Description

Technical Field

[0001] The invention relates to the technical field of cathode copper stripping, and in particular to a stripping machine. Background Art

[0002] The electrolysis process of crude copper is usually to pre-form crude copper (containing 99% copper) into a thick plate as the anode, use a titanium plate or a stainless steel plate as the cathode, and use a mixture of sulfuric acid (H2SO4) and copper sulfate (CuSO4) as the electrolyte. After power is turned on, copper dissolves from the anode into copper ions (Cu) and moves to the cathode. After reaching the cathode, it obtains electrons and precipitates pure copper at the cathode. The copper plate produced in this way is called "cathode copper", also known as "electrolytic copper". The quality of cathode copper is extremely high and can be used to make electrical products. Figure 1 As shown, a cross bar 2 is provided on the upper part of the cathode plate 1. When the cathode plate 1 is placed in the electrolytic fin, the cross bar 2 is placed on a bracket provided next to the electrolytic cell. Most of the cathode plate 1 is immersed in the electrolyte. Copper is dissolved from the anode into copper ions (Cu), moves toward the cathode and adheres to the surface of the cathode plate 1 to form a cathode copper plate 3. After the electrolysis is completed, the cathode copper plate 3 needs to be peeled off from the cathode plate 1. Summary of the invention

[0003] The object of the present invention is to provide a stripping machine which can quickly strip a cathode copper plate from a cathode plate.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a stripping machine, including a frame, on which a bracket for supporting the two ends of the conductive cross bar A1 on the upper side of the cathode plate A is arranged, and frames are respectively arranged on both sides of the cathode plate A placed on the bracket, and the lower ends of the frames are hingedly connected by hinge shafts, and the axis core of the hinge shaft is located in the horizontal direction and parallel to the plate surface of the cathode plate A, and a pressing mechanism for pressing the cathode copper plate B on the cathode plate A is arranged on the frame, and the frame is rotated to a position adjacent to the cathode plate A, and the pressing mechanisms located on both sides are arranged in a staggered contact position with the cathode copper plate B, and a swinging knife mechanism is arranged on the upper part of the frame, and the swinging knife mechanism includes a knife plate, which is arranged along the radial direction of the rotating shaft and one end is fixed to the rotating shaft, and the knife plate rotates from a high position to a low position at the separation opening between the upper edges of the cathode plate A and the cathode copper plate B.

[0005] In the above scheme, first, the pressing mechanisms on both sides are staggered to contact and press the cathode copper plate B placed on the bracket, and a small separation opening appears between the upper end of the cathode copper plate and the cathode plate. Then, the knife plate of the swinging knife mechanism rotates from a high position to a low position at the separation opening between the cathode plate and the upper edge of the cathode copper plate, and the cathode copper plate is completely peeled off from the cathode plate.

[0013] According to the following Figure 1-Figure 7 The present invention is described in further detail.

[0014] A flaking machine includes a frame 10, on which a bracket 11 for supporting the two ends of a conductive cross bar A1 on a cathode plate A is provided, and frames 20 are respectively provided on both sides of the cathode plate A placed on the bracket 11, and the lower ends of the frames 20 are hingedly connected by hinge shafts 21, and the axis core of the hinge shaft 21 is located in the horizontal direction and parallel to the plate surface of the cathode plate A, and a pressing mechanism 30 for pressing a cathode copper plate B on the cathode plate A is provided on the frame 20, and the frame 20 is rotated to a position adjacent to the cathode plate A, and the contact pressing positions of the pressing mechanisms 30 located on both sides and the cathode copper plate B are staggered, and a swinging knife mechanism 40 is provided on the upper part of the frame 20, and the swinging knife mechanism 40 includes a knife plate 41, which is arranged along the radial direction of a rotating shaft 42 and one end of which is fixed to the rotating shaft 42, and the knife plate 41 rotates from a high position to a low position at a separation opening between the upper edges of the cathode plate A and the cathode copper plate B. When the frame 20 is transferred to a position away from the cathode plate A, the space between the two frames 20 is large enough. At this time, the two ends of the conductive cross bar A1 on the cathode plate A are placed on the bracket 11, and then the driving mechanism drives the frame 20 to transfer to a position close to the cathode plate A. The pressing mechanism 30 presses the cathode copper plate B on the cathode plate A in an offset manner, and a small separation opening appears between the upper end of the cathode copper plate B and the cathode plate A. However, at this time, most of the plate surface of the cathode copper plate B is still attached to the cathode plate A, so the knife plate 41 of the swinging knife mechanism 40 rotates from a high position to a low position at the separation opening between the upper edges of the cathode plate A and the cathode copper plate B, and the cathode copper plate B is completely peeled off from the cathode plate A.

[0015] Preferably, the distance between the blade edge and the blade back edge of the blade plate 41 gradually decreases from the fixed end connected to the rotating shaft 42 to the overhanging end.

[0016] In the actual production process, due to the multiple effects of installation, adjustment, and welding, the inclination angle of the blade 41 relative to the shaft 42 will change. For example, if it is tilted upward, the blade 41 may collide with the crossbar A1. If it is tilted too downward, it will collide with the cathode copper plate B. Therefore, a spline hole is provided on the blade 41 to cooperate with the spline shaft on the shaft 42. This transmission method can realize real-time adjustment of the angle of the blade 41 under any working conditions, ensuring that the copper plating layer of the cathode plate A and the crossbar A1 will not be damaged.

