Description

Technical Field

[0001] This invention relates to the field of materials processing equipment technology, specifically to a processing device for cellulose nanocrystal composite circularly polarized phosphorescent materials. Background Technology

[0002] Circularly polarized phosphorescent (CPL) materials have become a research hotspot in recent years due to their unique application value in fields such as 3D display, optical anti-counterfeiting, and biosensing. Cellulose nanocrystals (CNC), as a natural and renewable chiral template, can induce phosphorescent molecules to generate a circular polarization response through their self-assembled helical structure, making them an ideal substrate for preparing high-performance CPL materials.

[0003] However, the existing devices have the following shortcomings during use: In the existing processing of cellulose nanocrystal composite circularly polarized phosphorescent materials, there is a lack of targeted orientation control components. Phosphorescent molecules are difficult to align in an orderly manner following the helical orientation of the CNC matrix. Instead, they exhibit random dispersion, local aggregation, or disordered orientation. Consequently, the chiral induction effect of CNC cannot be fully utilized, resulting in insufficient synergy of the circular polarization response of phosphorescent molecules in the composite system and low CPL performance.

[0004] Therefore, we propose a cellulose nanocrystal composite circularly polarized phosphorescent material processing device to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a processing device for cellulose nanocrystal composite circularly polarized phosphorescent materials. A third servo motor drives a bidirectional threaded rod to rotate, which in turn moves an adjusting block along a guide rod, thereby adjusting the distance between two permanent magnets to facilitate changes in magnetic field strength and distribution. A magnetometer on a quartz tube collects magnetic field parameters in real time and feeds them back to a PLC controller, achieving precise closed-loop control of the magnetic field. The directional magnetic field can guide phosphorescent molecules to align in an orderly manner following the helical structure of the CNC matrix, thus solving the problems mentioned in the background art.

A third servo motor for driving the bidirectional threaded rod to rotate is fixedly mounted on one side of one of the support plates.

[0007] Preferably, the quantitative raw material supply mechanism includes three storage tanks and three metering pumps installed on the top of the base plate. The input ends of the three metering pumps are fixedly connected to three extraction pipes, and the ends of the three extraction pipes away from the three metering pumps are connected to the interior of the three storage tanks. The output ends of the three metering pumps are all connected to the interior of the mixing tank through pipes.

[0008] Preferably, the tops of the three storage tanks are fixedly connected to three feed pipes, and each of the three extraction pipes and the three feed pipes is equipped with a first solenoid valve.

[0009] Preferably, the high-efficiency mixing mechanism includes a first servo motor fixedly installed on the top of the tank lid, the output end of the first servo motor movably passing through the tank lid and fixedly connected to a first stirring shaft.

[0010] Preferably, a circular plate is fixedly sleeved on the outer surface of the first stirring shaft, and two second stirring shafts are connected to the top of the circular plate through bearings. Two spur gears are fixedly sleeved on the outer surfaces of the two second stirring shafts, and an internal gear is fixedly connected to the inner surface of the tank cover. The two spur gears mesh with the internal gears.

[0011] Preferably, multiple stirring paddles are fixedly sleeved on the outer surfaces of the two second stirring shafts and the first stirring shaft, and an annular groove is formed on the inner surface of the tank cover, with a circular plate slidably connected in the annular groove.

[0012] Preferably, the pick-up and maintenance mechanism includes three fixed frames fixedly connected to the top of the base plate. One of the fixed frames has a one-way threaded rod rotatably connected to its inner side, and the other two fixed frames have two fixed rods fixedly connected to their inner sides. The inner sides of the three fixed frames are provided with three limiting grooves. The outer surfaces of the one-way threaded rod and the two fixed rods are fitted with three lifting plates, and the three lifting plates are slidably connected in the three limiting grooves.

[0013] Preferably, the top of the three lifting plates is fixedly connected to three connecting frames, and the three connecting frames are fixedly connected to the outer surface of the can lid. The top of one of the fixed frames is fixedly installed with a second servo motor for driving the rotation of the one-way threaded rod. One of the lifting plates is threadedly connected to the one-way threaded rod, and the other two lifting plates are slidably connected to the two fixed rods.

