[0032] Reference Figure 1 The present application discloses a liquid inlet box, which includes a box body 100 and at least one slow flow plate 120. The box body 100 is provided with at least one liquid inlet channel 110; the slow flow plate 120 is arranged in the liquid inlet channel 110, and at least one protrusion 130 is provided on the surface of the slow flow plate 120.

[0033] Specifically, the liquid inlet channel 110 has an inlet 111 and an outlet 112. Liquid can flow into the liquid inlet channel 110 from the inlet 111 and flow out through the outlet 112. The slow flow plate 120 is arranged between the inlet 111 and the outlet 112 of the liquid inlet channel 110. When the liquid passes through the liquid inlet channel 110, the slow flow plate 120 and the protrusion 130 arranged on the surface of the slow flow plate 120 can block the liquid, thereby guiding and slowing down the flow of the liquid, effectively reducing the impact force of the liquid, so that the liquid can smoothly enter the machine after passing through the liquid inlet channel 110, reducing the impact on the equipment and the generation of water ripples, and improving product quality. In fact, two or more liquid inlet channels 110 may be provided on the box body 100, and each liquid inlet channel 110 may be provided with a slow flow plate 120, or at least one liquid inlet channel 110 may be provided with a slow flow plate 120, and multiple upper liquid pipes of the foil production machine may be connected to the liquid inlet channels 110 one by one, respectively, or a single upper liquid pipe of an external foil production machine may be connected to the water inlet 111 of any liquid inlet channel 110, or connected to the water inlets 111 of all liquid inlet channels 110 at the same time.

[0034] Furthermore, the liquid inlet channel 110 has a water inlet 111 and a water outlet 112, and the liquid inlet channel 110 is provided with a first inner wall 113 and a second inner wall 114, the first inner wall 113 and the second inner wall 114 are arranged opposite to each other, and both extend from the water inlet 111 to the water outlet 112, and the slow flow plate 120 is located between the first inner wall 113 and the second inner wall 114, and the slow flow plate 120 is inclined relative to at least one of the first inner wall 113 and the second inner wall 114.

[0035] Specifically, the slow flow plate 120 is located between the first inner wall 113 and the second inner wall 114, and the slow flow plate 120 is inclined relative to at least one of the first inner wall 113 and the second inner wall 114. The slow flow plate 120 inclined relative to the first inner wall 113 and / or the second inner wall 114 can guide and slow down the flow of the liquid, and reduce the direct impact of the liquid passing through the liquid inlet channel 110 on the surface of the slow flow plate 120, thereby improving the installation strength and service life of the slow flow plate 120. It should be noted that the first inner wall 113 and the second inner wall 114 can be parallel to each other, or there can be an angle between the first inner wall 113 and the second inner wall 114, or the first inner wall 113 and the second inner wall 114 are symmetrical to each other. Figure 2 In this embodiment, the first inner wall 113 and the second inner wall 114 are parallel to each other, and the slow flow plate 120 is inclined relative to the first inner wall 113 and the second inner wall 114. In addition, in some other embodiments, the slow flow plate 120 can also be perpendicular to the first inner wall 113 and the second inner wall 114.

[0036] Furthermore, one end of the slow flow plate 120 is connected to the first inner wall 113, and the other end of the slow flow plate 120 extends obliquely in a direction away from the first inner wall 113 and is spaced apart from the second inner wall 114; or one end of the slow flow plate 120 is connected to the second inner wall 114, and the other end of the slow flow plate 120 extends obliquely in a direction away from the second inner wall 114 and is spaced apart from the first inner wall 113.

[0037] Specifically, the slow flow plate 120 disposed on the first inner wall 113 is spaced apart from the second inner wall 114, while the slow flow plate 120 disposed on the second inner wall 114 is spaced apart from the first inner wall 113, and the slow flow plate 120 plays the role of slowing down the flow and guiding the liquid, so as to facilitate the liquid to flow along the liquid inlet channel 110. In fact, at least one slow flow plate 120 can be disposed on the first inner wall 113, or on the second inner wall 114, or the slow flow plates 120 are evenly distributed on the first inner wall 113 and the second inner wall 114.

[0038] In this embodiment, the slow flow plate 120 is inclined toward the water inlet 111 .

