[0002] The three-side seal packaging machines are all equipped with a silo for storing packaging bags. The existing silos are all single-silo structures. The suction cups suck the packaging bags from the bottom of the silo and directly transport them to the bag opening mechanism for bag opening. Since the front, back, left and right positions of the packaging bags are not uniform when they are stacked in the silo after being made, the success rate of transporting them to the bag opening machine for opening is low, which in turn affects the production efficiency of the packaging machine. Summary of the invention

[0003] The purpose of the present invention is to provide a double-layer bag bin structure, which solves the problem in the prior art that when the packaging bags are placed in a silo and stacked, the front, back, left, and right positions of the packaging bags are not uniform, resulting in a low success rate in conveying the bags to a bag opening machine for opening, thereby affecting the production efficiency of the packaging machine.

[0007] Furthermore, the front end of the push plate is arranged in a "V"-shaped opening.

[0008] Furthermore, the driving mechanism includes a push rod, a push rod seat, a connecting plate, a linear rail and a cylinder, the front end of the push rod is connected to the push plate, the rear end of the push rod is connected to the push rod seat, the push rod seat is connected to the connecting plate, the linear rail is arranged on both sides of the bracket, and the two ends of the connecting plate are slidably supported by the linear rail; the output end of the cylinder is connected to one end of the connecting plate for driving the connecting plate to move along the linear rail.

[0009] Furthermore, the bag suction mechanism also includes a hollow column and a power source, the pull rod is slidably sleeved in the hollow column, and the power source is used to drive the pull rod to rise and fall along the hollow column.

[0010] The present invention provides a double-layer bag bin structure, in which finished packaging bags are stacked in the storage bag bin, a pull rod of the bag suction mechanism rises, driving a first suction cup to suck the packaging bags on the bottom layer of the storage bag bin from a first opening, and then the pull rod descends and resets, and the sucked packaging bags are placed on a bag receiving plate, and then the bag pushing mechanism works to drive the pushing plate to push forward once and then reset, and in the process of pushing forward, the packaging bags on the bag receiving plate are pushed into a channel between an upper guide plate and the bag receiving plate, and one end of the packaging bags touches the positioning plate for end face positioning, and after the pushing plate is reset, the packaging bags pushed into the channel are flat due to their own tension. The bags are laid on the bag receiving plate and aligned on both sides by the side guide plates. Then, the pull rod rises and the second suction cup absorbs the already positioned packaging bags in the sorting bag bin from the second opening. Synchronously, the first suction cup absorbs the bottom packaging bags in the storage bag bin. Then, the pull rod descends and the packaging bags on the second suction cup are taken away by the bag taking mechanism. The packaging bags on the first suction cup are put into the sorting bag bin for sorting again. This cycle is repeated. The sorting and positioning of the sorting bag bin ensures that each packaging bag picked up by the bag taking mechanism is aligned through sorting, thereby ensuring the uniform position of each packaging bag, improving the success rate of bag opening and ensuring the production efficiency of the packaging machine.

The sorting bag bin 3 includes a side guide plate 301, an upper guide plate 302, a bag receiving plate 303 and a positioning plate 304. The side guide plates 301, the upper guide plate 302, the bag receiving plate 303 and the positioning plate 304 can realize the positioning and sorting of the packaging bags in the front, back, left and right directions to ensure that the position of the packaging bags is uniform each time. The side guide plates 301 are arranged on both sides of the bag receiving plate 303, the upper guide plate 302 is arranged parallel to the bag receiving plate 303 and a channel 306 for accommodating packaging bags is provided therebetween, the positioning plate 304 is arranged at the rear end of the channel 306, and the front of the upper guide plate 302 The end of the bag is provided with an upwardly curved guide portion 305, so that when the packaging bag moves forward on the bag receiving plate 303 under the action of the bag pushing mechanism 4, the guide portion 305 ensures that the packaging bag can smoothly enter the channel 306 and the front end of the packaging bag in the forward direction abuts the positioning plate 304, so as to prevent the packaging bag from floating and affecting the positioning effect when it moves forward; the bag pushing mechanism 4 includes a push plate 401 and a driving mechanism for driving the push plate 401 to move, the push plate 401 is arranged at the front end of the channel 306 and is used to push the packaging bag into the channel 306; the bag suction mechanism 5 includes a pull rod 501 and a mounting plate 502 arranged at the upper end of the pull rod 501, and the mounting plate 502 is provided with a first suction cup 503 and a second suction cup 504 in sequence, and the first suction cup 50 3 is located just below the first opening, the second suction cup 504 is located just below the second opening, and when the adsorption surface of the first suction cup 503 reaches the first opening of the storage bag bin 2, the adsorption surface of the second suction cup 504 reaches the second opening of the sorting bag bin 3, so that it can be ensured that when the first suction cup 503 is sucking the packaging bags in the storage bag bin 2, the second suction cup 504 can synchronously suck the packaging bags in the sorting bag bin 3, and two suction actions are realized through a set of power mechanism, which greatly improves the production efficiency, and the structure is simple and does not interfere with each other. In this embodiment, as a preferred embodiment, the first suction cup 503 and the second suction cup 504 each include at least two suction cups acting on the same packaging bag synchronously to ensure the stability of the packaging bag during the suction process.

[0019] Specifically, the finished packaging bags are stacked in the storage bag bin 2, and the pull rod 501 of the bag suction mechanism 5 rises, driving the first suction cup 503 to suck a packaging bag from the bottom layer of the storage bag bin 2 from the first opening, and then the pull rod 501 is lowered and reset, releasing the sucked packaging bag onto the bag receiving plate 303 of the sorting bag bin 3, and then the bag pushing mechanism 4 works to drive the pushing plate 401 to push forward and reset, and in the process of pushing forward, the packaging bag on the bag receiving plate 303 is pushed into the channel 306 between the upper guide plate 302 and the bag receiving plate 303, and one end of the packaging bag touches the positioning plate 304 for end face positioning, and after the pushing plate 401 is reset, the packaging bag pushed into the channel is flattened on the bag receiving plate 303 due to its own tension, and pushed in Since the packaging bags in the channel 306 have their own tension, the two sides of the packaging bags are aligned by the side guide plate 301, and then the pull rod 501 rises, and the second suction cup 504 sucks the packaging bags that have been positioned in the sorting bag bin 3 from the second opening. Synchronously, the first suction cup 503 sucks a packaging bag at the bottom layer of the storage bag bin 2, and then the pull rod 501 descends, and the packaging bag on the second suction cup 504 is taken away by the bag picking mechanism. At the same time, the packaging bag on the first suction cup 503 is released again to the sorting bag bin 3 for sorting, and this cycle is repeated. The sorting and positioning of the sorting bag bin 3 ensures that each packaging bag picked up by the bag picking mechanism is aligned through sorting, thereby ensuring that the position of each packaging bag is unified, improving the success rate of bag opening, and ensuring the production efficiency of the packaging machine.

[0020] In order to facilitate the push plate 401 to better push the packaging bag into the channel 306, in this embodiment, the front end of the push plate 401 is preferably set to a "V"-shaped opening, and the edge of the packaging bag is just located in the "V"-shaped opening. In this way, the packaging bag is prevented from being offset during the pushing process of the push plate 401.

The driving mechanism has a simple structure, can be easily realized by driving through the cylinder 406, and has accurate positioning consistency.

[0022] The bag suction mechanism 5 in this embodiment also includes a hollow column 505 and a power source. The pull rod 501 is slidably mounted in the hollow column 505. The power source is used to drive the pull rod 501 to move up and down along the hollow column 505.