[0014] Preferably, the discharge mechanism includes a discharge pump fixedly installed on the top of the base plate, the input end of the discharge pump is fixedly connected to a discharge pipe, the end of the discharge pipe away from the discharge pump is connected to the interior of the mixing tank, a second solenoid valve is installed on the discharge pipe, and the quartz tube is fixedly connected to the output end of the discharge pump.

[0015] Preferably, the top of the mixing tank is provided with a groove, the bottom of the tank cover is fixedly installed with a sealing ring, the two support plates are fixedly connected to the top of the base plate, and one end of the quartz tube is fixedly connected to a conveying pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention features an adjustable magnetic field monitoring and orientation mechanism. A third servo motor drives a bidirectional threaded rod to rotate, which in turn moves an adjusting block along a guide rod, thereby adjusting the distance between the two permanent magnets. This facilitates changes in the magnetic field strength and distribution. A magnetometer on a quartz tube collects magnetic field parameters in real time and feeds them back to the PLC controller, achieving precise closed-loop control of the magnetic field. The directional magnetic field can guide phosphorescent molecules to align in an orderly manner following the helical structure of the CNC matrix, improving the performance of the circularly polarized phosphorescent material in the composite system. This invention solves the problem of insufficient targeted orientation control components in the existing processing of cellulose nanocrystal composite circularly polarized phosphorescent materials. As a result, phosphorescent molecules cannot align in an orderly manner following the helical orientation of the CNC matrix, instead exhibiting random dispersion, local aggregation, or disordered orientation. Consequently, the chiral induction effect of CNC cannot be fully utilized, leading to insufficient synergy in the circular polarization response of phosphorescent molecules in the composite system and low CPL performance.

[0017] 2. This invention, by setting up a quantitative raw material supply mechanism and a high-efficiency mixing mechanism, uses three metering pumps to extract raw materials from different storage tanks. With the help of the first solenoid valves on the extraction pipe and the feed pipe, it achieves precise proportional delivery of raw materials such as cellulose nanocrystals and phosphorescent molecules, avoiding defects in the composite system caused by material deviation. At the same time, the high-efficiency mixing mechanism adopts a main stirring and auxiliary stirring collaborative design. The first servo motor drives the first stirring shaft to perform axial stirring, and the second stirring shaft driven by the circular plate achieves rotation through the meshing of spur gear and internal gear, forming all-round stirring in the radial and axial directions. This allows the raw materials to fully contact and be evenly dispersed in the mixing tank, avoiding local agglomeration of phosphorescent molecules in the device.

[0018] 3. This invention achieves automated lifting and lowering of the can lid by setting up a pick-and-place maintenance mechanism and a discharge mechanism. The second servo motor drives the unidirectional threaded rod to rotate, causing the lifting plate to slide along the fixed rod and the limiting groove. The can lid is lifted and lowered through the connecting frame, eliminating the need for manual handling and facilitating cleaning and maintenance operations. The discharge mechanism, through the precise cooperation of the discharge pump and the second solenoid valve, stably delivers the uniformly mixed raw materials to the quartz tube for orientation treatment. After that, it is directly output to the feed end of the calender through the conveying pipe. The calender rolls the film to form the film. The formed film then enters the cooling roller group for cooling and shaping, thus completing the CNC composite CPL material film. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1-9 As shown, the present invention provides a technical solution: a cellulose nanocrystal composite circularly polarized phosphorescent material processing device, including a base plate 1, a mixing tank 2 installed on the top of the base plate 1, a tank cover 3 provided on the top of the mixing tank 2, a quantitative raw material supply mechanism 4 provided on the top of the base plate 1 for conveying each raw material into the mixing tank 2 in a precise ratio, a high-efficiency mixing mechanism 5 provided on the inner top of the tank cover 3 for mixing each raw material inside the mixing tank 2, a pick-and-place maintenance mechanism 6 and a discharge mechanism 7 provided on the top of the base plate 1, the discharge mechanism 7 is used to discharge the mixed raw material inside the mixing tank 2, an adjustable magnetic intensity monitoring orientation mechanism 8 is provided at one end of the discharge mechanism 7, and a PLC controller 9 is installed on the outer surface of the mixing tank 2, the wiring terminals of the PLC controller 9 are connected to the device wiring harness; The adjustable magnetic intensity monitoring orientation mechanism 8 includes a quartz tube 801 and two support plates 802. A guide rod 803 is fixedly connected between the two support plates 802, and a bidirectional threaded rod 804 is rotatably connected between the two support plates 802. Two adjusting blocks 805 are threadedly installed on the outer surfaces of the guide rod 803 and the bidirectional threaded rod 804. Two arc-shaped seats 806 are bolted to one end of the two adjusting blocks 805. Two permanent magnets 807 are embedded on the inner surfaces of the two arc-shaped seats 806. A mounting base 808 is fixedly connected to the outer surface of the quartz tube 801. A magnetometer 809 is installed on the top of the mounting base 808. A third servo motor 810 for driving the bidirectional threaded rod 804 to rotate is fixedly installed on one side of one of the support plates 802.

