TECHNICAL FIELD

[0001] The utility model relates to the technical field of copper foil production equipment, specifically related to a kind of spraying structure for copper foil washing tank. BACKGROUND

[0002] Water washing tank spraying is the most basic equipment in electroplating equipment, and its main function is to spray and wash the residual plating solution on the surface of workpiece after electroplating, so as to facilitate the subsequent process, avoid the pollution of subsequent tank solution or the product defect caused by unclean product surface, and improve the stability of electroplated foil surface. The conventional water washing spraying tank is provided with a spraying head in the tank for spraying and cleaning. However, when the water pressure is insufficient, the spraying angle cannot be fully expanded, and the copper foil surface cannot be completely covered and cleaned. Therefore, it is easy to leave residues in the gap, and the joint position is more difficult to clean, which may pollute the subsequent tank solution and affect the stability of the electroplated foil surface. Therefore, the spraying structure for copper foil washing tank needs to be improved. SUMMARY

[0003] In view of the above technical problems in the related art, the utility model provides a spraying structure for copper foil washing tank, which can solve the above problems.

[0004] To achieve the above technical purpose, the technical scheme of the utility model is as follows:

[0005] A spraying structure for copper foil washing tank, comprising a washing tank, a submerged roll, a water distributor assembly, and a double-layer spraying structure. The water distributor assembly comprises a horizontal pipe body, a plurality of branch joint groups arranged on the surface of the horizontal pipe body, and a manual stop valve connected to the top end of the horizontal pipe body. The double-layer spraying structure comprises an upper spraying structure and a lower spraying structure. Both the upper spraying structure and the lower spraying structure comprise two horizontally arranged spraying pipe supports, a plurality of spraying pipe limiting structures slidably arranged below the spraying pipe supports, and a plurality of spraying pipes. Each spraying pipe is provided with a plurality of nozzles at equal intervals, and each spraying pipe is provided with a water inlet joint at the bottom. The branch joint groups of the water distributor assembly are connected to the water inlet joints by hoses.

[0006] Further, a sliding groove is formed in the middle of the spraying pipe support, and the spraying pipe limiting structure comprises a screw rod, a square pedestal and a sleeve, which are fixedly connected in sequence from top to bottom. The screw rod is arranged in the sliding groove, and one end of the screw rod passing through the sliding groove is threadedly connected with a nut.

[0007] Further, a rubber gasket ring is bonded to the inner wall of the sleeve, and a plurality of protrusions are integrally formed on the inner wall surface of the rubber gasket ring. The end of the spraying pipe close to the surface of the spraying pipe is provided with a narrow edge.

[0008] Further, the nozzles are isosceles trapezoidal in shape, and the end of the nozzle close to the surface of the spraying pipe is provided with a narrow edge.

[0009] Furthermore, there are two upper spray structures and two lower spray structures, and both upper and lower spray structures are symmetrically arranged about the front and rear of the liquid roller.

[0010] Furthermore, the number of branch joint groups matches the number of sprinkler pipe supports, and the number of branch joints in a branch joint group is the same as the number of sprinkler pipes on a single sprinkler pipe support.

[0011] The beneficial effects of this utility model are as follows: The device of this application sets upper and lower spray structures on both sides of the path of the copper foil passing through the liquid roller, so that both sides of the copper foil are fully sprayed and cleaned, which can greatly improve the quality of the copper foil. The spray structure is equipped with an adjustable spray pipe limiting structure to cooperate with the spray pipe, which facilitates the installation of multiple short spray pipes and avoids the problem of low water pressure of the nozzle far from the water inlet end that exists when using long spray pipes. The spray angle of each spray pipe can be adjusted independently to achieve efficient and low-consumption copper foil surface cleaning. Attached Figure Description

