During the production process, the weighing automatic mixer needs to mix various raw materials in proportion according to different varieties and predetermined formulas. The batching machine is divided into a feeding section and a batching section. The feeding section is mainly composed of equipment such as a screw machine, a hoist, a mixer, a conveyor, and a distributor. The ingredient part includes the silo, Feeder, Electronic scale, and mixer. The main function of the ingredient part is to feed various raw materials into their respective hoppers in the feeding equipment, feed them into the weighing hopper according to the given ratio of the formula, weigh them, and then send them to the mixer for a certain period of time to mix evenly into the finished product. Various fixed formulas are inputted into the touch screen in advance, and the touch screen controls the feeding, weighing, and mixing according to the proportion of the formulas. The signals from the weighing module are detected in real time to make judgments and issue commands to the various executing mechanisms of the ingredients, thereby achieving ingredient automation. The entire production system is equipped with manual control auxiliary mechanisms, which can control operation in automatic or manual mode.

The weighing mixer adopts a weighing scale, a feeding hopper, and a discharging hopper. The discharging hopper is fixed on the weighing scale, and the feeding hopper is located at the top of the weighing scale. A feeding pipe is inserted into the feeding hopper. The weighing module below the hopper scale, a storage rack for placing the weighing module, and a driving device for driving the displacement of the hopper scale are used. The driving device adopts a connecting column connected to the hopper scale, a fixed column hinged to the bottom of the connecting column, a pushing cylinder connected to the bottom of the connecting column, a fixed plate for fixing the pushing cylinder and the bottom of the fixed column, and a driver located at the bottom of the fixed plate. The bottom end of the connecting column is hinged to the cylinder shaft of the pushing cylinder, and the hopper scale can be flipped towards the discharging hopper by the pushing of the pushing cylinder. The hopper scale is In the state where the weighing module is in contact, there is a distance between the drive shaft of the driver and the fixed plate, There are two sets of driving devices located on both sides of the hopper scale. The weighing module also adopts two sets of buffer devices respectively set on both sides of the hopper scale. The buffer devices include fixed frames fixed on the connecting column and the top of the connecting column, sliding heads set at both ends of the fixed frame and sliding connected to them, sliding heads, springs set between sliding heads, and connecting rods and connecting rods respectively connected to the sliding heads and sliding heads. There are two sets of fixed seats on both sides of the hopper scale that are connected to the connecting rods and connecting rods for rotation. The fixed frame is equipped with a sliding groove that is compatible with the sliding head, and there is a receiving chamber with a height higher than the sliding groove in the groove. The spring is located in the receiving chamber. The two ends of the spring are welded to the slider and slider respectively.

The ingredient control system mainly includes the system hardware and software of the industrial computer, as well as the electrical equipment corresponding to the sampling, detection, alarm and other execution mechanisms. The system has the following main functions:

Human computer interaction and management: The various functions reflected in human computer interaction and management are an important aspect of real-time control system performance. This system has the ability to process Chinese information and provides Chinese prompts in a menu format. Operators can select and perform various operations by using function keys or cursor movement. The system provides a fixed recipe library. There are up to 100 formulas available. Operators can query, modify, or specify a working formula for stored formulas, as well as temporarily input and erase a formula. The system has dynamic display and printing functions. During the ingredient process, the touch screen can display the ingredient control flowchart on the CRT screen and dynamically indicate it with a cursor. It can also display the title and ingredient weight at the same time, allowing operators to have a clear understanding of the ingredient situation. The printer can print in Chinese. The explosion-proof electronic Weighing system can provide various production information reports to the production management department.

Real time detection and control: The system can collect real-time weighing signals of each ingredient scale, automatically peel, zero, and correct errors, and select and control the feeding according to the specified formula ratio and relevant algorithms. It can also make judgments at any time and send switch signals to the corresponding feeders, electronic weighing doors, and mixing machine doors.

Status testing and alarm: Detecting the operating status of controlled equipment during the batching process and promptly identifying problems is an important guarantee for safety production. Dynamically detect the status of the driving motors, travel switches, and other equipment of each feeder and weighing door, and immediately sound an alarm once errors or faults are detected.

On site data protection: This system has a data protection area within the touch screen. The touch screen places the current formula data and other important data in the ingredients in a protected area. If there is a sudden power outage or system failure that requires shutdown for processing, the data in the protected area will not be lost. After the on-site restoration, the batching process can still continue.
