[0001] This utility model relates to the field of paper processing equipment technology, and in particular to a die-cutting machine. Background Technology

[0002] Figure 3 The image shows a type of self-adhesive label whose fabric needs to be cut into multiple strips. The strips are severed from the original fabric, but the backing paper remains uncut. In use, the strips are peeled off the backing paper and then applied to the desired location. This application provides a die-cutting machine for die-cutting this type of self-adhesive label. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a die-cutting machine in response to the above-mentioned technical deficiencies.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a die-cutting machine, including a frame, a motor mounted on the frame, a lower die roller rotatably connected to the frame, the lower die roller being driven by the motor, bearing seats rotatably connected to both ends of a cutter roller, the bearing seats being slidably connected to the frame, a gear at one end of the cutter roller meshing with a gear at one end of the lower die roller, support portions at both ends of the cutter roller, the diameter of the support portions being larger than the diameter of the cutter roller, a plurality of cutting blades evenly spaced on the outer surface of the cutter roller, the cutting blades including two long-side blades coaxial with the cutter roller, the central angle corresponding to the long-side blades being less than 360°, the ends of the two long-side blades being connected by short-side blades, the cutting blades being lower than the outer surface of the support portions, and also including a pressing assembly for pressing the cutter roller downwards.

[0005] To further optimize this technical solution, the clamping assembly includes a lifting plate slidably connected to the frame. Vertical pressure plates are provided on the lower surfaces of both ends of the lifting plate. The plane where the pressure plates are located is also perpendicular to the axis of the cutter roller. Two pressure rollers are rotatably connected to each pressure plate, and the two pressure rollers are respectively located on both sides of the axis of the cutter roller. Threaded cylinders are provided at both ends of the upper surface of the lifting plate. A screw is rotatably connected to the top of the frame. A handwheel is provided at the top of the screw. The threaded cylinder is threadedly connected to the screw.

[0006] To further optimize this technical solution, support rollers are rotatably connected to both sides of the frame.

[0007] This invention has the following advantages: a lower die roller is rotatably connected to the frame, and support parts are provided at both ends of the cutter roller. Multiple cutters are evenly spaced on the cutter roller, and the support parts are pressed against the lower die roller. When the motor drives the lower die roller and the cutter roller to rotate, multiple strips can be cut from the self-adhesive fabric. This device has a simple structure and high efficiency.

[0012] 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.

[0013] Detailed implementation method: combined with Figures 1-2 As shown, a die-cutting machine includes a frame 1, on which a motor 2 is mounted. A lower die roller 3 is rotatably connected to the frame 1. The lower die roller 3 is a straight roller with a cylindrical outer surface. The lower die roller 3 is driven by the motor 2. Bearing seats 5 are rotatably connected to both ends of a cutter roller 6. The bearing seats 5 are slidably connected to the frame 1. A gear at one end of the cutter roller 6 meshes with a gear at one end of the lower die roller 3. Support portions 61 are provided at both ends of the cutter roller 6, and the outer surface of the support portions 61 is cylindrical. The diameter of the support part 61 is greater than the diameter of the cutter roller 6. The outer surface of the cutter roller 6 is provided with a plurality of cutters 62 at equal intervals. Each cutter 62 includes two long-side cutters coaxial with the cutter roller 6. The central angle corresponding to the long-side cutter is less than 360°. The ends of the two long-side cutters are connected by short-side cutters. The cutter 62 is lower than the outer surface of the support part 61 (the distance between them is less than the thickness of the base paper). It also includes a pressing assembly 7 that presses the cutter roller 6 downward.

[0014] Specifically, the pressing assembly 7 includes a lifting plate slidably connected to the frame 1. Vertical pressure plates are provided on the lower surfaces of both ends of the lifting plate. The plane of the pressure plates is perpendicular to the axis of the cutter roller 6. Two pressure rollers are rotatably connected to each pressure plate, and these two pressure rollers are located on opposite sides of the axis of the cutter roller 6. Threaded cylinders are provided at both ends of the upper surface of the lifting plate. A screw is rotatably connected to the top of the frame 1, and a handwheel 71 is provided at the top of the screw. The threaded cylinders are threadedly connected to the screw. Rotating the handwheel 71 causes the pressure rollers to press down on the upper part of the support 61, thus making close contact with the lower die roller 3. At this time, the cutter 62 does not contact the lower die roller 3, thus preventing the bottom paper from being cut.

[0015] Furthermore, support rollers 4 are rotatably connected to both sides of the frame 1, and the support rollers 4 are located below the self-adhesive label to support it.

[0016] In use, the self-adhesive tape passes between the lower die roller 3 and the cutter roller 6. The motor 2 drives the lower die roller 3 and the cutter roller 6 to rotate, causing the self-adhesive tape to move relative to the frame 1. During this process, multiple strips are cut out of the fabric. This device has a simple structure and high efficiency.

[0017] 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.
