Description

A flap powder cleaning device for a powder spraying room

technical field

The utility model relates to a turning plate powder cleaning device used in a powder spraying chamber.

Background technique

In the existing electrostatic spraying booth, during the spraying process, most of the powder is adsorbed on the surface of the workpiece after being charged, and some powder falls to the bottom of the spraying booth due to gravity. If the excess powder cannot be recovered efficiently, then it will increase the cost of production. For this reason, the existing powder spraying room is generally equipped with a powder recovery device, but in the existing powder recovery device, the powder on the flap generally slides to the bottom of the powder spraying room by gravity, and this design cannot guarantee The powder on the flap can be completely cleaned up. For this reason, manual secondary cleaning is often required, which is easy to cause danger to the staff, and the cleaning and collection operations are cumbersome.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a flap powder cleaning device for a powder spraying chamber which has a simple structure and can effectively ensure that the powder on the flap is cleaned.

In order to achieve the above object, the utility model adopts the following scheme:

A flap powder cleaning device for a powder spraying chamber, comprising left and right flaps arranged at the bottom of the powder recovery chamber, and a double rocker mechanism that controls opening or closing of the flaps is connected to the left and right flaps , the left and right flaps respectively form draft slits with the side panels on both sides of the powder recovery chamber, and it is characterized in that: on the top of the connection of the left and right flaps, there is a The powder on the surface of the plate is blown into the air knife powder cleaning device at the bottom of the powder recovery chamber 1.

A flap powder cleaning device for a powder spraying room as described above is characterized in that the air knife powder cleaning device includes an air nozzle arranged on the top of the connection between the left and right flaps. , The inner side of the right flap is provided with an air supply channel connected with the air nozzle, and the air supply channel is connected with the exhaust pipe.

A flap powder cleaning device for a powder spraying room as described above is characterized in that the double rocker mechanism includes a rotating member, and one end of the rotating member is hinged to the powder recovery chamber through a hinge shaft. On the chamber, connecting rods are respectively hinged on the rotating parts on both sides of the hinge shaft, rockers are respectively hinged on one end of the connecting rods, and the rockers are respectively hinged on the left and right flaps. , a drive cylinder is connected to one end of the rotating member.

In summary, the utility model has the beneficial effects relative to the prior art as follows:

In the utility model, an air nozzle is provided on the air knife powder cleaning device at the top of the left and right flaps, and the air nozzle is connected with the left and right flaps, the side plates on both sides and the air draft slits formed by the bottom plate. The slit communicates with the exhaust pipe, and the exhaust pipe is connected with the fan. When the powder on the flap is regularly cleaned, the electromagnetic air valve is opened to allow the compressed air in the air storage tank to flow to the air nozzle, thereby forming an air knife on the surface of the flap to effectively blow the powder on the surface of the flap to the powder recovery chamber And it is recycled after being sucked away by the fan. The structure is simple and the cleaning effect is good.
