[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope protected by the present application.

[0035] In the description of the present application, it should be understood that the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or indicating the number of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "a plurality" means two or more, unless otherwise specifically defined.

[0036] Please refer to Figures 1 to 3, the implementation of this application provides an automatic premixing device for materials used in glass covers. This device can integrate multiple functional modules to achieve automatic premixing of materials, thereby improving production efficiency and reducing the complexity of manual operations. This embodiment is particularly applicable to large-scale glass cover production lines. By optimizing the processes of material transportation, weighing, and mixing, the quality and production consistency of glass covers are improved. Specifically, the automatic premixing device for materials used in glass covers includes a feed bin 1, a feeding pipe 2, a weighing and receiving platform 3, a stirring and mixing mechanism 4, a storage bin 5, a metering feeding mechanism 6, and a weighing and receiving bin. Among them, the feed bin 1 is provided with a first feed inlet 11 and a first discharge outlet 12. The feeding pipe 2 is connected to the first discharge outlet 12. The weighing and receiving platform 3 is located at the end of the feeding pipe 2 away from the first discharge outlet 12 and is used to receive the materials from the feeding pipe 2. The stirring and mixing mechanism 4 is arranged on one side of the weighing and receiving platform 3 and is provided with a material conveying port 411 and a feeding port 412. The storage bin 5 is arranged below the stirring and mixing mechanism 4 and is provided with a second feed inlet 51 and a second discharge outlet 52. The second feed inlet 51 is hermetically connected to the feeding port 412. The metering feeding mechanism 6 is connected to the lower part of the storage bin 5 and is provided with a third feed inlet 611 and a third discharge outlet 612. The third feed inlet 611 is connected to the second discharge outlet 52 and is used for quantitatively conveying the mixed material. The weighing and receiving bin 7 is connected to the third discharge outlet 612 and is used to receive and weigh the mixed material from the metering feeding mechanism 6.

[0037] The technical solution provided by this application mainly forms a one-line system for material mixing, storage, and metered discharging by the joint cooperation of the feed bin 1, the weighing and receiving platform 3, the stirring and mixing mechanism 4, the storage bin 5, the metering feeding mechanism 6, and the weighing and receiving bin 7. While ensuring that the materials are fully mixed and the proportion weight meets the standards, it can also reduce the labor intensity of workers and improve the mixing efficiency. Specifically, first, the feed bin 1 is used for feeding, and the materials to be mixed are conveyed to the weighing and receiving platform 3 through the feeding pipe 2, and the materials to be mixed are accurately weighed to ensure the correct ratio of the subsequent mixed materials. Secondly, the stirring and mixing mechanism 4 is used to fully mix the weighed materials. Then, the storage bin 5 is used to store the fully mixed mixed materials for subsequent ready use. When materials are needed, the metering feeding mechanism 6 is used to quantitatively send the mixed materials in the storage bin 5 to the weighing and receiving bin 7, and it can convey an accurate amount of mixed materials according to the needs. Moreover, the weighing and receiving bin 7 is used to further weigh the mixed materials conveyed by the metering feeding mechanism 6 to ensure that the weight of the mixed materials meets the standards, realizing the uniform mixing, metered mixing, metered storage, and metered discharging of the mixed materials. And the whole process is a one-line operation with a high degree of automation, which is beneficial to improving the operation efficiency and reducing the labor intensity of workers.

[0038] It should be noted that the feed bin 1, as the starting point of the entire premixing process, is provided with a first feed inlet 11 and a first discharge outlet 12. Various raw materials in glass production are added to the feed bin 1 through the feed inlet. The funnel-shaped design of the feed bin 1 ensures smooth falling of the materials. To avoid accumulation or retention of materials in the feed bin 1, the inner wall of the feed bin 1 is made of stainless steel, which not only has good corrosion resistance but also can effectively reduce the generation of static electricity, ensuring the smooth outflow of materials. In addition, it can also avoid using iron containers, which may cause iron filings to mix into the materials and have an adverse impact on subsequent glass production.

[0039] The feed pipe 2 is connected to the first discharge outlet 12 of the feed bin 1 and is responsible for transporting the materials falling from the feed bin 1 to the next stage. The design of the feed pipe 2 takes into account the fluidity and friction of the materials, and the inner wall is also made of stainless steel, enhancing the stability of the transportation process. A regulating valve 21 is provided in the feed pipe 2. By adjusting the opening degree of the regulating valve 21, the flow rate of the materials can be accurately controlled to ensure a stable material supply to the downstream weighing and receiving platform 3.

[0040] The weighing and receiving platform 3 is located at the end of the feed pipe 2 and receives the materials from the feed pipe 2. The bottom of the platform is equipped with a high-precision electronic scale, which can monitor and record the weight data of the materials in real time. The design of the weighing and receiving platform 3 fully considers the characteristics of different materials. By adjusting the height and angle of the platform, it can adapt to materials with different volumes and densities to ensure the accuracy of weighing.

