Description

Technical Field

[0001] This utility model is a guide component for knitted fabric processing, belonging to the field of guide components. Background Technology

[0002] In the field of knitted fabric processing, guide components are key equipment to ensure smooth fabric transport and processing. The basic structure of existing knitted fabric processing guide equipment typically consists of a frame, drive roller assembly, tensioning device, and simple guide structure. The frame, as the main body of the equipment, is used to support and fix other components. The drive roller assembly generally consists of two drive rollers, upper and lower, driven by a motor to achieve traction and transport of the knitted fabric. The tensioning device mostly adopts a fixed structure or a simple spring adjustment method, using mechanical force to tension the fabric. The guide structure mainly relies on fixed guide rollers to provide a basic guiding path for the fabric. In the field of knitted fabric processing, the drive roller assembly of guide equipment mostly adopts a fixed spacing or manual screw adjustment method. The fixed spacing drive roller assembly is fastened to the equipment frame by welding or bolting, which is suitable for fabrics of conventional thickness. The manual screw adjustment relies on rotating the screw to drive the drive roller to move along the linear guide rail to achieve fine adjustment of the spacing. Traditional manual screw adjustment has significant drawbacks. Changes in the drive roller spacing disrupt the tension and meshing accuracy of transmission components such as gears and belts. Gear drives experience abnormal meshing clearances due to changes in center distance, leading to slippage and jamming. Belt drives suffer from slippage or excessive wear due to tension imbalance. Maintaining normal drive roller rotation requires additional adjustments to the transmission component positions or replacement with appropriately sized parts, resulting in complex operations, time-consuming setup, and high operator skill requirements. This makes it difficult to adapt to the diverse fabric processing needs. Therefore, designing a guide component for knitted fabric processing is essential. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a guiding component for knitted fabric processing to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a guiding component for knitted fabric processing includes a guiding platform, a gantry frame installed at one end of the top of the guiding platform, a driving component provided on one side inside the gantry frame, an upper driving roller rotatably connected to the top of the other side inside the gantry frame via a hanging mounting plate, a lower driving roller installed in the gantry frame below the upper driving roller via a lifting frame, an adjusting screw passing through the guiding platform below the lifting frame, the top of the adjusting screw being rotatably connected to the bottom of the lifting frame, a correction component installed at the center of the top of the guiding platform, and a tensioning component provided at the end of the top of the guiding platform away from the gantry frame.

[0005] Furthermore, a lifting groove is provided on the side of the gantry away from the drive assembly, and a slider with a matching shape is provided in the lifting groove. The slider passes through the lifting groove and is fixedly connected to the side wall of the lifting frame. A connecting sleeve is fixed on the other side of the lifting frame. The lifting frame has a "U"-shaped design and is rotatably connected to the lower drive roller.

[0006] Furthermore, the correction assembly includes a mounting base, a servo motor, a turntable, a mounting frame, and correction rollers. The top of the mounting base has a rotating groove, and the turntable is rotatably connected inside the rotating groove. The servo motor is located at the center of the mounting base, and the output end of the servo motor is connected to the turntable. The top of the turntable is fixedly connected to the mounting frame, and correction rollers are rotatably connected to both sides of the top of the mounting frame.

[0007] Furthermore, the tensioning assembly includes side plates, a lead screw, a lead screw nut, an adjusting handle, an adjusting roller, an upper tensioning roller, and a discharge roller assembly. Side plates are symmetrically arranged on both sides of the top of the guide platform, and the side plates have movable grooves inside. A lead screw is installed in the movable groove, and a lead screw nut is fitted on the lead screw. An adjusting roller is rotatably connected between the two lead screw nuts, and an upper tensioning roller parallel to the adjusting roller is rotatably connected between the side plates at both ends of the adjusting roller. A discharge roller assembly is installed between the two side plates near the correction assembly, and the discharge roller assembly includes two discharge rollers arranged vertically and horizontally. An adjusting handle is rotatably connected to the top of the side plate, and the bottom of the adjusting handle is connected to the lead screw.

