[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides a paper pressing structure for kraft paper production, including a box body 1 for kraft paper production: at the top of the inner cavity of the box body 1, there is a lower pressing mechanism 2 for adjustable pressing force, and on one side of the lower pressing mechanism 2, there is a pre-pressing mechanism 3 for pre-pressing and limiting;

[0028] The horizontal plate 21 in the pressing mechanism 2 is fixedly installed on the inner side wall of the box body 1. An electric push rod 22 is fixedly installed on the top of the horizontal plate 21. The output end of the electric push rod 22 is fixedly installed with a first toothed plate 23. One side of the first toothed plate 23 is engaged with a gear 26. The gear 26 is rotatably connected to the top of the box body 1.

[0029] One side of the gear 26 is engaged with a second toothed plate 27. The bottom end of the second toothed plate 27 is fixedly installed with a mounting frame 28. The inner side wall of the mounting frame 28 is rotatably connected with a pressure roller 29. Both ends of the top of the mounting frame 28 are welded with a first spring 210 and a vertical rod 211.

[0030] It can effectively realize the paper pressing process for the paper, and can adjust the spacing height according to the needs, so as to adapt to kraft papers of different thicknesses. There is no need for limit treatment, and when pressing a single piece of paper, the paper pressing effect can be improved. According to the above, the operation is simple and convenient for people to use.

[0031] A motor is fixedly installed at one end of the mounting frame 28. The output shaft of the motor is key-connected to one end of the pressure roller 29. The setting of the motor can conveniently drive the pressure roller 29 to rotate, so as to facilitate its auxiliary feeding work, and can complete the conveying and feeding operation while ensuring paper pressing.

[0032] Among them, the first spring 210 is located outside the vertical rod 211. The top end of the first spring 210 is welded to the top of the inner cavity of the box body 1. The vertical rod 211 is slidably connected to the top of the box body 1 in a penetrating manner. A limit plate is fixedly installed at the top end of the vertical rod 211.

[0033] It can ensure the stability when moving the paper pressing downward, and at the same time can play a limiting role when moving downward.

[0034] In addition, a slide bar 25 is fixedly installed on the top of the box body 1. A chute 24 is opened on the other side of the first toothed plate 23. The slide bar 25 is slidably connected with the slide bar 25. The cooperation of the slide bar 25 and the slide bar 25 can limit the first toothed plate 23, so as to ensure the stability of the up and down movement.

[0035] In addition, connecting plates 4 are fixedly installed at both ends of the inner cavity of the box body 1. An auxiliary roller 5 is rotatably connected to the inner side wall of the box body 1. The auxiliary roller 5 is located at the inner ends of the two groups of connecting plates 4. The connecting plates 4 are used to carry the kraft paper and assist its conveying. In addition, there are two groups of connecting plates 4, and the ends of the two groups of connecting plates 4 are both arc-shaped to avoid damage to the kraft paper. The auxiliary roller 5 is conducive to cooperating with the pressure roller 29 to complete the paper pressing and conveying operations.

[0036] Based on the above, the motor can not only be installed at one end of the mounting frame 28, but also can be directly installed on the outside of the box body 1 and key-connected to the end of the pressure roller 29. At this time, the feeding operation is completed by the rotation of the pressure roller 29.

[0037] When pressing the paper:

[0038] The electric push rod 22 works directly. The electric push rod 22 is used to push the first toothed plate 23 upward. At this time, the first toothed plate 23 will slide on one side of the slide bar 25. When the first toothed plate 23 moves upward, it will engage and drive the gear 26 to rotate. At this time, the gear 26 will rotate counterclockwise, and during the rotation of the gear 26, it will drive the second toothed plate 27 to move downward until the mounting bracket 28 is pushed by the second toothed plate 27 to drive the pressure roller 29 to move downward, so as to complete the paper pressing work;

[0039] When the pressure roller 29 moves downward, the first spring 210 will be stretched through the mounting bracket 28 for stretching operation. After the paper pressing is completed, the above-mentioned motor can be directly started to work. The motor can drive the pressure roller 29 to rotate or the auxiliary roller 5 to rotate according to the required installation position, ensuring that the paper can be transported while pressing the paper.

[0040] Preferably, the pre-pressing mechanism 3 includes a support component, an elastic component, and a wheel pressing component. The support component is arranged on one side of the mounting bracket 28, the elastic component is arranged on the top of the support component, and the wheel pressing component is arranged at the bottom of the elastic component.

[0041] As Figure 4 shown, the support rod 31 in the support component is fixedly installed on one side of the mounting bracket 28, and a connecting seat 32 is fixedly installed at one end of the support rod 31, playing a role of support and connection.

[0042] As Figure 4 shown, the second spring 33 in the elastic component is welded to the top of the connecting seat 32, the top of the second spring 33 is welded with a circular plate 34, and a mounting rod 35 is fixedly installed at the bottom of the circular plate 34, which is conducive to realizing the elastic connection function and ensuring a certain elasticity during wheel pressing to avoid damaging the paper.

[0043] As Figure 4 shown, the rotating rod 36 in the wheel pressing component is rotatably connected to the inside of the mounting rod 35, and a pressure wheel 37 is fixedly installed on the outside of the rotating rod 36, which is used to directly press the paper under the elastic pushing action.

[0044] When assisting in paper pressing:

[0045] First, the paper will enter from the left side of the box body 1, then be located on the top of the connecting plate 4 and the auxiliary roller 5, and then use the pressing mechanism 2 to complete the paper pressing operation on the paper in the above-mentioned manner, and at the same time, the paper feeding work can also be realized. After that, the pressed kraft paper can be wound on a pre-prepared winding device;

[0046] When the mounting frame 28 moves downward, it will synchronously drive the support rod 31 to move downward together. At this time, the support rod 31 will move the components connected to the upper and lower parts of the connecting seat 32 downward together through the connecting seat 32, until a plurality of groups of pressing wheels 37 will contact the kraft paper in advance when moving downward. At this time, the downward moving force will directly drive the pressing wheel 37 to push the mounting rod 35 through the rotating rod 36;

[0047] The mounting rod 35 will push the circular plate 34 upwards, and then stretch the second spring 33, thereby completing the elastic downward movement to perform an auxiliary limited paper pressing operation on the kraft paper to ensure its stability during paper pressing and feeding.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
