Description

Technical Field

[0001] This utility model relates to the field of raw material proportioning technology for tempered glass film processing, and in particular to a raw material proportioning device for tempered glass film processing. Background Technology

[0002] The production process of tempered glass film typically requires the mixing and proportioning of various raw materials, such as adhesives, solvents, and additives, according to a set ratio to ensure uniform coating thickness, good light transmittance, and stable adhesion. Existing raw material proportioning devices generally consist of multiple raw material tanks, metering units, and mixing chambers, and mainly achieve the weighing and mixing of raw materials through automatic feeding and stirring.

[0003] In actual use, raw materials such as adhesives, solvents or powders in the raw material tank often show obvious sedimentation or stratification when left to stand for a long time. For example, the high molecular weight components in the adhesive tend to gradually accumulate at the bottom of the tank, while the low viscosity solvent tends to float on the upper layer. Powder raw materials will gradually sink and form local accumulation under the action of gravity. As a result, when the feeding is started, the concentration of the first part flowing out is lower and the concentration of the subsequent part flowing out is higher, which causes the proportion of raw materials entering the mixing tank to deviate from the set value. Utility Model Content

[0004] Based on this, it is necessary to provide a raw material proportioning device for tempered film processing to address the problem that, in actual use, raw materials such as adhesives, solvents, or powders in the raw material tank are prone to sedimentation or stratification after being left to stand for a long time. For example, the high molecular weight components of the adhesive may deposit at the bottom of the tank, the low viscosity solvent may float on the top, and the powder may sink and accumulate under the action of gravity. This results in uneven concentration before and after feeding, causing the proportion of raw materials entering the mixing tank to deviate from the set value.

[0005] A raw material proportioning device for tempered glass film processing includes a mixing tank, a plurality of raw material tanks disposed on the top of the mixing tank, and a proportioning and mixing mechanism disposed on one side of the plurality of raw material tanks to prevent the raw materials inside the raw material tanks from stratifying or becoming uneven. The proportioning and mixing mechanism includes a mounting bracket fixedly installed on the top of the mixing tank, a homogenizing component disposed on the outside of the plurality of raw material tanks, and a separation component disposed on the outside of the raw material tanks.

[0006] The homogenizing component includes a drive pump fixedly installed on the outside of the raw material tank. The suction end of the drive pump is fixedly installed with a suction pipe, the other end of the suction pipe is fixedly connected to the bottom of the raw material tank, and the output end of the drive pump is fixedly connected with an output pipe. The other end of the output pipe is fixedly connected to the surface of the raw material tank, and the output pipe is located at the top of the suction pipe.

[0007] The bottom of the raw material tank is cone-shaped, and a viscosity sensor is fixedly installed at the bottom of the raw material tank.

[0008] The detection end of the viscosity sensor extends into the interior of the raw material tank, and a detection rod is fixedly connected to the detection end of the viscosity sensor. The detection rod is located on one side of the material discharge end of the raw material tank.

[0009] An electric valve is fixedly connected to the discharge end of the raw material tank, and the electric valve is connected to the inside of the raw material tank.

[0010] A fixing frame is provided on the outside of the raw material tank. The fixing frames on the outside of the raw material tank are fixedly connected to the mounting bracket. An electromagnetic motor is fixedly installed on the outside of the fixing frame. Multiple magnetic blocks are fixedly installed inside the fixing frame. Multiple docking slots are opened on the outside of the raw material tank. The multiple docking slots are respectively engaged with the multiple magnetic blocks.

[0011] The separation assembly includes a feed pipe that is sealed and snapped onto the other end of the electric valve, the other end of which is connected to the interior of the mixing tank.

[0012] A sealing ring is provided on the outside of the feed pipe, and multiple sealing rings are fixedly connected to the top of the mixing tank. A sealing groove is provided on the outside of the feed pipe, and the feed pipe is sealed and snapped into the sealing ring through the sealing groove.

