Machine vision-based dynamic deviation correction structure for magnetic filter belt

Abstract

This invention relates to the field of paper tape correction technology and discloses a machine vision-based dynamic deviation correction structure for magnetic filter tape. The structure includes a liquid storage frame and a waste collection frame. A magnetic roller is fixedly connected to the top right side of the liquid storage frame. Inclined baffles are fixedly connected to the front and back sides of the inner wall of the liquid storage frame. A protective cover is fixedly connected to the top left side of the liquid storage frame. When the paper tape becomes skewed, a small motor starts and drives the correction roller frame to rotate, causing the correction roller frame to tilt. Through a synchronization component and a squeezing component, the squeezing roller descends and squeezes the paper tape, squeezing out the waste liquid adsorbed in the paper tape. This also ensures that the paper tape makes full contact with the rollers in the correction roller frame, increasing the friction between the paper tape and the rollers in the correction roller frame. This facilitates the correction roller frame in adjusting the direction of the paper tape's movement, solving the problem that the paper tape easily slips after becoming wet, making it difficult for the correction roller frame to change the direction of the paper tape's deviation, thereby quickly correcting the position of the paper tape.

Description

Technical Field

[0001] This invention relates to the field of paper tape correction equipment technology, specifically a dynamic deviation correction structure for magnetic filter tape based on machine vision. Background Technology

[0002] Magnetic roller paper belt filters are widely used for solid-liquid separation and circulation purification of industrial coolants such as cutting fluids and grinding fluids. The core filtration component is a paper belt magnetic filter. This type of equipment uses magnetic rollers to adsorb ferromagnetic impurities and paper belts to intercept non-magnetic particles, achieving continuous filtration. The paper belt circulates under the traction of drive rollers, guide rollers, and tension rollers, completing actions such as filtration, slag discharge, and replacement. This is crucial for ensuring filtration efficiency and stable equipment operation. The magnetic filter belt dynamic deviation correction structure based on machine vision is a non-contact, high-precision, real-time closed-loop intelligent deviation correction system. Its core is to use vision to detect the lateral deviation of the magnetic filter belt in real time.

[0003] When conveying magnetic filter paper tape, the constraint on the paper tape is relatively weak, and the paper tape is prone to deviation. The common correction method usually relies on changing the swing angle of the correction roller and using friction to make the paper tape automatically return to the correct position. However, when the paper tape comes into contact with the coolant, the paper tape will become wet. Wetness will significantly reduce the friction between the paper tape and the roller, and at the same time weaken the rigidity of the paper tape itself, making it difficult to effectively guide the paper tape back to the correct position, and easily causing the paper tape to deviate by a large angle. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a machine vision-based dynamic deviation correction structure for magnetic filter belts, comprising a liquid storage frame and a waste collection frame. A magnetic roller is fixedly connected to the top right side of the liquid storage frame. Inclined baffles are fixedly connected to both the front and back sides of the inner wall of the liquid storage frame. A protective cover is fixedly connected to the top left side of the liquid storage frame. Two vision inspection instruments are fixedly connected to the right side of the outer wall of the protective cover. The structure also includes: The conveying mechanism is rotatably mounted on the inner wall of the liquid storage frame; The correction mechanism is fixedly installed on the front and back of the inner wall of the liquid storage frame; The blocking mechanism is fixedly installed on the top of the outer wall of the liquid storage frame; In operation, the operator lays the paper strip flat on top of the liquid storage frame using a conveying mechanism. As the paper strip moves, it comes into contact with the inclined baffle, causing the edges of the paper strip to bend. Then, the magnetic roller mill is started, and the waste liquid to be treated is discharged into the magnetic roller mill. The magnetic roller mill adsorbs metal fragments from the waste liquid, and the adsorbed metal fragments fall onto the top of the paper strip. The waste liquid undergoes secondary filtration by permeating the paper strip, and the filtered waste liquid falls into the liquid storage frame. Finally, the metal fragments adsorbed by the magnetic roller mill are discharged into the waste collection frame for collection.

[0005] Preferably, the conveying mechanism includes: A rotating assembly is rotatably mounted on the inner wall of the liquid storage frame; The drive component is mounted on the inner wall of the protective cover.

