Description

Technical Field

[0001] This invention relates to the field of data cable shielding layer processing technology, specifically to a continuous metal rolling composite device for data cable shielding layers. Background Technology

[0002] The data cable shielding layer is the core protective structure of the data cable. It is mainly made of ultra-thin metal strip through continuous rolling composite process. Its function is to shield electromagnetic interference and ensure the stability of data cable signal transmission. It is widely used in consumer electronics, communication equipment, smart terminals and other fields. The continuous rolling composite process of the shielding layer aims to tightly roll various metal strips to form a uniform, dense shielding layer with excellent electromagnetic shielding performance.

[0003] In actual production, to adapt to the processing requirements of data cable shielding strips of different specifications and thicknesses, it is necessary to frequently adjust the spacing of the work rolls and change the opening of the rolling roll gap to control the rolling thickness and composite accuracy of the strip. Conventional rolling equipment's feeding clamping and centering structure is mostly a fixed-opening guide plate or a spring-preloaded pressure roll. The clamping spacing and clamping force cannot adaptively adjust with changes in the opening of the rolling roll gap. It can only adapt to strip limiting operations under a single fixed roll gap condition and needs to be adjusted separately. Its opening and clamping force need to be manually preset. Unable to sense and follow the position changes of the work rolls, thick strips have good rigidity, but their bending resistance in the width direction is still limited. Furthermore, the feed speed fluctuates greatly under a large roll gap, requiring a large lateral clamping force to maintain centering stability. Thin strips, on the other hand, have extremely poor rigidity and are easily damaged by clamping. If the same clamping force is applied, it will cause indentations and burrs on the strip edges at best, and may even break the strip directly at worst. When the roll gap changes due to product specifications, the clamping state of the anti-deviation mechanism cannot be matched synchronously, making it difficult to meet the continuous rolling production needs of multi-specification, high-precision shielding strips. Summary of the Invention

[0004] The purpose of this invention is to provide a continuous rolling composite device for metal shielding layers of data lines, so as to solve the technical problem that the centering structure in the prior art is difficult to meet the rolling requirements of composite strips of different thicknesses.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A continuous rolling composite device for data cable shielding layers includes a frame and a pair of support rolls and work rolls arranged vertically within the frame. The pair of work rolls are located between the pair of support rolls and cooperate to form a rolling gap. The device also includes a bracket fixed to the feed end of the frame. Inside the bracket are a pair of clamping rolls respectively connected to the corresponding work rolls. An anti-deviation centering mechanism is elastically mounted on both sides of the bracket. Adjustment kits are rotatably fitted at both ends of the clamping roll shafts. The anti-deviation centering mechanism is inserted into the adjustment kits. A toothed ring is fixedly fitted outside the adjustment kit. A transmission rack that meshes with the toothed ring is vertically fixed to one side of the frame. When the work rolls drive the clamping rolls to rise and fall, reducing the rolling gap opening, the adjustment kit rotates and drives the anti-deviation centering mechanisms on both sides to open synchronously, adjusting the lateral clamping force on the strip according to the change in the rolling gap opening.

[0006] Preferably, a connecting rod is installed between the roller shaft of the clamping roller and the bearing seat of the working roller. One end of the connecting rod is rotatably connected to the end of the roller shaft of the clamping roller, and the other end is fixedly connected to the bearing seat of the working roller. A slider is fixedly connected to the inner side of the connecting rod, and a groove matching the slider is vertically opened on the frame.

[0007] Preferably, the adjustment kit includes a sleeve fitted around the outside of the clamping roller shaft, one end of which is fixedly connected to a guide ring and the other end is fixedly connected to a limit ring, and the clamping roller shaft is provided with a limit groove that matches the limit ring.

[0008] Preferably, the outer circumferential surface of the guide ring is provided with a spiral guide groove, and the spiral guide grooves on the guide rings of the upper and lower clamping rollers on the same side have the same spiral direction, while the spiral guide grooves on the guide rings on both sides have opposite spiral directions.

