Obviously, the described embodiments are part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The present application embodiment discloses a pre-pressing wheel positioning mechanism for a paper separation and pressing machine, referring to Figure 1-3 , including a mounting beam 1, a rectangular slide groove is opened at the center of the mounting beam 1, and two connecting frames 2 are slidably connected to the inner wall of the rectangular slide groove, and the inner walls of the two connecting frames 2 are rotatably connected to the wire pressing wheels 3, the bottom side of the mounting beam 1 is fixedly connected to a mounting plate 4, and the right side of the mounting plate 4 is fixedly connected to a motor 5, and the output shaft of the motor 5 is fixedly connected to a bidirectional screw rod 6, and the two connecting frames 2 are spirally connected to the bidirectional screw rod 6, and the minimum spacing between the two wire pressing wheels 3 is five centimeters; by setting the bidirectional screw rod 6, when the output shaft of the motor 5 drives the bidirectional screw rod 6 to rotate, the bidirectional screw rod 6 can simultaneously drive the two connecting frames 2 to move inward or outward, thereby achieving the effect of adjusting the spacing between the two wire pressing wheels 3. Compared with manual adjustment, the mechanical setting adjustment method can make the adjustment position more accurate and reduce the generation of errors. At the same time, it can avoid the waste of time caused by repeated adjustment, and effectively improve the work efficiency.

[0020] In the present application, a measuring cylinder 7 is fixedly connected to the right side of the mounting plate 4, a measuring rod 8 is slidably connected to the inner wall of the measuring cylinder 7, the measuring cylinder 7 passes through one of the two connecting frames 2, and the measuring rod 8 is fixedly connected to the left side of one of the two connecting frames 2; by setting the measuring cylinder 7 and the measuring rod 8, when the spacing between the two crimping wheels 3 is adjusted, the measuring rod 8 will slide synchronously on the inner wall of the measuring cylinder 7, and after the spacing between the two crimping wheels 3 is adjusted, the scale lines on the measuring rod 8 are observed, and then it can be judged whether the spacing between the two crimping wheels 3 meets the requirements, thereby further improving the accuracy after adjustment.

[0021] In the present application, the top ends of the two connecting frames 2 are fixedly connected with a connecting plate 13, and the bottom sides of the two connecting plates 13 are installed with two supporting wheels 9, and the four supporting wheels 9 are in contact with the top side of the mounting beam 1; by setting the supporting wheels 9, the supporting wheels 9 can be used to provide an upward supporting force to the connecting frame 2 while reducing the friction between the connecting frame 2 and the mounting beam 1 when moving, thereby improving the smoothness of the movement.

[0022] In the present application, two guide plates 10 are fixedly connected to the top side of the mounting beam 1, the inner sides of the two guide plates 10 are fixedly connected to the same guide rod 11, and the two connecting frames 2 are both slidably connected to the guide rod 11; by setting the guide rod 11, when the connecting frame 2 moves left or right, the guide rod 11 can be used to limit the connecting frame 2, thereby ensuring that the connecting frame 2 maintains horizontal movement to avoid deviation.

[0023] In the present application, the bottom side of the mounting beam 1 is fixedly connected to a limiting plate 12, and the bidirectional screw rod 6 is rotatably connected to the left side of the limiting plate 12; by setting the limiting plate 12, the limiting plate 12 can be used to limit the right end of the bidirectional screw rod 6 to prevent the right end of the bidirectional screw rod 6 from rotating in a suspended state, thereby improving the stability of the bidirectional screw rod 6 during rotation.

[0024] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings.

The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0025] The implementation principle of the pre-pressing wheel positioning mechanism of a paper-splitting and creasing machine in the embodiment of the present application is as follows: when in use, when the output shaft of the motor 5 drives the bidirectional screw rod 6 to rotate, the bidirectional screw rod 6 can simultaneously drive the two connecting frames 2 to move inward or outward, thereby achieving the effect of adjusting the distance between the two creasing wheels 3. Compared with manual adjustment, the mechanical setting adjustment method can make the adjustment position more accurate and reduce the occurrence of errors. At the same time, it can avoid the waste of time caused by repeated adjustments, and effectively improve the work efficiency. When the distance between the two creasing wheels 3 is adjusted, the measuring rod 8 will slide synchronously on the inner wall of the measuring cylinder 7. After the distance between the two creasing wheels 3 is adjusted, the measuring rod 8 is observed. The scale lines on 8 can be used to determine whether the spacing between the two pressing wheels 3 meets the requirements, thereby further improving the accuracy after adjustment. The support wheel 9 can provide an upward supporting force to the connecting frame 2, and at the same time, it can reduce the friction between the connecting frame 2 and the mounting beam 1 when the connecting frame 2 moves, thereby improving the smoothness of movement. When the connecting frame 2 moves left or right, the guide rod 11 can be used to limit the connecting frame 2, thereby ensuring that the connecting frame 2 maintains horizontal movement and avoids offset. The limiting plate 12 can be used to limit the right end of the bidirectional screw rod 6 to prevent the right end of the bidirectional screw rod 6 from rotating in a suspended state, thereby improving the stability of the bidirectional screw rod 6 when rotating.
