Description

Technical Field

[0001] The utility model relates to the technical field of plastic parts recycling, in particular to a plastic parts recycling device for a construction site. Background Art

[0002] Plastic products are widely used in industry, agriculture, construction and daily necessities. Plastic is a non-renewable resource. Its production consumes a lot of limited resources such as oil. By recycling and reusing waste plastics, we can reduce dependence on raw materials, extend the service life of resources and protect the natural environment. A large number of plastic accessories are used on construction sites, some of which are disposable and need to be recycled after use. When crushing and recycling plastic accessories, the plastic is only crushed once. There may be plastic that does not come into contact with the crushing blades when passing through the crushing blades, and there are more uncrushed plastics, which makes the crushing effect of the plastic poor, affecting the recycling of plastic waste.

[0024] Please refer to Figure 1-7 A plastic parts recycling device for construction sites, comprising a box body 1, a crushing roller 2 arranged in the box body 1, a guide plate 3 arranged below the crushing roller 2, a filter plate 4 arranged below the guide plate 3, and an extrusion mechanism 5 arranged below the filter plate 4. A feed port 11 is arranged at the top of the box body 1, and a discharge port 12 is arranged at the lower part of one side of the box body 1. Plastic parts are put into the box body 1 from the feed port 11, fall onto the guide plate 3 after being crushed by the crushing roller 2, and then slide onto the filter plate 4 through the guide plate 3. After being crushed, small-sized plastics directly fall into the bottom of the box body 1 when passing through the filter plate 4, and large-sized plastics slide into the extrusion mechanism 5 after being crushed. The extrusion mechanism 5 squeezes and crushes the large-sized plastics, and then falls into the bottom of the box body 1, and then is discharged from the discharge port 12.

[0025] In order to crush the plastic with a larger size after the initial crushing, the extrusion mechanism 5 includes a rotating motor 51, an eccentric wheel 52, a roller 53, a connecting block 54, a driving rod 55, an extrusion block 56 and an extrusion box 57. The box body 1 is fixedly provided with a mounting frame 13, the rotating motor 51 is fixedly provided on the mounting frame 13, the eccentric wheel 52 is eccentrically provided at the output end of the rotating motor 51, and a slide groove 521 is provided on the side surface of the eccentric wheel 52 away from the rotating motor 51. The slide groove 521 is an annular concave The roller 53 is slidably arranged in the slide groove 521, the connecting block 54 is triangular, one corner of the connecting block 54 is hinged to the mounting frame 13, the second corner of the connecting block 54 is hinged to the roller 53, the third corner of the connecting block 54 is hinged to the driving rod 55, the other end of the driving rod 55 is hinged to one side of the extrusion block 56, a sliding key is arranged at the bottom end of the extrusion block 56, and a slideway is arranged at the top of the bottom of the extrusion box 57, so that the extrusion block 56 can slide at the bottom of the extrusion box 57.

[0026] The rotating motor 51 drives the eccentric wheel 52 to rotate. When the eccentric wheel 52 rotates eccentrically, the slide slot 521 rotates eccentrically. Under the limiting action of the slide slot 521, the roller 53 moves up and down. The up and down movement of the roller 53 drives one side of the connecting block 54 to shake up and down. The connecting block 54 drives the driving rod 55 to push and pull the extrusion block 56 back and forth to slide at the bottom of the extrusion box 57, squeezing the plastic in the extrusion box 57, thereby achieving a secondary crushing effect.

[0027] The top of the extrusion box 57 is provided with a feed port 571, so that the plastic fragments fall into the extrusion box 57 after passing through the filter plate 4, and the bottom of the extrusion box 57 is provided with a filter hole so that the plastic with a small size after extrusion can fall below.

[0028] The guide plate 3 is tiltedly arranged on the inner side of the box body 1 so that the crushed plastic can slide to one side along the guide plate 3. The filter plate 4 is tiltedly arranged on the inner side of the box body 1 and is arranged opposite to the guide plate 3. A filter groove is arranged on the filter plate 4.

[0029] Since some plastic accessories may contain metal parts such as screws, in order to screen out iron products from plastic fragments, a magnetic separation mechanism 6 is provided below the extrusion mechanism 5, and the magnetic separation mechanism 6 includes a driving wheel 61, a driven wheel 62, a synchronous belt 63, a gear ring 64, a rotating drum 65, a magnetic ring 66, a fixed drum 67 and a material guide 68. In order to drive the gear ring 64 to rotate, a spur gear 621 is provided on the outer surface of the driven wheel 62, the fixed drum 67 is provided below the extrusion mechanism 5, and the magnetic ring 66 is arranged around the outer surface of the fixed drum 67. In order to facilitate the falling and collection of magnetic fragments, an opening is provided on the side of the magnetic ring 66 away from the filter plate 4, that is, the magnetic ring 66 is a C-shaped ring with an opening. The rotating drum 65 is rotatably arranged on the outer surface of the magnetic ring 66, and the gear ring 64 is fixedly arranged around one end of the rotating drum 65 and meshes with the spur gear 621.

[0030] In order to drive the driven wheel 62 to rotate, the driving wheel 61 is arranged at the output end of the rotating motor 51, and the driving wheel 61 and the driven wheel 62 are both rotatably arranged on the inner wall of the box body 1, and the synchronous belt 63 is sleeved on the outer surface of the driving wheel 61 and the driven wheel 62, and is staggered with the position of the spur gear 621, so as not to affect the meshing of the spur gear 621 and the gear ring 64. When the rotating motor 51 is working, the driving wheel 61 drives the driven wheel 62 to rotate, drives the spur gear 621 and the gear ring 64 to rotate, and drives the rotation of the drum 65 at the same time.

[0031] In order to magnetically separate the plastic fragments, the material guide portion 68 is arranged below the rotating drum 65. The material guide portion 68 surrounds the lower half of the rotating drum 65. The plastic fragments slide from one side of the material guide portion 68 to the bottom of the rotating drum 65, and are discharged from the other side of the material guide portion 68 after magnetic separation.

[0032] In order to facilitate classified recycling, a discharge port 12 is set on one side of the box body 1, and the discharge port 12 has two upper and lower ones. A guide plate 69 is set on one side of the rotating drum 65 to guide the discharge of magnetic waste. One side of the guide plate 69 corresponds to the opening of the magnetic ring 66, and the other side corresponds to the upper discharge port 12.

[0033] During operation, plastic parts are put into the feeding port 11, crushed by the crushing roller 2, and then slide to the filter plate 4 through the guide plate 3. Small plastic pieces fall directly to the feeding side of the guide part 68, and larger plastic pieces fall into the guide part 68 below after being crushed again by the extrusion mechanism 5, and slide to the bottom of the guide part 68 together with other plastic pieces, and surround the bottom of the rotating drum 65. The rotating drum 65 rotates counterclockwise above the guide part 68. Due to the effect of the magnetic ring 66, the magnetic waste will be adsorbed on the outer surface of the rotating drum 65 and rotate together. When the magnetic waste rotates to the opening of the magnetic ring 66, it will separate from the rotating drum 65, fall to the guide plate 69 on the side, and slide out from the upper discharge port 12; when the feeding side of the guide part 68 is continuously fed and the bottom is full, the plastic after magnetic separation is discharged from the other side of the guide part 68, and then slides out from the lower discharge port 12, completing the classified recycling.
