tape cutter

Abstract

The invention discloses a tape cutter, which is used for fixing and cutting tape rolls. The tape cutter includes a shell, a tape roll sleeve arranged in the shell and used for covering the tape roll, and a tape roll sleeve set on the tape roll. The sound-absorbing roller and the rolling wheel on one side of the roll sleeve, the housing is provided with an outlet near the rolling wheel, wherein a driving wheel is installed between the sound-absorbing roller and the rolling wheel, and the adhesive tape of the tape roll The head is wound out from the sound-absorbing roller, then wound around the driving wheel, then wound to the rolling wheel, and pulled out from the outlet. The tape roll sleeve is connected to the driving wheel through a transmission belt. The tape cutter of the present invention uses a transmission belt to drive the tape roll to rotate, so that the tape roll actively peels off the tape, that is, it can keep the tape peeling angle between the tape and the tape roll as an obtuse angle, thereby eradicating the peeling popping sound, so that when the tape cutter is used Has a mute effect.

Description

technical field [0001] The invention relates to a tape cutter, in particular to a silent tape cutter. Background technique [0002] Adhesive tape cutter is a small box sealing tool that is often used. Its style is similar. The main structure is an inner cylinder and a shell covering the inner cylinder. A serrated cutter is set on the top to cut off. This kind of structure cutter is relatively simple and common, but it is easy to produce tearing noise when the tape is cut. This plosive is further amplified to create a harsh noise. [0003] Please refer to figure 1 , when the ordinary cutter cuts the tape, the noise generated by the natural peeling of the tape is related to the following four factors: [0004] 1. Tape peeling angle A: [0005] Pull out the tape and pull it out, the tape is peeled off from the tape roll, the adhesive surface of the tape and the circumferential cut surface of the tape roll will form a peeling angle A at the peeling point, depending on the ad...

AI Technical Summary

Problems solved by technology

Although this design reduces the noise to a certain extent through the sound-absorbing roller, and refines the tearing and blasting sound into a sharp squeaking sound, this method cannot solve the noise problem based on the fundamental influencing factors

The reasons for its incomplete improvement can be summarized as follows: 1. The peeling of the tape by the tape roll 300 is still passively pulled by the tape. ; 2. The suspension tension section B of the tape is longer than the ordinary tape cutter, and the noise amplification effect is more obvious; 3. Adding the silencer roller can reduce the peeling jump distance C, and change the noise from rough to sharp. The noise is reduced to a certain extent, but it is far from silent; 4. The tape tension F is the same as that of ordinary cutters, and the tape is still tight, which does not improve the noise
