Description

Technical Field

[0001] This utility model relates to the field of wire and cable production technology, and in particular to a self-adjusting shock-absorbing meter-counting structure. Background Technology

[0002] Measuring cable length typically requires a meter-counting structure. For example, Chinese utility model patent CN203964892U discloses a thermal printing meter-counting device that uses a cylinder to regulate pressure, reducing cable deformation; and employs an encoder to achieve the meter-counting effect. However, in the high-speed cable production process described above, especially after wrapping or armoring and extruding with textured surfaces, the cable vibrates as it passes the meter-counting frame, generating thrust on both ends of the meter-counting wheel. This causes the meter-counting wheel to jump as it passes over the surface texture, affecting the meter-counting accuracy. Utility Model Content

[0003] To overcome at least one of the defects described in the prior art, this utility model provides a self-adjusting vibration-damping metering structure. This solves the problem of inaccurate metering caused by frequent adjustments to the metering structure pressure during wire and cable production, as well as by unevenness or significant vibration on the surface of the wires and cables.

[0004] The technical solution of this utility model is implemented as follows: A self-adjusting damping meter-counting structure includes a damping and buffering assembly, a damping hydraulic device, a meter-counting structure, a support frame, and a base. The meter-counting structure is positioned on top of the support frame; the base is positioned below the support frame and spaced apart from it; the damping hydraulic device is mounted on the base, and its output end is fixedly connected to the support frame; the damping and buffering assembly is positioned between the support frame and the base.

[0005] Based on the above technical solutions, preferably, the shock absorption and buffer assembly is a shock absorption spring, one end of the shock absorption spring is fixedly connected to the support frame, and the other end of the shock absorption spring is fixedly connected to the base.

[0006] Based on the above technical solutions, preferably, the system further includes a shock-absorbing sleeve and a damping sleeve, wherein the damping sleeve is sleeved inside the shock-absorbing buffer assembly and extends out of the outer bottom of the base; the shock-absorbing sleeve is fixedly disposed below the base, at least a portion of the damping sleeve is located inside the shock-absorbing sleeve, and the damping sleeve is capable of longitudinal movement relative to the shock-absorbing sleeve.

[0007] Based on the above technical solutions, preferably, two shock-absorbing hydraulic devices are provided and symmetrically distributed along the center of the base, and the shock-absorbing buffer assembly is located at the center point of the base.

[0008] Based on the above technical solutions, preferably, the shock-absorbing hydraulic device is one of a pneumatic cylinder, a hydraulic cylinder, or an oil cylinder.

[0009] Based on the above technical solutions, preferably, the meter-counting structure includes a base, a meter-counting pressure roller, a mounting plate, and a support roller, wherein the base is disposed on the top of the support frame; the support roller is rotatably connected to the base; the mounting plate is disposed on the top of the base; and the meter-counting pressure roller is rotatably connected to the mounting plate.

[0010] Based on the above technical solutions, preferably, multiple support rollers are arranged horizontally at intervals, and a gap is left between the metering roller and the support roller for the power supply cable to pass through.

[0011] Based on the above technical solutions, preferably, an adjustment assembly is also included. The adjustment assembly includes a lifting hydraulic device, a hydraulic base, a guide rod, and a support bearing. The hydraulic base is disposed above the base and spaced apart from the base. One end of the guide rod is fixedly connected to the base, and the other end is fixedly connected to the hydraulic base.

The lifting hydraulic device is disposed on the top of the hydraulic base, and the output end of the lifting hydraulic device is fixedly connected to the mounting plate.

[0012] Based on the above technical solutions, preferably, it also includes an encoder base, which is disposed on the metering pressure roller and rotates with the rotation of the metering pressure roller.

[0013] Based on the above technical solutions, preferably, the lifting hydraulic device is one of a pneumatic cylinder, a hydraulic cylinder, or an oil cylinder.

