Description

tape cutter

The present invention relates to a tape cutter, and more particularly, to a tape cutter capable of easily cutting a tape through a protruding blade and replacing the blade.

In general, a tape is a tool used to attach something to which an adhesive is applied to one side, and the tape in the form of a strip is wound in a roll form, and is used by cutting it to an appropriate length during use. These tapes are produced in various widths depending on their use, and one of the most widely used tapes is box tape used for packaging boxes.

Before the product is delivered by courier or mail, it is packed in a box or air cap, and at this time, box tape is used. Although a knife or scissors may be used to repeatedly cut the box tape to a predetermined length during packaging, it is inevitably cumbersome for workers whose main job is packaging. In order to solve this inconvenience, a tape cutter equipped with a blade capable of cutting the tape while being able to mount the tape has appeared.

Most of the tape cutters currently sold on the market are configured to attach a mounted tape to an object to be adhered to a predetermined length, and then apply a blade provided to the tape cutter to the tape and twist the wrist to cut the tape. When using such a tape cutter, it is not necessary to use a separate knife or scissors to cut the tape, but depending on the user's skill level, there are cases where the cutting is not performed properly, and when used for a long time, the user's wrist is strained.

In addition, when the blade of the tape cutter wears out due to continuous use, only the blade cannot be replaced separately, so a new tape cutter must be purchased, which wastes resources and increases the cost burden.

An object of the present invention is to provide a tape cutter capable of reducing costs while preventing waste of resources by replacing only the blade, in addition to increasing work efficiency of the user and preventing injury due to long-time use, since anyone can easily cut the tape through a protruding blade.

To achieve the above object, the tape cutter according to the present invention includes a cutter body in which a tape in the form of a roll accommodated inside is drawn out through a draw-out hole formed on a bottom surface, and a blade provided inside the front side of the draw-out hole protrudes to the outside according to a user's manipulation.

In addition, inside the cutter body, a cutting fixture coupled to the side surface of the cutter body on the front side of the received tape and pivotally rotated according to the user's operation is provided, and the cutting member is detachably fitted into the cutting fixture and can move forward and backward according to the axial rotation of the cutting fixture.

In addition, on both sides of the cutter body, moving guides are formed upward from protruding holes formed on the bottom surface of the cutter body so that blades protrude and protrude, and the cutting fixture extends from a shaft-coupled point toward between the moving guides formed on both sides of the cutter body, and includes fitting parts arranged alternately with the moving guides. It may include a blade fixing portion provided with a blade.

In addition, the fitting part may have a fitting hole into which a fixing pin part is inserted, and a replacement cover capable of being opened by having a moving guide formed therein and coupled to an upper end may be provided on one side surface of the cutter body.

In addition, the replacement cover can be opened so that the movement guide formed on the inside is positioned on the same line as the fitting hole, so that the fixing pin can be inserted into the fitting hole while being guided by the movement guide formed in the replacement cover.

According to the present invention, since the blade protrudes to the outside and cuts the drawn tape according to the user's operation, there is no need to twist the wrist to cut the tape, so anyone can easily cut the tape, and the user's work efficiency can be increased and injuries caused by prolonged use can be prevented.

In addition, since the cutting member provided with the blade can be separated from the cutter body, only the cutting member or the blade of the cutting member can be replaced when the blade wears out, thereby reducing the cost while preventing resource waste.
