When the woven bag production line is practically applied, firstly, plastic particle raw materials are placed in an extruder to be heated, melted and extruded, the extruded plastic particles enter a film drawing die after being extruded, the plastic is changed into a film through the film drawing die, the film is cooled and formed through a cooling device, then the film continuously moves, is spread under the action of an arc-shaped guide plate and is wound on a first guide roller, the operation can ensure that the film is spread on the first guide roller flatly, the subsequent cutting quality is ensured, the quality of flat yarns is ensured, the film continuously advances, is cut into a plurality of flat yarns through a film cutting device, the flat yarns continuously run, enter a flat yarn collecting device to be collected, the collected flat yarns are applied to a circular weaving device, the circular weaving device weaves continuous cylindrical woven bags by using the flat yarns, and the woven bags are printed through a roll printing device, specifically: the triangular support roller group is integrally arranged inside the woven bag, the supporting roller supports the triangular support roller group in a rolling mode through the woven bag, then the open end of the woven bag is arranged on the driving roller group and used for driving the woven bag to move forwards, after adjustment is completed, the printing assembly moves downwards and presses the surface of the roller at the top of the triangular support roller group through the woven bag, the driving roller group pulls the woven bag to move forwards, the woven bag moves relative to the triangular support roller group, each roller of the triangular support roller group and the supporting roller roll, meanwhile, the printing assembly prints patterns and characters on the surface of the woven bag, compared with traditional printing, the device can separate two layers of woven bags, only prints the patterns on the surface of a specific woven bag, prevents printing ink from permeating to other positions, is good in printing quality, and the woven bag after printing is under the action of the first driving roller, the woven bags are conveyed to the first stop lever, the first swing frame freely swings downwards under the action of gravity, then under the action of the second driving roller, the woven bags from the first stop lever are conveyed to the length of a single woven bag, the bag roll has large weight and rotates slowly, so that the length of one woven bag is not suitable for feeding at one time, when the woven bags are actually used, the first driving roller continuously feeds the woven bags, the second driving roller feeds the woven bags rapidly and intermittently, the swinging of the first swing frame can coordinate the feeding processes of the first swing frame and the second swing frame to ensure normal feeding, then, under the action of the lifting frame

Optimized, the second transport mechanism rotates the installation drive wheel including articulated third rocker that sets up in the frame on the third rocker, the third rocker is driven by the third rocker actuating mechanism that sets up in the frame, and the periodic swing of third rocker, when the drive wheel swung the braided bag surface to first transport mechanism on, the drive wheel carried the braided bag to setting up on the second conveyer belt in drive wheel rear. The third swing frame driving mechanism drives the third swing frame to intermittently swing, the driving wheel continuously operates, and when the driving wheel swings to the surface of the woven bag on the first transfer mechanism, the woven bag is conveyed to the second conveying belt arranged behind the driving wheel by the driving wheel, so that the conveying direction of the woven bag is changed, and the subsequent sewing is normally performed.

Optimized, use the moving direction of braided bag on second transport mechanism as the back, the turn-ups piece is located one side of second transport mechanism, and backward in the past, turn-ups piece curls to the inboard gradually, is horizontal U-shaped to the cross sectional shape of turn-ups piece until curling, still including rotating the compression roller of installing in the frame, compression roller axis perpendicular to braided bag direction of motion, compression roller press the braided bag surface on second transport mechanism, and the braided bag removes, and the one end of braided bag curls gradually under the effect of turn-ups piece, until folding together, gets into the sewing machine and sews up the position. The compression roller is pressed the braided bag on second transport mechanism, and second transport mechanism moves, drives the braided bag motion, and the braided bag removes, and the one end of braided bag curls gradually under the turn-ups piece effect, until together, gets into the sewing machine and sews up the position and make up can, make up the process and need not artifical the participation, and with process seamless connection around, production efficiency is higher.

Optimized, turn over the bag goods of furniture for display rather than for use and include two piece at least arc driving lever, the pivot that is parallel to each other, the one end setting of arc driving lever is in the pivot, and the pivot is rotated and is installed in the frame, turns over the bag goods of furniture for display rather than for use actuating mechanism drive by the bag goods of furniture for display rather than for use that turns over that sets up in the frame and reciprocates, and the braided bag that falls from the second transport mechanism end is located arc center one side of arc driving lever, and arc center one side of arc driving lever still is provided with the third conveyer belt, and the arc. The braided bag is followed the end of second transport mechanism and is fallen down, the braided bag is vertical or tilt state basically, turn over bag goods of furniture for display rather than for use actuating mechanism work afterwards, the drive turns over the bag goods of furniture for display rather than for use and swings to braided bag place direction, the arc driving lever is then beaten on the braided bag, because can receive the wind resistance influence during the braided bag motion, the arc driving lever then can prevent the skew predetermined movement track of braided bag, ensure that the braided bag is stirred to preset position, the arc driving lever stirs the braided bag to the third conveyer belt on, the third conveyer belt is sustainable carries the braided bag to next station, also can accumulate the braided bag to once only transport away after certain quantity, so that carry out the processing of next process.

Preferably, the position of the pressing mechanism pressed on the woven bag is located right above the woven bag supporting piece. The position of pressing the pressing mechanism on the woven bag is arranged right above the woven bag supporting piece, so that when the pressing mechanism is pressed downwards, the pressing mechanism cannot collapse the woven bag, and the lower clamping jaw is normally pulled out and the subsequent woven bag is normally fluffy.

Preferably, the woven bag is provided with packing belt fixing parts on two sides of the moving track above the woven bag supporting part, the annular packing belt is detachably fixed on the packing belt fixing parts, the annular packing belt is supported after the woven bag is fluffy, and the annular packing belt is separated from the packing belt fixing parts. The packing area mounting can fix annular packing area according to specific gesture, then can strut annular packing area after the braided bag is fluffy to shake off it from the packing area mounting, in order to realize automatic packing, practice thrift manpower resources and comparatively safe.

The invention has the advantages that:
