An adjustment part (50) pivots onto the drawback roll wheel (38), so when the gear is driven to joggle with the drawback gear (37) to run, a frictional resistance is caused between the drawback roll wheel (38) and the drawback gear (37) to keep the tightness of drawback of the drawback release paper (421), preventing the release paper (421) from being blocked on the drawback roll wheel (38) and then the double-sided tape from not drawing back completely.
Description
- This invention relates to a double-sided tape dispenser that adjusts the degree of drawback tightness of a release paper.
- With reference to
figure 1 as an assembly view of a conventional double-sided tape dispenser comprising abody 10 formed with a first shell 11and asecond shell 12, in which several protrudingwedge flakes 111 are provided at a side of the circumference offirst shell 11 andwedge slots 121 are formed at the outside of the circumference ofsecond shell 12, which are opposite to thewedge flakes 111, in order to make thefirst shell 11 wedge to thesecond shell 12. Ahand grasp portion 122 is formed at a lower side of thesecond shell 12, stretching axially outwardly. Atape release port 112 is formed where the front ends of thefirst shell 11 andsecond shell 12 are opposite to each other. Atape release seat 12 is formed outwardly and transversally at thesecond shell 12, which is opposite to thetape release port 112 On thetape release seat 123, aroller 124 and acarrier wheel 125 are provided sequentially and pivot axially to each other.Several ribs 125a are provided at intervals of distance around the circumference ofcarrier wheel 125. Theroller 124 is arranged outside thebody 10. Arolling tape mechanism 13 is provided inside thesecond shell 12. In therolling tape mechanism 13, a firststationary shaft 126 and a secondstationary shaft 127 that project are arranged axially close together at the inner side ofsecond shell 12, in which adriving gear 14 pivots onto the firststationary shaft 126 and adrawback gear 15 linking with thedriving gear 14 pivots onto the secondstationary shaft 127. Thedrawback gear 15 joggles with thedriving gear 14 to run in a reverse direction. Aroll wheel 141 that projects is provided in the center of drivinggear 14 along the firststationary shaft 126. A double-sided tape 16 is provided to scroll over theroll wheel 141 and comprises ascroll release paper 161. Double-sided adhesive is formed outside the circumference ofrelease paper 161. The outer circumference of the tail ofrelease paper 161 moves around the top end ofcarrier wheel 125 and then moves around from the inner circumference toward the lower-end side ofroller 124. Finally, the tail ofrelease paper 161 that is formed with no double-sided adhesive is made to scroll over and clip on thedrawback roll wheel 151 that projects in the center ofdrawback gear 15. - There is no adjustment part that may properly tighten the conventional
drawback release paper 161 that has scrolled on thedrawback roll wheel 151. After drawback, when the amount and weight ofrelease paper 161 on thedrawback roll wheel 151 increases, the frictional resistance to thedrawback gear 15 increases, making thedrawback release paper 161 over thedrawback roll wheel 151 and not run smoothly and not completely draw back and even skid on the surface ofroller 124 to which a force is applied, thereby the follow-up functions being impacted. Thus, thefirst shell 11 must be separated from thesecond shell 12, thedrawback release paper 161 must be removed, and the frictional resistance between thedrawback gear 15 and thedrawback roll wheel 151 must be reduced for smooth running. - Consequently, because of the technical defects of described above, the applicant keeps on carving unflaggingly through wholehearted experience and research to develop the present invention, which can effectively improve the defects described above.
- It is a main object of this invention to provide a double-sided tape dispenser in which a drawback roll wheel is provided with an adjustment part for tightness adjustment. By adjusting the tightness of drawback of the release paper, the drawback release paper may be made to run smoothly, preventing the release paper from being blocked or not drawing back completely.
- The double-sided tape dispenser according to this invention comprises a body. A tape release port is formed at the front ends of the body that are opposite to each other. A rolling tape mechanism is provided in the body an exit of which is formed with a tape release seat that is formed outwardly and transversally. On the tape release seat, a roller that keeps adhesive close to a determined surface, and a
carrier wheel 125 are provided sequentially. A driving gear and a drawback gear that are provided to drive the tape pan pivot axially to the inner wall of body. A release paper provided with double-sided adhesive winds around the tape pan. The outer circumference of release paper moves around the carrier wheel and then the roller from the inner circumference, and the tail of release paper that is formed with no double-sided adhesive is made to scroll over and clip on the drawback roll wheel. This invention is mainly characterized that an adjustment part is provided on a central axis of the drawback gear, mainly comprising a shift limit bush. A projecting shift limit portion is provided in the shift limit bush at two relatively axial sides. A compression spring is axially set around the shift limit bush. Relatively, an adjustment ring is set around a top end of the compression spring to make the compression spring compress the drawback roll wheel and the drawback gear for a radial frictional resistance, and thus the release paper is made to drive and draw back toward the drawback roll wheel through the roller; at the same time, the drawback roll wheel and the drawback gear run reversely. A concave portion is axially formed at the inner wall of adjustment ring that is opposite to the shift limit portion. Several adjustment portions the sets of depth of which are different are axially formed around among the concave portions. The top ends of adjustment portions communicate with each other. With the adjustment ring axially running, the compression spring is compressed toward a determined adjustment portion to cause a frictional resistance between the drawback roll wheel and the drawback gear, making the drawback roll wheel and the drawback gear smoothly run reversely. When the amount and weight of drawback release papers on the drawback scroll increases, the degree of tightness of the adjustment ring that pushes down the compression spring may increase to wedge the adjustment portion, keeping proper frictional resistance between the drawback roll wheel and the drawback gear to easily adjust the release paper for the degree of tightness at the time of drawback. -
