Description

Technical Field

[0001] This utility model relates to the field of polyester film die-cutting technology, specifically to a medical polyester film die-cutting device. Background Technology

[0002] Medical-grade polyester film mainly refers to films made of polyethylene terephthalate (PET) and its modified products. Currently, conventional polyester films are primarily stored in rolls. When polyester film is needed, a specified length is usually required to avoid waste. Because many polyester films are typically die-cut to a fixed length, the films used by medical personnel are generally of similar length. However, due to different usage environments, the required length of polyester film varies. Current polyester films do not readily allow for adjusting the die-cut length according to the usage environment, leading to waste from excessively long films and increasing the burden of medical waste disposal. Utility Model Content

[0003] The purpose of this invention is to solve the problem that current polyester films are not easy to adjust the die-cutting length according to the usage environment of medical staff, which leads to waste due to excessively long polyester films. This invention provides a medical polyester film die-cutting device.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: A medical polyester film die-cutting device includes a base plate, a material receiving mechanism fixedly installed on one side of the base plate, and a material pressing mechanism provided on the base plate on one side of the material receiving mechanism. A guide groove is formed on the side wall of the base plate, and a die-cutting mechanism is provided in the guide groove. A distance adjustment mechanism is fixedly installed on the side wall of the base plate, and one side of the distance adjustment mechanism is fixedly installed on the die-cutting mechanism. A pressing mechanism is fixedly installed at the rear end of the base plate.

[0005] Preferably, the material receiving mechanism includes a side support plate, one side of which is fixedly mounted on a base plate, and a drum support rod is fixedly mounted on the side wall of the side support plate. A threaded clamp rod is fixedly mounted on one end face of the drum support rod, and a limit threaded ring is screwed onto the side wall of the threaded clamp rod.

[0006] Preferably, the material pressing mechanism includes a U-shaped frame, with both ends of the U-shaped frame slidably inserted into both ends of the base plate, and connecting plates fixedly installed on both side walls of the U-shaped frame. Spring telescopic rods are fixedly installed on the lower sides of the two connecting plates, and a connecting plate is fixedly installed on one end of the spring telescopic rod. One end of the two connecting plates is fixedly installed on the base plate. A connecting rod is fixedly installed on the side wall of the U-shaped frame, and a pressing roller is slidably sleeved on the connecting rod.

[0007] Preferably, the die-cutting mechanism includes a U-shaped support plate, a base plate is fixedly installed on the side wall of the U-shaped support plate, and a die-cutting groove is opened on the upper side wall of the base plate. An electric hydraulic rod is embedded in the side wall of the U-shaped support plate, and a blade holder is fixedly installed at the lower end of the electric hydraulic rod. A die-cutting blade is detachably and fixedly installed on the blade holder.

[0008] Preferably, the distance adjustment mechanism includes a support plate with one side fixedly mounted on the side wall of the base plate, and an adjusting screw is rotatably mounted on the support plate. An adjusting hole plate is screwed onto the side wall of the adjusting screw, and one side of the adjusting hole plate is fixedly mounted on the U-shaped support plate.

[0009] Preferably, the clamping mechanism includes an L-shaped plate, one side of which is fixedly mounted on the side wall of the base plate. A sliding hole is provided on the side wall of the L-shaped plate, and a lifting rod is slidably mounted in the sliding hole. A clamping plate is fixedly mounted on one side of the lifting rod, and a return spring is fixedly mounted on the side wall of the clamping plate. One end of the return spring is fixedly mounted on the L-shaped plate.

[0010] The beneficial effects of this utility model are as follows: 1. In this utility model, by using components such as a base plate, side support plate, and roll support rod, when it is necessary to change the size of the die-cut polyester film, the roll of polyester film is first placed on the roll support rod and fixed. Then, the polyester film is passed through the lower end of the pressure roller and pressed against it. It is then aligned with the end of the base plate, and the pressure plate is used to press and fix the polyester film. At this time, the adjusting screw is rotated, which drives the adjusting hole plate and the U-shaped support plate to move. This allows the die-cutting position to be changed manually, and the size of the die-cut polyester film can be adjusted arbitrarily. This allows medical staff to die-cut according to the specific required size, which reduces the waste of polyester film and also reduces the pressure of medical waste disposal.
