Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable processing technology, specifically to an ultraviolet irradiation crosslinking device. Background Technology
[0002] In the high-end cable manufacturing field, the geometric uniformity and operational stability of the wire core are core factors determining the electrical performance, mechanical strength, and service life of the product. Ultraviolet (UV) irradiation crosslinking, as a crucial step in improving the performance of cable insulation, directly impacts the reliability of the finished product. However, traditional UV irradiation crosslinking equipment suffers from significant technical defects in actual production. During high-speed traction, the wire core is susceptible to interference from mechanical vibration, equipment resonance, and tension fluctuations, leading to slight displacement or jitter in the core's position. This results in uneven distribution of UV irradiation energy, causing differences in crosslinking degree and fluctuations in material properties. Furthermore, existing equipment often relies on mechanical guide wheels or contact sensors for core positioning, which suffers from response lag, insufficient accuracy, and susceptibility to wear and scratches on the core surface. This makes it difficult to achieve high-precision and stable control under dynamic operating conditions, resulting in reduced yield and increased production costs. Utility Model Content
[0003] The main purpose of this invention is to provide an ultraviolet irradiation crosslinking device to solve the problems of existing technologies that rely on mechanical guide wheels or contact sensors for core positioning, resulting in slow response, insufficient accuracy, and easy wear and scratching of the core surface. This makes it difficult to achieve high-precision and stable control under dynamic working conditions, leading to reduced product yield and increased production costs.
[0004] To achieve the above objectives, this utility model provides an ultraviolet irradiation crosslinking device, including a shaft tube;
[0005] One end of the shaft tube is fixed to the inlet or outlet of the irradiation body, the wire core passes through the shaft tube coaxially, and the end of the shaft tube away from the irradiation body is fixed with a ring shell.
[0006] Two inclined slides are symmetrically inclined on one side wall of the annular shell;
[0007] Each inclined slide has a guide block installed inside, a bracket is fixed on the guide block, and a laser pointer is installed on the bracket.
[0008] A rotating ring is rotatably embedded inside the ring shell. The rotating ring is connected to a driving component for driving its rotation. The rotating ring has two arc-shaped slides, and a guide rod slides in each arc-shaped slide. One end of the guide rod is fixedly connected to a guide block.
[0009] The driving component drives the rotating ring to rotate, causing the two laser pointers to move away from or towards the wire core synchronously.
[0010] Preferably, both laser pointers are arranged radially along the shaft tube, with the emission port facing the axial direction of the shaft tube.
[0011] Preferably, it further includes at least one L-shaped plate, the two ends of which are fixedly connected to the outer wall of the annular shell and the outer wall of the shaft tube, respectively.
[0012] Preferably, the ring shell includes a first ring plate, a ring, a second ring plate and a plurality of first bolts. The first ring plate, the ring and the second ring plate are coaxially stacked in sequence. The plurality of first bolts are circumferentially arranged on one side wall of the second ring plate and are screwed through the second ring plate, the ring and the first ring plate in sequence to connect to the first nut.
[0013] The inner ring of the ring, along with the inner walls of the first and second ring plates, forms an annular cavity. The rotating ring is embedded in the annular cavity, and two inclined slides are opened on the second ring plate.
[0014] Preferably, the driving component includes a ring spur gear, a drive spur gear, and a rotating shaft;
[0015] A ring-shaped spur gear is coaxially sleeved on a rotating ring. The ring has a notch. The rotating shaft is rotatably mounted on a second ring plate, and one end of the shaft passes through the notch to sleeve a driving spur gear. The driving spur gear meshes with the ring-shaped spur gear.
[0016] Preferably, a rotating handle is fixed at the end of the shaft away from the drive spur gear.
[0017] Preferably, the second ring plate has a threaded hole through it, and a fourth bolt is screwed into the threaded hole, with the fourth bolt abutting against the rotating ring.
[0018] Preferably, the bracket includes a mounting plate and a clamp, and the mounting plate is fixedly connected to the guide block;
[0019] The hoop includes two arc-shaped plates, multiple second bolts and multiple third bolts. Horizontal ear plates are fixed at both ends of each arc-shaped plate. The second bolts are screwed to the horizontal ear plates of the two arc-shaped plates in sequence to connect to the second nuts. The third bolts pass through any arc-shaped plate and the mounting plate in sequence to connect to the third nuts.
[0020] The laser pointer is clipped between two curved plates.
