Description

Technical Field

[0001] The invention relates to the field of quantum dot diffusion plate production, and more specifically to a raw material extrusion molding device for producing quantum dot diffusion plates. Background Art

[0002] The quantum dot diffuser plate is an innovative product that integrates quantum dot technology into the diffuser plate. It is made of highly stable quantum dots co-extruded with PMMA or PS plastic masterbatch, diffusion particles, antioxidants, etc. It is widely used in lighting, display and other fields. Extruders are often used for molding in its production process. During the continuous production process of the extruder, various stains, residues and carbon deposits will gradually accumulate inside due to the high-temperature melting of the material, the friction between the screw and the barrel, and the influence of environmental factors. These pollutants will not only affect the production efficiency of the extruder, but may also have a negative impact on the quality of the diffuser plate, such as surface defects and uneven color. Therefore, regular and thorough cleaning of the inside of the extruder is an important measure to ensure the production quality of the diffuser plate and the stable operation of the equipment.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) This scheme is provided with an extrusion mechanism and a cleaning mechanism. When the hot melt material in the extrusion cavity is extruded by the extrusion mechanism and the production of the quantum dot diffusion plate is completed, some hot melt material will remain in the extrusion cavity and some dirt will remain on the impeller. If not cleaned in time, it will seriously affect the subsequent processing of the quantum dot diffusion plate and affect the quality of the finished product. Therefore, after the production of the quantum dot diffusion plate is completed, a solid cleaning agent can be added to the extrusion cavity to soak the parts in the extrusion cavity. At the same time, by starting the drive motor and using the transmission component to make the drive rod drive the scraper to rotate, the scraper is used to scrape and clean the stubborn dirt remaining on the surface of the impeller.

[0019] (2) By providing a cleaning mechanism, in the process of using a solid cleaning agent and a scraper to clean the extrusion cavity of the extrusion die box, the scraper will be worn to a certain extent due to long-term use, making the subsequent cleaning effect poor. Therefore, the extrusion die box can be opened regularly, and the support rod can be rotated to remove it from the threaded barrel, and the fixedly connected vertical plate, spring telescopic rod, scraper and other parts can be removed from the driving rod, so that it is convenient for the staff to replace the new scraper, ensuring that the cleaning effect of the replaced scraper is better.

[0020] (3) By providing a cleaning mechanism, since the temperature in the extrusion chamber is uneven during the production of quantum dot diffusion plates using an extrusion mechanism, a small amount of raw materials will not be completely melted. Therefore, during the transmission process using an impeller, an interception plate can be used to intercept the unmelted raw materials, thereby ensuring that the quality of the produced quantum dot diffusion plates meets qualified standards. The intercepted unmelted raw materials are cleaned by the cleaning plate on the surface of the interception plate during the process of rotating the driving rod using the transmission component, thereby further ensuring that the subsequent production of quantum dot diffusion plates proceeds normally.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 8 , a raw material extrusion molding equipment for the production of quantum dot diffusion plates, including an extrusion mold box 1, one side of the extrusion mold box 1 is a heating zone, and the other side is a cooling zone, the extrusion mold box 1 includes a first accommodating frame 11 and a second accommodating frame 12, the first accommodating frame 11 and the second accommodating frame 12 jointly form an extrusion cavity, the first accommodating frame 11 and the second accommodating frame 12 are respectively connected by bolts with a first sealing plate 13 and a second sealing plate 14 on both sides, the extrusion cavity is provided with an extrusion mechanism 6 for extruding the raw material of the diffusion plate after hot melting, the extrusion mechanism 6 includes a first rotating rod 62 and a second rotating rod 63 arranged in the extrusion cavity, the outer circumferential surfaces of the first rotating rod 62 and the second rotating rod 63 are fixedly connected with uniformly distributed impellers 64, one end of the first rotating rod 62 is provided with a driving motor 61, and the first rotating rod 62 and the second rotating rod 63 are jointly provided with a coupling 65 for transmission at one end close to the driving motor 61;

[0039] A cleaning mechanism 9 for cleaning residual dirt on the surface of the impeller 64 is provided in the middle of the extrusion cavity; wherein the cleaning mechanism 9 includes a driving rod 91 rotatably connected to the middle of the extrusion cavity, and the outer cylindrical surface of the driving rod 91 is provided with evenly distributed vertical plates 97, and spring telescopic rods 98 are provided on both sides of the top of the vertical plates 97, and one end of the spring telescopic rod 98 is fixedly connected to a scraper 99 for cleaning residual dirt on the surface of the impeller 64.

