[0002] Etching is a technique that removes materials by chemical reaction or physical impact. Etching technology can be divided into two categories: wet etching and dry etching.

[0003] During the magnesium alloy etching process, the etching liquid in the liquid tank needs to be stirred to prevent the etching liquid from accumulating. For example, the technical solution disclosed in the magnesium alloy etching plate etching temperature control device disclosed in Chinese utility model patent authorization publication number CN211848146U uses stirring blades to stir the etching liquid in the liquid tank. However, this device still has the following problems: the stirring effect of the stirring blade is limited and cannot effectively mix the upper and lower layers of the etching liquid. Utility Model Content

[0004] Based on this, it is necessary to provide a magnesium alloy etching plate etching temperature control device to address the problems existing in the current etching equipment, so as to solve the problem of poor mixing and stirring effect between the upper and lower layers of etching liquid in the existing etching temperature control device.

[0005] The above purpose is achieved through the following technical solutions:

[0029] like Figures 1-4 As shown, a magnesium alloy etching plate etching temperature control device includes a liquid storage tank 100 and a vertical conveying auger 200. An annular chamber 110 is provided in the liquid storage tank 100. The vertical conveying auger 200 has multiple edge areas close to the annular chamber 110. The vertical conveying auger 200 can rotate around its axis, and multiple vertical conveying auger 200 can rotate around the axis of the annular chamber 110. A liquid outlet pipe 300 is provided in the center of the annular chamber 110, and a guide pipe 210 is provided at the upper part of the vertical conveying auger 200. An elastic cone bucket 310 is provided at the upper end of the liquid outlet pipe 300, and the lower end of the liquid outlet pipe 300 passes through the bottom of the liquid storage tank 100. A number of electric telescopic rods 320 are provided at equal intervals in the circumferential direction of the liquid outlet pipe 300, and the telescopic end of the electric telescopic rod 320 is connected to the lower part of the elastic cone bucket 310.

[0030] It should be added that a liquid inlet pipe 400 is provided at the upper portion of the liquid storage tank 100 , and the liquid inlet pipe 400 is used to transport the etching liquid into the annular chamber 110 .

[0031] Under normal working conditions, the staff rotates the vertical conveying auger 200 around its axis so that the vertical conveying auger 200 lifts the etching liquid from bottom to top. At the same time, multiple vertical conveying augers 200 rotate around the axis of the annular chamber 110, so that the etching liquid in the edge area of ​​the annular chamber 110 is stirred by the vertical conveying auger 200. The etching liquid lifted by the vertical conveying auger 200 to the position of the guide pipe 210 flows into the elastic cone bucket 310. The etching liquid entering the elastic cone bucket 310 is transported outward to the etching equipment through the liquid outlet pipe 300, so that the etching equipment sprays the etching liquid to etch the magnesium alloy.

[0032] In the temporary shutdown state, the vertical conveying auger 200 stops rotating around its axis. At the same time, the multiple vertical conveying auger 200 also stop rotating around the axis of the annular chamber 110.

[0033] After the temporary shutdown is restored, the staff first starts the electric telescopic rod 320, so that the telescopic end of the electric telescopic rod 320 contracts and drives the lower part of the elastic cone bucket 310 to move downward, so that the elastic cone bucket 310 switches from the state of opening upward to the state of opening downward, and then makes the vertical conveying auger 200 continue to rotate around its axis. At the same time, the multiple vertical conveying augers 200 also continue to rotate around the axis of the annular chamber 110. At this time, the vertical conveying auger 200 continues to lift the etching liquid from bottom to top. At the same time, the multiple vertical conveying augers 200 also continue to stir the etching liquid. At this time, the etching liquid flowing out of the guide pipe 210 flows along the elastic cone bucket 310. The inclined surface of the bucket 310 flows downward into the annular chamber 110. During this process, the etching liquid inside the annular chamber 110 is continuously stirred and mixed from bottom to top by the vertical conveying auger 200, so that the upper and lower layers of the etching liquid inside the annular chamber 110 are gradually mixed evenly. After the etching liquid inside the annular chamber 110 is evenly mixed, the telescopic end of the electric telescopic rod 320 is extended outward, so that the elastic cone bucket 310 switches from opening downward to opening upward. At this time, the etching liquid flowing out of the guide pipe 210 flows into the elastic cone bucket 310 and is transported outward to the etching equipment through the liquid outlet pipe 300 to continue etching the magnesium alloy plate.

