The application claims a japanning robot, it can replace the operation mode of traditional manpower manual brush floor lacquer, realizes automatic coating floor lacquer.

The painting robot mainly comprises a walking chassis, a dynamic mixing painting device and a paint supplying device, and also comprises a plurality of auxiliary accessories. The paint supplying device is used for supplying paint to the dynamic mixing painting device; the dynamic mixing painting device is used for uniformly stirring and mixing different types of paint and then pouring the paint on the ground; the walking chassis provides walking power for the painting robot to drive the dynamic mixed painting device to move and spray paint, so that the painting requirement of large-area ground is met.

The required floor paint of coating specifically is epoxy floor paint, and whole coating work progress need coat three kinds of coating paint in proper order, is priming paint, floating coat and finish paint respectively promptly. Each coating paint requires the mixing of two component paints in proportions such as the more common proportions of the primer consisting of the first component primer: the second component primer is obtained by mixing 1: 1; the intermediate coating paint consists of a first component intermediate coating paint: the second component is obtained by mixing the paint in a ratio of 5: 1; the finish paint is prepared from the following first component: and mixing the second component of finish paint with the ratio of 5: 1. Of course, it should be noted that the mixing ratio of the coating paints can be flexibly selected from 1:1 to 1:5 according to different use function requirements of different occasions.

The chemical components of the first component primer and the first component finish paint are similar, and the first component primer and the first component finish paint are both epoxy resin curing agents, so that the primer and the first component finish paint can be suitable for conveying by the same pipeline; similarly, the second component primer, the second component finish paint and the first component primer paint are all another epoxy resin curing agent, and the chemical components are similar, so that the two components can be conveyed by the same pipeline. And in the above case, cross contamination does not occur to cause material failure, so that the pipeline does not need to be cleaned.

In addition, the amount and viscosity of the second component primer, the second component top coat and the coating in the first component are minimum; the dosage and the viscosity of the first component primer and the first component finish paint are intermediate; while the amount and viscosity of the paint in the second component is maximized.

As shown in fig. 1, a dynamic hybrid painting apparatus is shown for one embodiment of the present application, which includes: mixer 10, first feed tube 20, second feed tube 30, and third feed tube 40. The mixer 10 is used to carry and secure the first feed pipe 20 to the third feed pipe 40 and to provide a place where different coating paints are mixed. The first feed line 20 to the third feed line 40 are each connected to a paint supply for feeding different coating paints into the mixer 10.

The mixer 10 is formed with a mixing and stirring chamber 11; the first feeding pipe 20, the second feeding pipe 30 and the third feeding pipe 40 are staggered and arranged on the mixer 10 and are communicated with the mixing and stirring cavity 11, and the inner diameters of the first feeding pipe 20, the second feeding pipe 30 and the third feeding pipe 40 are different or not identical.

In summary, the implementation of the technical solution of the above embodiment will have the following beneficial effects: the dynamic mixed painting device is applied to the painting robot and used for realizing orderly and uniform mixing of three layers of floor paints with six components and executing coating operation. Specifically, the indexes such as the amount and viscosity of the six components of floor paint are different, that is, the amount and viscosity of the primer paint, the top paint and the primer paint of one component are small, the primer paint, the top paint and the primer paint of the other component can be conveyed and injected into the mixing and stirring cavity 11 of the mixer 10 through the first feeding pipe 20 and the second feeding pipe 30 with small pipe inner diameters, and the amount and viscosity of the primer paint of the other component are large, so that the primer paint and the primer paint of the other component can be conveyed and injected into the mixing and stirring cavity 11 through the third feeding pipe 40 with large pipe inner diameters. And because the chemical compositions of the primer paint, the finish paint and the intermediate paint are similar, the first feeding pipe 20 and the second feeding pipe 30 do not need to be cleaned or replaced when the primer paint, the finish paint and the intermediate paint are respectively injected in sequence, and the third feeding pipe 40 only needs to be independently injected into the other intermediate paint and does not need to be cleaned and replaced. Make the dynamic mixing painting device of this application satisfy the paint vehicle of different quantity and viscosity and carry the mixing requirement, avoid causing the paint vehicle extravagant, the simple operation is used simultaneously, does benefit to and improves work efficiency.

Specifically, because the amount and viscosity of the second component primer, the second component topcoat and the first component primer are relatively close to those of the first component primer and the first component topcoat, the inner diameter of the first feeding pipe 20 and the inner diameter of the second feeding pipe 30 can be designed or selected to be similar to each other, so as to reduce the cost and difficulty of pipe preparation. Since the amount and viscosity of the paint in the second component are relatively large, the inner diameter of the third feeding pipe 40 needs to be larger than the inner diameter of the first feeding pipe 20 and larger than the inner diameter of the second feeding pipe 30, so as to ensure that the conveying flow rate of the paint in the second component meets the use requirement. It should be noted that the specific sizes of the inner diameters of the first feeding pipe 20 to the third feeding pipe 40 can be selected according to the flow rate of each coating paint, and are not limited herein.