[0008] Furthermore, a connecting rod is provided between the two side plates near one end of the correction assembly, and an offset detection assembly is installed on the connecting rod. The offset detection assembly includes an infrared sensor, an adjustment knob, a movable sleeve, and a fastening knob. The inner diameter of the movable sleeve matches the outer diameter of the connecting rod, and a fastening knob is installed at one end of the movable sleeve. An infrared sensor is hinged to the top of the movable sleeve, and an adjustment knob is provided at the hinge between the infrared sensor and the movable sleeve.

[0009] Furthermore, the drive assembly includes a drive motor, a drive rod, a first bevel gear, a second bevel gear, and a third bevel gear. The drive rod is vertically arranged and rotatably connected to the gantry frame. The drive motor is installed in the guide platform below the drive motor, and the output end of the drive motor is connected to the drive rod.

[0012] 1. The device is equipped with a drive assembly and an adjustable lifting frame. By rotating the adjusting screw, the lifting frame can be moved up and down to precisely adjust the distance between the lower and upper drive rollers. During the adjustment process, as the lower drive roller moves with the lifting frame, the third bevel gear can move axially along the drive rod, always maintaining good meshing with the second bevel gear on the lower drive roller. No additional adjustments to the transmission assembly are required to ensure stable relative rotation of the upper and lower drive rollers to transport the fabric. This design not only makes the adjustment operation simple and quick, greatly shortening the debugging time, but also reduces the technical requirements for operators and can efficiently adapt to the processing of knitted fabrics of different thicknesses.

[0013] 2. The tensioning assembly, driven by a lead screw and nut, allows for easy adjustment of the position of the adjusting roller, achieving precise control over the fabric tension. Appropriate tension helps ensure fabric stability during transport, preventing slack or excessive tightness from negatively impacting processing. This ensures the fabric smoothly and orderly enters subsequent processing steps. The correction assembly, based on precise control of a servo motor and turntable, can quickly respond to fabric deviations. By rotating the correction roller, it promptly corrects the fabric's trajectory. Combined with real-time monitoring by the deviation detection assembly, it effectively prevents fabric deviation, wrinkles, and other problems during processing, ensuring the quality of knitted fabrics and improving the finished product qualification rate.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 8This utility model provides a technical solution: a guide assembly for knitted fabric processing, including a guide platform 1, a gantry frame 2 installed at one end of the top of the guide platform 1, a drive assembly 8 provided on one side inside the gantry frame 2, an upper drive roller 3 rotatably connected to the top of the other side inside the gantry frame 2 via a hanging mounting plate 202, a lower drive roller 4 installed in the gantry frame 2 below the upper drive roller 3 via a lifting frame 5, an adjusting screw 9 passing through the guide platform 1 below the lifting frame 5, the top of the adjusting screw 9 rotatably connected to the bottom of the lifting frame 5, a correction assembly 6 installed at the center of the top of the guide platform 1, and a tensioning assembly 7 provided at the end of the top of the guide platform 1 away from the gantry frame 2, the lower drive roller 4 installed in the gantry frame 2 via the lifting frame 5, the operator only needs to rotate the adjusting screw 9 to drive the lifting frame 5 to move up and down in the gantry frame 2, accurately adjust the distance between the lower drive roller 4 and the upper drive roller 3, thereby adapting to knitted fabrics of different thicknesses and greatly improving the versatility of the equipment;

[0026] For example, a lifting groove 201 is provided on the side of the gantry frame 2 away from the drive assembly 8, and a slider 502 with a matching shape is provided in the lifting groove 201. The slider 502 passes through the lifting groove 201 and is fixedly connected to the side wall of the lifting frame 5. A connecting sleeve 501 is fixed on the other side of the lifting frame 5. The lifting frame 5 has a "U"-shaped design and is rotatably connected to the lower drive roller 4. The slider 502 passes through the lifting groove 201 and is fixedly connected to the side wall of the lifting frame 5. This allows the lifting frame 5 to maintain a stable linear motion trajectory when moving along the lifting groove 201, effectively avoiding deviation and shaking, and providing a reliable guarantee for the smooth lifting of the lower drive roller 4.

