Description

{Portable Tape Cutting instrument}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape cutting machine, and more particularly, to a portable tape cutting machine that can conveniently and safely perform tape pulling and cutting operations.

In general, a roll-type adhesive tape is used to package a paper box or the like. In other words, after peeling the tip attached to the tape and pulling it out, attach the leading edge to the position to be bonded and pull the tape to attach. Then, one end of the tape should be cut using scissors or a knife. When the packaging process is carried out, the tape must be peeled off one by one and a separate tool must be used, which is troublesome and dangerous.

Recently, Korean Patent Laid-Open Publication No. 10-2012-0133280 (titled "tape cutting machine") has been proposed as a solution to this problem. That is, it is proposed that a worker can work with less force during taping work and prevent the tape from moving backward even after cutting the tape, thereby preventing the tapes from sticking to each other.

However, there is a troublesome problem that it is necessary to hold the tape attached to the cutter at one end and attach it after drawing it to a certain length at the time of taping work. Moreover, there is an inconvenient problem that the direction of the cutter must be suddenly broken from the direction of the attached tape in order to cut the attached tape into the cutting edge.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a tape (T) cutter, and is a portable tape cutter having a main body 10, an operating portion 20, a lead portion 30 and a cut portion 40 as shown in FIG. The cutting device of the present invention is improved in that the tape can be automatically drawn and cut by only one holding and unfolding operation with one hand, thereby improving the convenience of the overall operation.

First, the main body 10 according to the present invention constitutes the operation part 20 to the cut part 40 as shown in FIG. 1, and guides the operator to perform an operation to perform taping work. The main body 10 is composed of a bag 11 and a mounting roller 15 as shown in Fig.

The bag 11 is formed in a dry shape having a size that can be gripped by hand, and a space for accommodating the operation portion 20 to the cut portion 40 is provided therein. In other words, the operation unit 20 is installed in the rear space, the draw-out unit 30 and the cut-out unit 40 are built in the front space, and the mounting roller 15 is built in the center space together with the tape T.

The mounting roller 15 has a diameter that can be embedded in the tape T, and the rotary shaft 15a protrudes from the center. Here, the bag 11 is formed with a c-shaped mounting groove 11a for receiving the rotary shaft 15a. That is, the mounting roller 15 can be removed from the bag 11 along the b-shaped mounting groove 11a, so that the tape T can be replaced quickly and conveniently during the work process.

Then, the operation part 20 according to the present invention is incorporated in the rear of the bag 11 as shown in Fig. 1, thereby causing an operation of pulling out and cutting the tape T. Fig. 3 and 4, the operation unit 20 includes a trigger 21 and an actuator 25.

The trigger 21 protrudes downward along the hinge at the rear of the bag 11. When the trigger 21 is gripped with the remaining fingers in the state of holding the bag 11 with the thumb and the index finger as shown in Fig. 7, the tape T is pulled out, Lt; / RTI >

The actuating body (25) engages with the trigger (21) and flows forward and backward as it projects in and out. The actuating member 25 includes a pinion 25a and a rack 25b for converting the rotational motion of the trigger 21 into a rectilinear motion. That is, the rack 25b of the trigger 21 is retracted, and when the trigger 25b is retracted, the rack 25b is advanced.

The drawer 30 according to the present invention is built in front of the bag 11 as shown in Fig. 1, and draws out the tape T to the outside. As shown in FIGS. 3 and 4, the take-out unit 30 includes a take-out roller 31 and a guide roller 35.

The take-out roller 31 is engaged with the operating body 25 in front of the bag 11 and rotates so that the tape T is drawn out. That is, the adhesive surface of the tape T is attached to the outer surface of the take-out roller 31, and then rotates along the rack 25b to take out the tape T. The take-out roller 31 is further provided with a plurality of auxiliary rollers for pressing the tape T on its upper surface.

