Description

Technical Field

[0001] The invention relates to the technical field of coiling heads, and in particular to a coiling head structure of a wear-resistant cable coiling machine. Background Art

[0002] Cable coiling machines are equipment used to coil cables and are essential in all cable manufacturing companies. In the process of wire production, the produced wires need to be coiled. The wires are usually not coiled on a reel, but are coiled using a coiling head. An opening and closing block is provided on the coiling head. When the wire begins to be coiled, the opening and closing block opens to form a cylindrical shape, providing a temporary coiling core disk for the coiled wire. After the winding is completed, the above-mentioned opened opening and closing block must be retracted and closed, and the diameter becomes thinner, so that the coiled wire can be detached from the coiling head and sent to the next process for film fixing.

[0003] The commonly used looping head controls the opening and closing of the opening and closing block by utilizing the oblique guide chute between the opening and closing block and the looping head looping shaft. When the looping head main shaft descends, it will drive the looping shaft and other components such as the opening and closing block to descend. When the opening and closing block contacts the lower looping disk, the opening and closing block will stop descending. At this time, the looping head that continues to descend will push the opening and closing block to move radially outward through the oblique guide chute, so that the opening and closing block opens and the diameter becomes larger. When the looping head main shaft rises, the opening and closing block will move downward and inward along the oblique guide chute under the action of its own weight, return to a closed state, and the diameter becomes smaller, thereby meeting the needs of wireless coiling of wires. The problem is that in the high-speed production of the above-mentioned mechanism, due to the increase in speed, the frequency of up and down impacts increases, among which the hinge part wears quickly, which greatly affects the movement accuracy, resulting in the opening and closing block not closing smoothly and often getting stuck. After the gap is increased, the abnormal noise increases, which seriously affects the improvement of the wire production efficiency. For this reason, a coiling head structure of a wear-resistant cable coiling machine is proposed to enhance the impact resistance of the structure and improve the service life. Summary of the invention

[0004] The present invention provides a coiling head structure of a wear-resistant cable coiling machine, which solves the problems raised in the above-mentioned background technology and can adapt to the working condition of high-speed coiling, thereby effectively improving the service life of the coiling head.

[0005] The solution of the present invention to solve the above technical problems is as follows: a winding head structure of a wear-resistant cable winding machine, comprising a top flange, an upper connecting block, a tile, a sliding block, a lower connecting block, a bottom flange, a wire pressing disk, a connecting flange, a lower turntable, and a winding head spindle, wherein the top flange is fixedly connected to an upper sleeve, the bottom flange is fixedly connected to a lower sleeve, the lower sleeve is inserted into the upper sleeve, a No. 1 reset spring is installed in the upper sleeve, the No. 1 reset spring is fixedly connected to the lower sleeve, a No. 2 reset spring is sleeved on the outer wall of the upper sleeve, and the two ends of the No. 2 reset spring are respectively connected to the upper connecting block and the lower connecting block The connecting flange, the top flange and the upper connecting block can be connected by bolts, the tile and the sliding block are connected by bolts, three tiles are provided, and two sliding blocks are provided corresponding to each tile installation, the three sliding blocks on the upper side slide relative to the upper connecting block, and the three sliding blocks on the lower side slide relative to the lower connecting block, the bottom flange is connected to the wire pressing disk by bolts, an oil filling hole is provided on the outer wall of the tile, the lower turntable is arranged at the bottom of the wire pressing disk, the winding head main shaft is rotatably connected to the connecting flange, the winding head main shaft is threadedly connected to the limiting nut, and the lower sleeve slides relative to the winding head main shaft.

[0006] Based on the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the tile is fixedly mounted with a connecting piece, which is connected to a sliding block via bolts, and the sliding block can be quickly mounted on the inner side of the tile via bolts.

[0008] Furthermore, the top flange is provided with a bolt hole, and the inner wall of the bolt hole is provided with a spacer, which can protect the contact position between the bolt and the bolt hole, thereby reducing wear during movement.

[0009] Furthermore, the upper connecting block and the lower connecting block are both provided with a limiting sliding block, and the sliding block is provided with a limiting sliding groove corresponding to the limiting sliding block, and the limiting sliding block can be inserted into the limiting sliding groove.

[0010] Furthermore, the limiting slider and the limiting slide groove are both slope structures, so that the limiting slider can drive the tiles to open and close when it is raised or lowered.

[0011] Furthermore, the three tiles can be spliced ​​together to form a cylindrical structure.

[0012] Furthermore, each of the tile outer walls is provided with two oil filling holes corresponding to the sliding block, and the lubricating oil can be input into the tile inner wall through the oil filling holes, thereby lubricating the limiting sliding block and the limiting sliding groove.

[0013] Furthermore, the diameter of the limiting nut is larger than the aperture of the lower sleeve, and a limiting groove is provided at the bottom of the bottom flange corresponding to the limiting nut, so that the winding head spindle can stably slide on the lower sleeve.

[0015] 1. Compared with the existing cable winding machine winding head structure, the present application cancels the hinge structure (thin shaft and small hole matching) inside the existing winding head structure, and replaces it with a connecting block with three-side inclined surfaces and a sliding block to slide together, which can effectively reduce wear;

[0016] 2. The sliding inclined surface for friction is provided with oil filling holes, which is convenient for the staff to refuel regularly, thereby further improving the wear resistance of its structure and extending its service life;

[0017] 3. Such a rolling head structure has a larger sliding contact area. When impacting up and down, the force-bearing surface is enlarged, and the impact force during the descent process can be greatly released through the slider guide with a large angle inclination. Compared with the existing rolling head structure connected by a hinge, it is more wear-resistant and impact-resistant and has a longer service life.

The tile 3 is installed with a sliding block 4. The sliding block 4 is squeezed by the upper connecting block 2 and the lower connecting block 5 to slide outward, so that the three tiles 3 can expand outward and become open. The unfolded 3 can be used as a temporary coiling core disk for the cable to be wound into a coil.

[0041] 2. The rising action of the rolling head: the connecting flange 8 drives the top flange 1 to rise, and the No. 1 return spring 11 and the No. 2 return spring 12 press against the bottom flange 6 and the lower connecting block 5. At this time, the lower connecting block 5 and the upper connecting block 2 can be separated under the elastic action of the No. 1 return spring 11 and the No. 2 return spring 12, so that the sliding blocks 4 on both sides can slide and drive the tiles 3 to shrink and merge. After the tiles 3 shrink into place into a tube, the rolling head rises as a whole and separates from the rolled cable, so as to facilitate the unloading of the cable roll.
