The drainage tube is generally made of materials such as silicone rubber or polyurethane. When in use, one end of the catheter is inserted into the drainage part of the body or wound surface, and the other end can be connected to other external devices such as a drainage adapter outside the body, and drains to the outside through the action of pressures such as internal pressure, gravity, or negative pressure suction.

[0003] For example, an extruder for processing a special-shaped drainage tube disclosed in a Chinese patent with the publication number CN214056350U. It includes an extruder body, a fixed disk, and a movable disk. The top of the extruder body is connected to an extrusion tube through a feeding tube, and the extrusion tube is installed on the top of the extruder body; the fixed disk is installed at one end of the extrusion tube; the movable disk is installed on one side of the fixed disk. There are a motor, a lead screw, a sliding sleeve, a sliding rod, and a movable disk. The motor drives the lead screw to rotate, and the lead screw cooperates with the sliding sleeve to drive the whole movable disk to slide left and right along the horizontal line. The four sliding rods ensure that the movable disk remains stable during sliding. The movement of the movable disk facilitates the quick disassembly of the die head, improves the practicability, and ensures the continuity of the overall processing.

[0004] In the process of implementing this application, the inventor found that there are at least the following problems in this technology: Although the above technical solution can quickly complete the disassembly of the die head and ensure the continuity of the overall processing, the extruded drainage tube cannot be cut into a specified length according to the use needs and still requires manual cutting, which will affect the efficiency. Therefore, further improvement can be made. Content of the Utility Model

The right end of the material extrusion tube 2 is provided with a die head 3. A sliding roller 4 is fixedly installed on the right side surface of the die head 3 and directly below the die head 3. A cooling and conveying assembly 5 for conveying and accelerating the cooling and forming of the drainage tube is arranged on the right side of the extruder 1. A fixed-length cutting assembly 6 for cutting the formed drainage tube is arranged on the right side of the cooling and conveying assembly 5.

[0024] Please refer to Figure 2 , the cooling and conveying assembly 5 includes two groups of symmetrically arranged brackets 7 fixedly installed on the right side of the extruder 1. A square tube 8 is fixedly installed on the top of the bracket 7. A rotating roller 9 is rotatably connected between the two square tubes 8 on both sides. The rotating roller 9 and the sliding roller 4 are located on the same horizontal plane, and five rotating rollers 9 are arranged between the two square tubes 8 on both sides. The extrusion of the drainage tube is conveniently conveyed through the rotating roller 9;

[0025] Please refer to Figure 2 , an air guide tube 10 is fixedly communicated with the outside of one end of the square tube 8 close to the material extrusion tube 2. The cooling and conveying assembly 5 further includes a cold air machine, and the end of the air guide tube 10 away from the square tube 8 is led into the air outlet of the cold air machine. A plurality of air outlet holes 11 are opened on the opposite side surfaces of the two square tubes 8 on both sides. One air outlet hole 11 is located between every two adjacent rotating rollers 9. By starting the cold air machine, cold air is transmitted into the square tube 8 along the air guide tube 10, and then blows out from the air outlet holes 11 to cool and lower the temperature of the just-extruded drainage tube, accelerating its forming;

[0026] Please refer to Figures 3-4 , the fixed-length cutting assembly 6 includes a vertical frame 12 arranged on the right side of the extruder 1. A connecting frame is fixedly installed on one side of the needle tube of the vertical frame 12, and a servo motor 13 is fixedly installed inside the connecting frame. A main gear 14 and a driven gear 15 are rotatably connected to the top of the vertical frame 12, and the main gear 14 and the driven gear 15 are meshed. A rotating shaft is fixedly installed at the center of the main gear 14, and the output shaft of the servo motor 13 and the rotating shaft are fixedly installed. By starting the servo motor 13, the rotating shaft will be driven to rotate, and then the driven gear 15 meshed with the main gear 14 will be driven to rotate synchronously, so that the corresponding cutter holders 17 in the main gear 14 and the driven gear 15 are butted, and thus the drainage tube passing through between the main gear 14 and the driven gear 15 is cut;

[0027] Please refer toFigures 3-4 On both sides of the inner walls of the main gear 14 and the driven gear 15, mounting holes 16 are provided. A cutter holder 17 is installed in the middle of the main gear 14 and the driven gear 15 through the mounting holes 16. Insertion holes 18 are provided inside both sides of the cutter holder 17. A pin head 19 is slidably inserted into the insertion holes 18. A spring 20 is fixedly installed between the pin head 19 and the inner wall of the insertion hole 18. A blade 21 is fixedly installed inside the middle of the cutter holder 17. The retractable spring 20 facilitates the insertion of the pin head 19 into the mounting hole 16, thereby facilitating the installation and disassembly of the cutter holder 17, so that the positions of the two groups of cutter holders 17 can be adjusted according to actual needs, and then the quantitative length of the drainage tube cutting can be adjusted.

[0028] During use, first, the drainage tube is extruded through the extrusion tube 2. The extruded drainage tube will be conveyed forward along the roller 9. At the same time, cold air will be conveyed into the square tube 8 along the air duct 10 through the air conditioner and discharged outwards from the air outlet 11. Then, while the drainage tube is being conveyed forward, it will be cooled by the cold air, accelerating the formation of the drainage tube.

[0029] The drainage tube formed after cooling and temperature reduction will pass forward through between the main gear 14 and the driven gear 15. At this time, the main gear 14 is driven to rotate by the servo motor 13, and then the driven gear 15 will rotate synchronously with the main gear 14. Therefore, the cutter holders 17 on both sides will rotate relatively. When the cutter holders 17 on both sides are butted together, the drainage tube is cut to a fixed length by the blade 21.

[0030] Among them, the retractable spring 20 enables the pin head 19 to enter and exit along the inner wall of the insertion hole 18, thereby facilitating the installation and disassembly of the cutter holder 17. Therefore, it is convenient to adjust the position of the cutter holder 17, and then the quantitative length of the drainage tube cutting can be adjusted according to actual needs.

[0031] In summary, for this drainage tube processing device and the drainage tube, cold air is conveyed into the square tube 8 through the air duct 10 and then discharged outwards from the air outlet 11. Then, the drainage tube being conveyed on the roller 9 is cooled, accelerating the formation of the drainage tube. Then, the driven gear 15 rotates relatively by driving the main gear 14 to rotate, causing the cutter holders 17 on both sides to rotate relatively and butt together. Then, the drainage tube is cut to a fixed length by the blade 21, thereby improving the processing efficiency of the drainage tube.

[0032] By pressing the pin head 19, the spring 20 will be compressed, and then the pin head 19 can enter and exit along the inner wall of the insertion hole 18. So, it is convenient to disassemble and install the cutter holder 17, and the position of the cutter holder 17 can be adjusted. By adjusting the corresponding positions of the two groups of cutter holders 17, the cutting length of the drainage tube can be changed, and thus the quantitative length of the drainage tube cutting can be adjusted according to actual needs.
