Abstract

A spray coating apparatus includes a tank, spray gun, pump, and base, the pump having an inlet and outlet, the tank detachably mounted on the base, the pump disposed in the base; a switching valve at the bottom of the tank, a communication structure communicating the switching valve with the inlet on the base; the tank, when being mounted on the base, actuates the switching valve to switch from closed to open, and when detached from the base, actuates the switching valve to switch from open to closed. If residual coating material remains in the tank after coating, the tank may be removed to empty the residual material or transfer it back to an external container. In addition, due to detachable setting of the tank, it is only needed to replace the worn tank alone, so that replacement cost may be reduced.

Abstract

A temperature anomaly handling method includes: a step when a temperature rise reaches a certain temperature within a first time interval, the control module determines occurrence of temperature anomaly and performs a step in which the control module starts countdown, and in a case that a temperature rise of the temperature sensing element reaches a second temperature within a second time interval, the control module determines that temperature anomaly lasts based on a temperature signal fed back from the temperature sensing element, and performs a step in which the control module executes a protection program. By determining whether temperature anomaly really occurs to the equipment based on twice dynamic temperature rise signals of the temperature sensing element, determination accuracy may be significantly enhanced; without actual occurrence of temperature anomaly, the heating element performs heating normally, which may guarantee operating effect of the equipment.

Abstract

An electrostatic generation device for an atomizer solves the problem of poor spraying effect of the atomizer. When the electrostatic generation device is used, the fan blows air through the water outlet pipe, and part of the airflow passes through the pressure tube into the water tank, continuously increasing the air pressure inside the water tank. The greater pressure forces the liquid inside the water tank into the inlet pipe and along the inlet pipe into the guide tube, spraying out from the guide tube in the direction away from the fan through the water outlet pipe. The liquid is electrified by the charged metal valve core, and the electrostatically charged liquid is sprayed out through the air outlet, forming electrostatically charged atomized particles. The spray can easily adhere to the object being sprayed, resulting in a higher spraying efficiency.

Abstract

Disclosed in the present invention is a screw shearing machine, which comprises a shearing assembly and a driving assembly. The shearing assembly comprises a shearing base, a fixed cutter fixed to the shearing base, a shearing arm hinged to the shearing base, a moving cutter fixed to the shearing arm, a reset spring connected to the shearing arm, a cam rotatably connected to the shearing base, and a roller rotatably connected to the shearing arm. The driving assembly comprises a motor and a speed reducer for driving the cam to rotate. By means of action of the surface of the cam and the outer circular surface of the roller, the shearing arm is driven to swing so as to drive the moving cutter and the fixed cutter to cooperatively shear a screw. The surface of the cam and the outer circular surface of the roller are matching conical surfaces having an angle of X°, so that when rotating, the cam applies an axial component of force to the roller. Under the action of the force, the shearing arm moves in the axial direction of a bolt, so that the moving cutter and the fixed cutter are always pressed on a shearing end surface. Therefore, when the moving cutter and the fixed cutter cooperatively complete screw shearing, said two cutters basically have no gap therebetween, thus avoiding burrs being formed on a sheared screw because of a gap between a moving cutter and a fixed cutter.
