Description

Technical Field

[0001] This utility model relates to the field of scrap recycling devices, specifically a scrap recycling device for composite paper can production. Background Technology

[0002] Composite paper cans are packaging containers made of multiple materials such as paper, plastic, and metal. A large amount of scrap material is generated during the production process. If it is not effectively recycled, it will not only waste resources but also increase the environmental protection costs of enterprises and even cause a series of environmental problems. However, the scrap material generated on the production line is mostly irregular in shape, and manual sorting is time-consuming and labor-intensive. Therefore, most enterprises choose to crush the scrap material first and then separate the waste materials of different materials in the scrap material through separation equipment.

[0003] In the prior art, utility model patent CN202221889552.9 discloses a scrap recycling device for composite paper can production, relating to the field of waste recycling technology. Addressing the inconvenience of recycling scrap from composite paper can production, the following solution is proposed: It includes a cover, with a crushing box fixedly connected to the upper side of the cover. The crushing box is open at both the top and bottom. Several inclined plates are fixedly connected to the upper side of the cover, which is also open, and these inclined plates are located below the crushing box. Symmetrically distributed rotating shafts pass through the inside of the crushing box. A motor is fixedly connected to the outside of the cover. This scrap recycling device for composite paper can production has a crushing mechanism to crush the scrap, facilitating subsequent recycling. The device also has a compression mechanism that drives a collection box to reciprocate horizontally. Combined with the fixed plates, this compresses the fragments scattered in the collection box, facilitating subsequent collection and improving work efficiency. The scrap recycling device provided by the aforementioned patent, by setting a compression mechanism, can compress the crushed scrap, further reducing the volume of the debris, making it easier for workers to transport it to the next processing equipment. However, the scrap recycling device does not screen the crushed scrap fragments during use, which leads to some large scraps that are not crushed or are poorly crushed being mixed into the scrap fragments, resulting in poor scrap crushing effect and affecting the effect of subsequent waste separation and processing.

The crushing roller 301 can be driven to rotate by the first motor 302, and the gear set 303 can make a set of crushing rollers 301 rotate synchronously relative to each other to crush scrap materials. Crushing blades are provided on the crushing roller 301 to crush scrap materials.

[0024] like Figure 1 , Figure 3 and Figure 4As shown, it also includes a screening box 2, a pneumatic conveying pump 7, and an air pump 9. The crushing box 1 is installed on the screening box 2. The crushing box 1 is installed on the screening box 2 so that the crushed scraps can fall into the screening box 2. The screening box 2 is inclinedly equipped with a screening device 4. The screening device 4 includes a mounting frame 401 and a screen plate 403. A first support spring 402 is provided on one side of the upper end face of the mounting frame 401, and a second support spring 405 is provided on the other side. The screen plate 403 is movably installed on the upper end face of the mounting frame 401 through the first support spring 402 and the second support spring 405. A vibrator 404 is provided on the screen plate 403. The sieve plate 403 is inclinedly mounted on the mounting frame 401 by a first support spring 402 and a second support spring 405. The first and second support springs 402 and 405 were selected through multiple experiments to support the sieve plate 403 and allow it to sway, preventing it from being fixed and thus ensuring good screening results. The vibrator 404 can then drive the sieve plate 403 to shake. The mounting frame 401 is horizontally positioned and installed inside the screening box 2. The first support spring 402 is higher than the second support spring 405. A first receiving trough 5 is located on the side of the screening box 2 corresponding to the lowest point of the screening device 4, and a second receiving trough 6 is located at the bottom of the screening box 2 below the screening device 4. The screen plate 403 can be tilted by the first support spring 402 being higher than the second support spring 405. When scraps fall onto the screen plate 403, qualified scraps can fall through the screen plate 403 into the second receiving trough 6, while unqualified scraps fall into the first receiving trough 5 as the screen plate tilts.

[0025] like Figure 3 and Figure 6As shown, the inlet of the pneumatic conveying pump 7 is connected to the inside of the first receiving trough 5, and the outlet is located above the crushing device 3, penetrating the body of the crushing box 1.

The dust-suppressing filter cylinder 8 also includes a rotating shaft 802, which is rotatably installed in the dust-suppressing filter cylinder 8. The upper end of the rotating shaft 802 penetrates the upper body of the dust-suppressing filter cylinder 8 and is connected to a second motor 803. The lower end of the rotating shaft 802 penetrates the lower body of the dust-suppressing filter cylinder 8 and is provided with a cleaning brush 804, which abuts against the filter holes 801 at the lower end of the dust-suppressing filter cylinder 8. The inlet of the air pump 9 is connected to the inside of the dust-suppressing filter cylinder 8, and the outlet is connected to a dust-suppressing water tank 10. A ventilation port 805, connecting to the inside of the dust-suppressing filter cartridge 8, is located on the side outside the crushing chamber 1. The air inlet of the air pump 9 is connected to the ventilation port 805. By setting up the dust-suppressing filter cartridge 8, the air pump 9 can prevent scrap material debris from being sucked up when absorbing dust inside the crushing chamber 1. At the same time, a cleaning brush 804 is rotated inside the dust-suppressing filter cartridge 8 to clean the filter holes 801 at the lower end of the dust-suppressing filter cartridge 8 in a timely manner, preventing the scrap material debris sucked up from clogging the filter holes 801.

