In the processing and application of plastic films, weight-increasing and weight-loss automatic batching systems each have their own advantages, and film manufacturers can choose according to their own needs.

The filling system realizes networked and centralized visualization of the liquid low-temperature filling operation system. Through the RS485 interface and the ARM control system communicating with the Modbus RTU protocol, the preset amount, preset volume and arbitrary liquid addition can be realized by selecting the working mode. Choice of 3 working modes.

The flour multi-feed pneumatic conveying system is to realize the specific requirements of the material required to be stored for several days before the mixing process proposed by the enterprise through the multi-storage tank, and at the same time achieve the purpose of continuous feeding. The system greatly improves the degree of automation of the enterprise, but because the pneumatic system itself has the disadvantage of large energy consumption, if the system conveying process parameters are not designed properly, it will produce very high energy consumption. Therefore, from the perspective of economic benefits of enterprises, it is very important to study the energy consumption of the system. In order to rationally design the parameters of the pneumatic conveying system, this paper analyzes the effects of the mixture ratio of fuel and gas, the pneumatic conveying speed and the diameter of the pipeline on the energy consumption through orthogonal experimental design method, and concludes that the mixture ratio of fuel and gas and the pneumatic conveying speed have the most significant effects on the energy consumption. The influence of pipe diameter is relatively small, which provides a theoretical basis for further regression analysis of system energy consumption and optimization of process parameters.

As a guarantee of consumer interests, the net content of prepackaged food has always been one of the focuses of regulatory authorities. How to reduce the loss as much as possible under the premise of complying with the relevant regulations reflects the management level of the enterprise. This paper introduces the factors that produce measurement errors in the packaging process of edible oil, such as mechanical accuracy, temperature of filling oil and the adjustment of production speed, and puts forward the relevant solutions according to these factors.

The hopper scale is a device suitable for hopper weighing feeding and discharging control during unloader operation; dynamic load tilt control of the hopper; vibrating feeder vibration point setting control; stock stop vibration point control; material level loading warning and alarm point setting control.

The online sorting machine completes the collection of weight signals and sends the weight signals to the controller for processing. The infeed conveyor ensures sufficient spacing between the products mainly by increasing the speed. The outfeed conveyor is used to transport the inspected products away from the weighing area.
