After rotating to an appropriate angle, the fastening limit nut 15 is fixed. The angle adjusted by the adjusting plate 8 can control the feeding speed of the cable raw material in the storage frame 12, so that the speed of the cable raw material falling into the feeding cylinder 2 can be controlled, and the problem of blockage caused by too much cable raw material entering the feeding cylinder 2 can be avoided.

[0026] Embodiment 2

[0027] On the basis of Embodiment 1, a feeding cylinder 2 is provided for facilitating the feeding of the cable raw material. The installation frame 4 is fixedly connected to the end face of the feeding cylinder 2, the driving motor 5 is fixedly connected to the inner side face of the installation frame 4, the transmission end of the driving motor 5 is fixedly connected to the end face of the spiral feeding paddle 3, and a discharge frame 10 is arranged on the lower surface of the feeding cylinder 2;

[0028] When in use, after the cable raw material is fed into the feeding cylinder 2, the driving motor 5 can be started to drive the spiral feeding paddle 3 to rotate, so that the cable raw material can be discharged from the discharge frame 10 into the extruder for processing by the rotation of the spiral feeding paddle 3, avoiding the need for staff to continuously pour the cable raw material into the extruder.

[0029] When it is necessary to clean the inside of the feeding cylinder 2, a sealing cover 11 is provided. The sealing cover 11 is provided at one end of the feeding cylinder 2. The sealing cover 11 can seal the bottom of the feeding cylinder 2. The cable raw material can enter the feeding cylinder 2 from the feeding frame 6. When the inside of the feeding cylinder 2 needs to be cleaned, the sealing cover 11 can be directly rotated to separate the sealing cover 11 from one end of the feeding cylinder 2, so that it is more convenient to clean the inside of the feeding cylinder 2.

[0030] Embodiment III

[0031] On the basis of Embodiment II, in order to conveniently control the flow rate of the cable raw material and avoid clogging the inside of the feeding cylinder 2, a regulating plate 8 is provided. There are multiple groups of support rods 7, and the multiple groups of support rods 7 are linearly arranged at equal intervals in the feeding frame 6. The regulating plate 8 is in the shape of a square plate. The traction wheels 9 sleeved on each group of support rods 7 are driven by a traction belt 14. Threads are provided on the surface of one group of support rods 7, and a limit nut 15 is screwed on the threads. A storage frame 12 is provided on the surface of the feeding frame 6. A hole is provided on the side surface of the feeding frame 6, and a bearing 13 is provided in the hole. The support rod 7 is fixedly connected to the inner ring surface of the bearing 13;

[0032] During use, the support rod 7 can be rotated in cooperation with the bearing 13, so that the regulating plate 8 in the feeding frame 6 can be rotated. The feeding speed of the cable raw material can be controlled by the amplitude of the rotation angle of the regulating plate 8, so as to avoid the problem of the cable raw material clogging the inside of the feeding cylinder 2.

[0033] In order to conveniently position the rotating support rod 7, a limit nut 15 is provided. A limit plate 16 is provided on the side surface of the feeding frame 6.

[0034] During use, the limit nut 15 can be rotated to make the limit nut 15 fit with the damping ring 17 and be fastened to the side surface of the limit plate 16. Through the setting of the damping ring 17, the friction force of the limit nut 15 on the limit plate 16 can be increased, and the stability of fixing the support rod 7 can be improved.

[0035] During actual use, the rotation of the support rod 7 can be combined with the setting of the traction belt 14 to rotate the adjusting plate 8 in the blanking frame 6. After rotating to an appropriate angle, the fastening limit nut 15 is fixed. The angle adjusted by the adjusting plate 8 can control the blanking speed of the cable raw material in the storage frame 12, so as to control the speed at which the cable raw material falls into the feeding cylinder 2, and avoid the problem of blockage caused by too much cable raw material entering the feeding cylinder 2. This avoids the problem that the length of the feeding cylinder 2 of general feeding equipment is relatively long, and it is impossible to prevent the raw material from being blocked in the feeding cylinder 2 when feeding the cable. After the feeding cylinder 2 is blocked, the staff needs to disassemble the equipment for cleaning, which not only increases the work intensity of the staff but also hinders the normal working efficiency of the extruder.
