Waste pressure sensitive adhesive tape recycling device

Abstract

The invention discloses a waste pressure sensitive adhesive tape recycling device, which comprises a frame, wherein a primary adhesive removing mechanism, a secondary adhesive removing mechanism and atraction mechanism are arranged on the frame; the traction mechanism is mounted between the primary adhesive removing mechanism and the secondary adhesive removing mechanism; an unwinding rotary drumis arranged on one side of the frame; a winding rotary drum is arranged on the other side of the frame; a driving motor is arranged on the other side of the frame; a driving shaft is arranged at thefront part of the driving motor; the winding rotary drum is mounted on the outer peripheral surface of the driving shaft in a sleeved manner; and the primary adhesive removing mechanism, the secondaryadhesive removing mechanism and the traction mechanism are mounted between the unwinding rotary drum and the winding rotary drum. The device can be convenient to pull and control a sensitive adhesivetape in the conveying process, so that the conveying stability of the sensitive adhesive tape is better; and the device is convenient to remelt an adhesive layer on the waste pressure sensitive adhesive tape, so that the efficiency of melting the adhesive layer on the pressure sensitive adhesive tape is greatly improved.

Description

technical field [0001] The invention relates to a recycling device, in particular to a recycling device for waste pressure-sensitive adhesive tapes. Background technique [0002] There are two types of melting furnaces: gas type and electric melting furnace; the advantages of gas type: observe the melting state of the sample at any time, simple and easy to operate, and low price. Disadvantages: The temperature control is not as accurate as the electric melting furnace, and the laboratory gas modification is required. Advantages of electric melting furnace: high degree of automation, precise temperature control, large number of melting samples at one time. Disadvantages: The molten state of the sample cannot be observed. A special type of tape made by applying a special adhesive to a tape-like substrate. It consists of pressure-sensitive adhesive, base material, primer, back treatment agent, etc. Pressure sensitive adhesive is the most important component of pressure sens...

AI Technical Summary

Problems solved by technology

Disadvantages: temperature control is not as accurate as electric melting furnace, and laboratory gas modification is required

Disadvantage: unable to observe the molten state of the sample

The existing melting furnace is inconvenient to melt the pressure-sensitive adhesive tape, especially it is inconvenient to peel off the adhesive layer on the pressure-sensitive adhesive tape, and the efficiency of recycling the base film of the pressure-sensitive adhesive tape is low
