Today, I will tell you about it.Composition and function of blister machineWhat? It doesn't matter if you don't know anything about it, then follow Shenzhen now.YonghengshengBlister machineI'll take a look at the small series.

1.Clamping equipment
When the plastic sheet is formed, the sheet is fixed on the clamping device. In the hot forming of the general-purpose and composite type of hot forming machine with a variety of easy to fix the size of the sheet clamping equipment. Some are all molding machines with a set of clamping structure.

2.Clamping equipment can be divided into two categories: one is structural, and the other is split. The structural clamping device is composed of two structures, upper and lower. The sheet is sandwiched between the two constructions. When the structure is opened, the lower structure usually adheres to the fixed condition. The lower part of the structure on the various types of single-station molding machines is directly fixed on the molding chamber. Manual and semi-automatic molding machines for hand-loading parisons and finished products are equipped with safe operation equipment within the scope of structural opening when the structural scale is large. For the forming of large slip billet,RequirementsThe clamping force can be adjusted in a relatively wide range. For this reason, two coated rollers are selected, pressed against each other with a tension spring, and equipped with a pressure conditioning device. The clamping of the continuous pull tab forming machine is the common effect of the zipper on both sides and the front and rear brakes.
The clamping equipment is best selected for automatic control, in order to move quickly, can contribute to the quality and power of the advanced parts.
2. heating equipment
Vacuum of Thermoplastic Sheet and FilmBlister moldingMachineProcess, one of the first processes is sheet heating. The duration and quality of electric heating depends on the structure of the heater, the thermal inertia of the temperature heat transfer after the radiation 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 data. Commonly used heaters are electric heaters, crystal radiators and infrared heaters.
3. vacuum equipment
The vacuum system is composed of vacuum pump, gas storage tank, valve, pipeline and vacuum gauge. In vacuum forming, a separate type of vacuum pump is often selected. The vacuum degree of this pump should reach0.07~0.09 Mpa(520mmHg) above. The gas tank is usually 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. On the vacuum line, it is necessary to have appropriate valves to control the vacuum narrow capacity.
The rolling power of the vacuum pump is determined by the size of the molding equipment and the molding speed, and the equipment with larger or faster molding speed is often as large2-4KW. The vacuum base system is based on the detailed production and development of the factory.RequirementsAnd set.
4. compressed air equipment
The pneumatic system can be composed of the molding machine itself with a compressor, a gas tank, a main road set in the workshop, a valve, etc. Molding machine requiredToThe pressure is0.4-0.5MPa compressed air, a variety of vacuum blister molding machine widely used piston air compressor. It can also be supplied with large spiral air compressors throughout the plant.
In addition to a lot of compressed air should be formed, there is also a part of the power used for demoulding, external cooling of the initial finished product and operation of the mold structure and working sheet.
5. cooling equipment
In order to produce power ahead, vacuumBlister moldingMachineThe finished product often needs to be cooled before demoulding. The ambitious situation is that the inner and outer surfaces of the workpiece and the mold are cooled, and the mold with internal cooling coils is the best choice. About non-metallic molds, such as wood, plaster, 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 appearance of the vacuum plastic forming parts.
If natural cooling is selected in production, annealed parts can be obtained, which is conducive to the impact resistance of the forward parts. Of course, water cooling produces high power, but the internal stress of the parts is large.
6. Demoulding Equipment
Demoulding is to remove the finished product from the mold. Usually, whether it is a concave mold or a convex mold, most occasions are due to the cooling shrinkage of the finished product and close to the mold, so the finished product is demoulded by vacuum attracting holes or blowing in the opposite direction.
Especially for molds with small demoulding inclination or concave mold, the demoulding tissue nozzle or vibration demoulding is used together, and sometimes the demoulding agent is altered on the sheet and mold or the surface of the mold is sprayed with Teflon.
7. Control Equipment

The control system usually includes vacuum blister forming.TypeThe process of finishing includes the control of various parameters and actions of instruments, meters, pipelines and valves. Control methods are manual, electrical-Mechanical automatic control, computer control, etc., the detailed selection should be based on the start of capital labor costs, technology.RequirementsThe cost of materials, the cost of production and repair equipment and other elements are summarized.
