Description

Technical Field

[0001] The utility model relates to the technical field of sheet material production equipment, in particular to an auxiliary material unloading mechanism of a sheet material extrusion production line. Background Art

[0002] In the actual process of producing PLA sheets, the raw material pellets fall into the barrel of the sheet extruder after passing through the discharge port. Through the continuous operation of the main screw, the pellets are sent to the rear section for heating and melting, and finally the product is produced. Because the discharge port is close to the barrel, the heating tiles distributed in the barrel will transfer heat to increase the temperature near the discharge port. There was no temperature control. When the pellet temperature rises after the material accumulates at the discharge port, the PLA sheet raw material will melt and agglomerate, which will block the discharge port and hinder the transportation of the pellets, causing the sheet extruder to lose pressure and shut down, affecting the production efficiency of the sheet. The application number is 20172021 The utility model of 9782.7 discloses a feed port of a sheet extrusion device, wherein the feed port is connected and communicated with the barrel of the extrusion device, wherein a main screw of the extrusion device is arranged in the barrel, and comprises: a water jacket having a water inlet and a water outlet, wherein the water jacket is fittedly sleeved on the outer periphery of the barrel at the connection between the feed port and the barrel. The utility model can cool the feed port so that the material can smoothly enter the barrel of the extrusion device, but the utility model cannot accurately control the feed speed and feed amount of the pellets, and the feed speed and feed amount of the pellets that are too fast or too slow will affect the production quality of the PLA sheet.