[0027] For example, the correction assembly 6 includes a mounting base 28, a servo motor 29, a turntable 30, a mounting frame 31, and correction rollers 32. The top of the mounting base 28 has a rotating groove 2801, and the turntable 30 is rotatably connected within the rotating groove 2801. The servo motor 29 is located at the center of the mounting base 28, and its output end is connected to the turntable 30. The top of the turntable 30 is fixedly connected to the mounting frame 31, and correction rollers 32 are rotatably connected to both sides of the top of the mounting frame 31. When an offset is detected... When the infrared sensor 24 in component 18 detects a shift in the knitted fabric and blocks the sensing signal, the servo motor 29 responds quickly and starts. The servo motor 29 drives the turntable 30 to rotate in the rotating groove 2801, which in turn causes the mounting frame 31 to rotate synchronously with the turntable 30. The correction roller 32 rotates at a certain angle under the drive of the mounting frame 31, thereby applying a lateral force to the fabric. This lateral force can accurately correct the shifted fabric to the correct running track, effectively avoiding problems such as fabric deviation and wrinkles.

[0028] Please see Figure 3The tensioning assembly 7 includes side plates 10, lead screws 11, lead nuts 12, adjusting handles 13, adjusting rollers 14, upper tensioning rollers 15, and discharge roller groups 16. Side plates 10 are symmetrically arranged on both sides of the top of the guide platform 1, and each side plate 10 has a movable groove 1001 inside. A lead screw 11 is installed in the movable groove 1001, and a lead nut 12 is fitted onto the lead screw 11. An adjusting roller 14 is rotatably connected between the two lead nuts 12. Upper tensioning rollers 15, parallel to the adjusting roller 14, are rotatably connected between the side plates 10 at both ends of the adjusting roller 14. A discharge roller group 16 is installed between the two side plates 10 near the correction assembly 6, and the discharge roller group 16 includes two upper tensioning rollers... The discharge rollers are arranged in parallel. The top of the side plate 10 is rotatably connected to the adjustment handle 13, and the bottom of the adjustment handle 13 is connected to the lead screw 11. When the knitted fabric passes through, it passes through the upper tension roller 15 on the left, the adjustment roller 14 and the upper tension roller 15 on the right in sequence, and is finally discharged by the discharge roller group 16. The operator can adjust the height of the adjustment roller 14 by rotating the adjustment handle 13 according to the material, thickness and other characteristics of the fabric. If the fabric needs tighter tension, the adjustment handle 13 can be rotated to move the adjustment roller 14 down, increasing the pressure between the adjustment roller 14 and the upper tension roller 15, thereby tightening the fabric. Conversely, if the fabric tension is too high, the adjustment roller 14 can be moved up to loosen the fabric.

[0029] Please see Figure 3 and Figure 8 A connecting rod 17 is located between the two side plates 10 near one end of the correction assembly 6, and an offset detection assembly 18 is mounted on the connecting rod 17. The offset detection assembly 18 includes an infrared sensor 24, an adjustment knob 25, a movable sleeve 26, and a fastening knob 27. The inner diameter of the movable sleeve 26 matches the outer diameter of the connecting rod 17, and a fastening knob 27 is mounted on one end of the movable sleeve 26. The infrared sensor 24 is hinged to the top of the movable sleeve 26, and an adjustment knob 25 is located at the hinge point between the infrared sensor 24 and the movable sleeve 26. The infrared sensor 24 can monitor the offset in real time. The fabric position detection system can quickly respond to any deviations in the fabric that obstruct the sensor signal. Compared to traditional manual observation or simple mechanical detection, this greatly improves the timeliness and accuracy of detection, providing a reliable basis for timely correction. The movable sleeve 26 works in conjunction with the connecting rod 17, and the installation position can be flexibly adjusted via the fastening knob 27 to adapt to fabrics of different widths and running paths. The adjustment knob 25 at the hinge of the infrared sensor 24 and the movable sleeve 26 can change the detection angle as needed, accurately covering the fabric running area and enhancing the adaptability of the component to diverse processing requirements.

