Description

Technical Field

[0001] This utility model relates to the field of medical catheter extrusion, specifically a medical catheter extrusion production line. Background Technology

[0002] A medical catheter extrusion production line is a specialized production line for producing medical plastics and their composite materials. It integrates an extruder, cooling equipment, and other related auxiliary equipment, specifically designed for the continuous and efficient production of various plastic products, such as pipes, sheets, films, and shaped materials. The "Medical Catheter Extrusion Production Line" disclosed in application number "CN213321564U" represents an increasingly mature technology. The invention describes a medical catheter extrusion production line where, by first extending the first and second telescopic frames and pulling the fixing pin, the first and second telescopic frames are matched and have equal ground clearance because the fixing pin does not penetrate the second telescopic frame under spring compression. The first telescopic frame can then be engaged inside the second telescopic frame. Afterward, the fixing pin is no longer applied, allowing the spring to return to its natural state. The fixing pin can penetrate through one set of housings and one set of second telescopic frames to find a suitable position. The fixing pin can also penetrate through the first telescopic frame that is engaged inside the second telescopic frame, thus fixing the cooling water tank and the extruder, preventing them from easily shifting and thus preventing damage to the catheter production. However, this production line still has the following drawbacks during use: While the production line, through its structure of first telescopic frame, second telescopic frame, fixing pin, cooling water tank, and extruder, can indeed perform the extrusion operation of medical catheters, its simple structure makes it inconvenient to integrate cooling, diameter measurement, traction cutting, and feeding after extrusion, thus affecting the extrusion efficiency of the production line. Therefore, it is necessary to provide a production line that can facilitate the simultaneous extrusion, cooling, diameter measurement, traction cutting, and feeding of medical catheters in one operation, thereby improving production efficiency.

[0059] Working principle: In use, the plastic material is first placed in the storage hopper 1032. Then, the first motor 1021 is started, and the first reduction gearbox 1022 drives the feeding screw 1023 to rotate, thus conveying the plastic material. Subsequently, the plastic material is heated and plasticized by the heater 1024. After being extruded through the extrusion die, the plastic tube falls into the vacuum water tank 2022 filled with water. At this time, the vacuum pump 2013 is started to draw a vacuum, which can perform online cooling and vacuum shaping of the hollow tube. At the same time, the diameter is measured. Instrument 302 can monitor the outer diameter of hollow round tubes in real time. Then, the second motor 4021 is started to work with the belt traction mechanism 4023 to clamp and pull the tubes backward. The tubes are then cut into equal-distance sections by the cutting mechanism 4024. The cut products are then conveyed backward. At this time, the fourth motor 5012 is started to drive the first transmission wheel 5013 to rotate, and the second transmission wheel 5015 drives the conveyor belt 5016 to rotate. This enables the tubes to be conveyed and automatically counted, thereby significantly improving the production efficiency of the extrusion production line.
