[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Example 1, please refer to Figures 1-4 A new visual inspection device for printing and dyeing defects in fabrics, comprising: The visual inspection chamber 100 has a vertical rod 200 driven by a linear motor mounted on its top, a movable plate 300 mounted on its bottom, and an inspection probe 400 mounted on its bottom. The visual inspection chamber 100 is equipped with a rotating drum 501 driven by a servo motor. The roll of fabric to be inspected is fed into the visual inspection chamber 100 by a conveying device, and the servo motor and the inspection probe 400 are activated to drive the rotating drum 501 driven by the servo motor to rotate rapidly.

[0027] The rotating cylinder 501 is equipped with a placement chamber 502. When the rotating cylinder 501 rotates rapidly, the rapidly rotating cylinder 501 can drive the placement chamber 502, which is fixedly connected to it, to rotate rapidly as well.

[0028] A vertical plate 507 is slidably connected to the top of the placement chamber 502. A transmission component for transmission is assembled between the placement chamber 502 and the vertical plate 507. The transmission component includes an elastic telescopic plate 503 assembled on the inner wall of the placement chamber 502. A pressure plate 504 is assembled on the side of the elastic telescopic plate 503. The pressure plate 504 is located inside the placement chamber 502 and is slidably connected to the placement chamber 502. An air pressure chamber 505 is assembled inside the placement chamber 502. The vertical plate 507 passes through the air pressure chamber 505 and is slidably connected to the air pressure chamber 505 by a piston. An air bladder 506 communicating with the air pressure chamber 505 is assembled on the side of the air pressure chamber 505. An arc-shaped plate 508 is fixedly connected to the top of the vertical plate 507. When the curved plate 508 moves, it moves synchronously a certain distance along with the placement chamber 502, providing a certain degree of support for the fabric conveyed to the visual inspection chamber 100. The inspection probe 400 can then perform corresponding visual inspection operations on the fabric at that location, thereby improving the accuracy of the inspection results.

[0029] In use, the rolled fabric to be inspected is fed into the visual inspection chamber 100 via a conveying device. The servo motor and inspection probe 400 are activated, causing the rotating drum 501, driven by the servo motor, to rotate rapidly. The rapidly rotating drum 501, in turn, causes the placement chamber 502, which is fixedly connected to it, to rotate rapidly as well. As the placement chamber 502 rotates rapidly, the pressure plate 504 inside stretches the elastic telescopic plate 503 under centrifugal force, and moves along the inner wall of the placement chamber 502. With the movement of the pressure plate 504, the airbag 506 is compressed. The airbag 506 contains gas and is connected to the air pressure chamber 505, so that when the airbag 506 is compressed by the pressure plate 504… The gas stored in the airbag 506 flows into the air pressure chamber 505, thereby squeezing the gas originally stored in the air pressure chamber 505. This causes the gas in the air pressure chamber 505 to flow towards the side closer to the vertical plate 507, which drives the vertical plate 507, which is slidably connected to the air pressure chamber 505 via a piston, to move out of the air pressure chamber 505. The moving vertical plate 507 can then drive the arc plate 508, which is fixedly connected to it, to move. This causes the arc plate 508, which rotates with the placement chamber 502, to move a certain distance synchronously, providing a certain degree of support for the fabric delivered to the visual inspection chamber 100. The inspection probe 400 can then perform the corresponding visual inspection operation on the fabric at that location.

[0030] Example 2, please refer to Figures 1-6Based on Embodiment 1, the visual inspection chamber 100 is internally equipped with an auxiliary restraint component 600, which includes a pressing plate 601 mounted on the side of the moving plate 300. When further inspection of the fabric is required, a linear motor is activated, driving the vertical rod 200 and the moving plate 300 driven by the linear motor to move downwards. The moving plate 300 then drives the inspection probe 400 mounted at its bottom to move downwards, closer to the fabric to be inspected. As the moving plate 300 moves, the pressing plate 601, which is fixedly connected to the moving plate 300, moves downwards along with it.

[0031] The visual inspection chamber 100 is equipped with a hydraulic chamber 602 on its side. The top of the hydraulic chamber 602 is slidably connected to a force-bearing rod 603 via a piston. A spring 604 is mounted on the side of the force-bearing rod 603. When the extrusion plate 601 moves downward, it can extrude force to the force-bearing rod 603. The force-bearing rod 603 is compressed, which in turn compresses the spring 604 and moves downward.

[0032] The rotating cylinder 501 houses a second hydraulic chamber 605, which is rotatably connected to the side of a first hydraulic chamber 602 and communicates with it. A hydraulic hose 606 is fitted to the outside of the second hydraulic chamber 605. A third hydraulic chamber 607 is fitted to the side of the arc-shaped plate 508. The end of the hydraulic hose 606 furthest from the second hydraulic chamber 605 is fitted to the side of the third hydraulic chamber 607 and communicates with it. A transmission plate 608 is slidably connected to the side of the third hydraulic chamber 607 via a piston. An auxiliary limiting plate 610 is rotatably connected to the side of the arc-shaped plate 508 via a rotating shaft 609. When the transmission plate 608 moves out of the third hydraulic chamber 607, the moving transmission plate 608 drives the fixedly connected auxiliary limiting plate 610 to rotate at a certain angle, thereby extending the arc-shaped plate 508 and further improving the device's support effect on the fabric, thus further improving the accuracy of the detection results.

