Description

Technical Field

[0001] The utility model belongs to the technical field, in particular to a stretching and shaping roller of a plastic extrusion flat film drawing machine unit. Background Art

[0002] Stretching and shaping refers to the process of pulling and stretching the filamentary wire produced from the extrusion flat film drawing unit to shape it. In the process of stretching and shaping, a stretching and shaping roller is needed. The stretching roller is connected to the drive shaft. Under the power support of the drive shaft, it rotates around the center of the drive shaft, and then the plastic wire hung or wrapped on it is stretched and shaped.

[0003] A Chinese patent application (or patent) with announcement number CN2860816Y discloses a stretching and shaping roller for a plastic extrusion flat film wire drawing unit, which comprises a transmission shaft and a roller body. A support arm is mounted on the transmission shaft, and the front end of the support arm is fixed to a wall panel. Both ends of the support arm are fixedly connected to the transmission shaft through bearings. An inner expansion ring and an outer expansion ring are mounted on the rear end of the transmission shaft. One end of the roller body is fixedly connected to the transmission shaft through an outer expansion ring and an inner expansion ring, and the other end is fixedly connected to the support arm through a bearing. The stretching and shaping roller for the plastic extrusion flat film wire drawing unit of the utility model has a simple structure and can effectively suppress the jumping degree of the roller body. Therefore, the linear speed of the stretching and shaping roller for the plastic extrusion flat film wire drawing unit can be increased, thereby increasing the speed of the entire production line, increasing the output, and improving the quality of the product wire.

[0004] The above-mentioned stretching and shaping roller of a plastic extrusion flat film drawing machine has an inner expansion ring and an outer expansion ring on the inner and outer sides of one end of the roller body, and the roller body is connected to the transmission shaft on the unit through the inner expansion ring and the outer expansion ring. However, the inner expansion ring and the outer expansion ring are elastic, and being in a stretched state for a long time will cause a great burden on themselves and are also prone to breakage or even unusable. In addition, the outer wall of the roller body is smooth and is used to stretch and shape the extruded plastic filament. When the plastic filament drawn out from the extrusion flat film drawing machine is drawn and shaped, it is in contact with the external environment for a long time, and its own temperature brought by the extrusion flat film drawing machine will also drop sharply. When its temperature is the same as or lower than room temperature, it is difficult for the plastic filament to be stretched and shaped. To this end, we provide a stretching and shaping roller of a plastic extrusion flat film drawing machine to solve the above-mentioned problems. Utility Model Content
