[0026] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.
[0027] like Figures 1 to 5 As shown, the packaging bag unpacking machine of this utility model includes a first support 1, on which a feeding mechanism is provided; a second support 10, located on one side of the first support 1, on which a guide plate 11, a film tearing mechanism, a film collecting mechanism 18, a discharge plate 19, and a main control box 9 are provided; the feeding mechanism is used to feed the material wrapped in the packaging bag to the guide plate 11; the guide plate 11 is used to guide the material wrapped in the packaging bag to the film tearing mechanism; the film tearing mechanism is used to tear off the packaging bag wrapped in the material and to guide the material with the torn packaging bag to the discharge plate 19 for discharge; the film collecting mechanism 18 is used to collect the packaging bag torn off by the film tearing mechanism. This setup, through the cooperation of the feeding mechanism, guide plate 11, film tearing mechanism, film receiving mechanism 18, and unloading plate 19, constitutes a mechanically automated production line for unpacking material packaging bags, replacing the traditional manual unpacking method which is time-consuming, labor-intensive, and inefficient, thus saving labor and improving efficiency.
[0028] The bag-opening machine is operated through the main control box 9, making it easy to use.
[0029] In practical applications, this utility model is mainly applicable to the opening of fruit packaging bags. Therefore, the following description will use fruit as the material.
[0030] Furthermore, the feeding mechanism includes a hopper 2 and a feeding rack 3. The feeding end of the feeding rack 3 is correspondingly arranged with the hopper 2, and the discharging end of the feeding rack 3 is correspondingly arranged with the guide plate 11. The hopper 2 is driven to vibrate by a first driving device, so that the material in the hopper 2 is fed onto the feeding rack 3. The feeding rack 3 is provided with a conveyor belt 5, which is driven to rotate by a second driving device, so that the material on the conveyor belt 5 is fed onto the guide plate 11. In this configuration, the material (fruit) wrapped in a packaging bag is poured into the hopper 2, the hopper 2 is driven to vibrate by the first driving device, so that the material (fruit) in the hopper 2 is fed onto the feeding rack 3, and then fed onto the guide plate 11 via the conveyor belt 5, thus achieving the purpose of feeding.
[0031] Furthermore, the first end of the hopper 2 is hinged to the first support 1; the first driving device includes a first motor 4, an eccentric wheel 20, and a connecting rod. The output end of the first motor 4 is connected to the eccentric wheel 20, the eccentric wheel 20 is connected to the first end of the connecting rod, and the second end of the connecting rod is connected to the second end of the hopper 2. With this configuration, when the first motor 4 operates, it drives the eccentric wheel 20 to rotate. When the eccentric wheel 20 rotates, it causes the first end of the connecting rod to move around the eccentric wheel 20, thereby causing the second end of the connecting rod to pull the second end of the hopper 2 to move, achieving the purpose of vibration.
[0032] Furthermore, the second drive device includes a second motor 6, a drive sprocket 7, a driven sprocket 71, and a chain 21. The output end of the second motor 6 is connected to the drive sprocket 7. The drive sprocket 7 and the driven sprocket 71 are located at the discharge end and the feed end of the feeding rack 3, respectively. The chain 21 is wound around the drive sprocket 7 and the driven sprocket 71, and the chain 21 is fixedly connected to the conveyor belt 5. With this configuration, when the second motor 6 is working, it drives the drive sprocket 7 to rotate. When the drive sprocket 7 rotates, it drives the chain 21 and the driven sprocket 71 to rotate. When the chain 21 rotates, it drives the conveyor belt 5 to rotate, thereby achieving the purpose of conveying materials (fruit).
[0033] Furthermore, the discharge end of the feeding rack 3 is equipped with a first short-bristled brush roller 8, which is located above the conveyor belt 5. The feeding rack 3 is equipped with a first adjusting member 22 for adjusting the height of the first short-bristled brush roller 8. This arrangement prevents the material (fruit) from piling up. Specifically, the distance between the first short-bristled brush roller 8 and the conveyor belt 5 can be adjusted to match the size of a single material (fruit). Thus, when the material (fruit) is piled up and passes by, the first short-bristled brush roller 8 will sweep the material off.
[0034] Furthermore, the conveyor belt 5 is inclined, with its lower end connected to the hopper 2 and its higher end connected to the first end of the guide plate 11, and the second end of the guide plate 11 connected to the film-tearing mechanism. The conveyor belt 5 is composed of multiple parallel rollers, and a limiting groove for limiting the material is formed between adjacent rollers. This arrangement ensures that the material (fruit) is conveyed from bottom to top during feeding, preventing damage. Specifically, if the material is conveyed from top to bottom, it may roll, easily causing damage. The limiting groove between the rollers ensures more stable feeding of the material (fruit) and prevents it from flowing back into the hopper 2.
