[0013] Furthermore, a paper scraping mechanism is provided in the horizontal direction on one side of the through hole away from the sampling cover cavity, and the output end of the paper scraping mechanism movably extends into the sampling cover and slidably fits with the bottom of the adhesive paper board.

[0014] A detection method for an environmentally friendly new material pulp detection device, the detection method comprising: After the pulp is mixed, stirred, settled, taken and dried by the sample paper forming module, a sample paper identical to the finished paper is obtained; Place the sample paper on the test board, and then fix the sample paper from four directions at the same time; Start the light source so that the light is emitted radially upward and evenly acts on the surface of the sample paper; The image information of the sample paper is collected from different angles by the camera units above. When light passes through the sample paper, whether there is a shadow on the sample paper is detected, so as to detect whether there are impurities in the pulp and judge the quality of the pulp; Two sets of electric angle tables drive two sets of hinged plates to deflect, so as to bend the paper, so that small and hidden deep impurities can be leaked out by bending the sample paper; The contact fixes the sample paper, and then drives the sample paper to rotate through the paper transfer mechanism, so that the sample paper changes its bending direction; After all angles are bent, the inspection is completed.

[0015] The beneficial effects of the present invention are as follows: 1. During the detection, not only can the sample paper be laid flat for light transmission detection, but also after releasing the fixation of the two groups of fixed clamping components and the two groups of fixing mechanisms, the two groups of electric angular position tables can be driven to deflect the two groups of hinged plates, thereby bending the paper, so that small, hidden and deep impurities can leak out by bending the sample paper. And after releasing the fixation, by controlling the paper rotating mechanism to drive the sample paper to rotate, the function of bending the paper at any angle can be realized, so as to detect the sample paper without dead angles. Without manually moving the sample paper, the detection accuracy is also improved.

[0016] 2. After releasing the fixation of the sample paper, the fourth electric push rod drives the second motor, the central rotating plate and each group of side rotating plates to descend until each group of anti-slip pads are all attached to the sample paper. Then the second motor is started to drive the central rotating plate and each group of side rotating plates to rotate, and the friction force of the anti-slip pads is used to make the sample paper rotate. And when the sample paper rotates, the central rotating plate and each group of side rotating plates distributed in an annular array exert force at the same time, so that the force on the sample paper is more uniform, avoiding damage to the sample paper, protecting the sample paper, and also improving the fluency of the detection work because the whole process of detection, rotation and bending does not require manual control.

[0017] 3. By designing the mixing cylinder for mixing, the formwork cylinder for precipitating pulp and the electric ball valve for draining water as a split structure, after the clear water is drained, first the first electric push rod drives the mixing cylinder to rise and separate from the formwork cylinder, then the second electric push rod rises to drive the formwork cylinder to separate from the electric ball valve, and then the first motor drives the second extension rod to rotate, so that the formwork cylinder can be smoothly sleeved on the sampling unit, thus completing the transfer of the semi-finished sample paper. The whole process does not require manual operation or manual contact with the semi-finished sample paper, avoiding damage to the semi-finished sample paper by hand, and also strengthening the overall fixing effect through the first electric push rod and the second electric push rod to avoid leakage of clear water and pulp. While improving the degree of automation, the quality of the semi-finished sample paper is also guaranteed.

[0018] 4. During the detection, the sample paper can be fixed by the extrusion of the upper fixing part and the lower fixing part. When the sample paper needs to be rotated, only the electric sliding table is used to drive the upper fixing part to rise to release the fixation of the sample paper. And when the sample paper rotates, the friction force at the edge of the sample paper is also reduced by each group of rollers arranged at equal intervals along the fan-shaped path, which better assists the paper rotating work, thereby improving the functionality and auxiliary effect of the fixing mechanism.

[0019] 5. First, the top of the semi-finished sample paper is adsorbed onto the cardboard by the downward extrusion of the sampling hood. Then, high-pressure gas is vertically ejected upward from below through several groups of evenly distributed high-pressure air outlets to reduce the adsorption force between the semi-finished sample paper and the sample placing board. Next, the servo electric cylinder drives the paper shoveling block to translate into the sampling hood and pass through between the sample placing board and the semi-finished sample paper, thereby completely removing the semi-finished sample paper. Due to the previous extrusion of the sampling hood, the fiber distribution in the semi-finished sample paper becomes more uniform, and the paper surface can also be correspondingly flattened. Moreover, there is no need for employees to manually pick up the paper, thus reducing the labor intensity and shortening the time for manufacturing the sample paper.

