[0002] In cable manufacturing, shielding is a crucial step in enhancing the cable's anti-interference performance and ensuring signal transmission stability. Before shielding, multiple cable cores must be twisted to form a regular strand structure, ensuring the subsequent shielding layer's fit and uniformity.

The support roller 9-2 is rolled with several rollers 9-3 rotatably mounted on the other side of the annular wall of the winding disk 4.

[0028] The specific operation steps of this invention are as follows: Preliminary preparations Equipment Inspection: Before starting the device, check the connection stability of core components such as cable core unwinding mechanism 2, cable winding mechanism 3, drive mechanism 8, and support rotation mechanism 10, and ensure that key transmission parts such as bearing housing 10-5 and gear meshing are adequately lubricated and free from jamming or abnormal noise; check the coaxiality of straightening guide mechanism 6, clamping mechanism 7 and winding disc 4 to ensure smooth cable transmission path.

[0029] Winding installation and fixing: According to the specifications of the processed cable, install the cable core reel onto the cable core unwinding mechanism 2, and install the insulation shielding material roll onto the roller 17 of the insulation layer winding 11; adjust the circumferential position of the insulation layer winding 11 and the cable winding 12 by bolt fixing assembly 13 (loosen the self-locking nut 13-3, pull out the spline 13-1, move the mounting seat 14 along the outer adjustment groove 4-1 / inner adjustment groove 4-2 so that the spline through groove 14-1 is aligned with the target outer spline hole 4-3 / inner spline hole 4-4, insert the spline 13-1 and tighten the self-locking nut 13-3 to complete the fixing).

[0030] Height adjustment: Start the lifting cylinder 18 to drive the movable roller seat 16 to move up and down along the guide rod 19, adjust the height of the roller 17 to match the requirements of the cable core twist density and the insulation layer covering pitch and covering thickness; adjust the rotation resistance of the roller 17 through the bearing brake to ensure the stable release speed of the cable core and the insulation shielding material.

[0031] Adjusting the position of the inlet and outlet lines: Loosen the positioning bolts of the movable column 20 and the slide rail 21, and adjust the front and rear position of the movable column 20 so that the clamping mechanism 7, the straightening guide mechanism 6 at the outlet end and the winding disc 4 maintain a reasonable distance to meet the requirements of cable processing length; check the elasticity of the spring 7-4 of the clamping mechanism 7 to ensure that the first guide wheel 7-3 can extend and retract flexibly.

[0032] II. Incoming Line and Straightening Process Start the cable core unwinding mechanism 2 (passive unwinding mode) to pull out the cable core synchronously and pass it through the straightening guide mechanism 6 on the centering bracket 5 (the cable core passes through the triangular area formed by the three guide wheels 6-3 and is forcibly straightened under the limiting action of the guide wheels 6-2 to eliminate the original bending deformation and ensure the uniformity of subsequent twisting). The straightened cable core is guided to continue to be fed to the inner ring of the winding disc 4, and is coaxial with the circular structure composed of multiple cable windings 12, in preparation for the twisting operation.

[0033] III. Synchronous Twisting and Shielding Layer Covering Start drive mechanism 8: The geared motor 8-2 runs, and through the drive gear 8-3 meshing with the drive teeth 8-6 of the winding disk 4, it drives the winding disk 4 to rotate; the driven gears 8-5 on both sides of the drive gear 8-3 simultaneously mesh with the drive teeth 8-6 to ensure that the winding disk 4 rotates smoothly without deviation or wobbling. Cable core twisting: As the winding disc 4 rotates, the cable winding 12 revolves synchronously around the cable core axis. The roller 17 is passively rotated under the traction of the cable core, and at the same time, it provides appropriate resistance through the bearing brake, causing multiple cable cores to twist together to form a regular strand structure. The twisting density is adjusted by the speed of the reduction motor 8-2. The faster the speed, the tighter the twisting. Shielding layer coating: Simultaneously with the twisting operation, the insulation layer winding 11 rotates with the winding disc 4, and the insulation shielding material is released at a uniform speed under the rotation of the roller 17, and is evenly wrapped around the surface of the twisted cable core; by adjusting the circumferential position of the insulation layer winding 11 and the height of the roller 17, the coating pitch and coating thickness are controlled to ensure that the shielding layer is tightly attached without wrinkles or gaps. Coordinated support and guidance: The bearing seat 10-5 of the support rotation mechanism 10 provides rotational support for the winding disk 4, and the support rod 10-3 and the support plate 10-4 ensure that the winding disk 4 is subjected to balanced force; the support roller 9-2 of the support guidance mechanism 9 and the roller 9-3 of the winding disk 4 roll in cooperation to share the weight of the winding disk 4, reduce rotational resistance, and ensure operational stability.

[0034] IV. Pressing, Straightening and Winding Compacting process: The twisted and wrapped cable is conveyed to the compacting mechanism 7 at the outlet end. The three No. 1 guide wheels 7-3 are pressed tightly against the cable surface under the elastic force of the springs 7-4, which elastically compacts the shielding layer, eliminates the gap between the wrapping layer and the cable core, and at the same time initially corrects the straightness of the cable. Secondary straightening: After being compressed, the cable passes through the straightening guide mechanism 6 on the movable column 20 and is straightened again by the limit of the three guide wheels 6-3 to ensure that the straightness of the finished cable meets the standard and avoids bending caused by twisting or wrapping. Winding and forming: Start the cable winding mechanism 3 (active winding mode), the winding speed is slightly greater than the cable core unwinding speed and wrapping speed, so that the cable always maintains appropriate tension; during the winding process, the cable winding mechanism 3 rotates at a uniform speed, neatly winding the processed cable onto the winding shaft, completing the entire processing process.

[0035] V. Shutdown and Follow-up Procedures After processing is completed, first turn off the drive mechanism 8. After the winding disc 4 stops rotating, turn off the cable core unwinding mechanism 2 and the cable winding mechanism 3. Loosen the winding shaft fixing part of the cable winding mechanism 3 and remove the finished cable roll.

[0036] Clean and maintain the equipment: remove residual material from the surface of roller 17, check the wear of each gear and bearing, and add grease; loosen the bolt fixing assembly 13, and reset the insulation layer winding 11 and cable winding 12 to prepare for the next processing.

[0037] Compared with the prior art, the beneficial effects of the present invention are: 1. The insulation layer winding 11 and the cable winding 12 are simultaneously and adjustablely mounted on the winding disc 4. Under the drive of the drive mechanism 8, the insulation layer winding 11 and the cable winding 12 are driven to rotate simultaneously, realizing the twisting of the cable core and the covering of the insulation layer. The twisting of the cable core and the covering of the insulation layer are combined into one, saving cable processing time and procedures and improving efficiency. 2. The insulation layer winding 11 and the cable winding 12 adopt an adjustable installation method, which can meet the adjustment requirements of different cable core twisting and covering conditions, and has a wider range of applications; 3. The insulation layer winding 11 and the cable winding 12 are set as a split structure with adjustable height, which can adjust the twist density of the cable core, the insulation layer covering pitch and covering thickness to meet the needs of different twist and covering pitch. 4. The straightening and guiding mechanism 6 can guide and straighten the input of the cable core and the output after the cable is twisted and wrapped, thereby improving the cable yield. 5. The first guide wheel 7-3 in the clamping mechanism 7 can compact the twisted and wrapped cable, which helps to straighten the cable initially and compact and adhere the insulation layer.

[0038] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