[0006] Preferably, the correction mechanism includes: The oscillation assembly is fixedly installed on the front and back of the inner wall of the liquid storage frame by fasteners; The fasteners include six mounting plates fixedly connected to the front and back of the inner wall of the liquid storage frame, and small motors are fixedly connected to the bottom of the outer wall of each of the twelve mounting plates. The synchronization component is installed on the top of the outer wall of the mounting plate.

[0007] Preferably, the blocking mechanism includes: The extrusion assembly is fixedly installed on the top of the outer wall of the liquid storage frame; Clear the component; the clear component slide setting is located on the inner wall of the synchronization component.

[0008] Preferably, the rotating assembly includes four rotating holes 1 opened in the inner wall of the liquid storage frame, the four rotating holes 1 are in pairs, and the inner walls of the two pairs of rotating holes 1 are rotatably connected to a sprocket rod. The inner wall of the liquid storage box is equipped with a conveyor chain, and the outer walls of the two sprocket rods are engaged with the inner wall of the conveyor chain.

[0009] Preferably, the drive assembly includes two rotating holes two of the inner wall of the protective cover, a paper tape roller is rotatably connected to the inner wall of the two rotating holes two, and a drive motor is fixedly connected to the back of the outer wall of the liquid storage frame. The back of the sprocket rod on the left side is fixedly connected to the front of the output end of the drive motor; In operation, the operator pulls the paper tape in the paper tape roller to lay the paper tape on top of the conveyor chain. Then, the drive motor is started to drive the sprocket rod on the left side to rotate, which in turn drives the conveyor chain to rotate, thus moving the paper tape.

[0010] Preferably, the skew assembly includes twelve skew-correcting roller frames disposed on the inner wall of the liquid storage frame, the bottom of each of the twelve skew-correcting roller frames being fixedly connected to the top of the output end of twelve small motors; The outer walls of the twelve straightening roller frames are rotatably connected to the inner walls of the twelve mounting plates, and the side of the twelve straightening roller frames closest to the inner wall of the liquid storage frame is fixedly connected to a connecting plate. During the conveyor belt transport process, the edge of the paper belt is photographed in real time by a vision inspection device to monitor the movement of the paper belt and whether the paper belt is skewed. When the paper belt is skewed, a small motor will start to drive the correction roller frame to rotate, change the swing direction of the correction roller frame, tilt the correction roller frame, and change its contact angle with the paper belt.

[0011] Preferably, the synchronization component includes a rotating frame disposed on the top of the outer wall of the mounting plate, and the inner wall of each of the twelve rotating frames has two rotating holes three. The twenty-four rotating holes three are grouped in pairs, and the inner wall of each of the twelve groups of rotating holes three is rotatably connected to a squeezing roller. The twelve rotating frames are slidably connected to the inner walls of the twelve connecting plates on the side closest to the inner wall of the liquid storage frame, and spring rods are fixedly connected to the bottom of the twelve rotating frames. Each of the twelve connecting plates has a sliding hole on its inner wall, and the inner wall of each of the twelve sliding holes is slidably connected to the outer wall of each of the twelve spring rods. When the correction roller frame rotates, it drives the connecting plate to rotate, which in turn drives the rotating frame and the extrusion roller to rotate.

[0012] Preferably, the extrusion assembly includes twelve arc-shaped inclined rings fixedly connected to the top of the liquid storage frame, and spherical rods fixedly connected to the top of the outer walls of the twelve rotating frames; The tops of the twelve spherical rods are rotatably connected to the bottoms of the twelve arc-shaped inclined rings, and the outer walls of the twelve extrusion rollers are all provided with spiral grooves; The rotating frame drives the spherical rod to contact the inclined surface of the arc-shaped inclined ring, causing the spherical rod to be squeezed. This pushes the rotating frame, the squeeze roller, and the spring rod to descend, causing the spring rod to be squeezed and accumulate rebound force. The descending squeeze roller will contact the paper tape, thereby squeezing the paper tape and squeezing out the waste liquid adsorbed in the paper tape. It also makes the paper tape fully contact the roller in the correction roller frame, increasing the friction between the paper tape and the roller in the correction roller frame. This makes it easier for the correction roller frame to adjust the moving direction of the paper tape, solving the problem that the paper tape is prone to slippage after it gets wet, making it difficult for the correction roller frame to change the offset direction of the paper tape. This allows for quick correction of the paper tape's position. During the continuous transport of the paper belt by the conveyor chain, the squeeze roller is affected by the friction between itself and the paper belt, causing the squeeze roller to rotate. During its rotation, the position of the spiral groove makes it difficult to apply pressure to the paper belt, thus preventing the liquid in that position from being squeezed out. As the squeeze roller rotates, it frequently changes the position of the spiral groove. In the area traversed by the spiral groove, the liquid in the paper belt is not squeezed out, keeping the paper belt moist and soft. In the non-groove area, a large amount of liquid in the paper belt is squeezed out. With the continuous rotation of the squeeze roller, the wet position on the paper belt changes frequently, keeping some areas of the paper belt slippery and resilient. This better disperses the tension on the paper belt and effectively prevents the large amount of water squeezed out during the squeezing process, which would cause a significant decrease in the tensile strength of the paper belt and make it prone to cracking at the edges.

