[0019] A detection method of an environmental protection new material paper pulp detection device, the detection method comprises:

[0020] After the paper pulp is subjected to the mixing, stirring, sedimentation, taking and drying steps by the sample paper forming module, sample paper same as the finished paper is obtained;

[0021] The sample paper is placed on the detection plate, and then the sample paper is fixed from four directions at the same time;

[0022] The light source is started, the light is emitted in a radial manner upward and uniformly acts on the surface of the sample paper;

[0023] The image information of the sample paper is collected from different angles by the upper groups of camera units, so that whether the shadow appears on the sample paper when the light passes through the sample paper is detected, so as to detect whether the impurities exist in the paper pulp, and the quality of the paper pulp is judged;

[0024] The two groups of hinged plates are deflected by the two groups of electric angular tables, so as to bend the sample paper, and the small hidden and deep impurities are made to leak out by the bending of the sample paper;

[0025] Contacting the fixation of sample paper, then driving the sample paper to rotate through the paper turning mechanism, so that the sample paper changes the bending orientation;

[0026] After all angles are bent, the detection work is completed.

[0027] The beneficial effects of the present application are:

[0028] 1. When detecting, not only can the sample paper be laid flat for light transmission detection, but also after the two sets of fixed clamping components and the two sets of fixing mechanisms are released, the two sets of hinged plates are driven to deflect by the two sets of electric angle tables, so that the paper is bent, thereby making the small hidden and deep impurities leak out by bending the sample paper, and after the fixation is released, the sample paper is driven to rotate by the paper turning mechanism, so that the function of bending the paper at any angle is realized, thereby detecting the sample paper without dead angle, and the detection accuracy is improved without manual moving of the sample paper.

[0029] 2. After contacting the fixation of the sample paper, the second motor, the center rotating plate and each set of side rotating plate are lowered by the fourth electric push rod until each set of anti-skid pad is attached to the sample paper, then the center rotating plate and each set of side rotating plate are driven to rotate by the second motor, and the sample paper is rotated by the friction force of the anti-skid pad. And when the sample paper rotates, the center rotating plate and each set of side rotating plate are forced at the same time, so that the sample paper is more evenly stressed, avoiding damage to the sample paper, not only protecting the sample paper, but also improving the smoothness of the detection work because the detection, rotation and bending are all controlled manually.

[0030] 3. The mixing cylinder for mixing, the frame mold cylinder for depositing paper pulp and the electric ball valve for drainage are designed as a split structure, when the water is drained, the mixing cylinder is first lifted by the first electric push rod to separate from the frame mold cylinder, then the frame mold cylinder is lifted by the second electric push rod to separate from the electric ball valve, and then the second extension rod is driven to rotate by the first motor, so that the frame mold cylinder can be smoothly connected to the sampling unit, thereby completing the transfer of the semi-finished sample paper. The whole process does not need manual operation and does not need to manually contact the semi-finished sample paper, avoiding damage to the semi-finished sample paper, and the first electric push rod and the second electric push rod also enhance the overall fixation effect, avoiding leakage of water and paper pulp. While improving the degree of automation, the quality of the semi-finished sample paper is also guaranteed.

[0031] 4. During detection, the sample paper can be fixed by extrusion of the upper and lower fixing members, and when the sample paper needs to be rotated, the upper fixing member is lifted by the electric sliding table to contact and fix the sample paper, and when the sample paper rotates, the friction force at the edge of the sample paper is also reduced by the groups of rollers arranged at equal intervals along the fan ring path, which better assists the paper turning work, thereby improving the functionality and auxiliary effect of the fixing mechanism.

[0032] 5. First, the downward pressure of the sampling hood allows the top of the semi-finished sample paper to adhere to the adhesive board. Then, high-pressure gas is sprayed vertically upward from below through several evenly distributed high-pressure air outlets, reducing the adhesion between the semi-finished sample paper and the sample board. Next, a servo cylinder drives the paper scraper to move horizontally into the sampling hood, passing between the sample board and the semi-finished sample paper, thus completely removing the semi-finished sample paper. Due to the pressure of the sampling hood in the early stage, the fiber distribution in the semi-finished sample paper is more uniform, and the paper surface is also correspondingly flat. Moreover, there is no need for employees to manually pick up the paper, thereby reducing labor intensity and shortening the sample paper manufacturing time.

