Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cable processing, in particular to an ultraviolet radiation cross-linking device for producing low-smoke halogen-free flame-retardant wires and cables. Background Art
[0002] Low-smoke halogen-free flame-retardant wires and cables refer to environmentally friendly cables made of rubber materials that do not contain halogens, lead, cadmium, chromium, mercury and other environmental substances and do not emit toxic smoke when burned.
[0003] Cross-linked cables are generally manufactured by radiation cross-linking. After a layer of plastic protective layer is injected on the outside of the cable conductor, the plastic protective layer is heated and cured. In order to shorten the curing time, ultraviolet light curing technology is used to cure the plastic protective layer.
[0004] When the cable is subjected to ultraviolet irradiation, it needs to be fed into the irradiation cross-linking device. Traditional feeding relies on manual work, where the cable is pulled from the outlet and fed into the device. Since the ultraviolet irradiation inside the equipment will heat the cable structure, manual feeding is prone to uneven irradiation time, which damages the cable structure during the feeding process. The irradiation degree of each part of the cable is uneven, which reduces the quality of cable production and increases safety risks for subsequent cable use.
[0005] Based on this, a UV irradiation cross-linking device for the production of low-smoke halogen-free flame-retardant wires and cables is proposed. Utility Model Content
[0006] The purpose of the utility model is to solve the above problems and to propose an ultraviolet radiation cross-linking device for the production of low-smoke halogen-free flame-retardant wires and cables.
[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0008] A device for ultraviolet radiation cross-linking used in the production of low-smoke halogen-free flame-retardant wires and cables comprises a body, the lower end of which is connected to a support seat, one side of which is connected to an inlet pipe and a fixing frame, one end of which is connected to a guide pipe, and one side of which is connected to a conveying mechanism for conveying the cable into the body to complete ultraviolet radiation.
[0009] Preferably, the conveying mechanism includes a reciprocating ring, a slide is connected between the guide tube and the machine body, the reciprocating ring is slidably connected to the slide, the outside of the machine body is connected to a motor frame, a rotating motor is connected to the motor frame, the output end of the rotating motor is connected to a turntable, the turntable is connected to column one, and the column one is rotatably connected to a traction rod.
[0010] Preferably, a slide groove is provided on the slide, the lower end of the reciprocating ring is connected to a slider, the slider is slidably connected to the slide groove, and the lower end of the slider is connected to column 2.
[0011] Preferably, the sliding block is connected to a limiting block, and the limiting block is slidably arranged on the slide.
[0012] Preferably, a transmission block is rotatably connected to the reciprocating ring, and a one-way belt is connected to the transmission block.
[0013] Preferably, a connecting pipe is connected to the inner side of the reciprocating ring, a deflection frame is rotatably connected to the connecting pipe, the transmission block is rotatably connected to the deflection frame, and a torsion spring is provided at the connection between the connecting pipe and the deflection frame.
[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0015] 1. The present application adopts a reciprocating ring structure, which can be used to feed the cable into the machine body. Since a one-way belt structure is provided on the reciprocating ring, when the transmission block moves along the direction of cable feeding, the one-way belt stops rotating, thereby achieving a feeding effect. When the transmission block moves in the opposite direction of the cable feeding, the one-way belt starts to rotate, avoiding damage to the outside of the cable. In addition, by providing a torsion spring structure, it is ensured that the transmission block can clamp the cable at all times, ensuring a stable feeding effect.
[0016] 2. The present application adopts a guide tube structure, which can be used to straighten the cable in advance when feeding the cable, thereby ensuring the stability of the reciprocating movement of the reciprocating ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] See also Figure 1-3 , the utility model provides a technical solution:
[0024] A device for ultraviolet radiation cross-linking for the production of low-smoke, halogen-free, flame-retardant wires and cables comprises a body 1, a support base 2 being connected to the lower end of the body 1, the support base 2 ensuring the structural stability of the body 1, an inlet pipe 3 and a fixing frame 4 being connected to one side of the body 1, a guide pipe 6 being connected to one end of the fixing frame 4, and a conveying mechanism being connected to one side of the guide pipe 6 for conveying the cable into the body 1 for ultraviolet radiation.
