Technical Field
[0001] This utility model relates to the field of automated weighing device technology, and more specifically, to an automated weighing device for the production of negative electrode adhesive. Background Technology
[0002] In the field of negative electrode binder production, the handling and weighing of raw materials has a critical impact on product quality and production efficiency. During the production process of negative electrode binders, it is necessary to accurately weigh various raw materials to ensure the stability of product quality.
[0003] Traditional production methods suffer from numerous problems. In terms of raw material storage, the lack of effective stirring devices leads to sedimentation and stratification, affecting uniformity and stability, and consequently causing unstable quality and inconsistent performance of the produced negative electrode binder. In the weighing process, the absence of high-precision weighing equipment and intelligent control methods makes it difficult to accurately control the amount of raw materials added, resulting in significant errors and failing to meet the stringent requirements for high-precision weighing. Furthermore, manual operation accounts for a large proportion, leading to high labor intensity, low production efficiency, and difficulty in guaranteeing weighing accuracy due to human factors. This can easily cause fluctuations in product quality and lead to production delays and raw material waste due to human interference in the production process.
[0004] This invention can effectively improve the accuracy of weighing devices. Utility Model Content

[0013] A further preferred embodiment: the feed pipe is provided with multiple baffles arranged in an alternating manner and the baffles are inclined downwards.
[0014] Beneficial effects:
[0015] 1. By incorporating a weighing sensor, the weight of the raw material in the hopper is monitored in real time, and this crucial data is accurately transmitted to the controller. Thanks to its high sensitivity and precision, the controller can promptly and accurately grasp the weight changes of the raw material in the hopper. During the weighing process, this provides reliable data support to the controller, enabling it to precisely control the opening and closing of the solenoid valve based on the preset weight value. This precise control ensures the high accuracy of the raw material weight in each weighing, effectively reducing weighing errors. For the production of negative electrode adhesives, the accuracy of raw material weighing directly affects the stability and consistency of product quality. The weighing sensor ensures the accuracy of the amount of raw material added during production, laying a solid foundation for producing high-quality, stable negative electrode adhesives and greatly satisfying the stringent requirements for high-precision raw material weighing in production.
[0016] 2. Equipped with a flow regulating valve, when raw materials flow from the storage tank to the hopper via the conveying pipe, it is electrically connected to the controller and receives instructions from the controller. The controller intelligently sends an electrical signal to the flow regulating valve based on the real-time weight data transmitted by the weighing sensor and the preset weighing speed and accuracy requirements, thereby precisely controlling its opening. When approaching the target weighing value, the controller reduces the opening of the flow regulating valve, allowing the raw materials to flow slowly into the hopper. This fine adjustment function avoids over-conveying due to excessive raw material flow rate, greatly improving weighing accuracy. By effectively controlling the raw material conveying flow, it not only ensures the accuracy of each weighing but also further improves the stability of product quality. At the same time, it works in conjunction with the entire automated control system to optimize the production process, improve production efficiency, and reduce production delays and raw material waste caused by inaccurate weighing.
[0017] 3. The mixing units, located inside both the storage tank and the measuring hopper, play a crucial role in ensuring raw material quality. In the storage tank, a motor drives a rotating rod, and the mixing blades on the outer surface of the rod rotate at high speed, thoroughly mixing the temporarily stored raw materials. This effectively prevents sedimentation, stratification, and other adverse phenomena during storage, maintaining the uniformity and stability of the raw materials. The mixing units also play a role during the process of transporting the raw materials from the storage tank to the measuring hopper and within the measuring hopper, further ensuring the uniformity of the raw materials during the transport process. Stable and uniform raw materials are essential for the production of negative electrode adhesives, ensuring stable product quality and consistent performance. In addition, the bearings at the bottom of the rotating rod reduce friction and wear during rotation, extending the service life of the mixing units, reducing equipment maintenance costs, and ensuring long-term stable operation of the mixing units, providing strong support for continuous and efficient production.