[0030] Please see Figure 4The drive assembly 8 includes a drive motor 19, a drive rod 20, a first bevel gear 21, a second bevel gear 22, and a third bevel gear 23. The drive rod 20 is vertically arranged and rotatably connected to the gantry frame 2. The drive motor 19 is installed in the guide platform 1 below it, and the output end of the drive motor 19 is connected to the drive rod 20. The first bevel gear 21 is fixed to the top of the drive rod 20, and the third bevel gear 23 is movably connected to the drive rod 20 below the first bevel gear 21. The first bevel gear 21 and the third bevel gear 23 are arranged symmetrically vertically. Furthermore, the upper drive roller 3 and the lower drive roller 4 are each provided with a second bevel gear 22 that meshes with the first bevel gear 21 and the third bevel gear 23. When the lower drive roller 4 moves with the lifting frame 5 to adjust the distance between it and the upper drive roller 3, the third bevel gear 23 can move axially along the drive rod 20 and still maintain a good meshing state with the second bevel gear 22. When adjusting the distance between the drive rollers to adapt to knitted fabrics of different thicknesses, there is no need to make complex adjustments to the transmission components to ensure normal power transmission, which greatly improves the versatility and ease of use of the equipment.

[0031] Please see Figure 4 and Figure 6 Three protruding ridges 2001 are evenly distributed on the outer wall of the lower half of the drive rod 20. The bottom of the third bevel gear 23 is integrally connected to a sleeve 2301 whose inner diameter matches the outer diameter of the drive rod 20. A limiting groove 2302 adapted to the ridges 2001 is provided on the inner wall of the sleeve 2301. The sleeve 2301 is rotatably connected to the connecting sleeve 501. When it is necessary to adjust the distance between the upper drive roller 3 and the lower drive roller 4, the lower drive roller 4 will move up and down with the lifting frame 5. The sleeve 2301 is rotatably connected to the connecting sleeve 501, and the sleeve 2301 engages with the protrusion 2001 on the drive rod 20 through the limiting groove 2302. Therefore, the third bevel gear 23 can move axially on the drive rod 20. During the movement, the protrusion 2001 always slides in the limiting groove 2302, ensuring that even if the distance between the drive rollers changes, the third bevel gear 23 can still rotate with the drive rod 20 and continuously transmit power to the lower drive roller 4, ensuring the continuity of power transmission.

[0032] Detailed Implementation: In use, the drive motor 19 starts, driving the drive rod 20 to rotate. The first bevel gear 21 and the third bevel gear 23 on the drive rod 20 rotate accordingly, meshing with the second bevel gear 22 on the upper drive roller 3 and the lower drive roller 4, causing the upper drive roller 3 and the lower drive roller 4 to rotate relative to each other, pulling the knitted fabric forward. When it is necessary to accommodate knitted fabrics of different thicknesses, the adjusting screw 9 is rotated, causing the lifting frame 5 to move up and down along the lifting groove 201, thereby adjusting the distance between the lower drive roller 4 and the upper drive roller 3. During this process, the sleeve 2301 of the third bevel gear 23 engages with the protrusion 2001 of the drive rod 20 through the inner wall limiting groove 2302, allowing it to move axially along the drive rod 20, ensuring continuous power. Continuing the transmission, the infrared sensor 24 of the offset detection component 18 monitors the fabric position in real time. When the fabric deviates and obstructs the sensing signal, the signal is fed back to the control system, triggering the servo motor 29 of the correction component 6 to start. The servo motor 29 drives the turntable 30 to rotate, causing the mounting frame 31 and the correction roller 32 to rotate at a certain angle, applying lateral force to the fabric and correcting it to the correct running track. The adjusting handle 13 of the tensioning component 7 is rotated, driving the lead screw 11 to rotate, causing the nut 12 to move on the lead screw 11, which in turn drives the adjusting roller 14 to move up and down, thereby adjusting the tension of the fabric and ensuring that the fabric maintains appropriate tension during the conveying process.
