Description

Technical Field

[0001] The present application relates to the technical field of conductive rollers, and in particular to a conductive roller assembly. Background Art

[0002] Conductive roller is an electrical conduction device widely used in the industrial field, mainly used to conduct current from one location to another to complete the circuit.

[0003] Existing conductive rollers are usually made of metal materials, and their main function is to transfer current and guide materials through specific processing processes, such as electroplating, electrolysis, etc. They are particularly important in industries such as printing, textiles, plastics and rubber processing.

[0004] The existing conductive rollers need to pay attention to the roughness of the roller surface. At the same time, the existing conductive rollers generally need to be filled with coolant to remove the heat generated by the conductive rollers when they are powered on, so as to ensure the electrical performance of the entire conductive rollers.

[0005] During the use of electrolytic copper foil, the existing conductive roller has a local overtemperature, which causes defects on the copper foil surface. At the same time, when the copper foil is pulled out, the bath liquid inside the electrolytic cell will also stick to the conductive roller. Since it cannot be cleaned in time, the acidic bath liquid will remain for too long, which will cause a certain degree of corrosion to the conductive roller, thereby affecting the conductive performance of the entire conductive roller. Summary of the invention

[0006] The present application provides a conductive roller assembly, which can solve the problems of the existing conductive roller being corroded by acidic tank liquid adhering to the surface, thereby affecting its conductive performance, and the low heat dissipation efficiency of the conductive roller.

The blowing device blows air toward the conductive roller body to dissipate heat from the surface of the conductive roller body and accelerate the blowing off of the tank liquid on the surface of the conductive roller body.

[0008] By adopting the above scheme, the conductive roller body is arranged on the conductive bracket to rotate and conduct the current to the tank liquid. As the conductive roller body rotates, the blowing device is arranged above the conductive roller body and blows air downward, so that the conductive roller body can be air-cooled, which accelerates the heat dissipation effect of the conductive roller body and accelerates the blowing of the tank liquid on the surface of the conductive roller body, thereby reducing the tank liquid attached to the surface of the conductive roller body for a long time, effectively reducing the acid corrosion of the conductive roller body due to the tank liquid, and can also improve the convenience of cleaning the surface of the conductive roller body.

[0011] By adopting the above scheme, an integrally formed copper lining is provided, which has better electrical conductivity than a spliced ​​copper lining, and can also avoid the problem of large resistance at the welding point of the copper lining and serious heat generation due to welding. At the same time, a cold joint provided in the connecting pipe of the conducting cavity inside the copper lining is used to pass pure water coolant into the conducting cavity, thereby absorbing the heat of the copper lining and further reducing the heat generation of the conductive roller body when power is supplied.

The conductive copper ring is electrically connected to the conductive end head and the power supply device.

[0015] By adopting the above scheme, the conductive copper ring is set on the fixed ring, so that the conductive end can rotate inside the missile copper ring while the current of the power supply equipment flows into the conductive end through the conductive copper ring, thereby making the entire conductive roller body charged.

[0016] In one embodiment of the present application, the blowing device comprises: A connecting frame, the connecting frame is assembled above the supporting frame; An air cooling trough is mounted on the connecting frame and is located above the conductive roller body. An air pipe connected to an air pump is provided on the air cooling trough for directing air flow to the conductive roller body to cool the conductive roller body and blow off the trough liquid on the surface of the conductive roller body.

[0017] By adopting the above scheme, the blowing device is arranged above the conductive roller body, and the air cooling groove can blow the air flow to the conductive roller body located below it, which can assist the internal coolant to dissipate heat and blow off the groove liquid attached to the surface of the conductive roller body in time, thereby reducing the cost of subsequent manual cleaning and reducing the occurrence of corrosion of the conductive roller body.

[0018] In one embodiment of the present application, the connecting frame includes: A column assembly, the height of which is adjustable and which is assembled on the upper end of the fixing ring; A movable frame, one end of which is connected to the column assembly, and the other end of which is connected and fixed to the air cooling slot.

[0020] In one embodiment of the present application, the movable frame includes two movable plates, one end of the two movable plates is respectively connected and fixed to the active sleeve and the driven sleeve, and the other end is respectively assembled on the two ends of the air cooling groove.

[0021] By adopting the above scheme, by setting up a height-adjustable column assembly, the height of the air cooling groove can be adjusted according to actual working conditions, so that the height distance of the air cooling groove can be adjusted above the conductive roller body, ensuring the air outlet intensity of the air cooling groove while allowing it to be close to the conductive roller body.

[0022] In one embodiment of the present application, an air flow cavity is provided inside the air cooling groove, strip-shaped air outlet holes are provided at the bottom of the air cooling groove along its length direction, and the air pipe is connected to the air flow cavity.

