Description

Technical Field

[0001] This invention relates to the field of wire mesh processing and leveling technology, and in particular to a wire mesh constant tension leveling and automatic deviation correction device based on roll diameter recognition. Background Technology

[0002] Wire mesh materials are widely used in printing, filtration, textiles, precision machining and other industries. During the unwinding, conveying and rewinding process, wire mesh is easily affected by factors such as uneven raw material roll diameter, conveying tension fluctuations, equipment assembly errors, and running vibrations, resulting in defects such as surface wrinkles, local bulges, uneven stress on the width, and burrs, dust and impurities adhering to the edges, which seriously affect the accuracy of subsequent processing and the quality of finished products.

[0003] Currently, most traditional wire mesh leveling equipment uses a rigid pressure roller fixed-point extrusion leveling method. The pressure of the pressure roller is fixed and cannot adapt to the concave and convex deformation of the wire mesh. This easily leads to problems such as excessive pressure in some areas damaging the wire mesh, and insufficient pressure in others resulting in incomplete leveling. The leveling uniformity is poor and the adaptability is low. At the same time, the leveling mechanism and the scraping mechanism of the existing equipment are mostly independently driven, with a complex structure that requires multiple sets of electrical control synchronization systems to match and operate. The equipment has high energy consumption, high failure rate, and poor synchronization accuracy. It is very easy to cause problems such as wire mesh stretching, deviation, and scratch damage due to asynchronous power. In addition, traditional equipment lacks a linkage pneumatic compensation leveling structure and a flexible scraping structure, and cannot complete the fine cleaning of wire mesh edges while leveling. The process is simple, the processing efficiency is low, and it is difficult to adapt to the continuous and stable processing and production of wire mesh with different roll diameters and specifications. It has obvious technical defects and limitations in use. Summary of the Invention

[0004] This invention provides a wire mesh constant tension leveling and automatic deviation correction device based on roll diameter recognition. It adopts a passive linkage structure and relies on the friction force of wire mesh conveying to achieve integrated leveling and scraping operations. It does not require an additional electrical control synchronization system and independent drive mechanism. The structure is simple, energy consumption is low, and failure rate is low. Through the interconnected air pressure adaptive leveling structure, it solves the industry pain points of uneven pressure on the web, poor leveling effect, and easy damage to wire mesh in traditional wire mesh leveling equipment. At the same time, with the flexible edge scraping structure, the wire mesh leveling and edge cleaning processes can be completed simultaneously, improving the quality and efficiency of wire mesh processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wire mesh constant tension leveling and automatic deviation correction device based on roll diameter recognition is provided, including a machine frame; The equipment frame is equipped with an unwinding assembly, a rewinding assembly, and a middle leveling linkage mechanism.

The winding assembly adopts a sliding adaptive correction winding structure. Combined with the speed reduction and torque increase characteristics of the reducer, it can adaptively and finely adjust the winding position and winding torque according to the changes in the unwinding diameter of the wire mesh and the fluctuations in the conveying tension, and compensate for the conveying deviation in real time. The central leveling linkage mechanism includes a central driven main shaft, an air pressure adaptive leveling component, and an edge scraping component; The central driven spindle is rotatably mounted on one side of the equipment frame and located on the wire mesh conveying path between the unwinding air shaft and the rewinding air shaft. The friction of the wire mesh travel drives the central driven spindle to rotate passively.

[0006] Preferably, the pneumatic adaptive leveling assembly includes multiple sets of telescopic sealing leveling units arranged in an axial array. These telescopic sealing leveling units are evenly installed on the outer side of the central driven spindle. Each telescopic sealing leveling unit includes a circular plate, a cylinder, a piston plate, a sealing ring, a return spring, a connecting rod, a mounting plate, a stretching plate, and an arc-shaped head. The circular plate is fixedly sleeved on the outer surface of the central driven spindle, and the cylinder is fixedly installed on the outer surface of the circular plate. The piston plate is slidably and sealingly embedded inside the cylinder. The sealing ring is fitted onto the outer circle of the piston plate and seals against the inner wall of the cylinder. The return spring is located inside the cylinder, with its two ends respectively connecting to the inner wall of the cylinder and the piston plate. The multiple leveling units fully cover the width of the wire mesh and employ an independent telescopic and overall pneumatic linkage structure design, enabling flexible adaptive leveling and avoiding the localized damage and leveling dead angles caused by the fixed-point extrusion of traditional rigid pressure rollers.

