Description

Technical Field

[0001] The utility model relates to the technical field of coating spraying, and more specifically, to a friction-reducing coating spraying device. Background Art

[0002] The piston rubber ring of the piston syringe can create a closed space for the injection, making the air pressure in the tube lower than the atmospheric pressure. The liquid medicine is pressed into the needle tube under the action of atmospheric pressure. When producing the piston rubber ring of the piston syringe, it is necessary to spray PTFE coating; the Chinese name of PTFE is polytetrafluoroethylene, which is called "non-stick coating" or "easy-to-clean material; and spraying PTFE coating on the piston rubber ring of the piston syringe can reduce the friction coefficient of the piston rubber ring of the piston syringe and have a higher non-stick effect. For this reason, a friction-reducing coating spraying equipment is proposed to spray PTFE coating on the surface of the piston rubber ring of the piston syringe.

[0003] The existing anti-friction coating spraying equipment can only spray on a single syringe piston rubber ring, which affects the work efficiency to a certain extent. In addition, the coating does not solidify after spraying, causing the coating liquid to flow and requiring manual secondary air drying. Utility Model Content
