[0037] As shown in the figure, the woven bag is described in detail:

[0038] A woven bag comprises a cylindrical bag body 101, and a sewing strip 102 formed by sewing one of the ends of the bag body 101, auxiliary belts 103 are sewn on both sides of the sewing strip 102, and two carrying parts 104 are provided on the two auxiliary belts 103. The carrying parts 104 are not sewn with the sewing strip 102 and are used for carrying the bag body 101 at one end to quickly discharge the contents of the bag body 101.

[0039] The bag body 101 is used to hold substances. The sewing strip 102 at one end is supplemented and fixed by two auxiliary belts 103, thereby increasing the firmness of the sewing of the end. At the same time, by setting the lifting part 104, when the substance in the bag body 101 is discharged, the end without the auxiliary belt 103 is opened, and then the bag body 101 is pulled up by the lifting part 104, so that the bag body 101 is in an upright state, thereby quickly discharging the substance in the bag body 101, thereby improving the efficiency of discharging the substance from the woven bag.

[0040] Further:

[0041] The carrying parts 104 of the two auxiliary belts 103 are symmetrically arranged, so that when carrying, the corresponding carrying parts 104 on the two auxiliary belts 103 can be taken at the same time, ensuring the load-bearing capacity of the carrying parts 104 while ensuring that the woven bag is balanced in force, and then in a vertical state to quickly discharge the material.

[0042] As shown in the figure, the woven bag processing device is described in detail:

[0043] A woven bag processing device is used for processing an auxiliary belt 103, comprising a platform frame 201, a door-shaped plate Ⅰ202 is fixed to the front of the platform frame 201, a sliding limit frame 301 passes through the door-shaped plate Ⅰ202, a T-shaped frame 302 is fixed to the lower end of the limit frame 301, a middle plate 304 arranged in the front-to-back direction is fixed to the lower end of the T-shaped frame 302, left and right parts of the platform frame 201 are provided with track grooves 203, the two track grooves 203 are staggered, and folding mechanisms are installed in the two track grooves 203, and a sewing device 204 is provided at the rear of the platform frame 201 for sewing and fixing the belt strips folded into three layers.

[0044] When in use, the single-layer strip of raw material is placed between the middle plate 304 and the platform frame 201, and the middle part of the single-layer strip is aligned with the middle plate 304; then the single-layer strip is moved backward, and during the movement, it will pass through two folding mechanisms in sequence, so that parts of the two sides of the single-layer strip are folded onto the middle plate 304, so that the single-layer strip of raw material forms a three-layer strip; as the strip moves, the three-layer strip will separate from the middle plate 304 and pass through the sewing device 204, so as to be sewn and fixed, thereby continuously supplying the single-layer strip of raw material, forming continuous processing of the auxiliary belt 103, and the processing efficiency is high.

[0045] Among them, a spring III 303 is provided between the limit frame 301 and the door-shaped plate I 202, so that the middle plate 304 presses the platform frame 201 downward, so that the device can adapt to single-layer strips of raw materials of different thicknesses, and at the same time can make the single-layer strip fit on the platform frame 201 in a single-layer state.

[0046] As shown in the figure:

[0047] A U-shaped frame 305 is fixed on the T-shaped frame 302, and a bidirectional screw 403 is rotated through the U-shaped frame 305. Two L-shaped plates 401 are symmetrically threaded on the bidirectional screw 403. Extension plates 402 are fixed to the rear ends of the two L-shaped plates 401. The front ends of the two extension plates 402 are attached to the rear ends of the middle plate 304 to form an extension.

[0048] By rotating the bidirectional screw 403, the two L-shaped plates 401 can be threadedly driven to move closer or farther away at the same time, thereby driving the two extension plates 402 to move closer or farther away. When the two extension plates 402 are in contact, the two extension plates 402 form a whole, and the width is the same as the width of the middle plate 304. When the two extension plates 402 are separated, the overall width of the two extension plates 402 increases, and the pressing effect of the middle plate 304 on the single-layer strip is maintained, thereby increasing the middle width of the single-layer strip, thereby increasing the width of the three-layer strip after folding, thereby ensuring that the device can adapt to the processing of auxiliary belts 103 of different widths.

[0049] As shown in the figure:

[0050] The folding mechanism includes a slide 501 sliding in the track groove 203, a protrusion 503 is provided at the upper end of the slide 501, a slope block 502 extends from the front end of the protrusion 503, a folding plate 505 extends from the upper end of the protrusion 503 toward the middle of the platform frame 201, a pillar 506 is fixed to the slide 501 away from the folding plate 505, a support plate 507 is fixed to the end of the pillar 506 away from the slide 501, and a spring I 508 is provided between the support plate 507 and the slide 501 to make the protrusion 503 press against the extension plate 402.

