Description
Technical Field
[0001] This utility model belongs to the technical field of sealing strip production equipment, and specifically relates to an online grinding device for automotive sealing strips. Background Technology
[0002] Automotive weatherstripping is an important component of automobiles. It fills the gaps between body parts and has functions such as shock absorption, waterproofing, dustproofing, sound insulation, and decoration. High-quality automotive weatherstripping can improve the comfort of the driving experience and protect the vehicle body.
[0003] In the production of rubber sealing strips for automotive glass, a backing adhesive is required. This adhesive is essentially a double-sided adhesive tape applied to the rubber strip, allowing for easy bonding when installing the sealing strip onto the automotive glass by simply peeling off the protective layer of the adhesive tape. However, because the rubber sealing strips produced after vulcanization from the extruder have a smooth surface, there is a problem with insufficient adhesion strength to the double-sided adhesive. To solve this problem, existing technology uses a grinding device to grind the adhesive-backed area to ensure the bonding strength between the adhesive and the sealing strip.
[0004] The existing polishing device includes a bamboo-joint tube, a compressed air supply structure, a dust removal structure, a box arranged in the left-right direction, a positioning mold for supporting the sealing strip, N adjustment seats arranged side by side inside the box, and a polishing structure on the adjustment seats; the adjustment seats include a front-back adjustment handwheel, a vertical adjustment handwheel, and an angle adjustment handwheel, etc., and the polishing structure includes a motor arranged in the front-back direction and a polishing head on its rotating shaft, etc., the polishing head is located on the upper side of the sealing strip, and each polishing head is equipped with a positioning mold and at least one bamboo-joint tube.
[0005] In the prior art, in order to adapt to sealing strips of various specifications, the grinding structure needs to be adjusted, including front-to-back adjustment, vertical adjustment and angle adjustment. However, a lot of dust is generated during the actual grinding process. In the prior art, the adjustment seat and the grinding structure are both located in the box, and the dust is sucked away from the top of the box. Some of the dust will fall on the adjustment structure and accumulate, which will affect the accuracy of the adjustment seat or make it inconvenient to operate (such as requiring more force to rotate the handwheel).
