The copper clad laminate industry is one of the core materials of various computers, mobile phones, communication equipment, household appliances, new energy vehicles and other devices at present, and the copper foil is one of the core materials of the copper clad laminate and is also one of the core materials of the lithium battery. With the rapid development of the electronic information industry and the new energy automobile industry, the demand of various types of copper foils is increasing, and particularly the demand of high-end high-performance copper foils is increasing. The copper foil with extremely low roughness in the copper foil is particularly pursued in the communication industry and the new energy industry due to excellent electrical characteristics.

The utility model also provides an electrolysis system, including foretell powder measurement feeding device, relevant technical characteristics are as before, and here is no longer repeated. The copper foil usually needs to use additives during electrolytic production, the simplest electrolytic copper foil production in the past only needs to use proteins such as gelatin, and the use amount is very small, so that the method is simple and convenient. Can become very troublesome when needing to use extensive powdered additive in case, not only weigh and need many people to cooperate, and dust pollution endangers personnel health, and manual weighing still probably appears the mistake and influences product quality, can cause great loss even.

The overall construction of the device is shown in figure 3. The device mainly comprises the following three parts: the device comprises a powder metering and feeding assembly 100 for metering and feeding the additive, a dissolving assembly 200 for dissolving the fed additive by water, and a control module 300 for electric driving and controlling related to the device. The following describes each constituent element and operation state in the overall schematic diagram of the apparatus shown in fig. 3.

First, for the sake of convenience in describing the configuration and operation of the powder measuring unit, a cross-sectional view (fig. 1) and a perspective view (fig. 2) of the communication relation of the unit are drawn, and fig. 1 and 2 will be described below.

The powder metering and dosing assembly 100 comprises 1 inlet shutter plate with a dosing inlet 102 and 1 outlet shutter plate with an outlet 104, between which two cylindrical metering chambers 107, 108 are located. The upper measuring container 105 and the lower measuring container 106 rotate around a rotation shaft 109. The upper and lower 2 sets of cylindrical metering chamber portions are of a fitting type structure and together form a first metering chamber 107 and a second metering chamber 108. The centers of the cylinders of the first and second metering chambers 107, 108 are located on a straight line passing through the centers of rotation of the upper and lower shutter plates 101, 103. The distance from the center of the cylinder of the metering chamber to the rotation center of the upper and lower shutter plates is equal, i.e., in fig. 2, a and B are equal.

The metering of the powder metering assembly and the action of how it is dosed to the additive tank will now be described. When the opening positions of the inlet 102 of the inlet shutter 101 and the first metering chamber 107 or the second metering chamber 108 are coincident with each other, the additive 110 is filled into the first metering chamber 107 from the additive storage tank 111 through the inlet of the inlet shutter 101, as shown in the figure.

The term "the opening positions coincide" as used herein means that the centers of the inlet 102, the outlet 104, the first measuring chamber 107, and the second measuring chamber 108 coincide with each other when the inlet and the measuring chambers or the outlet and the measuring chambers are all true circles. For the convenience of charging or discharging, the opening diameters of the charging port and the discharging port are slightly larger than the opening diameter of the metering chamber.

When the additive filling is completed, the driving motor 113 drives the driving belt 112 installed on the outer circumference of the upper metering container 105, thereby driving the upper metering container 105 to rotate back and forth several times in a small amplitude, thereby increasing the filling rate of the additive 110 in the first metering chamber 107. The rotation angle at this time is approximately the degree to which the opening of the first metering chamber 107 or the second metering chamber 108 can be blocked by the inlet shutter plate 101 or the outlet shutter plate 103. After this operation is completed, the upper and lower metering containers are rotated by 180 ° from the state where the opening portions are overlapped, and the discharge port 104 of the discharge port shutter plate 103 and the opening position of the first metering chamber 107 are overlapped, so that the filled additive 110 falls into the additive tank 201.

When the additive is discharged, the second metering chamber 108 is moved to the inlet 102 of the inlet shutter plate 101, and the additive 110 in the first metering chamber 107 is discharged and the additive 110 in the second metering chamber 108 is completely filled. In order to completely discharge the additive in the first metering chamber 107 and simultaneously allow the second metering chamber 108 to receive more additive, the driving motor 113 is rotated back and forth several times with a small amplitude to shake the two cylindrical metering chambers 107 and 108, so that the shaking of the metering chamber 107 acts on the powder accumulation in the average metering chamber to load more powder, and the shaking provided by the driving motor 113 acts on the other metering chamber 108 synchronously, so that the additive stuck on the inner wall is shaken off, more powder is discharged, the residue is reduced, and the rotation angle is the same as the rotation angle after the filling is finished. After the additive in the first metering chamber 107 is discharged and the additive in the second metering chamber 108 is filled, the vertical metering container is rotated in the forward or reverse direction from the illustrated position by 180 ° in any direction, and the operation is stopped after the vertical inlets of the first metering chamber 107 and the second metering chamber 108 are closed by the shutter plates 101 and 103.

