Four-connecting-rod oscillating type bag clamping device

Abstract

A four-connecting-rod oscillating type bag clamping device comprises a bag clamping device body (1), bag compressing mechanisms (2), flap mechanisms (3), bag grabbing and shrinking mechanisms (4), an oscillating mechanism (5), a frame (6) and a lifting mechanism (7). An upper blanking barrel is arranged at the upper end of the bag clamping device body (1), an inner blanking barrel is arranged on the frame (6) and inside the outer blanking barrel, the bag grabbing and shrinking mechanisms (4) are respectively hinged to the left side and the right side of the bag clamping device body (1), the flap mechanisms (3) are respectively hinged in front of and in back of the lower end of the bag clamping device body (1), the bag compressing mechanisms (2) are respectively hinged on outer sides of the flap mechanisms (3), the left side and the right side of the upper portion of the bag clamping device body (1) are hinged with the lifting mechanism (7), and the left side and the right side of the middle and lower portion of the bag clamping device body (1) are hinged with the oscillating mechanism (5). The four-connecting-rod oscillating type bag clamping device can oscillate up and down stably and highly reliably without impaction, so that a packer can realize an extremely strong packing performance.

Description

technical field [0001] The invention discloses a four-link swing type bag clamping device used for a bag opening packaging machine, which belongs to the field of packaging machinery. Background technique [0002] Patent document 200910211766.3 discloses a bag clamping device for an integral lifting packaging machine, which can increase the packaging speed of the existing packaging machine, but the disadvantage of this integral lifting bag clamping device is that the lifting parts have a large inertia, and the start and stop are not stable , In addition, its lifting mechanism adopts four linear guide rails, which requires high processing and manufacturing precision, and the linear guide rails are prone to failure in dusty environments, so the reliability of lifting is not high. Patent document 201210138772.2 discloses a gripper lifting type bag clamping device, which greatly reduces the weight of the lifting parts, and at the same time the sealing performance of the entire ba...
