Description

Technical Field

[0001] This utility model relates to the field of stamping and die-cutting machine technology, specifically a stamping and die-cutting machine for automatically setting PET protective film. Background Technology

[0002] In die-cutting equipment, PET protective film is made of polyethylene terephthalate as the base material, coated with acrylic or silicone adhesives. It possesses excellent adhesion, transparency, antistatic properties, and weather resistance. During die-cutting, it protects the material surface from scratches and abrasions, and also serves functions such as transfer, waste removal, and load-bearing. It is widely used in electronics, hardware, and many other industries. When die-cutting products, a layer of PET protective film needs to be placed between the product and the lower die. The purpose is to prevent the upper die's blade from passing through the product and directly contacting the lower die, thus protecting either the blade or the lower die.

[0003] However, if the upper die of a traditional die-cutting device keeps cutting at the same position on the PET protective film, it is easy to cut the PET film. Manually adjusting the position of the PET protective film is also troublesome and inconvenient. Therefore, we have proposed a punching and die-cutting machine with automatic setting of PET protective film. Utility Model Content

[0004] The purpose of this invention is to provide a PET protective film automatic setting punching and die-cutting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A PET protective film automatic stamping and die-cutting machine includes a worktable, a lower die base fixedly mounted on the top of the worktable, first support rods fixedly mounted on both sides of the worktable, a rotating shaft rotatably connected to one side of each first support rod, a transmission roller fixedly mounted on one side of each rotating shaft, limit rings fixedly mounted at both ends of each transmission roller, a fixed plate fixedly mounted on one side of each first support rod, a servo motor fixedly mounted on one side of each fixed plate, the output end of the servo motor being fixedly connected to the rotating shaft, a support plate fixedly mounted on the bottom of the worktable, and a support base fixedly mounted on the bottom of each support plate.

[0007] As a further improvement of this utility model: the bottom of the support base is fixedly provided with a support foot, and the two ends of the support plate are fixedly provided with a second support rod.

[0008] By implementing the above solution and adding support feet, the overall stability of the device is improved.

[0009] As a further embodiment of this utility model: a rotating shaft is rotatably connected to one side of the second support rod, and the second support rod is located at the bottom of the first support rod.

[0010] The above scheme allows the conveyor roller to be fixedly mounted on one side of the rotating shaft by setting a rotating shaft.

[0011] As a further improvement of this utility model: a controller is fixedly installed on one side of the support plate, and a column is fixedly installed on the top of the workbench.

[0012] The above solution allows the top plate to be fixed to the top of the columns by setting up columns.

[0013] As a further embodiment of this utility model: a top plate is fixedly installed on the top of the column, and a hydraulic cylinder is fixedly installed on the bottom of the top plate.

[0014] The above solution, by setting up a hydraulic cylinder, allows for the adjustment of the lifting and lowering of the upper mold base.

[0015] As a further embodiment of this utility model: the controller is electrically connected to the servo motor and the hydraulic cylinder, an upper mold base is fixedly installed at the bottom of the hydraulic cylinder, and a cutting blade is fixedly installed at the bottom of the upper mold base.

[0016] The above scheme uses a cutting blade to stamp and cut the product.

[0017] As a further embodiment of this utility model: the number of the transmission rollers is four, and the outer surfaces of the four transmission rollers are connected with PET protective film, which is located on the top of the lower mold base.

[0018] The above solution, by setting a PET protective film, prevents the cutting blade of the upper mold base from passing through the product on top of the lower mold base and directly contacting the lower mold base, thus protecting the cutting blade and the lower mold.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. In the operation of this PET protective film automatic setting punching and die-cutting machine, the product to be die-cut is first placed on top of the PET protective film above the lower die base. Then, the hydraulic cylinder at the bottom of the upper die base is controlled by the controller to move. Under the push of the hydraulic cylinder, the upper die base descends and the product is die-cut by the cutting blade at the bottom of the upper die base. At this time, the PET protective film at the bottom of the product prevents the cutting blade of the upper die base from passing through the product at the top of the lower die base and directly contacting the lower die base, thus protecting the cutting blade and the lower die.

[0021] 2. This PET protective film automatic setting punching and die-cutting machine, after the device has been used for a period of time, before die-cutting is required again, the controller controls the servo motor to rotate, so that the servo motor drives the transmission roller fixedly connected to it to rotate, thereby causing the PET protective film connected to the transmission roller to rotate and adjust the position of the PET protective film, preventing the PET protective film from being cut in one position continuously. The PET protective film can move cyclically, thus avoiding the cutter repeatedly cutting in one position. The above design not only improves the service life of the PET protective film, but also makes the adjustment of the PET protective film more convenient. Attached Figure Description