[0018] 4. In summary, this automated weighing device for negative electrode adhesive production, equipped with a weighing sensor and a stirring assembly, ensures high-precision weighing of raw materials. The weighing sensor provides real-time, accurate weight monitoring to the controller, which precisely controls the solenoid valves, thus guaranteeing stable product quality. The flow regulating valve intelligently adjusts its opening based on weighing data and preset requirements, preventing excessive material delivery, improving weighing accuracy, optimizing the production process, and reducing delays and waste. The stirring assembly operates within the storage tank and measuring hopper, preventing material sedimentation and stratification, ensuring uniform and stable material distribution at each stage. Combined with bearings, it extends service life and reduces maintenance costs, comprehensively safeguarding the efficient and high-quality operation of negative electrode adhesive production.

Detailed Implementation
[0024] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.
[0025] Please see Figure 1-4 In this embodiment of the present invention, an automated weighing device for the production of negative electrode adhesive includes: a support 1, a storage tank 2 at the upper end of the support 1, a measuring hopper 3 suspended below the support 1, a conveyor belt 5 at the bottom of the support 1, a controller 6 installed on one side of the support 1, a conveying pipe 7 embedded at the bottom of the storage tank 2, and the other end of the conveying pipe 7 embedded inside the measuring hopper 3; both the storage tank 2 and the measuring hopper 3 are equipped with a stirring group 4; a feed pipe 201 is embedded at the upper end of the storage tank 2; the stirring group 4 includes a motor 401, a rotating rod 402, and a stirring blade 403; the rotating rod 402 is installed at the output end of the motor 401, and the stirring blade 403 is nested on the outer surface of the rotating rod 402; the measuring hopper 3 is connected to the support 1 through a weighing sensor 8; an electromagnetic valve is installed at the upper end of the inner wall of the conveying pipe 7; a discharge port 301 is provided at the bottom of the measuring hopper 3, and a discharge valve is installed at the discharge port 301; a bearing 404 is nested on the outer surface of the bottom of the rotating rod 402, and the bearing 404 is embedded in the bottom of the storage tank 2 and the measuring hopper 3 respectively;
[0026] The negative electrode adhesive raw material enters the storage tank 2 through the feed pipe 201 and is temporarily stored in the storage tank 2. The stirring group 4 in the storage tank 2 starts to work. The motor 401 drives the rotating rod 402 to rotate. The stirring blades 403 on the outer surface of the rotating rod 402 stir the raw material in the storage tank 2 to make the raw material uniformly mixed and prevent the raw material from settling or separating during storage, thus ensuring the uniformity and stability of the raw material. When it is necessary to weigh the raw material, the controller 6 controls the electromagnetic valve at the upper end of the inner wall of the conveying pipe 7 to open. The raw material in the storage tank 2 flows into the measuring hopper 3 under the action of gravity through the conveying pipe 7. The measuring hopper 3 is connected to the support 1 through the weighing sensor 8. The weighing sensor 8 monitors the weight of the raw material in the measuring hopper 3 in real time and transmits the weight signal to the controller 6. When the raw material in hopper 3 reaches the set weight value, controller 6 controls the solenoid valve to close, stopping the material conveying and completing one weighing process. After weighing, controller 6 controls the discharge valve at the discharge port 301 at the bottom of hopper 3 to open, and the raw material in hopper 3 falls through discharge port 301 onto the conveyor belt 5 below, which transports the raw material to the subsequent production process. After unloading, the discharge valve closes, preparing for the next weighing. While hopper 3 is unloading, the stirring group 4 in storage tank 2 continues to work, ensuring that the raw material in storage tank 2 is always in a uniformly mixed state, preparing for the next weighing. The entire device, controlled by controller 6, realizes automated feeding, weighing, unloading, and transportation processes, improving production efficiency and weighing efficiency. The weighing accuracy is ensured by real-time monitoring of the weight of the raw materials in the weighing hopper 3 via a weighing sensor 8, and precise control of the solenoid valve by a controller 6. This accurate control of the raw material weight for each weighing ensures weighing accuracy, reduces errors, and meets the requirements for raw material weighing accuracy in the production of negative electrode adhesives. Both the storage tank 2 and the weighing hopper 3 are equipped with stirring groups 4, which can fully stir the raw materials during storage and transportation, preventing sedimentation and stratification, ensuring the uniformity of the raw materials, and thus improving the product quality of the negative electrode adhesive. This device, through the controller 6, automates the processes of feeding, weighing, unloading, and transportation, reducing manual operation, lowering labor intensity, improving production efficiency, and minimizing human interference in the production process, thus ensuring... To ensure production stability and consistency, the measuring hopper 3 is connected to the support 1 via the weighing sensor 8, guaranteeing accurate weighing. Bearings 404 are nested on the bottom outer surface of the rotating rod 402, embedded in the storage box 2 and the bottom of the measuring hopper 3, effectively supporting the rotating rod 402, reducing friction and wear during rotation, and extending the service life of the mixing unit 4. The reasonable placement of the conveying pipe 7 and the discharge port 301 ensures smooth material delivery and discharge. The device is operated via the controller 6, with a simple and easy-to-understand interface, allowing operators to easily set weighing parameters and control the device's operation. Furthermore, the device's structure is relatively simple, with easy installation and disassembly of components, facilitating daily maintenance and repair, and reducing maintenance costs.
