Anatomical food packaging machine

[China Packaging Network News] 1. Food packaging machine components

Food packaging machines generally consist of the following components:

1. Power section; 2. Transmission mechanism; 3. Control system; 4. Body or frame;

1. Power section

The power part is the prime mover of mechanical work. In modern industrial production, it is usually an electric motor. In some cases it also uses a combustion engine or other power machinery.

2. Transmission mechanism

The transmission mechanism plays a role in transmitting power and movement. It is mainly composed of transmission parts such as gears, cams, sprockets (chains), belts, screws, worm gears, etc. According to needs, it can be designed as a continuous, intermittent or variable-speed transportation guide.

3. Control system

In packaging machinery, from the power output, the operation of the transmission mechanism, to the action of the work executing agency, and the coordination and circulation among the various agencies, are all commanded and manipulated by the control system. In addition to the mechanical type, the control methods of modern packaging machinery include electric control, pneumatic control, photoelectric control, electronic control, and jet control. The selection of control methods generally depends on the level of industrialization and the scale of production. However, many countries still adopt control methods that are still mostly electromechanical.

4 fuselage or rack

The fuselage (or frame) is the rigid skeleton of the entire packaging machine. Almost all hair and mechanisms are mounted on its work surface or inside. Therefore, the body must have sufficient rigidity and reliable stability. The pot makes the center of gravity of the machine must be in the lowest state. However, it should also pay attention to reduce the machine support and reduce the floor space.

5. Packaging work execution agency

Packaging machinery packaging operations are completed by the working agency, it is the core part of the packaging action. More complex packaging actions are mostly implemented using tightly-moving mechanical components or manipulators. It is often the combined application and regulation of mechanical, electrical or optoelectronic components.

two. How food packaging machines work

1. The electrical part of the current automatic food packaging machine generally consists of the following:

a) The main control circuit consists of inverter and programmable logic controller (PLC) to form the control core;

b) The temperature control circuit consists of intelligent temperature control table, solid state relays, thermocouple components, etc. It has precise temperature control, intuitive display and easy setup.

c) Multipoint tracking and detection by photoelectric switches, electromagnetic proximity sensors, etc.;

2 automatic food packaging machine working principle

The quality of product packaging is directly related to the temperature system, the accuracy of the host speed, and the stability of the tracking system.

The tracking system is the control core of the packaging machine and uses forward and reverse bidirectional tracking to further improve the tracking accuracy. After the machine is running, the film mark sensor continuously detects the film mark (color mark), and at the same time, the mechanical part tracks the micro switch to detect the position of the machine. The above two signals are sent to the PLC. After the program operation, the output of the PLC is Y6 ( The chase) and Y12 (anti-recovery) control tracking motor forward and backward tracking, timely detection of packaging material errors in the production process, while providing accurate compensation and correction, to avoid the waste of packaging materials. If the test can not meet the technical requirements after tracking a predetermined number of times, it can be automatically shut down for inspection to avoid the production of waste products;

Due to the adoption of variable frequency speed regulation, the chain transmission is greatly reduced, the stability and 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 multi-functional, fully automatic high-tech level of the packaging machine. To make it both beautiful and stylish appearance, there are healthy minds.

Although the application function of the food packaging machine is relatively simple, it has high requirements on the dynamic performance of the drive, and the system requires a fast dynamic follow-up performance and a high steady-speed accuracy. So must consider the dynamic technical indicator of the frequency converter, choose the high-performance frequency converter to meet the requirement.
