For example, the lifting device is a mechanical arm, the mechanical arm can be a four-axis mechanical arm, a six-axis mechanical arm and the like, and the mechanical arm can be selected according to actual needs.
The roll coating execution device 100 is a direct execution unit for executing roll coating construction on a wall surface, and specifically, roll coats a fluid paint such as emulsion paint on the wall surface. As shown in fig. 1, a roll coating execution device 100 is shown in an embodiment of the present application, where the roll coating execution device 100 includes: the roller coating device comprises a roller coating actuating mechanism 10 and an adjustable constant force mechanism 20, wherein the roller coating actuating mechanism 10 is connected with the adjustable constant force mechanism 20. The adjustable constant force mechanism 20 provides the pressure required to press the roll coating actuator 10 against a wall surface.
With continued reference to fig. 1, 2 and 4, the roll coating actuator 10 is used to perform a roll coating operation on a wall surface; the adjustable constant force mechanism 20 comprises an air source 21, an air path switching element 22, a pressure control assembly 23 and a cylinder module 24, wherein the air source 21 is communicated with the air path switching element 22 through a pipeline, the air source 21 is communicated with the pressure control assembly 23 through a pipeline, and the air path switching element 22 is communicated with the cylinder module 24 through a second pipeline 26; the air path switching element 22 is also in line communication with the pressure control assembly 23, and the pressure control assembly 23 is in line communication with the cylinder module 24 through a first line 25.
In summary, the implementation of the technical solution of the present embodiment has the following beneficial effects: the roller coating execution device 100 of the above scheme is applied to roller coating operation equipment, and is specifically used as a terminal execution unit of the roller coating operation equipment to complete roller coating construction on the inner and outer wall surfaces of a building. When the roller coating actuating mechanism 10 is not in a working state, the air path switching element 22 leads the air flow output by the air source 21 into the second pipeline 26, the air flow flows into the air cylinder module 24 through the second pipeline 26, and the air cylinder module 24 performs recovery action to drive the roller coating actuating mechanism 10 to be far away from the wall surface. During the working state, the air path switching element 22 performs reversing action, the air flow output by the air source 21 is introduced into the first pipeline 25, the air flow flows into the air cylinder module 24 through the first pipeline 25, the air cylinder module 24 performs stretching action to drive the roller coating executing mechanism 10 to extend out and gradually approach to the wall surface until the air cylinder module contacts the wall surface, and on the basis, the lifting device of the roller coating operation equipment drives the roller coating executing device 100 to perform vertical or horizontal reciprocating motion, so that the roller coating operation can be performed on the wall surface.
In the roll coating construction process, when the roller coating actuator 10 contacts a concave part of a wall surface, because air flow is continuously introduced into the air cylinder module 24 through the first pipeline 25, enough continuous thrust can be generated to push the roller coating actuator 10 to extend out towards the wall surface, namely, the roller coating actuator is always contacted with the wall surface; in addition, when the convex part of the wall is contacted, the reverse thrust of the wall is increased on the cylinder module 24, the air pressure in the cylinder module 24 is increased, the air flow reversely flows out from the first pipeline 25, and due to the existence of the pressure control assembly 23, the pressure control assembly 23 carries out pressure relief and exhaust, so that the roller coating executing mechanism 10 can properly retreat after being adapted to the convex part of the wall, but can always be ensured to be effectively contacted with the wall. So far, in the roll coating operation process, the air cylinder module 24 can generate compressed air with constant pressure according to the fluctuation change of the wall surface to generate constant thrust to the roll coating executing mechanism 10, so that the pressure of the roll coating executing mechanism 10 contacting the wall surface is constant, the roll coating executing mechanism 10 can always effectively contact the wall surface, and the roll coating quality and the roll coating efficiency are ensured. Compared with the scheme of adopting a spring in the prior art, the scheme has the advantages that the telescopic stroke range of the roller coating actuating mechanism 10 is wide through air pressure control, the use performance is high, the influence of coating adhesion is avoided, the contact force of the roller coating actuating mechanism 10 on the wall surface is not influenced due to the change of the elastic coefficient, and the reliability is high.
With continued reference to fig. 4, in some embodiments, the cylinder module 24 is provided with a first air chamber 241 and a second air chamber 242, and the cylinder module 24 further includes a push rod movably disposed in the first air chamber 241 and the second air chamber 242, and the push rod is connected to the roll coating actuator 10; the air path switching element 22 is communicated with the first air chamber 241 through the second pipeline 26, and the pressure control assembly 23 is communicated with the second air chamber 242 through the first pipeline 25. It will be appreciated that the first air chamber 241 and the second air chamber 242 form an internal cavity of the cylinder module 24. The push rod includes a piston rod and a piston block, the piston block is slidably disposed in the first air chamber 241 and the second air chamber 242, one end of the piston rod is connected to the piston block, and the other end of the piston rod extends out of the cylinder module 24 and is connected to the roller coating actuator 10.
