[0030] Reference is made to Figure 1 , Figure 2 and Figure 3The utility model provides an automatic cable insulation material feeding device, which comprises a storage tank 1 for storing material, a conical bottom tank 2 welded to the bottom of the storage tank 1, a discharge pipe 3 arranged at the bottom axis of the conical bottom tank 2 and connected with the feeding port flange of an extruding machine, a feeding groove 11 formed at the side of the storage tank 1 near the top, a feeding hopper 12 welded to the side of the storage tank 1 and connected with the feeding groove 11, a tank cover 4 detachably installed at the top of the storage tank 1, a sliding pipe 5 installed through the tank cover 4, a linear bearing 6 matched between the sliding pipe 5 and the tank cover 4, a discharging device 7 matched through the sliding pipe 5, a support 8 fixed to the outer wall of the sliding pipe 5, and two synchronous servo push rods 9 installed at the top of the tank cover 4 and fixed to the support 8.
[0031] In the above technical solution, the servo push rod 9 is controlled by a servo system, and the vertical displacement of the sliding pipe 5 can be accurately controlled through the servo push rod 9.
[0032] In the above technical solution, when the material in the storage tank 1 is blocked, the upward movement of the sliding pipe 5 drives the vertical displacement of the discharging device 7, the material in the storage tank 1 is loosened, and the blocked material is transported downward.
[0033] Referring to Figures 1 to 4 As shown, the discharging device 7 comprises a discharging shaft 71 and a discharging motor 72, the upper end of the discharging shaft 71 passes through the sliding pipe 5, a bearing 73 is matched between the discharging shaft 71 and the sliding pipe 5, a spiral blade 74 is welded to the lower part of the discharging shaft 71, the spiral blade 74 is matched with the discharge pipe 3, and the spiral blade 74 moves upward and then separates from the discharge pipe 3 as the sliding pipe 5 moves upward, the discharging motor 72 is installed through the support 8, and a transmission unit 75 is matched between the discharging motor 72 and the discharging shaft 71.
[0034] In the above technical solution, the height of the discharging shaft 71 changes with the sliding pipe 5, in the normal discharging process, part of the spiral blade 74 is located in the discharge pipe 3 and part of the spiral blade 74 is located in the conical bottom tank, the material is uniformly transported downward through the rotation of the discharging shaft 71 and the spiral blade 74.
[0035] When the material in the storage tank 1 is blocked, the upward movement of the discharging shaft 71 causes the spiral blade 74 to move upward and separate from the discharge pipe 3, in this movement process, the discharging motor 72 keeps rotating, at this time, the rotating spiral blade 74 loosens the material in the storage tank 1, after loosening, the material above collapses downward, and then the blockage is cleared.
[0036] After loosening, the discharging shaft 71 slowly moves downward, the spiral blade 74 is reset and continues to work.
[0037] The transmission unit is a belt transmission.
[0038] Referring to Figure 4 As shown in the drawings, a sealing body 771 is mounted on the blanking shaft 71, an upper end of the sealing body 771 is formed with a dispersing taper surface 772, the diameter of the dispersing taper surface 772 gradually increases downward, and a sealing taper surface 773 is formed on the outer wall of the sealing body 771. When the sliding pipe 5 slides to the limit position, the sealing taper surface 773 is in close contact with the inner wall of the conical bottom tank 2 to form a seal.
[0039] In the above technical solution, the sealing body 771 is designed, by changing the height of the blanking shaft 71, the distance between the sealing taper surface 773 and the conical bottom tank 2 can be adjusted, and then the blanking gap is adjusted to avoid the case that the blanking speed is too fast.
[0040] After the extrusion molding is completed, the blanking can be stopped by moving the blanking shaft 71 downward and cooperating the sealing body 771 with the conical bottom tank 2.
[0041] Referring to Figure 2 As shown in the drawings, a plurality of dispersing tapers 717 are distributed on the outer wall of the blanking shaft 71.
[0042] Since the upward height of the blanking shaft 71 is limited, the dispersing tapers 717 additionally arranged can reduce the plugging situation in the storage tank.
[0043] The diameter of the dispersing taper 717 gradually decreases away from the blanking shaft.
[0044] Referring to Figure 4 As shown in the drawings, the blanking shaft 71 is a hollow shaft, and the upper and lower ends of the blanking shaft are through.
[0045] In this technical solution, the top tank of the blanking shaft 71 can be used to supplement the material, especially when the material in the extruder is insufficient, the supplementing speed can be accelerated.
