The 7 major components of the blister machine and its role

I think everyone is right.The components and functions of the blister machineI don't know much about it. Today, the editor of this website will introduce to you the 7 major components of the blister machine and their functions ~! Let's read this article with Xiaobian!

1. clamping equipment

When the plastic sheet is formed, the sheet is fixed to the clamping device. In the hot forming of the general and composite type of hot forming machine more convenient to fix the various sizes of sheet clamping device. Some of the entire molding machine with a set of clamping frame.

2. heating equipment

Thermoplastic sheet and film vacuum molding process, one of the main processes is the sheet heating. The duration and quality of electrical heating depends on the structure of the heater, the thermal inertia of the temperature heat transfer behind the radiant surface, the distance between the sheet and the heater, the radiant energy absorption coefficient, the characteristics of the heater surface, and the thermophysical properties of the material. Commonly used heaters are electric heaters, crystal radiators and infrared heaters.

3. vacuum equipment

The vacuum system is composed of vacuum pump, gas tank, valve, pipeline and vacuum gauge. In vacuum forming, a separate type of vacuum pump is often used. The vacuum degree of this pump should reach 0.07~0.09 Mpa(520mmHg). The gas storage tank is generally a cylindrical box welded with thin steel plates, and the bottom is oval. The capacity of the gas storage tank should be at least half larger than the capacity of the largest molding chamber. The vacuum line must be equipped with appropriate valves to control the vacuum narrow capacity. The rotational power of the vacuum pump is determined by the size and speed of the molding equipment, and the equipment with larger or faster molding speed is usually as large as 2-4KW. The size of the vacuum central system depends on the specific production and development requirements of the plant.

4. compressed air equipment

The pneumatic system can be composed of the molding machine with its own compressor, air storage tank, workshop main pipe set, valves, etc. The molding machine needs compressed air with a pressure of 0.4-0.5MPa, and various vacuum blister molding machines widely use piston air compressors. It can also be supplied with large spiral air compressors throughout the plant. In addition to a large amount of compressed air should be molded, and when part of it is used for demoulding, external cooling of primary products and

The power to manipulate the mold frame and move the sheet and other mechanical parts.

5. cooling equipment

In order to improve production efficiency, vacuum plastic molding products often need to be cooled before demoulding. Desirably, both the inner and outer surfaces of the article in contact with the mold are cooled, and preferably a mold with internal cooling coils is used. For non-metallic molds, such as wood, gypsum, glass fiber reinforced plastic, epoxy resin and other molds, because they cannot be cooled by water, air cooling can be used instead, and water mist can be added to cool the outer surface of the vacuum plastic forming parts. If natural cooling is used in production, annealing parts can be obtained, which is beneficial to improve the impact resistance of the parts. Although water cooling has high production efficiency, the internal stress of the parts is large.

6. Demoulding Equipment

Demoulding is to remove the product from the mold, usually whether it is a concave mold or a convex mold, most of the occasions are due to the cooling shrinkage of the product and close to the mold, so through the vacuum suction hole or blowing in the opposite direction to demoulding.

Especially for the mold with small demoulding inclination or with concave mold, the demoulding mechanism is used to contradict or shake the demoulding, and sometimes the sheet and the mold are coated with demoulding agent or the surface of the mold is sprayed with Teflon.

7. control equipment

The control system generally includes the control of various parameters and actions of instruments, meters, pipelines and valves in the process of vacuum blister molding and finishing. Control methods include manual, electrical-automatic control, computer control, etc. The specific selection should be based on the initial investment labor costs, technical requirements, raw material costs, production and maintenance equipment costs and other factors.
