Description

Technical Field

[0001] The present invention relates to the technical field of QD material processing, and specifically to an anti-caking mixing and feeding device for QD masterbatch batching. Background Art

[0002] In the field of QD (quantum dot) material processing, especially in the batching and production process of QD masterbatch, many technical challenges are faced. QD masterbatch needs to be added to the QD board during the production process to achieve specific colors and optical properties. However, there are many problems with traditional addition and mixing methods, which seriously affect the product quality and production efficiency. For example:

[0003] QD masterbatch has a certain viscosity at room temperature, and this viscosity causes many problems during the production process. For example, during the stirring process, QD masterbatch is prone to caking and cannot be evenly dispersed in other ingredients. This caking phenomenon not only affects the accuracy of the formula but also causes problems such as color dot deviation and uneven brightness and darkness of the picture.

[0004] In the production of QD masterbatch, in addition to the viscosity problem of QD masterbatch itself, it also needs to be mixed with other ingredients. The mixed materials are generally powdery ingredients such as dispersants, oxidants, weathering agents, light stabilizers, and lubricating dispersants. However, due to the relatively small volume and mass of the powdery ingredients, they are prone to accumulate at the bottom of the mixing chamber during the mixing process, resulting in uneven mixing. During the subsequent screw feeding process, the powder ingredients are prone to separate from the QD masterbatch, further exacerbating the problem of uneven mixing. This uneven mixing not only affects the optical properties of the QD board but also may cause quality fluctuations during the production process. These problems severely limit the development of QD material processing technology, and there is an urgent need for an anti-caking mixing and feeding device that can effectively solve the above problems. Summary of the Invention

[0005] (1) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the present invention provides an anti-caking mixing and feeding device for QD masterbatch batching. By using the masterbatch injection part to perform a flat-laying feeding process on the injected masterbatch, it can effectively prevent the caking phenomenon of the masterbatch due to its own viscosity, which affects the uniformity of subsequent mixing. By using the ingredient injection part to inject the powder ingredients into the masterbatch injection part, it not only facilitates better contact between the masterbatch and the powder ingredients to form a powder coating operation, improving the mixing uniformity, but also can effectively reduce the viscosity of the masterbatch raw material itself, thereby preventing the masterbatch from caking and affecting the mixing uniformity problem.

[0022] (III) Beneficial effects

[0023] Compared with the prior art, the present invention provides an anti-caking mixing and discharging device for QD masterbatch ingredients, which has the following beneficial effects:

[0024] 1. In the present invention, the injected masterbatch is discharged in a flattened manner through the masterbatch injection part, which can effectively prevent the caking phenomenon of the masterbatch due to its own viscosity, affecting the uniformity of subsequent mixing; the powder ingredients are injected into the masterbatch injection part through the ingredient injection part, which not only facilitates the better contact between the masterbatch and the powder ingredients to form a powder coating operation, improving the mixing uniformity, but also can effectively reduce the viscosity of the masterbatch raw material itself, thus preventing the caking of the masterbatch and affecting the mixing uniformity problem.

The powder is ejected through a plurality of nozzles on the conical cover, enabling the recycled powder to come into contact with the masterbatch again, thereby improving the mixing effect of the ingredients. It not only has the function of multiple mixing but also effectively prevents the problem that when the masterbatch after mixing is being transported, the powder ingredients on its outer surface are likely to fall off and the movement rates of the separated powder ingredients and the masterbatch are unequal, resulting in uneven mixing of the masterbatch after discharging.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Embodiment 1:

[0044] Referring to the attached Figures 1 to 10 , an anti-caking mixing and discharging device for QD masterbatch ingredients, including a mounting base 1. A housing 2 with an open top and a feeding cylinder 3 are fixedly connected to the top of the mounting base 1. The bottom of the housing 2 is communicated with the inside of the feeding cylinder 3. A feeding screw 4 is rotatably installed inside the feeding cylinder 3;

[0045] Through the setting of the housing 2, it is used to store the QD masterbatch mixture. Through the feeding screw 4 and the feeding cylinder 3, the QD masterbatch mixture is fed by the online loss-in-weight scale screw;