[0034] It should also be noted that when the etching duration is long, in order to prevent the etching liquid from stratifying, the staff can temporarily stop the machine for a few minutes, so that the telescopic end of the electric telescopic rod 320 drives the elastic cone bucket 310 to move downward, so that the elastic cone bucket 310 is in a downward opening state. At this time, the etching liquid is vertically lifted and mixed by the vertical conveying auger 200 to promote the mixing between the upper and lower layers of the etching liquid, and then it can be switched to the normal working state. In this way, the etching liquid can be made more uniform when the etching time is long.

[0035] In a further embodiment, Figure 4 As shown, the vertical conveying auger 200 includes an auger shaft 220 and an auger outer cylinder 230. The auger shaft 220 is coaxially connected to the auger outer cylinder 230. An upper guide groove 111 is provided on the upper part of the peripheral wall of the annular chamber 110. An upper guide ring 231 is rotatably connected in the upper guide groove 111. The upper guide ring 231 is fixedly connected to the auger outer cylinder 230. A lower guide groove 112 is provided on the lower part of the peripheral wall of the annular chamber 110. A lower guide ring 232 is rotatably connected in the lower guide groove 112. The lower guide ring 232 is fixedly connected to the auger outer cylinder 230.

[0036] The cooperation between the upper guide groove 111 and the upper guide ring 231 and the cooperation between the lower guide groove 112 and the lower guide ring 232 is used to guide the rotation of the auger outer cylinder 230 around the axis of the annular chamber 110 and to support the auger outer cylinder 230 .

[0037] In a further embodiment, Figure 3 As shown, a conical material guide plate 330 is provided on the outer peripheral wall of the liquid outlet pipe 300 and below the electric telescopic rod 320 , and the conical material guide plate 330 is inclined downward.

[0038] A conical guide plate 330 is provided to guide the etching liquid in the lower part of the annular chamber 110 so that the etching liquid in the annular chamber 110 can flow from the center to the surroundings.

[0039] In a further embodiment, Figure 3 and Figure 4 As shown, a drive motor 116 is provided on the top of the liquid storage tank 100, and the output end of the drive motor 116 is fixedly connected to a drive gear 117, which is engaged with the upper rotating ring gear 115. The lower part of the annular chamber 110 is coaxially connected to the lower rotating ring 114, and the lower end of the auger shaft 220 of the vertical conveying auger 200 is rotatably connected to the lower rotating ring 114. The upper part of the annular chamber 110 is coaxially connected to the upper rotating ring gear 115, and the upper rotating ring gear 115 can rotate around its axis. The upper part of the annular chamber 110 is coaxially provided with a guide ring gear 113, and the upper end of the auger shaft 220 of the vertical conveying auger 200 is fixedly connected to a planetary gear 240, which is engaged with the guide ring gear 113.

[0040] When in use, the drive motor 116 is started, and the output shaft of the drive motor 116 drives the drive gear 117 to rotate, and the drive gear 117 drives the upper rotating ring gear 115 to rotate. The rotation of the upper rotating ring gear 115 drives the auger shaft 220 to rotate synchronously around the axis of the annular chamber 110. Since the planetary gear 240 is engaged with the guide gear ring 113, the auger shaft 220 rotates synchronously around the axis of the annular chamber 110 while also rotating around its own axis, so that the auger outer cylinder 230 stirs the etching liquid in the annular chamber 110 while the auger shaft 220 also lifts the etching liquid from bottom to top.

[0041] In a further embodiment, a heating wire is provided in the inner wall interlayer of the liquid storage tank 100 , and the heating wire is used to heat the etching liquid in the annular chamber 110 .

[0042] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