[0014] In summary, the self-adjusting damping meter-counting structure provided by this utility model has the following advantages over the prior art: (1) The support frame and the base are directly connected by a shock-absorbing hydraulic device, which can actively buffer the impact force generated by cable vibration and prevent the vibration from being transmitted upward to the metering structure. (2) The shock-absorbing and buffering components are used as auxiliary buffers to further absorb residual vibrations, making them more adaptable. The dual shock absorption effect is adopted to avoid affecting the accuracy of meter counting. (3) By setting shock-absorbing sleeves and damping sleeves, the shock-absorbing buffer components can only move longitudinally, avoiding lateral displacement that could cause the support frame to shake, thus ensuring the stability of the metering structure. (4) The shock-absorbing buffer components and shock-absorbing hydraulic devices can effectively reduce the metering error caused by the jumping of the metering structure due to the vertical jumping of the wires and cables. When the surface texture of the wires and cables changes, the metering effect caused by the jumping can also be reduced by the shock-absorbing buffer components and shock-absorbing hydraulic devices.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0018] See Figures 1-3 Embodiment 1 of this utility model discloses a self-adjusting shock-absorbing meter-counting structure 3, including a shock-absorbing buffer assembly 1, a shock-absorbing hydraulic device 2, a meter-counting structure 3, a support frame 4, and a base 5.

[0019] See Figure 1As shown, in this embodiment 1, the metering structure 3 is set on the top of the support frame 4. The support frame 4 provides an installation foundation for the arrangement of the metering structure 3. The support frame 4 is a plate-shaped structure, and a space is reserved between the support frame 4 and the ground to facilitate the installation and arrangement of subsequent structures.

[0020] See Figure 1 As shown, in this embodiment 1, the base 5 is located below the support frame 4, and the base 5 and the support frame 4 are spaced apart. The base 5 provides space for the installation and movement of the shock absorption and buffer assembly 1. The base 5 does not contact the ground, and there is also space reserved between it and the ground to facilitate the arrangement of the structure.

[0021] See Figure 1 As shown, in this embodiment 1, the shock-absorbing hydraulic device 2 is mounted on the base 5. The shock-absorbing hydraulic device 2 is longitudinally distributed, and its output end is fixedly connected to the support frame 4. This design allows the output end of the shock-absorbing hydraulic device 2 to move up and down, thereby driving the support frame 4 to move up and down. The end of the shock-absorbing hydraulic device 2 furthest from its output end is fixedly connected to the base 5. Specifically, the fixed connection can be achieved by bolts, which is not specifically limited here. It should also be noted that there are two shock-absorbing hydraulic devices 2, and they are symmetrically distributed along the center of the base 5. This arrangement allows the weight of the support frame 4 and the impact force it receives during operation to be evenly transmitted to the base 5, achieving force balance and avoiding unilateral tilting. Moreover, when the support frame 4 is subjected to longitudinal impact, the shock-absorbing hydraulic devices 2 can extend and retract synchronously, using the same damping force to buffer the impact force and avoid unilateral overload.

[0022] The shock-absorbing hydraulic device 2 can be one of a pneumatic cylinder, a hydraulic cylinder, or a hydraulic cylinder. The vibration intensity and load vary depending on the production scenario of the wire and cable. When producing lightweight high-speed wires and cables, the vibration frequency is high but the force is low, so a pneumatic cylinder can be chosen. Utilizing the rapid response characteristics of compressed air, it can absorb high-frequency, low-amplitude vibrations in a timely manner, and its light weight does not add extra load to the support frame 4. When producing heavy-duty, large-diameter wires and cables, the vibration force is high and the duration is long, so a hydraulic cylinder or hydraulic cylinder can be chosen. Through the high damping characteristics of hydraulic oil, it can stably buffer strong vibrations while providing greater support force, preventing the support frame 4 from deforming due to excessive load, thus ensuring both shock absorption and load-bearing effects.

[0023] See Figure 1As shown, in this embodiment 1, the shock-absorbing buffer assembly 1 is disposed between the support frame 4 and the base 5. One end of the shock-absorbing buffer assembly 1 is fixedly connected to the support frame 4, and the other end is fixedly connected to the base 5. The shock-absorbing buffer assembly 1 buffers the impact force through its own deformation, and can transfer the weight of the support frame 4 to the shock-absorbing buffer assembly 1, avoiding force dispersion or displacement. It should also be noted that the shock-absorbing buffer assembly 1 is located at the center point of the base 5, or in other words, the shock-absorbing buffer assembly 1 is disposed at the symmetrical point of the two shock-absorbing hydraulic devices 2. Stable support is achieved through the shock-absorbing hydraulic devices 2 and the shock-absorbing buffer assembly 1, uniformly distributing the core load and preventing local components from being damaged due to long-term overload.

[0024] Specifically, in this embodiment 1, the shock-absorbing buffer component 1 is a shock-absorbing spring 11. One end of the shock-absorbing spring 11 is fixedly connected to the support frame 4, and the other end is fixedly connected to the base 5. The shock-absorbing spring 11 can effectively reduce the metering error caused by the jumping of the metering structure 3 due to the up-and-down jumping of the wire and cable through its own elastic deformation. When the surface texture of the wire and cable changes, the metering effect caused by the jumping can also be reduced by the shock-absorbing buffer component 1 and the shock-absorbing hydraulic device 2.

[0025] When the wire and cable shake up and down, the shock-absorbing buffer assembly 1 and the shock-absorbing hydraulic device 2 will drive the entire metering structure 3 to move with the swing of the cable. At the same time, the shock-absorbing structure composed of the shock-absorbing buffer assembly 1 and the shock-absorbing hydraulic device 2 can generate the opposite counteracting force against the external sudden action, reducing the large-amplitude shaking to the small-amplitude swaying, and ensuring the stability of the wire and cable metering.

[0026] See Figure 1 As shown, in this embodiment 1, a shock-absorbing sleeve 61 and a damping sleeve 62 are also provided. The damping sleeve 62 is sleeved inside the shock-absorbing buffer assembly 1, and the damping sleeve 62 extends out of the bottom of the base 5. The base 5 has a clearance hole for avoiding the damping sleeve 62. The shock-absorbing buffer assembly 1 is disposed on the outer surface of the damping sleeve 62. A portion of the damping sleeve 62 is located below the base 5. The shock-absorbing sleeve 61 is fixedly disposed below the base 5. The top of the shock-absorbing sleeve 61 has an opening. The damping sleeve 62... At least part of it is located inside the damping sleeve 61 and can move longitudinally relative to the damping sleeve 61. The damping sleeve 62 extends into the inside of the damping sleeve 61 from the opening. The damping spring 11 can only extend and retract along the axial direction of the damping sleeve 61 to avoid the damping spring 11 from bending laterally due to uneven force. Furthermore, the damping sleeve 62 can move longitudinally relative to the damping sleeve 61. When it receives an impact, the frictional resistance generated by the sliding of the damping sleeve 62 inside the damping sleeve 61 can consume part of the impact energy.

[0027] The bottom of the shock-absorbing sleeve 61 is provided with a fixing plate 611, which is fixed to the ground to ensure the stability of the overall structure.

[0028] See Figure 2 and Figure 3 As shown, in this embodiment 1, the meter-counting structure 3 includes a base 31, a meter-counting pressure roller 32, a mounting plate 33, and support rollers 34. The base 31 is disposed on the top of the support frame 4 and is fixedly connected to the support frame 4. The support rollers 34 are rotatably connected to the top of the base 31. In this embodiment 1, four support rollers 34 are provided, and the four support rollers 34 are horizontally spaced apart. The mounting plate 33 is disposed on the top of the base 31. The meter-counting pressure roller 32 is rotatably connected to the mounting plate 33. There are two meter-counting pressure rollers 32, and one of the meter-counting pressure rollers 32 is located between two support rollers 34. Above the two support rollers 34, another meter-counting pressure roller 32 is located above the other two support rollers 34. The four support rollers 34 are horizontally spaced to provide uniform support for the wires and cables, preventing sagging or bending due to their own weight or fluctuations during transportation. Moreover, the meter-counting pressure rollers 32 are located above the two support rollers 34, forming a triangular structure. This design allows the pressure of the meter-counting pressure roller 32 to be applied precisely to the area supported by the support rollers 34, avoiding poor contact between the pressure roller and the workpiece due to the workpiece being suspended in the air. This ensures that the meter-counting roller rotates synchronously with the workpiece, thus guaranteeing counting accuracy from the foundation.

