A woven bag grabbing device

Abstract

The invention discloses a woven bag gripping device. The woven bag gripping device comprises a supporting plate, first air cylinders are arranged at the four corners on the top of the supporting plate, piston rods at the ends of the first air cylinders are fixedly connected with the supporting plate, vertical sliding grooves are formed in the two ends of the supporting plate respectively, transverse sliding grooves are vertically formed in the inner sides of the two vertical sliding grooves respectively, and the vertical sliding grooves are communicated with the transverse sliding grooves. A through hole runs through the center of the supporting plate, a positive and reverse motor is arranged on the top of the supporting plate, the output shaft of the positive and reverse motor penetratesthrough the through hole, the end of the positive and reverse motor is connected with a second air cylinder, and the bottom of a piston rod at the end of the second air cylinder is provided with a disc. The four corners of a to-be-gripped woven bag are compressed by using a frame plate, the to-be-gripped woven bag is helped to be fixed by using second insertion needles, then the disc is driven through the positive and reverse motor to rotate forwards, so that first insertion needles on the bottom of the disc are inserted into gaps on the woven bag, the woven bag can be easily gripped, and thegripping efficiency is high.

Description

technical field [0001] The invention relates to the field of grasping equipment in the packaging industry, in particular to a woven bag grasping device. Background technique [0002] Plastic woven bags are made of polypropylene as the main raw material, which are extruded and stretched into flat filaments, and then woven and woven into bags. They are usually used for packaging powdery or granular solid materials and flexible items. In the existing process of grabbing a packaging bag, a suction cup is usually used to suck up the bag, but since the plastic woven bag is woven with flat wire, and the plastic woven bag has air permeability, when grabbing the packaging bag, It is easy to cause capture failure. [0003] Therefore, it is necessary to invent a woven bag grabbing device to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to provide a grabbing device for woven bags, which uses a frame plate to compress the four co...