[0013] Beneficial effects

[0014] 1. By setting up a uniform component, the raw materials can be stirred at regular intervals during the storage stage to avoid sedimentation or stratification caused by standing, ensuring the accuracy of the proportion entering the mixing tank, improving the stability of the ratio and the consistency of the finished product.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined Figures 1-5 This invention describes a raw material proportioning device for tempered glass film processing.

[0026] In one embodiment, a raw material proportioning device for tempered glass film processing includes: a mixing tank 100, with a plurality of raw material tanks 200 disposed on the top of the mixing tank 100; a proportioning and mixing mechanism 300, which is disposed on one side of the plurality of raw material tanks 200 to prevent the raw materials inside the raw material tanks 200 from stratifying or becoming uneven; wherein, the proportioning and mixing mechanism 300 includes a mounting bracket 310 fixedly installed on the top of the mixing tank 100, a homogenizing component 320 disposed on the outside of the plurality of raw material tanks 200, and a separating component 330 disposed on the outside of the raw material tanks 200.

[0027] In this embodiment, the uniform component 320 installed on the outside of the raw material tank 200 can be used to stir the raw materials at regular intervals during the storage stage, so that the raw materials are always kept in a uniform state inside the tank. This effectively avoids the problems of sedimentation or stratification caused by long-term standing, thereby ensuring that the proportion of raw materials entering the mixing tank 100 is more accurate, improving the stability of the ratio and the consistency of the final tempered film. The separation component 330 installed on the outside of the raw material tank 200 can quickly replace the pipeline or cavity when the production process needs to switch to different formulas, which significantly shortens the time required for material replacement and cleaning, and avoids cross-contamination between different raw materials.

[0028] It should be noted that the mixing tank 100 for receiving and mixing different raw materials, the multiple raw material tanks 200 for storing various raw materials, and the metering unit and conveying pipelines located between the mixing tank 100 and the raw material tanks 200, these basic components work together to quantitatively feed and proportion the raw materials. The homogenizing component 320 is installed on the outside of the raw material tank 200. Its main function is to perform timed stirring during the raw material settling stage to prevent sedimentation or stratification. It does not change the feeding method between the raw material tank 200 and the mixing tank 100, and therefore will not affect the normal conveying and proportioning accuracy of the raw materials. The separating component 330 is also located on the outside of the raw material tank 200. It is used to quickly replace the pipelines or cavities when switching between different formulas. It is limited to assisting in material replacement and cleaning and does not participate in the raw material weighing and feeding process. Therefore, it will not interfere with the conventional metering and mixing functions of the proportioning device.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, the uniform assembly 320 includes a drive pump 321 fixedly installed on the outside of the raw material tank 200. The suction end of the drive pump 321 is fixedly installed with a suction pipe 322. The other end of the suction pipe 322 is fixedly connected to the bottom of the raw material tank 200. The output end of the drive pump 321 is fixedly connected with an output pipe 323. The other end of the output pipe 323 is fixedly connected to the surface of the raw material tank 200. The output pipe 323 is located at the top of the suction pipe 322.

[0030] In this embodiment, the uniform component 320 draws the raw material from the bottom of the raw material tank 200 through the suction pipe 322 via the driving pump 321, and then returns it to the upper or middle part of the raw material tank 200 through the output pipe 323, thereby forming a bottom-up circulating flow path inside the tank. This effectively prevents the deposition of polymer adhesives or powder particles at the bottom of the tank during the raw material settling period, while also avoiding the concentration of low-viscosity solvents in the upper layer, ensuring that the raw material inside the tank is always in a relatively uniform state. Compared with the traditional method that relies on mechanical stirring paddles, this method achieves low-energy consumption and low-shear circulating uniformization without direct contact with the raw material. It does not damage the performance of the raw material system and can significantly improve the stability of the raw material concentration entering the mixing tank 100, thereby improving the mixing accuracy and the consistency and pass rate of the tempered film finished product.

