Abrasive paper printing and water feeding mechanism

Abstract

The invention provides an abrasive paper printing and water feeding mechanism. A first bottom transitional roller and a second bottom transitional roller are installed on the bottom layer of a machineframe. Vertical pillars are fixed to the machine frame, and a plurality of supporting cross beams are installed between the vertical pillars. Water grooves are installed in the supporting cross beamsin a supporting mode. A pedestal is fixedly installed at the tops of the vertical pillars. A water roller spindle is installed on the pedestal, and a water roller is installed on the water roller spindle. An extrusion roller spindle is installed at the upper end of the water roller spindle, and an extrusion roller is installed on the extrusion roller spindle. The extrusion roller spindle is installed on a slippage block in a supporting mode. The top of the slippage block and a threaded hole in the middle of a top plate are in threaded transmission fit through a vertical screw rod. A hand wheel is installed at the top of the vertical screw rod. A spring is installed between the slippage block and the water roller spindle. According to the installation and adjustment mechanism, the mode that the water grooves are used for fixing to adjust the height of the water roller is adopted to ensure contact between the water roller and water in each water groove.

Description

technical field [0001] The invention belongs to the field of sandpaper production equipment, in particular to a sandpaper printing and water supply mechanism. Background technique [0002] Sandpaper is usually made by sticking various abrasive grains on the base paper, and is used to grind the surface of metal and wood to make the surface smooth and clean. Before leaving the factory, it is necessary to print trademarks and patterns on the back of the sandpaper, which requires special sandpaper printing equipment, and one of the processes requires watering one side of the sandpaper. [0003] In CN107225852A, a kind of cashmere sandpaper printing machine is disclosed, but only parts such as the ink tank bracket and the ink tank are disclosed, and the water supply mechanism is not disclosed, and the traditional above-mentioned mechanism is to ensure that the squeeze roller contacts the water tank and water , it is necessary to adjust the height of the water roller. Due to the ...

Problems solved by technology

[0003] In CN107225852A, a kind of cashmere sandpaper printing machine is disclosed, but only parts such as the ink tank bracket and the ink tank are disclosed, and the water supply mechanism is not disclosed, and the traditional above-mentioned mechanism is to ensure that the squeeze roller contacts the water tank and water , it is necessary to adjust the height of the water roller. Due to the heavy weight of the tank filled with water, it is inconvenient to operate when adjusting its height, and in the process of adjusting the height of the tank, it may also cause the water inside the tank to spill. In addition, according to different For printing needs, it is also necessary to adjust the gap between the squeeze roller and the water roller, the traditional gap cannot be adjusted
