Problems solved by technology

However, at present, the trimming of tires is done manually with a hand-held cutter, which requires workers to accurately grasp the distance between the cutter and the tire, which is labor-intensive, and because each worker grasps the distance differently, the appearance of the tires trimmed by different workers is inconsistent. It affects the production quality of the tires, and the existing cutting knives have no protective measures, so that the lanugo or rubber edges that are cut off during shaving are easy to bounce to the face, causing personal injury to workers

Abstract

The invention belongs to the technical field of cutting knives, and provides a cutting knife for beard trimming of tires, which is arranged in pairs on two tire blocking plates arranged at intervals. The lower end of the rod is hinged with the tire blocking plate, the turning part is rotated on the side of the tire blocking plate, one end of which is hinged with the upper end of the telescopic rod, and the cutter head assembly is connected with the other end of the flipping part; When the cutter is trimmed, the roller rolls and fits on the tire to be trimmed to limit the distance between the cutter and the tire. The tool provided by the present invention can automatically turn over under the action of the telescopic rod and limit the distance between it and the tire through the roller, so that the spatial position of the tool will not change when the tire rotates, thereby avoiding damage to the tire, and the roller can adjust the tire Carrying out gears can reduce its shaking, thereby ensuring the effect of tire trimming, making the appearance of the tires consistent after trimming, and effectively ensuring the production quality of the tires.

Description

technical field [0001] The invention relates to tire production auxiliary equipment, in particular to a cutting knife used for tire trimming, which belongs to the technical field of cutting tools. Background technique [0002] With the rapid development of the tire industry, customers have higher and higher requirements for tire quality, and small defects on the appearance of tires will make customers worry about the quality of tires. After the tire is produced, the appearance of the tire needs to be trimmed. The trimming of the tire includes not only tire lanugo, but also the rubber edge of the tire. [0003] In order to prevent the appearance of tires from being damaged due to wrong actions by workers during tire trimming, and considering the low efficiency of tire trimming, a smart and lightweight tool is needed to quickly remove tire defects without damaging the tires. [0004] In the prior art, tools are often placed on the tire surface, and the tire is rotated to remo...
