Description

Technical Field

[0001] The utility model relates to the technical field of cables, and more particularly to a drag chain cable for a laser cutting machine. Background Art

[0002] Drag chain cables, designed specifically for mechanical equipment such as laser cutting machines, play a vital role. During the operation of the laser cutting machine, the drag chain cable bears the heavy responsibility of connecting key equipment such as the laser transmission harness and cooling water pipes. It can slide flexibly with the movement of the laser head to ensure the precise transmission of the laser beam and the smooth operation of the cooling system. The softness and wear resistance of the drag chain cable enable it to maintain stable performance in an environment with frequent bending and pulling, effectively preventing the cable from being damaged by mechanical movement. This feature not only extends the service life of the cable, but also ensures the continuous and efficient operation of the laser cutting machine. The drag chain cable also has good protective performance and can resist interference from the external environment, such as dust, oil, etc., further ensuring the stable operation of the laser cutting machine. The drag chain cable plays an indispensable role in the laser cutting machine and provides a solid guarantee for the efficient and safe operation of the equipment.

[0003] Existing technology is deficient: Network signal interference can distort the control signal transmission of the laser cutting machine, resulting in inaccurate movement of the laser cutting head and, in turn, impacting cutting quality. Drag chain cables with poor tensile strength are more susceptible to breakage when subjected to the frequent movement and tension of the laser cutting machine. This not only causes sudden equipment shutdowns but also poses a safety hazard to operators. Twisting can cause the cable's core wires, insulation, and other structures to twist and deform, potentially leading to electrical faults such as short circuits and open circuits. Prolonged twisting can also accelerate cable aging, shortening its service life. Utility Model Content

[0013] 2. The utility model adopts aluminum foil and tinned braided shielding structure for signal lines, which is beneficial to the electromagnetic radiation generated by the power line during operation, causing interference to the signal line and network line, resulting in signal attenuation.

[0015] 4. The utility model is provided with TPU sheaths for both inner and outer protection. The TPU material has excellent resistance to bending fatigue and can maintain its original physical and chemical properties after multiple bending and recovery.

All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Reference Figures 1 to 4 The utility model provides a drag chain cable for a laser cutting machine, comprising an outer sheath unit 1, the inner ring side wall of the outer sheath unit 1 is fixedly connected with a shielding anti-torsion layer 2, the inner ring side wall of the shielding anti-torsion layer 2 is fixedly connected with an inner sheath unit 3, the inner ring side wall of the inner sheath unit 3 is fixedly connected with an aramid reinforced filling layer 7, the inner ring side wall of the inner sheath unit 3 is fixedly connected with a first insulating layer 4, the inner ring side wall of the first insulating layer 4 is fixedly connected with a bare copper wire conductor 401, the inner ring side wall of the inner sheath unit 3 is fixedly connected with a second insulating layer 5, the inner ring side wall of the second insulating layer 5 is fixedly connected with a network cable unit 501, the inner ring side wall of the inner sheath unit 3 is fixedly connected with a third insulating layer 6, and the inner ring side wall of the third insulating layer 6 is fixedly connected with a protective layer 601.

[0023] Among them, the inner circle side wall of the second insulating layer 5 is movably connected to the network cable protection layer 502, and the inner circle side wall of the network cable protection layer 502 is fixedly connected to the network cable 503. The network cable unit 501 is the transmission channel of the network signal, and the network cable protection layer 502 further protects the network cable 503 from damage from the external environment. The network cable 503 is responsible for transmitting control signals and data from the control system to the various control units of the laser cutting machine.

[0024] Among them, the inner circle side wall of the protective layer 601 is fixedly connected to the signal line shielding unit 602, and the inner circle side wall of the signal line shielding unit 602 is fixedly connected to the wire 603. The third insulating layer 6 is wrapped around the outside of the protective layer 601 to play an additional insulating and protective role. It ensures the safe transmission of the internal signal line and prevents electrical interference and mechanical damage. The protective layer 601 adopts aluminum foil and tin-plated deteriorated structure to provide a good electromagnetic shielding effect. The signal line shielding unit 602 further enhances the shielding performance of the signal line and prevents the influence of external electromagnetic interference on the signal line. It ensures that the signal line can transmit control signals and data stably and without attenuation during the transmission process.

[0025] Among them, the material of the shielding torsion-resistant layer 2 is woven with aramid and tinned copper wire. This layer mainly plays three roles: one is to enhance the overall tensile strength of the cable; the second is to prevent the cable from twisting during suspension or movement, protecting the internal wire core from mechanical damage; the third is to serve as an electromagnetic shielding layer to reduce the impact of external electromagnetic interference on internal signal lines and network lines.

[0026] Among them, the material of the aramid reinforced filling layer 7 is aramid reinforced filling, located in the center of the cable, and is reinforced with aramid material. Its main function is to significantly improve the overall tensile strength of the cable.

[0028] Working principle of this utility model: As the outermost layer of the cable, TPU material provides excellent wear resistance, weather resistance and chemical corrosion resistance, protecting the internal structure from the influence of the external environment. It is woven from aramid and tinned copper wire. This layer not only enhances the overall strength of the cable, but also prevents the cable from twisting during hanging or moving through its woven structure. At the same time, the tinned copper wire braided layer also plays the role of electromagnetic shielding, reducing the influence of external electromagnetic interference on internal signal lines and network lines. TPU material is also used to provide additional protection and support for each internal layer. It is located in the center of the cable and is reinforced with aramid material, which significantly improves the overall tensile strength of the cable. When the laser cutting machine moves frequently and bears tension, aramid can effectively disperse and withstand these forces to prevent the cable from being damaged due to excessive stretching. The first insulating layer 4 wraps the bare copper wire conductor 401 to ensure the safety of power transmission. The second insulating layer 5 and the network cable protective layer 502 jointly protect the network cable unit 501 and the network cable 503 to prevent signal interference and physical damage. The third insulating layer Layer 6 wraps the protective layer 601 to further isolate and protect the internal signal line. The protective layer adopts aluminum foil and tinned modified structure to enhance the shielding performance of the cable. The signal line shielding unit 602 further ensures that the signal line is not affected by external electromagnetic interference during transmission. The bare copper wire conductor 401 is isolated and protected by the first insulation layer 4 to safely transmit power to various components of the laser cutting machine. The network cable unit 501 and the network cable 503 are protected by the second insulation layer 5 and the network cable protective layer 502, as well as the electromagnetic shielding of the signal line shielding unit 602 to ensure that the signal is stable and attenuated during transmission. The shielding anti-torsion layer 2 is woven with aramid and tinned copper wire to effectively prevent the cable from being damaged during twisting and enhance the overall tensile strength of the cable. The aramid reinforced filling layer 7 further improves the tensile performance of the cable. The inner and outer sheaths are made of TPU material, which uses its excellent bending fatigue resistance to ensure that the cable can maintain its original physical and chemical properties when the laser cutting machine moves and bends frequently, thereby extending the service life of the cable.
