A punching machine for a double-layer air-filled film with heat-sealed conservative holes

Abstract

The invention discloses a punching machine for a double-layer inflatable film with hole edge heat sealing conservative, its structure includes a device main body, a control panel, a movable cover plate, a moving rod, a punching device, a fixed roller shaft, a receiving roller, a rotating motor. Beneficial effects: the invention utilizes the waste material to completely remove the structure, and under the action of the movable perforating needle, the film at the required perforation is completely cut off and perforated, so as to avoid the phenomenon of "broken lotus and thread connection" between the perforated waste material and the normal film, Under the action of the hole residual material clearing component, the centralized collection of waste materials in the hole is realized, and the accumulation phenomenon under the long-term operation of the equipment is avoided, which affects the normal drilling operation of the equipment. The edge of the hole after punching is conservatively heat-sealed with a certain distance, so as to avoid wrinkles caused by heat-sealing the edge of the hole when the film is tight, which makes the heat-sealing effect not good, and some parts are not completely heat-sealed, resulting in the film being made Explosion occurs when inflated.

Description

technical field [0001] The invention relates to the field of film processing equipment, more precisely, it is a punching machine for a double-layer inflatable film with holes and conservative heat sealing. Background technique [0002] When using inflatable film for packaging items, the film style is selected according to the characteristics of the required packaging items, including double-layer inflatable film, single-layer inflatable film, and multi-layer inflatable film. When processing double-layer inflatable film, In order to increase the inflatable space of the film, it is usually necessary to punch holes in order to solve the problem of large packaging volume. The state is just right (under the effect of a little loosening), when it is punching a round hole, due to the self-state of the film, when it is punched under instantaneous pressure, it is easy to appear holes in the punching place of the double-layer film There are very small wrinkles on the inner edge, and ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a punching machine with a conservative double-layer inflatable film with holes and side heat sealing, so as to solve the problem of the prior art because the film is always in a tight state when punching holes. Or the film is just in transition (under the action of a little loosening), when it is punching a round hole, due to the self-state of the film, when it is punched under instantaneous pressure, it is prone to double-layer film punching. There are very small wrinkles on the inner edge of the hole at the hole. At the same time, the hole needs to be heat-sealed while the hole is being punched. There are local incomplete heat seals in the pressing, so that when the inflatable film is inflated, there will be direct leakage due to the heat seal of the folds and the defect of explosion during the inflation process due to incomplete heat seal.
