Rolling type shuttle wheel-free double xiaoliu shuttle plastic circular loom

Abstract

The invention relates to a manufacturing device of polypropylene (PP) knitted bags, in particular to a tumbling-type double-six-small-shuttle plastic round loom without shuttle wheels. The main technical characteristics of the invention are that six shuttles without shuttle wheels are arranged at the upper and lower levels respectively between the upper door ring and the lower door ring on the basis of the prior sliding-rail plastic round loom without shuttle wheels. Meanwhile, 30-72 pillars are respectively distributed between the upper and lower door rings. Rails for movement are arranged in two layers for the upper shuttle and the lower shuttle. The PP knitted bags made by the upper shuttle are coiled up by the first coiling machine through the upper size ring, upper width widening machine and upper traction and likewise the bags made by the lower shuttle are coiled up by the second coiling machine through the lower size ring, lower width widening machine and lower traction. A plastic round loom can produce two bags simultaneously, the efficiency of which triples the traditional four-shuttle round loom and doubles the small six-shuttle round loom.

Description

technical field [0001] The invention relates to plastic woven bag production equipment, in particular to a rolling shuttleless double-small six-shuttle circular loom. technical background [0002] At present, the plastic circular looms used in the production of plastic woven bags in various countries in the world are divided according to the number of shuttles: four-shuttle circular looms, six-shuttle circular looms, small six-shuttle circular looms, large eight-shuttle circular looms, and large twelve-shuttle circular looms. Shuttle circular looms are divided according to the host structure: brown belt type plastic circular loom, palm rod type plastic circular loom, small cam plastic circular loom, plane small cam plastic circular loom. In order to improve weaving efficiency, many domestic and foreign Plastic machine experts have spent a lot of energy trying to improve the circular loom's speed by reforming the relevant structure, but with little success.
