Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laminating screen plate, in particular to a composite laminating screen plate mechanism. BACKGROUND

[0002] The laminating screen plate mechanism is usually a mechanism used on a screen plate laminating machine for attracting a film body and laminating it with a laminating object. An automatic screen plate laminating machine is disclosed in Chinese Patent No. CN215283861U, which comprises a rack, a turning plate assembly, a horizontal laminating assembly, and a control part. The turning plate assembly is arranged at one end of the rack and can rotate in the rack. The horizontal laminating assembly is arranged at the other end of the rack and can move to the lower side of the turning plate assembly during work. The control part is electrically connected with the turning plate assembly and the horizontal laminating assembly. The mechanical attachment operation replaces manual attachment by workers, overcomes the problem of poor attachment quality caused by uneven force and hand shaking during operation, and is beneficial to ensuring the quality and efficiency of attachment and improving enterprise efficiency. Moreover, the mechanical attachment operation can work for a long time, which is beneficial to reducing labor costs and avoiding the emergence of safety hazards caused by fatigue during attachment, and is beneficial to improving the safety factor.