[0041] The stirring and mixing mechanism 4 is the core part of this embodiment and is responsible for uniformly mixing different types of materials. This mechanism includes a mixing bin 41, a main drive motor 42, a gearbox 43, a main drive shaft 44, a first stirring roller 45, and a second stirring roller 46.

[0042] The material inlet 411 of the mixing bin 41 is connected to the weighing and receiving platform 3, and the weighed materials are fed into the mixing bin 41 by gravity or mechanical transportation. A main drive motor 42 is provided at the top of the mixing bin 41. The motor drives the main drive shaft 44 to rotate through a gear set, and then drives the first and second stirring rollers 46 to fully mix the materials.

[0043] The designs of the first stirring roller 45 and the second stirring roller 46 take into account the mixing requirements of different materials. The first stirring roller 45 has a larger spiral angle and a longer shaft body, which can initially mix larger particle materials; the second stirring roller 46 is more suitable for further homogenization of smaller particles or powders.

[0044] The mixed material enters the storage bin 5 through the feeding port 412 of the stirring and mixing mechanism 4. The storage bin 5 adopts a funnel-shaped structure to ensure the smooth discharge of the material. The design of the storage bin 5 can prevent the mixed material from stratifying or segregating during storage. The second feeding port 51 is hermetically connected to the feeding port 412 of the stirring and mixing mechanism 4 to ensure that the material will not be contaminated by the outside world after mixing.

[0045] The metering feeding mechanism 6 is arranged below the storage bin 5 and includes a feeding pipe 61, a feeding motor 62 and a screw rod 63. The third feeding port 611 of the feeding pipe 61 is connected to the second discharging port 52 of the storage bin 5. The screw rod 63 is driven by the feeding motor 62 to convey the mixed material in the storage bin 5 to the weighing and receiving bin 7 as required.

[0046] The design of the screw rod 63 takes into account the physical properties of the mixed material. By controlling the rotation speed of the motor, quantitative output of the mixed material can be achieved, ensuring that the weight of the mixed material conveyed each time is consistent, thus guaranteeing the stability of the subsequent glass production process.

[0047] The weighing and receiving bin 7 is connected to the third discharging port 612 of the metering feeding mechanism 6. A weighing scale is provided in the receiving bin for accurately weighing the conveyed mixed material again. The weighing scale is installed at the bottom of the receiving bin, and the weight of the mixed material is monitored in real time through a sensor. The design of the weighing and receiving bin 7 ensures that the weight of the mixed material meets the set standard before entering the next process, thus effectively improving the production qualification rate of the glass cover plate.

[0048] In some embodiments, please refer to Figure 2, the stirring and mixing mechanism 4 includes a mixing bin 41, a main drive motor 42, a gearbox 43, a main drive shaft 44, a first stirring roller 45 and a second stirring roller 46. The mixing bin 41 is the core component of the stirring and mixing mechanism 4 and is used to accommodate and mix various raw materials. The mixing bin 41 is designed as a vertical cylindrical structure or a funnel shape with a smooth inner wall to avoid residue and accumulation of materials during the mixing process. A feeding port 411 and a material delivery port 412 are provided at the top of the mixing bin 41. The feeding port 411 is connected to the weighing and receiving platform 3 for receiving the weighed materials, and the material delivery port 412 is connected to the storage bin 5 for conveying the mixed materials to the next process. The main drive motor 42 is installed at the top of the mixing bin 41 and is the power source of the entire stirring and mixing mechanism 4. The output end of the motor is engaged with the gear set in the gearbox 43 through an output gear, transmitting the power to the main drive shaft 44, thereby driving the rotation of the stirring rollers. The main drive motor 42 is selected as a high-power and low-noise motor, which can operate continuously and stably under high load conditions to ensure the full mixing of materials. The gearbox 43 is provided at the top of the mixing bin 41 and contains a set of precision gears inside. The main drive motor 42 is engaged with the gear set in the gearbox 43 through an output gear, transmitting the rotational motion to the main drive shaft 44. The design of the gearbox 43 takes into account the matching of the reduction ratio and torque to ensure that the stirring rollers work at an appropriate speed and torque. The gears required inside the gearbox 43 are selected according to the actual situation. The main function of the gears is to transmit the rotational output of the main drive motor 42 to the stirring rollers, thereby driving the stirring rollers to rotate and realizing the mixing of materials. The main drive shaft 44 passes through the inside of the mixing bin 41 and is fixedly connected to the gear set. Through the rotation of the main drive shaft 44, the first stirring roller 45 and the second stirring roller 46 can rotate synchronously to stir and mix the materials. The first stirring roller 45 and the second stirring roller 46 are respectively located at both ends of the main drive shaft 44 and are both fixedly connected to the main drive shaft 44. The first stirring roller 45 is connected with a first sub-drive motor 451 and a first spiral stirring shaft 452, and the second stirring roller 46 is connected with a second sub-drive motor 461 and a second spiral stirring shaft 462. The design of the first spiral stirring shaft 452 focuses on handling larger particles or heavier materials. The angle and spacing of its spiral blades are larger, which can preliminarily mix the materials evenly in a short time. The second spiral stirring shaft 462 focuses on further fine mixing of the mixed materials. Its blade design is more delicate and suitable for handling lighter or smaller particle materials to ensure the uniformity of the final mixture.

