The invention discloses an adjustable silk screen tensioning device which comprises a supporting platform. Four rows of clamping units are fixed to the top of the supporting platform in four directions correspondingly. Each clamping unit comprises a sliding base and a sliding table, wherein an air cylinder is arranged behind the sliding table, a pressing bar is hinged to the upper portion of the middle of the sliding table, a sliding groove penetrating through the pressing bar is formed in the pressing bar, an adjusting screw in clearance fit with the sliding groove is arranged in the slidinggroove, and the sliding groove is perpendicular to the adjusting screw; adjusting nuts are arranged in the positions, on the two sides of the pressing bar, of the adjusting screw; and an upper clamping jaw is fixed to the outer end of the adjusting screw, a lower clamping jaw matched with the upper clamping jaw is fixed to the front portion of the sliding table, a drive bar is hinged to the lowerportion of the middle of the sliding table, and a connecting rod is hinged to the middle of the drive bar and the middle of the pressing bar. According to the adjustable silk screen tensioning deviceprovided by the invention, a silk screen can be fast clamped tightly, accordingly, tensioning operation is performed, the tensioning positions of the silk screen by particular clamping units can be adjusted after tensioning is completed, and the tensioning effect of the silk screen is improved.
Description
technical field [0001] The invention relates to an adjustable wire mesh tensioning device. 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 invention provid...
