A connecting part is installed on the outside of the tube shell half near the hinge seat. The connecting part is rotatably connected to the hinge seat.
[0009] Furthermore, the two ends of the tube shell half are inclined and fit against the two ends inside the groove, and the axes of the inner and outer sides of the tube shell half coincide with the axes of the inner and outer sides of the feeding pipe.
[0010] Furthermore, a mounting hole is provided at one end of the tube shell half near the insertion hole, the axis of the mounting hole coincides with the axis of the insertion hole, and a movable groove is provided in the center of the inner side of the mounting hole, which penetrates the tube shell half and faces the outer side of the tube shell half.
[0011] Furthermore, the pin is slidably connected to the inside of the mounting hole and inserted into the insertion hole, and a handle is integrally formed on the outside of the pin, the handle passing through the movable groove.
[0012] Furthermore, the outer side of the tube shell half, away from the hinge seat, is integrally formed with a discharge port.

[0022] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.
[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0024] Please see Figure 1-5 This utility model discloses a PVC sheath material formula metering and feeding device, including a hopper 1 and a feeding pipe 2 at the discharge end of the integrally molded hopper 1. The outer side of the feeding pipe 2 is provided with a groove 21 extending towards both ends. A sealing pipe shell half 4 is installed on the inner side of the groove 21. The pipe shell half 4 and the feeding pipe 2 are spliced to form a complete pipe. One end of the pipe shell half 4 is hinged to the outer side of the feeding pipe 2, and the other end of the pipe shell half 4 is slidably connected to a pin 6. The pin 6 is inserted and fixed to the feeding pipe 2.
[0025] Please see Figure 2 The two ends of the inner wall of the slot 21 are inclined and unfolded towards the outside of the feeding pipe 2. One end of the inner wall of the slot 21 is provided with an insertion hole 22. The inclined unfolding of the two ends of the inner wall of the slot 21 provides a guiding effect for the installation of the tube shell half 4, making it easier to form a seal when the tube shell half 4 is connected with the slot 21, and ensuring the alignment accuracy when the slot 21 and the tube shell half 4 are assembled.
[0026] Please see Figure 1A hinge seat 3 is fixedly connected to the outside of the feeding pipe 2. The hinge seat 3 is located at the end of the slot 21 away from the insertion hole 22. A connecting part 41 is installed on the outside of the pipe shell half 4 near the hinge seat 3. The connecting part 41 is rotatably connected to the hinge seat 3. The hinge structure reduces wear on components caused by frequent disassembly and assembly, and lowers maintenance costs. The pipe shell half 4 is closed and opened by rotating in cooperation with the slot 21. When the pipe shell half 4 and the feeding pipe 2 are closed and assembled, they are spliced into a complete pipe body for conveying raw materials. When the pipe shell half 4 is opened on the outside of the feeding pipe 2, the slot 21 can expose the inside of the feeding pipe 2, which is convenient for cleaning and maintenance of the feeding pipe 2 and its internal feeding structure. The two ends of the pipe shell half 4 are... The tube shell half 4 is inclined and fits into the inner two ends of the groove 21. The axes of the inner and outer sides of the tube shell half 4 coincide with the axes of the inner and outer sides of the feeding pipe 2. The inclined design of the two ends of the tube shell half 4 fits into the inclined surfaces of the inner walls of the groove 21, eliminating splicing gaps and preventing materials from getting stuck in the joints and causing sealing failure. This further improves the sealing performance when the tube shell half 4 and the groove 21 are assembled. The axis coincidence design of the tube shell half 4 and the feeding pipe 2 ensures that the pressure on the inner and outer sides is evenly transmitted to the pin 6 and the hinge seat 3 when closed, avoiding deformation due to force on one side and extending the service life of the pipe. At the same time, it also ensures the smooth connection between the tube shell half 4 and the inner wall of the feeding pipe 2, without affecting the feeding structure and the smooth movement of materials in the feeding pipe 2.
[0027] Please see Figure 5 The end of the tube shell half 4 near the insertion hole 22 has a mounting hole 5. The axis of the mounting hole 5 coincides with the axis of the insertion hole 22. A movable groove 51 is provided in the center of the inner side of the mounting hole 5, which passes through the tube shell half 4. The movable groove 51 faces the outer side of the tube shell half 4. The pin 6 is slidably connected to the inner side of the mounting hole 5 and is inserted into the insertion hole 22. The outer side of the pin 6 has an integrally formed handle 61, which passes through the movable groove 51. The combination of the mounting hole 5 and the movable groove 51 makes it convenient for the staff to control the movement of the pin 6 by the handle 61 without the need for additional tools. The pin 6 naturally aligns with the insertion hole 22 during the sliding process, which simplifies the locking process. The pin 6 realizes quick fixing or disassembly with a push and pull, which is suitable for scenarios with frequent maintenance.
[0028] Please see Figure 1 The outer side of the tube shell half 4, away from the hinge seat 3, has an integrally formed discharge port 42. The discharge port 42 is integrally formed with the tube shell half 4, which reduces the resistance to material flow and effectively avoids material accumulation or blockage.
