Two-way hot sealing and cutting mechanism

Abstract

The invention discloses a two-way hot sealing and cutting mechanism. The two-way hot sealing and cutting mechanism is applied to a pillow-type packaging machine, and comprises a rack (1) and a two-wayhot sealing and cutting device (8), wherein a one-way preliminary hot sealing device (6) is mounted on the rack and positioned on the side edge of the two-way hot sealing and cutting device; a transition conveying device (7) is mounted on the rack, and positioned between the one-way preliminary hot sealing device and the two-way hot sealing and cutting device; both the one-way preliminary hot sealing device and the two-way hot sealing and cutting device comprise frames (36); upper knife shafts (22) and lower knife shafts (23) are mounted on the frames; upper sealing knives (29) are mounted onthe upper knife shafts; lower sealing knives (30) are mounted on the lower knife shafts; the upper knife shafts and the lower knife shafts are correspondingly connected with eccentric transmission components and connected with an end sealing spindle (16) through the corresponding eccentric transmission components; and a cutter (31) is mounted on the upper sealing knife of the two-way hot sealingand cutting device. Through the two-way hot sealing and cutting mechanism disclosed by the invention, a packaging bag which contains a material can be firmly and reliably sealed through two hot sealing operations; the packaging effect is good; the packaging quality of the packaging bag is guaranteed; and the two-way hot sealing and cutting mechanism is particularly applicable to the high-speed pillow-type packaging machine.

Description

technical field [0001] The invention relates to a packaging machine, in particular to a heat-sealing and cutting mechanism especially suitable for pillow packaging machines. Background technique [0002] At present, the pillow packaging machine (i.e. pillow packaging machine) is an automatic packaging equipment suitable for medicine boards, cosmetics, food, health products or similar items. Its working process is the feeding and pushing of medicine boards or similar items, packaging film (paper) The process of releasing film conveying, items entering into the packaging film and its conveying, packaging and cutting. Its encapsulation and cutting mechanism (namely, sealing and cutting mechanism) is to simultaneously heat seal and cut the packaging film that has been equipped with articles, and is set as a process. When the pillow packaging machine is a high-speed packaging machine, the heat sealing time is short, which will cause the packaging to be sealed weakly and cause un...

AI Technical Summary

Problems solved by technology

When the pillow packaging machine is a high-speed packaging machine, the heat sealing time is short, which will cause the packaging to be sealed weakly and cause unnecessary waste, especially for the packaging of valuables.

In the film release and conveyance of the packaging film, the original coding component is installed inside the film support roller and the film winding roller group (built-in type), and its structure is relatively complicated, which will have a certain negative impact on the film release conveyance
