[0002] The surface treatment machine is the core equipment for copper foil surface treatment, and the pressure roller plays a key role in surface treatment. Developing advanced and high-precision tension control systems, improving the accuracy and stability of the pressure roller adjustment mechanism, improving the level of automation, and solving the problems of easy electric shock, tearing, wrinkling, and deviation in surface treatment production are urgent needs for the current production of high-end ultra-thin copper foil. In the entire surface treatment process, the stability of the pressure roller plays a very important role in the quality of the copper foil. Each liquid inlet roller and liquid outlet roller in the entire production line has a pressure roller to cooperate with the solution on the surface of the copper foil. The extrusion angle and pressing force of the pressure roller need to be precisely controlled. Too large or too small a pressing force will affect the effect of the surface treatment, and ultimately affect the quality of the copper foil surface treatment.

[0003] The existing clamping device can only adjust one pressure roller at a time. Frequent replacement of pressure rollers is time-consuming and labor-intensive, and the operating efficiency is low. Therefore, according to the actual process production requirements, it is urgent to design and research a surface treatment pressure roller base and adjustment mechanism that meets the actual working conditions and is more efficient. This has high academic and application value for improving the efficiency of copper foil surface treatment products and improving the competitiveness of the copper foil surface treatment machine industry.

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer and more understandable, the technical solution of the utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] like Figure 1-Figure 4 As shown, the utility model provides a roller base lifting and adjusting mechanism for a surface treatment machine, comprising a base 1 and two scissor arm adjustment structures, the two scissor arm adjustment structures are centrally symmetrically mounted on the base 1, the scissor arm adjustment structures comprise scissor arms 5, a height adjustment assembly and a bearing seat unit, the scissor arms 5 are rotatably mounted on the base 1, the bearing seat unit is mounted on the scissor arms 5, and the height adjustment assembly is mounted on the base 1 to drive the scissor arms 5 to rotate relative to the base 1, thereby changing the height of the bearing seat unit, thereby making the two rollers at the same horizontal height.

[0022] The overall device is located between the liquid inlet roller and the liquid outlet roller. The two bearing seat units correspond to two pressure rollers respectively, one of which has a diameter of 150 mm and the other has a diameter of 135 mm. During operation, the two pressure rollers are respectively installed on the two bearing seat units, and then the height of the pressure rollers can be changed by adjusting the height of the scissor arm 5 through the height adjustment component, so that the two pressure rollers are finally at the same horizontal height.

[0023] The height adjustment assembly includes an L-shaped mounting plate 36 and a height adjustment bolt 28. The L-shaped mounting plate 36 is fixedly mounted on the base 1. The height adjustment bolt 28 is threadedly inserted into the L-shaped mounting plate 36. The height adjustment bolt 28 contacts the bottom edge of the scissor arm 5.

[0024] Turn the height adjustment bolt 28. Since the height adjustment bolt 28 and the L-shaped mounting plate 36 are threadedly matched, the height adjustment bolt 28 can move up and down relative to the L-shaped mounting plate 36 when it rotates. When the height adjustment bolt 28 rises, it can support the scissor arm 5, so that the scissor arm 5 rotates relative to the base 1, thereby changing the height of the bearing seat unit and adjusting the height of the pressure roller.

[0025] The bearing seat unit includes a base plate 12, a bearing seat 15 and a horizontal adjustment component. The base plate 12 is fixedly mounted on the scissor arm 5. The bearing seat 15 is slidably mounted on the base plate 12 and fixed by a mounting bolt 18. The horizontal adjustment component is used to drive the bearing seat 15 to slide on the base plate 12. The horizontal adjustment component includes two adjustment plates 13, two horizontal adjustment bolts 23 and two horizontal adjustment nuts 24. The two adjustment plates 13 are fixedly connected to the base plate 12 and are located on both sides of the bearing seat 15. The two horizontal adjustment bolts 23 are respectively inserted into the two adjustment plates 13 by threaded fitting, and the two horizontal adjustment nuts 24 are respectively sleeved on the two horizontal adjustment bolts 23 by threaded fitting.

[0026] The bearing seat 15 is divided into two parts, the upper and lower parts, which are connected and fixed by fastening bolts. When installing the pressure roller, you need to first unscrew the fastening bolts, then lift the upper part of the bearing seat 15, place the roller of the pressure roller on the lower part of the bearing seat 15, then put down the lifted upper part of the bearing seat 15, and then tighten the fastening bolts.

[0027] After the pressure roller is installed, the staff needs to loosen the installation bolt 18 first, and then loosen the horizontal adjustment nut 24, and then rotate the horizontal adjustment bolt 23. Since the horizontal adjustment bolt 23 and the adjustment plate 13 are threaded, the horizontal adjustment bolt 23 can move relative to the adjustment plate 13 when rotating, and the adjustment plate 13 is arranged on both sides of the bearing seat 15. Therefore, rotating the horizontal adjustment bolt 23 can make the horizontal adjustment bolt 23 approach or move away from the bearing seat 15, thereby adjusting the horizontal position of the bearing seat 15, that is, the pressure roller. After the adjustment is completed, tighten the horizontal adjustment nut 24 again to fix it.

[0028] Through the above-mentioned height adjustment and horizontal adjustment of the pressure roller and the deadweight of the pressure roller and the scissor arm 5, the axes of the two pressure rollers and the liquid inlet roller and the liquid outlet roller are not in a straight line, but are located a certain distance to the left of the vertical center line of the liquid inlet roller and the liquid outlet roller, thereby realizing a side pressure clamping method. This clamping method can effectively squeeze out the solution on the surface of the copper foil and avoid the phenomenon of vertical lines on copper foil below 18 microns during surface treatment.

[0029] A handle 30 is fixedly connected to one end of the scissor arm 5 away from the base 1 , and the handle 30 can facilitate the staff to move the scissor arm.

[0030] A rod shaft 31 is fixedly mounted on the scissor arm 5, a support rod 32 is slidably inserted on the rod shaft 31, and a buckle 33 is inserted on the rod shaft 31 to prevent the support rod 32 from sliding out of the rod shaft 31. The function of setting the support rod 32 is to support the support rod 32 on the L-shaped mounting plate 36 when the machine is shut down or overhauled to ensure the stability of the device.

[0031] To sum up, the overall working process of the utility model is as follows: first, install the pressure roller on the bearing seat 15, and then rotate the height adjusting bolt 28 to change the height of the pressure roller so that the two pressure rollers are at the same horizontal height; loosen the mounting bolt 18 and the horizontal adjusting nut 24, rotate the horizontal adjusting bolt 23, and change the horizontal position of the pressure roller so that the pressure roller with a diameter of 150 mm contacts the left side of the liquid inlet roller, and the pressure roller with a diameter of 135 mm contacts the left side of the liquid outlet roller, and then tighten the mounting bolt 18 and the horizontal adjusting nut 24 to fix the position of the pressure roller at this time, and then loosen the height adjusting bolt 28, and use the scissor arm 5 and the weight of the pressure roller to clamp the two liquid inlet rollers and the liquid outlet rollers to finally achieve the side pressure clamping method.
