10. A method of applying a casting machine for CPP film production as claimed in claims 1-9, characterized in that: the method comprises the following steps:

s1, distributing and stirring: firstly, powder raw materials, a binder, a plasticizer and a dispersing agent are arranged in a ratio of 3: 1 and are put into a feeding hopper, the powder raw materials pass through a feeding hole (4005) and fall into the tank body (4001), the output end of the first motor (4003) is driven to rotate at a constant speed by starting the first motor (4003), so that different powder materials in the tank body (4001) are mixed, the powder materials are stirred for 1-2 hours, and then a first electromagnetic valve (4006) is opened through electric signal transmission, so that the fully mixed powder materials fall into the bottom bin (4002);

s2, mixing the mixed solution: opening one of the second electromagnetic valves (5005) and the electric gate valve to enable mixed powder in the bottom bin (4002) to enter the interior of the rotary drum (5002) along the telescopic pipe (5004), opening the valve (5008) to enable one end of the second electromagnetic valve to be communicated with a solvent source, and adding a proper amount of solvent into the rotary drum (5002) to dissolve the powder, wherein the output end of the second electromagnetic valve drives one end of the telescopic pipe (5004) to perform telescopic movement by starting the second motor (5007) until one end of the telescopic pipe (5004) is attached to one side of the second electromagnetic valve (5005) to ensure the sealing property between the two, and then the output end of the second electromagnetic valve drives the rotary drum (5002) by starting the second motor (5007) to facilitate the mixing of the solution in the rotary drum (5002) to form slurry with a certain viscosity;

s3, homogenizing: after the step S2, the slurry enters the box body (6001) under the flow guiding action of the feeding pipe (6004), the box body is kept in a standing state to be homogenized, the slurry is subjected to water quality layering after 2-3 hours, and the viscous slurry flows to the discharging pipe (6003) until the viscous slurry is conveyed to the inside of the discharging pipe (6003) through the starting pump (6002);

s4, scraping, pressing and coating: uniformly discharging materials at the bottom end of the discharging box (7001), paving a layer of uniform slurry on the surface of the base band (1100), and turning the knob (7004) and adjusting the height of the scraper (7002) to scrape and rub the slurry by the scraper (7002) so as to form a primary thin film product with a specified thickness;

s5, hot air drying: the method comprises the steps that a base belt (1100) drives a film primary product to move to the bottom end of a wind box (8001) through the conveying function of a conveyor (100), and a fan (8004) is started, so that a preheated explosion-proof glass tube (8002) performs heat supply treatment, specified and stable hot wind is formed, and the film primary product is dried, wherein heating of an electric heating wire (8003) is controllable;

s6, quantitative cutting: s5, enabling the film primary product to be a green belt, drawing one end of the green belt to the top end of the material receiving platform (200), enabling the output end of the green belt to press the lifting plate (9002) through the starting cylinder (9004) until the bottom end of the cutter (9003) contacts one side of the green belt, and cutting the green belt, so that a CPP film product with a specified size can be placed at the bottom end of the material receiving platform (200);

s7, stacking and collecting: the CPP film products after being cut are stacked and reach the specified height, and then outer-layer packaging is carried out, so that the CPP film products are packaged into concentrated products in the specified quantity.
