Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste bag recycling technology, specifically to a waste bag recycling device. Background Technology
[0002] Waste bag recycling devices can be used on bag-making production lines. Connected to the rear discharge stage of the bag-making machine, these devices can promptly collect and recycle defective bags caused by printing defects, inaccurate cutting dimensions, poor heat sealing, etc., preventing them from scattering in the production workshop. This facilitates centralized processing and maintains the cleanliness and orderliness of the workshop. They can also be used in automatic filling machines in the food and chemical industries. After products are filled into packaging bags, sometimes the bags leak or break, becoming waste bags. Installing a waste bag recycling device next to the filling machine allows for the rapid removal of these problematic bags from the production line, preventing leaked materials from polluting the equipment and workshop environment, while ensuring the smooth operation of the entire filling process.
[0003] Existing waste bag recycling devices typically use motor-driven screw shafts for screw conveying, which can meet the need for continuous waste bag conveying. However, waste bags often get tangled on the screw shaft, preventing them from being output. This not only affects the efficiency of waste bag conveying and recycling but may also cause the screw shaft to become entangled with other parts of the equipment, affecting the operation and safety of the equipment. In addition, some waste bags containing contaminants will leave residue inside the conveying equipment, contaminating important components and affecting their service life and normal operation. Utility Model Content
[0004] To solve the above-mentioned problems, this utility model proposes a waste bag recycling device that can continuously and stably transport waste bags, has residue cleaning and component protection functions, and avoids waste bags from contaminating important structures.
[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a waste bag recycling device, comprising:
[0006] The outer conveyor cylinder has a waste bag outlet at one end, a waste bag inlet at the top, and several fixed support legs at the bottom.
[0007] The feeding control mechanism is located at the waste bag inlet and includes a movable baffle hinged at the waste bag inlet and an electric push rod that drives the movable baffle to rotate.
[0008] The pusher assembly is slidably disposed inside the outer conveying cylinder, and includes a rigid pusher and a flexible sealing ring. The bottom surface and side wall of the rigid pusher are in contact with the inner wall of the outer conveying cylinder and are driven by an electric slide fixed to one side of the outer conveying cylinder. The flexible sealing ring is disposed at the contact point between the rigid pusher and the outer conveying cylinder.
[0009] The hook plate is fixedly installed inside the outer cylinder of the conveyor and near the waste bag outlet.
[0010] Furthermore, a feed trough is fixedly provided at the inlet of the waste bag, and the movable baffle and the electric push rod are both hinged in the feed trough, with the end of the electric push rod hinged to the movable baffle.
[0011] Furthermore, the upper edge of the feed trough is inclined outward.
[0012] Furthermore, the electric slide is provided with a slider driven by it, the slider extends into the outer conveying cylinder and is connected and fixed to the pusher assembly, the outer conveying cylinder is provided with a through groove for the slider to slide on the side wall, and brushes are provided on the upper and lower walls of the through groove.
[0013] Furthermore, a camera electrically connected to an external display screen is fixedly mounted above the rigid push plate.
[0014] Furthermore, the hook plate is fixedly installed on the upper inner wall of the outer conveying cylinder, and its lower end is inclined toward the waste bag outlet.
[0015] Compared with the prior art, the advantages of this invention are as follows: the upper edge of the feed trough in the device is inclined outward, which allows the waste bags to enter more smoothly, avoids jamming, and improves feeding efficiency. Furthermore, the movable baffle in the feeding control mechanism is driven by an electric push rod, which can precisely control the timing of the waste bags entering the outer conveying cylinder, while not affecting the continuous feeding of waste bags into the feed trough, ensuring orderly feeding.
[0016] The rigid pusher plate of the pusher assembly fits snugly against the inner wall of the outer conveyor cylinder and is stably driven by an electric slide table. This allows for direct ejection of waste bags, preventing entanglement. A flexible sealing ring is also installed at the contact point between the rigid pusher plate and the outer conveyor cylinder to reduce gaps between them. Simultaneously, it removes residue adhering to the waste bags and remaining inside the outer conveyor cylinder, preventing contamination and damage to the internal structure. Brushes on the upper and lower walls of the through-slot automatically open and close to accommodate the slider movement. This ensures smooth slider movement while preventing residue from entering the through-slot and damaging the electric slide table, providing excellent component protection.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.
[0024] Combined with appendix Figure 2 Appendix Figure 4 A waste bag recycling device includes: a conveying outer cylinder 1, with a waste bag outlet at one end, a waste bag inlet at the top, and several fixed support legs 2 at the bottom. A feeding trough 8 is fixedly provided at the waste bag inlet. The upper edge of the feeding trough 8 is inclined outward, which facilitates the smooth entry of waste bags into the feeding trough 8, avoids the waste bags getting stuck at the upper edge, and improves the feeding efficiency.
[0025] Combined with appendix Figure 3 Appendix Figure 5 The feeding control mechanism is located at the waste bag inlet and includes a movable baffle 3 hinged at the waste bag inlet and an electric push rod 4 that drives the movable baffle 3 to rotate. Both the movable baffle 3 and the electric push rod 4 are hinged in the feeding trough. The end of the electric push rod 4 is hinged to the movable baffle 3, which can play a good guiding and controlling role in feeding the waste bag and ensure that it falls stably and orderly into the outer conveying cylinder 1.
