Description

Technical Field

[0001] This utility model belongs to the technical field of mixing devices, specifically relating to a mixing device for producing cable sheathing materials. Background Technology

[0002] Cable sheathing material is used to wrap the cable core. It plays a key role in protecting the internal structure of the cable, achieving insulation, waterproofing, moisture protection, and corrosion protection.

[0003] The production process of cable sheathing materials mainly includes raw material preparation, mixing, extrusion, cooling and shaping, traction, and winding. Based on the performance requirements of the cable sheathing material, suitable base resins must be selected, such as polyvinyl chloride (PVC), polyethylene (PE), cross-linked polyethylene (XLPE), and ethylene propylene rubber (EPR). Different resins possess unique characteristics; for example, PVC has good insulation and mechanical properties, while PE exhibits excellent water resistance and low-temperature resistance. Next, the tested base resin and various additives are added to a high-speed mixer according to a specific formula ratio. The high-speed mixer, with its high-speed rotating agitator, enables the materials to be uniformly mixed in a short time and also preheats the materials during the mixing process, thus preparing them for subsequent extrusion processing.

[0004] However, some problems still exist in the current mixing device during use. For example, the housing is directly connected to the discharge pipe. When the mixing device completes the mixing of raw materials, if the discharge pipe is opened directly to discharge the materials, all the raw materials will flow directly into the discharge pipe. However, the opening of the discharge pipe is smaller than the internal size of the housing. This will cause the raw materials to flow directly into the discharge pipe and thus cause blockage. Utility Model Content

[0005] The purpose of this utility model is to provide a mixing device for the production of cable sheathing materials, which aims to solve the problem in the prior art where the existing box is directly connected to the discharge pipe. When the mixing device completes the mixing of raw materials, if the discharge pipe is opened directly for discharge, all the raw materials will flow directly into the discharge pipe. However, the opening of the discharge pipe is smaller than the internal size of the box, which will cause the raw materials to flow directly into the discharge pipe and thus cause blockage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for producing cable sheathing materials, comprising a box body, a feeding hopper connected to the top of the box body, a discharge pipe connected to the bottom of the box body, a stirrer assembled inside the box body, a supporting filter plate installed inside the box body, a baffle inserted into the end face of the box body, a control box provided on the side wall of the box body, a rectangular block connected to the end face of the box body, a guide rod installed inside the rectangular block, a bidirectional threaded rod installed inside the rectangular block, a threaded sleeve threadedly connected to the surface of the bidirectional threaded rod, and a fixing block connected to the top of the threaded sleeve.

[0007] As a preferred embodiment of the mixing device for producing cable sheathing material according to this utility model, the bidirectional threaded rod can be rotatably connected to the rectangular block through a bearing.

[0008] In a preferred embodiment of the mixing device for producing cable sheathing material according to this utility model, the threaded sleeve is fitted onto the surface of the guide rod, and the threaded sleeve can be slidably connected to the rectangular block through the guide rod.

[0009] As a preferred embodiment of the mixing device for producing cable sheathing material according to this utility model, the fixed block can form a reciprocating threaded motion with the rectangular block through a threaded sleeve, a guide rod, and a bidirectional threaded rod.

[0010] As a preferred embodiment of the mixing device for producing cable sheathing material according to this utility model, an installation block is installed on the side wall of the box, a threaded rod is rotatably connected inside the installation block, a mating block is threadedly connected to the surface of the threaded rod, the mating block is connected to the side wall of the control box, and the internal opening size of the mating block is adapted to the installation block.

[0011] As a preferred embodiment of the mixing device for producing cable sheathing material according to this utility model, the mounting block is internally rotatably connected to a worm gear, and the surface of the threaded rod is fixedly connected to a worm wheel.

[0012] In a preferred embodiment of the mixing device for producing cable sheathing material according to this utility model, the threaded rod can be rotatably connected to the mounting block via a worm gear and a worm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By coordinating the threaded sleeve, guide rod, and bidirectional threaded rod, the fixing block's effect on the rectangular block can be released, facilitating the removal of the baffle and exposing the mesh openings of the filter plate. In this way, after the cable sheath material is mixed, opening the discharge pipe allows the material to be evenly fed through the mesh openings of the filter plate under the combined action of the agitator and the filter plate, effectively preventing the potential blockage caused by all the cable sheath material rushing into the discharge pipe when it is opened directly.

[0015] The worm gear and worm shaft work together to drive the threaded rod to rotate inside the mounting block. Then, the mating block moves linearly along the threads on the surface of the threaded rod, thereby raising and lowering the control box. This allows operators to flexibly adjust the height of the control box according to their needs, greatly improving ease of operation and meeting the needs of operators of different heights, effectively increasing work efficiency and operational comfort.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figures 1-4The present invention provides the following technical solution: a mixing device for producing cable sheath material, comprising a box 1, a feeding hopper 2 connected to the top of the box 1, a discharge pipe 3 connected to the bottom of the box 1, a stirrer 4 installed inside the box 1, a supporting filter plate 5 installed inside the box 1, a baffle 6 inserted into the end face of the box 1, a control box 17 provided on the side wall of the box 1, a rectangular block 7 connected to the end face of the box 1, a guide rod 8 installed inside the rectangular block 7, a bidirectional threaded rod 9 installed inside the rectangular block 7, a threaded sleeve 16 threadedly connected to the surface of the bidirectional threaded rod 9, and a fixing block 10 connected to the top of the threaded sleeve 16.