[0027] like Figure 2 , Figure 3 and Figure 5 As shown, a scrap recycling device for composite paper can production includes a crushing box 1, a crushing device 3 inside the crushing box 1, and a feeding port 101. The feeding port 101 is located on the side of the crushing box 1, on the crushing device 3, and a dust cover 102 is rotatably mounted on the feeding port 101. The crushing device 3 includes crushing rollers 301 and a gear set 303. A pair of crushing rollers 301 are rotatably mounted inside the crushing box 1, and the pair of crushing rollers 301 rotate synchronously through the gear set 303. One end of one of the crushing rollers 301, away from the gear set 303, passes through the crushing box 1 and is connected to a first motor 302.

[0028] like Figure 1 , Figure 3 and Figure 4As shown, the system also includes a screening box 2, a pneumatic conveying pump 7, and an air pump 9. A crushing box 1 is mounted on the screening box 2. A screening device 4 is inclinedly arranged inside the screening box 2. The screening device 4 includes a mounting frame 401 and a screen plate 403. A first support spring 402 is provided on one side of the upper end face of the mounting frame 401, and a second support spring 405 is provided on the other side. The screen plate 403 is movably mounted on the upper end face of the mounting frame 401 via the first support spring 402 and the second support spring 405. A vibrator 404 is provided on the screen plate 403. The mounting frame 401 is horizontally positioned, with the first support spring 402 higher than the second support spring 405. A first receiving trough 5 is provided on the side of the screening box 2 corresponding to the lowest position of the screening device 4, and a second receiving trough 6 is provided at the bottom of the screening box 2 below the screening device 4.

[0029] like Figure 3 and Figure 6 As shown, the inlet of the pneumatic conveying pump 7 is connected to the inside of the first receiving trough 5, and the outlet is installed above the crushing device 3, penetrating the body of the crushing box 1. A dust-suppressing filter cylinder 8 is installed on the crushing box 1. The upper end of the dust-suppressing filter cylinder 8 is closed, and the lower end extends into the crushing box 1 and is provided with filter holes 801. The dust-suppressing filter cylinder 8 also includes a rotating shaft 802, which is rotatably installed within the dust-suppressing filter cylinder 8. The upper end of the rotating shaft 802 penetrates the upper body of the dust-suppressing filter cylinder 8 and is connected to a second motor 803. The lower end of the rotating shaft 802 penetrates the lower body of the dust-suppressing filter cylinder 8 and is provided with a cleaning brush 804, which abuts against the filter holes 801 at the lower end of the dust-suppressing filter cylinder 8. The inlet of the air pump 9 is connected to the inside of the dust-suppressing filter cylinder 8, and the outlet is connected to a dust-suppressing water tank 10. The side of the dust filter cartridge 8 is provided with a ventilation port 805 that connects to the inside of the dust filter cartridge 8 at a position outside the crushing box 1, and the air inlet of the air pump 9 is connected to the ventilation port 805.

[0030] The working principle of this utility model is as follows: During use, scrap materials are put into the crushing box 1, and then the dust cover 102 is closed to start the crushing operation. During crushing, the air pump 9 absorbs the dust floating inside the crushing box 1, and the dust filter cylinder 8 prevents the scrap material debris from being sucked away by the air pump 9. At the same time, the cleaning brush 804 is installed in the dust filter cylinder 8 to clean the filter hole 801 at the lower end of the dust filter cylinder 8 in time, preventing the scrap material debris sucked up from clogging the filter hole 801. The air pump 9 transports the absorbed dust to the dust water tank 10 to prevent the dust from floating away again. At the same time, the crushed scrap material debris is filtered through the screen plate 403. The qualified debris can fall through the screen plate 403 into the second receiving trough 6 for collection, and the unqualified debris falls into the first receiving trough 5 as the screen plate tilts. The unqualified debris in the first receiving trough 5 is then transported to the crushing box 1 for further crushing by the pneumatic conveying pump 7.

[0031] In summary, this utility model, by setting a screening device 4, separates the crushed debris into qualified and unqualified portions. The unqualified portion is then transported to the crushing chamber 1 by a pneumatic conveying pump 7 for further crushing. This allows for automatic multiple crushing of the unqualified debris, thereby improving the crushing effect. The dust-suppressing filter cylinder 8 prevents the simultaneous suction of crushed scrap debris when the air pump 9 absorbs dust inside the crushing chamber 1. Furthermore, the cleaning brush 804 on the dust-suppressing filter cylinder 8 prevents clogging. The above are merely preferred embodiments of this utility model and are not intended to limit its scope. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within its protection scope.
