Description

Technical Field

[0001] This utility model relates to the field of bag stacking machine technology, specifically to an automatic nylon bag stacking device. Background Technology

[0002] Nylon bags are bag-shaped containers made of nylon as the basic material. Nylon bags have a wide range of uses, covering many fields from daily necessities to industrial applications. In the production process, freshly produced nylon bags need to be folded to reduce their footprint and facilitate transportation, ensuring that workers can handle the bags properly.

[0003] Chinese Utility Model Patent Publication No. CN 211417837 U discloses a fully automatic bag folding machine. This machine connects to a longitudinal transmission mechanism and a transverse transmission mechanism via an electric cylinder and a rotary cylinder. It features automated operation, convenient operation, high efficiency, high folding quality, and easy maintenance. However, this automatic bag folding device lacks a flattening structure. When bending nylon bags, the unevenness of the bags can easily lead to inconsistent folding quality. Furthermore, the lack of a correction structure means that the nylon bags may shift during transport, affecting folding efficiency. Additionally, it cannot handle nylon bags of different widths, resulting in poor practicality. Summary of the Invention

[0005] The technical solution adopted by this utility model is: an automatic nylon bag stacking device, including an operating table and a frame.

[0006] Preferably, the flattening assembly includes a mounting base one, a cylinder one, a connecting column, a slot one, a pin, a pressing plate, a slot two, and a slot three. The mounting base one is fixedly installed at the bottom of the frame by bolts. The cylinder one is fixedly installed at the bottom of the mounting base one. The connecting column is fixedly installed at the movable end of the cylinder one. The connecting column has a slot one inside and a pin inside.

[0007] The above technical solution includes a flattening component. When the nylon bag passes directly under the flattening plate, cylinder one is activated, which pushes the flattening plate downward until the nylon bag is flattened before proceeding to the next step.

The first double-ended lead screw is adapted to the first sliding seat, and the first sliding seat and the first slide rail are slidably connected.

[0009] The above technical solution includes a correction component. When the nylon bag passes directly under the correction roller, cylinder two is activated.

Then, motor two is activated, and motor two drives sliding seat one to move on slide rail one, so that the correction roller on the sliding seat contacts the nylon bag and corrects its deviation, effectively preventing the nylon bag from becoming loose or shifting during the feeding process.

[0010] Preferably, there are two identical sliding seats, fixed columns, and correction rollers, which are symmetrically distributed about the center line of the double-headed lead screw. The correction rollers are adapted to the nylon bag body.

[0011] The above technical solution, through the cooperation of two sliding seats and a correction roller with the conveyor belt, enables the nylon bag to be effectively returned to its original position when it is misaligned or shifted, by the limiting action of the correction roller, thus improving its practicality.

[0013] The above technical solution incorporates a bending assembly. The user starts motor three, bringing the connecting block closer to the nylon bag. Once the bag reaches the designated position, cylinder three is activated, pushing the clamping head downwards to grip the nylon bag. When the rubber pad contacts the nylon bag, motor three is started again, pulling the bag directly above the rotating roller and bending plate. The clamping head is then released, allowing the bag to contact the rotating roller and bending plate. At this point, motor five is activated, flipping the bending plate to fold the nylon bag. This convenient operation effectively reduces the user's workload and improves work efficiency.

[0014] Preferably, there are multiple identical rotating rollers, and the rotating rollers and the bending plate are located on the same horizontal line.

[0015] The above technical solution improves the stability of nylon bags through the cooperation of multiple rotating rollers.

The user starts the motor 1102 to move the connecting block 1105 closer to the nylon bag. After reaching the designated position, the user starts the cylinder 1107 to push the clamping head 1108 downward to clamp the nylon bag. When the rubber pad 1109 contacts the nylon bag, the user starts the motor 1102 again to pull the nylon bag directly above the rotating roller 1112 and the folding plate 1122. Then the user releases the clamping head 1108 to let the nylon bag contact the rotating roller 1112 and the folding plate 1122. At this time, the user starts the motor 1121 to flip the folding plate 1122 and fold the nylon bag.

[0036] Specifically, multiple identical rotating rollers 1112 are provided, and the rotating rollers 1112 and the bending plate 1122 are located on the same horizontal line. The advantage is that the cooperation between multiple rotating rollers 1112 improves the stability of the nylon bag.

[0038] Working Principle: During use, the user starts motor 3, causing conveyor belt 6 to rotate. When the nylon bag passes directly under the pressing plate 906, conveyor belt 6 stops rotating. At this time, the user starts cylinder 902, which pushes the pressing plate 906 downwards until the nylon bag is flattened. Then, cylinder 902 drives the pressing plate 906 to retract. Motor 3 is started again, causing conveyor belt 6 to rotate. When the nylon bag passes directly under the straightening roller 1009, conveyor belt 6 stops rotating again. At this time, cylinder 1002 is started, pushing mounting plate 1003. Based on the length and width of the nylon bag, mounting plate 1003 is moved to the designated position. Then, motor 1005 is started, causing sliding seat 1007 to move on slide rail 1010, thus moving the straightening roller 1009 on the sliding seat. When the rubber pad 1109 contacts the nylon bag, it corrects its alignment. At this time, cylinder 1002 is activated again to retract the mounting plate 1003. Motor 1 is activated again to make the conveyor belt 6 rotate again. Finally, the user activates motor 3 1102 to move the connecting block 1105 closer to the nylon bag. After reaching the designated position, cylinder 3 1107 is activated to push the clamping head 1108 downward to clamp the nylon bag. When the rubber pad 1109 contacts the nylon bag, motor 3 1102 is activated again to pull the nylon bag directly above the rotating roller 1112 and the bending plate 1122. The clamping head 1108 is then released, allowing the nylon bag to contact the rotating roller 1112 and the bending plate 1122. At this time, motor 5 1121 is activated to flip the bending plate 1122, thus folding the nylon bag. The operation is convenient, thus completing the folding process for the nylon bag.
