[0054] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0055] Embodiment 1:

[0056] As Figures 1 to 6 shown, the present invention provides a cable extrusion device, including: an extruder 1 for melting and extruding plastic and rubber materials, an extrusion die 2 arranged on the extruder 1 for guiding the cable core to pass through and wrapping the materials extruded by the extruder 1 on the cable core, and a base 3 arranged on one side of the extruder 1 for support.

[0057] In order to prevent the plastic material wrapped around the cable core from deforming due to the influence of high temperature after being wrapped in the extrusion die 2, resulting in non-roundness, a rolling structure for rolling the rubber material wrapped around the cable core is arranged on the base 3. The rolling structure includes a rolling structure for extruding the material on the cable core, a driving structure for controlling the circular motion of the rolling structure, and an adjusting structure for adjusting the angle of the rolling structure.

[0058] Among them, the rolling structure includes a support frame 4 arranged above the base 3, a connecting turntable 401 on one side of the support frame 4, an annular shaft 402 arranged on one side of the connecting turntable 401 to provide a rotation fulcrum for the connecting turntable 401. The annular shaft 402 is rotatably installed on the support frame 4, an extrusion roller 403 on one side of the connecting turntable 401, a roller frame 404 rotatably installed on the extrusion roller 403 to support the extrusion roller 403, an adjusting disk 405 rotatably installed on one side of the roller frame 404, a guiding component arranged on the adjusting disk 405 to limit the moving direction of the adjusting disk 405. A through hole corresponding to the discharge port of the extrusion die 2 and for the cable core wrapped with material to pass through is opened on the connecting turntable 401. The cable core after being coated with plastic will move towards the connecting turntable 401 through the extrusion die 2, and at the same time, the material coated on the surface of the core will contact the extrusion roller 403.

[0059] Among them, the guiding component includes a guiding rod 406 arranged on one side of the adjusting disk 405 to limit the moving direction of the adjusting disk 405 and a limiting plate 407 arranged on one side of the connecting turntable 401. The guiding rod 406 is slidably installed on the limiting plate 407. The cooperation of the guiding rod 406 and the limiting plate 407 can prevent the position of the adjusting disk 405 from shifting.

[0060] Among them, the driving structure includes a linkage gear ring 5 arranged on the annular shaft 402, a linkage gear 501 below the linkage gear ring 5. The linkage gear 501 meshes with the linkage gear ring 5, a motor 502 with an output end arranged on the linkage gear 501 to drive the linkage gear 501 to rotate, and a bracket 503 arranged on one side of the support frame 4 to support the motor 502. The bracket 503 is arranged on the bottom side of the motor 502. When the motor 502 is started, it can drive the extrusion roller 403 to roll around the surface of the core, so that the extrusion roller 403 can more evenly compact the material coated on the cable core.

[0061] Among them, the adjusting structure includes a threaded seat 6 arranged on one side of the roller frame 404, a threaded insertion rod 601 threadedly installed on the inner wall of the threaded seat 6, and threaded insertion holes 602 opened on the adjusting disk 405. There are multiple threaded insertion holes 602. One end of the threaded insertion rod 601 is threadedly installed in a corresponding threaded insertion hole 602. By rotating the threaded insertion rod 601 and screwing it out of the threaded insertion hole 602, the angular restriction on the roller frame 404 can be released. At this time, the rolling angle of the pressing roller 403 can be adjusted.

[0062] Embodiment 2:

[0063] On the basis of Embodiment 1, in order to enable the pressing roller 403 to adapt to cable cores of different sizes, a linkage structure for adjusting the extrusion space of the rolling structure is arranged on the rolling structure.

[0064] Among them, the linkage structure includes a limit slider 7 slidably installed on the connecting turntable 401, a linkage frame 701 arranged on one side of the limit slider 7 and installed on the guide rod 406, a guide sliding hole 702 opened on the connecting turntable 401 for restricting the sliding direction of the limit slider 7, the limit slider 7 is slidably installed in the guide sliding hole 702, a connecting rod 703 rotatably installed on one side of the limit slider 7, and a rotating ring 704 rotatably installed on the connecting rod 703. The rotating ring 704 is rotatably sleeved on the connecting turntable 401 and is used to drive the connecting rod 703 to move. Rotating the rotating ring 704 can drive multiple pressing rollers 403 to move simultaneously, so that the rolling position of the pressing roller 403 can be adjusted according to the size of the cable core.

[0065] Among them, the linkage structure further includes a limiting component. The limiting component is arranged on one side of the connecting turntable 401. The limiting component includes an adjusting seat 705 arranged on one side of the connecting turntable 401. A limiting screw rod 706 is threadedly installed on the adjusting seat 705. Multiple limiting screw holes 707 are opened on the rotating ring 704. The limiting screw rod 706 is threadedly installed in a corresponding limiting screw hole 707. By rotating the limiting screw rod 706 and screwing it out of the corresponding limiting screw hole 707, the restriction between the rotating ring 704 and the connecting turntable 401 can be released.

[0066] Working principle: During the processing of the cable core, it can pass through the extrusion die 2, and the plastic or rubber is melted by the extruder 1 and coated on the cable core. The cable core coated with plastic will move towards the connecting turntable 401 through the extrusion die 2. At the same time, the cable core will be located between multiple pressing rollers 403. During this process, the motor 502 can be turned on. The output end of the motor 502 can drive the linkage gear 501 to rotate. The rotating linkage gear 501 can drive the annular shaft 402 to rotate on the support frame 4 through meshing with the linkage ring 5, so that the rotating annular shaft 402 drives the connecting turntable 401 to rotate. During the rotation of the connecting turntable 401, it will drive the limiting plate 407 to move in a circular motion, so that the limiting plate 407 moving in a circular motion drives the adjusting disc 405 and the roller frame 404 to move in a circular motion through the guide rod 406, and then the roller frame 404 drives the pressing rollers 403 to roll around the cable core, compacting the plastic material on the core to prevent its deformation. Before processing, by rotating the threaded insertion rod 601 and screwing it out of the threaded insertion hole 602, the angle limit of the roller frame 404 can be released. At this time, the roller frame 404 can be rotated and rotated on the adjusting disc 405 to adjust the rolling angle of the pressing rollers 403. It can also cooperate with adjusting the rotation speed of the output shaft of the motor 502 to adjust according to the discharging speed of the cable core, so that the pressing rollers 403 can compact the material coated on the cable core more evenly. After adjusting the angle of the pressing rollers 403, the threaded insertion rod 601 can be screwed back into the corresponding threaded insertion hole 602 to fix the angle of the pressing rollers 403 again.

[0067] By rotating the limiting screw 706 and screwing it out of the corresponding limiting screw hole 707, the restriction between the rotating ring 704 and the connecting turntable 401 can be released. At this time, the rotating ring 704 can be rotated. When the rotating ring 704 rotates, it will drive one end of multiple connecting rods 703 to rotate and move, so that the other end of the connecting rod 703 rotates and pulls the limiting slider 7 to move on one side of the limiting slider 7. The moving limiting slider 7 will slide in the guiding sliding hole 702, thereby restricting the moving direction of the limiting slider 7 and preventing it from shifting. The continuously moving limiting slider 7 will drive the linkage frame 701 to move, so that the linkage frame 701 drives the guide rod 406 to slide on the limiting plate 407. The sliding guide rod 406 can drive the adjusting disc 405 and the roller frame 404 to move, and then the roller frame 404 drives the pressing rollers 403 to move, so that the rolling position of the pressing rollers 403 can be adjusted according to the size of the cable core.

[0068] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations therein.
