Code for operation of bottle blowing machine
(1) Before each shift starts, each moving part must be lubricated once. (manipulator, manipulator guide rail, mold opening and closing guide rail)
(2) Swing arms can be added once every (3-4) days. The big chain and the small chain of the heater can be used once a month. Always check whether the main engine reducer and heater reducer are short of oil. The main engine bearing can be added once every 3 months.
(3) Before leaving the factory, check whether the moving parts are firm, whether the screws are loose and fall off, especially where the impact force is strong, and whether the belt transmission part is abnormal.
(4) Check whether the high-pressure air source, low-pressure air source, power supply and water source are normal.
(5) Check whether the emergency stop switch, emergency switch and protection device detection switch are normal.
(6) Check whether the embryo feeding and embryo dropping parts of the heating head work normally. If the blank is not inserted in place, the nut of the material pressing device can be adjusted.
(7) Check whether the lamp tube is damaged or broken. It should be replaced in time.
(8) Check whether the pneumatic components are leaking and whether the action is sensitive.
(9) Check whether the triplet is abnormally leaking and blocked, and whether the water storage capacity of the water cup is too full.
(10) When the solenoid valve of the automatic bottle blowing machine is abnormal, it should be cleaned in time.
The working principle of bottle blowing machine is mainly divided into three categories: extrusion bottle blowing machine, injection bottle blowing machine and special structure bottle blowing machine. The processing technology is mainly divided into one-step method and two-step method. One-step and two-step bottle blowing machine molding process is mainly used for the molding of PET and BOPP hollow containers. Both have their own characteristics and are widely used. Comparatively speaking, the two-step method is more suitable for centralized production of bottle blanks and decentralized bottle blowing; One-step equipment is more suitable for online production of beverage enterprises. The blowing program of the bottle blowing machine mainly includes six steps: 1) First, put the heated plastic embryo into the mold; 2) mold locking with a mold locking cylinder; 3) locking the blank mold with high pressure or mechanical structure; 4) pre-blowing at medium and high pressure, and simultaneously stretching the cylinder to expand the blank mold; 5) high-pressure blow molding, wherein the bottle blank is molded according to a mold, and the pressure is kept for a certain time; 6) Release the high pressure in the molding bottle and reset the gas bottle-take the bottle.
Pneumatic equipment is widely used in the operation of bottle blowing machine; From discharging-locking-stretching-high pressure blowing-deflation-bottle taking, this series of actions are all assisted by pneumatic equipment. For example, according to Figure 2, we can see that the gas path is divided into two parts, the normal pressure part and the high pressure part.
In this system, Delta pneumatic products can greatly improve the atmospheric part of the system. We recommend Delta pneumatic series equipment: 1) Solenoid valve: Delta YSVF3000\5000 series. Its characteristics are: large flow of solenoid valve; Long service life-more than 50 million times; The pilot adopts double air intake structure, which has strong environmental resistance; Beautiful appearance. 2) Cylinder: Delta YCA3 series; Vat YCS 1 series, YCQ2 series and YMB series; Rodless cylinder (open door cylinder): YPL series; Swing cylinder: YMSQ series. It is characterized in that the dynamic sealing ring of the cylinder is changed into PPD sealing ring structure in view of the high speed and poor use environment of the bottle blowing machine, and this sealing ring will automatically compensate after being subjected to gas pressure at high speed, thus reducing the contact pressure between the sealing ring and the cylinder wall and prolonging the service life of the cylinder. 3) Air claws: YCHB series, YCHA series. It is characterized by complete varieties, high quality and high cost performance. 4) filtration part: YAC series; YAFF and YAMG series products. Its characteristics are: low power, energy saving and environmental protection, and long service life of products.
