Description

Technical Field

[0001] The utility model relates to the technical field of single-screw extruders, in particular to a feeding device with a crushing mechanism and a single-screw extruder. Background Art

[0002] Single screw extruder is a widely used equipment in plastic processing, rubber production and food industry, usually composed of screw, barrel, heating zone, cooling zone, mold, etc. Through the rotation of the screw, the material is pushed, heated, plasticized, and finally formed into the desired shape or specification through the mold.

[0003] The prior art discloses some utility model patents in the field of single-screw extruder processing technology, among which the utility model patent with publication number CN215661746U discloses a feeding device for a single-screw extruder, which relates to the technical field of single-screw extruder equipment, and includes a feed hopper and a feeding tube. The lower surface of the feed hopper is fixedly connected to the upper surface of the feeding tube, and the outer wall of the lower end of the feeding tube is fixedly connected to a material blocking box, which is communicated with the feeding tube, and a material blocking chute is provided on the material blocking box, and a material blocking plate is movably connected to the material blocking box, and a handle is fixedly connected to the side of the material blocking plate away from the feeding tube. A material blocking plate is arranged in the material blocking box, and the material blocking box is connected with the feeding pipe. When the material needs to be cut off in time according to the production demand, the material blocking plate is pushed into the feeding pipe by pushing the handle. The material blocking plate cooperates with the material blocking groove on the inner wall of the feeding pipe to complete the timely material cutting. A crushing knife is arranged in the feeding hopper to crush large particles and other materials to avoid a large amount of material accumulating inside the pipeline during the feeding process, causing blockage.

[0004] However, the above method still has the following defects in actual use: although the function of timely material cutting off can be achieved through the material blocking slot and the material blocking plate, the material blocking plate needs to be coordinated manually, and the position of the material blocking slot is mostly fixed. The material in the unloading process is easy to accumulate above the material blocking slot, thereby affecting the fluidity of the material and the uniformity of feeding, and reducing the working efficiency of the single-screw extruder.
