Description

Technical Field

[0001] This invention belongs to the field of fabric testing technology, and in particular relates to a double-sided fabric testing device. Background Technology

[0002] Currently, in the hotel and other accommodation industries, a large number of bed sheets and other fabrics are changed daily. These sheets require bulk processing, including washing, steam ironing, and folding. To ensure fabric quality, inspection for stains, holes, burns, etc., is necessary before folding. Current inspection methods mostly involve:

[0003] 1. The manual visual observation method is labor-intensive, inefficient, labor-intensive, and costly.

[0004] 2. While single-sided inspection during fabric conveying can reduce manual intervention, it requires additional steps of changing the fabric and secondary conveying inspection, resulting in low work efficiency. Alternatively, using intermittent conveying for double-sided inspection also results in low work efficiency.

[0005] 3. The fabric conveying process after steam ironing is a pull-type process. Pulling will cause wrinkles in the fabric during conveying, affecting the comprehensiveness and accuracy of the inspection. At the same time, it will affect the smoothness of conveying for fabrics with high humidity. Summary of the Invention

[0011] As a further improvement, the support rod is a square tube; the guide strip is integrally formed on the guide plate, and the guide plate is provided with fitting holes for fitting with the support rod.

[0012] As a further improvement, the fabric support mechanism includes a bracket, on which a support rod with an arc surface is provided, which is located close to the transparent detection plate;

[0015] As an improvement, the frame is provided with two lamp holders, which are distributed on both sides of the transparent detection plate, and each lamp holder is provided with a supplementary light.

[0016] As a further improvement, the lamp holder, the transparent detection plate, and the support pole for mounting the camera assembly are all provided with adjustment plates at both ends. The adjustment plates are mounted on the frame and are provided with arc-shaped adjustment holes and mounting holes. A first connector passes through both the arc-shaped adjustment holes and the mounting holes, and the first connector is connected to the frame.

[0017] As a further improvement, the adjustment plates at both ends of the transparent detection plate are mounted on adjustment seats, which are provided with vertical adjustment elongated holes and are installed on the frame.

[0018] As a further improvement, both ends of the fixed beam are provided with adjustment frames fixed to the bracket, the adjustment frames are provided with arc-shaped waist holes, and a second connecting piece passing through the arc-shaped waist holes is provided between the adjustment frames and the fixed beam.

[0019] As a further improvement, both ends of the support rod are provided with rod seats;

[0020] Both ends of the bracket are provided with a support base;

[0021] The linear power element is mounted on the mounting base and connected to the frame;

[0022] The mounting base and the rod base are mounted on the frame, and the mounting base, the rod base, and the bracket and the frame base are all provided with straightness adjustment mounting holes.

[0023] After adopting the above technical solution, the effect of the present invention is as follows:

[0024] The fabric double-sided inspection device includes a frame with a belt roller rotatably mounted on it. Multiple conveyor belts are wound around the belt roller along its length. A discharge rack is located downstream of the belt roller, and a fabric pressing mechanism is located above the discharge rack. A transparent inspection plate is located on the frame between the discharge rack and the belt roller. Multiple camera assemblies are also mounted on the frame, distributed on both sides of the transparent inspection plate with their lenses facing it. An air blowing mechanism is located upstream of the transparent inspection plate, with its blowing end facing the fabric pressing mechanism. A fabric guiding mechanism is located upstream of the belt roller, and multiple guide bodies on the fabric guiding mechanism pass through… Between two adjacent conveyor belts and extending above the transparent inspection plate, based on the above structure, the fabric double-sided inspection device transports the steam-ironed fabric through multiple conveyor belts driven by belt rollers. During this transport, the fabric is guided to the transparent inspection plate by the fabric guiding mechanism. After that, the fabric passes through the fabric pressing mechanism and enters the discharge rack for transport. During the above process, the air blowing mechanism blows air towards the fabric pressing mechanism to dry and flatten the fabric, improving its smoothness. At the same time, camera components distributed on both sides of the transparent inspection plate continuously take pictures of both sides of the fabric and judge whether there are stains, holes, burns, etc.

[0025] In summary, the use of this double-sided fabric inspection device enables online monitoring of both sides of the fabric during transport, ensuring the continuity of fabric transport and effectively improving fabric inspection efficiency. Simultaneously, the blowing and pressing of the fabric during the photographic inspection process ensures the flatness and smoothness of the fabric during transport, thereby effectively improving the comprehensiveness and accuracy of the inspection.

[0026] Because the fabric guiding mechanism includes a support rod mounted on the frame, and multiple guide strips arranged sequentially along the length of the support rod, each guide strip is located between two adjacent conveyor belts and extends towards the transparent detection plate. The guide strip corresponding to the position of the belt roller is set higher than the conveyor belt. Thus, during the conveying of the conveyor belt, the fabric is lifted from the conveyor belt by the guide strips and continuously guided to the transparent detection plate. This not only improves the connection between the conveyor belt and the transparent detection plate, but also improves the smoothness of the fabric conveying between the two, ensuring the continuous and smooth conveying of the fabric.

