Novel rubber strip for boneless doctor blade

Abstract

The novel boneless doctor blade adhesive tape comprises a clamping section, a neck swinging section and a cutting edge which are integrally formed, the clamping section comprises a first transverse piece, a second transverse piece and a third transverse piece which are sequentially arranged from top to bottom, and the middle of the first transverse piece, the middle of the second transverse piece and the middle of the third transverse piece are connected through a vertical connecting piece; the upper end of the swing neck section is connected with the middle of the third transverse piece, the lower end of the swing neck section is connected with the cutting edge, and the first transverse piece and the second transverse piece are horizontally arranged. The thickness of the third transverse sheet is 0.8 mm; the height of the swing neck section ranges from 1.55 mm to 1.6 mm. The cutting edge comprises an upper section, a connecting section and a cutting edge point which are sequentially connected from top to bottom, and the cutting edge is integrally in a Y shape. According to the invention, the rigidity of the cutting edge and the overturning flexibility of the swing neck section are improved, the conversion of the contact angle is completed through the deformation of the swing neck section, the cutting edge is prevented from curling, the contact angle is close to an ideal 45-degree range, and the contact between the edge of the cutting edge and glass is ensured, so that the bad conditions such as a water film, shaking, abnormal sound and the like can be eliminated.

Description

technical field [0001] The invention relates to the field of rubber strips, in particular to a novel rubber strip for boneless scrapers. Background technique [0002] When the wiper rubber strip is working, the edge of the rubber strip is in contact with the glass surface. The function of the edge of the rubber strip is to wipe off the rainwater and water stains attached to the glass surface. During the working process, due to the contact of the scraper arm and the angle of attack, an angle will be formed between the edge of the rubber strip and the glass surface. We call this angle the contact angle. Ideally, we want this contact angle to be 45°. But in the actual use process, due to the movement of the scraper and the change of the glass surface, the contact angle is constantly changing. We hope that the change of the contact angle is within the range of 45°±15°. [0003] Traditional wiper rubber strips rely on the deformation of the rubber strip edge to change the conta...
