Eternal Blister Machine: Composition and Function of Blister Machine

Today, I will tell you about it.The composition and function of the 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.
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 state. 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 of parisons and finished products are equipped with safe operating 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 rubber-coated rollers are selected, which are pressed against each other with tension springs, and are equipped with pressure conditioning equipment. The clamping of the continuous pull tab forming machine is the function of the two-end zipper and the front and rear brakes together.
The best choice of clamping equipment is automatic control, in order to move quickly, can contribute to the quality and efficiency of the forward parts.
2. heating equipment
Thermoplastic sheet and film vacuum molding process, one of the first process 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 accumulator shall be at least half the capacity of the largest forming chamber. On the vacuum line, it is necessary to have 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 often as large2-4KW. The size of the vacuum base system depends on the detailed production and development of the plant.RequirementsAnd set.
4. compressed air equipment
Pneumatic system can be composed of the molding machine itself with a compressor, gas storage tank, workshop main road set, valves, etc. The molding machine requires a pressure0.4-0.5MPa 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 advance production efficiency, the finished product of vacuum blister molding 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.
6. Demoulding Equipment
Demoulding is to remove the finished product from the mold. Usually, whether it is a concave mold or a convex mold, in most cases, the finished product is tightly attached to the mold due to cooling shrinkage, so it is demoulded by vacuum attracting holes or blowing in the opposite direction.
Especially for molds with small demoulding inclination or concave mold, the demoulding organization is used together to plug or vibrate demoulding, 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 the control of various parameters and actions of instruments, appearance, pipelines and valves in the process of vacuum blister molding and finishing. Control methods are manual, electrical-Mechanical automatic control, computer control, etc. The detailed selection shall be based on the labor cost and skills invested at the beginning.Requirements, material costs, production and maintenance equipment costs and other elements of inductive thinking.
