The conveyor belt body 1 can install and fix the connecting hollow block 22 through the cylinder 21. At the same time, the cylinder 21 can drive the connecting hollow block 22 to move up and down through its own operation. The internal rotation of the connecting hollow block 22 is connected to a first bidirectional screw 23. The outer side of the first bidirectional screw 23 is threadedly connected to two threaded blocks 24, and the two threaded blocks 24 are slidably connected to the inside of the first bidirectional screw 23. The connecting hollow block 22 can connect the two through the first bidirectional screw 23. The threaded blocks 24 play the role of connection and limitation. At the same time, the threads on both sides of the first bidirectional screw 23 are opposite.

The plates 35 are all slidably connected to the outside of the limiting rod 33, and the limiting rod 33 can limit the first limiting plate 34 and the second limiting plate 35. When the second bidirectional screw 32 is rotated, the limiting rod 33 limits the first limiting plate 34 and the second limiting plate 35, thereby driving the first limiting plate 34 and the second limiting plate 35 to move in opposite directions. When the first limiting plate 34 and the second limiting plate 35 move to a certain distance, the first limiting plate 34 and the second limiting plate 35 can not only limit the cardboard, but also limit the cardboard to a more central position.

[0029] Specifically, one side of the first limiting plate 34 and the second limiting plate 35 are fixedly connected with a connecting block 41, the internal thread of the connecting block 41 is connected with a threaded rod 42, and the lower end of the threaded rod 42 is rotatably connected with a pressing plate 43. The connecting block 41 can connect the pressing plate 43 through the threaded rod 42. At the same time, the first limiting plate 34 and the second limiting plate 35 can respectively limit the two pressing plates 43 to a certain extent. When the connecting block 41 rotates, the rotation of the connecting block 41 can drive the pressing plate 43 to move downward. When the pressing plate 43 moves downward to a certain distance, it can limit the upper part of the cardboard, thereby reducing the situation where the cardboard is warped when being transported.

[0030] Specifically, one side of the two threaded blocks 24 is fixedly connected to a connecting rod 71, one end of the connecting rod 71 is fixedly connected to a mounting block 72, the inner side of the mounting block 72 is rotatably connected to a second creasing wheel 73, the threaded block 24 can connect the second creasing wheel 73 through the connecting rod 71 and the mounting block 72, the second creasing wheel 73 and the first creasing wheel 25 are in the same horizontal plane, the second creasing wheel 73 can perform a second creasing on the cardboard that has been creasing by the first creasing wheel 25, so that the creasing marks on the cardboard can be more obvious and deeper, and it is convenient for the staff to fold the cardboard later.

[0031] Specifically, one end of the second bidirectional screw 32 is fixedly connected to the extension rod 5, one end of the extension rod 5 passes through the fixed plate 31, and the extension rod 5 is rotatably connected to the fixed plate 31. The second bidirectional screw 32 can install and fix the extension rod 5, and the setting of the extension rod 5 makes it more convenient and easy for the staff to rotate the second bidirectional screw 32 when they need to.

[0032] Specifically, a placement plate 61 is fixedly connected to one side of the hollow block 22, and a servo motor 62 is fixedly connected to the upper side of the placement plate 61.

[0033] Specifically, a collecting box 8 is provided on one side of the conveyor belt body 1. The collecting box 8 is provided on the side of the conveyor belt body 1 away from the fixed plate 31. The collecting box 8 can collect the indented cardboard, thereby facilitating the staff to uniformly handle and process the indented cardboard in the future.

[0034] The working principle and use process of the utility model: when the device is in use, the staff can adjust the positions of the first limit plate 34, the second limit plate 35 and the first creasing wheel 25 according to the width of the cardboard. When adjusting, the staff can rotate the extension rod 5 and start the servo motor 62. When the extension rod 5 rotates, it will drive the second bidirectional screw 32 to rotate, and the second bidirectional screw 32 can limit the first limit plate 34 and the second limit plate 35 through the limit rod 33 when rotating, so as to drive the first limit plate 34 and the second limit plate 35 to move in opposite directions. When the first limit plate 34 and the second limit plate 35 move to a certain distance, the first limit plate 34 and the second limit plate 35 can limit the cardboard in a relatively central position and realize the limiting of the cardboard. After that, the staff can rotate the connecting block 41 again. When the connecting block 41 rotates, it can drive the pressing plate 43 to move downward. When the pressing plate 43 moves downward to a certain distance, the limiting of the upper part of the cardboard can be realized, thereby reducing the warping of the cardboard when being conveyed.

[0035] When the servo motor 62 is in operation, it will drive the first bidirectional screw 23 to rotate. When the first bidirectional screw 23 rotates, it can drive the two first creasing wheels 25 to move in opposite directions through the opposite threads on both sides of itself and the limit of the threaded block 24 connected to the hollow block 22. When the first creasing wheel 25 moves to the position where creasing is required, the staff can turn off the operation of the servo motor 62 and move the first creasing wheel 25 down to the upper side of the cardboard through the operation of the cylinder 21. After that, the operation of the conveyor belt body 1 will drive the cardboard to move and realize the indentation of the cardboard when passing through the first creasing wheel 25 and the second creasing wheel 73. At this point, the problem that the spring will reduce its elasticity over time after long-term use can be solved, which makes the centering rod unable to effectively limit and center the cardboard due to the weakening of the spring elasticity.
