Chinese patent CN212732769U discloses a foam double-sided tape coating equipment, which is equipped with an applicator roller, a spreader roller, and a coating roller. The applicator roller adheres the adhesive from the material trough, and the spreader roller evenly transfers the adhesive to the surface of the coating roller. The coating roller then evenly rolls the adhesive onto the surface of the substrate, thereby achieving uniform coating of the substrate. However, it requires the design of two sets of parallel applicator rollers, spreader rollers, and coating rollers. The coated substrate needs to be wound up below the two sets of rollers, and the unloading roller is located above the coating mechanism, which is inconvenient for unloading and winding.

The second coating roller 8 rolls to apply glue to the other side of the substrate. Both sides of the substrate are coated with glue at the contact position of the first coating roller 7 and the second coating roller 8. This coating structure does not affect the feeding and winding, and the operation is simple.

[0025] Furthermore, a water trough is provided on one side of the bottom of the glue tank 11, and a guide plate 12 is fixed on the same side of the bottom of the glue tank 11, with the guide plate 12 being inclined.

The guide roller 14 is located behind the second paint roller 8, and the two rollers 15 are located behind the guide roller 14.

[0027] There is a certain distance between the second coating roller 8 and the guide roller 14. The double-sided adhesive is conveyed by the guide roller 14 to the two rollers 15 for uniform rolling, so that the adhesive is evenly coated on both sides.

[0028] Furthermore, a sixth mounting frame 16 is provided behind the second mounting frame 3, and a receiving roller 17 is provided on the sixth mounting frame 16. The receiving roller 17 is located at the very end of the frame 1.

[0029] Furthermore, there are three guide rollers 4, and the height of the last guide roller 4 is greater than the height of the first coating roller 7.

[0030] Furthermore, the second mounting frame 3 is provided with a lifting groove 18, and a movable seat 19 is provided in the lifting groove 18.

[0031] By rotating the screw 20, the movable seat 19 moves up and down within the lifting groove 18, thereby adjusting the distance between the second coating roller 8 and the first coating roller 7 to meet the coating requirements of substrates with different thicknesses.

[0032] Furthermore, the third mounting frame 5 is provided with an unwinding roller 21 for placing the release paper roll. The unwinding roller 21 is located in front of the unloading roller 6. The frame 1 is provided with multiple conveying rollers for guiding the release paper. The conveying rollers are located behind the unwinding roller 21.

[0035] The adhesive coating equipment also includes a drive mechanism, which consists of multiple motors used to drive the rotation of the rollers.

[0036] Working principle: The base material is placed on the unloading roller 6, and the release paper material is placed on the unwinding roller 21. The base material is conveyed by three guide rollers 4 to the space between the first coating roller 7 and the second coating roller 8. The lower part of the first coating roller 7 is immersed in the glue tank 9. The first coating roller 7 rolls in the glue tank 9 to apply glue to one side of the base material. The guide plate 12 guides the glue in the glue tank 11 to the second coating roller 8. The second coating roller 8 rolls to apply glue to the other side of the base material. The two sides of the base material are coated with glue at the contact position of the first coating roller 7 and the second coating roller 8. After being coated with glue, the base material is conveyed by the guide roller 14 to the space between two parallel rollers 15 for uniform rolling. Then, the double-sided adhesive is conveyed to the space between two composite pressure rollers 24. At the same time, the release paper is conveyed to the space between the two composite pressure rollers 24 by multiple conveying rollers. The composite pressure rollers 24 realize the pressing and lamination of the release paper and the double-sided adhesive. Finally, the double-sided adhesive is wound up on the take-up roller.

[0037] This invention immerses the lower part of the first coating roller 7 in the glue tank 9, and uses the guide plate 12 to guide the glue in the glue tank 11 to the second coating roller 8. The rolling of the first coating roller 7 and the second coating roller 8 achieves simultaneous application of glue to both sides of the substrate material. The operation is simple and the feeding and winding are convenient.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
