Detailed Embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Embodiment 1 Please refer to Figures 1 - 4 , a defect detection device for processing woolen fabrics, including a fabric detection frame 100. A servo motor 200 is assembled on the side of the fabric detection frame 100. A fabric storage roller 300 and a winding roller 400 are respectively driven and connected to the side of the servo motor 200. A guide roller 500 is fixedly connected inside the fabric detection frame 100. Starting the servo motor 200 can respectively drive the fabric storage roller 300 and the winding roller 400 connected to it to rotate, so as to Figure 4 viewed from the perspective in, both the fabric storage roller 300 and the winding roller 400 are in a counterclockwise rotation state. When the fabric storage roller 300 rotates counterclockwise, the fabric on it is conveyed out. The fabric passes through multiple guide rollers 500 and is then wound by the winding roller 400; A first sprocket 601 is driven and connected to the outside of the fabric storage roller 300. A chain 602 is assembled on the outside of the first sprocket 601. A fixed seat 603 is fixedly connected to the top of the fabric detection frame 100. A reciprocating lead screw 604 is rotatably connected inside the fixed seat 603. A second sprocket 605 is fixedly connected to the outside of the reciprocating lead screw 604. One end of the chain 602 away from the first sprocket 601 is assembled at the outside position of the second sprocket 605. A sliding block 606 is connected to the outside of the reciprocating lead screw 604 through a threaded connection. The sliding block 606 is slidably connected to the fixed seat 603. When the fabric storage roller 300 rotates, it can synchronously drive the first sprocket 601 connected to it to rotate. With the cooperation of the chain 602 assembled on the outside of the first sprocket 601, the second sprocket 605 driven and connected to the first sprocket 601 through the chain 602 rotates synchronously. The second sprocket 605 drives the reciprocating lead screw 604 fixedly connected to it to rotate. Because the sliding block 606 is restricted by the fixed seat 603 slidably connected to it, the sliding block 606 moves reciprocally on the reciprocating lead screw 604.

[0019] A fixed frame 607 is fixedly connected to the bottom of the sliding block 606. A defect camera detector 608 is assembled inside the fixed frame 607. There are two groups of defect camera detectors 608, and they are distributed at the top and bottom positions of the fabric. When the sliding block 606 moves reciprocally on the reciprocating lead screw 604, it can drive the fixed frame 607 fixedly connected to it to move, so that the fixed frame 607 drives the two groups of multiple defect camera detectors 608 assembled inside it to move reciprocally. The multiple defect camera detectors 608 located at the top and bottom positions of the fabric respectively perform repeated detections on the fabric, improving the accuracy of the detection results of the device and making the device more convenient for detection.

[0020] After completing the defect detection operation on all fabrics, remove the fabric from the winding roller 400, and then start the servo motor 200 to drive the fabric storage roller 300 and the winding roller 400 connected to it by transmission to rotate clockwise for reset. Similarly, the reciprocating screw rod 604, the sliding block 606, the fixing bracket 607, and multiple groups of defect cameras 608 are completely reset to facilitate the next use of the device. The interior of the fabric detection frame 100 is respectively equipped with a pressing component 700 and an extrusion component 800 for maintaining the winding effect of the fabric.

[0021] During use, start the servo motor 200 to drive the fabric storage roller 300 and the winding roller 400 connected to it by transmission to rotate respectively, so as to Figure 4 From the perspective in the figure, both the fabric storage roller 300 and the winding roller 400 are in a counterclockwise rotation state. When the fabric storage roller 300 rotates counterclockwise, the fabric on it is conveyed out, and the fabric passes through multiple guide rollers 500 and is then wound by the winding roller 400; the rotating fabric storage roller 300 synchronously drives the first sprocket 601 connected to it by transmission to rotate. Cooperating with the chain 602 assembled outside the first sprocket 601, the second sprocket 605 connected to the first sprocket 601 by the chain 602 rotates synchronously. The second sprocket 605 drives the reciprocating screw rod 604 connected to it fixedly to rotate. Because the sliding block 606 is restricted by the fixed seat 603 slidably connected to it, the sliding block 606 moves reciprocally on the reciprocating screw rod 604. The sliding block 606 drives the fixing bracket 607 connected to it fixedly to move, so that the fixing bracket 607 drives two groups of multiple defect cameras 608 assembled inside it to move reciprocally. Multiple defect cameras 608 located at the top and bottom positions of the fabric respectively detect the fabric repeatedly in sequence; after completing the defect detection operation on all fabrics, remove the fabric from the winding roller 400, and then start the servo motor 200 to drive the fabric storage roller 300 and the winding roller 400 connected to it by transmission to rotate clockwise for reset. Similarly, the reciprocating screw rod 604, the sliding block 606, the fixing bracket 607, and multiple groups of defect cameras 608 are completely reset.

[0022] Embodiment 2 Please refer to Figures 1 - 6 Based on Embodiment 1, the pressing component 700 includes a first hydraulic chamber 701, and a threaded disk 702 is connected to the side of the reciprocating screw rod 604 by transmission. When the reciprocating screw rod 604 rotates, it can drive the threaded disk 702 connected to it by transmission to rotate, so as to Figure 6In the perspective view, the threaded disc 702 is in a counterclockwise rotation state. The side of the threaded disc 702 is threadedly connected with a threaded block 703 through the setting of threads. The side of the threaded block 703 is fixedly connected with a sliding rod 704. The sliding rod 704 is located at the side position of the fabric detection frame 100 and is in a sliding connection state with the fabric detection frame 100. When the threaded disc 702 is in a counterclockwise rotation state, because the threaded block 703 is fixedly connected with the sliding rod 704, and the sliding rod 704 is in a sliding connection state with the fabric detection frame 100, when the threaded block 703 is restricted by the fabric detection frame 100, the threaded block 703 moves upward in the vertical direction.