[0040] like Figure 1 , Figure 2 , Figure 3 As shown, a machine head 4 is provided on one side of the outer surface of the second sealing plate 14, and a conveying channel 3 is fixedly connected between the machine head 4 and the second sealing plate 14. The cleaning mechanism 9 also includes a first support frame 92 fixedly connected to the outer side of the first sealing plate 13, and a second support frame 912 is fixedly connected to one side of the conveying channel 3 close to the inside of the second sealing plate 14. The first support frame 92 and the second support frame 912 are connected to a driving rod 91 for rotation together. A transmission assembly 93 is provided at one end of the driving rod 91 close to the first support frame 92; and the first rotating rod 62 rotates the driving rod 91 through the transmission assembly 93.

[0041] When the hot-melt material in the extrusion cavity is extruded by the extrusion mechanism 6 and the production of the quantum dot diffusion plate is completed, some hot-melt material will remain in the extrusion cavity and some dirt will remain on the impeller 64. If it is not cleaned in time, it will seriously affect the subsequent processing of the quantum dot diffusion plate and affect the quality of the finished product. Therefore, after the production of the quantum dot diffusion plate is completed, when the extrusion cavity of the extrusion mold box 1 needs to be cleaned, a solid cleaning agent can be added to the extrusion cavity to soak the parts in the extrusion cavity. At the same time, the drive motor 61 can be started, and the coupling 65 can be used to rotate the first rotating rod 62 and the second rotating rod 63, and the impeller 64 is stirred in the extrusion cavity filled with the solid cleaning agent, so that the dirt on the surface that is easy to fall off is thrown off, and the stubborn dirt that is difficult to fall off can be removed during the rotation of the first rotating rod 62. In the process, the driving rod 91 is rotated by using the transmission assembly 93 (this transmission assembly 93 includes a first fixed wheel fixedly connected to the first rotating rod 62 and a second fixed wheel of the driving rod 91, and a belt fixedly mounted on the first fixed wheel and the second fixed wheel), so that the vertical plate 97 drives the scraper 99 to rotate synchronously, so that the scraper 99 scrapes and cleans the stubborn dirt remaining on the surface of the impeller 64, so that in combination with a fixed cleaning agent, the impeller 64 and the residual raw materials in the extrusion cavity can be cleaned without disassembling the machine, and the cleaning effect is better. In the cleaning process, the impeller 64 rotates, squeezing the scraper 99, and the spring telescopic rod 98 is used to prevent the scraper 99 from being damaged, and the scraper 99 can fit the impeller 64 as closely as possible to scrape and clean it.

[0042] like Figure 3 , Figure 4 As shown, the driving rod 91 passes through the first sealing plate 13 and is fixedly connected to evenly distributed fixing blocks 94, the upper surfaces of the fixing blocks 94 are fixedly connected to threaded tubes 95, the internal threads of the threaded tubes 95 are connected to support rods 96, and the tops of the support rods 96 are fixedly connected to vertical plates 97.

[0043] In the process of using solid cleaning agent and scraper 99 to clean the extrusion cavity of the extrusion mold box 1, the scraper 99 will produce certain wear due to long-term use, making the subsequent cleaning effect poor. Therefore, the extrusion mold box 1 can be opened regularly, and the first sealing plate 13 and the second sealing plate 14 are first removed from the first receiving frame 11 and the second receiving frame 12, and then the first receiving frame 11 and the second receiving frame 12 are disassembled. At this time, the support rod 96 can be rotated to remove it from the threaded barrel 95, and the fixedly connected vertical plate 97, spring telescopic rod 98, scraper 99 and other parts can be removed from the driving rod 91, so as to facilitate the staff to replace the new scraper 99 and ensure that the cleaning effect of the replaced scraper 99 is better.

