Abstract
The invention relates to the technical field of flat screen printing equipment and provides a scraper device of a treadmill flat screen printing machine. The scraper device comprises a tool rest; two scrapers are arranged in parallel on the inner side of the tool rest; the upper parts of the two scrapers are hinged together through two connecting rods; the two connecting rods are fixedly connected through a cross beam. During a forward stroke, under the driving force of a scraper driving device, a multi-wedge conveyor belt drives the cross beam to drive the two scrapers hinged together through the two connecting rods and the tool rest to slide axially along a polish rod on a tool rest frame, so that the two scrapers can simultaneously carry out printing operation to a piece of fabric; during a return stroke, residual dye is collected to an initial position so as to facilitate a printing operation next time; according to the actual requirements of the printing process, the two scrapers can be controlled to perform secondary scraper printing to a silk screen by adjusting a scraper angle adjusting device. Therefore, not only is the printing quality of the fabric ensured, but also the printing efficiency is improved.

The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
The doctor blade device of the treadmill flat screen printing machine that the embodiment of the invention provides comprises knife rest, and the inboard of this knife rest walks abreast and is provided with two scrapers, and the top of two scrapers is hinged by two connecting rods, and these two connecting rods fixedly install together by crossbeam.
Fig. 1 shows the structural representation of the doctor blade device of the treadmill flat screen printing machine that the embodiment of the invention provides, and for convenience of explanation, this figure only provides the structure division relevant with the present invention.
The doctor blade device of treadmill flat screen printing machine comprises knife rest 1, knife rest 1 is slidingly arranged on the knife rest frame of treadmill flat screen printing machine, the inboard of knife rest 1 walks abreast and is provided with two scrapers 2, the top of two scrapers 2 is hinged by two connecting rods 3, two hinge bars 3 fixedly install together by crossbeam 4, and the two ends of crossbeam 4 are fixedly installed on respectively on many wedges conveyer belt of scraping driving device for cutter on the treadmill flat screen printing machine.Before the work, dyestuff is being poured between two scrapers 2, during process, scrape under the driving of driving device for cutter, many wedges belt-driven crossbeam 4 drives two scraper 2 and knife rest 1 the endwisely slipping along feed rod knife rest frame on hinged with connecting rod 3, thereby make two scrapers 2 carry out the stamp operation to fabric simultaneously, during backhaul, being positioned at one of back along its traffic direction collects initial position to scraper 2 with remaining dyestuff and is convenient to stamp next time, both guarantee the printing quality of fabric, improved the efficient of stamp again.
In this embodiment, traffic direction along knife rest 1, the front portion of knife rest 1 and rear portion all are fixed with scraper angle adjusting device 5, scraper angle adjusting device 5 comprises the fixed head 51 that is fixedly set on the knife rest, fixed head 51 is provided with screwed hole, screwed hole has been threaded and has regulated bolt 52, regulates bolt 52 and refers to that scraper 2 is so that regulate its operating angle.After using this kind scraper angle adjusting device, the operating angle of two scrapers 2 all can be according to demand of practical production at different products or printing quality requirement, regulate the adjusting bolt 52 of both sides respectively, control two scrapers 2 when process and the operating angle during backhaul, so the pressure of regulating its silk screen in 2 pairs of screen frames of scraper when the process quality of controlling stamp with and when excess dye is collected in backhaul, whether silk screen is carried out secondary and scrapes.