[0049] In practical applications, the stirring and mixing mechanism 4 can handle a variety of different glass raw materials, such as silica sand, quartz sand, soda ash, etc. These raw materials first enter the weighing and receiving platform 3 through the feeding bin 1, and then enter the mixing bin 41 in sequence. The two groups of stirring rollers in the mixing bin 41 rotate at an appropriate speed under the combined action of the main drive motor 42 and the sub-drive motors, fully mixing different materials.

[0050] The dual functions of the first stirring roller 45 and the second stirring roller 46 ensure that materials with different particle sizes and densities can be evenly mixed, avoiding the problem of uneven mixing, thereby improving the quality of the glass cover plate. Through the efficient transmission design of the main drive motor 42 and the gearbox 43, the stirring and mixing mechanism 4 can complete the mixing of a large amount of materials in a short time, improving the production efficiency. The design of the mixing bin 41 avoids the residue and waste of materials during the stirring process. The spiral design of the stirring roller reduces the adhesion of materials inside the equipment, thereby reducing material loss. The stirring and mixing mechanism 4 can adapt to different types and specifications of glass raw materials by adjusting the motor speed and the stirring shaft design, and has high versatility and flexibility. The precise design of the main drive motor 42 and the gearbox 43 ensures the long-term stable operation of the equipment and reduces the risk of equipment failure. At the same time, the application of stainless steel material improves the durability and corrosion resistance of the device, ensuring the safety of the production process.

[0051] Furthermore, the first stirring roller 45 includes a first sub-drive motor 451 and a first spiral stirring shaft 452. The first sub-drive motor 451 is connected to one end of the main drive shaft 44, and the output end of the first sub-drive motor 451 is connected to the first spiral stirring shaft 452. The second stirring roller 46 includes a second sub-drive motor 461 and a second spiral stirring shaft 462. The second sub-drive motor 461 is connected to the end of the main drive shaft 44 away from the first sub-drive motor 451, and the output end of the second sub-drive motor 461 is connected to the second spiral stirring shaft 462. The first stirring roller 45 is driven by the first sub-drive motor 451, and the output end of the sub-drive motor is connected to the first spiral stirring shaft 452. In order to meet the preliminary mixing requirements of larger particle materials, the length of the first spiral stirring shaft 452 is designed to be relatively long, covering most of the area inside the mixing bin 41. The spacing and angle of the spiral blades are precisely calculated, and can quickly and evenly disperse the large particle materials throughout the mixing bin 41 in a short time. The second stirring roller 46 is driven by the other end of the main drive shaft 44, and the design of the spiral stirring shaft is relatively short, mainly covering the lower part of the mixing bin 41. The blade design of the second spiral stirring shaft 462 is relatively fine, suitable for processing fine particle or powdery materials, such as soda ash or other auxiliary components. These materials are further mixed with the materials mixed by the first stirring roller 45 through the rotation of the second spiral stirring shaft 462 to form a more uniform mixture.

[0052] In actual operation, the first stirring roller 45 and the second stirring roller 46 rotate synchronously. Since the first spiral stirring shaft 452 is relatively long and covers the upper region of the mixing bin 41, it ensures the uniform distribution of large-particle materials in the initial stage. At the same time, the second spiral stirring shaft 462 further mixes the already dispersed materials in the lower region, especially dealing with those lighter and finer particles, ensuring the uniformity of the materials in the entire mixing bin 41 in the vertical direction. Through the synchronous operation of the two stirring shafts, the entire mixing process becomes more efficient. It can not only quickly mix different types of materials but also avoid the layering phenomenon caused by different specific gravities of the materials. The synchronous operation of the two spiral stirring shafts effectively prevents the layering and accumulation of materials during the mixing process. Materials with different properties can be evenly distributed in the vertical direction, thus ensuring the overall uniformity of the mixed materials. The synchronously operating stirring rollers enable all the materials in the mixing bin 41 to be processed within the same time period, avoiding the time delay caused by staged mixing and greatly improving the mixing efficiency. Due to the synchronous operation of the first stirring roller 45 and the second stirring roller 46, the mixing process is more efficient, reducing unnecessary repeated mixing steps and thus lowering the energy consumption. By improving the uniformity of the mixed materials, the finally produced glass cover plate has been significantly improved in terms of physical properties and appearance quality, reducing quality defects such as bubbles and streaks caused by uneven mixing.

