Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, specifically to a translational correction mechanism for automatically correcting the position of materials during the winding process. Background Technology

[0002] In many industrial sectors such as textiles, printing, papermaking, film production, and metal strip processing, winding (or coiling) is a common and crucial process. During this process, materials (such as fabrics, films, paper, and foils) need to be wound smoothly and neatly onto a reel.

[0003] However, in actual production, due to various factors such as uneven material tension, initial roll position deviation, equipment mechanical vibration, or guide roller parallelism error, the material is prone to lateral deviation (i.e., misalignment) during its movement. Once misalignment occurs, it leads to uneven winding, forming "snake-like rolls" or "bulging rolls." This not only seriously affects the appearance and quality of the roll but can also cause edge wear, wrinkling, or even breakage, resulting in production interruptions and material waste. On high-speed winding production lines, even minor misalignments, if not corrected in time, will be rapidly amplified in subsequent processes, ultimately leading to the scrapping of the entire roll and causing huge economic losses. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a translational correction mechanism that can accurately and automatically correct material misalignment during the winding process in real time. It also has adjustable clamping and quick release functions to improve production efficiency and winding quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A translational correction mechanism is used for material winding correction in a winding equipment. It is characterized by comprising: a support base, guide groups symmetrically arranged at both ends of the support base, a correction component slidably mounted on the guide groups, and a high-precision drive unit that drives the correction component to move the offset distance along the guide groups according to the material offset distance detected by the inspection unit.

[0007] The correction component includes a movable seat that is slidably mounted on the guide assembly. The two movable seats are equipped with adjustment seats. The adjustment seats are rotatably mounted with a fixed rubber-coated roller. The two adjustment seats are equipped with adjustable height movable blocks. The movable blocks are rotatably mounted with a movable rubber-coated roller that clamps the material with the fixed rubber-coated roller. The position of the movable rubber-coated roller is adjusted by the movable blocks to adjust the clamping force of the fixed rubber-coated roller and the movable rubber-coated roller.

[0008] One of the adjustment seats is equipped with a tensioning mechanism for turning the movable rubber-coated roller in the opposite direction. The movable rubber-coated roller is turned and lifted by the tensioning mechanism to adjust the tightness or looseness of the fixed rubber-coated roller and the movable rubber-coated roller.

[0009] As a further improvement of this utility model, the adjusting seat has a limiting groove for the movable block to move, and a limiting block is provided at the upper end of the limiting groove. A connecting piece with a guide sliding hole is fixedly mounted on the limiting block. A plug screw fixed to the movable block is slidably mounted on the guide sliding hole, and a compression spring is sleeved on the plug screw between the movable block and the connecting piece. This structure uses a compression spring to provide a stable clamping force, ensuring the reliability of clamping.

[0010] As a further improvement of this utility model, a U-shaped limiting plate is provided on the adjusting seat below the limiting groove, and slots that cooperate with the U-shaped limiting plate are provided at both ends of the movable rubber-coated roller. The width of the slots is greater than the thickness of the U-shaped limiting plate. This structure plays a positioning and supporting role when pressed, and serves as a rotation fulcrum when released.

[0011] As a further improvement of this utility model, the tensioning structure includes a telescopic cylinder fixed on the adjusting seat and a swing arm, one end of which is pivotally connected to the output end of the telescopic cylinder and the other end of which is keyed to the movable rubber-coated roller. The telescopic cylinder drives the swing arm, causing it to rotate the movable rubber-coated roller. The slot disengages from the U-shaped limiting plate, causing the U-shaped limiting plate to contact the arc-shaped surface of the movable rubber-coated roller, thereby lifting the movable rubber-coated roller and releasing the fixed rubber-coated roller. This structure achieves a fast and automated release action.

[0012] As a further improvement of this invention, the high-precision drive unit adopts a servo electric cylinder. The servo electric cylinder has the advantages of high control precision, fast response speed, and stable operation, and is key to achieving high-precision deviation correction.

[0013] As a further improvement of this utility model, a clearance groove is provided on the end face of the movable seat corresponding to the fixed rubber-coated roller. This design avoids interference between the movable seat and the end of the fixed rubber-coated roller during translation.

[0014] As a further improvement of this utility model, the movable block has protruding edges formed on both sides, and these protruding edges slide in contact with the side walls of the limiting groove. This design improves the stability of the movable block's lifting movement and prevents it from shaking.

[0015] Compared with the prior art, the translational correction mechanism provided by this utility model brings the following significant benefits:

[0016] 1. High precision and fast response: Using a servo electric cylinder as the drive unit, combined with a high-precision inspection unit, it can detect the edge position of the material in real time and quickly calculate the offset, driving the entire correction component to perform precise translation compensation at the millimeter or even micrometer level. The response speed is fast and the correction accuracy is far higher than that of traditional pneumatic / hydraulic methods, making it particularly suitable for high-speed, high-precision modern production lines.

[0017] 2. Flexible and adjustable clamping pressure: By moving the moving block up and down within the limiting groove, the clamping pressure between the moving rubber-coated roller and the fixed rubber-coated roller can be flexibly adjusted. This design can adapt to materials of different thicknesses and materials, ensuring that sufficient friction is provided for correction without damaging the material surface.

[0018] 3. Quick release and clamping function: The unique loosening and clamping structure design, driven by a cylinder, allows the moving rubber-coated roller to rotate and be lifted easily, quickly separating it from the fixed rubber-coated roller. This function greatly simplifies the operation process of feeding, initial alignment, roll changing, and handling jams, saving downtime and improving equipment utilization and production efficiency.

