[0024] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.
[0025] Example 1 like Figures 1-3 As shown, the present invention provides a detection mechanism for fluorescent impurities in woven bags, specifically including a mounting frame 1, a fixing frame 2, an electric conveying assembly 3, a detection box 4, a detection assembly 5, an ultraviolet reflector 6, and an ultraviolet lamp 7; The mounting frame 1 is provided with a fixing frame 2 on the top. The fixing frame 2 has a horizontal and hollow "I"-shaped tubular structure in the vertical direction, which is used to provide an environment with low external light influence for ultraviolet light irradiation detection. The fixed frame 2 is provided with electric conveying components 3 for clamping and conveying woven bags on both sides of the length direction. The electric conveying components 3 include two conveyor belts arranged symmetrically on the upper and lower sides. The surfaces of the two conveyor belts that contact the woven bags are provided with rubber protrusions. The two conveyor belts clamp the woven bags effectively without causing damage through the rubber protrusions. The fixed frame 2 is provided with a detection box 4 at the top. The detection box 4 is a triangular prism with a top sloping surface that slopes from high to low towards the woven bag outlet, and is used to provide an environment for ultraviolet lamp irradiation. The detection box 4 has multiple detection ports 401 evenly spaced on the side near the woven bag. The top of the inner side of the detection box 4 is provided with columnar recesses at the position directly opposite the detection ports 401. Each columnar recess is provided with a detection component 5 aligned with the detection port 401 for capturing and detecting fluorescence. The detection component 5 is located inside the columnar recess to prevent ultraviolet light from directly irradiating the lens and affecting the imaging results. The detection assembly 5 comprises a detection lens for image shooting and a central control assembly for processing the shooting information; the inside of the detection box 4 near the highest point of the top slope is provided with an ultraviolet lamp 7 opposite to the middle position of the inside of the detection box 4; The inside of the detection box 4 and the position away from the ultraviolet lamp 7 of each detection assembly 5 are provided with an ultraviolet reflector 6, which can refract the light of the ultraviolet lamp 7 to the adjacent detection port 401; The bottom of the fixed frame 2 and the position opposite to the bottom of the woven bag are provided with the same detection box 4, detection assembly 5, ultraviolet lamp 7 and reflector; the detection box 4 at the bottom of the fixed frame 2 is staggered with the detection port 401 of the detection box 4 at the top of the fixed frame 2; The number of detection lenses of the detection assembly 5 is multiple and is uniformly and interval arranged along the horizontal transverse direction of the detection box 4.
[0026] For example, in use, the ultraviolet lamp 7, detection component 5, and electric conveyor component 3 are activated sequentially. The woven bag is then conveyed by the electric conveyor component 3, passing sequentially through the detection ports 401 of the detection chamber 4. Since the detection chamber 4 is a triangular prism with a sloping top facing downwards towards the woven bag outlet, and the ultraviolet lamp 7 is positioned at the highest point of the sloping surface inside the detection chamber 4, the ultraviolet intensity at the detection ports 401 decreases as the distance from the ultraviolet lamp 7 increases. The triangular prism structure of the top slope of the detection chamber 4 further enhances this effect, achieving a gradient reduction in ultraviolet intensity across multiple detection ports 401. Finally, the ultraviolet reflector 6 ensures that ultraviolet light reaches each detection port 401 through reflection. The woven bag is conveyed from the highest to the lowest side of the sloping surface. Therefore, as the woven bag passes through the detection ports 401 sequentially, it undergoes multiple exposures to ultraviolet light of varying intensities. Simultaneously, the detection lens of the detection component 5 captures the fluorescence emission of the woven bag. Multiple lenses simultaneously photograph the woven bag at a single detection port 401 from different positions to improve the accuracy of the images. By comparing the fluorescence brightness and emission range emitted after absorbing ultraviolet light of the same intensity, the integrity of the fluorescent markings on the woven bag and the presence of other fluorescent impurities contaminating the bag surface can be determined. Furthermore, since different types of fluorescent substances exhibit different brightness changes under ultraviolet light of varying intensities, multiple exposures and tests at different intensities are conducted. By comparing the fluorescence emission effects, the influence of varying concentrations or uneven distribution of fluorescent substances on the test results can be avoided (e.g., the fluorescence emission effect at a concentrated distribution location is the same as that of fluorescent impurities), further ensuring the accuracy of the test results. In this embodiment, by setting identical detection structures above and below the fixed frame 2, both the upper and lower surfaces of the woven bag can be detected simultaneously. The staggered arrangement of the two detection chambers 4 according to the detection ports 401 prevents ultraviolet light from simultaneously irradiating the same upper and lower positions of the woven bag, thus avoiding fluorescence interference with the test results.
