Problems solved by technology

[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 with varying hole sizes
[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 device to solve the problem of high quality of the film that is inconvenient to move. punching problem

Embodiment Construction

[0046] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples or drawings are used to illustrate the present invention, but not to limit the scope of the present invention.

[0047] Such as figure 1 As shown, it includes the actuator 1, the drive device 2, where as figure 2 As shown, the actuator 1 is mounted on the driving device 2 by buckling, and the driving device 2 provides kinetic energy for the actuator 1; the actuator 1 can be replaced with different models according to the size of the hole to be punched on the plastic film.

[0048] The actuator inner shell 44 and the actuator outer shell 45 of the various types of actuators designed by the present invention are all the same in size as the parts where the actuator shell 19 and the actuator inner shell 21 are connected in the drive device 2. The size of the hole is determined by the s...

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 ...
