Abstract

This invention relates to the field of textile equipment, specifically to a detection device for an air-jet loom. It includes two sets of support side plates for support, with support guide rollers rotatably engaged at the inner end faces of the two sets of support side plates, and fixed guide rollers rotatably engaged at the inner end faces of the two sets of support side plates near the support guide rollers. By incorporating an adjustable detection device and a fixed detection device, this invention allows for rapid preliminary detection of the fabric between the limiting guide roller and the unwinding guide roller during detection. Simultaneously, a stepper motor drives a driven gear and a threaded rotating sleeve via a drive gear, causing the threaded rotating sleeve to drive a support slide plate and lighting strips to adhere to the detected fabric via a threaded guide shaft.

Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, specifically to a testing device for an air-jet loom. Background Technology

[0002] Air-jet looms utilize high-speed airflow for weft insertion, which can effectively improve weaving speed and production efficiency. At the same time, air-jet looms use air as the weft insertion medium, resulting in lower energy consumption and more environmentally friendly emissions compared to traditional shuttle looms and water looms.

[0003] For example, the utility model patent with publication number CN208654051U discloses a fabric hole detection device for an air-jet loom. The device includes a frame, a take-up shaft, a reflector on the inner side of the take-up shaft, a fixed frame connected to the front side of the frame, and a slide rail containing a slider connected to a drive device. A light source is located at the top of the slide rail, illuminating the reflector. The slide rail has an elongated hole, and a cylindrical strip is connected to the side of the slider away from the drive device, extending through the elongated hole. A light sensor is connected to the other end of the cylindrical strip, positioned on the side where the slide rail connects to a horizontal bar, and moves with the slider. This utility model allows for simultaneous take-up and detection, reducing processes, increasing weaving efficiency, and lowering labor costs. Simultaneously, manually controlling the light sensor to move back and forth ensures detection accuracy and prevents missed holes.

[0004] Although the above-mentioned equipment can perform inspection operations on textile fabrics, the degree of automation in the fabric inspection is insufficient. In addition, relying on a single inspection can easily lead to missed detection of fabric holes, thereby reducing the accuracy of the inspection. Therefore, an air-jet loom is needed to cooperate with the inspection equipment to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a detection device for an air-jet loom to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a testing device for an air-jet loom, comprising two sets of support side plates for support, a support guide roller rotatably engaged at the front of the inner end face of the two sets of support side plates, and a fixed guide roller rotatably engaged at the inner end face of the two sets of support side plates near the support guide roller, and two sets of guide sliding shafts provided at the middle of the inner end face of each of the two sets of support side plates.

[0007] An adjustment device is fixedly installed at the middle of the inner end face of the two sets of support side plates;

[0008] A limiting guide roller is rotatably engaged with the inner end face of the support side plate near the rear of the adjustment device. An unwinding guide roller is rotatably engaged at the tail of the two sets of support side plates, and a servo motor is provided at the side end face of the support side plate directly opposite the unwinding guide roller.

[0009] A fixed detection device is fixedly installed at the rear of the two sets of support side plates, and the fixed detection device is located at the middle of the limiting guide roller and the unwinding guide roller;

[0010] An adjustable detection device is fixedly installed at the front of the two sets of support side plates, and the adjustable detection device is located in the middle of the support guide roller and the fixed guide roller.

[0011] Preferably, the adjustable detection device includes a support base plate. Three sets of first photosensitive receivers are equidistantly arranged at the center of the upper end surface of the support base plate. A support bracket is arranged on the upper end surface of the support base plate, directly opposite the first photosensitive receivers. A threaded sleeve is rotatably engaged at the center of the upper end surface of the support bracket. A driven gear is arranged at the center of the lower end surface of the threaded sleeve. A stepper motor is arranged on the upper end surface of the support bracket near the front of the threaded sleeve. A driving gear is arranged at the output end of the stepper motor. A threaded guide shaft is threadedly connected to the inner end surface of the support bracket through the threaded sleeve. A support slide plate is arranged at the center of the lower end surface of the threaded guide shaft. Three sets of lighting strips are equidistantly arranged on the lower end surface of the support slide plate.

