Description

Technical Field

[0001] This invention relates to the field of cable extrusion production technology, and in particular to an online coaxiality adjustment device and process for high-speed shielded mesh cable extrusion. Background Technology

[0002] In the extrusion production of network cables, such as data cables and LAN cables, the coaxiality of the inner conductor core and the outer insulation layer is a core quality indicator that determines the signal transmission performance, electrical consistency, and product qualification rate of the network cable. Current mainstream network cable extrusion production lines are equipped with online coaxiality detection devices to monitor the coaxiality deviation of the extruded cable in real time.

[0003] Patent document CN114459389A discloses a coaxiality detection method and system, relating to the field of coaxiality detection. First, a rotating shaft device responds to a start command sent by a control device, rotating the workpiece to be inspected at a preset rate. Then, an image acquisition device responds to an image acquisition command sent by the control device, acquiring multiple images of the end faces of the workpiece to be inspected according to a preset cycle, and uploading these images to the control device. Next, the control device extracts the center point position information of the end face in each image. Finally, the control device obtains the coaxiality between the workpiece to be inspected and the rotating shaft device based on the center point position information of the end faces in all images.

[0004] However, in actual use, the inventors found that when the coaxiality was detected to be outside the tolerance range, the production line had to be stopped to manually adjust the position of the extrusion die and manually cut off the defective cable sections. Frequent start-ups and shutdowns not only directly caused production interruptions and low capacity utilization, but also led to fluctuations in process parameters such as extrusion temperature and pressure, further increasing the length of defective sections.

Limiting stops are provided on both sides of the receiving channel to limit the transmission linkage of the flipping and lifting mechanism. After the flipped wire enters the electric clamping roller group, the electric clamping roller group clamps it and drives the wire to move toward the straight cutting blade to complete the opening action. The rubbing and peeling assembly includes a lifting frame driven by a fourth pneumatic drive unit to perform lifting and lowering movements, two sets of elastic paddles elastically installed on the lifting frame and arranged in a figure-eight shape, and rubbing clamps fixedly installed on the lifting frame and respectively located on both sides of the elastic paddles.

[0010] Furthermore, the sorting and collecting unit includes a core winding assembly and an insulation layer collecting assembly; The wire core winding assembly includes a three-axis transmission mechanism mounted on the equipment frame, and a winding execution unit mounted on the output end of the three-axis transmission mechanism.

If the thickness reaches the specified value range, it is unloaded into one set of temporary storage racks; otherwise, it is unloaded into another set of temporary storage racks.

[0014] Furthermore, it also includes a die head coaxiality adjustment mechanism, which includes a die core adjusting fastener disposed at the extrusion die head of the extrusion mechanism for adjusting the coaxiality of the extrusion die core online.

[0015] A coaxiality-controlled extrusion production process for network cables, implemented using the aforementioned high-speed shielded network cable extrusion coaxiality-adjustment equipment, includes the following steps: S1. Extrusion and shaping: The extrusion mechanism extrudes the forming wire, which is then cooled and shaped by the cooling and shaping mechanism and conveyed to the coaxiality online detection mechanism. S2. Coaxiality Detection: The online coaxiality detection mechanism performs real-time online detection of the coaxiality between the wire core and the insulation layer of the network cable. If the coaxiality deviation is within the preset threshold, it is judged as a qualified product and directly conveyed to the finished product winding device to complete the winding. If the coaxiality deviation exceeds the preset threshold, it is judged as a non-qualified product and step S3 is executed. S3. Separation and Recycling of Non-conforming Products: The traction device clamps and conveys the non-conforming section of the wire, the transfer and cutting unit cuts the non-conforming section of the wire and lifts it for transfer; during the transfer process, the insulation layer peeling and sorting unit peels the insulation layer from the wire core, and the classification and collection unit classifies and collects the peeled wire core and insulation layer separately; at the same time, the extrusion mechanism adjusts the extrusion coaxiality online through the die head coaxiality adjustment mechanism. S4. Qualified Continuous Production: When the online coaxiality detection mechanism detects qualified products again, the transfer and cutting unit cuts and separates the unqualified section from the qualified section. The unqualified section is continuously conveyed and collected. The qualified product is conveyed to the finished product winding device by the traction device. The tail end continuation unit fixes the starting end of the qualified wire to the new winding roller of the winding unit and resumes normal winding, realizing continuous non-stop production. S5. Rewinding and finishing: When the qualified wire mesh is wound to the set diameter, the end-connecting unit cuts tape to a fixed length and sticks it to the end of the wire mesh to complete the winding and fixing of the wire mesh. The finished product is then unloaded and the empty roller is replaced by the automatic roll changing and unloading device.