[0007] Preferably, a connecting rod is fixedly connected to the outer side of the piston plate, and a mounting plate and a stretching plate are fixedly fixed to the outer end of the connecting rod in sequence. The end of the stretching plate is provided with an arc-shaped head for bonding with the wire mesh. The stretching plate adopts a flexible bonding and arc transition structure with no sharp contact parts, which can realize surface contact flexible rolling stretching, increase the bonding area with the wire mesh, disperse the leveling pressure, and protect the warp and weft structure of the wire mesh to the greatest extent while ensuring the leveling effect.

[0008] Preferably, the cylinders of the multiple sets of telescopic sealing and leveling units are connected by a connecting pipeline, and the internal cavities of all cylinders are interconnected through the connecting pipeline to form an interconnected closed air pressure linkage compensation structure. This closed air pressure linkage structure can realize dynamic and balanced pressure distribution, single-point pressure and full-area compensation, automatically adapt to local concave and convex deformation of the wire mesh, and ensure uniform force on the entire wire mesh surface.

[0009] Preferably, the edge scraping assembly includes a belt drive unit, a speed change and reversing drive unit, and an elastic scraping execution unit that are sequentially linked. The belt drive unit includes a support base, a rotating shaft, a drive pulley, a transmission belt, and a driven pulley. The support base is fixedly mounted on one side of the equipment frame, the rotating shaft is rotatably mounted between the support bases, and the drive pulley is fixedly sleeved on the outer surface of the rotating shaft.

[0010] Preferably, the driven pulley is fixedly installed at both ends of the central driven main shaft, and the driving pulley and the driven pulley are connected by friction transmission through a transmission belt.

[0011] Preferably, the speed-changing transmission unit includes a transmission shaft, a first bevel gear, a support plate, a transmission rod, and a second bevel gear; the transmission shaft is fixedly disposed at the end of the rotating shaft, and the first bevel gear is fixedly disposed at the end of the transmission shaft.

[0012] Preferably, the support plate is fixedly installed on the top side of the equipment frame, the transmission rod is rotatably assembled between the support plates through bearings, the second bevel gear is fixed to one end of the transmission rod, and the first bevel gear and the second bevel gear mesh vertically to drive each other. The vertical meshing of the bevel gear set realizes power reversal and speed change adaptation, and the scraping speed can be adjusted according to different wire mesh thicknesses and impurity conditions.

[0013] Preferably, a protective box is fixedly installed on the side wall of the equipment frame. The protective box covers the outer side of the meshing of the first bevel gear and the second bevel gear. The protective box can isolate dust and wire mesh debris generated during the processing and prevent impurities from entering the gear meshing gap and causing jamming and wear.

[0014] Preferably, the elastic scraping execution unit includes a support plate, elastic sheets, and an arc-shaped scraper; multiple elastic sheets are circumferentially and evenly fixed to the outer surface of the transmission rod, the support plate is fixedly arranged on the outer side of the elastic sheets, and the arc-shaped scraper is fixedly arranged on the outer side of the support plate. The arc-shaped scraper is set to fit the edge of the wire mesh and rotates with the transmission rod to realize edge scraping operation. The circumferential array flexible scraping structure can realize continuous cyclic cleaning without dead corners. The elastic structure can adapt to the slight undulations of the wire mesh edge, flexibly scraping away burrs and dust, taking into account both cleaning effect and material protection.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows: This invention employs an integrated frame structure, precisely linking the unwinding assembly, the central leveling linkage mechanism, and the rewinding assembly. Utilizing the friction force of the wire mesh conveyor, it achieves passive linkage operation of the leveling and scraping structures, eliminating the need for multiple independent drive mechanisms and electrical control synchronization systems. This simplifies the overall equipment structure, reduces energy consumption, processing costs, and operational failure rates. Simultaneously, it avoids wire mesh stretching and misalignment issues caused by asynchronous power sources. By setting multiple array-type telescopic sealing leveling units in conjunction with connecting pipelines to form an interconnected, sealed air pressure linkage compensation structure, it achieves single-point pressure application and full-width adaptive pressure compensation leveling, adapting to the wire mesh's movement. The device adaptively adjusts the bonding pressure to accommodate wrinkles and bulges on the wire mesh surface, and performs flexible rolling leveling throughout the process. This effectively eliminates uneven force on the wire mesh surface, significantly improving the leveling accuracy and flatness of the wire mesh, while avoiding damage caused by rigid extrusion. It is suitable for leveling processing needs of wire meshes of different specifications and roll diameters. At the same time, the invention uses a belt drive and bevel gear speed change mechanism to drive the flexible scraping execution unit, which can simultaneously complete the adaptive flexible scraping and cleaning of burrs, dust, and impurities on the wire mesh edges with the leveling operation. This achieves integrated continuous operation of leveling and impurity removal, simplifying processing steps and improving wire mesh processing efficiency and finished product quality.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figures 1 to 8 As shown, the present invention provides a wire mesh constant tension leveling and automatic correction device based on roll diameter recognition, including a machine frame 1; the machine frame 1 is equipped with an unwinding assembly, a winding assembly, and a middle leveling linkage mechanism. The machine frame 1 serves as the load-bearing foundation structure of the whole machine, providing high strength and high stability support, and providing an installation reference for the functional components above. The unwinding assembly, the middle leveling linkage mechanism, and the winding assembly are arranged and assembled in sequence from front to back along the wire mesh conveying direction on the corresponding installation positions of the machine frame 1. All structures are coaxial and aligned with the same reference, forming a continuous wire mesh conveying production line.

