Description

Technical Field

[0001] The utility model belongs to the technical field of base paper gluing, in particular to a gluing mechanism for producing thermal transfer paper. Background Art

[0002] Thermal transfer paper uses special thermal transfer ink to print various patterns on a special kind of paper, and then transfers the pattern to the product through temperature and pressure. This special paper in the thermal transfer process is called inkjet thermal transfer paper. The surface of the inkjet thermal transfer base paper needs to be coated with sizing agent during production, and the sizing mechanism is generally used for coating and sizing.

[0003] A Chinese patent with publication number CN219400817U discloses a double-sided gluing mechanism, comprising: a base; the base adopts a rectangular plate structure, and trapezoidal slide structures are provided on the front and rear sides of the top of the base; a fixed frame is fixedly arranged in the middle of the top of the base; the fixed frame adopts a rectangular frame structure, and guide rail structures are provided on both sides of the inner wall of the fixed frame; two groups of connecting plates are slidably arranged on the inner side of the fixed frame; the fixed frame also includes: a glue storage barrel, which is arranged on the top of the fixed frame; a second motor, which is fixedly arranged on the top of the fixed frame; a bidirectional lead screw, which is rotatably arranged on the inner side of the fixed frame, and the bidirectional lead screw is transmission-connected to the second motor.

[0004] The gluing mechanism in the above-mentioned prior art still has certain shortcomings during actual use. For example, during the gluing process, the surface of the paper is loose when gluing, which will affect the gluing quality of the paper. Secondly, after gluing, the motor drives the winding roller to wind up the paper winding sleeve. When removing it, the staff needs to squat and then operate the screw to make the slide plate on one side of the winding roller move away from the fixed plate before the rolled paper roll can be removed, which is very inconvenient.