[0012] Preferably, the fixed detection device includes a limiting base plate, a second photosensitive receiver is fixedly disposed on the upper end surface of the limiting base plate, and a fixed bracket is disposed on the upper end surface of the limiting base plate directly opposite the second photosensitive receiver. Detection light sources are disposed at equal intervals on the top of the inner end surface of the fixed bracket, and a positioning lamp cover is disposed on the top of the inner end surface of the fixed bracket near the outside of the detection light source.

[0013] Preferably, the adjusting device includes a connecting guide seat, the inner end face of which is rotatably engaged with two sets of synchronous pulleys, and the two sets of synchronous pulleys are meshed and connected by a synchronous belt. A connecting screw is fixedly installed inside the two sets of synchronous pulleys, and a reduction motor is installed on the upper end face of the connecting guide seat opposite to the connecting screw. The lower end face of the connecting guide seat is threaded with two sets of ball bearing slides through the connecting screw, and a limit groove is opened on the inner end face of each set of ball bearing slides. A pressure guide roller is rotatably engaged on the inner end face of each set of ball bearing slides.

[0014] Preferably, the support guide roller, limiting guide roller, fixed guide roller, and unwinding guide roller are aligned in a straight line. The first photosensitive receiver is located near the top radially of the support guide roller and the fixed guide roller, and the second photosensitive receiver is located near the top radially of the limiting guide roller and the unwinding guide roller. The fabric passes through the top of the support guide roller and the fixed guide roller, and then through the bottom of the pressing guide roller, before passing through the top of the limiting guide roller and the unwinding guide roller. The first and second photosensitive receivers are located near the bottom of the fabric, which improves the stability of subsequent detection.

[0015] Preferably, the driven gear meshes with the driving gear, and the support slide plate slides into the interior of the support bracket, providing sufficient guidance and limiting basis for the subsequent sliding of the support slide plate inside the support bracket.

[0016] Preferably, the side of the pressing guide roller is symmetrically provided with snap-fit ​​connectors, and both the snap-fit ​​connectors and the limiting rotating grooves are T-shaped. The pressing guide roller is rotatably snapped into the ball bearing slide through the snap-fit ​​connectors, which can effectively improve the stability of the subsequent rotation and limiting of the pressing guide roller inside the ball bearing slide, thereby improving the stability of subsequent control of the fabric tension.

[0017] Preferably, the ball bearing slide is slidably engaged with the inner end face of the support side plate via the guide slide shaft, which can effectively improve the stability of the subsequent vertical sliding displacement of the ball bearing slide inside the support side plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This invention, by setting up an adjustable detection device and a fixed detection device, allows the detection light source and the second photosensitive receiver to perform a rapid preliminary detection operation on the fabric between the limiting guide roller and the unwinding guide roller during detection. At the same time, the stepper motor drives the driven gear and the threaded rotating sleeve to rotate through the active gear, so that the threaded rotating sleeve can drive the support slide plate and the lighting strip to adhere to the detected fabric through the threaded guide shaft. This allows the three sets of lighting strips to work with the three sets of first photosensitive receivers to perform all-round adhesion detection on the outgoing fabric, effectively improving the accuracy of detecting fabric holes.

[0020] 2. By setting an adjustment device, the present invention can control the tension of the fabric during testing. The reduction motor can drive two sets of connecting screws to rotate synchronously through the synchronous pulley and synchronous belt. The two sets of connecting screws can then drive the ball bearing slide to move down synchronously, thereby enabling the pressing guide roller to press or loosen the fabric. This facilitates the control of the tension of the tested fabric and improves the accuracy of subsequent testing. Attached Figure Description

A positioning lamp cover 31 is provided on the top of the inner end surface of the fixed bracket 32, close to the outside of the detection light source 35.

