Double-layer inflating film printing machine with hole edge hot sealing conservation function

Abstract

The invention discloses a double-layer inflating film printing machine with a hole edge hot sealing conservation function. The double-layer inflating film printing machine with the hole edge hot sealing conservation function structurally comprises an equipment body, a control panel, a movable cover plate, a moving rod, a punching device, a fixing roll shaft, a material collecting roll and a rotating motor. The double-layer inflating film printing machine with the hole edge hot sealing conservation function has the beneficial effects that a film on the portion needing to be punched is thoroughly cut off and punched under the action of a movable punching pin through a thorough waste material removing structure, and the phenomenon that punching waste materials and the normal film are apparently severed but actually connected is avoided; concentrated collection of the waste materials in a hole is achieved under the action of a hole excess material removing assembly, and the condition thatan accumulation phenomenon occurs under the long-term running effect of the equipment, and then normal punching running of the equipment is influenced is avoided; and conservative hot sealing with a certain distance is conducted on the edge of the punched hole through a hole edge pressing structure, and therefore the phenomenon that wrinkles are generated when hole edge hot sealing is conducted ina film tightening state, the hot sealing effect is poor, the local portion is not hot-sealed completely, and explosion occurs when the film is inflated is avoided.

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.
