Description

Technical Field

[0001] The invention relates to the technical field of cable processing, and in particular to a cable core coating molding device for cable processing. Background Art

[0002] Cables are usually rope-like cables made of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a center. The entire outer surface is covered with a highly insulating covering layer. The cable has the characteristics of internal power supply and external insulation. When processing the cable, it is often necessary to cover the outer surface of the cable core with an insulating layer, usually a mica tape;

[0003] When the cable is processed for overmolding, a coating machine is required. When the coating machine is coating the cable core, there are pollutants on the surface of the cable core. The pollutants in the cable core may cause the cable insulation layer to age faster and reduce its insulation performance, thereby affecting the safety performance and service life of the cable. At the same time, the mica tape is prone to wrinkles and deformation during coating, affecting the insulation effect, and how to fix the mica tape to the surface of the cable core at the beginning is also a problem. Therefore, we proposed a cable core overmolding equipment for cable processing. Summary of the invention

The cable cores are evenly distributed on both sides of the mica tape, and the twisting assembly drives the cable cores to rotate and twisted with each other. Finally, the mica tape is also wrapped around the surface of the cable core and rolled up with the twisted cable core. At the same time, the mica tape is wrapped around the surface of the cable core. When the cable core rotates, the mica tape is clamped to avoid the fixation of the mica tape and the cable core before coating, reduce cumbersome operations, and make the coating operation more convenient.

After installation, the sliding cylinder cooperates with the sliding rod to limit the reel, thereby avoiding the reel from moving randomly during coating, thereby avoiding the mica tape from moving randomly and avoiding the mica tape from twisting, thereby ensuring the tightness of the coating and improving the coating quality.

[0026] The present invention arranges reels, wherein three staggered reels are arranged, and three mica tapes unwound are inserted into a slot body and partially overlapped to avoid gaps, thereby forming a wider mica tape, thereby increasing the length after one winding and improving the winding efficiency. In addition, multiple mica tapes can also be overlapped with each other to increase the coating thickness and enhance the protection effect on the cable core.

[0027] The present invention provides a cleaning component, and a scraper is used to scrape the surface of the cable core to remove surface pollutants, thereby ensuring that the clean cable core enters the coating tube for coating. Since the scraper is inclined toward the inside of the coating tube and is connected to the inner wall of the tube body, the scraped pollutants will slide to the outside of the tube body under the influence of gravity, thereby avoiding contamination of the coating tube.

[0028] The present invention sets a twisting component to drive the gear ring to rotate, drive a hole plate to rotate, and then drive the remaining hole plates to rotate through the connecting plate, so as to provide rotation for the rotation and covering of the cable core. The conical distribution of the hole plate makes it easier to insert the cable core at the beginning, and can guide multiple cable cores into a cone and gradually approach each other, so as to avoid the cable core from being stretched suddenly when being covered, and to avoid deformation and damage of the cable core. The shell protects the meshing part of the gear ring and the gear, avoids slippage between the gear and the gear ring, and ensures the transmission. BRIEF DESCRIPTION OF THE DRAWINGS
