Technical Field
[0001] This utility model belongs to the technical field of spiral feeders, specifically a double spiral feeder for high-speed drawing and filling masterbatch production. Background Technology
[0002] Filler masterbatch is a granular premix made by melt blending a high proportion of fillers (such as calcium carbonate, talc, mica, etc.) with carrier resin (such as PE, PP, etc.) and a small amount of additives (such as dispersants and coupling agents). During the production of plastic products, it is added to the base resin in a certain proportion to achieve filler modification.
[0003] In the production process of high-speed drawing filler masterbatch, the feeding process plays a crucial role. Traditional feeders often have difficulty accurately controlling the flow rate when handling highly fluid materials, which can easily lead to material waste or production interruption. Furthermore, traditional feeders are difficult to control the feeding process stably.

[0010] Preferably, the top of the machine body is fixedly connected to an enlarged material loading port; the enlarged material loading port is located at the top opening of the machine body; the larger material loading port can effectively accommodate more filler material, reduce the frequency of frequent feeding, and greatly improve production efficiency.
[0011] Preferably, a filter screen is placed inside the enlarged material loading port; the filter screen is located at the top of the spiral blades; it can effectively intercept impurities in the filling masterbatch, and by filtering impurities, the purity of the material entering the feeder can be guaranteed, thereby improving product quality.
[0012] Preferably, the helical blades are provided with crushing teeth on their sidewalls; the crushing teeth are arranged in a circular array on the sidewalls of the helical blades; this can effectively crush large particles into smaller particles, so as to facilitate more uniform conveying and feeding in the future.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. The double-spiral feeder for high-speed wire drawing filler production described in this utility model, by placing the material inside the machine body, driving the spiral blades of the drive motor to stir the material, and then using a hand handle to drive the closing plate to open and close the discharge port, and then discharging through the conveying pipe to the outlet, can effectively and accurately measure and convey the material, meet the strict requirements of high-speed wire drawing production for material addition accuracy, and ensure the stability of product quality.
