Description

Technical Field

[0001] This utility model belongs to the field of plastic recycling and processing, and in particular relates to a crushed plastic sorting and screening device. Background Technology

[0002] Plastic recycling refers to the process of collecting, sorting, processing, and reprocessing waste plastic products (such as packaging materials, daily necessities, and industrial scraps) to restore their usability. Crushing and processing of plastic products is a key step in plastic recycling, breaking down waste plastics into small particles or fragments through mechanical force, laying the foundation for subsequent washing, sorting, and melt granulation.

[0003] However, existing plastic fragment sorting equipment usually uses air separation, which achieves material stratification and separation by the difference between airflow force and gravity. However, when the above equipment is used, there is usually a problem of uneven material distribution, which makes it difficult for plastic fragments to be pushed by airflow to achieve separation when feeding. It usually requires multiple sorting to ensure the sorting effect, which is inefficient, time-consuming and labor-intensive. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 4 This utility model provides a crushed plastic sorting and screening device, comprising:

[0027] The machine casing 1 has a feed inlet 11 fixedly opened at its upper end, and a funnel-shaped guide hopper 12 is fixedly installed inside the casing at the position corresponding to the feed inlet 11.

[0028] Bulk assembly 2, used to disperse plastic scraps, includes:

[0029] Mounting bracket 21 is horizontally set inside the housing 1, and multiple support springs 22 are fixedly mounted on it;

[0030] The machine base 23 is mounted on the mounting frame 21 by a support spring 22. Multiple drive rollers 25 are rotatably mounted inside the machine base 23. A conveyor belt 26 is wrapped around the outside of the multiple drive rollers 25. Multiple vibration motors 27 are fixedly mounted at the bottom of the machine base 23.

[0031] A drive motor 24 is fixedly mounted on the side of the machine base 23, and its power output end is fixedly connected to the shaft end of a drive roller 25. The drive motor 24 is used to drive the drive roller 25 and the conveyor belt 26 to rotate.

[0032] The fan 3 is used for air separation of plastic scraps. It is fixedly installed in the housing 1 by the mounting rod 31. An air inlet 14 is fixedly opened on the side of the housing 1 corresponding to the position of the fan 3. An air outlet 15 is fixedly opened on the other side of the housing 1. A partition plate 16 is fixedly installed in the housing 1 corresponding to the position below the fan 3.

[0033] In practical application, plastic scraps are added into the housing 1 through the feed inlet 11 and fall onto the conveyor belt 26 under the guidance of the guide hopper 12. The vibration motor 27 is started, and the elastic support of the support spring 22 realizes the overall vibration of the machine base 23. The drive motor 24 drives the drive roller 25 to rotate, which in turn drives the conveyor belt 26 to rotate. The vibration of the vibration motor 27 makes the material evenly spread on the surface of the conveyor belt 26. After the material moves to the edge and falls off, the fan 3 realizes the air separation of the material, and the partition plate 16 is used as a partition to realize the layer separation of the plastic scraps.

[0034] In this embodiment, the material distribution component 2, under the elastic support of the support spring 22, works in conjunction with the vibration motor 27 to drive the machine base 23 to vibrate, thereby dispersing the material piled on the conveyor belt 26. Compared with existing sorting equipment, the sorting effect is better, thus eliminating the need for a large number of repetitive sorting operations and greatly improving work efficiency.

[0035] Please see Figure 2 and Figure 4 In a preferred embodiment of the present invention, the base 23 is configured as a "U" shaped structure, and a height limiting plate 231 and a baffle 232 are inclinedly arranged inside it. The lower end of the height limiting plate 231 has a gap with the upper surface of the conveyor belt 26, and the lower end of the baffle 232 slides in contact with the upper surface of the conveyor belt 26.

[0036] In practical application, the base 23, together with the height limit plate 231 and the baffle 232, plays a limiting and constraining role on the material on the conveyor belt 26, preventing plastic scraps from falling into the machine housing 1 through the gap between the material distribution component 2 and the machine housing 1. Furthermore, the gap between the height limit plate 231 and the upper surface of the conveyor belt 26 further limits the amount of plastic scraps passing through the conveyor belt 26, thereby further improving the material distribution effect.

[0037] Please see Figure 2 In another preferred embodiment of this utility model, a guide plate 13 is fixedly installed on the inner side of the housing 1 above the fan 3. The guide plate 13 is inclined and its lower end extends to the bottom of the base 23. A limiting plate 131 is also fixedly installed above the partition plate 16. The guide plate 13 and the limiting plate 131 are used to guide the plastic scraps.

[0038] In practical application, the guide plate 13 and the limiting plate 131 are located below one side of the machine base 23. When the plastic scraps on the conveyor belt 26 move to the edge and fall, the guide plate 13 and the limiting plate 131 constrain and limit the plastic scraps, so that they fall vertically and pass through the air outlet of the fan 3, ensuring the sorting effect and preventing the material from flying around and affecting the sorting effect.

[0039] Please see Figure 2 In another preferred embodiment of this utility model, two collection boxes 18 are respectively provided on both sides of the partition plate 16. The collection boxes 18 are movably located inside the housing 1 and extend movably to one side of the housing 1 for collecting sorted plastic scraps.

[0040] In practical application, this embodiment facilitates the collection of plastic scraps by using the partition plate 16 as a partition and the collection boxes 18 set on both sides of the partition plate 16. By disassembling the collection boxes 18, the plastic scraps can be easily put into the next recycling process, thus improving the efficiency of process connection.

[0041] Please see Figure 2 and Figure 3 In another preferred embodiment of this utility model, a second partition plate 17 is fixedly installed at the bottom of the housing 1 on one side of the first partition plate 16. A dust collection box 19 is provided on the other side of the second partition plate 17 opposite to the collection box 18. The dust collection box 19 is movably located inside the housing 1 and extends movably to one side of the housing 1. The dust collection box 19 is close to the inner wall of one side of the housing 1 and is used to collect small dust particles and impurities separated from the crushed material sorting.

[0042] Furthermore, an installation groove 191 is fixedly provided on one side of the dust collection box 19 at the position corresponding to the air outlet 15. A filter plate 192 is fixedly installed in the installation groove 191. The filter plate 192 is configured with a loose and porous structure to isolate and filter the dust in the dust collection box 19.

[0043] In practical applications, this embodiment uses the dust collection box 19 to collect existing dust in the material, and the filter plate 192 ensures air permeability while isolating the dust, preventing the dust from being directly discharged into the air. The large amount of dust accumulates in the dust collection box 19, which can also be used for the recycling of microplastics in the dust.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
