The opening and closing cap of the blow molding machine is an indispensable key component in the blow molding process, and the opening and closing of the cap of the blow molding machine plays an important role in the whole blowing process, with the functions of mold closing, plastic extrusion, bottle molding, bottle demoulding, etc.
The electric opening and closing cap and the upper and lower opening and closing caps of the blow molding machine are two different opening and closing mechanisms, which are used to control the opening and closing action of the mold. Here's how they contrast:
Motorized lid opening
Open and close the lid up and down
Principles and methods of operation
Motorized lid opening
Features: Driven by electric motor, fast and smooth opening and closing action is realized through the transmission system.
Operation mode: The operator starts, stops and adjusts the action of the electric opening and closing cover through the control panel such as buttons, switches or touch screens.
Open and close the lid up and down
Features: Driven by hydraulic system, the up and down movement of the mold is controlled by hydraulic cylinders, guide rails and transmission devices to achieve opening and closing action.
Operation mode: The upper and lower opening and closing caps are usually operated and controlled by the control system of the blow molding machine through PLC or other computer control equipment.
Flexibility and adjustability
Motorized lid opening
Advantages: Driven by electric motor, it has high flexibility and adjustment ability.
Adjustment ability: The opening and closing speed can be adjusted by adjusting the motor speed or the transmission ratio of the transmission system to meet the production requirements of different products.
Open and close the lid up and down
Advantages: Hydraulic system is usually used, and the opening and closing speed and strength are relatively stable.
Adjustment ability: The adjustment range is limited, and it is necessary to adjust the action of opening and closing the upper and lower lids by adjusting the pressure and flow of the hydraulic system.
Productivity and stability
Motorized lid opening
Advantages: It has high flexibility and adjustment ability, and can adjust the opening and closing speed and strength to improve production efficiency and stability.
Capacity increase: The action is usually faster, which shortens the cycle time and increases the capacity of the blow molding machine.
Open and close the lid up and down
Advantage: Movements are generally relatively stable.
Adjustment ability: The adjustment range is limited, and the opening and closing speed is slow, which may have a certain impact on production efficiency.
In general, electric opening and closing caps and upper and lower opening and closing caps are common opening and closing mechanisms in bottle blowing machines, each of which has certain advantages and applicable scenarios. Electric lids are generally more suitable for situations where flexible opening and closing speed and force are required, while upper and lower lids are relatively stable and suitable for production environments where speed is not so demanding. Choosing the right opening and closing mechanism depends on the specific production needs and the design of the blow molding machine.
