Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic film die-cutting technology, specifically a plastic film die-cutting device. Background Technology
[0002] Plastic film is a thin and flexible plastic product made from high molecular polymers (such as polyethylene, polypropylene, polyvinyl chloride, etc.) through processes such as extrusion, blow molding, and casting. It has the characteristics of transparency, water resistance, moisture resistance, and flexibility, and is widely used in packaging, agriculture, industry, electronics, medicine and other fields.
[0003] Plastic films need to be cut by die-cutting equipment during the production and processing process. For example, in the prior art, Chinese Patent Publication No. CN222222797U discloses a polyethylene resin film die-cutting device. The setting of the feeding unit can control the film, which facilitates feeding and collecting, and reduces the difficulty of operation. At the same time, with the cooperation of the extrusion component and the flattening roller, the film can be flattened before cutting, which improves production efficiency and product quality.
[0004] However, existing technologies require two sets of drive structures to drive the leveling rollers up and down and left and right when performing the film leveling operation, which is relatively complicated and has poor practicality.
[0005] To address the problems mentioned above, those skilled in the art have proposed a plastic film die-cutting device. Utility Model Content
[0006] The purpose of this invention is to provide a plastic film die-cutting device to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A plastic film die-cutting device includes a processing table, on which a cutting table and a support are mounted. A first hydraulic rod is mounted on the support, and a die-cutting tool body is fixedly connected to the first hydraulic rod. The device also includes:
[0009] The movable tables are located on both sides of the processing table and are connected to the processing table through elastic components;
[0010] A film pressing assembly is disposed on both sides of the processing table and works in conjunction with the moving table to fix the plastic film.
[0011] A moving component is disposed between the moving stage and the pressing assembly to enable movement of the moving stage.
[0012] As a further embodiment of this utility model: the elastic component includes a slide groove formed on both sides of the processing table, and a slider connected to the moving table is slidably disposed in the slide groove. The slider is connected to the end of the slide groove by a first spring.
[0013] As a further embodiment of this utility model: the pressing assembly includes two lifting plates located on both sides of the processing table. Two symmetrically distributed slide rods are slidably arranged on the lifting plates. A base plate is installed at the bottom of the slide rods, and a top plate is installed at the top. A second spring is provided between the base plate and the lifting plate. A mounting frame is installed at the bottom of the base plate. A pressure roller is rotatably arranged on the mounting frame. Second hydraulic rods connected to the processing table are installed on both sides of the lifting plate.
[0014] As a further improvement of this utility model: the moving component includes actuating rods installed on both sides of the lifting plate, and inclined blocks are installed on both sides of the moving platform.
[0015] As a further improvement of this utility model: brackets are installed on both sides of the processing table, and feeding rollers and winding rollers are placed on the brackets on both sides respectively.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model places the plastic film to be die-cut on the cutting table, and then the film pressing assembly descends and cooperates with the moving table to clamp and limit the two sides of the plastic film. As the film pressing assembly continues to descend, the moving assembly drives the moving table to move and squeeze the elastic assembly, thereby straightening the plastic film on the cutting table so that the plastic film can be placed flat on the cutting table. Then, the first hydraulic rod drives the die-cutting cutter body to descend and die-cut the plastic film. The clamping and flattening of the plastic film can be completed by the descent of the film pressing assembly, and the operation is relatively simple. Attached Figure Description

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0022] Please see Figures 1-3 A plastic film die-cutting device includes a processing table 1, on which a cutting table 5 and a support 2 are mounted. A first hydraulic rod 3 is mounted on the support 2. The first hydraulic rod 3 is fixedly connected to a die-cutting tool body 4. The first hydraulic rod 3 is equipped with an external power supply device and a control device. How to control the hydraulic rod is existing technology and will not be described in detail here. The device also includes:
[0023] Movable stages 12 are located on both sides of the processing table 1, and the movable stages 12 are connected to the processing table 1 through elastic components;
[0024] A film pressing assembly is disposed on both sides of the processing table 1 and works with the moving table 12 to fix the plastic film.
