Description

Technical Field

[0001] The utility model relates to the technical field of full-automatic filling machines, in particular to a plastic extruder for processing plastic sheets. Background Art

[0002] Plastic sheet refers to the material used to produce disposable plastic cups, plates, bowls, dishes, boxes and other thermoformed products. It is widely used in the packaging of food, vegetables, fruits, beverages, dairy products, industrial parts and other fields. In the processing of plastic sheets, a plastic extruder is needed to extrude the hot melt material, shape it through a model, and then level it and cool it down through rollers. However, the existing plastic extruders have certain inconveniences when used.

[0003] A plastic extruder for processing plastic sheets is disclosed in Chinese utility model patent application number: CN202020034012.7. When in use, the plastic sheet is extruded by the extruder body, and the sheet enters between the lower pressure roller and the upper pressure roller. The telescopic member pushes the lower pressure roller upward to move the sheet close to the upper pressure roller. The upper pressure roller drives the sheet to move under the action of the driving motor. At the same time, the water tank in the cooling mechanism supplies water, and the water in the water tank is pumped into the first cavity and the second cavity through the water inlet pipe and the rotating joint respectively through the first circulation pump, and then discharged from the water outlet pipe on the other side of the first cavity and the second cavity and flows back into the water tank. The lower pressure roller and the upper pressure roller are cooled by circulating water cooling, thereby taking away the heat of the sheet between the lower pressure roller and the upper pressure roller, and the plastic sheet is quickly cooled. The heat exchanger performs heat exchange treatment on the water tank in real time, and the cooling liquid is cooled by the second circulation pump The circulation flows through the water tank and the heat exchanger, and the water in the water tank is cooled in real time to ensure that the water temperature can cool the processed plastic sheet in real time to ensure the cooling effect. At the same time, the cooled sheet is further cooled by air when passing over the fan. The plastic sheet is cooled twice and quickly cooled and shaped to avoid deformation due to residual heat. However, the plastic extruder cannot scatter the material when filling it. The material is prone to accumulation when filling it, and it takes a long time to melt. If the melting temperature is not high enough, it is easy to cause uneven melting. In addition, the plastic extruder cannot purify the odor emitted by the plastic sheet when cooling the molded plastic sheet. The molten plastic sheet will emit a pungent odor, which is easy to cause harm to the workers' health for a long time. For this reason, we propose a plastic extruder for plastic sheet processing.
