Description of the Related Art Heretofore, as a rotary roller of this type, there has been provided a roller main body made of a resin molded product, on which a brush is helically planted, or a blade made of a soft resin is spirally attached. There is. However, the conventional rotary roller has a solid roller body and a large weight, and 3000 rpm.
When rotating at the above high speed, shaking and noise increase, and the addition to the drive system is large. In particular, a brush-type rotating roller has a problem in that lint or the like is entangled with the brush. In the blade type rotary roller, a spiral groove with a T-shaped cross section is formed on the outer peripheral surface of the roller body by a special method of rotating the die during extrusion molding, and the root of the blade is pushed into this spiral groove for assembly. ing.
However, in the method in which the blade is attached to the roller body in this way, the blade is not always fitted to the roller body, and a gap is generated between the two. This has a problem that the blade comes out of the groove due to friction with the floor or the carpet during cleaning.

る。In order to achieve the above object, a method of manufacturing a rotary roller for a suction port of an electric vacuum cleaner according to the present invention is as follows.
A blade having a locking portion at the base is molded from a soft resin material. Then, the head of the blade is fitted into the spiral groove formed on the inner surface of the cavity of the blow molding die, the parison in the softened state is inserted into the cavity, and after the die is clamped, air is injected into the parison. Blow molding. That is, in the present invention, the roller body is molded by the blow molding method with the blade inserted in the mold. At this time, the outer peripheral surface of the parison (roller body) covers the locking part of the blade,
The roller body and the blade are integrated. After cooling, the mold is opened, the molded product is taken out, and the waste bags at both ends of the roller body are cut to obtain a hollow rotating roller having blades spirally arranged on the outer peripheral surface of the roller body.

立て工程も不要となる。In the rotary roller manufactured as described above, since the roller main body is made of a hollow cylindrical body, it is light in weight, has relatively little shaking and noise even when rotated at high speed, and participates in the drive system (motor). The load is also small. Moreover, since it is a blade type, there is almost no entanglement of lint, etc., and the blade is provided integrally with the roller body, that is,
The blade has a locking portion at its root inserted in the outer peripheral portion of the roller body, and therefore there is no fear of the blade coming off. Further, since the roller body adopts blow molding, special extrusion molding equipment such as rotating the die while pushing out the roller body unlike the conventional extrusion molding is unnecessary. Furthermore, since it is insert blow molding, the assembly process of fitting the blade into the groove of the roller body is not necessary.

During rotation, the heads of the blades 5 and 5 hit the surface of the carpet, scraping dust, lint, etc. from the carpet. The rotary roller manufactured as described above has the roller body 1
Since it is a hollow cylinder, the weight is light and the vibration and noise are relatively small even when rotating at high speed, and the drive system (motor)
The load applied to is also small. Moreover, since the blades 5 and 5 are integrally embedded in the outer peripheral portion of the roller body 1, there is no possibility that the blades 5 and 5 will come off. Further, the blades 5 and 5 do not wobble, the effect of scraping out dust and the like is good, and unlike the conventional brush type, there is almost no entanglement of lint or the like.
