Spraying machine and method

Abstract

The invention relates to a spraying machine, in particular to a spraying machine which is more uniform in spraying and higher in spraying efficiency. The spraying machine comprises a spraying system, a working platform, a PLC control system and a heating system. The spraying system comprises an angle-adjustable spray head. The spray head is connected to an X-axis sliding platform through a rotating mechanism. The X-axis sliding platform and a Z-axis sliding platform are connected through sliding. The rotating mechanism is connected with a sample tray and drives the sample tray to rotate around the axis. A clamp is arranged on the sample tray and fixed to the sample tray. The clamp is used for fixing a sample to be sprayed. The heating system comprises a heater and a temperature sensor. The heater is mounted on the sample tray and arranged in the curved sample. According to the spraying machine, the spray head can be adjusted to keep being perpendicular to the curved surface, perpendicular spraying to the surface of the curved sample is kept when the spray head is used for spraying, and the spraying uniformity is improved.

Description

technical field [0001] The invention relates to a spraying machine, in particular to a spraying machine with more uniform spraying and higher spraying efficiency. Background technique [0002] Most of the existing spraying methods are for flat products, and the entire spraying process is realized by moving the X, Y, and Z axes. The nozzle is relatively fixed, and there is no need to adjust the fixed position of the nozzle and the axis. When using the existing spraying method to spray the curved surface sample, the problem of uneven spraying will occur. As the nozzle moves along the axis, the nozzle and the curved surface sample will form a certain angle. When the spraying material is incident, it is incident on the curved surface at a certain angle. On the surface of the sample, it is easy to cause the place that needs to be sprayed not to be sprayed, and the thickness of the place to be sprayed is uneven; if the traditional spraying machine for spraying flat products is use...

Problems solved by technology

When using the existing spraying method to spray the curved surface sample, the problem of uneven spraying will occur. As the nozzle moves along the axis, the nozzle and the curved surface sample will form a certain angle. When the spraying material is incident, it is incident on the curved surface at a certain angle. On the surface of the sample, it is easy to cause the place that needs to be sprayed not to be sprayed, and the thickness of the place to be sprayed is uneven; if the traditional spraying machine for spraying flat products is used to spray curved surface samples, it is easy to cause the spraying resin solution to flow in the direction of gravity. The problem of uncontrollable thickness integration