[0031] It should be noted that the drive pump 321 can be a conventional low-power liquid circulation pump, such as a miniature diaphragm pump, gear pump, or magnetic drive pump. The drive pump 321 can achieve stable suction with low energy consumption. The suction end of the drive pump 321 is connected to the bottom of the raw material tank 200 through the suction pipe 322.

[0032] To avoid excessive shearing or increased energy consumption in the raw material system, the drive pump 321 can operate intermittently, for example, starting and running for about 5 minutes every 30 minutes to create periodic, gentle circulation. This operating mode effectively prevents sedimentation at the bottom of the tank or accumulation of low-viscosity solvent on the upper layer of the tank, while maintaining the uniformity of the raw materials without continuously consuming energy or adversely affecting the structure of the raw materials.

[0033] The bottom of the raw material tank 200 is set in a conical shape, and a viscosity sensor 325 is fixedly installed at the bottom of the raw material tank 200.

[0034] In this embodiment, the bottom of the raw material tank 200 is designed with a conical structure, allowing the raw material inside the tank to naturally converge to the bottom outlet under gravity, reducing raw material retention and dead zone deposition, which is beneficial for subsequent extraction and circulation. By installing a viscosity sensor 325 at the bottom of the raw material tank 200, the viscosity changes of the raw material inside the tank can be detected in real time, reflecting the concentration fluctuations caused by sedimentation or stratification, thereby providing accurate reference data for proportioning control.

[0035] The detection end of the viscosity sensor 325 extends into the interior of the raw material tank 200. The detection end of the viscosity sensor 325 is fixedly connected to a detection rod 326, which is located on one side of the material discharge end of the raw material tank 200.

[0036] In this embodiment, the detection rod 326 extends into the inside of the raw material tank 200 and is located near the discharge end, so that the flow state of the raw material can be detected in real time before it actually flows out. The setting of the detection rod 326 allows the viscosity sensor 325 to penetrate into the effective liquid layer area of ​​the raw material tank 200, avoiding only detecting the surface layer and ignoring the viscosity difference caused by the sedimentation of the raw material at the bottom.

[0037] An electric valve 324 is fixedly connected to the discharge end of the raw material tank 200, and the electric valve 324 is connected to the inside of the raw material tank 200.

[0038] In this embodiment, the electric valve 324 is connected to the inside of the raw material tank 200 and can automatically open and close the raw material feeding process under the command of the control component. Through the precise control of the electric valve 324, not only can the material be fed in a quantitative manner according to the set ratio, but it can also be closed in time when abnormal viscosity or flow deviation of the raw material is detected, so as to avoid inaccurate proportioning due to raw material sedimentation, stratification or sudden blockage.

[0039] A fixing frame 327 is provided on the outside of the raw material tank 200. The fixing frames 327 on the outside of the multiple raw material tanks 200 are fixedly connected to the mounting bracket 310. An electromagnetic motor 328 is fixedly installed on the outside of the fixing frame 327. Multiple magnetic blocks 329 are fixedly installed inside the fixing frame 327. Multiple docking slots 3210 are opened on the outside of the raw material tank 200. The multiple docking slots 3210 are respectively engaged with the multiple magnetic blocks 329.

[0040] In this embodiment, after power is applied, a magnetic force is applied to the internal magnetic block 329, thereby reliably engaging the magnetic block 329 with the mating groove 3210 on the outside of the raw material tank 200, achieving rapid locking of the raw material tank 200 and the fixing frame 327. Simultaneously, the magnetic block 329 forms a continuous magnetic attraction force on the outer wall of the raw material tank 200, further enhancing the fixing strength. This combination of electromagnetic attraction and mechanical engagement not only ensures that the raw material tank 200 does not loosen or shift due to vibration or liquid impact during operation, but also greatly improves the assembly and disassembly efficiency of the raw material tank 200, facilitating quick replacement or maintenance.

