Description

Technical Field

[0001] This utility model relates to the field of fabric recognition, specifically to a fabric material detector based on hyperspectral imaging. Background Technology

[0002] Hyperspectral fabric material detectors are mainly used in the textile industry for fabric quality inspection and material identification. In the quality inspection stage after fabric production, material verification during the purchase of clothing fabrics, and material classification during the textile recycling process, these detectors use hyperspectral technology to analyze key information such as fabric composition, weaving method, and fiber type, providing data support for subsequent production processing, quality control, or resource reuse.

[0003] Existing hyperspectral imaging equipment for fabric inspection cannot effectively isolate the intrusion of external ambient light and internal stray light into the inspection area, making the fabric spectral data collected by the hyperspectral sensor susceptible to interference and affecting the accuracy of material identification. The equipment has poor clamping effect on fabrics of different widths, and the fabric is prone to displacement and shaking during movement and inspection, resulting in misalignment between the inspection area and the sensor. Although the equipment is equipped with auxiliary structures for fabric flattening, such as pressure rollers or smoothing scrapers, these structures cannot completely eliminate wrinkles on the fabric surface. Wrinkles will cause unevenness of the fabric surface in the inspection area, which in turn will distort the material information obtained by hyperspectral scanning. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings and provide a fabric material detector based on hyperspectral imaging. This solves the technical problem that existing structures cannot completely eliminate wrinkles on the fabric surface, which leads to unevenness on the fabric surface in the detection area and thus distorts the material information obtained by hyperspectral scanning.

[0005] The purpose of this utility model is achieved through the following means: A fabric material detector based on hyperspectral imaging includes a detection device base. A hyperspectral detection module is installed on one side of the top of the detection device base. A light shield is provided at the bottom of the hyperspectral detection module. An electric slide rail is provided on the top of the detection device base. A sliding platform is installed on the top of the electric slide rail via an electric slider. Limit blocks are provided at both ends of the sliding platform. A tensioning rod is movably inserted through the two ends of the limit blocks adjacent to the sliding platform. A clamping plate is connected to the end of the tensioning rod near the light shield. An anti-detachment block is provided at the other end of the tensioning rod located on the clamping plate. A return spring is provided between the anti-detachment block and the limit block. A flat platform is movably installed on one side of the sliding platform along the electric slide rail. A magnetic suction plate is movably provided on the top of the flat platform. Insert blocks are provided at both ends of the bottom of the magnetic suction plate. Slots corresponding to the insert blocks are opened at both ends of the flat platform. A limit rod is connected to one end of the sliding platform located on the flat platform. The limit rod passes through the flat platform. Preferably, a fan is installed on one outer wall of the base of the detection device, a first air intake is fixedly installed on one outer wall of the light shield located on the flat platform, and a second air intake is provided on the base of the detection device below the first air intake. Both the first air intake and the second air intake are connected to the air inlet of the fan.

[0006] The active suction function of the fan can drive the first and second suction ports to simultaneously adsorb dust, lint and other impurities on the fabric surface and around the detection area, preventing impurities from adhering to the fabric surface or entering the light shield and interfering with the detection signal of the hyperspectral detection module, ensuring accurate detection data. At the same time, it can keep the flat platform above the detection device base and the inside of the light shield clean, reducing the frequency of subsequent cleaning and maintenance of the equipment.

[0007] Preferably, a silicone anti-slip pad is attached to the side of the clamp closest to the fabric, and the surface of the silicone anti-slip pad is provided with uniformly distributed anti-slip texture.

[0008] Silicone anti-slip pads can increase the contact friction between the clamp and the fabric. Even if the electric slide rail causes slight vibration when moving the sliding platform, it can prevent the fabric from shifting on the sliding platform and ensure the relative position stability of the fabric and the hyperspectral detection module. Moreover, the soft silicone material will not cause indentations or scratches on the fabric surface, making it suitable for fixing thin and delicate fabrics.

[0009] Preferably, the flat platform is provided with a magnetic suction point that matches the magnetic suction plate, and the top surface of the magnetic suction plate is covered with an anti-slip buffer layer, which is detachably connected to the magnetic suction plate.