[0033] In use, based on Example 1, when further testing of the fabric is required, the linear motor is activated, driving the vertical rod 200 and the moving plate 300 driven by the linear motor to move downwards. The moving plate 300 then moves the detection probe 400 mounted at its bottom downwards, closer to the fabric to be tested. As the moving plate 300 moves, the pressing plate 601, which is fixedly connected to the moving plate 300, moves downwards together. The downward-moving pressing plate 601 presses the force rod 603. The force rod 603, under pressure, compresses the spring 604 and moves downwards. In conjunction with the hydraulic chamber 602, which is slidably connected to the force rod 603 via a piston, the force rod 603, during its downward movement, compresses the oil originally stored in the hydraulic chamber 602. The oil, under pressure, flows into the hydraulic chamber 605, which is rotatably connected to the hydraulic chamber 602. The movement of the hydraulic plate 601 squeezes the oil in hydraulic chamber 2 605, causing some of the oil in hydraulic chamber 2 605 to flow into the hydraulic hose 606 connected to it. This causes some of the oil in hydraulic hose 606 to flow into hydraulic chamber 3 607 connected to it, pushing the oil originally stored in hydraulic chamber 3 607. The oil then flows towards the side closer to the transmission plate 608, causing the transmission plate 608, which is slidably connected to hydraulic chamber 3 607 via a piston, to move out of hydraulic chamber 3 607. The moving transmission plate 608 can then drive the auxiliary limiting plate 610, which is fixedly connected to it, to rotate at a certain angle, thereby extending the arc plate 508. After further testing is completed, the squeezing plate 601 returns to its original position along with the moving plate 300. The force rod 603 loses its restriction and can return to its original position under the action of spring 1 604. Similarly, the auxiliary limiting component 600 returns to its original position.

[0034] Example 3, please refer to Figures 1-8 Based on Embodiments 1 and 2, the visual inspection chamber 100 is equipped with a collection component 700, which includes a bevel gear 701 mounted on the outside of the hydraulic chamber 605. When the hydraulic chamber 605 rotates with the rotating cylinder 501, it can drive the bevel gear 701 mounted on the outside of the rotating cylinder 501 to rotate.

[0035] A rotating rod 702 is rotatably connected to the side of the visual inspection chamber 100. A second bevel gear 703 and a first sprocket 704 are fixedly connected to the outer side of the rotating rod 702. The second bevel gear 703 meshes with the first bevel gear 701. When the first bevel gear 701 rotates, it drives the second bevel gear 703, which meshes with it, to rotate. The rotating bevel gear 703, in turn, drives the rotating rod 702, which is fixedly connected to it, to rotate.

[0036] A chain 705 is mounted on the outer side of sprocket 1 704. A reciprocating screw 706 is rotatably connected to the side of the vision inspection chamber 100. A sprocket 2 707 is fixedly connected to the outer side of the reciprocating screw 706. The end of the chain 705 away from sprocket 1 704 is mounted on the outer side of sprocket 2 707. A cleaning brush 708 is threadedly connected to the outer side of the reciprocating screw 706. The cleaning brush 708 passes through the vision inspection chamber 100 and is slidably connected to it. A collection chamber 709 is mounted at the bottom of the vision inspection chamber 100. When the reciprocating screw 706 rotates, it drives the cleaning brush 708 to move back and forth in the horizontal direction, sweeping fabric debris from the inner wall of the vision inspection chamber 100 into the collection chamber 709, making the device easier to use.

[0037] In use, based on Embodiments 1 and 2, when the hydraulic chamber 2 605 rotates with the rotating cylinder 501, it drives the bevel gear 1 701 mounted on the outside of the rotating cylinder 501 to rotate, causing the bevel gear 1 701 to drive the bevel gear 2 703 meshing with it to rotate. The rotating bevel gear 2 703, in a rotating state, drives the rotating rod 702 fixedly connected to it to rotate, causing the rotating rod 702 to drive the sprocket 1 704 fixedly connected to it to rotate, cooperating with the chain 70 mounted on the outside of the sprocket 1 704. 5. This causes the second sprocket 707, which is connected to the first sprocket 704 via the chain 705, to rotate. The rotating sprocket 707 drives the reciprocating screw 706, which is fixedly connected to it, to rotate. Meanwhile, the cleaning brush 708, which is threaded onto the outside of the reciprocating screw 706, is restricted by the visual inspection chamber 100, which is slidably connected to it. As the reciprocating screw 706 rotates, the cleaning brush 708 moves back and forth in the horizontal direction, sweeping the fabric debris on the inner wall of the visual inspection chamber 100 into the collection chamber 709.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
