Description

Technical Field

[0001] The utility model relates to the technical field of coating mechanisms, in particular to a pressure-sensitive adhesive coating mechanism. Background Art

[0002] A major feature of pressure-sensitive adhesive is its pressure sensitivity, which means it can bond under slight pressure. This feature makes pressure-sensitive adhesive widely used in various applications, such as tapes, labels, stickers, medical dressings, etc. Another advantage of pressure-sensitive adhesive is that it does not require additional solvents or activators, so it is very convenient to use and more environmentally friendly.

[0003] When the existing pressure-sensitive adhesive coating mechanism is in use, the base fabric is laid on a workbench, the stirred pressure-sensitive adhesive is poured onto the base fabric along the distribution direction of the glue coating roller, and then the glue coating roller is controlled to roll along the base fabric so that the glue coating roller evenly coats the glue liquid on the base fabric. The step of pouring out the glue liquid is manually controlled, and the amount poured at each position is difficult to control, which makes it difficult to quickly and evenly complete the coating operation of the pressure-sensitive adhesive.

[0004] To this end, we propose a pressure-sensitive adhesive coating mechanism. Utility Model Content

[0014] Beneficial Effects

[0015] The utility model provides a pressure-sensitive adhesive coating mechanism, which has the following beneficial effects:

After the glue liquid is discharged, the sliding bracket is controlled to move forward and backward along the sliding track, so that the sliding bracket drives the pressure coating roller to evenly apply the linear glue liquid, thereby achieving the effect of evenly discharging the pressure-sensitive adhesive.

[0017] (2) When it is necessary to control the rolling pressure of the pressure-sensitive adhesive coating mechanism, the gravity of the movable arm hanging downward is controlled by adding or subtracting the gravity block to the support block.
