It adopts advanced automated equipment and intelligent control systems, which can quickly adjust the production process and change product specifications and models according to different production needs, achieving efficient and high-quality production of various types and sizes of silicone tubes. During the production process, by precisely controlling the parameters of each link such as raw material transportation, mixing, extrusion, and vulcanization, combined with automated detection and feedback mechanisms, the production status is monitored and adjusted in real time to ensure the stability and consistency of product quality, while improving production efficiency, reducing production costs, and meeting the market's diverse and personalized demands for silicone tubes.

[0003] When producing silicone tubes, a raw material conveying tank is needed to transport the raw material to the extruder for extrusion.

[0029] Working Principle: During the production of silicone tubes, the operator pours the silicone rubber raw material into the raw material conveying tank 3, then starts the equipment. The stirring servo motor 6 starts, driving the hexagonal column 7 to rotate. The rotation of the hexagonal column 7 drives the stirring shaft 8 to rotate. The rotation of the stirring shaft 8 drives the two preheating supports 15 to rotate around the stirring shaft 8 as the center. The two preheating supports 15 drive the corresponding scrapers 16 to rotate. At the same time, the multiple heating tubes 17 set on the two scrapers 16 start to preheat the silicone rubber raw material and reduce its viscosity. The linkage servo motor 14 starts, driving the linkage wheel 13 to rotate. When the linkage wheel 13 rotates, the grooves on its surface are adapted to the two racks 12. Therefore, the rotational motion of the linkage wheel 13 is converted into the linear motion of the racks 12 through the meshing of the grooves and racks 12. The two racks 12 move in opposite directions, thus driving the linkage slider 11 to move through the movement of the racks 12. The movement of the linkage slider 11 drives the movement of two linkage rings 10, which in turn drives the movement of two lifting rings 9. The movement of the two lifting rings 9 drives the same stirring shaft 8 to move up and down, thereby expanding the cleaning range of the scraper 16 on the inner wall of the raw material conveying tank 3 and increasing the uniformity of the preheating of the silicone rubber raw material. After the silicone rubber raw material is preheated, the operator starts the quantitative servo motor 25. The quantitative servo motor 25 drives the worm gear 24 to rotate, which in turn drives the worm wheel 23 to rotate. The worm wheel 23 drives the hexagonal protrusion on the threaded rod 22 to rotate through its own hexagonal hole, which in turn drives the threaded rod 22 to rotate. The threaded rod 22 is adapted to the threaded groove on the inner side of the quantitative pipe 18. Therefore, the rotation of the threaded rod 22 drives the valve needle 21 to move away from the valve seat 20, thereby controlling the precise discharge of the silicone rubber raw material. The silicone rubber raw material enters the extruder 1 for extrusion production.

[0030] The technological advancements achieved by this invention compared to existing technologies are as follows: the raw materials can be preheated and stirred. Silicone rubber raw materials have high viscosity and poor fluidity at room temperature. Preheating can reduce their viscosity and enhance their plasticity, allowing them to pass more smoothly through the screw of the extruder during the extrusion process.
