[0002] Aluminum alloy strips are mainly used for processing cable shielding layers. Aluminum alloy strips need to be pre-electroplated with an anti-corrosion conductive layer. When electroplating, aluminum alloy strips need to be electroplated with electrolytic agents to improve the corrosion resistance and conductivity of the aluminum alloy strips.

[0003] In the related technology, the supply device includes a shell and an electrolytic cell. The shell is provided with a first connecting pipe and a second connecting pipe. The first connecting pipe and the second connecting pipe are both connected to the electrolytic cell. The first connecting pipe drives the liquid to move from the shell to the electrolytic cell, and the second connecting pipe drives the liquid to move from the electrolytic cell to the shell.

[0004] After the aluminum alloy strip has been electrolyzed for a long time, some impurities may exist in the reagent. These impurities will affect the electroplating of the aluminum alloy strip by the reagent. Therefore, the reagent needs to be replaced, so that the reagent cannot be used for a long time. Summary of the invention

[0005] In order to improve the problem of some impurities in the reagent, the present application provides an automatic reagent supply device for aluminum alloy strip coating.

[0006] The present application provides an automatic supply device for coating agents for aluminum alloy strips, which adopts the following technical solutions:

[0008] By adopting the above technical solution, the reagent is extracted through the transport pipeline, and the reagent is moved from the shell to the filter. The filter filters the reagent, so that the impurity content in the reagent is reduced to a level that does not affect the electroplating of the aluminum alloy strip by the reagent, thereby allowing the reagent to be recycled, increasing the utilization rate of the reagent, and allowing the aluminum alloy strip to be better coated.

[0014] By adopting the above technical solution, when the fixed plate is placed in the accommodating groove, the stop spring drives the stop bar to move, and the stop bar is inserted into the limiting hole, so that the stop bar limits the fixed plate. At this time, the limiting bar moves in the limiting hole until the limiting bar is inserted into the limiting groove, so that the limiting bar is inserted into the limiting groove, so that the fixed plate can be fixed and the observation plate can be fixed at the same time. When the staff locks the observation plate, the fixed plate is locked synchronously, so that the staff can avoid ignoring whether the fixed plate is fixed when detecting the medicine, so that the fixed plate can be more stably fixed on the shell.

[0015] Optionally, a receiving groove is provided on the fixed plate, a handle is slidably connected to the receiving groove, a limiting plate is provided on the limiting bar, and the limiting plate is used to block the opening of the receiving groove; when the handle protrudes from the receiving groove, the limiting bar is separated from the limiting groove.

[0016] By adopting the above technical solution, when the limit bar is inserted into the limit groove, the limit plate is arranged on the limit bar, so that the limit plate can block the opening of the receiving groove, so that the handle can be stably located in the receiving groove. At this time, the staff can know whether the fixing plate is fixed by observing the handle, thereby avoiding the situation where the fixing plate is not fixed; at the same time, the limit plate blocks the opening of the receiving groove, so that the handle can be stably located in the receiving groove, avoiding erosion and pollution of the handle by the external environment, reducing the possibility of rusting of the handle, and extending the service life of the handle.

[0021] Optionally, an observation block is provided on the observation plate, and the observation block is located on a side of the fixing bar away from the fixing spring. The observation block is located on a side of the fixing bar away from the fixing spring.

[0022] By adopting the above technical solution, the observation block is located on the side of the fixed bar away from the fixed spring, so that the fixed bar can drive the observation block to move, and the observation block drives the observation plate to rotate, so that one side of the observation plate is tilted to facilitate the staff to rotate the observation plate; at the same time, when the staff blocks the perforation of the observation plate, the observation block drives the fixed bar to move, so that the fixed bar does not block the limit hole.

[0023] Optionally, a first magnet is provided on the fixing bar, a blocking bar for blocking the groove is rotatably connected to the fixing plate, a second magnet is provided on the blocking bar, and the first magnet repels the second magnet; when the fixing bar blocks the limiting hole, the blocking bar does not block the opening of the groove.

[0024] By adopting the above technical solution, when the fixed bar blocks the limiting hole, the first magnet repels the second magnet, so that the blocking bar can move. At this time, the blocking bar does not block the opening of the groove, so that the staff can know whether the limiting bar has moved into place by observing whether one side of the blocking bar is tilted, thereby avoiding the staff from moving the limiting bar excessively and eliminating the need for the staff to confirm the movement of the limiting bar.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The reagent is extracted through a transport pipeline and moved from the shell to the filter. The filter filters the reagent to reduce the proportion of impurities in the reagent to a level that does not affect the electroplating of the aluminum alloy strip by the reagent, thereby allowing the reagent to be recycled, increasing the utilization rate of the reagent and allowing the aluminum alloy strip to be better coated.