[0020] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0021] like Figures 1-4 As shown, this utility model discloses a spray structure for a copper foil washing tank, including a washing tank 1, a liquid roller 2, a water distributor assembly 3, and a double-layer spray structure. The water distributor assembly 3 includes a horizontal pipe body and several branch joints 302 connected to the surface of the horizontal pipe body. A manual shut-off valve 301 is connected and installed at the top of the horizontal pipe body. The double-layer spray structure includes an upper spray structure 4 and a lower spray structure 10. Both the upper spray structure 4 and the lower spray structure 10 include two horizontally arranged spray pipe supports 401 and several sliding adjustment components on the spray pipes. Below the spray pipe support 401 is a spray pipe limiting structure 5 and several spray pipes 6. Each spray pipe 6 is equidistantly connected with several nozzles 7. Each spray pipe 6 has a water inlet connector 8 connected to its bottom. The branch connector group 302 of the water distributor assembly 3 is connected to the water inlet connector 8 through a hose. On the two horizontally arranged spray pipe supports 401, the nozzles 7 of the two opposite spray pipes 6 are all facing the opposite spray pipe. That is, when the copper foil passes through the two horizontally arranged spray pipe supports 401, the two opposite spray pipes 6 spray the two sides of the copper foil respectively.

[0022] The spray pipe support 401 has a through groove 402 in the middle. The spray pipe limiting structure 5 includes a screw 501, a square base 503 and a sleeve 504 that are fixedly connected from top to bottom. The screw 501 passes through the groove 402 and a nut 502 is threaded to one end of the screw 501 that passes through the groove 402.

[0023] Example 1: Spray pipe bracket 401 has mating plates at both ends. The spray pipe bracket 401 is fixed to the pre-drilled screw holes in the washing tank 1 using bolts. Each spray pipe bracket 401 has four spray pipe limiting structures 5 and three spray pipes 6. The diameter of the screw 501 in the spray pipe limiting structure 5 is the same as the inner diameter of the slide 402. The side length of the square base 503 is greater than the diameter of the screw 501. Therefore, when the screw 501 passes through the slide 402, the square base 503 abuts against the bottom of the slide 402. One end of the screw 501 passing through the slide 402 is threaded with a nut 502. The nut is not tightened initially; it is tightened only after all three spray pipes 6 are installed in the rubber sleeve 504. Tighten the nuts inside the rubber gasket ring 9. The two ends of the spray pipe 6 are in frictional contact with the rubber gasket ring 9, which can adjust the spray angle of the spray pipe 6 and prevent the spray pipe 6 from rotating easily due to the friction of the rubber gasket ring 9. The branch joint group 302 of the water distributor assembly 3 passes through the water washing tank 1 and the penetration point is sealed. The joint of the branch joint group 302 and the water inlet joint 8 are both conventional pressurized liquid conveying joints. The pipes at the joints are tightened with clamps. The joint of the branch joint group 302 is connected to the water inlet joint 8 through a hose. The manual shut-off valve 301 is connected to the water source through a pipeline. The water source needs to be pressurized by a water pump or its own pressure ≥0.12MPa.

[0024] In the preferred technical solution, a rubber gasket 9 is bonded to the inner wall of the sleeve 504. The inner wall surface of the rubber gasket 9 is integrally formed with protruding teeth. The end of the spray pipe 6 is fitted inside the rubber gasket 9. The rubber gasket 9, in conjunction with the protruding teeth on the inner wall surface, is used to make frictional contact with the end of the spray pipe 6. The friction of the rubber gasket 9 prevents the spray pipe 6 from rotating easily, so that the spray pipe 6 does not easily rotate after the angle is adjusted.

[0025] In the preferred technical solution, the nozzle 7 is an isosceles trapezoidal shape, the end of the nozzle 7 that is close to the surface of the spray pipe 6 is a narrow end, the nozzle of the nozzle 7 is flat, the inlet is narrow and the outlet is wide, and it is used to spray a wide range of water flow.

[0026] In the preferred technical solution, there are two upper spray structures 4 and two lower spray structures 10. The two upper spray structures 4 and the two lower spray structures 10 are symmetrically arranged about the front and back of the liquid roller 2. The upper spray structure 4 and the lower spray structure 10 are arranged on the path of the copper foil entering and exiting the liquid roller 2. Both sides of the copper foil are fully sprayed and cleaned, realizing efficient and low-consumption copper foil surface cleaning, which can greatly improve the quality of the copper foil.

[0027] In practical use, the copper foil enters from one side below the liquid roller 2 and exits from the other side below the liquid roller 2. An upper spray structure 4 and a lower spray structure 10 are provided on the path of the copper foil entering and exiting the liquid roller 2. When the manual shut-off valve 301 is opened, the cleaning liquid passes through the water distributor assembly 3, the branch connector group 302, the hose, the water inlet connector 8, the spray pipe 6, and finally sprays out from each nozzle 6, which can spray and clean both sides of the copper foil.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
