Description

Technical Field

[0001] The utility model belongs to the technical field of spraying process equipment, and particularly relates to a coloring spraying device. Background Technique

[0002] The thermal spraying process is a technology that uses a certain heat source to heat powder-shaped or wire-shaped metal or non-metal materials to a molten or semi-molten state, and then sprays them onto the surface of a pre-treated substrate at a certain speed by means of the flame flow itself or compressed air, and deposits them to form a surface coating with various functions. The thermal spraying process is widely used in mechanical manufacturing enterprises. The conventional thermal spraying process generally sprays pure-color coatings on the surface of workpieces. The colorant and the coating are usually pre-mixed evenly before spraying work is carried out.

[0003] For example, the patent document with the publication number "CN208494704U" discloses a new type of coloring spraying equipment for color tile production, including a base, a coloring spraying row structure, a cleaning shovel structure, an odor removal exhaust fan structure, a coloring chamber, a feeding pipe, a suspension rod, a driven wheel, a support rod, an impurity box, a socket, a motor, a main wheel, a guide belt, a support column and a control panel. The coloring spraying row structure is bolted to the middle position of the inner upper surface of the coloring chamber; the cleaning shovel structure is inserted into the socket; the odor removal exhaust fan structure is bolted to the upper surface of the right side of the base. Adopting the technical solution of this patent, using a circular stainless steel row is beneficial to evenly apply the coloring coating on the outer surface of the color tile and ensure the quality of the color tile; the setting of the exhaust fan is beneficial to discharge the odor during the coloring spraying process and ensure a clean working environment.

[0004] However, when spraying some workpieces with strange shape and structure features, sometimes it is necessary to master and understand whether the surface of the workpiece is completely covered by the coating, or whether the coating covering the surface of the workpiece is uniform. In order to enable the operator to promptly master the above relevant information, before spraying work, the coating and the temporary colorant need to be mixed, and then the coating containing the colorant is sprayed on the surface of the workpiece. The operator can understand and master the relevant information of whether the surface of the workpiece is completely covered by the coating or whether the coating covering the surface of the workpiece is uniform by observing the coloring situation of the workpiece surface with the naked eye. Finally, the colorant attached to the surface of the workpiece can be dissolved and removed by using the corresponding solvent. Under the above process requirements, when the coating and the temporary colorant cannot be pre-mixed evenly, they can only be mixed on-site, and the adhesion of the temporary colorant should be reduced as much as possible to facilitate the complete dissolution and removal of the colorant in the later stage. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a coloring spraying device.

[0006] The utility model is achieved through the following technical solutions.

[0007] The utility model provides a coloring spraying device, which comprises an air compressor, a liquid storage tank, a spray gun, a colorant supply pipe, a paint supply pipe and a spray pipe.

The other end of the colorant supply pipe extends into the liquid storage tank. An air supply pipe is connected between the air compressor and the liquid storage tank. A light-transmitting plate is arranged on the outer surface of the liquid storage tank.

Finally, the colorant attached to the surface of the workpiece can be dissolved and removed by using the corresponding solvent. Compared with the prior art, the colorant is stored in the liquid storage tank. When the operator carries out the spraying operation, the compressed air is used to drive the colorant to be transported into the spray pipe through the colorant supply pipe.

[0025] Adopting the technical solution of the present utility model, during the spraying operation, the temporary colorant and the coating can be mixed on-site and sprayed and adhered to the surface of the workpiece. The operator can understand and master whether the surface of the workpiece is completely covered by the coating or whether the coating covering the surface of the workpiece is uniform by observing the coloring situation of the workpiece surface with the naked eye. Finally, the colorant adhered to the surface of the workpiece can be dissolved and removed by using the corresponding solvent. Compared with the prior art, the colorant is stored in the liquid storage tank. When the operator carries out the spraying operation, the compressed air is used to drive the colorant to be transported into the spray pipe through the colorant supply pipe.

When the operator unscrews the sealing plug 12, the colorant can be fed through the liquid injection port, and then the colorant is evenly mixed with water under the pushing action of compressed air to form a colorant, and finally the colorant flows into the nozzle 6 along the colorant supply pipe 4 with the compressed air.

[0027] In addition, the paint spray gun 3 is also sleeved in a positioning ring 13.
