Embodiment Construction

[0036] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0037] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0038] This embodiment relates to a bag-making machine for processing one side of a straight-through bag. The straight-through bag has a through hole arranged through the head to the tail. The bag-making machine includes a frame. One end of the frame to the other end of the intermittent continuous horizontal feeding mechanism, and a single-side punching device for punching one side of the straight-through bag, and a welding device for welding the gas-permeable film on the single-sided hole on the straight-through bag, and also includes The gas-permeable film feeding mechanism is perpendicular to the conveying direction of the straight-through bag to form the conveying of the gas-permeabl...

Abstract

The invention provides a bag making machine for processing one side surface of a straight-through bag. The straight-through bag has a through hole which is penetrated from the head to the tail. The bag making machine comprises a rack, a feeding mechanism, a single surface perforating device, a welding device and a gas-permeable membrane feeding mechanism, wherein the feeding mechanism is arrangedon the rack and is configured to convey the straight-through bag from one end of the rack to the other end of the rack intermittently, continuously and horizontally; the single surface perforating device is used for perforating one side surface of the straight-through bag; the welding device is used for welding a gas-permeable membrane on a single surface hole of the straight-through bag; the gas-permeable membrane feeding mechanism is used for conveying the gas-permeable membrane in a direction orthogonal to the conveying direction of the straight-through bag and is configured to convey the gas permeable membrane in the welding device; and the two side surfaces of the straight-through bag are separated through a division plate arranged in the straight-through bag and a heat insulation plate connected to the division plate and arranged in the through hole in a suspension manner, and thus, the single surface hole is formed in one side surface of the straight-through bag by cutting and the gas-permeable membrane is welded on the single surface hole. The bag making machine can significantly improve the production efficiency, meanwhile can reduce the labor intensity, and has very goodpracticability.

Description

technical field [0001] The invention relates to the technical field of plastic bag processing equipment, in particular to a bag making machine. Background technique [0002] The plastic bags in the prior art are all airtight plastic bags, and when they are used for packaging articles, they cannot be used in occasions that require ventilation. For example, the traditional edible fungus bag, its ventilation mode is generally to use the sponge ventilating cover to ventilate. When in use, when the bacteria bag is filled with culture material, put a collar on the mouth of the bacteria bag, and then cover the collar with a breathable cap with a sponge for ventilation. For the bacteria bags with breathable membranes that are directly suitable for the cultivation of edible fungi, in the prior art, there are very few equipments for producing such bacteria bags, and the structure is complicated, and manual bagging and bagging operations are still required, which is labor-intensive. ...
