Double-head spray gun

Abstract

The invention discloses a double-head spray gun. The double-head spray gun comprises a gun body, two gun heads, a motor and four wire feeding mechanisms; the gun heads are arranged at one end of the gun body, the motor is arranged on the gun body, the four wire feeding mechanisms are connected with output shafts of the motor correspondingly, every two wire feeding mechanisms correspond to one gunhead, and air feeding pipelines are arranged in the gun body and correspond to the gun heads. Through the arrangement of the two gun heads and the four wire feeding mechanisms, four-way zinc wire metal spraying is achieved, so that the diameters of zinc wires used by the two gun heads can be reduced under the same metal spraying efficiency, the heat of a fuse wire can be correspondingly reduced, metal spraying can be conducted under the condition of a low gun distance, in this way, the scattering angle of the double-head spray gun is greatly reduced; the utilization rate is higher than that ofa single-head gun; meanwhile, due to the fact that the diameter of the zinc wires is reduced and the gun distance is reduced, therefore, compressed air needed in the working process is greatly reduced, generated dust is synchronously reduced, and therefore the effects of energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention belongs to the field of capacitor processing equipment, in particular to a double-head spray gun. Background technique [0002] The existing gold-spraying gun head of the capacitor adopts one gun head, that is, single-point spraying. The single-head gun uses two zinc wires to spray gold. The diameter of the required zinc wire is relatively large, and the heat of the fuse is relatively high. The larger the distance, the larger the scattering angle and the lower the utilization rate of the material; at the same time, due to the larger diameter of the zinc wire, the heat at the fuse point is larger, the required compressed air is also more, and the generated dust is more. cause environmental pollution. [0003] Most of the copper tubes used in the current single-head guns are made of two straight tubes aligned straight, or a single straight tube bent.

[0002] The existing gold-spraying gun head of the capacitor adopts one gun head, that is, single-point spraying. The single-head gun uses two zinc wires to spray gold. The diameter of the required zinc wire is relatively large, and the heat of the fuse is relatively high. The larger the distance, the larger the scattering angle and the lower the utilization rate of the material; at the same time, due to the larger diameter of the zinc wire, the heat at the fuse point is larger, the required compressed air is also more, and the generated dust is more. cause environmental pollution

[0003] Most of the copper tubes used in the current single-head guns are made of two straight tubes aligned straight, or a single straight tube bent. The butt joint angle will produce dead angle or deformation due to bending, which has a great influence on the smoothness of wire feeding. obstruction, easy to block the wire

At the same time, the overall weight of the existing spray gun is relatively large, which has a great influence on the operation stability
