Description

Packaging bag falling testing device Technical Field The invention relates to the technical field of packaging bag quality detection devices, in particular to a packaging bag breaking testing device. Background The woven bag is used as a common industrial and agricultural product packaging carrier, and needs to bear drop impact in the actual storage and transportation process, so that drop performance inspection is an important detection item for evaluating whether the quality of the woven bag is qualified or not. The traditional testing method mainly depends on manual operation, operators need to repeatedly carry and throw heavy packaging bags to a designated height, so that the method not only consumes a large amount of human resources and has low testing efficiency, but also is difficult to accurately control the falling height, the initial posture of the packaging bags and the instantaneous stress state of release, so that the testing result is easily interfered by artificial factors, the repeatability and the scientificity are insufficient, and a scientific and reliable evaluation basis cannot be provided for the product quality. Some existing testing methods also adopt a falling bag testing device, such as a plastic woven bag falling test device provided by the Chinese patent with publication number of CN109142099A, which alternately lifts and releases the packaging bag through two lifts, so that the manual labor intensity is reduced to a certain extent, the testing efficiency is improved, the releasing mode of the device depends on the falling of the packaging bag on an inclined push plate, the falling gesture and the landing direction are single and are difficult to accurately control, and the falling condition in actual transportation cannot be simulated, and the falling bag testing device also comprises a novel heavy packaging bag falling bag testing machine provided by the Chinese patent with publication number of CN121068383A, which can realize flexible switching between horizontal falling test and vertical falling test through an adjustable vertical assembly, can be suitable for packaging bags with different sizes, but can still interfere or rub with the packaging bag at the releasing moment through a guide roller and a bottom supporting structure used for clamping and fixing the packaging bag, so that unexpected deviation or rotation can occur when the packaging bag falls, and the falling state and the falling angle testing accuracy is influenced. Disclosure of Invention Aiming at the defects in the prior art, the invention provides a packaging bag falling testing device, which solves the problems that the falling posture and the landing direction of a packaging bag in the prior device are single, are difficult to control accurately, are easy to interfere or rub with a fixed or supporting structure, cause deviation or rotation during falling, and influence the testing accuracy. According to an embodiment of the invention, a packaging bag falling testing device comprises a rack and further comprises: The lifting mechanism comprises a lifting frame which is arranged on the frame in a sliding way, and a first driving source which can drive the lifting frame to slide is fixed on one side of the frame; The clamping mechanism comprises a pair of clamping arms which are arranged at the bottom of the lifting frame in a relative rotation manner, clamping plates are arranged on the opposite sides of the two clamping arms, a first clamping part and a second clamping part are fixedly arranged on the clamping sides of the clamping plates, the clamping surface of the first clamping part is a plane and is arranged at the top or the bottom of the clamping side, and the clamping surface of the second clamping part is a horizontal concave cambered surface and is arranged in the middle of the clamping side; the second driving source is fixedly arranged on the lifting frame and can drive the two clamping arms to rotate relatively. The vertical type packaging bag vertical fixing device comprises a lifting frame, a first driving source, a second driving source, a lifting frame, a first clamping portion and a second clamping portion, wherein the lifting frame is driven to slide on the frame, a bag clamping mechanism is lowered to the ground height by the first driving source, then the two clamping arms are driven to rotate relatively, the two clamping arms are driven to approach each other by the second driving source, a packaging bag placed on the ground is clamped by the first clamping portion or the second clamping portion according to the falling posture required by a test, when a vertical falling test is required, the upper side and the lower side of the packaging bag are clamped by the first clamping portion on the two clamping plates, stable vertical fixing is achieved, when a horizontal falling test is required, the left side and the right side of the packaging bag are wrapped and clamped by the second clamp