[0020] 6. One end of the paper shoveling block away from the servo electric cylinder is a tip, which makes the upper and lower parts of the paper shoveling block form an inclined plane. And the tip can more easily shovel into the space between the sample placing board and the semi-finished sample paper. Then, through the crescent groove and the inclined plane, the lifted semi-finished sample paper can be smoothly attached to the cardboard, avoiding secondary slippage and also preventing damage to the semi-finished sample paper due to uneven paper shoveling force.

[0021] Other features and advantages of the present invention will be described in the following specification.

Detailed implementation manners

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0037] An embodiment of the present invention provides an environmental protection new material pulp detection device. Exemplarily, as Figure 1 shown, it includes a sample paper forming module and a light detection unit 600. The sample paper forming module includes a forming table 100. A mixing unit 200 is provided on the top of the forming table 100, and a transfer unit 300 is provided on one side of the mixing unit 200. The sample paper forming module is used to make pulp into the sample paper required for detection, and the light detection unit 600 is used to observe impurities in the sample paper through light.

[0038] A sampling unit 400 is provided on the side of the transfer unit 300 away from the mixing unit 200, and the output end of the transfer unit 300 extends movably to the mixing unit 200 and the sampling unit 400.

[0039] The mixing unit 200 is used to mix pulp and clear water and precipitate them into semi-finished sample paper. The transfer unit 300 is used to move the semi-finished sample paper onto the sampling unit 400, and the sampling unit 400 is used to remove the semi-finished sample paper.

[0040] A forming unit 500 is provided on the side of the sampling unit 400 away from the transfer unit 300.

[0041] The forming unit 500 is used to dry the moisture in the semi-finished sample paper to obtain a sample paper identical to the finished paper.

[0042] The light detection unit 600 is located on the side of the forming table 100 close to the forming unit 500.

[0043] Exemplarily, as Figure 2 shown, the forming unit 500 includes a high-temperature dehydration furnace 510. A sealing cover 520 is movably installed on the top of the high-temperature dehydration furnace 510, and a vacuum valve 530 is connected to the high-temperature dehydration furnace 510. A heating component is provided in the high-temperature dehydration furnace 510, and the heating component is preferably a ceramic heating element.

[0044] After removing the semi-finished sample paper, place it in the high-temperature dehydration furnace 510, then cover it with the sealing cover 520 to form a sealed cavity. Then, evacuate the air in the sealed cavity through the vacuum valve 530 to form a vacuum cavity. Then, turn on the heating component to dry and heat the semi-finished sample paper until the moisture in the semi-finished sample paper is completely dried. Among them, the drying temperature is preferably 55-65 °C.

[0045] Exemplarily, such as Figure 3 and Figure 4 As shown, the mixing unit 200 includes a water tank 210. A motorized ball valve 220 is connected to the top of the water tank 210. A mold rack mechanism 230 is movably installed on the top of the motorized ball valve 220. The mold rack mechanism 230 is connected to the output end of the transfer unit 300. A mixing cylinder 240 is movably installed on the top of the mold rack mechanism 230. A first electric push rod 250 is provided along the vertical direction on the side of the mixing cylinder 240 away from the transfer unit 300. A first extension rod 251 is connected between the output end of the first electric push rod 250 and the outer wall of the mixing cylinder 240.

[0046] Exemplarily, the transfer unit 300 includes a second electric push rod 310 arranged along the vertical direction. A first motor 320 is provided along the vertical direction on the top of the second electric push rod 310. A second extension rod 330 is drivingly connected to the top of the first motor 320. The other end of the second extension rod 330 is installed on the mold rack mechanism 230.

[0047] Exemplarily, such as Figure 5 As shown, the mold rack mechanism 230 includes a mold rack cylinder 231 with open structures at both the upper and lower ends. A sample placing plate 232 is installed at the opening of the top of the mold rack cylinder 231. A number of groups of micropores 233 are evenly distributed on the sample placing plate 232.

[0048] First, inject the pulp and the clear water in the water tank 210 into the mixing cylinder 240 at a ratio of 1:5. Then stir in one direction until the pulp and the clear water are completely mixed. Then let the mixed liquid stand. After standing and waiting for the pulp to precipitate, turn on the motorized ball valve 220 to discharge the clear water in the mixing cylinder 240 through each group of micropores 233 into the water tank 210 for recycling. And the pulp is all adsorbed on the sample placing plate 232 due to precipitation and the interception of the sample placing plate 232, thereby obtaining the semi-finished sample paper.

