Description

Technical Field

[0001] The utility model relates to the technical field of abrasive belt connection, in particular to a high-strength abrasive belt connection device for a polishing machine. Background Art

[0002] A polishing machine is a mechanical device used for surface polishing and grinding. It is usually used for surface treatment of metal, wood, plastic and other materials to improve their finish, gloss and surface quality. The main purpose of using a sanding belt connection device in a polishing machine is to ensure that the sanding belt can be firmly and stably fixed to the polishing head or other driving device during operation, so as to effectively complete the polishing and grinding work, and to ensure that the sanding belt will not loosen or fall off under high-speed rotation or high load. This is crucial to the safety and operational stability of the polishing machine, and avoids accidental falling off or displacement of the sanding belt during operation.

[0003] Existing abrasive belt connections usually use special adhesives or tapes to bond the two ends of the abrasive belt together, which can provide better stability and strength. Some abrasive belt designs use rubber connections, usually by embedding rubber strips or using rubber adhesives at both ends or joints of the abrasive belt to enhance the connection strength and durability.

[0004] However, when using abrasive belts for polishing, the abrasive belts themselves need to be replaced regularly due to friction and wear. This may increase the difficulty and workload of replacing abrasive belts connected by adhesives, because the adhesive may decompose or fail under long-term high-speed friction, resulting in a decrease in the adhesion of the abrasive belts. Therefore, a high-strength abrasive belt connection device for polishing machines is proposed to solve the above problems. Utility Model Content
