Embodiment 1

[0055] This embodiment provides a precision nozzle with controllable ejection volume and ejection frequency, such as Figure 1 to Figure 6 As shown, it includes a casing 1, and also includes a luffing mechanism 2, a frequency conversion rotating mechanism 3, a material suction and spray mechanism 4 and an atomization cover 5;

[0056] The luffing mechanism 2 includes a feed seat 201 installed on the inner top surface of the casing 1. A lead screw 203 driven by a feed motor 202 is installed on the feed seat 201. A feed slider 204 is installed on the lead screw 203. The feed slider 204 contacts the feed seat 201 to limit the position, so that the feed slider 204 moves laterally under the drive of the lead screw 203; the bottom of the feed slider 204 is fixedly equipped with a cam mounting seat 205, and A camshaft 206 arranged laterally in a rotatable installation is provided with a cam 207 on the camshaft 206;

[0057] The frequency conversion rotation mechanism 3 is fixedly in...

Abstract

The invention provides a precision sprayer capable of controlling the spraying amount and spraying frequency. Paint sprayed by the precision sprayer is spraying points; the spraying frequency of the precision sprayer is controllable, so that the number of spraying points in unit time is controllable; the spraying range of the precision sprayer is controllable, so that the paint amount of each spraying point is controllable; and the precision sprayer adopts a point spraying mode and controls the spraying frequency and spraying range, thereby realizing on-demand feeding. The spraying frequency and spraying range of the sprayer are controllable, the on-demand feeding mode is adopted, the spraying frequency and spraying range can be automatically adjusted according to the moving speed and therequirements of sprayed workpieces, the spraying thickness can be effectively controlled, and the precision of the sprayer is improved.

Description

technical field [0001] The invention belongs to the field of automatic spraying and relates to a spray head, in particular to a precision spray head with controllable spray volume and spray frequency. Background technique [0002] At present, the nozzles used in the automatic spraying of macromolecular particles such as paint on the market are basically automatic spray guns. Equipped with a set of high-tension springs, when the supply of compressed air stops, the springs push the piston and the spray needle forward. At this time, the spray needle and the nozzle are closely matched with high precision to block the passage of the liquid. On the contrary, when the compressed air When the air starts to supply, the pressure of the compressed air pushes the piston away, creating a gap between the spray needle and the nozzle for the liquid to spray out, and the sprayed liquid immediately contacts with the atomizing air to produce an atomizing effect. [0003] It has the following ...
