Helical lamp bepowdering device

Abstract

The invention relates to a helical lamp bepowdering device, comprising a rotating spindle, a motor, a turnplate, an annular guide plate, bepowdering toolings and an oven, wherein, the turnplate drives the rotating spindle through the motor to rotate around the rotating spindle; a plurality of toolings are distributed on the turnplate; the annular guide plate is fixed above the turnplate; each bepowdering tooling comprises a rotating motor, a motor seat, a support arm and a tubular billet hand grip; the rotating motor is connected with the motor seat; the front end of the motor seat is hinged with the turnplate; the rear end thereof is connected with the support arm; the upper end of the support arm is connected with the annular guide plate; the tubular billet hand grip is connected with a power transmission shaft of the rotating motor; the oven is positioned at outside the turnplate; the helical lamp of the invention longitudinally swings in a slant angle and rotates axially, thus avoiding thick spots formation at the local part, and improving bepowdering degree of uniformity of products; the thickness of bepowdering layers on the outer ring and the inner ring of the product is ensured to be consistent by controlling the rotating speed and the action of wind and oven temperature, thus increasing luminous flux of the product and improving lumen maintenance of the product.

Description

technical field [0001] The invention relates to a powder coating device for an energy-saving lamp, in particular to a powder coating device for a spiral lamp tube. Background technique [0002] At present, domestic spiral lamp tube powder coating generally adopts: fix the lamp tube vertically on the transmission chain of the linear machine, let the lamp tube pass through different temperature zones in turn, and blow in a certain amount of wind, and wait for the powder slurry to dry. The phosphor powder is attached to the inner wall of the lamp tube. Under the action of gravity, the slurry gathers at the inner bottom of the lumen. Due to the relationship between the lead angle of the lamp tube, the slurry flows out slowly, and thick spots are easily formed on the bottom of the lumen. Therefore, there are following deficiencies in this production technique and equipment: 1. Since the lamp tube is fixed on the chain, redundant powder slurry can only flow out along the spiral u...

AI Technical Summary

Problems solved by technology

Therefore, there are following deficiencies in this production technique and equipment: 1. Since the lamp tube is fixed on the chain, redundant powder slurry can only flow out along the spiral under the action of gravity, and the lead angle of the lamp tube is very small, and the powder slurry It is not easy to flow out, so a thick powder spot is formed at the bottom of the spiral inner cavity of the lamp tube

The existence of thick spots not only affects the appearance of the lamp tube and wastes fluorescent powder, but also prevents the visible light from passing through and affects the luminous efficiency of the lamp tube; 2. It occupies a large area, and the length of the traditional powder coating machine is generally 9-11m. more demanding