[0053] In some embodiments, see Figure 3, The quantitative feeding mechanism 6 mainly consists of a feeding pipe 61, a feeding motor 62, and a screw rod 63. These three parts work together to achieve the quantitative feeding of the mixed material. The feeding pipe 61 is the main channel of the quantitative feeding mechanism 6. One end of it is connected to the second discharge port 52 of the storage bin 5, and the other end is connected to the weighing and receiving bin 7. The inner wall of the feeding pipe 61 is smooth and made of stainless steel material, with excellent corrosion resistance and wear resistance, suitable for long-term conveying of various mixed materials in glass production. The feeding motor 62 is installed at one end of the feeding pipe 61 and drives the movement of the material in the feeding pipe 61 by controlling the rotation of the screw rod 63. The power and speed of this motor are precisely designed to ensure high-precision quantitative control during the conveying process. The speed of the motor can be adjusted according to the actual production requirements to adapt to the conveying speed requirements of different materials. The screw rod 63 is located inside the feeding pipe 61 and is connected to the output end of the feeding motor 62. The main function of the screw rod 63 is to push the material from the storage bin 5 to the weighing and receiving bin 7 by rotation. The blades of the screw rod 63 are designed in a spiral shape, and the angle and pitch of the blades are optimized according to the physical properties of the material to ensure that the material does not get blocked or flow back during the conveying process. In actual operation, the mixed material enters the quantitative feeding mechanism 6 from the second discharge port 52 of the storage bin 5 through the feeding pipe 61. After the feeding motor 62 is started, the screw rod 63 starts to rotate, causing the mixed material located inside the feeding pipe 61 to be squeezed by the blades of the screw rod 63. The screw rod 63 rotates with the motor. During the rotation process, the spiral structure can gradually push the mixed material out of the feeding pipe 61 and push the mixed material along the feeding pipe 61 to the weighing and receiving bin 7. The rotation speed and conveying volume of the screw rod 63 can be precisely adjusted through the control system of the feeding motor 62 to ensure that the amount of mixed material conveyed each time is consistent. Specifically, the operator can set the weight of the mixed material conveyed each time according to the production requirements. After the feeding motor 62 is started, the screw rod 63 pushes the mixed material to the weighing and receiving bin 7 at a preset speed. The weighing scale in the weighing and receiving bin 7 monitors the material weight in real time. When the set value is reached, the control system will automatically stop the operation of the feeding motor 62, thus completing a quantitative feeding process.

[0054] In the actual application of a glass cover plate production line, accurate weight of the mixed material is required for each batch of production. Suppose a certain production requires 200 kilograms of mixed material. The operator can preset this weight value in the control system. The feeding motor 62 of the quantitative feeding mechanism 6 will start and rotate the screw rod 63 according to the preset weight value, quantitatively conveying the mixed material from the storage bin 5 to the weighing and receiving bin 7. During the conveying process, the weighing scale will monitor the material weight in the weighing and receiving bin 7 in real time. When the material in the weighing and receiving bin 7 reaches 200 kilograms, the control system will send a stop signal, the feeding motor 62 will stop running, and the screw rod 63 will stop rotating, thus ensuring that the weight of the mixed material conveyed each time is accurately consistent.

[0055] The coordinated operation of the feeding motor 62 and the screw rod 63 can accurately control the weight of the mixed material conveyed each time, avoiding the errors that may occur in traditional manual weighing, and ensuring the consistency of each batch of products in the production process of the glass cover plate. The automated operation of the quantitative feeding mechanism 6 greatly reduces manual intervention, shortens the time for material conveying and weighing, and improves the overall operation efficiency of the production line. By accurately controlling the weight of the mixed material conveyed each time, the problems of excessive conveying and waste of materials are avoided, and the production cost is reduced. The design of the screw rod 63 can adapt to materials with different particle sizes and physical properties. Whether it is granular material or powdered material, it can be evenly and stably conveyed through the screw rod 63, with strong adaptability. Since the quantitative feeding mechanism 6 can ensure the accurate proportion of the mixed material, the finally produced glass cover plate is more uniform in composition, reducing the quality defects caused by inaccurate proportioning of the mixed material.

[0056] In some embodiments, the feeding bin 1, the feeding pipe 2, the storage bin 5, and the weighing receiving bin 7 are all transparent, which is beneficial for the staff to observe the situation of material conveying, mixing, and storage at all times.