[0016] The beneficial effects of this invention are: (1) This invention constructs a closed-loop continuous production system with online coaxiality detection, real-time die head adjustment, online bypass rejection of defective products, and automatic rewinding of qualified products. When coaxiality deviation is detected, there is no need to shut down the entire line. While the extrusion die head is adjusted online, the defective cable section is rejected, stripped, and sorted through an independent waste separation and recycling bypass. Qualified products are automatically rewound, thus solving the production interruption problem caused by the traditional production line shutdown for die adjustment and manual material cutting. Production continuity and output per unit time are improved. At the same time, it avoids the fluctuation of extrusion temperature and pressure caused by frequent start-stop, reduces defective products caused by process fluctuations, and further improves the overall yield. (2) This invention features a special insulation stripping and sorting unit and a classification and collection unit for substandard network cables. It employs a two-step separation structure with axial opening and figure-eight twisting stripping, enabling precise online automatic separation of the insulation layer from the internal copper core. The separated metal core is neatly wound up by a core winding assembly and can be directly recycled; the insulation layer is collected by a guide rack and can be recycled. Compared to traditional methods of discarding entire sections, this invention significantly improves the recycling rate of metal and insulation materials.

[0017] (3) The finished product winding device of the present invention is equipped with a tail-end splicing unit, which adopts a combination structure of needle-type tape gripping, circular rotary feeding and lifting and pressing bonding. It can automatically complete the entire process of tape length cutting, wire mesh starting end pasting and fixing, and winding tail end pasting without human intervention. With the help of the automatic roll changing and unloading device, it can realize full roll automatic unloading, empty roller automatic replacement, roll diameter automatic detection and sorting, and the winding joint bonding firmness is uniform and consistent. It solves the pain points of low efficiency and unstable quality of manual splicing, and avoids the safety risks of manual approach to the operating mechanism.

[0018] (4) This invention forms a closed-loop control between the online coaxiality detection mechanism and the mold head coaxiality adjustment mechanism, and feeds the detection data back to the adjustment actuator in real time to achieve dynamic online correction of coaxiality. Compared with the traditional method of manual mold adjustment during shutdown, the adjustment response speed is faster and the adjustment accuracy is higher. It can stably control the coaxiality deviation of the network cable within a very small tolerance range, and significantly improve the electrical performance and batch quality consistency of the product.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] Example 1 like Figure 2-13 As shown, a coaxiality online adjustment device for high-speed shielded wire extrusion includes an extrusion mechanism, a cooling and shaping mechanism 2, and a coaxiality online detection mechanism 3 arranged sequentially along the wire production direction. It also includes a traction device 4, a waste separation and recycling device 5, and a finished product winding device 6, which are sequentially arranged downstream of the coaxiality online detection mechanism 3 along the production direction; The waste separation and recycling device 5 includes a transfer and cutting unit 51 located at the output end of the traction device 4 and installed on the transfer frame, an insulation stripping and sorting unit 52 located above the transfer and cutting unit 51, and a sorting and collecting unit 53 for sorting and collecting the sorted wire cores and insulation layers. The finished product winding device 6 includes a winding unit 61 for winding qualified network cables, and a tail end splicing unit 62 disposed below the winding unit 61 for quantitatively cutting and pasting tape to the tail end of the network cable.

[0035] The coaxiality online detection mechanism 3 uses a laser diameter measuring coaxiality detector, which can detect the insulation layer thickness, core eccentricity and coaxiality deviation of the network cable in real time, and feed the detection data back to the equipment control system.

