DETAILED DESCRIPTION

[0027] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only 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.

[0028] like Figures 1 to 8 As shown, a single-sheet transition paper pressing mechanism comprises: an upper pressing plate 5, a guide rod 4 and a paper pressing plate 8.

[0029] A plurality of threaded holes 13 are provided inside the upper pressing plate 5, and bolts 14 are threadedly connected inside the threaded holes 13, and the bolts 14 are threadedly connected to the guide rod 4, and the bolts 14 play a role of fixing and connecting, and the bolts 14 fix the guide rod 4 to the bottom end of the upper pressing plate 5, thereby ensuring that the positioning and guiding function of the guide rod 4 is transmitted to the upper pressing plate 5, and at the same time, the bolts 14 release the threaded connection from the threaded holes 13, and the guide rod 4 can be removed from the bottom of the upper pressing plate 5, so as to facilitate the replacement of the guide rod 4;

[0030] It also includes that the guide rod 4 is provided with a plurality of limit grooves 9 in a direction perpendicular to the bottom surface of the upper pressure plate 5, the limit groove 9 is slidably connected with a limit plate 11, and a damping pad 10 is fixedly connected to one end of the top of the limit plate 11 close to the limit groove 9. When the limit plate 11 is slidably connected in the limit groove 9, the limit plate 11 limits the guide rod 4, further enhancing the stability of the guide rod 4 when sliding up and down. The damping pad 10 generates friction when sliding in the limit groove 9, and the damping pad 10 can produce a damping effect on the limit groove 9; and

[0031] The press paper 8 is located at the bottom of the upper press plate 5. A rotating groove 19 is provided inside the side end of the press paper 8 close to the guide rod 4. A plurality of pressing holes 17 are provided inside the press paper 8. A bull's eye 15 is slidably connected inside the pressing hole 17. A rotating seat 20 is rotatably connected inside the rotating groove 19. A threaded rod 7 is fixedly connected to the top of the rotating seat 20. The top of the threaded rod 7 is threadedly connected to the adjusting hole 18 provided inside the upper press plate 5. The threaded rod 7 plays the role of a connecting structure. The threaded rod 7 connects the press paper 8 and the upper press plate 5 together. The threaded rod 7 is screwed in the adjusting hole 18. The threaded rod 7 is connected by a groove, and moves up and down by rotating. When the threaded rod 7 rotates, it drives the rotating seat 20 to rotate in the rotating groove 19, and the rotating seat 20 drives the paper pressing board 8 to move up and down, so that the threaded rod 7 can adjust the height of the paper pressing board 8, and improve the applicability of the paper pressing board 8. When the paper pressing board 8 presses the paper, the bull's eye 15 presses the paper, and at the same time, the bull's eye 15 will extend into the pressing hole 17, and the bull's eye 15 further strengthens the effect of pressing the paper, thereby ensuring that the paper pressing board 8 presses the paper more firmly.

[0032] In some specific implementation schemes, a handle 6 is vertically fixed to the top center of the upper pressing plate 5, and a spring 3 is fixedly connected to the bottom surface of the upper pressing plate 5 along a direction parallel to the guide rod 4. A number of threaded holes 13 are located at both ends of the upper pressing plate 5. The threaded holes 13 completely penetrate the upper pressing plate 5 and are located at the top of the guide rod 4. The handle 6 facilitates the staff to control the upper pressing plate 5. When the paper passes through the paper pressing board 8, the staff controls the handle 6 to pull the upper pressing plate 5 upward. Before the paper is cut, the staff releases the handle 6, and the spring 3 drives the upper pressing plate 5 to move downward to press the paper. The threaded holes 13 ensure that the bolts 14 can completely connect the guide rod 4 and the upper pressing plate 5.

[0033] In some specific embodiments, a lower pressure plate 1 is provided at the bottom end of the spring 3, and the bottom end of the spring 3 is vertically fixed on the lower pressure plate 1. The side end of the lower pressure plate 1 close to the guide rod 4 is fixedly connected with a fixing seat 2. A limiting hole 12 is provided at the side end of the lower pressure plate 1 close to the guide rod 4. The guide rod 4 is slidably connected in the limiting hole 12. The spring 3 always pulls the upper pressure plate 5 downward, and the top of the lower pressure plate 1 can pass through the paper. The side end of the lower pressure plate 1 is provided with a fixing seat 2 which can be fixed on the paper production line. The guide rod 4 slides in the limiting hole 12. At the same time, when the vibration generated when the paper is cut is transmitted to the spring 3, the damping effect generated by the damping pad 10 in the above-mentioned can avoid the resonance of the spring 3.

[0034] In some specific implementation schemes, the limiting grooves 9 are distributed on both sides of the guide rod 4 with the center line of the bolt 14, and the damping pads 10 are slidably connected in the limiting grooves 9. The distribution position of the limiting grooves 9 can ensure that the limiting force on the guide rod 4 is balanced, thereby ensuring the sliding stability of the guide rod 4.

[0035] In some specific embodiments, the pressing holes 17 are evenly distributed inside the paper pressing board 8 along a direction parallel to the lower pressing plate 1. A compression spring 16 perpendicular to the paper pressing board 8 is provided inside the pressing hole 17. The compression spring 16 is located between the bull's eye 15 and the paper pressing board 8. When the bull's eye 15 extends into the pressing hole 17, the compression spring 16 applies a downward supporting force to the bull's eye 15. The compression spring 16 ensures that the bull's eye 15 has a force to press against the paper.

[0036] In some specific implementation schemes, the upper and lower ends of the compression spring 16 are fixedly connected to the bull's eye 15 and the paper pressing plate 8 respectively. The fixing method of the compression spring 16 ensures that the bull's eye 15 will not fall off from the pressing hole 17.

[0037] In order for those skilled in the art to better understand the working principle of the embodiments of the present invention, the following is an explanation in conjunction with specific application scenarios:

[0038] When the paper passes through the pressing paper 8, the staff controls the handle 6 to pull the upper pressing plate 5 upwards, and the paper moves forward on the lower pressing plate 1. Before the paper is cut, the staff releases the handle 6, and the spring 3 drives the upper pressing plate 5 to move downward. At the same time, the guide rod 4 slides in the limiting hole 12, and the upper pressing plate 5 drives the threaded rod 7 to move downward, and the threaded rod 7 drives the pressing paper 8 to move downward. When the pressing paper 8 presses the paper, the bull's eye 15 presses the paper. At the same time, the bull's eye 15 will extend into the pressing hole 17, and the compression spring 16 gives the bull's eye 15 a downward holding force. The compression spring 16 ensures that the bull's eye 15 has a force to press the paper. The bull's eye 15 further strengthens the effect of pressing the paper, thereby ensuring that the pressing paper 8 presses the paper more firmly. When the paper is cut, the paper will not be arched, thereby ensuring the cutting effect of the paper. The fixing method of the compression spring 16 ensures that the bull's eye 15 will not fall off from the pressing hole 17.

[0039] When the guide rod 4 slides in the limiting hole 12 and the limiting plate 11 is slidably connected in the limiting groove 9, the limiting plate 11 limits the guide rod 4, further enhancing the stability of the guide rod 4 when sliding up and down. The damping pad 10 generates friction when sliding in the limiting groove 9, and the damping pad 10 can produce a damping effect on the limiting groove 9. When the vibration generated when the paper is cut is transmitted to the spring 3, the damping effect generated by the damping pad 10 in the above-mentioned process can avoid the resonance of the spring 3.

[0040] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