[0049] After the clear water discharge is completed, the first electric push rod 250 is activated to drive the mixing cylinder 240 to rise and separate from the mold rack cylinder 231 through the first electric push rod 250. Then, the second electric push rod 310 is activated to drive the mold rack cylinder 231 and the semi-finished sample paper to rise and separate from the electric ball valve 220 through the second electric push rod 310. Next, the first motor 320 is started to drive the second extension rod 330 to rotate through the first motor 320, so that the mold rack cylinder 231 is sleeved on the sampling unit 400.

[0050] By designing the mixing cylinder 240 for mixing, the mold rack cylinder 231 for pulp precipitation, and the electric ball valve 220 for drainage as a split structure, after the clear water is drained, first drive the mixing cylinder 240 to rise and separate from the mold rack cylinder 231 through the first electric push rod 250, then drive the mold rack cylinder 231 to separate from the electric ball valve 220 through the second electric push rod 310 rising, and then drive the second extension rod 330 to rotate through the first motor 320, so that the mold rack cylinder 231 can be smoothly sleeved on the sampling unit 400, thus completing the transfer of the semi-finished sample paper. The whole process does not require manual operation, nor manual contact with the semi-finished sample paper, avoiding damage to the semi-finished sample paper by hand, and also strengthening the overall fixing effect through the first electric push rod 250 and the second electric push rod 310, avoiding leakage of clear water and pulp. While improving the degree of automation, it also ensures the quality of the semi-finished sample paper.

[0051] Exemplarily, such as Figure 6 and Figure 7 As shown, the sampling unit 400 includes a top plate 410. A third electric push rod 420 is installed vertically at the bottom of the top plate 410. 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 sticky paper board 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. The height of the through hole 432 is the same as the height of the bottom of the sticky paper board 431. A paper shoveling mechanism 440 is provided horizontally on the side of the through hole 432 away from the cavity of the sampling cover 430. The output end of the paper shoveling mechanism 440 extends movably into the sampling cover 430 and is slidably attached to the bottom of the sticky paper board 431.

[0052] Exemplarily, a feeding table 450 is coaxially arranged directly below the sampling cover 430. A clamping platform 460 is provided on the top of the feeding table 450. The bottom of the mold rack cylinder 231 is movably sleeved on the clamping platform 460. A number of groups of high-pressure air outlets 461 are evenly distributed on the top of the clamping platform 460. A high-pressure air inlet 451 is provided on the side wall of the feeding table 450. The input end of each group of high-pressure air outlets 461 is communicated with the output end of the high-pressure air inlet 451.

[0053] Exemplarily, such as Figure 8As shown, the paper shoveling mechanism 440 includes a servo electric cylinder 441 arranged in the horizontal direction. A paper shoveling block 442 is installed on the output end of the servo electric cylinder 441. A tip 443 is provided at one end of the paper shoveling block 442 away from the servo electric cylinder 441. Two groups of crescent grooves 444 are symmetrically arranged on both sides of the tip 443. The paper shoveling block 442 extends into the sampling cover 430 movably and is in sliding fit with the bottom of the cardboard 431.

[0054] By the operation of the first motor 320, the second extension rod 330 rotates, and drives the die mounting cylinder 231 to be sleeved on the clamping table 460. Then the third electric push rod 420 is started, and the sampling cover 430 is driven by the third electric push rod 420 to descend until the cardboard 431 abuts against the semi-finished sample paper. At the same time, external high-pressure gas is connected to the high-pressure air inlet 451. The high-pressure gas then acts on the semi-finished sample paper through each group of high-pressure air outlets 461 and the micropores 233, so that the semi-finished sample paper can be separated from the sample placing plate 232. And due to the descent and abutment of the sampling cover 430, the semi-finished sample paper can be adsorbed on the cardboard 431. Then the servo electric cylinder 441 is started, and the paper shoveling block 442 is pushed into the sampling cover 430 by the servo electric cylinder 441. Then it passes through between the semi-finished sample paper and the sample placing plate 232 through the tip 443, and further shovels the semi-finished sample paper out of the sample placing plate 232. Then the sampling cover 430 is controlled to rise, and the cardboard 431 is placed in the forming unit 500 for baking until the moisture in the semi-finished sample paper is completely evaporated, thereby obtaining the finished sample paper.

[0055] First, due to the descent and extrusion of the sampling cover 430, the top of the semi-finished sample paper can be adsorbed on the cardboard 431. Then, a plurality of groups of high-pressure air outlets 461 evenly distributed spray high-pressure gas vertically upward from below to reduce the adsorption force between the semi-finished sample paper and the sample placing plate 232. Then the paper shoveling block 442 is driven by the servo electric cylinder 441 to translate into the sampling cover 430 and pass through between the sample placing plate 232 and the semi-finished sample paper, so as to completely remove the semi-finished sample paper. And due to the previous extrusion of the sampling cover 430, the fiber distribution in the semi-finished sample paper is more uniform, the paper surface can also be correspondingly flat, and there is no need for employees to manually take the paper, thereby reducing the labor intensity and shortening the time for manufacturing the sample paper.

