In industrial production, for the raw materials that use a variety of raw materials to be mixed according to the weight of their respective components, usually the weight of each component is weighed one by one with a weighing device, and then put into the batching hopper and mixed. Formula raw materials. This kind of formula/ingredient has low work efficiency, high labor intensity, high dust in the working environment, and it is difficult to ensure the accuracy of the ratio of each raw material component of each formula. Contents of the utility model The purpose of the utility model is to overcome the shortcomings in the prior art and provide an automatic weighing batching machine with high working efficiency and capable of weighing multi-component materials. The purpose of the utility model is achieved through the following ways. Automatic weighing batching machine, including raw material conveying device, batching hopper, screw barrel feeding device and control electric cabinet, its main structure is that it includes PLC touch screen control system, two or more batching hoppers, PLC touch screen The control system is connected with the batching hopper. The PLC touch screen control system includes a PLC touch screen and a weighing controller. The PLC touch screen output port is connected to the weighing controller, and the weighing controller is located above the batching hopper. The weighing weight of each batching hopper is set through the PLC touch screen, and the raw material conveying device conveys the raw materials to the batching hopper according to the preset weight ratio. The real-time weight value is displayed on the touch screen through the weighing controller through the communication port, which is convenient for the operator Select or change the formula on the touch screen, and adjust the conveying speed to realize real-time control. After the raw materials are stirred and mixed uniformly in the batching hopper, the formula raw materials are output through the screw and barrel feeding device. The PLC touch screen control system of the automatic weighing batching machine also includes a frequency converter, which is connected to the weighing controller. With the weighing controller controlling the blanking volume, the feeding speed is adjusted at the same time. Each said batching hopper is respectively connected with a weighing controller. Respectively detect the amount of raw materials in each batching hopper. The utility model has the advantages that the weighing of multi-material and multi-formulation materials can be accurately controlled, and the entire process of conveying, weighing, quantitative feeding, feeding, and unloading is automatically controlled, and the degree of automation is high.
Specific embodiment
Hereinafter, the utility model will be further explained in conjunction with the drawings. As shown in Figure 1, Figure 2, Figure 3, set the proportional weight and speed of different formulas on the touch screen I, press the start switch, and the inverter 31 will start to run. The slow-speed screw runs to discharge the material, and the inverter stops when each set weight is reached. When each batching hopper weighing controller 3 detects that the material amount of each batching hopper 4 reaches the set lower limit, each batching hopper alarm alarms that the formula is insufficient. At the same time, the raw material conveying device 2 of each batching hopper is automatically started to run and feed, and it will automatically stop when the upper limit is reached. During the unwinding process, the weighing controller 3 displays the unwinding weight, displays each unwinding process, and automatically adjusts the error, and automatically alarms if the error is exceeded. After the raw materials are uniformly stirred and mixed in the batching hopper, the formula raw materials are output from the discharge port 6 through the screw and barrel feeding device 5. In this way, the PLC touch screen control system automatically completes the batching cycle after receiving each signal. In this embodiment, the touch screen is an Omron PLC touch screen, the frequency converter is a general frequency converter, and the weighing controller is a cumulative weighting controller.

An automatic weighing batching machine, comprising a raw material conveying device (2), a batching hopper (4), a screw barrel feeding device (5) and a control electric cabinet, characterized in that it also includes a PLC touch screen control system, There are two or more batching hoppers (4), and the PLC touch screen control system is connected with the batching hopper.
2. The automatic weighing batching machine according to claim 1, wherein the PLC touch screen control system includes a PLC touch screen (I), a weighing controller (3), a PLC touch screen output port and a weighing control The weighing controller is located above the batching hopper.
3. The automatic weighing batching machine according to claim 1, characterized in that the PLC touch screen control system further includes a frequency converter (31) connected to the weighing controller (3).
4. The automatic weighing batching machine according to claim 1, characterized in that, each batching hopper (4) is respectively connected with a weighing control (3).
Patent Abstract This utility model discloses an automatic weighing batching machine, including a raw material conveying device, a batching hopper, a screw barrel feeding device and a control electric cabinet. Its structure points also include a PLC touch screen control system. The batching hopper is Two or more, PLC touch screen control system is connected with the batching hopper. Realize the automatic weighing and batching of different raw materials according to the formula, the whole process is automatically controlled, the degree of automation is high, and the work efficiency is improved.[Gravimetric blender]
