[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0021] Example 1

[0022] A cardboard cutting and processing waste recycling device, such as Figure 1-3 As shown, it includes a frame 1, a crushing roller 2 and a motor 3; a feed port is opened on the upper side of the frame 1; a discharge port is opened on the lower left side of the frame 1; the frame 1 is rotatably connected to two crushing rollers 2 distributed on the left and right, and the crushing rollers 2 crush the cardboard waste; the frame 1 is bolted to two motors 3 distributed on the left and right, and the output shaft of the motor 3 is fixedly connected to the corresponding crushing roller 2, and the motor 3 is used to drive the crushing roller 2 to rotate;

[0023] It also includes an arc-shaped mesh frame 4, a scraper 5 and a motor 2 6; the arc-shaped mesh frame 4 is arranged in the frame 1; the scraper 5 is rotatably connected in the frame 1, and the scraper 5 is in contact with the arc-shaped mesh frame 4; the frame 1 is bolted to the motor 2 6, and the output shaft of the motor 2 6 is fixedly connected to the scraper 5.

[0024] The feed inlet on the frame 1 is provided with two protection parts 1a distributed on the left and right, and the protection parts 1a are used to prevent the crushing roller 2 from causing harm to human beings.

[0025] The bottom of the frame 1 is provided with an inclined portion 1 b for guiding the shredded cardboard waste to the feeding port on the frame 1 .

[0026] The specific operation of the above-mentioned embodiment 1 is as follows: first, the cardboard waste is manually placed between the two crushing rollers 2 through the feeding port on the frame 1, and at the same time, the output shafts of the two motors 1 3 are controlled to drive the corresponding crushing rollers 2 to rotate, so that the two crushing rollers 2 cooperate to crush the cardboard waste, thereby crushing the cardboard waste into pulverized cardboard waste;

[0027] When the cardboard waste is crushed into pulverized cardboard waste, the pulverized cardboard waste will fall onto the inner side of the arc-shaped mesh frame 4, and the pulverized cardboard waste will be screened by the arc-shaped mesh frame 4, so that the pulverized cardboard waste smaller than the mesh of the arc-shaped mesh frame 4 will fall to the inner bottom of the frame 1, and then under the influence of the inclined portion 1b, the pulverized cardboard waste smaller than the mesh of the arc-shaped mesh frame 4 will move toward the discharge port on the frame 1, and finally fall to the outside through the discharge port on the frame 1, while the pulverized cardboard waste larger than the mesh of the arc-shaped mesh frame 4 will still be on the inner side of the arc-shaped mesh frame 4, thereby completing the screening of the pulverized cardboard waste;

[0028] It should be noted that, in the process of the arc-shaped screen frame 4 screening the crushed cardboard waste, the mesh of the arc-shaped screen frame 4 is easily blocked by the crushed cardboard waste, which leads to frequent shutdown to clear the blocked mesh, thus resulting in low overall crushing efficiency;

[0029] Therefore, in the process of screening the crushed cardboard waste, the following is taken as a reference from front to back, and the output shaft of the control motor 2 6 drives the scraper 5 to rotate ninety degrees clockwise first to prepare, and then the output shaft of the control motor 2 6 drives the scraper 5 to rotate one hundred and eighty degrees counterclockwise, and then the output shaft of the control motor 2 6 drives the scraper 5 to rotate one hundred and eighty degrees clockwise, and so on. The rotation is repeated, so that the rotating scraper 5 pushes the crushed cardboard waste blocked in the grid of the arc-shaped mesh frame 4 to move downward, thereby completing the dredging of the grid of the arc-shaped mesh frame 4, thereby avoiding the problem of frequent shutdowns to dredge the blocked grid.

[0030] Example 2

[0031] On the basis of Example 1, Figure 1-4 As shown, it also includes a secondary crushing assembly; the frame 1 is connected to two secondary crushing assemblies distributed on the left and right, and each secondary crushing assembly is connected to the arc-shaped mesh frame 4, and the secondary crushing assembly is used to perform secondary crushing on the crushed cardboard waste supported on the scraper 5; the secondary crushing assembly includes a crushing knife 1 101, a mounting plate 102, a crushing knife 2 103 and a motor 3 104; the arc-shaped mesh frame 4 is fixedly connected to a plurality of crushing knives 101; the frame 1 is rotatably connected to the mounting plate 102; the mounting plate 102 is fixedly connected to a plurality of crushing knives 2 103; the frame 1 is bolted to the motor 3 104, and the output shaft of the motor 3 104 is fixedly connected to the mounting plate 102.