[0025] Specifically, such as Figure 1 and Figure 2 As shown, the conveying mechanism includes a reciprocating ring 10, a slide 5 is connected between the guide tube 6 and the body 1, the wire feed pipe 3 is arranged between the fixed frame 4 and the slide 5, the reciprocating ring 10, the guide tube 6 and the wire feed pipe 3 are on the same axis, the reciprocating ring 10 is slidably connected to the slide 5, the outside of the body 1 is connected to the motor frame 7, the motor frame 7 is connected to the rotating motor 8, the motor frame 7 is utilized to improve the firmness of the connection of the rotating motor 8, the output end of the rotating motor 8 is connected to a turntable 12, the turntable 12 is connected to a column 13, the column 13 is rotatably connected to a traction rod 11, and the other end of the traction rod 11 is rotatably connected to a column 2 14.
[0026] Specifically, such as Figure 1 and Figure 2 As shown, a slide groove 9 is provided on the slide 5, and the slide groove 9 is a through structure. The lower end of the reciprocating ring 10 is connected to a slider 15, and the slider 15 is slidably connected to the slide groove 9, and the lower end of the slider 15 is connected to the column 2 14.
[0027] Specifically, such as Figure 3 As shown, the slider 15 is connected to a limit block 16 , and the limit block 16 is slidably arranged on the slide 5 . By setting the limit block 16 , the sliding stability of the slider 15 is improved.
[0028] Specifically, such as Figure 3 As shown, a transmission block 19 is rotatably connected to the reciprocating ring 10, and a one-way belt 20 is connected to the transmission block 19. The one-way belt 20 is similar to the ratchet structure of the rear wheel of a current bicycle, ensuring that the one-way belt 20 can only perform one-way transmission.
[0029] Specifically, such as Figure 3 As shown, a connecting tube 17 is connected to the inner side of the reciprocating ring 10, a deflection frame 18 is rotatably connected to the connecting tube 17, a transmission block 19 is rotatably connected to the deflection frame 18, and a torsion spring is provided at the connection between the connecting tube 17 and the deflection frame 18. By providing the torsion spring structure, the clamping effect of the transmission block 19 on the cable is ensured.
[0030] In summary, the present embodiment provides a UV irradiation cross-linking device for the production of low-smoke halogen-free flame-retardant wires and cables. When the cable needs to be fed into the UV irradiation cross-linking device, the cable needs to be sequentially passed through the guide tube 6, the reciprocating ring 10, and the inlet tube 3 structure, and finally led out from the other end of the device. In order to ensure that the cables arranged in the device can be evenly irradiated with UV light, the rotating motor 8 can be set to an intermittent operation state;
[0031] When the rotating motor 8 is started, the turntable 12 starts to rotate. The turntable 12 cooperates with the column 13 to pull the traction rod 11 to move. One end of the traction rod 11 is rotatably connected to the column 2 14. At this time, the traction rod 11 can pull the slider 15 to move back and forth on the slide 9.
[0032] When the reciprocating ring 10 moves back and forth with the slider 15, when the reciprocating ring 10 extends the direction of cable entry, the transmission block 19 cooperates with the one-way belt 20 to clamp the outer side of the cable. At this time, the one-way belt 20 does not rotate around the transmission block 19. The one-way belt 20 here is similar to the rear wheel of a bicycle today. The specific structure will not be described in detail. At this time, the one-way belt 20 can easily feed the cable into the body 1;
[0033] On the contrary, when the reciprocating ring 10 is opposite to the direction of cable entry, the unidirectional belt 20 structure rotates, achieving the effect of moving the reciprocating ring 10 while the cable structure does not move. After the reciprocating ring 10 moves back and forth, the cable can be easily fed into the body 1 to complete the ultraviolet irradiation operation, wherein the ultraviolet irradiation time of each section of cable is the same, thereby improving the quality of cable processing.

Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