[0027] In this embodiment of the utility model, a conduit 302 is nested on the outer surface of the discharge port 301, a divider 501 is placed on the upper end of the conveyor belt 5, the conduit 302 is located on the upper end of the divider 501, and the conduit 302 is detachably threaded to the bottom of the measuring hopper 3; a flow regulating valve 701 is provided at one end of the conveying pipe 7 near the measuring hopper 3, and the flow regulating valve 701 is electrically connected to the controller 6; an observation window is provided on the outside of the storage box 2, and a shock-absorbing pad 101 is provided at the bottom of the bracket 1. The shock-absorbing pad 101 is made of rubber; multiple baffles 202 are provided inside the feed pipe 201, and the baffles 202 are staggered and inclined downwards;
[0028] When the discharge valve opens, the weighed material in the measuring hopper 3 flows out from the discharge port 301. Since a guide tube 302 is nested on the outer surface of the discharge port 301, and the guide tube 302 is located at the top of the distribution box 501, the material will flow into the distribution box 501 along the guide tube 302. The guide tube 302 is detachably threaded to the bottom of the measuring hopper 3, making it easy to remove the guide tube 302 from the measuring hopper 3 when cleaning, replacing, or performing equipment maintenance is required. The design of the guide tube 302 guides the material accurately into the distribution box 501, preventing the material from being mishandled during discharge. Spillage during the process causes waste and pollution to the production environment. The detachable threaded connection enhances the convenience of equipment maintenance, reducing maintenance difficulty and cost. At the same time, the divider 501 can classify and collect materials on the conveyor belt 5, facilitating the separate processing of different batches or types of raw materials and improving the orderliness of production management. A flow regulating valve 701 is installed at the end of the conveying pipe 7 near the measuring hopper 3, and the flow regulating valve 701 is electrically connected to the controller 6. During the process of raw materials flowing from the storage box 2 to the measuring hopper 3 through the conveying pipe 7, the flow regulating valve 701 is controlled. The controller 6 can send an electrical signal to the flow regulating valve 701 based on the real-time weight data transmitted by the weighing sensor 8 and the preset weighing speed and accuracy requirements, thereby controlling the opening of the flow regulating valve 701. When the set weighing weight is about to be reached, the controller 6 reduces the opening of the flow regulating valve 701, allowing the raw material to slowly flow into the measuring hopper 3, achieving accurate weighing. The setting of the flow regulating valve 701 can effectively control the conveying flow of the raw material. Together with the weighing sensor 8 and the controller 6, it can achieve precise adjustment of the speed at which the raw material flows into the measuring hopper 3. When approaching the target weighing value, the flow rate can be reduced, which can greatly improve the weighing accuracy and avoid over-conveying due to excessive raw material flow rate, further improving the stability of product quality. The observation window set on the outside of the storage box 2 allows the operator to directly observe the storage status of the raw material in the storage box 2, including the remaining amount of raw material, whether there are abnormal phenomena such as agglomeration or sedimentation. The existence of the observation window allows the operator to understand the status of the internal raw material without opening the storage box 2, which facilitates timely replenishment of raw materials and avoids production interruption due to insufficient raw materials.On the other hand, it can quickly detect abnormalities in raw materials so that corresponding measures can be taken, such as stirring and adjusting, and cleaning up lumps, to ensure the continuity of production and product quality. The bottom of the support 1 is equipped with a rubber shock-absorbing pad 101. During equipment operation, the operation of the motor 401, the stirring of raw materials by the stirring blades 403, and the flow of raw materials will all generate certain vibrations. The