Description

Technical Field

[0001] The utility model relates to the field of cloth production inspection devices, and particularly relates to a simple and rapid cloth inspection device. Background Art

[0002] The cloth inspection operation is a key link in the textile production process, aiming to ensure that the quality of the cloth meets the standard requirements. By using a lamp to illuminate the cloth, the operator can clearly observe the surface of the cloth and timely discover and record defects, such as broken threads, stains, color differences, and uneven fabric density. This process not only helps to improve product quality and reduce the defective rate, but also can identify process problems in the production process at an early stage, so as to make timely adjustments.

[0003] In the prior art, directly illuminating the cloth with a lamp has the problem of uneven light. The area far from the light source is darker, resulting in the operator being unable to comprehensively observe the surface of the cloth, missing small defects or flaws, thus reducing the accuracy and effectiveness of cloth inspection. On the other hand, the scattered light is easily interfered by the ambient light, increasing the visual fatigue during the cloth inspection process. Therefore, we propose a simple and rapid cloth inspection device. Content of the Utility Model

[0004] In order to solve the technical problems existing in the above prior art, the utility model provides a simple and rapid cloth inspection device.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A simple and rapid cloth inspection device includes an upper frame arranged in the vertical direction. A lower frame is installed at the lower end of the upper frame. An upper roller is installed at the upper part of the upper frame. A lower roller misaligned with the upper roller is installed at the lower part of the upper frame. A cloth inspection lamp is installed in the middle of the upper frame. Light guide plates are arranged on both the upper and lower sides of the cloth inspection lamp. The front ends of the light guide plates are slidably assembled in the vertical direction and are in contact with the cloth in the area between the upper roller and the lower roller. The rear ends of the light guide plates are slidably assembled in the horizontal direction and are in contact with the end faces corresponding to the cloth inspection lamp. A light guide area with a variable projection area is formed between the two light guide plates.

[0006] Preferably, a front guide rod is installed at the front part of the side surface of the light guide plate, a rear guide rod is installed at the rear part of the side surface of the light guide plate. Vertical plates are installed on both sides of the light guide plate. The vertical plates are provided with vertical guide grooves in the vertical direction and horizontal guide grooves in the horizontal direction. The front guide rod is slidably assembled in the vertical guide grooves, and the rear guide rod is slidably assembled in the horizontal guide grooves.

[0007] Preferably, the rear ends of the two light guide plates are hinged by a hinge shaft. A connecting block is sleeved on the circumferential surface of the hinge shaft. One end of the connecting block is movably connected with a lead screw. The lead screw is threadedly inserted and installed on a fixed seat. The fixed seat is fixedly installed behind the cloth inspection lamp.

[0008] Preferably, a hook plate is slidably assembled along the width direction of the light guide plate, and a U-shaped groove for the cloth to pass through is arranged on the hook plate.

[0009] Preferably, a tension spring is installed along the width direction of the light guide plate on the hook plate, the other end of the tension spring is installed with a mounting seat, the mounting seat is fixed on the light guide plate, and a hand-tightening screw is inserted through the thread on the hook plate, and the end of the hand-tightening screw is in close contact with the light guide plate.

[0010] Preferably, several support rollers are installed on the upper part of the lower frame, and the several support rollers are distributed in a downwardly concave arc shape.

[0011] Compared with the prior art, the utility model provides a simple and rapid cloth inspection device, which has the following beneficial effects:

[0012] (1) By arranging two light guide plates to block the light emitted by the cloth inspection lamp, an illuminated area is formed between the two light guide plates, and a non-illuminated area is formed outside the two light guide plates, thereby concentrating the eyes of the cloth inspection personnel on the illuminated area. Not only does it reduce the interference of ambient light, but the concentrated light can also increase the contrast between light and dark on the cloth surface, making problems such as fine fiber unevenness, color unevenness, or small holes more obvious, improving the cloth inspection efficiency and quality.

[0013] (2) The distance between the front ends of the two light guide plates is variable, and an illuminated area with different projection areas can be formed, increasing the applicable range.

[0014] (3) The front end of the light guide plate is closely attached to the cloth, reducing the gap between the light guide plate and the cloth, which is conducive to forming an obvious demarcation line on the cloth; the rear end of the light guide plate is closely attached to the cloth inspection lamp, reducing the gap between the cloth inspection lamp and the light guide plate, concentrating the light between the two light guide plates, and improving the brightness of the illuminated area.

[0015] (4) A hook plate is slidably assembled in the width direction of the light guide plate. By adjusting the distance between the U-shaped groove on the hook plate and the light guide plate, the tightness of the cloth can be adjusted. When a defect is found on the cloth, the hook plate fixes the cloth on the light guide plate, facilitating the staff to quickly process the defective area on the cloth, improving the practicability.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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 the embodiments. Usually, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the present invention to be protected, but only represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0026] This embodiment proposes a simple and rapid fabric inspection device, as Figures 1 to 7As shown in the figure, it includes an upper frame 1 arranged vertically. A lower frame 6 is installed at the lower end of the upper frame 1. An upper roller 4 is installed at the upper part of the upper frame 1. A lower roller 5 which is misaligned with the upper roller 4 is installed at the lower part of the upper frame 1. An inspection light 2 is installed in the middle of the upper frame 1. During cloth inspection, one end of the cloth to be inspected is sequentially passed through the outside of the upper roller 4 and the inside of the lower roller 5 and then wound around a cloth roll. The inspection light 2 is turned on. The inspection light 2 emits light and illuminates the cloth. The cloth inspector stands in front of the cloth to observe and complete the cloth inspection operation. In practical applications, due to factors such as the thickness of the cloth and the light conditions at the cloth inspection site, the brightness requirements for the lamp are also different. Although using a lamp with a brightness adjustment function can improve the illumination conditions, the light emitted by the lamp lacks shielding, resulting in a scattered illumination area and an unclear boundary between light and darkness. It is not conducive for the cloth inspector's gaze to focus on the main illuminated area, affecting the work efficiency of the cloth inspector. Therefore, light guide plates 3 are provided on both the upper and lower sides of the inspection light 2. The light guide plates 3 are made of light-impermeable materials. A light guide area is formed between the two light guide plates 3. The light emitted by the inspection light 2 is concentrated in the light guide area and forms an illuminated area on the cloth, while other areas on the cloth cannot form illumination, thereby forming a boundary between light and darkness, which is conducive for the cloth inspector to observe efficiently.

