This utility model relates to the field of dispensing machine technology, and more particularly to an automatic three-axis dispensing machine. The automatic three-axis dispensing machine includes a worktable, a mounting frame connected above the worktable, a moving component mounted on the mounting frame, and an adjusting component connected to the moving component. Operating via a dust pump box, it can perform dust extraction through a first and second dust suction pipe. A connecting plate can fix the first and second dust suction heads to the sides of a first and second dispensing assembly. When the first and second dispensing assemblies move, the dust suction heads follow synchronously, ensuring that the dust suction range always covers the dispensing area. This cleans the worktable and dispensing area, preventing dust and impurities from contaminating the dispensing process, ensuring the adhesiveness and dispensing effect of the glue. Simultaneous dispensing by the first and second dispensing assemblies can accelerate the dispensing efficiency.

The present application relates to the technical field of medical polymer materials, in particular to a medical adhesive tape based on low-sensitization acrylate medical adhesive and a preparation method thereof, the medical adhesive tape is composed of 65-78% low-sensitization acrylate adhesive main body, 15-22% medical-grade breathable non-woven fabric substrate, 5-8% medical silicone release layer, 1.5-3% low-sensitization soothing auxiliary agent, 2-4% hydrogenated rosin tackifying resin, 0.3-0.8% multifunctional crosslinking agent and 0.1-0.5% low-temperature initiator by weight percentage; the adhesive main body is a ternary copolymer system, and the copolymer glass transition temperature is accurately controlled to be 243-253 K. The medical adhesive tape is prepared by low-temperature solution polymerization, low-sensitization modification, high-pressure micro-perforation coating and three-stage curing and sterilization process, has a peel strength of 1.0-2.5 N / 25 mm, a holding time of ≥24 h and a skin sensitization reaction grade of ≤ grade I, and has low sensitization, stable adhesion and high breathability, and can meet the use requirements of various medical fixation scenes in clinical applications.