Further, the 2 cylindrical measuring chambers attached to the upper and lower measuring containers have an up-and-down fitting structure, and the length of the up-and-down fitting can be adjusted, so that the capacities of the first measuring chamber 107 and the second measuring chamber 108 can be changed. The fitting length can be adjusted by the measuring chamber volume adjusting knob 114. When the volume adjustment knob 114 of the metering chamber is rotated, the worm 115 is rotated, and the worm wheel 116 attached to the rotary shaft 109 is rotated, and the rotary shaft 109 is a ball screw which passes through a ball nut 117 attached to the discharge port shutter 103. Thus, by rotating the measuring chamber capacity adjustment knob, the rotary shaft 109 is rotated, and the discharge port shutter plate 103 is moved upward or downward along the direction of the rotary shaft. And the lower metering container 106, which is also located above the discharge port shutter plate 103, is also interlocked. In addition, a compression spring 118 is provided between the upper measuring container 105 and the lower measuring container 106, so that the measuring chamber can be flexibly extended and contracted, and no gap is generated between the upper measuring container 105 and the inlet shutter plate 101 and between the lower measuring container 106 and the outlet shutter plate 103. The additive amount can be freely controlled by adjusting the volume of the metering chamber and changing the number of times of adding the additive.

Referring to fig. 3, the operation of the control module 300 for controlling the linkage of the powder dosing assembly 100 and the dissolving assembly 200 will be described.

The first major prerequisite is to put the additives into water for dissolution. On the other hand, many water-soluble polymers are difficult to dissolve because they are so difficult to form large agglomerates called "hard lumps" or "lumps" because only the surface of the polymer dissolves and water cannot reach the inside of the polymer. Therefore, the device is also used for metering and dissolving the additive on the premise.

The drain valve 206 is opened first, the residual liquid in the tank is emptied, the liquid level sensor 202 senses that the residual liquid is emptied, and the drain valve 206 is closed. The water supply valve 204 opens the water supply. When the water level reaches about half the height of the tank, the water supply valve 204 is closed to stop the supply of water. The water stop position is preset by a liquid level sensor. After the water supply is stopped, the stirrer 203 starts stirring by rotation. After the start of the stirring, the powder dosing assembly 100 starts the dosing and the dosing of the additive. The thrown additive falls on the splash-proof screen 207 firstly and then falls into water, and the splash-proof screen 207 is mainly used for preventing large blocky additives from falling and preventing liquid splashing caused when the additives enter the water, so that additive powder is uniformly dispersed in the water and is convenient to dissolve. The screen of the splash guard 207 does not need to be particularly fine, but if it is too fine, it is smaller than the particle diameter of the additive powder, and the dropping of the additive powder is adversely affected, so that a relatively coarse screen can be selected. And after the quantitative additive falls into the mixing tank, the stirring time can be set at will, and the stirring is stopped after the set time is reached. After the stirring is stopped, the water supply valve 204 is opened to start adding water, and when the water level reaches the set position, the water supply valve 204 is closed, the stirrer is started again to stir the liquid in the tank uniformly. The intermediate stirring is stopped mainly to prevent the liquid level fluctuation caused by stirring from causing that the sensor cannot sense the correct liquid level. The stirring time, although arbitrary, must be long enough to ensure complete dissolution of the additive. After the additives are completely dissolved, the additive liquid supply valve 205 is opened to start supplying liquid into the electrolyte, and the electrolytic copper foil is required to be accurately supplied according to the electrolytic consumption of the additives in the production process. Such as a diaphragm pump.

The utility model discloses a simple and excellent design has designed one kind and can add the device of powder to additive jar according to predetermined amount automatically, and the device can be used to the additive in the electrolytic copper foil additive production to join in marriage the liquid operation, and it not only can realize full-automaticly, and totally closed joins in marriage liquid, and need not the manual work, is difficult for makeing mistakes, improves production efficiency greatly.
