[0007] As a preferred technical solution of the present invention, a connecting belt is sleeved on the outer side of pulley one, and the internal transmission of the connecting belt is connected to pulley two. The diameter of the connecting belt is equal to that of pulley two, and a connecting gear is fixedly installed in front of pulley two, and the connecting gear is located on the right side of the driving gear.

There are three storage bins, and the three storage bins are all located inside the detection box.

[0010] As a preferred technical solution of the present invention, there are three connecting shafts, which are respectively located inside the three storage bins, there are two pulleys and two connecting gears, and the three connecting shafts are respectively fixedly connected to the driving gear and the two connecting gears.

[0011] As a preferred technical solution of the present invention, there are three driven gears, screws, fixed blocks, nuts and detectors, the three driven gears are respectively engaged with the driving gear and the two connecting gears, and the three detectors are respectively located above the three storage bins.

[0012] As a preferred technical solution of the present invention, there are multiple fixed blocks, all of which are located above the detection box, and all of the three lead screws pass through the interior of the multiple fixed blocks.

[0013] A detection method of a plastic pigment particle color difference detection system comprises the following steps:

[0014] First, the storage bin is installed inside the detection box through the sliding action of the slider 1 and the slide groove 1. At the same time, since the connecting shaft is driven by the driving gear and the connecting gear and is fixed inside the detection box, the surface is cylindrical and the middle is hollow. Therefore, when the storage bin is installed, it will pass through the connecting shaft and be located inside the storage bin.

[0015] At this time, insert the stirring rod into the interior of the connecting shaft and fix the stirring rod and the connecting shaft with bolts. At the same time, since the connecting shaft is located inside the storage bin, after the stirring rod is installed, it will be inside the storage bin and biased towards the bottom of the storage bin.

[0016] After the installation is completed, pour the different batches of plastic pigment particles that need to be tested into the storage bin respectively, so that the plastic pigment particles cover the stirring rod. Then turn on the detector. Since the detector is located above the storage bin, the plastic pigment particles at the bottom can be quickly tested.

[0017] During the test, the motor is started to drive the output shaft to rotate, so that the output shaft drives the driving gear and the connecting shaft to rotate. When the connecting shaft rotates, the stirring rod will stir and push the plastic pigment particles covered on the surface, and turn the plastic pigment particles at the bottom to the surface, so as to facilitate the subsequent detection of plastic pigment particles at different positions by the detector, thereby achieving the effect of improving the detection accuracy. At the same time, when the driving gear rotates, it will mesh with the driven gear and drive the driven gear to rotate. At this time, since the driven gear and the lead screw are fixedly connected, the lead screw and the nut are meshed, so that the nut drives the detector to move back and forth, so as to detect plastic pigment particles at different positions;

[0018] At this time, when the output shaft rotates, the pulley 1 is fixedly connected to the output shaft, and the rotation of the connecting belt drives the pulley 2 and the connecting gear to rotate, so that one driving force can simultaneously drive the driving gear and the two connecting gears to rotate and mesh with the three driven gears, thereby achieving the effect of simultaneous detection;

[0019] Finally, when plastic pigment particles with color difference are detected, they are uniformly processed for secondary treatment to facilitate subsequent use.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention has an output shaft fixedly mounted on the output end of the motor, a pulley 1 fixedly mounted in front of the output shaft, a driving gear fixedly mounted in front of the pulley 1, a connecting shaft fixedly mounted in front of the driving gear, and the connecting shaft is plugged into the storage bin. A stirring rod is fixedly mounted inside the connecting shaft, and a bolt is engaged with the rear side of the stirring rod, and the bolt is engaged with the connecting shaft. When the color of the plastic pigment particles is detected, the motor is first started to drive the output shaft to rotate. At this time, since the pulley 1 and the driving gear are fixedly mounted in front of the output shaft, and the connecting shaft is fixedly mounted in front of the driving gear, and the connecting shaft passes through the storage bin and is located inside the detection box, the output shaft drives the connecting shaft to rotate. At this time, since the stirring rod can be plugged into the inside of the connecting shaft, and the stirring rod is fixed to the connecting shaft by a bolt, when the plastic pigment particles are placed inside the storage bin, they are driven to rotate by the connecting shaft through the stirring rod during detection, thereby turning the plastic pigment particles inside the storage bin, achieving the effect of being able to detect the plastic pigment particles at the bottom.

[0022] 2. The present invention comprises a driven gear meshing with the outside of the driving gear, a lead screw fixedly installed in front of the driven gear, a fixed block sleeved on the outside of the lead screw, and the fixed block fixed on the top of the detection box, and a nut meshing with the outside of the lead screw, and a detector fixedly installed at the bottom of the nut. After the motor is started to drive the output shaft and the driving gear to rotate, the driving gear rotates through the meshing action with the driven gear, and since the driven gear is fixedly connected to the lead screw, the lead screw is driven to mesh with the nut. At this time, the nut moves back and forth under the meshing action with the lead screw, driving the detector to detect the plastic pigment particles at different positions inside the storage bin, thereby achieving the effect of increasing the detection accuracy.

