Ball linkage pair composite passive heating structure

Abstract

The utility model discloses a kind of ball linkage pair composite passive heating structures, it includes envelope mounting plate, upper pressure film heat sealing structure, lower heating structure: the upper pressure film heat sealing structure and the lower heating structure are all installed on the envelope mounting plate by bolt, the upper pressure film heat sealing structure includes bolt installation on the envelope mounting plate locking plate, installation in the locking plate one side's sliding table air cylinder. Compared with prior art, by the setting of pressure film heat sealing structure, lower heating structure, rectangular spring and ball, the structure sets upper pressure film heat sealing structure and lower heating structure, the double-sided film coating of reaction cup can be realized, and heating temperature can be effectively controlled in film coating process to realize the uniformity of heating, and under the cooperation of multiple springs and ball, floating heating fixed block can be rotated, so that its heating surface and the film coating surface of reaction cup are closely adhered, the uniformity of adhering pressure is guaranteed to improve the film coating yield.