[0027] Furthermore, the unwinding assembly includes an unwinding air shaft 101, an unwinding drive motor 102, a paper tube support platform 103, and an unwinding guide roller 107. The unwinding drive motor 102, the paper tube support platform 103, and the unwinding guide roller 107 are all fixedly installed on one side of the equipment frame 1. The unwinding air shaft 101 is rotatably installed on one side of the equipment frame 1 and is connected to the unwinding drive motor 102 for transmission.

[0028] In actual use, the wire mesh raw material roll to be processed is sleeved on the surface of the unwinding air shaft 101. The expansion of the unwinding air shaft 101 achieves tight fixation with the paper tube, preventing the raw material roll from slipping during rotation. The paper tube support platform 103 can provide auxiliary support to the end of the raw material roll, avoiding cantilever deformation of large-diameter wire mesh raw material rolls and improving unwinding stability. The unwinding drive motor 102 serves as the unwinding power source, driving the unwinding air shaft 101 to rotate at a uniform speed, achieving smooth unwinding and conveying of the wire mesh. At the same time, the unwinding guide roller 107 can limit and guide the output wire mesh, correct the wire mesh conveying angle, and avoid problems such as wire mesh deviation, wrinkles, and deviation during unwinding, providing a regular conveying substrate for subsequent leveling operations.

[0029] Furthermore, the winding assembly includes a winding platform 104, a winding air shaft 105, and a winding reducer 106. The winding platform 104 is slidably mounted on one side of the equipment frame 1, and the winding reducer 106 is fixedly installed on one side of the winding platform 104. The winding air shaft 105 is rotatably mounted on the winding platform 104 and is connected to the winding reducer 106 for transmission. As a storage structure for the processed wire mesh, the winding reducer 106 can reduce the speed and increase the torque of the driving power, ensuring that the winding air shaft 105 operates at low speed and high torque, which is suitable for the flat winding requirements of the wire mesh. The winding air shaft 105 also uses an air-filled fixing method to store the processed wire mesh, which is convenient to disassemble and install and is firmly fixed. At the same time, the winding platform 104 can slide slightly relative to the equipment frame 1, which can cooperate with the equipment correction structure to achieve adaptive fine adjustment of the winding position, effectively solving the problems of unilateral offset and uneven winding that occur during the long-term winding of the wire mesh, and ensuring the regularity of the finished winding product.

[0030] Please see Figures 1 to 8 In one embodiment, the central leveling linkage mechanism includes a central driven spindle 2, an air pressure adaptive leveling component, and an edge scraping component. The central driven spindle 2 is rotatably mounted on one side of the equipment frame 1 and located on the wire mesh conveying path between the unwinding air shaft 101 and the rewinding air shaft 105. The friction of the wire mesh travels drives the central driven spindle 2 to rotate passively. The wire mesh continues to travel at a constant speed under the traction of the unwinding and rewinding components. The friction of the wire mesh itself drives the central driven spindle 2 to rotate passively, realizing passive power acquisition, simplifying the overall structure of the equipment, reducing equipment energy consumption and failure rate, and ensuring that the spindle rotation speed is synchronized with the wire mesh conveying speed, eliminating problems such as wire mesh stretching, wrinkling, and scratching caused by speed difference.

