Description

Technical Field

[0001] This utility model relates to the field of cable preparation technology, and specifically to a mixing device for preparing cable materials. Background Technology

[0002] The rapid development of materials science has provided a rich "raw material library" for cable material blending. New polymer materials, nanomaterials, and high-performance fibers are constantly emerging, offering more choices for blending. Due to their size effect and unique properties, nanomaterials can significantly improve the overall performance of cable materials even with small amounts. For example, adding nano-alumina to cable insulation materials can greatly improve the material's corona resistance and enhance the cable's stability under high-voltage environments.

[0003] Used for long-distance, high-capacity power transmission, cables must withstand high voltage and high current, requiring extremely high insulation performance and mechanical strength. The blending technology combines high-insulation polyolefin materials with additives that enhance anti-aging and anti-electrical treeing properties, ensuring long-term stable operation of the cable in harsh environments and reducing transmission losses and failure rates.

[0004] Utility model application CN202420391693.0 discloses a mixing device for processing insulating cable materials. The device includes a support frame, a mixing tank mounted on the support frame, an opening at the top of the mixing tank covered with a lid, an auxiliary material inlet on the lid, and an auxiliary material cover. A mixing shaft is installed inside the mixing tank, and a motor for driving the mixing shaft is mounted on the support frame. The mixing shaft has forward and reverse stirring spiral blades. A discharge port is located at the bottom of the mixing tank and is covered with a sealing cap. This utility model's mixing device for processing insulating cable materials allows for the main material to be fed through the larger opening of the tank after the lid is opened, while small amounts of auxiliary material are fed through the auxiliary material inlet during the mixing process. The auxiliary material feeding process does not require machine shutdown, and there is no material overflow during mixing. This effectively improves the mixing efficiency of insulating cable materials and ensures the mixing effect of the insulating cable materials.

[0005] The aforementioned patent allows for small-volume input through the auxiliary material inlet, increasing the mixing speed of the raw materials. However, during the mixing process, polyethylene tends to adhere to the barrel wall when mixed with rubber, making it difficult to clean the barrel wall after mixing and preventing the mixing cylinder from being scraped.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of this invention is to provide a mixing device for preparing cable materials that can effectively solve the above-mentioned technical problems.

[0008] To achieve the purpose of this utility model, the following technical solution is adopted:

[0024] like Figures 1 to 5 As shown, a mixing device for preparing cable materials includes: a frame 1, a mixing component 3, and a discharging component 4.

[0025] The mixing assembly 3 comprises a rotating shaft 31, a driven plate 32, a stirring roller 33, an edge scraper 34, a cylinder 35, a first spiral slicer 36, a base plate 37, and a second spiral slicer 38. A drive motor 2 is located beside the rotating shaft 31, and the drive motor 2 is connected to the rotating shaft 31 via a belt drive. The rotating shaft 31 is fixedly connected to the driven plate 32. The stirring roller 33 is rotatably connected to the driven plate 32. The edge scraper 34 is rotatably connected to the driven plate 32, and a torsion spring is provided at the connection between the edge scraper 34 and the driven plate 32. The cylinder 35 is fixedly connected to the rotating shaft 31 and also fixedly connected to the base plate 37. The first spiral slicer 36 is fixedly connected to the rotating shaft 31. The second spiral slice 38 is fixedly connected to the rotating shaft 31. By starting the drive motor 2, the motor drives the rotating shaft 31 to rotate via a belt. The rotating shaft 31 drives the driven plate 32, the first spiral slice 36, and the second spiral slice 38 to rotate synchronously. The driven plate 32 drives the stirring roller 33 to revolve around the rotating shaft 31 and rotate on its own axis to stir the raw materials. At the same time, the scraper 34 rotates close to the inner wall of the cylinder 35 to clean the adhering raw materials. The first spiral slice 36 and the second spiral slice 38 push the raw materials to flow axially and radially, promoting full mixing of the raw materials. At the same time, the second spiral slice 38 lifts the cable-mixed raw materials at the bottom of the mixing cylinder, allowing the mixed raw materials to come into contact with air, increasing the dryness of the raw materials, and facilitating subsequent discharge processing.