[0026] Combined with appendix Figure 2 Appendix Figure 4 Appendix Figure 5 The pusher assembly, slidably disposed inside the outer conveying cylinder 1, includes a rigid pusher 5 and a flexible sealing ring. The bottom surface and side wall of the rigid pusher 5 are in contact with the inner wall of the outer conveying cylinder 1. The flexible sealing ring is disposed at the contact point between the rigid pusher 5 and the outer conveying cylinder 1. The rigid pusher 5 is driven by an electric slide table 6 fixedly disposed on one side of the outer conveying cylinder 1. The electric slide table 6 is provided with a slider 9 driven by it. The slider 9 extends into the outer conveying cylinder 1 and is connected and fixed to the pusher assembly. The side wall of the outer conveying cylinder 1 is provided with a through groove 10 for the slider 9 to slide. The upper and lower walls of the through groove 10 are provided with brushes 11. The through groove 10 can guide the slider 9 to ensure that it drives the pusher assembly to move stably and push out the waste bag. The brushes can prevent residue from entering the through groove 10 and have a good protective effect on the electric slide table 6. At the same time, it can also adapt to the movement of the slider 9 and automatically open and close to ensure the smooth movement of the slider 9.
[0027] Combined with appendix Figure 4 Appendix Figure 5The hook plate 7 is fixedly installed inside the outer conveying cylinder 1 and near the waste bag outlet. The hook plate 7 is fixedly installed on the upper inner wall of the outer conveying cylinder 1, and its lower end is inclined towards the waste bag outlet, which can more effectively guide the waste bag to the waste bag outlet, ensure that the waste bag can be discharged smoothly, and effectively prevent the waste bag from returning to the outer cylinder with the pusher assembly.
[0028] Combined with appendix Figure 2 Appendix Figure 5 A camera 12, which is electrically connected to an external display screen, is fixedly installed above the rigid push plate 5 to facilitate real-time monitoring of the working status of the rigid push plate 5 and the conveying status of waste bags and residues in the outer conveying cylinder 1, so as to take timely action and prevent waste bags or residues from causing damage to components.
[0029] The specific implementation method of this utility model is as follows: First, the outer conveyor cylinder 1 is fixed on the production line frame so that the falling waste bags can fall into the feeding trough 8, and the device is connected to an external power source. When the waste bags fall, because the upper edge of the feeding trough 8 is inclined outward, the waste bags can enter the feeding trough 8 more smoothly, avoiding jamming at the upper edge and ensuring feeding efficiency.
[0030] Next, the feeding control mechanism begins to function. The electric push rod 4 drives the movable baffle 3, which is hinged at the waste bag inlet, to rotate and adjust its angle. This precisely controls the timing of the waste bag entering the outer conveying cylinder 1. When the waste bag needs to fall into the outer conveying cylinder 1, the extended end of the movable baffle 3 can be tilted downwards, and the waste bag falls along the movable baffle 3 into the outer conveying cylinder 1. When no feeding is needed in the outer conveying cylinder 1, the extended end of the movable baffle 3 can be tilted upwards, so that the waste bag is temporarily stored in the feeding trough 8. In this way, the waste bag is controlled to fall into the outer conveying cylinder 1 in a regular and intermittent manner.
[0031] Then, after the waste bag enters the outer conveyor cylinder 1, the electric slide 6 fixed to one side of the outer conveyor cylinder 1 starts to work. The electric slide 6 drives the slider 9 to slide along the through groove 10 on the side wall of the outer conveyor cylinder 1. The brushes 11 on the upper and lower walls of the through groove 10 will automatically open and close as the slider 9 moves, which can not only ensure the smooth movement of the slider 9, but also prevent residue from entering the through groove 10 and avoid damage to the electric slide 6. The slider 9 drives the rigid push plate 5 in the push plate assembly to move back and forth in the outer conveyor cylinder 1. The bottom surface and side wall of the rigid push plate 5 are in contact with the inner wall of the outer conveyor cylinder 1. The flexible sealing ring at the contact point reduces the gap. The rigid push plate 5 pushes the waste bag falling into the outer conveyor cylinder 1 toward the waste bag outlet. In this process, the residue falling into the outer conveyor cylinder 1 can also be pushed out. By controlling the speed at which the electric slide 6 pushes the rigid push plate 5 to match the speed of the movable baffle, the continuous and stable ejection of waste bags can be achieved.
[0032] Finally, the hook plate 7 located near the waste bag outlet has its lower end tilted towards the waste bag outlet, which can more effectively guide the waste bag to be discharged smoothly and prevent the waste bag from returning to the outer cylinder with the pusher assembly. The camera 12 above the rigid pusher 5 can monitor the working status and other conditions in real time and display the feedback to the monitoring personnel through the display screen, so as to deal with the waste bags or residues remaining in the outer cylinder 1 in a timely manner.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto.
