1. Anti-Blocking Adhesive Mixing Equipment for Adhesive Production (Patent Publication No.: CN216799534U )

Technical Field: Adhesive manufacturing equipment

The earliest patented device addresses the critical issue of material blockage in adhesive mixing. It features a specially designed mixing chamber with spiral agitators and self-cleaning blades, preventing viscous adhesive materials from accumulating in corners. The anti-blocking structure ensures uniform mixing efficiency while reducing maintenance downtime, which is vital for mass production of pressure-sensitive adhesives used in label manufacturing. By minimizing blockages, the equipment enhances raw material utilization and reduces production costs in the adhesive packaging sector.

2. Dust Removal Device for Release Paper Production (Patent Publication No.: CN222306719U )

Technical Field: Release paper manufacturing

This utility model innovates in dust control during release paper production. The device comprises a dust removal chamber with a detachable dust drawer, inside which adhesive dust rolls are mounted on a fixed frame. Roller shafts beneath the frame enable smooth sliding, while anti-static ion bars eliminate electrostatic dust adsorption. The lock core mechanism allows quick extraction of the drawer for maintenance, reducing repair time by 50% compared to traditional designs. This solution is crucial for maintaining the cleanliness of release paper, ensuring high-quality adhesive label lamination without dust-induced defects.

3. Die-Cutting Device for Release Paper Production(Patent Publication No.: CN222309039U )

Technical Field: Release paper processing

Targeting the die-cutting stage, this device integrates a cleaning unit and air-blowing system. The die-cutting housing features a lifting mechanism for precise blade adjustment, while the cleaning unit uses a reciprocating brush to remove residual paper scraps from the blade edge. The air-blowing unit adjusts its angle as the cleaning plate moves, ensuring comprehensive debris removal. This design prevents blade clogging and maintains consistent cutting accuracy, which is essential for producing complex-shaped adhesive labels with minimal waste.

4. Precision Laminating and Slitting Device for Release Paper Rewinding (Patent Publication No.:  CN222138181U )

Technical Field: Release paper slitting and rewinding

As the latest patent, this device optimizes release paper post-processing. It features a main frame with a detachable rewinding rod and conveying roller, allowing quick replacement of different specifications of rewinding wheels and spacing sleeves. The slitting blade is equipped with an anti-adhesion cone plate, which separates slit release paper layers to prevent sticking. This modular design reduces equipment replacement costs by 30% and ensures precise slitting for various label widths, meeting the diverse needs of the packaging industry.

5. Aging and Peeling Detection Device for Release Paper (Patent Publication No.: CN217033567U)

Technical Field: Release paper quality inspection

This device addresses the critical need for aging resistance testing in release paper. It includes a cabinet with lifting rails and an electric hydraulic cylinder, supporting two aging detectors that inspect the paper surface from both sides to eliminate blind spots. During peeling tests, clamping plates secure the release paper, while a peeling wheel on the lifting plate adapts to different paper specifications. The design ensures accurate detection of aging-induced adhesion changes, guaranteeing that release papers maintain their peel force standards for long-term storage in label applications.

6. Easy-Adjustable Gluing Device for Adhesive Production (Patent Publication No.: CN216880095U)

Technical Field: Adhesive coating equipment

In the adhesive coating process, this device solves the challenge of adjusting glue application thickness. It features an adjustable structure with a gluing box, glue storage tank, and a servo motor-driven telescopic column. The spacing between the gluing roller and adjusting column can be fine-tuned via a spring-loaded mechanism, adapting to different adhesive film thickness requirements. This flexibility is crucial for producing high-precision adhesive layers in label stock, ensuring consistent adhesion strength across various packaging applications.

7. A multi-stage mixing device for self-adhesive production (Patent Publication No.: CN216856345U )

Technical Field:  self-adhesive mixing device

The device is innovatively equipped with a sweeping and blowing unit. Sweeping plate with a special structure to efficiently reciprocate sweeping knife edge waste; blowing unit with the position of the sweeping plate to adjust the spray angle, a full range of blowing, significantly improve the die-cutting accuracy and product quality, in line with the packaging self-adhesive labeling industry's stringent needs.

8. An efficient cutting device for self-adhesive production with easily adjustable cutting position (Patent Publication No.: CN216807550U )

Technical Field:  self-adhesive cutting device

The servo motor drives the belt wheel to drive the screw rotation, the slider moves along the screw and anti-rotation through the slide groove, driving the fixed frame to accurately adjust the cutting position, which is both easy to adjust and improve the movement accuracy, and enhance the practicality of the device.