[0010] The magnetic attraction between the sizing platform and the magnetic plate allows for quick positioning and fixation of the magnetic plate without the need for additional fasteners, simplifying the fabric sizing process. The anti-slip buffer layer prevents the fabric from sliding during sizing and cushions the hard contact between the fabric and the magnetic plate, preventing fabric wear. The detachable design allows for replacement of the buffer layer according to the fabric characteristics and also makes it easy to clean or replace the buffer layer when it gets dirty, improving the adaptability of the sizing platform.

[0011] Preferably, both the first and second air inlets are equipped with detachable cleaning brushes at their openings.

[0012] The cleaning brush can lightly sweep the fabric surface near the opening when the first and second air inlets are drawing air, helping to remove small impurities with strong adhesion and enhancing the dust removal effect. The detachable design makes it easy to remove the brush for cleaning or replacement regularly, avoiding the accumulation of dirt on the brush and back-contamination of the detection area, and ensuring the continuous dust removal capability of the first and second air inlets.

[0013] Preferably, the fan is equipped with a dust filter at the connection between the first air inlet and the second air inlet.

[0014] The dust filter can intercept dust, fibers and other impurities that enter the fan, preventing impurities from wearing down the internal blades of the fan or clogging the channels, thus extending the service life of the fan; it is detachable and easy for users to remove the filter for regular cleaning or replacement.

[0015] The beneficial effects of this invention are as follows: The hyperspectral fabric material detector features a light-shielding cover that reduces light interference during detection. The limiting blocks at both ends of the sliding platform cooperate with the tightening rod, clamping plate, and return spring. The elasticity of the return spring allows the clamping plate to hold fabrics of different widths, preventing the fabric from shifting or swaying during movement and detection. The flattening platform on one side of the electric slide rail is paired with a magnetic suction plate. The magnetism of the magnetic suction plate flattens the fabric surface, eliminating the influence of wrinkles on detection and keeping the fabric flat in the detection area. This allows for more accurate acquisition of material information through hyperspectral detection. Furthermore, the magnetic suction plate, through its insert block, engages with the slot of the flattening platform to prevent shifting due to tension during movement. The limiting rod penetrates the flattening platform, restricting their relative positions and ensuring a stable relative relationship between the sliding platform and the flattening platform during movement. This prevents positional shifts that could cause problems with fabric transport or detection, ensuring the stability and reliability of the overall detection process. Attached Figure Description

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] In this embodiment, refer to Figure 1 - Figure 3The invention specifically implements a hyperspectral fabric material detector, comprising a detection device base 100, a hyperspectral detection module 101 mounted on one side of the top of the detection device base 100, a light shield 102 at the bottom of the hyperspectral detection module 101, an electric slide rail 103 at the top of the detection device base 100, a sliding platform 104 mounted on the top of the electric slide rail 103 via an electric slider, and limit blocks 105 at both ends of the sliding platform 104. A tensioning rod 106 is movably inserted through the two ends of the limit blocks 105 adjacent to the sliding platform 104. The end of the tensioning rod 106 near the light shield 102 is connected to... A clamping plate 108 is attached, and a tensioning rod 106 is located at the other end of the clamping plate 108 with an anti-detachment block 107. A reset spring is provided between the anti-detachment block 107 and the limiting block 105. An electric slide rail 103 is located on one side of the sliding platform 104 and a flat platform 109 is movably installed. A magnetic suction plate 110 is movably installed on the top of the flat platform 109. Insert blocks 111 are provided at both ends of the bottom of the magnetic suction plate 110. Slots 112 corresponding to the insert blocks 111 are opened at both ends of the flat platform 109. A limiting rod 113 is connected to one end of the sliding platform 104 located on the flat platform 109 and passes through the flat platform 109. A fan 200 is installed on one side of the outer wall of the detection device base 100. A first air intake 201 is fixedly installed on one side of the outer wall of the flat platform 109. A second air intake 202 is opened below the first air intake 201 on the detection device base 100. Both the first air intake 201 and the second air intake 202 are connected to the air intake end of the fan 200.

