Defined by soft rubber pad printing head transfer plate on the graphic area ink to printing machine on the substrates.Pad printing machine is one of the important indirect printing patterns.
Power source:
The main action moving printing machine can be divided into: dip in with glue head down take pad printing ink and elevate plate;Above rubber head moves to substrates;Rubber pad printing head down after printing service.Three kinds of control model of the main action of different determines the three basic categories: moving printing machine
Manually moving printing machine, three kinds of movements are manual to control.Is the most simple moving printing machine, can complete the production of small orders and products proofing task.
Electric pad printing machines, three kinds of actions are motor drive and control.Printing speed is fast, but the printing pressure is small, can only complete the smaller area of production date and pad printing bar code products.
Pneumatic pad printing machines, three kinds of movements are digital circuit control of pneumatic components.Printing speed, pressure big, high degree of automation, is currently the most common moving printing machine.
Ink mode:
Now for the ink pad printing machine mainly include oil roller or painting in the reciprocating movement of the oil pan and plate above open ink system;Oil cup close the ink pad printing plate printing area and buffer area of the reciprocating closed for two kinds of ink system: the former is called oil disc pad printing machine, which is called oil cup pad printing machine.Oil disc pad printing machine can be used for solvent ink pad printing, screen printing ink and UV pad printing ink.In the use of solvent ink pad printing and screen printing ink, because the ink in the opening of the oil pan, direct contact with air, ink contained harmful ingredients can cause personal injury to evaporate into the air.Ink printing eligibility will occur fluctuations.Oil pan pad printing machine is the most common moving printing machine.
Oil cup pad printing machine is mainly used on printing ink and printing ink solvent.Ink within the oil cup will closed the harmful composition in isolation from the ink of volatile, operation staff's health damage to a minimum, guarantee the stability of the printing eligibility.But because the oil cup continuous sliding friction requirements of oil cup and pad printing plate between the height of the contact resistance and abrasion resistance, oil cup pad printing machine manufacturing difficulty is quite high.
The workbench types: fixed, mobile and back, wheel mobile, linear conveyor, stationary
Fixed worktable can adjust the location of the three-dimensional direction, mainly used in monochrome printing machine.This kind of workbench generally contain T slot structure, facilitate clamping fixture and products to ensure accurate printing.Fixed worktable and other type of architecture that prop up of workbench.
Shuttle, moving workbench is on stationary worktable can stay in a different position of shuttle form.Shuttle is combined with cylinder, according to the requirement of the sensor has a different position limits.Two-color shuttle workbench has two shuttle position limits, in double color pad printing machine;Four-color shuttle table has four shuttle position limits, in four color pad printing machine.In the operating process of the polychromatic pad printing machine, weaving machine stop position installed on the shuttle table on the basis of the digital circuit to control the electromagnetic sensors.Shuttle table for the location of the repeat precision is higher, so high accuracy.But through a table can only put a product, the production efficiency is low.
Rotary mobile worktable, is composed of the stationary worktable equipped with rotary table workbench.Rotary table can be moved to the specified location for printing when printed, because of wheel rotation cycle long, the repeat precision is poor, overprint precision turntable moving printing machine.But a rotary workbench can install 10, 16, 20 products, the production efficiency is higher.
Linear conveyor, conveyor linear table usually use above the pad printing machine of the high degree of automation, product with the conveyor belt conveyor, positioning, processing, printing, drying out.Straight line conveyor workbench with high accuracy and production efficiency, but architectural complex, there are only a few enterprises can produce.
Color: monochrome, two-color, multicolor, pad printing machine is a continuous printing chromatic number at most can be classified as a pad printing machine of another: one can only printing color pad printing machine called monochromatic moving printing machine, two colors is called double color pad printing machine, etc.Single color pad printing machine is a stationary worktable moving printing machine, the moving printing machine, if only an oil pan system, called the monochrome single head pad printing machine;If you have multiple sets of oil pan system is called a monochromatic bull moving printing machine.With two sets of oil pan system of moving printing machine equipped with shuttle workbench, become a dichroic shuttle pad printing machine;Equipped with rotary table, called double color wheel moving printing machine.So on.
