Description

Heat shrink film packing machine

The present invention relates to a heat shrink film packaging machine, and more particularly, to a heat shrink film packaging machine for automatically packaging a heat shrink film used when the contents are contained in a container having an open top and sealing the container.

In general, in the agricultural and fisheries market, which handles large quantities of mushrooms, fruits, or aquatic products, and in the distribution market, which sells in large quantities, the contents are placed in Schiropol's containers and sealed with heat shrink film (also called wraps) to prevent them from deviating. To sell.

As described above, the conventional method that has been used to seal the container with the heat shrink film can be largely divided into a method of sealing the heat shrink film by the seller and a method of sealing using the machine.

The method of sealing by hand, which is the method of double electrons, should be sealed by using a lot of manpower, and because it is sealed using only the adhesive force of the heat shrink film, the adhesive force is weak and the contents must be easily used, which means that the waste ends and many manpower are used. There is a flaw that the product price rises.

For this reason, the latter method has been used a lot of the automatic film packing machine, which has been widely used until now, when the operator puts the containers on the machine one by one, the film is packed and packed in the machine This method also has a lot of problems because the container is removed from the machine and the new container is placed again.

In other words, the above problem is that the work speed is slow because the container must be raised after lifting up the packaging and if the work speed of the worker is slow compared to the operating speed of the machine, the film packing machine will be damaged and there is a problem for safety. .

In particular, there are various sizes of containers, and each machine has to use a different machine. Therefore, there are defects that require the installation and use of multiple machines. .

Therefore, the object of the present invention was invented to solve the above conventional problems, and was developed with the purpose of providing a heat shrink film packaging machine configured to enable continuous packaging while automatically supplying containers.

In order to achieve the above object, the present invention consists of a container input part, a container transfer part, a heat shrink film supply part and a cut part, and an adhesive part and a fusion part.

By the configuration as described above, the container placed in the input part is transferred to the container conveying part by the tight piece, and the heat shrink film supplied from the heat shrink film supply part while conveying the container in the conveying part partially seals the container. As the heat shrink film is cut in the longitudinal direction, the cut portion of the heat shrink film is adhered to the bottom surface of the container at the close contact portion, and the sealing is performed by self-adhesive force. By heating slightly, the heat-shrink film is completely fused and fixed to make a complete package.
