Description

Technical Field

[0001] This utility model relates to the field of tension straightening machine technology, and more specifically, to an automatic film-coating tension straightening machine unit. Background Technology

[0002] The development of a new type of automatic coating and straightening machine is an important technological advancement in the field of metal processing. It is mainly used to improve the surface quality and mechanical properties of metal strips. This equipment is commonly used in the production process of metal strips such as steel and aluminum. Through stretching and straightening, the metal strips achieve the required flatness and surface finish.

[0003] A search revealed that Chinese patent CN218361427U discloses a tension leveling machine. This machine addresses the problem that existing tension leveling machines primarily rely on motors for lifting and lowering, sometimes resulting in asynchronous movement between the two ends, causing uneven force distribution. Furthermore, the motors are prone to damage, making replacement difficult and manual adjustment impossible, thus reducing material production efficiency. The new machine allows for manual driving, enabling the upper and lower bending rollers to move simultaneously closer or further apart, allowing for more precise adjustment of the height balance on both sides and ensuring more uniform force distribution on the steel plate.

[0004] Most traditional equipment has a fixed spacing between its drive rollers, which is difficult to adjust flexibly to adapt to changes in strip width. When faced with processing tasks for strips of different widths, it is often necessary to replace the entire drive roller device. Once the strip deviates, it is difficult to detect and correct it in time, causing the strip to run continuously on the wrong path, which greatly affects the straightening quality of the strip and leads to an increase in the scrap rate of the strip. Utility Model Content

[0005] In order to overcome the problems and defects in the prior art, this utility model provides an automatic film coating and straightening machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic film coating and straightening machine unit, including a base plate, two vertical plates fixedly connected to the top of the base plate, a straightening roller installed between the two vertical plates, a movable plate slidably connected to the top of the base plate, and a first fixed plate fixedly connected to the top of the base plate away from the movable plate.

[0007] Both the movable plate and the first fixed plate are fixedly connected to the top of a side plate. A first motor is fixedly installed on one side of the side plate. A transmission roller is fixedly connected to the output end of the first motor. An adjustment mechanism is provided between the unit base plate and the movable plate.

[0008] Preferably, the adjustment mechanism includes a fixing groove, which is formed inside the unit base plate. A second motor is fixedly installed on the rear side of the unit base plate, and a threaded rod is fixedly connected to the output end of the second motor. A through groove is formed on the top surface of the unit base plate.

[0009] Preferably, a threaded sleeve is threaded to the outer side of the threaded rod, and a connecting slide plate is fixedly connected to the top of the threaded sleeve. The connecting slide plate is slidably connected to the through groove.

[0010] Preferably, a microcontroller is fixedly installed on the front side of the upright plate, a connecting plate is fixedly connected to one side of the upright plate, a displacement sensor is fixedly installed on the front side of the connecting plate, and the microcontroller is electrically connected to the displacement sensor, the first motor, and the second motor.

[0011] Preferably, a limiting mechanism is provided on one side of the connecting plate. The limiting mechanism includes a second fixing plate, which is fixed to one side of the connecting plate. A sliding hole is provided on the front surface of the second fixing plate.

[0012] Preferably, a movable rod is slidably connected inside the sliding hole, and a spring is sleeved on the outside of the movable rod. One end of the spring is fixedly connected to the second fixed plate, and a baffle is fixedly connected to the other end of the spring. The baffle is fixedly connected to the movable rod.

[0013] Preferably, a fixing block is fixedly connected to one end of the moving rod, a rotating shaft is rotatably connected inside the fixing block, and a limiting wheel is fixedly sleeved on the outside of the rotating shaft.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By setting up an adjustment mechanism, the second motor, threaded rod, threaded sleeve, and connecting slide work together to precisely adjust the position of the moving plate. This allows the spacing between the transmission rollers to be flexibly adjusted according to the width of the strip or specific process requirements, enhancing the equipment's adaptability to different specifications of strip. The displacement sensor captures the strip offset signal, which the microcontroller can quickly analyze and process, and issue instructions to the first and second motors. By adjusting the speed difference of the transmission rollers or the position of the moving plate, the running trajectory of the strip is corrected in a timely manner, ensuring that the strip always moves on the correct path. This effectively guarantees the straightening quality of the strip, reduces the scrap rate, and improves production efficiency.

[0016] 2. By setting up a limit mechanism, the strip material is provided with additional limit protection through the synergistic action of components such as limit wheels, moving rods, and springs. When the strip material deviates and touches the limit wheel, the limit wheel rotates and compresses the spring. The elastic force generated by the spring buffers and corrects the strip material deviation, preventing excessive deviation and production failures. This further improves the stability and reliability of the equipment operation and extends the service life of the equipment. Attached Figure Description

[0025] Side plates 6 are fixedly connected to the top of both the movable plate 4 and the first fixed plate 5. A first motor 7 is fixedly installed on one side of the side plate 6. A transmission roller 8 is fixedly connected to the output end of the first motor 7. An adjustment mechanism is provided between the unit base plate 1 and the movable plate 4.

[0026] As attached Figure 1 , 2 As shown in Figure 4, the adjustment mechanism includes a fixed groove 9, which is located inside the unit base plate 1. A second motor 10 is fixedly installed on the rear side of the unit base plate 1. A threaded rod 11 is fixedly connected to the output end of the second motor 10. A through groove 14 is provided on the top surface of the unit base plate 1. A threaded sleeve 13 is threadedly connected to the outer side of the threaded rod 11. A connecting slide plate 12 is fixedly connected to the top of the threaded sleeve 13. The connecting slide plate 12 and the through groove 14 are slidably connected, so that the position of the transmission roller 8 can be adjusted, thereby adjusting the position of the strip and preventing the strip position from shifting.

