Description

An intermittent quantitative feeding device for plastic granule processing

Technical Field

The invention belongs to the technical field of plastic processing, and in particular relates to an intermittent quantitative feeding device for plastic particle processing.

Background Art

Plastic particles refer to granular plastics, which are generally divided into more than 200 types and subdivided into thousands of types. Common plastic particles include general-purpose plastics, engineering plastics and special plastics. Plastic particle melting is the basis and key step in plastic processing. Plastic particles need to be melted before being processed into various plastic products to facilitate molding by extrusion, injection molding, blow molding, compression molding and other methods.

In actual use, when melting plastic pellets, most of the time, manual loading is performed. Manual loading cannot control the number of plastic pellets at each loading, resulting in less or more material in the melting process, which in turn affects the product quality during plastic extrusion.

When in use, plastic particles are added into the feed box 206, and the power output motor 202 is started. The power output motor 202 drives the through slot 204 to rotate, and the through slot 204 drives the conveying auger 301 to rotate through the driven wheel 302. As the conveying auger 301 rotates, the conveying auger 301 drives the driving pulley 306 to rotate through the driving bevel gear 303 and the driven bevel gear 304. The driving pulley 306 drives the driven pulley 307 to rotate synchronously through the transmission belt 308. As the driven pulley 307 rotates, the rotating rod 309 rotates synchronously with the driven pulley 307. The movable rod 1 312 set on the rotating rod 309 rotates outwardly under the action of centrifugal force as the rotating rod 309 rotates. When the movable rod 1 312 rotates outward, the movable rod 1 312 drives the lifting block 31 through the movable rod 2 315. 0 for height adjustment, at the same time, the driving motor 422 is started, the driving motor 422 drives the conical roller 423 to rotate, the rotation of the conical roller 423 drives the speed adjusting wheel 408 to rotate, the speed adjusting wheel 408 drives the driving gear 411 to rotate through the rotating shaft 410, the driving gear 411 drives the passive gear 415 to rotate through the intermediate gear 413, the passive gear 415 drives the turntable 417 to rotate through the connecting shaft 416, with the rotation of the turntable 417, the turntable 417 drives the movable baffle 420 to move back and forth through the connecting rod 1 418 and the connecting rod 2 419, so that the material inside the feed box 206 enters the processing shell 103, the heating tube 5 is started, the heating tube 5 heats the processing shell 103, so that the plastic particles inside the processing shell 103 are melted, and the molten plastic is transported under the action of the conveying auger 301.

When there is more material in the processing shell 103, the resistance encountered by the conveying auger 301 when conveying the material increases, and the rotation speed of the conveying auger 301 decreases. After the rotation speed of the conveying auger 301 decreases, the centrifugal force on the movable rod 312 decreases, and the movable rod 312 contracts inwardly under the gravity of the counterweight block 313. As the movable rod 312 contracts inwardly, the lifting block 310 moves upward, and the lifting block 310 drives the rotating rod 402 to move toward the center of the docking shaft 404 through the transmission rod 401. The lifting bracket 405 slides downward along the limiting slide groove 407 driven by the rotating rod 402, thereby causing the speed adjusting wheel 408 to move downward along the rotating shaft 410. As the speed adjusting wheel 408 moves downward, the speed adjusting wheel 408 gradually contacts the larger diameter portion of the conical roller 423, thereby increasing the rotation speed of the speed adjusting wheel 408, thereby increasing the rotation speed of the turntable 417, and accelerating the moving speed of the movable baffle 420, thereby reducing the amount of material entering the processing shell 103.

After the amount of material entering the processing shell 103 decreases, the rotation speed of the conveying auger 301 gradually increases. As the rotation speed of the conveying auger 301 gradually increases, the movable rod 312 gradually expands outward, and the speed adjusting wheel 408 moves upward under the drive of the lifting bracket 405, so that the rotation speed of the turntable 417 is reduced, and the moving speed of the movable baffle 420 is slowed down, so that more material can enter the interior of the processing shell 103. After several times, the rotation speed of the conveying auger 301 tends to be stable, and then the number of plastic particles entering the processing shell 103 each time remains stable, and the heated molten plastic is extruded through the discharge mold 104. The above is the overall workflow of the present invention. Just repeat this step next time you use it. The actual operation process is very simple and easy.

It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
