Description

Technical Field

[0001] This utility model relates to the field of paper processing technology, specifically to a paper pressing device for a paper cutter. Background Technology

[0002] Paper cutters are used to handle the paper cutting needs in the later stages of printing. They have evolved from mechanical paper cutters to magnetic tape-controlled paper cutters, and further to microcomputer-controlled, color-display, fully image-guided visual processing, and computer-aided cutting systems with external programming and editing of production data. This has reduced labor intensity and made operation safer. During the cutting process, the edges of the paper may curl up or move during cutting, so a paper-pressing device is needed to press down the edges of the paper.

[0003] The existing paper pressing device mainly consists of a strip-shaped pressing plate. When pressing paper of different specifications, in order to avoid the pressing plate being too short or too long and interfering with the paper processing, it is necessary to replace the pressing plate with one of appropriate length before processing paper of different specifications, which is very inconvenient.

[0004] In view of this, there is an urgent need for a paper pressing device with an adjustable pressing plate length. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A paper pressing device for a paper cutter includes: a mounting plate and two pressing plate mechanisms. Each pressing plate mechanism includes a base plate, a pressing plate, and a limiting component. The base plate is slidably disposed on the bottom of the mounting plate, and the two base plates slide along the same straight trajectory. The pressing plate is disposed on the bottom of the base plate, and the limiting component is used to limit the sliding of the base plate.

[0008] A further feature is that,

[0009] The bottom surface of the mounting plate is provided with a straight groove, and both base plates are engaged in the straight groove.

[0010] Both sides of the linear slide groove are provided with slots, and both sides of the substrate are provided with strips. The strips on both sides of the substrate are respectively engaged in the two slots.

[0011] The top of the substrate is provided with a mounting groove, and the limiting component includes an elastic element and a top head. The top head is slidably disposed in the mounting groove, and the elastic element is used to apply an upward thrust to the top head.

[0012] The top of the top head is hemispherical, and the linear slide groove is provided with several hemispherical limiting grooves on the top of both substrates. The limiting grooves extend along the sliding direction of the substrates, and the top of the top head is engaged in the corresponding limiting groove.

[0013] The elastic element is a spring, which is disposed in the mounting groove.

[0014] The pressure plate is mounted on the base plate by bolts.

[0015] Each of the substrates has a buckle plate at one end that is far apart from the other.

[0016] A scale is provided on the top surface of the substrate.

[0017] The top of the mounting plate is provided with several mounting holes.

[0018] Several mounting holes are respectively provided on both sides and the middle of the mounting plate.

[0019] The above-described structure of this utility model can achieve the following beneficial effects:

[0020] This application can be directly installed on a paper cutter or on the lifting mechanism of a paper cutter using a mounting plate. In use, the bottom surfaces of the two pressure plates form a pressing plane to press down on the two corners of the paper on the cut side. Since the two base plates are slidably set at the bottom of the mounting plate, the distance between the two pressure plates can be reduced or increased by the movement of the two base plates towards each other or away from each other. This allows for pressing down on papers with narrow or large widths, thus facilitating the adjustment of the pressing length without having to remove the entire pressure plate device, thereby improving work efficiency.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] refer to Figure 1 The paper pressing device of the paper cutter shown includes: a mounting plate 1, two pressing plate mechanisms, each pressing plate mechanism including a base plate 2, a pressing plate 3, and a limiting component. The base plate 2 is slidably disposed at the bottom of the mounting plate 1, and the two base plates 2 slide along the same straight trajectory. The pressing plate 3 is disposed at the bottom of the base plate 2, and the top surfaces of the two pressing plates 3 are on the same horizontal plane. The limiting component is used to limit the sliding of the base plate 2.