[0027] On the basis of the above solution, in order to further improve the clarity of the boundary between light and darkness, the front end of the light guide plate 3 needs to abut against the cloth to reduce the gap between the light guide plate 3 and the cloth. Therefore, in this embodiment, the front end of the light guide plate 3 contacts the cloth in the area between the upper roller 4 and the lower roller 5. On the other hand, if a gap is generated between the inspection light 2 and the light guide plate 3, the light will disperse from this gap, affecting the brightness on the cloth. Therefore, the rear end of the light guide plate 3 contacts the end face corresponding to the inspection light 2.

[0028] In order to increase the applicable range of this device, the projected area of the light guide area formed between the two light guide plates 3 is variable, that is, the front end of the light guide plate 3 is slidably assembled in the vertical direction and contacts the cloth in the area between the upper roller 4 and the lower roller 5. The rear end of the light guide plate 3 is slidably assembled in the horizontal direction and contacts the end face corresponding to the inspection light 2.

[0029] Specifically, a front guide rod 31 is installed at the front part of the side surface of the light guide plate 3, and a rear guide rod 32 is installed at the rear part of the side surface of the light guide plate 3. Vertical plates 33 are installed on both sides of the light guide plate 3. The vertical plates 33 are provided with vertical guide grooves 34 in the vertical direction and horizontal guide grooves 35 in the horizontal direction. The front guide rod 31 is slidably assembled in the vertical guide groove 34, and the rear guide rod 32 is slidably assembled in the horizontal guide groove 35. When it is necessary to adjust the projected area of the illuminated area, the light guide plate 3 is pushed towards the direction close to the cloth by an external force. Then, the front end of the light guide plate 3 slides vertically along the vertical guide groove 34, and the rear end of the light guide plate 3 slides horizontally along the horizontal guide groove 35, ensuring that a relatively enclosed space is formed among the light guide plate 3, the cloth inspection lamp 2, and the cloth during the whole process, reducing the external scattering of light and forming an illuminated area with a distinct light-dark boundary.

[0030] In the present utility model, a lead screw structure is adopted to drive the movement of the two light guide plates 3. Specifically, the rear ends of the two light guide plates 3 are hinged by a hinge shaft 36. A connecting block 37 is sleeved on the circumferential surface of the hinge shaft 36. One end of the connecting block 37 is movably connected with a lead screw 38. The lead screw 38 is threadedly inserted and installed on a fixed seat 39, and the fixed seat 39 is fixedly installed behind the cloth inspection lamp 2. In this embodiment, taking the example of increasing the projected area of the illuminated area: when the lead screw 38 is rotated forward, the end of the lead screw 38 drives the connecting block 37 to move towards the direction close to the cloth, and the connecting block 37 drives the two light guide plates 3 to move towards the direction close to the cloth. The front ends of the light guide plates 3 move in the vertical direction along the vertical guide groove 34, so that the distance between the front ends of the two light guide plates 3 increases, and the formed illuminated area also increases accordingly.

[0031] During the cloth inspection process, if there are defects on the cloth, it is necessary to fix the defective parts for subsequent processing. Therefore, a hook plate 8 is slidably assembled on the light guide plate 3 along its width direction. The hook plate 8 is provided with a U-shaped groove for the cloth to pass through. The cloth passes through the U-shaped groove. When it is necessary to fix the cloth, the hook plate 8 slides inwards along the width direction of the light guide plate 3, squeezing the cloth against the light guide plate 3, thereby forming the fixation of the cloth.

[0032] Specifically, a tension spring 81 is installed on the hook plate 8 along the width direction of the light guide plate 3. The other end of the tension spring 81 is installed with a mounting seat 82, and the mounting seat 82 is fixed on the light guide plate 3. A hand-tightening screw 83 is threadedly inserted and connected to the hook plate 8, and the end of the hand-tightening screw 83 is in close contact with the light guide plate 3. Due to the pulling force of the tension spring 81, the hook plate 8 has a tendency to move towards the direction close to the light guide plate 3. When the hand-tightening screw 83 is loosened, the hook plate 8 moves inwards under the action of the pulling force of the tension spring 81, squeezing the cloth located in the U-shaped groove against the light guide plate 3 to form the fixation of the cloth.

[0033] In addition, in order to improve the stability of the cloth roll placed on the lower frame 6, in this embodiment, several support rollers 7 are installed on the upper part of the lower frame 6, and the several support rollers 7 are distributed in a downwardly concave arc shape. The cloth roll is supported by the several support rollers 7 distributed in an arc shape, increasing the contact area with the cloth roll and improving the stability of the cloth roll placement.

[0034] It should be noted that during the cloth inspection operation, the cloth roll needs to be rotated manually or mechanically to realize the winding of the cloth, and the cloth inspection operation is completed during the cloth winding process.