[0027] Example 2 like Figures 4-7 As shown, based on embodiment 1, it also includes a flattening assembly 8, which specifically includes a connecting frame 801, an electric push rod 802, a mounting base 803, an elastic element 804, a pressing roller 805, and a support platform 9. The detection box 4 is provided with a connecting frame 801 on the side close to the woven bag and close to the detection port 401, the connecting frame 801 is located on the side of the detection port 401 close to the woven bag entrance, the detection box 4 is provided with an electric push rod 802 opposite the connecting frame 801, the telescopic rod of the electric push rod 802 is connected with the connecting frame 801, the connecting frame 801 is provided with a mounting seat 803 on the side close to the woven bag in a sliding clamping mode, the mounting seat 803 is connected with the connecting frame 801 through an elastic element 804, and the mounting seat 803 is provided with an extrusion roller 805 on the side close to the woven bag in a rotating mode. The fixed frame 2 is provided with a support table 9 opposite each detection port 401 in the inside.
[0028] In the initial state, the electric push rod 802 is in the retracted state, the connecting frame 801, the mounting seat 803 and the extrusion roller 805 are driven away from the position of the woven bag, when the electric transmission assembly 3 drives the woven bag to move at the position of the detection port 401, the woven bag is shot by the detection assembly 5, and the external controller controls the electric push rod 802 to extend, so that the connecting frame 801 drives the extrusion roller 805 to extrude the woven bag, when the woven bag is pulled, the extrusion roller 805 can flatten the woven bag, and the elastic element 804 can keep a certain elastic movement distance between the mounting seat 803 and the connecting frame 801, so as to avoid that the extrusion roller 805 excessively extrudes the woven bag.
[0029] As shown in Figures 8-9 On the basis of example 1, a dust removal assembly 10 is further included, and the dust removal assembly 10 specifically includes a fixed seat 1001, a brush 1002 and a gear 1003. The mounting seat 803 closest to the woven bag entrance is provided with the fixed seat 1001, the fixed seat 1001 is arranged on the side of the mounting seat 803 close to the woven bag entrance, the fixed seat 1001 is provided with the brush 1002 in the inside in a rotating mode, the brush 1002 is farther away from the woven bag than the extrusion roller 805, and the brush 1002 contacts the woven bag. The extrusion roller 805 and the end of the brush 1002 are provided with the gears 1003 that are intermeshed.
[0030] When the extrusion roller 805 extrudes the woven bag, the brush 1002 arranged on the mounting seat 803 moves downward together and contacts the woven bag, when the extrusion roller 805 flattens the woven bag, the movement of the woven bag can make the extrusion roller 805 rotate, and the brush 1002 is driven by the intermeshed gears 1003 to rotate reversely relative to the extrusion roller 805, so as to clean the surface of the woven bag, thereby avoiding that the sundries or dust on the surface of the woven bag affects the fluorescent detection result.
[0031] As Figure 1 shown, the fixed frame 2 and the electric transmission assembly 3 are longer than the detection box 4, and the detection box 4 is located at the middle of the fixed frame 2.
[0032] By setting the transmission allowance of the electric transmission assembly 3 relative to the detection box 4, the transmission effect and state of the electric transmission assembly 3 on the woven bag can be easily observed, and the application can be easily connected to the production line of the woven bag.
[0033] Embodiment 3 The application also provides a detection method for fluorescent impurities of woven bags, which is applied to the above detection mechanism for fluorescent impurities of woven bags and includes the following steps. Step one: Place the woven bag at the woven bag entering end of the electric transmission assembly 3, and keep the woven bag facing the middle of the fixed frame 2. Step two: Start the ultraviolet lamp 7, the detection assembly 5 and the electric transmission assembly 3 in sequence, so that the woven bag passes through the detection ports 401 of the two detection boxes 4 in sequence, is irradiated by the ultraviolet light with the light intensity from strong to weak, and the fluorescent situation of the woven bag surface is captured by the lens of the detection assembly 5 and transmitted to the external controller for identification of whether it is qualified. Step three: The woven bag is transmitted out of the fixed frame 2 by the electric transmission assembly 3, and is classified according to the detection result.