[0023] 3. The present invention provides a storage bin within the test box, which is mounted by the sliding action of a slider and a slot. There are three storage bins and three detectors, each with three lead screws positioned above the three bins. When different batches of plastic particles need to be tested, different plastic pigment particles can be placed in different storage bins, allowing the three detectors to simultaneously test the three batches of plastic pigment particles, thereby improving overall testing efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1 to 7 As shown, the present invention provides a plastic pigment particle color difference detection system, including a detection box 1, a slide groove 2 is opened inside the detection box 1, a slider 3 is slidably connected inside the slide groove 2, a storage bin 4 is fixedly installed on the inner side of the slider 3, the storage bin 4 is located inside the detection box 1, a handle 5 is fixedly installed in front of the storage bin 4, a support plate 6 is fixedly installed at the rear of the detection box 1, a motor 7 is fixedly installed at the rear of the support plate 6, a transmission assembly is provided at the rear of the detection box 1, the transmission assembly includes an output shaft 8, the output shaft 8 is fixedly installed at the output end of the motor 7, a pulley 9 is fixedly installed in front of the output shaft 8, a driving gear 10 is fixedly installed in front of the pulley 9, a connecting shaft 11 is fixedly installed in front of the driving gear 10, the connecting shaft 11 is plugged into the storage bin 4, a stirring rod 12 is fixedly plugged into the interior of the connecting shaft 11, the rear side of the stirring rod 12 is meshed with a bolt 13, and the bolt 13 is meshed with the connecting shaft 11.

[0034] First, when detecting the color of the plastic pigment particles, the motor 7 is started to drive the output shaft 8 to rotate. At this time, since a pulley 9 and a driving gear 10 are fixedly installed in front of the output shaft 8, and a connecting shaft 11 is fixedly installed in front of the driving gear 10, and the connecting shaft 11 passes through the storage bin 4 and is located inside the detection box 1, the output shaft 8 drives the connecting shaft 11 to rotate. At this time, since a stirring rod 12 can be inserted into the interior of the connecting shaft 11, the stirring rod 12 is fixed to the connecting shaft 11 by a bolt 13. When the plastic pigment particles are placed in the storage bin 4, they will be driven to rotate by the connecting shaft 11 through the stirring rod 12 during detection, thereby turning over the plastic pigment particles inside the storage bin 4, so that the plastic pigment particles at the bottom can be detected.

[0035] Among them, the outer side of the driving gear 10 is engaged with the driven gear 14, and a screw 15 is fixedly installed in front of the driven gear 14. The outer side of the screw 15 is sleeved with a fixed block 16, and the fixed block 16 is fixed above the detection box 1. The outer side of the screw 15 is engaged with a nut 17, and a detector 18 is fixedly installed at the bottom of the nut 17.

[0036] After the starting motor 7 drives the output shaft 8 and the driving gear 10 to rotate, the driving gear 10 rotates through the meshing action with the driven gear 14. Since the driven gear 14 is fixedly connected to the lead screw 15, the lead screw 15 is driven to mesh with the nut 17. At this time, the nut 17 moves back and forth under the meshing action with the lead screw 15, driving the detector 18 to detect the plastic pigment particles at different positions inside the storage bin 4, thereby achieving the effect of increasing the detection accuracy.

[0037] A second slide groove 19 is provided inside the detection box 1 , and a second slider 20 is slidably connected inside the second slide groove 19 . The second slider 20 is fixedly connected to the detector 18 .

[0038] The main function of the second slide groove 19 is to limit the detector 18 and the nut 17, ensuring that the detector 18 can move forward and backward while preventing the detector 18 from rotating during the engagement process between the nut 17 and the lead screw 15.

[0039] Among them, the outer side of pulley 1 9 is sleeved with a connecting belt 21, the internal transmission of the connecting belt 21 is connected to pulley 2 22, the diameter of the connecting belt 21 is equal to that of the pulley 2 22, and a connecting gear 23 is fixedly installed in front of the pulley 2 22, and the connecting gear 23 is located on the right side of the driving gear 10.

[0040] After the starting motor 7 drives the pulley 1 9 to rotate, since the outer side of the pulley 1 9 is connected with the connecting belt 21, it will drive the connecting belt 21 to transmit. At this time, the connecting belt 21 will drive the connecting gear 23 to rotate through the transmission effect with the pulley 2 22, thereby achieving the effect of driving multiple structures to rotate with only one driving power.

[0041] Among them, a fixed plate 24 is fixedly installed at the rear of the detection box 1, a telescopic shaft 25 is fixedly installed at the bottom of the fixed plate 24, a spring 26 is sleeved on the outside of the telescopic shaft 25, a connecting block 27 is fixedly installed at the bottom of the spring 26, and a tensioning wheel 28 is rotatably connected to the inside of the connecting block 27.

