A kind of double-sided adhesive tape for automatic cutting

Abstract

The invention discloses double-sided adhesive convenient to automatically cut. A partition paperboard is arranged on the inner ring of the double-sided adhesive tape, an upper clamping head and a lower clamping head are arranged on the inner ring of the partition paperboard, a first sliding piece is fixedly connected with the right end of the lower clamping head, first sliding grooves are formed in the left and right ends of the first sliding piece, and a second sliding piece is slidably connected with the first sliding piece through the first sliding grooves; a squeezing spring is fixedly connected with the top end of the first sliding piece, a second sliding groove is formed in the second sliding piece, a stretching spring is arranged in the second sliding groove, a cutting-off shell isarranged above the upper clamping head, a track is arranged in the cutting-off shell, a cutter blade and a guiding rod are arranged in the track, the bottom end of the guiding rod is fixedly connectedwith the cutter blade, and the top of the guiding rod is fixedly connected with a pushing plate. The double-sided adhesive has the advantage that the user conveniently cuts the various double-sided adhesive automatically.

Description

technical field [0001] The invention relates to the field of double-sided adhesive tape, more specifically, relates to a double-sided adhesive tape which is convenient for automatic cutting. Background technique [0002] Double-sided adhesive tape is a roll-shaped adhesive tape made of paper, cloth, and plastic film as the base material, and then evenly coated with elastomer-type pressure-sensitive adhesive or resin-type pressure-sensitive adhesive on the above-mentioned base material. Those who stick some documents and other objects are composed of three parts: substrate, adhesive, release paper (film) or silicone oil paper. [0003] At present, during the use of double-sided tape, users use traditional methods to perform related operations on the double-sided tape, but the elastic plastic film in the double-sided tape is not easy to be torn by manpower. In the process of double-sided glue, the plastic film at the torn part and the glue below are often entangled together, ...

Problems solved by technology

[0003] At present, during the use of double-sided tape, users use traditional methods to perform related operations on the double-sided tape, but the elastic plastic film in the double-sided tape is not easy to be torn by manpower. In the process of double-sided glue, the plastic film at the torn part and the glue below are often entangled together, which brings great inconvenience to the user's work of tearing the plastic film, such as the description in the application number CN201811099719 , although the production efficiency and good rate of the ring-shaped double-sided tape have been improved, it has not brought convenience to the use of the double-sided tape for the user, so the above-mentioned problems still exist