[0046] The top of the housing 2 is detachably installed with a cover plate 5. A masterbatch injection part 6 is arranged on the cover plate 5, and an ingredient injection part 7 is arranged on the housing 2;

[0047] Through the setting of the masterbatch injection part 6, it is used to inject the masterbatch raw material into the inside of the housing 2. Through the ingredient injection part 7, it is used to inject the powder ingredient into the inside of the housing 2. The ingredient mixing process is carried out through the mixing mechanism built inside the housing 2;

[0048] The masterbatch injection part 6 is used to inject the masterbatch into the inside of the housing 2, and the ingredient injection part 7 is used to inject the powder ingredient into the inside of the housing 2, so that the masterbatch and the powder ingredient are synchronously mixed and enter the inside of the housing 2;

[0049] By using the masterbatch injection part 6 to process the injected masterbatch with a flat feeding method, it can effectively prevent the caking phenomenon of the masterbatch due to its own viscosity, which affects the uniformity of subsequent mixing; by using the ingredient injection part 7 to inject the powder ingredients into the masterbatch injection part 6, it not only facilitates better contact between the masterbatch and the powder ingredients to form a powder coating operation, improving the mixing uniformity, but also can effectively reduce the viscosity of the masterbatch raw material itself, thus preventing the masterbatch from caking and affecting its mixing uniformity problem.

[0050] It solves the problem that in the existing masterbatch feeding equipment, when mixing and feeding the masterbatch, generally the masterbatch raw material and powder ingredients are directly placed into the mixing chamber for processing. Since the volume and mass of the powder ingredients are much lower than those of the masterbatch, during processing, the powder ingredients are prone to accumulate at the bottom of the mixing chamber, which not only affects the uniformity of subsequent mixing, but also in the subsequent screw feeding, the powder ingredients in the front and back parts of the mixture are prone to uneven problems.

[0051] Refer to the appendix Figure 1 、 Figure 2 、 Figure 5 and Figure 8 As shown in FIGS.

[0052] By arranging a mixing rack 8 inside the mixing chamber, it can stir the masterbatch mixture during the feeding process, not only improving the mixing uniformity of the mixture, but also improving the orderliness of injection.

[0053] The rotating part 9 includes a motor and a gear transmission box, which are used to synchronously drive the mixing rack 8 and the feeding screw 4 to rotate, forming a synchronous driving operation for mixing and feeding.

[0054] One end of the feeding cylinder 3 is fixedly communicated with a collecting cylinder 10.

[0055] Through the setting of the collecting cylinder 10, it is used to collect and feed the masterbatch mixture for feeding and discharging treatment.

[0056] Refer to the appendix Figures 3 to 7 As shown in FIG.

[0057] Through the setting of the injection nozzle 62, the masterbatch in the external masterbatch storage area is discharged into the interior of the housing 2. The U-shaped hopper 61 with an inclined shape is used to guide the masterbatch, improving the orderliness of its injection and preventing the problem that the masterbatch in the feeding process agglomerates due to its own viscosity.

[0058] It should be noted here that when injecting the masterbatch through the injection nozzle 62, a quantitative and uniform injection method is adopted to prevent excessive one-time injection of the masterbatch, resulting in the accumulation of the masterbatch at the corner of the U-shaped hopper 61.

[0059] The batching injection member 7 includes a first powder delivery pump 72 fixed to the housing 2. The powder outlet of the first powder delivery pump 72 extends into the interior of the housing 2 through a powder outlet pipe 74, and a metering valve is provided on the powder outlet pipe 74.

[0060] Through the setting of the first powder delivery pump 72, the prepared powder batching from the outside is extracted and discharged into the interior of the housing 2 through the powder outlet pipe 74 to contact the masterbatch. The mixing rack 8 inside the housing 2 is used for uniform mixing. Through the setting of the metering valve, the input amount of the powder is controlled to improve the accuracy of the batching.