[0026] As a supplement, the torsion spring provides a continuous elastic force to the scraper 34, ensuring it remains firmly against the inner wall of the cylinder 35. When the driven plate 32 drives the scraper 34 to rotate around the shaft 31, the scraper 34 can scrape off the raw material adhering to the inner wall of the cylinder 35. During the cable raw material mixing process, some highly viscous materials may adhere to the inner wall of the cylinder 35, affecting the mixing uniformity and equipment operating efficiency. The scraper 34 can promptly clean these adhered materials, allowing them to return to the mixing area and participate in the mixing, while keeping the inner wall of the cylinder 35 clean.

[0027] Meanwhile, the cylinder 35 has rectangular holes on its side, and the bottom plate 37 also has rectangular holes. The area of ​​the holes on the side of the cylinder 35 is larger than the area of ​​the holes in the bottom plate 37. The bottom plate 37 has a dual function. On the one hand, the smaller holes in the bottom plate 37 allow the flow rate of the mixed raw materials to be relatively stable during discharge, avoiding uncontrolled spillage due to excessive discharge, and facilitating subsequent collection and processing of the discharged materials. On the other hand, during the mixing process, the smaller holes in the bottom plate 37 prevent the raw materials from accidentally leaking out from the bottom under the action of stirring and pushing, ensuring that the mixing process is carried out in an orderly manner in a closed space, and ensuring the uniformity and continuity of the mixing. The large area of ​​the holes on the side of the cylinder 35 allows for rapid filling of raw materials during feeding, while the small area of ​​the holes in the bottom plate 37 allows for precise control of the flow rate during discharge. The two work together to realize the feeding of the mixing component 3.

[0028] The discharge assembly 4 includes a discharge bucket 41, a storage bin 42, and a material blocker 43. The discharge bucket 41 is fixedly connected to the storage bin 42. The material blocker 43 consists of a fixing ring 431, a discharge pipe 432, and a material blocking plate 433. The fixing ring 431 is fixedly connected to the discharge pipe 432, and the discharge pipe 432 is rotatably connected to the material blocking plate 433. During the mixing process, the material blocking plate 433 is in a closed state, that is, the material blocking plate 433 is tightly attached to the inner wall of the discharge pipe 432, preventing the raw material from flowing out of the storage bin 42 through the discharge pipe 432. At this time, the mixed cable raw material is continuously stored in the storage bin 42, which has a certain capacity to meet the mixing production needs of different scales. The material blocking plate 433 is rotated around the connection point with the discharge pipe 432 by manual driving. As the baffle plate 433 rotates, a gap gradually forms between the baffle plate 433 and the inner wall of the discharge pipe 432. Under the action of gravity, the raw material in the storage box 42 begins to enter the discharge pipe 432 through the gap and flows along the discharge pipe 432 to the storage bucket, discharging the mixed cable raw material.

[0029] Working principle:

[0030] By starting the drive motor 2, the motor drives the rotating shaft 31 to rotate via the belt. The rotating shaft 31 drives the driven plate 32, the first spiral slice 36, and the second spiral slice 38 to rotate synchronously. The driven plate 32 drives the stirring roller 33 to revolve around the rotating shaft 31 and rotate on its own axis to stir the raw materials. At the same time, the scraper 34 rotates close to the inner wall of the cylinder 35 to clean the adhering raw materials. The first spiral slice 36 and the second spiral slice 38 push the raw materials to flow axially and radially, promoting thorough mixing of the raw materials. At the same time, the second spiral slice 38 lifts the cable-mixed raw materials at the bottom of the mixing cylinder, allowing the mixed raw materials to come into contact with air, increasing the dryness of the raw materials, and facilitating subsequent discharge processing. During the mixing process, the baffle plate 433 is in a closed state, that is, the baffle plate 433 is tightly attached to the inner wall of the discharge pipe 432, blocking the raw materials from flowing out of the storage box 42 through the discharge pipe 432. At this time, the mixed cable raw materials are continuously stored in the storage box 42. The storage box 42 has a certain capacity to meet the needs of different scales of mixing production. The material blocking plate 433 is manually driven to rotate around the connection point with the discharge pipe 432. As the material blocking plate 433 rotates, a gap is gradually formed between the material blocking plate 433 and the inner wall of the discharge pipe 432. Under the action of gravity, the raw materials in the storage box 42 begin to enter the discharge pipe 432 through the gap and flow along the discharge pipe 432 to the storage bucket, thus discharging the mixed cable raw materials.
