A screening mechanism for pet recycling

Abstract

This utility model provides a screening mechanism for PET recycling, relating to the field of PET recycling technology. It includes a support frame, with an elastic element fixedly connected to the left end of the support frame. An electric telescopic rod is fixedly connected inside the elastic element, and a mounting plate is fixedly connected to the top of the electric telescopic rod. A first motor is fixedly connected to the outer surface of the mounting plate, and a stirring rod is fixedly connected to the lower output shaft of the first motor through the surface of the mounting plate. This PET recycling screening mechanism uses a second motor to drive a belt to rotate, causing a rotating drum to rotate.

Description

Technical Field

[0001] This utility model relates to a screening mechanism for PET recycling, specifically a screening mechanism for PET recycling, and belongs to the field of PET recycling technology. Background Technology

[0002] With industrial development, the application of plastic products has spread to all areas of industry, agriculture, and daily life. The amount of waste plastic generated worldwide every day is incalculable, putting enormous pressure on the environment. Therefore, the best way to solve the plastic waste problem is to recycle waste plastics. To recycle these plastics, they need to be crushed, washed, screened for impurities, and sorted. Traditional plastic recycling sorting is often done manually, which is labor-intensive, time-consuming, and labor-intensive. Existing automated plastic recycling sorting mechanisms mostly use a single screening hole, which can only perform simple sorting of single shapes.

[0003] Chinese patent publication number "CN 215030860 U" discloses a "screening mechanism" which includes a support, a rotating cylinder rotatably connected to the support about its own axis, and a drive assembly for driving the rotating cylinder to rotate. The rotating cylinder is horizontally arranged, with several through holes on its outer wall and a pusher spiral blade on its inner wall. In this patent, when the rotating cylinder rotates, PET material accumulates inside the cylinder, making it difficult to screen and filter the PET material, causing the raw material to clog inside the rotating cylinder and affecting the screening effect.

[0004] Therefore, a screening mechanism for PET recycling is proposed here. Utility Model Content

[0005] This invention proposes a screening mechanism for PET recycling to solve the problem that existing technologies can only perform simple classification based on a single shape, which is not convenient for recycling.

[0006] This utility model is achieved through the following technical solution: a screening mechanism for PET recycling, including a support frame, an elastic element fixedly connected to the left end of the support frame, an electric telescopic rod fixedly connected inside the elastic element, a mounting plate fixedly connected to the top end of the electric telescopic rod, and a feed pipe fixedly connected to the surface of the mounting plate.

[0007] Furthermore, a first motor is fixedly connected to the outer surface of the mounting plate, and a stirring rod is fixedly connected to the lower output shaft of the first motor through the surface of the mounting plate.

[0008] Furthermore, a rotating shaft is fixedly connected to the upper surface of the stirring rod, and a pushing plate is fixedly connected to the lower surface of the stirring rod.

[0009] Furthermore, a rotating cylinder is rotatably connected inside the bracket, a belt is embedded on the outer wall of the rotating cylinder, a pulley is fitted on the bottom inner diameter of the belt, and the pulley is fixedly connected to the output shaft of the second motor.

[0010] Furthermore, the inner wall of the rotating drum is provided with a spiral blade for rotating and pushing material, and the outer wall of the rotating drum is provided with multiple through holes, with a collection box placed vertically at the bottom of the through holes.

[0011] Furthermore, the right end of the bracket is provided with a discharge port, and a guide plate is fixedly connected to the outside of the discharge port. The guide plate is arc-shaped, and the inner wall of the guide plate forms a guide cavity.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the second motor drives the belt to rotate, which in turn drives the drum to rotate. During the rotation of the drum, materials that do not meet the requirements or other impurities fall out through the through hole. The second motor drives the stirring rod to rotate the shaft and the pusher plate, which avoids the accumulation of materials in the drum and insufficient screening. The elastic element and the electric telescopic rod drive the stirring rod to move back and forth, so that the pusher plate and the spiral blade push the PET material to move. The qualified PET material is pushed out to the guide cavity, which improves the screening efficiency. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0022] Please see Figures 1-4 This utility model provides a screening mechanism for PET recycling, including a support 100. An elastic element 110 is fixedly connected to the left end of the support 100. An electric telescopic rod 120 is fixedly connected inside the elastic element 110. A mounting plate 130 is fixedly connected to the top end of the electric telescopic rod 120. A feed pipe 140 is fixedly connected to the surface of the mounting plate 130. A first motor 150 is fixedly connected to the outer surface of the mounting plate 130. A stirring rod 160 is fixedly connected through the lower output shaft of the first motor 150 through the surface of the mounting plate 130. A rotating shaft 170 is fixedly connected to the upper surface of the stirring rod 160. A pushing plate 180 is fixedly connected to the lower surface of the stirring rod 160. The elastic element 110 and the electric telescopic rod 120 drive the stirring rod 160 to reciprocate back and forth, causing the pushing plate 180 to cooperate with the spiral blade 240 to push the PET material to move.

[0023] In summary, avoid material accumulation and conduct thorough screening.

[0024] Please refer to this carefully. Figures 1-4 The support 100 has a rotating drum 200 rotatably connected inside. A belt 210 is embedded in the outer wall of the drum 200, and a pulley 220 is fitted on the bottom inner diameter of the belt 210. The pulley 220 is fixedly connected to the output shaft of the second motor 230. The inner wall of the drum 200 has a spiral blade 240 for rotating and pushing materials. The outer wall of the drum 200 has multiple through holes 250, and a collection box 260 is vertically placed at the bottom of the through holes 250. The right end of the support 100 has a discharge port 270. A guide plate 280 is fixedly connected to the outside of 270. The guide plate 280 is arc-shaped and its inner wall forms a guide cavity. The second motor 230 drives the belt 210 to rotate, which in turn drives the rotating drum 200 to rotate. During the rotation of the rotating drum 200, materials that do not meet the requirements or other impurities fall out through the through hole 250. The second motor 230 drives the stirring rod 160 to rotate the rotating shaft 170 and the pusher plate 180 to avoid material accumulation in the rotating drum 200 and insufficient screening.

[0025] In summary, promoting the output of qualified materials will improve work efficiency.

[0026] In use, the worker feeds the recycled material into the drum 200 through the feed pipe 140 at the feed end. The second motor 230 drives the belt 210 to rotate, causing the drum 200 to rotate. During the rotation of the drum 200, materials that do not meet the requirements or other impurities fall out through the through hole 250. The second motor 230 drives the stirring rod 160 to rotate the rotating shaft 170 and the pusher plate 180, preventing material accumulation in the drum 200 and insufficient screening. The elastic element 110 and the electric telescopic rod 120 drive the stirring rod 160 to move back and forth, so that the pusher plate 180, together with the spiral blade 240, pushes the PET material to move. The qualified PET material is pushed out into the guide chamber, improving the screening efficiency.
