Description

Technical Field

[0001] The utility model relates to the technical field of steel strip winding, in particular to automatic winding equipment for heat-treated steel strips. Background Art

[0002] Heat treatment is a process that alters the internal structure of metals through heating, insulation, and cooling to achieve desired properties. For steel strip, heat treatment can significantly improve key properties such as hardness, strength, toughness, and corrosion resistance. Heat-treated steel strip winding equipment ensures the flatness and integrity of the strip after heat treatment. It also effectively prevents deformation or damage during the winding process by precisely controlling winding tension and speed. The application of automatic heat-treated steel strip winding equipment promotes the optimization of heat treatment processes and improves production efficiency.

[0003] The existing Chinese patent with announcement number CN214610542U discloses a dual-shaft stainless steel strip winding device, including a steel frame bracket, a groove is provided at one end of the steel frame bracket, a drive motor is fixedly installed on the inner side of the groove, guide rails are provided on both sides of the drive motor, a telescopic rod is fixed at one end of the drive motor, a base is fixed at one end of the telescopic rod, slide grooves are fixed on both sides of the base, and a winding machine operating table is fixed on the top of the base.

[0004] Although the above scheme can reduce time waste, improve work efficiency and speed up production, the winding equipment lacks tension detection. During the steel strip winding process, insufficient tension may cause the steel strip to relax during winding, forming wrinkles or poor winding, while excessive tension may cause the steel strip to overstretch, resulting in deformation or damage. Both will lead to uneven heating time during heat treatment. Some parts may be overheated, while other parts may be underheated, resulting in substandard thermal performance. At the same time, the winding device also lacks a correction function, which may cause the winding position to offset and affect the winding effect. Therefore, it does not meet existing needs. In this regard, we have proposed an automatic winding device for heat-treated steel strips. Utility Model Content

[0005] The purpose of the present invention is to provide an automatic winding device for heat-treated steel strips to solve the problems in the above-mentioned background technology that the automatic winding device for steel strips lacks tension detection affecting thermal performance and the steel strips are easily offset during winding, affecting the winding effect.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an automatic winding device for heat-treated steel strips, comprising a main body, a winding drum being provided on one side of the main body;

[0007] It also includes a pressure roller, which is arranged on the upper side of the interior of the main body, and a fixed seat is provided above the pressure roller, and the fixed seat and the pressure roller are connected via a second connecting shaft, the second connecting shaft is rotatably connected to the fixed seat, and the second connecting shaft is fixedly connected to the pressure roller;

[0008] It also includes a pressure sensor, which is arranged on the upper end of the pressure roller, and the upper end of the pressure sensor is provided with a connecting plate;

[0009] The utility model also includes infrared generators, which are arranged on the front and rear sides of the upper end of the main body, and four infrared generators are evenly distributed on each side.

[0010] Preferably, a PLC controller is installed at the front end of the main body.

[0011] Preferably, four infrared receivers are installed on the front and rear sides of the lower end of the main body at equal intervals, and the output ends of the infrared receivers are electrically connected to the input ends of the PLC controller.

[0012] Preferably, an audible and visual alarm is installed at the upper end of the main body, and the input end of the audible and visual alarm is electrically connected to the output end of the PLC controller.

[0013] Preferably, three equally spaced slides are provided on one side of the upper end of the main body, and a sliding rod is provided inside the slide. One end of the sliding rod extends to the outside of the slide, and the sliding rod slides with the slide. The end of the sliding rod located outside the slide is connected to the connecting plate, and the end of the sliding rod located inside the slide is connected to the slide through a reset spring.

[0014] Preferably, a first connecting shaft is provided at the rear end of the winding drum, a motor is provided behind the first connecting shaft, a torque sensor is provided at the output end of the motor through a coupling, and the torque sensor and the first connecting shaft are connected through a coupling.

[0015] Preferably, two guide auxiliary rollers are provided on one side of the interior of the main body, and both guide auxiliary rollers are rotatably connected to the main body.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The utility model is provided with a pressure roller on one side of the upper end of the main body, and the pressure roller is rotatably connected to the fixed seat by a second connecting shaft. When the steel belt passes and exerts force on the pressure roller, the roller moves up, causing the slide rod to slide into the slide cylinder and compress the spring, thereby increasing the pressure value detected by the pressure sensor. If the steel belt is loose, its force on the pressure roller is reduced, resulting in a reduction in the compression of the spring, thereby reducing the pressure value detected by the pressure sensor. The pressure sensor can be connected to an external display device for real-time monitoring of the tension of the steel belt, so that the pressure change when the steel belt is wound can be intuitively known to avoid affecting the effect of the heat treatment.

[0018] 2. The utility model is provided with infrared receivers on the front and rear sides of the lower end of the main body, and an infrared generator is provided above the infrared receiver. When the infrared generator is started, infrared rays can be generated and received by the infrared receiver. During the normal winding process, the infrared rays can be smoothly transmitted between the generator and the receiver without being blocked. When the steel strip deviates during winding, the deviated part of the steel strip will block the infrared rays, causing the infrared receiver to be unable to receive the complete infrared signal. At this time, the infrared receiver will immediately recognize this change and send a signal to the PLC controller. After processing, the PLC controller will activate the sound and light alarm to remind the operator to come and deal with the deviation problem of the steel strip to avoid affecting the winding effect.

