Description

Technical Field

[0001] This invention belongs to the field of cable production technology, specifically referring to a compression winding device for cable production. Background Technology

[0002] As a critical infrastructure in modern industry, energy transmission, and information communication, the final winding process of cables is of paramount importance for ensuring finished cable quality, optimizing storage space, facilitating transportation, and subsequent laying and use. On the cable production line, continuously produced cables need to be neatly and compactly wound onto standard I-beam reels to form orderly cable spools. To achieve high-density, high-stability winding and prevent loosening, misalignment, collapse, or bulging of the cables on the reel due to vibration or tension changes, the industry practice is to apply a continuous radial pressure to the cable layers being wound during the winding process. This pressure operation is typically achieved through a pressure roller device that rises synchronously with the reel diameter. This roller is in close contact with the outermost cable layer, rolling and pressing it during winding to eliminate inherent gaps between the cables.

[0003] Currently, existing technologies typically employ pneumatic levers, hydraulic levers, or elastic elements (such as strong springs) to provide clamping force, applying a preset, essentially constant total pressure to the pressure roller. However, such clamping devices based on a constant total pressure design face a difficult-to-overcome technical bottleneck in practical applications. When one layer of cable is wound and the next layer begins, in the initial stage of layer switching, the effective contact surface of the pressure roller only contacts one cable. At this time, almost all the total pressure provided by the entire actuation mechanism is concentrated on this single cable, resulting in an instantaneously excessive pressure per unit length of cable. This overpressure state can easily cause irreversible physical damage to the cable's insulation or outer sheath, and may even affect the structural stability of the internal cable core. Conversely, when the layer of cable is about to be fully wound, the effective contact surface of the pressure roller contacts multiple cables simultaneously. At this point, the originally constant total pressure is distributed to all the contacting cables, and the effective clamping force distributed to each cable becomes smaller, which may result in a serious lack of clamping effect and an inability to effectively eliminate the gaps between the cables. This overpressure and underpressure are inherently contradictory to the constant total pressure, which restricts the cable winding quality. Summary of the Invention

[0004] To address the above issues, this invention provides a clamping winding device for cable production. A shaped cam disc, rotating synchronously with the I-beam reel, drives a lever mechanism to apply a periodically varying clamping force to the pressure roller. This clamping force is proportional to the number of cables wound in the same layer and abruptly changes from its maximum value to its minimum value at the moment of layer change. This effectively avoids the problems of over-pressure damaging the cable at the beginning and under-pressure loosening the reel at the end, significantly improving the quality of cable winding.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a compression winding device for cable production, including a winding machine body. The winding machine body includes a base plate, a frame disposed on the base plate, a clamping and winding assembly disposed on the frame, an I-beam reel clamped by the clamping and winding assembly, a guide assembly disposed above the I-beam reel, and a drive assembly for driving the I-beam reel to rotate and wind.

[0006] Furthermore, it also includes a translation mechanism on the base plate, a clamping mechanism fixed on the translation mechanism for horizontally clamping the cable in the I-beam reel, a lever force transmission mechanism connected to the clamping mechanism, a cyclic gradual pressure application mechanism for applying periodic gradual pressure to the lever force transmission mechanism, and a pair of distance sensors located on the outer side of the end of the horizontal reciprocating stroke of the guide assembly.

[0007] Furthermore, the translation mechanism includes a frame that can move on the base plate.

[0008] Furthermore, the clamping mechanism includes a bracket fixed to the frame and a pressure roller located on one side of the bracket for clamping the cable.

[0009] Furthermore, the lever force transmission mechanism is mounted on the support and includes a support rod fixed to the support and located below the pressure roller, and a rotating rod rotatably mounted on the support rod for transmitting pressure.

[0010] Furthermore, the cyclic gradual pressure application mechanism includes an irregularly shaped cam disk driven by a servo motor mounted on the vehicle frame, and the wheel surface of the irregularly shaped cam disk is connected to the lever force transmission mechanism.

[0011] Furthermore, the pressing mechanism also includes support plates symmetrically fixed on both sides of the bracket. Each support plate is horizontally arranged with two rows of rotatable guide wheels. A guide rod is horizontally slidably engaged between the two rows of guide wheels. The pressure roller is rotatably connected to the front end of the two guide rods and faces the side of the I-beam reel to achieve horizontal pressing.

