Embodiment 1

[0023] A process for coating using the above-mentioned paperless hot-melt coating device, comprising the following steps:

[0024] 1. Pour non-agglomerated hot melt rubber particles into the die head, adjust the speed of the die head to 2m / min, and squeeze out the residual glue;

[0025] 2. Adjust the pressure of the unwinding roller to 18MPa, and pass the substrate sequentially through the unwinding roller, regulating roller, paper guide roller, composite roller A, composite roller B, cooling roller, tension control roller A, cooling roller group, and Tension control rolls B, C, D, and finally drawn to take-up roll A or B;

[0026] 3. Set the base material tension of the unwinding roller to 25Mpa, and it is advisable that the knitted fabric does not stretch or wrinkle;

[0027] 4. After observing that the film on the die head of the extruder is transparent and smooth, cut off the film on the die head of the extruder, remove the rubber baffle on the extruder, and move the die...

Abstract

The invention provides a paperless hot melting coating device which comprises a rack and a plurality of rolls, wherein the rolls are connected with one another by a conveying device; the rolls include an unwinding roll, an adjusting roller, a paper guide roll, a laminating roll A, a laminating roll B, a cooling roll, a tension control roll A, a cooling roll group, a tension control roll B, a tension control roll C, a tension control roll D and a winding roll A or a winding roll B which are sequentially connected with the rack; the laminating rolls are connected with a die head; and an air knife is arranged on the tension control rolls. The invention further provides a paperless hot melting coating technology. Compared with the traditional hot melting coating technology, the paperless hot melting coating technology solves the problems of high release paper cost, more release transfer procedures, high energy consumption and large equipment floor area, and has the advantages of high technology speed, high finished product rate, small equipment floor area and low cost.

Description

technical field [0001] The invention relates to the field of hot melt adhesives, in particular to a paperless hot melt coating device and process. Background technique [0002] As we all know, hot melt adhesives do not produce harmful pollutants to the environment, and hot melt adhesives are solid at room temperature, which is convenient for storage, packaging and transportation. Therefore, the application of hot melt adhesives in today's society has penetrated into all walks of life. [0003] With the popularization of hot melt adhesive application, hot melt adhesive coating technology has developed accordingly. Compared with traditional solvent-based and water-soluble coating processes, hot-melt coating solves the drawbacks of traditional processes. At present, the hot-melt coating process has been widely used in: trademark labels, self-adhesive tapes, electronic tapes, medical dressings, medical tapes, clothing material composites and other industries. The traditional ho...
