Description

Technical Field

[0001] This invention relates to the technical field of testing devices for nylon masterbatch preparation, and in particular to a color detection device and its detection method for the preparation of colored nylon masterbatch. Background Technology

[0002] Color masterbatch, also known as pigment concentrate, is an intermediate product between raw materials and final products. It mainly consists of three parts: carrier resin, colorant, and dispersant, with the pigment content typically ranging from 20% to 70%. Nylon fiber color masterbatch exhibits good quality stability and excellent dispersibility. It can be used directly with mixed resins without contaminating containers; it provides single-color and full-concentration pre-dispersed pigments, facilitating color mixing. It is manufactured using high-quality organic and inorganic pigments and additives. Color detection devices are used to detect the color difference between two color sources. There are two types of color detection devices: colorimeters and spectrophotometers. Colorimeters are designed based on the tristimulus value principle, and the measured value is not the true absolute value of the color. They can only give the color difference value between two samples. Spectrophotometers, on the other hand, are designed based on the spectrophotometric principle and can measure the true absolute value of the color. They have high precision and multi-functionality. Because they can measure the reflectance at each wavelength, they are suitable for complex color analysis. Since colorimeters cannot obtain the absolute value of the color, they cannot establish and manage their own color standard database. Therefore, spectrophotometers are more suitable for measuring the color of colored nylon masterbatches.

[0003] Chinese Patent Publication No. CN213903286U discloses a spectrophotometer. The main body has a detection lens and a clamp on one side. The clamp includes a fixed base mounted on the main body and a support plate rotatably connected to the fixed base. A pressing head is connected to the upper end of the support plate, and the pressing head abuts against the detection lens as the support plate rotates. A rotating shaft is fixed to the lower end of the support plate and rotatably connected within the fixed base. Multiple limiting holes are distributed along the circumference of the rotating shaft on the inner side of the fixed base. A limiting rod is slidably connected to the support plate and inserted into the limiting holes. The limiting rod is parallel to the rotating shaft, and the sliding distance of the limiting rod is greater than the depth of the limiting hole. This application has the effect of stably clamping the object to be tested, which is beneficial to ensuring its detection accuracy.

[0004] The existing technical solutions described above have the following drawbacks: Although they can limit the rotation angle of the support plate to different angles, thereby locking the pressing head to the object to be tested and ensuring the stability of the object to be tested, thus ensuring the detection accuracy, the barium sulfate on the inner wall of the integrating sphere will turn pale yellow after long-term use of the color detection device, affecting the measurement results of the integrating sphere. At this time, it is necessary to replace the integrating sphere to maintain the accuracy of the measurement results, resulting in high maintenance costs. Therefore, we propose a color detection device and detection method for the preparation of colored nylon masterbatch to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a color detection device and method for preparing colored nylon masterbatch, in order to solve the problem mentioned in the background art that the existing color detection device can limit the support plate to different flip angles, thereby realizing the locking work of the pressing head on the object to be tested, so as to ensure the stability of the object to be tested and thus ensure the detection accuracy of the object to be tested. However, when the color detection device is used for a long time, the barium sulfate on the inner wall of the integrating sphere will turn light yellow, affecting the measurement results of the integrating sphere.

The lower end of the electric telescopic cylinder for the baffle passes through the integrating sphere and extends into the interior of the integrating sphere and is fixedly connected to the baffle.

[0015] A detection method for a color detection device used in the preparation of colored nylon masterbatch includes the following steps:

[0016] Step 1: Select a suitable diameter plate according to the color nylon mother material being tested. Place the diameter plate above the second clamping block. By retracting the first electric telescopic cylinder of the diameter plate clamping mechanism, the sliding rod of the diameter plate clamping mechanism moves towards the second electric telescopic cylinder of the diameter plate clamping mechanism, thereby causing the first clamping frame to move down as a whole. The first clamping frame slides into contact with the positioning sleeve of the diameter plate clamping mechanism, so that the first clamping block at the lower end of the first clamping frame is in contact with the second clamping block, thereby clamping the diameter plate. By extending the second electric telescopic cylinders of the two diameter plate clamping mechanisms, the fixed plate of the diameter plate clamping mechanism moves towards the positioning ring. The fixed plate of the diameter plate clamping mechanism drives the first clamping frame and the second clamping frame to move towards the positioning ring until one end of the first clamping frame and the second clamping frame are in contact with the positioning ring. At this time, the diameter plate is placed directly in front of the sample window.

