Description

Technical Field

[0001] The present application relates to the technical field of cable forming devices, and in particular, to a cable core centering and adjusting device. Background Art

[0002] Currently, the cable structure mainly consists of a conductor, a shielding layer, an insulating layer, and a sheath. The insulating layer is used to prevent the current in the conductor from leaking out and isolate the conductor from the outside. The material of the insulating layer is generally plastic because plastic has excellent performance and good processing technology performance, and the process is simple during the production of the cable extruded insulating layer.

[0003] When manufacturing the cable insulating layer, the core needs to be first inserted into the mold. Through the forming extruder, the plastic in the barrel is heated. When it reaches a certain temperature, the plastic changes from a solid state to a plastic object in a molten state. Then, through the pushing or stirring of the screw, the fully plasticized plastic is pushed into the head. The material flow reaching the head passes through the annular gap between the die core and the die sleeve and is extruded from the die sleeve opening, extruded around the core to form a continuous and dense insulating layer, and then through cooling and curing, the cable product is made. When the core is inserted a certain distance, it will be affected by external forces such as the traction force of the motor, gravity, and the wire reel wire release tension, resulting in shaking and eccentricity, making the distance between the core and the insulating layer uneven, the electric field distribution on the surface of the insulating layer uneven, and local overheating easily occurs, affecting its transmission performance. In severe cases, it may even lead to insulation breakdown, greatly reducing the safety.

[0004] In the related art, a cable extruder core centering device with the publication number CN210403364U discloses a centering wheel assembly including a centering wheel, a copper sleeve, a rotating shaft, and a bearing. The centering wheel is in a rotary body shape, and an annular groove with a circular arc cross-section is radially provided on the centering wheel. The annular groove plays a role in centering the core during the cable extrusion process; two waist-shaped through holes are provided on the adjusting plate, and two adjusting bolts are provided below the corresponding positions of the waist-shaped through holes of the adjusting plate, and the adjusting bolts are used to adjust the longitudinal position of the adjusting plate.

[0005] Regarding the above related art, the inventor believes that there are the following defects: In order to ensure the centering of the core, each time this structure is adjusted, it is necessary to first loosen the adjusting bolts, hold the adjusting plate by hand to move and adjust the up and down position of the centering wheel, and then tighten the adjusting bolts after the adjustment to fix the wire supporting wheel. This method has low operation efficiency and poor flexibility. Utility Model Content

[0018] Preferably, a pulley with a locking function is installed on the support base.

[0019] By adopting the above technical solution, the centering adjustment device can be moved to different positions and the pulley can be locked, which is convenient to use and makes the handling more labor-saving.

[0020] Preferably, a first oil inlet passage for lubricating and supplying oil to the first guide rail is provided on the first slider, and a second oil inlet passage for lubricating and supplying oil to the second guide rail is provided on the second guide rail.

[0022] Preferably, a total oil inlet and a main oil passage are provided on the second guide rail. One end of the main oil passage is connected to the total oil inlet, and the other end of the main oil passage is simultaneously connected to the first oil inlet passage and the second oil inlet passage.

A flexible protective layer is sleeved on the surface of the wire supporting wheel 6. The flexible protective layer can adopt a protective film. After the core passes through the wire supporting wheel 6, the core can be effectively protected.

[0035] Referring to Figure 1 , the horizontal adjustment mechanism 1 includes a first guide rail 12 and a first slider 14. The first guide rail 12 is installed on the support base 3 through bolts; a first lead screw 13 is rotatably connected inside the first guide rail 12. One end of the first lead screw 13 passes through the first guide rail 12 and is fixedly connected to a horizontal adjustment knob 11. The diameter of the horizontal adjustment knob 11 is larger than that of the first lead screw 13; one side of the first slider 14 close to the first guide rail 12 is threadedly connected to the first lead screw 13, and the first slider 14 is in sliding fit with the first guide rail 12.