[0024] The agitator 4 consists of a stirring motor and a stirring rod. The stirring motor is electrically connected to the control box 17. After the control box 17 is started, the output shaft drives the stirring rod to rotate, thereby stirring the cable sheath material fed from the feed hopper 2. After stirring and molding, the raw material is discharged to facilitate subsequent production of cable sheath material. The support filter plate 5 is made of stainless steel, which makes it impact-resistant and prevents the cable sheath material from falling and deforming the support filter plate. The box body 1 is made of metal, and its bottom is equipped with support legs to facilitate material discharge through the discharge pipe 3. A control valve is installed on the discharge pipe 3 to facilitate the opening of the discharge pipe 3 for material discharge.

[0025] Preferably, the bidirectional threaded rod 9 can be rotatably connected to the rectangular block 7 via a bearing.

[0026] In practical use, the operator can rotate the bidirectional threaded rod 9 to allow it to rotate stably along the inner ring of the bearing inside the rectangular block 7, thus ensuring the stability of the rotation of the bidirectional threaded rod 9.

[0027] Preferably, the threaded sleeve 16 is fitted onto the surface of the guide rod 8, and the threaded sleeve 16 can form a sliding connection with the rectangular block 7 through the guide rod 8.

[0028] In practical use, when the operator rotates the bidirectional threaded rod 9, the threaded sleeve 16 moves along the threads on the surface of the bidirectional threaded rod 9. At the same time, the threaded sleeve 16 also slides along the surface of the guide rod 8. The guide rod 8 serves to limit the position of the threaded sleeve 16, effectively preventing the threaded sleeve 16 from rotating with the bidirectional threaded rod 9.

[0029] Preferably, the fixed block 10 can form a reciprocating threaded motion with the rectangular block 7 through the threaded sleeve 16, the guide rod 8 and the bidirectional threaded rod 9.

[0030] In practical use, when the operator rotates the bidirectional threaded rod 9, the threaded sleeve 16 moves along the threads on the surface of the bidirectional threaded rod 9. Subsequently, the threaded sleeve 16 pulls the fixing block 10 to move together, and the fixing block 10 moves at the top of the rectangular block 7. The movement of the rectangular block 7 can achieve the removal or blocking of the front end of the baffle 6. This design greatly facilitates the fixing and disassembly of the baffle 6.

[0031] Preferably, a mounting block 11 is installed on the side wall of the housing 1, and a threaded rod 12 is rotatably connected inside the mounting block 11. A mating block 13 is threadedly connected to the surface of the threaded rod 12. The mating block 13 is connected to the side wall of the control box 17, and the size of the mating block 13 is adapted to the internal opening of the mounting block 11.

[0032] In practical use, when the threaded rod 12 rotates, the mating block 13 moves along the threads on the surface of the threaded rod 12. Since the internal opening size of the mating block 13 matches that of the mounting block 11, this effectively prevents the mating block 13 from rotating with the threaded rod 12. Therefore, when the mating block 13 moves along the threads on the surface of the threaded rod 12, because it is connected to the side wall of the control box 17, the mating block 13 will drive the control box 17 to move together.

[0033] Preferably, the mounting block 11 is internally rotatably connected to a worm gear 15, and the surface of the threaded rod 12 is fixedly connected to a worm wheel 14.

[0034] In practical use, the operator rotates the worm gear 15 to make it move inside the mounting block 11. The worm gear 15 will drive the worm wheel 14 to rotate. The worm wheel 14 is fixedly connected to the threaded rod 12, so the worm wheel 14 will drive the threaded rod 12 to rotate together. This design makes it easy for the threaded rod 12 to rotate inside the mounting block 11.

[0035] Preferably, the threaded rod 12 can be rotatably connected to the mounting block 11 via the worm gear 14 and the worm 15.

[0036] In practical use, the operator rotates the worm gear 15, which drives the worm wheel 14 to move, and the worm wheel 14 in turn drives the threaded rod 12 to rotate. As the threaded rod 12 rotates, the mating block 13 moves along the threads on its surface. When the mating block 13 moves along the threads of the threaded rod 12, since the mating block 13 is connected to the control box 17, it will also drive the control box 17 to move together. This design makes the adjustment of the control box 17 more convenient.

[0037] Working Principle: After the cable sheathing material is fed into the feed hopper 2, it falls onto the support filter plate 5. At this time, the operator starts the agitator 4 through the control box 17, and the agitator 4 immediately begins to work, mixing the cable sheathing material in the box 1. After mixing is completed, the operator manipulates the bidirectional threaded rod 9 to rotate. During this process, the threaded sleeve 16 moves along the threads on the surface of the bidirectional threaded rod 9 and slides along the surface of the guide rod 8. Subsequently, the threaded sleeve 16 pulls the fixing block 10 to move together, and the fixing block 10 slides on the top of the rectangular block 7. The movement of the rectangular block 7 can remove the front end of the baffle 6, thereby releasing the fixation of the baffle 6. Afterwards, the operator pulls out the baffle 6, exposing the mesh opening of the support filter plate 5. At this time, the agitator 4 continues to rotate, working in conjunction with the support filter plate 5, so that the cable sheathing material can be evenly discharged through the mesh opening of the support filter plate 5. This design effectively avoids the blockage problem that may be caused by all the cable sheathing material rushing into the discharge pipe 3 when the discharge pipe 3 is opened directly. Afterwards, the operator opens the discharge pipe 3 to discharge the material. Additionally, the operator rotates the worm gear 15, which drives the worm wheel 14, which in turn rotates the threaded rod 12. As the threaded rod 12 rotates, the mating block 13 moves linearly along the threads on the surface of the threaded rod 12, thereby driving the control box 17 to achieve a lifting function. In this way, the operator can flexibly adjust the height of the control box 17 according to actual needs, greatly improving the convenience of operation, meeting the needs of operators of different heights, and effectively improving work efficiency and operational comfort.
