[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4This utility model discloses an automatic weighing and feeding device for the preparation of polyaluminum chloride, comprising: a mounting bracket 1 and auxiliary components. Linear motors 10 are fixedly connected to both the left and right sides of the inner wall of the mounting bracket 1. The linear motors 10 are stably supported by the mounting bracket 1, providing a lateral power source for subsequent components. A movable seat 11 is fixedly connected to the output end of the linear motors 10. Driven by the linear motors 10, the movable seat 11 can move linearly along the inner wall of the mounting bracket 1, thereby driving the connecting plate 12 connected to it to move synchronously. The connecting plate 12 is fixedly connected to the side wall of the movable seat 11, serving as an intermediate connecting component, transmitting the movement of the movable seat 11 to the lifting sliding groove 13 opened on its side wall and the fine-tuning hydraulic pump 14 below. The connecting plate 12 has two lifting sliding grooves 13 on its side wall. These grooves provide track constraints for the lifting movement of the sliding plate 18, ensuring stable vertical movement. A fine-tuning hydraulic pump 14 is fixedly connected to the lower surface of the connecting plate 12. The pump's output extension and retraction precisely control the position of the adjusting contact plate 15, allowing for fine-tuning of the height of the material conveying plate 19. The adjusting contact plate 15 is fixedly connected to the output of the fine-tuning hydraulic pump 14. Driven by the pump, the adjusting contact plate 15 moves up and down, transmitting force to the sliding plate 18 via the contact spring 17, thereby adjusting the height of the material conveying plate 19. The upper surface of the adjusting contact plate 15 abuts against a spring. Spring 17 acts as a buffer and force transmitter between the adjusting contact plate 15 and the sliding plate 18, making pressure changes smoother and preventing damage to the equipment from rigid impacts. The upper surface of spring 17 abuts against the sliding plate 18. Under the action of spring 17, the sliding plate 18 can move up and down along the lifting sliding groove 13, thereby driving the material conveying plate 19 fixedly connected to it to achieve height adjustment. The upper surface of the sliding plate 18 abuts against a pressure sensor 16, which monitors the pressure changes transmitted by the sliding plate 18 in real time, converts the pressure signal into an electrical signal, and feeds it back to the controller 2 for precise control of the fine-tuning hydraulic pump 14. The material conveying plate 19 is fixedly connected to the side wall of the sliding plate 18, and the material conveying plate 19 is connected to the sliding plate 18 via the sliding plate 18. Connecting plates 12 are connected and their height is adjusted by sliding plates 18. This allows for the placement of containers holding polyaluminum chloride. A weighing plate 5 is located on the lower surface of the material conveying plate 19, supporting the weight of the material conveying plate 19, the container above it, and the materials, providing accurate weight data for the weighing device 3. Contact grooves 20 are provided on both the left and right sides of the upper surface of the weighing plate 5. These grooves provide tracks for the rollers 21, ensuring smoother relative movement between the material conveying plate 19 and the weighing plate 5 and reducing frictional resistance. Several rollers 21 are rolled along the inner surface of the contact grooves 20, evenly transferring the weight of the material conveying plate 19 to the weighing plate 5.Simultaneously, the material conveying plate 19 is allowed a certain amount of displacement space in the horizontal direction. Each roller 21 has a mounting base 22 rotatably connected to both its left and right sides. The mounting base 22 provides rotational support for the roller 21, ensuring that the roller 21 can roll flexibly. Through its fixed connection with the material conveying plate 19, the coordinated movement of the material conveying plate 19 and the roller 21 is achieved.

