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-melt coating device, which includes a frame and a plurality of rollers, and the plurality of rollers are connected by a conveying device, and the rollers include an unwinding roller, a regulating roller, and a paper guide roller sequentially connected to the frame , composite roll A, composite roll B, cooling roll, tension control roll A, cooling roll group, and tension control roll B, C, D and winding roll A or B, described composite roll is connected with die head, tension control There is an air knife on the roller; the invention also provides a paperless hot-melt coating process. Compared with the traditional hot-melt coating process, the present invention solves the problems of high cost of release paper, many release transfer processes, high energy consumption, and large area occupied by equipment, and has the advantages of fast process speed, high yield rate, and equipment footprint Advantages of small 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...
