Bag bottom folding preventing device for double-layer bag bagging machine

Abstract

The invention discloses a bag bottom folding preventing device for a double-layer bag bagging machine and belongs to the field of package bag processing equipment. The bag bottom folding preventing device for the double-layer bag bagging machine comprises a bag grabbing rack mounted on the driving guide sliding mechanism of the bagging machine, a left retracting mechanism and a right retracting mechanism mounted on the left and the right of the bag grabbing rack respectively, a left mechanical claw and a right mechanical claw, wherein the left mechanical claw is connected with the left retracting mechanism through a left bag grabbing arm, the right mechanical claw is connected with the right retracting mechanism through a right bag grabbing arm, the bag grabbing rack is used for driving the left mechanical claw and the right mechanical claw to move back and forth, the left retracting mechanism and the right retracting mechanism are used for driving the left mechanical claw and the right mechanical claw to move towards the inside or the outside of the bag grabbing rack, and the left mechanical claw and the right mechanical claw are used for clamping internal bags. The bag bottom folding preventing device for the double-layer bag bagging machine solves the problem of folding of the inner bags of double-layer bags and can fully fill the bottoms of the bags with materials during application, thereby making full use of space of the double-layer bags. Meanwhile, the bag bottom folding preventing device for the double-layer bag bagging machine is simple in structure and good in use effects.

Description

technical field [0001] The invention relates to a double-layer bag-covering machine, more specifically, to a bag-bottom chamfer-proof device for the double-layer bag-covering machine. Background technique [0002] Chinese Patent No. ZL201220268047.2, the authorized announcement date is December 26, 2012, and the name of the invention is: double-layer bag bagging machine. This application is a product independently researched and designed by the applicant in the early stage. Machine automation replaces the original manual work, saving manpower. The application includes a frame and an outer bag device installed on the frame, a sorting device, a bag feeding device, a bag opening device, an inner bag feeding device and an inner bag pulling device. The double-layer bag bagging machine of this application can complete the automatic conveying of the inner and outer bags and the automatic bagging function, thereby realizing the high-speed and high-quality processing of the double-l...
