Embodiment approach

[0041] As an embodiment of the present invention, the No. 1 driving unit 6 is an electromagnet 61, and the electromagnet 61 is fixedly connected to the outer ring of the heat sealing block 51; the heat sealing seat 52 is made of magnetic material, and the electromagnetic When the iron 61 is energized, a suction force is generated between the electromagnet 61 and the heat-sealing block 51 . In the present invention, the No. 1 drive unit 6 is set as an electromagnet 61, and the heat sealing seat 52 is made of magnetic material, and the right side of the top plate 2 moves downward through the suction force between the electromagnet 61 and the heat sealing seat 52, thereby reducing additional power. source, thereby improving the practicability of the heat sealing cutting machine.

[0042]As an embodiment of the present invention, the No. 2 drive unit 8 includes a rack 81, a cylinder 82 and an annular plate 83; the annular plate 83 is fixedly connected to the base 1, and the annula...

Abstract

The invention relates to the technical field of plastic bag production, in particular to a production technology for plastic bags. A heat-sealing cutting machine adopted by the production technology comprises a base, a top plate and a top base. The heat-sealing cutting machine further comprises a conveying unit, a cutting unit, a heat-sealing unit, a first driving unit and a controller. Accordingto the production technology for the plastic bags, on the one hand, through cooperation of air bags and a heating block, hot wind is blown to the plastic bags so that heat-sealing temperature of the plastic bags can be reached rapidly; meanwhile, the air bags are utilized to blow air to plastic bags heat-sealed so that the plastic bags heat-sealed can be cooled rapidly, and thus production efficiency of the plastic bags is improved; and on the other hand, a layer of polytetrafluoroethylene fabric is arranged on a heat-sealing block, generation of adhesion of the plastic bags heat-sealed to theheat-sealing block is avoided, and thus the heat-sealing effect of the plastic bags is improved.

Description

technical field [0001] The invention relates to the technical field of plastic bag production, in particular to a plastic bag production process. Background technique [0002] In the production process of the existing plastic bags, the plastic film needs to be heat-sealed. At present, heat sealing is the most common and practical bag-making method used in composite packaging materials. It uses various external conditions (such as electric heating, high-frequency voltage or ultrasonic waves, etc.) to make the sealing position of plastic bags It becomes a viscous state when heated, and with the help of a certain pressure, the two layers of film are fused into one, and the strength is maintained after cooling. Generally speaking, a good heat sealing effect depends on whether it has good heat sealing strength and undamaged appearance. [0003] There is also a patent in the prior art about a technical solution for a heat-sealing and cutting machine for plastic bags. For example...