[0030] Based on the above structure, this application can be directly installed on the paper cutter or on the lifting mechanism of the paper cutter via the mounting plate 1. In use, the bottom surfaces of the two pressure plates 3 form a pressing plane to press down on the two corners of the paper on the cutting side (by pressing down on the two corners of the paper, the paper is ensured to be flat and will not move during cutting). Since the two base plates 2 are slidably set at the bottom of the mounting plate 1, the distance between the two pressure plates 3 can be reduced or increased by the movement of the two base plates 2 towards each other or away from each other, so that the paper with a small or large width can be pressed down, thereby conveniently completing the adjustment of the pressing length and improving work efficiency.

[0031] like Figure 2 and Figure 3As shown, in order to limit and guide the movement of the two pressure plate mechanisms, the bottom surface of the mounting plate 1 is provided with a linear slide groove 11, and the two base plates 2 are both locked in the linear slide groove 11; and the two sides of the linear slide groove 11 are provided with slots 12, and the two sides of the base plate 2 are provided with locking strips 21. The locking strips 21 on both sides of the base plate 2 are respectively locked in the two slots 12. In this way, the base plate 2 can be stably fixed on the mounting plate 1 and can move linearly in the horizontal direction.

[0032] like Figures 2-4 As shown, to restrict the position of the substrate 2 relative to the mounting plate 1, a mounting groove is provided on the top of the substrate 2. The restricting component includes an elastic element 4 and a top head 5. The top head 5 is slidably disposed in the mounting groove. The elastic element 4 is used to apply an upward pushing force to the top head 5. The elastic element 4 can be a spring, which is disposed in the mounting groove. The top of the top head 5 is hemispherical. The linear slide groove 11 is provided with several hemispherical restricting grooves 13 on the top of both substrates 2. The several restricting grooves 13 extend along the sliding direction of the substrate 2. The top of the top head 5 is engaged in the corresponding restricting groove 13. Thus, when no external force is applied to the substrate 2, the top head 5 is in a position where... Under the action of the elastic element 4, the top end of the top head 5 is locked in one of the limiting grooves 13, thereby limiting the sliding of the substrate 2. When it is necessary to move the pressure plate 3, an external force is applied to the substrate 2 to push or pull the substrate 2, so that the top head 5 retracts into the mounting groove (during this process, the hemispherical top end of the top head 5 abuts against the hemispherical limiting groove 13 until it is disengaged from the limiting groove 13. That is to say, when the substrate 2 moves, the limiting component provides a certain damping. Overcoming the damping, the substrate 2 can move), so that the substrate 2 slides. When the top head 5 enters different limiting grooves 13, the distance between the two pressure plates 3 is different, thus completing the adaptive adjustment.

[0033] Further optimization involves installing the pressure plate 3 on the base plate 2 via bolts to facilitate disassembly and assembly. Different sizes of pressure plates 3 can be replaced as needed.

[0034] Further optimizations include, for example Figure 1 and Figure 3 As shown, each end of the substrate 2 that is far apart from the others is provided with a buckle plate 6, which makes it easier for the staff to operate the substrate 2; and a scale 7 is provided on the top surface of the substrate 2. When moving the substrate 2, the scale position on the substrate 2 can be observed to make the substrate 2 move more accurately.

[0035] Further optimization is that, in order to facilitate the installation of this application, the top of the mounting plate 1 is provided with a plurality of mounting holes 14, and the plurality of mounting holes 14 are respectively provided on both sides and the middle position of the mounting plate 1. In this way, multiple installation methods can be provided, and the mounting plate 1 can be installed from both sides or from the middle position.

[0036] In summary, this application can be directly installed on the paper cutter or on the lifting mechanism of the paper cutter via the mounting plate 1. During use, the bottom surfaces of the two pressure plates 3 form a pressing plane to press the two corners of the paper on the cut side. Since the two base plates 2 are slidably set at the bottom of the mounting plate 1, the distance between the two pressure plates 3 can be reduced or increased by the movement of the two base plates 2 towards each other or away from each other. This allows for pressing of papers with smaller or larger widths, thus facilitating the adjustment of the pressing length without disassembling the entire pressure plate device, thereby improving work efficiency.

[0037] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
