Vacuum packing machine belongs to the category of automata. It is very difficult to classify its composition due to its wide variety, complex structure and emerging new packaging equipment.But through the analysis of the working principle and structural performance of big M packaging machinery, the common points of its composition can be found. Packaging machinery mainly consists of power system, transmission system, executive system, etc.In order to master and study the working principle and characteristics of packaging machinery, usually packaging machinery is divided as follows.
(1) packaging finishing and conveying system. The system is to arrange packaging materials,sometimes, it is necessary to cut off the products and deliver them to the designated work place one by one.For example, the delivery of wrapping paper in the candy packaging machine, cutting off the mechanism.Some systems can also complete the hoisting, shaping and positioning of bags or packaging containers in the process of supply and delivery, and some need to complete the operation of the tank cover, such as the supply and delivery system of the tank sealing machine.
(2) Metering and feeding system of packaged articles The system measures, sorts, arranges, and delivers the packaged articles to pre-customized stations.Some can also complete the packaging of goods stereotypes, segmentation. Such as the measurement of beverage filler and liquid feed system;The cookie vacuum packaging machine organizes, arranges and supplies the system.
Master transfer system a system for transferring packaging materials and packaged items from one packaging station to the next.Single position packaging machine has no transfer system.
(3) the whole packaging process is usually separated into several work stations on the packaging machine to coordinate the supply and delivery of packaging materials and packaged goods until the product is exported.The form of the master conveyer affects its appearance, so there must be a specialized agency to deliver the packaging material and the packaged goods until the product is exported.
Packaging execution mechanism packaging execution mechanism is the mechanism that directly completes packaging operation, that is, completes wrapping, filling, sealing, labeling, strapping and so on.For example, before and after the candy wrapping machine pushing sugar board, cardboard, sugar pliers and kindling hand, etc.Two rollers in a can sealing machine are also packing actuators.
(4) finished product output mechanism the finished product output mechanism is the mechanism that unloads the packaged products from the packaging machine, arranges them in a directional way and outputs them.The finished product output of some packaging machinery is completed by the main transmission mechanism or by the self-weight of the packaging products.
(5) power machine and drive system power machine is the original power of mechanical work. In modern industrial production, it is usually an electric motor,the driving system refers to the device that transfers the power and motion of the power machine to the actuator and control system so that it can realize the predetermined action.It is usually composed of transmission parts, such as belt wheel, gear, sprocket, CAM, worm wheel, worm, etc., or it is composed of transmission in various forms such as machine, electricity, liquid and gas.
(6) the control system consists of various manual and automatic devices.The output of the power, the operation of the transmission mechanism, the action and coordination of the packaging actuators and the output of the packaging products in the packaging machine are all controlled by the command of the control system.It includes control of packaging process, packaging quality, failure and safety.
(7) in addition to mechanical forms, modern packaging machinery control methods include electrical control, pneumatic control, photoelectric control, electronic control and jet control,according to the automation level of packaging machinery and production requirements.
The fuselage body is used to install, fix and contract all parts of the assembly machine, which can meet the requirements of mutual movement and position.Therefore, the body must have sufficient strength, stiffness and stability.
