Description

Lap cutting device for package

The present invention relates to a wrapping wrap cutter, and more particularly, to accommodate the roll-type wrap and improve the cutting machine to cut the wrap as needed, so that the cutting of the wrap can be made neatly and the handling is easy and unnecessary. This is to save the lap.

In general, packaging wraps are used in order to prevent food from being oxidized by air contact by blocking food from air, containers containing food, various foods for delivery, foods requiring refrigeration, and the like.

Wraps sold and distributed in the market are divided into home use and commercial use made of large diameter rolls.In the case of commonly used homes, the rolls produced in roll type are wrapped by cutting saw blades applied to the packing case. After drawing to the required length, the lap is cut and used along the longitudinal direction of the saw blade.

The cutting method of the wrap using the saw blade as described above had the following problems during use.

First, the packaging case is made of a hard paper material, and the saw blade attached to it is made of a piece of metal, there is a problem that must be separated when discarded after complete use of the wrap, because the saw blade is attached to the outside during use There was a problem of not only damage to the saw blade when storing other items, but also scratches on other objects. If you grasp the packaging case with one hand and pull out the wrap with the other hand, the hand blade is often injured. There was a downside.

On the other hand, a part of the wrap sticks to the packaging case, or the overlapping wrap occurs in the process of drawing out the wrap wound up to a predetermined length in the roll form, there is a disadvantage in that the wrap is bundled and inconvenient to use. In most cases, the user ignores the overlapping part of the lap and draws out the lap again.

As described above, the saw blade attached to the packaging case for one-time use is mostly discarded because it is unavoidable.

In view of the above, in recent years, a roll type wrap that is commercially available has been purchased separately and placed in a case, and a sliding groove is provided on the cover side while the cover is covered. There is also a product in which a blade is provided at the lower part of the lever to cut the wrap drawn out between the case and the cover by horizontal movement of the lever.

However, the cutting of the wrap was inconvenient because the cutting should be done while pressing the blade and moving horizontally (to the length corresponding to the width of the wrap).

Such products should be unscrewed and drawn out to the required length again, but after cutting the blade, the wrap may be rolled back into roll form. There was an inconvenience.

The present invention has been made in order to solve the above problems, by improving the locking device installed on the door at the same time giving the operating shaft rotation and forward operation that is operated as the action of hydraulic pressure to ensure stable locking and unlocking from the main body side hook of the device The purpose is to enable the installation of the doors of various industrial equipment for high temperature and high pressure that require airtight, as well as the general door lock.

According to the present invention for achieving the above object, the upper portion is opened to accommodate the wrap wound in a roll type, a fixed shaft for inserting and supporting both ends of the wrap on both sides is provided to be movable from the side, inside the upper side of the side A case body having a fixing groove jaw corresponding thereto and a hinge piece from the case body are installed to be rotatable. A coupling piece is formed at both bottoms to be elastically supported by the case groove side fixing groove jaw, and the wrap is cut in the longitudinal direction. In the packaging wrap cutter consisting of a cover provided with a cutting member for

The upper side of the case main body is formed in the protruding in the longitudinal direction to support the bottom surface of the drawn wrap is integrally formed protruding, while the support tape is attached to the first tape for temporarily attaching the wrap before cutting the wrap Is attached, the cutting member is fixed to the saw blade vertically embedded in the bottom surface of the cover so as to correspond between the case body side support jaw, the pressure jaw to press the upper part of the wrap on the back side of the support jaw on the saw blade side The protrusion is formed, and the pressing jaw is achieved by providing a wrapping wrap cutter with a second tape attached to support the upper portion of the wrap drawn out horizontally in the case body when cutting the wrap.

The wrapping wrap cutter according to the present invention draws the wrap received from the case body to a predetermined length and is placed in the upper part of the two support jaws provided on the main body side, the first tape provided on the support jaw and the second tape provided on the cover side pressure jaw are provided. By keeping the lap seated on the base in a non-flowing tension and then simply closing the lid, the saw blade perpendicular to the inside cuts the lap at once, so that the cutting of the lap can be simplified. As such, the wraps can be prevented from sticking to each other, and the saw blade is always located inside the cover, so that the wrap cutter can be safely handled.

Hereinafter, the configuration of the present invention with reference to the accompanying drawings in more detail.
