AI Technical Summary
Due to the lack of paper presses, existing paper punching machines tend to displace due to unfixed L-plate when punching.
A paper punching machine paper press is designed. By installing the paper press at the vertical plate position of the L plate and designing a slot on the vertical plate, the elastic force of the elastic metal sheet makes the sleeve press on the upper layer of the paper to fix the paper position and prevent displacement.
It effectively prevents the paper from displaced during hole punching, ensures the stability and accuracy of the hole punching process, and avoids the problem of automatic displacement of the pull-out plate leaving the side of the paper.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paper punching machines, in particular to a paper press for a paper punching machine. Background Art
[0002] Paper punching machines generally do not have a paper press, and mainly use L-plates that are pulled out and installed on both sides of the base plate to limit the position. The vertical plate of the L-plate should be moved to the side of the paper and attached to the paper to achieve paper alignment. With such a structure, the paper will still be displaced during punching because the L-plate is not fixed. Utility Model Content
[0003] The utility model aims to provide a paper punching machine paper press to solve the problem in the background art that the paper will be displaced when punching because the L-plate is not fixed.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A paper punch press comprises a paper punch base, a pull-out plate is installed on the side of the paper punch base, the outer end of the pull-out plate is vertically and integrally connected to a vertical plate, a surface of the vertical plate facing the paper punch base is provided with a card slot, a clamping movable part is movably installed on the top of the vertical plate, a sleeve is movably sleeved on the clamping movable part, an elastic metal sheet is fixedly installed on one side of the sleeve, and a card strip surface that fits in contact with the card slot is provided on the elastic metal sheet.
[0006] As a further description of the above technical solution:
[0007] The vertical plates are located on both sides of the card slot and have reserved sealing edges.
[0008] As a further description of the above technical solution:
[0009] The two ends of the sleeve are arranged in contact with the side rods of the clamped movable part.
[0010] As a further description of the above technical solution:
[0011] The elastic metal sheet comprises a first plate and a second plate, one side of the first plate is fixedly connected to the sleeve, the other side of the first plate is integrally connected to the second plate, and the clip surface is arranged on the second plate.
[0012] As a further description of the above technical solution:
[0013] The first plate width is greater than the second plate width.
[0014] As a further description of the above technical solution:
[0015] The width of the second plate is the same as the width and length of the card slot.
[0016] Compared with the prior art, the utility model provides a paper punching machine paper press having the following
[0017] Beneficial effects:
[0018] 1. In the utility model, a paper press is installed at the vertical plate position of the L plate of the existing paper punching machine, and a card slot is designed on the vertical plate to make the sleeve press on the upper layer of the paper by using the elastic force of the elastic metal sheet, so that the paper is not easily displaced;
[0019] 2. In the present invention, because the sleeve presses down on the paper, a limiting force is applied to the pull-out plate, so that the pull-out plate cannot be easily and automatically displaced away from the side of the paper. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] 1. Paper punch base; 2. Pull-out plate; 3. Vertical plate; 4. Card slot; 5. Clamping movable part; 6. Sleeve; 7. Elastic metal sheet; 8. Card strip surface. DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0026] Example:
[0027] See also Figure 1-Figure 3The utility model provides a paper press for a paper punching machine, comprising a paper punching machine base part 1, a pull-out plate 2 is pulled out and installed on the side of the paper punching machine base part 1, the outer end of the pull-out plate 2 is vertically and integrally connected to a vertical plate 3, a surface of the vertical plate 3 facing the paper punching machine base part 1 is provided with a card slot 4, a clamping movable part 5 is movably installed on the top of the vertical plate 3, a sleeve 6 is movably sleeved on the clamping movable part 5, an elastic metal sheet 7 is fixedly installed on one side of the sleeve 6, and a card strip surface 8 that fits and contacts with the card slot 4 is provided on the elastic metal sheet 7.
[0028] Specifically, Figure 2 As shown, the vertical plate 3 is located on both sides of the card slot 4 and has reserved sealing edges to facilitate paper alignment, because the card slot 4 will affect the paper alignment.
[0029] Specifically, Figure 2 As shown, both ends of the sleeve 6 are in contact with the side rods of the clamping movable member 5, so the sleeve 6 will not shake, which is convenient for pressing the paper.
[0030] Specifically, Figure 2 and Figure 3 As shown, the elastic metal sheet 7 includes a first plate and a second plate, one side of the first plate is fixedly connected to the sleeve 6, and the other side of the first plate is integrally connected to the second plate, and the clip surface 8 is arranged on the second plate. The width of the first plate is greater than the width of the second plate, and the width of the second plate is the same as the width and length of the clip slot 4, so as to facilitate the bending and fixing of the elastic metal sheet 7.
[0031] Working principle:
[0032] When in use, pull the vertical plate 3 outward according to the length of the paper, pull out the pull-out plate 2, then put the vertical plate 3 against the side of the paper, and then press the sleeve 6 on the paper, bend the elastic metal sheet 7, and snap the card strip surface 8 of the elastic metal sheet 7 into the card slot 4 of the vertical plate 3 to fix the position of the sleeve 6. The sleeve 6 presses the paper to prevent it from moving. After punching, separate the card slot 4 and the card strip surface 8 to flip open the sleeve 6.