[0051] When the single-layer strip laid flat on the platform frame 201 moves to the slide 501, it first contacts the slope block 502, thereby guiding the slope block 502, and the single-layer strip is tilted upward at the part not pressed by the extension plate 402 until it moves to the protrusion 503 and then tilts to the highest point, and then contacts the folding plate 505. Since it protrudes from the extension plate 402 in the middle, the tilted part of the single-layer strip is flipped again to the top of the extension plate 402, thereby forming a fold on one side of the single-layer strip. When the single-layer strip moves to another folding mechanism, the other side of the single-layer strip will also be folded and folded to the top of the other side, thereby obtaining a three-layer strip.

[0052] Among them, the protrusion 503 is pressed against the extension plate 402 by the elastic force of the spring I508, so that when the raised strip contacts the folding plate 505 through the protrusion 503, it is ensured that the flipped strip is folded from the root pressed by the extension plate 402, thereby ensuring the folding effect. At the same time, an angle 504 is provided near the middle end of the platform frame 201 at the connection between the protrusion 503 and the slope block 502, and the front end edge of the folding plate 505 is colinear with the angle 504, and the lower end of the front end edge of the folding plate 505 is provided with a chamfer, which can make the folding of the strip smoother and avoid the strip from being hooked with the folding mechanism, affecting the folding operation.

[0053] Further:

[0054] The support plate 507 is threadedly connected with an adjusting screw 601 , a mounting frame 602 is rotatable on the adjusting screw 601 , a pressing plate 603 slides inside the mounting frame 602 , and a spring II 604 is provided between the mounting frame 602 and the pressing plate 603 to press the lower end surface of the pressing plate 603 against the extension plate 402 .

[0055] The strip folded by the folding plate 505 may automatically tilt elastically, so a pressing plate 603 is set, and the folded strip is pressed against the extension plate 402 behind the folding plate 505, so as to ensure the folded state of the strip. At the same time, through the setting of spring II 604, it can adapt to strips of different thicknesses. At the same time, it is explained that the strip moves when there is a sufficiently large gap between the folding plate 505 and the extension plate 402, and the main pressing function is on the pressing plate 603. At the same time, the pressing plate 603 is close to the middle end of the platform frame 201 and has a section of extension backwards, which is not drawn in the figure, and is used to ensure the pressing of the strip;

[0056] The lateral position of the pressing plate 603 can be adjusted by rotating the adjusting screw 601 to correspond to different positions of the extending plate 402 .

[0057] As shown in the figure:

[0058] Two rollers 205 are provided on the platform frame 201 at the rear end of the suturing device 204 to rotate in opposite directions, and are used to transport the suturing and fixed auxiliary belt 103 backwards.

[0059] The outer surface of the roller 205 is provided with a rubber layer.

[0060] By driving the two rollers 205 to rotate in opposite directions, the auxiliary belt 103 located between the two rollers 205 is transported backward, thereby forming a continuous movement of the single-layer strip of raw material, thereby ensuring continuous processing of the auxiliary belt 103.

[0061] By setting the rubber layer, it can be deformed and then adapt to the transportation of auxiliary belts 103 with different thicknesses.

[0062] As shown in the figure:

[0063] A door-shaped plate II 206 is fixed to the rear end of the platform frame 201 , a knife holder 701 is slidably passed through the door-shaped plate II 206 , and a cutter 702 is provided at the lower end of the knife holder 701 .

[0064] By controlling the knife holder 701 to move downward through the electric telescopic rod, the cutter 702 can cooperate with the rear edge of the platform frame 201 to cut the auxiliary belt 103 to obtain the auxiliary belt 103 of a suitable length.

[0065] Further:

[0066] A processing method using the woven bag processing device includes:

[0067] S1, placing a single-layer strip of raw material between the middle plate 304 and the platform frame 201, and aligning the middle of the single-layer strip with the middle plate 304;

[0068] S2, moving the single-layer strip backward, and then passing through two folding mechanisms in sequence, so that parts of both sides of the single-layer strip are folded onto the middle plate 304 to form a three-layer strip;

[0069] S3. The three-layer belt strips are passed through the sewing device 204 and sewn and fixed to obtain the auxiliary belt 103.
