Abstract

A hot-sealing cold-cutting bridge for automatic packing machine using film sleeves is characterized structurally by that a long sealing-cutting main body with oblique surface has a long cutting edge and two long heat-resistant plates fixed at both sides of said long cutting edge, an electrothermal wire is embedded in each heat-resistant plate, and a saw-tooth cutting edge is opposite to said long cutting edge. Its advantages are high productivity increased by 30-50%, non-adhesion to film, less electric consumption, and firm sealing.

Description

technical field [0001] The invention relates to a plastic film sealing and cutting device used on a film sealing packaging machine, in particular to a heat-sealing and cold-cut suture bridge. Background technique [0002] There is a kind of sealing and cutting problem in the film sealing packaging machine that uses plastic film to implement, such as heat-shrinkable plastic film sealing packaging machine is provided with this device. At present, the sealing and cutting devices used on plastic film sealing packaging machines are all the same, which can be called heat sealing and cutting, that is, the process of sealing and cutting is always carried out under heating. Such a device not only has low working efficiency, but also has the disadvantage that the sealing and cutting knife is always in a heated state, and the heating knife is easy to stick to the membrane, resulting in unstable sealing quality and other problems.