[0019] 3. The utility model connects a torque sensor to the output end of the motor through a coupling. When the motor is started to rotate the winding drum to reel in the steel strip, the torque sensor detects the composite amount of force and torque by measuring the torque on the first connecting shaft. The torque sensor sends the detected torque data to the PLC controller. The operator can set the standard speed of the first connecting shaft through the PLC controller. The PLC controller receives the data from the torque sensor and compares and judges according to the preset standard value to adjust the motor speed and achieve a uniform force-rewinding effect.

[0031] During use, the steel strip passes through the guide auxiliary roller 5 and is wound on the winding drum 4. When the motor 15 is started, the steel strip is evenly wound. The tension detection mechanism composed of the pressure roller 8 and the return spring 13 feeds back the steel strip tension to the display device in real time through the pressure sensor 10 to ensure tension stability. The infrared generator 6 and the infrared receiver 7 are combined to detect the deviation of the steel strip. Once deviated, the sound and light alarm 3 immediately alarms. The torque sensor 16 monitors the torque change of the first connecting shaft 17 in real time, and adjusts the speed of the motor 15 through the PLC controller 2 to maintain the uniformity and tightness of the steel strip winding to ensure product quality.

[0034] See also Figure 1 and Figure 2 , an audible and visual alarm 3 is installed on the upper end of the main body 1, and the input end of the audible and visual alarm 3 is electrically connected to the output end of the PLC controller 2. Once the steel strip is deviated, the audible and visual alarm 3 can immediately send out an audible and visual signal to remind the operator to take timely measures to avoid the deviation of the steel strip winding;

[0035] See also Figure 4 and Figure 5 , three equally spaced slides 11 are provided on one side of the upper end of the main body 1, and slide rods 12 are provided inside the slides 11.

[0036] See also Figure 3 A first connecting shaft 17 is provided at the rear end of the winding drum 4, and a motor 15 is provided behind the first connecting shaft 17. A torque sensor 16 is provided at the output end of the motor 15 through a coupling, and the torque sensor 16 and the first connecting shaft 17 are connected to each other through a coupling. Through the data feedback of the torque sensor 16, the PLC controller 2 can adjust the speed and output torque of the motor 15 in real time to ensure the stability and uniformity of the steel strip during the winding process;

[0037] See also Figure 2 and Figure 3 Two guide auxiliary rollers 5 are provided on one side of the interior of the main body 1, and the guide auxiliary rollers 5 are rotatably connected to the main body 1. The two guide auxiliary rollers 5 can help the steel strip to smoothly enter the winding drum 4 for winding, which can improve the efficiency and stability of the steel strip winding and reduce the problem of steel strip jamming.

[0038] Working principle: When in use, pass the steel strip between the two guide auxiliary rollers 5 and connect it to the winding drum 4, start the motor 15 to reel the steel strip, at this time the pressure roller 8 will be located at the upper end of the steel strip, the pressure roller 8 will make the slide bar 12 slide into the interior of the slide drum 11, the movement of the slide bar 12 will squeeze the reset spring 13, as the steel strip continues to reel, if the steel strip maintains appropriate tension, the pressure roller 8 will remain in a relatively stable position, the compression amount of the reset spring 13 will also be maintained within a reasonable range, at this time the pressure sensor 10 will send a stable pressure signal to the external display device, the operator can intuitively know the tension of the steel strip when it is reeled, if the steel strip maintains appropriate tension, the pressure roller 8 will remain in a relatively stable position, the compression amount of the reset spring 13 will also be maintained within a reasonable range, at this time the pressure sensor 10 will send a stable pressure signal to the external display device, the operator can intuitively know the tension of the steel strip when it is reeled, Relaxation occurs, that is, the force applied by the steel belt to the pressure roller 8 decreases, and the return spring 13 will begin to release the stored energy due to the previous compression, pushing the pressure roller 8 to move downward. This movement will cause the position of the slide bar 12 in the slide cylinder 11 to change, reducing the compression of the return spring 13. The pressure sensor 10 will immediately detect this change and send the reduced pressure value to the external display device. The operator can quickly determine whether the steel belt is relaxed by observing the pressure value change on the display device and take corresponding measures to restore the tension of the steel belt to ensure the stability of the heat treatment process and the quality of the product. At the same time, the infrared generator 6 will be started during winding. The receiver 7 receives the infrared rays emitted by the infrared generator 6. When the steel strip deviates during winding, the deviated steel strip blocks the infrared receiver 7, causing the infrared receiver 7 to be unable to receive the complete infrared signal. The infrared receiver 7 sends a signal to the PLC controller 2. After processing, the PLC controller 2 activates the sound and light alarm 3. The sound and light alarm 3 gives a sound and light alarm, thereby reminding the operator to come and deal with the deviation problem of the steel strip to avoid affecting the winding effect. When the motor 15 is started for winding, the torque sensor 16 monitors the first connecting shaft 17 in real time to accurately measure and capture the torque changes generated during the winding process. The torque sensor 16 will send the torque data to the PLC controller 2. The PLC controller 2 will compare and judge the received torque data with the preset standard value. If the torque value is too high, it indicates that the steel belt may have encountered resistance or excessive tension when winding. At this time, the PLC controller 2 will adjust the speed of the motor 15 and reduce the torque output to reduce the tension of the steel belt and avoid excessive stretching or damage. On the contrary, if the torque value is too low, it indicates that the steel belt may be too loose when winding. At this time, the PLC controller 2 will appropriately increase the speed of the motor 15 and increase the torque output to enhance the tension of the steel belt, ensure that the winding is tight and there is no slack, and achieve a uniform winding effect.
