Description

Woven bag stacking mechanism Technical Field The utility model relates to woven bag processing equipment, in particular to a woven bag stacking mechanism. Background After the production and processing of the woven bags are completed, the woven bags are packed into bundles by a packer, and then the bundles of woven bags are orderly and stably stacked by matching with the stacking operation, so that the woven bags are convenient to store, transport and process. Along with the development of technology, the stacking operation is replaced by a machine, and the existing stacking machine is used for grabbing bundles of woven bags through a stacking mechanism with a mechanical arm matched with the tail end, and accurately placing the bundles of woven bags at a designated position according to the setting, so that automatic stacking is realized. The existing stacking mechanism mainly comprises an arm support, two claw arms rotatably arranged on the arm support, a plurality of claw fingers respectively arranged on the claw arms, and a driving assembly for driving the two claw arms to act. When the production requirements of enterprises change, for example, woven bags with different specifications, materials or weights are required to be grabbed, the claw fingers are required to be replaced, so that the claw fingers can better meet diversified grabbing requirements, and the grabbing stability is ensured. However, the existing claw is fixed on the claw arm through a fastener, and needs to be operated one by one in the disassembly and assembly process, and the disassembly and assembly mode is large in manual operation amount and affects the production efficiency of the woven bag to a certain extent. Disclosure of utility model The utility model aims to provide a woven bag stacking mechanism which can realize convenient disassembly and assembly of claw fingers, so that the manual operation amount is reduced, and the production efficiency of woven bags is increased. The technical aim of the utility model is achieved through the following technical scheme that the woven bag stacking mechanism comprises an arm support, two claw arms rotatably mounted on the arm support through a rotating shaft, a plurality of claw fingers respectively mounted on the claw arms and a driving member for driving the two claw arms to act, wherein an inserting structure is arranged between each claw finger and each claw arm, the inserting structure is provided with an inserting state and a separating state, a fixing plate is detachably and fixedly mounted on each claw arm, and a limiting structure for limiting the inserting structure to be in the inserting state is formed between the fixing plate and each claw finger. Through adopting above-mentioned technical scheme, when the change to the claw finger is to be realized, dismantle the fixed plate that is fixed in on the claw arm, can release limit structure to inserting the spacing that the structure constitutes, and then can be with inserting the structure and switch to the separation state from inserting the joining in marriage the state to this realizes convenient dismouting separation of claw finger and claw arm. The fixing operation of all the claw fingers can be relieved by disassembling the fixing plate, so that the manual operation amount for disassembling and assembling the claw fingers can be greatly reduced, and the production efficiency of the woven bag can be increased.