[0036] As a preferred option, such as Figure 3-4 As shown, the traction device 4 includes two sets of circulating traction chains 41 arranged side by side and circulating along the direction of the network cable conveying, a guide cam rail 42 extending along the direction of the circulating traction chains 41, and a drive assembly. The circulating traction chain 41 is evenly provided with several sets of clamping units 411 along the running direction. Each set of clamping units 411 includes a mounting base installed on the circulating traction chain 41 and a clamping claw elastically connected to the mounting base. The guide cam rail 42 includes a release section 421 and a clamping section 422 that are smoothly connected. The bottom of the clamping jaw is provided with a guide slider 4113. The guide slider 4113 is adapted to be embedded in the guide cam rail 42. The clamping jaw opens and closes as the trajectory of the guide cam rail 42 changes, thereby realizing the clamping and release of the network cable. The drive assembly includes a first pneumatic drive element for driving the guide cam rail 42 to translate horizontally.

[0037] In this embodiment, the traction device adopts a cam track type cyclic clamping structure. The opening and closing timing and clamping force of the clamping jaws are precisely controlled by the trajectory change of the guide cam track 42. The conveying positioning accuracy is high and it can be adapted to the conveying of network cables of different diameters. The cyclic structure realizes uninterrupted continuous conveying, and the conveying efficiency is much higher than that of traditional clamping traction structures.

[0038] When the clamping unit 411 moves to the clamping section with the chain, the guide slider 4113 moves inward along the track, driving the clamping jaws on both sides to close, clamping both sides of the wire mesh and conveying the material forward; when it reaches the release section, the guide slider 4113 moves outward, and the clamping jaws open to release the wire mesh. The first pneumatic drive unit can drive the guide cam rail 42 to move horizontally as a whole, adjusting the opening and closing stroke of the clamping jaws 4002 to adapt to wire meshes of different diameters.

[0039] As a preferred option, such as Figure 7 As shown, the transfer and cutting unit 51 includes: The cutting assembly 511 includes a cutting base plate 5111 mounted on the transfer frame, a cutting blade 5112 disposed directly above the cutting base plate 5111, and a second pneumatic drive 5113 that drives the cutting blade 5112 to perform lifting and cutting actions. The second pneumatic drive 5113 drives the cutting blade to lift and lower to complete the cutting of the network cable. The first guide roller 512 is rotatably mounted on the transfer frame and is used for guiding and conveying the network cable. The guide support assembly 513 is disposed at the discharge end of the cutting base plate 5111, and two sets are symmetrically arranged along the length of the transfer frame. Each set of guide support assembly 513 includes a first guide seat 5131 with a first guide groove, a support plate 5132 rotatably hinged to the first guide seat 5131 by a first reset spring, and a first limiting block 5133 installed on the first guide seat 5131 and located below the support plate 5132. Under normal conditions, the support plate 5132 supports the wire mesh, and can rotate upward to make way when flipped and lifted. The flipping and lifting mechanism 514 includes a lifting pressure roller 5141, a material supporting assembly 5142, two sets of transmission connecting rods 5143, and a first servo drive mechanism 5144. The lifting pressure roller 5141 is mounted on a lifting mounting frame and is driven to perform lifting movements by a third pneumatic drive component 51411. The material supporting assembly 5142 is located on the lifting mounting frame and below the lifting pressure roller 5141. One end of each of the two sets of transmission connecting rods 5143 is connected to the lifting mounting frame, and the other end is connected to the transfer frame. The first servo drive mechanism 5144 is used to drive the transmission connecting rods 5143 to rotate, thereby driving the lifting mounting frame to complete the flipping and lifting action. Specifically, the first servo drive mechanism 5144 drives the connecting rods to rotate, thereby driving the entire lifting mounting frame to flip and lift upwards, pulling the cut defective wire from the normal channel and sending it into the stripping station above. Two sets of the material-bearing components 5142 are symmetrically arranged along the width direction of the transfer frame. Each set of material-bearing components 5142 includes a material-bearing plate 51421 that is rotatably hinged to the lifting mounting frame by a second reset spring, and a second limiting block 51422 that is fixed to the lifting mounting frame and located below the material-bearing plate 51421.

