Description

Technical Field

[0001] This application belongs to the field of coating machine technology, specifically an automatic correction and winding device for a coating machine. Background Technology

[0002] The automatic web guiding system uses sensors to detect the position of the web edge, the controller analyzes the signal and issues a web guiding command, and the electric drive executes the adjustment action, thereby ensuring precise control of the web during the coating process, avoiding deviation and misalignment.

[0003] Existing automatic deviation correction and winding devices for coating machines require operators to manually judge the deviation distance and then manually move the winding roller to correct the deviation. The overall winding efficiency is slow and it is easy to cause safety accidents. Now, an automatic deviation correction and winding device for coating machines is provided that can automatically correct the deviation and rewind after detecting the winding deviation. Utility Model Content

[0004] The purpose of this application is to provide an automatic deviation correction and winding device for coating machines, which addresses the problem that existing automatic deviation correction and winding devices for coating machines require operators to manually judge the deviation distance and then manually move the winding roller to correct the deviation, resulting in slow overall winding efficiency and a high risk of safety accidents.

[0005] The technical solution adopted in this application is as follows: an automatic correction and winding device for a coating machine, wherein a winding frame is fixedly installed on the upper surface of the base, a threaded hole is opened on one side surface of the winding frame, a fixing bolt is movably connected to the surface of the threaded hole, a fixing block is fixedly installed on the surface of the fixing bolt, a limit block is movably connected to the surface of the fixing block, a through hole is opened on the upper surface of the limit block, a first driven eccentric gear is movably inserted into the surface of the through hole, a driving eccentric gear is movably connected to the surface of the first driven eccentric gear, a second driven eccentric gear is movably connected to the surface of the driving eccentric gear, a driving shaft is fixedly installed on the upper surface of the driving shaft, a micro motor is fixedly installed on the upper surface of the driving shaft, and a magnetic suction plate is fixedly installed on the side surface of the limit block away from the fixing block.

[0006] By adopting the above technical solution, the device can activate the micro motor by using the image obtained by the vision inspection instrument. The micro motor converts electrical energy into mechanical energy, driving the active eccentric gear to rotate. The first and second driven eccentric gears mesh with the active eccentric gear. The rotation direction of the active eccentric gear moves the limiting block back and forth. The center of the eccentric gear does not coincide with the geometric center of the gear, causing a radial displacement when the gear rotates. This displacement can be converted into linear motion of the fixed block. The magnetic plate has a certain magnetism and can move the winding roller left and right, thereby correcting the material deviation and winding it up.

[0007] In a preferred embodiment, a rotating rod is movably inserted into the surface of the winding frame, and a winding roller is fixedly mounted on the surface of the rotating rod.

[0008] By adopting the above technical solution, the rotating rod drives the take-up roller to rotate during the rotation process, thereby taking up the material on the coating machine. Under the action of the correction device, the material is taken up more neatly.

[0009] In a preferred embodiment, a driven gear is fixedly mounted on the surface of the rotating rod, a driving gear is movably connected to the surface of the driven gear, a servo motor is fixedly mounted on the surface of the driving gear, and a motor support plate is fixedly mounted on the surface of the winding frame adjacent to the servo motor.

[0010] By adopting the above technical solution, when the operator turns on the servo motor to wind up the material of the coating machine, the servo motor rotates the drive gear. The drive gear meshes with the driven gear, and the driven gear and the servo motor rotate in the same direction to automatically rotate the winding roller, thereby improving processing efficiency.

[0011] In a preferred embodiment, a control panel is fixedly mounted on the surface of the winding rack.

[0012] By adopting the above technical solution, the control panel can process the images detected by the vision inspection instrument, making it convenient for users to perform corrections and improving the overall correction quality and efficiency.

[0013] In a preferred embodiment, a fixing frame is fixedly installed on the upper surface of the base, a placement roller is movably installed on the surface of the fixing frame, and a support leg is fixedly installed on the lower surface of the base.

[0014] By adopting the above technical solution, the placement roller rotates automatically under the drive of the drive motor, which can move the fabric collected on the placement roller to the take-up roller for more regular winding, making it convenient for subsequent storage and use.

[0015] In a preferred embodiment, a drive motor is fixedly mounted on one side surface of the placement roller.

[0016] By adopting the above technical solution, the drive motor converts mechanical energy into electrical energy to drive the placement roller to rotate, reducing manual intervention and improving the automation level of the overall device. The material already collected by the placement roller is automatically collected into the winding roller by the automatic correction device, resulting in a more regular winding.

[0017] In a preferred embodiment, a U-shaped frame is fixedly mounted on the surface of the winding frame, and a vision inspection instrument is fixedly mounted on the lower surface of the U-shaped frame.

[0018] By adopting the above technical solution, the vision inspection instrument can capture and process images in real time and send them to the control panel, which makes it convenient for users to keep track of the material winding status in real time, and allows operators to use the image of the vision inspection instrument to perform correction processing on the material.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: In this application, the device activates a micro motor based on an image obtained from a vision inspection instrument. The micro motor converts electrical energy into mechanical energy, driving the active eccentric gear to rotate. The first and second driven eccentric gears mesh with the active eccentric gear. The rotation direction of the active eccentric gear moves the limiting block back and forth. Since the center of the eccentric gear does not coincide with the geometric center of the gear, a radial displacement occurs during rotation. This displacement is converted into linear motion of the fixed block. The magnetic plate, possessing a certain magnetism, moves the take-up roller left and right, thereby correcting the material's deviation and winding it up. During rotation, the rotating rod drives the take-up roller to rotate, thus winding up the material on the coating machine. Under the action of the deviation correction device, the material is wound up relatively neatly. Attached Figure Description