[0017] Step 2: Perform instrument calibration. Place the black cavity on one side of the aperture plate, lift the clamp to hold the black cavity, and run the color detection device to perform black calibration. After calibration, take out the white plate and place it on one side of the aperture plate. Lift the clamp to hold the white plate, and run the color detection device to perform white calibration.

[0018] Step 3: Pour the masterbatch into a round cuvette for measurement. At this time, place the color detection device upright with the sliding detection seat side of the color detection device facing down and the aperture plate facing up. Place the round cuvette on top of the aperture plate.

[0019] Step 4: Perform the measurement. Turn on the pulsed xenon lamp. The light from the pulsed xenon lamp first comes into contact with the lower baffle, which blocks and diffuses the light. The light is evenly distributed after multiple diffuse reflections on the inner wall of the integrating sphere. When the light shines on the circular cuvette, it is reflected by the cuvette. After multiple diffuse reflections, the light enters the second and first light cavities. The first convex lens in the first light cavity disperses the light and is detected by the first optical sensor. The refracting mirror in the second light cavity refracts the light to the second lens, which disperses the light and is detected by the second optical sensor. Simultaneously, two sets of data are acquired: the measurement data of the masterbatch and the reference data of the internal environment. The two sets of data are compared to ensure the accuracy of the data, and the measurement results are displayed on the screen.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, when spraying barium sulfate onto the inner wall of the integrating sphere, the electric telescopic cylinder of the baffle is first retracted to move the baffle up to the inside of the baffle groove. At this time, the coating spraying mechanism is placed in the middle position inside the integrating sphere through the sample window. The electric telescopic cylinder of the coating spraying positioning mechanism is extended, pushing the fixing plate of the coating spraying positioning mechanism closer to the inner wall of the integrating sphere until the universal wheel of the coating spraying positioning mechanism is in contact with the inner wall of the integrating sphere. The setting of twelve coating spraying positioning mechanisms allows the positioning ball to be kept in the center position of the integrating sphere. Since the positioning ball is a solid iron ball, the weight of the positioning ball ensures the stability of the center of gravity of the positioning ball. The electric telescopic cylinder of the grinding mechanism is first extended to cause the grinding disc to... The inner walls of the integrating sphere are aligned. The grinding motor and grinding air pump are activated. The output of the grinding motor drives the grinding disc to rotate, thus grinding the inner wall of the integrating sphere. The suction of the grinding air pump forces air carrying grinding dust through the intake pipe into the filter box. The air carrying grinding dust passes sequentially through the first and second filters, where the dust is filtered to one side. The air is finally discharged through the air pump exhaust pipe. Simultaneously, the first drive motor of the coating spraying mechanism drives the first drive ring of the coating spraying mechanism to rotate vertically. The second drive motor of the coating spraying mechanism drives the second drive ring of the coating spraying mechanism to rotate horizontally. The third drive motor of the coating spraying mechanism drives the third drive ring of the coating spraying mechanism to rotate horizontally. The forward and backward rotation effectively changes the position of the grinding mechanism, allowing it to rotate in any direction. This regular rotation enables the grinding mechanism to grind any position on the inner wall of the integrating sphere. The grinding mechanism grinds the inner wall of the integrating sphere twice. The retraction of the grinding mechanism's electric telescopic cylinder extends the coating spraying assembly's electric telescopic cylinder, which moves the spray box closer to the inner wall of the integrating sphere. Air is drawn in by a pressurized air pump and then introduced into the barium sulfate slurry chamber through the air inlet pipe. The incoming air pushes the push plate upward, allowing the barium sulfate slurry in the chamber to be evenly sprayed from the slurry spray gun. The heating mechanism continuously heats and maintains the temperature of the barium sulfate slurry. To maintain the spraying effect, the rotation of the first, second, and third drive rings of the coating spraying mechanism allows the slurry spray gun to rotate in any direction. This regular rotation allows the grinding mechanism to spray any position on the inner wall of the integrating sphere. The coating spraying assembly sequentially sprays the inner wall of the integrating sphere three times. This solves the problem of existing color detection devices limiting the different rotation angles of the support plate, thus achieving the locking of the pressing head onto the object to be tested, ensuring the stability of the object's contact and guaranteeing the detection accuracy. However, with prolonged use, the barium sulfate on the inner wall of the integrating sphere will turn pale yellow, affecting the measurement results.At this point, it is necessary to replace the integrating sphere to maintain the accuracy of the measurement results, which presents a problem of high maintenance costs.