[0032] The crushing blade 1 101 and the crushing blade 2 103 are arranged in a staggered distribution, and this arrangement is used to enable the crushing blade 101 and the crushing blade 2 103 to better perform secondary crushing on the crushed cardboard waste supported on the scraper 5 .

[0033] The specific operation of the above-mentioned embodiment 2 is as follows: It should be noted that in the embodiment 1, when the motor 2 6 drives the scraper 5 to rotate clockwise by 180 degrees, the rotating scraper 5 will scrape the crushed cardboard waste that is larger than the grid of the arc-shaped net frame 4 on its left side and move together. After the scraper 5 rotates clockwise by 180 degrees, the left side of the scraper 5 will support the crushed cardboard waste that is larger than the grid of the arc-shaped net frame 4. It should be noted that the following is the working process of the left secondary crushing component. At this time, the following is based on the view from the front to the back. The output shaft of the control motor 3 104 drives the mounting plate 102 and the crushing knife 2 103 to rotate clockwise by 90 degrees. In this process, the crushing knife 2 103 will push the crushed cardboard waste supported on the left side of the scraper 5 to gather in the direction close to the crushing knife 1 101, and as the crushing knife 2 103 continues to rotate, the crushing knife 1 101 cooperates with the crushing knife 2 103 to perform secondary crushing on the crushed cardboard waste supported on the left side of the scraper 5.

[0034] When the crushed cardboard waste supported on the left side of the scraper 5 has completed secondary crushing, the control motor 3 104 drives the mounting plate 102 and the crushing knife 2 103 to restore the initial position. In this process, the cardboard waste that has completed secondary crushing will fall back onto the scraper 5. When the motor 2 6 drives the scraper 5 to rotate 180 degrees counterclockwise, the cardboard waste that has completed secondary crushing will fall onto the arc-shaped mesh frame 4, and then the arc-shaped mesh frame 4 will screen the cardboard waste that has completed secondary crushing again.

[0035] After the motor 2 6 drives the scraper 5 to rotate counterclockwise by 180 degrees, the right side of the scraper 5 will also support the crushed cardboard waste that is larger than the mesh of the arc-shaped mesh frame 4, and then the right secondary crushing component is controlled to perform secondary crushing on the crushed cardboard waste supported on the right side of the scraper 5 in the same way as above;

[0036] After the crushed cardboard waste is screened by the arc-shaped mesh frame 4, the scraper 5 enables the crushing knife 1 101 and the crushing knife 2 103 to continuously perform secondary crushing on the crushed cardboard waste that is larger than the mesh of the arc-shaped mesh frame 4, thereby avoiding the problem in the prior art that the second crushing roller is difficult to completely ensure that all the screened crushed cardboard waste is crushed into a specified size.

[0037] Example 3

[0038] On the basis of Example 2, Figure 2 and Figure 4 As shown, scraping bars 201 are also included; each mounting plate 102 is fixed with a plurality of scraping bars 201 for cleaning cardboard waste stuck between two adjacent crushing teeth on the crushing roller 2, and each scraping bar 201 is located between two adjacent crushing teeth on the corresponding crushing roller 2.

[0039] The specific operation of the above-mentioned embodiment 3 is as follows: It should be noted that in embodiment 1, during the crushing operation of the crushing roller 2 on the cardboard waste, part of the cardboard waste will be stuck between two adjacent crushing teeth on the crushing roller 2. When too much cardboard waste is stuck on the crushing roller 2, the normal operation of the crushing roller 2 will be affected;

[0040] Therefore, by arranging the scraper bar 201 on the mounting plate 102 so that the scraper bar 201 cleans the cardboard waste stuck between two adjacent crushing teeth on the crushing roller 2, the problem of affecting the normal operation of the crushing roller 2 when too much cardboard waste is stuck on the crushing roller 2 can be avoided.

[0041] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
