Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a cutter that automatically unravels and cuts a ring-shaped adhesive tape 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 end, and when it is used in a hospital etc., the rolled adhesive tape is left uncovered, leading to an unsanitary feeling. There are inconveniences such as the cut edges are often not neat, resulting in uneven adhesive surfaces, and even when used continuously, it is necessary to pre-cut the edges to make them neat before pasting.

(Means for Solving the Problems) This invention was researched to solve these drawbacks.The present invention was developed in order to solve these drawbacks.The adhesive tape wound in a ring shape is stored in a case and the cut end is protruded by a simple manual operation. The purpose is to make it easier to cut the adhesive to the required length and to make the pasting work clean and simple.

To describe the present invention in detail with reference to the illustrated embodiment, the case body 1 has a feeding chamber 2 which can be opened and closed by a lid body 2'.
and a drive chamber 4 provided with a partition wall 3 on the side of the feeding chamber.
Therefore, a shaft body 5 is provided protruding from the partition wall 3 of the feeding chamber 2, and the center hole of the ring-shaped adhesive tape A is rotatably fitted through a removable pulley-shaped adapter 6. In the front position of the adhesive tape A, there is a non-adhesive roller 7 made of elastic material such as silicone rubber with a hardness of about 30 and having many unevenness in the axial direction on the surface, and a hard plastic with a surface formed with convexities. The feeding roller 8 that contacts only the central part of the non-adhesive roller 7 in a pressed state is connected to the case body 1.
Alternatively, the adhesive tape A is fixed to rotating shafts 9 and 9 supported on the partition wall 3, and the center portion of the adhesive tape A is pressed between these rollers 7 and 8, and the adhesive surface of the adhesive tape A is brought into contact with the non-adhesive roller 7 and sandwiched. The adhesive tape A that has been inserted can be fed out freely, and the base ends of both rotating shafts 9, 9 extend into the drive chamber 4 to which drive gears 10, 10 are fixed. It is linked to a rack type gear 12 via a pinion type gear 11 that only meshes with the rack type gear 12. The rotating shaft 13 of the pinion type gear 11 is supported in vertically long shaft holes 14, 14 provided on the wall surface of the drive chamber 4, and the rack type gear 12 is always provided with an upward rotational force by a spring 15 at the base end. The lower end of the operating rod 17, which is provided on the upper part of the drive chamber 4 so as to be vertically movable via a sliding pin 16, hits the rack gear 12, and the rack gear 12 moves against the spring 15. Rotate 12 downward.

When the pressure on the operating rod 17 is released, the rack type gear 12 is rotated upward by the spring 15, and at the same time, the pinion type gear 11 is disengaged.

A take-out opening 18 is provided at the front of the feeding chamber 2, and a cutting blade 19 is provided at the rim of this opening.

In the figure, reference numeral 20 denotes a regulating plate, which is fitted into the tips of the rotating shafts 9, 9 of the non-adhesive roller 7 and the feeding roller 8.
The distance between both rollers 7 and 8 is maintained constant. This regulating plate 20 fits into a recess 21 provided on the back surface of the lid 2'.

(Function) The present invention is realized as described above. To use it, remove the lid 2' and fit the center hole of the wound adhesive tape A onto the shaft or adapter 6.
The adhesive surface of the central portion of the end of the adhesive tape A is brought into contact with the non-adhesive roller 7 and inserted between the feeding rollers 8, the lid body 2' is closed, and the operating rod 17 is pushed downward.
As a result, the adhesive tape A is unraveled and protrudes outward from the outlet 18. This protruding end is pulled out to a required length by hand and cut with a cutting blade 19.

(Effect) As mentioned above, the case main body 1 is the feeding chamber 2.
The rolled adhesive tape A is stored in the unwinding chamber 2, which is hygienic and prevents dust from accumulating, and the end of the adhesive tape A can always be removed by simply pressing the operating rod 17. 18, and since the feeding tape A that is fed out is curved from the center by the pressure of the feeding roller 8 and the non-adhesive roller 7, it can be pulled out without carelessly hanging down. Can work quickly. Moreover, since the non-adhesive roller 7 and the feeding roller 8 are in fixed positions, the cut end of the adhesive tape A is always at the outlet 18, and can be smoothly fed out without adhering to the edge of the opening, and is not drawn into the inside.

In addition, since the central part of the adhesive tape A is pressed, when loading the adhesive tape, the adhesive side of the adhesive tape A can be appropriately positioned on the non-adhesive roller and fed out, and even if there is some misalignment, the adhesive tape will be reliably curved. The drawer can be drawn out in a closed state, and subsequent drawers can be quickly pulled out without causing the drawer to sag inadvertently. Furthermore, since it is inserted and fed out by driving the non-adhesive roller 7 and the feeding roller 8 that presses the central portion, it is compact and convenient to carry, and has a simple structure and is highly durable.