[0040] In this embodiment, by setting the transfer and cutting unit 51 to adopt a linkage-type flip-lifting structure, and with the elastic limiting design of the support plate and the material-bearing plate 51421, the cutting and lifting actions are smoothly connected, and there is no deviation or falling off during the cable transfer process, which provides a precise positioning basis for subsequent stripping and material separation.

[0041] As a preferred option, such as Figure 10-13 As shown, the insulation layer peeling and dispensing unit 52 includes a slitting assembly 521 and a rubbing peeling assembly 522 mounted on the equipment frame; The slitting assembly 521 includes a receiving channel 5211, an electric clamping roller group 5212, a straight cutting blade 5213, and a cutting anvil 5214 arranged sequentially along the material conveying direction. The receiving channel 5211 is provided with limit stops 5215 on both sides for limiting the transmission connecting rod 5143 of the flipping and lifting mechanism 514. After the flipped wire enters the electric clamping roller group 5212, the electric clamping roller group 5212 clamps it and drives the wire to move toward the straight cutting blade 5213. The straight cutting blade 5213 moves down and cuts a slit in the insulation layer along the axial direction. The rubbing and peeling assembly 522 includes a lifting frame 5222 driven by a fourth pneumatic drive 5221 to perform lifting and lowering movements, two sets of elastic paddles 5223 elastically mounted on the lifting frame 5222 and arranged in a figure-eight shape, and rubbing clamps 5224 fixedly mounted on the lifting frame 5222 and respectively disposed on both sides of the elastic paddles 5223.

[0042] During operation, the lifting frame 5222 moves downward, the elastic lever 5223 is embedded in the insulation layer cut, and the two side rubbing plates 5224 rub back and forth, which, together with the tension of the elastic lever, completely peels the insulation layer from the wire core.

[0043] In this embodiment, the insulation layer stripping and separating unit 52 adopts a step-by-step stripping process of opening first and then rubbing and stripping. After the straight cutting blade accurately cuts open the surface of the insulation layer, the figure-eight elastic shovel is embedded in the cut. With the reciprocating rubbing of the rubbing clamps on both sides, the insulation layer and the wire core can be completely separated. The stripping success rate is high and the internal conductor is not damaged, thus ensuring the reuse value of the recycled wire core.

[0044] Preferably, the sorting and collecting unit 53 includes a core winding assembly 531 and an insulation layer collecting assembly 532; The wire core winding assembly 531 includes a three-axis transmission mechanism 5311 mounted on the equipment frame, and a winding execution unit 5312 mounted on the output end of the three-axis transmission mechanism 5311. The winding execution unit 5312 includes a first winding shaft 53121, a wire core clamping head 53122 disposed on the first winding shaft 53121, and a material-pulling rod 53123 rotatably hinged to the equipment frame via a third reset spring. The material-pulling rod 53123 adopts an elastic telescopic structure and is driven to rotate by an external driving force. The wire core clamping head 53122 clamps the wire core and pulls it into the first winding shaft 53121. The first winding shaft 53121 rotates and moves the wire core clamping head 53122 to one side under the guidance of the material-pulling rod 53123, avoiding interference with the operation of the wire core clamping head 53122. The insulation layer collecting assembly 532 includes a guide frame that is fixedly installed on the equipment frame and arranged at an inclined downward direction, and a receiving box that is disposed at the discharge end of the guide frame.

[0045] It should be noted that after the wire core clamping head clamps the end of the wire core, the first winding shaft 53121 rotates to wind it up; the pressure rod 53124 descends and acts on the inclined surface of the feeding rod 53123, driving the feeding rod 53123 to swing, guiding the wound wire core to one side of the clamping head to avoid interference. The stripped insulation layer falls to the guide frame and slides into the collection box for centralized collection.

