Description

Technical Field

[0001] The present application relates to the technical field of cable processing, and in particular to a twisting device for processing multi-core twisted wire cables. Background Art

[0002] Multi-core cable refers to a cable with more than one insulated core. Multi-core cable plays an important role in electronic products and electronic systems, and is the key link in connecting the various functions of electronic products.

[0003] Multi-core cable is a cable formed by twisting multiple sub-conductors together in a certain direction and according to certain rules by a twisting device. The twisted cable is much softer than a single core of the same diameter and has better bending performance. In the process of cable twisting, in order to increase the density and strength of the cable and improve the insulation and fire resistance of the cable, talcum powder is often applied to the twisted cable at the end of the twisting device; talcum powder can effectively protect the wires and cable structure inside the cable and prevent the cable from short circuit, leakage and other faults; in addition, cable talcum powder also has good chemical stability and corrosion resistance, and can maintain stable performance under harsh environmental conditions.

[0004] The existing talcum powder coating step is usually implemented by a powdering mechanism, which includes a powder box filled with talcum powder. The wire that needs to be powdered is directly inserted from one end of the powder box through the traction of the extruder, and then passed out from the other end, so that a layer of talcum powder is attached to the surface of the wire. However, since talcum powder has certain adhesion and solid plasticity, when the insulated wire core passes through the talcum powder, a cavity brought out by the insulated wire core will be formed in the talcum powder, and part of the cavity will collapse under the action of gravity, so that the subsequent wire core can still be coated with talcum powder. However, it is found in the actual production process that if the humidity in the powder box is high, the talcum powder will be damp and agglomerated, causing the cavity brought out by the insulated wire core to be unable to collapse, thereby affecting the coating effect on the subsequent wire core. Summary of the invention

[0005] In order to overcome the technical problems described in the above-mentioned prior art, the present application provides a twisting device for processing multi-core twisted wire cables.

[0019] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0020] The present application embodiment discloses a twisting device for processing a multi-core twisted wire cable. Figure 1 , Figure 2 and Figure 3 A twisting device for processing multi-core stranded cables includes a stranding machine 1 and a frame 2 arranged at one side of the outlet end of the stranding machine 1, and a powder box 3, a driving component 5 and a powder spraying mechanism are arranged on the frame 2; wherein the powder box 3 is arranged in a cylindrical shape, and both ends thereof are provided with through holes 4 for cables to pass through, so that the cables twisted from the stranding machine 1 can pass through the powder box 3 along the length direction of the powder box 3. The powder box 3 is horizontally rotated and mounted on the frame 2, and talcum powder is contained inside it. The driving component 5 drives the powder box 3 to rotate smoothly on the frame 2, so that the talcum powder in the powder box 3 is driven and poured on the outer periphery of the cable.

[0021] In order to allow the talcum powder to be driven and sprinkled by the rotating powder box 3, refer to Figure 1 , Figure 2 and Figure 3 The inner wall of the powder box 3 is provided with a baffle 8 for driving the talcum powder to move with the powder box 3. Two groups of baffles 8 are provided, and the two groups of baffles 8 are respectively located at the two ends of the powder box 3, and each group of baffles 8 is provided with a plurality of baffles 8, and the plurality of baffles 8 are circumferentially arranged along the inner wall of the powder box 3. When the driving component 5 drives the powder box 3 to rotate, the talcum powder at the bottom of the powder box 3 is lifted to a certain height driven by the baffles 8. As the powder box 3 continues to rotate, the talcum powder carried by the baffles 8 is poured downward under the action of gravity, and the talcum powder in the falling process is poured to the periphery of the cable.

