They are characterized by high strength, good durability, and a wide variety of shapes, and are widely used in architectural decoration and wall cladding. During the production of GRC panels, cement, glass fiber, additives, and other raw materials must be mixed in precise proportions; therefore, quantitative material feeding is a crucial step in ensuring product quality.

[0003] Existing quantitative feeding devices have the following shortcomings in practical use:

[0004] First, raw materials tend to clump together in the storage tank, leading to uneven feeding and affecting the subsequent mixing effect;

[0005] Secondly, the control accuracy of the feeding amount is low, and the coordination between the weighing sensor and the feeding mechanism is poor, often resulting in excessive or insufficient feeding. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a quantitative feeding device for the production of GRC sheet, which overcomes the shortcomings of the prior art and effectively solves the problems of uneven feeding and low control accuracy of feeding amount.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A quantitative feeding device for GRC sheet production includes a frame, a storage tank extending through the inner wall of the frame, a fixing ring welded to the outer wall of the storage tank, a weighing sensor fixedly connected between the fixing ring and the frame, a feeding pipe at the bottom of the storage tank, a conveying auger inside the feeding pipe, a first servo motor fixedly connected to the outer wall of one end of the conveying auger via a coupling, and a weighing platform at the bottom of the outer wall of one end of the feeding pipe.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 Example 1: A quantitative feeding device for GRC sheet production includes a frame 1, a storage tank 2 is provided through the inner wall of the frame 1, and a fixing ring 3 is welded to the outer wall of the storage tank 2. A weighing sensor 4 is fixedly connected between the fixing ring 3 and the frame 1. A solenoid valve 9 is fixedly connected to one side of the outer wall of the storage tank 2 through a flange, and a feed pipe 10 is fixedly connected to the outer wall of one end of the solenoid valve 9.

[0025] The weighing sensor 4 can detect the total weight of the storage tank 2 and the raw materials inside in real time, providing a data basis for raw material replenishment and feeding control. When the weight of the raw materials in the storage tank 2 is lower than the set value, the weighing sensor 4 transmits the signal to the PLC controller 19, which controls the solenoid valve 9 to open and replenish the raw materials into the storage tank 2 through the feed pipe 10 to ensure sufficient storage.

[0026] In this embodiment, by setting a second servo motor 14 and a stirring rod 15 on the top of the storage tank 2, the stirring rod 15 can continuously stir the raw materials in the storage tank 2 to prevent clumping and ensure that the raw materials are loose and uniform. At the same time, the conveying auger 6 in the feeding pipe 5 conveys the raw materials at a uniform speed under the drive of the first servo motor 7, avoiding the phenomenon of raw material accumulation or material interruption in the traditional feeding method and improving the stability of feeding.

[0027] In the second embodiment, a feeding pipe 5 is provided at the bottom of the storage tank 2, and a conveying auger 6 is provided inside the feeding pipe 5. A first servo motor 7 is fixedly connected to the outer wall of one end of the conveying auger 6 through a coupling, and a weighing platform 8 is provided at the bottom of the outer wall of one end of the feeding pipe 5.

[0028] The feeding pipe 5 at the bottom of the storage tank 2 is the channel for conveying raw materials. The internal conveying auger 6 is connected to the first servo motor 7 through a coupling. The speed of the first servo motor 7 can be adjusted by the PLC controller 19, thereby controlling the conveying speed of the raw materials and ensuring the accuracy of the weighing data.

[0029] In this embodiment, the weighing sensor 4 between the fixed ring 3 and the frame 1 can monitor the weight change of the raw material in the storage tank 2 in real time. Combined with the weighing feedback of the raw material in the feeding cylinder 13 by the weighing platform 8, the data is transmitted to the PLC controller 19 through the signal line, which accurately controls the start, stop and speed of the first servo motor 7 to achieve precise control of the feeding amount and improve production efficiency.