[0009] Preferably, the anti-deviation centering mechanism includes a centering plate and a pressure plate respectively installed on the inner and outer sides of the frame. One side of the pressure plate passes through the frame and elastically abuts against the centering plate. A plug rod inserted into the spiral guide groove is fixedly connected to the pressure plate. A pair of support rods are fixedly connected to the side of the centering plate facing away from the strip. The end of the support rod passes through the bracket and is fitted with an end cap. A return spring is sleeved on the support rod. The two ends of the return spring abut against the bracket and the end cap respectively.

[0010] Preferably, fasteners are installed through the connecting rod and the slider, and the ends of the fasteners abut against the inner wall of the groove.

[0011] Preferably, the bracket has a pair of horizontal bars fixedly connected inside, and the two centering plates are located between the pair of horizontal bars. The upper and lower ends of the centering plates are in sliding contact with the pair of horizontal bars, respectively.

[0012] Preferably, one side of the pressure plate is symmetrically and slidably mounted with elastic abutments that contact a pair of clamping rollers, one end of the elastic abutment is elastically inserted with a top rod, and one side of the crossbar is fitted with a brake rack that cooperates with the top rod.

[0013] Preferably, a pair of stop bars are hinged to the inner side of the centering plate, the pair of stop bars are closed to form a flared mouth, and a tensioning rod is hinged between the stop bars and the elastic abutment plate.

[0014] Preferably, a pair of bushings are installed on the roller shaft of the clamping roller, and through grooves are vertically opened on the inner walls of both sides of the bracket, with the bushings embedded in the through grooves and slidingly engaging with them.

[0015] In the above technical solution, the lifting motion of the work roll is directly converted into the clamping action of the anti-deviation mechanism through the meshing transmission of the gear ring and the transmission rack, and the insertion and cooperation of the adjusting kit and the anti-deviation centering mechanism. When the rolling roll gap increases, the anti-deviation clamping force automatically increases synchronously, and the thick strip automatically obtains stronger lateral restraint force to prevent it from deviating due to feed fluctuations under a larger roll gap. When the rolling roll gap decreases, the clamping force automatically weakens, and the thin strip automatically obtains a gentle clamping force, eliminating problems such as pinching, indentation, and strip breakage. Regardless of the thickness specification being switched, the clamping force remains constant. Within the optimal range, the entire process requires no manual intervention, responding promptly and precisely, greatly improving the rolling stability of thin strip. Furthermore, the lateral constraint of the anti-deviation centering mechanism can always keep it in the ideal center position, completely solving the problems of serpentine deviation, edge waves, and strip breakage during high-speed rolling. It significantly improves the thickness uniformity and surface quality of the data line shielding layer. When adjusting the roll gap, operators no longer need to stop the machine separately to adjust the anti-deviation structure, which not only reduces the number of operation steps but also eliminates human adjustment errors, thereby greatly improving the efficiency of continuous rolling and product yield.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0022] Please see Figures 1-8This invention provides a continuous rolling composite device for data cable shielding layers, comprising a frame 1 and a pair of support rollers 2 and work rollers 3 arranged vertically within the frame 1. The pair of work rollers 3 are located between the pair of support rollers 2 and cooperate to form a rolling gap. The device also includes a bracket 5, which is fixed to the feed end of the frame 1. Inside the bracket 5, a pair of clamping rollers 6 are installed, which are respectively connected to the corresponding work rollers 3. An anti-deviation centering mechanism 7 is elastically installed on both sides of the bracket 5. Adjustment kits 8 are rotatably sleeved at both ends of the roller shaft of the clamping rollers 6. The anti-deviation centering mechanism 7 is inserted into the adjustment kit 8. A toothed ring 4 is fixedly sleeved on the outside of the adjustment kit 8. A transmission rack 101 that meshes with the toothed ring 4 is vertically fixedly connected to one side of the frame 1. When the work rollers 3 drive the clamping rollers 6 to rise and fall, making the rolling gap opening smaller, the adjustment kit 8 rotates and drives the anti-deviation centering mechanisms 7 on both sides to open synchronously, so as to adjust the lateral clamping force on the strip according to the change of the rolling gap opening.

