Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to a single packaging bag feeding mechanism. Background Technology

[0002] Packaging bags are widely used in the packaging of bulk materials such as grains, fertilizers, feed, building materials, and chemical raw materials. For example, the most commonly used woven bags are usually stored in multiple stacks before entering the automatic packaging line. Before subsequent automatic bag opening, filling, and sealing processes, the stacked packaging bags need to be separated one by one, continuously, reliably, and correctly oriented, and transported to the designated workstation.

[0003] For a long time, this process has relied mainly on manual material loading. Operators need to constantly bend over or turn around, laboriously pulling individual woven bags from the stacks and accurately placing them onto the conveyor equipment or gripping station. Manual extraction and placement are slow and extremely labor-intensive, making it difficult to match the production pace of modern high-speed packaging lines, thus becoming a key factor restricting overall efficiency improvement. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing an automated, efficient, and easy-to-operate single-feeding mechanism for packaging bags.

[0005] This utility model is achieved through the following technical solution: a single feeding mechanism for packaging bags is provided, including a feeding frame, a placement plate, and two parallel circulating chains. A conveyor belt is connected between the two circulating chains and surrounds the placement plate. The mechanism also includes a feeding suction cup frame and a feeding suction cup cylinder for driving the feeding suction cup frame to rise and fall. The feeding suction cup frame is equipped with multiple feeding pneumatic suction cups, and the conveyor belt has a feeding port for the feeding suction cup frame and the packaging bag to pass through.

[0006] This solution uses a feeding suction cup cylinder to extend and lower the feeding suction cup frame through the feeding port to above one end of the packaging bag. The feeding pneumatic suction cup then adsorbs the end of the top layer of packaging bag. The feeding suction cup cylinder then retracts, lifting one end of the packaging bag above the feeding port. The circulating chain moves, causing the upper layer of the conveyor belt to move to the left, laying the packaging bag flat on the conveyor belt. At the same time, the feeding pneumatic suction cup is released, thus achieving flat feeding of a single packaging bag on the conveyor belt.

[0007] As an optimization, a feeding pusher is also included to horizontally push the packaging bags on the placement plate to below the feeding port. The feeding pusher in this solution can horizontally push the packaging bags on the placement plate to below the feeding port, thus eliminating the need for workers to place stacked packaging bags below the feeding port, making it easier for workers to place the packaging bags.

[0008] As an optimization, two feeding pushers are provided, and the placement plate has pusher slots adapted to the feeding pushers. In this solution, the packaging bag is pushed by two feeding pushers, and the pusher slots do not affect the placement of the packaging bag.

[0009] As an optimization, the feeding push rod is vertically fixed to the push rod moving frame, which is located below the placement plate. A feeding cylinder is installed below the placement plate to drive the push rod moving frame to move horizontally. In this design, the feeding cylinder drives the push rod moving frame, thereby moving the feeding push rod.

[0010] As an optimization, the circulating chain bypasses the quadrilaterally arranged drive sprocket, first sprocket, second sprocket, and third sprocket, and also includes a conveyor belt motor that drives the drive sprocket to rotate. In this solution, the cyclic movement of the circulating chain is achieved by the rotation of the drive sprocket.

[0011] As an optimization, the two drive sprockets are connected by a sprocket shaft, and the conveyor belt motor drives the sprocket shaft to rotate via a power transmission belt. In this design, the two drive sprockets rotate synchronously via the sprocket shaft.

[0012] As an optimization, a vertical suction cup guide post is fixedly connected to the feeding suction cup frame, and a suction cup guide sleeve mounting plate is fixedly connected to the feeding frame. A suction cup guide sleeve adapted to the suction cup guide post is fixedly connected to the suction cup guide sleeve mounting plate. In this solution, the suction cup guide sleeve guides the suction cup guide post, thereby guiding the feeding suction cup frame through the suction cup guide post.

[0013] The beneficial effects of this utility model are as follows:

[0014] By combining an innovative pneumatic suction cup for feeding with a conveyor belt with a feeding port, the system ensures stable and reliable separation and extraction of the top layer of packaging bags each time, significantly reducing the failure rate of double or multiple bags sticking together or jamming.

[0015] It completely replaces the cumbersome manual feeding operation, realizing continuous, fast, and unmanned feeding of packaging bags, greatly improving the overall production cycle and capacity of the packaging line, and meeting the needs of large-scale industrial production.

[0016] It significantly reduces labor costs and labor intensity, completely eliminates the heavy physical labor of manually picking up and placing woven bags, saves at least one operator, directly reduces labor costs and improves workers' working conditions, which is especially significant in harsh (dust, odor) environments.

Detailed Implementation

[0025] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0026] like Figures 1-6 As shown, a single packaging bag feeding mechanism of this utility model includes a feeding frame 1, a placement plate 13 and two parallel circulating chains 2. The feeding frame 1 is the supporting skeleton of the entire feeding mechanism, which is generally composed of profile welding or bolt connection. The placement plate 13 is a horizontal metal plate. Workers place multiple stacked packaging bags 23 on the placement plate 13. The placement plate 13 is equipped with feeding side baffles 17 on both sides.

