10. A construction method of a material preparation device for preventing the surface of wall putty from foaming is characterized by comprising the following steps:

firstly, proportioning raw materials, namely adding a certain amount of powder raw materials such as putty powder into a powder box, weighing the added powder raw materials by a pressure sensor at the moment, transmitting an electric signal to a PLC (programmable logic controller) through a wire, controlling the output end of a liquid level pneumatic cylinder to move downwards by the PLC according to a set proportioning value, driving a baffle to move downwards by the output end of the liquid level pneumatic cylinder, introducing non-pressure solution raw materials such as water, an auxiliary agent and the like into a water inlet plate at the moment, flowing the solution raw materials into the liquid box through an L-shaped water channel at the moment, driving water to float upwards to block the L-shaped water channel after the liquid level moves upwards, and then automatically measuring;

secondly, feeding and stirring, wherein a driving pneumatic cylinder is opened, the output end of the driving pneumatic cylinder drives a transmission rod to slide in an annular frame, the annular frame drives a turnover plate to rotate around the hinged position of the turnover plate, the powder raw material directly falls into a mixing barrel, a liquid level pneumatic cylinder is opened, the output end of the liquid level pneumatic cylinder drives a baffle to reset and move upwards, a solution flows into the raw material mixing barrel, a driving motor is opened, the output end of the driving motor drives a rotating shaft to rotate through a gear, the rotating shaft drives a stirring rod to stir the raw material, the raw material is stirred for ten minutes at the rotating speed of one hundred and two revolutions per minute and then is kept stand;

and thirdly, discharging, rotating the threaded rod, driving the material baffle plate to move outwards by the threaded rod, enabling the finished putty to flow into the material discharging box at the moment, starting the discharging motor, driving the auger to rotate by the output end of the discharging motor, driving the finished putty to move out of the mixing barrel by the auger, starting the first hydraulic cylinder and the second hydraulic cylinder, moving the driving pipe downwards and pushing the first sliding ring downwards, moving the scraping head downwards along the motion line of the spiral line, scraping the putty on the inner wall of the mixing barrel, and transporting the residual putty to the outside of the mixing barrel through the auger to complete discharging.