[0023] Specifically, the frame 1 is an open rolling mill frame 1. The upper and lower support rolls 2 are both raised and lowered via independent hydraulic drive mechanisms. These hydraulic drive mechanisms are fixedly connected to the bearing seats of the upper and lower support rolls 2, respectively, and are used to drive the upper and lower support rolls 2 vertically up and down within the frame 1 to achieve precise adjustment of the rolling gap opening. A pair of work rolls 3 are located between the upper and lower support rolls 2, respectively, and are supported and have the rolling force transmitted by the upper and lower support rolls 2. The upper and lower work rolls 3 cooperate to form a rolling gap through which the metal strip passes. When the hydraulic drive mechanism drives the upper and lower support rolls 2 to rise and fall, the upper and lower support rolls 2 respectively drive the upper and lower work rolls 3 to move closer or further apart, thereby adjusting the rolling gap opening to accommodate metal strips of different thicknesses used for data cable shielding layers. To meet rolling requirements, within the support 5 at the feed end of the frame 1, the gap between the two clamping rollers 6 is larger than the rolling roll gap. The ends of the clamping rollers 6 extend outwards, and each clamping roller 6's roller shaft is connected to the bearing seat of the corresponding work roller 3. Therefore, when the upper and lower support rollers 2 are hydraulically driven to rise and fall, the work roller 3 synchronously drives the corresponding clamping roller 6 to move up and down the same distance within the support 5. Before equipment startup or during strip feeding, the upper hydraulic cylinder drives the upper support roller 2 to rise to a high position, and the lower hydraulic cylinder drives the lower support roller 2 to fall to a low position. At this time, the rolling roll gap is at its maximum opening, suitable for thicker metal strips. The work roller 3 is at the position corresponding to the larger roll gap, and the clamping roller 6 is subsequently at the corresponding position within the support 5. The toothed ring 4 operates in the transmission gear... At the corresponding end of strip 101, the adjusting kit 8 is at its initial angle, and the anti-deviation centering mechanism 7 is in a slightly open or semi-tightened state under the preload of the return spring 706, waiting for the strip to enter. When producing thicker data cable shielding layer metal strip, the upper support roller 2 and the support roller 2 move towards each other under their respective hydraulic drives, driving the work roller 3 to move synchronously. The work roller 3 then drives the clamping roller 6 to move synchronously up and down within the bracket 5 through the connecting structure. The displacement of the clamping roller 6 causes the toothed rings 4 at both ends to roll along the fixed transmission rack 101. The rotation of the toothed rings 4 drives the adjusting kit 8 fixed to it to rotate synchronously. The adjusting kit 8 then drives the anti-deviation centering mechanism 7 to move inward, pressing against the two sides of the metal strip with a greater clamping force. Thick strip is more likely to be produced under greater rolling force. When significant lateral stress is generated, the automatically enhanced clamping force effectively resists the lateral movement of the strip, preventing it from serpentine deviation during feed fluctuations and avoiding wavy edges. When switching from thick to thin strip production, the hydraulically driven upper support roller 2 moves downward and the hydraulically driven lower support roller 2 moves upward, bringing the upper work roller 3 and the work roller 3 closer together. This reduces the rolling roll gap, and the displacement of the work roller 3 causes the clamping roller 6 to move in the opposite direction. The toothed ring 4 rolls in the opposite direction along the transmission rack 101 and reverses. The adjusting kit 8 rotates in the opposite direction, causing the anti-deviation centering mechanism 7 to move outward, reducing the clamping force on the strip edge. Thin strip requires less rolling force; excessive clamping force can easily cause indentations, surface scratches, or even tensile fractures in extremely thin strip.At this point, the gentle and moderate clamping force ensures that the strip remains centered without causing mechanical damage, thus guaranteeing the rolling stability and surface finish of the ultra-thin strip.

