Description

Technical Field

[0001] This utility model relates to the technical field of fabric grading equipment, specifically a fabric grading machine with automatic deviation correction for polyester-cotton fabric. Background Technology

[0002] Fabric arranging machines are a type of textile post-processing equipment, mainly used in textile mills, dyeing and printing plants for arranging and inspecting fabrics. Polyester-cotton fabric, a common textile, is widely used due to its combination of the high strength of polyester fibers and the strong moisture absorption of cotton fibers.

[0003] In the process of stacking polyester-cotton fabric, fabric deviation is a common and troublesome problem. Traditional stacking machines often lack an effective correction mechanism when processing polyester-cotton fabric, which can easily lead to skewed rolls and affect product quality. Although some stacking machines have a manual correction step, relying on manual straightening of the fabric edges is not only inefficient, but also makes it difficult to guarantee the accuracy of correction, which cannot meet the needs of modern large-scale, high-precision production.

[0004] In addition, during the conveying process, polyester-cotton fabric will rub against various parts of the equipment, which can easily generate static electricity. Under the action of static electricity, local fabrics will stick together and form wrinkles. However, existing fabric lining machines lack effective flattening aids, which undoubtedly greatly reduces the flatness of the fabric lining. Utility Model Content

[0005] In view of the above-mentioned background technology, the existing technology of traditional fabric stacking machine lacks an effective correction mechanism when stacking polyester-cotton fabric. It relies on manual correction, which has the problems of low efficiency and poor accuracy, and is difficult to meet the needs of large-scale high-precision production.

[0006] The automatic correction fabric stacking machine for polyester-cotton fabric disclosed in this utility model includes a fixed frame. Two feeding rollers are provided at one end of the fixed frame. A detection component is provided on one side of the feeding rollers. A support frame one and a support frame two are provided on the other side of the feeding rollers. A correction component is provided on the support frame one, and an air jet auxiliary component is provided on the support frame two.

[0007] Furthermore, the correction component includes a support block, which is rotatably mounted on the support frame. A support rod is mounted on the support block, sleeves are provided on both sides of the support block, and the sleeves are rotatably mounted on the support rod. Rollers are provided at both ends of the support rod.

[0008] Furthermore, the correction assembly also includes a ball screw, which is rotatably mounted on the support frame one. One end of the ball screw passes through the fixed frame, and a drive source one is provided at one end of the ball screw. The drive source one is mounted on the fixed frame, and sliders are symmetrically arranged at both ends of the support frame one. The upper end of the slider is set as an inclined surface, and the inclined surface contacts the roller.

[0009] Furthermore, the jet auxiliary component includes a fixing block, and multiple fixing blocks are provided. Both ends of each fixing block are rotatably mounted on the support frame two via a rotating shaft. The fixing block is provided with a nozzle, and the nozzle is connected to an external air source.

[0010] Furthermore, gears are provided on the rotating shafts on the same side, and a rack meshes with one side of the gears. The rack is slidably disposed with the second support frame. A second drive source is provided on the second support frame away from the gears, and the second drive source is connected to one of the rotating shafts.

[0011] Furthermore, the rack and the gear are provided with a housing on their outer sides, and the housing is fixedly connected to the support frame II by fixing bolts.

[0012] Furthermore, the detection component includes an infrared transmitter and an infrared receiver, which are mounted on a mounting bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model can keenly detect fabric deviation by using an infrared transmitter and receiver in the detection component. The various components in the correction component work together, with the support block, ball screw, slider, etc. working in coordination. Driven by the drive source at one end of the ball screw, the slider is adjusted by contact between the inclined surface and the roller, achieving automatic and precise correction. This prevents the polyester-cotton fabric from rolling out crookedly, greatly improving production efficiency, ensuring stable and reliable product quality, and well adapting to modern production requirements.

[0015] 2. This utility model is equipped with an air jet auxiliary component. The nozzle on the fixed block can be connected to an external air source. The drive source drives the rotating shaft to rotate. With the cooperation of gears and racks, the fixed block can be rotated, and the nozzle sprays gas to act on the polyester-cotton fabric. This helps to eliminate wrinkles caused by static electricity and other reasons, and plays a smoothing role on the polyester-cotton fabric, effectively improving the flatness of the fabric and ensuring the fabric laying effect.

[0022] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please see Figure 1 The present invention relates to an automatic polyester-cotton fabric straightening machine, which includes a fixed frame 1. A controller 20 is provided on one side of the fixed frame 1. The controller 20 adopts a PLC controller to coordinate the operation of the detection component, the straightening component and the air jet auxiliary component. Two feed rollers 2 are provided at one end of the fixed frame 1. A detection component is provided on one side of the feed rollers 2. The detection component includes an infrared transmitter 3 and an infrared receiver 4.

[0024] See Figure 1 , Figure 2 , Figure 3 As shown, the infrared transmitter 3 and the infrared receiver 4 are both mounted on the fixed frame 1 by fixing bolts. The infrared receiver 4 is connected to the controller 20 by a signal line, which can convert the occlusion signal into an electrical signal and transmit it to the controller 20 to provide a trigger command for the subsequent correction action. On the other side of the feed roller 2, there is a support frame 5 and a support frame 13. The correction component is provided on the support frame 5, which includes a support block 9.