[0044] like Figure 2 , Figure 5 As shown, the second sealing plate 14 is fixedly connected to the inside with an intercepting plate 15, one end of the driving rod 91 passes through the second sealing plate 14 and is fixedly connected to a second fixing sleeve 910, and both sides of the outer circular surface of the second fixing sleeve 910 are fixedly connected with cleaning plates 911 for cleaning the intercepting plate 15.

[0045] Since the temperature in the extrusion cavity is uneven during the production of quantum dot diffusion plates using the extrusion mechanism 6, a small amount of raw materials will not be completely melted. Therefore, during the transmission process using the impeller 64, the interception plate 15 can be used to intercept the unmelted raw materials to ensure that the quality of the produced quantum dot diffusion plates meets the qualified standards. When the transmission component 93 is used to rotate the drive rod 91, the drive rod 91 can drive the second fixed sleeve 910 to rotate synchronously, so that the cleaning plate 911 cleans the residual dirt on the surface of the interception plate 15, further ensuring the normal production of subsequent quantum dot diffusion plates.

[0046] like Figure 1 , Figure 2 As shown, the first accommodating frame 11 is connected to the second accommodating frame 12 by bolts, a placement plate 5 is fixedly connected to one side of the outer surface of the first sealing plate 13, a driving motor 61 is fixedly connected to one end of the placement plate 5; and an output end of the driving motor 61 is fixedly connected to the first rotating rod 62.

[0047] like Figure 1 , Figure 5As shown, a heating box 2 is provided on one side of the first accommodating rack 11 and the second accommodating rack 12 close to the driving motor 61, a feed discharge port 16 and a filling port 17 are provided on the top of the first accommodating rack 11 and the second accommodating rack 12, a discharge port 18 is provided on the bottom of the first accommodating rack 11 and the second accommodating rack 12, a mixing mechanism 7 and a feeding barrel 8 are provided at the positions of the feed discharge port 16 and the filling port 17 respectively, and support seats are fixedly connected to both sides of the bottom of the first accommodating rack 11 and the second accommodating rack 12.

[0048] like Figure 1 , Figure 6 , Figure 7 As shown, the mixing mechanism 7 includes a mixing barrel 71 threadedly connected to the top of the discharge port 16, a first support plate 72 is fixedly connected to the inner top of the mixing barrel 71, a servo motor 73 is fixedly connected to the middle of the upper surface of the first support plate 72, a screw rod 74 is fixedly connected to the output end of the servo motor 73, the screw rod 74 passes through the first support plate 72 and is fixedly connected to a first fixed sleeve 75, and stirring rods 76 are fixedly connected to both sides of the outer cylindrical surface of the first fixed sleeve 75.

[0049] When producing quantum dot diffusion plates, the neutralizing material can be poured into the feeding barrel 8, and the materials required for the production of quantum dot diffusion plates can be directly poured into the mixing barrel 71 after drying. However, if the materials poured into the mixing barrel 71 are not fully mixed before hot melting, it is easy to cause uneven mixing of the materials after hot melting, affecting the quality of the finished product of the quantum dot diffusion plate. Therefore, after the materials are poured into the mixing barrel 71, the servo motor 73 can be started to make the screw rod 74 drive the first fixed sleeve 75 to rotate, and make the stirring rod 76 rotate synchronously, and use the stirring rod 76 to fully mix the various materials in the mixing barrel 71 to ensure that when the mixed materials pass through the discharge port 16 into the extrusion cavity of the extrusion mold box 1, the finished product effect after hot melting is better.

[0050] like Figure 7 As shown, a material discharge assembly 77 is provided at the inner bottom of the mixing barrel 71, and the material discharge assembly 77 includes a fixed plate 775 fixedly connected to the middle of the inner wall of the mixing barrel 71, and the mixing barrel 71 is fixedly connected to the limit frame 774 through the fixed plate 775. The middle of the outer cylindrical surface of the screw rod 74 is threadedly connected to the threaded sleeve 771, and both sides of the outer cylindrical surface of the threaded sleeve 771 are provided with L-shaped connecting plates 772 slidably connected to the inside of the limit frame 774, and the bottom of the L-shaped connecting plate 772 is fixedly connected to a blocking block 773.