[0027] Two circular chains are arranged side by side, such as... Figure 3 As shown, the circulating chain passes around the quadrilaterally arranged drive sprocket 4, first sprocket 10, second sprocket 11, and third sprocket 12, and also includes a conveyor belt motor 9 that drives the drive sprocket 4 to rotate. Thus, the rotation of the drive sprocket 4 drives the circulating chain 2 to move. In this embodiment, the two drive sprockets 4 are connected by a sprocket shaft 5, and the conveyor belt motor 9 drives the sprocket shaft 5 to rotate via a power transmission belt 7. Figure 2 , 3 As shown, a drive pulley 8 is fixedly connected to the shaft of the conveyor belt motor 9, a driven pulley 6 is fixedly connected to the shaft of the sprocket 5, and a power transmission belt 7 connects the driven pulley 6 and the drive pulley 8.

[0028] The first sprocket 10 and the second sprocket 11 are at the same height and located above each other, while the drive sprocket 4 and the third sprocket 12 are at the same height and located below each other, thereby causing the circulating chain between the first sprocket 10 and the second sprocket 11 to move horizontally.

[0029] A conveyor belt 3 connects the two circulating chains 2. In this embodiment, the conveyor belt 3 is a stainless steel mesh belt, and the circulating chains 2 are 10A chains. The conveyor belt 3 surrounds the placement plate 13, meaning that one end of the placement plate 13 is inserted between the upper and lower conveyor belts 3, allowing multiple stacked packaging bags to be moved below the upper conveyor belt 3. In this embodiment, the other end of the placement plate 13 extends to the outside of the conveyor belt 3, allowing workers to place the stacked packaging bags at this end for easy placement.

[0030] It also includes a feeding pusher 14 that horizontally pushes the packaging bag on the placement plate 13 to a position below the feeding port. There are two feeding pushers 14, and the placement plate 13 has pusher grooves that are adapted to the feeding pushers 14. The distance between the two feeding pushers 14 is less than the length of the packaging bag, so that the packaging bag is pushed to a position directly below the upper conveyor belt 3 by the two feeding pushers 14.

[0031] like Figure 2 , 3 As shown, the feeding push rod 14 is vertically fixed to the push rod moving frame 15, which is located below the placement plate 13. Two slide rails are fixed to the lower end face of the placement plate 13, and a slider is installed on the push rod moving frame 15, thereby realizing the sliding guidance of the push rod moving frame 15. A feeding cylinder 16 is installed below the placement plate 13 to drive the push rod moving frame 15 to move horizontally.

[0032] It also includes a feeding suction cup frame 19 and a feeding suction cup cylinder 18 that drives the feeding suction cup frame 19 to rise and fall. The feeding suction cup cylinder 18 extends and retracts vertically downwards. In order to guide the lifting and lowering of the feeding suction cup frame 19, a vertical suction cup frame guide post 21 is fixedly connected to the feeding suction cup frame 19. A suction cup frame guide sleeve mounting plate is fixedly connected to the feeding frame 1. A suction cup frame guide sleeve 22 that is adapted to the suction cup frame guide post 21 is fixedly connected to the suction cup frame guide sleeve mounting plate. The suction cup frame guide sleeve 22 guides the suction cup frame guide post 21.

[0033] The feeding suction cup frame 19 is equipped with a plurality of feeding pneumatic suction cups 20. In this embodiment, two feeding pneumatic suction cups 20 are provided.

[0034] like Figure 2As shown, the conveyor belt 3 has a feeding port for the feeding suction cup frame 19 and the packaging bag to pass through, so that the feeding suction cup frame 19 and the feeding pneumatic suction cup 20 can pass through the feeding port to suck up one end of the packaging bag to the top surface of the conveyor belt 3. In this embodiment, the conveyor belt 3 is segmented, specifically two segments, with the feeding port formed between the two adjacent segments. Therefore, there are two feeding ports in total. After one end of the packaging bag is lifted to the top surface of the conveyor belt 3, the edge of the conveyor belt pushes the packaging bag to make the packaging bag lie flat on the top surface of the conveyor belt.

[0035] How to use this utility model:

[0036] In use, multiple packaging bags are stacked on the placement plate 13. The packaging bags are pushed to below the feeding port by the feeding push rod 14. The feeding suction cylinder 18 extends downward, driving the feeding suction cup frame 19 to pass through the feeding port and descend to above one end of the packaging bag. The feeding pneumatic suction cup 20 then adsorbs the end of the top layer of packaging bag. Figure 3 (as shown in the diagram), then the feeding suction cylinder 18 retracts, lifting one end of the packaging bag above the feeding port ( Figure 4 As shown in the diagram, the circulating chain 2 moves, causing the upper layer of the conveyor belt 3 to move to the left, laying the packaging bag flat on the conveyor belt 3. Figure 5 (as shown in the diagram), while the pneumatic suction cup 20 is released, thus realizing the flat feeding of a single packaging bag on the conveyor belt 3.
