[Technical field to which the invention belongs]

 The present invention relates to a kind of double-sided tape dispenser.

[0002]

[Prior art]

 In general, adhesives and nails (staples) are used to bind and seal documents and envelopes in order to make them strong, and today, where speed and convenience are pursued, staplers, glues, and adhesive tapes are used. It is the main means that can be selected. Among them, the adhesive tape is most widely applied, for example, for sealing a box, fixing a movable part or an accessory, joining a packaging cover, binding a rod or a linear object, and the like. The reason is that the stapler is only used to bind paper for a long time, and it is common to see that the stapler is pen-shaped or loaded in a bottle and automatically downwards when used and overflows immediately after use. If the lid is not covered, the glue may dry, and if it is knocked down, it may leak out.If overcoated, the glue will be pushed out and sticky, the appearance will be bad, and it will be dirty easily with ash dust. This is inconvenient. On the other hand, adhesive tapes are often very convenient for operation, and roll-type tape products are clean, easy to carry, and use a tape base or dispenser. By doing so, it can be used in a simple batch operation of pulling out and cutting, and it has considerable convenience. However, these tape mounts or dispensers are generally applied only to adhesive tape having only one side coated with adhesive, and have not provided the same operational convenience to double-sided tape. This is because a so-called double-sided tape (A) (see FIG. 5) has a liner (A3) provided on the other side of the adhesive tape body (A2) coated with an adhesive on both sides. The exposed surface on one side of the tape end (A1) is attached to the adhesive portion, and the liner (A3) is toothed to expose the other adhesive surface, and the product is used for bonding. This is because it is clearly different from a general single-sided adhesive tape.

[0003]

[Problems to be Solved by the Invention] Therefore, an object of the present invention is to provide a double-sided tape dispenser which can perform the same agile operation as a single-sided tape dispenser.

A pair of main and sub pivots 11 and 12 are protruded inside the seat case 10 at an appropriate distance from each other, and a main rotation shaft 20 and a sub rotation shaft 30 are respectively provided. A ratchet ring 15 is provided separately on the case surface at the root of the main shaft 11. One guide column 13 is provided on the front side of the sheet case 10, one convex bar 14 is provided so as to protrude, one guide wheel 60 is provided, and a cutting tooth 70 is further provided at the front end edge. . One shaft groove 16 is provided on the bottom side wall of the seat case 10, and a groove 17 for fastening the cover case 80 is provided on the upper side wall, and is combined with the cover case 80. The main and sub rotary shafts 20, 30 provided on the main and sub pivots 11, 12 are engaged with each other with gears 21, 31, respectively, and when one of them rotates, the other is synchronized. Rotate. Annular elastic ratchet teeth 24 are provided at the bottom end of the main rotating shaft 20 and are combined with the ratchet ring 15 inside the seat case 10 to provide control of the non-return. Locking grooves 23 and 33 are separately provided on the shaft surfaces of the rotating shafts 22 and 32 provided on the main and auxiliary rotating shafts 20 and 30, respectively. The operating knob 40 is provided with one bearing 41 and is used to cover the tape product. The operating knob 40 is provided with a multi-piece-shaped fitting groove 43 which is divided into rings and has elasticity. When the tension of the double-sided tape A is adjusted by inverting the operation knob 40 in the opposite direction by utilizing the elasticity of the fitting groove 43 and adjusting the tension of the double-sided tape A, the main rotary shaft 20 and idle rotation can occur. An axial holding groove 51 is formed in the shaft surface of the shaft sleeve 50, and the inside thereof is also provided with a multi-piece shaped fitting groove 52 which is also split into rings and has elasticity. When the shaft sleeve 50 and the sub-rotating shaft 30 generate unequal-speed rotation by utilizing the elasticity of the fitting groove 52, idling can be generated, thereby canceling the speed difference rotation. . After the assembly of the above components, the cover case 80 was inserted into the shaft groove 16 on the bottom side wall of the seat case 10 with the fitting shaft 81 provided on the bottom side thereof, and further provided above the cover case 80. The projection 82 is engaged with the groove 17 on the upper side wall of the seat case 10 to complete one body. The exposed portion at the front end of the fuselage is covered and protected by a locking cover 90.

At the time of mounting, as shown in FIG. 3, first, a roll-shaped double-sided tape A product is tightly placed on the bearing 41 of the operation knob 40. Subsequently, the tape end A1 is pulled out, and the tape body A2 and the liner A3 at the tape end A1 are separated, the liner A3 is pulled to the shaft surface of the shaft sleeve 50, and the end of the liner A3 is held between the holding grooves 51, Subsequently, the double-sided tape is hung on the guide column 13 and bent, and the operation knob 40 and the shaft sleeve 50 are respectively set on the main rotation shaft 20 and the sub rotation shaft 30 of the seat case 10, and then manually operated. Flip the knob 40 to bring the double-sided tape A into a tensioned state. Further, the tape main body A2 hung is adhered to the guide wheel 60 provided on the convex bar 14 at the front end of the sheet case 10, and finally the cover case is closed and sealed to complete the mounting. In operation, as shown in FIG. 4, the tape body A2 is rolled out while the front inner ring 60 at the front end of the present invention is pressed and the tape body A2 is pulled out in the forward direction. As a result, the tape body A2 and the liner A3 generate different traveling directions by utilizing the bending by the guide pillars 13, and are thereby separated from each other. Separately, the interlocking of the ratchet ring 15 provided on the seat cover 10 and the annular ratchet teeth 24 at the bottom end of the main rotating shaft 20 controls the reverse rewind prevention. The gears 21 and 31 at the bottom end of the main and sub rotary shafts 20 and 30 mesh with each other to generate synchronous reverse rotation, which is used for winding and collecting the liner A3. However, when the outer diameter of the product of the double-sided tape A is reduced by use, the outer diameter of the roll formed by winding the liner A3 is increased, so that the rotation speed is inevitably fixed by the engagement of the gears 21 and 31. It differs from the main and sub rotation shafts 20 and 30 which exhibit the speed ratio. Therefore, by utilizing the annularly split and elastic multi-piece shaped fitting groove 52 provided inside the shaft sleeve 50 to generate the idling effect with the locking groove 33, the shaft sleeve 50 and the sub-rotating shaft 30 are not in contact with each other. The constant speed is canceled, so that the double-sided tape A can maintain the tension state all the time, and can run smoothly. After the guide wheel 60 attaches the tape body A2 of an appropriate length to the article, the rear end of the present invention is lifted up and the front end is pressed downward, and the cutting teeth 70 at the front edge of the seat case 10 cut the tape. And thus, it is extremely easy and agile to operate.