[0023] like Figure 1 and Figure 2 As shown, the quantitative raw material supply mechanism 4 includes three storage tanks 401 and three metering pumps 402 installed on the top of the base plate 1. The input ends of the three metering pumps 402 are fixedly connected to three extraction pipes 403, and the ends of the three extraction pipes 403 away from the three metering pumps 402 are connected to the interior of the three storage tanks 401. The output ends of the three metering pumps 402 are all connected to the interior of the mixing tank 2 through pipes. By setting three independent storage tanks 401 and three metering pumps 402 in a one-to-one correspondence, the classified storage and separate transportation of cellulose nanocrystals, phosphorescent molecules and other auxiliary raw materials can be realized, avoiding performance degradation caused by pre-mixing different raw materials. The extraction pipes 403 are directly connected to the storage tanks 401 and the metering pumps 402, shortening the raw material transportation path and reducing residual loss. The metering pumps 402 accurately control the transportation flow and total amount of each raw material, and work with the PLC controller 9 to realize automatic batching according to the preset ratio, avoiding errors from manual batching from the source and ensuring the consistency of the composition of the composite system.

[0024] like Figure 1 and Figure 2 As shown, the tops of the three storage tanks 401 are fixedly connected to three feed pipes 404. The three extraction pipes 403 and the three feed pipes 404 are all equipped with first solenoid valves 405. The feed pipes 404 at the top of the storage tanks 401 provide a convenient channel for replenishing raw materials. The first solenoid valves 405 on the extraction pipes 403 and the feed pipes 404 can precisely control the feeding and extraction of raw materials.

[0025] like Figure 1 . Figure 3 and Figure 4As shown, the high-efficiency mixing mechanism 5 includes a first servo motor 501 fixedly installed on the top of the tank cover 3. The output end of the first servo motor 501 movably passes through the tank cover 3 and is fixedly connected to a first stirring shaft 502. The first servo motor 501 has the advantages of precise speed adjustment and stable power output. It can flexibly adjust the stirring speed according to the characteristics of the raw materials (such as viscosity and particle size) to adapt to the mixing needs of different composite systems. The first stirring shaft 502 is driven by the first servo motor 501 and can drive the stirring paddle 507 to perform axial deep stirring of the raw materials in the mixing tank 2, initially breaking up the raw material agglomerates, providing a basis for the subsequent radial stirring of the second stirring shaft 504, and improving the overall mixing efficiency.

[0026] like Figure 1 , Figure 4 and Figure 5 As shown, a circular plate 503 is fixedly sleeved on the outer surface of the first stirring shaft 502. Two second stirring shafts 504 are connected to the top of the circular plate 503 via bearings. Two spur gears 505 are fixedly sleeved on the outer surfaces of the two second stirring shafts 504. An internal gear 506 is fixedly connected to the inner surface of the tank cover 3. The two spur gears 505 mesh with the internal gear 506, providing stable support for the second stirring shafts 504 through the circular plate 503, and simultaneously revolving synchronously with the first stirring shaft 502. The meshing transmission design of the spur gears 505 and the internal gear 506 enables the second stirring shafts 504 to rotate during their revolution, covering the entire space of the mixing tank 2 and eliminating dead zones in the mixing. This transmission structure does not require an additional power source; it can achieve two-dimensional mixing by relying on the power of the first stirring shaft 502. This simplifies the mechanism design while ensuring that the raw materials can fully contact each other in both the radial and axial directions, solving the problem of local aggregation of phosphorescent molecules.

