The weighing automatic vibration mixer consists of two parts: hardware and software. The hardware part mainly consists of a mixing tank body, mixing tank cover, mixer, load-bearing weighing module, weighing instrument, transmission device, shaft seal device, etc. It also includes a programmable controller and an upper industrial control computer Weighing system; The software part mainly includes the control algorithm of the programmable controller and the monitoring program of the upper industrial control computer. In the industrial batching process, there are two commonly used weighing methods, namely feed weighing and discharge weighing. At the beginning of weighing, material is fed into the hopper scale through the feeding device. When the weighing value reaches the set value, the feeding is stopped, and then the gate is opened to discharge the material. When using the feeding weighing method, due to the influence of the drop, after stopping the feeding, some of the material still falls into the hopper scale in a free fall manner in the air. In order to ensure the accuracy of the ingredients, it is necessary to design a control algorithm for terminating the feeding advance, which controls the termination of the feeding advance to reduce the impact of the drop on the accuracy of the ingredients and keep the actual ingredient value within the error range.

This algorithm utilizes the characteristic of multiple repeated weighings in the production process of the mixer, and uses the result of each weighing to correct the advance amount of termination feeding for the next batching. After a limited number of trial preparations, the static weighing value of the prepared material can be kept within the error range. Unloading weighing is the process of first loading materials that consistently exceed the formula requirements into a hopper, and then unloading the material from the hopper to the outside for weighing. The weight of the material that falls is the weight of the material to be prepared. According to the actual situation of our factory's process flow, computer matching is carried out before the transportation of two types of raw materials. Based on the ratio (i.e. percentage) of the two types of raw materials set by the operator on the touch screen, the computer will automatically calculate the operating speed. Then, based on the weight signals sensed by the two Electronic scales, the computer can calculate and analyze at any time to control and adjust the speed to achieve the set ratio requirements. According to the corresponding set values before operation, the normal operation of the automatic batching equipment, including PID regulation; Detect and monitor the instantaneous flow rate, daily cumulative, monthly cumulative, annual cumulative and other parameters of the ingredient process. During the entire production process, once the production plan is formulated, the controller PLC will weigh each raw material according to the plan. At the same time, the computer can perform statistical analysis on various data during the production process, automatically generating daily and monthly reports including formulas and various material dispensing quantities, which will be beneficial for modern management such as product cost accounting and quality analysis.

The mixing weighing machine adopts a weighbridge for measurement. The mixing bin is set on the weighbridge, and the upper part of the mixing bin is open. There is a discharge port at the bottom of the mixing bin, which can be used for weighing. The funnel is set above the mixing bin, and there are multiple funnels. The funnel is equipped with an outlet, which is connected to the mixing bin. A filter screen is set between the funnel and the mixing bin, and the funnel can be used for weighing; Material warehouse, used for storing chemical additives, equipped with an outlet connected to a funnel; The weighbridge is equipped with a weighing module, and the funnel is suspended under the weighbridge through the weighing module. The weighing scale is equipped with a connecting component, and the weighing module is hinged to the weighing scale through the connecting component. The connecting component includes a connecting part, a locking buckle, and a locking buckle. The connecting part is set on the weighing scale, and the locking buckle is hinged to the connecting part. One end of the locking buckle is hinged to the locking buckle, and the other end of the locking buckle is fixedly connected to the weighing module. The lock buckle is equipped with a locking part, which is spherical in shape, and the lock buckle is sleeved on the locking part. The weighing scale is vertically equipped with a guide rod, which is fitted with a slider. There are ball bearings between the slider and the guide rod, and the slider is connected to the funnel. The outlet of the weighing mixer is equipped with a butterfly valve, which is used to control the opening and closing of the outlet. A balance block is installed outside the outlet, and the balance block and butterfly valve are symmetrically placed on both sides of the outlet.