[0041] It should be noted that the electromagnetic actuator 328 can employ a conventional electromagnetic adsorption mechanism, such as an electromagnet, a permanent magnet electromagnetic composite core, or a small electromagnetic actuator. Its coil is fixedly mounted on the outside of the fixed frame 327. When energized, it generates a magnetic field inside the fixed frame 327, thereby exerting an attractive force on the magnetic block 329. The attraction force of the electromagnetic actuator 328 can be adjusted by controlling the current or voltage to meet the locking requirements of raw material tanks 200 of different sizes. The electromagnetic actuator 328 can be electrically connected to the control unit and operates in two modes: intermittent energization and continuous energization. During loading and unloading, pulsed energization is used for quick engagement or release; during operation, continuous energization is used to maintain stable magnetic adsorption.

[0042] like Figure 2 , Figure 3 and Figure 5 As shown, the separation assembly 330 includes a feed pipe 331 that is sealed and snapped onto the other end of the electric valve 324, and the other end of the feed pipe 331 is connected to the interior of the mixing tank 100.

[0043] In this embodiment, the feed pipe 331 adopts a detachable snap-fit ​​structure. When switching between different formulas, the operator only needs to quickly replace the corresponding feed pipe 331 to complete the pipeline switching and residue isolation, thus avoiding cross-contamination between different raw materials.

[0044] A sealing ring 332 is provided on the outside of the feed pipe 331. Multiple sealing rings 332 are fixedly connected to the top of the mixing tank 100. A sealing groove 333 is provided on the outside of the feed pipe 331. The feed pipe 331 is sealed and engaged with the sealing ring 332 through the sealing groove 333.

[0045] In this embodiment, multiple sealing rings 332 are fixed to the top of the mixing tank 100, enabling the feed pipe 331 to achieve a reliable sealing connection during installation. This prevents raw material leakage or air ingress during the feeding process, ensuring the stability and purity of the conveying process. By adopting a snap-fit ​​fixing method, compared with traditional threaded or adhesive methods, it can achieve quick disassembly and assembly while maintaining high sealing performance. This facilitates the replacement of the feed pipe 331 when switching between different formulas, reduces residual cleaning steps, and avoids cross-contamination.

[0046] Working Principle: First, the required raw materials are added to multiple raw material tanks 200. Each raw material tank 200 is mounted on the mounting frame 310 via a fixing frame 327, and is quickly locked in place by an electromagnetic motor 328 and a magnetic block 329 with a docking groove 3210, thus ensuring the stability of the raw material tank 200 during operation. After the device is started, the homogenizing component 320 enters the working state, driving the pump 321 to draw the raw material from the bottom of the raw material tank 200 through the suction pipe 322, and then return it to the upper part of the raw material tank 200 through the output pipe 323, thereby forming a circulating flow inside the tank, avoiding sedimentation or stratification caused by prolonged static placement of the raw material, and ensuring that the material inside the tank is always in a homogenous state. During the feeding process, the viscosity sensor 325 and the detection rod 326 detect the viscosity of the raw material at the bottom of the raw material tank 200 in real time. When the detected value meets the set range, the control unit issues a command to open the electric valve 324, and the raw material enters the feeding pipe 331 of the separation component 330 through the electric valve 324. The feed pipe 331 is sealed and engaged with multiple sealing rings 332 fixed to the top of the mixing tank 100 via a sealing groove 333, ensuring that the raw materials do not leak or become contaminated during the feeding process and are stably delivered into the mixing tank 100. When switching between different formulas, the operator can directly disassemble the feed pipe 331 and replace it with a new pipeline assembly. The snap-fit ​​sealing structure allows for quick replacement, avoiding cross-contamination caused by incomplete cleaning. The electromagnetic motor 328 can be pulsed during this process to quickly release and relock the raw material tank 200, facilitating tank replacement or maintenance by the operator.

[0047] It should be noted that the drive pump, viscosity sensor, and solenoid mentioned above are all devices with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the drive pump, viscosity sensor, and solenoid can be powered by the built-in power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
