The interior bottom fixedly connected with controller 15 of storage case 3, controller 15 is connected with electric putter 8 and first range sensor 14 electricity respectively to realize that first range sensor 14 passes through the promotion and the stopping of controller 15 control electric putter 8. A trigger warning device 18 is fixed on the upper surface of the outer box body 1; the controller 15 is electrically connected with the second distance measuring sensor 16 and the warning device 18 respectively, so that the second distance measuring sensor 16 controls the warning device 18 to warn.

As shown in fig. 1 and 4, the application process of the application device is as follows: (1) putting the paint 17 into an upper storage box of the storage box 3; the film 19 is then passed through the opening 2 on one side of the outer housing 1, placed on the applicator roller 5 and passed through the opening 2 on the other side. When the paint is applied, the film is pulled, the film 19 drives the applying roller 5 to roll, and the rolling applying roller dips the paint in the storage box 3 and applies the paint on the lower surface of the film. After the coating is dried, a coating can be formed on the surface of the film 19.

(2) In the smearing process, the paint in the storage tank 3 is continuously reduced, the liquid level of the paint 17 is lowered, and the floating block 62 is lowered along with the liquid level; the descending floating block 62 pulls the connecting rope 10, and the connecting rope 10 drives the indicating block 91 to move upwards. When the distance between the first distance measuring sensor 14 and the indicating block 91 is equal to the set minimum value, the controller 15 opens the electric push rod 8 to push the support plate 7 to move upwards, so that the liquid level of the paint 17 moves upwards to meet the requirement of painting. When the distance between the first distance measuring sensor 14 and the indicating block 91 is equal to the set maximum value, the controller 15 closes the electric push rod 8 to stop the liquid level rising, so that the liquid level height of the paint in the material storage box 3 is always kept within the set range.

(3) The support plate 7 intermittently moves upwards due to the continuous drop of the coating liquid level; when the height of the supporting plate 7 rises, the distance between the supporting plate 7 and the second distance measuring sensor 16 is equal to the set maximum value; through controller 15 control warning device 18 warning, operating personnel sees or hears the warning back, can add coating 17 and control electric putter 8 to descend in storage case 3, can avoid the emergence of the too little condition of coating in storage case 3 like this.