[0051] During the raw material mixing process, the raw materials directly enter the extrusion cavity of the extrusion mold box 1 from the feed port 16, and the hot-melt raw materials easily enter the mixing barrel 71 from the feed port 16 during the extrusion process, causing the feed port 16 to be blocked, affecting the subsequent normal feeding process. Therefore, during the extrusion molding process, the servo motor 73 can be started to make the screw rod 74 drive the threaded sleeve 771 to rotate, and the limit frame 774 can be used to make the L-shaped connecting plate 772 drive the blocking block 773 to move downward to block the feed port 16, thereby cleaning the hot-melt raw materials on the inner wall of the feed port 16, which can effectively avoid the feed port 16 from being blocked.

[0052] like Figure 1 , Figure 6 , Figure 8 As shown, a recovery mechanism 10 for recovering waste liquid is provided below the discharge port 18, and the recovery mechanism 10 includes a recovery barrel 101 provided below the discharge port 18, and a barrel cover 102 is threadedly connected to the top of the recovery barrel 101, and a valve is provided inside the barrel cover 102, and the middle part of the barrel cover 102 is a cylindrical protrusion; and the cylindrical protrusion is threadedly connected to the discharge port 18.

[0053] like Figure 8 As shown, a pad is provided in the middle of the inner wall of the recovery barrel 101, an adsorption plate 103 is placed above the pad, a connecting rod 104 is fixedly connected in the middle of the adsorption plate 103, and a filter plate 105 is fixedly connected in the middle of the outer circumferential surface of the connecting rod 104.

[0054] Since a certain amount of waste liquid and impurities may be generated in the process of cleaning the extrusion cavity of the extrusion die box 1 with a solid cleaning agent, the valve of the recovery barrel 101 can be opened at this time to allow the extrusion cavity to enter the recovery barrel 101 from the discharge port 18 through the barrel cover 102, and the incoming waste liquid is subjected to a preliminary filtration treatment by the filter plate 105, and then subjected to adsorption treatment by the adsorption plate 103, so that the harmful substances are cleaned up, thereby reducing the subsequent waste liquid treatment work and avoiding the discharged waste liquid from polluting the environment.

[0055] Instructions for use: When producing quantum dot diffusion plates, first pour the neutralized material into the feeding barrel 8, and after the materials required for the production of quantum dot diffusion plates are dried, pour them into the mixing barrel 71, start the servo motor 73, so that the screw rod 74 drives the first fixed sleeve 75 to rotate, so that the stirring rod 76 fully mixes the various materials in the mixing barrel 71, and the mixed materials enter the extrusion cavity of the extrusion die box 1 through the discharge port 16. At this time, the heating box 2 can be started to perform a hot-melt operation on the mixed material entering the extrusion cavity, and then the discharge port 16 is blocked by the blocking block 773 through the discharge component 77, and then the drive motor 61 is started, and the coupling 65 is used to rotate the first rotating rod 62 and the second rotating rod 63, so that the impeller 64 rotates synchronously, so that the hot-melted material first passes through the heating zone and then enters the cooling zone, and then enters the conveying channel 3 from the intercepting plate 15 to the head 4, and is extruded at the die mouth of the head 4, thereby completing the quantum dot diffusion plate. The extrusion molding operation of the diffusion plate is performed. When the production of the quantum dot diffusion plate is completed and the extrusion cavity needs to be cleaned, the solid cleaning agent can be poured from the feeding barrel 8 into the extrusion cavity to soak the internal parts. At the same time, the drive motor 61 can be started again, and the transmission assembly 93 can be used to rotate the drive rod 91, so that the vertical plate 97 drives the scraper 99 to rotate synchronously, so that the scraper 99 scrapes and cleans the stubborn dirt remaining on the surface of the impeller 64. In the process of using the solid cleaning agent to clean the extrusion cavity of the extrusion die box 1, the waste liquid and impurities generated can be opened by opening the valve of the recovery barrel 101, so that the extrusion cavity enters the recovery barrel 101 from the discharge port 18 through the barrel cover 102, and the filter plate 105 is used to perform preliminary filtering treatment on the incoming waste liquid, and then after adsorption treatment by the adsorption plate 103, the treated waste liquid and impurities are uniformly collected in the recovery barrel 101, which can effectively avoid the direct discharge of waste liquid to pollute the environment.

[0056] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
