[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-6 , the present invention provides a technical solution:

[0026] In specific use, when the device is used to electroplate metal, the metal can first be sent into the electroplating box 4 through the transmission mechanism 11, so that the branch electrode 9 can be used to electroplate the metal inside the electroplating box 4. At the same time, the air pump 5 adds gas to the transition box 2 through the second air pipe 7, so that the liquid inside the transition box 2 can pass through the guide pipe 8, thereby continuously sending the liquid to the bottom position of the electroplating box 4 through the guide pipe 8, and exerting a force on the metal inside the electroplating box 4, so that the metal does not fall to the bottom of the electroplating box 4 when it is not fixed, thereby making it easier to electroplate the entire metal through the branch electrode 9, and The auxiliary mechanism 13 at the bottom of the guide pipe 8 also plays an auxiliary floating role for the metal. While the electroplating box 4 is electroplating the metal, the guide mechanism 10 and the air pump 5 exhaust the inside of the electroplating box 4 through the first air pipe 6, so that the liquid inside the electroplating box 4 can flow, and the metal can move inside the electroplating box 4 while the electroplating is being carried out. After the electroplating box 4 has completed the treatment of the metal, the discharge mechanism 12 can be used to make it easier for the metal to be removed from the electroplating box 4. In addition, the inside of the electroplating box 4 can continuously add metal, and the metal can flow out after the treatment is completed, thereby improving the efficiency of the overall device for metal electroplating.

[0027] In this embodiment: a water pump 14 is fixedly installed on the top of the liquid storage tank 3, and the liquid inlet of the water pump 14 is connected to an extraction pipe 15, and the liquid inlet of the extraction pipe 15 is interconnected with the interior of the liquid storage tank 3, and a branch pipe 16 is fixedly installed at the liquid outlet of the water pump 14, and a liquid flow layer 17 is fixedly installed on the inner wall of the transition box 2, and a plurality of strong flow pipes 18 are fixedly installed on the top of the liquid flow layer 17, and a liquid storage cavity 19 flows through the bottom ends of the plurality of strong flow pipes 18, and the liquid outlets of the branch pipes 16 are respectively interconnected with the liquid storage cavity 19 and the interior of the transition box 2.

[0028] During specific use, when there is insufficient liquid in the transition box 2, the water pump 14 can extract the liquid in the liquid storage tank 3 through the extraction pipe 15, thereby sending the liquid into the transition box 2 through one of the branches of the branch pipe 16. When the metal in the electroplating box 4 is electroplated, the water pump 14 can send the liquid into the liquid storage chamber 19 through another branch of the branch pipe 16, thereby sending the fast-flowing liquid in the liquid storage chamber 19 to the top of the liquid flow layer 17 through the strong flow pipe 18, so that the metal at the top of the liquid flow layer 17 can quickly float to the top of the electroplating box 4, thereby making it easier to move the metal to the outside of the electroplating box 4 through the discharge mechanism 12.

[0029] In this embodiment: the guide mechanism 10 includes a plurality of first rotating rods 101 rotatably connected to the two ends of the electroplating box 4, a first guide fan 102 is fixedly installed at one end of the plurality of first rotating rods 101, a first rotating wheel 103 is fixedly installed at the other end of the first rotating rod 101, a first belt 104 is sleeved on the outer side of the first rotating wheel 103, and a first rotating motor 105 is fixedly installed at one end of one of the first rotating rods 101.

[0030] During specific use, while the electroplating box 4 is electroplating the metal, the first rotating motor 105 can act on one of the first rotating rods 101, thereby the first rotating wheel 103 and the first belt 104 can make all the first rotating rods 101 rotate, and then the first guide fans 102 on both sides of the electroplating box 4 can guide the liquid inside the electroplating box 4, so that the liquid inside the electroplating box 4 can flow continuously, so that the waste liquid generated after the metal electroplating is continuously discharged together with the treated metal through the discharge mechanism 12, thereby improving the metal treatment effect of the overall device and improving the metal treatment efficiency of the overall device.