[0023] By adopting the above solution, strip-shaped air outlet holes parallel to the length direction of the conductive roller body are provided, so that when the air cooling groove is discharging air, the wind pressure is stronger and more closely fits the shape of the conductive roller body.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting it above the conductive roller body and blowing air downward, the conductive roller body can be air-cooled, which accelerates the heat dissipation effect of the conductive roller body and accelerates the blowing off of the tank liquid on the surface of the conductive roller body, thereby reducing the time for the tank liquid to adhere to the surface of the conductive roller body, thereby reducing the corrosion of the conductive roller body due to the adhesion of the acidic tank liquid, and can also improve the convenience of cleaning the conductive roller body.

[0032] See also Figure 1 The copper lining 12 is an integrally formed copper component. The integrally formed copper component is used as the copper lining 12 to improve the heat dissipation effect of the device while avoiding the problem of high resistance at the welding point caused by splicing the copper lining 12, thereby avoiding the occurrence of serious heat generation.

[0035] See also Figure 1 and Figure 3 The blowing device 3 includes: a connecting frame 31 and an air cooling groove 32. The connecting frame 31 is installed above the supporting frame 21.

The air cooling groove 32 is provided with an air pipe 321 connected to an air pump for guiding the airflow to the conductive roller body 1 to cool the conductive roller body 1 and blow off the tank liquid on the surface of the conductive roller body 1. By setting the air cooling groove 32, the air cooling groove 32 is used to blow a high-speed airflow to the conductive roller body 1. When the airflow reaches the conductive roller body 1, the conductive roller body 1 is cooled and dissipated by air, and the acidic tank liquid attached to the outside of the conductive roller body 1 can also be blown off, which greatly reduces the time for the tank liquid to corrode the conductive roller body 1 with acid.

[0036] The connecting frame 31 includes: a column assembly 311 and a movable frame 312. The height of the column assembly 311 is adjustable. The column assembly 311 is assembled on the upper end of the fixed ring 22. One end of the movable frame 312 is connected to the column assembly 311, and the other end of the movable frame 312 is connected and fixed to the air cooling groove 32. By providing a column assembly 311 with adjustable height, the height of the movable frame 312 can be adjusted, and then the height of the air cooling groove 32 can be adjusted.

[0037] See also Figure 3 The column assembly 311 includes: two threaded rods 3111, a driving sleeve 3112 and a driven sleeve 3113. The two threaded rods 3111 are fixedly assembled on the fixed ring 22. The driving sleeve 3112 and the driven sleeve 3113 are coaxially sleeved on the two threaded rods 3111 respectively. The lower end of the driving sleeve 3112 is coaxially rotatably connected with a threaded ring 3114. The threaded ring 3114 is threadedly connected to the threaded rod 3111. When adjusting the height of the movable frame 312, the driving sleeve 3112 and the driven sleeve 3113 can be lifted and lowered along the two threaded rods 3111 by rotating the threaded ring 3114.

[0040] See also Figure 2 An air flow cavity 322 is provided inside the air cooling groove 32, and a strip air outlet hole 323 is opened at the bottom of the air cooling groove 32 along its length direction. A plurality of air pipes 321 connected to the air pump are provided at the top of the air cooling groove 32, and the air pipes 321 are communicated with the air flow cavity 322, wherein the width of the strip air outlet hole 323 is smaller than the width of the air flow cavity 322, so that the air flow enters the air flow cavity 322 after being pressurized by the air pump, and is blown out at the strip exhaust hole. Since the width of the strip air outlet hole 323 is small, the air flow can be further pressurized when it is blown out from the strip air outlet hole 323, so that the air flow blows toward the conductive roller body 1 at a high speed.

[0041] In this embodiment, an air pump (not shown) is further included, and the output end of the air pump is connected to the air pipe 321 through the ventilation pipe 321.

[0042] In summary, when the device is needed to electrolyze copper foil, the lower end of the conductive roller body 1 is immersed in the tank liquid, and as the electrolysis process progresses, copper ions are precipitated at the lower end of the conductive roller body 1 to form copper foil. As the conductive roller rotates, the copper foil is rolled up along with the conductive roller body 1. At this time, the air pump and the liquid pump are turned on. The liquid pump can be used to pump pure water coolant into one end of the copper lining 12 and into the internal cooling cavity 120, thereby absorbing the heat generated by the copper lining 12 after being energized. The pure water after absorbing the heat flows out from the other end, thereby completing the circulation of the coolant. At the same time, during the electrolytic copper foil process of the conductive roller main body 1, the blowing device 3 continuously blows high-speed airflow toward the conductive roller main body 1, which can further accelerate the heat dissipation capacity of the conductive roller main body 1 and accelerate the blowing off of the bath liquid carried by the copper foil, thereby reducing the time the bath liquid adheres to the conductive roller main body 1, thereby reducing the possibility of corrosion to the conductive roller main body 1, ensuring the smoothness of the surface of the conductive roller main body 1, and improving the electrical performance of the entire conductive roller main body 1.
