[0027] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0028] Please see Figure 1 This utility model provides an air flotation roller, including a roller assembly 1 and a shielding assembly 2. The roller assembly 1 is used to transport the electrode sheet, and the shielding assembly 2 can adjust the air outlet range of the roller assembly 1 to be suitable for the transmission of electrode sheets of different sizes.

[0029] Specifically, the roller assembly 1 includes a roller 11 and two fixing members 12, which are respectively connected to both ends of the roller 11. At least one end of the roller 11 is provided with an air inlet 110 communicating with its inner cavity. The side wall of the roller 11 is provided with an air outlet side 111. Gas is injected into the roller 11 through the air inlet 110, so that an airflow is formed on the air outlet side 111 to transport the electrode sheet in a non-contact manner. The shielding assembly 2 includes at least two fixed shafts 21 and several shielding cloths 22. The two ends of the fixed shafts 21 are respectively mounted on the two fixing members 12. The two ends of the shielding cloths 22 are detachably connected to the two fixed shafts 21 respectively, and the shielding cloths 22 cover the air outlet side 111. Since the two ends of the shielding cloth 22 are detachably connected to the fixed shaft 21, different numbers of shielding cloths 22 can be connected to the fixed shaft 21 according to actual needs. The air outlet side 111 of the roller 11 can generate airflow and transport the electrode sheet in a suspended manner. Since the shielding cloth 22 covers the air outlet side 111, the shielding area can be adjusted by adjusting the number of shielding cloths 22, thereby adjusting the air outlet range of the air flotation roller, improving the applicability of the air flotation roller, so that the air flotation roller can transport electrode sheets of different widths and reduce production costs.

[0030] Please see Figure 2 Furthermore, the fixed shaft 21 includes a first pressure rod 23 and a second pressure rod 24. The shielding cloth 22 is clamped between the first pressure rod 23 and the second pressure rod 24. The first pressure rod 23, the second pressure rod 24 and the shielding cloth 22 are connected by a pin 211. The pin 211 passes through the first pressure rod 23, the shielding cloth 22 and the second pressure rod 24. The pin 211 can play a positioning role and prevent the shielding cloth 22 from retracting.

[0031] Please see Figure 3 The second pressure rod 24 has a receiving groove 212 on the side facing the first pressure rod 23. A magnet 213 is placed in the receiving groove 212. The first pressure rod 23 is made of magnetic metal. In this embodiment, the first pressure rod 23 is made of stainless steel, which is corrosion-resistant and more durable. The second pressure rod 24 is provided with a first screw 214, which is screwed to the magnet 213. The first screw 214 is used to fix the magnet 213 to the second pressure rod 24. The magnet 213 can be magnetically attracted to the first pressure rod 23. The shielding cloth 22 is flattened between the magnet 213 and the first pressure rod 23, and the shielding cloth 22 is further fixed by the magnetic attraction.

[0032] After the end of the shielding cloth 22 passes through the gap between the first pressure rod 23 and the second pressure rod 24, it is folded outward to form a folded part 221. The folded part 221 covers the second pressure rod 24 and is fixed to the second pressure rod 24 by the second screw 222, which further fixes the shielding cloth 22 to the fixed shaft 21 to prevent the shielding cloth 22 from moving.

[0033] In this embodiment, the fixed shaft 21 includes a first pressure rod 23 and several second pressure rods 24. The first pressure rod 23 is provided with a connecting groove 218. The several second pressure rods 24 are arranged in a straight line and connected in the connecting groove 218. The several second pressure rods 24 are used to clamp several shielding cloths 22. When disassembling the shielding cloth 22, the corresponding second pressure rod 24 can be removed from the first pressure rod 23. The remaining second pressure rods 24 remain stationary for easy use.

[0034] Please see Figure 4-5 The roller 11 includes a guide pipe 112 and a roller 113. The guide pipe 112 is located inside the roller 113 and has several guide grooves 114. The roller 113 has several air outlet holes (not shown in the figure). An inner baffle 115 is provided on one side of the inner wall of the roller 113, and the other side is the air outlet side 111. A sintered mesh 116 is provided on the inner wall of the roller 113, located on the air outlet side 111. Air is supplied to the guide pipe 112 and enters the roller 113 through the guide grooves 114. The inner baffle 115 is tightly attached to the inner wall of the roller 113, blocking the outflow of gas and ensuring the required air outlet range on the surface of the roller 113. The sintered mesh 116 can filter the gas output from the air outlet side 111 and control the airflow distribution to ensure airflow uniformity.

[0035] Furthermore, the outer wall of the roller 113 is provided with two outer baffles 117. Both outer baffles 117 are mounted on the fixing member 12, and the two outer baffles 117 are located on both sides of the inner baffle 115. The outer baffles 117 are close to the outer wall of the roller 113 and are used to supplement the blocking range of the inner baffle 115. The range of the air outlet side 111 can be further adjusted by setting the outer baffles 117.

[0036] In this embodiment, the fixing member 12 includes a fixing plate 121 and a mounting block 122. The fixing plate 121 is mounted on the end face of the roller 113. The mounting block 122 includes a first connecting portion 123 and a second connecting portion 124, which are connected in an L-shape. The first connecting portion 123 is fixed to the surface of the fixing plate 121 by a third screw 126. Please refer to [link to previous section]. Figure 6 The end of the outer baffle 117 is clamped between the outer peripheral surface of the fixing plate 121 and the second connecting part 124, and the second connecting part 124 is provided with a set screw 127, which is used to abut against the end of the baffle to ensure the firmness of the baffle installation.

[0037] Please see Figure 6 The first connecting portion 123 extends in a direction away from the fixing piece 121, and a third connecting portion 125 is provided. Please refer to [link / reference]. Figure 7The third connecting part 125 is provided with a mounting hole 128. The fixed shaft 21 passes through the mounting hole 128 and is installed on the third connecting part 125. Specifically, the end of the first pressure rod 23 passes through the mounting hole 128. The third connecting part 125 facilitates the installation of the fixed shaft 21.

[0038] In this embodiment, the structure for movably connecting the fixed shaft 21 and the mounting hole 128 is as follows: a locking screw (not shown in the figure) is provided on the third connecting part 125, and a notch 129 is provided on the edge of the mounting hole 128 extending towards the third connecting part 125. The locking screw passes through the notch 129 and is used to adjust the width of the notch 129, thereby adjusting the size of the mounting hole 128. By rotating the locking screw, the mounting hole 128 and the fixed shaft 21 can be clearance-fitted or interference-fitted, thereby realizing the rotation or fixation of the fixed shaft 21.

[0039] Please see Figure 6-7 One end of the fixed shaft 21 is provided with a connecting hole 215, the axis of the connecting hole 215 is perpendicular to the axis of the fixed shaft 21, and a connecting shaft 216 passes through the connecting hole 215. A knob 217 is fixedly connected to the connecting shaft 216. Specifically, the connecting hole 215 is located on the first pressure rod 23. Rotating the locking screw makes the fixed shaft 21 and the mounting hole 128 fit with a clearance. By rotating the knob 217, the fixed shaft 21 can be rotated to tighten both ends of the shielding cloth 22 to prevent air leakage on the air outlet side 111 located at the shielding cloth 22.
