Description

Technical Field

[0001] The utility model particularly relates to a pelletizer which is easy to clean. Background Art

[0002] A pelletizer is a device used to cut materials such as plastics and rubber into pellets. It usually consists of a feeding device, a cutting device, a transmission device and a control system, and can adjust the cutting speed and particle size as needed. Pelletizers are widely used in the plastic recycling industry. By cutting waste plastics into pellets, it is convenient for subsequent processing and reuse, which helps reduce environmental pollution and waste of resources.

[0003] For example, the Chinese utility model patent with the publication number "CN206883950U" discloses an underwater pelletizer system, which is specially used for underwater production. In addition to the feeding device, cutting device, transmission device and control system, it is also equipped with a casting head, a dryer, an overflow water tank, a starting plate, a guide plate, a cutting plate and other parts, and a plurality of spray water outlets are also provided on the casting lead-out part. The underwater pelletizer system has good advantages in the field of underwater pelletizing technology, but in real life, pelletizing in a "waterless" environment is the most widely used, that is, a conventional working environment. However, the underwater pelletizer has the following defects in a conventional working environment:

[0004] First, the pelletizer needs to be cleaned after a long period of pelletizing. If the water outlet system in the pelletizer is directly used for cleaning, blockage is very likely to occur. This is mainly because the waste particles will accumulate under the drive of the water flow and are very likely to accumulate at the bottom of the feeding device and the cutting knife, which directly leads to damage to the pelletizer. In serious cases, the entire machine needs to be disassembled for repair.

[0005] Secondly, after repeated use of water for cleaning, the various parts are very easy to rust and corrode, and parts need to be replaced frequently, so the equipment maintenance is relatively frequent, which greatly affects the production efficiency in actual production.

[0006] Third, the pelletizer mentioned above has an extremely complex structure and contains multiple precision components, such as a start plate, a guide plate and a cut-off plate. These components need to be precisely aligned, and the surface finish and straightness requirements are extremely high. Any deviation may affect the cutting efficiency and product quality. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide a pelletizer which is easy to clean in view of the deficiencies of the above-mentioned prior art.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pelletizer that is easy to clean, comprising a frame, a cutting frame installed on the frame, a cutting chamber being provided in the cutting frame, a feeding mechanism communicating with the cutting chamber being linked above the cutting frame, a cutting knife mechanism being distributed in the cutting chamber, the feeding mechanism comprising a discharging barrel, a feeding channel running through the discharging barrel, one end of the feeding channel being open, and the other end being communicated with the cutting chamber, characterized in that a cleaning area is provided at the side wall of the discharging barrel and located below and close to the cutting chamber, the feeding mechanism also comprises a feeding cover corresponding to the cleaning area, a first sub-page is screwed to one side of the feeding cover, the discharging barrel is screwed to a first main page at a position corresponding to the first sub-page, the first sub-page is rotatably connected to the first main page by a first hinge shaft, and the other side of the feeding cover is detachably connected to the discharging barrel; when the feeding cover is turned around the hinge between itself and the discharging barrel and toward the cleaning area to be connected with the discharging barrel, the feeding cover can block the cleaning area.

[0009] By adopting the above technical solution, a cleaning area is set under the cutting chamber near the side wall of the discharge barrel of the discharge mechanism, and a corresponding discharge cover is provided, so that the pelletizer is easier to clean and maintain, and the possibility of waste particles accumulating at the bottom of the discharge device and the cutter is reduced, thereby reducing the risk of blockage.

[0013] By adopting the above technical solution, by setting the guide plate on the inner wall of the discharge barrel, the precise guidance and positioning of the material is achieved. The relative arrangement of the left guide plate and the right guide plate allows the material to pass smoothly in the discharge barrel, avoiding the blockage and accumulation of the material during the transportation process. At the same time, the arrangement of the lower guide plate ensures that the material can accurately fall into the cutting chamber and fall to the cutter mechanism, ensuring the smooth progress of the cutting process.
