Description

Technical Field

[0001] The utility model relates to the technical field of extruder feeding, in particular to automatic extruder feeding production equipment. Background Art

[0002] An extruder is a common piece of plastics processing equipment. It heats, mixes, and plasticizes raw plastic, then continuously extrudes it through a mold of a specific shape at a specific pressure and speed to form a continuous profile. This equipment is widely used in the production of products such as plastic pipes, sheets, films, and cable wraps.

[0003] During the operation of the extruder, the raw materials used to make profiles (usually plastic granules or powder) enter the extruder body evenly from the feed port. When the raw material supply exceeds the speed that the extruder can effectively handle, it will cause too much raw material to accumulate at the feed port, affecting the speed and uniformity of the material entering the extruder; once the feed port is blocked, the machine needs to be stopped for cleaning, which not only interrupts the normal production process, but also brings additional time costs and labor input. Utility Model Content

[0029] The material storage box 1 includes a cylindrical body, the bottom end of the body is constructed with a conical connecting section, and the material box outlet 6 is arranged at the bottom end of the connecting section; the conical bottom helps the raw materials to flow smoothly to the outlet, and due to the effect of gravity, the conical structure can reduce the possibility of material accumulation in corners or edges, thereby ensuring that the material can flow out more evenly and continuously; the conical design reduces the chance of material hanging on the wall and reduces the risk of blockage caused by material adhesion; when the material storage box 1 needs to be cleaned, the conical bottom makes it easier to remove residual material, thereby improving work efficiency and ensuring the sanitary conditions of the next batch of production.

[0030] As a preferred embodiment of the above embodiment, a stirring structure 10 is provided in the storage box 1, and the stirring structure 10 includes a rotating rod 11 vertically arranged in the storage box 1, a first driving motor 12 for driving the rotating rod 11 to rotate is provided on the storage box 1, and a first stirring paddle 13 and a second stirring paddle 14 are provided on the rotating rod 11 coaxially cascaded from top to bottom, the first stirring paddle 13 is a symmetrical blade, and the second stirring paddle 14 is an asymmetrical blade.
