Description

Technical Field

[0001] This utility model relates to the field of plastic pellet recycling technology, specifically to an environmentally friendly screening device for recycling plastic pellets. Background Technology

[0002] Environmentally friendly plastic pellets are widely used in packaging, building materials and other fields as a key material for resource recycling. Their raw materials cover various recycled plastics and bio-based materials, and their sources are complex and dispersed, resulting in significant differences in particle size and shape. This diversity places higher demands on the screening process.

[0003] However, traditional screening devices mostly use screen structures with fixed spacing, making it difficult to flexibly adjust the screening spacing according to the actual particle size. When faced with environmentally friendly plastic granules with large differences, fixed screens either have too large a spacing, causing fine particles to mix with coarse particles, or too small a spacing, causing coarse particles to clog the screen, leading to screening or material jamming problems. At the same time, manually changing screens with different spacings is not only time-consuming and labor-intensive, but also interrupts the production process and reduces screening efficiency. It is difficult to adapt to the complex characteristics of environmentally friendly plastic granule raw materials, which restricts the improvement of the quality of recycled granules and the large-scale production. Therefore, there is an urgent need for a screening device for recycling environmentally friendly plastic granules to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 The present invention provides an environmentally friendly screening device for recycling plastic granules, including a screening box 1, and further comprising:

[0025] Adjustable screening component 2 is installed on the inner wall of screening box 1 and is used to screen plastic particles;

[0026] Constraint component 3 and adjustable filter component 2 are set inside adjustable filter component 2 to squeeze and constrain the initial filter size to the minimum state;

[0027] Adjustment component 4 is located on the inner wall of the screening box 1 and is used to adjust the initial screening size according to actual needs.

[0028] Guide component 5 is disposed on the inner wall of the screening box 1 and is used to guide the pulling position of constraint component 3;

[0029] The adjustable screening component 2, constraint component 3, and adjustment component 4 work together to make it easy to adjust the spacing of the screening grid according to the size of the particles, thereby adapting to particles of different sizes, avoiding screen clogging and mixing, improving screening accuracy and efficiency, and meeting the grading requirements of diverse recycled plastic particles for environmental protection.

[0030] Furthermore, the adjustable screening component 2 includes a mounting box 201, which is fixedly connected to the inner wall of the screening box 1. The inner wall of the mounting box 201 is provided with multiple screening plates 202 arranged in an alternating pattern. The inner wall of the mounting box 201 is also provided with multiple cross plates 203, which are divided into two groups. The interior of the mounting box 201 is provided with multiple rotating columns 204, the surfaces of which are rotatably connected to the inner walls of the two cross plates 203. A collection box 6 is slidably connected to the inner wall of the screening box 1, the size of which matches the size of the mounting box 201. Through the adjustable screening component 2, the screening plates 202 located on both sides inside the mounting box 201 can move, thereby causing multiple screening plates 202 to move synchronously. This synchronous movement of the multiple screening plates 202 facilitates changing the spacing between the multiple mounting boxes 201. Changing the spacing between the multiple mounting boxes 201 facilitates the screening of plastic particles of different sizes. The collection box 6 facilitates the collection of the screened plastic particles.

[0031] Furthermore, the constraint component 3 includes multiple connecting posts 301, which are disposed on the inner wall of the screening box 1. The surface of the connecting posts 301 is rotatably connected to the inner wall of the screening plate 202. The inner wall of the mounting box 201 is provided with multiple sliding holes 302, and sliding posts 303 are slidably connected to the inner wall of the sliding holes 302. The surface of the connecting posts 301 is rotatably connected to the inner wall of the sliding posts 303. A compression spring 304 is sleeved on the surface of the sliding posts 303. Through the constraint component 3, the extension of the multiple compression springs 304 pushes the sliding posts 303 to move. The movement of the sliding posts 303 facilitates the movement of the screening plate 202 to restore the spacing size of the multiple screening plates 202 to the minimum state, thereby facilitating subsequent adjustment of the screening spacing according to the plastic particle size.

[0032] Furthermore, the adjusting assembly 4 includes a limiting frame 401, which is fixedly connected to the inner wall of the screening box 1. A threaded block 402 is slidably connected to the inner wall of the limiting frame 401, and a threaded post 403 is threadedly connected to the inner wall of the threaded block 402. The threaded post 403 is rotatably connected to the inner wall of the limiting frame 401. Two flexible oil ropes 404 are fixedly connected to both sides of the threaded block 402, and one end of each flexible oil rope 404 is fixedly connected to a sliding hole 302. The guiding assembly 5 includes multiple guide seats 501, which are all fixedly connected to the inner wall of the screening box 1. A rotating wheel 50 is rotatably connected to the inner wall of each guide seat 501. 2. The surface of the flexible oil rope 404 is movably sleeved with the inner wall of the rotating wheel 502. By setting the adjustment component 4, the threaded column 403 rotates and drives the threaded block 402 to move. The movement of the threaded block 402 pulls the sliding column 303 to move through the flexible oil rope 404. The movement of the sliding column 303 pulls multiple screening plates 202 to move synchronously, thereby making it easier to adjust the screening spacing of multiple screening plates 202 to increase and meet more screening needs. By setting the guide component 5, it is easy to guide the movement path of the flexible oil rope 404, thereby making it easy for multiple flexible oil ropes 404 to move smoothly while being reasonably distributed.

[0033] Working principle: During use, the adjustable screening component 2 causes the screening plates 202 located on both sides inside the mounting box 201 to move, thereby driving multiple screening plates 202 to move synchronously. The synchronous movement of multiple screening plates 202 makes it easier to change the spacing size of the multiple mounting boxes 201. The change in the spacing size of the multiple mounting boxes 201 makes it easier to screen plastic particles of different sizes.

[0034] Secondly, by setting the constraint component 3, the sliding column 303 is moved by the extension of multiple compression springs 304. The movement of the sliding column 303 facilitates the movement of the screening plate 202 to restore the spacing size of the multiple screening plates 202 to the minimum state, which facilitates the subsequent adjustment of the screening spacing according to the plastic particle size.

[0035] Furthermore, by setting the adjustment component 4, the rotation of the threaded column 403 drives the threaded block 402 to move. The movement of the threaded block 402 pulls the sliding column 303 to move through the flexible oil rope 404. The movement of the sliding column 303 pulls multiple screening plates 202 to move synchronously, thereby making it easier to increase the screening spacing of the multiple screening plates 202 to meet more screening needs. The guide component 5 facilitates the guidance of the movement path of the flexible oil rope 404, thereby making it easier for the multiple flexible oil ropes 404 to move smoothly while being reasonably distributed.