[0024] Compared with the prior art, the embodiments of the present invention directly convert the lifting motion of the work roll 3 into the clamping action of the anti-deviation mechanism through the meshing transmission of the gear ring 4 and the transmission rack 101, and the insertion and cooperation of the adjusting kit 8 and the anti-deviation centering mechanism 7. When the rolling roll gap increases, the anti-deviation clamping force automatically increases synchronously, and the thick strip automatically obtains stronger lateral restraint force to prevent it from deviating in the feeding fluctuations under a larger roll gap. When the rolling roll gap decreases, the clamping force automatically weakens, and the thin strip automatically obtains a gentle clamping force, eliminating the problems of pinching, indentation and strip breakage. Regardless of the thickness specification being switched, the clamping... The force is always within the optimal range, and the entire process requires no manual intervention. The response is timely and precise, which greatly improves the rolling stability of ultra-thin strip. Furthermore, the lateral constraint of the anti-deviation centering mechanism 7 can always keep it in the ideal center position, completely solving the problems of serpentine deviation, edge waves, and strip breakage in the high-speed rolling process. It significantly improves the thickness uniformity and surface quality of the data line shielding layer. When adjusting the roll gap, the operator no longer needs to stop the machine separately to adjust the anti-deviation structure, which not only reduces the operation steps but also eliminates human adjustment errors, thereby greatly improving the efficiency of continuous rolling and product yield.

[0025] In a further embodiment of the present invention, a connecting rod 9 is installed between the roller shaft of the clamping roller 6 and the bearing seat of the working roller 3. One end of the connecting rod 9 is rotatably connected to the end of the roller shaft of the clamping roller 6, and the other end is fixedly connected to the bearing seat of the working roller 3. A slider 901 is fixedly connected to the inner side of the connecting rod 9. A groove 102 matching the slider 901 is vertically opened on the frame 1. Specifically, the connecting rod 9 is a rigid metal rod, which is rotatably connected to the end of the roller shaft of the clamping roller 6 through a bearing, allowing the clamping roller 6 to rotate. Any vertical displacement of the working roller 3 under the drive of the support roller 2 will be transmitted to the clamping roller 6 through the connecting rod 9. The slider 901 is embedded in the groove 102 and forms a sliding fit, which guides and limits the lifting and lowering movement of the connecting rod 9 and the clamping roller 6, preventing the clamping roller 6 from tilting when under force.

[0026] In a further embodiment of the present invention, the adjusting kit 8 includes a sleeve 801 sleeved around the roller shaft of the clamping roller 6, a toothed ring 4 fixedly sleeved around the sleeve 801, a guide ring 802 fixedly connected to one end of the sleeve 801, and a limit ring 803 fixedly connected to the other end. A limit groove 602 matching the limit ring 803 is provided on the roller shaft of the clamping roller 6. Specifically, the limit ring 803 is embedded in the limit groove 602, which restricts the degree of freedom of movement of the adjusting kit 8 along the axial direction of the roller shaft, and allows the adjusting kit 8 to rise and fall together with the clamping roller 6, and also to rotate around the roller shaft. The guide ring 802 is used to guide and traction the anti-deviation centering mechanism 7 during rotation. The toothed ring 4 outside the sleeve 801 meshes with the transmission rack 101 on the frame 1, which not only ensures the smoothness of the clamping roller 6 when it rises and falls, but also ensures that the axial position of the guide ring 802 does not change.

[0027] In a further embodiment of the present invention, a spiral guide groove 804 is provided on the outer peripheral surface of the guide ring 802, and the spiral guide grooves 804 on the guide rings 802 of the upper and lower clamping rollers 6 on the same side have the same rotation direction, while the spiral guide grooves 804 on the guide rings 802 on both sides have opposite rotation directions. Specifically, the spiral guide groove 804 is arranged to rotate around the axis of the guide ring 802, and its function is to convert the rotational motion of the guide ring 802 into the linear motion of the anti-deviation centering mechanism 7. When the upper working roller 3 and the lower working roller 3 approach the rolled thin strip, the upper clamping roller 6 and the lower clamping roller 6 move in the same direction. Since the spiral grooves on the same side have the same rotation direction, the upper and lower guide rings 802 rotate in the same direction. Through subsequent insertion and cooperation, the anti-deviation centering mechanism 7 on the same side is synchronously driven to open outward, while the left and right sides rotate in opposite directions, which ensures that the anti-deviation centering mechanisms 7 on the left and right sides can synchronously and symmetrically perform the opening or tightening action, and avoid the strip being subjected to unilateral load.