[0035] Furthermore, the film-tearing mechanism includes double baffles 15, double spiral rollers 16, a fourth motor 23, a double short-bristle brush roller assembly, and a mounting base 24; the mounting base 24 is fixed on the second bracket 10, the double baffles 15 are symmetrically arranged on the mounting base 24, the double spiral rollers 16 are arranged side by side between the double baffles 15, the double spiral rollers 16 are driven to rotate relative to each other by the fourth motor 23, the double short-bristle brush roller assembly is located above the double spiral rollers 16, the double spiral rollers 16 and the double short-bristle brush roller assembly cooperate to tear off the packaging bag of the material located on the double spiral rollers 16, the double spiral rollers 16 are correspondingly provided with double long-bristle brush rollers 17; the film-collecting mechanism 18 is located below the double spiral rollers 16. With this setup, when the film is peeled off, the material (fruit) is located between the double helical roller 16 and the double short-bristle brush roller assembly. The double short-bristle brush roller assembly and the double helical roller 16 work together to limit or clamp the material (fruit) and prevent it from bouncing upwards. At the same time, the fourth motor 23 drives the double helical roller 16 to rotate relative to each other (specifically, the two helical rollers rotate towards the middle), which can roll the outer packaging bag of the material (fruit) into the space between the double helical rollers 16, thereby peeling the material (fruit) out of the packaging bag. Meanwhile, under the rotation of the helical components of the double helical roller 16, the material (fruit) is conveyed to the feeding plate 19 for feeding.
[0036] The double long-bristle brush roller 17 is attached to the double spiral roller 16 and can sweep off the packaging bags wrapped on the double spiral roller 16 during the rotation of the double spiral roller 16; the film collection mechanism 18 is located below the double spiral roller 16 and serves to collect the packaging bags.
[0037] Furthermore, the dual short-bristle brush roller assembly includes a second short-bristle brush roller 12, a third short-bristle brush roller 13, a third motor 14, and a slide block 25. The slide block 25 is adjustablely positioned on the mounting base 24, and the third motor 14 is fixed to the slide block 25. The output end of the third motor 14 is connected to the third short-bristle brush roller 13. The second short-bristle brush roller 12 is height-adjustable on the slide block 25 via a second adjusting member 29. This configuration allows for pre-adjustment of the slide block 25's position on the mounting base 24 according to the size of the material (fruit), thereby adjusting the distance between the third short-bristle brush roller 13 and the double spiral roller 16. When the material (fruit) is positioned between the double spiral roller 16 and the third short-bristle brush roller 13, the third motor 14 drives the third short-bristle brush roller 13 to rotate while the bag is being torn, thus pushing the material (fruit) towards the lower material plate 19; assisting the double spiral roller 16 in conveying the material (fruit) and improving feeding efficiency.
[0038] The double spiral roller 16 is made of rubber to avoid damage to the material; the second short brush roller 12 is located between the third short brush roller 13 and the guide plate 11, which can buffer the material (fruit) guided down from the guide plate 11 and prevent it from being stacked and damaged.
[0039] Furthermore, a fixing frame 30 is fixed on the mounting base 24. The fixing frame 30 includes a guide post 27, and a guide block 28 is fixed on the slide 25. The guide block 28 is slidably connected to the guide post 27. The fixing frame 30 is provided with a rotatable second adjusting member 26, which is threadedly connected to the slide 25. With this configuration, the vertical displacement of the slide 25 can be controlled by rotating the second adjusting member 26 to generate threaded movement with the slide 25. In particular, under the sliding connection between the guide block 28 and the guide post 27, the vertical displacement of the slide 25 is more stable and will not deviate.
[0040] Furthermore, the film collecting mechanism 18 includes a first fixing block 31, a second fixing block 32, a scraper 33, and a spring 34. The first fixing block 31 and the second fixing block 32 are fixed parallel to each other on the mounting base 24. The scraper 33 is movably located between the first fixing block 31 and the second fixing block 32, and the scraper 33 is correspondingly arranged with the double spiral roller 16. The two ends of the spring 34 are respectively fixed to the scraper 33 and the mounting base 24. The second fixing block 32 is provided with a limiting plate 35, and the limiting plate 35 is provided with a third adjusting member 36 for adjusting the height position of the scraper 33. With this arrangement, the scraper 33 can scrape the packaging bags on the double spiral roller 16, and with the double long-bristle brush roller 17, the scraping effect can be improved. The scraped packaging bags are then collected.
[0041] The tension of the spring 34 allows the scraper 33 to fit better against the double helical roller 16; the third adjusting member 36 can adjust the height of the scraper 33, making assembly more convenient; there are two scrapers 33, each corresponding to the double helical roller 16.
