DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 to Figure 3 In the embodiment of the utility model, a building decoration sprayer comprises a support base 1 with a sandwich in the middle, a plunger pump 2 and a barrel 5 are installed at the top of the support base 1, the input end of the plunger pump 2 is connected to the bottom end of the barrel 5 through an output pipe 4, the output end of the plunger pump 2 is connected to a connecting pipe 10 through an input pipe 3, the bottom end of the barrel 5 is a hollow conical structure, and the bottom end of the barrel 5 penetrates into the sandwich cavity of the support base 1, the top end of the barrel 5 is detachably connected with a barrel cover 6, and the top end of the barrel cover 6 is installed with a scraping mechanism that penetrates the inner wall of the barrel 5, and a lifting mechanism extending to the top of the support base 1 is installed in the sandwich cavity of the support base 1;

[0025] The scraping mechanism is used to scrape off the paint attached to the inner wall of the barrel 5, thereby improving the utilization rate of the paint;

[0026] The lifting mechanism is used to drive the barrel cover 6 and the scraping mechanism connected to the barrel cover 6 to move up and down.

[0027] In this embodiment: when the device is used to spray the surface of a building, the paint is first poured into the material barrel 5, at which time the barrel cover 6 is in a closed state, and the scraping mechanism is first started to fully stir the paint;

[0028] After sufficient stirring, the plunger pump 2 is started. When the piston in the plunger pump 2 moves downward, negative pressure is generated, and the paint in the barrel 5 is sucked into the inner cavity of the plunger pump 2 through the input pipe 3. When the piston in the plunger pump 2 moves upward, the paint in the plunger pump 2 is pushed into the output pipe 4, and the paint is pressurized in the process.

[0029] It should be noted that: both the input and output ends of the plunger pump 2 are provided with ball seat one-way valves, the one-way valve at the input end allows the input pipe 3 to only flow in but not out, and the one-way valve at the output end allows the output pipe 4 to only flow out but not in.

[0030] Please refer to Figure 2 , Figure 3 The scraping mechanism includes a rotary motor 11 mounted on the top of the barrel cover 6, and the output end of the rotary motor 11 passes through the bottom end of the barrel cover 6 and is connected to a rotary shaft 16;

[0031] The rotating shaft 16 is connected to an upper scraper plate 17 and a lower scraper plate 18 through connecting rods. The rotating upper scraper plate 17 is used to scrape the columnar inner wall of the barrel 5, and the rotating lower scraper plate 18 is used to scrape the vertebral inner wall of the barrel 5.

[0032] In this embodiment: when the paint is poured into the material barrel 5, the rotating motor 11 is started, the rotating motor 11 drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the upper scraping plate 17 and the lower scraping plate 18 to rotate through the connecting rod to fully stir the poured paint;

[0033] Secondly, since the paint has good viscosity, part of the paint will adhere to the inner wall of the barrel 5 and will be relatively thick. Therefore, during the spraying process, the scraping mechanism can be started once in a while to scrape off the paint attached to the barrel 5. The scraped paint falls to the paint surface under the action of gravity, thereby improving the utilization rate of the paint.

[0034] Please refer to Figure 1 , Figure 2 and Figure 3 The lifting mechanism includes a shaft-holding motor 13 installed in the interlayer cavity of the support seat 1 through a mounting frame, the output end of the shaft-holding motor 13 is connected to a first synchronous wheel 12, and the first synchronous wheel 12 is connected to a second synchronous wheel 15 through a synchronous belt 14;

[0035] The top ends of the first synchronous wheel 12 and the second synchronous wheel 15 are both connected with a screw rod 9 penetrating to the top of the support seat 1, and the connection between the screw rod 9 and the support seat 1 is rotatably connected through a bearing;

[0036] The spiral groove of the screw rod 9 is formed on the outer wall of the screw rod 9 and is located above the support seat 1. The screw rod 9 is connected to a fixing plate 7 connected to the barrel cover 6 through the screw rod seat.

[0037] In this embodiment: after one type of paint is sprayed, when spraying other types or colors of paint, the power supply of the scraper mechanism is first disconnected, and then the shaft-holding motor 13 is started. The shaft-holding motor 13 drives the No. 1 synchronous wheel 12 to rotate, and the No. 1 synchronous wheel 12 drives the No. 2 synchronous wheel 15 to rotate through the synchronous belt 14. At this time, the No. 1 synchronous wheel 12 and the No. 2 synchronous wheel 15 respectively drive the screw rod 9 at the top thereof to rotate. When the screw rod 9 rotates, since the ball in the screw rod seat is always engaged with the spiral groove of its outer wall, the screw rod seat moves upward, and the screw rod seat drives the fixed plate 7 to move upward. The fixed plate 7 can drive the barrel cover 6 and the scraper mechanism installed on the barrel cover 6 to move upward as a whole until the distance between the barrel cover 6 and the material barrel 5 is sufficient to fully clean the surface of the scraper mechanism.

[0038] Please refer to Figure 1 and Figure 2 The diameter of the first synchronous wheel 12 is equal to the diameter of the second synchronous wheel 15, and transmission gear blocks are formed equidistantly on the inner wall of the synchronous belt 14. Tooth grooves are formed equidistantly on the first synchronous wheel 12, the second synchronous wheel 15 and the transmission gear blocks in the circumferential direction, and the tooth grooves are meshed with the transmission gear blocks.

[0039] In this embodiment: the tooth grooves and the tooth blocks increase the torque transmission efficiency during the transmission process and avoid slipping.

[0040] Please refer to Figure 1 A feed port 8 is installed on the top of the barrel cover 6, the inner cavity of the feed port 8 is connected to the inner cavity of the barrel 5, and the top of the feed port 8 is open;

[0041] The top of the barrel cover 6 is also provided with an air hole for exhausting air.

[0042] In this embodiment: when pouring the paint, first open the rubber plug connected to the pore, then pour the paint into the barrel 5 through the feed port 8. As the paint enters, the gas in the barrel 5 is discharged. After the paint is added, use the rubber plug to plug the pore.

[0043] Please refer to Figure 1 The output end of the connecting pipe 10 is connected with a spray gun.

[0044] In this embodiment: the paint pressurized by the plunger pump 2 enters the spray gun through the connecting pipe 10. By opening the channel of the spray gun, the high-speed flowing high-pressure paint comes into contact with the slow-flowing air from the outside. The air forms resistance to the paint, and the paint is dispersed under the resistance and then adheres to the surface of the building.

[0045] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
