It is usually a viscous liquid made of resin, oil or emulsion, with or without pigments, fillers, and corresponding additives, and is prepared with organic solvents or water. When using organic solvents or water, they need to be transported.

[0003] When traditional delivery pumps transport liquid from one place to another, the liquid is prone to backflow, which will affect the normal delivery of the liquid. The impact of the backflow pressure and the delivery pressure will also cause damage to the internal parts of the pump, which is easy to cause damage to the delivery pump.

[0004] It should be noted that the information disclosed in this background technology section is only intended to increase understanding of the overall background of the present invention, and should not be regarded as an admission or in any form of implication that the information constitutes prior art already known to those skilled in the art. Therefore, the above content falls within the technical cognition of the inventor and does not necessarily constitute prior art. Utility Model Content

[0025] Please refer to Figure 1-Figure 3A liquid delivery pump for paint manufacturing includes a pump body 1, one side of the pump body 1 is connected to a liquid inlet pipe 2, an anti-backflow component 3 is arranged inside the pump body 1, the top of the pump body 1 is connected to a liquid discharge pipe 4, a base 5 is fixedly installed at the bottom of the pump body 1, and moving wheels 6 are arranged at the four corners of the base 5.

[0026] The liquid paint enters the pump body 1 through the liquid inlet pipe 2 and is discharged through the discharge pipe 4 to transport the liquid paint. When the pump body 1 is shut down, the anti-backflow component 3 prevents the liquid inside the discharge pipe 4 from being blocked, thereby achieving the effect of preventing the liquid backflow from affecting the normal transportation of the liquid. The pump body 1 is bolted to the base 5 for easy installation and disassembly, and the pump body 1 can be easily moved to a designated location through the moving wheels 6.

[0027] In the specific implementation process, Figure 1 and Figure 2 As shown, a first sealing plate 101 and a second sealing plate 102 are fixedly connected to the inner wall of the pump body 1 , and a liquid inlet hole 103 is opened inside the first sealing plate 101 and the second sealing plate 102 . A liquid discharge hole 104 is opened at the top of the pump body 1 .

[0028] The liquid entering the pump body 1 flows through the liquid inlet holes 103 inside the first sealing plate 101 and the second sealing plate 102 , and enters the liquid discharge pipe 4 through the liquid discharge hole 104 .

[0029] The anti-backflow assembly 3 includes a fixed cylinder 31 arranged on the inner wall of the pump body 1, a spring 32 is fixedly connected to the inside of the fixed cylinder 31, a fixed rod 33 is fixedly connected to the bottom end of the spring 32, a sealing head 34 is fixedly connected to the bottom of the fixed rod 33, a mounting rod 35 is fixedly connected to the outside of the fixed rod 33, and a plurality of sealing columns 36 are fixedly connected to the bottom of the mounting rod 35. The outer sides of the sealing head 34 and the sealing columns 36 are tightly fitted with the inner wall of the liquid inlet hole 103.

[0030] The sealing head 34 and the sealing column 36 seal the liquid inlet hole 103. When the liquid enters the pump body 1, the pressure increases and the sealing head 34 is lifted, so that the fixed rod 33 at the top of the sealing head 34 moves up in the fixed cylinder 31 and squeezes the spring 32. When the fixed rod 33 moves up, it drives the installation rod 35 and the sealing column 36 to move up. At this time, the sealing head 34 and the sealing column 36 are separated from the liquid inlet hole 103, allowing the liquid to circulate normally. After the liquid inlet stops, the pressure disappears, and under the elastic force of the spring 32, the fixed rod 33 returns to its initial position. The sealing head 34 and the sealing column 36 re-enter the liquid inlet hole 103 and seal it, thereby blocking the reflux of liquid, preventing liquid reflux, and avoiding the pressure conflict between reflux and delivery.

[0031] For further reference, Figure 1 and Figure 3 As shown, the four corners of the top of the base 5 are fixedly connected with a fixing plate 7, and the top of the fixing plate 7 is fixedly connected with a fixing column 8.

[0032] Specifically, a lifting seat 9 is provided on the sliding sleeve of the fixed column 8, and a mounting block 10 is fixedly connected to one side of the fixed column 8. A screw 11 is rotatably provided on the inner wall of the mounting block 10. The outer side of the screw 11 is threadedly connected to the inner wall of the lifting seat 9, and the bottom of the screw 11 is rotatably connected to the top of the fixed plate 7.

[0033] Preferably, one side of the lifting seat 9 is connected to the moving wheel 6 via a rotating shaft, and a knob 12 is fixedly connected to the top of the screw rod 11.

[0034] The fixed plate 7 supports and fixes the fixed column 8, and the lifting seat 9 is slidably sleeved on the fixed column 8. The lifting seat 9 supports and fixes the moving wheel 6. After the pump body 1 is moved to the designated location, the screw 11 is rotated by the knob 12. The screw 11 rotates in the fixed plate 7 and the mounting block 10, driving the lifting seat 9 to move upward, so that the moving wheel 6 is away from the ground, ensuring the stability of the pump body 1 during operation and not easy to move.

[0035] The working principle of a liquid delivery pump for coating manufacturing provided by the utility model is as follows:

[0036] When in use, liquid paint enters the pump body 1 through the liquid inlet pipe 2. When the liquid enters the pump body 1, the pressure increases to lift the sealing head 34, causing the fixing rod 33 at the top of the sealing head 34 to move upward in the fixing cylinder 31 and squeeze the spring 32. When the fixing rod 33 moves upward, it drives the installation rod 35 and the sealing column 36 to move upward. At this time, the sealing head 34 and the sealing column 36 are separated from the liquid inlet hole 103, allowing the liquid to circulate normally and enter the discharge pipe 4 through the discharge hole 104 to transport the liquid paint. After the transportation is stopped, the pressure disappears, and the elastic force of the spring 32 causes the fixing rod 33 to return to its initial position, and the sealing head 34 and the sealing column 36 re-enter the liquid inlet hole 103 to seal it, thereby blocking the reflux of liquid, preventing liquid reflux, and avoiding the pressure conflict between reflux and transportation, thereby achieving the effect of preventing liquid reflux from affecting the normal transportation of liquid.

[0037] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
