[0018] like Figure 1-3 As shown, a feeding device for producing ultraviolet radiation cross-linked insulating materials includes a material collecting tray 1, the bottom of which is funnel-shaped and connected to an adjusting sleeve 2, and a supporting leg 10 is connected to the outer wall of the bottom of the material collecting tray 1.

[0019] The interior of the material collecting tray 1 is provided with a feeding pipe 3 with a sealed upper end, and a slider 4 is connected to the bottom of the feeding pipe 3. The slider 4 is slidably connected to the adjusting sleeve 2 through a sliding assembly. The sliding assembly includes a slide rail 11 installed on the inner wall of the adjusting sleeve 2. A slide groove 12 is provided on the side wall of the slider 4. The slider 4 is slidably connected to the slide rail 11 through the slide groove 12. The side wall of the slider 4 fits with the inner wall of the adjusting sleeve 2 to ensure that the insulating material will not fall through the gap between the slider 4 and the adjusting sleeve 2.

[0020] The feeding pipe 3 is connected to the gathering tray 1 through a lifting assembly, and the feeding pipe 3 is controlled to rise and fall by the lifting assembly. The lifting assembly includes two symmetrically arranged mounting frames 13, and the bottom of the mounting frames 13 is connected to the top surface of the gathering tray 1. A hydraulic cylinder 14 is connected to the mounting frame 13, and the telescopic end of the hydraulic cylinder 14 is vertically downwardly connected to a linkage rod 15. A fastener 16 is provided between the two linkage rods 15, and the fastener 16 is fixed to the tube body of the feeding pipe 3.

[0021] A spiral rod 5 is installed inside the feeding tube 3. The bottom of the spiral tube 5 is rotatably connected to the slider 4 through a sealed bearing 6. The spiral rod 5 is driven by a motor 7 installed on the top of the feeding tube 3. A feed port 8 is provided on the bottom side wall of the feeding tube 3, and a discharge port 9 is provided on the top side wall of the feeding tube 3.

[0022] When the height of the discharge port 9 needs to be adjusted, the telescopic end of the hydraulic cylinder 14 extends to control the lowering of the feeding pipe 3, and the slider 4 slides downward in the adjusting sleeve 2, thereby adjusting the height of the feeding pipe 3.

[0023] A material guide assembly is provided on the outside of the discharge port 9, and the material guide assembly includes a material guide plate 17. One end of the material guide plate 17 is connected to the wall of the feeding tube 3 below the discharge port 9, and the other end of the material guide plate 17 is inclined downward.