[0022] Considering the effect on cable coating, refer to Figure 2 The straight line where the baffle bar 8 is located is arranged in an eccentric manner with the straight line where the rotation axis of the powder box 3 is located, so that when the powder box 3 rotates, the talcum powder in the powder box 3 is lifted by the baffle bar 8 and slides toward the middle of the powder box 3, ensuring that enough talcum powder is concentrated and poured. At the same time, the surface of the baffle bar 8 is provided with an anti-sticking layer, which is specifically set as a Teflon coating, to reduce the adhesion of talcum powder on the surface of the baffle bar 8, thereby ensuring that the baffle bar 8 can smoothly drive the talcum powder to be poured.

[0023] Regarding the configuration of the drive assembly 5, in the embodiment of the present application, refer to Figure 1 and Figure 2 The driving assembly 5 is configured as a pulley transmission assembly. Specifically, a driven wheel is fixedly sleeved on the powder box 3, a motor is mounted on the frame 2, a driving wheel is fixedly connected to the motor shaft, and the driving wheel and the driven wheel are synchronously driven by a belt. In other embodiments, the driving assembly 5 may be a gear transmission assembly or a sprocket transmission assembly, etc.

[0024] To further ensure the coating effect of talcum powder on the outer periphery of the cable, refer to Figure 1 , Figure 2 and Figure 3 The powder spraying mechanism includes a support cylinder 61 coaxially arranged at both ends of the powder box 3, a powder storage ring 62 coaxially installed on the inner wall of the support cylinder 61, and an air pump 63 connected to the powder storage ring 62. The support cylinder 61 includes a straight cylinder portion 611 and a horn cylinder 612, and the straight cylinder portion 611 and the horn cylinder 612 are coaxially connected. One end of the straight cylinder portion 611 is fixedly installed on the frame 2, and the other end extends into the powder box 3 and is rotatably connected to the end of the powder box 3 through a rotating bearing. The horn cylinder 612 is located in the powder box 3, and the caliber of the horn cylinder 612 gradually increases in the direction away from the straight cylinder portion 611. The powder storage ring 62 is located on the inner wall of the horn 612, and the inside of the powder storage ring 62 is hollow, and the powder storage ring 62 is spaced to form a plurality of independent chambers 7 along its circumference, and talcum powder is contained in the independent chamber 7, and a plurality of powder outlets 9 are provided on the inner wall of the powder storage ring 62, and the powder box 3 is connected with the independent chamber 7 through the powder outlet 9, and the air pump 63 is connected with the plurality of independent chambers 7 through the pipeline. When it is necessary to spray talcum powder on the cable part located in the powder box 3, the air pump 63 can be started, and the air pump 63 blows the talcum powder in the independent chamber 7 into the powder box 3 through the powder outlet 9, so that the talcum powder is sprayed on the outer periphery of the cable. The excess talcum powder falls on the inner wall of the horn 612, and flows to the powder box 3 along the inner wall of the horn 612 under the action of gravity, so that the excess talcum powder can be driven by the powder box 3 to be poured on the outer periphery of the cable again.

[0025] The implementation principle of the twisting device for processing a multi-core stranded cable in the embodiment of the present application is as follows: first, the cable is twisted through the twisting machine 1, and then the twisted cable is sequentially passed through the straight barrel 611, the horn 612 and the powder box 3. As the cable is transmitted forward, the motor and the air pump 63 are started, and the air pump 63 blows the talcum powder in the multiple independent chambers 7 out of the powder outlet 9 through the pipeline, so that the talcum powder is sprayed on the outer periphery of the cable; and the excess talcum powder falls on the inner wall of the horn 612, and flows into the powder box 3 along the inner wall of the horn 612 under the action of gravity. The motor drives the powder box 3 to rotate through the belt and the pulley, and the talcum powder at the bottom of the powder box 3 is lifted to a certain height under the drive of the baffle 8. As the powder box 3 continues to rotate, the talcum powder brought by the baffle 8 is poured downward under the action of gravity, and the talcum powder in the falling process is poured to the outer periphery of the cable. The excess talcum powder slides down toward the middle of the powder box 3 under the guidance of the obliquely arranged baffle bar 8, ensuring that sufficient talcum powder can be collected and sprinkled later.

[0026] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
