Description

Technical Field

[0001] This utility model relates to the field of tenter frame technology, and in particular to an integrated mechanism for adaptive positioning and correction of fabric in tenter frames. Background Technology

[0002] Tensor stretchers are key equipment in the textile printing and dyeing industry. They are mainly used to stretch and adjust the width of textile fabrics. By controlling the tension of the fabric, they can achieve the predetermined width and dimensional stability. During the printing and dyeing process, tenter stretchers can ensure that the fabric remains flat and wrinkle-free after dyeing, printing and other processes, thereby improving product quality and production efficiency.

[0003] Traditional tenter frames often lack a correction mechanism, which makes the conveyor belt prone to deviation during long-distance fabric transport due to the combined effects of various factors. Once this deviation occurs, it will directly interfere with the normal trajectory of the fabric, thereby affecting subsequent processing stages.

[0004] Therefore, those skilled in the art have provided an integrated adaptive positioning and correction mechanism for fabric in a tenter frame to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated adaptive positioning and correction mechanism for tenter fabric. Compared to traditional tenter fabric adaptive positioning and correction mechanisms, this new mechanism uses a limiting roller to limit the fabric's movement and a positioning roller to position the fabric at its initial location. After monitoring the fabric's movement through sensors, a moving mechanism rotates and moves the correction rollers in both the left and right directions to ensure the fabric is corrected, allowing it to move along a predetermined path and guaranteeing fabric processing quality. An adjustment mechanism is also included, using bolts and nuts to adjust the positions of the limiting rollers and sensors, ensuring the mechanism is suitable for correcting fabrics of different thicknesses and widths, effectively expanding its applicability to various environments.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An integrated adaptive positioning and correction mechanism for fabric in a tenter frame includes a base, multiple sensors, and multiple limiting rollers. Support plates are fixedly connected to both sides of the upper surface of the base. A moving mechanism is provided at the front end of the middle part of the upper surface of the base. The moving mechanism includes a third base plate. A motor is fixedly connected to the center of the upper surface of the third base plate. A gear is fixedly connected to the output end of the motor. Brackets are fixedly connected to the front and rear parts of the front end of the middle part of the upper surface of the base. A cylinder is fixedly connected to the center of the front end of the middle part of the upper surface of the base.

[0008] The front and rear ends of the inner wall of the support plate are provided with adjustment mechanisms. The adjustment mechanism includes a first bearing and a first mounting bracket fixedly connected to the front and rear ends of the inner wall of the support plate. The inner top and inner bottom surfaces of the first mounting bracket are provided with positioning grooves. The upper and lower surfaces of the first bearing are fixedly connected with positioning blocks. The outer wall of the first bearing away from the middle of the base is fixedly connected with a first bolt. The first bolt is threadedly connected with multiple first nuts. The front and rear ends of the upper surface of the support plate are fixedly connected with fixing plates. The body of the fixing plate is provided with positioning holes. The inner wall of the fixing plate is provided with a second mounting bracket. The outer wall of the second mounting bracket is provided with a second bolt. The second bolt is threadedly connected with a second nut. The outer wall of the sensor away from the middle of the base is fixedly connected with a third bolt. The third bolt is threadedly connected with multiple third nuts.

[0009] Through the above technical solution, the tenter frame's integrated adaptive positioning and correction mechanism for fabric is equipped with a moving mechanism to effectively correct the deviation of the fabric during movement. The mechanism also moves the sensor and the limit roller through the adjustment mechanism, thereby adapting it to fabrics of different thicknesses and sizes.

[0010] Furthermore, a first base plate is provided at the rear end of the middle of the upper surface of the base. A second bearing is fixedly connected to both ends of the upper surface of the first base plate. A positioning roller is rotatably connected to the inner wall of the second bearing. A second base plate is fixedly connected to the upper surface of the moving mechanism. A third bearing is fixedly connected to both ends of the upper surface of the second base plate. A correction roller is rotatably connected to the inner wall of the third bearing. The positioning roller and the correction roller are both provided with concave and convex textures.

[0011] The above technical solution uses bearings to fix the positioning roller and the correction roller, ensuring that the two rollers can rotate freely, which facilitates the movement of the fabric. At the same time, the roller body is provided with concave and convex textures, which increases the friction with the fabric to a certain extent, making it easier to correct the fabric's deviation.

[0012] Furthermore, all the limiting rollers are rotatably connected to the first bearing, and all the sensors are disposed on the upper surface of the second mounting bracket;

[0013] With the above technical solution, the limiting roller is fixed by bearings, which facilitates rotation, and the sensor is set on the mounting frame to facilitate the movement of the sensor.

[0014] Furthermore, a controller is fixedly connected to one outer wall of the base;

[0015] The above technical solution uses a controller to control the moving mechanism to perform operations, thereby more accurately correcting the fabric's deviation.

[0016] Furthermore, a slide rail is fixedly connected to the upper surface of the bracket, and a slide groove is provided at both the front and rear ends of the lower surface of the third base plate. The slide rail and the slide groove correspond one-to-one and slide rail and slide groove slide in fit. The output end of the cylinder is fixedly connected to one side of the outer wall of the third base plate.

