Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cutter that automatically unwinds a ring-shaped adhesive tape and cuts it into a required length.

(Prior art and its problems) Conventionally, this type of portable cutter has been used by fitting a ring-shaped cutter into a ring-shaped adhesive tape, but the cut end often sticks to the main body. ,
Therefore, when using it, it takes time to find the cut.
In addition, when the adhesive tape is carried around and used in hospitals, etc., the rolled adhesive tape is often left uncovered, leading to an unsanitary feeling, and furthermore, the cut ends are often not neatly arranged, resulting in uneven adhesive surfaces. Further, even when used continuously, there is an inconvenience such as having to make preliminary cuts to keep the ends neat and tidy before pasting.

(Means for Solving the Problems) The present invention has been researched to solve these drawbacks, and involves storing a ring-shaped adhesive tape in a case and protruding the cut end by a simple manual operation. At the same time, it is intended to simplify cutting to a required length so that the pasting work can be done cleanly and simply.

To describe the present invention in detail with reference to illustrated embodiments, the case body 1
consists of a feeding chamber 2 which can be opened and closed by a lid 2', and a drive chamber 4 having a partition wall 3 on the side of the feeding chamber 2. A shaft body 5 is protruded from the partition wall 3 of the feeding chamber 2, and a ring Adhesive tape A
A pulley-shaped adapter 6, which can be freely inserted and removed, is rotatably fitted into the center hole of the adapter 6, and at the front position of the adapter 6, a non-resistance material with elasticity such as silicone rubber with a hardness of about 30 and an uneven surface is installed. An adhesive roller 7 and a feeding roller 8 made of hard plastic with an uneven surface that contacts the non-adhesive roller rough in a pressed state are fixed to a rotating shaft 9° 9 supported on the partition wall 3, and both rotating shafts 9, The proximal end of 9 extends into the drive chamber 4 and is fixed with a drive gear 10.10, which is linked via an intermediate gear 11 to a large operating gear 12 which rotates in only one direction. be. The lower part of the operating gear 12 projects downward through a window 13 provided at the lower part of the drive chamber 4, and a protrusion 14 having a height corresponding to the protruding part of the operating gear 12 is provided at the lower part of the lid body 2.

A take-out opening 15 is provided at the front of the feeding chamber 2, and a cutting blade 16 is provided at the rim of this opening.

In the figure, 17 is a regulating plate, which includes a non-adhesive roller 7 and a feeding roller 8.
It is fitted into the tips of the rotating shafts 9, 9, and both rollers 7.8
Keep the spacing constant. This regulating plate 17 fits into a recess 18 provided on the back surface of the lid 2'. 19 is a reversal prevention pawl.

The operating gear 12 may be freely driven by a motor (not shown), and in this case, the window 13 is not required.

(Function) The present invention is realized as described above. To use this, remove the lid 2', fit the center hole of the adhesive tape A wrapped around the adapter 6, and insert the end of the adhesive tape A. is inserted between the non-adhesive roller 7 and the feeding roller 8, the lid body 2' is closed, and the operating gear 12 protruding from the bottom of the case body 1 is fitted.

By making contact with a desk or the like and pushing the entire piece forward, the adhesive tape A is unraveled and protrudes outward from the outlet 15.

This protruding end is pulled out to a required length by hand and cut with a cutting blade 16. When the intermediate gear 11 is not provided, the operating gear 12 is rotated in the opposite direction.

(Effects) As mentioned above, the case main body of the present invention consists of a feeding chamber and a driving chamber, and the rolled adhesive tape A is stored in the feeding chamber, which prevents dust from accumulating and is hygienic. The end of the adhesive tape can always be made to protrude from the outlet simply by bringing it into contact with clothing or by driving the motor.

However, the adhesive tape that is being fed out is in a curved state due to the pressure exerted by the feeding roller and the non-adhesive roller, so that it does not hang down carelessly.

Subsequent drawer work etc. can be done quickly.

Claims (1)

[Claims] The case body consists of a feeding chamber that can be opened and closed by a lid, and a drive chamber provided on the side of the feeding chamber through a partition wall.A shaft body is protruded from the partition wall of the feeding chamber to allow the adapter to rotate freely. In addition to fitting, an elastic non-adhesive roller and a feeding roller that contacts the non-adhesive roller in a pressed state are provided at the front position of the adapter, so that the adhesive tape inserted between these rollers can be freely fed out. Both rotating shafts of the non-adhesive roller and the feeding roller are rotatably driven by a driving gear in a driving chamber, and the driving gear is linked to an operating gear that rotates in only one direction, and the operating gear is freely driven manually or by a motor. A cutter for adhesive tape, which has a take-out port in front of the feed chamber and a cutting blade on the rim of the take-out port.