[0031] Please see Figures 1 to 8In one embodiment, the air pressure adaptive leveling assembly includes multiple sets of telescopic sealing leveling units arranged in an axial array. The multiple sets of telescopic sealing leveling units are evenly installed on the outside of the central driven main shaft 2. The telescopic sealing leveling unit includes a circular plate 201, a cylinder 202, a piston plate 203, a sealing ring 204, a return spring 205, a connecting rod 206, a mounting plate 207, a stretching plate 208, and an arc-shaped head 209. The circular plate 201 is fixedly sleeved on the outer surface of the central driven main shaft 2. The cylinder 202 is fixedly installed on the outer surface of the circular plate 201. The piston plate 203 is slidably and sealingly embedded in the cylinder 202. The sealing ring 204 is sleeved on the outer circle of the piston plate 203 and seals against the inner wall of the cylinder 202. The return spring 205 is located inside the cylinder 202 and its two ends are respectively connected to the inner wall of the cylinder 202 and the piston plate 203.

[0032] Specifically, multiple sets of circular plates 201 are equidistantly arranged along the central driven main shaft 2, which ensures that the leveling unit covers the entire width of the wire mesh and realizes full-width leveling operation. The sealing ring 204 is tightly attached to the inner wall of the cylinder 202 to form a reliable sliding sealing structure to prevent gas leakage inside the cylinder 202. The return spring 205 is normally kept in a slightly compressed state to provide return elasticity for the piston plate 203, ensuring that the leveling unit can quickly return to its original position after being compressed and retracted, thus realizing cyclic adaptive leveling.

[0033] Furthermore, a connecting rod 206 is fixedly connected to the outer side of the piston plate 203. A mounting plate 207 and a stretching plate 208 are sequentially fixed to the outer end of the connecting rod 206. An arc-shaped head 209 for adhering to the wire mesh is provided at the end of the stretching plate 208. The connecting rod 206 serves as a transmission connection, stably transmitting the extension and retraction power of the piston plate 203 to the stretching plate 208 and the arc-shaped head 209. The arc-shaped head 209 adopts a rounded transition structure without sharp edges, which can flexibly adhere to the surface of the wire mesh and avoid rigid compression and scratching of the wire mesh. As the central driven main shaft 2 continues to rotate, multiple sets of arc-shaped heads 209 intermittently contact the surface of the wire mesh in sequence, rolling and stretching the wire mesh in segments, gradually spreading out the fine wrinkles, bulges and wave deformations on the surface of the wire mesh, and effectively releasing the residual stress generated during the wire mesh conveying process.

[0034] Please see Figures 1 to 8In one embodiment, a connecting pipe 210 is provided between the cylinders 202 of multiple sets of telescopic sealing and leveling units. The internal cavities of all cylinders 202 are interconnected through the connecting pipe 210, forming an interconnected, sealed, air pressure linkage compensation structure. When there are bulges or protrusions in the wire mesh, the arc-shaped head 209 is pressed first, pushing the piston plate 203 to compress the gas inside the cylinder 202. The pressurized gas is quickly diverted to the interior of all other cylinders 202 through the connecting pipe 210, utilizing the characteristic of equal air pressure transmission. The piston plate 203, which is not under pressure, extends outward, causing the corresponding arc-shaped head 209 to fit against the flat area of ​​the wire mesh. This achieves the effect of single-point pressure and full-width compensation, ensuring uniform force across the entire wire mesh surface. This solves the problems of incomplete flattening and wire mesh damage caused by excessive or insufficient local pressure in traditional independent pressure block structures. After the bulge area has passed the flattening position, the return spring 205 pulls the piston plate 203 to reset, the gas inside the cylinder flows back, and the equipment returns to its initial state, ready for the next adaptive flattening operation.

[0035] Please see Figures 1 to 8 In one embodiment, the edge scraping assembly includes a belt drive unit, a speed-changing transmission unit, and an elastic scraping execution unit that are sequentially linked. The belt drive unit includes a support base 3, a rotating shaft 301, a drive pulley 302, a transmission belt 303, and a driven pulley 304. The support base 3 is fixedly installed on one side of the equipment frame 1, the rotating shaft 301 is rotatably mounted between the support bases 3, the drive pulley 302 is fixedly sleeved on the outer surface of the rotating shaft 301, and the driven pulley 304 is fixedly installed at both ends of the central driven main shaft 2. The drive pulley 302 and the driven pulley 304 are connected by friction transmission through the transmission belt 303. The edge scraping assembly passively takes power from the rotation of the central driven main shaft 2 throughout the entire process, without the need for a separate drive motor. The power synchronization is extremely high, and it can completely match the scraping frequency with the wire mesh conveying speed. Through the belt friction transmission, it has an overload buffering effect, which can effectively avoid structural damage caused by material jamming and improve the stability of equipment operation.