[0046] As a preferred option, such as Figure 8-9 As shown, the winding unit 61 includes a second guide seat 611 with a second guide groove, a second guide roller 612 disposed at the discharge end of the second guide seat 611, a variable diameter first mounting shaft 613, and a second servo drive mechanism 614. The first mounting shaft 613 is used to mount the second take-up roller, and the second servo drive mechanism 614 is used to drive the first mounting shaft 613 to perform circumferential rotation take-up motion.

[0047] Preferably, the tail-end splicing unit 62 includes a second mounting shaft 621, a third guide roller 622, a fourth guide roller 623, a tape cutter 624, a tape attaching rotary mechanism, and a pressing and lifting mechanism. The second mounting shaft 621 is rotatably mounted on the side plate of the equipment and is used to mount the tape roll; The third guide roller 622 is disposed on the side plate of the equipment and located above the second mounting shaft 621. The fourth guide roller 623 located on one side of the third guide roller 622 cooperates with the third guide roller 622 to form a belt conveying channel. The roller surface of the fourth guide roller 623 has multiple sets of clearance ring grooves 6231. The tape cutter 624 can reciprocate in the horizontal direction and cooperate with the third guide roller 622 to complete the fixed-length cutting of the tape. The tape-attaching rotary mechanism includes an annular guide rail 6251 coaxially formed on the side plate of the equipment with the second mounting shaft 621, a movable roller 6252 with transmission assembly within the annular guide rail 6251, and multiple sets of equally spaced, elastically embedded needle assemblies 6253. A third servo drive mechanism drives the movable roller 6252 to revolve around the second mounting shaft 621 via a connecting rod. The needle assembly 6253 is controlled by an independent drive unit to extend and retract. The needle assembly is telescopic and can be inserted into the tape for fixation when extended.

[0048] The clamping and lifting mechanism includes a clamping plate 6262 driven by a fifth pneumatic drive component and slidable vertically on the side plate of the equipment. The clamping plate 6262 has an arc-shaped structure and an elastic buffer layer is provided on its upper surface.

[0049] During operation, the moving roller 6252 drives the needle assembly 6253 to secure the end of the tape. After rotating and pulling out a set length, the tape cutter 624 extends horizontally to cut the tape. The moving roller 6252 carries the tape to the corresponding position on the mesh line, and the pressing plate 6262 moves upward to press the tape tightly onto the mesh line, completing the fixing of the wire end or the finishing of the tail end.

[0050] As a preferred option, such as Figure 1 As shown, it also includes an automatic roll changing and unloading device 7. The automatic roll changing and unloading device 7 includes a material picking robot 71, a storage box for storing spare second take-up rolls, a finished product output track 73, a roll diameter and thickness detection unit 74, and temporary storage racks located at both ends of the finished product output track 73. After the material picking robot 71 removes the second take-up roll, it places it on the finished product output track 73 and works with the roll diameter and thickness detection unit 74 to complete the detection. If the thickness reaches the specified value range, it is unloaded to one set of temporary storage racks, otherwise it is unloaded to another temporary storage rack, so as to achieve the effect of automatically completing full roll unloading, detection and sorting, and empty roll replacement.

[0051] Preferably, the device also includes a die head coaxiality adjustment mechanism, which includes a die core adjusting fastener disposed at the extrusion die head of the extrusion mechanism for adjusting the coaxiality of the extrusion die core online.

[0052] It should be noted that the extrusion mechanism is a screw extruder, and its extrusion die head is provided with a die head coaxiality adjustment mechanism. The die head coaxiality adjustment mechanism includes multiple sets of circumferentially arranged die core adjustment fasteners. By adjusting the feed amount of the fasteners, the radial position of the die core can be adjusted online, thereby correcting the coaxiality of the extruded wire.

