The present invention relates to an adhesive tape cutting device, and more particularly, to automatically or manually cut the adhesive tape as needed, and to easily replace the adhesive tape reel wound around the tape, The present invention relates to an adhesive tape cutting device capable of always accurately cutting a tape to a certain length.

In general, the adhesive tape wound in the form of a roll is cut to a certain length to play various roles such as electrical insulation and product protection.

It was common to use such a rolled tape cut | disconnected to fixed length by manual labor.

However, there is a problem that the work efficiency is not improved by the manual work as described above.

Recently there is the Republic of Korea Utility Model Publication No. 98-0065442.

The technique of the above-mentioned publication is to form a blade insertion groove radially at a predetermined interval on the outer periphery of the spinning wheel, and to form a rotary handle coaxially with the spinning wheel to rotate the rotary handle cutting blade in conjunction with the rotation of the spinning wheel In the adhesive tape cutting device for cutting the adhesive tape wound on the outer periphery of the wheel while entering and exiting the blade insertion groove in the unit of length between the blade insertion groove, the second electric power of the primary gear coupled coaxially with the wheel A fourth gear that is transmitted through the gear and rotates in the same direction as the primary gear and a fifth gear that is meshed with the fourth gear to rotate in reverse direction are provided. Axes of the crank eccentrically to the length of the eccentric position of the fourth gear side crank and the fifth gear side crank is always coupled in the opposite direction. The bogie, in which the cutting blade is fixed in front, And a diagonal groove is formed on the rear side wall of the trolley so that the rear side thereof rises, so that the eccentric portion of the fourth gear side crank is inserted into the groove in the diagonal direction, and the middle portion of the trolley. Each of the semicircular grooves is formed so that the eccentric portions of the fifth gear side cranks are fitted to the semicircular grooves, and the T-shaped shaft support is combined thereunder.

The prior art configured as described above has the following problems.

First, when the worker rotates the rotary handle with one hand, the cutting blade enters the blade insertion groove in conjunction with the rotation of the wheel, and cuts the adhesive tape wound around the wheel to a predetermined length. Since the adhesive tape cut to a certain length is carried out, there is a problem in that there is a disadvantage in the work as well as the production amount of the adhesive tape cut to a certain length is limited.

Secondly, since the cutting blade uses a means such as a crank to feed the cutting blade into the blade insertion groove of the wheel according to the rotation angle of the rotary knob, when changing the cutting length of the adhesive tape, replace the wheel with a different diameter. In addition to changing the cutting length of the adhesive tape, the cutting blade must be replaced with the means for entering and exiting the blade insertion groove in conjunction with the rotation of the spinning wheel according to the rotation of the wheel. There was no problem.

Third, in order to install and remove the adhesive tape reel with the adhesive tape installed on the outer body, the boss must be coupled and separated, and the screw must be coupled and separated, and the outer body must be separated into two parts. There was a problem.

Fourth, since the cutting blade is interlocked with the rotation of the spinning wheel precisely in synchronization with the rotation of the wheel, the means for entering and exiting the saw insert into the blade insertion groove is composed of a plurality of gears engaged for a long time cutting device When used, the teeth of the gear are often worn or broken, there is also a problem that can not always be cut to a certain length of the adhesive tare.

An object of the present invention was created to solve the above problems, it is to be able to automatically or manually cut the adhesive tape as needed.

Another object of the present invention is to make it easy to replace the tape reel wound around the adhesive tape.

Another object of the present invention is to ensure that the adhesive tape is always cut to a certain length.
