The invention discloses a novel adjustable silk screen tightening device. The novel adjustable silk screen tightening device comprises a supporting platform, and four rows of clamping devices are fixed to the top of the supporting platform correspondingly in the four directions. Each clamping device comprises a sliding base and a sliding table, wherein a torque motor is disposed behind the slidingtable and fixed to the sliding base; a screw rod is coaxially fixed to an output shaft of the torque motor; a screw hole is formed in the sliding table; a pressing rod is hinged to the upper portionof the middle of the sliding table and provided with a sliding groove; an adjusting screw rod is disposed in the sliding groove and provided with adjusting nuts which are located on the two sides of the pressing rod correspondingly; an upper clamping jaw is fixed to the outer end of the adjusting screw rod; a lower clamping jaw is fixed to the front portion of the sliding table; a driving rod is hinged to the lower portion of the middle of the sliding table; and the middle of the driving rod and the middle of the pressing rod are both hinged to a connecting rod. The novel adjustable silk screen tightening device can rapidly clamp a silk screen and then tighten the silk screen, the clamping positions of the clamping devices for the silk screen can be individually adjusted after the silk screen is tightened, and the tightening effect of the silk screen is improved.
Description
technical field [0001] The invention relates to a novel wire mesh tensioning device which can be adjusted. Background technique [0002] The full name of the screen printing machine is "screen printing machine". It is a kind of equipment that prints solder paste or patch glue onto the PCB pad through the screen. It can be divided into vertical screen printing machine, oblique arm screen printing machine, and turntable screen printing Machine, four-column screen printing machine and automatic screen printing machine, mainly used in the electronic processing industry, printed circuit board silk screen logo, instrument shell panel logo, solder paste printing in the process of circuit board processing, etc. Before the wire mesh is used, it needs to be tightened and fixed on the frame before it can be used in the wire mesh machine. At present, there is no special tensioning device for the wire mesh. Contents of the invention [0003] In view of the above problems, the present ...
