Disinfectant filling can be done by weighing method, using with serial port (RS232) based on VB platform preparation, its function includes data acquisition, data processing, generating files, and data printing. In order to adapt to different specifications of the filling needs, the system has two ways of working automatically and manually: secondly, in the system can be manually set up the filling parameters. Parameter settings include: setting the weight of the filling container (i.e., tare weight), setting the filling weight (i.e., net filling volume).

Medical disinfectant filling machine is connected to the RS232 serial port of the weighing system, after reading the information of weighing data through the serial port, the data exchange and communication between the serial port of the computer and the filling machine will be carried out, according to the need to formulate the barrel ID database and the staff database as well as the weight database, the barrel ID database stores the ID number of the barrel and barrel regulation, etc., and the staff database stores the staff's number and password, etc., and the weight database The weight database stores the vehicle number of the filling station and the weight of each filling.

Lubricant filling machine to establish the barrel ID and information management database, in order to facilitate the data uploaded for effective query operation, filling machine feedback appropriate information in order to facilitate the implementation of the set operation. In the quantitative filling control circuit in the filling gun solenoid valve contact switch to maintain a normally closed state, after receiving the target command, start filling weighing module to display the current filling volume.

The weighing module can be conveniently installed on containers of various shapes, and can be conveniently charged, mixed or mixed in this container. Through the combination of weighing sensor, instrument and control system. The system can achieve the weighing and metering of the tank, so as to control it. The weighing system mainly consists of multiple sensors, multi-channel junction boxes (including amplifiers), display instruments and multi-channel control signals.

The Constant pressure feeding system is mainly used in plastic injection, extrusion or hollow process where a variety of raw materials are mixed according to weight ratio. The setting data will not be lost after the power is cut off by EEPROM, no battery is used; Use the human-machine interface status display touch keyboard data input, more convenient operation, but also can store a large number of formula data (500 groups); High speed and high precision AD grab weight faster and more stable; All the boredom is evenly mixed after gravity measurement, which can strictly control the accuracy. Check the weight data and the selected raw materials to ensure the precision and accuracy of the mix.

The positive pressure batching system first transfers different materials to the hopper of each weight loss scale by the conveying system, automatically corrects the deviation from the set point by adjusting the feeder speed, stops the screw conveyor and outlet gate valve immediately before reaching the target weight, and completes the discharge of a single weight loss scale. The rest weight loss scales complete the discharge successively in this process.

The positive pressure batching system uses the combination of negative pressure pneumatic conveying and weighing technology to complete the material conveying and batching. The system is composed of raw material feeding bin, conveying pipe, feeding valve group and suction feeding multi-component measuring scale. The material is sucked into the storage bin through vacuum negative pressure, and the material is measured while sucking. According to the flow of the material (powder), the arch breaking device can be added to assist the flow, and up to 20 pipes can be connected to the measuring scale at the same time for measurement. Solid material, durable; Meet a variety of material measurement, saving space and cost.

The pneumatic batching system adopts positive and negative two-way tracking, which further improves the tracking accuracy. After the batching operation, the weighing module constantly detects and tracks the position of the micro-switch to detect the machine, and after the signal is sent to the PLC through the program calculation, the positive and negative tracking of the motor is controlled by the PLC output, and the error of the packaging materials in the production process is found in time and accurately compensated and corrected, avoiding the waste of packaging materials. If the detection can not meet the technical requirements after tracking the predetermined number of times, it can automatically stop for inspection to avoid the generation of waste products.

The operator of the Intermittent mixer inputs the proportion of each raw material, the machine will calculate the weight of each raw material by combining the weight of each ingredient, and then control the opening and closing of the metering valve to distribute the raw materials to the weighing hopper, when each raw material is completed in accordance with the proportion of the raw material, the raw material in the weighing hopper will be discharged to the lower part of the agitator for stirring, and after the completion of the mixing, the whole process is complete.
