Technical Field

[0001] The utility model relates to the technical field of plastic recycling, in particular to a waste plastic recycling and processing device. Background Art

[0002] Waste plastic refers to plastic waste after consumption. Due to its difficult-to-degrade nature, it has become one of the major sources of pollution that plagues people's daily lives. The best way to deal with waste plastic is to recycle it to the maximum extent possible. During the recycling process, the collected waste plastic needs to be pre-processed. The main process of pre-processing is to crush the waste plastic first, then wash, dehydrate and dry it.

[0003] In the prior art, waste plastics are usually pulverized by rotating a pulverizing roller. However, the size of the plastic debris after the pulverizing roller is pulverized cannot be adjusted. When smaller plastic debris needs to be pulverized, the waste plastic needs to be pulverized repeatedly, thereby increasing the labor intensity of the operator. In addition, the pulverized plastic debris is easily accumulated at the discharge port, causing the discharge pipe to be blocked, affecting the pulverization efficiency. Utility Model Content

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as Figures 1-6 As shown, the utility model provides a technical solution: a waste plastic recycling and processing device, including a box body 1, a feeding pipe 11 is fixedly connected to the top of the box body 1, a support 12 is fixedly connected to the bottom of the box body 1, a first motor 2 and a second motor 3 are fixedly installed on one side of the outer wall of the box body 1, the output end of the first motor 2 is fixedly connected to the first crushing roller 21, the output end of the second motor 3 is fixedly connected to the second crushing roller 31, the other side of the box body 1 is fixedly connected to the limited seat 4, the bottom of the box body 1 is fixedly connected to the material receiving box 5, the outer wall side of the material receiving box 5 is fixedly installed with a third motor 6, the bottom of the material receiving box 5 is fixedly installed with an exhaust fan 7, the other side of the material receiving box 5 is fixedly connected to a discharge pipe 8, the interior of the box 1 A mounting shaft 9 is provided, and two partitions 13 are fixedly connected to the top end of the inner wall of the box body 1, and two mounting brackets 14 are fixedly connected to the bottom end of the inner wall of the box body 1. A movable plate 15 is provided on the top of the two mounting brackets 14. The surface of the mounting shaft 9 is fixedly passed through the inside of the movable plate 15, and one side of the mounting shaft 9 is movably connected to the inner wall of the box body 1. A groove 401 is provided on the side of the limit seat 4, and one end of the surface of the mounting shaft 9 is fixedly connected to a positioning rod 91, which is movably installed in the inside of the groove 401. The bottom of the partition 13 is fixedly connected to the limiting block 16, and the inside of the partition 13 is provided with a card bead 17. The top of the card bead 17 is fixedly connected to a spring 18, and the spring 18 is fixedly connected to the inner wall of the partition 13.

[0025] In this embodiment, the waste plastic to be crushed is put into the feed pipe 11, and then the plastic falls to the top of the first crushing roller 21. The first motor 2 is started to drive the first crushing roller 21 to rotate to crush the plastic. The crushed plastic debris falls to the top of the second crushing roller 31. When the second motor 3 is started to drive the second crushing roller 31 to rotate, the plastic debris can be crushed for the second time, thereby reducing the size of the plastic debris. When the plastic debris does not need to be crushed for the second time, the movable plate 15 is driven to rotate by rotating the mounting shaft 9, so that the movable plates 15 on both sides rotate inward at the same time. At this time, the movable plates 15 on both sides are rotated. The top ends of the movable plate 15 are pressed against each other and cover the top of the second crushing roller 31, and the plastic debris slides directly from the top of the movable plate 15. The positioning rod 91 on the surface of the mounting shaft 9 is installed inside the groove 401, which can limit the rotation angle of the mounting shaft 9 and the movable plate 15 to prevent the movable plate 15 from rotating too much. When the inclined movable plate 15 is rotated to a vertical state, the cover of the second crushing roller 31 can be released. The movable plate 15 is located at the bottom of the partition 13, and the two ends of the movable plate 15 are respectively limited by the limit block 16 and the card bead 17, so that the movable plate 15 cannot rotate by itself, which is convenient for adjusting the size of the debris after the plastic is crushed.

[0026] Example 2, as Figures 1-6 As shown, the air inlet end of the exhaust fan 7 is connected to the interior of the material receiving box 5, a filter 51 is fixedly installed at the bottom end of the interior of the material receiving box 5, the output end of the third motor 6 is fixedly connected to a spiral blade 61, and one end of the surface of the spiral blade 61 is movably installed inside the discharge pipe 8.

[0027] In this embodiment, after the plastic debris is crushed, it falls to the bottom end of the box body 1. By starting the exhaust fan 7, suction is created inside the receiving box 5 to suck the debris into the receiving box 5 to prevent the debris from accumulating at the outlet and causing blockage. The filter 51 installed inside the receiving box 5 can separate the debris. By starting the third motor 6 to drive the spiral blade 61 to rotate, the plastic debris inside the receiving box 5 can be pushed into the discharge pipe 8 and discharged.

[0028] The working principle of this embodiment is as follows: the waste plastic to be crushed is put into the feed pipe 11, and then the first motor 2 is started to drive the first crushing roller 21 to rotate to crush the plastic. The crushed plastic debris falls to the top of the second crushing roller 31, and when the second motor 3 is started to drive the second crushing roller 31 to rotate, the plastic debris can be crushed for the second time. The movable plate 15 is driven to rotate by rotating the mounting shaft 9 so that the top ends of the movable plates 15 on both sides are against each other. At this time, the crushed plastic debris will fall from the side and will not be crushed for the second time. Then, the exhaust fan 7 is started to suck the debris into the material receiving box 5, and the third motor 6 is started to drive the spiral blade 61 to rotate, so that the plastic debris inside the material receiving box 5 can be pushed into the discharge pipe 8 and discharged, thereby completing the discharge of the plastic debris.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
