Description

TECHNICAL FIELD

[0002] Low-smoke halogen-free radio frequency coaxial cable is a cable specially designed for high-performance signal transmission, and is widely used in wireless communication, broadcasting, monitoring systems, HFC networks and electronic equipment. Its core advantage is that low-smoke halogen-free materials are used as sheaths, which almost do not produce toxic gases and smoke during combustion in extreme conditions such as fire, significantly improving the safety of personnel evacuation and the protection level of equipment. Such cables usually have good flame retardance, electromagnetic interference resistance and stable electrical performance, and are suitable for places with high safety and signal quality requirements, such as high-rise buildings, subways, hospitals and industrial environments. The conductors are usually made of multiple strands of tinned copper wire, which has good conductivity and flexibility.

[0003] In the cable stranding process, the wire coil material of multiple copper wires needs to be fixed on the shaft of the stranding device, and then the locking nut matched with the shaft is tightened to prevent the wire coil material from falling off the stranding device. When replacing the wire coil material, the locking nut also needs to be disassembled in sequence. The disassembly and assembly of the locking nut is time-consuming and laborious, which affects the efficiency of cable stranding. In addition, the wire roller on the stranding device plays a role in paying out the copper wire. Since the copper wire is in contact with the wire roller and rubs against it, some debris will be generated, which will adhere to the stranded copper wire and affect the quality of the cable. Artificial cleaning is required in the stopped state, which is also time-consuming and laborious. SUMMARY

[0015] The present application has the following advantages:

[0016] 1. In the low-smoke halogen-free RF coaxial cable processing stranding device, the mechanical clamping jaws on the feeding frame can clamp the wire coil to be fed. When the feeding frame is connected with the driving equipment, the wire coil can be conveniently fed. A plurality of hollow insertion rods on the rotating support can insert the wire coil. The wedge-shaped abutting strip can be moved to one side of the tapered abutting block of the limiting seat by the moving rod, so as to limit the position of the moving rod after feeding is completed, so that the first abutting ring and the plurality of first abutting wedge blocks remain in abutting state, the limiting plug of the hollow insertion rod is automatically inserted into the limiting plug groove of the wire coil, the wire coil is prevented from sliding on the hollow insertion rod and falling off, the convenience of wire coil feeding is greatly improved, the copper wires are shaped and compacted by the stranding sleeve, the conductor is more compact, the outer diameter is more uniform, the conductor gap is reduced, the stranding conductor is prevented from loosening, and the stranding quality is improved. As the moving rod continues to move, it causes the wedge-shaped contact strip to move to the side of the second contact ring. When the moving rod resets, it can push the second contact ring to fit against the conical contact block, so as to automatically release the limit on the moving rod and make the limit plug automatically disengage from the limit slot, which facilitates the replacement of the wire roll. The limit plate can abut against the limit seat to prevent the moving rod from shifting position during the copper wire stranding process, further improving the stability of the wire roll during operation. In this application, the wire roll is easy and quick to operate when loading and unloading, with high efficiency, saving time and effort, and improving the efficiency of cable stranding processing.

[0017] 2. In this low-smoke halogen-free radio frequency coaxial cable processing stranding device, the scraper inside the threading box can press against the wire roller, so that the wire roller can be rotated when the metal wire is unloaded, which can easily scrape off the debris on the wire roller in time, and avoid it from adhering to the metal wire and affecting the quality of the cable. The collection box on one side of the feeding rack can move synchronously when the wire roll is fed, and push the L-shaped baffle to move, thereby automatically opening the slag discharge port of the threading box, which can facilitate the discharge of debris into the collection box, thereby reducing the amount of debris in the threading box. Through the cooperation of gear and second rack support, the wire roller can rotate again when the debris is discharged, reducing the cleaning dead corner of the wire roller and improving the debris cleaning effect. The second contact wedge can move upward synchronously with the limiting plate to contact the contact head, causing the second contact rod to move horizontally. On the one hand, it can push the rocker plate to deflect, so that when slag is discharged, the first contact rod drives the scraper to automatically retract to the inner wall of the cable box, automatically scraping off the debris attached to the scraper, so that the impurities are automatically discharged into the collection box, and at the same time improving the use effect of the scraper. On the other hand, the second contact rod pushes the rocker plate to deflect, which can cause one end of the rocker plate to knock against the cable box, so that the debris in the cable box is affected by vibration and falls into the collection box, further improving the slag discharge effect and the cable stranding quality.

[0018] 3. In the stranding device for processing low-smoke halogen-free radio frequency coaxial cables, if the limiting plug is pressed against the inner wall of the wire roll and not inserted into the limiting slot, the angle of the hollow plug rod can be rotated to make the limiting plug automatically insert into the limiting slot, thus limiting the wire roll.

The fifth spring 32 stores force, so that the debris can fall into the collection box 30. At the same time, the second rack bracket 34 connected to the L-shaped baffle 31 moves a certain distance and then meshes with the gear 33, causing the wire guide roller 13 to rotate automatically so that the scraper 14 can scrape off the remaining debris on the wire guide roller 13, thereby reducing the cleaning dead corner and causing the debris to fall into the collection box 30. The cable box 12 is equipped with a protective cover to prevent impurities from adhering to the second rack bracket 34 and gear 33, thereby affecting the operation.