[0013] Preferably, the cleaning assembly includes scrapers disposed on the right side of the outer wall of the rotating frame, and two spring reset rods are fixedly connected to the right side of the outer wall of each of the twelve scrapers, and two sliding holes are provided on the inner wall of each of the twelve rotating frames; The inner walls of the twenty-four sliding holes are all slidably connected to the outer walls of the twenty-four spring return rods, the left side of the outer walls of the twelve scrapers are all in contact with the outer walls of the twelve extrusion rollers, and the twenty-four spring return rods are all in a compressed state. When the squeeze roller rotates, its outer wall contacts the scraper, which removes debris from the surface of the squeeze roller. When the concave surface of the squeeze roller moves to the position of the scraper, the spring return rod, which was previously compressed, releases its restoring force, causing the scraper to return to contact the concave surface of the squeeze roller. When the convex surface of the squeeze roller contacts the scraper again, it squeezes the scraper again, causing the scraper to press against the spring return rod. This allows the spring return rod to accumulate restoring force, thus thoroughly removing debris from the surface of the squeeze roller. This effectively prevents the surface of the squeeze roller from being covered with a lot of debris from the waste liquid when it comes into contact with the paper tape, which would increase the surface area of ​​the squeeze roller and increase the squeezing force on the paper tape.

[0014] The present invention has the following beneficial effects: (1) When using this invention, the drive motor is started to drive the sprocket rod on the left side to rotate, so that the conveyor chain rotates and the paper belt moves. During the process of the conveyor chain conveying the paper belt, the edge of the paper belt is photographed in real time by the vision detector to monitor whether the paper belt is deviated. When the paper belt is deviated, the small motor will start to drive the correction roller frame to rotate, so that the correction roller frame tilts. Through the synchronization component and the squeezing component, the squeezing roller will descend to squeeze the paper belt, which will squeeze out the waste liquid adsorbed in the paper belt and make the paper belt fully contact the roller in the correction roller frame, increasing the friction between the paper belt and the roller in the correction roller frame, making it easier for the correction roller frame to adjust the moving direction of the paper belt. This solves the problem that the paper belt is easy to slip after it is wet, making it difficult for the correction roller frame to change the deviation direction of the paper belt, thereby quickly correcting the position of the paper belt.

[0015] (2) During the continuous conveying of the paper belt by the conveyor chain of the present invention, the extrusion roller is affected by the friction between the extrusion roller and the paper belt. The extrusion roller will rotate. During its rotation, the position of the spiral groove is difficult to apply extrusion force to the paper belt, so that the liquid at this position of the paper belt is not squeezed out, so that some areas of the paper belt will remain wet and slippery and tough, which can better disperse the tension on the paper belt. It effectively prevents the paper belt from being squeezed out in large quantities, which would cause the tensile strength of the paper belt to drop significantly and easily cause cracks at the edge of the paper belt.

