Description

Technical Field

[0001] This utility model relates to the field of recycled plastic pellet processing technology, specifically a preheating device for recycled plastic pellets from waste agricultural film. Background Technology

[0002] The main function of the recycled plastic pellet preheating device is to improve the preheating efficiency of the plastic pellets, ensuring that the plastic pellets are heated evenly during subsequent processing, thereby improving processing quality and production efficiency.

[0003] Patent application number CN202421347053.6 discloses a preheating and mixing device for plastic granules. By controlling the extension of a telescopic rod, the telescopic rod drives a drive block to descend. Through the action of a screw rod, the drive block can rotate while descending, thereby driving an electric heating plate to descend and rotate simultaneously. This can stir the plastic granules in the preheating tank. At the same time, the electric heating plate drives a scraper to rotate and descend, thereby scraping off the plastic granules adhering to the inner wall of the preheating tank. The device only requires one drive source to control its operation, reducing the failure rate of the device.

[0004] However, when the aforementioned plastic granule material preheating and mixing device preheats plastic granules of uneven size, the smaller plastic granules heat up faster, while the larger plastic granules heat up slower. When the two are mixed for preheating, on the one hand, it will prolong the preheating time, and on the other hand, it may cause the smaller plastic granules to melt prematurely, causing machine congestion and easy machine failure.

[0028] The stirring assembly 4 includes a first drive wheel 405, a second drive wheel 404, and a first drive shaft 402. There are two of each of the first drive wheel 405, the second drive wheel 404, and the first drive shaft 402. The two first drive wheels 405 are fixedly connected to the outer surface of the lower output end of the dual-shaft motor 3. The two second drive wheels 404 are respectively fixed to the outer surface of the two first drive shafts 402. The outer surfaces of the two sets of first drive wheels 405 and second drive wheels 404 are provided with drive belts 401. The outer surfaces of the two first drive shafts 402 are fixedly connected with four stirring rods 403, so that the stirring is more thorough and the preheating is more uniform.

After the recycled plastic granules pass through the screen 102, the larger recycled plastic granules pass through the discharge chute 104 on one side, and then enter the preheating box 201 through the feeding pipe 9, while the smaller recycled plastic granules fall onto the bottom plate 103 and enter the discharge chute 1 located on the other side with vibration. 04. Then, the material enters the preheating box 201 through the feeding pipe 9. Then, the heating device 203 set on the inner wall of the preheating box 201 is turned on. At the same time, the dual-shaft motor 3 starts, driving the two first transmission wheels 405 below to rotate. The two transmission belts 401 set on the outer surface drive the two second transmission wheels 404 to rotate, driving the two first transmission shafts 402 to rotate, driving the stirring rod 403 fixed above to rotate. When the smaller recycled plastic particles are preheated, the discharge port 12 located below the preheating chamber of the smaller recycled plastic particles is opened. When the larger recycled plastic particles are preheated, the discharge port 12 on the other side is opened.
