Description

Technical Field

[0001] The utility model relates to the technical field of hot pressing devices, in particular to a plastic bag hot pressing device. Background Art

[0002] Plastic bags are bags made of plastic as the main raw material. They are indispensable items in people's daily lives and are often used to hold other items. They are widely used because of their advantages of being cheap, extremely light, large in capacity, and easy to store. However, due to the disadvantages of plastic bags' extremely long degradation cycle and difficulty in handling, their production and use are banned in some countries. In the production process of plastic bags, two layers of single-layer film need to be put together to become a double-layer film, which is then hot-pressed to become the plastic bags we usually use.

[0003] However, some existing plastic bag heat pressing devices can only seal one side at a time, and the direction of the plastic bag needs to be changed manually, which increases the cost of work and reduces work efficiency. In addition, too much manual operation may cause burns to personnel, which will not only make the sealing effect poor, but also make the life safety of personnel not guaranteed. The sealing efficiency is low, and the position of the plastic bag cannot be located. Deviations are prone to occur during the edge sealing process, resulting in defects. To this end, we propose a plastic bag heat pressing device to solve the above problems. Utility Model Content