[0053] Example 2 like Figure 1 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: A coaxiality-controlled extrusion production process for network cables, implemented using the aforementioned high-speed shielded network cable extrusion coaxiality-adjustment equipment, includes the following steps: S1. Extrusion and shaping: The die head of the extrusion mechanism extrudes the wire 100 covered with an insulation layer. After being cooled and shaped by the cooling and shaping mechanism 2, it is conveyed to the coaxiality online detection mechanism 3 for real-time detection. S2. Coaxiality Detection: The online coaxiality detection mechanism 3 performs real-time online detection of the coaxiality between the wire core and the insulation layer of the network cable. If the coaxiality deviation is within the preset threshold, it is judged as a qualified product and directly conveyed to the finished product winding device 6 to complete the winding. If the coaxiality deviation exceeds the preset threshold, it is judged as a non-qualified product, the system triggers the waste recycling process, and executes step S3. S3. Separation and Recycling of Non-conforming Products: The traction device 4 clamps and conveys the non-conforming section of the wire, and the transfer and cutting unit 51 cuts the non-conforming section of the wire and lifts it for transfer; during the transfer process, the insulation layer peeling and sorting unit 52 peels the insulation layer from the wire core, and the classification and collection unit 53 classifies and collects the peeled wire core and insulation layer separately; at the same time, the extrusion mechanism adjusts the position of the die core online and corrects the coaxiality through the die head coaxiality adjustment mechanism. Furthermore, when the traction device 4 is working, the circulating traction chain drives the clamping unit 411 to rotate in a cycle. When the clamping unit 411 passes through the clamping section of the guide cam rail 42, the clamping jaws close to clamp both sides of the mesh, and the material is driven forward at a uniform speed by a stable clamping force. When it passes through the release section, the jaws open to complete one conveying cycle.

[0054] Furthermore, the lifting pressure roller presses down to grip the end of the wire, and the connecting rod rotates to cause the lifting mounting frame to flip upward, pulling the unqualified wire away from the normal channel and sending it into the insulation peeling and sorting unit 52. After the wire enters the receiving channel, the electric clamping roller group clamps and conveys it, and the straight cutting blade cuts the insulation layer axially. Then the wire reaches the rubbing and peeling station, the lifting frame 5222 moves down, the elastic lever 5222 inserts into the cut, and the rubbing clamp 5223 rubs back and forth to completely peel the insulation layer from the wire core. The peeled wire core is clamped and wound by the wire core winding assembly 531, and the insulation layer falls into the guide frame and slides into the receiving box. When the subsequent wire is detected to be qualified, the cutting blade cuts and separates the unqualified tail end again. After all the unqualified sections are peeled off and collected, the flipping and lifting mechanism 514 resets, and the qualified wire returns to the normal channel.

[0055] S4. Qualified Continuous Production: When the online coaxiality detection mechanism 3 detects qualified products again, the transfer and cutting unit 51 cuts and separates the unqualified section from the qualified section. The unqualified section is continuously conveyed and collected. The qualified product is conveyed to the finished product winding device 6 by the traction device 4. The tail end continuation unit 62 fixes the starting end of the qualified wire onto the new winding roller of the winding unit 61, and resumes normal winding, realizing continuous non-stop production. Furthermore, after being guided by the second guide seat, the qualified wire is wound onto the second take-up roller and continuously wound by the take-up unit. When the qualified wire ends after rejecting defective products need to be spliced, the end splicing unit is activated: the needle assembly extends and secures the end of the tape, the moving roller rotates to pull out a fixed length of tape and cuts it; the moving roller feeds the tape to the end of the wire, and the pressing and lifting mechanism moves upward to press and stick the tape onto the wire, fixing the wire end on the take-up roller, thus completing the splicing. When the roll is full, the same process is used to stick the tape to the end of the wire, completing the end winding and preventing unraveling.

[0056] S5. Rewinding and finishing: When the qualified wire mesh is wound to the set diameter, the end-connecting unit 62 cuts tape to a fixed length and sticks it to the end of the wire mesh to complete the winding and fixing of the wire mesh. The automatic roll changing and unloading device 7 completes the unloading of the finished product and the replacement of the empty roller.

[0057] Furthermore, after winding is completed, the robotic arm removes the full-wound take-up roll and places it on the finished product output track; the roll diameter and thickness detection unit detects the finished roll diameter, and qualified and unqualified products are respectively transported to two sets of temporary storage racks. At the same time, the robotic arm takes an empty take-up roll from the storage box and installs it on the first mounting shaft to complete the roll change, and the production line continues to operate.
