Description

Technical Field

[0001] This application relates to the field of electrode production technology, and in particular to air flotation rollers and coating equipment. Background Technology

[0002] Electrodes are a crucial component of lithium batteries. During electrode production, a paste is typically coated onto both the top and bottom surfaces of the electrode. For these double-sided coated sheets, a non-contact air-bearing roller is commonly used for transport. The air-bearing roller has air outlets on its outer periphery, allowing high-pressure airflow to blow out and lift the electrode sheet. As the sheet moves under traction, it balances the force of the high-pressure airflow from the air-bearing roller's outlets, achieving non-contact, suspended movement of the sheet.

[0003] In related technologies, air flotation rollers are all structurally fixed. The air outlet width of the air flotation roller in its own axial direction cannot be adjusted according to the actual width of the product. The corresponding air flotation roller can only be customized according to the application conditions of different products. This cannot meet the customer's compatibility requirements for multi-size products, increases production costs, and affects the product production cycle. Utility Model Content

[0016] The technical solution provided in this application may include the following beneficial results:

[0017] This application provides a first adjustment mechanism within the roller body, comprising at least two first adjustment members. Exemplarily, two first adjustment members are used as an example for explanation. The two first adjustment members are spaced apart within the roller body and can be arc-shaped structures abutting against the inner wall surface of the roller body, enclosing the inner cavity of the roller body into an exhaust chamber. The exhaust chamber is composed of the two first adjustment members and the inner wall surface of the roller body located between the two first adjustment members. The air outlet is located within the exhaust chamber, allowing the gas discharged from the air outlet to fill the exhaust chamber before being discharged. Therefore, only the exhaust area communicating with the exhaust chamber can discharge gas. In this embodiment, the two first adjustment members can move along the axial direction of the roller body 1, increasing or decreasing the distance between the two first adjustment members, thereby changing the size of the exhaust chamber and simultaneously changing the size of the area on the roller surface communicating with the exhaust chamber in the axial direction of the roller body. When the area of ​​the air outlet holes on the roller surface communicating with the air outlet chamber in the axial direction of the roller body increases, the air outlet width of the air-bearing roller increases accordingly; when the area of ​​the air outlet area on the roller surface communicating with the air outlet chamber in the axial direction of the roller body decreases, the air outlet width of the air-bearing roller decreases accordingly. Therefore, this application can adjust the air outlet width of the air-bearing roller by moving the first adjusting member in the axial direction of the roller body, thereby adapting to the transportation of products of different widths, meeting customers' compatibility requirements for multi-size products, reducing production costs, and shortening the product production cycle.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] In related technologies, air flotation rollers are all structurally fixed. The air outlet width of the air flotation roller in its own axial direction cannot be adjusted according to the actual width of the product. The corresponding air flotation roller can only be customized according to the application conditions of different products. This cannot meet the customer's compatibility requirements for multi-size products, increases production costs, and affects the product production cycle.

[0033] To address the aforementioned issues, this application provides a floating roller that can adjust the air outlet width of the air-floating roller according to the actual width of the product, thereby meeting customers' compatibility requirements for multi-size products, reducing production costs, and shortening the product production cycle.

[0034] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0035] Figure 1 This is a schematic diagram of the external structure of the air flotation roller shown in an embodiment of this application; Figure 2 This is a schematic diagram of the internal structure of the air flotation roller shown in the embodiments of this application; Figure 3 This is another internal structure diagram of the air flotation roller shown in the embodiments of this application.

[0036] See Figure 1 , Figure 2 and Figure 3This application provides an air flotation roller, including a roller body 1 and a first adjustment mechanism 2. The roller body 1 has an air outlet 10 inside, and an air outlet area 12 is provided on the roller surface 11 of the roller body 1. The first adjustment mechanism 2 includes at least two first adjustment members 20 movably disposed inside the roller body 1. The at least two first adjustment members 20 enclose the inside of the roller body 1 to form an air outlet chamber 13, and the air outlet 10 is located in the air outlet chamber 13. The at least two first adjustment members 20 can move along the axial direction of the roller body 1 to adjust the opening and closing of the air outlet area 12 on the roller surface 11 in the axial direction of the roller body 1 and the air outlet 10.

[0037] In this embodiment, the roller body 1 can be a hollow cylinder. The roller body 1 may include a base, a shell, and two end caps, which are connected to form the cylindrical roller body. External high-pressure gas can be discharged into the inner cavity of the roller body 1 through the air outlet 10, and then discharged through the air outlet area 12 on the roller surface 11, blowing up the substrate or other sheets on the roller surface 11. When the sheets move under the traction force, they will be balanced with the wind force of the high-pressure airflow blown out by the air outlet area 12 of the roller surface 11, realizing the non-contact movement of the suspended sheets.

[0038] In this embodiment, the air outlet region 12 can be a porous structure, or the material used for the air outlet region 12 can be a material that can uniformly outlet air, such as porous media, graphite rollers, sintered mesh, etc. This application does not limit this.