[0016] (3) When the extrusion roller rotates, when the convex surface of the extrusion roller contacts the paper tape, it will apply a large extrusion force to the paper tape, so that the paper tape can fully contact the correction roller frame. As the extrusion roller continues to rotate, the convex surface of the extrusion roller will separate from the paper tape. At this time, the concave surface of the extrusion roller will contact the paper tape, and the extrusion force applied to the paper tape will be reduced, making the paper tape easier to move. This effectively prevents the continuous application of a large extrusion force to the paper tape. When the conveyor chain transports the paper tape, the paper tape will be subject to a large resistance between the extrusion roller and the correction roller frame. The paper tape may accumulate on the left side of the extrusion roller and wrinkles will appear, affecting the full contact between the paper tape and the correction roller frame.

[0017] (4) When the extrusion roller rotates, the outer wall of the extrusion roller will contact the scraper. The scraper removes the debris on the surface of the extrusion roller, which effectively prevents the extrusion roller from having a lot of debris in the waste liquid attached to its surface when it comes into contact with the paper tape. This would increase the surface area of ​​the extrusion roller and increase the extrusion pressure on the paper tape. In addition, the extrusion roller only contacts the paper tape when the paper tape is skewed, which effectively prevents the extrusion roller from extruding the paper tape for a long time, which would cause the paper tape to be continuously stretched and easily cause deformation of the paper tape edge.

[0021] 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.

[0022] Example 1, please refer to Figures 1-5 This invention relates to a machine vision-based dynamic deviation correction structure for magnetic filter belts, comprising a liquid storage frame 13 and a waste collection frame 15. A magnetic roller conveyor 14 is fixedly connected to the top right side of the liquid storage frame 13. Inclined baffles 17 are fixedly connected to both the front and back sides of the inner wall of the liquid storage frame 13. A protective cover 18 is fixedly connected to the top left side of the liquid storage frame 13. Two vision inspection instruments 16 are fixedly connected to the right side of the outer wall of the protective cover 18. The specific model of the vision inspection instrument 16 is TeledyneDALSA. The invention also includes: The conveying mechanism 1 is rotatably mounted on the inner wall of the liquid storage frame 13; Correction mechanism 2 is fixedly installed on the front and back of the inner wall of the liquid storage frame 13; The blocking mechanism 3 is fixedly installed on the top of the outer wall of the liquid storage frame 13; In use, the operator lays the paper strip flat on top of the liquid storage frame 13 using the conveying mechanism 1. As the paper strip moves, it comes into contact with the inclined baffle 17, causing the edges of the paper strip to bend. Figure 4 As shown in the position of G, the magnetic roller machine 14 is then started, and the waste liquid to be treated is discharged into the magnetic roller machine 14. The magnetic roller machine 14 adsorbs the metal fragments in the waste liquid. The waste liquid with adsorbed metal fragments will fall onto the top of the paper tape. The waste liquid will be filtered twice by permeating the paper tape. The filtered waste liquid will fall into the liquid storage box 13. The metal fragments adsorbed by the magnetic roller machine 14 will finally be discharged into the waste collection box 15 to collect the metal fragments.

[0023] Conveying mechanism 1 includes: Rotating assembly 11 is rotatably disposed on the inner wall of liquid storage frame 13; The drive assembly 12 is rotatably mounted on the inner wall of the protective cover 18.

[0024] Corrective agency 2 includes: The oscillation assembly 21 is fixedly installed on the front and back of the inner wall of the liquid storage frame 13 by fasteners. The fasteners include six mounting plates 211 fixedly connected to the front and back of the inner wall of the liquid storage frame 13, and small motors 212 are fixedly connected to the bottom of the outer wall of each of the twelve mounting plates 211. Synchronization component 22 is installed on the top of the outer wall of mounting plate 211.

[0025] The blocking mechanism 3 includes: The extrusion assembly 31 is fixedly installed on the top of the outer wall of the liquid storage frame 13; Clear component 32 is slidably set on the inner wall of synchronization component 22.

[0026] Example 2, please refer to Figures 2-8 The present invention is a dynamic deviation correction structure for magnetic filter belt based on machine vision. Based on Example 1, the rotating component 11 includes four rotating holes 1 opened in the inner wall of the liquid storage frame 13. The four rotating holes 1 are in pairs, and the inner walls of the two pairs of rotating holes 1 are rotatably connected to the sprocket rods 111. The inner wall of the liquid storage frame 13 is provided with a conveyor chain 112, and the outer walls of the two sprocket rods 111 are engaged with the inner wall of the conveyor chain 112.