[0030] The bottom outer wall of the frame 1 is provided with a cabinet 18, and a support platform 11 is fixedly connected to one side of the outer wall of the cabinet 18. The weighing platform 8 is installed on the top outer wall of the support platform 11. The top outer wall of the weighing platform 8 is provided with a positioning ring 12, and a material picking cylinder 13 is placed inside the positioning ring 12 on the top outer wall of the weighing platform 8. The material picking cylinder 13 is located at the bottom of one end of the feeding pipe 5.

[0031] The positioning ring 12 on the top of the weighing platform 8 is used to fix the material taking cylinder 13 and prevent the material taking cylinder 13 from moving during the feeding process. The material taking cylinder 13 is located at the bottom of one end of the feeding pipe 5 and can accurately receive the raw materials discharged from the feeding pipe 5, ensuring that all the raw materials fall into the material taking cylinder 13 and reducing spillage.

[0032] The top outer wall of the storage tank 2 is fixedly connected to a second servo motor 14 by screws, and the output shaft of the second servo motor 14 is fixedly connected to a stirring rod 15 by a coupling. The stirring rod 15 is located inside the storage tank 2.

[0033] The second servo motor 14 at the top of the storage tank 2 is fixed with screws, and the stirring rod 15 connected to its output shaft extends into the interior of the storage tank 2. When the second servo motor 14 is started, the stirring rod 15 rotates to stir the raw materials, preventing the raw materials from clumping due to standing, ensuring the fluidity of the raw materials, and laying the foundation for smooth feeding in the future.

[0034] The bottom of the storage tank 2 is welded with a discharge port 16, and the top of the outer wall of the other end of the feeding pipe 5 is welded with a receiving port 17. The discharge port 16 is slidably connected to the inner wall of the receiving port 17.

[0035] The discharge port 16 at the bottom of the storage tank 2 is slidably connected to the inner wall of the inlet port 17 of the feeding pipe 5, which ensures that the raw materials in the storage tank 2 can flow smoothly into the feeding pipe 5 without affecting the weight detection of the storage tank 2 under the action of the weighing sensor 4, and ensures that the weighing data is not interfered with by the connection structure.

[0036] A PLC controller 19 is installed on one side of the outer wall of the cabinet 18, and the PLC controller 19 is connected to the weighing sensor 4, the first servo motor 7, the weighing platform 8, the solenoid valve 9 and the second servo motor 14 through signal lines.

[0037] The PLC controller 19 on one side of the cabinet 18 is the control core of the device. It is connected to the weighing sensor 4, the first servo motor 7, the weighing platform 8, the solenoid valve 9 and the second servo motor 14 through signal lines. It receives feedback signals from each component and issues control commands to realize the coordinated work of each mechanism and ensure the automation and accuracy of the quantitative feeding process.

[0038] Working principle: When the device is working, the feeding parameters are first preset through the PLC controller 19. During the feeding stage, the solenoid valve 9 is opened, and the raw material enters the storage tank 2 through the feed pipe 10. The weighing sensor 4 monitors the weight of the storage tank 2 in real time. After the preset storage amount is reached, the PLC controller 19 closes the solenoid valve 9.

[0039] Before feeding, the second servo motor 14 is started, driving the stirring rod 15 to stir the raw materials in the storage tank 2 to prevent clumping. The feeding cylinder 13 is placed into the positioning ring 12 of the weighing platform 8 and fixed, and the initial weight data of the weighing platform 8 is transmitted to the PLC controller 19.

[0040] During the feeding stage, the PLC controller 19 starts the first servo motor 7, and the conveying auger 6 rotates. The raw material in the storage tank 2 enters the feeding pipe 5 through the discharge port 16 and the receiving port 17, and is pushed to the picking cylinder 13 by the conveying auger 6. The weighing sensor 4 monitors the decrease in weight of the storage tank 2, while the weighing platform 8 monitors the increase in weight of the picking cylinder 13. The data from both are fed back to the PLC controller 19 in real time.

[0041] When the raw material in the feeding cylinder 13 reaches the preset weight, the PLC controller 19 shuts down the first servo motor 7, stopping the feeding. After completion, the feeding cylinder 13 can be removed, and the device waits for the next feeding command. The entire process achieves fully automatic and precise control.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