[0028] In a further embodiment of the present invention, the anti-deviation centering mechanism 7 includes a centering plate 701 and a pressure plate 702 respectively installed on the inner and outer sides of the frame 1. The centering plate 701 is located on the inner side of the frame 1 and is used to directly constrain the edge of the strip. The pressure plate 702 is located on the outer side of the frame 1. One side of the pressure plate 702 penetrates the frame 1 and elastically abuts against the centering plate 701. An elastic gasket is installed at the abutting end of the pressure plate 702, and a plug rod 703 inserted into the spiral guide groove 804 is fixedly connected to the pressure plate 702. A pair of support rods 704 are fixedly connected to the side of the centering plate 701 facing away from the strip. The ends of the support rods 704 penetrate the bracket 5 and are equipped with end caps 705. A return spring 706 is sleeved on the support rods 704. The two ends of the return spring 706 abut against the bracket 5 and the end cap 705 respectively. Specifically, this elastic contact method allows the centering plate 701 to have a certain amount of buffer floating when impacted by the strip, avoiding damage to the strip from hard collisions. When the guide ring 802 rotates with the lifting and lowering of the clamping roller 6, the groove wall of the spiral guide groove 804 pushes or pulls the insertion rod 703, forcing the pressure plate 702 to move linearly in the horizontal direction, thereby driving the centering plate 701 to move synchronously. In the initial state, the return spring 706 always pulls the centering plate 701 outward through its elastic force. When the spiral guide groove 804 overcomes the spring force through the insertion rod 703 and applies pressure to the centering plate 701 towards the center of the strip, the return spring 706 is further compressed to store potential energy so as to provide a reset driving force for the centering plate 701 when the spiral guide groove 804 rotates in the opposite direction.

[0029] In a further embodiment of the present invention, a fastener 902 is installed through the connecting rod 9 and the slider 901. The end of the fastener 902 abuts against the inner wall of the slide groove 102. Specifically, after the clamping roller 6 is adjusted to the target height with the working roller 3, the operator or automated equipment tightens the fastener 902 so that its end abuts tightly against the inner wall of the slide groove 102, thereby locking the slider 901 and even the entire clamping roller 6 on the frame 1. When rolling strip of the same specification for a long time, the position of the clamping roller 6 will not drift slightly due to vibration or strip impact, ensuring the constant anti-deviation centering force.

[0030] In a further embodiment of the present invention, a pair of horizontal bars 501 are fixedly connected inside the bracket 5, and two centering plates 701 are located between the pair of horizontal bars 501. The upper and lower ends of the centering plates 701 are in sliding contact with the pair of horizontal bars 501 respectively. Specifically, the horizontal bars 501 not only bear the gravity load of the centering plates 701, but also strictly limit the centering plates 701 to slide back and forth in the horizontal direction, so as to prevent the centering plates 701 from warping or deflecting when subjected to force, and ensure that the clamping force is strictly applied to the edge of the strip in the transverse direction.

