Full bag discharging, opening and transferring mechanism

Abstract

The invention belongs to the field of packaging machines, and relates to a full bag discharging, opening and transferring mechanism which comprises a support. An end mounting seat of the support is connected with an outer bag opening cylinder in a swinging mode through connecting rods. A swing arm is rotationally connected to a support body of the support. The end of a piston rod of the outer bag opening cylinder is connected with a swing arm connecting rod, the swing arm connecting rod is connected with a bent portion at one end of the swing arm, and the other end of the swing arm connecting rod is connected with a fixing seat. A driving cylinder is mounted on the fixing seat. An auxiliary clamping arm is fixed to a transverse mounting plate at the outer end of the fixing seat, a main clamping arm is rotationally arranged at the top end of the outer side of the fixing seat, and a connecting portion of the main clamping arm is connected with a piston rod of the driving cylinder. Through a transferring mechanism arranged above a full bag, dust can be prevented from being accumulated on a transferring transmission mechanism, and therefore reliability and high efficiency of equipment are improved; through the four-link transferring mechanism, a large full bag transferring distance can be achieved; through the outer bag opening mechanism which is obliquely downward and a horizontal tongs mechanism, the full bag discharging, opening and transferring mechanism can be suitable for a fixed type dust bag clamping mechanism.

Description

technical field [0001] The invention belongs to the field of packaging machinery, and relates to a bag-supporting bag transfer mechanism under a full bag. Background technique [0002] In the bag-opening packaging machine, the full bag filled with materials needs to be transferred from the bagging position. There are two existing transfer methods: one is the lower horizontal and longitudinal transfer method, and the transmission mechanism is arranged below the full bag. The disadvantage of this method is that materials and dust are easy to accumulate on the transmission mechanism, causing mechanical failure; the other is the upper horizontal transfer method, the transmission mechanism is arranged above the full bag, and the full bag is horizontally moved by the swing of the four-link mechanism. The disadvantage of this method is that the distance of lateral transfer is small, and it can only be applied to the duckbill or liftable bag clamping mechanism. Contents of the inv...
