Description

Technical Field

[0001] This utility model relates to the technical field of PET material processing equipment, specifically a fully automatic die-cutting machine for PET material. Background Technology

[0002] PET (polyethylene terephthalate) is widely used in various fields, such as packaging, electronics, and automobiles. Therefore, there are various processing equipment available for PET. A fully automatic die-cutting machine is a device used for precise cutting of PET material. It can efficiently perform mass production and ensure smooth cut edges and dimensional accuracy.

[0003] Existing fully automatic die-cutting machines often encounter the problem of finished PET sheets adhering tightly to the worktable surface after cutting. This is due to the strong adhesion between the material and the worktable. This adhesion not only increases the difficulty for operators to remove the material but also easily causes deformation of the PET material during manual peeling. Especially when processing thin PET sheets or products with finely cut contours, operators often need to pry or repeatedly bend the edges of the material to remove it, which can easily cause scratches on the product surface, burrs on the edges, or irreversible compression wrinkles, seriously affecting the appearance quality of the finished product and the yield rate of subsequent processing. Utility Model Content

Manual peeling can easily cause deformation, scratches or wrinkles of the thin material, affecting the product yield.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic die-cutting machine for PET material, comprising a laser die-cutting machine body, wherein the inner cavity of the laser die-cutting machine body is provided with a lifting assembly, the lifting assembly includes two moving rods and a guide block, a fixed plate is fixedly connected to the top of the guide block, and a plurality of sliders are slidably connected to the top of the guide block, a connecting rod is rotatably connected to one side of the fixed plate and the sliders respectively, and two first guide plates and second guide plates arranged symmetrically front and back are rotatably connected to the surface of the connecting rod, and the opposite sides of the first guide plates and the second guide plates are rotatably connected by a rotating shaft.

[0006] Furthermore, welding plates are fixedly connected to both sides of the top of the guide block, and a sliding rod is connected to one side of the welding plate.

[0009] Furthermore, a top rod is fixedly connected to the top of the fixed plate and the slider, and a perforated plate that cooperates with the top rod is fixedly connected to the top of the laser die-cutting machine body.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: A fully automatic die-cutting machine for PET material, such as... Figures 1-6As shown, the laser die-cutting machine body 1 is preferably made of PET material. The inner cavity of the laser die-cutting machine body 1 is provided with a lifting assembly 2, which includes two moving rods 21 and a guide block 210. The two ends of the moving rods 21 are rotatably connected to the inner cavity of the laser die-cutting machine body 1, and the surface of one moving rod 21 is provided with an external thread. The top of the guide block 210 is fixedly connected to a fixing plate 214, and the top of the guide block 210 is slidably connected to several sliders 215. The fixing plate 214 and the sliders 215 are respectively rotatably connected to one side of a connecting rod 216. The surface of the connecting rod 216 is rotatably connected to two first guide plates 217 and second guide plates 218 arranged symmetrically in front and behind, and the opposite sides of the first guide plates 217 and second guide plates 218 are rotatably connected by a rotating shaft.

[0026] like Figures 2-6 As shown, welding plates 212 are fixedly connected to both sides of the top of the guide block 210. A slide rod 213 is connected to one side of the welding plate 212. The surface of the slide rod 213 is fixedly connected to the inner side of the fixed plate 214. The surface of the slide rod 213 is movably connected to the inner cavity of the slider 215. A cylinder 211 is fixedly connected to one side of the guide block 210. The output end of the cylinder 211 is fixedly connected to one side of the slider 215. A top rod 219 is fixedly connected to the top of the fixed plate 214 and the top of the slider 215. A top rod 219 is fixedly connected to the top of the laser die-cutting machine body 1, which cooperates with the top rod 219 to... The perforated plate 220 is used to push the PET material cut by the laser die-cutting machine body 1 through the push rod 219 for easy removal. The front side of the laser die-cutting machine body 1 is fixedly connected to the first motor 22. The output shaft of the first motor 22 is fixedly connected to one end of the moving rod 21. The surface of the moving rod 21 is movably connected to the moving plate 23. The area where the moving plate 23 contacts the moving rod 21 is provided with a matching internal thread. The top of the moving plate 23 is equipped with a displacement sensor, so that the moving plate 23 can drive the push rod 219 to move below the perforated plate 220.

[0027] like Figures 3-6 As shown, both sides of the movable plate 23 are fixedly connected to limit plates 29. The inner side of the limit plate 29 is slidably connected to the surface of the movable plate 23. Three rotating rods 25 are provided through the inner cavity of the limit plate 29, and the area of ​​the rotating rods 25 in contact with the limit plate 29 is rotatably connected by bearings. A second motor 24 is fixedly connected to one side of the movable plate 23. The output shaft of the second motor 24 is fixedly connected to one end of the rotating rod 25. The surfaces of the three rotating rods 25 are respectively equipped with pulleys 26, and the pulleys 26 are connected by belt drive. Two push plates 27 are fixedly connected to the surface of the rotating rods 25, which are arranged symmetrically in front and behind. Push rods 28 are fixedly connected to the surface of the push plates 27, and the surface of the push rods 28 is slidably connected to the inner side of the guide block 210.

[0028] Specifically, the user lays the PET material flat on the laser die-cutting machine body 1 and performs circular or other shaped cutting operations. After cutting, the first motor 22 is started, which drives the moving rod 21 to rotate, and the moving rod 21 in turn drives the moving plate 23 to move in the front-back direction. When the moving plate 23 reaches the designated position, the cylinder 211 is activated, and the cylinder 211 pushes the slider 215 forward. During the movement, the slider 215 drives the connecting rod 216 to move synchronously, and the connecting rod 216 in turn drives the first guide plate 217 and the second guide plate 218 to perform a telescopic unfolding action, so that they can be adjusted to open and close with the connecting rod 216 fixed on the fixed plate 214 as the rotation center.

[0029] Simultaneously, the movement of slider 215 also drives the push rod 219 to move synchronously, thereby adjusting the spacing between multiple push rods 219. This design can adapt to PET materials of different widths, ensuring that the lifting mechanism accurately corresponds to the area to be picked up, improving the versatility and stability of material picking.

[0030] Subsequently, the second motor 24 is started, driving the rotating rod 25 to rotate. The rotating rod 25 drives the pulley 26 to rotate, and the pulley 26 transmits power to the other rotating rods 25 through a synchronous belt drive, achieving synchronous rotation of multiple sets of rotating rods 25. The rotating rod 25 further drives the push plate 27 to rotate, and the push plate 27 pushes the push rod 28 to move upward. The push rod 28 transmits power to the guide block 210, and finally pushes the top rod 219 to move upward as a whole, completing the lifting action.

[0031] At this time, the push rod 219 extends from under the table of the laser die-cutting machine body 1, smoothly lifting the cut PET material and removing it from the worktable. The PET material is raised to a height that is easy to operate, significantly reducing the difficulty of picking up the material.
