3 Pillow Packing Machine Triple Center Sealing Device

Abstract

The present invention relates to a triple center sealing device in a pillow packaging machine, which comprises: a plurality of film supply rollers which are provided at one side of a pillow packagingmachine, and unfold a roll film (P) to supply the same to one side; a guide former provided at the pillow packaging machine and providing a function of rolling the film (P), which is transported to the one side in a state of being unfolded by the film supply rollers, to wrap a product tightly to fit the size of the product; a central sealing portion crease forming unit which is provided at the front of the pillow packaging machine, and is operated corresponding to the operation of a driving unit while allowing a sealing portion of the film to be automatically overlapped in a multiplex zigzag shape, such that a packaging process may be performed without failure; and a coating roller which is provided on the other side of the pillow packaging machine, and cuts and seals a packaging paper being discharged. Therefore, the center sealing portion of the film is overlapped in a triple manner (double layers being overlapped three times) before being attached, such that packaging can be performed without failure. Consequently, the quality and reliability of the sealing device can be significantly improved, such that various needs of manufacturers can be satisfied, thereby imparting a good impression.

Description

technical field [0001] The embodiment of the present invention relates to the triple center seal device of the pillow packaging machine. More specifically, since the center seal part of the film is folded and pasted in triple (2 layers x 3 = 6 layers, the same below), there can be no defects. The quality and reliability of the sealing device can be greatly improved by carrying out the packaging work efficiently, so it can meet the various requirements (needs) of the manufacturer and leave a good impression. Background technique [0002] As we all know, if various types of produced products are to be automatically packaged, the products that have been packaged in basic units are put into boxes or aggregated in a certain amount in machines such as case sealers, band sealers, and tying machines. , and then if it is close to the packaging machine, it will automatically run through sensor recognition and quickly pack it out. [0003] Or when using resin film (such as: PP, PE, OP...

AI Technical Summary

Problems solved by technology

[0011] In particular, the conventional technical problem is that since the central sealing part of the film is folded into a triple zigzag shape, the occurrence rate of defective packaging is high, resulting in low work efficiency

[0012] In addition, the problem of the above-mentioned conventional technology is that when using a thin film, the film is easily torn or melted and ruptured due to overheating.

[0013] Moreover, the above-mentioned conventional technical problem is that it is impossible to maintain a good sealing state without excess film and displacement.

[0014] In addition, the above-mentioned conventional technical problem is that when using a thin film, it is impossible to complete the sealing work closely

[0015] Therefore, the problem of the conventional technology described above is that it is not possible to save a great deal of cost because thin films cannot be used.

[0016] In order to solve the above-mentioned problems, it has been developed from the following prior art documents in the past, but there is still a problem that the above-mentioned problems of the prior art cannot be solved at one fell swoop.
