Abstract
Description
Technical Field
[0001] This utility model relates to the field of copper strip cleaning technology, specifically a copper strip cleaning structure. Background Technology
[0002] Currently, users have increasingly higher requirements for the surface cleanliness of copper strips and plates; for example, the residual oil content on the surface of some frame materials is even required to reach 5 mg / m³. 2 Therefore, for products with high surface cleanliness requirements, cleaning treatment must be carried out during processing to remove residual oil, metal oxides and other contaminants; while copper strips need to undergo rough cleaning and finished product cleaning during production. The current cleaning method involves using multiple guide rollers to turn the copper strip as it enters the cleaning chamber and then exits it. This method requires the copper strip to undergo multiple 90° turns, which can cause some damage and oxidation to the surface of the copper strip.
[0003] Therefore, in order to correct the above-mentioned defects, we propose a copper strip cleaning structure. Utility Model Content
[0004] The technical problem solved by this utility model is to propose a copper strip cleaning structure.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a copper strip cleaning structure, including a cleaning liquid tank, an inlet valve and a drain valve door installed on the cleaning liquid tank, an immersion tank above the cleaning liquid tank, the immersion tank being supported on the cleaning liquid tank by a support frame, openings in the middle of both sides of the immersion tank, through which the copper strip passes. Both the immersion tank and the cleaning liquid tank are equipped with connecting valves. The connecting valve on the immersion tank is connected to a flexible hose, and the connecting valve on the cleaning liquid tank is connected to a rigid pipe. The flexible hose and the rigid pipe are connected. A pump body is installed inside the cleaning liquid tank, and the pump body is connected to the connecting valve on the cleaning liquid tank. The length and width of the immersion tank are smaller than the length and width of the cleaning liquid tank, and a sealing strip is embedded in the opening.
[0006] Furthermore, the soaking tank includes an upper half and a lower half, with the upper half stacked on top of the lower half. Openings are formed on both sides of the upper half, and positioning screws are installed on the side walls of the lower half, supporting the upper half.
[0007] Furthermore, both the upper and lower half of the box are equipped with sealing gaskets.
[0008] Furthermore, the soaking tank is provided with guide plates on both sides, and the guide plates are located below the opening.
[0009] Furthermore, flow guiding components are installed on both sides of the interior of the cleaning fluid tank. The flow guiding components are located below the opening. The flow guiding components include a vertical frame, an auxiliary frame is installed inside the vertical frame, and filter cotton is embedded in the auxiliary frame.
[0010] Furthermore, the vertical frame has inner grooves at both ends, and the auxiliary frame has protrusions at both ends. When the auxiliary frame is placed inside the vertical frame, the protrusions are movably embedded in the inner grooves, and the vertical frame is fixed to the inner wall of the cleaning fluid tank.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the cleaning structure of this utility model allows the copper strip to travel in a straight line in the cleaning box without having to turn multiple times, preventing damage and oxidation to the surface of the copper strip, and allowing the cleaning liquid in the cleaning box to circulate in real time.

Detailed Implementation
[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] This utility model provides a technical solution: Please see Figure 1-5 A copper strip cleaning structure includes a cleaning solution tank 1, an inlet valve 8 and a drain valve door 13 installed on the cleaning solution tank 1, an immersion tank 3 above the cleaning solution tank 1, the immersion tank 3 being supported on the cleaning solution tank 1 by a support frame 2, openings 4 in the middle of both sides of the immersion tank 3, through which the copper strip passes. Both the immersion tank 3 and the cleaning solution tank 1 are equipped with connecting valves 5. The connecting valve 5 on the immersion tank 3 is connected to a flexible hose 6, and the connecting valve 5 on the cleaning solution tank 1 is connected to a rigid pipe 7. The flexible hose 6 is connected to the rigid pipe 7. A pump body is installed inside the cleaning solution tank 1, and the pump body is connected to the connecting valve 5 on the cleaning solution tank 1. The length and width of the immersion tank 3 are smaller than the length and width of the cleaning solution tank 1, and a sealing strip is embedded in the opening 4.
[0015] The cleaning solution in the cleaning solution tank 1 is discharged into the soaking tank 3 through components such as pump body and pipes. Multiple sets of these components are provided to ensure that the liquid inflow into the soaking tank 3 is greater than the liquid outflow. In this way, the liquid level in the soaking tank 3 is greater than the height of the opening 4. The copper strip enters the soaking tank 3 from the opening 4 on one side of the soaking tank 3. At this time, the copper strip entering the soaking tank 3 is completely soaked in the cleaning solution, and then exits from the opening 4 on the other side of the soaking tank 3.
[0016] In the above, the sealing strip embedded in the opening 4 can deform and stick to the copper strip when the copper strip passes through, thus reducing the amount of cleaning liquid overflowing from the opening. In order to ensure that the copper strip is thoroughly cleaned, the length of the soaking tank 3 can be set to be longer, and a support roller can be added inside the soaking tank 3 to support the copper strip. The soaking tank 3 can also be equipped with cleaning rollers and brushes, just like the cleaning structure in the prior art.
[0017] To facilitate the entry of the copper strip into the soaking tank 3 in its initial state, the soaking tank 3 includes an upper half 31 and a lower half 32. After the front part of the copper strip is placed in, the upper half 31 is stacked on top of the lower half 32. Openings 4 are opened on both sides of the upper half 31. Positioning screws are installed on the side wall of the lower half 32. The positioning screws support the upper half 31. The opening 4 is an inverted U-shape. When the upper half 31 is stacked on top of the lower half 32, the opening 4 overlaps with the side wall of the lower half 32. The deeper the upper half 31 is stacked, the smaller the depth of the opening 4.
[0018] To ensure the airtightness between the upper half box 31 and the lower half box 32, sealing gaskets are provided on the overlapping parts of the upper half box 31 and the lower half box 32.
[0019] In addition, the soaking tank 3 is equipped with guide plates on both sides, which are located below the opening 4. The cleaning liquid flowing out of the opening 4 flows back into the cleaning liquid tank 1 along the guide plates.
[0020] Based on the above, flow guiding components are installed on both sides of the inside of the cleaning fluid tank 1. The flow guiding components are located below the opening 4. The flow guiding components include a vertical frame 10, an auxiliary frame 11 is installed inside the vertical frame 10, and a filter cotton 12 is embedded in the auxiliary frame 11. That is, the cleaning fluid flowing out of the opening 4 flows into the flow guiding components along the guide plate 9 and then completely returns to the cleaning fluid tank 1. The aforementioned flow guiding component can filter out impurities in the cleaning fluid and allow the cleaning fluid to flow down along the filter cotton 12, which can reduce the water flow noise generated when the cleaning fluid flows back.
[0021] The vertical frame 10 has inner grooves at both ends, and the auxiliary frame 11 has protrusions at both ends. When the auxiliary frame 11 is placed inside the vertical frame 10, the protrusions are movably embedded in the inner grooves, and the vertical frame 10 is fixed to the inner wall of the cleaning fluid tank 1. The subframe 11 can be pulled out from the vertical frame 10 to clean or replace the filter cotton 12.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
