Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically to a sanitary product impurity analyzer. Background Technology

[0002] The aforementioned hygiene products specifically refer to disposable products used to absorb human excrement (such as urine and menstrual blood), mainly including baby diapers, adult incontinence pads, sanitary napkins, and panty liners. These products are typically made from non-woven fabrics, fluff pulp, superabsorbent polymers, PE films, and other materials through multiple processing steps. Their core function is to quickly absorb and lock in liquids, keeping the user's skin dry and comfortable.

[0003] Since sanitary products come into direct contact with the most sensitive and delicate parts of the human body, quality and safety control during the production process is crucial. High-speed machinery on the production line, foreign objects that may be mixed into the raw materials (such as metal shavings, plastic fragments, rubber particles, insect eggs, etc.), or impurities generated due to equipment aging can all become embedded inside the product. Therefore, testing each sanitary product for impurities before it leaves the factory is an indispensable and critical quality control step to protect consumer rights and maintain the manufacturer's brand image.

[0004] Currently, a widely used offline detection method in the industry is the transmitted light observation method. This method relies on a dedicated impurity analyzer. Its basic working principle is as follows: the device has a light source plate (usually made of milky white glass or acrylic) with a built-in uniform light source. During testing, the operator lays the hygiene product to be tested (such as diapers or sanitary napkins) flat on the light source plate, then turns on the light source. The light is transmitted upwards from below the plate, passing through the various layers of the hygiene product. When the light encounters impurities of different densities and materials, it will create obvious shadows or light spot differences at the corresponding locations. The inspector can then visually identify these abnormal shadows on the product surface, thus determining the presence and approximate location of the impurities.

[0005] In order to keep the sample flat and stable during observation and prevent it from slipping or wrinkling and affecting the observation, traditional measuring instruments usually have hook-and-loop fasteners attached to the left and right ends of the light source plate. After the sample is laid out, the operator needs to press the edge areas on both sides of the sample onto the hook-and-loop fasteners to fix it in place.

[0006] Although traditional measuring instruments can fix the sample to both sides using the barbs of the Velcro at both ends, due to the huge size differences between different types of hygiene products, the Velcro barbs are permanently and fixedly installed at both ends of the panel. For shorter samples, the edges cannot extend to the Velcro area on both sides, resulting in ineffective sample fixation and poor adaptability. Utility Model Content

[0007] The purpose of this invention is to provide a sanitary product impurity analyzer in response to the defects and deficiencies of the existing technology.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a hygiene product impurity analyzer, comprising an analyzer body, a light source plate disposed on the analyzer body, two fixed seats symmetrically disposed on the upper end face of the analyzer body, two fixed pressure plates hinged at one end to the fixed seats for pressing the sample onto the light source plate when the sample is laid on the light source plate, and an adjustment device disposed between the two fixed seats and the analyzer body for adjusting the two fixed seats to move closer or further apart, thereby driving the two fixed pressure plates to move and adjust.

[0009] A further improvement is that the adjustment device includes two fixed columns fixedly mounted on the instrument body and symmetrically arranged, and sliding openings that are respectively opened through the two fixed seats and are in clearance fit with the fixed columns.

[0010] Further effect: When it is necessary to adjust the distance between the fixed seats, the two fixed seats are moved by the cooperation of the fixed column in the sliding opening, so that the fixed seats can move closer to each other or further apart.

[0011] A further improvement is that the fixed column is a square column, and the sliding opening is a rectangular opening.

[0012] Further benefits: The design of the square column and rectangular opening allows the fixed base to be moved and adjusted while restricting its rotation on the measuring instrument body.

[0013] A further improvement is that the other end of the two fixed pressure plates is provided with a pressing element for pressing the sample firmly when the fixed pressure plate presses the sample onto the light source plate.

[0014] A further improvement is that the pressing component includes a counterweight block disposed at the other end of the fixed pressure plate.

[0015] Further effect: When the fixed pressure plate rotates around the fixed seat to press the sample onto the light source plate, the counterweight block drives the fixed pressure plate to maintain the pressure on the sample, thereby pressing the sample tightly onto the light source plate.

[0016] A further improvement is that the pressing component includes an extension plate disposed at the other end of the fixed pressure plate, a magnetic absorbing sheet disposed on the side end face of the measuring instrument body and located at the end of the extension plate, and an absorbing sheet disposed on the extension plate and near the end of the magnetic absorbing sheet for magnetic attraction with the magnetic absorbing sheet, wherein the magnetic absorbing sheet is disposed along the length direction of the measuring instrument body.

[0017] Further effect: When the fixed plate rotates around the fixed seat to press the sample onto the light source plate, the suction plate of the extension plate is close to the magnetic suction plate. The magnetic suction plate and the suction plate generate magnetic attraction, which makes the fixed plate press the sample tightly onto the light source plate, preventing the fixed plate from loosening and causing the sample to slide or wrinkle.

[0018] A further improvement is that the magnetic attracting sheet is an south pole magnetic sheet, and the attraction sheet is a north pole magnetic sheet.

[0019] A further improvement is that the suction sheet is made of metallic iron, metallic cobalt, or metallic nickel.

[0020] A further improvement is that the weight of the fixing base is 500-3000 grams.

[0021] Further benefits: When the fixing seat loses external force, it presses against the instrument body by its own weight, thereby fixing the positions of the two fixing plates, which facilitates the subsequent fixing of the same sample.