[0017] As a preferred embodiment of the present invention, the pressing mechanism 30 includes two parallel pressing rollers 31 which are sleeved on the roller shaft 32 at intervals and form a rotational fit. The roller cores of the two pressing rollers 31 are arranged in parallel with the axis core of the hinge shaft 21. The two ends of the roller shaft 32 are fixedly connected to the rotating shaft 34 arranged on the frame 20 through the connecting plate 33. The axis core of the rotating shaft 34 is arranged in parallel with the roller core of the pressing roller 31. The driving mechanism drives the rotating shaft 34 to rotate and drive the pressing roller 31 to press or move away from the surface of the cathode copper plate B on the cathode plate A. Before the frame 20 is transferred to a position close to the cathode plate A, the roller shaft 32 is in a position to avoid the cathode plate A. When the frame 20 is transferred to a position close to the cathode plate A, the driving mechanism drives the rotating shaft 34 to rotate and drive the pressing roller 31 to press the surface of the cathode copper plate B.

[0018] The pressing roller 31 is arranged at the middle position of the frame 20. When the frame 20 is transferred to a position close to the cathode plate A, the projections of the pressing rollers 31 on the left and right frames 20 on the cathode copper plate B are staggered. The positions where the two sides of the cathode copper plate B are pressed are different, generating shear force, so that the upper end of the cathode copper plate B is separated from the cathode plate A, and an opening appears.

[0019] The pressing mechanism 30 also includes an auxiliary roller 35 arranged at the lower part of the frame 20 near the cathode plate A. The roller core of the auxiliary roller 35 is located in the horizontal direction and is arranged parallel to the axis core of the hinge shaft 21. The auxiliary roller 35 is sleeved on the roller core shaft 39 and forms a rotational fit. The roller core shaft 39 is fixedly connected to the frame 20 through a transition rod 36. When the frame 20 is transferred to a position near the cathode plate A, the auxiliary roller 35 presses on the surface of the cathode copper plate B on the cathode plate A. When the frame 20 is transferred to a position near the cathode plate A, the auxiliary roller 35 presses on the surface of the cathode copper plate B on the cathode plate A to clamp and support the lower end of the cathode copper plate B. After the cathode copper plate B is peeled off from the cathode plate A, the cathode copper plates B on both sides can fall smoothly to the transfer unit below due to the limiting and guiding effects of the auxiliary roller 35.

[0020] In order to ensure the clamping force of the auxiliary roller 35, a spring 37 is sleeved on the rod body of the transition rod 36 after it passes through the frame 20. One end of the spring 37 is welded to the rod body of the transition rod 36, and the other end is against the bottom plate of the U-shaped mounting plate 38. A locking nut 39 is also provided on the rod body of the transition rod 36 outside the bottom plate. Two auxiliary rollers 35 are arranged at intervals in the width direction of the frame 20. The spring 37 provides elastic force to drive the auxiliary roller 35 to move toward the surface of the cathode copper plate B to ensure sufficient clamping force.

[0021] The bracket 11 includes a vertical rod 111, and a V-shaped block 112 with an upward opening is arranged at the top of the vertical rod 111. The distance between the V-shaped blocks 112 at the ends of the two vertical rods 111 is less than the length of the cross bar A1 at the upper end of the cathode plate A and is greater than the plate body width of the cathode plate A. The arrangement of the V-shaped block 112 can support the cross bar A1 without affecting the placement of the entire cathode plate A, and has a simple structure.

[0022] In order to ensure that the cathode copper plate B can be completely peeled off from the cathode plate A, a swing rod 113 is arranged on the lower rod section of the vertical rod 111 toward the cathode copper plate B, and a pressure head 114 is connected to the rod end of the swing rod 113. The driving mechanism drives the swing rod 113 to swing and drive the pressure head 114 to press down the cathode copper plate B or avoid the cathode copper plate B. In this way, after being peeled off by the swing knife mechanism 40, even if a part of the cathode copper plate B is not separated from the cathode plate A, the driving mechanism drives the swing rod 113 to swing and drive the pressure head 114 from the already opened place, and a downward pressure is applied to the cathode copper plate B from the opening position of the cathode copper plate B and the cathode plate A. In addition, the gravity of the cathode copper plate B itself can ensure that the cathode copper plate B can be completely peeled off from the cathode plate A; before this, the pressure head 114 has been in a position to avoid the cathode copper plate B, so as to prevent interference with the placement of the cathode plate A on the bracket 11, and interference with the frame 20 and the action of the pressing mechanism 30.

[0023] Furthermore, a support plate 50 is provided under the frame 10. The support plate 50 is a V-shaped plate with an opening facing upward. The driving mechanism drives the support plate 50 to reciprocate in the up and down directions. The lowest position of the support plate 50 is lower than the roller core height of the auxiliary roller 35. The length of the support plate 50 is smaller than the distance between the two auxiliary rollers 35. The V-shaped opening angle of the support plate 50 is larger than the lower end opening angle of the cathode copper plate B after stripping and smaller than the upper end opening angle of the cathode copper plate B after stripping. After the cathode copper plate B is peeled off from the cathode plate A, its lower end will fall into the V-shaped opening of the support plate 50, and then the driving mechanism drives the support plate 50 to move in the vertical direction. Due to gravity, the cathode copper plate B will also move downward with the support plate 50, and the lower end of the cathode copper plate B is pressed on the bottom surface of the V-shaped opening of the support plate 50. The lower surface of the cathode copper plate B is constrained by the two side plates of the support plate 50 and will not swing. The upper surface of the cathode copper plate B is guided by the auxiliary roller 35 during the downward movement and will not swing, thereby ultimately ensuring the stability of the falling of the cathode copper plate B.
