[0002] Currently, in the tobacco packaging industry, cigarette box paper needs to be transported during the printing process, and the paper feed belt is a key component that facilitates this function. It moves the paper in a prescribed direction, ensuring the continuity and efficiency of the production process. Technological advancements have significantly improved the design and manufacturing of paper feed belts, making them more durable and reliable, greatly enhancing the efficiency and quality of tobacco packaging production. However, as paper feed belts wear over time, they inevitably become worn. A worn paper feed belt provides uneven friction on the paper during transportation, making it difficult to transport the paper, thus affecting overall production efficiency.

[0003] In the related art, if the paper feed belt is replaced as a whole after being worn, there is a problem of waste of raw materials. Therefore, the worn paper feed belt is usually disassembled and the paper feed surface of the paper feed belt is ground to make the side wall of the paper feed belt smooth, which is convenient for reuse and thus reduces waste.

[0004] The above-mentioned related technologies have the following defects: during the grinding process, the paper conveyor belt generates a large amount of waste chips, which pollutes the working area and requires workers to clean the working area frequently, which reduces efficiency.

[0076] The implementation principle of the repair device for a paper conveyor belt in the embodiment of the present utility model is as follows:

[0077] After moving the vacuum cleaner 45 and making the vacuum cleaner 45 and the dust cover 44 away from the dust box 42, the annular paper feed belt 6 is wound around the driving wheel 21 and multiple driven wheels 22 to achieve preliminary limiting of the paper feed belt 6, and then the belt body of the paper feed belt 6 is passed between the two first reversing rollers 421, between the grinding wheel 41, the two second reversing rollers 422, and between the pressure wheel 32 and the two reversing wheels 31.

[0078] Then, the driving wheel 21 and the grinding wheel 41 rotate, causing the grinding wheel 41 to grind the circumference of the paper conveyor belt 6. During the grinding process of the paper conveyor belt 6, the vacuum cleaner 45 is moved so that the dust cover 44 covers the box opening of the dust collection box 42. At the same time, the vacuum cleaner 45 is started to suck away the waste chips generated during the grinding process of the paper conveyor belt 6.

[0079] After grinding the paper feed belt 6, the second slider 52 moves along the second slide rail 51 toward the driving wheel 21, causing the embossing tube 53 to press the paper feed belt 6 against the driving wheel 21. The heating element 54 heats the embossing tube 53. During the process of embossing the pattern on the paper feed surface of the paper feed belt 6, to prevent the grinding wheel 41 from grinding away the embossed pattern, the paper feed belt 6 rotates only one revolution. At the same time, the embossing tube 53 rotates, embossing a circle of pattern around the circumference of the paper feed belt 6.

[0080] Finally, the embossing tube 53, the pressing wheel 32, and the dust cover 44 are away from the repaired paper conveyor belt 6, and after the position restriction of the paper conveyor belt 6 is released, the repaired paper conveyor belt 6 is unloaded.