[0027] The drive assembly 12 includes two rotating holes 2 opened in the inner wall of the protective cover 18, and a paper tape roller 121 is rotatably connected to the inner wall of the two rotating holes 2. A drive motor 122 is fixedly connected to the back of the outer wall of the liquid storage frame 13. The back of the sprocket rod 111 located on the left side is fixedly connected to the front of the output end of the drive motor 122; In use, the operator pulls the paper tape in the paper tape roller 121 to lay the paper tape on top of the conveyor chain 112. Then, the drive motor 122 is started to drive the sprocket rod 111 on the left side to rotate. The sprocket rod 111 drives the conveyor chain 112 to rotate, thereby moving the paper tape.

[0028] The sway assembly 21 includes twelve sway correction roller frames 213 disposed on the inner wall of the liquid storage frame 13, and the bottom of each of the twelve sway correction roller frames 213 is fixedly connected to the top of the output end of twelve small motors 212. The outer walls of the twelve correction roller frames 213 are rotatably connected to the inner walls of the twelve mounting plates 211. A connecting plate 214 is fixedly connected to the side of the twelve correction roller frames 213 near the inner wall of the liquid storage frame 13. The specific model of the small motor 212 is EC25. During the process of conveying the paper tape by the conveyor chain 112, the edge of the paper tape is photographed in real time by the vision inspection instrument 16 to monitor the movement of the paper tape and whether the paper tape is skewed. When the paper tape is skewed, the small motor 212 will start to drive the correction roller frame 213 to rotate, change the swing direction of the correction roller frame 213, tilt the correction roller frame 213, and change its contact angle with the paper tape.

[0029] The synchronization component 22 includes a rotating frame 221 set on the top of the outer wall of the mounting plate 211. Each of the twelve rotating frames 221 has two rotating holes 3 on its inner wall. The twenty-four rotating holes 3 are grouped in pairs. Each of the twelve groups of rotating holes 3 has a squeezing roller 222 rotatably connected to its inner wall. The twelve rotating frames 221 are slidably connected to the inner wall of the twelve connecting plates 214 on the side near the inner wall of the liquid storage frame 13, and the bottom of the twelve rotating frames 221 is fixedly connected to a spring rod 223. Each of the twelve connecting plates 214 has a sliding hole 1 on its inner wall, and the inner wall of each of the twelve sliding holes 1 is slidably connected to the outer wall of each of the twelve spring rods 223. When the correction roller frame 213 rotates, it will drive the connecting plate 214 to rotate, and the connecting plate 214 will drive the rotating frame 221 and the extrusion roller 222 to rotate.

[0030] The extrusion assembly 31 includes twelve arc-shaped inclined rings 311 fixedly connected to the top of the liquid storage frame 13, and ball rods 312 are fixedly connected to the top of the outer walls of the twelve rotating frames 221. The tops of the twelve spherical rods 312 are rotatably connected to the bottoms of the twelve arc-shaped inclined rings 311, and the outer walls of the twelve extrusion rollers 222 are all provided with spiral grooves 313; The rotating frame 221 drives the spherical rod 312 to contact the inclined surface of the arc-shaped inclined ring 311, causing the spherical rod 312 to be squeezed. This pushes the rotating frame 221, the squeeze roller 222, and the spring rod 223 to descend, causing the spring rod 223 to be squeezed and accumulate rebound force. The descending squeeze roller 222 will contact the paper tape, thereby squeezing the paper tape and squeezing out the waste liquid adsorbed in the paper tape. It will also make the paper tape fully contact the roller in the correction roller frame 213, increasing the friction between the paper tape and the roller in the correction roller frame 213. This makes it easier for the correction roller frame 213 to adjust the moving direction of the paper tape, solving the problem that the paper tape is prone to slipping after it is wet, making it difficult for the correction roller frame 213 to change the offset direction of the paper tape. This allows for quick correction of the position of the paper tape. During the continuous conveying of the paper belt by the conveyor chain 112, the squeeze roller 222 is affected by the friction between itself and the paper belt, causing the squeeze roller 222 to rotate. During its rotation, the position of the spiral groove 313 makes it difficult to apply pressure to the paper belt, thus preventing the liquid in that position from being squeezed out. As the squeeze roller 222 rotates, it frequently changes the position of the spiral groove 313. In the area traversed by the spiral groove 313, the liquid in the paper belt is not squeezed out, keeping the paper belt moist and soft. In the non-groove area, a large amount of liquid in the paper belt is squeezed out. As the squeeze roller 222 continues to rotate, the wet position on the paper belt changes frequently, keeping some areas of the paper belt slippery and resilient. This better disperses the tension on the paper belt and effectively prevents the large amount of water inside the paper belt from being squeezed out during the compression process, which would cause a significant decrease in the tensile strength of the paper belt and make it easy for cracks to appear at the edges of the paper belt.

