[0045] Please see Figure 1 A coating liquid delivery device for a coating machine includes a tank 1, a suction pipe 2 extending from the tank 1, a pump 3 connected to the suction pipe 2, and a coating machine 6.

[0046] It also includes a feed pipe 4 connected to the outlet of the pump 3;

[0047] It also includes a stirring and feeding component 5, which is designed between the tank 1 and the coating machine 6 to achieve stirring and feeding, solve the problem of coating liquid sedimentation, facilitate coating process and improve coating quality;

[0048] Please see Figures 2 to 4 The mixing and feeding assembly 5 includes a support 51, which is connected to the base of the coating machine 6;

[0049] A connecting frame 511 extends from the front of the bracket 51. A feeding cylinder 54 is installed below the connecting frame 511. The top of the feeding cylinder 54 has a cylinder cover. The cylinder cover is provided with a feeding port. A feeding hopper 52 is provided at the feeding port. The other end of the feeding pipe 4 is connected to the feeding hopper 52.

[0050] The lower ends of both the feeding component 55 and the stirring component 56 extend into the feeding cylinder 54;

[0051] The bottom of the feeding cylinder 54 is provided with a feeding pipe 53, and the inner hole of the feeding pipe 53 communicates with the inside of the feeding cylinder 54.

[0052] The bottom of the injection pipe 53 is connected to the liquid storage tank of the coating machine 6, for reference. Figure 1 .

[0053] Please see Figures 5 to 7 This is a structure of a feeding component 55, which includes a feeding motor 551 disposed on the top of the connecting frame 511. The feeding motor 551 is connected to a first shaft 552 via a coupling 556, and the lower end of the first shaft 552 extends into the feeding cylinder 54.

[0054] A bushing 555 is provided at the junction of the first shaft 552 and the feed cylinder 54 (i.e., the cover of the feed cylinder 54). The outer ring of the first bearing 554 is interference-fitted with the bushing 555, and the first shaft 552 is interference-fitted with the inner ring of the first bearing 554.

[0055] The outer side of the bushing 555 is fixedly connected to the cover of the feed cylinder 54;

[0056] The lower end of the first shaft 552 is provided with a spiral conveying rod 553, and the lower end of the spiral conveying rod 553 extends into the inner hole of the injection tube 53.

[0057] The material feeding motor 551 rotates, driving the first shaft 552 to rotate, and the screw conveyor 553 is driven to rotate to discharge the coating liquid, thus realizing material feeding.

[0058] Please see Figure 5, Figure 8 and Figure 9 This is a structure of a stirring component 56, which includes a stirring motor 561 disposed on the top of the connecting frame 551. The main shaft of the stirring motor 561 is connected to a second shaft 562, and a drive wheel 563 is installed at the lower end of the second shaft 562.

[0059] The inner ring of the second bearing 567 is interference-fitted on the shaft body of the first shaft 552, and the second bearing 567 is located below the first bearing 554.

[0060] The outer ring of the second bearing 567 is interference-fitted to the rotating sleeve 568. The top of the rotating sleeve 568 is connected to the driven wheel 568. The driven wheel 569 is connected to the driving wheel 563 through the transmission belt 564.

[0061] A hoop 565 is fitted on the outer circumferential surface of the rotating sleeve 568, and a stirring blade 566 is installed on each side of the hoop 565.

[0062] Please see Figure 8 For ease of installation and processing, the hoop 565 consists of two semi-circular hoop rings connected together by threaded connectors.

[0063] The stirring motor 561 rotates, driving the rotating sleeve 568 to rotate, which in turn drives the stirring blade 566 to stir. Due to the setting of the second bearing 567, the rotation of the rotating sleeve 568 does not interfere with the rotation of the first shaft 552.

[0064] It should be noted that after the coating liquid is drawn out by pump 3, it enters the feeding cylinder 54. Due to the gap between the screw conveyor 553 and the injection pipe 53, and because the coating liquid is relatively concentrated, it will not drip immediately. The stirring component 56 then rotates to stir the liquid. Just before it is about to drip, the feeding component 55 operates to discharge the liquid. To prolong the dripping time of the coating liquid, the feeding cylinder 54 is inclined (see reference). Figure 1 ).

[0065] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