shock-absorbing pad 101 absorbs and buffers these vibrations through its own elastic deformation, reducing the transmission of vibration to the ground and the propagation of vibration inside the equipment. The shock-absorbing pad 101 can effectively reduce the vibration and noise generated during equipment operation, reduce the impact on the surrounding working environment, and at the same time, reduce the damage of vibration to the equipment's own parts, extend the service life of the equipment, and improve... To ensure the stability and reliability of the equipment operation, the feed pipe 201 is equipped with multiple staggered, downward-sloping baffles 202. When the raw material enters the storage tank 2 through the feed pipe 201, it impacts the baffles 202, changing the flow direction of the raw material. The raw material flows slowly into the storage tank 2 in an "S" shaped path, briefly stopping and dispersing on the baffles 202. The staggered baffles 202 buffer and disperse the raw material, preventing it from directly impacting the bottom of the storage tank 2 at high speed during feeding, reducing impact damage to the internal structure of the storage tank 2. Simultaneously, it ensures a more uniform distribution of the raw material upon entering the storage tank 2, facilitating more efficient and uniform mixing by the subsequent mixing unit 4, further improving the quality of the raw material mixture.
[0029] Working Principle: The negative electrode adhesive raw material enters the storage tank 2 through the feed pipe 201. The staggered and downward-sloping baffles 202 inside the feed pipe 201 cause the raw material to impact and change its flow direction, flowing in slowly in an "S" shape. The raw material briefly stops and disperses on the baffles 202, buffering and evenly distributing it, reducing impact on the bottom of the storage tank 2, which is beneficial for subsequent mixing. The raw material is temporarily stored in the storage tank 2. The mixing group 4 inside the tank is started. The motor 401 drives the rotating rod 402 to rotate, driving the mixing blades 403 to mix, ensuring uniform mixing of the raw material, preventing sedimentation and stratification, and ensuring the uniformity and stability of the raw material. The bearing 404 at the bottom of the rotating rod 402 is embedded in the bottom of the storage tank 2, supporting the rotating rod 402 and reducing friction and wear. When weighing is required, the controller 6 opens the solenoid valve at the upper end of the conveying pipe 7. The raw material enters the measuring hopper 3 by gravity through the conveying pipe 7. The measuring hopper 3 is connected to the bracket 1 through the weighing sensor 8. The sensor monitors the weight of the raw material in real time and transmits it to the controller 6. When the weight approaches the set value, the controller 6 adjusts the flow rate according to the weighing data and preset requirements. The regulating valve 701 sends an electrical signal to reduce its opening, allowing the raw material to flow in slowly and achieve accurate weighing. After reaching the set value, the controller 6 closes the solenoid valve, completing one weighing cycle. After weighing, the controller 6 opens the discharge valve of the discharge port 301 at the bottom of the measuring hopper 3, and the raw material flows out through the discharge port 301. Because the discharge port 301 is nested with a guide tube 302 and located above the distribution box 501, the raw material flows into the distribution box 501 along the guide tube 302. The guide tube 302 and the bottom of the measuring hopper 3 are detachably threaded for easy maintenance. The distribution box 501 collects the materials on the conveyor belt 5 in categories, which is conducive to subsequent batch and category processing. During the unloading of the measuring hopper 3, the stirring group 4 in the storage box 2 continues to work to maintain the uniform mixing of the raw materials and prepare for the next weighing. The entire device is automatically controlled by the controller 6. The operation interface is simple and easy to set parameters and operate. The rubber shock-absorbing pad 101 at the bottom of the support 1 absorbs the vibration generated by the operation of the motor 401, stirring, and the flow of raw materials, reducing the impact on the environment and extending the service life of the equipment.
