An inner bag grabbing mechanism for double-layer ton bags

Abstract

The invention discloses an inner bag grabbing mechanism for a double-layer ton bag, which comprises: a frame, an air supply pipe, an axial flow fan, a horizontal moving component, an inflatable pipe, bumps, and a clamping cylinder, and the air supply pipe is fixedly connected to the base On the bracket, an axial flow fan is installed at one end of the air supply pipe, and a sleeve is installed at the other end. The horizontal moving assembly comprises a block driving motor, a guide rail, a rack and a base, a gear is installed on the output shaft of the translation driving motor, and a rack is installed between two symmetrical guide rails. A plurality of clamping blades are hinged on the inflatable tube, and the section of the clamping blades is arc-shaped, and a reset spring is installed at the root of the clamping blades, and the convex point is made of soft material, and is installed on the inner side of the clamping blades. The expansion rod of the clamping cylinder is fixedly connected with the connecting rod, and the clamping cylinder drives the inflation tube to move in the sleeve, and the sleeve can push the clamping cylinder and the side wall of the inflation tube to be clamped. The invention is automatic, improves the working efficiency of grasping and inflation, and the clamping blades are provided with convex points to prevent the inner bag from loosening.

Description

technical field [0001] The invention belongs to the field of automatic production line of large-sized bags, and in particular relates to an inner bag grasping mechanism of double-layered large-sized bags. Background technique [0002] Big bag is a kind of flexible transport packaging container. The big bag has the advantages of moisture-proof, dust-proof, radiation-resistant, firm and safe, and has sufficient strength in structure. Due to the convenience of loading and unloading and handling of container bags, the loading and unloading efficiency has been significantly improved, and it has developed rapidly in recent years. For powdery items that are prone to spillage, the packaging requirements are high. The double-layer big bag is used to pack this kind of powder products, and the bag body is composed of at least two layers of outer and inner layers. The outer bag is made of compound film and plastic woven, and the inner bag is made of polyethylene film. This container...
