The plate 300 is placed on the fixing frame 400, and the spraying pump 52 pumps the spraying material out of the storage barrel 100 and into the spraying barrel 6; after that, the spray paint is sprayed from the spray can 6 onto the plate material 300 in a line shape. And when spraying, the lifting motor is started to enable the spraying cylinder 6 to descend or ascend at a constant speed in a horizontal posture, so that surface spraying is realized. The spray paint can be selected from paint, lacquer or pigment according to actual needs.

The spraying operation on the surface of the panel is quickly and uniformly realized by lifting the spraying cylinder 6 in a horizontal posture. The spraying speed is high, the spraying area is flexible and controllable, and the spraying efficiency of a construction site is greatly improved.

Preferably, the bottom of the bearing box 5 is provided with rollers, so that the bearing box is convenient to move.

Further, a mixing tank 200 is also arranged on the bearing box 5; the mixing tank 200 is connected with the material storage barrel 100; the mixing tank 200 mixes materials in real time and continuously stirs to avoid precipitation or layering of the sprayed materials, and the stable quality of the sprayed materials is ensured. The storage barrel 100 can also be reduced in size appropriately, so that the spray paint can be guided into the mixing tank 200 in real time according to the requirement, and waste caused by excessive storage is avoided.

Since the viscosity of the spray paint is too high to affect the spraying effect, the viscosity is required to be stable. To solve this problem, the mixing bowl 200 of the present invention is modified as follows.

Referring to fig. 5 and 6, the mixing tank 200 of the present invention comprises a tank body 1, wherein a stirrer is arranged in the tank body 1; the stirrer comprises a rotating pipe 11, and 3-5 layers of stirring rods 12 are arranged on the rotating pipe 11; referring to fig. 9, the rotating tube 11 and the stirring rod 12 are both hollow structures and are communicated with each other; a plurality of liquid outlets are arranged on the stirring rod 12; the liquid material fed from the rotating pipe 11 can enter the tank body 1 through the liquid outlet. The liquid material can be a thinner or a viscosity reducer.

Referring to fig. 6, the top of the tank 1 is further provided with a slewing bearing 13 and a fixed frame 14; the fixed frame 14 is fixedly provided with a stirring motor 15; the rotating pipe 11 is connected with the rotary support 13 in a penetrating way and is in transmission connection with the stirring motor 15; realizing the smooth rotation thereof.

The fixed frame 14 is also fixed with a fixed tube 2; referring to fig. 7, the lower end of the fixed pipe 2 is rotatably connected with a rotating pipe 11; the port positions of the rotating pipe 11 and the fixed pipe 2 are respectively provided with a first flanging 111 and a second flanging 24; a plurality of rolling balls 25 are clamped between the first flanging 111 and the second flanging 24; the rotation of the rotating pipe 11 with respect to the fixed pipe 2 is achieved.

A piston block 21 is movably arranged in the fixed pipe 2; the rotating pipe 11 and the fixed pipe 2 are also internally provided with a mandril 3 which is abutted against the piston block 21 in a penetrating way; a liquid feeding pipe 23 is also connected to the side wall of the fixed pipe 2.

When the ejector rod 3 moves upwards, the piston block 21 is ejected; the fixed pipe 2 is communicated with the liquid feeding pipe 23, and liquid materials can be fed into the tank body 1 through the liquid feeding pipe 23; preferably, the pipe body of the liquid feeding pipe 23 is also provided with an air inlet branch pipe 231; and (3) introducing compressed gas with certain pressure while adding the liquid material to promote the liquid material to quickly enter the tank.

Referring to fig. 8, when the ejector rod 3 moves downwards, the piston block 21 falls down to block the communication between the fixed pipe 2 and the liquid feeding pipe 23; the addition of liquid material to the tank can be stopped. Preferably, the inner wall of the fixed pipe 2 is further provided with a limit stop 26 to prevent the piston block 21 from falling.

Preferably, the top of the fixed pipe 2 is connected with a vent pipe 22; the upper limit force of the piston block 21 to be lifted is increased by introducing compressed air of a predetermined pressure into the vent pipe 22. The threshold for the piston block 21 to be lifted can be adjusted by adjusting the pressure of the introduced compressed air.

Referring to fig. 10, a detection head 4 is arranged at the lower end of the rotating pipe 11, and the detection head 4 is fixedly connected with a rotating shaft 41; the rotating shaft 41 is rotatably connected with the rotating pipe 11 through a bearing; the inner wall of the rotating pipe 11 is also sleeved with a sleeve 32 in a threaded manner; the top of the sleeve 32 is fixedly connected with the lower end of the mandril 3; the detection head 4 is also provided with a blade 42.

Referring to fig. 11, at least 3 sliding bars 43 are uniformly and annularly arranged on the outer wall of the rotating shaft 41; the inner wall of the sleeve 32 is correspondingly provided with a sliding groove in which the sliding strip 43 is embedded; when the rotating shaft 41 rotates relative to the rotating pipe 11, the sleeve 32 is driven to rotate, so that the sleeve 32 slides in the axial direction relative to the rotating shaft 41.

When the viscosity of the spray paint in the tank is less than a certain preset value, the detection head 4 and the rotating pipe 11 synchronously rotate; at this time, the piston block 21 blocks the fixed pipe 2 from the charging pipe 23. At this time, the piston block 21 applies a large pressure to the rod 3, and therefore the detection head 4 is also prevented from rotating relative to the rotating tube 11.

When the viscosity of the spray coating in the tank is larger than a certain preset value, the viscosity resistance generated by the high-viscosity material enables the detection head 4 and the rotating pipe 11 to rotate relatively, so that the sleeve 32 rotates and rises relative to the rotating pipe 11, and the ejector rod 3 ejects the piston block 21; the liquid feeding pipe 23 is communicated with the fixed pipe 2, and liquid materials such as viscosity reducer enter the tank through the rotating pipe 11 and are rapidly mixed with the spray coating in the tank under the continuous stirring of the stirring rod 12, so that the viscosity is reduced and the preset value is returned.

Preferably, the top end of the top rod 3 is provided with a ball 31 to reduce the friction force when the top rod rotates relative to the piston block 21.

Preferably, the liquid outlet of the stirring rod 12 is communicated with a stirring branch pipe 16; liquid material gets into jar body 1 from stirring branch pipe 16, and stirring branch pipe 16 has the stirring effect simultaneously, makes liquid material get into jar back and mix with the spraying material in jar rapidly to in time reduce viscosity, improve stirring efficiency.

Preferably, referring to fig. 12, the detection head 4 has a spherical cambered surface structure; the vanes 42 are preferably circular arc shaped and evenly arranged around a spherical arc surface structure. The sensitivity of sensing the viscosity of the spray coating is improved, and the stress is uniform when the detection head 4 and the rotating pipe 11 rotate relatively.

As an example, the detection head 4 of the present invention is disposed at the bottom of the rotating pipe 11 and is coaxial with the rotating pipe 11. Therefore, when the viscosity of the paint at the detection head 4 is reduced to a preset value, it can be considered that the paint in the entire can body 1 is uniformly stirred and reaches the preset viscosity.

Therefore, in order to timely shut off the filler pipe 23, referring to fig. 13, the rotating shaft 41 is also in transmission connection with a rotating assembly; when the viscosity of the paint in the tank is reduced to a preset value, the rotating assembly makes the rotating shaft 41 rotate reversely, so that the sleeve 32 rotates reversely and descends spirally, the ejector rod 3 descends, and the piston block 21 falls to block the communication between the liquid feeding pipe 23 and the fixed pipe 2.

Further, the rotating assembly comprises a shaft seat 33 fixedly arranged on the inner wall of the rotating pipe 11; a gear shaft 35 is rotatably arranged on the shaft seat 33, and the gear shaft 35 is fixedly sleeved with a rotary gear 34; the rotary gear 34 is in transmission connection with a rotary gear ring 44 fixedly sleeved on the outer wall of the rotating shaft 41; a torsion spring connected with the rotating shaft 41 is further arranged in the shaft seat 33.

When the viscosity of the spray coating is too high, the rotating shaft 41 rotates forwards and drives the gear shaft 35 to rotate, so that the torsion spring stores energy; when the viscosity of the spray paint is reduced, the viscous force is reduced, and the torsion spring releases energy to enable the gear shaft 35 to rotate reversely, so that the rotating shaft 41 rotates reversely, and the liquid feeding pipe 23 and the fixed pipe 2 are cut off.

The rotating assembly is connected through the rotating shaft 41, so that the rotating assembly can timely perform corresponding actions according to the viscosity of the spray paint in the tank, the connection or disconnection between the liquid feeding pipe 23 and the fixed pipe 2 is realized, the viscosity of the spray paint in the tank is timely adjusted, the spray paint is maintained in a stable numerical value or a controllable fluctuation range, and the mixing efficiency and quality are improved.

The mixing tank 200 is characterized in that a hollow rotating pipe is arranged in the tank and is respectively communicated with a stirring rod positioned in the tank and a fixed pipe positioned outside the tank; liquid materials are added into the tank from the hollow rotating pipe, and the liquid materials can be stirred and mixed with the spray paint in the tank after being added, so that the mixing efficiency and the mixing effect are improved. The invention also arranges a detection head at the bottom of the rotary tube; when the viscosity of the spray coating in the tank is too high, the spray coating is fed into the tank from the fixed pipe at once, and the viscosity of the spray coating in the tank is adjusted in time, so that the spray coating is maintained in a stable numerical value or a controllable fluctuation range, and the mixing efficiency and quality are improved.

In summary, the invention provides a rapid spraying device for building boards, which pumps the spraying material into a spraying cylinder through a spraying pump and sprays the spraying material onto the boards in a linear manner. And the lifting motor is started to enable the spraying barrel to descend or ascend at a constant speed in a horizontal posture during spraying, so that surface spraying is realized.