When the air flow is introduced into the first air chamber 241 through the second pipeline 26, the air pressure in the first air chamber 241 is increased, the piston block is pushed to move towards the second air chamber 242, the piston block drives the piston rod to retreat, the roller coating executing mechanism 10 is pulled to be away from the wall surface, so that the roller coating executing device 100 is contracted and gathered, the transition is convenient to carry out, or the machine is stopped for a long time to avoid collision with an external object, and the safety is ensured. When the air flow is introduced into the second air chamber 242 through the first pipeline 25, the air pressure in the second air chamber 242 is increased, the piston block is pushed to move towards the first air chamber 241, the piston block pushes the piston rod to extend out, the piston rod pushes the roller coating executing mechanism 10 to extend out towards the wall surface and finally contact the wall surface, and therefore the roller coating executing mechanism 10 performs roller coating operation on the wall surface.
It can be understood that, in the roll coating operation process, a dynamic balance relationship is formed between the reverse thrust applied by the wall to the roll coating executing mechanism 10 and the air flow pressure introduced into the second air chamber 242 under the cooperation of the pressure control assembly 23, that is, the push-out pressure applied to the roll coating executing mechanism 10 in the second air chamber 242 is always ensured to be balanced with the reaction force applied by the wall, the roll coating executing mechanism 10 can stretch and float along with the fluctuation change of the wall, the roll coating executing mechanism 10 is ensured to be always in contact with the wall, and the roll coating quality and efficiency are ensured.
It should be noted that the piston block should form a complete partition effect on the first air chamber 241 and the second air chamber 242, so as to prevent the air flow series flow between the first air chamber 241 and the second air chamber 242 from affecting the flexibility of the roller coating actuator 10, reducing the pressure maintaining capability, and affecting the contact pressure of the roller coating actuator 10 on the wall surface.
In some embodiments, the gas path switching element 22 is provided as a solenoid directional valve. For example, in this embodiment, the electromagnetic directional valve specifically adopts a three-position two-way electromagnetic valve. The three-position two-way solenoid valve is electrically connected with the electric cabinet, and is provided with two switchable air flow channels which are respectively connected with the second pipeline 26 and the first pipeline 25. In an electrified state, the three-position two-way solenoid valve can perform channel switching to realize that the first pipeline 25 is closed while being communicated with the second pipeline 26, or the second pipeline 26 is closed while being communicated with the first pipeline 25, so that the working state of the cylinder module 24 can be regulated and controlled, and the roller coating executing mechanism 10 can complete roller coating, recovery transition and other work. The electromagnetic directional valve is controlled by an electric signal of the electric control box, has high response speed and high sensitivity, and is beneficial to the roller coating executing mechanism 10 to finish high-efficiency work and action switching.
With continued reference to fig. 1, 2 and 4, in some embodiments, the pressure control assembly 23 includes a relief valve 231 and a pressure reducing valve 232, the pressure reducing valve 232 is respectively communicated with the air passage switching element 22 and the cylinder module 24, and the relief valve 231 is in pipeline communication with the pressure reducing valve 232. During roller coating operation, when a reverse thrust is applied to the wall surface, the air flow in the second air chamber 242 is discharged after flowing back through the overflow valve 231, so that the roller coating actuator 10 can adapt to the convex part of the wall surface and can be ensured to be always in contact with the wall surface. The roller coating executing mechanisms 10 with different sizes are replaced according to different roller coating requirements, when the requirements for the roller coating pressure are different, the pressure reducing valve 232 and the overflow valve 231 are cooperatively matched, so that the air pressure in the air cylinder module 24 can be adjusted, the purpose of adjusting the roller coating pressure of the roller coating executing mechanisms 10 is achieved, and the roller coating consistency is ensured.
It will be appreciated that the roll coating pressure F = P × S (P is the compressed air pressure in the cylinder module 24 and S is the area of the piston block of the cylinder module 24) against the wall surface.
In addition, on the basis of any of the above embodiments, the cylinder module 24 includes at least two cylinders 243, the roll coating actuator 10 includes at least two roll coating modules 11, and the cylinders 243 are connected to the roll coating modules 11 in a one-to-one correspondence manner. Through arranging at least two roller coat modules 11 simultaneously, can greatly increased with the area of contact of wall, and then improve the roller coat efficiency of unit interval. And each roller coating module 11 is independently provided with one air cylinder 243, so that each roller coating module 11 can be ensured to be adapted to the concave-convex shape change of the wall surface and always effectively contact the wall surface, and the roller coating quality is ensured.
