[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses a feed distributor for a multi-layer co-extrusion blown film machine. For example... Figure 2 and Figure 4 As shown, the device includes a body 1. A set of annularly arranged discharge pipes 2 are fixedly connected to the outer surface of the body 1. A main feed pipe 4 is fixedly connected to the inner top wall of the body 1. A hopper 5 is fixedly connected to the top of the main feed pipe 4. A feed diversion pipe 10 is rotatably connected to the bottom of the main feed pipe 4. A pressure sensor 11 is fixedly embedded on the outer surface of the feed diversion pipe 10. The sensing end of the pressure sensor 11 is located inside the feed diversion pipe 10, which can effectively monitor and control the material pressure inside the feed diversion pipe 10, ensuring that the material is evenly distributed to each discharge pipe 2. The bottom of each discharge pipe 2 is fixedly connected to... Each discharge pipe 2 is equipped with a connecting flange 14, and each connecting flange 14 has a set of annularly arranged connecting holes 15 on its bottom surface. Each discharge pipe 2 has a regulating valve 16 installed on its inner wall, which enables convenient connection between the discharge pipe 2 and subsequent processing equipment. The design of the connecting flange 14 increases the stability and sealing of the connection, preventing material leakage. At the same time, the setting of the connecting holes 15 makes it easy to use bolts or other fasteners to firmly connect the discharge pipe 2 to the subsequent equipment. The installation of the regulating valve 16 can flexibly adjust the discharge volume of each discharge pipe 2, further ensuring the uniformity and accuracy of material distribution and meeting different production needs.

[0022] Please see Figure 2 and Figure 3An adjustment box 3 is fixedly connected to the bottom surface of the machine body 1. Symmetrical battery modules 12 are fixedly connected to the inner bottom wall of the adjustment box 3. Positioning plates 13 are fixedly connected to the front and back of each battery module 12. The bottom surface of each positioning plate 13 is fixedly connected to the inner bottom wall of the adjustment box 3, ensuring the stable installation of the battery modules 12 within the adjustment box 3 and preventing them from shaking or shifting during operation. This improves the operational stability and reliability of the entire feed distributor. The design of the battery modules 12 provides continuous power support for the entire equipment, ensuring the normal operation of electronic components such as the pressure sensor 11 and the regulating valve 16. Positioning plates 1... The use of 3 not only enhances the connection strength between the battery module 12 and the regulating box 3, but also facilitates the installation and maintenance of the battery module 12. A set of equidistant heat dissipation windows 17 are provided on the back of the regulating box 3. Each heat dissipation window 17 has a dustproof net fixedly connected to its inner wall, which can effectively prevent dust from entering the interior of the regulating box 3 and avoid dust from damaging electronic components such as the battery module 12, thereby extending the service life of the entire feed distributor. The design of the heat dissipation windows 17 can also improve the heat dissipation effect inside the regulating box 3, ensuring that the battery module 12 will not malfunction due to excessive temperature during operation, further improving the operational stability and reliability of the entire equipment.

[0023] Please see Figure 4 The inner top wall of the regulating box 3 and the inner top wall of the machine body 1 are jointly and fixedly embedded with a bearing 6. The inner wall of the bearing 6 is fixedly connected to a connecting shaft 7. The top end of the connecting shaft 7 is fixedly connected to a connecting piece 8. The outer surface of the connecting piece 8 is fixedly connected to the outer surface of the feed diversion pipe 10. The inside of the regulating box 3 is fixedly installed with a reduction motor 9. The output end of the reduction motor 9 is fixedly connected to the bottom end of the connecting shaft 7. The reduction motor 9 can drive the connecting shaft 7 to rotate. The connecting shaft 7 drives the feed diversion pipe 10 to rotate synchronously through the connecting piece 8. This design allows the feed diversion pipe 10 to be angled according to production needs, thereby achieving precise distribution of the feed amount of the multi-layer co-extrusion blown film machine.

[0024] Please see Figure 1 and Figure 2The bottom surface of the regulating box 3 is fixedly connected to a symmetrical frame 18. The two frames 18 are fixedly connected to a symmetrical reinforcing plate 19 on their adjacent sides. This design effectively improves the installation stability of the regulating box 3 and prevents it from shaking or shifting during operation. The reinforcing plate 19 not only enhances the connection strength between the frames 18 but also makes the entire feed distributor structure more robust and durable. The front of the regulating box 3 is hinged to a door 20, and a touch control screen 21 is fixedly installed on the front of the door 20. With this design, the user can control the geared motor 9 through the touch control screen 21 to adjust the rotation angle of the feed diversion pipe 10. The touch control screen 21 has an intuitive operating interface and rich function options, allowing the user to easily complete various settings and adjustments.

[0025] The implementation principle of the feed distributor of a multi-layer co-extrusion blown film machine according to this application embodiment is as follows: During operation, different raw materials required for the production of the multi-layer co-extrusion blown film machine are sequentially poured into the hopper 5. The raw materials enter the feed distribution pipe 10 through the main feed pipe 4. At this time, the reduction motor 9 works, and the output end of the reduction motor 9 drives the connecting shaft 7 to rotate. The connecting shaft 7 drives the connecting part 8 and the feed distribution pipe 10 to rotate in the bearing 6. Through the rotation of the feed distribution pipe 10, the raw materials can be evenly distributed into each discharge pipe 2. At the same time, the pressure sensor 11 senses the pressure in the feed distribution pipe 10 and transmits the pressure data to the touch control screen 21 for display. When the pressure data is abnormal, the operator can close the corresponding regulating valve 16 through the touch control screen 21 to prevent the device from being damaged. The battery module 12 provides power to the geared motor 9 and the touch control screen 21. The positioning plate 13 positions the battery module 12 to prevent it from shaking during use. The discharge pipe 2 can be connected to other components of the multi-layer co-extrusion blown film machine through the connecting flange 14 and the connecting hole 15. The regulating valve 16 can control the discharge volume of the discharge pipe 2. The design of the heat dissipation window 17 and the dustproof net can improve the heat dissipation effect of the regulating box 3 and prevent dust from entering the regulating box 3. The frame 18 and the reinforcing plate 19 can improve the stability of the regulating box 3. The design of the box door 20 makes it convenient for staff to inspect the inside of the regulating box 3. The touch control screen 21 can control the opening and closing of the geared motor 9 and display the data transmitted by the pressure sensor 11.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
