Technical Field

[0001] The utility model relates to the technical field of urea bag recovery, in particular to a urea packaging bag recovery mechanism. Background Art

[0002] With the development of agricultural production, urea has been widely used as an important nitrogen fertilizer. Urea bags have become an indispensable packaging material during the production, transportation, and use of urea. To pour the urea from a urea bag, a cutter is typically used to slash one side of the bag, allowing the urea to fall through. The bag is then removed for collection.

[0003] Existing equipment has the following drawbacks: Traditional urea bag recycling methods rely heavily on manual labor, resulting in low efficiency and high costs. Furthermore, urea bags often contain residual urea after use. If not effectively processed, this not only wastes resources but also potentially pollutes the environment.

[0004] In response to the above problems, this paper proposes a urea packaging bag recycling mechanism, which aims to improve the recycling efficiency and processing quality of urea bags through automation and mechanization.

[0005] Therefore, the present application proposes a urea packaging bag recycling mechanism to solve the above-mentioned problems. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-6 The utility model provides a technical solution: a urea packaging bag recovery mechanism, comprising a conveying unit 1 for conveying a urea bag 2, a mounting frame 6 provided on one side of the conveying unit 1, and a guide plate 3 provided on a side of the conveying unit 1 close to the mounting frame 6, and further comprising:

[0026] The screening device 4 is provided on one side of the conveying unit 1 close to the guide plate 3 and is used to screen the residue in the urea bag 2;

[0027] A cleaning device 5 is provided on the mounting frame 6 and near the lower end of the guide plate 3, and is used to clean the urea bag 2;

[0028] The second collecting frame 8 is provided below the mounting frame 6 and is used for collecting impurities.

[0029] The urea bag 2 is placed on the conveying unit 1 with the opening facing downward, and then transported to one side of the guide plate 3 through the conveying unit 1, and then slides onto the guide plate 3. At this time, the screening device 4 is started, and after the urea bag 2 is fixed, it is screened to shake off the urea and impurities remaining in the urea bag 2, and then the urea bag 2 falls onto the mounting rack 6, and is cleaned and squeezed by the cleaning device 5 on the mounting rack 6, so that the urea bag 2 can be further cleaned, and the cleaned urea residue and impurities fall into the interior of the second collecting frame 8 for collection. The cleaning device 5 can squeeze the uneven urea bag 2 to reduce its occupied space and facilitate subsequent collection and transportation. By arranging the conveying unit 1, the screening device 4 and the cleaning device 5, a fully automated process from conveying to screening to cleaning of the urea bag 2 is realized, which greatly improves the recycling efficiency and reduces the labor cost. The urea bag 2 can be effectively recycled and processed, reducing the generation of waste and reducing the impact on the environment, which is in line with the current green and environmental protection development concept.

[0030] In one embodiment, the screening device 4 includes a power member 41 arranged on the conveying unit 1 and symmetrically arranged about the guide plate 3, a connecting rod 42 arranged at the power output end of the power member 41, a connecting plate 43 arranged on the connecting rod 42, a vacuum suction cup 45 arranged on the side of the connecting plate 43 close to the guide plate 3, and an air pump 44 fixed on the connecting plate 43 and connected to the vacuum suction cup 45. The connecting plate 43 can be adjusted and arranged above the guide plate 3.

[0031] This design, see Figure 1-6 When a urea bag 2 falls onto the guide plate 3, the conveying unit 1 pauses, and the power member 41 drives the connecting plate 43 to move closer to the side of the urea bag 2, so that the vacuum suction cup 45 squeezes the urea bag 2, and then turns on the air pump 44, so that the vacuum suction cup 45 adsorbs and fixes the urea bag 2. The power member 41 drives the connecting plate 43 to move up and down to screen the urea bag 2. The opening of the urea bag 2 faces downward, and the residue remaining in the urea bag 2 can be shaken out, which can effectively remove the residue in the urea bag 2 and provide convenience for subsequent reuse.

[0032] In one embodiment, the cleaning device 5 includes a motor 51 arranged on one side of the mounting frame 6, a rotating shaft 52 arranged at the power output end of the motor 51, a first cleaning roller 53 fixed on the rotating shaft 52, a connecting shaft 552 arranged at the lower end of the mounting frame 6 and a second cleaning roller 55 fixed on the rotating shaft 52, and the rotating shaft 52 is connected to the second cleaning roller 55 through a transmission member 54.

[0033] This design, see Figure 3-6The motor 51 drives the rotating shaft 52 to rotate, thereby driving the first cleaning roller 53 and the second cleaning roller 55 to roll, so that the urea bag 2 can be quickly cleaned when passing between the first cleaning roller 53 and the second cleaning roller 55, thereby improving the cleaning efficiency. The first cleaning roller 53 and the second cleaning roller 55 can squeeze the urea bag 2, reducing the space occupied by the urea bag 2 and facilitating subsequent recycling and transportation.

[0034] In one embodiment, the transmission member 54 includes a first gear 541 fixed on the rotating shaft 52, a second gear 543 fixedly mounted on the connecting shaft 552, and a gear belt 542 mounted on the first gear 541 and the second gear 543, and the gear belt 542 is meshed and connected with the first gear 541 and the second gear 543.

[0035] This design, see Figure 5 Through the meshing connection of the first gear 541, the second gear 543 and the gear belt 542, the transmission member 54 can achieve stable and continuous transmission, ensuring the synchronous rotation between the rotating shaft 52 and the second cleaning roller 55, thereby maintaining the smooth progress of the cleaning process.

[0036] In one embodiment, the first cleaning roller 53 is provided with a first brush 531 , and the second cleaning roller 55 is provided with a second brush 551 .

[0037] This design, see Figure 1-6 The design of the first brush 531 and the second brush 551 increases the contact area and friction between the first cleaning roller 53 and the second cleaning roller 55 and the surface of the urea bag 2, thereby more effectively removing dirt, impurities and residues on the urea bag 2 and improving the thoroughness and efficiency of cleaning.

[0038] In one embodiment, a feed port 601 is provided at the position of the mounting frame 6 corresponding to the first cleaning roller 53 and the second cleaning roller 55, and an inclined filter screen 61 is provided inside the feed port 601. A first collecting frame 7 for collecting the urea bag 2 is provided on the side of the filter screen 61 away from the first cleaning roller 53 of the mounting frame 6.

[0039] This design, see Figure 4-6 The design of the feed port 601 enables the urea bag 2 to enter the cleaning area between the first cleaning roller 53 and the second cleaning roller 55 in an orderly manner. The inclined filter screen 61 can be intercepted when the urea bag 2 enters the cleaning area, so that the urea bag 2 is transported at the upper end of the filter screen 61, and then after being squeezed by the first cleaning roller 53 and the filter screen 61, the urea bag 2 moves to one side of the first collecting frame 7 under the push of the first brush 531, and then falls into the first collecting frame 7 through the inclined filter screen 61 for collection.

[0040] In addition, if there are descriptions of "first," "second," etc. in the embodiments, such descriptions are for descriptive purposes only and should not be understood as indicating or implying the relative importance of the description or implicitly indicating the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features.