[0031] The cleaning component 32 includes a scraper 321 disposed on the right side of the outer wall of the rotating frame 221. Two spring reset rods 322 are fixedly connected to the right side of the outer wall of each of the twelve scrapers 321. Two sliding holes are opened on the inner wall of each of the twelve rotating frames 221. The inner walls of the twenty-four sliding holes are all slidably connected to the outer walls of the twenty-four spring return rods 322, the left side of the outer walls of the twelve scrapers 321 are all in contact with the outer walls of the twelve extrusion rollers 222, and the twenty-four spring return rods 322 are all in a compressed state. When the squeeze roller 222 rotates, its outer wall contacts the scraper 321, which scrapes away debris from the surface of the squeeze roller 222. When the concave surface of the squeeze roller 222 moves to the position of the scraper 321, the spring return rod 322, which was previously compressed, releases its rebound force, causing the scraper 321 to return to contact the concave surface of the squeeze roller 222. When the convex surface of the squeeze roller 222 contacts the scraper 321 again, it will squeeze the scraper 321 again, causing the scraper 321 to squeeze the spring return rod 322. This allows the spring return rod 322 to accumulate rebound force, thereby effectively removing debris from the surface of the squeeze roller 222. This effectively prevents the surface of the squeeze roller 222 from being covered with a lot of debris from the waste liquid when it comes into contact with the paper tape, which would increase the surface area of ​​the squeeze roller 222 and increase the squeezing force on the paper tape.

