Description

Technical Field

[0001] The utility model relates to the technical field of heat sealing mechanisms, in particular to an adhesive tape heat sealing mechanism. Background Art

[0002] Heat-sealed bags are widely used in daily chemical product packaging, food and drug packaging and other fields. Since the heat-sealed parts of the packaging bags are most likely to leak when the products are filled, and most of the damage to the packaging bags during actual use also occurs in the heat-sealed parts, choosing appropriate heat-sealed materials and heat-sealed parameters can reduce the scrap rate of the production line and effectively improve the overall barrier properties of the packaging. Heat-pressing sealing is to heat the sealing material in some way to make it reach a viscous flow state and then pressurize it to make it sticky and sealed. It is generally completed with a heat-pressing sealing device or a heat-pressing sealing machine.

[0003] However, the heat seal of the existing packaging machine is controlled by a temperature controller to control the heat of the heating tube so that the entire heat seal is maintained at a certain temperature value. During heat sealing, the two opposite heat seals clamp the bag body and maintain it for a preset time so that the bag body is hot-melted and sealed. After the sealing is completed, the bag body is cut off from the sealing area, and then the two heat seals are separated. During the separation process, the bag body is easy to adhere to the heat seal, which is easy to cause damage to the current bag body and also affects the sealing action of the subsequent bag body.
