[0023] Below in conjunction with accompanying drawing, the present invention will be further described:
[0024] Such as figure 1 As shown, it is a schematic diagram of the first working process, with figure 1 Illustrate a kind of seamless hot-melt adhesive film production technique of the present invention as an example, it comprises the following steps:
[0025] The first step is to prepare TPU hot-melt collagen material particles, put the TPU hot-melt collagen material particles into the hopper connected to the extruder; pass the adhesive paper 2 with release function around the rubber roller 4 and emboss in turn Wheel 5, forming wheel 6, traction wheel 7 and take-up wheel 8;
[0026] The second step is to turn on the power supply and open the extruder; set the set temperature value when the extruder is produced; The TPU hot-melt collagen material is heated so that the TPU hot-melt collagen material reaches the extrusion temperature requirement after being processed. Pr...

Abstract
The invention relates to the technical field of a production technology of a hot-melt adhesive and particularly relates to a production technology of a non-sewn hot-melt adhesive film. The production technology mainly comprises the following steps: enabling TPU (thermoplastic polyurethane) hot-melt adhesive raw material particles to enter into an extruding machine from a hopper and be processed into an adhesive material, sending the adhesive material into a die head of an extruding machine via a screw rod, enabling the adhesive material to be attached on attaching paper on an embossed wheel after being extruded by the die head, and enabling a rubber roller to move forward and tightly press the embossed wheel; and enabling the adhesive material and the attaching paper to pass through the embossed wheel, then forming a hot-melt adhesive film sheet, pulling out the hot-melt adhesive film sheet via a forming wheel, enabling the hot-melt adhesive film sheet to pass through a traction wheel, then winding via a winding wheel, and finally producing the coiled non-sewn hot-melt adhesive film. As for the production technology of the non-sewn hot-melt adhesive film, bonding can be avoided during winding, a cooling facility does not need to be increased, the cost is lower, and the performances and the quality of the adhesive material are higher; furthermore, a product is smooth and aesthetic.
Description
Technical field: [0001] The invention relates to the technical field of hot melt adhesive production technology, in particular to a production technology of a seamless hot melt adhesive film. Background technique: [0002] Hot-melt adhesive film is a kind of plastic adhesive, which can replace industrial liquid glue, solid glue and PU glue. It has the advantages of environmental protection, non-toxic and no side effects. As an ideal environmentally friendly adhesive material, hot melt adhesive film has low melting point, high elasticity, acid resistance, alkali resistance, washing resistance, dry cleaning resistance, strong tensile strength, strong adhesion, and low melting point. It has been widely used in embroidery labels. , armbands, trademark bonding, suitable for clothing, shoes and hats, bags, medical, military coats, sportswear, toys and other fields. Due to the superior performance of the hot melt adhesive film, and in line with the general bonding processing stand...