[0036] Referring to Figure 1 , the vertical adjustment mechanism 2 includes a second guide rail 22 and a second slider 24. The second guide rail 22 is installed on the first slider 14 through bolts; a second lead screw 23 is rotatably connected inside the second guide rail 22. One end of the second lead screw 23 passes through the second guide rail 22 and is fixedly connected to a vertical adjustment knob 21. The diameter of the vertical adjustment knob 21 is larger than that of the second lead screw 23; one side of the second slider 24 close to the second guide rail 22 is threadedly connected to the second lead screw 23, and the second slider 24 is in sliding fit with the second guide rail 22. Among them, scale marks for adjusting the distance are engraved on both the horizontal adjustment knob 11 and the vertical adjustment knob 21.

[0037] Referring to Figure 2, an inclined first oil inlet channel 15 is provided inside the first slider 14. The first oil inlet channel 15 is provided with a first oil inlet 151 and a first oil outlet 152. The first oil inlet 151 is located above the first oil outlet 152. The first oil inlet 151 is arranged on the side of the first slider 14 away from the first guide rail 12, and the first oil outlet 152 is arranged at the threaded engagement part of the first slider 14 and the first lead screw 13.

[0038] Refer to Figure 2 , an inclined second oil inlet channel 25 is provided inside the second guide rail 22. The second oil inlet channel 25 is provided with a second oil inlet 251 and a second oil outlet 252. The second oil inlet 251 is located above the second oil outlet 252. The second oil inlet 251 is arranged on the side of the second guide rail 22 close to the first guide rail 12, and the second oil outlet 252 is arranged at the threaded engagement part of the second guide rail 22 and the first lead screw 13. A total oil inlet 27 is provided on the side of the second guide rail 22 away from the support base 3. A vertical main oil passage 26 is provided inside the second guide rail 22. One end of the main oil passage 26 is connected to the total oil inlet 27, and the other end is simultaneously connected to the first oil inlet channel 15 and the second oil inlet channel 25. During operation, only by injecting lubricating oil into the main oil passage 26, the simultaneous lubrication of the first lead screw 13 and the second lead screw 23 can be achieved.

[0039] Refer to Figure 1 , the connecting plate 4 is L-shaped. One side of the connecting plate 4 is installed on the side of the second slider 24 away from the second guide rail 22. The other side of the connecting plate 4 is threadedly connected with an adjusting bolt 5. One end of the adjusting bolt 5 screwed into the connecting plate 4 is rotatably connected to the wire supporting wheel 6 through a bearing. The axis of the wire supporting wheel 6 is parallel to the sliding direction of the first slider 14. When there is a small lateral deviation during the wire core transmission, by screwing in and out the adjusting bolt 5, the position of the wire supporting wheel 6 can be locally fine-tuned, so as to further achieve the lateral adjustment of the wire core position.

[0040] The implementation principle of a cable wire core centering adjustment device according to an embodiment of the present application is as follows:

[0041] The pulley 31 at the bottom of the support base 3 has a locking function, and this centering adjustment device can be moved arbitrarily. When there is a lateral position deviation of the wire core, rotate the lateral adjustment knob 11, and the first lead screw 13 rotates accordingly, so that the first slider 14 threadedly connected with it moves along the axial direction of the first lead screw 13, realizing the lateral sliding of the first slider 14 on the first guide rail 12 and driving the lateral movement of the wire supporting wheel 6 to achieve the lateral displacement adjustment; or the position of the wire supporting wheel 6 can be further locally fine-tuned by rotating the adjusting bolt 5 at the connecting plate 4.

[0042] When there is a longitudinal position deviation in the wire core, rotate the longitudinal adjustment knob 21, and the second lead screw 23 will rotate accordingly, causing the second slider 24 threadedly connected thereto to move along the axial direction of the second lead screw 23, realizing the longitudinal sliding of the second slider 24 on the second guide rail 22, and driving the longitudinal movement of the wire supporting wheel 6 to achieve longitudinal displacement adjustment.

[0043] When the lateral adjustment mechanism 1 and the longitudinal adjustment mechanism 2 get stuck during the adjustment process, inject lubricating oil from the main oil inlet 27. After the lubricating oil passes through the main oil passage 26, it enters from the first oil inlet 151 and the second oil inlet 251 respectively. The lubricating oil flows into the first lead screw 13 through the first oil passage 15 and into the second lead screw 23 through the second oil passage 25, realizing the simultaneous lubrication of the lateral adjustment mechanism 1 and the longitudinal adjustment mechanism 2, making the adjustment smoother.

[0044] The above are all preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
