Description

Technical Field

[0002] Spraying machine is a special coating equipment using spraying technology. The principle is to control the airflow to instantly push the air distribution reversing device to reverse, so that the piston of the pneumatic motor can make a stable and continuous reciprocating motion, pressurize the inhaled paint, and transport the paint to the spray gun of the spraying machine through a high-pressure hose. The spray gun instantly atomizes the paint and releases it to the surface of the object to be coated. Floor paint is made of oil, solvent and tree material. Floor paint can be divided into corrosive floor paint, elastic floor paint, decorative floor paint, load-bearing floor paint, etc. This kind of floor paint has the advantages of beauty, waterproof, anti-corrosion and wear resistance.

[0003] When floor paint is sprayed, the spraying area is large, so the feed pipe is long during spraying, which requires a larger feed pressure. The floor paint sprayer feeds through a feeding auger during use, and the feed pressure is low, which cannot meet the needs of large-area spraying operations, affecting the spraying efficiency of the floor paint. In order to solve the above problems, a feeding mechanism for a floor paint sprayer is proposed in this application. Utility Model Content

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0027] like Figure 1-5 As shown, a feeding mechanism of a floor paint sprayer proposed by the utility model comprises a storage box 1, the bottom of the storage box 1 is conductively connected to a feed port 2, the feed port 2 is an inverted cone structure, one end of the bottom surface of the feed port 2 is conductively connected to a No. 1 feed pipe 3, the other end of the bottom surface of the feed port 2 is conductively connected to a No. 2 feed pipe 4, the No. 1 feed pipe 3 and the No. 2 feed pipe 4 are symmetrically arranged;

[0028] A first solenoid valve 5 is installed at the bottom of the first feed pipe 3, and a second solenoid valve 6 is installed at the bottom of the second feed pipe 4;

[0029] A hydraulic rod 8 is provided at a position in the inner cavity of the storage box 1 corresponding to the positions of the No. 1 feeding pipe 3 and the No. 2 feeding pipe 4, and the piston rod ends of the hydraulic rod 8 are connected to piston heads 9.

[0030] It should be noted that, when the floor paint is added into the storage box 1, the floor paint is guided through the discharge port 2 of the conical structure, and under the cooperation of gravity, the floor paint flows into the No. 1 feeding pipe 3 and the No. 2 feeding pipe 4 respectively, and the No. 1 solenoid valve 5 and the No. 2 solenoid valve 6 work alternately. When the No. 1 solenoid valve 5 is opened, the No. 2 solenoid valve 6 is in a closed state, and the corresponding hydraulic rod 8 pushes the piston head 9 to insert into the No. 1 feeding pipe 3. The floor paint in the No. 1 feeding pipe 3 can be pressed into the summary discharge pipe 7 through the piston head 9, and then the No. 1 solenoid valve 5 and the No. 2 solenoid valve 6 are opened. When the No. 1 solenoid valve 5 is closed, the corresponding hydraulic rod 8 contracts, allowing the floor paint to continue to flow into the No. 1 feeding pipe 3. When the No. 2 solenoid valve 6 is opened, the corresponding hydraulic rod 8 pushes the piston head 9 to insert into the No. 2 feeding pipe 4, and discharges the floor paint in the No. 2 feeding pipe 4 through the collecting discharge pipe 7. By alternately feeding through the No. 1 feeding pipe 3 and the No. 2 feeding pipe 4, the feeding speed of the floor paint can be increased. At the same time, the feeding power is lifted by the hydraulic rod 8, so that a greater feeding pressure can be obtained in the feeding pipe, which can increase the feeding distance of the floor paint.

[0031] In this embodiment, if Figure 1 and Figure 2 As shown, the bottom of the No. 1 feed pipe 3 and the No. 2 feed pipe 4 are connected with a tee pipe, and the bottom of the No. 1 feed pipe 3 and the No. 2 feed pipe 4 are connected with the collecting discharge pipe 7 through the tee pipe.

[0032] It should be noted that the floor paint discharged from the No. 1 feed pipe 3 and the No. 2 feed pipe 4 is collected through a tee pipe and discharged through the collecting discharge pipe 7.