[0023] One end of the hydraulic chamber 701 is slidably connected with a transmission rod 705. The transmission rod 705 is located at the side position of the threaded block 703 and is in a fixed state with the threaded block 703. The other end of the hydraulic chamber 701 is slidably connected with a pull rod 706. The side of the pull rod 706 is fixedly connected with an arc-shaped plate 707. When the threaded block 703 moves upward in the vertical direction, it can drive the transmission rod 705 fixedly connected with the threaded block 703 to move upward. Cooperating with the hydraulic chamber 701 slidably connected with the transmission rod 705, the pressure in the hydraulic chamber 701 is reduced, driving the pull rod 706 slidably connected with the hydraulic chamber 701 to move to the side away from the winding roller 400, so that the pull rod 706 drives the arc-shaped plate 707 fixedly connected with it to move to the side away from the winding roller 400, and corresponding pressing operations are performed on the fabrics thickening in sequence on the winding roller 400, improving the winding effect of the device on the fabrics that have completed detection.

[0024] When the reciprocating lead screw 604 is reset, similarly, the threaded block 703 can be reset, thereby driving the arc-shaped plate 707 to reset. At this time, the pressing assembly 700 is in a fully reset state, facilitating the next use of the pressing assembly 700.

[0025] During use, on the basis of Embodiment 1, when the reciprocating lead screw 604 rotates, it can drive the threaded disc 702 connected to it through transmission to rotate, so as to Figure 6In the perspective observation, the threaded disk 702 is in a counterclockwise rotation state. Since the threaded block 703 is fixedly connected to the sliding rod 704, and the sliding rod 704 is in a sliding connection state with the fabric detection frame 100, when the threaded block 703 is restricted by the fabric detection frame 100, the threaded block 703 moves upward in the vertical direction, driving the transmission rod 705 fixedly connected to the threaded block 703 to move upward. Cooperating with the hydraulic chamber 701 that is slidably connected to the transmission rod 705, the pressure in the hydraulic chamber 701 is reduced, driving the pull rod 706 that is slidably connected to the hydraulic chamber 701 to move to the side away from the winding roller 400, so that the pull rod 706 drives the arc-shaped plate 707 fixedly connected thereto to move to the side away from the winding roller 400, and corresponding pressing operations are performed on the fabrics with increasing thickness on the winding roller 400; when the reciprocating lead screw 604 is reset, similarly, the threaded block 703 can be reset, thereby driving the arc-shaped plate 707 to reset. At this time, the pressing assembly 700 is in a fully reset state.

[0026] Embodiment III Please refer to Figures 1 - 8 , on the basis of Embodiment I and Embodiment II, the extrusion assembly 800 includes a hydraulic chamber 801. One end of the hydraulic chamber 801 is slidably connected with a force-receiving rod 802. The force-receiving rod 802 is located at the top of the transmission rod 705 and is fixed to the transmission rod 705. When the transmission rod 705 moves upward, it can drive the force-receiving rod 802 fixedly connected thereto to move upward synchronously. Cooperating with the hydraulic chamber 801 that is slidably connected to the force-receiving rod 802, the pressure in the hydraulic chamber 801 increases.

[0027] The other end of the hydraulic chamber 801 is slidably connected with a push rod 803. The side of the push rod 803 is fixedly connected with an arc-shaped plate 804. When the pressure in the hydraulic chamber 801 increases, it can drive the push rod 803 that is slidably connected to the hydraulic chamber 801 to move. The push rod 803 moves to the side close to the fabric storage roller 300, so that the push rod 803 drives the arc-shaped plate 804 fixedly connected thereto to move to the side close to the fabric storage roller 300, and corresponding extrusion operations are performed on the fabrics with decreasing thickness on the fabric storage roller 300, reducing the possibility of the fabric coming off the fabric storage roller 300 and making the entire detection process more stable.

[0028] When the threaded block 703 is fully reset, the force-receiving rod 802 connected to it through the transmission rod 705 is fully reset. Similarly, the arc-shaped plate 804 is reset. At this time, the extrusion assembly 800 is in a fully reset state, facilitating the next use of the extrusion assembly 800.

[0029] In use, on the basis of the first and second embodiments, when the transmission rod 705 moves upward, it can drive the force-receiving rod 802 fixedly connected thereto to move upward synchronously. In cooperation with the second hydraulic chamber 801 slidably connected to the force-receiving rod 802, the pressure in the second hydraulic chamber 801 is increased, driving the push rod 803 slidably connected to the second hydraulic chamber 801 to move. The push rod 803 moves toward the side close to the fabric storage roller 300, so that the push rod 803 drives the second arc-shaped plate 804 fixedly connected thereto to move toward the side close to the fabric storage roller 300, and corresponding extrusion operations are performed on the fabric gradually decreasing on the fabric storage roller 300. When the threaded block 703 is completely reset, the force-receiving rod 802 connected to it through the transmission rod 705 is completely reset. Similarly, the second arc-shaped plate 804 is reset. At this time, the extrusion assembly 800 is in a completely reset state.

[0030] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