[0027] As attached Figure 1-4 As shown, a microcontroller 15 is fixedly installed on the front side of the upright plate 2, and a connecting plate 16 is fixedly connected to one side of the upright plate 2. A displacement sensor 17 is fixedly installed on the front side of the connecting plate 16. The microcontroller 15 is electrically connected to the displacement sensor 17, the first motor 7, and the second motor 10, so as to facilitate the monitoring of the strip offset through the displacement sensor 17. The microcontroller 15 controls and adjusts the speed difference of the transmission roller 8 or the position of the moving plate 4 to correct the running trajectory of the strip in a timely manner.

[0028] As attached Figure 1-5 As shown, a limiting mechanism is provided on one side of the connecting plate 16. The limiting mechanism includes a second fixed plate 18, which is fixed to one side of the connecting plate 16. A sliding hole 25 is provided on the front surface of the second fixed plate 18. A moving rod 19 is slidably connected inside the sliding hole 25. A spring 20 is sleeved on the outside of the moving rod 19. One end of the spring 20 is fixedly connected to the second fixed plate 18, and the other end of the spring 20 is fixedly connected to a baffle 21. The baffle 21 is fixedly connected to the moving rod 19. A fixed block 22 is fixedly connected to one end of the moving rod 19. A rotating shaft 23 is rotatably connected inside the fixed block 22. A limiting wheel 24 is fixedly sleeved on the outside of the rotating shaft 23, so that the limiting wheel 24 can be used to straighten strips of different widths through the spring 20.

[0029] The working principle of this utility model is as follows: The base plate 1 of the unit serves as the basic support component of the entire unit. Two vertical plates 2 are fixedly connected to it. The tension rollers 3 installed between the two vertical plates 2 act as bending rollers and straightening rollers. After the strip enters the unit, under the action of the tension rollers 3, the strip is continuously bent and straightened through the combination of multiple tension rollers 3. The tension rollers 3 at different positions and angles cause the strip to bend and deform in different directions, and then straighten it to a flat state, thereby effectively eliminating defects such as wavy edges, edge waviness, and sickle bends of the strip.

[0030] A movable plate 4 is slidably connected to the top of the unit base plate 1, and a first fixed plate 5 is fixedly connected to the side away from the movable plate 4. Side plates 6 are fixedly connected to the top of both the movable plate 4 and the first fixed plate 5. A first motor 7, fixedly installed on one side of the side plate 6, drives a transmission roller 8 to rotate after starting. The transmission roller 8 provides power for the movement of the strip, enabling the strip to be smoothly transported within the unit. An adjustment mechanism is provided between the unit base plate 1 and the movable plate 4 to adjust the position of the movable plate 4 to accommodate strips of different widths or process requirements. In the adjustment mechanism, a second motor 10 fixedly installed on the rear side of the unit base plate 1 starts, and its output drives a threaded rod 11 to rotate. Since a threaded sleeve 13 is threadedly connected to the outer side of the threaded rod 11, and the connecting slide plate 12 fixedly connected to the top of the threaded sleeve 13 is slidably connected to the through groove 14 opened on the top surface of the unit base plate 1, the rotation of the threaded rod 11 will cause the threaded sleeve 13 to move along the threaded rod 11. 1. The linear motion drives the connecting slide plate 12 to slide within the through groove 14, ultimately enabling the moving plate 4 to slide on top of the unit base plate 1, adjusting the spacing between the transmission rollers 8. The single-chip microcomputer 15 fixedly installed on the front side of the upright plate 2 serves as the control core. The displacement sensor 17 fixedly installed on the front side of the connecting plate 16 fixedly connected to one side of the upright plate 2 monitors the offset of the strip in real time. The displacement sensor 17 transmits the detected strip offset signal to the single-chip microcomputer 15. The single-chip microcomputer 15 analyzes and processes the signal. If the strip deviates, the single-chip microcomputer 15 will send control signals to the first motor 7 and the second motor 10 according to the offset. When the strip deviates to the left, the single-chip microcomputer 15 controls the first motor 7 to adjust the speed difference of the transmission rollers 8, or controls the second motor 10 to adjust the position of the moving plate 4, thereby adjusting the position of the guide roller or tension roller to keep the strip on the correct path, ensuring the straightening quality and production efficiency of the strip.

[0031] A limiting mechanism is provided on one side of the connecting plate 16 to assist in limiting the strip and prevent excessive deviation of the strip. In the limiting mechanism, the second fixing plate 18 is fixed to one side of the connecting plate 16. A sliding rod 19 is slidably connected inside the sliding hole 25 opened on its front surface. A spring 20 is sleeved on the outside of the moving rod 19. One end of the spring 20 is fixedly connected to the second fixing plate 18, and the other end is fixedly connected to the baffle 21. The baffle 21 is fixedly connected to the moving rod 19. A rotating shaft 23 is rotatably connected inside the fixing block 22 fixedly connected to one end of the moving rod 19. A limiting wheel 24 is fixedly sleeved on the outside of the rotating shaft 23. When the strip deviates and touches the limiting wheel 24, the limiting wheel 24 will rotate under the action of the rotating shaft 23. At the same time, the moving rod 19 compresses the spring 20. The elastic force generated by the spring 20 can buffer and correct the deviation of the strip, further ensuring that the strip runs on the correct path.

[0032] In conclusion, the above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