[0033] 6. The end of the scraper block furthest from the servo cylinder is a pointed tip, which makes the scraper block form an inclined surface from top to bottom. The pointed tip can more easily scrape between the template and the semi-finished sample paper. Then, through the crescent groove and the inclined surface, the scraped semi-finished sample paper can be stably attached to the adhesive board, avoiding secondary slippage and preventing damage to the semi-finished sample paper due to uneven scraping force.

[0053] The side of sampling unit 400 away from transfer unit 300 is equipped with forming unit 500.

[0054] Forming unit 500 is used to dry moisture in semi-finished sample paper, so that the same sample paper as finished paper is obtained.

[0055] The illumination detection unit 600 is located on the side of forming table 100 close to forming unit 500.

High-temperature dehydration furnace 510 is equipped with heating component, and the heating component is preferably ceramic heating element.

[0057] After the semi-finished sample paper is taken out, it is placed in the high-temperature dehydration furnace 510, and then the sealing cover 520 is covered to form a sealed cavity. Then the air in the sealed cavity is pumped out through the vacuum valve 530 to form a vacuum cavity. Then the heating component is turned on to dry and heat the semi-finished sample paper until the moisture in the semi-finished sample paper is completely dried. The drying temperature is preferably 55-65°C.

[0058] As shown in Figure 3 and Figure 4 , the mixing unit 200 includes a water tank 210, the top of which is communicated with an electric ball valve 220, the top of which is movably mounted with a mold mounting mechanism 230, which is connected with the output end of the transfer unit 300. The mold mounting mechanism 230 is movably mounted with a mixing cylinder 240, which is provided with a first electric push rod 250 away from the transfer unit 300 side along the vertical direction. The output end of the first electric push rod 250 and the outer wall of the mixing cylinder 240 are connected with a first extension rod 251.

[0059] As shown in the drawings, , the transfer unit 300 includes a second electric push rod 310 arranged in the vertical direction, the top of which is provided with a first motor 320 in the vertical direction, the top of which is drivingly connected with a second extension rod 330, the other end of which is mounted on the mold mounting mechanism 230.

[0061] First, the pulp and water in the water tank 210 are injected into the mixing cylinder 240 according to the ratio of 1:5. Then stir in one direction until the pulp and water are completely mixed. Then the mixed liquid is placed. After the pulp is deposited, the electric ball valve 220 is opened, and the water in the mixing cylinder 240 is discharged into the water tank 210 through each group of micro-holes 233 for recycling. The pulp is completely adsorbed on the lofting plate 232 due to the deposition and interception of the lofting plate 232, thereby obtaining the semi-finished sample paper.

[0062] After the water is discharged, the first electric push rod 250 is opened, the mixing cylinder 240 is driven to rise and separate from the frame mold cylinder 231 by the first electric push rod 250, then the second electric push rod 310 is opened, the frame mold cylinder 231 and the semi-finished sample paper are driven to rise and separate from the electric ball valve 220 by the second electric push rod 310, and then the first motor 320 is started, the second extension rod 330 is driven to rotate by the first motor 320, so that the frame mold cylinder 231 is sleeved on the sampling unit 400.

[0063] By designing the mixing cylinder 240 for mixing, the frame mold cylinder 231 for precipitating pulp, and the electric ball valve 220 for draining as a split structure, when the water is discharged, the mixing cylinder 240 is first driven to rise and separate from the frame mold cylinder 231 by the first electric push rod 250, then the frame mold cylinder 231 is driven to rise and separate from the electric ball valve 220 by the second electric push rod 310, and then the second extension rod 330 is driven to rotate by the first motor 320, so that the frame mold cylinder 231 can be smoothly sleeved on the sampling unit 400, thereby completing the transfer of the semi-finished sample paper. The whole process does not need manual operation and does not need manual contact with the semi-finished sample paper, avoiding damage to the semi-finished sample paper by hand. The first electric push rod 250 and the second electric push rod 310 also enhance the overall fixing effect, avoiding leakage of water and pulp. While improving the degree of automation, the quality of the semi-finished sample paper is also guaranteed.