[0042] The spring 26 will generate a certain elastic force to squeeze the connecting block 27 downward. At this time, the tensioner 28 will contact the top of the connecting belt 21, so that the connecting belt 21 is always kept in a tensioned state, thereby facilitating the stable driving of the pulley 22.

[0043] There are multiple chutes 2 and sliders 3, and the multiple chutes 2 and sliders 3 are all located inside the detection box 1. There are three storage bins 4, and the three storage bins 4 are all located inside the detection box 1.

[0044] The three storage bins 4 are respectively installed to the interior of the detection box 1 through multiple sliders 3 and the storage bins 4. When different batches of plastic particles need to be tested, different plastic pigment particles can be placed in different storage bins 4, so that three batches of plastic pigment particles can be tested at the same time, thereby improving the overall detection efficiency.

[0045] Among them, there are three connecting shafts 11, which are respectively located inside the three storage bins 4, and there are two pulleys 22 and two connecting gears 23. The three connecting shafts 11 are respectively fixedly connected to the driving gear 10 and the two connecting gears 23.

[0046] The two connecting gears 23 are connected to the connecting belt 21 through the two pulleys 22 to achieve synchronous rotation and increase the overall detection efficiency.

[0047] Among them, there are three driven gears 14, screws 15, fixing blocks 16, nut 17 and detectors 18. The three driven gears 14 are respectively engaged with the driving gear 10 and the two connecting gears 23. The three detectors 18 are respectively located above the three storage bins 4.

[0048] The main function of the three detectors 18 is to simultaneously detect the plastic pigment particles inside the three storage bins 4, thereby increasing the detection efficiency. At the same time, during the engagement process of the three nuts 17 and the three screws 15, the three detectors 18 can detect different positions inside the three storage bins 4, thereby increasing the accuracy of the detection.

[0049] There are multiple fixing blocks 16 , all of which are located above the detection box 1 , and all of the three lead screws 15 pass through the interior of the multiple fixing blocks 16 .

[0050] The main function of the multiple fixing blocks 16 is to support the three lead screws 15 to keep the lead screws 15 stable, and at the same time facilitate the three driven gears 14 to engage with the two connecting gears 23 and the driving gear 10 respectively.

[0051] A detection method of a plastic pigment particle color difference detection system comprises the following steps:

[0052] First, the storage bin 4 is installed into the interior of the detection box 1 through the sliding action of the slider 1 and the slide groove 1. At the same time, since the connecting shaft 11 is driven by the driving gear 10 and the connecting gear 23 and fixed inside the detection box 1, the surface is cylindrical and the middle is hollow. Therefore, when the storage bin 4 is installed, it will pass through the connecting shaft 11, so that the connecting shaft 11 is located inside the storage bin 4;

[0053] At this time, the stirring rod 12 is inserted into the interior of the connecting shaft 11, and the stirring rod 12 and the connecting shaft 11 are fixed by the bolt 13. At the same time, since the connecting shaft 11 is located inside the storage bin 4, after the stirring rod 12 is installed, it will be inside the storage bin 4 and biased towards the bottom of the storage bin 4;

[0054] After the installation is completed, different batches of plastic pigment particles to be tested are poured into the storage bin 4 so that the plastic pigment particles cover the stirring rod 12. At this time, the detector 18 is turned on. Since the detector 18 is located above the storage bin 4, the plastic pigment particles at the bottom can be quickly tested.

[0055] During the detection, the motor 7 is started to drive the output shaft 8 to rotate, so that the output shaft 8 drives the driving gear 10 and the connecting shaft 11 to rotate. When the connecting shaft 11 rotates, the stirring rod 12 will stir and push the plastic pigment particles covered on the surface, and flip the plastic pigment particles at the bottom to the surface, thereby facilitating the subsequent detection of plastic pigment particles at different positions by the detector 18, thereby achieving the effect of improving the detection accuracy. At the same time, when the driving gear 10 rotates, it will mesh with the driven gear 14, driving the driven gear 14 to rotate. At this time, since the driven gear 14 is fixedly connected to the lead screw 15, the lead screw 15 is meshed with the nut 17, so that the nut 17 drives the detector 18 to move back and forth, and the plastic pigment particles at different positions are detected;

[0056] At this time, when the output shaft 8 rotates, the pulley 1 9 is fixedly connected to the output shaft 8, and the rotation of the connecting belt 21 drives the pulley 2 22 and the connecting gear 23 to rotate, so that one driving force can simultaneously drive the driving gear 10 and the two connecting gears 23 to rotate and mesh with the three driven gears 14, thereby achieving the effect of simultaneous detection;

[0057] Finally, when plastic pigment particles with color difference are detected, they are uniformly processed for secondary treatment to facilitate subsequent use.