[0012] Furthermore, a pressure groove is provided at the upper end of the rotating rod, and a pressure shaft is fixedly connected between the two guide rods. The pressure shaft is slidably fitted in the pressure groove. A positioning hole is provided on the rotating rod, and a positioning knob is threadedly connected to the support rod. When the rotating rod is in a vertical state, the end of the positioning knob can be inserted into the positioning hole to limit the rotation rod.

[0013] Furthermore, the cyclic gradual pressure application mechanism is located below the support rod and is located on the same side of the rotating rod together with the pressure roller. The cyclic gradual pressure application mechanism also includes a pair of first limiting posts horizontally fixed on the bracket and a first wheel seat horizontally sliding through the first limiting posts. The first wheel seat is rotatably provided with a first pressure roller facing one end of the rotating rod, and the first pressure roller abuts against the lower end of the rotating rod.

[0014] Furthermore, the cyclic gradual pressure application mechanism also includes a pair of second limiting posts on the side of the first wheel seat away from the rotating rod and a second wheel seat that slides horizontally through the second limiting posts. A second pressure wheel is rotatably provided at the end of the second wheel seat away from the first wheel seat. The second pressure wheel abuts against the wheel surface of the irregular cam disc. A compression spring is sleeved on the second limiting post, and the two ends of the compression spring abut against the first wheel seat and the second wheel seat respectively.

[0015] Furthermore, the radial length of the wheel surface of the irregular cam disk from its rotation axis gradually increases, and the end point and the start point of the gradient cam surface of the irregular cam disk are connected by a radially abrupt change surface.

[0016] Furthermore, the translation mechanism also includes a ball screw assembly located below the frame, a track groove is provided on the base plate, a wheel is provided at the bottom of the frame, the wheel is engaged in the track groove, and the ball screw assembly is used to drive the frame to move along the length direction of the track groove.

[0017] Furthermore, the servo motor drives the irregular cam disk to rotate one revolution, which is synchronized with the guide component guiding the cable to cover one layer of the I-beam reel. When the guide component moves to the end of the one-way stroke, the distance sensor on this side detects the position of the guide component and sends a signal to control the ball screw assembly to drive the frame away from the I-beam reel by a distance equal to the diameter of a cable. At the same time, the second pressure roller contacts the abrupt change surface of the irregular cam disk.

[0018] Furthermore, during the contact process between the gradient cam surface of the irregular cam disk and the second pressure roller, the elastic force generated by the compression spring has a minimum value corresponding to the clamping force applied to a single cable, and a maximum value corresponding to the clamping force applied to multiple cables covering a layer. The ratio of the maximum value to the minimum value is equal to the total number of cables in each layer.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows: (1) By setting up a cyclic gradual pressure mechanism, the present invention utilizes a shaped cam disk driven by a servo motor. Its gradually increasing radial length, in conjunction with a compression spring, can generate a periodically varying clamping force that is proportional to the number of cables wound in the same layer. This clamping force is at its minimum when acting on a single cable at the initial stage of layer change, effectively avoiding the problem of overpressure damage to the cable caused by pressure concentration. When the layer is about to be fully wound, the clamping force reaches its maximum value and is distributed to multiple cables in the row, ensuring sufficient clamping effect. This fundamentally solves the inherent contradiction of overpressure at the beginning and underpressure at the end caused by constant total pressure in the prior art, and significantly improves the density of cable winding and the quality of finished products.

[0020] (2) The present invention achieves a high degree of automation and precise synchronization of clamping force regulation and layer changing action. By synchronizing the rotation speed of the servo motor with the reciprocating stroke time of the guide component, and using the distance sensor at the end of the stroke to send a trigger signal, the device can control the ball screw assembly to drive the entire clamping device to retreat a distance of one cable diameter at the moment when a layer of cable is laid, so as to reserve space for the new layer to be wound. At the same time, the abrupt change surface on the irregular cam plate is used to make the clamping force switch from the maximum value to the minimum value instantly to match the initial winding state of the new layer. The whole process does not require manual intervention, the control is precise, and it ensures the smoothness of the transition between layers and the continuity of the clamping force application. It has a high degree of automation and reliable operation. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10As shown, the present invention proposes a compression winding device for cable production, including a winding machine body 1. The winding machine body 1 is the basic platform for realizing cable winding. Its structure can adopt existing mature technology, and typically includes a base plate 11 for supporting the entire device, a frame 12 built on the base plate 11, a clamping and winding assembly 13 mounted on the frame 12 for clamping and driving the I-beam reel 14 to rotate, and a drive assembly 16 for driving the I-beam reel 14 to rotate and wind. Above the I-beam reel 14, there is a guide assembly 15, which can move horizontally reciprocally during the winding process, thereby guiding the cable to be arranged layer by layer and neatly within the winding area of ​​the I-beam reel 14.

