Description
Technical field
The utility model designs Weaving device, relates in particular to a kind of Magnetic Control device of magnetic rod type cylinder printing machine.
Background technology
The scraer printing system of circular screen printer is divided into blade and scrapes and two kinds of forms of magnetic bar printing.It is that elasticity by stainless steel blade itself is exerted pressure that blade scrapes, and the characteristics of printing are that to scrape lines more clear, but adapt to the kind of fabric and being limited in scope of fabric width, are unsuitable for thick and heavy and fabric wide cut.Magnetic bar printing is to put a rod iron in cylinder, be provided with row's magnet below the fabric, thereby rod iron is exerted pressure to finish stamp by attraction to mill base.The svelteness degree of magnetic bar printing is slightly poorer than blade and scrapes, but it almost adapts to the printing in textiles of all thickness and width, so range of application is further extensive.
Magnet below the magnetic rod type cylinder printing machine fabric is divided into two kinds of permanent magnetic iron and electromagnetic platforms: can adjust it to the suction of bar magnet by the distance that changes between magnet and the bar magnet for permanent magnetic iron; And the electromagnetic platform all adopts direct current supply, by special Magnetic Control circuit magnetic force is controlled adjustment, and its purpose is exactly to control the size of magnetic force by the power supply that changes solenoid.Existing Magnetic Control circuit as shown in Figure 1, mainly formed by transformer T, change-over switch K, rectification circuit Z and electromagnet R, the connection of the different electric pressures of transformer T output is realized the power supply adjustment of electromagnet R by change-over switch K, the method is the gear adjustment, can not evenly adjust smoothly magnetic force.
