Food Packaging Applications
Application of ACI Inverter in Food Packaging Machinery
一. Working principle of food packaging machine:
Pillow type automatic packaging machine of the present domestic leading and most mature and reliable design and production technology, the essence of a collection of many years of experience in the field of packaging machinery, the packing machine can be used in a variety of composite packaging film coil on the packaging of bulk food, very suitable for the majority of users need to Chinese.
(1) the electrical part of the automatic packing machine is generally composed of the following components:
A) the main control circuit is composed of frequency converter and programmable logic controller (PLC);
B) temperature control circuit is composed of intelligent temperature control meter, solid state relay and thermocouple element, precise temperature control, direct display and convenient setting;
C) by photoelectric switches, proximity sensors, etc. to achieve multi-point tracking and detection;
(2) the principle of fully automatic pillow type:
With the improvement of the degree of automation, the operation, maintenance and daily maintenance of the packaging machine is more convenient and simple, and the professional skills required for the operator is reduced. Product packaging quality is good or bad, is directly related to the temperature system, the precision of the engine speed and the stability of the tracking system.
Tracking system is the core of the packaging machine control, using the positive and reverse direction tracking, to further improve the tracking accuracy. The machine is running, the film constantly mark sensor markers in detection of film (color), and track the micro switch position of the machine, the two signal is sent to the PLC, the program after the operation, the output of the PLC (after, chase) controlled motor tracking tracking error of packing materials in the production process to discover at the same time accurate compensation and correction, to avoid the waste of packaging materials. If the detection is still unable to meet the technical requirements after the predetermined number of times, it can be automatically stopped to check to avoid the production of waste products.
By adopting the frequency conversion speed regulation, the chain transmission is greatly reduced, the stability and the reliability of the machine operation are improved, and the noise of the machine operation is reduced. It ensures the high efficiency, low loss, automatic detection and other functions of the packaging machine. Make it both beautiful and stylish appearance, but also have a healthy mind.
Although the application function of the transmission system of food packaging machine is relatively simple, the dynamic performance of the transmission has higher requirements. Therefore, it is necessary to consider the dynamic technical specifications of the frequency converter, and the high performance frequency converter can be used to meet the requirements.
V11 ACI vector inverter, can meet the requirements of the packaging machine, because it has the following characteristics:
(1) the application of speed sensorless vector control technology, automatic correction of frequency, in order to achieve load changes when the motor speed stability;
(2) with high stability and fast dynamic response, can meet the requirements of high performance transmission control. Reduce the outage time and economic loss caused by the failure of the transmission system. At the same time, the speed sensor is omitted, and the maintenance cost is low.
(3) with the advantages of rich functions, stable performance, small size, low noise operation, etc..
二. Advantages of applying ACI frequency conversion speed regulating equipment
(1) simplify the transmission system, greatly reduce the failure rate, reduce the maintenance costs of enterprises.
(2) to increase production and reduce costs. Can improve the production technology, so that the product yield and quality are improved, and can effectively save costs and achieve maximum profit.
(3) to achieve the control of the software, improve the function.
(4) through the torque compensation, to prevent the stall and restart and other functions, the realization of non trip operation; so that the production of product quality stability, efficiency and improve the quality of the product.