[0022] 2. In this invention, the caliber plate clamping mechanism clamps the caliber plate, placing it above the second clamping block. The retraction of the first electric telescopic cylinder of the caliber plate clamping mechanism drives the sliding rod of the caliber plate clamping mechanism to move towards the second electric telescopic cylinder, thereby causing the first clamping frame to move downwards as a whole. The first clamping frame is slidably connected to the positioning sleeve of the caliber plate clamping mechanism, allowing the first clamping block at the lower end of the first clamping frame to fit against the second clamping block. The first and second clamping blocks form a 235-degree arc plate. Due to the greater than 235-degree setting, the edge of the caliber plate is inwardly clamped, preventing the caliber plate from falling. The extension of the second electric telescopic cylinders of the two caliber plate clamping mechanisms drives the fixing plate of the caliber plate clamping mechanism to move towards the positioning ring. The fixing plate of the caliber plate clamping mechanism drives the first and second clamping frames to move towards the positioning ring until one end of the first and second clamping frames fits against the positioning ring. The sealing design prevents light leakage at the positioning ring from affecting the detection effect. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

The grinding mechanism 41 is offset. A spray box 44 is provided at the upper end of the coating spraying assembly 42. A barium sulfate slurry chamber 45 is provided inside the spray box 44. A push plate 49 is slidably provided inside the barium sulfate slurry chamber 45. A slurry spray gun 48 is sealed and installed at the upper end of the spray box 44 and is connected to the barium sulfate slurry chamber 45. A first drive motor 37 of the coating spraying mechanism is fixedly installed inside one end of the positioning ball 32. The output end of the first drive motor 37 of the coating spraying mechanism is connected to the first drive ring 33 of the coating spraying mechanism. A second drive motor 38 of the coating spraying mechanism is fixedly installed at the rear side of the front end of the first drive ring 33 of the coating spraying mechanism. The output end of the second drive motor 38 of the coating spraying mechanism is connected to the second drive ring 34 of the coating spraying mechanism. A third drive motor 39 of the coating spraying mechanism is fixedly installed below the upper end of the second drive ring 34 of the coating spraying mechanism and is connected to the third drive ring 35 of the coating spraying mechanism.