[0039] Specifically, one end of the slow flow plate 120 is connected to the liquid inlet channel 110, and the other end of the slow flow plate 120 extends obliquely toward the direction close to the water inlet 111. If the slow flow plate 120 is set on the first inner wall 113, the angle between the slow flow plate 120 and the first inner wall 113 is an acute angle. If the slow flow plate 120 is set on the second inner wall 114, the angle between the slow flow plate 120 and the second inner wall 114 is an acute angle, which reduces the impact of the liquid on the slow flow plate 120. Figure 1 and Figure 2 As shown, all the slow flow plates 120 are inclined toward the water inlet 111. In some embodiments, all the slow flow plates 120 may extend and incline toward the water outlet 112. In addition, some of the slow flow plates 120 may be inclined toward the water inlet 111, and another part of the slow flow plates 120 may be inclined toward the water outlet 112. Specifically, the slow flow plates 120 connected to the first inner wall 113 may be inclined toward the water inlet 111, and the slow flow plates 120 connected to the second inner wall 114 may be inclined toward the water outlet 112.

[0040] Furthermore, the inclination angle of the slow flow plate 120 relative to the first inner wall 113 or the second inner wall 114 is 25° to 50°.

[0041] Specifically, the inclination angle of the slow flow plate 120 relative to the first inner wall 113 or the second inner wall 114 is greater than 25°, so that the slow flow plate 120 can achieve blocking and buffering of the liquid entering the liquid inlet channel 110, thereby ensuring the slow flow efficiency, and the inclination angle of the slow flow plate 120 relative to the first inner wall 113 or the second inner wall 114 is less than 50°, thereby reducing the impact of the water flow on the slow flow plate 120, improving the connection strength of the slow flow plate 120 connected to the liquid inlet channel 110, and improving the service life of the slow flow plate 120. In the present application, the inclination angle of the slow flow plate 120 relative to the first inner wall 113 or the second inner wall 114 is 25° to 50°, so that the impact of the water flow can be reduced while achieving liquid buffering, such as Figure 2 As shown, the angle between the slow flow plate 120 connected to the first inner wall 113 and the first inner wall 113 is a first inclination angle α, and the first inclination angle α is 25° to 50°. The angle between the slow flow plate 120 connected to the second inner wall 114 and the second inner wall 114 is a second inclination angle β, and the second inclination angle β is 25° to 50°. In fact, the angle between the slow flow plate 120 and the first inner wall 113 or the second inner wall 114 can be 30°, 40°, 50°, etc.

[0042] In some embodiments, the slow flow plate 120 has a first surface 210 and a second surface 220 facing each other, the first surface 210 faces the water inlet 111, and the second surface 220 faces the water outlet 112, and at least one protrusion 130 is respectively provided on the first surface 210 and the second surface 220. Specifically, the protrusion 130 on the first surface 210 can stabilize the liquid flow entering the liquid inlet channel 110 from the water inlet 111, reduce the splashing of the liquid flow, reduce the impact force of the liquid flow, and play a role in controlling and guiding the liquid flow. In addition, the protrusion 130 on the first surface 210 can cause the liquid contacting the first surface 210 of the slow flow plate 120 to form a reflux to avoid liquid accumulation, and the protrusion 130 on the second surface 220 can control and guide the liquid flow to flow in the direction of the water outlet 112, further reduce the impact force of the liquid flow, and effectively improve the slow flow effect of the liquid inlet box.

[0043] In addition, the bump 130 can be only arranged on the first surface 210 to reduce liquid splashing, or only arranged on the second surface 220 to guide the liquid flow, or arranged on other sides of the slow flow plate 120 to cooperate with the slow flow plate 120 to achieve a slow flow effect.

[0044] In some embodiments, two protrusions 130 are distributed on the same surface of the slow flow plate 120 , and the two protrusions 130 are arranged at intervals along the extension direction of the slow flow plate 120 .

[0045] Specifically, at least two protrusions 130 are arranged on the same surface of the slow flow plate 120. When the liquid flows through the liquid inlet channel 110, the liquid flow direction can conform to the extension direction of the slow flow plate 120 or be opposite to the extension direction of the slow flow plate 120, so that the liquid flow can be affected by at least two protrusions 130 in turn, further effectively achieving the slow flow effect on the liquid. In some other embodiments, only one protrusion 130 can be arranged on the same surface of the slow flow plate 120, or multiple protrusions 130 can be arranged on the same surface of the slow flow plate 120 along the extension direction of the slow flow plate 120. The number of protrusions 130 is related to the actual design extension length of the slow flow plate 120.

