Description

Technical Field

[0001] The present invention relates to the technical field of fabric transmission, and specifically relates to a speed regulation and positioning control device for a fabric transmission mechanism. Background Technique

[0002] In industries such as textile printing and dyeing, and garment manufacturing, the fabric transmission mechanism is the core component for realizing continuous fabric processing, and its performance directly affects product quality and production efficiency.

[0003] Based on the above, the following problems are found: In the design of existing fabric transmission mechanisms, they often only focus on the basic transmission function of the fabric and do not have effective positioning control and speed regulation components. In actual production, the fabric is extremely prone to lateral deviation due to factors such as uneven force and deviation in the parallelism of the rollers when driven by conveyor rollers and conveyor belts, which will have a serious impact on the subsequent winding link, making the edges of the wound fabric uneven and unable to meet the production and use requirements. Moreover, the transmission mechanism cannot flexibly adjust the winding speed according to the characteristics of the fabric such as material and thickness. The mismatch between the winding speed and the conveying speed will cause the fabric to pile up or wrinkle, thereby affecting the regularity of winding.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a speed regulation and positioning control device for a fabric transmission mechanism is provided, with the expectation of achieving a more practical value. Summary of the Invention

[0005] The purpose of the present invention is to provide a speed regulation and positioning control device for a fabric transmission mechanism to solve the problem that in the design of existing fabric transmission mechanisms, they often only focus on the basic transmission function of the fabric and do not have effective positioning control and speed regulation components as mentioned in the above background technique.

[0006] In view of the above problems, the technical solution proposed by the present invention is: A speed regulation and positioning control device for a fabric transmission mechanism, including a winding mechanism, a transmission mechanism, and a positioning mechanism. The winding mechanism includes a box body, inside which a pair of rollers are rotatably connected. A base is slidably installed at the bottom end of the box body, and a guide roller is fixedly installed on one side of the box body. The transmission mechanism includes a transmission box, one side of which is connected to one end of the box body. A servo motor is fixedly installed on one side of the transmission box, and a frequency converter is fixedly installed on one side of the servo motor. The positioning mechanism includes a fixed rod, one end of which is slidably inserted with a sliding rod. One end of the sliding rod is fixedly installed with a connecting block, and a first adjusting screw is threadedly connected to the center of the connecting block. The bottom end of the first adjusting screw is rotatably connected to a deviation correction sensor.

[0007] Furthermore, one end of each of the rollers passes through the box body and extends to the interior of the transmission box, and each of the rollers is sleeved with a synchronous wheel, and a synchronous belt is wound between the pair of synchronous wheels.

[0008] The beneficial effect of adopting the above further scheme is that the synchronous wheel and synchronous belt transmission at one end of the roller can ensure the synchronous rotation of a pair of rollers, so that the cloth is evenly stressed during the winding process, avoiding deviation, wrinkles and the like, and ensuring the flatness and stability of the cloth winding.

[0009] Furthermore, the output end of the servo motor is transmission-connected to one of the synchronous wheels, and the servo motor is electrically connected to the frequency converter via a wire.

[0014] The beneficial effect of adopting the above-mentioned further scheme is that the limit rod of the correction sensor slides with the sleeve to guide and limit the correction sensor to prevent it from shifting during the detection process. The height of the correction sensor can be adjusted by rotating the first adjusting screw, and its horizontal position can be adjusted by rotating the second adjusting screw, thereby accurately adjusting the detection position of the correction sensor and improving the accuracy of fabric positioning.

[0015] Furthermore, it also includes a limiting mechanism, which includes a pair of guide rods and a pair of abutment plates, and sliders are fixedly installed on both sides of the bottom ends of the abutment plates. Each pair of sliders is slidably connected to a pair of the guide rods, and the bottom ends of the abutment plates are provided with arc grooves adapted to the outer surfaces of the pair of rollers.

[0017] Furthermore, locking bolts are threadedly connected to the upper ends of the sliders, and the bottom ends of the locking bolts abut against the upper ends of the guide rods. One side of one of the sliders is connected to one end of the fixed rod.

[0018] The beneficial effect of adopting the above further solution is that the locking bolts on the sliders can fix the abutting plate on the guide rod, prevent the abutting plate from displacing during fabric transmission, ensure the stable and reliable limiting effect, and one of the sliders is connected to the fixed rod, enabling the limiting mechanism and the positioning mechanism to cooperate with each other to jointly achieve precise control of the fabric position.

[0019] Furthermore, a second telescopic rod is fixedly installed inside the base, a fixed block is fixedly installed on the bottom side of the box body, and one end of the second telescopic rod is connected to the fixed block.

[0020] The beneficial effect of adopting the above further solution is that the second telescopic rod inside the base is connected to the fixed block, and the left and right positions of the box body can be adjusted by telescoping. Combined with the deviation correction sensor, when the fabric deviates, the position of the box body can be adjusted in a timely manner, improving the regularity of fabric winding.

[0021] Furthermore, a controller is fixedly installed on one side of the frequency converter.

[0022] The beneficial effect of adopting the above further solution is that the controller is electrically connected to the frequency converter, the servo motor, the first telescopic rod, the second telescopic rod, and the deviation correction sensor through wires, which facilitates the user to control the operation of the device using the controller and receive and process the monitoring information sent by the deviation correction sensor.

The operator can adjust the speed of the servo motor 204 through the frequency converter 202, and then flexibly adjust the transmission speed of the cloth to meet the requirements of different production processes for the cloth transmission speed. The first telescopic rod 207 and the tensioning wheel 208 in the transmission box 201 can adjust the position of the tensioning wheel 208 through the first telescopic rod 207 according to the tightness of the synchronous belt 206, so that the synchronous The belt 206 always maintains appropriate tension to ensure the stability and reliability of the transmission of the synchronous belt 206, and avoids transmission failure caused by the relaxation of the synchronous belt 206. The limit rod 406 of the correction sensor 404 slides with the sliding sleeve 408 to guide and limit the correction sensor 404 to prevent it from deviating during the detection process.

[0029] Please refer to Figure 1 - Figure 6 Inside the base 104, a second telescopic rod 105 is fixedly installed. A fixed block 106 is fixedly installed on the bottom side of the box body 101. One end of the second telescopic rod 105 is connected to the fixed block 106. On one side of the frequency converter 202, a controller 203 is fixedly installed. The second telescopic rod 105 inside the base 104 is connected to the fixed block 106, and the left and right positions of the box body 101 can be adjusted by telescoping.

The controller 203 controls the second telescopic rod 105 inside the base 104 to expand and contract to adjust the left and right positions of the box body 101 for deviation correction. At the same time, the operator can adjust the height and horizontal position of the deviation correction sensor 404 by rotating the first adjustment screw 405 and the second adjustment screw 403 to ensure detection accuracy.
