Description

Technical Field

[0001] This invention relates to the field of spraying, and more particularly to a pneumatic house spraying device. Background Technology

[0002] Large factory buildings typically occupy a large area, sometimes thousands of square meters. Consequently, their roofs also have a large area. When maintaining the roofs of such large factory buildings, it is necessary to first clean off dust and debris before spraying or painting.

[0003] Currently, roof painting of factory buildings is mostly done manually. This is because using electric equipment on such large factory buildings can easily cause static electricity explosions, leading to safety accidents. Therefore, these factory buildings, which are thousands of square meters in size, can only be painted manually. However, manual painting is extremely costly and time-consuming. Nowadays, bidding prices often cost millions to tens of millions of yuan and several months of work time.

[0004] Therefore, it is necessary to design a pneumatic house spraying equipment. Summary of the Invention

[0005] To address the technical deficiencies in the background technology, this invention proposes a pneumatic roof spraying device. This device uses a pneumatic method to spray factory roofs, driven by a pneumatic motor and powered by an external air supply mechanism. This allows the pneumatic roof spraying device to spray factory roofs and, in conjunction with a painting device, achieves semi-automatic operation, thereby enabling rapid spraying of factory roofs and significantly reducing the cost and time of manual labor.

[0025] The embodiments of the present invention will be described below with reference to the accompanying drawings and related examples. The embodiments of the present invention are not limited to the following examples, and the present invention relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0026] See Figure 1-5 A pneumatic roof painting device is disclosed for spraying or painting the roofs of large factory buildings. The device includes a frame 1, a housing 2, a drive unit, and a painting unit. The frame 1 supports the various components of the device and houses the connecting air pipes and paint pipes 10. The housing 2 holds 15L of paint. The drive unit propels the device forward or backward. The painting unit sprays paint onto the roof. The frame 1 is covered by an integrated protective shell 3, which prevents dust from entering the device. The top of the protective shell 3 has an outer cover, which allows for device adjustments.

[0027] The housing 2 is housed within the protective shell 3 and fixedly connected to the frame 1. The drive unit is located at the bottom of the frame 1 and provides power to it. The painting device is located at the front end of the frame 1 and connected to the housing 2. The drive unit includes a pneumatic motor 4, two drive wheels 5, and two driven wheels 6. The use of the pneumatic motor 4 prevents static electricity. The pneumatic motor 4 is fixedly connected to the bottom of the frame 1. The drive wheels 5 and driven wheels 6 are both located at the bottom of the frame 1. The two drive wheels 5 are connected to the drive end of the pneumatic motor 4 via a rotating shaft 7. The pneumatic motor 4 drives the drive wheels 5 to rotate via the drive shaft, thereby providing power for the equipment to move forward or backward. A main air pipe connector 8 is provided on one side of the protective shell 3. The main air pipe connector 8 is connected to the input end of the pneumatic motor 4 via an air pipe. The main air pipe connector 8 is connected to an external air supply mechanism, thereby providing power for the equipment to move and to paint.

[0028] In one embodiment of the present invention, a switching switch 9 is provided at both the front and rear ends of the frame 1. The switching switch 9 is used to switch the forward and reverse rotation of the pneumatic motor 4. The forward and backward movement of the equipment can be controlled by the switching switch 9.

[0029] The input end of the painting device is equipped with an atomizing device, which is connected to the output end of the container 2 via a paint pipe 10. The atomizing device atomizes the paint in the container 2 through the paint pipe 10 and inputs it into the input end of the painting device so that the painting device can operate.

[0030] The painting device includes a painting bracket 11, a flat painting module, and a groove painting module. The painting bracket 11 is connected to the frame 1 via two connecting columns 12. Both the flat painting module and the groove painting module are connected to the painting bracket 11, and their input ends are connected to an atomizing device. The atomizing device inputs the atomized paint into the flat painting module and the groove painting module. The flat painting module is used for spraying the sides and the flat surface of the roof tile, while the groove painting module is used for spraying the inner walls of the grooves on both sides of the roof tile. The combination of the flat painting module and the groove painting module can make the roof painting more uniform and aesthetically pleasing.

[0031] In another embodiment of the present invention, the top of the frame 1 is provided with an adjustment mechanism 13, and the front end of the protective shell 3 is provided with two grooves. The connecting column 12 passes through the grooves and is connected to the driving end of the adjustment mechanism 13.

[0032] The planar spray painting module includes several planar nozzles 14, all of which are located at the front end of a support frame. The front end of the support frame is equipped with several adjustable valves 15, which are connected to the input terminals on one side of each planar nozzle 14. The bottom end of each planar nozzle 14 is provided with a paint inlet 16 and an air inlet 17. The paint inlet 16 is connected to the receiving box 2 via an atomizing device, and the air inlet 17 is connected to the main air pipe connector 8 via an air pipe. One side of each planar nozzle 14 is equipped with an adjustment knob 18 for adjusting the atomization level. The adjustment knob 18 allows for adjustment of the atomization length. Through the cooperation of the paint inlet 16 and the air inlet 17, the planar nozzle 14 can spray the atomized paint onto the roof.

[0033] The grooved spraying module includes several grooved nozzles 19 and connectors 20. The grooved nozzles 19 are connected to a support via the connectors 20, and each grooved nozzle 19 is connected to an input end on one side. The connectors 20 are movable, allowing adjustment of the spraying angle and range of the grooved nozzles 19 by adjusting their shape. The grooved nozzles 19 and the flat nozzles 14 have the same structure and are connected to the receiving box 2 and the main air pipe, respectively. The atomizing device includes a spray atomizing pipe 21, one end of which is connected to the receiving tank via a spray pipe, and the other end is connected to the flat nozzles 14 and the grooved nozzles 19 via a paint interface 16.

[0034] The pneumatic roof spraying equipment of this invention avoids static electricity through pneumatic drive, and the drive device and the spraying device work together to form a semi-automatic operation to achieve rapid spraying of factory roofs, which greatly reduces the cost and time of manual operation. The design of the adjustment mechanism 13 on the frame 1 and the adjustment knob 18 on the nozzle can be used for spraying at different angles and thicknesses. The cooperation of the flat nozzle 14 and the grooved nozzle 19 can make the roof spraying more uniform and beautiful.

[0035] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
