[0029] Example 1

[0030] This embodiment provides a quantitative feeding device for leather finishing agent production, such as Figure 1As shown, it includes a grid frame 1, a coating agent raw material box 2 and a water tank 3 are fixedly installed at the grid opening of the grid frame 1, and the water tank 3 is located below the coating agent raw material box 2. A plurality of coating agent raw material boxes 2 are provided, and different types of raw materials are contained in the plurality of coating agent raw material boxes 2. A stirring device 6 is provided inside the mixing tank 5, and a supporting base is fixedly installed at the bottom of the mixing tank 5. The stirring device 6 stirs the raw materials entering the mixing tank 5 to accelerate the mixing efficiency of the raw materials. The coating agent needs to use water as a solvent, so water needs to be used quantitatively.

[0031] like Figure 2 and 3 As shown, the side of the finishing agent raw material box 2 is connected to a residual processing assembly 4, and the residual processing assembly 4 includes a raw material adding pipe 41, a raw material discharging pipe 42, a flushing water pipe 43 and a first valve 44. The end of the raw material adding pipe 41 is connected to the flushing water pipe 43, and the connection between the raw material adding pipe 41 and the flushing water pipe 43 is connected to the raw material discharging pipe 42. The side of each finishing agent raw material box 2 is connected to the raw material discharging pipe 42, and the end of the raw material adding pipe 41 is connected to the mixing tank 5.

[0032] like Figure 3 As shown, a first valve 44 is fixedly installed at the end of the raw material discharge pipe 42, and the raw materials in the coating agent raw material box 2 enter the interior of the mixing tank 5 along the raw material discharge pipe 42 and the raw material addition pipe 41 for addition. The first valve 44 controls the flow of the raw materials in the raw material discharge pipe 42, and controls the flow rate of the raw materials by its opening time, thereby realizing quantitative addition.

[0033] The end of the flushing water pipe 43 is connected to the water tank 3, and a second valve 45 is fixedly installed in the middle of the flushing water pipe 43, and water is quantitatively added through the second valve 45. First, the first valve 44 is opened to add raw materials. After the quantitative raw materials are released, the first valve 44 is closed, and the second valve 45 is opened to allow water to enter the flushing water pipe 43, so that the water flushes the residual raw materials inside the raw material adding pipe 41, so that all the raw materials enter the mixing tank 5, avoiding the waste of raw materials and avoiding inaccurate raw material addition.

[0034] like Figure 3 As shown, the end of the flushing water pipe 43 connected to the raw material adding pipe 41 is tilted, and the end of the flushing water pipe 43 connected to the water tank 3 is tilted upward. The flushing water pipe 43 is tilted to prevent the raw materials flowing out of the flushing water pipe 43 from flowing back into the flushing water pipe 43, and the second valve 45 further prevents the raw materials from flowing into the water tank 3 from the flushing water pipe 43.

[0035] In this embodiment, the first valve 44 is first opened to allow the raw materials in the finishing agent raw material box 2 to enter the interior of the mixing tank 5 along the raw material discharge pipe 42 and the raw material addition pipe 41, and the raw materials are quantitatively added using the first valve 44. Subsequently, the first valve 44 is closed, and then the second valve 45 is opened to allow the water in the water tank 3 to enter the mixing tank 5 along the flushing water pipe 43 and the raw material addition pipe 41 to flush the residual raw materials in the raw material addition pipe 41, so that all the raw materials enter the interior of the mixing tank 5, thereby avoiding waste of raw materials and preventing inaccurate raw material addition from affecting the quality of the leather finishing agent.

[0036] Example 2

[0037] Based on Example 1, this example proposes a quantitative feeding device for leather finishing agent production, such as Figure 4 As shown, a swirl assembly 7 is provided inside the water tank 3, and the swirl assembly 7 includes a water pump 71 and a swirl tube 73. The water pump 71 is fixedly installed inside the water tank 3, and the water outlet of the water pump 71 is connected to the swirl tube 73. The end of the swirl tube 73 is connected to the flushing water pipe 43. The swirl tube 73 adopts a spiral structure, and water flows from the swirl tube 73 into the second valve 45.

[0038] Since there is a certain buffer margin in the pipeline to avoid the pipeline from being broken due to a surge in water volume, the water in the pipeline will not flow fully under normal circumstances. In order for the inner wall of the raw material addition pipe 41 to be completely contacted by water, the water inside the water tank 3 is pumped into the vortex tube 73 through the water pump 71, and the water flows along the vortex tube 73. After the water flows out from the end of the vortex tube 73, the water will spirally flow along the inner wall of the flushing water pipe 43, so that the water spirally flows on the inner wall of the raw material addition pipe 41.

[0039] like Figure 4 As shown, a plurality of equally spaced support rings 72 are fixedly installed inside the water tank 3, and a water pump 71 is fixedly installed inside the water tank 3 through the support rings 72. The support rings 72 support the water pump 71 to fix its position.

[0040] In this embodiment, through the spiral structure design of the vortex tube 73, water flows in a spiral along the vortex tube 73, so that after the water enters the flushing water pipe 43 and the raw material addition tube 41, the water flows in a spiral shape, so that the inner wall of the raw material addition tube 41 is completely contacted by water, avoiding the existence of parts inside the raw material addition tube 41 that are not contacted by water, and allowing the residual raw materials in the raw material addition tube 41 to be completely flushed into the interior of the mixing tank 5.

[0041] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