[0041] The adjusting device 5 includes a connecting guide seat 52. Two sets of synchronous pulleys 53 are rotatably engaged on the inner end face of the connecting guide seat 52, and are meshed between the two sets of synchronous pulleys 53 by a synchronous belt 54. A connecting screw 55 is fixedly installed inside the two sets of synchronous pulleys 53, and a reduction motor 51 is installed on the upper end face of the connecting guide seat 52 opposite to the connecting screw 55. Two sets of ball bearing slides 56 are threadedly connected to the lower end face of the connecting guide seat 52 through the connecting screw 55, and a limit groove 57 is opened on the inner end face of each set of ball bearing slides 56. A pressure guide roller 58 is rotatably engaged on the inner end face of each set of ball bearing slides 56.

[0042] The support guide roller 1, the limiting guide roller 6, the fixed guide roller 9, and the unwinding guide roller 10 are aligned in a straight line. The first photosensitive receiver 22 is located near the top of the radial direction of the support guide roller 1 and the fixed guide roller 9, and the second photosensitive receiver 34 is located near the top of the radial direction of the limiting guide roller 6 and the unwinding guide roller 10. The fabric passes through the top of the support guide roller 1 and the fixed guide roller 9, and then through the bottom of the pressing guide roller 58, before passing through the top of the limiting guide roller 6 and the unwinding guide roller 10. The first photosensitive receiver 22 and the second photosensitive receiver 34 are located near the bottom of the fabric, which can improve the stability of subsequent detection.

[0043] Driven gear 26 meshes with driving gear 27, and support plate 25 slides and engages with the inside of support bracket 21, providing sufficient guidance and limiting basis for subsequent sliding of support plate 25 inside support bracket 21.

[0044] The side of the pressing guide roller 58 is symmetrically provided with snap-fit ​​joints, and both the snap-fit ​​joints and the limiting rotation groove 57 are T-shaped. The pressing guide roller 58 is rotatably snapped into the ball bearing slide 56 through the snap-fit ​​joints, which can effectively improve the stability of the subsequent rotation limit of the pressing guide roller 58 in the ball bearing slide 56, thereby improving the stability of subsequent control of the fabric tension.

[0045] The ball bearing slide 56 is slidably engaged with the inner end face of the support side plate 8 via the guide slide shaft 4, which can effectively improve the stability of the subsequent up and down sliding displacement of the ball bearing slide 56 inside the support side plate 8.

[0046] Working principle: Before use, the user can pass the fabric to be tested through the upper part of the unwinding guide roller 10 and the limiting guide roller 6, and then pass the fabric through the lower part of the pressing guide roller 58. Finally, the fabric is discharged through the upper part of the supporting guide roller 1 and the fixed guide roller 9. When detecting various holes and gaps on the outside of the textile fabric, the detection light source 35 first projects the detection light through the limiting of the positioning lamp cover 31 onto the upper part of the fabric. Then, the second light sensor 34 located at the bottom of the fabric can sense the light passing through the holes or gaps in the fabric, and then identify whether the holes and gaps in the fabric meet the detection standards. If they meet the standards, the fabric continues to be fed; otherwise, the feeding stops. When performing a second detection on the fabric, the user can first adjust the distance between the lighting strip 24 and the fabric. During adjustment, the stepper motor 28 can... The drive gear 27 drives the driven gear 26 and the threaded sleeve 210 to rotate, so that the threaded sleeve 210 can drive the support slide plate 25 and the lighting strip 24 to move down through the threaded guide shaft 29 until the lighting strip 24 is in contact with the fabric to be tested. Then, the three sets of lighting strips 24 can work with the three sets of first photosensitive receivers 22 at the bottom of the fabric to perform all-round contact testing on the fabric. If it is necessary to adjust the tension of the tested fabric, the geared motor 51 can drive the two sets of connecting screws 55 to rotate synchronously through the synchronous pulley 53 and the synchronous belt 54. The two sets of connecting screws 55 can drive the ball slide 56 to move down or up synchronously, so that the pressing guide roller 58 can press or loosen the fabric to prevent the fabric from being too loose or too tight in subsequent testing, which would affect the testing stability.
