Description

Technical Field

[0001] The utility model relates to the technical field of sealing and cutting machines, in particular to a full-automatic sealing and cutting machine. Background Art

[0002] As we all know, the sealing and cutting machine is a fully automatic unmanned packaging machine, which is widely used in the assembly line operation of mass production packaging with high work efficiency. Heat sealing is a common packaging method. Its principle is to use a heated blade to heat plastic or other materials to a molten state and then bond them together to achieve the effect of sealed packaging. It can not only protect the packaging, but also improve the quality and appearance of the packaging. At the same time, heat sealing can also improve the packaging's water resistance, gas resistance, oil resistance and moisture resistance.

[0003] In the prior art, the heat sealing knife of the automatic sealing and cutting machine is composed of an upper blade and a lower blade. When the heights of the products to be heat-sealed are inconsistent, it is necessary to adjust the distance between the upper and lower blades. However, the knife holder is usually fixed with bolts, which is cumbersome to adjust. At the same time, the width of the blade is fixed, which results in a fixed range of edge sealing operation. When the width of the product to be heat-sealed is longer, the blade is difficult to meet the heat sealing effect. Therefore, a heat sealing knife adjustment mechanism for an automatic sealing and cutting machine is needed to meet people's needs. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content