[0022] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When the sample is laid on the light source plate for impurity detection, the two fixed seats are moved by pushing them through the cooperation of the fixed column in the sliding opening according to the length of the sample. The two fixed seats are adjusted to move closer or further apart to drive the two fixed pressure plates to move and adjust until the fixed pressure plates are located at the left and right ends of the sample. Then, the two fixed pressure plates are pulled and rotated around the fixed seats so that the two fixed pressure plates press on the left and right ends of the sample respectively, thereby pressing the sample flat on the light source plate for fixation, preventing the sample from sliding or wrinkling and affecting observation. The distance between the two fixed pressure plates can be adjusted according to the measured sample length, thereby effectively fixing the sample and having high adaptability.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0027] See Figures 1 to 4 As shown, the technical solution adopted in this specific embodiment is: a hygiene product impurity analyzer, including an analyzer body 1, a light source plate 2 disposed on the analyzer body 1, two fixed seats 3 symmetrically disposed on the upper end face of the analyzer body 1, two fixed pressure plates 4 hinged at one end to the fixed seats 3 for pressing the sample onto the light source plate 2 when the sample is laid on the light source plate 2, and an adjustment device disposed between the two fixed seats 3 and the analyzer body 1 for adjusting the two fixed seats 3 to move closer or further apart, thereby driving the two fixed pressure plates 4 to move and adjust. Figure 3 As shown, hinge rods are provided at the other end of the fixed pressure plate 4 and the side end face of the fixed base 3. The two hinge rods are provided with hinge holes and are connected by a pin. The light source plate 2 is tilted on the measuring instrument body 1, and the fixed pressure plate 4 has the same tilt angle as the light source plate 2.

[0028] The adjustment device includes two fixed posts 5 symmetrically arranged and fixedly mounted on the instrument body 1, and sliding openings 6 respectively through the two fixed seats 3 and fitted with the fixed posts 5 with clearance. The fixed posts 5 are fixedly mounted on the instrument body 1 by threads, welding or bonding.

[0029] The fixed post 5 is a square post, and the sliding opening 6 is a rectangular opening. For example... Figure 2 As shown, the square column of the fixed post 5 and the rectangular opening of the sliding opening 6 are fitted with a clearance, allowing the fixed seats 3 to move closer or further apart at the upper end of the measuring instrument through the fixed post 5 positioned within the sliding opening 6. The fixed post 5 can also be a circular column, and the sliding opening 6 can be an oblong opening, both extending along the length of the fixed seat 3. Setting the fixed post 5 as a square column and the sliding opening 6 as a rectangular opening prevents the fixed seat 3 from rotating on the measuring instrument body 1, allowing the fixed seat 3 to maintain movement in one direction.

[0030] The other end of the two fixed pressure plates 4 is provided with a pressing element for pressing the sample when the fixed pressure plate 4 presses the sample onto the light source plate 2.

[0031] The pressing component includes a counterweight (not shown in the figure, the counterweight is located on the extension plate 7, i.e., the extension plate 7 is the counterweight) disposed at the other end of the fixed pressure plate 4. The weight of the counterweight (not shown in the figure) is between 500 and 3000 grams.

[0032] The pressing component includes an extension plate 7 disposed at the other end of the fixed pressure plate 4, a magnetic absorbing piece 8 disposed on the side end face of the measuring instrument body 1 and located at the end of the extension plate 7, and an absorbing piece 9 disposed on the extension plate 7 and near the end of the magnetic absorbing piece 8 for magnetic attraction with the magnetic absorbing piece 8. The magnetic absorbing piece 8 is disposed along the length direction of the measuring instrument body 1.

[0033] The magnetic attracting piece 8 is an south pole magnetic piece, and the attracting piece 9 is a north pole magnetic piece.

[0034] The suction sheet 9 is made of metal iron, metal cobalt, or metal nickel.

[0035] The weight of the fixing base 3 is 500-3000 grams.

[0036] The working principle of this utility model is as follows: When the sample is laid on the light source plate 2 to detect impurities, the two fixed seats 3 are moved according to the length of the sample by pushing them through the cooperation of the fixed column 5 in the sliding opening 6. The two fixed seats 3 are adjusted to move closer or further apart to drive the two fixed pressure plates 4 to move and adjust until the fixed pressure plates 4 are located at the left and right ends of the sample. Then, the two fixed pressure plates 4 are pulled to rotate around the fixed seats 3 so that the two fixed pressure plates 4 press on the left and right ends of the sample respectively. When the fixed pressure plates 4 rotate around the fixed seats 3 to press the sample on the light source plate 2, the suction plate 9 of the extension plate 7 is close to the magnetic suction plate 8. The magnetic suction plate 8 and the suction plate 9 generate magnetic adsorption, so that the fixed pressure plates 4 press the sample tightly on the light source plate 2, preventing the fixed pressure plates 4 from loosening and causing the sample to slide or wrinkle. The distance between the two fixed pressure plates 4 can be adjusted according to the measured sample length, so as to effectively fix the sample and has high adaptability. When the fixed base 3 loses external force, the fixed base 3 presses itself against the measuring instrument body 1 by its own weight, thereby fixing the positions of the two fixed pressure plates 4, which makes it easier to fix the same sample in the future.
