Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to a spraying device for metal connecting pieces. Background Art

[0002] Spraying is a coating method that uses a spray gun or a disc atomizer to disperse the spray into uniform and fine droplets by pressure or centrifugal force and apply it to the surface of the object. It can be divided into air spray, airless spray, electrostatic spray and various derivative methods of the above basic spray forms, such as high-flow low-pressure atomization spray, thermal spray, automatic spray, multi-group spray, etc.

[0003] However, there are still some defects in the existing spraying device: 1. The existing spraying device uses a pump to drive the spraying liquid in the spraying box to be transported to the atomizing nozzle to spray the workpiece. In this process, when the workpiece is sprayed, the nozzle will be closed, and there will be hanging droplets on the nozzle. If they fall on the workpiece or the table, it will cause pollution to the workpiece and the table;

[0004] 2. In the existing technical solutions, the spray liquid tank is generally connected to the pump body through a pipe at the bottom of the side, and then connected to the atomizing nozzle to realize the delivery of the spray liquid. However, when the installation environment is limited and the pipe fittings cannot be installed to the bottom of the side of the box, the liquid at the bottom of the box cannot be delivered, resulting in limited usage scenarios.

[0011] By adopting the above technical solution, when in use, the accumulated liquid can be discharged through the inclination of the bottom of the collection frame and the drainage pipe, thereby preventing excessive liquid from overflowing from the front end of the collection frame.

[0012] As a further solution of the utility model: the spray liquid tank comprises a liquid filling port, a liquid filling port is installed on one side of the top of the spray liquid tank, and a liquid level sensor is installed on the inner top of the spray liquid tank.

[0013] By adopting the above technical solution, when in use, spray liquid can be added to the spray liquid tank through the liquid adding port, and the liquid level sensor monitors the liquid level in the spray liquid tank.

[0015] By adopting the above technical solution, when in use, the liquid in the spray liquid box is lifted by raising the supporting plate, and the supporting plate can also scrape the inner wall of the spray liquid box to avoid the spray liquid from solidifying and sticking to the wall.

[0016] As a further solution of the utility model: a vertical electric push rod is installed in the machine platform, and the output shaft of the electric push rod passes through the bottom of the spray liquid box and is connected to the support plate.

[0017] By adopting the above technical solution, when in use, the support plate can be driven to rise and fall by the electric push rod.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the spraying device for metal connectors,

[0019] A collection frame, an inclined guide plate, a nut and a screw rod are provided, and the screw rod is used to drive the nut to move forward and backward, so that the collection frame and the inclined guide plate as a whole can be moved to a position aligned with the nozzle after spraying is completed, so as to collect the liquid that may drip from the nozzle on the top and side, and avoid contamination of the workpiece or the table;

[0020] In addition, the spraying device for metal connectors is also provided with a spray liquid tank, a support plate and an electric push rod. The support plate is driven to rise and fall by the electric push rod, thereby driving the bottom of the spray liquid tank to rise. Even if the installation environment is limited and the connection point of the infusion tube is higher, the spray liquid in the spray liquid tank can still be fully discharged, and the support plate fits tightly with the inner wall of the spray liquid tank. When the support plate is raised, it can also prevent the spray liquid from solidifying on the inner wall of the spray liquid tank. BRIEF DESCRIPTION OF THE DRAWINGS
