[0002] PUR adhesive dot transfer laminating machines are commonly used composite material production equipment. They typically utilize PUR hot melt adhesive for efficient bonding and lamination processes. By melting solid PUR hot melt adhesive, the machine precisely controls the application or transfer of liquid adhesive to specific locations.

[0003] Application No. 202120229531.3 mentions a PUR adhesive dot transfer dual-purpose laminating machine, including a base, side plates, a worm gear reducer, a blade, an adhesive dot roller, a silicone pressure roller, a spreading roller, a cylinder, a support rod, a swing arm, gears, a screw, a main motor, an auxiliary motor, a first guide roller, and a second guide roller. The side plates are installed on both sides of the base to form a whole. The adhesive dot roller is installed between the side plates, and the guide roller is installed between the blade and the silicone pressure roller, and between the side plates, located at the upper right corner.

[0004] The process utilizes guide rollers to guide the fabric and ensure smooth transport. However, when transferring PUR adhesive dots to fabrics with different tensions, some fabrics may become loose due to tension mismatch during transport, affecting the processing effect. Consequently, the PUR adhesive dot transfer laminating machine is not convenient for adapting and adjusting to fabrics with different tensions, and thus has certain limitations.
