Description

Technical Field

[0001] This utility model relates to the technical field of waste plastic recycling and cleaning equipment, and in particular to a waste plastic recycling and cleaning pretreatment device. Background Technology

[0002] Plastics are polymers formed by polymerization of monomers through addition or condensation reactions. "Waste plastics" is a common term that doesn't refer to discarded, old, or useless plastic products. Most plastic products, especially those used in large quantities for single purposes, don't undergo significant changes in their material properties after use. Therefore, they can be recycled and reshaped for reuse. However, waste plastics are not always clean and require pretreatment. This pretreatment involves washing to remove dirt and impurities before crushing and reshaping. Currently used plastic washing and pretreatment devices are relatively simple, often employing motor-controlled drive rods for agitation and washing. The fixed position of the drive rods results in low washing efficiency. Utility Model Content

[0003] The main purpose of this utility model is to provide a waste plastic recycling and pretreatment device that can effectively solve the problems in the background art.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-3 As shown, a waste plastic recycling and pretreatment device includes a cleaning tank 1. A support foot 101 is installed in a ring on the lower surface of the cleaning tank 1. A feed hopper 2 is fixedly connected to the upper surface of the cleaning tank 1 near the other end. A drain pipe 201 is fixedly connected to the middle of the lower surface of the cleaning tank 1. A control valve 202 is provided on the drain pipe 201. A sealing door 3 is provided on the front surface of the cleaning tank 1 near the lower end. A handle 301 is fixedly installed on the front surface of the sealing door 3. A filter plate 4 is fixedly installed inside the cleaning tank 1 near the lower end. A flipping structure 5 is provided inside the cleaning tank 1.

[0020] The flipping structure 5 includes a servo motor 501, a rotating rod 502, a first bearing 503, a first gear 504, a second gear 505, an annular groove 506, a toothed groove 507, a first rod 508, a second rod 509, a rectangular connecting plate 510, a third bearing 511, a second bearing 512, a first stirring rod 513, and a second stirring rod 514; the servo motor 501 is fixedly installed in the middle of the upper surface of the cleaning tank 1, and the rotating part of the servo motor 501 is fixedly connected to... A rotating rod 502 is present, and a rectangular connecting plate 510 is fixedly installed on the lower surface of the rotating rod 502. A first bearing 503 is fixedly installed in the middle of the upper surface inside the cleaning chamber 1, and the rotating rod 502 is mounted on the first bearing 503. A second bearing 512 is fixedly installed near one end of the rectangular connecting plate 510. A third bearing 511 is fixedly installed near the other end of the rectangular connecting plate 510, and a second rod 509 is mounted on the third bearing 511. A [unclear - possibly a component or part] is mounted on the second bearing 512. A first rod 508 has a first gear 504 fixedly mounted on its upper surface; a second rod 509 has a second gear 505 fixedly mounted on its upper surface; an annular groove 506 is formed on the upper surface of the inner side of the cleaning chamber 1, and a toothed groove 507 is formed on the outer surface of the annular groove 506, which meshes with the first gear 504; the toothed groove 507 meshes with the second gear 505; a second stirring rod 514 is mounted on the second rod 509, and a first stirring rod 514 is mounted on the first rod 508. Rod 513 can activate servo motor 501 during the cleaning of waste plastics, causing rotating rod 502 to drive rod 508, stirring rod 513, rod 509, and stirring rod 514 to rotate. At the same time, stirring rod 513 rotates around rod 508, and stirring rod 514 rotates around rod 509, which performs multiple stirring and turning of the waste plastics inside the cleaning tank 1, improving the cleaning efficiency of waste plastics.

[0021] It should be noted that this utility model is a pre-treatment device for cleaning and recycling waste plastics. When it is necessary to clean waste plastics, the servo motor 501 is started, causing the rotating part of the servo motor 501 to drive the rotating rod 502 to rotate on the first bearing 503, which in turn drives the rectangular connecting plate 510 fixedly installed on the lower surface of the rotating rod 502 to rotate. This causes the first rod 508, the first stirring rod 513, the second rod 509, and the second stirring rod 514 to rotate around the rotating rod 502 as the center. The rotation, because gear 504 meshes with tooth groove 507, drives rod 508 to rotate on bearing 512, causing stirring rod 513 to rotate around rod 508. Gear 505 meshes with tooth groove 507, driving rod 509 to rotate on bearing 511, causing stirring rod 514 to rotate around rod 509. This process performs multiple stirring and turning of the waste plastic inside the cleaning tank 1, improving the cleaning efficiency of waste plastic.