[0034] In use, first, retract the electric telescopic cylinder 67 of the baffle to move the baffle 69 upward to the inside of the baffle groove 68. At this time, place the coating spraying mechanism 8 into the middle position inside the integrating sphere 6 through the sample window 5. Extend the electric telescopic cylinder 64 of the coating spraying positioning mechanism 40. The electric telescopic cylinder 64 of the coating spraying positioning mechanism 40 pushes the coating spraying positioning mechanism fixing plate 65 close to the inner wall of the integrating sphere 6 until the universal wheel 66 of the coating spraying positioning mechanism is in contact with the inner wall of the integrating sphere 6. The setting of twelve coating spraying positioning mechanisms 40 allows the positioning ball 32 to be kept in the center position of the integrating sphere 6. Since the positioning ball 32 is a solid iron ball, the weight of the positioning ball 32 ensures the stability of the center of gravity of the positioning ball 32. The electric telescopic cylinder 52 of the grinding mechanism 41 causes the grinding disc 55 to fit against the inner wall of the integrating sphere 6, activating the grinding motor 57 and the grinding air pump 61. The output of the grinding motor 57 drives the grinding disc 55 to rotate, thereby grinding the inner wall of the integrating sphere 6. The suction of the grinding air pump 61 forces air carrying grinding dust into the filter box 54 through the air inlet pipe 58. The air carrying grinding dust passes through the first filter screen 59 and the second filter screen 60 in sequence, and the dust is filtered on one side of the first filter screen 59 and the second filter screen 60. The air is finally discharged through the air pump exhaust pipe 63. At the same time as grinding, the first drive motor 37 of the coating spraying mechanism can drive the first drive ring 33 of the coating spraying mechanism to rotate up and down, and through the second drive ring 33 of the coating spraying mechanism... The drive motor 38 can drive the second drive ring 34 of the coating spraying mechanism to rotate left and right. The third drive motor 39 of the coating spraying mechanism can drive the third drive ring 35 of the coating spraying mechanism to rotate forward and backward. This effectively changes the position of the grinding mechanism 41, allowing it to rotate in any direction. With regular circular rotation, the grinding mechanism 41 can perform grinding operations on any position of the inner wall of the integrating sphere 6. The grinding mechanism 41 grinds the inner wall of the integrating sphere 6 twice. The electric telescopic cylinder 52 of the grinding mechanism 41 retracts, and the electric telescopic cylinder 31 of the coating spraying assembly 42 extends. The electric telescopic cylinder 31 of the coating spraying positioning mechanism drives the spray box 44 towards the integrating sphere. The inner wall of the sphere 6 is close to the air pump 50, which absorbs air and then inputs it into the barium sulfate slurry chamber 45 through the air inlet pipe 51. The incoming air pushes the push plate 49 to move upward, so that the barium sulfate slurry in the barium sulfate slurry chamber 45 is evenly sprayed out from the slurry spray gun 48. The heating mechanism 46 can continuously heat and keep the barium sulfate slurry warm to maintain the spraying effect. The rotation of the first drive ring 33, the second drive ring 34 and the third drive ring 35 of the coating spraying mechanism allows the slurry spray gun 48 to rotate in any direction. With the regular rotation, the grinding mechanism 41 can spray any position on the inner wall of the integrating sphere 6. The coating spraying component 42 is applied to the inner wall of the integrating sphere 6 three times in sequence.

[0040] Please see Figure 4 and Figure 8 A pulsed xenon lamp 7 is installed above the integrating sphere 6, and a baffle 69 is provided below the pulsed xenon lamp 7.

[0041] A detection method for a color detection device used in the preparation of colored nylon masterbatch includes the following steps:

[0042] Step 1: Select a suitable diameter plate 19 based on the tested colored nylon mother material. Place the diameter plate 19 above the second clamping block 30. The first electric telescopic cylinder 27 of the diameter plate clamping mechanism moves the sliding rod 24 of the diameter plate clamping mechanism towards the second electric telescopic cylinder 28, thereby causing the first clamping frame 20 to move downwards as a whole. The first clamping frame 20 is slidably connected to the positioning sleeve 23 of the diameter plate clamping mechanism, allowing the first clamping block 21 at the lower end of the first clamping frame 20 to... The second clamping block 30 is in contact with the plate, thereby clamping the caliber plate 19. The extension of the second electric telescopic cylinder 28 of the two caliber plate clamping mechanisms drives the caliber plate clamping mechanism fixing plate 22 to move towards the positioning ring 18. The caliber plate clamping mechanism fixing plate 22 drives the first clamping frame 20 and the second clamping frame 29 to move towards the positioning ring 18 until one end of the first clamping frame 20 and the second clamping frame 29 is in contact with the positioning ring 18. At this time, the caliber plate 19 is placed directly in front of the sample window 5.

[0043] Step 2: Perform instrument calibration. Place the black cavity on one side of the aperture plate 19, lift the clamp 17 to clamp the black cavity, and run the color detection device to perform black calibration. After calibration, take out the white plate and place it on one side of the aperture plate 19. Lift the clamp 17 to clamp the white plate, and run the color detection device to perform white calibration.

[0044] Step 3: Pour the masterbatch into a round cuvette for measurement. At this time, place the color detection device body 1 upright, with one side of the sliding detection seat 2 of the color detection device body 1 facing down, and the aperture plate 19 placed above the color detection device body 1. Place the round cuvette above the aperture plate 19.

