[0002] Electrolytic copper foil is an important material in the fields of copper clad laminates, printed circuit boards, lithium ion batteries, etc. In the current era of the rapid development of the electronic information industry, electrolytic copper foil is even known as the "neural network" for signal and power transmission and communication in electronic products. During the production process of electrolytic copper foil, its surface needs to be processed, and during the surface processing, it needs to be extruded by a conductive roller and a pressure roller, such as the content shown in the patent with the application publication number CN117721505A. However, in traditional roller pressing equipment, the pressing force between the conductive roller and the pressure roller is usually achieved by manually adjusting the relative position between the conductive roller and the pressure roller; and manual adjustment has randomness, which will directly affect the quality of products in different batches. Therefore, a pressure roller structure for stably adjusting the pressing force is needed. Summary of the Invention

[0018] It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present utility model in a schematic manner. Therefore, only the components related to the present utility model are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0019] Embodiment 1:

[0020] As Figure 1As shown in the figure, a pneumatic pressure roller structure includes a pressure roller 1 and a conductive roller 2. Conductive slip rings 7 are respectively arranged at both ends of the conductive roller 2. The conductive roller 2 is rotationally connected to an external structure through the conductive slip rings 7, and the external structure supports the conductive roller 2 and controls the rotation of the conductive roller 2; the pressure roller 1 is arranged opposite to the conductive roller 2, and an electrolytic copper foil is adapted to pass between the pressure roller 1 and the conductive roller 2; it further includes a cylinder 3 and a solenoid valve 4 for controlling the distance between the pressure roller 1 and the conductive roller 2; the cylinder 3 is fixedly arranged at the end of the pressure roller 1, and at least one end of the pressure roller 1 is provided with the cylinder 3; in this example, cylinders 3 are arranged at both ends of the pressure roller 1. The action of the cylinder 3 is used to control the pressure roller 1 to approach or move away from the conductive roller 2, thereby controlling the pressing force between the pressure roller 1 and the conductive roller 2; the fixed end of the cylinder 3 is connected to an external support structure, and the movable end of the cylinder 3 is rotationally connected to the pressure roller 1 to realize the control of the displacement of the pressure roller 1; the first air port and the second air port of the cylinder 3 are respectively connected to the solenoid valve 4, and the solenoid valve 4 controls the expansion and contraction of the cylinder 3; the solenoid valve 4 is also connected to an external air supply device.

[0021] The solenoid valve 4 adopts a two-position five-way solenoid valve 4; the two-position five-way solenoid valve 4 is provided with five air vents, including port A, port B, port R, port P and port S. Among them, port A and port B are used to connect to the cylinder 3, and form a circulating inlet and outlet air with the first air port and the second air port of the cylinder 3. Port R and port S are used to discharge the gas in the cylinder 3 to the outside, and port P is used to access the gas introduced into the cylinder 3; in this example, a pilot two-position five-way solenoid valve 4 is adopted, which has two valve bodies. Through the switching of the two valve bodies, the switching of the inlet and outlet air of port A and port B is realized. The A port and the B port at the air outlet end of the solenoid valve 4 are respectively connected to the first air port and the second air port of the cylinder 3; the air vents of the solenoid valve 4 connected to the first air port and the second air port of the two cylinders 3 are the same, that is, the first air ports of the two cylinders 3 are both connected to port A or port B, and the second air ports of the two cylinders 3 are both connected to the remaining air vents of port A and port B.

[0022] A regulating valve 5 is further arranged between the first air port and the second air port of the cylinder 3 and the solenoid valve 4. The regulating valve 5 is used to control the gas flow rate entering the cylinder 3 via the solenoid valve 4 and the gas flow rate flowing from the cylinder 3 to the solenoid valve 4.

[0023] The solenoid valve 4 is also connected to a control system. The control system is used to control the energization and de-energization of the solenoid valve 4, thereby realizing the automatic control of the pressing force between the pressure roller 1 and the conductive roller 2.

[0024] A pressure reducing valve 6 is further included. The intake end of the solenoid valve 4 is connected to an external air supply device through the pressure reducing valve 6. The pressure reducing valve 6 directly controls the gas flow rate of the external air supply device entering the solenoid valve 4, limits the upper limit of the intake speed of the cylinder 3, and prevents the pressing force between the pressure roller 1 and the conductive roller 2 from increasing suddenly due to too fast inflation of the cylinder 3, resulting in extrusion deformation and damage to both of them.

[0025] During the implementation process, by arranging a cylinder 3 at the end of the pressure roller 1, the clamping force between the pressure roller 1 and the conductive roller 2 is pneumatically controlled, avoiding the randomness of manual adjustment and improving the consistency of the quality of the electrolytic copper foil product; by arranging a regulating valve 5, the speed of the gas entering and flowing out of the cylinder 3 is controlled, thereby controlling the telescopic speed of the cylinder 3 and the adjustment of the pressing force; by arranging a pressure reducing valve 6, the upper limit of the air intake speed of the cylinder 3 is restricted.

[0026] The above description is only a specific example of the present utility model and does not constitute any limitation to the present utility model. Obviously, for professionals in the field, after understanding the content and principle of the present utility model, various modifications and changes in form and details may be made without departing from the principle and structure of the present utility model. However, these corrections and changes based on the idea of the present utility model are still within the scope of protection of the claims of the present utility model.