[0027] like Figure 1 , Figure 4 and Figure 7 As shown, multiple stirring paddles 507 are fixedly sleeved on the outer surfaces of the two second stirring shafts 504 and the first stirring shaft 502. An annular groove 508 is formed on the inner surface of the tank cover 3, and a circular plate 503 is slidably connected in the annular groove 508. The multiple stirring paddles 507 are evenly distributed on the first stirring shaft 502 and the second stirring shaft 504, which expands the contact area of ​​the raw materials, improves the fineness of the stirring, and further breaks up the micro-agglomerates, so that the cellulose nanocrystals and phosphorescent molecules can be uniformly dispersed at the molecular level. The annular groove 508 in the tank cover 3 plays a limiting and guiding role for the circular plate 503, avoiding the collision of the stirring paddles 507 with the inner wall of the mixing tank 2 caused by the displacement of the circular plate 503 during the stirring process, thus ensuring the stability and safety of the stirring process. The sliding connection between the circular plate 503 and the annular groove 508 reduces transmission friction, reduces mechanical wear, and extends the service life of the equipment.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, the pick-up and maintenance mechanism 6 includes three fixed frames 601 fixedly connected to the top of the base plate 1. One fixed frame 601 has a one-way threaded rod 602 rotatably connected to its inner side, and the other two fixed frames 601 have two fixed rods 603 fixedly connected to their inner sides. The three fixed frames 601 have three limiting grooves 604 on their inner sides. The one-way threaded rod 602 and the two fixed rods 603 are fitted with three lifting plates 605. The three lifting plates 605 are slidably connected in the three limiting grooves 604. The three fixed frames 601 provide a stable support structure for the lifting of the can lid 3, avoiding equipment deformation caused by unilateral force. The one-way threaded rod 602 and the two fixed rods 603 form a lifting structure, ensuring that the lifting plates 605 move smoothly in a straight line. The sliding cooperation between the limiting grooves 604 and the lifting plates 605 further restricts the lifting direction, prevents the can lid 3 from tilting when lifting, ensures the precise docking of the can lid 3 and the mixing tank 2, and improves the sealing reliability.

[0029] like Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, three connecting frames 606 are fixedly connected to the top of the three lifting plates 605, and the three connecting frames 606 are fixedly connected to the outer surface of the tank cover 3. A second servo motor 607 for driving the rotation of the one-way threaded rod 602 is fixedly installed on the top of one of the fixed frames 601. One of the lifting plates 605 is threadedly connected to the one-way threaded rod 602, and the other two lifting plates 605 are slidably connected to the two fixed rods 603. The three lifting plates 605 are firmly connected to the tank cover 3 through the connecting frames 606, so that the tank cover 3 is subjected to uniform force, avoids deformation of the tank cover 3 during the lifting process, and ensures the fit between the sealing ring 11 and the groove 10 of the mixing tank 2. The second servo motor 607 drives the one-way threaded rod 602 to rotate, realizing the automatic lifting of the tank cover 3 without manual handling, reducing the labor intensity of cleaning, maintenance and raw material replenishment of the mixing tank 2.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 9As shown, the discharge mechanism 7 includes a discharge pump 701 fixedly installed on the top of the base plate 1. The input end of the discharge pump 701 is fixedly connected to a discharge pipe 702. The end of the discharge pipe 702 away from the discharge pump 701 is connected to the interior of the mixing tank 2. A second solenoid valve 703 is installed on the discharge pipe 702. A quartz tube 801 is fixedly connected to the output end of the discharge pump 701. The discharge pump 701 provides stable power for conveying the mixed raw materials. The output flow rate can be adjusted according to the rhythm of subsequent orientation processing to ensure that the raw materials enter the quartz tube 801 at a uniform speed and avoid flow rate fluctuations affecting the orientation effect. The second solenoid valve 703 on the discharge pipe 702 is linked with the PLC controller 9 to precisely control the discharge timing. The discharge is started only after the raw materials are mixed to the standard to ensure the mixing quality. Moreover, the quartz tube 801 has good light transmittance and chemical stability, and does not affect the magnetic field control effect and raw material performance.

