The Study Of Automatic Screen Printing Machine Based On Segmented Transmission

With the expansion of the clothing market, the silk screen printing technology is widelyused in garment printing. Traditional silk screen printing has many disadvantages such asstation is too small、positioning accuracy is low、the transmission accuracy is low、operationis not convenient and printed on baking is not sufficient. In this condition, the arctic proposesa new automatic screen printing technology with high positioning accuracy、high productionefficiency and easy to operate. It is pay attention to transmission system, positioning systemand baking way. The main content can be listed as follows:Firstly, the transmission of traditional printing equipment is monolithic, which has muchdefect. This arctic designs a sectional drive system, which divides the monolithic transmissioninto many parts. Analyzes the motion systems and creates corresponding model simulation.The movement devices could run sequentially and achieve the purpose of transmission forplaten, So it could be ensure the stability of the movement but also improve the transmissionaccuracy of the silk screen printing machine.Secondly, designs a new positioning device by five points. The edge of the platencontacts with five steel balls in printing station. Two balls are embedded in the network andthe others are embedded respectively in left positioning block、front positioning block and theright positioning block. The platen can be fixed under the screen frame, which could beadjusted by multi-adjustable device. So this positioning device could improve the accuracy ofprinting but also be convenient to operate.Thirdly, proposes a baking principle of the multi-layer equipment, which would offer acontinuous baking for fabric. And then the theories of operation are analyzed in details. Themultilayer drying device has two parts, which the speeds of them are the same but in theopposite direction. The platen moves from down to up in one part, and then from up to downin the other part by the help of push plate mechanism. Moreover, the temperature of oven andthe speed of platen can be set according to the actual situation, which could achieve thepurpose of energy-saving.The prototype has been produced by the cooperation between the research and enterprise,and the practice has proved that the method and the result are reasonable. This prototype hasmany advantages such as high efficiency, high transmission precision and so on.
