are fixedly arranged on the mounting rack 101, the bottom surface of each group of adjusting pieces is vertically fixedly provided with a slide rod 207, the slide rod 207 is detachably and slidably sleeved with a slide sleeve 208 through a fixing assembly 300, and the bottom surface of the slide sleeve 208 is fixedly provided with a poking block 209 for preventing sticking.

[0041] In the above scheme, when it is necessary to adjust the position of the block 209 according to the size or characteristics of the conveyed articles, the adjusting member is started to drive the slide rod 207 and the slide sleeve 208 to move, thereby driving the block 209 to move to the required position. The detachable sliding design of the slide sleeve 208 on the slide rod 207 makes the block 209 flexible to take for cleaning. The arrangement of the block 209 effectively reduces the long-time contact between the articles and the transmission belt at the same position, thereby reducing the risk of sticking.

[0044] In the above scheme, when it is necessary to synchronously adjust the positions of the blocks 209 in multiple groups, the servo motor 203 is started. Since the screw rods 204 in the two adjusting members are drivingly connected through the cross transmission belt 205, when one group of servo motors 203 is started, the two screw rods 204 will rotate synchronously. With the rotation of the screw rod 204, the threaded block 206 will move along the axial direction of the screw rod 204, and will keep horizontal movement due to the limitation of the limiting groove 202. This movement drives the synchronous movement of the slide rod 207, the slide sleeve 208 and the block 209. Since the screw rods 204 in the two adjusting members are drivingly connected through the cross transmission belt 205, when one group of servo motors 203 is started, the two screw rods 204 will rotate synchronously, thereby realizing the synchronous movement of the two threaded blocks 206.
