Title:
PRE-IMPREGNATION SIDE FEEDING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/238461
Kind Code:
A1
Abstract:
Provided are a pre-impregnation side feeding device and method. The device comprises: an extrusion machine body provided with a main machine barrel, wherein the main machine barrel is configured to mix, melt, convey and then extrude a material after same is added; and a material guiding device and a side feeding device, wherein the material guiding device is configured to lead the molten material out from the main machine barrel and then convey same into the side feeding device, and the side feeding device is configured to pre-impregnate and mix, in the side feeding device, a material added at a feed port of the side feeding device and the molten material led in from the material guiding device and then input same into the main machine barrel. The present invention can weaken the influence of side feeding screws on a side fed material, facilitates the side feeding of high proportion components of material, such as powder and glass fiber, and reduces the compression and shearing effects of the feeding screws on the material; furthermore, moisture in the side fed material is forced to be discharged through a feed port or an exhaust hole of the side feeding device in advance, the material mixing effect in the subsequent processing process after the side fed material enters a main machine barrel is ensured, and therefore, the side feeding problem is solved, and product quality is improved.