[0017] Through the above technical solution, the cylinder drives the third base plate to move, thereby driving the correction roller to move for correction. During correction, the slide groove and slide rail can play a certain role in limiting and guiding, while the bracket supports the third base plate.

[0018] Furthermore, arc-shaped limiting grooves are provided on both sides of the upper surface of the third base plate, and rollers are fixedly connected to both sides of the lower surface of the second base plate. The rollers and the arc-shaped limiting grooves correspond one-to-one, and the rollers move within the arc-shaped limiting grooves.

[0019] Through the above technical solution, the roller supports the second base plate and the correction roller. At the same time, when the correction roller rotates, the roller moves in the arc-shaped limiting groove, which plays a certain guiding and limiting role.

[0020] Furthermore, the upper surface of the gear is fixedly connected to the middle part of the lower surface of the second base plate;

[0021] With the above technical solution, the gear and the second base plate are fixedly connected, which makes it easy for the motor to drive the gear to rotate, thereby driving the second base plate to rotate, and thus driving the straightening roller to rotate.

[0022] Furthermore, the positioning grooves and positioning blocks correspond one-to-one, and the first mounting bracket and the first bearing are slidably connected.

[0023] Through the above technical solution, when adjusting the first bearing, the positioning groove and positioning block work together to guide the movement of the first bearing and prevent the first bearing from shifting.

[0024] This utility model has the following beneficial effects:

[0025] 1. The present invention proposes an integrated adaptive positioning and correction mechanism for tenter fabric. Compared with most existing integrated adaptive positioning and correction mechanisms for tenter fabric, this integrated adaptive positioning and correction mechanism for tenter fabric is equipped with a limiting roller to limit the fabric and a positioning roller to position the fabric at its initial position. After monitoring the movement of the fabric through a sensor, the correction roller is rotated and moved left and right through a moving mechanism to ensure that the fabric is corrected, so that the fabric moves along a predetermined route and ensures the quality of fabric processing.

[0026] 2. The tenter frame fabric adaptive positioning and correction integrated mechanism proposed in this utility model, compared with most existing tenter frame fabric adaptive positioning and correction integrated mechanisms, is equipped with an adjustment mechanism. Through the cooperation of bolts and nuts, the position of the limit roller and sensor is adjusted, thereby ensuring that the mechanism is applicable to fabric correction scenarios of different thicknesses and widths, effectively expanding its applicable range of use environments.

The limiting rollers 5 are all rotatably connected to the first bearing 1101. The sensors 3 are all set on the upper surface of the second mounting frame 1109. The limiting rollers 5 are fixed by the bearings, which facilitates rotation. The sensors 3 are set on the mounting frame to facilitate the movement of the sensors 3.

[0043] Reference Figure 4 and Figure 5A controller 4 is fixedly connected to one outer wall of the base 1.

One side of the outer wall of the second base plate 9 is fixedly connected. The cylinder 1007 drives the third base plate 1005 to move, thereby driving the correction roller 8 to move for correction. During correction, the slide groove 1009 and the slide rail 1008 can play a certain role in limiting and guiding. At the same time, the bracket 1006 supports the third base plate 1005.

Rollers 1003 are fixedly connected to both sides of the lower surface of the second base plate 9. Rollers 1003 and arc-shaped limiting grooves 1004 correspond one-to-one. Rollers 1003 move within arc-shaped limiting grooves 1004, supporting the second base plate 9 and the correction roller 8. Simultaneously, as the correction roller 8 rotates, rollers 1003 move within arc-shaped limiting grooves 1004, providing guidance and limiting. The upper surface of gear 1002 is fixedly connected to the middle of the lower surface of the second base plate 9. The fixed connection between gear 1002 and the second base plate 9 facilitates rotation of the second base plate 9 when the motor 1001 drives gear 1002, thereby rotating the correction roller 8. Positioning grooves 1105 and positioning blocks 1106 correspond one-to-one. The first mounting bracket 1102 and the first bearing 1101 are slidably connected. When adjusting the first bearing 1101, the cooperation of positioning grooves 1105 and positioning blocks 1106 guides the movement of the first bearing 1101, preventing it from shifting.

[0044] Working principle: The fabric is inserted through the rear limiting roller 5, passes through the positioning roller 6 and the correction roller 8, and then exits through the front limiting roller 5. Based on the fabric thickness, the first bolt 1103 and the second bolt 1110 are adjusted to ensure the fabric is properly tensioned on the limiting roller 5. Based on the fabric width, the third bolt 1112 is adjusted to ensure the front and rear sensors 3 are in the correct positions. Then, the tenter frame is started to move the fabric. During the fabric movement, if a shift in fabric position between the two limiting rollers 5 is detected, the front sensor... When sensor 3 generates an alarm, controller 4 controls motor 1001 to start, which drives gear 1002 to rotate, which in turn drives second base plate 9 to rotate, thereby driving correction roller 8 to rotate and reset the fabric. When second base plate 9 rotates, roller 1003 moves on arc-shaped limit groove 1004 to support second base plate 9. When the entire fabric is deviated and both front and rear sensors 3 generate alarms, cylinder 1007 is activated to drive third base plate 1005 to slide on bracket 1006, thereby correcting the fabric deviation.
