What is the principle of Huaian thick sheet blister?
Time: 2022-02-16
Huaian thick sheet blister is a key process equipment for manufacturing plastic parts through a vacuum plastic film forming process with plastic plates as raw materials. Thermoplastic materials are used as raw materials, heated to a soft temperature through an oven, and then through the vacuum between the plastic material and the plastic mold Negative pressure function, the thermoplastic plastic plate is adsorbed to the blister forming work surface and cooled again.
What is the structure and function of Huaian thick sheet blister? Let's take a look.
Thick plastic inhalers are usually composed of functional structure, frame, heat generation, refrigeration and electrical control systems for plate plastic mold positioning.
(1) The function of the locking position of Huaian thick sheet plastic suction plate is generally composed of well type steel pressure box, power cylinder or pneumatic cylinder and balance. Its function is to strengthen the position of the plate mass. The pressure box of the rack-type way is an upper and lower structure, which adds a side lock to ensure that the pressure box is tightly sealed with the wooden board pad. The frame can be adjusted according to the size, separated and adjusted automatically.
(2) The structure of blister locking its position is generally composed of upper and lower molds, upper and lower mold cylinders or cylinders, and mechanisms. Its role is to strengthen the position of the blister tray and connect the model to the vacuum pipe. Locking method manual screw lock or pneumatic self-locking two methods. Synchronization can make the upper and lower models float up and down at the same time to ensure the accuracy of plastic molding.
(3) Huaian thick sheet blister frame is generally composed of a steel frame, a sealed box, and a protective door. Among them, the protection door is divided into non-use and self-operation.
(4) The heat generation of Huaian thick sheet blister is generally composed of bricks or heating pipes, oven main body and power cylinder or motor.
(5) Huaian thick sheet blister freezing is generally composed of gas, water pipe and spray head.
(6) Electrical system The electrical control system can realize the process requirements (temperature, speed, time) and various program actions of air intake together with pneumatic or hydraulic system management. Mainly PLC and touch screen, contactors, electronic components, thermostat, solenoid valves, sensors, etc. There are usually three control methods.
What is the principle of Huai 'an thick sheet blister? Let's analyze it together.
Huaian thick sheet blister and sheet blister principle is similar. The positioned material is heated to a softened state through an oven, the blister mold and its surroundings form a closed space, the air inside the cavity is instantly extracted, the plate is firmly stuck on the surface of the mold, and the product is obtained through freezing and setting.
Huai 'an thick sheet plastic forming is a cyclic process. Each cycle mainly includes feeding-heating-back blowing-plastic suction-cooling and shaping-alopecia and drunkenness. After removing the plastic part, reposition the plate (it can be received or automatically received), and then continue for the next cycle.