[0036] The key improvement of this invention is that the device also includes a set of cooperating clamping and control systems, which include: a translation mechanism 5 disposed on the base plate 11; a clamping mechanism 2 fixed on the translation mechanism 5 for applying a horizontal clamping force to the cable being wound in the I-beam reel 14; a lever transmission mechanism 3 connected to the clamping mechanism 2 for transmitting the clamping force; a cyclic gradual pressure application mechanism 4 for providing periodically gradual pressure to the lever transmission mechanism 3; and a pair of distance sensors 6 disposed on the outer sides of the two ends of the horizontal reciprocating stroke of the guide assembly 15 for detecting the position of the guide assembly 15.

[0037] Specifically, the translation mechanism 5 includes a frame 51 that can move on a base plate 11. A guide rail groove 54 is formed on the base plate 11 in a direction perpendicular to the axis of the I-beam reel 14. The bottom of the frame 51 is provided with wheels 53 that can cooperate with the guide rail groove 54. A ball screw assembly 52 is also provided below the frame 51. The nut seat of the ball screw assembly 52 is fixedly connected to the frame 51. Its screw is driven by an independent motor. By precisely controlling the rotation of the ball screw assembly 52, the entire frame 51 and all the mechanisms fixed on it can be driven to translate precisely along the length direction of the guide rail groove 54.

[0038] The clamping mechanism 2 is mounted on the frame 51. Its main body is a bracket 21. Support plates 22 are symmetrically fixed on both sides of the bracket 21. Each support plate 22 has two rows of freely rotatable guide wheels 23 evenly distributed horizontally. Two parallel guide rods 24 are horizontally engaged and slidably disposed between the upper and lower rows of guide wheels 23. This design ensures that the guide rods 24 can move horizontally with minimal frictional resistance. A pressure roller 25 with a width matching the inner width of the I-beam reel 14 is rotatably connected to the front end of the two guide rods 24 and faces the winding area of ​​the I-beam reel 14. The connection position between the guide rods 24 and the pressure roller 25 is located in the non-side area of ​​the pressure roller 25, so that the two ends of the pressure roller 25 can penetrate into the vicinity of the side wall of the I-beam reel 14 without obstruction, achieving full coverage clamping of the entire layer of cable. The gap on the pressure roller 25 for accommodating the guide rods 24 can be set very small and will not affect the clamping of the cable.

[0039] The lever transmission mechanism 3 is mounted on the support 21 and is used to transmit the force generated by the cyclic gradual pressure application mechanism 4 to the pressure roller 25. The mechanism includes a support rod 31 as a fulcrum, which is horizontally fixed on the support 21 and located below the pressure roller 25. A rotating rod 32 is rotatably mounted on the support rod 31 through a bearing. The upper end of the rotating rod 32 has a pressure groove 33. A pressure shaft 36 is fixedly connected between two guide rods 24. The pressure shaft 36 is slidably fitted in the pressure groove 33. When the rotating rod 32 swings around the support rod 31, the pressure groove 33 at its upper end will push the pressure shaft 36, thereby causing the guide rods 24 and the pressure roller 25 to produce horizontal displacement. For easy initial setup, a positioning knob 34 is threaded onto the support rod 31. When the rotating rod 32 is in a vertical state, the positioning hole 35 on the rotating rod 32 is aligned with the positioning knob 34. At this time, the positioning knob 34 is screwed in, and its end can be inserted into the positioning hole 35, thereby locking the rotating rod 32 and preventing it from being affected by external forces.

[0040] The cyclic gradual pressure mechanism 4 is located below the support rod 31 and on the same side of the rotating rod 32 as the pressure roller 25. The mechanism includes an irregularly shaped cam disk 48 driven by a servo motor 49. The profile of the irregularly shaped cam disk 48 is precisely designed, and the radial length of its wheel surface from its rotation axis increases gradually, forming a gradual cam surface similar to an Archimedean spiral. The end point (at the maximum radius) and the beginning point (at the minimum radius) of the gradual cam surface are connected by a radially abrupt change surface.

