The invention discloses a three-layer pipe thermal shrinkage compound machine comprising a lifting assembly, an electric heating assembly and a clamping assembly. The lifting assembly comprises a supporting rod, a sliding block and sliding rail assembly, a transmission belt and a transmission motor, the clamping assembly comprises clamping cylinders and three-layer pipe positioning seats arranged side by side, and each clamping cylinder is arranged below the corresponding three-layer pipe positioning seat. The front end face of a movable sliding block is fixedly connected with the electric heating assembly, the electric heating assembly comprises a heating support, spring wires, temperature controllers, a plurality of heat insulation supports and electric heating sleeves, the electric heating assembly is adopted for the three-layer pipe thermal shrinkage compound machine, the peripheries of multiple three-layer pipes clamped side by side are lifted and heated from bottom to top, and the three-layer pipes are compounded into a whole through air cooling shrinkage. According to the thermal shrinkage technical index requirements of the three-layer pipes made of different materials, one-time thermal shrinkage is completed through high-temperature rapid lifting, one-time thermal shrinkage is completed through medium-temperature slow lifting, or multiple-time thermal shrinkage is completed through lifting circulation reciprocating, the forming speed is high, the thermal shrinkage efficiency is extremely high, and the three-layer pipe thermal shrinkage compound machine is simple and practical.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to a three-layer tube heat shrink compound machine. Background technique [0002] Modern medical devices must not only meet the needs of medical treatment, but also fully consider humanized design. Existing medical catheters used in clinical, endoscopic, and minimally invasive surgery are often bent, damaged, and broken. It is an extremely unsafe medical device for use in the inner cavity, and the broken part may harm the patient. of good health. Our company has designed a three-layer composite catheter, which uses a layer of metal wire to be spirally wound between the inner tube and the outer tube. After the outer tube is heated and shrunk, the metal wire layer and the inner tube are tightly bonded together to form a three-layer composite. The medical catheter has good bending resistance after compounding, which solves the problem of high price for single-layer material...
