Single-side hole opener for plastic film

Abstract

The invention belongs to the technical field of hole opening for plastic films, and especially relates to a single-side hole opener for a plastic film. The single-side hole opener for the plastic filmcomprises an execution element and a drive device. According to the hole opening device, cutting drilling is carried out through the sudden change of a suction gas pressure, and the surrounding of adrilling area is fixed through a low suction gas pressure, so that high drilling quality is achieved, and the phenomena of curling and the like are not easily caused. The hole opening device is divided into the drive device and the execution element, and different types of the execution elements can be changed according to the sizes of holes needing to be drilled in the plastic film; and parts connected with a drive device outer shell and a drive device inner shell in the drive device, of execution element inner shells and execution element outer shells in the various types of execution elements are the same in size, the size of a hole capable of being drilled by the execution element is decided by the size of one end away from the drive device, of each of the execution element inner shelland the execution element outer shell in the execution element, and the size of an annular blade, and the size of one end away from the drive device, of each of the execution element inner shells andthe execution element outer shells in the different types of execution elements, and the sizes of the annular blades are different separately.

Description

[0001] Technical field

[0002] The invention belongs to the technical field of opening holes in plastic films, and in particular relates to a single-side hole opening device for plastic films. Background technique

[0003] In various plastic film processing processes, for the needs of packaging, it is often necessary to perforate various plastic films, but in the existing technology, the perforations are mostly single-sided perforations, which can easily lead to uneven surface tension of plastic films. Partially curled, and punch holes vary in size.

[0004] In view of this situation, it is necessary to punch holes on both sides at the same time, but because of the double-sided punching, the weight of the equipment will be heavy, it is not easy to carry, and it needs to be fixed; For this kind of film that cannot be moved to a fixed device with double-sided effect punching, a movable device is required to punch holes; therefore, it is necessary to design a portable punching ...
