Description

Adhesive Tape Cutting Device

The present invention relates to an adhesive tape cutting device for manually rotating adhesive tape cutting device so that the adhesive tape wound on the spinning wheel is cut out to a certain length when the handle is turned.

Conventional adhesive tape cutting device is a cutting device for cutting by rotating the rollers with a plurality of blades synchronously with the spinning wheel, or when the spinning wheel is rotated by attaching a ratchet wheel to the side of the spinning wheel Cutting device which pushes the blade between the teeth when the blade comes between the teeth and cuts the tape. The former is the spinning wheel because the proportionality of the blade and roller is not proportional to the driving gear Since the blade insertion groove 32 of the blade should be wide, the drawback 35 for removing the tape is relatively narrow to compensate for the narrowing, and thus the length of the cut tape is longer than necessary. The latter has a high load due to friction between the blade and the teeth of the ratchet wheel during rotation. There is a "pop" "pop" noisy problems when you go into.

In order to solve the above problems, the cutting blade is inserted into the blade insertion groove of the wheel by a parabolic and shio operation to cut the adhesive tape and at the same time along with the rotational direction of the wheel, the blade inserts the groove. By deviating from the wheel, the rotational synchronous operation of the wheel and blade is precise, the blade insertion groove is narrow, the outer diameter of the wheel can be made small, and because only one blade is used, the operation is smooth and the assembly is easy.

Hereinafter, described in detail by the accompanying drawings as follows.

Bosses 215, 225 formed to secure two chassis plates 21, 22, which are symmetrical to each other, as shown in the exploded view of FIG. ) Face each other and fasten with screws (71) in parallel to each other, and the tape guide roller (13) horizontally laid on the projection (217) freely rotated and placed of the placed plate (21), (22) A reel hook 216 was formed to protrude from the rear end of the tape reel 12 by rotating the shaft of the tape reel 12, and a radially formed spinning wheel 31 was formed at a predetermined interval on the outer circumference of the blade insertion groove. The shaft tube 36 of the spinning wheel 31 penetrates the shaft 411 of the primary gear 41 in the outer wall of the through shaft hole 211 formed between the strabismus plates 21 and 22 and is formed in the upper front side of the strabismus plate. Outer wall of the through shaft hole 221 formed in the strabismus plate 22 in a fixed manner and symmetrical with the through shaft hole 211 of the strabismus plate 21. In the shaft 141 of the rotary knob 14 in the axis of the spinning shaft 31, fixed to the shaft 36, and then fastened with a screw 15, by rotating the handle 14, the plate 21 and (22) The wheel 31 and the primary gear 41 are coaxially interlocked with each other.

The secondary gear 42 and the tertiary gear 43 meshed with the primary gear 41 are gears coupled in two stages so that driving is transmitted to the fourth gear 44 meshed with the tertiary gear 43. Was inserted into the gear shaft 28 formed on the outer side of the strabismus 21 and fastened with a release preventing screw 29.

In addition, the fourth gear 44 and the fourth gear 45 of the same size as the fourth gear 44 meshed with the third gear 43 are meshed with the fourth gear while the rotation drive is transmitted, and the spinning wheel The equal groove of the insertion recess 32 of 31 and the 1st rotation of the 4th and 5th gears 44 and 45 are comprised so that it may synchronize.

The cranks 46 and 47 have the same shape, and key grooves 462 and 472 are provided in the gear shafts 461 and 471 in the gear installation direction, and the eccentric shafts 463 and 473 in the middle. It is formed long and the rotating shaft 464, 474 is formed at the end of the gear shaft (461, 471) the inner wall in the rotary holes (212), 213 formed in the lower front of the strabismus 21 (21) In the outer wall in the direction of the crank gear shaft 461 is inserted into the key 441 and the key groove 462 protruding into the shaft hole of the fourth gear 44, the insertion and coupling, and the fifth gear on the crank gear shaft 471 Crank rotation shaft in the rotational hole 222, 223 of the swash plate 22 symmetrically formed with the rotation hole 212, 213 of the strabismus plate 21, inserting and coupling 45 in the same manner as above. Through 464 and 474, the eccentric shaft 463 and the eccentric shaft 473 are configured to be opposite to each other (the other one is downward when one is upward).

The trolley 51 installed on the two eccentric shafts 463 and 473 has a cutting knife 53 on the front surface thereof, and a half moon type 513 so as to horizontally install the eccentric shaft 473 on both side surfaces. Grooves are formed, and the eccentric shaft 463 is installed at the rear, and the long holes 511 and 512 are symmetrical on both sides so that the wheelbase of the eccentric shafts 463 and 473 can be narrowed during the driving rotation. It is formed. T-shape bearing (54) that fits into the groove of the middle portion is formed in the upper half-wall type 541, in combination with the half-wall type 513 of the groove to form the axial hole of the eccentric shaft (473) and the eccentric shaft in the shaft hole As the 473 is free to rotate, the eccentric shaft 473 is grounded to the middle half-wall type 513 of the trolley 51, and the T-shaft bearing 54 is fitted to fix the long hole formed at the rear of the trolley 51. The eccentric shaft 463 is penetrated by the eccentric shaft 463 at 511 and 512 so that when the eccentric shaft 463 is raised, the eccentric shaft 473 is moved downward, thereby causing the two eccentric shafts 463 and 473 to move downward. The trolley | bogie 51 provided in ()) is comprised so that it may perform a shio soo movement and a parabolic movement simultaneously up and down.

In the drive of the present invention assembled as described above, when the rotary knob 14 is rotated, the wheel 42 and the primary gear 41 of the driving gear rotated and coaxially coupled thereto are rotated and engaged with the gear 42. The driving force is transmitted to the 43, 44, and 45, and the bogie 51 installed on the two cranks 46 and 47 fixedly coupled to the fourth and fourth gears 44 and 45 is also shown in FIG. 6 (a). As shown in Fig. 6 (f), the cutting knife 53 attached to the front surface of the trolley 51 forms the blade insertion groove 32 of the wheel 31 by precisely achieving a rotational motive with the wheel 31 in a parabolic and shio operation. The adhesive tape 61 wound around the outer periphery is cut | disconnected in the order of FIG. 6 (a)-6 (f).

As described above, the present invention rotates the two crankshafts in opposite directions, and the bogie installed there is precisely synchronized with the rotation of the spinning wheel so that the parabolic and shio movements are performed, and the cutting knife attached to the bogie has It cuts the adhesive tape wrapped around the spinning wheel to a certain length while entering and exiting the blade insertion recess, which has relatively low noise and operation load and reduces manufacturing cost.
