The output end of motor one 606 is fixedly connected with gear column 605, which penetrates the surface of workbench 1 and is rotatably connected with the inner wall of cavity 604. Gear column 605 is meshingly connected with rack plate one 607 and rack plate two 608 on its surface. Rack plate one 607 and rack plate two 608 are respectively slidably connected with the surface of one group of placing grooves 603.

[0026] The above components achieve the following effects: starting motor one 606 makes gear column 605 rotate, which in turn makes rack plate one 607 and rack plate two 608 move towards each other or move away from each other. When rack plate one 607 slides into cavity 604 along placing groove 603, rack plate two 608 slides into dust collection groove 602 along placing groove 603. When rack plate two 608 slides into cavity 604, rack plate one 607 slides into dust collection groove 602. Rack plate one 607 and rack plate two 608 alternately open and close, so that dust collection box 601 does not always remain in an open or closed state without affecting the dust collection effect. This avoids dust always being exposed and easily being lifted to cause secondary pollution to the woven bag.

[0027] Specifically, the side surface of dust collection groove 602 close to placing groove 603 is fixedly connected with cleaning brushes 609, and the number of cleaning brushes 609 is two groups and symmetrically arranged.

[0030] The effect achieved by the above-mentioned components is that: before the woven bag is conveyed from a group of conveying rollers 3 to the pressing roller 4 and preliminarily pressed with the film, the two groups of cleaning rollers 614 clean the dust on the surfaces of the two sides of the polypropylene woven bag, and the cleaning roller 614 slides up and down in the sliding groove 611 together with the sliding block 613 under the action of the spring one 612, which does not affect normal conveying and can adapt to woven bags of different thicknesses.

[0031] Specifically, the number of the fixed frame 610, the sliding groove 611, the spring one 612, the sliding block 613 and the cleaning roller 614 is two groups and symmetrically arranged, and the number of each group of the sliding groove 611, the spring one 612 and the sliding block 613 is two and symmetrically arranged.

[0032] The effect achieved by the above-mentioned components is that: two groups of cleaning rollers 614 are arranged to clean the dust on the surfaces of the two sides of the woven bag.

[0033] Specifically, the surface of the workbench 1 is provided with the anti-wrinkle device 7, the anti-wrinkle device 7 includes a protective cover 701, the surface of the protective cover 701 is fixedly connected with the workbench 1, the surface of the protective cover 701 is fixedly provided with a motor two 702, the output end of the motor two 702 is fixedly connected with a bidirectional threaded rod 703, the bidirectional threaded rod 703 is rotatably connected with the inner wall of the protective cover 701, and the surface of the bidirectional threaded rod 703 is threadedly connected with a movable block one 704.

[0034] The effect achieved by the above-mentioned components is that: starting the motor two 702 makes the bidirectional threaded rod 703 rotate, and then makes the two groups of movable block one 704 move towards each other or move away from each other, and the protective cover 701 is arranged to facilitate formal pressing and avoid the cleaned woven bag from being polluted by dust again.

[0035] Specifically, the inner wall of the protective cover 701 is fixedly connected with a guide column 705, the surface of the guide column 705 is slidably connected with a movable block two 706, the surfaces of the movable block one 704 and the movable block two 706 are fixedly connected with a fixed rod 707, the surface of the fixed rod 707 is provided with a T-shaped groove 708, the surface of the T-shaped groove 708 is fixedly connected with a spring two 709, the other end of the spring two 709 is fixedly connected with a T-shaped rod 710, the T-shaped rod 710 is slidably connected with the surface of the T-shaped groove 708, and the other end of the T-shaped rod 710 is rotatably connected with a compression roller 711.

[0036] The above-mentioned components achieve the effects that the starting motor two 702 makes the movable block one 704 repeatedly move towards and away from each other on the bidirectional threaded rod 703, drives the compression roller 711 to repeatedly roll and compress on the surface of the woven bag and the film, avoids bubbles or wrinkles between the two, and makes the two groups of compression rollers 711 move away from each other after compression, so that the woven bag and the film are taut, facilitating compression, the movable block two 706 and the guide column 705 are arranged to assist the movement of the compression roller 711 and avoid the movable block one 704 rotating with the bidirectional threaded rod 703, and the T-shaped rod 710 and the T-shaped groove 708 are arranged to avoid the T-shaped rod 710 from being separated from the fixed rod 707 without affecting sliding.

[0037] Specifically, the number of the movable block one 704, the movable block two 706, the fixed rod 707, the T-shaped groove 708, the spring two 709, the T-shaped rod 710 and the compression roller 711 is two groups and symmetrically arranged, the number of each group of the fixed rod 707, the T-shaped groove 708, the spring two 709 and the T-shaped rod 710 is two and symmetrically arranged, and the surface of the protective cover 701 is provided with a through groove 712.

[0038] The above-mentioned components achieve the effects that the multiple groups of the fixed rod 707, the T-shaped groove 708, the spring two 709 and the T-shaped rod 710 enable the compression roller 711 to be moderately adjusted in height, avoid excessive compression and tautness of the woven bag and the film, and avoid damage to the two, and the through groove 712 is arranged to facilitate the woven bag and the film to enter and exit the protective cover 701.

[0039] Working principle: through the setting dustproof device 6, when the polypropylene woven bag is conveyed from a group of conveying rollers 3 to the compression roller 4 and the film is preliminarily compressed, two groups of cleaning rollers 614 will clean the dust on the surface of the polypropylene woven bag, the cleaning roller 614 will slide up and down in the sliding groove 611 under the action of the spring 612 and the sliding block 613, which can adapt to different thickness of the woven bag without affecting the normal conveying. The initial state is that the rack plate one 607 is located in the dust collection tank 602 and the rack plate two 608 is located in the cavity 604. The dust cleaned falls into the dust collection tank 602 and the surface of the rack plate one 607. Starting the motor one 606 makes the gear column 605 rotate, and then the rack plate one 607 and the rack plate two 608 move towards each other, so that the rack plate one 607 slides into the cavity 604 along the placing groove 603 and the rack plate two 608 slides into the dust collection tank 602 along the placing groove 603. In this process, the cleaning brush 609 cleans the dust on the surface of the rack plate one 607 and makes it fall into the dust collection tank 602 and the surface of the rack plate two 608. Then reverse the motor one 606 to make the rack plate two 608 slide into the cavity 604 and the rack plate one 607 slide into the dust collection tank 602. In this process, the cleaning brush 609 cleans the dust on the surface of the rack plate two 608 and makes it fall into the dust collection tank 602. Avoiding the dust cleaned always being exposed, it is easy to be raised and cause secondary pollution to the woven bag. Through the setting dustproof device 6, the dust cleaned is properly collected and will not be raised again to cause secondary pollution to the woven bag. It effectively improves the ease of use of the equipment.
