Description

Technical Field

[0001] The utility model relates to the technical field of painting, in particular to a painting device for a large-space factory building. Background Art

[0002] Currently, the most common method for painting factory buildings is manual brushing. This method is simple to operate and highly flexible, making it particularly suitable for small, irregularly shaped, or complex factory buildings. With skilled techniques, workers can evenly apply paint to the steel structure, forming a smooth, uniform film. However, manual brushing is inefficient and can be time-consuming and labor-intensive for large factory buildings.

[0003] After searching, the patent with application number CN201611109950.3 discloses a discharge brush head and a brushing device, wherein the discharge brush head includes a brush head seat, a brush head cover and a valve. The brush head seat is provided with a brush seat inlet cooperating with the feeding assembly, and a brush seat outlet connected to the brush seat inlet. The brush head cover is fixed to the brush head seat and includes a discharge head and a connecting pipe connecting the brush head seat and the discharge head. The connecting pipe includes an extension part connected to the brush head seat and extending along the opening direction of the brush seat outlet and having elastic recovery, and a pressing part connected to the tube end of the extension part away from the brush head seat and extending inward. Through the brush head seat, brush head cover and valve setting, the discharging brush head can discharge material when the discharging head is subjected to an external force perpendicular to the direction of the brush seat outlet opening, and the discharging time of the discharging brush head can adapt to the brushing operation time of the discharging brush head, and will not discharge material during non-brushing action time; however, this device is also prone to uneven discharging, or failure to work smoothly when subjected to uneven external force, and uneven smearing.

[0004] Moreover, modern large-space steel structure workshops are usually composed of larger and wider components, such as steel plate walls, flat steel columns, etc. When painting these components, they often face problems of low operating efficiency and inconvenience.

[0005] Therefore, a large-space factory painting device is proposed to solve the above problems. Utility Model Content

Bristles 1003 are provided on the top of the rubber seat 1002. When the operating rod 1 is held and pressed hard, the brush head 10 is first subjected to force. After the liquid outlet shell 1001 is subjected to force, it compresses the inner shell 5. At the same time, the second one-way valve 1004 will open, and the paint in the liquid storage chamber 9 will flow into the liquid outlet chamber 1005. When the pressure is released, the paint in the liquid outlet chamber 1005 can flow out through the liquid outlet capillary holes 1006 provided on the rubber seat 1002 and be brushed through the brush bristles 1003.

[0026] When the inner shell 5 slides up and down inside the outer shell 4, the pressure is balanced through the pressure equalizing hole 8. When the inner shell 5 continues to press hard, the inner shell 5 will be subjected to force and then slide inside the outer shell 4. The piston rod 3 and the piston head 6 are fixed, and the inner shell 5 slides relative to the outer shell 4. Under the action of internal pressure, the first one-way valve 11 opens and the paint in the liquid inlet pipe 2 flows into the liquid storage chamber 9. After the pressing state is released, the compression spring 12 returns to its original state from the pressed state, driving the inner shell 5 to return to its original position, and the first one-way valve 11 is closed; and the first one-way valve 11 and the second one-way valve 1004 both adopt spherical one-way valves; it can ensure that the paint flows unilaterally without overflowing, which can not only save paint but also make the construction process cleaner.
