Description

Technical Field

[0001] The invention relates to the technical field of non-woven bag production, in particular to an automatic deviation-correcting device for production and cutting of non-woven bags. Background Art

[0002] Non-woven bags are environmentally friendly bags made of non-woven fabrics. They are degradable, breathable, non-toxic, non-irritating, and recyclable. The production of non-woven bags requires folding, heat sealing, and slitting. Finally, the opening end of the bag is cut with a special-shaped knife to form a handle shape (such as Figure 7 ).

[0003] At present, the non-woven bag production line generally adopts the original plastic bag production line. When cutting, multiple bags need to be stacked together first, and then cut at one time with a cutter.

[0004] However, plastic bags are made of PP or PE materials, which have low surface energy and are prone to static electricity, which makes them easy to adsorb to each other. After the bags are stacked, they are not easy to shift or misalign, and the cutting accuracy is high. Non-woven bags have a rough surface, with many gaps between fibers, and the bags are highly independent. They are easy to shift during and after stacking, which increases the cutting error and affects the product quality. Summary of the invention

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-Figure 6 , a technical solution provided by the present invention:

[0042] An automatic deviation-correcting device for production and cutting of non-woven bags comprises a base 1, to which a support frame 5 is fixedly connected.

[0043] The base 1 is provided with a conversion mechanism 2, to which two deflection correction discs 3 are connected. The two deflection correction discs 3 are symmetrically distributed and used to receive the non-woven bags to be cut. The conversion mechanism 2 is used to convert the positions of the two deflection correction discs 3. The deflection correction discs 3 are connected with a correction mechanism 4.

[0044] The support frame 5 is provided with a counting mechanism 6 for counting the non-woven bags on the deflection correcting disk 3 , and the support frame 5 is provided with a cutting mechanism 7 for cutting the non-woven bags on the deflection correcting disk 3 .

[0045] The conversion mechanism 2 includes a steering motor 21, which is fixedly mounted on the support frame 5. A turntable 22 is fixedly mounted on the output end of the steering motor 21. Both the two correcting discs 3 are fixedly mounted on the turntable 22. The steering motor 21 and the turntable 22 can simultaneously drive the two correcting discs 3 to rotate synchronously.

[0046] The correction mechanism 4 includes two symmetrically arranged folding plates 41, the bottoms of the two folding plates 41 are slidably connected to the deflection correction disk 3, the two folding plates 41 are fixedly connected to the opposite sides with a slide bar 42, the slide bar 42 is slidably connected to the inner wall of the deflection correction disk 3, and a support spring is sleeved on the outside of the slide bar 42, and the two ends of the support spring are respectively connected to the folding plates 41 and the deflection correction disk 3. The top ends of the two folding plates 41 are deflected outward to form an "open" state, so that the non-woven fabric can be guided so that the non-woven fabric can enter between the two folding plates 41.

[0047] The correction mechanism 4 further includes a fixing seat 44 , which is fixedly connected to the inner wall of the deviation correction disk 3 , and a pressing component 46 and a limiting component 45 are arranged on the fixing seat 44 .

[0048] The limiting assembly 45 includes a bidirectional screw rod 451, which is rotatably connected to the inner wall of the fixed seat 44. The bidirectional screw rod 451 has two sections of threads in opposite directions, and two sleeves 452 are respectively threadedly connected to the two sections of threads. The opposite ends of the two sleeves 452 are fixedly connected to the limiting plates 453. The opposite sides of the two limiting plates 453 are respectively in contact with the two folding plates 41, which are respectively used to limit the distance between the two folding plates 41, so that the spacing between the two folding plates 41 is adapted to the width of the non-woven bag. A toggle is fixedly connected to the bidirectional screw rod 451 to control the rotation of the bidirectional screw rod 451. A guide rod 454 is slidably connected to the inner wall of the limiting plate 453, and the guide rod 454 is fixedly connected to the fixed seat 44 to limit the circular motion of the limiting plate 453 and the sleeve 452, so that when the bidirectional screw rod 451 rotates, a spiral transmission can be generated between the sleeve 452.

[0049] The pressing assembly 46 includes a support plate 461, the bottom end of which is fixedly connected to the fixed seat 44, a rotating shaft 462 is rotatably connected to the support plate 461, a swing arm 463 is fixedly connected to the rotating shaft 462, a pressing roller 464 is fixedly connected to the end of the swing arm 463 away from the rotating shaft 462, and the outer wall of the pressing roller 464 can contact the non-woven bag to press the non-woven bag. The pressing roller 464 is connected to the fixed seat 44 by a tension spring 465, so that the pressing roller 464 maintains a certain elasticity, so as to adapt to different heights of the non-woven bags after stacking.

