Abstract

The invention provides a nozzle for a powder spraying device and the powder spraying device. The nozzle comprises an outer sleeve, a centering assembly and an inner core, wherein the outer sleeve comprises a first sleeve body and a second sleeve body, the first sleeve body is provided with a first through hole, and the second sleeve body is provided with a second through hole; the centering assembly comprises a positioning cylinder and a positioning core, a channel is formed between the positioning cylinder and the positioning core, the upper end of the positioning cylinder is coaxially connected with the first sleeve body, the lower end of the positioning cylinder is coaxially connected with the second sleeve body, and the channel communicates with the first through hole and the second through hole; and the inner core is arranged in the second through hole, the upper end of the inner core is coaxially connected with the lower end of the positioning core, a cavity communicating with the channel is formed between the inner core and the second sleeve body, and a spraying port is formed between the bottom edge of the second sleeve body and the bottom edge of the inner core. Accordingto the nozzle, by arranging the centering assembly, coaxial assembling of the outer sleeve and the inner core can be achieved, it is guaranteed that the spraying port is a circular ring with a uniformring width, assembling operation is simple, convenient and fast, it is unnecessary to manufacture a tool separately for assembling, and the workload and difficulty of processing and assembling are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of spraying, in particular to a nozzle for a powder spraying device and a powder spraying device. Background technique [0002] Existing nozzles for powder spraying devices are composed of an outer jacket and an inner core fixed in the outer jacket. The outer jacket and the inner core are of a rotary structure, and a cavity is formed between the outer jacket and the inner core. The outer jacket and the inner core are vertically spaced The two staggered pin shafts are fixedly connected, and the powder with static electricity enters from the upper inlet of the nozzle, and is sprayed out from the annular gap of the nozzle after passing through the cavity. [0003] Existing nozzles for powder coating installations have the following disadvantages: [0004] 1. In order to ensure that the jacket and inner core of the nozzle used in the powder spraying device form two concentric circles at the outlet of the nozzle...