[0033] In this embodiment, if Figure 2 and Figure 3 As shown, after the piston rod of the hydraulic rod 8 is extended, the piston head 9 is respectively plugged into the No. 1 feed pipe 3 and the No. 2 feed pipe 4, and the outer wall surface of the piston head 9 is sleeved with a rubber sealing ring 10, and the outer wall of the rubber sealing ring 10 is respectively abutted against the inner wall surface of the No. 1 feed pipe 3 and the No. 2 feed pipe 4, and a fixing frame 11 is welded in the middle of the top of the inner cavity of the storage box 1, and the fixing frame 11 spans the storage box 1, and the hydraulic rod 8 is symmetrically mounted on the fixing frame 11.

[0034] It should be noted that the hydraulic rod 8 can be fixed by the fixing frame 11, and the rubber sealing ring 10 can seal the connection between the piston head 9 and the inner walls of the No. 1 feed pipe 3 and the No. 2 feed pipe 4 to ensure the feed pressure of the floor paint.

[0035] In this embodiment, if Figure 5 As shown, a mounting frame 12 is welded adjacent to the No. 1 feed pipe 3 and the No. 2 feed pipe 4, and both ends of the mounting frame 12 are inner arc structures. The two ends of the mounting frame 12 are respectively in contact with the surfaces of the No. 1 feed pipe 3 and the No. 2 feed pipe 4 through the inner arc structures, and a vibration motor 13 is installed on the surface of the mounting frame 12.

[0036] It should be noted that the vibration generated by the vibration motor 13 during operation is transmitted to the No. 1 feed pipe 3 and the No. 2 feed pipe 4 through the mounting bracket 12. The air in the No. 1 feed pipe 3 and the No. 2 feed pipe 4 can be discharged through vibration, and the bubbles in the pipe can be reduced during feeding, thereby preventing the floor paint from bursting during discharge.

[0037] In this embodiment, if Figure 5 As shown, rubber shock-absorbing tubes 14 are installed at the connection points between the top of the No. 1 feeding pipe 3 and the No. 2 feeding pipe 4 and the discharge port 2.

[0038] It should be noted that the rubber shock-absorbing tube 14 can absorb vibrations, reduce the vibrations transmitted to the material storage box 1, and improve the stability of the feeding mechanism during use.

[0039] The working principle and use process of the utility model are as follows: the floor paint is poured into the storage box 1, the floor paint is guided through the discharge port 2 of the conical structure, and the floor paint flows into the No. 1 feeding pipe 3 and the No. 2 feeding pipe 4 respectively under the cooperation of the action of gravity, the No. 1 solenoid valve 5 and the No. 2 solenoid valve 6 work alternately, when the No. 1 solenoid valve 5 is opened, the No. 2 solenoid valve 6 is in a closed state, and the corresponding hydraulic rod 8 pushes the piston head 9 to insert into the No. 1 feeding pipe 3, and the floor paint in the No. 1 feeding pipe 3 can be pressed into the summary discharge pipe 7 through the piston head 9, and then the No. 1 solenoid valve 5 is closed, and the corresponding hydraulic rod 8 contracts, so that the floor paint can continue to flow into the No. 1 feeding pipe 3, the No. 2 solenoid valve 6 is opened, and the corresponding hydraulic rod 8 pushes the piston head 9 to insert into the No. 2 feeding pipe 4 The floor paint in the No. 2 feeding pipe 4 is discharged through the collecting discharge pipe 7. The feeding speed of the floor paint can be improved by alternating the feeding through the No. 1 feeding pipe 3 and the No. 2 feeding pipe 4. At the same time, the feeding power is lifted by the hydraulic rod 8, so that a larger feeding pressure can be obtained in the feeding pipe, which can increase the feeding distance of the floor paint. The vibration generated by the vibration motor 13 during operation is transmitted to the No. 1 feeding pipe 3 and the No. 2 feeding pipe 4 through the mounting frame 12. The air in the No. 1 feeding pipe 3 and the No. 2 feeding pipe 4 can be discharged through vibration. The bubbles in the pipe can be reduced during feeding, and the floor paint can be prevented from bursting during discharge. The rubber shock-absorbing tube 14 can absorb the vibration, reduce the vibration transmitted to the storage box 1, and improve the stability of the feeding mechanism during use.
