Description

Technical Field

[0001] This utility model relates to the field of cable pipe processing technology, specifically to an anti-deformation MPP cable pipe extrusion device. Background Technology

[0002] Deformation-resistant MPP cable conduit, also known as MPP power cable protection conduit, is a type of pipe made primarily of modified polypropylene. This conduit exhibits significant high-temperature resistance and external pressure resistance, making it particularly suitable for the installation of power cables and providing effective protection. MPP cable conduit has a high heat distortion temperature, maintaining its shape stability even at high temperatures, and is not prone to deformation or cracking. This makes it especially suitable for the long-term protection of power cables, as power cables generate heat during operation. MPP cable conduit's excellent external pressure resistance allows it to withstand external pressure from soil, vehicles, and other sources, ensuring the safe installation of power cables. MPP cable conduit also possesses good electrical insulation properties, effectively isolating power cables from the external environment and improving cable safety. Furthermore, MPP cable conduit is lightweight and has a smooth surface, facilitating construction and installation while reducing frictional resistance during cable laying.

[0003] In the manufacturing process of deformation-resistant MPP cable conduits, plastic is first poured into a plasticizer for plasticization, and then extruded into cable conduits using blow molding equipment. However, during the feeding process of the plastic into the plasticizer, bridging problems easily occur due to the unevenness of the plastic, causing blockages in the feeding process and reducing the efficiency of the cable conduit extruder's feeding structure. Therefore, a deformation-resistant MPP cable conduit extrusion device is proposed to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-deformation MPP cable pipe extrusion device with advantages such as anti-clogging. It solves the problem that bridging can easily occur during the feeding process due to uneven plastic material, leading to blockage and reduced efficiency of the cable pipe extruder's feeding structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-deformation MPP cable pipe extrusion device, including a support, an extruder body fixedly installed on the top of the support, a hopper fixedly installed above the extruder body, and a stirring mechanism provided on the inner side of the hopper;

[0006] The stirring mechanism includes a mounting plate, a first motor is fixedly mounted on the top of the mounting plate, a shaft is fixedly mounted on the output shaft of the first motor, blades are fixedly mounted on the outer wall of the shaft, a top material rod is provided on the lower side of the shaft, and a lifting mechanism is provided on the outer side of the mounting plate.

[0011] Furthermore, the fixing box has a strip-shaped opening on the side near the connecting block, and the connecting block passes through the inside of the strip-shaped opening.

[0015] 1. This deformation-resistant MPP cable pipe extrusion device, by starting the first motor, can drive the shaft to rotate, which in turn drives the blades to rotate. The blades are used to stir the raw materials inside the hopper. When the shaft rotates, it can drive the connecting plate to rotate synchronously, and drive the two top rods to rotate.

The up and down movement of the top rods can clear the raw materials inside the hopper, which can achieve a good anti-clogging effect.

[0016] 2. This deformation-resistant MPP cable pipe extrusion device can drive the lead screw to rotate by starting the second motor, which in turn drives the threaded sleeve to move up and down, and at the same time drives the connecting block to move up and down, thereby driving the mounting plate to move up and down. This makes it easy to adjust the height of the blades and adjust the mixing range, thus improving the mixing efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 3 The deformation-resistant MPP cable pipe extrusion device in this embodiment includes a bracket 1, an extruder body 2 fixedly installed on the top of the bracket 1, and a hopper 3 fixedly installed above the extruder body 2.

[0023] In this embodiment, a stirring mechanism is provided inside the hopper 3. The stirring mechanism includes a mounting plate 4, which is located on the upper side of the hopper 3. A first motor 5 is fixedly mounted on the top of the mounting plate 4. A shaft 6 is fixedly mounted on the output shaft of the first motor 5. The shaft 6 extends into the interior of the hopper 3. Two blades 7 are fixedly mounted on the outer wall of the shaft 6. The two blades 7 are located on the left and right sides of the shaft 6, respectively. A top feed rod 9 is provided on the lower side of the shaft 6. By starting the first motor 5, the shaft 6 can be driven to rotate, which in turn drives the blades 7 to rotate. The blades 7 are used to stir the raw materials inside the hopper 3 to ensure that their composition is uniform.

[0024] The bottom of the shaft 6 is fixedly connected to the connecting plate 8, and the top material rod 9 is fixedly installed at the bottom of the connecting plate 8. There are two top material rods 9. When the shaft 6 rotates, it can drive the connecting plate 8 to rotate synchronously and drive the two top material rods 9 to rotate, which facilitates the unblocking of the raw material at the bottom of the hopper 3.

[0025] In this embodiment, a lifting mechanism is provided on the outer side of the mounting plate 4. The lifting mechanism includes a fixed box 10, which is fixedly installed on the top of the extruder body 2. A second motor 11 is fixedly installed inside the fixed box 10. A lead screw 12 is fixedly installed on the output shaft of the second motor 11. A bearing is fixedly installed inside the fixed box 10. The upper end of the lead screw 12 is tightly fitted with the inner ring of the bearing. A threaded sleeve 13 is threadedly connected to the outer side of the lead screw 12. A connecting block 14 is fixedly connected to the outer side of the threaded sleeve 13. The side of the connecting block 14 away from the threaded sleeve 13 is fixedly connected to the mounting plate 4. By starting the second motor 11, the lead screw 12 can be rotated, and the threaded sleeve 13 can be moved up and down. At the same time, the connecting block 14 can be moved up and down, thereby moving the mounting plate 4 up and down, which facilitates the adjustment of the height of the top rod 9 and the blade 7.

[0026] The fixing box 10 has a slot 15 on the side near the connecting block 14, and the connecting block 14 passes through the inside of the slot 15. The slot 15 facilitates the movement of the connecting block 14. Meanwhile, a slider 16 is fixedly connected to the side of the threaded sleeve 13 away from the connecting block 14. A guide rail 17 is fixedly installed inside the fixing box 10, and the slider 16 is slidably connected to the inside of the guide rail 17. The cooperation between the slider 16 and the guide rail 17 can guide the threaded sleeve 13, thereby improving the stability of the structure.

[0027] The working principle of the above embodiments is as follows:

[0028] In use, the first motor 5 drives the shaft 6 to rotate, which in turn drives the blades 7 to rotate. The blades 7 stir the raw materials inside the hopper 3. When the shaft 6 rotates, it drives the connecting piece 8 to rotate synchronously, which in turn drives the two top rods 9 to rotate. At the same time, the second motor 11 drives the lead screw 12 to rotate, which in turn drives the threaded sleeve 13 to move up and down, and at the same time drives the connecting block 14 to move up and down, thereby driving the mounting plate 4 to move up and down. This facilitates the adjustment of the height of the top rods 9 and the blades 7. The up and down movement of the top rods 9 clears the raw materials inside the hopper 3, achieving a good anti-clogging effect.
