Problems solved by technology

[0004] 1) When using method 1 for processing, it is necessary to pre-cut the long winding pipe in advance, and then rewind one by one. In actual operation, it is also necessary to insert and accurately install the end pipe for winding through the pipe drawing equipment. Positioning, the whole operation process is relatively cumbersome;
[0005] 2) Compared with method 1, when using method 2, although the operation of pre-slitting and winding tube is omitted, in the process of directly cutting small tape parent rolls, it is mainly carried out segment by segment Slitting one by one, the slitting process of a single small tape master roll takes too long and the processing efficiency is low

Embodiment Construction

[0040] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and To facilitate its practice, but not as a limitation of the invention.

[0041] See attached Figure 1-9 Shown, a kind of production method of PET heat-resistant adhesive tape, production method specifically comprises the following steps:

[0042] S1. Substrate molding: use plastic granules and corresponding additives as raw materials, and use film blowing to form plastic film substrates;

[0043] S2. Substrate gluing: prepare the required glue according to the viscosity and purpose of the adhesive tape, and evenly coat the prepared glue on the plastic film substrate formed by blown film in step S1, and wind it up. Thereby preparin...

Abstract

The invention relates to a production method of a PET high-temperature-resistant adhesive tape, and concretely relates to an adhesive tape mother roll slitting and forming die device. The device comprises a rack, a conveyor, a rotary transposition mechanism, a pressing and shifting mechanism and a slitting disc group mechanism. The pressing and shifting mechanism and the rotary transposition mechanism are both arranged on the rack and distributed up and down, two conveyors distributed on the two sides of the rotary transposition mechanism are arranged on the rack, and the two conveyors convey materials from one side of the rotating transposition mechanism to the other side of the rotating transposition mechanism. According to the device provided by the invention, the whole small adhesive tape mother roll can be quickly and integrally slit in a wrapping, clamping and rotating die cutting manner, so that the trouble that in a traditional processing manner, a winding pipe needs to be slit in advance, and then the winding pipe is positioned and sleeved into a short pipe in a pipe drawing manner is solved; and the problems of long slitting time and low processing efficiency caused by adopting a one-by-one slitting mode in the traditional processing process are also solved.

Description

technical field [0001] The invention relates to the technical field of adhesive tape production and manufacturing, and specifically proposes a production method of PET high temperature resistant adhesive tape. Background technique [0002] PET high temperature resistant tape is an adhesive tape specially used in high temperature working environment, which is made of polyester resin as the main raw material. PET heat-resistant adhesive tape is mainly used in the electronics industry. It has excellent high-temperature resistance and electrical insulation properties. The temperature resistance is usually between 120 degrees and 260 degrees. It is often used in painting, baking varnish leather processing, coating masking and electronic parts manufacturing processes. Medium fixing, printed circuit board and high temperature processing shielding. [0003] The essence of PET high temperature resistant adhesive tape is adhesive tape. Except for the difference in material compositio...
