Embodiment Construction

[0038] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0039] figure 1 It is the overall structure schematic diagram of the double film bag-making machine of the present invention, as figure 1 As shown, the inner layer film used in the present invention, that is, the tube film, is placed at the far right end of the machine, fixed on the air shaft in the form of a roll film, and the air shaft is repositioned on the movable frame of the first discharging device a. The frame is equipped with a constant tension control system and a photoelectric automatic centering and deviation correction system composed of a fixed frame. The film material of the inner film is sent out by the discharge motor through the synchronous belt pulley to the discharge rubber traction roller assembly. Its speed control (fine adjustment) is completed by the subsequent tension pendulum roller. The tension pendulum ro...

Abstract

The invention relates to a double-layer film bag-making machine whose inner layer is a tube film. The inner and outer films are stacked together after being discharged and conveyed by a feeding device, and then enter a folding forming device, and the folded inner and outer films enter a center seam sealing device. The center seam is sealed, and then enters the side-cutting forming device, which performs side-cutting treatment on both sides of the inner and outer layers of the film. The tube film after the side-cutting is sequentially entered into the horizontal sealing device, the cutting device, and finally forms the finished product. The side forming device includes the first tension pendulum roller mechanism that converts the intermittent movement during seam sealing into continuous movement, the side part mechanism for side part forming, and the second tension force used to convert the continuous movement into intermittent movement during side part forming Pendulum mechanism. The edge forming device of the present invention adopts a vertical structure, and the middle formwork is suspended by gravity. Actual use shows that the edge insertion effect is good, the structure is compact, and the operation is convenient.

Description

technical field [0001] The invention relates to a bag-making machine, specifically, an inner layer of a tube film made of polyethylene PE (Polyethylene), an outer layer of a sheet film made of polyethylene terephthalate PET (polyethylene terephthalate) The utility model relates to a co-extruded film or aluminum-plastic composite film, or a double-layer film bag-making machine with a composite side of paper and plastic, belonging to the field of flexible packaging bag-making machines. Background technique [0002] With the progress of society, people's awareness of environmental protection and material safety has increased, and the packaging requirements for various objects have also been continuously improved and updated. In the past, many barrels (metal barrels or wooden plastic barrels) were gradually changed into special types of soft plastic bags for transportation and recycling. Since the inner layer is PE tube film and the outer layer is PET sheet film, the market pro...