[0061] Refer to the appendix Figures 5 to 7 The batching injection member 7 further includes a batching cylinder 71 fixed to one side of the housing 2. A mixing member 73 for mixing several powdery batchings inside the batching cylinder 71 is provided on the batching cylinder 71. The suction port of the first powder delivery pump 72 is communicated with the interior of the batching cylinder 71 through a suction pipe.

[0062] By providing the mixing member 73 on the batching cylinder 71, it is convenient to uniformly mix multiple powder batchings through the mixing member 73 to form a premixing operation, so as to facilitate the subsequent uniform mixing of all batchings and the masterbatch.

[0063] Refer to the appendix Figure 6 and Figure 7 Referring to the appendix

[0064] A partition cavity 63 is formed at the bottom of the U-shaped hopper 61. A plurality of powder through-holes 64 communicating with the interior of the partition cavity 63 are formed in the inner bottom of the U-shaped hopper 61. A connecting pipe 65 communicating with the interior of the partition cavity 63 is fixedly connected to the bottom of the U-shaped hopper 61.

[0065] The powder outlet of the powder outlet pipe 74 is arranged upward, and a connecting sleeve for inserting and connecting the connecting pipe 65 is fixedly connected to the powder outlet end of the powder outlet pipe 74;

[0066] One end of the powder outlet pipe 74 is connected with a connecting sleeve, which facilitates the orderly insertion of the connecting pipe 65 into the powder outlet pipe 74 when the cover plate 5 is installed, so that the masterbatch injection part 6 and the ingredient injection part 7 are interconnected to form the subsequent powder coating work.

[0067] Refer to the appendix Figure 6 and Figure 7 , an L-shaped pressing plate 66 is arranged inside the U-shaped hopper 61. The L-shaped pressing plate 66 is used for flattening the masterbatch that is discharged downward and obliquely through the U-shaped hopper 61. The distance between the L-shaped pressing plate 66 and the inner bottom of the U-shaped hopper 61 is greater than the diameter of the masterbatch and less than or equal to twice the diameter of the masterbatch;

[0068] Through the setting of the L-shaped pressing plate 66, it is used to control the thickness of the masterbatch guided by the inclined U-shaped hopper 61. It can not only prevent the caking phenomenon of the masterbatch due to its own viscosity, which affects the uniformity of subsequent mixing, but also facilitate the better contact and wrapping of the masterbatch with the powder ingredients, thereby improving the uniformity of its mixing;

[0069] An auxiliary plate is elastically installed at the bottom of the L-shaped pressing plate 66. The elastically installed auxiliary plate is used to elastically press the masterbatch at the bottom of the L-shaped pressing plate 66 to press and disperse the masterbatch that is adhered together;

[0070] A vibrator is arranged at the bottom of the U-shaped hopper 61, and the vibrator is used to vibrate the masterbatch guided through the U-shaped hopper 61, so that the masterbatch during the feeding process is fully dispersed, and it cooperates with the powder sprayed from the powder through-hole 64 for powder coating of the masterbatch.

[0071] Refer to the appendix Figure 1 , Figure 2 and Figures 8 to 10 , a processing component 11 for re-mixing the separated ingredients and masterbatch is arranged inside the collecting cylinder 10.

[0072] Through the setting of the processing component 11, it is used to receive the powder ingredients separated during the screw feeding of the masterbatch mixture, and re-discharge them into the collecting cylinder 10 for re-mixing with the masterbatch fed during the feeding. It has the function of multiple mixing processes, avoiding the problem of uneven transportation during the transportation and feeding of the masterbatch mixture, which affects the ratio.

[0073] Embodiment 2: The difference from Embodiment 1 is that;

[0074] Refer to the appendix Figure 6 and Figure 7, on both sides of the inner wall of the U-shaped hopper 61, guiding slot openings 67 parallel to the U-shaped hopper 61 are provided. One end of the L-shaped pressing plate 66 is fixedly connected with a movable shaft 68, and both ends of the movable shaft 68 respectively extend into the interiors of the two guiding slot openings 67; on the top of the cover plate 5, an electric telescopic rod 69 is fixedly connected. The telescopic end of the electric telescopic rod 69 extends to the bottom of the cover plate 5, and an articulated frame 610 is articulated between the telescopic end of the electric telescopic rod 69 and the L-shaped pressing plate 66;

