The automatic control system of the weighing reaction pot is equipped with various connections on the container according to the process requirements to meet the requirements of feeding, discharging, exhaust, etc. To heat or remove reaction heat from materials, an outer jacket or inner coil is often installed. The system receives ingredient instructions and heats, mixes, and weighs the materials in the weighing tank. It has a simple structure and fast speed, with a three-level feeding method. Adopting a high-precision dual measuring bucket structure, alternating operation, fast storage of 16 measuring ranges and material data, easy operation through button selection. The weighing control system has multiple functions such as automatic error correction, automatic alarm for out of tolerance, fault prompt, and automatic material accumulation. The data is output by a printer and processed by a computer. Can be used with elevators and conveyors. The plastic heat sealing machine is equipped with ingredients. The Weighing system application configuration software is used to complete data acquisition and process control, supporting multiple communication protocols, providing users with various device support, rich and colorful dynamic images, and powerful system functions. It is transmitted to the central control room for centralized monitoring and management through high-speed network, and the central control room host also transmits control commands to the PLC measurement and control terminal through high-speed network, implementing decentralized management of each unit. It integrates computer technology, automatic control, communication technology, and weighing technology, with complete control functions, centralized display and operation, convenient data processing, simple installation and maintenance, and easy system expansion. Structurally, the problem of "danger concentration" in computer centralized control systems has been solved, achieving "centralized management and dispersed danger". The system is stable and reliable, meeting the needs of continuous production processes.

The weighing and batching machine includes a bracket. The top of the bracket is equipped with a batching bin, and the bottom of the batching bin is connected to a feeding screw. The right bottom of the feeding screw is equipped with a feeding screw outlet, and a weighing scale is installed at the lower end of the feeding screw outlet. The bottom of the electronic weighing scale is equipped with a weighing module switch, and the switch is internally equipped with a weighing sensor. The weighing sensor is electrically connected to the weighing controller, and the weighing controller is sequentially connected to a frequency converter and a motor. The motor is electrically connected to the feeding screw. The bottom of the weighing scale is equipped with a mixer, and the bottom of the mixer is equipped with a mixer switch. Raw materials enter from the batching bin, pass through the feeding screw outlet, and fall into the weighing scale through the feeding screw outlet. The weight change of the weighing scale is converted into a corresponding millivolt voltage signal change through the weighing Weighing controller, By using a weighing instrument to perform digital filtering on the digital quantity and comparing it with the set value, the current ingredient situation of the raw material is determined. The use of a frequency converter can achieve stepless speed regulation feeding. When the value reaches the set value, the pouring of raw materials into the ingredient bin and the transfer of the feeding screw are stopped. The weighing switch is turned on, and all raw materials in the weighing scale enter the mixer. The weighing switch is turned off, the feeding screw is turned on, the weighing scale side outlet is opened, and excess raw materials are collected in the container; When the next batch of raw materials needs to be prepared, repeat the above steps.