[0032] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0033] A specific application of this embodiment is as follows: When using this invention, the operator pulls the paper tape in the paper tape roller 121 to lay the paper tape on top of the conveyor chain 112. Then, the drive motor 122 is started to drive the sprocket rod 111 on the left side to rotate. The sprocket rod 111 drives the conveyor chain 112 to rotate, thereby conveying the paper tape. During the movement, the paper tape will come into contact with the inclined baffle 17, causing the edge of the paper tape to bend, such as... Figure 4 As shown in the position of G, then start the magnetic roller machine 14, and discharge the waste liquid to be treated into the magnetic roller machine 14. The magnetic roller machine 14 adsorbs the metal fragments in the waste liquid. The waste liquid with adsorbed metal fragments will fall on the top of the paper tape. The waste liquid will be filtered twice by permeating the paper tape. The filtered waste liquid will fall into the liquid storage box 13. The metal fragments adsorbed by the magnetic roller machine 14 will finally be discharged into the waste collection box 15 to collect the metal fragments. During the conveyor chain 112 conveys the paper tape, the edge of the paper tape is photographed in real time by the vision inspection instrument 16 to monitor the movement of the paper tape and whether the paper tape is skewed. When the paper tape is skewed, the small motor 212 will start to drive the correction roller frame 213 to rotate, change the swing direction of the correction roller frame 213, and tilt the correction roller frame 213. When the correction roller frame 213 rotates, it will drive the connecting plate 214 to rotate, and through the connecting plate 214, it will drive the rotating frame 221 and the squeezing roller 222 to rotate. The rotating frame 221 drives the spherical rod 312 to contact the inclined surface of the arc-shaped inclined ring 311, causing the spherical rod 312 to be squeezed. This pushes the rotating frame 221, the squeeze roller 222, and the spring rod 223 to descend, causing the spring rod 223 to be squeezed and accumulate rebound force. The descending squeeze roller 222 will contact the paper tape, thereby squeezing the paper tape and squeezing out the waste liquid adsorbed in the paper tape. It will also make the paper tape fully contact the roller in the correction roller frame 213, increasing the friction between the paper tape and the roller in the correction roller frame 213. This makes it easier for the correction roller frame 213 to adjust the moving direction of the paper tape, solving the problem that the paper tape is prone to slipping after it is wet, making it difficult for the correction roller frame 213 to change the offset direction of the paper tape. This allows for quick correction of the paper tape's position. When the paper tape deviates, the sway angle of the correction roller frame 213 is changed. At this time, the axis of the roller in the correction roller frame 213 is no longer perpendicular to the direction of paper tape movement, but forms an angle. The paper tape still moves to the right under the conveyor chain 112. Due to this angle, the direction of the friction force at the contact point between the paper tape and the surface of the correction roller frame 213 will change, forming a lateral friction force. Under the action of this lateral friction force, the paper tape moves forward and moves laterally smoothly, eventually returning to the center position, thus completing the correction of the paper tape. Secondly, during the continuous conveying of the paper belt by the conveyor chain 112, the squeeze roller 222 is affected by the friction between itself and the paper belt, causing the squeeze roller 222 to rotate. During its rotation, the position of the spiral groove 313 makes it difficult to apply pressure to the paper belt, thus preventing the liquid in that position of the paper belt from being squeezed out. As the squeeze roller 222 rotates, it frequently changes the position of the spiral groove 313. In the area traversed by the spiral groove 313, the liquid in the paper belt is not squeezed out, keeping the paper belt moist and soft. In the non-groove area, a large amount of liquid in the paper belt is squeezed out. As the squeeze roller 222 continues to rotate, the wet position on the paper belt will frequently switch, keeping some areas of the paper belt wet and flexible, which can better disperse the tension on the paper belt and effectively prevent the large amount of water inside the paper belt from being squeezed out during the compression process, which would cause a significant decrease in the tensile strength of the paper belt and make it easy for cracks to appear on the edge of the paper belt. Secondly, when the squeeze roller 222 rotates, when the convex surface of the squeeze roller 222 contacts the paper strip, such as Figure 8 As shown in the position of H, a large squeezing force is applied to the paper tape, allowing the paper tape to fully contact the corrective roller frame 213. As the squeezing roller 222 continues to rotate, the convex surface of the squeezing roller 222 will separate from the paper tape. At this time, the concave surface of the squeezing roller 222 will contact the paper tape, as shown in the image. Figure 8 As shown in position I, the squeezing force applied to the paper tape will be reduced, making the paper tape easier to move and effectively preventing the continuous application of large squeezing force to the paper tape. When the conveyor chain 112 conveys the paper tape, the paper tape will experience greater resistance between the squeezing roller 222 and the correction roller frame 213. The paper tape may accumulate on the left side of the squeezing roller 222 and wrinkle, affecting the full contact between the paper tape and the correction roller frame 213. Secondly, when the squeeze roller 222 rotates, its outer wall contacts the scraper 321, which scrapes away debris from the surface of the squeeze roller 222. When the concave surface of the squeeze roller 222 moves to the position of the scraper 321, the spring return rod 322, which was previously compressed, releases its restoring force, causing the scraper 321 to return to its original position and contact the concave surface of the squeeze roller 222. When the convex surface of the squeeze roller 222 contacts the scraper 321 again, it will squeeze the scraper 321 again, causing the scraper 321 to squeeze the spring return rod 322. This allows the spring return rod 322 to accumulate restoring force, thereby thoroughly removing debris from the surface of the squeeze roller 222 and effectively preventing the squeeze roller 222 from colliding with the paper tape. When in contact, a lot of debris from the waste liquid will adhere to its surface, increasing the surface area of ​​the squeeze roller 222 and increasing the squeezing force on the paper tape. In addition, when the image captured by the vision inspection instrument 16 shows that the paper tape is moving in a straight line, the small motor 212 will start again to drive the correction roller frame 213 to rotate, so that the correction roller frame 213 and the rotating frame 221 return to their original positions, and drive the ball rod 312 to move again to the concave position of the arc-shaped inclined ring 311. The rebound force of the spring rod 223 will be released, causing the squeeze roller 222 to rise and separate from the paper tape. Thus, the squeeze roller 222 will only contact the paper tape when the paper tape is skewed, effectively preventing the squeeze roller 222 from squeezing the paper tape for a long time, which would cause the paper tape to be continuously stretched and easily cause deformation of the paper tape edge.
