The bottle blowing machine is mainly used for the production of liquid packaging containers. The entire bottle blowing process requires the cooperation of auxiliary equipment to complete the bottle blowing work. Common auxiliary equipment includes high-pressure air compressors, low-pressure air compressors, chillers, cooling towers, cold dryers, mold temperature controllers, filters, gas recovery storage tanks and other auxiliary equipment. How do these auxiliary equipment work? What are their functions? Today, we will explain the auxiliary equipment and functions of bottle blowing machine in pictures and texts.
Low-pressure air compressors: The low-pressure air compressors commonly used in bottle blowing machine auxiliary equipment are mainly piston low-pressure air compressors, screw low-pressure air compressors, and piston low-pressure air compressors. Free gas is used as a piston to compress the gas and then discharge the gas. The screw compressor is a rotary positive displacement compressor, in which two rotors with helical gears mesh with each other to compress and discharge the gas. Compared with the piston low-pressure air compressor, it runs smoothly and safely, is energy-saving, and is automatically adjustable. Tengyue bottle blowing machine manufacturers all use low-pressure screw air compressors
Function: pre-blowing and low-pressure bottle blowing, and high pressure bottle blowing to ensure one-time bottle forming rate.
High-pressure air compressor: mainly composed of compressor host (excluding gas storage tank), motor, interstage cooler, air separation and purification device, etc. The gas sucked into the tank body is compressed in three levels and then separated, filtered and purified to purify the odorless high-pressure air.
Function: compress the air in the free state into clean and odorless high-pressure gas, blow the preform at high speed, and form the bottle in one time.
Blowing machine chiller:
Chillers are mainly divided into water-cooled and air-cooled types. The characteristics of water-cooled chillers are: ergonomic panel, fully automatic control, equipped with precision electric temperature controller, long-term stable operation; using high-efficiency heat transfer heat exchanger, less cold loss, easy oil return, heat transfer tube will not freeze and crack; using imported high-performance compressors, high EER value, low noise, stable operation. The characteristics of air-cooled chillers are: no need to install cooling towers, easy to install, easy to move, suitable for occasions where water sources are lacking and no need to install water towers; low-noise fan motor, excellent cooling and condensing effect, stable throttling structure, excellent anti-rust treatment; imported high-performance compressors, high EER value, low noise, stable operation.
Function: Rapidly cool the water, cool the blow molding machine mold, protect the blow molding machine mold, and quickly cool the product to improve the product and quality. Tengyue blow molding machine manufacturers generally recommend customers to use air-cooled blow molding machines
Blow molding machine cold dryer: It is composed of a refrigeration compressor (the heart of the refrigeration system), a condenser, an evaporator, an expansion valve, etc., and uses refrigerant to exchange heat with compressed air to reduce the compressed air temperature to a dew point temperature in the range of 2 to 10°C. And cooperate with filters to filter the moisture and oil in the air, so that the products produced are oil-free and the quality of the products is improved.
Filter: The main function is to filter out waste such as oil, water, impurities, etc. contained in the compressed air and work with the cold dryer.
Mold temperature controller: also called mold temperature controller, originally used in the temperature control industry of injection molds. Later, with the development of the machinery industry, it was used more and more widely. Now the temperature controlled by the mold temperature controller is generally divided into water temperature controller and oil temperature controller, which can reach plus or minus 0.1 degrees.
Blowing machine mold temperature controller: mold temperature controller is also called mold temperature controller, hot filling blowing machine auxiliary equipment, it plays the role of controlling the temperature of the mold, keeping the temperature of the mold constant, so as to ensure the stability of the production quality of blowing bottles.
Blowing machine air recovery system: the recovery system and gas storage tank are composed of high pressure and low pressure recycling and reuse, reducing energy consumption, and saving 25% of low pressure gas.