[0031] In this embodiment: the transmission mechanism 11 includes two transmission wheels 111 rotatably connected to the top of the electroplating box 4, and the outer sides of the two transmission wheels 111 are provided with a conveyor belt 112, and the two ends of one of the transmission wheels 111 are fixedly installed with a second rotating rod 113, and one end of one of the first rotating rod 101 and the second rotating rod 113 is fixedly installed with a second rotating wheel 114, and the outer sides of the two second rotating wheels 114 are provided with a second belt 115.

[0032] During specific use, when the metal needs to be sent into the electroplating box 4, the first rotating motor 105 can be rotated, and through the action of the second rotating wheel 114 and the second belt 115, the second rotating rod 113 can be rotated synchronously with the first rotating rod 101, and then the transmission wheel 111 and the conveyor belt 112 can be transmitted synchronously, so that the metal to be processed placed on the conveyor belt 112 can be sent to the inside of the electroplating box 4 for electroplating treatment.

[0033] In this embodiment: the discharge mechanism 12 includes a storage groove 121 opened on one side of the top of the electroplating box 4, and the interior of the storage groove 121 is slidably connected with a waterproof plate 122, and two electric hydraulic rods 123 are fixedly installed at the bottom of the waterproof plate 122, and the fixed ends of the two electric hydraulic rods 123 are fixedly connected to the interior of the storage groove 121.

[0034] During specific use, after the metal is electroplated and floated to the top of the electroplating box 4 through the strong flow pipe 18, the electric hydraulic rod 123 inside the storage tank 121 can be used to enable the waterproof plate 122 to be lifted and slid inside the storage tank 121, and then the waterproof plate 122 is lowered to discharge the treated metal and the treated waste liquid inside the electroplating box 4 together.

[0035] In this embodiment: the auxiliary mechanism 13 includes two rotating shafts 131 rotatably connected to the inner side of the bottom of the electroplating box 4, a second guide fan 132 is fixedly installed on the outer side of the two rotating shafts 131, and a main gear 133 is fixedly installed at both ends of the rotating shaft 131, and a transition gear 134 is meshedly connected to one side of the main gear 133, and one end of the transition gear 134 is rotatably connected to the outer side of the electroplating box 4, and a second rotating motor 135 is fixedly installed on one side of one of the transition gears 134.

[0036] During specific use, while the electroplating box 4 is electroplating the metal, the second rotating motor 135 can also drive the transition gear 134 to rotate, so that the main gear 133 can rotate in a certain direction and drive the rotating shaft 131 to rotate, so that the second guide fan 132 outside the rotating shaft 131 can squeeze the liquid at the bottom of the electroplating box 4 upward, so that the buoyancy of the bottom of the electroplating box 4 on the metal is improved, thereby improving the electroplating effect of the overall device on the metal.

[0037] In this embodiment: electric valves 20 are fixedly installed on the outer sides of the first air pipe 6 and the branch pipe 16, a conduit 21 is inserted and connected to one side of the transition box 2, a display column 22 is fixedly installed at the outlet of the conduit 21, a water level sensor 23 is fixedly installed on the inner side of the display column 22, and an auxiliary guide plate 24 is fixedly installed on the outer side of the electroplating box 4.

[0038] In specific use, when the electroplating box 4 processes the metal, the electric valve 20 can be used to open the first air pipe 6, so that the air pump 5 can pass through the first air pipe 6 to rush the gas into the electroplating box 4, so that the metal at the front position of the electroplating box 4 can move to the rear position. When the metal processing is completed, the electric valve 20 can be used to open one of the branches of the branch pipe 16, so that the water pump 14 can quickly send the liquid into the liquid storage chamber 19 through the branch pipe 16, and act on the metal through the strong flow pipe 18, and the transition box 2 passes through the conduit 21 so that the display column 22 is level with the liquid level inside the transition box 2. When the liquid inside the transition box 2 is insufficient, the water pump 14 can be turned on by the induction of the water level sensor 23 inside the display column 22, so that the liquid inside the liquid storage tank 3 is sent into the transition box 2 through another branch of the branch pipe 16, thereby reducing the consumption of resources when the liquid is sufficient or the equipment is not in use. After the electroplating box 4 removes the metal, the auxiliary guide plate 24 plays a role of transition diversion for the metal, so as to facilitate the next step of processing of the metal.