[0027] Because the support rod is a square tube, and the guide strip is integrally formed on the guide plate, the guide plate has fitting holes for fitting the support rod. This structure facilitates the improvement of the reliability and stability of the fit between the support rod and the guide plate, and also helps to improve assembly efficiency.

[0028] The fabric pressing mechanism includes a support frame with a curved pressing rod positioned close to the transparent detection plate. Both ends of the support frame are driven by linear power elements, which are vertically mounted on the frame. The working height of the pressing rod on the support frame is adjusted by the linear power elements. During transport, the pressing rod is used to press and flatten the fabric, preventing wrinkles from affecting the comprehensiveness of the inspection.

[0029] The air blowing mechanism includes a fixed beam mounted on the frame, with multiple fans on the fixed beam; or the fixed beam has an air knife connected to the blower, with the air outlet of the air knife facing the fabric pressing mechanism, so that air is blown onto the fabric through the fans or the air knife connected to the blower. The structure is simple and has a good drying and smoothing effect on the fabric, laying the foundation for improving the flatness and smoothness of the fabric.

[0030] The frame is equipped with two light stands, which are located on both sides of the transparent inspection plate. Each light stand is equipped with a supplementary light, which illuminates the upper and lower sides of the transparent inspection plate to ensure sufficient brightness for the camera assembly to take pictures and improve the picture quality.

[0031] Since the light stand, transparent inspection plate, and camera assembly mounting pole are all equipped with adjustment plates at both ends, and the adjustment plates are mounted on the frame and have arc-shaped adjustment holes and mounting holes, and first connectors pass through the arc-shaped adjustment holes and mounting holes, the installation angles of the light stand, transparent inspection plate, and mounting pole can be adjusted through the arc-shaped adjustment grooves to ensure the compatibility of the supplementary light, transparent inspection plate, and camera assembly, which is beneficial to ensuring inspection accuracy.

[0032] Since the adjustment plates at both ends of the transparent inspection plate are set on the adjustment seat, and the adjustment seat is provided with vertical adjustment elongated holes and is installed on the frame, the installation height of the transparent inspection plate can be adjusted according to the diameter specification of the conveyor roller by the cooperation of the adjustment seat and the vertical adjustment elongated holes to meet the working requirements.

[0033] Since both ends of the fixed beam are equipped with adjustment brackets fixed to the support, and the adjustment brackets are equipped with arc-shaped waist holes, and a second connecting piece passing through the arc-shaped waist holes is provided between the adjustment brackets and the fixed beam, the installation angle of the fixed beam and the air guide or blower angle above it can be easily adjusted through the arc-shaped waist holes so that the blown air can achieve the best effect.

[0034] Because both ends of the support rod are equipped with rod seats; both ends of the bracket are equipped with frame seats; the linear power element is mounted on the mounting base and connected to the frame seat; the mounting base and rod seats are mounted on the frame, and the mounting base, rod seats, and the bracket and frame seat are all equipped with straightness adjustment mounting holes, so that the frame, support rod and linear power element can be matched through the transition of rod seats and mounting base. The straightness adjustment mounting holes facilitate the adjustment of the working position of support rod, bracket and linear power element to meet the working requirements of different specifications of conveyor rollers and support rods, and improve the versatility of use.

A discharge rack 103 is provided on the frame 1 downstream of the belt rollers 101, and a fabric pressing mechanism is provided on the frame 1 above the discharge rack 103. A transparent inspection plate 2 is provided on the frame 1 between the discharge rack 103 and the belt rollers 101.

[0047] The air blowing mechanism includes a fixed beam 6 mounted on the frame 1, on which multiple fans (fans are existing technology and therefore not shown in the figure) are mounted; or, on the fixed beam 6, an air knife 601 connected to a blower (not shown in the figure) is mounted, with the air outlet of the air knife 601 facing the fabric support mechanism (specifically, facing the support rod 501).

[0048] The frame 1 is equipped with two lamp holders 7, which are distributed on both sides of the transparent detection plate 2. Each lamp holder 7 is equipped with a supplementary light 701.

[0049] The lamp holder 7, the transparent detection plate 2, and the support pole 301 for mounting the camera assembly 3 are all equipped with adjustment plates 8 at both ends. The adjustment plates 8 are mounted on the frame 1 and are provided with arc-shaped adjustment holes 801 and mounting holes 802. A first connector (such as a connecting bolt) passes through both the arc-shaped adjustment hole 801 and the mounting hole 802. The first connector is connected to the frame 1.

[0050] Preferably, the adjusting plates 8 at both ends of the transparent detection plate 2 are mounted on the adjusting seat 201, which has a vertical adjusting elongated hole 202 and is mounted on the frame 1; both ends of the fixed beam 6 are provided with adjusting frames 602 fixed on the bracket 5, which have an arc-shaped waist hole 603, and a second connecting piece (such as a connecting bolt) passing through the arc-shaped waist hole 603 is provided between the adjusting frame 602 and the fixed beam 6.

[0051] In this embodiment, multiple camera components 3 located above the transparent detection plate 2 are positioned near the top of the frame 1. To ensure aesthetics, side plates 303 are provided on the frame 1 around the camera components 3. Meanwhile, to improve heat dissipation, multiple cooling fans 302 are provided on the top of the frame 1 above the camera components 3.