Here, the drawing-out roller 31 is divided into a movable roller 31a and a driven roller 31b which rotate in engagement with the operating body 25 as shown in Figs. The movable roller 31a and the driven roller 31b are disposed at a predetermined interval. That is, the movable roller 31a and the driven roller 31b prevent the tape T, which is wound like a conveyor, from being straightened and curled while being pulled out.

However, when the area of adhesion between the movable roller 31a and the tape T is increased by the movable roller 31a and the driven roller 31b, the pulled-out tape T is wound around the driven roller 31b. And the driven roller 31b are connected to a plurality of strip-like drawing belts 32 for guiding drawing of the tape T on the outer surface thereof.

Therefore, the movable roller 31a and the driven roller 31b are rotated in the same direction by the drawing belt 32 as shown in Fig. 7, and the area of the adhesive is reduced, so that the drawn tape T is straightly drawn out in a straight line.

At this time, the movable roller 31a has a draw-out gear 33 which rotates in engagement with the operating body 25 at its center, and a ratchet gear 34 which is engaged with the draw-out gear 33 in one direction is formed on the inner surface. 8, when the rack 25b is retracted, the take-out gear 33 and the ratchet gear 34 are engaged with each other to pull out the tape T. When the rack 25b is advanced, (34) is shifted and interlocking is interrupted. Therefore, it is possible to cut off the operation of reversing the drawn tape T backward.

The guide roller 35 rotates so as to align the direction of the tape T drawn out in front of the drawing roller 31. As described above, the drawn tape T has a property of being wound downward due to the winding characteristic. That is, the pull-out roller 31 lifts up the tape T to be rolled upward and straightly draws it straight.

Here, it is preferable that the guide rollers 35 form teeth on the outer surface so as to reduce the area of adhesion to the tape T on the outer surface. The guide roller 35 is preferably connected to the take-out roller 31 and the transfer means 36 so as to have power for lifting the tape T upward. The transmission means 36 can be composed of a belt or a gear, which is preferably composed of a rubber belt for noise reduction.

Finally, the cutting portion 40 is built in the front of the bag 11 as shown in Fig. 1 to cut the tape T pulled out. 3 and 4, the cut portion 40 is mainly composed of a cutting cam 41 and a cutting blade 42.

The cutting cam 41 rotates by being engaged with the operating member 25 on one side between the drawing roller 31 and the guide roller 35 and the cutting blade 42 is arranged on the upper side between the drawing roller 31 and the guide roller 35 The tape T is interrupted by the housing 43 inclined at a predetermined angle and lifted and lowered along the cutting cam 41 to cut the tape T pulled out. A transfer belt 45 is rotatably interposed between the cutting cam 41 and the cutting blade 42 and the transfer belt 45 is connected to a spring 46 for imparting an elastic force in one direction.

7 and 8, when the cutting cam 41 is rotated by the advancement of the rack 25b, the cutting edge 42 is raised by the spring 46 while the restraint of the transfer table 45 is released. Conversely, when the rack 25b is retracted, the cutting cam 41 presses the transfer table 45 to its original position, and the cutting blade 42 is lowered.

Hereinafter, an operation process of the cutting machine by the taping operation according to the present invention will be described.

First, as shown in FIG. 2, after the mounting roller 15 is removed from the bag 11, the mounting roller 15 is mounted on the tape T to be used for the operation, and then the mounting roller 15 is mounted in its original position. Of course, when the initial tape T is to be mounted, it is necessary to peel off the leading end and then adhere to the outer surface of the take-out roller 31. [

When the operator grasps the trigger 21 in this state, the rack 25b is retracted to rotate the take-out roller 31 in one direction as shown in Figs. In this process, the cutting blade 42 positioned between the take-out roller 31 and the guide roller 35 is raised, and the tape T is conveyed along the take-out roller 31 and the guide roller 35, In a predetermined length.

Then, the operator grasps the drawn tape T and attaches the tape T to the tip of the package, and immediately pulls the bag 11 to the rest of the package to attach the tape T. The tape T is cut between the take-out roller 31 and the guide roller 35 while the cutter blade 42 is lowered when the trigger 21 holding the tape T is completed.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