[0020] The active suction function of the fan 200 can drive the first suction port 201 and the second suction port 202 to simultaneously adsorb dust, lint and other impurities on the fabric surface and around the detection area, preventing impurities from adhering to the fabric surface or entering the light shield 102 and interfering with the detection signal of the hyperspectral detection module 101, ensuring accurate detection data, and keeping the flat platform 109 above the detection device base 100 and the inside of the light shield 102 clean, reducing the frequency of subsequent cleaning and maintenance of the equipment.

[0021] A silicone anti-slip pad is attached to the side of the clamp 108 closest to the fabric, and the surface of the silicone anti-slip pad has evenly distributed anti-slip texture.

[0022] The silicone anti-slip pad can increase the contact friction between the clamp 108 and the fabric. Even if the electric slide rail 103 causes slight vibration when it moves the sliding platform 104, it can prevent the fabric from shifting on the sliding platform 104 and ensure the relative position of the fabric and the hyperspectral detection module 101 is stable. Moreover, the soft silicone material will not cause indentations or scratches on the fabric surface, making it suitable for fixing thin and delicate fabrics.

[0023] The flat platform 109 is provided with a magnetic attachment point that matches the magnetic plate 110. The top surface of the magnetic plate 110 is covered with an anti-slip buffer layer, and the buffer layer is detachably connected to the magnetic plate 110.

[0024] The magnetic attraction between the flattening platform 109 and the magnetic plate 110 allows for quick positioning and fixation of the magnetic plate 110 without the need for additional fasteners, simplifying the fabric flattening process. The anti-slip buffer layer prevents the fabric from sliding during the flattening process and also cushions the hard contact between the fabric and the magnetic plate 110, preventing fabric wear. The detachable design allows for the replacement of the buffer layer according to the fabric characteristics and also facilitates cleaning or replacement of the buffer layer when it becomes dirty, improving the adaptability of the flattening platform 109.

[0025] Both the first air inlet 201 and the second air inlet 202 are equipped with detachable cleaning brushes at their openings.

[0026] The cleaning brush can lightly sweep the fabric surface near the opening when the first air inlet 201 and the second air inlet 202 are drawing air, helping to remove small impurities with strong adhesion and enhancing the dust removal effect. The detachable design makes it easy to remove the brush for cleaning or replacement regularly, avoiding the accumulation of dirt on the brush and contaminating the detection area, thus ensuring the continuous dust removal capability of the first air inlet 201 and the second air inlet 202.

[0027] Dust filters are detachably installed at the connection points of the first air intake 201 and the second air intake 202 of the fan 200.

[0028] The dust filter can intercept dust, fibers and other impurities that enter the fan 200, preventing impurities from wearing down the internal blades of the fan 200 or clogging the channels, thus extending the service life of the fan 200; the removable installation makes it convenient for users to regularly remove the filter for cleaning or replacement.

[0029] The working process of a hyperspectral-based fabric material detector in this embodiment is as follows: First, the fabric to be tested is placed on the sliding platform 104 and the flat platform 109 on the electric slide rail 103 at the top of the detection device base 100. The moving clamp 108 is pulled to clamp the fabric between the moving clamp 108 and the sliding platform 104. Under the elastic force of the return spring between the anti-detachment block 107 and the limiting block 105, the clamp 108 is pushed to achieve clamping and fixing of fabrics of different widths, preventing fabric displacement. The fabric is then placed on the flat platform 109. The flat platform 109 magnetically engages with the magnetic suction plate 110, combining the bottom insert 111 of the magnetic suction plate 110 with the slot 112 of the flat platform 109. Positioning: The flattening platform 109 is moved along the limiting rod 113 to the other side of the sliding platform 104 until it is close to the other end of the fabric. The fabric is flattened to eliminate wrinkles. Then, the electric slide rail 103 drives the sliding platform 104 and the fabric to move under the hyperspectral detection module 101. The bottom light shield 102 isolates external light and internal stray light to ensure a stable detection environment. When entering the light shield 102, the fan 200 on one side of the detection device base 100 is started, which drives the first air inlet 201 and the second air inlet 202 to adsorb impurities on the surface of the fabric and the detection area. The detachable cleaning brushes at the openings of both assist in cleaning. Finally, the hyperspectral detection module 101 accurately obtains the fabric material information.