[0025] In this embodiment, the support block 9 is rotatably mounted on the support frame 5. The support block 9 is rotatably mounted in the central groove of the support frame 5 via a bearing. A support rod 10 is mounted on the support block 9. Sleeves 11 are provided on both sides of the support block 9. The sleeves 11 are rotatably mounted on the support rod 10. The outer wall of the sleeve 11 is made of rubber to increase the friction with the fabric and prevent scratches. The sleeve 11 can rotate freely around the support rod 10. Rollers 12 are provided at both ends of the support rod 10. The correction assembly also includes a ball screw 6, which is rotatably mounted on the support frame 5.

[0026] In this embodiment, one end of the ball screw 6 passes through the fixed frame 1, and a drive source 1 is provided at one end of the ball screw 6. The drive source 1 is mounted on the fixed frame 1 and is equipped with a servo motor. Slider 7 is symmetrically arranged at both ends of the support frame 5. The upper end of the slider 7 is set as an inclined surface 8. The inclined surface 8 contacts the roller 12. The movement of the slider 7 drives the roller 12 to rise and fall through the inclined surface 8, thereby driving the support block 9 to rotate around the bearing, realizing the adjustment of the tilt angle of the sleeve 11 and completing the fabric correction. The contact surface between the inclined surface 8 of the slider 7 and the roller 12 is coated with polytetrafluoroethylene to reduce frictional resistance. At the same time, the roller 12 is embedded with a needle roller bearing to ensure smooth rotation of the support rod 10.

[0027] See Figure 2 , Figure 4 As shown, a jet auxiliary assembly is provided on the support frame 2 13. The jet auxiliary assembly includes a fixing block 14. Multiple fixing blocks 14 are provided. The fixing blocks 14 are equidistantly arranged along the length direction of the support frame 2 13. Both ends of each fixing block 14 are rotatably mounted on the support frame 2 13 through a rotating shaft 15. The fixing block 14 is provided with a nozzle 16.

[0028] In this embodiment, the nozzle 16 is connected to an external air source. Gears 17 are provided on the rotating shafts 15 on the same side. A rack 18 meshes with one side of the gear 17. The rack 18 is slidably disposed with the second support frame 13. A second drive source is provided on the second support frame 13 on the side away from the gear 17. The second drive source is a stepper motor. The second drive source is connected to one of the rotating shafts 15. A housing 19 is provided on the outside of the rack 18 and the gear 17.

[0029] In this embodiment, the outer shell 19 is fixedly connected to the support frame 13 by fixing bolts. The outer shell 19 is made of thin steel plate and is covered on the outside of the gear 17 and rack 18 by fixing bolts. This not only prevents fabric debris from entering the transmission mechanism and affecting accuracy, but also avoids the safety hazards caused by the operator contacting the moving parts.

[0030] The implementation principle is as follows: After the fabric stacking machine starts working, the feed roller 2 at one end of the fixed frame 1 is responsible for conveying the polyester-cotton fabric. At this time, the infrared transmitter 3 and infrared receiver 4 in the detection component start working synchronously. The infrared transmitter 3 continuously transmits infrared signals to the corresponding infrared receiver 4. Once the polyester-cotton fabric deviates during the conveying process, it will block part of the infrared signal. The infrared receiver 4 can then keenly detect this change, thereby detecting the deviated state of the fabric and providing a basis for subsequent correction work.

[0031] When fabric deviation is detected, the correction component begins to function. First, the drive source mounted on the fixed frame 1 is activated, causing the ball screw 6 to rotate. This rotation causes the sliders 7, which are symmetrically arranged at both ends of the support frame 5, to move. The upper end of the slider 7 is provided with an inclined surface 8. When the slider 7 moves, the contact between the inclined surface 8 and the roller 12 causes the roller 12, support rod 10, and support block 9 to rotate. The support rod 10 causes the sleeve 11 to tilt, thereby achieving automatic correction of the polyester-cotton fabric, accurately changing the conveying position of the polyester-cotton fabric, preventing the polyester-cotton fabric from being rolled up crookedly, ensuring product quality and production efficiency, and meeting the requirements of modern large-scale, high-precision production.

[0032] Meanwhile, the jetting auxiliary component also participates in the operation; the external air source is connected to the nozzle 16 on the fixed block 14 to prepare for jetting; the drive source 2 on the support frame 2 13 is started, driving one of the shafts 15 connected to it to rotate. Gears 17 are set on the shafts 15 on the same side. The rotating shaft 15 will drive the gears 17 to rotate. Since the gears 17 and racks 18 mesh with each other, and the racks 18 and support frame 2 13 are slidably set, during the rotation of the gears 17, multiple fixed blocks 14 will be driven to rotate on support frame 2 13 through the shafts 15, so that the nozzles 16 spray gas to act on the polyester-cotton fabric being conveyed; this can eliminate wrinkles caused by static electricity generated by friction between the polyester-cotton fabric and various parts of the equipment during the conveying process, and play a role in smoothing the fabric, effectively improving the flatness of the fabric stacking and ensuring the fabric stacking effect.

[0033] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
