[0034] See attached document Figure 1-5 A cable extrusion apparatus, comprising:

[0035] The base 1 has a support plate 19, a support plate 20 and a support plate 31 vertically mounted on it; the support plate 19 is equipped with a motor 22, the support plate 20 has a clearance hole in the middle, and the support plate 3 has an arc groove at the top.

[0036] The extrusion tube 2 is located above the base 1. One end of it passes through the clearance hole and is fixed on the support plate 19, while the other end rests on the slot, which can keep the extrusion tube 2 stable. The extrusion tube 2 is equipped with a spiral extrusion rod. One end of the spiral extrusion rod is connected to the output shaft of the motor 22, which can extrude the molten raw material from the other end under the drive of the motor 22.

[0037] Mounting base 23 is erected above support plate 19 and support plate 20, and has a clearance groove 24 in its middle. Mounting base 23 is equipped with support frame 25, and the top plate of support frame 25 has a clearance groove 2 in its middle. The top plate of support frame 25 has four outwardly extending load-bearing plates 27 on its side. The end of the load-bearing plate 27 away from the material cylinder 3 has a vertical support column 28. The bottom of the support column 28 is fixed to mounting base 23, which can keep its top plate stable and facilitate the subsequent placement and fixing of material cylinder 3.

[0038] The material cylinder 3 is located above the feed end of the extrusion tube 2, and its bottom is provided with a feed hopper 4 that connects to the extrusion tube 2; the top of the material cylinder 3 is provided with a cover plate 5, and the feed hopper 6 is provided on the cover plate 5; the outer wall of the material cylinder 3 is provided with an annular positioning plate 26, and the positioning plate 26 is fixed to the support frame 25 by bolts; the lower half of the material cylinder 3 passes through the second clearance groove and the first clearance groove 24 from top to bottom.

[0039] The mixing assembly, located inside the material cylinder 3, includes a motor 7, a mixing shaft 8, and an inclined wheel plate 9. The motor 7 is located on the cover plate 5, and its output shaft passes downward through the cover plate 5. The mixing shaft 8 is equipped with multiple sets of mixing blades 10, the top of which is connected to the output shaft of the motor 7. When the motor 7 is started, it can drive the mixing blades 10 to mix the raw materials in the material cylinder 3. The inclined wheel plate 9 is located on the mixing shaft 8, and its side wall is separated from the inner wall of the material cylinder 3 to facilitate the raw materials falling through the gap. The inclined wheel plate 9 has a fan-shaped discharge port 30 to accelerate the efficiency of the raw materials falling. However, the uppermost part of the discharge port 30 does not exceed the middle of the inclined wheel plate 9, so that the inclined wheel plate 9 retains at least half of its area to temporarily block the falling raw materials. This not only serves as a buffer but also prevents the raw materials from falling too quickly and reduces the phenomenon of accumulation and blockage.

[0040] The unblocking assembly includes two symmetrically arranged guide tubes 11 and one guide plate 12. The guide tubes 11 are vertically fixed to the inner wall of the material cylinder 3, and each has a guide rod 13 extending through its top and bottom. A slide block 14 and a compression spring 15 are mounted on the guide rod 13. The slide block 14 is fixed to the guide rod 13 and slides within the inner cavity of the guide tube 11. One end of the compression spring 15 rests against the bottom of the guide tube 11, and the other end rests against the bottom of the slide block 14. A contact seat 16 is located at the top of the guide rod 13, and the contact seat 16 is flush with the bottom of the inclined wheel plate 9. The part contacts and is subjected to the downward pressure applied by the inclined wheel plate 9, thereby driving the guide rod 13 to move downward; the two guide rods 13 move up and down synchronously, and the two ends of the guide plate 12 are respectively connected to the bottom of the guide rod 13 at the corresponding position. Below it, a clearing ring plate 18 is connected through multiple connecting rods 17. The clearing ring plate 18 can move downward to the connection between the feed hopper 4 and the extrusion tube 2 under the drive of the guide rod 13, so as to scrape off the raw material adhering to the connection between the feed hopper 4 and the extrusion tube 2 and clear the feed channel.

[0041] In this embodiment, a rotating roller 29 is provided at the top of the abutment seat 16; two rotating rollers 29 alternately contact the bottom edge of the inclined wheel plate 9. Due to the elastic force of the compression spring 15 on the slide seat 14 on the guide rod 13, the guide rod 13 moves vertically upward along the guide tube 11 until the rotating roller 29 at the top of the abutment seat 16 contacts the bottom of the inclined wheel plate 9. When the motor 7 starts and drives the stirring shaft 8 and the inclined wheel plate 9 to rotate, different heights of the bottom of the inclined wheel plate 9 contact the rotating roller 29, allowing the guide rod 13 to move up and down as the inclined wheel plate 9 rotates. It is easy to understand that when one side of the rotating roller 29 contacts the center height of the inclined wheel plate 9, an exchange is completed. At this time, the other side of the rotating roller 29 contacts the center height of the other side of the inclined wheel plate 9. When the inclined wheel plate 9 continues to rotate, its bottom will continue to contact the other side of the rotating roller 29, causing the other side of the guide rod 13 to move up and down. The rotating roller 29 that was in contact with the inclined wheel plate 9 before will no longer contact the inclined wheel plate 9, but will move up and down with the other side of the guide rod 13.

[0042] It should be noted that the guide plate 12 has a relief groove 31 in the middle for the bottom of the stirring shaft 8 to pass through. The inner wall of the relief groove 31 does not contact the stirring shaft 8, thus preventing the rotating stirring shaft 8 from causing wear to the guide plate 12. On the other hand, when the unblocking ring plate 18 rises with the guide plate 12, some raw material may adhere to the inner side of the unblocking ring plate 18. When the unblocking ring plate 18 rises to the height of the bottom of the stirring shaft 8, the rotating stirring shaft 8 will contact the raw material adhering to the inner side of the unblocking ring plate 18 and remove the adhering raw material by rapid rotation, thus preventing it from being removed from the inner side of the unblocking ring plate 18 in the next cycle.

[0043] The cable extrusion device of this utility model, through the stirring component and the unblocking component inside the barrel 3, can simultaneously clear the connection between the feeding hopper 4 and the extrusion pipe 2 during the feeding process, avoiding the long-term adhesion of raw materials to the connection between the feeding hopper 4 and the extrusion pipe 2, and preventing the situation where the outlet of the feeding hopper 4 is blocked due to the adhesion of raw materials. It is conducive to the normal passage of raw materials through the feeding hopper 4 into the extrusion pipe 2, so that the subsequent cable extrusion operation can proceed smoothly. It is very practical and has good market application prospects.

[0044] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
