More specifically, two groups of driving mechanisms 3 can respectively drive the two groups of pulling components 2 to rotate in opposite directions, and utilize the gap between the upper and lower groups of pulling components 2 to clamp and feed the printed paper, thereby realizing material pulling. When the surface of the pulling component 2 is worn and the gap becomes larger, the distance adjusting component 5 can be used to control the upper side of the pulling component 2 to move downward, so that the gap between the two groups of pulling components 2 is reduced to meet the material pulling demand. When the pulling component 2 is severely worn, the positioning mechanism 4 can be used to release the connection between the driving mechanism 3 and the pulling component 2, so that the pulling component 2 can be quickly disassembled.

[0026] The material pulling assembly 2 includes a roller 201, a rubber layer 203 is fixedly sleeved on the surface of the roller 201, and the left and right ends of the roller 201 are fixedly connected with an insertion rod 202.

[0028] The positioning mechanism 4 includes a mounting shell 401, and the mounting shell 401 is fixedly connected to the first rotating shaft 302, the inner wall of the mounting shell 401 is rotatably connected to a double-headed screw 404, the surface of the double-headed screw 404 is threadedly connected to a positioning rod 406, and the positioning rod 406 is movably plugged with the mounting shell 401 and the first rotating shaft 302, a positioning groove 407 is provided on the surface of the insertion rod 202, and the inner wall of the positioning groove 407 is movably plugged with the end of the positioning rod 406, and the positioning mechanism 4 also includes a control component for driving the double-headed screw 404 to rotate. It should be noted that the user uses the control component to drive the double-headed screw 404 to rotate, and under the action of the thread on its surface, the positioning rod 406 will be driven to move, so that the end of the positioning rod 406 is separated from the inner wall of the positioning groove 407, and the limit on the insertion rod 202 can be released.

[0029] The control assembly includes a worm 402, and the worm 402 is rotatably connected to the mounting housing 401, a knob 403 is fixedly connected to the end of the worm 402, a worm wheel 405 is fixedly sleeved in the middle of the double-headed screw 404, and the worm wheel 405 is meshed with the worm 402.

It should be noted that when the rubber layer 203 is worn, the surface of the rubber layer 203 will become thinner, and the gap between the upper and lower groups of rubber layers 203 will become larger, affecting the transportation of paper products. At this time, the second motor 501 is operated to drive the screw rod 502 to rotate, and the slider 503 is driven to slide along the inner wall of the slide groove 504 and the surface of the guide column 505 under the action of the thread, thereby driving the first motor 301 on the upper side to descend, and the upper pulling component 2 can be driven to descend, so that the gap between the two groups of pulling components 2 becomes smaller, thereby meeting the pulling requirements.

[0031] In summary: the two groups of driving mechanisms 3 can respectively drive the two groups of pulling components 2 to rotate in opposite directions, and the gap between the upper and lower groups of pulling components 2 can be used to clamp and feed the printed paper, thereby realizing pulling. When the surface of the pulling component 2 is worn and the gap becomes larger, the distance adjusting component 5 can be used to control the upper side of the pulling component 2 to move downward, so that the gap between the two groups of pulling components 2 is reduced to meet the pulling demand. When the pulling component 2 is severely worn, the positioning mechanism 4 can be used to release the connection between the driving mechanism 3 and the pulling component 2, so that the pulling component 2 can be quickly disassembled, which achieves the effect of facilitating the quick disassembly of the pulling equipment during use, making the replacement of the pulling roller more convenient and efficient, thereby improving the convenience of equipment maintenance work.
