[0028] Specifically, such as Figure 1 and Figure 2 As shown, collagen PU composite medical membrane materials are typically polyurethane resin particles. After multiple materials are precisely proportioned digitally, they need to be gradually melted, plasticized, and mixed through shearing and extrusion by a screw. Common extrusion equipment has a limited length, and when the heating temperature is unstable, it is easy to cause insufficient melting. By opening a second discharge port 10 on the right side of the bottom end of the tube body 1, opening the first solenoid valve 12 and the second solenoid valve 13, and starting the pneumatic diaphragm pump 14 from the control seat 8, the material solution enters the tube body 1 through the second discharge port 10 and, under the action of the pneumatic diaphragm pump 14, through the first connecting pipe 15, the second connecting pipe 16, and finally through the second discharge port 10, thereby achieving reheating and melting of the material and thus achieving full mixing of the material.

[0029] A second servo motor 17 is fixedly connected to the left side of the first feed port 5. A movable shaft 18 is movably connected inside the first feed port 5. A rotating blade 19 is wrapped around the outside of the movable shaft 18. The output end of the second servo motor 17 is connected to the movable shaft 18. The second servo motor 17 is electrically connected to the control base 8.
[0030] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, during use, the second servo motor 17 is started by the control base 8. The second servo motor 17 drives the rotation of the movable shaft 18. The outer side of the movable shaft 18 is fitted with a rotating blade 19. The rotating blade 19 is designed with equal angles. When the movable shaft 18 rotates, it drives the material to enter the tube 1 in a regular manner, thereby avoiding uneven heating caused by different material inputs.

[0031] A mounting base 20 is fixedly connected to the right side of the top end of the tube body 1. An observation window 21 is installed inside the mounting base 20. The observation window 21 is made of transparent material and allows observation of the inside of the tube body 1.
[0032] Specifically, such as Figure 1 and Figure 2 As shown, during use, a mounting base 20 is fixedly connected to the right side of the top of the tube body 1. An observation window 21 is installed inside the mounting base 20. The observation window 21 is located on the right side of the heating module 9. The operator can observe the inside of the tube body 1 through the observation window 21, thereby monitoring the degree of melting of the material inside the tube body 1.
[0033] Working Principle: In use, the collagen PU composite medical membrane material is typically composed of polyurethane resin particles. After precise digital proportioning of various materials, they need to be gradually melted and plasticized through shearing and extrusion by a screw. Common extrusion equipment has limited length, and when the heating temperature is unstable, incomplete melting can easily occur. By opening a second discharge port 10 on the right side of the bottom of the tube 1, opening the first solenoid valve 12 and the second solenoid valve 13, and starting the pneumatic diaphragm pump 14 from the control seat 8, the material solution passes through the second discharge port 10. Under the action of the pneumatic diaphragm pump 14, it flows from the first connecting pipe 15, the second connecting pipe 16, and finally back into the tube 1 through the second discharge port 10, thereby achieving the desired melting process. The material is reheated and melted to achieve thorough mixing. Next, the second servo motor 17 is started by the control seat 8, which drives the rotation of the movable shaft 18. The outer side of the movable shaft 18 is fitted with a rotating blade 19, which is designed at equal angles. When the movable shaft 18 rotates, it drives the material into the tube 1 in a regular manner, thereby avoiding uneven heating caused by different material inputs. At the same time, the mounting seat 20 is fixedly connected to the right side of the top of the tube 1. The mounting seat 20 is equipped with an observation window 21, which is located on the right side of the heating module 9. The operator can observe the inside of the tube 1 through the observation window 21 to monitor the degree of melting of the material inside the tube 1.