[0046] Reference Figure 2 Three slow flow plates 120 are arranged in the same liquid inlet channel 110 , and the three slow flow plates 120 are arranged in a staggered manner along the extension direction of the liquid inlet channel 110 .

[0047] Specifically, three slow flow plates 120 are arranged in a staggered manner along the extension direction of the liquid inlet channel 110, and a plurality of slow flow plates 120 are arranged in the liquid inlet channel 110 to further improve the slow flow effect, and the intervals between the three slow flow plates 120 can form a flow channel for the liquid to flow, which can further guide the liquid flow, reduce the impact of the liquid flow, and make the liquid flow smoothly. In addition, in some other embodiments, one, two, or more than three slow flow plates 120 can be arranged in the same liquid inlet channel 110 to achieve a slow flow effect on the liquid passing through the liquid inlet channel 110. Furthermore, the two slow flow plates 120 respectively arranged on the inner walls of the two opposite sides of the liquid inlet channel 110 may be relatively extended, wherein when the two slow flow plates 120 are relatively arranged, the two slow flow plates 120 may extend opposite to each other and be on the same plane, the two slow flow plates 120 may be inclined relative to the first inner wall 113 or the second inner wall 114 of the liquid inlet channel 110, and the two may be symmetrical to each other, one slow flow plate 120 may be inclined toward the water inlet 111, and the other slow flow plate 120 may be inclined toward the water outlet 112, and the two may be parallel to each other. In addition, two adjacent slow flow plates 120 may also be staggered and extended, and this embodiment does not limit the specific arrangement of the slow flow plates 120.

[0048] In some specific embodiments, the liquid inlet channel 110 extends in the up-down direction, the lower end opening of the liquid inlet channel 110 is a water inlet 111 , and the upper end opening of the liquid inlet channel 110 is a water outlet 112 .

[0049] Specifically, by inletting liquid through the bottom of the liquid inlet channel 110, the liquid can be effectively blocked and buffered by the slow flow plate 120 and the protrusion 130. The bottom liquid inlet can control the flow rate and speed of the liquid flow, so that the liquid can smoothly and evenly enter the subsequent machine, so that the liquid flow can be effectively discharged.

[0050] In the present embodiment, the three slow flow plates 120 are staggered and spaced from bottom to top along the extension direction of the liquid inlet channel 110. One end of the slow flow plate 120 located in the middle is arranged on the first inner wall 113, and the other extension end is spaced from the second inner wall 114. One end of the two slow flow plates 120 located on the two side edges is arranged on the second inner wall 114, and the other extension end is spaced from the first inner wall 113. The extension ends of the slow flow plates 120 are all inclined downward and extended in the direction close to the bottom water inlet 111, which effectively reduces the impact force of the liquid flow, so that the inner wall of the liquid inlet channel 110 can withstand part of the impact, improves the service life of the slow flow plates 120, and facilitates workers to operate and maintain. The slow flow plates 120 face the first surface 21 of the bottom water inlet 111. 0 is provided with two protrusions 130, so that the liquid can flow back in the groove body surrounded by the protrusions 130 on the first surface 210 and the slow flow plate 120, so as to block the impact of the liquid flow and avoid liquid accumulation. The two protrusions 130 on the first surface 210 are arranged at intervals along the extension direction of the slow flow plate 120, and the slow flow plate 120 is provided with two protrusions 130 on the second surface 220 facing the top water outlet 112. The two protrusions 130 on the second surface 220 are arranged at intervals along the extension direction of the slow flow plate 120. The liquid passes through the liquid inlet channel 110 from bottom to top. When the liquid submerges the protrusions 130 on the second surface 220, the protrusions 130 on the second surface 220 can effectively support and guide the liquid flow to flow upward, so as to further block the impact of the liquid.

[0051] Reference Figure 3 A plurality of liquid inlet channels 110 are provided, and partitions 310 are provided between adjacent liquid inlet channels 110 to separate adjacent liquid inlet channels 110 .

