[0028] Reference Figure 1-6 This utility model discloses a heat-resistant and high-strength polyethylene cable material preparation device, which includes: a support platform 1 and a mixing chamber 21. A vertical plate 10 is fixedly connected to the upper surface of the support platform 1 for mounting a rotating shaft 11 and a second motor 9. The rotating shaft 11 is rotatably connected to one side of the vertical plate 10, driving the mixing tank 12 to rotate. One end of the rotating shaft 11 is fixedly connected to the mixing tank 12 to premix the materials. A fixed box 26 is fixedly connected to the bottom of the mixing tank 12, which is connected to a moving plate 27 to form a sealing plate to prevent the materials from falling. The interior provides a sliding space for a control plate 28. The moving plate 27 is slidably connected to the middle of the side wall of the mixing tank 12 for premixing. When the material is mixed, the moving plate 27 is pulled to separate it from the fixed box 26 to complete the feeding. One end of the moving plate 27 is fixedly connected to the control plate 28, and a circular hole is provided in the middle. Pulling the moving plate 27 will cause the control plate 28 to be pulled out from the inside of the fixed box 26. The distance of pulling the moving plate 27 is adjusted according to the amount of material to be fed, thereby adjusting the area of ​​the circular hole of the control plate 28 so that the material can leak out from the circular hole. The upper surface of the support platform 1 is provided with a conveying chamber 15 to provide an installation place for the conveying roller 2. Two conveying rollers 2 are rotatably connected to the inner wall of the conveying chamber 15 to shear the material, enhance the mixing effect, and shorten the melting speed of the agglomerated material.

[0029] A stirring rod 20 is rotatably connected to the top of the mixing chamber 21, which drives the stirring blades 22 to rotate and thus mix the materials. Multiple stirring blades 22 are fixedly connected to the outside of the stirring rod 20 at intervals. Each stirring blade 22 has a spring 13 inside, which keeps the brush 8 in contact with the inner wall of the mixing chamber 21 by its own elasticity. A brush 8 is fixedly connected to one end of each spring 13 to brush off the material adhering to the inner wall of the mixing chamber 21 so that it can continue to participate in the mixing process.

[0030] A gear box 6 is provided on the outer wall of the conveying chamber 15 to provide an installation place for the gears 4. Two gears 4 are rotatably connected to the inner wall of the gear box 6. The two gears 4 mesh with each other and drive the conveying roller 2 to rotate. The central shafts of the two gears 4 are respectively fixedly connected to one end of the two conveying rollers 2.

[0031] A first motor 5 is provided on the outer wall of the gear box 6, which drives one of the gears 4 to rotate, thereby driving the other gear 4 to rotate, so as to realize the function of operating the two conveying rollers 2. The output end of the first motor 5 is fixedly connected to the side wall of one of the gears 4.

[0032] A fixed plate 30 is fixedly connected to the upper surface of the movable plate 27. The fixed plate 30 has a threaded hole in the middle, which cooperates with the bolt 29 to fix it to the side wall of the mixing tank 12. The control plate 28 is slidably connected to the inner wall of the fixed box 26. The fixed plate 30 is threadedly connected to the bolt 29 in the middle and the front end extends into the inside of the side wall of the mixing tank 12 and is threadedly connected to it.

[0033] The bottom of the mixing tank 12 is provided with an outlet 14, and the premixed material falls from the outlet 14 into the feed hopper 7. The top of the conveying chamber 15 is provided with a feed hopper 7, and the material enters the conveying chamber 15 from the feed hopper 7. The top of the mixing chamber 21 is provided with a liquid inlet 19, which is a channel for adding liquid materials. The upper end of the liquid inlet 19 is fitted with a protective cover 18 to prevent the material in the mixing chamber 21 from splashing out during operation.

[0034] A second motor 9 is installed on one side of the vertical plate 10, which drives the rotating shaft 11 to rotate the mixing tank 12 to achieve material premixing. The output end of the second motor 9 is fixedly connected to the rotating shaft 11. A third motor 16 is installed on the top of the mixing chamber 21, which drives the stirring rod 20 to rotate the stirring blade 22 to achieve the stirring effect. The output end of the third motor 16 is fixedly connected to one end of the stirring rod 20.

[0035] A heating plate 17 is provided in the middle of the side wall of the mixing chamber 21 to heat and melt the material in the mixing chamber 21. The connection between the conveying chamber 15 and the mixing chamber 21 is provided with a discharge port 3. The material is conveyed by the conveying roller 2 to the discharge port 3 and then falls into the mixing chamber 21. Support legs 23 are provided at the four corners of the bottom of the mixing chamber 21 to support the mixing chamber 21.

[0036] Both the inlet and outlet 25 of the mixing tank 12 are equipped with matching covers. The connection between the two covers and the inlet and outlet 25 of the mixing tank 12 is provided with clamps 24 to connect the covers and the openings.

[0037] Working principle: During use, open the protective cover 18 and directly add the required liquid material into the mixing chamber 21 through the inlet 19, then close the protective cover 18. Open the clamp 24 at the feed port of the mixing tank 12 and add various solid materials into the mixing tank 12. Then, close the feed port cover onto the mixing tank 12 and lock the feed in place with the clamp 24. Start the second motor 9 to drive the rotating shaft 11, causing the mixing tank 12 to rotate, thereby pre-mixing the various solid materials. After pre-mixing, unscrew the bolt 29 and pull out the moving plate 27 to remove the control plate 28 from the fixed box 26, exposing the circular hole in the center of the control plate 28. When the feeding speed needs to be controlled, adjust the exposed area of ​​the circular hole; for slow feeding, adjust the area of ​​the hole. This reduces the exposed area of ​​the circular hole, and the moving plate 27 is pulled outwards over a short distance. Conversely, the premixed material flows down from the circular hole through the feed hopper 7 into the conveying chamber 15, where it is conveyed at a uniform speed by two conveying rollers 2 and sheared. The sheared material flows down from the discharge port 3 into the mixing chamber 21, where it is stirred and melted with the liquid material. The third motor 16 is started to drive the stirring rod 20 to rotate the stirring blade 22 to stir the material. The brush 8 connected to the spring 13 in the stirring blade 22 adheres to the inner wall and cleans the material adhering to the inner wall of the mixing chamber 21 during the stirring process. At the same time, the brushed material is allowed to re-participate in the mixing. After preparation, the clamp 24 on the discharge port 25 is opened to release the material from the discharge port 25.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