[0075] The electric telescopic rod 69 is connected to an external power supply and a control switch, and is used to drive the L-shaped pressing plate 66 to move up and down. Through the up and down movement of the L-shaped pressing plate 66, the masterbatch discharged from the U-shaped hopper 61 can be laid flat, so that the masterbatch can better contact the powder ingredients sprayed through the powder through-port 64, forming the masterbatch mixing work;

[0076] Since both ends of the movable shaft 68 on the L-shaped pressing plate 66 are respectively located in the two guiding slot openings 67, when the L-shaped pressing plate 66 moves up and down, it can move along the inclined trajectory of the U-shaped hopper 61. This not only realizes the laying flat work of the masterbatch, but also facilitates the laid flat masterbatch to tightly roll along the inclined trajectory of the U-shaped hopper 61, thereby increasing its mixing efficiency with the powder ingredients.

[0077] Embodiment 3: Different from Embodiment 1;

[0078] Referring to the attached Figures 8 to 10 , the processing component 11 includes a collection cylinder 111 fixed to the output end of the feeding cylinder 3 and a second powder conveying pump 112 fixed to the mounting base 1. A plurality of strip-shaped separation openings 113 communicating with the interior of the collection cylinder 111 are provided on the inner surface of the feeding cylinder 3. The second powder conveying pump 112 is used to quantitatively convey the powdery ingredients inside the collection cylinder 111 into the interior of the collection cylinder 10;

[0079] By providing a plurality of strip-shaped separation openings 113 between the collection cylinder 111 and the feeding cylinder 3, it is convenient to separately separate the separated powdery ingredients during the spiral conveying process of the mixed masterbatch material. The collected powder ingredients are contacted with the masterbatch during the export process again in equal amounts by the second powder conveying pump 112, thereby improving the effect of subsequent QD plate extrusion manufacturing;

[0080] It solves the problem that when the mixed masterbatch and powder ingredients are fed through the feeding screw 4, the powder is prone to separate from the masterbatch. Due to the unequal volume and mass of the powder and the masterbatch, when the two separated products are conveyed and fed, different movement effects are likely to occur, resulting in uneven mixing of the masterbatch in the subsequent feeding;

[0081] Inside the collecting cylinder 10, a through pipe 114 is fixedly connected. The bottom end of the through pipe 114 is rotatably connected to a conical cover 115. Inside the conical cover 115, a conical cavity communicating with the inside of the through pipe 114 is provided. At the top of the conical cover 115, a plurality of spray nozzles are provided. The powder outlet of the second powder delivery pump 112 is communicated with the inside of the through pipe 114 through a delivery pipe.

[0082] Through the setting of the second powder delivery pump 112, it is used to extract the powder ingredients collected inside the collecting cylinder 111, and discharge them into the inside of the conical cover 115 through the through pipe 114, and spray them out through the plurality of spray nozzles on the conical cover 115. In this way, the recovered powder can contact the masterbatch again, thereby improving the mixing effect of its ingredients. It not only has the function of mixing multiple times, but also effectively prevents the powder ingredients on the outer surface of the masterbatch from falling off easily during transportation, and the movement speeds of the separated powder ingredients and the masterbatch are not equal, resulting in uneven mixing of the masterbatch after feeding.

[0083] Inside the through pipe 114, a blade frame 116 is rotatably connected, and the blade frame 116 is fixedly connected to the conical cover 115.

[0084] By rotatably connecting the blade frame 116 in the through pipe 114, when the powder gas is transported through the through pipe 114, the driving force can drive the blade frame 116 to rotate. Since the blade frame 116 is fixedly connected to the conical cover 115, the conical cover 115 rotates synchronously. Through the rotation of the conical cover 115, the masterbatch above can be disturbed, thereby improving the contact effect between the masterbatch and the powder ingredients, and further improving the uniformity of the mixed feeding. Moreover, it has the function of self-driving.

[0085] It should be noted that the term "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Without further limitations, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0086] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
