Description

Technical Field

[0001] This utility model relates to the field of ton bag production technology, and in particular to a blower-stacked bag device. Background Technology

[0002] A common type of air-blowing bag folding device is used for folding plastic bags. It mainly includes a frame, a folding mechanism, a storage template, and an air-blowing mechanism. The storage template is used to place the plastic bags to be folded. The air-blowing mechanism is located between the folding mechanism and the storage template. When the plastic bag to be folded is placed on the storage template, the air-blowing mechanism blows air into the plastic bag in the vertical direction. Since the storage template only supports the middle of the plastic bag, the four edges of the plastic bag are suspended. The air blowing can bend the ends of the plastic bag relative to the storage template. Then the folding mechanism can fold the bent plastic bag, thus solving the problem of unsuccessful mechanical folding when the plastic bag is too hard. The device includes a bag opening folding machine, a pressing mechanism, a folding spade mechanism, and a folding air-blowing pipe. The bag opening folding machine has a bag opening folding station for placing the cut pieces to be folded. The pressing mechanism drives the pressing plate through the pressing driver to press the cut pieces to be folded on the bag opening folding station.

The bag opening folding device includes a bag opening folding machine, a pressing mechanism, a folding scraper mechanism, and a folding air blower. The bag opening folding machine has a bag opening folding station for placing the cut piece to be folded. The pressing mechanism includes a pressing driver and a pressing plate; the pressing driver is connected to the pressing plate to drive the pressing plate to press down on the cut piece to be folded at the bag opening folding station. The folding scraper mechanism includes a scraper driver and a folding scraper; the scraper driver is connected to the folding scraper to drive the folding scraper to extend above the edge of the pressing plate. The upper side of the folding scraper is recessed to form a receiving groove, and the folding air blower is disposed in the receiving groove for blowing air out of the receiving groove. The aforementioned bag opening folding device can improve the automation level of bag opening folding, is easy to operate, saves labor costs, and improves product stability. However, although the device can improve product stability, it cannot fold inwards, which increases the labor intensity of manual folding and reduces work efficiency. Utility Model Content

[0030] Working principle: First, place the bag to be folded on the tray 201. Then, insert one end of the ventilation pipe 402 into the bag to inflate it. Under the action of the blower 401, the bag will inflate. Then, start the cylinder 501. The cylinder 501 moves downward, which drives the push column 502 to press down on the compression plate 206. At this time, the upper hinge 204 and lower hinge 205 on both sides of the compression plate 206 fold. At the same time, the cylindrical slider 2072 will move downward along the guide column 2071 with the compression plate 206, pressing the upper pressure plate 203 and lower pressure plate 202 tightly against the outer wall of the bag. At this time, the bag will be squeezed into shape by the upper pressure plate 203 and lower pressure plate 202. Then, close the cylinder 501. At this time, the compression plate 206 will spring back upward, and at the same time, it will drive the upper pressure plate 203 and lower pressure plate 202 to spring back, thus realizing the function of quickly folding and storing the bag. First, the fixing plate 304, along with the blower 401, is placed on the threaded rod 301. At this time, the blower 401 will compress the first spring 302. The fixing plate 304 will then be supported on the top of the threaded cap 303. The threaded cap 303 is then screwed onto the threaded rod 301 to fix the fixing plate 304. When the blower 401 is started, it will vibrate. This vibration is transmitted to the first spring 302 through the threaded rod 301. The compression and tension of the first spring 302 buffer the vibration. At the same time, the sliding column 3051 will slide inside the cylindrical sleeve 3053, compressing the second spring 3052. This allows the blower 401 to be disassembled and replaced, while also providing a buffering effect.