[0052] Specifically, there are multiple inlet channels 110, and the inlet channels 110 are separated by partitions 310 to improve the slow flow efficiency. In this embodiment, the multiple inlet channels 110 can be arranged in sequence. In fact, the multiple inlet channels 110 can also be arranged in a matrix or irregularly.

[0053] like Figure 4 As shown, in this embodiment, the liquid inlet channel 110 also has a third inner wall 410 and a fourth inner wall 420 relative to each other, the flow control plate 120 is connected between the third inner wall 410 and the fourth inner wall 420, one end of the protrusion 130 extends to the third inner wall 410, and the other end of the protrusion 130 extends to the fourth inner wall 420.

[0054] Specifically, the slow flow plate 120 is connected between the third inner wall 410 and the fourth inner wall 420, and the protrusion 130 is set on the end surface of the slow flow plate 120, and crosses the third inner wall 410 and the fourth inner wall 420 to increase the contact area with the liquid flow and further improve the slow flow effect. In fact, one end of the slow flow plate 120 is connected to the first inner wall 113 or the second inner wall 114, and the other extended end extends toward the second inner wall 114 or the first inner wall 113. The two sides of the slow flow plate 120 parallel to its extension direction are connected to the third inner wall 410 and the fourth inner wall 420, thereby increasing the coverage area of ​​the slow flow plate 120 on the liquid inlet channel 110 and improving the slow flow effect.

[0055] In this embodiment, the cross section of the liquid inlet channel 110 is square, the first inner wall 113, the third inner wall 410, the second inner wall 114 and the fourth inner wall 420 are connected in sequence and enclosed in a closed channel shape, the three sides of the slow flow plate 120 are respectively connected to the three inner walls adjacent in sequence, and the other side of the slow flow plate 120 is spaced and opposite to the first inner wall 113 or the second inner wall 114, so as to improve the connection strength of the slow flow plate 120, increase the contact area with the liquid flow, and further improve the slow flow effect. At the same time, one side of the slow flow plate 120 is spaced from the inner wall of one side of the liquid inlet channel 110 to ensure that the liquid flow can pass through the slow flow plate 120 and output the water outlet 112. In fact, the cross section of the liquid inlet channel 110 can also be circular, elliptical, polygonal or other irregular shapes, the first inner wall 113 and the second inner wall 114 are opposite inner wall positions on both sides, and the third inner wall 410 and the fourth inner wall 420 are opposite inner wall positions on both sides, which can actually be a curved surface or a plane structure.

[0056] Furthermore, the slow flow plate 120 is a titanium plate.

[0057] Specifically, the slow flow plate 120 is a titanium plate, which has better strength and corrosion resistance, and is lighter than stainless steel. In fact, the bump 130, the slow flow plate 120 and the box 100 can also be made of titanium as a whole, which improves strength and corrosion resistance and reduces weight.

[0058] Reference Figure 5 The present application also includes a foil machine 510, which includes the above-mentioned liquid inlet box 520. The foil machine 510 is a key device for preparing copper foil by chemical electrolysis. The foil machine 510 of the present application includes a machine platform, an upper liquid pipeline, a cathode roller and an anode plate. The cathode roller and the anode plate are arranged inside the machine platform, wherein the anode plate is connected to the positive pole of the power supply and the upper liquid pipeline, and the cathode roller is connected to the negative pole of the power supply. When the copper sulfate electrolytic liquid enters the anode plate through the upper liquid pipeline, an electric field is formed between the positive and negative electrodes. Under the action of the electric field, copper ions migrate from the anode to the surface of the cathode roller, where a reduction reaction occurs and is deposited into a thin film.

[0059] In this embodiment, the liquid inlet box 520 is arranged on the upper liquid pipeline, and the upper liquid pipeline can be interconnected with the liquid inlet channel 110 in the liquid inlet box 520. When the foil machine 510 is loading liquid, the liquid is first passed into the liquid inlet box 520, and the liquid is buffered after passing through the slow flow plate 120 and the bump 130 inside the liquid inlet box 520, which effectively reduces the impact force of the liquid, reduces the impact damage to the anode plate and cathode roller inside the machine of the foil machine 510, and reduces the generation of water ripples, thereby improving product quality. In actual connection, the liquid inlet box 520 can be arranged on the upper liquid pipeline of the foil machine 510, so that the upper liquid pipeline can be interconnected with at least one liquid inlet channel 110 in the liquid inlet box 520.
