Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a heating type longitudinal sealing packaging machine. Background Art

[0002] In the areas of life such as food and medicine, there are many scenarios that require packaging and sealing, and the requirements for the sealing technology of current packaging equipment are getting higher and higher. In the current technology, the sealing methods of packaging machines include longitudinal sealing and transverse sealing. In the longitudinal sealing method, the longitudinal sealing method commonly used in the prior art does not consider the performance of the roll film, and also adopts the method of first pressing by the heat sealing knife seat and then pulling the film. The roll film is pressed at high temperature and then pulled. This processing method is not suitable for PE film, which will make the PE film seal unsightly. If it is severely wrinkled, it will cause the PE film to rupture, and the integrity of the PE film after sealing cannot be guaranteed.

[0003] There is a Chinese patent with application number 2016105327023 and application date 2016.06.30. The patent name is "Longitudinal Sealing Device for Packaging Machine". Its technical solution is as follows: A longitudinal sealing device for a packaging machine includes a mounting frame, a traction mechanism, a longitudinal sealing hot knife and a longitudinal sealing cold knife arranged on the mounting frame in sequence. The longitudinal sealing hot knife includes a pair of hot knife bodies, a heater arranged on one side or both sides of the pair of hot knife bodies, and a driving mechanism for driving the pair of hot knife bodies to approach or move away from each other. The longitudinal sealing cold knife includes a pair of cold knife bodies and a cooling system arranged on one side or both sides of the pair of cold knife bodies. It is characterized in that it also includes upper and lower thermal transfer belts passing through the longitudinal sealing hot knifes and a transmission mechanism for driving the thermal transfer belts to transmit respectively.

[0004] Although the above patent can complete the sealing operation for the package, the longitudinal hot sealing knife and longitudinal cold sealing knife directly used in the above solution will cause damage to the package during sealing, and the integrity of the package cannot be guaranteed.
