Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and in particular to an installation structure for a die-cutting machine pressure plate and cutter. Background Technology

[0002] Die-cutting machines are used to cut printed materials or cardboard into specific shapes and are important equipment for post-printing packaging processing. Patent application number 202322742060.8 discloses a die-cutting mechanism for a die-cutting machine, including a top plate. Two vertical rods are fixedly connected to both sides of the lower surface of the top plate. A lifting plate is slidably connected to the surfaces of the two vertical rods. A T-shaped mounting groove is opened on the side of the lifting plate. An insert plate is inserted into the T-shaped mounting groove. A cutter is fixedly connected to the lower surface of the insert plate. A pusher structure for driving the lifting plate to move is fixedly installed in the middle of the lower surface of the top plate. Two elastic telescopic structures are fixedly connected to both sides of the lower surface of the lifting plate. By opening a T-shaped mounting groove on the side of the lifting plate and fixing the insert plate on the top of the cutter, the cutter can be quickly installed by inserting the insert plate into the T-shaped mounting groove. The cutter can also be quickly disassembled, which is convenient for daily maintenance of the cutter. However, in order to make the positioning accurate, the width of the insert plate (the dimension in the left-right direction, i.e., the length direction of the cutter) is almost equal to the width of the T-shaped mounting groove. However, the width of the insert plate is relatively large, making it difficult to align the front side of the insert plate and insert it into the T-shaped mounting groove. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an installation structure for the pressure plate and cutter of a die-cutting machine, addressing the aforementioned technical deficiencies.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an installation structure for a die-cutting machine pressure plate and a cutter, including a pressure plate and a cutter. A mounting base is provided on the lower side of the pressure plate. A first inclined surface is provided on one side of the mounting base. The first inclined surface is inclined inward from the direction of approaching to moving away from the pressure plate. Positioning plates are provided at both ends of the mounting base. A guide surface is provided on the inner side of the positioning plate away from the mounting base. The guide surface is inclined outward from the direction of approaching to moving away from the mounting base. A stud is provided on the first inclined surface. The extension direction of the stud is parallel to the extension direction of the pressure plate and perpendicular to the extension direction of the mounting base. A second inclined surface is provided on one side of the top of the cutter for cooperating with the first inclined surface. The second inclined surface is inclined outward from the direction of bottom to top. An elongated hole is provided on the second inclined surface. The stud passes through the elongated hole and is connected to a nut.

[0005] To further optimize this technical solution, a washer is provided between the nut and the cutter.

[0006] Compared with the prior art, this utility model has the following advantages: a mounting base is provided on the lower side of the pressure plate, a first inclined surface is provided on one side of the mounting base, and a second inclined surface is provided on the cutter. After the elongated hole on the cutter is fitted onto the stud on the mounting base, the nut is screwed onto the stud and tightened, so that the cutter can enter between the two positioning plates on the mounting base and the top of the cutter presses against the bottom surface of the pressure plate, thereby being fixed, making installation relatively easy.

[0011] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Detailed implementation method: combined with Figure 1-3As shown, a mounting structure for a die-cutting machine pressure plate and cutter includes a pressure plate 1 (equivalent to a lifting plate in the prior art) and a cutter 2. A mounting base 11 is provided on the lower side of the pressure plate 1, extending parallel to the length direction of the pressure plate 1. A first inclined surface 111 is provided on one side of the mounting base 11, tilting inwards (inwards means closer to the mounting base 11) from the direction of approach to the pressure plate 1. Positioning plates 112 are provided at both ends of the mounting base 11, the distance between the two positioning plates 112 being equal to the length of the cutter 2. A guide surface 113 is provided on the inner side of the positioning plate 112 at the end furthest from the mounting base 11, tilting outwards (outwards means farther from the mounting base 11) from the direction of approach to the mounting base 11. The first inclined surface 111 is inclined (in the direction of the plane of symmetry of the mounting base 11). A stud 114 is provided on the first inclined surface 111. The extension direction of the stud 114 is parallel to the extension direction of the pressure plate 1 and perpendicular to the extension direction of the mounting base 11. A second inclined surface 21 is provided on one side of the top of the cutter 2 to cooperate with the first inclined surface 111. The second inclined surface 21 is inclined outward from bottom to top ("outward" here means away from the cutter 2). An elongated hole 22 is provided on the second inclined surface 21. The width of the elongated hole 22 is slightly larger than the diameter of the stud 114. The length of the elongated hole 22 is much larger than the diameter of the stud 114. The distance between the top of the elongated hole 22 and the top of the cutter 2 is less than the distance between the top of the stud 114 and the bottom surface of the pressure plate 1. The stud 114 passes through the elongated hole 22 and is connected to the nut 4.

[0013] Furthermore, a washer 3 is provided between the nut 4 and the cutter 2. The washer 3 can protect the surface of the cutter 2 from being scratched by the nut 4 and disperse the pressure of the nut 4 on the cutter 2.

[0014] During installation, first align the elongated hole 22 with the stud 114, then slip the elongated hole 22 over the stud 114 and release. At this point, the top of the cutter 2 is a certain distance from the bottom surface of the pressure plate 1. Next, screw the nut 4 onto the stud 114 and gradually tighten it. During this process, the cutter 2 is positioned between the two positioning plates 112 along its length. As the nut 4 tightens, the cutter 2 moves upward until its top surface presses against the bottom surface of the pressure plate 1. At this point, no matter how much force is applied to the cutter 2, it will not move upward or downward relative to the positioning plates 112, and is thus firmly fixed. Because the length and width of the elongated hole 22 are both small and larger than the diameter of the stud 114, it is relatively easy to slip it over the stud 114.

[0015] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