[0025] A moving component is disposed between the moving stage 12 and the pressing assembly to enable the moving stage 12 to move.
[0026] This invention places the plastic film to be die-cut on the cutting table 5, then lowers the film pressing assembly and, in conjunction with the moving table 12, clamps and limits both sides of the plastic film. As the film pressing assembly continues to descend, the moving assembly drives the moving table 12 to move and squeeze the elastic assembly, thereby straightening the plastic film on the cutting table 5 so that the plastic film can be placed flat on the cutting table 5. Then, the first hydraulic rod 3 drives the die-cutting cutter body 4 to descend and die-cut the plastic film. The clamping and flattening of the plastic film can be completed by the descent of the film pressing assembly, making the operation relatively simple.
[0027] In one embodiment, the elastic component includes grooves 9 formed on both sides of the processing table 1, and a slider 10 connected to the moving table 12 is slidably disposed in the grooves 9. The slider 10 is connected to the end of the grooves 9 by a first spring 11.
[0028] Under the elastic force of the first spring 11, the slider 10 is located at one end of the slide groove 9 near the middle of the processing table 1. When the die-cutting assembly descends, it will drive the moving table 12 to move through the moving assembly, thereby pushing the slider 10 to slide along the slide groove 9 and squeezing the first spring 11. After the die-cutting assembly is reset, the slider 10 will drive the moving table 12 to reset under the elastic force of the first spring 11, so as to facilitate the next die-cutting operation.
[0029] In one embodiment, the pressing assembly includes two lifting plates 15 located on both sides of the processing table 1. Two symmetrically distributed slide rods 16 are slidably arranged on the lifting plates 15. A base plate 17 is installed at the bottom of the slide rods 16, and a top plate 19 is installed at the top. A second spring 18 is provided between the base plate 17 and the lifting plates 15. A mounting frame 20 is installed at the bottom of the base plate 17. A pressure roller 21 is rotatably arranged on the mounting frame 20. Second hydraulic rods 14 connected to the processing table 1 are installed on both sides of the lifting plates 15.
[0030] When the plastic film is placed on the cutting table 5, the lifting plate 15 is driven to descend by the second hydraulic rod 14, so that the pressure roller 21 abuts against the moving table 12 and fixes and limits the two sides of the plastic film. As the lifting plate 15 descends, the distance between the base plate 17 and the lifting plate 15 gradually decreases, so that the second spring 18 is gradually compressed. The reverse elastic force of the second spring 18 increases the squeezing force of the pressure roller 21 on the plastic film, improving the fixing effect of the plastic film. As the lifting plate 15 continues to descend, the moving component will push the moving table 12 to move. During this process, since the pressure roller 21 is rotatable, the moving table 12 can drive the plastic film to move through the friction between it and the plastic film. The plastic film can be flattened during the movement of the moving table 12 on both sides of the cutting table 5.
[0031] Furthermore, the second hydraulic rod 14 is equipped with an external power supply and control device. How to control the hydraulic rod is existing technology and will not be described in detail here.
[0032] Furthermore, the second hydraulic rods 14 on both sides of the bottom of the lifting plate 15 move synchronously through a synchronizer.
[0033] In one embodiment, the moving component includes actuating rods 22 mounted on both sides of the lifting plate 15, and inclined blocks 13 mounted on both sides of the moving platform 12.
[0034] After the pressure roller 21 has finished squeezing and fixing the plastic film, the lifting plate 15 will continue to descend, causing the trigger rod 22 to contact the inclined block 13. Through the inclined surface of the inclined block 13 and in conjunction with the trigger rod 22, the moving table 12 can be driven to move along the slide 9 to the side away from the cutting table 5. Thus, the plastic film can be pulled by the friction between the moving table 12 and the plastic film, so that the plastic film is flattened, which facilitates the die-cutting of the plastic film.
[0035] In one embodiment, brackets 6 are installed on both sides of the processing table 1, and feeding rollers 7 and winding rollers 8 are respectively placed on the brackets 6 on both sides.
[0036] The plastic film can be released by the feeding roller 7, and the die-cut plastic film can be rolled up by the winding roller 8.
[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