[0050] The clamping assembly 46 also includes a driving component for driving the swing arm 463 to swing, specifically including a fixed plate 466, one end of the fixed plate 466 is fixedly connected to the support frame 5, a driving motor 467 is fixedly installed on the fixed plate 466, the output end of the driving motor 467 is fixedly connected to a rotating plate 468, a convex rod 469 is fixedly connected to the rotating plate 468, and a U-shaped plate 4610 is fixedly connected to the rotating shaft 462. After the convex rod 469 rotates a certain angle with the output shaft of the driving motor 467, it can enter the U-shaped plate 4610 and drive the rotating shaft 462 to rotate through the U-shaped plate 4610, thereby driving the swing arm 463 to swing clockwise by a certain angle, so that the pressure roller 464 is away from the stacked non-woven bags, so that new non-woven bags can continue to be stacked thereon. When the protruding rod 469 is separated from the U-shaped plate 4610, the swing arm 463 will automatically reset under the elasticity of the tension spring 465, so that the pressing roller 464 continues to press the stacked non-woven bags to prevent the non-woven bags from shifting due to machine vibration and other reasons.

[0051] As a preferred embodiment, the length of the pressing roller 464 is greater than the width of the non-woven bag, that is, greater than the distance between the two limit plates 453. When the pressing roller 464 swings counterclockwise with the swing arm 463, its two ends will contact the inclined surfaces on the two folding plates 41, and push the two folding plates 41 to both sides through the inclined surfaces, so that the two folding plates 41 move away from each other, thereby promoting the non-woven bag that is offset during the blanking process to enter between the vertical parts of the two folding plates 41, ensuring the smooth stacking of the non-woven fabric.

[0052] In addition, the correction mechanism 4 also includes a negative pressure box 43, which is fixedly connected to the correction disk 3. A plurality of negative pressure suction ports are opened on one side of the negative pressure box 43, and an exhaust fan is arranged inside the negative pressure box 43 to generate negative pressure in the negative pressure suction port to adsorb the non-woven bag.

[0053] The counting mechanism 6 includes a display module 61, which is fixedly mounted on the support frame 5 through a bracket, and the display module 61 is electrically connected to a counting trigger 62 and a zeroing trigger 63. The counting mechanism 6 also includes a fixing frame 64, which is fixedly connected to the support frame 5, and the counting trigger 62 and the zeroing trigger 63 are both mounted on the support frame 5. Among them, the counting trigger 62 is located on the motion track of the pressure roller 464, and when the pressure roller 464 swings clockwise at a certain angle, it can be released from the counting trigger 62 to trigger counting. The zeroing trigger 63 is located on the motion path of the support plate 461, and an inclined surface is set on the zeroing trigger 63 to change the transmission direction of the motion. In the process of the support plate 461 rotating with the turntable 22, it can contact the inclined surface and push the zeroing trigger 63 through the inclined surface to achieve giving way. In this process, the zeroing trigger 63 is triggered and the count on the display module 61 is reset.

[0054] The cutting mechanism 7 includes a telescopic driving member, which is fixedly connected to the support frame 5 via a connecting plate. A cutting knife is fixedly connected to the output end of the telescopic driving member for cutting and forming the non-woven bag in the correction disk 3 .

[0055] When the automatic deviation-correcting device for production and cutting of non-woven bags of the present invention is used, the drive motor 467 is started, and the output end of the drive motor 467 drives the protruding rod 469 to rotate through the rotating plate 468. After the protruding rod 469 rotates a certain angle, it can enter the U-shaped plate 4610, and drive the rotating shaft 462 to rotate through the U-shaped plate 4610, thereby driving the swing arm 463 to swing clockwise at a certain angle, so that the pressure roller 464 is away from the stacked non-woven bags, so that new non-woven bags can continue to be stacked thereon. When the protruding rod 469 is separated from the U-shaped plate 4610, the swing arm 463 will automatically reset under the elasticity of the tension spring 465, so that the pressure roller 464 continues to press the stacked non-woven bags tightly, preventing the non-woven bags from shifting due to mechanical vibration and other reasons. Each time the clamping assembly 46 is opened, the non-woven bags to be cut fall from the previous process into the deviation correction disk 3 for stacking. During the falling process, operational errors may occur, causing the non-woven bags to be stuck on the inclined part of the folding plate 41 and unable to fall. When the clamping assembly 46 is closed, the two ends of the pressure roller 464 will contact the inclined surfaces on the two folding plates 41, and push the two folding plates 41 to both sides through the inclined surfaces, so that the two folding plates 41 are separated from each other, thereby promoting the non-woven bags that are offset during the feeding process to enter between the vertical parts of the two folding plates 41, ensuring the smooth stacking of the non-woven fabrics.

[0056] When the pressing assembly 46 is opened, the pressing roller 464 presses the counting trigger 62 to make the counting mechanism 6 count the number of non-woven bags.

[0057] When the number of non-woven bags received on the deflection correction disk 3 reaches a preset number, the steering motor 21 is started, and the output end of the steering motor 21 drives the two deflection correction disks 3 to rotate 180 degrees through the turntable 22, so that the positions of the two deflection correction disks 3 are swapped. During the rotation of the deflection correction disk 3, the support plate 461 inside it will be driven to rotate synchronously. During the rotation of the support plate 461 with the turntable 22, the reset trigger 63 can be pressed to reset the count on the display module 61.