[0064] As shown in Figure 6 and Figure 7 , the sampling unit 400 includes a top plate 410, a third electric push rod 420 is installed at the bottom of the top plate 410 in the vertical direction, a sampling cover 430 is drivingly connected to the bottom of the third electric push rod 420, the bottom of the sampling cover 430 is an open structure, a paper sticking plate 431 is movably installed at the center of the top of the sampling cover 430, a through hole 432 is formed in one side wall of the sampling cover 430, and the height of the through hole 432 is the same as the height of the bottom of the paper sticking plate 431. A paper shoveling mechanism 440 is provided on the side away from the cavity of the sampling cover 430 in the horizontal direction, the output end of the paper shoveling mechanism 440 movably extends into the sampling cover 430 and is in sliding fit with the bottom of the paper sticking plate 431.

A high-pressure gas inlet 451 is provided on the side wall of the discharging table 450, and the input end of each group of high-pressure gas outlets 461 is in communication with the output end of the high-pressure gas inlet 451.

[0075] After the sample paper is made, it is placed on the detection plate 630, and then the two groups of electric sliding tables 651 are started to drive the two groups of upper fixing members to descend and cooperate with the two groups of lower fixing members to clamp the two ends of the sample paper, so as to fix the sample paper. Then the light source is started, and the light can be emitted radially upward after being refracted by the spherical glass cover 620, so as to uniformly act on the surface of the sample paper. Then the image information of the sample paper is collected from different angles by each group of camera units arranged in an annular array and inclined upward, so as to detect whether there are impurities in the paper pulp by whether there are shadows on the sample paper when the light transmits through the sample paper, and to judge the quality of the paper pulp.

[0076] When detecting, not only can the sample paper be laid flat for light transmission detection, but also after the two groups of fixed clamping components 633 and the two groups of fixing mechanisms 650 are released, the two groups of electric angle tables 640 are used to drive the two groups of hinged plates 632 to deflect, so as to bend the paper, so that the small hidden and deep impurities are leaked out by bending the sample paper, and after being contacted and fixed, the sample paper is rotated by controlling the paper turning mechanism 660, so as to realize the function of bending the paper at any angle, so as to detect the sample paper without dead angle, and improve the detection accuracy without manual moving the sample paper.

[0077] After the sample paper is fixed, the fourth electric push rod 661 drives the second motor 662, the center rotating plate 663 and each group of side rotating plates 665 to descend until each group of anti-skid pads 666 are attached to the sample paper, and then the second motor 662 drives the center rotating plate 663 and each group of side rotating plates 665 to rotate, and the sample paper is rotated by the friction of the anti-skid pads 666. When the sample paper rotates, the center rotating plate 663 and each group of side rotating plates 665 are forced at the same time, so that the sample paper is more evenly stressed, avoiding damage to the sample paper, which not only protects the sample paper, but also improves the smoothness of the detection work because the detection, rotation and bending are all controlled manually.

[0078] In the detection, through the extrusion of the upper fixing part and the lower fixing part, the sample paper can be fixed, and when the sample paper needs to be rotated, only the upper fixing part is driven to ascend by the electric sliding table 651 to contact and fix the sample paper, and when the sample paper rotates, the friction at the edge of the sample paper is also reduced through the groups of roller wheels 655 arranged at equal intervals along the fan ring-shaped path, so that the rotation of the paper is better assisted, and the functionality and auxiliary effect of the fixing mechanism 650 are improved.

[0086] The third electric push rod is started, and the sampling cover is driven to descend by the third electric push rod until the paper sticking plate is in contact with the sample paper;

[0087] The high-pressure gas outside is connected to the high-pressure gas inlet, and then the high-pressure gas acts on the sample paper through the groups of high-pressure gas outlets and micro-holes, so that the sample paper can be loosened from the sample plate;

[0093] The two sets of hinged plates are deflected by the two sets of electric angle tables, so as to bend the sample paper, so as to make the small hidden and deep impurities leak out by bending the sample paper;

[0094] After the sample paper is fixed, the second motor, the center rotating plate and the groups of side rotating plates are driven downward by the fourth electric push rod until the groups of anti-skid pads are attached to the sample paper;

[0095] The center rotating plate and the groups of side rotating plates are rotated by starting the second motor, and the sample paper is rotated by the friction force of the anti-skid pads, so that the bending direction of the sample paper is changed;

[0096] After all the angles are bent, the detection work is completed.