[0031] In a further embodiment of the present invention, an elastic abutment 707 is symmetrically slidably mounted on one side of the pressure plate 702, which contacts a pair of clamping rollers 6. The upper elastic abutment 707 rests above the upper clamping roller 6, and the lower elastic abutment 707 rests below the lower clamping roller 6. A receiving groove is vertically opened on one side of the pressure plate 702, and the elastic abutment 707 moves vertically within the receiving groove. A tension spring 711 is installed between one end of the elastic abutment 707 and the receiving groove, and the tension spring 711 keeps the elastic abutment 707 in constant contact with the corresponding clamping roller 6. The other end of the elastic abutment 707 is elastically inserted into... There is a push rod 708, the top of which has a symmetrical inclined surface. An elastic element is installed between the push rod 708 and the elastic abutment plate 707. A brake rack 503 is embedded on one side of the crossbar 501, which cooperates with the abutment end of the push rod 708. Specifically, when rolling thicker metal strip, the rolling roll gap is larger. The anti-deviation centering mechanism 7 tightens inward to provide strong lateral restraint. Due to the large rolling force and strong lateral stress of the thick strip, it will exert a significant reverse impact force on the centering plate 701, attempting to push the anti-deviation centering mechanism 7 outward. At the same time, due to the larger roll gap, the upper... When the clamping roller 6 is in a high position, the upper elastic abutment plate 707 is also in a high position. When the lower clamping roller 6 is in a low position, the lower elastic abutment plate 707 is also in a low position. The end of the elastic abutment plate 707 will exert a greater vertical force on the push rod 708. Under this vertical pressure, the abutting end of the push rod 708 is pressed into the tooth groove of the brake rack 503. A huge normal pressure and friction are generated between the tooth surface and the inclined surface of the push rod 708, ensuring that even if the strip experiences violent jumping or lateral impact during the rolling process, the anti-deviation centering mechanism 7 will not accidentally loosen or... During the retraction, a constant clamping force is maintained. When rolling extremely thin metal strips, the opening of the rolling roll gap is small, and the anti-deviation centering mechanism 7 opens outward, resulting in a gentle clamping force. At this time, the lateral thrust generated by the thin strip is minimal, and the reverse impact force on the center plate 701 is also very weak. The vertical force exerted by the elastic abutment plate 707 on the push rod 708 is correspondingly reduced. Under a small vertical pressure, the wedging force between the push rod 708 and the tooth surface of the brake rack 503 is also greatly reduced, so that the center plate 701 can adaptively fine-tune under the force of the return spring 706.

[0032] In a further embodiment of the present invention, a pair of stop bars 709 are hinged to the inner side of the middle plate 701. The pair of stop bars 709 converge to form a flared mouth, with the larger opening facing the feed end of the frame 1 and the smaller opening facing the rolling roll gap. A tension link 710 is hinged between the stop bars 709 and the elastic abutment plate 707. Specifically, when the two working rolls 3 approach each other, they will simultaneously drive the two clamping rolls 6 to approach each other, thereby reducing the force exerted by the clamping rolls 6 on the elastic abutment plate 707. The two elastic abutment plates 707 then move towards each other under the action of the tension spring 711. As the strip moves closer, the slight backsliding of the elastic stop plate 707 is transmitted through the traction link 710, driving the stop bar 709 to swing back axially inward around one end of the hinge. The tilt angle decreases, and the retracted stop bar 709 provides only very slight guidance correction, minimizing lateral interference to the edge of the thin strip and ensuring that the thin strip enters the rolling roll gap smoothly and without damage. The tilt angle of the stop bar 709 will adjust accordingly with the change of the roll gap, and the opening of the bell mouth will always maintain the best matching relationship with the current strip thickness specification, without any sudden jumps.

[0033] In a further embodiment of the present invention, a pair of bushings 603 are installed on the roller shaft of the clamping roller 6. A through groove 504 is vertically opened on the inner wall of both sides of the bracket 5. The bushings 603 are embedded in the through groove 504 and slide with it. Specifically, the groove wall of the through groove 504 plays a role in guiding the bushings 603 up and down and limiting them left and right, ensuring that the roller shaft of the clamping roller 6 always maintains strict parallelism and centering position during the lifting and lowering process with the working roller 3, and will not produce slight sway due to the rigid connection of the connecting rod 9, thereby ensuring the uniformity of the roller gap between the upper and lower clamping rollers 6 and the symmetry of the force on the anti-deviation centering mechanism 7.

[0034] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