[0056] One end of the paper shoveling block 442 away from the servo electric cylinder 441 is the tip 443, which makes the upper and lower surfaces of the paper shoveling block 442 form inclined planes. And the tip 443 can more easily shovel into the space between the sample placing plate 232 and the semi-finished sample paper. Then through the crescent grooves 444 and the inclined planes, the shoveled semi-finished sample paper can be stably attached to the cardboard 431, avoiding secondary slipping and also avoiding damaging the semi-finished sample paper due to uneven paper shoveling force.

[0057] Exemplarily, such as Figure 9 and Figure 10As shown, the light detection unit 600 includes a detection box 610. At the center of the bottom of the cavity of the detection box 610, there is a spherical glass cover 620, and a light source is provided inside the spherical glass cover 620. A detection plate 630 is provided directly above the spherical glass cover 620. The detection plate 630 is made of transparent glass and includes a fixed plate 631 and two sets of hinged plates 632 hinged on both sides thereof. The fixed plate 631 and the two sets of hinged plates 632 are combined to form a disc-shaped structure. At the top edges of the ends of the two sets of hinged plates 632 away from each other, there are respectively a set of fixed clamping components 633, and the fixed clamping components 633 are preferably electric clamping plates. At the edge of each set of hinged plates 632, a set of cross bars 641 are installed in the horizontal direction, and the other end of the cross bar 641 is drivingly connected to an electric angular position table 640. The brand model of the electric angular position table 640 is EADA20. On both sides of the fixed plate 631 perpendicular to the hinged plates 632, two sets of fixing mechanisms 650 are symmetrically provided. A paper rotating mechanism 660 is coaxially provided directly above the detection plate 630, and the bottom of the paper rotating mechanism 660 is movably attached to the detection plate 630. Around the paper rotating mechanism 660, a number of camera units for collecting sample paper image information are obliquely arranged in a circular array.

[0058] Exemplarily, as Figure 11 shown, the fixing mechanism 650 includes an electric sliding table 651 arranged in the vertical direction. An upper fixing part is installed on the output end of the electric sliding table 651. A lower fixing part is provided directly below the upper fixing part. The upper fixing part and the lower fixing part have the same structure and are symmetrically arranged with each other. The top height of the lower fixing part is the same as the top height of the detection plate 630.

[0059] Exemplarily, the lower fixing part includes a crescent plate 652 with a fan-shaped cross-section in a top view. A crescent groove 653 with the same cross-section as that in the top view is provided at the top of the crescent plate 652. A number of rotating rods 654 are arranged at equal intervals along the length direction of the crescent groove 653. A roller 655 is rotatably sleeved on each rotating rod 654.

[0060] Specifically, each roller 655 of the lower fixing part is movably attached to each roller 655 of the upper fixing part.

[0061] Exemplarily, as Figure 12As shown, the paper transfer mechanism 660 includes a fourth electric push rod 661 arranged in the vertical direction. The bottom of the fourth electric push rod 661 is drivingly connected to a second motor 662. The bottom of the second motor 662 is drivingly connected to a central rotating plate 663. A number of groups of third extension rods 664 are distributed in a circular array at the peripheral edge of the central rotating plate 663. The other end of each group of third extension rods 664 is provided with a side rotating plate 665. The bottom height of the side rotating plate 665 is the same as the bottom height of the central rotating plate 663. A group of anti-slip pads 666 are provided at the bottom of the central rotating plate 663 and the bottom of each group of side rotating plates 665.

[0062] After the sample paper is made, it is placed on the detection plate 630. Then, two electric sliding tables 651 are started, so as to drive the two upper fixing parts to descend simultaneously, and cooperate with the two lower fixing parts to clamp both ends of the sample paper, thereby fixing the sample paper. Then, the light source is started. After the light is refracted by the spherical glass cover 620, it can be emitted radially upward, so that it can act evenly on the surface of the sample paper. Then, the image information of the sample paper is collected from different angles by the upper groups of camera units arranged in a circular array and inclined, so that when the light passes through the sample paper, whether there is a shadow on the sample paper is used to detect whether there are impurities in the pulp, thereby judging the quality of the pulp.

