Tensile strength detection device for protecting film

Abstract

The invention discloses a tensile strength detection device for a protecting film. The tensile strength detection device for the protecting film structurally comprises a bottom plate, a supporting rack, a top plate, a mounting seat, a movable air cylinder, an air cylinder rod, a tension sensor, a clamping plate, a first spiral bolt, a tightening plate, a PLC, a button, a display screen, and a fixed plate rack adjusting and clamping structure, a protecting observation plate adjusting and shielding structure and a waste material storage box supporting structure. The bottom plate and the top plate are separately welded to the upper and lower ends of the supporting rack; the mounting seat is separately mounted on the left and right sides of the upper surface of the top plate through bolts; themovable air cylinder is embedded into the middle position of in the top plate and is connected to the mounting seat through a bolt; and the air cylinder rod is inserted at the lower end of the movable air cylinder. The tensile strength detection device has the beneficial effects that by arranging the fixed plate rack adjusting and clamping structure, the position of the connecting plate rack in amovable groove can be more reasonably adjusted, so that the fixed plate rack adjusting and clamping structure can fix protecting films of different sizes conveniently.

Description

technical field [0001] The invention belongs to the technical field of protective film detection devices, in particular to a protective film tensile strength detection device. Background technique [0002] Protective film can be divided into digital product protective film, car protective film, household protective film, food fresh-keeping protective film, etc. according to the purpose. The tensile strength test of the protective film is an indispensable link for the factory inspection of the protective film. The existing technology is a Chinese patent. The technical solution adopted by the protective film tensile strength detection device with the publication number CN201710257810.9 is: including a processor, two parallel and opposite equal-length brackets, a tension meter, a servo motor and a winch connected to the servo motor. The tension gauge and the servo motor are connected to the processor, and two opposite clamping devices are arranged vertically between the two bra...
