Description

Technical Field

[0001] This utility model relates to the field of material mixing technology, specifically a continuous automatic batching and mixing device. Background Technology

[0002] The current material mixing process mainly involves dividing a batch of materials to be mixed into batches, measuring them separately according to the formula requirements, and then transferring them to a mixing machine for mixing. The next batch of materials can only be measured and mixed after the previous batch has been mixed. This mixing process requires manual participation throughout, resulting in low efficiency, increased labor costs, and the possibility of product defects due to human error, further increasing enterprise costs.

[0014] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures and features in one embodiment may be advantageously incorporated into other embodiments.

[0015] To more clearly describe a continuous automatic batching and mixing device, a detailed description is provided below with reference to the accompanying drawings: As shown in the figure, a continuous automatic batching and mixing device includes a feeding elevator 1, a hopper 2, a weighing sensor 3, an adjustable star feeder 4, a weighing screw conveyor 5, and a forced mixer 6. At least two feeding elevators 1 are provided. The main body of each feeding elevator 1 is a steel frame structure. Each feeding elevator 1 is connected to a hopper 2. The upper end of the hopper 2 has a feed inlet connected to the feeding elevator 1. A weighing sensor 3 is installed on the hopper 2, with one end fixedly connected to the outer wall of the hopper 2 and the other end fixed to a crossbeam. The feeding elevator 1 transports the prepared material to the upper part through a lifting structure, and then the material is conveyed into the hopper 2 through the feed inlet. The lower end of the hopper 2 has an adjustable star feeder 4 at its discharge port. Below the 4th layer, a weighing screw conveyor 5 is installed. To ensure that the weighing sensor 3 on the hopper 2 and the weighing screw conveyor 5 are not affected by external forces, the discharge port of the adjustable star feeder 4 is softly connected to the inlet of the weighing screw conveyor 5. Each of the adjustable star feeders 4 and the weighing screw conveyor 5 is controlled by an independent servo motor. The servo motor is electrically connected to the control system. Below the weighing screw conveyor 5, a forced mixer 6 is installed. The discharge ports of all weighing screw conveyors 5 are connected to the same inlet of the forced mixer 6. To ensure that the weighing screw conveyor 5 is not affected by external forces, the discharge port of the weighing screw conveyor 5 is softly connected to the inlet of the forced mixer 6. The weighing sensor 3, the adjustable star feeder 4, and the weighing screw conveyor 5 are each electrically connected to the control system.

[0016] This embodiment takes the mixing of two materials as an example. Material 1 and Material 2 are respectively conveyed to their respective silos 2 by their respective feeding elevators 1. The control system monitors the materials in real time through the weighing sensors 3 on the silos 2. The materials in the silos 2 are precisely adjusted and measured by the adjustable star feeder 4 and the weighing screw conveyor 5 installed below them. For example, if the required weight ratio of Material 1 to Material 2 is 10:3, then the hourly feed rate of Material 1 is 1000 kg, and the hourly feed rate of Material 2 is 300 kg. The control system automatically adjusts the feed rate of Material 2 by setting the mixing ratio and the feed rate of Material 1. In addition, during the feeding process, the actual feed rate of each material measured by the corresponding weighing screw conveyor 5 is compared and calculated in real time with the theoretical feed rate of each material set by the control system. If the actual feed rate is higher than the theoretical feed rate of each material set by the system, the corresponding adjustable star feeder 4 is automatically adjusted to reduce the feed rate, and vice versa. The adjustable star feeder 4 is used to increase the material feeding capacity. The material is then fed into the same forced mixer 6 by the control system, which controls the adjustable star feeder 4 and the weighing screw conveyor 5. Finally, the finished product is discharged from the outlet of the forced mixer 6. By setting a weighing sensor 3 on the hopper 2, the material in the hopper 2 is monitored in real time. The control system sets the upper and lower limits of the material weight in the hopper 2 and provides corresponding prompts. When the upper limit is reached, the material feeding stops, and when the lower limit is reached, the material is fed in time. The feeding process is monitored in real time and automatically adjusted to keep a certain amount of material in the hopper 2. The material is then continuously fed to the forced mixer 6 in a set ratio. The finished product is discharged from the outlet of the forced mixer 6. The entire feeding, feeding and mixing process can be continuously repeated to achieve continuous feeding until all materials are mixed. There is no need for much manual intervention. This can ensure the mixing effect, improve the mixing efficiency and save enterprise costs.
