[0055] Base material flat material component 3: Figure 1 , two As shown, at the unloading place of the base material device 1, a base material leveling component 3 is provided to realize the base material leveling.

[0056] The main forms of the base material leveling component 3 are: the width adapts to the width of the trolley 6, the front end of the leveler is designed with a leveling tooth group, and the mechanical structure and reciprocating motion are used to achieve further leveling of the material; the rear end of the leveler is designed with a leveling brush group, and the mechanical structure is used to reciprocate and brush the already relatively uniform base material to achieve further leveling of the material.

[0059] Level meter group 5: Figure 1 , three As shown, N laser rangefinders are designed to measure the material thickness of the trolley 6. The value of N is determined according to the number of auxiliary doors of the trolley 6 to complete the real-time measurement of the material thickness and then adjust the material thickness.

[0060] Main parameters of laser rangefinder: two-wire 4~20mA DC, response time less than 30ms.
