Description

Vinyl sealing machine for packaging {Vinyl sealing machine for packaging}

The present invention relates to a vinyl sealing machine for packaging, and more particularly, when an object to be packaged is automatically wrapped with a plastic wrapper printed with various characters, the alignment error of the sealed wrapper does not occur, and the object to be packaged with vinyl does not occur. It relates to a vinyl sealing machine for packaging that can adjust the position of the sealing part according to the size.

A mask is a health care product that covers the mouth and nose to prevent inhalation of germs and dust in the respiratory tract. In general, a mask is made of a TPE material in the form of cotton or non-woven fabric to cover the mouth and nose and attach a strap. It is a form that works across both ears, and various materials other than fabrics are used to effectively control the object to be filtered in the air. In addition, disposable masks, 2D masks, 3D masks, dental masks, cold protection masks, dustproof masks for work, etc. are diverse in types and shapes and sizes. The sizes of the masks are also different, and the sheets are sold as a single packaging unit wrapped in plastic, as well as single sheets.

The method of packing the mask with plastic is also divided into a bag type, a three-side sealing type, and a four-side sealing type.The bag type is a bag type, which is a method of opening a plastic bag with three sides blocked, inserting the mask, and then attaching the other side. As a result, the packaging work itself is a method that is performed by hand, not by machine work. In the three-sided or four-sided sealing type, two sheets of vinyl are supplied from both sides of the top and bottom, and a mask is supplied in the middle to seal the three or four sides, and most of the packaging work is carried out by mechanical work. However, on the plastic that wraps the mask, various information and pictures are printed on the packaged product's usage method, features, logos, and manufacturers. When starting the packaging, the alignment of the vinyl supplied from the top and bottom is well aligned. Even if placed, the thickness of the vinyl is very thin, so tolerances are inevitable due to differences in the degree of stretch of the pulled vinyl while continuing the packaging work, and the tolerances are accumulated and the alignment of the vinyl supplied from the upper and lower parts becomes inconsistent. Eventually, the problem of poor packaging occurs.

In addition, an expensive sealing machine cannot be used to only pack one type of mask, and in the actual field, masks of different sizes and shapes must be packaged, so it is necessary to be able to pack various types of masks with the same sealing machine. However, it is a real problem that most sealing machines currently in use do not. In addition, there is a problem in that the configuration of the mechanical device is complicated and the alignment problem described above is caused by supplying the packaging vinyl from the top and the bottom, respectively.

As for the technology related to the vinyl packaging device, technologies such as Patent Registration No. 1206623 "Vinyl Packaging Device" and Patent Registration No. 0246447 "Vinyl Automatic Packaging Device" have appeared, but the above patents form a vinyl tube and use a tubular vinyl. It can be used to pack bulky packages because it is a method to open and insert the package into the inside, and then seal both ends of the front and rear ends.However, it can be economical to pack small and thin packages such as masks. Since there is no, it is difficult to apply, and there is a problem that packages of various sizes and shapes cannot be packaged in one device.

The present invention has been conceived to solve the above problems, and an object of the present invention is to supply a single sheet of vinyl without separately supplying the upper and lower parts of the packaging vinyl, so that various characters are printed on the vinyl packaging paper When automatically packing the packaged material with a single sealing machine, alignment errors of the plastic wrapper disposed at the top and bottom to be sealed do not occur, and the position of the vinyl sealing part can be adjusted according to the size of the packaged material.