According to the construction requirements, in order to ensure the coating quality of each layer of coating paint on the premise of drying completely, the interval between the coating operations of each layer of coating paint is at least 8 hours or more. I.e., after the primer is applied, the basecoat is applied 8 hours apart and the topcoat is applied 8 hours apart (in some cases, there are two midcoats and two topcoats).

As shown in fig. 4, in summary, the working method and flow of the dynamic hybrid painting apparatus of the present application can be briefly described as follows:

s100: the first feeding pipe 20 and the second feeding pipe 30 are opened, and the third feeding pipe 40 is closed; through first inlet pipe 20 pours into first component priming paint into in the mixing chamber 11 of blender 10 into, through second inlet pipe 30 to pour into second component priming paint into in the mixing chamber 11, treat first component priming paint with second component priming paint is after preset proportion misce bene, follows discharge and water and spill to treating to paint subaerial formation priming paint layer in the blender 10. The so-called preset ratio can be found in the above.

S200: after the primer coating is completed, the second feeding pipe 30 is closed, the first feeding pipe 20 is kept open, and the first component primer continues to be injected into the mixing and stirring cavity 11 until the first component primer fills the whole mixing and stirring cavity 11. Therefore, the mixed primer originally remained in the mixing and stirring cavity 11 can be removed completely by virtue of the first component primer, and the pollution to the subsequent intermediate coating is avoided. It should be noted that the first component primer and the second component primer are solidified only after being uniformly mixed according to a preset proportion, namely, the solidification effect of coating the first component primer and the second component primer on the ground is achieved; while any one-component primer present does not cure.

S300: closing the first feed tube 20 while opening the second feed tube 30 and the third feed tube 40; through the second feed pipe 30 to pour into first component paint in the mixing and stirring chamber 11, through the third feed pipe 40 to pour into second component paint in the mixing and stirring chamber 11, wait that after first component paint with second component paint is the miscella according to predetermineeing the proportion miscella, follow discharge in the blender 10 and water and spill form the intercoat layer on the priming paint layer. At this time, since the second feeding pipe 30 still has the previous second component primer, the first primer can be extruded by introducing the first primer, so that the residual second component primer is discharged from the discharge hole 51 of the dispenser 50, and at this time, the second feeding pipe 30 does not need to be additionally cleaned or replaced, and since the second component primer is similar to the first component primer, cross contamination is not caused. In addition, during a period of time when the second feeding pipe 30 initially injects the first component primer, and a period of time when the third feeding pipe 40 initially injects the second component primer, the first component primer and the second component primer mainly act to extrude the original residual first component primer, so that the first component primer is firstly discharged from the discharge hole 51 of the dispenser 50; then, after the first component intermediate coating and the second component intermediate coating are injected continuously and mixed according to the preset proportion and fill the mixing and stirring cavity 11, the intermediate coating is normally coated on the primer layer, and the intermediate coating layer with uniform texture can be obtained.

It should be noted that the preset ratio can be understood by referring to the foregoing.

S400: after the application of the intermediate paint is completed, the second feeding pipe 30 is closed, the third feeding pipe 40 is kept open, and the filling of the intermediate paint of the second component into the mixing and stirring cavity 11 is continued until the intermediate paint of the second component fills the whole mixing and stirring cavity 11. In a similar way, the mixed intermediate painting originally remained in the mixing and stirring cavity 11 can be completely removed by virtue of the intermediate painting of the second component, so that the pollution to the subsequent finish paint is avoided. It should be noted that the paint in the first component and the paint in the second component are solidified only after being uniformly mixed according to a preset proportion, and the effect of coating the paint on the ground is achieved; any one-component basecoat is present and does not set.

S500: closing the third feed tube 40 while opening the first feed tube 20 and the second feed tube 30; through first inlet pipe 20 to pour into first component finish paint into in the mixing and stirring chamber 11, through second inlet pipe 30 to pour into second component finish paint into in the mixing and stirring chamber 11, wait first component finish paint with after the second component finish paint misce bene, follow discharge and water in the blender 10 and arrive form the finish paint layer on the well coating layer, so far accomplish the painting work. At this time, the introduced first component top paint can extrude the first component primer remained in the first feeding pipe 20, so that the remained first component primer is discharged from the discharge hole 51 of the distributor 50, and at this time, the first feeding pipe 20 does not need to be additionally cleaned or replaced. Similarly, the introduced second component finish paint can extrude and completely discharge the residual second component paint in the second feeding pipe 30 from the discharge hole 51 of the distributor 50. And then the first component finish paint and the second component finish paint are continuously injected, and can be poured on the intermediate paint layer to form a finish paint layer after being mixed according to a preset proportion.

It should be noted that, in order to ensure the continuous normal operation of the dynamic mixing coating device, after the finish coating is completed, the second feeding pipe 30 is closed to stop feeding the second finish, and the first feeding pipe 20 is kept to continuously feed the first finish until the first finish fills the whole mixing and stirring chamber 11, so as to prevent the paint from being solidified in the mixing and stirring chamber 11 and causing blockage.

When the area of the bottom surface needing coating is large, the steps can be circulated, and the layered coating in different regions is realized to meet the processing requirement.

As described in the scheme, the quality and the coating effect of the floor paint can be ensured only after the primer, the intermediate paint and the finish paint with different components are uniformly mixed according to the preset proportion.