[0036] Please see Figures 1 to 8 In one embodiment, the speed-changing transmission unit includes a drive shaft 305, a first bevel gear 306, a support plate 4, a drive rod 401, and a second bevel gear 402. The drive shaft 305 is fixedly disposed at the end of the rotating shaft 301, the first bevel gear 306 is fixedly disposed at the end of the drive shaft 305, the support plate 4 is fixedly disposed on the top side of the equipment frame 1, the drive rod 401 is rotatably assembled between the support plates 4 via bearings, the second bevel gear 402 is fixed to one end of the drive rod 401, and the first bevel gear 306 and the second bevel gear 402 mesh vertically. A protective box 406 is fixedly disposed on the side wall of the equipment frame 1, and the protective box 406 covers the meshing outside of the first bevel gear 306 and the second bevel gear 402.

[0037] Specifically, when the rotating shaft 301 rotates, it drives the transmission shaft 305 and the first bevel gear 306 to rotate synchronously. Through the vertical meshing structure of the two sets of bevel gears, the horizontal rotational power is converted into vertical rotational power, realizing the reversal of the transmission direction. At the same time, the two sets of bevel gears have different numbers of teeth, which can realize speed adjustment. The optimal scraping speed can be adapted according to the wire mesh specifications and the stubbornness of impurities, thereby improving the impurity removal effect. The protective box 406 can fully enclose the gear meshing area to prevent wire mesh debris and dust from entering the gear gap, avoid gear jamming and abnormal wear, and extend the service life of the transmission structure.

[0038] Please see Figures 1 to 8 In one embodiment, the elastic scraping execution unit includes a support plate 403, elastic sheets 404, and an arc-shaped scraper 405. Multiple elastic sheets 404 are circumferentially and uniformly fixed to the outer surface of the transmission rod 401. The support plate 403 is fixedly arranged on the outer side of the elastic sheets 404, and the arc-shaped scraper 405 is fixedly arranged on the outer side of the support plate 403. The arc-shaped scraper 405 is set to fit the edge of the wire mesh and rotates with the transmission rod 401 to realize edge scraping operation. The multiple elastic sheets 404 are arranged in a ring array to realize continuous cyclic scraping operation without cleaning dead corners. The elastic sheets 404 have elastic deformation capability, so that the arc-shaped scraper 405 forms a flexible scraping structure. During the operation, it can adaptively fit the slight undulations of the wire mesh edge, which can not only scrape off the burrs, debris, dust and other impurities on the edge of the wire mesh, but also avoid the problem of tearing and wear of the wire mesh edge caused by rigid scraping.

[0039] Working principle and process: When the equipment is running, the wire mesh raw material roll is first fixed on the unwinding air shaft 101. The unwinding drive motor 102 drives the unwinding air shaft 101 to rotate, and the unwinding guide roller 107 completes the smooth unwinding of the wire mesh. The paper tube support table 103 provides auxiliary support for the raw material roll to ensure stable unwinding. After unwinding, the wire mesh passes through the middle driven main shaft 2 along the conveying path and is finally stored on the winding air shaft 105. The winding reducer 106 provides stable torque for the winding operation and completes the uniform winding of the wire mesh. During the continuous conveying of the wire mesh, the friction between itself and the central driven main shaft 2 drives the main shaft to rotate passively. The main shaft drives multiple sets of leveling units on the outside to rotate synchronously, and the arc head 209 intermittently rolls the surface of the wire mesh. When it comes into contact with the bulge or wrinkle area of ​​the wire mesh, the arc head 209 is pressed and pushes the piston plate 203 through the connecting support rod 206 to compress the gas inside the cylinder 202. The gas is diverted to the other cylinders 202 through the connecting pipe 210, driving the other leveling units to extend adaptively, realizing full-width pressure balance compensation, flexibly flattening the wire mesh wrinkles, and the return spring 205 completes the piston return cycle. At the same time, the rotation of the central driven main shaft 2 drives the end driven pulley 304 to rotate, which in turn drives the drive pulley 302 and the rotating shaft 301 to rotate via the transmission belt 303. The power is reversed and the speed is changed via the transmission shaft 305, the first bevel gear 306, and the second bevel gear 402, driving the transmission rod 401 to rotate. The transmission rod 401 drives the multiple sets of elastic plates 404 and the arc-shaped scraper 405 on the outer side to rotate in a cycle, continuously and flexibly scraping the edges of the wire mesh to remove burrs and attached impurities. Finally, the leveled and impurity-removed wire mesh is wound up by the winding assembly.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
