Coating spray head with more uniform in spraying and more sufficient in mixing functions

Abstract

The invention relates to the technical field of sensor manufacturing, and discloses a coating spray head with more uniform spraying and more sufficient mixing functions. The coating spray head comprises a shell, a transmission shaft is rotatably connected to the circle center of the shell, a support plate is fixedly connected to the bottom end of the transmission shaft, a rotary drum is fixedly connected to the side surface of the support plate, telescopic rods are fixedly connected to the surface of the rotary drum, push rods are fixedly connected to the interiors of the telescopic rods, metal contacts are fixedly connected to the end parts of the push rods, resistance strips are slidably connected to the side faces of the metal contacts, and stirring rods are fixedly connected to the ends, away from the rotary drum, of the telescopic rods. The telescopic rods stretch out under the action of centrifugal force, so that the resistance of electric heating wires connected into the interior is reduced, the heating power of the electric heating wires is increased, the end parts of the telescopic rods are fixedly connected to the stirring rods so that an internal solution can be heated during stirring work, the adhesion of the coating solution is prevented, and a paint can be conveniently and smoothly sprayed out.

Description

technical field [0001] The invention relates to the technical field of sensor manufacturing, in particular to a paint nozzle with more uniform spraying and more sufficient mixing. Background technique [0002] In the manufacturing process of thick film sensors, it is necessary to spray the slurry of sensitive materials on the substrate to form a film. The current spraying device cannot stir and heat the coating solution during the spraying process, which makes the coating solution easy to condense into blocks and easy to block. If the nozzle hole is closed, it is not conducive to smooth spraying. The spraying angle of the nozzle is fixed, which makes the spraying uneven, and the sprayed solution particles are large, which affects the performance of the sensor. [0003] In order to solve the above problems, the inventor provides a paint nozzle with more uniform spraying and more sufficient mixing. The telescopic rod is stretched under the action of centrifugal force, so that ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a paint nozzle with more uniform spraying and more sufficient mixing, capable of heating the internal solution when stirring, preventing the bonding of the paint solution, and facilitating the smooth spraying of the paint , and can make the sprayed paint more delicate, and the spraying of the paint through the rotating spray of the nozzle makes the spraying of the paint more uniform, which solves the problem that the spraying device cannot stir and heat the paint solution during the spraying process, so that the paint solution is easy to condense into block, it is easy to block the spray hole, which is not conducive to smooth spraying, the spray angle of the spray head is fixed, which makes the spray uneven and the sprayed solution particles are large, which affects the performance of the sensor
