[0021] Specifically, pusher assembly 2 includes mounting bracket 2-1 arranged on workbench 1, mounting bracket 2-1 is arranged on workbench 1, and electric cylinder 2-2 is arranged on mounting bracket 2-1, the output end of electric cylinder 2-2 is equipped with folding plate mounting seat 2-3, folding plate mounting seat 2-3 is used to install folding plate 3, and folding plate mounting seat 2-3 and folding plate 3 are moved to contact plastic bag by starting electric cylinder 2-2, so that plastic bag is sent into strip-shaped mouth 4 for folding.

[0022] Specifically, the conveying assembly 5 includes two conveying rollers 5-1 that are rotatably mounted on the workbench 1. The shaft ends of the two conveying rollers 5-1 are provided with first gears 5-2 that mesh with each other. The workbench 1 is provided with a first drive motor 5-3 that drives one of the first gears 5-2 to rotate. In use, by starting the first drive motor 5-3, one gear 5-2 is driven to rotate. One gear 5-2 drives the other first gear 5-2 to rotate in the opposite direction. The relative rotation of the two first gears 5-2 drives the two conveying rollers 5-1 to rotate relative to each other, thereby realizing the conveying of plastic bags.

[0023] Specifically, the adjustable sensing device 7 includes a lead screw module 7-1 mounted on the workbench 1, with a sensor 7-2 at the moving end of the lead screw module 7-1. During the first and second folds in the horizontal direction, the lead screw module 7-1 is activated to drive the sensor 7-2 to adjust according to the length of the plastic bag. In the vertically folding section, the distance between the sensor 7-2 and the strip opening 4 is half the length of the plastic bag. In the horizontally folding section, the distance between the sensor 7-2 and the strip opening 4 is one-quarter the length of the plastic bag. During the first and second folds in the vertical direction, the lead screw module 7-1 is activated to drive the sensor 7-2 to adjust according to the width of the plastic bag. The longitudinally arranged folding section has the sensor 7-2 adjusted to the middle of the plastic bag's width. When the sensor 7-2 detects a deviation between the middle of the plastic bag and the middle of the strip opening 4, the position of the plastic bag is adjusted by the worktable 1 to make the middle of the plastic bag coincide with the middle of the strip opening 4. The transversely arranged folding section has the distance between the sensor 7-2 and the strip opening 4 being one-quarter of the plastic bag's width. This allows the position of the plastic bag to be set by the adjustable sensing device 7, so that the plastic bag folds according to the length position set by the adjustable sensing device 7.

Several transmission rollers 6-2 are provided on the side wall of the rotating rods 6-1. A transmission belt 6-3 is provided between the transmission rollers 6-2 on the same side of the rotating rods 6-1. The shaft ends of the pair of rotating rods 6-1 are provided with second gears 6-4 that mesh with each other. The workbench 1 is provided with a second drive motor 6-5 that drives one of the second gears 6-4 to rotate. In use, the second drive motor 6-5 is started to drive one of the second gears 6-4 to rotate. The rotation of one of the second gears 6-4 drives the other gear 6-4 to rotate in the opposite direction. The two second gears 6-4 drive the rotating rods 6-1 and the several transmission rollers 6-2 on the upper and lower sides to rotate relative to each other. The transmission rollers 6-2 on the rotating rod 6-1 are connected to the several transmission rollers 6-2 on other rotating rods 6-1 by transmission belts 6-3, which realizes the relative rotation of the transmission belts 6-3 on the upper and lower sides, and realizes the conveying of plastic bags.

[0025] Working principle: When the plastic bag is being conveyed on the workbench 1, the adjustable sensing device 7 is activated according to the length of the plastic bag to set the folding position. When folding horizontally, the pushing component 2 of the longitudinal folding part is activated to drive the folding plate 3 downward, so that the plastic bag passes through the strip opening 4 and enters the conveying component 5 for the first folding. When the conveying component 5 conveys the plastic bag to the set position, the pushing component 2 of the transverse folding part is activated to drive the folding plate 3 downward, so that the plastic bag passes through the strip opening 4 and enters the conveying component 6 to enter another set of folding bag exiting structures. The above operation is repeated to perform longitudinal folding, ensuring the quality of the plastic bag exiting the bag.
