Film pasting and bending mechanism

Abstract

The invention relates to a film pasting and bending mechanism. The film pasting and bending mechanism is characterized in that a bottom plate is connected with a suction plate seat plate; the bottom plate is provided with a front edge-folding device and a side edge-folding device which are capable of automatically and upwards foldingthe edge of a protection film; the suction plate seat plate is fixedly provided with a vacuum suction plate; a containing groove is formed in the middle part of the vacuum suction plate; a product locating and fixing block is fixedly arranged in the containing groove; the product locating and fixing block is movably connected with a product locating and moving block; air vents which are used for sucking the protection film are also formed in the vacuum suction plate; the suction plate seat plate is connected with locating pins which are used for assisting product location through elastic pieces a; the top ends of the locating pins stretch out from the vacuum suction plate. According to the film pasting and bending mechanism disclosed by the invention, the protection film is arranged on the vacuum suction plate and is located through the locating pins, and the protection film can be sucked by the vacuum suction plate; a back adhesive layer of the protection film can be torn off by hand, aproduct is placed on the protection film, the product can be pressed down through the matching of a pressing machine after locating, the edge of the product leans against the front edge-folding device and the side edge-folding device, the edge of the protection film can be automatically and upwards bent so as to coat the product, and the film pasting effect is good.
本发明涉及一种贴膜折弯机构,底板上连接有吸板座板,底板上设置有能够将保护膜自动向上折边的前折边装置和侧折边装置;吸板座板上固装有真空吸板;真空吸板中间设有容置槽,产品定位固定块固装在容置槽内;产品定位固定块上活动连接有产品定位活动块;真空吸板上还设有用于吸住保护膜的气孔;吸板座板上通过弹性件a连接着辅助定位产品的定位销,且定位销顶端从真空吸板上伸出。本发明将保护膜放置在真空吸板上,通过定位销定位,真空吸板吸住保护膜;手动撕掉保护膜的背胶层,将产品放置于保护膜上,定位后配合压合机构将产品下压,产品边缘抵持前折边装置和侧折边装置,将保护膜边缘自动向上折弯,包裹在产品上,贴膜效果好。