[0023] The number of fine-tuning hydraulic pumps 14 corresponds to the number of lifting sliding grooves 13, with each fine-tuning hydraulic pump 14 corresponding to one lifting sliding groove 13. This ensures that the height adjustment of the left and right sides of the material conveying plate 19 can be independently controlled, improving adjustment accuracy. Spring 17 is sleeved on the inner surface of the lifting sliding groove 13, ensuring that spring 17 will not shift laterally when under force, ensuring that the force transmission direction is always perpendicular, and improving equipment stability. Pressure sensor 16 is located at the top of the inner surface of the lifting sliding groove 13. Installed at the top of the lifting sliding groove 13, pressure sensor 16 can accurately receive the pressure signal transmitted by the sliding plate 18, avoiding external interference and ensuring measurement accuracy. Pressure sensor 16 is located on the adjusting contact plate 1. Above the weighing plate 5, this positioning allows the pressure applied by the adjusting contact plate 15 to the sliding plate 18 via the spring 17 to be directly transmitted to the pressure sensor 16, enabling real-time pressure monitoring. The roller 21 is located on the lower surface of the material conveying plate 19, contacting the lower surface of the material conveying plate 19 to transfer the weight of the material conveying plate 19 to the weighing plate 5. Simultaneously, it allows the material conveying plate 19 to slide slightly in the horizontal direction to accommodate minor displacements during the weighing process. The sliding plates 18 are symmetrically arranged on the left and right sides of the material conveying plate 19. This symmetrical arrangement ensures the balance of the material conveying plate 19 during lifting and lowering, preventing tilting and ensuring the accuracy of the weighing results. The mounting bracket 1 contains an auxiliary assembly. The auxiliary components are the core parts of the equipment that enable automatic weighing and feeding. These components work together to complete operations such as material storage, conveying, weighing, and releasing. The auxiliary components include a controller 2, a weighing device 3, a connecting rod 4, a storage tank 6, an observation window 7, a discharge pipe 8, and an electric valve 9. The controller 2, as the control core, receives feedback signals from the weighing device 3 and the pressure sensor 16, and controls the operation of the electric valve 9 and the fine-tuning hydraulic pump 14. The weighing device 3 is used to accurately measure the weight of the material. The connecting rod 4 connects the weighing device 3 to the weighing plate 5, transmitting the weight signal. The storage tank 6 stores polyaluminum chloride material. The observation window 7 is used to observe the remaining amount of material in the storage tank 6. The discharge pipe 8 transports the material from the storage tank 6 to above the material conveying plate 19. The electric valve... Door 9 controls the release of materials. A weighing device 3 is fixedly connected to the inner surface of the mounting bracket 1. The weighing device 3 is securely installed via the mounting bracket 1, ensuring it will not shift during operation and guaranteeing the accuracy and stability of the weighing data. A connecting rod 4 is fixedly connected to the output end of the weighing device 3, connecting it to the weighing plate 5. This allows the weight on the weighing plate 5 to be accurately transferred to the weighing device 3, achieving precise measurement of the material weight. A controller 2 is fixedly connected to the front surface of the mounting bracket 1. The controller 2 is installed on the front surface of the mounting bracket 1 for easy operation and monitoring by the operator. It is also connected to various sensors and actuators via signal lines to achieve intelligent control of the entire equipment. A storage tank 6 is fixedly connected to the upper surface of the mounting bracket 1.The storage tank 6 is stably supported by the mounting bracket 1 and is used to store a large amount of polyaluminum chloride material, providing material support for the continuous operation of the equipment. An observation window 7, made of transparent material, is provided on the front surface of the storage tank 6, allowing operators to monitor the remaining material level in the tank in real time and replenish it promptly. A discharge pipe 8 is fixedly connected to the lower surface of the storage tank 6, serving as a material conveying channel to guide the polyaluminum chloride material in the storage tank 6 to the container above the material conveying plate 19, ensuring that the material accurately falls to the target location. The discharge pipe 8 extends into the interior of the mounting bracket 1, shortening the material conveying distance and reducing material waste. To minimize material loss during conveying and improve feeding efficiency, an electric valve 9 is installed on the outer surface of the discharge pipe 8. The valve 9 is controlled by a controller 2 to precisely control the amount and speed of material released. The upper surface of the connecting rod 4 is fixedly connected to the weighing plate 5. This fixed connection ensures the shortest force transmission path between the weighing plate 5 and the weighing device 3, reducing losses and interference during force transmission and improving weighing accuracy. The discharge pipe 8 is located above the material conveying plate 19. The position of the discharge pipe 8 allows the material released from it to fall directly into the container on the material conveying plate 19, preventing spillage and ensuring the accuracy and stability of the feeding process.

[0024] The material conveying plate 19 is used to hold containers containing polyaluminum chloride. The material conveying plate 19 provides a stable support platform for the containers, ensuring that the containers will not shake or tip over during the material receiving process, thus guaranteeing the accuracy of the weighing results. When the container is initially stable with the weighing plate 5, the weighing device 3 will first deduct the gross weight. After the container is placed on the material conveying plate 19 and stabilized, the weighing device 3 automatically records the weight of the container and deducts it from subsequent measurement results to obtain the actual net weight of the material. Then, the controller 2 controls the electric valve 9 to release the material. The controller 2 controls the electric valve 9 to open according to the preset weight value, allowing the material to fall from the storage tank 6 into the container through the discharge pipe 8. The controller 3 controls the switch based on the feedback data from the weighing device 3. The weighing device 3 feeds back the weight data of the material to the controller 2 in real time. When the weight of the material reaches the preset value, the controller 2 immediately controls the electric valve 9 to close, stopping the material release and achieving precise automatic weighing and feeding control.

[0025] Working Principle: First, confirm that the storage tank 6 contains sufficient polyaluminum chloride material. Check the remaining material level through the observation window 7. Connect the power supply to the equipment and start the controller 2 to put the equipment into standby mode. Operate the linear motor 10 to drive the moving base 11 and connecting plate 12 to move to the appropriate position. Place the container containing polyaluminum chloride onto the material conveying plate 19. Fine-tune the operation of the hydraulic pump 14. By adjusting the abutment plate 15 and spring 17, push the sliding plate 18 to lower the material conveying plate 19 until the roller 21 makes stable contact with the contact groove 20 on the weighing plate 5. After the weighing device 3 detects that the weight is stable, it automatically deducts the gross weight of the container and feeds the data back to the controller 2. The operator sets the target material quantity through the controller 2. The controller 2 controls the electric valve 9 to open according to the set value, and the polyaluminum chloride material falls from the storage tank 6 into the container through the discharge pipe 8. The weighing device 3 monitors the material weight in real time and continuously feeds the data back to the controller 2. When the material weight is close to the target value, the controller 2 gradually reduces the opening degree of the electric valve 9 to slow down the falling speed of the material and achieve precise feeding. When the material weight reaches the target value, the controller 2 immediately closes the electric valve 9 to stop the material release, and the fine-tuning hydraulic pump 14 reverses its action to make the material conveying plate 19 rise and detach from the weighing plate 5. The linear motor 10 is operated to transport the container containing the material to the designated location for subsequent processing. When the material in the storage tank 6 is insufficient, the material is replenished in time.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