[0041] To convert the rotational motion of the irregular cam disk 48 into linear, gradual pressure, the mechanism also includes a force transmission assembly. Specifically, a pair of first limiting posts 41 are horizontally fixed on the bracket 21, and a first wheel seat 42 is horizontally slidably mounted on the first limiting posts 41. A first pressure roller 43 is rotatably mounted on one end of the first wheel seat 42 facing the rotating rod 32. The wheel surface of the first pressure roller 43 abuts against the lower end of the rotating rod 32. On the side of the first wheel seat 42 away from the rotating rod 32, a pair of second limiting posts 44 are provided, and a second wheel seat 45 is horizontally slidably mounted on the second limiting posts 44. A second pressure roller 46 is rotatably mounted on the end of the second wheel seat 45 away from the first wheel seat 42. The wheel surface of the second pressure roller 46 rolls in contact with the wheel surface of the irregular cam disk 48. Between the first wheel seat 42 and the second wheel seat 45, a compression spring 47 sleeved on the second limiting post 44 always applies a spring force to both.

[0042] The specific work process is as follows: Initial setup: First, install an empty H-beam reel 14 onto the clamping and winding assembly 13 using a forklift or other tools. At the same time, screw in the positioning knob 34 so that it is inserted into the positioning hole 35 on the rotating rod 32, locking the rotating rod 32 in the vertical initial position. Start the ball screw assembly 52 to drive the frame 51 forward, so that the surface of the pressure roller 25 is close to the winding mandrel of the H-beam reel 14, leaving a gap of one cable diameter. Fix the end of the cable to be wound onto the mandrel.

[0043] Pressure Preset and Release: Start the servo motor 49 to drive the irregular cam disk 48 to rotate to a specific initial position. This position ensures that the second pressure roller 46 passes through the abrupt change surface of the irregular cam disk 48 and reaches the minimum radius of the disk. At this position, the compression of the spring 47 is minimal, and its stored elastic energy is also minimal. Then, turn out the positioning knob 34 to release the lock on the rotating rod 32. At this time, the minimum elastic force of the spring 47 is transmitted to the lower end of the rotating rod 32 through the second wheel seat 45, the first wheel seat 42, and the first pressure roller 43. Through the pressure groove 33 and the pressure shaft 36 at the upper end of the rotating rod 32, it is finally applied to the first cable to be wound by the pressure roller 25. This initial pressure is precisely designed to be the most suitable clamping force for a single cable.

[0044] Synchronous winding and gradual pressure increase: Start the drive assembly 16 and guide assembly 15, the I-beam reel 14 begins to rotate and wind, the guide assembly 15 moves from one end to the other, and the guide cable is tightly arranged round by round. The key is that the servo motor 49 also starts at the same time. The angular velocity of the shaped cam disk 48 is precisely matched with the lateral movement speed of the guide assembly 15, ensuring that the time for the shaped cam disk 48 to rotate one revolution is exactly equal to the time for the guide assembly 15 to guide the cable to fill one layer of the I-beam reel 14. As the shaped cam disk 48 rotates, its gradual cam surface continuously pushes the second pressure roller 46, so that the compression of the compression spring 47 increases linearly, and the clamping force also increases linearly. This gradually increasing total pressure is evenly distributed on the multiple wound cables.

[0045] Layer Change and Pressure Sudden Change: When the guide component 15 moves to the end of the one-way stroke, it means that the cable layer has been fully laid. At this time, the distance sensor 6 on this side will detect the position of the guide component 15 and immediately send a signal. After receiving the signal, the control system will control the drive motor of the ball screw assembly 52 to drive the frame 51 to move backward by a precise distance equal to the diameter of the cable, providing space for the winding of the next layer of cable. At this time, the irregular cam disk 48 has also rotated a full revolution. The second pressure roller 46 on its wheel surface just passes the point of maximum radius and instantly falls back to the starting point of minimum radius along the sudden change surface. This causes the pressure of the compression spring 47 to instantly change from the maximum value to the minimum value, thus changing to the pressure suitable for the first cable of the new winding layer. This process repeats itself. With the reciprocating motion of the guide component 15, the clamping force undergoes a gradual change in each layer and a sudden change at each layer change, perfectly matching the actual pressure requirements in the winding process.

[0046] It should be noted that by precisely designing the contour curve of the irregular cam disc 48 and the elastic coefficient of the compression spring 47, the ratio of the maximum elastic force to the minimum elastic force generated by the compression spring 47 can be precisely equal to the total number of cables that each layer of the I-beam reel 14 can accommodate. This ensures that the average pressure distributed on each cable remains near a constant value throughout the winding process.
