Novel adjustable silk net clamping device

Abstract

The invention discloses a novel adjustable silk net clamping device comprising a sliding base and a sliding table. A moment force motor is arranged on the rear portion of the sliding table, a screw iscoaxially fixed to an output shaft of the moment force motor, and a screw hole is formed in the sliding table. A pressing rod is hinged to the upper portion of the middle of the sliding table, a sliding groove is formed in the pressing rod, and an adjusting screw is arranged in the sliding groove. The sliding groove is perpendicular to the adjusting screw, the positions, on the two sides of the pressing rod, of the adjusting screw are each provided with an adjusting nut, and an upper clamp claw is fixed to the outer end of the adjusting screw. The front portion of the sliding table is fixedlyprovided with a lower clamp claw matched with the upper clamp claw, a driving rod is hinged to the lower portion of the middle of the sliding table, and the middles of the driving rod and the pressing rod are each in hinged connected with a connecting rod. A baffle is fixed to the position, in front of the sliding table, of the sliding base, and a buffering layer is fixed to the inner side of thebaffle. According to the novel adjustable silk net clamping device, a silk net can be rapidly clamped, then tightening operation is conducted, and after tightening, the clamping position of one certain clamping device body for the silk net can be adjusted, so that the tightening effect of the silk net is improved.

Description

technical field [0001] The invention relates to a novel wire mesh clamping 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 to the frame before it can be used in the wire mesh machine. At present, there is no special clamping device for wire mesh tensioning. Contents of the invention [0003] In view of the above problems, the prese...