[0031] like Figure 7 , Figure 8 and Figure 9 As shown, the top of the mixing tank 2 is provided with a groove 10, and the bottom of the tank cover 3 is fixedly installed with a sealing ring 11. Two support plates 802 are fixedly connected to the top of the base plate 1. One end of the quartz tube 801 is fixedly connected to a conveying pipe 811. The groove 10 on the top of the mixing tank 2 and the sealing ring 11 at the bottom of the tank cover 3 are precisely matched to form a double sealing structure, which effectively prevents the leakage of raw materials or the entry of external impurities during the mixing process, and ensures the purity of the composite system. The conveying pipe 811 at one end of the quartz tube 801 can be directly connected to the feed end of the calender to realize the continuous conveying of raw materials after orientation treatment, which provides a guarantee for the continuous forming of orientation, calendering and cooling, and improves production efficiency.

[0032] The usage and working principle of this device are as follows: During the raw material replenishment stage, open the first solenoid valve 405 of the feed pipe 404 on the storage tank 401, and inject cellulose nanocrystals, phosphorescent molecules, and auxiliary raw materials into the three storage tanks 401 respectively. After injecting the appropriate raw materials, close the corresponding first solenoid valve 405. During the batching and mixing stage, the PLC controller 9 controls the opening of the first solenoid valve 405 on the corresponding extraction pipe 403 of the three storage tanks 401, and at the same time starts the metering pump 402 to pump each raw material into the mixing tank 2 according to the preset ratio. After the batching is completed, the first solenoid valve 405 and the metering pump 402 are closed. Then, the first servo motor 501 is started to drive the first stirring shaft 502 to drive the stirring paddle 507 to perform axial stirring. At the same time, the circular plate 503 revolves with the first stirring shaft 502. The second stirring shaft 504 rotates by meshing the spur gear 505 and the internal gear 506 to form radial and axial all-round stirring, covering the entire area of ​​the mixing tank 2, thoroughly breaking up the raw material agglomerates, and achieving molecular-level uniform dispersion of cellulose nanocrystals and phosphorescent molecules. During the orientation stage, the PLC controller 9 starts the third servo motor 810, drives the bidirectional threaded rod 804 to rotate, adjusts the distance between the two permanent magnets 807, and the magnetometer 809 provides real-time feedback of the magnetic field parameters until the preset magnetic field strength is reached. Then the third servo motor 810 stops, and the second solenoid valve 703 on the discharge pipe 702 is opened to start the discharge pump 701. The uniformly mixed raw material enters the quartz tube 801 at a constant speed under the action of stable power. Under the action of the directional magnetic field, the phosphorescent molecules complete the orientation and arrangement and are continuously transported to the conveying pipe 811. In the continuous forming and winding stage, by connecting to the subsequent forming equipment, the outlet of the conveying pipe 811 is aligned with the feed end of the calender. The calender and cooling roller group are started, and the calendering thickness and cooling temperature are set. The orientation-treated raw material is rolled into a film by the calender and then cooled and shaped by the cooling roller group to complete the processing (the use of a calender to roll into a film is an existing technology, and its specific results and working principle will not be described here, and it is not shown in the figure). During the equipment maintenance and cleaning phase, after processing is completed, the pick-and-place maintenance mechanism 6 is started. The second servo motor 607 drives the one-way threaded rod 602 to rotate, which drives the lifting plate 605 to rise along the fixed rod 603. The tank cover 3 rises with the connecting frame 606, which allows the inside of the mixing tank 2 and the stirring paddle 507 to be cleaned. After cleaning is completed, the second servo motor 607 is started to rotate in the opposite direction, the tank cover 3 is lowered and reset, the PLC controller 9 is turned off, the power is cut off, and the maintenance is completed.

The appropriate models are selected according to actual use.
