How to choose the suitable film blowing machine? As well as the boot before the note!

How to choose the suitable film blowing machine? As well as the boot before the note!

  Film blowing machine and is machine width, film blowing machine GB model points to 600mm, 800mm, 1000mm, 1100mm 1500mm, 1800mm, 2000mm, machine width is not the same as they film blowing range is not the same, the machine width is not the same as the price difference is very big. So the customer should first choose the machine saw their own products the largest width is how much.

  Limit down to blow machine that will be able to cast the least money to buy the most suitable for the machine, can not be blind pursuit of large machines, for example, many customers want to buy machines that may need to do more wide film, it is not, because you are currently doing relatively narrow, for example, you use 1.5 meters of 600mm membrane that is like anti-aircraft guns to fight mosquitoes overkill, the temporary step said this practice costs increased electricity greatly increased the cost-effective, can make products will lose money, but also can not choose small machine big products, because the machine can't do, to choose the film confidential choose appropriate oneself, aware of their products is how.

  Note pressure blowing machine

  The operator when operating the machine can not stand in front of Yu Zheng, in order to avoid accidentally hurt the operator. When the feed to prevent hard objects falling into the barrel of raw materials with metal impurities and the damage to the machine tools operation. The operation of rotating machinery is prohibited with gloves, in case of injury.

  Within the range of the film blowing machine conditions, improving the forming temperature, cooling air temperature and blow up ratio; then the turbidity of the film increases, gloss reduced; on the contrary, increasing.

  3 boot operation must first check the various power wiring is disconnected and leakage; check whether the instruments damage is not normal. Before starting to ensure the safety of the various parts of the normal, so as not to affect the production and cause accidents.

  The inspection and good speed reducer, lubricating oil in the air compressor, check the lubrication of mechanical transmission components. To avoid the drying up of machines and make noise.

  The die outlet uniform, can wear gloves slow lifting tube, and the tube billet end closed, ajar inlet regulating valve to from the center hole of the mandrel to add a small amount of compressed air, and carefully lighted foam frame, lambdoidal board, and penetrates into the traction and, guide roll until coiling (for example, embossed to pass embossing roll)

  Blow the expansion tube compressed air pressure should be appropriate, neither the tube rupture, but also to ensure the symmetric stabilization of the membrane tube, relative to ensure the quality of the production.

  But clear squeeze machine and die can use copper knife, a stick or compressed air to clean up the, but avoid damage the screw rod and the screw surface finish.

  Before starting the preparations and precautions:

  1, power supply, electrical parts inspection, all parts should be safety grounding.

  2, the material requirements should be dry, otherwise it should be pre drying.

  3, check whether the installation work according to the requirements of the installation, check the bolts of good.

  4, the material does not fill the plastic tube, filled with plastic and temperature does not meet requirements, prohibit.

  5, check the material can not be a foreign body, raw materials shall not have iron or other undesirable materials are mixed with.

  6, check and add a good reducer, air compressor lubricating oil, check the lubrication of the mechanical transmission parts.

  7, check the unit heating system and temperature measurement system in good condition.

  8, the boot process, irrelevant personnel should leave, to prevent local overheating of the material out of the burn, to prevent the belt and a mixing barrel stabbed, to prevent hair, clothing is rolled inside to get it.