[0063] During the detection, not only can the sample paper be laid flat for light transmission detection, but also after releasing the fixation of the two fixed clamping parts 633 and the two fixing mechanisms 650, the two electric angular position platforms 640 are used to drive the two hinge plates 632 to deflect, so as to bend the paper, so that small, hidden and deep impurities can be leaked out by bending the sample paper. And after releasing the fixation, by controlling the paper transfer mechanism 660 to drive the sample paper to rotate, the function of bending the paper at any angle can be realized, so as to perform a non-blind spot detection on the sample paper. Without manually moving the sample paper, the detection accuracy is also improved.

[0064] After releasing the fixation of the sample paper, the fourth electric push rod 661 drives the second motor 662, the central rotating plate 663 and each group of side rotating plates 665 to descend until each group of anti-slip pads 666 are all attached to the sample paper. Then, the second motor 662 is started to drive the central rotating plate 663 and each group of side rotating plates 665 to rotate, and the friction force of the anti-slip pads 666 is used to make the sample paper rotate. And when the sample paper rotates, the central rotating plate 663 and each group of side rotating plates 665 distributed in a circular array exert force simultaneously, so that the force on the sample paper is more uniform, avoiding damage to the sample paper, protecting the sample paper, and also improving the fluency of the detection work because the whole process of detection, rotation and bending does not require manual control.

[0065] During detection, the sample paper can be fixed by the extrusion of the upper fixing piece and the lower fixing piece. When the sample paper needs to be rotated, only need to drive the upper fixing piece to rise through the electric slide table 651 to release the fixation of the sample paper. And when the sample paper is rotated, the friction at the edge of the sample paper is also reduced by the groups of rollers 655 arranged at equal intervals along the fan-shaped path, which better assists the paper rotation work, thereby improving the functionality and auxiliary effect of the fixing mechanism 650.

[0066] Based on the above-mentioned environmental protection new material pulp detection device, an embodiment of the present invention also proposes a detection method for the detection device. Exemplarily, the detection method includes: Inject the pulp and the clear water in the water tank into the mixing cylinder at a ratio of 1:5, and then stir in one direction until the pulp and the clear water are completely mixed; Let the mixed liquid stand until the pulp fibers are completely precipitated; Open the electric ball valve, and discharge the clear water in the mixing cylinder into the water tank through each group of micropores; Start the first electric push rod, and drive the mixing cylinder to rise and separate from the mold cylinder through the first electric push rod; Start the second electric push rod, and drive the mold cylinder and the semi-finished sample paper to rise and separate from the electric ball valve through the second electric push rod; Start the first motor, and drive the second extension rod to rotate through the first motor so that the mold cylinder is sleeved on the clamping table to obtain a semi-finished sample paper; Start the third electric push rod, and drive the sampling cover to descend until the sticky paper board abuts against the semi-finished sample paper; Connect the external high-pressure gas to the high-pressure air inlet. The high-pressure gas then acts on the semi-finished sample paper through each group of high-pressure air outlets and micropores, so that the semi-finished sample paper can be loosened from the sample placing plate; Start the servo electric cylinder, drive the paper shoveling block into the sampling cover through the servo electric cylinder, and then pass through from between the semi-finished sample paper and the sample placing plate with the tip to further shovel the semi-finished sample paper out of the sample placing plate; Control the sampling cover to rise, place the sticky paper board in the forming unit for baking until the moisture in the semi-finished sample paper is completely evaporated, thereby obtaining a finished sample paper; Place the sample paper on the detection board, and then start the two groups of electric slide tables to drive the two groups of upper fixing pieces to descend simultaneously, and cooperate with the two groups of lower fixing pieces to clamp both ends of the sample paper, thereby fixing the sample paper; Start the light source. After the light is refracted by the spherical glass cover, it can be emitted radially upward, so that it can act uniformly on the surface of the sample paper; The image information of the sample paper is collected from different angles by the upper groups of camera units. Thus, when light passes through the sample paper, whether there is a shadow on the sample paper is used to detect whether there are impurities in the pulp, so as to judge the quality of the pulp; Two groups of electric angular position platforms drive two groups of articulated plates to deflect, so as to bend the paper, so that small, hidden and deep impurities can leak out by bending the sample paper; Release the fixation of the sample paper, and then drive the second motor, the central rotating plate and each group of side rotating plates to descend through the fourth electric push rod until each group of anti-slip pads are all attached to the sample paper; Start the second motor to drive the central rotating plate and each group of side rotating plates to rotate, and use the friction of the anti-slip pads to make the sample paper rotate, so as to change the bending orientation of the sample paper; After all angles are bent, the detection work is completed.
