[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging. Their raw materials are generally polyethylene, polypropylene and other chemical plastic raw materials. Plastic woven bags are mainly composed of polypropylene bags and polyethylene bags; they are divided into bottom-sewn bags and side-sewn bottom-sewn bags according to the sewing method. They are currently widely used as a packaging material for fertilizers, chemical products and other items. Their main production process is to use plastic raw materials to extrude films, cut, and unidirectionally stretch them into flat wires, and then weave them through warp and weft to obtain products, which are generally called woven bags.

One end of the rotating sleeve 7 and the second rotating rod 8 are respectively fixedly connected to the first crushing blade 71 and the second crushing blade 81. The rotating sleeve 7 is a sleeve with openings at both ends. The second rotating rod 8 rotates inside the rotating sleeve 7 and is coaxially arranged.

[0026] Please refer again Figure 1 , Figure 2 , Figure 3 and Figure 6The screening mechanism includes a screen 6 sliding inside the mixing box 1, the inner side wall of the mixing box 1 is fixedly connected with a fixing seat, the bottom of the screen 6 and the fixing seat are connected by a tension spring 62, the center of the screen 6 is fixedly connected with a connecting sleeve 61, the connecting sleeve 61 is sleeved on the rotating sleeve 7, and the screen 6 is vibrated under the action of the connecting sleeve 61 without affecting the normal rotation of the rotating sleeve 7, and a vibration mechanism for driving the screen 6 to vibrate up and down is provided inside the mixing box 1, and the vibration mechanism includes a spring fixed at the bottom of the screen 6 The hemispherical block 63 at the bottom is fixedly connected to the rotating sleeve 7 with a billiard rod 72. When the rotating sleeve 7 rotates, the billiard rod 72 is driven to rotate, and the screen 6 is pushed up when the billiard rod 72 slides over the bottom of the hemispherical block 63. The screen 6 is then pulled down and reset by the rebound of the tension spring 62. The reciprocating vibration of the screen 6 prevents the material from blocking the screen 6 and throwing the material on the screen 6 back to the crushing mechanism for crushing. A material taking plate is detachably connected to the mixing box 1 by bolts to facilitate the cleaning of the material on the screen 6.

[0027] Please refer again Figure 1 and Figure 2 The mixing mechanism includes stirring blades 10 fixed on the second rotating rod 8. The number of stirring blades 10 is multiple groups, and the multiple groups of stirring blades 10 are distributed on the second rotating rod 8 in a linear array. When the second rotating rod 8 rotates, the stirring blades 10 are used to mix and stir the materials falling into the bottom wall of the mixing box 1 again. The bottom of the mixing box 1 is fixedly connected to a discharge pipe 11, and a detachable cover is installed at the bottom of the discharge pipe 11. After mixing is completed, the raw materials are discharged by opening the cover at the bottom of the discharge pipe 11.

[0028] Working principle: install the device at a suitable location and connect it to the municipal power supply, and connect the hydraulic rod 53 to the hydraulic system, pour a variety of raw materials into the two storage barrels 2 respectively, and start the hydraulic rod 53 to push the sliding frame 5 to slide horizontally back and forth inside the mixing box 1, drive the connecting frame 51 and the driving rack 52 to move horizontally back and forth, and drive the first rotating rod 31 to rotate under the meshing action of the driving rack 52 and the second gear 33, and drive the sliding plug plate 3 to slide reciprocatingly horizontally under the meshing action of the first gear 32 and the teeth of the sliding plug plate 3, and indirectly open the discharge port of the storage barrel 2 through the sliding plug plate 3, so that the material inside the storage barrel 2 indirectly falls into the drainage hood 4 inside the mixing box 1.

[0029] The materials are discharged to the top of the crushing mechanism by connecting the hose 41 and the sliding frame 5, and the materials are evenly discharged to the top of the crushing mechanism by the horizontal reciprocating movement of the sliding frame 5.

[0031] After crushing, the raw materials fall on the screen 6 for screening, and the qualified raw materials fall into the inner bottom wall of the mixing box 1. During the rotation of the rotating sleeve 7, the cue stick 72 passes through the hemispherical block 63 to push the screen 6 up, and then the screen 6 is pulled down by the rebound of the tension spring 62. The up and down reciprocating vibration of the screen 6 prevents the raw materials from blocking the screen 6 and affecting the screening effect of the screen 6. The up and down vibration of the screen 6 throws the raw materials on the screen 6 to the crushing mechanism for re-crushing.