[0029] See Figure 2 and Figure 3 As shown, in this embodiment 1, a gap 321 is left between the metering pressure roller 32 and the support roller 34 for the power supply cable to pass through. This design facilitates the prevention of power cables and achieves the metering effect.

[0030] See Figure 2 and Figure 3 As shown, to ensure that the measuring roller 32 can be adjusted to accommodate wires and cables of different diameters, an adjustment assembly 7 is also provided. The adjustment assembly 7 includes a lifting hydraulic device 71, a hydraulic base 72, guide rods 73, and support bearings 74. The hydraulic base 72 is located above the base 31 and is spaced apart from the base 31. One end of the guide rod 73 is fixedly connected to the base 31, and the other end is fixedly connected to the hydraulic base 72. The guide rods 73 are longitudinally distributed, and there are two guide rods 73. There are also two support bearings 74, with each bearing seat fitted onto the outer surface of the two guide rods 73. The mounting plate 33 is fixedly connected to the bearing seats. The lifting hydraulic device 71 is located on top of the hydraulic base 72, and its output end is fixedly connected to the mounting plate 33. The lifting hydraulic device 71 drives the mounting plate 33 and the measuring roller 32 on the mounting plate 33 to achieve longitudinal lifting and lowering, which can accommodate wires and cables of different diameters. Furthermore, the cooperation of the two guide rods 73 and the two support bearings 74 ensures the vertical accuracy of the adjustment process.

[0031] Among them, the lifting hydraulic device 71 can be one of a pneumatic cylinder, a hydraulic cylinder, or an oil cylinder, offering more options.

[0032] See Figure 3 As shown, an encoder base 8 is also provided. The encoder base 8 is set on the metering pressure roller 32 and rotates with the rotation of the metering pressure roller 32. Specifically, the encoder base 8 includes an encoder support rod 82, an encoder cover 81, and an encoder body 83. The encoder cover 81 is fixedly connected to the mounting plate 33 through the encoder support rod 82. The encoder body 83 is set on the encoder cover 81 and is connected to the end of the drive shaft of the metering pressure roller 32 through the encoder cover 81 to realize the rotation of the encoder body 83. Since there are two metering pressure rollers 32, there are also two encoder bodies 83. The dual encoder is used for detection. When the running line length error occurs after calibration, it can be detected in time and dynamically adjusted during operation. Compared with single encoder calibration, it can reduce the waste during calibration and improve sensitivity.

[0033] See Figure 4 As shown, in Embodiment 2 of this utility model, the shock-absorbing sleeve 61 and damping sleeve 62 are removed from Embodiment 1. In this way, the shock-absorbing spring 11 can also achieve a good shock absorption and buffering effect. The base 5 is directly fixed to the ground, and fewer parts are used, resulting in lower cost.

[0034] In the specific implementation steps, the wire and cable will pass through the support roller 34 and the meter counting pressure roller 32. The encoder body 83 will count the length. When the wire and cable shakes up and down, the shock absorption buffer assembly 1 and the shock absorption hydraulic device 2 will drive the base 5 and the meter counting structure 3 above it to move with the cable swing. Moreover, the shock absorption buffer assembly 1 and the shock absorption hydraulic device 2 can generate the opposite counteracting force against the external sudden force, reducing the large-amplitude shaking to a small-amplitude sway. In conjunction with the lifting hydraulic device 71, the pressure of the meter counting pressure roller 32 is automatically adjusted according to the tension to ensure that the wire and cable maintain high stability when the wire diameter is changed, the roundness is poor, or the shaking is severe.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