[0021] The beneficial effects of the above scheme are:
[0022] The wire core enters the ultraviolet irradiation equipment at a set speed, and the ultraviolet irradiation cross-linking devices at both ends start synchronously. A laser pointer emits a high-precision beam to monitor the actual position of the wire core in real time and feeds the data back to the control system. The laser pointer continuously scans the surface of the wire core, and if any deviation or jitter is detected, the system immediately triggers a response. Non-contact laser detection avoids the frictional wear of traditional mechanical guide wheels, extending the equipment's lifespan and reducing the risk of scratches on the wire core surface. When changing to wire cores of different diameters, the drive component rotates the rotating ring. The arc-shaped slide on the rotating ring pushes the guide rod and guide block to slide along the inclined slide of the ring shell. The guide block drives the bracket and laser pointer to move away from or closer to the wire core synchronously. Adjusting the distance between the laser pointer and the wire core ensures uniform irradiation energy distribution and reduces differences in cross-linking degree. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0032] Example:
[0033] like Figures 1-5 As shown, this embodiment provides an ultraviolet irradiation crosslinking device, including a shaft tube 1. One end of the shaft tube 1 is fixed to the inlet core 100 or outlet core 100 of the irradiation body (not shown). The irradiation body adopts existing technology, so it will not be described in detail. Please refer to patent publication number: CN112117055B - Chinese Invention Patent: A Crosslinking Cable Ultraviolet Irradiation Device or CN207990229U - Chinese Utility Model Patent: A High-Efficiency Energy-Saving Ultraviolet Irradiation Device for LEDs. The core 100 coaxially passes through the shaft tube 1, as shown. Figure 1 As shown, the end of the shaft tube 1 furthest from the irradiation body is fixedly fitted with an annular shell 2. Two inclined slides 21 are symmetrically inclined on one side wall of the annular shell 2. A guide block 2 slides within each inclined slide 21, and a bracket 3 is fixed on the guide block 2. A laser pointer 4 is mounted on the bracket 3. A rotating ring 5 is rotatably embedded within the annular shell 2, as shown... Figure 4 As shown, the annular shell 2 includes a first annular plate 22, an annular ring 23, a second annular plate 24, and multiple first bolts 25. The first annular plate 22, the annular ring 23, and the second annular plate 24 are coaxially stacked. The multiple first bolts 25 are circumferentially arranged on one side wall of the second annular plate 24, and the first bolts 25 pass through the second annular plate 24, the annular ring 23, and the first annular plate 22 in sequence to be screwed with a first nut 26. The inner ring of the annular ring 23, the inner wall of the first annular plate 22, and the inner wall of the second annular plate 24 form an annular cavity. The rotating ring 5 is embedded in the annular cavity (not shown), and two inclined slides 21 are provided on the second annular plate 24. The rotating ring 5 is connected to a driving component 6 for driving its rotation. The rotating ring 5 has two arc-shaped slides 51, and a guide rod 52 slides in each arc-shaped slide 51. One end of the guide rod 52 is fixedly connected to the guide block 2. The guide rod 52 can limit the rotation of the rotating ring 5, so that the rotating ring 5 can rotate around the axial direction of the shaft tube 1. The driving component 6 drives the rotating ring 5 to rotate, causing the two laser pointers 4 to simultaneously move away from or towards the wire core 100. Both laser pointers 4 are arranged radially along the shaft tube 1, and their emission ports face the axial direction of the shaft tube 1. Figure 2 , Figure 4As shown, the driving component 6 includes a ring-shaped spur gear 61, a driving spur gear 62, and a rotating shaft 63. The ring-shaped spur gear 61 is coaxially sleeved on the rotating ring 5. The ring 23 has a notch 230. The rotating shaft 63 is rotatably mounted on the second ring plate 24, and one end of the rotating shaft 63 passes through the notch 230 to sleeve the driving spur gear 62, which meshes with the ring-shaped spur gear 61. A rotating handle 64 is fixed to the end of the rotating shaft 63 away from the driving spur gear 62. When the operator rotates the rotating handle 64, the rotating handle 64 drives the driving spur gear 62 to rotate via the rotating shaft 63, and the driving spur gear 62 drives the rotating ring 5 to rotate via the ring-shaped spur gear 61. Figure 1 As shown, the second ring plate 24 has a threaded hole (not shown) through it, and the fourth bolt 8 is screwed into the threaded hole. The purpose of the fourth bolt 8 abutting against the rotating ring 5 is to limit the rotation ring 5.
[0034] The wire core 100 enters the ultraviolet irradiation equipment at a set speed, and the ultraviolet irradiation crosslinking devices at both ends are activated simultaneously. The laser pointer 4 emits a high-precision beam to monitor the actual position of the wire core 100 in real time. The laser pointer 4 continuously scans the surface of the wire core 100, and if any deviation or jitter is detected, a response is immediately triggered. Non-contact laser detection avoids the frictional wear of traditional mechanical guide wheels, extends the equipment life, and reduces the risk of scratches on the surface of the wire core 100. When replacing the wire core 100 with a different diameter, the drive component 6 drives the rotating ring 5 to rotate. The arc-shaped slide 51 on the rotating ring 5 pushes the guide rod 52 and the guide block 2 to slide along the inclined slide 21. The guide block 2 drives the bracket 3 and the laser pointer 4 to move away from or closer to the wire core 100 simultaneously, adjusting the distance between the laser pointer 4 and the wire core 100 to ensure uniform irradiation energy distribution and reduce differences in crosslinking degree.
[0035] The ultraviolet irradiation crosslinking device also includes at least one L-shaped plate 7, the two ends of which are fixedly connected to the outer wall of the annular shell 2 (i.e., the side wall of the first annular plate) and the outer wall of the shaft tube 1, respectively. The L-shaped plate 7 secures the annular shell 2 to the shaft tube 1. The bracket 3 includes a mounting plate 31 and a clamp 32, the mounting plate 31 being fixedly connected to the guide block 2. The clamp 32 includes two arc-shaped plates 321, multiple second bolts 322, and multiple third bolts (not shown). Horizontal ear plates 324 are fixedly installed at both ends of each arc-shaped plate 321. The second bolts 322 sequentially screw the horizontal ear plates 324 of the two arc-shaped plates 321 to the second nuts 325. The third bolts sequentially pass through any arc-shaped plate 321 and the mounting plate 31 to the third nuts (not shown). A laser pointer 4 is clamped between the two arc-shaped plates 321.
[0036] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
