Kitchen ventilator volute edge folding and rolling device

Abstract

The invention relates to the field of kitchen ventilators, in particular to a kitchen ventilator volute edge folding and rolling device which comprises an upper pressing plate and a lower pressing plate. The upper pressing plate and the lower pressing plate can rotate. The edge of the upper surface of the lower pressing plate and the edge of the lower surface of the upper pressing plate are provided with limiting edges. The overall shape of the limiting edges is consistent with the shape of the outer edges of an upper side plate and a lower side plate of a volute. Groove extruding blocks capable of horizontally moving are arranged on one side of the upper pressing plate and one side of the lower pressing plate and correspond to grooves of volume surrounding plates. Rolling pieces capable of horizontally moving are arranged on the other side of the upper pressing plate and the other side of the lower pressing plate. When the upper pressing plate and the lower pressing plate rotate, therolling pieces roll the edges of the lateral sides of the volute along the upper edge of the lower pressing plate and the lower edge of the upper pressing plate. According to the scheme, the kitchen ventilator volute edge folding and rolling device is specially used for edge folding, rolling and assembling of the upper side plate, the lower side plate and the surrounding plates of the kitchen ventilator volute, and compared with traditional welding, the kitchen ventilator volute edge folding and rolling device is high in assembling efficiency, good in sealing performance and high in surface finish degree.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a device for folding and hemming a volute of a range hood. Background technique [0002] The range hood is an indispensable appliance in the modern kitchen. After years of development, its structural design has tended to be mature. Among them, the volute set in the bellows is generally composed of an upper side plate, a lower side plate, and a flat structure. It is composed of arc-shaped hoardings arranged between the upper side plate and the lower side plate, and if welding, riveting, etc. are used between the three, it is not only inefficient but also high in production cost; There is no special equipment for hemming and hemming for the shape of the volute of the range hood. The existing hemming machine needs to be produced in sections. [0003] Therefore, the present inventor has done further research on this, and has developed a kind of range hood volute hemming and hemming device...
