Hardware paint spraying machine with polishing and rust removing functions

Abstract

The invention discloses a hardware paint spraying machine with polishing and rust removing functions. The hardware paint spraying machine structurally comprises a housing, a rust removing device, a distribution box, a working cavity, a conveying belt and a fixed base, wherein the housing is mounted on the fixed base, the fixed base is fixedly connected with the housing, and the rust removing device is arranged in the working cavity. The hardware paint spraying machine has the beneficial effects that a polishing layer is arranged in an arc-shaped inwards-sunken mode, so that the polishing layeris matched with the joints between the surfaces of a hardware workpiece in the rotating working process, and the joints between the surfaces of the workpiece are always in an obtuse angle state; in the process that a grinding wheel and a fixed grinding block rotate along with a grinding head, the friction force between the hardware workpiece and the grinding head is increased through clamping lines on the fixed grinding block; and through annular protrusions on protrusions and trapezoidal protrusions rotating along with a hub, the annular protrusions and the trapezoidal protrusions rapidly collide and rub with the surface of the hardware workpiece to remove rust on the surface of the hardware workpiece, and rust removing of the hardware workpiece is achieved on the premise that the safetyof using the hardware workpiece by operators in the later period is guaranteed.

Description

technical field [0001] The invention relates to the field of hardware painting, in particular to a metal painting machine with the function of grinding and derusting. Background technique [0002] The hardware workpiece will be polished and polished before painting to remove the metal rust on the surface, so that the hardware workpiece can be protected after the hardware workpiece is painted, and the rust layer in the paint layer will not continue to corrode the hardware workpiece. The current The hardware painting device with the function of grinding and derusting has the following defects: [0003] The existing metal spraying device with the function of grinding and derusting closes the grinding surface to the surface of the metal workpiece to be derusted. In order to avoid being cut during the use of the metal workpiece, the surface of the workpiece is usually placed The connection is polished to an obtuse angle, but in the process of derusting the metal workpiece, the c...
