Description
Technical field:
The present invention relates to circular screen printer technical field, in particular to a kind of magnetic force adjusting of circular screen printer stamp magnetic platform.
Background technology:
The scraer printing system of circular screen printer is divided into blade to scrape and magnetic bar printing two kinds of forms.It is that elasticity by stainless steel blade itself applies pressure that blade scrapes, and the feature of printing is that to scrape lines more clear, but adapts to the kind of fabric and being limited in scope of fabric width, is unsuitable for thick and heavy and fabric that is wide cut.Magnetic bar printing is in cylinder, put a rod iron, is provided with row's magnet below fabric, rod iron by attraction thus to mill base apply pressure complete stamp.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, and therefore range of application is further extensive.
Magnet below magnetic rod type cylinder printing machine fabric is divided into permanent magnetic iron and electromagnetism magnetic platform two kinds, can adjust its suction to bar magnet for permanent magnetic iron by the distance changed between magnet and bar magnet.As shown in Figure 1, the magnetic force adjusting of circular screen printer stamp magnetic platform, wherein, the magnet in described stamp magnetic platform 11 adopts permanent magnetic iron.The operation principle of magnetic force adjusting described in Fig. 1 is as follows: the cylinder component 20 be arranged on bottom magnetic platform supporter 10 drives the central shaft 21 be connected with its piston to stretch or shrink, the bottom that the top of central shaft 21 acts on rocking arm 30 rotates a certain angle to drive rocking arm 30, be articulated in rocking arm 30 top on magnetic platform supporter 10 by magnetic platform 11 jack-up or certain distance that declines, to change the distance between magnetic platform 11 and bar magnet.By above-mentioned magnetic force adjusting, circular screen printer in operation, can adjust the size of magnetic platform magnetic force according to the thickness of different printcloth and material, thus reaches best printing quality.
Summary of the invention:
Technical problem solved by the invention: in prior art, the magnetic force adjusting of circular screen printer stamp magnetic platform, by the flexible size adjusting magnetic platform magnetic force of central shaft be connected with cylinder component piston, the Adjustment precision of its magnetic platform magnetic force has much room for improvement.
For solving the problems of the technologies described above, the invention provides following technical scheme:
A magnetic force adjusting for circular screen printer stamp magnetic platform, comprise be arranged on the cylinder component bottom magnetic platform supporter, the central shaft be connected with cylinder component piston, middle part are articulated in rocking arm on magnetic platform supporter; The bottom of described rocking arm is connected with central shaft, and the top of rocking arm is connected with the magnetic platform on magnetic platform supporter;
The magnetic force adjusting of described circular screen printer stamp magnetic platform also comprises the gear-box be fixedly mounted on side rail outer wall, the gear train be arranged in gear-box, the drive link be connected with driving gear in gear train, the adjustment screw rod that is connected with driven gear in gear train; Described side rail inner wall is installed with supporting seat, supporting seat accepts magnetic platform supporter, described driven gear centre offers screwed hole, and one end of adjustment screw rod is screwed onto in the screwed hole of driven gear, and the other end of adjustment screw rod passes curb girder and pushes up the bottom to rocking arm; The bottom of described supporting seat is provided with the internal thread block to downward-extension, and the other end of described adjustment screw rod is provided with external screw thread, and the other end and the internal thread block that are provided with externally threaded adjustment screw rod are spirally connected; Described adjustment screw rod and central shaft are positioned at the both sides of rocking arm bottom.