[0045] Step 4: Perform the measurement. Turn on the pulsed xenon lamp 7. The light from the pulsed xenon lamp 7 first comes into contact with the lower baffle 69. The baffle 69 blocks and diffuses the light. The light is evenly distributed after multiple diffuse reflections on the inner wall of the integrating sphere 6. When the light shines on the circular cuvette, it is reflected by the circular cuvette. After multiple diffuse reflections, the light reflected by the circular cuvette enters the second light cavity 9 and the first light cavity 13. The first convex lens 14 in the first light cavity 13 disperses the light and detects it through the first optical sensor 15. The refracting mirror 10 in the second light cavity 9 refracts the light to the second lens 11. The second lens 11 disperses the light and detects it through the second optical sensor 12. At the same time, two kinds of data are acquired: the measurement data of the masterbatch and the internal environment reference data. The two data are compared to ensure the accuracy of the data and the measurement results are displayed on the display screen 3.

[0046] Working principle: When spraying barium sulfate onto the inner wall of the integrating sphere 6, the electric telescopic cylinder 67 first retracts, causing the baffle 69 to move upwards to the inside of the baffle groove 68. At this time, the coating spraying mechanism 8 is placed in the middle position inside the integrating sphere 6 through the sample window 5. The electric telescopic cylinder 64 of the coating spraying positioning mechanism 40 is extended, pushing the coating spraying positioning mechanism fixing plate 65 closer to the inner wall of the integrating sphere 6 until the universal wheel 66 of the coating spraying positioning mechanism is in contact with the inner wall of the integrating sphere 6. The arrangement of twelve coating spraying positioning mechanisms 40 allows the positioning ball 32 to remain in the center position of the integrating sphere 6. Since the positioning ball 32 is a solid iron ball, its weight ensures that the positioning ball... 32. To stabilize the center of gravity, the electric telescopic cylinder 52 of the grinding mechanism 41 first extends, causing the grinding disc 55 to fit against the inner wall of the integrating sphere 6. The grinding motor 57 and grinding air pump 61 are then activated. The output of the grinding motor 57 drives the grinding disc 55 to rotate, thus grinding the inner wall of the integrating sphere 6. The suction of the grinding air pump 61 forces air carrying grinding dust through the air inlet pipe 58 into the filter box 54. The air carrying grinding dust passes sequentially through the first filter screen 59 and the second filter screen 60, filtering the dust on one side of the first filter screen 59 and the second filter screen 60. Finally, the air is discharged through the air pump exhaust pipe 63. Simultaneously, the first drive motor 37 of the coating spraying mechanism drives the first drive ring 33 of the coating spraying mechanism to rotate vertically. The second drive motor 38 of the coating spraying mechanism can drive the second drive ring 34 of the coating spraying mechanism to rotate left and right. The third drive motor 39 of the coating spraying mechanism can drive the third drive ring 35 of the coating spraying mechanism to rotate forward and backward. This effectively changes the position of the grinding mechanism 41, allowing it to rotate in any direction. With regular circular rotation, the grinding mechanism 41 can perform grinding operations on any position of the inner wall of the integrating sphere 6. The grinding mechanism 41 grinds the inner wall of the integrating sphere 6 twice. The electric telescopic cylinder 52 of the grinding mechanism 41 retracts, and the electric telescopic cylinder 31 of the coating spraying assembly 42 extends. The electric telescopic cylinder 31 of the coating spraying positioning mechanism drives the spray box 44. The air is drawn towards the inner wall of the integrating sphere 6 by the pressurized air pump 50 and then introduced into the barium sulfate slurry chamber 45 through the air inlet pipe 51. The incoming air pushes the push plate 49 upward, thereby allowing the barium sulfate slurry in the barium sulfate slurry chamber 45 to be evenly sprayed out from the slurry spray gun 48. The heating mechanism 46 continuously heats and keeps the barium sulfate slurry at a constant temperature to maintain the spraying effect. The rotation of the first drive ring 33, the second drive ring 34, and the third drive ring 35 of the coating spraying mechanism allows the slurry spray gun 48 to rotate in any direction. With the regular rotation, the grinding mechanism 41 can perform spraying operations on any position on the inner wall of the integrating sphere 6. The coating spraying assembly 42 sequentially coats the inner wall of the integrating sphere 6 three times.After spraying is completed, the electric telescopic cylinder 31 of the coating spraying positioning mechanism shrinks, and the coating spraying mechanism 8 can be removed.
