Working Principle

The telescopic rods of the polishing lifting devices of the polishing mold assembly of the polishing device retract and drive the polishing molds to move downward. The sealing strip is fed into the rectangular polishing frame from above the polishing guide frame at the end of the rectangular polishing frame of the polishing and cleaning frame away from the polishing traction device, and sequentially passes through the gaps between the polishing grinding wheels of the two polishing heads of the polishing device and the polishing molds of the polishing mold assembly, and between the cleaning wheel of the cleaning head of the cleaning device and the polishing molds of the polishing mold assembly, and then extends out of the rectangular polishing frame from above the polishing guide frame at the end close to the polishing traction device.

Turn the polishing handwheel of the polishing adjustment assembly of the polishing traction mechanism of the polishing traction device. The polishing screw rod and polishing support plate drive Polishing Traction Assembly II to move upward. Meanwhile, the polishing traction swing arm is pulled to swing around the tail end of the L-shaped edge of the polishing traction support arm fitted with the polishing traction idle gear, and the polishing traction support arm is pulled to swing around the shaft of the No.1 driving polishing roller. Afterwards, the sealing strip extending out from above the polishing guide frame at the end of the rectangular polishing frame close to the polishing traction device is guided between the polishing traction belts of Polishing Traction Assembly I and Polishing Traction Assembly II.

Then reversely turn the polishing handwheel of the polishing adjustment assembly to clamp the sealing strip. The telescopic rods of the polishing lifting devices extend out, and the polishing molds lift the sealing strip until it contacts the polishing grinding wheels of the polishing heads of the polishing device and the cleaning wheel of the cleaning head of the cleaning device. Adjust the nuts at the tail ends of the transverse adjustment screw rods of the transverse adjustment assemblies of the polishing device and the cleaning device, as well as each polishing handwheel of the height adjustment assemblies and angle adjustment assemblies, so that the positional relationship between the sealing strip and the polishing grinding wheels and cleaning wheel is accurate, and the compression degree meets requirements.

Start each power unit of the polishing and cleaning device for the pressure-sensitive adhesive tape production line. Driven by the polishing traction device, the sealing strip travels toward the polishing traction device after sequentially passing through the gaps between the polishing grinding wheels of the polishing heads, the cleaning wheel of the cleaning head and the polishing molds from the end of the rectangular polishing frame of the polishing and cleaning frame away from the polishing traction device. During this process, the sealing strip is polished by the polishing grinding wheels, and its original smooth surface is roughened to facilitate subsequent gluing and reliable adhesion. Afterwards, the cleaning wheel made of soft materials removes residual debris on the surface of the sealing strip. Debris generated during polishing and cleaning falls into the debris collecting box through the polishing debris hopper arranged inside the hexahedral polishing box.

The polishing motors of the polishing heads and cleaning heads are high-speed motors and will generate a large amount of heat during operation. Therefore, the water pumps of the cooling system deliver low-temperature water to the polishing motors through water pipes. Heat is taken away when water flows back to the water tank, ensuring normal operation of the polishing motors. Fine debris generated during polishing and cleaning is sucked away by the dust removal system connected to the air guide holes of the polishing protective covers of the polishing heads and cleaning heads via air ducts, and discharged into the atmosphere after dust removal and purification.

Beneficial Effects

Compared with the prior art in this field, the present invention is provided with the polishing traction device to ensure stable operation of the sealing strip, facilitating polishing and cleaning and laying a foundation for subsequent gluing and laminating processes. The polishing traction device is equipped with the polishing adjustment assembly, which not only facilitates feeding of the sealing strip before traction, but also enables timely adjustment of the clamping force exerted by Polishing Traction Assembly I and Polishing Traction Assembly II on the sealing strip to ensure smooth and stable passage of the sealing strip.

The arrangement of the polishing device and cleaning device enables efficient and rapid roughening of the original smooth surface of the sealing strip and thorough removal of polishing debris, thereby greatly reducing labor demand and lowering workers’ labor intensity. The polishing mechanisms of the polishing device and cleaning device are provided with transverse adjustment assemblies, height adjustment assemblies and angle adjustment assemblies, so that the transverse position, height and angle of the polishing grinding wheels and cleaning wheel can be adjusted to adapt to polishing and cleaning of sealing strips with different cross-sectional shapes and sizes.

The cooling system ensures normal operation of the high-speed motors of the polishing device and cleaning device. The dust removal system timely absorbs fine debris generated during polishing and cleaning, preventing environmental pollution and protecting the physical health of operators.
