New four shuttle circular loom

The utility model relates to a plastic woven bag production equipment, in particular to a new four-shuttle circular loom. The feature is that the cam (4) and the shuttle (22) are improved on the basis of the original four-shuttle circular loom structure. The lift and the descending part of the track curve on the cam (4) are sinusoidal, and the climbing angle α is 5 ° -15°, the wave-valley and wave-valley and peaks and crests of a lift-descent cycle period and the other week are all arc-connected; the head of the shuttle (22) is a streamlined structure, and the length of the shuttle (22) is 450-500mm. The width is 90-100mm. After the improvement of the whole machine, the operation is stable and the noise is low. The reduction of energy consumption is reduced from 4KW to 3KW, prolonging the service life of the relevant wearing parts, and also reducing the number and cost of user maintenance, improving the production environment and increasing the output.