[0019] 4. Stable and reliable operation: The guide assembly ensures the linearity and smoothness of the translational movement of the correction component. The engagement of the convex edge of the moving block with the limiting groove, the engagement of the plug screw with the guide slide hole, and the constant force applied by the compression spring jointly ensure the stability and consistency of the clamping mechanism during operation, avoiding accidental loosening or pressure fluctuations caused by vibration or other reasons.

[0020] 5. High degree of automation and intelligence: This mechanism can be integrated with a central control system to achieve fully automatic closed-loop control. From detection and calculation to execution of corrective actions, the entire process requires no manual intervention, reducing human error and realizing intelligent and continuous production.

[0025] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0026] See Figures 1 to 4 The present embodiment provides a translational correction mechanism, which includes a support base 1, a high-precision drive unit 2, a guide group 3, and a correction component 4.

[0027] Specifically, the support base 1 serves as the basic frame of the entire mechanism, and two sets of symmetrical linear guide rails are fixed to its two ends by bolts to serve as guide groups 3.

[0028] The high-precision drive unit 2 uses a set of servo electric cylinders, whose cylinder bodies are fixed on the support base 1, and the end of the push rod of the electric cylinder is connected to a movable seat 41 in the correction component 4.

[0029] The alignment component 4 includes two movable seats 41, each with its bottom slidably connected to a corresponding linear guide rail via a slider. Each of the two movable seats 41 has an adjusting seat 42 fixed on it. A fixed rubber-coated roller 43 is rotatably mounted between the two adjusting seats 42 via bearings. Furthermore, two balance supports 411 are provided between the two movable seats 41 to ensure their stability.

[0030] The two movable seats 41 have clearance grooves on their end faces corresponding to the fixed rubber-coated roller 43. This design prevents the movable seats 41 from interfering with the ends of the fixed rubber-coated roller 43 during translation.

[0031] Each adjusting seat 42 has a vertical limiting groove 421. A movable block 44 is slidably disposed within the limiting groove 421 by engaging with the sidewalls of the limiting groove 421 via its two formed protrusions 441. A limiting block 45 is fixed to the upper end of the limiting groove 421, and a connecting piece 46 is fixed to the limiting block 45, which has a guide sliding hole. The lower end of a screw 47 is threaded to the movable block 44, and the upper end passes through the guide sliding hole of the connecting piece 46. A compression spring 48 is fitted on the shaft of the screw 47 between the movable block 44 and the connecting piece 46.

[0032] A movable rubber-coated roller 49 is rotatably mounted between two movable blocks 44 via bearings, parallel to and corresponding to a fixed rubber-coated roller 43. Material passes between the fixed rubber-coated roller 43 and the movable rubber-coated roller 49. The elastic force of the compression spring 48 is transmitted to the movable rubber-coated roller 49 through the movable blocks 44, causing it to press the material firmly against the fixed rubber-coated roller 43. The compression spring 48 can be compressed or released by turning the stop screw 47, thereby adjusting the clamping force.

[0033] On each adjusting seat 42, a U-shaped limiting plate 410 is fixed below the limiting groove 421. The corresponding end of the movable rubber-coated roller 49 is provided with a slot that mates with it. During normal operation, the slot is engaged with the U-shaped limiting plate 410, serving to support and position the roller.

[0034] A tensioning structure 5 is also installed on one of the adjusting seats 42. The tensioning structure 5 includes a telescopic cylinder 51 fixed to the adjusting seat 42 by a bracket. One end of a swing arm 52 is hinged to the piston rod end of the telescopic cylinder 51 by a pin, and the other end is connected to the shaft end of the movable rubber-coated roller 49 by a flat key. The swing arm 52 has a groove for the pin to move, so that the pin has room to move when the movable rubber-coated roller 49 is raised, thus preventing the swing arm 52 from deforming. The telescopic cylinder 51 drives the swing arm 52, causing the swing arm 52 to rotate the movable rubber-coated roller 49. The slot disengages from the U-shaped limiting plate 410, so that the U-shaped limiting plate 410 contacts the arc-shaped surface of the movable rubber-coated roller 49, thereby raising the movable rubber-coated roller 49 and releasing the fixed rubber-coated roller 43 and the movable rubber-coated roller 49. This structure realizes a fast and automated release action.

[0035] Working principle:

[0036] During operation, the inspection unit (not shown in the figure) monitors the edge position of the material in real time. When lateral deviation of the material is detected, the control system calculates the deviation amount and direction and drives the servo electric cylinder. The push rod of the servo electric cylinder pushes or pulls the correction component 4 to move laterally along the guide group 3. The distance moved is exactly equal to the deviation distance of the material, thereby pulling the material back to the correct position before it enters the reel, thus achieving correction.

[0037] When material feeding or handling abnormalities is required, the control system activates the telescopic cylinder 51. The piston rod of the telescopic cylinder 51 extends, pushing the swing arm 52. The swing arm 52 drives the movable rubber-coated roller 49 to rotate in the opposite direction (opposite to the normal rotation direction) by a small angle. At this time, the slot at the end of the movable rubber-coated roller 49 disengages from the U-shaped limiting plate 410, and the upper edge of the U-shaped limiting plate 410 contacts the arc-shaped outer surface of the movable rubber-coated roller 49. As the cylinder 51 continues to extend, the swing arm 52, with the roller as the fulcrum, actually generates a component force that lifts the movable rubber-coated roller 49 upward, thereby overcoming the elastic force of the compression spring 48, causing the movable rubber-coated roller 49 to rise rapidly and separate from the fixed rubber-coated roller 43, forming a larger gap for easy operation. After handling, the telescopic cylinder 51 retracts, pushing the swing arm 52 to make the movable rubber-coated roller 49 rotate and descend, the slot re-engages into the U-shaped limiting plate 410, and the mechanism returns to the clamped state.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