[0024] An automatic correction and winding device for a coating machine includes a winding frame 10 fixedly mounted on the upper surface of a base 1. A threaded hole is formed on one side surface of the winding frame 10, and a fixing bolt 22 is movably connected to the surface of the threaded hole. A fixing block 23 is fixedly mounted on the surface of the fixing bolt 22, and a limit block 24 is movably connected to the surface of the fixing block 23. A through hole is formed on the upper surface of the limit block 24, and a first driven eccentric gear 17 is movably inserted into the surface of the through hole. A driving eccentric gear 20 is movably connected to the surface of the first driven eccentric gear 17, and a second driven eccentric gear 21 is movably connected to the surface of the driving eccentric gear 20. A drive shaft 18 is fixedly mounted on the upper surface of the drive shaft 18, and a micro motor 19 is fixedly mounted on the upper surface of the drive shaft 18. A magnetic suction plate 16 is fixedly mounted on the side surface of the limit block 24 away from the fixing block 23.

[0025] When in use, the image obtained by the vision inspection instrument 12 can activate the micro motor 19. The micro motor 19 converts electrical energy into mechanical energy, driving the active eccentric gear 20 to rotate. The first driven eccentric gear 17 and the second driven eccentric gear 21 mesh with the active eccentric gear 20. The rotation direction of the active eccentric gear 20 moves the limiting block 24 back and forth. The center of the eccentric gear does not coincide with the geometric center of the gear, causing the gear to generate a radial displacement when rotating. This displacement can be converted into linear motion of the fixed block. The magnetic suction plate 16 has a certain magnetism and can move the winding roller 11 left and right, thereby correcting the material deviation and winding it up.

[0026] A rotating rod 4 is movably inserted into the surface of the winding frame 10, and a winding roller 11 is fixedly mounted on the surface of the rotating rod 4. During the rotation of the rotating rod 4, the winding roller 11 is driven to rotate, thereby winding up the material on the coating machine. Under the action of the correction device, the winding of the material is relatively neat.

[0027] A driven gear 5 is fixedly mounted on the surface of the rotating rod 4. A driving gear 7 is movably connected to the surface of the driven gear 5. A servo motor 3 is fixedly mounted on the surface of the driving gear 7. A motor support plate 2 is fixedly mounted on the surface of the take-up frame 10 adjacent to the servo motor 3. When the operator turns on the servo motor 3 to take up the material of the coating machine, the servo motor 3 rotates the driving gear 7. The driving gear 7 meshes with the driven gear 5, and the driven gear 5 and the servo motor 3 rotate in the same direction to automatically rotate the take-up roller 11, thereby improving processing efficiency.

[0028] A control panel 8 is fixedly mounted on the surface of the winding rack 10. The control panel 8 can process the images detected by the vision inspection instrument 12, making it convenient for users to perform corrections and improving the overall correction quality and efficiency.

[0029] A mounting bracket 9 is fixedly installed on the upper surface of the base 1. A placement roller 13 is movably mounted on the surface of the mounting bracket 9. A drive motor 14 is fixedly installed on one side of the placement roller 13. Driven by the drive motor 14, the placement roller 13 rotates automatically, which can move the fabric collected on the placement roller 13 to the take-up roller 11 for more regular winding, which is convenient for subsequent storage and use.

[0030] A drive motor 14 is fixedly installed on one side surface of the placement roller 13, and a support leg 15 is fixedly installed on the lower surface of the base 1. The drive motor 14 converts mechanical energy into electrical energy to drive the placement roller 13 to rotate, reducing manual intervention and improving the automation level of the overall device. The material already collected by the placement roller 13 is automatically collected into the winding roller 11 by the automatic correction device, resulting in a more regular winding.

[0031] A U-shaped frame 6 is fixedly installed on the surface of the winding rack 10, and a vision inspection instrument 12 is fixedly installed on the lower surface of the U-shaped frame 6. The vision inspection instrument 12 can capture and process images in real time and send them to the control panel 8, so that users can keep track of the winding status of the material in real time, and operators can use the image of the vision inspection instrument 12 to perform correction processing on the material using the correction device.

[0032] The implementation principle of an embodiment of an automatic web-correcting and winding device for a coating machine according to this application is as follows: When in use, the image obtained by the vision inspection instrument 12 activates the micro motor 19, which converts electrical energy into mechanical energy, driving the active eccentric gear 20 to rotate. The first driven eccentric gear 17 and the second driven eccentric gear 21 mesh with the active eccentric gear 20. The rotation direction of the active eccentric gear 20 moves the limiting block 24 back and forth. The center of the eccentric gear does not coincide with the geometric center of the gear, causing a radial displacement when the gear rotates. This displacement can be converted into linear motion of the fixed block. The magnetic suction plate 16 has a certain magnetism and can move the take-up roller 11 left and right, thereby correcting the material deviation and taking it up. During the rotation of the rotating rod 4, the take-up roller 11 rotates, thereby taking up the material on the coating machine. Under the action of the deviation correction device, the material is taken up more neatly.

[0033] When the operator turns on the servo motor 3 to wind up the material on the coating machine, the servo motor 3 rotates the drive gear 7. The drive gear 7 meshes with the driven gear 5, and the driven gear 5 and the servo motor 3 rotate in the same direction, automatically rotating the winding roller 11, thus improving processing efficiency. The vision inspection instrument 12 can capture and process images in real time and send them to the control panel 8, allowing users to monitor the winding status of the material in real time. This also allows operators to use the images from the vision inspection instrument 12 to apply a correction device to correct the material's deviation.