[0039] This embodiment of the application also provides a first adjustment mechanism 2 within the roller body 1. The first adjustment mechanism 2 is used to adjust the air outlet width (air outlet length along the axial direction of the roller body 1) of the air flotation roller. The first adjustment mechanism 2 includes at least two first adjustment members 20. Exemplarily, two first adjustment members 20 are used as an example for explanation. The two first adjustment members 20 are spaced apart within the roller body 1 and can be arc-shaped structures that abut against the inner wall surface of the roller body 1, enclosing the inner cavity of the roller body 1 to form an air outlet chamber 13. The air outlet chamber 13 is composed of the two first adjustment members 20 and the inner wall surface of the roller body 1 located between the two first adjustment members 20. The air outlet 10 is located within the air outlet chamber 13, so that the gas discharged from the air outlet 10 fills the air outlet chamber 13 and then discharges from the air outlet chamber 13. Therefore, only the air outlet area 12 connected to the air outlet chamber 13 can discharge gas. In this embodiment, the two first adjusting members 20 can move along the axial direction of the roller body 1, allowing the interval between the two first adjusting members 20 to increase or decrease, thereby changing the size of the air outlet chamber 13 and simultaneously changing the size of the area on the roller surface 11 that connects the air outlet area 12 in the axial direction of the roller body 1 with the air outlet chamber 13. When the area on the roller surface 11 that connects the air outlet area 12 in the axial direction of the roller body 1 with the air outlet chamber 13 increases, the air outlet width of the air-bearing roller increases accordingly; when the area on the roller surface 11 that connects the air outlet area 12 in the axial direction of the roller body 1 with the air outlet chamber 13 decreases, the air outlet width of the air-bearing roller decreases accordingly. Therefore, in this embodiment, the air outlet width of the air-bearing roller can be adjusted by moving the first adjusting members 20 in the axial direction of the roller body 1, thereby adapting to the transportation of products of different widths, meeting customers' compatibility requirements for multi-size products, reducing production costs, and shortening the product production cycle.

[0040] As an optional embodiment, see Figure 2 and Figure 3 The first adjustment mechanism 2 further includes a movable seat 21 movably disposed inside the roller body 1. The movable seat 21 has a movement direction including movement along the circumferential direction of the roller body 1. The first adjustment member 20 is movably disposed on the movable seat 21 and can move along the axial direction of the roller body 1 on the movable seat 21, and can move along the circumferential direction of the roller body 1 under the drive of the movable seat 21, so as to adjust the opening and closing of the air outlet area 12 on the roller surface 11 in the circumferential direction of the roller body 1 and the air outlet 10. At least two first adjustment members 20, the movable seat 21 located between the at least two first adjustment members 20 and the inner wall surface of the roller body 1 enclose an air outlet chamber 13.

[0041] In this embodiment, the movement direction of the first adjusting member 20 on the movable seat 21 includes movement along the axial and circumferential directions of the roller body 1. The movement of the first adjusting member 20 along the circumferential direction of the roller body 1 can be generated by the rotation of the movable seat 21. The top surface of the exhaust chamber 13 can be the inner wall surface of the roller body 1 located between at least two first adjusting members 20, the opposite side walls can be the inner wall surface of the movable seat 21 located between at least two first adjusting members 20, and the opposite end faces can be the opposing wall surfaces of at least two first adjusting members 20. These wall surfaces together enclose and form the exhaust chamber 13, ensuring that the gas discharged from the air outlet 10 only fills the exhaust chamber 13 and does not enter other internal spaces of the roller body 1.

[0042] As an optional embodiment, see Figure 2 , Figure 3 and Figure 4 The air flotation roller also includes a second adjustment mechanism 3, which includes a second adjustment member 30. One end of the second adjustment member 30 is connected to the movable seat 21, and the other end is slidably mounted on the roller body 1 and can move along the circumferential direction of the roller body 1 to drive the movable seat 21 to move, while adjusting the angle of the first adjustment member 20 in the circumferential direction of the roller body 1.

[0043] In this embodiment, the second adjustment mechanism 3 is used to adjust the air outlet angle of the air flotation roller to adapt to products with different transport directions.

[0044] Exemplarily, the second adjustment mechanism 3 of this application embodiment includes a second adjustment member 30. One end of the second adjustment member 30 is fixedly connected to the movable seat 21, and the other end is slidably disposed on the roller body 1 and can move along the circumferential direction of the roller body 1. When the second adjustment member 30 moves along the circumferential direction of the roller body 1, it will drive the movable seat 21 to rotate, thereby also driving the first adjustment member 20 to move along the circumferential direction of the roller body 1, thereby changing the size of the range of the air outlet area 12 and the air outlet chamber 13 communicating in the circumferential direction of the roller body 1 on the roller surface 11. When the range of the air outlet area 12 and the air outlet chamber 13 communicating in the circumferential direction of the roller body 1 on the roller surface 11 increases, the air outlet angle of the air flotation roller increases accordingly; when the range of the air outlet area 12 and the air outlet chamber 13 communicating in the circumferential direction of the roller body 1 on the roller surface 11 decreases, the air outlet angle of the air flotation roller decreases accordingly. Therefore, in this embodiment of the application, the second adjusting member 30 can drive the movable seat 21 and the first adjusting member 20 to move along the circumferential direction of the roller body 1, thereby adjusting the air outlet angle of the air flotation roller, so as to adapt to the transportation of products with different covering angles (or transportation directions), meet the customer's compatibility requirements for products with different covering angles (or transportation directions), reduce production costs, and shorten the product production cycle.

[0045] As a preferred embodiment, see Figure 3A first arc-shaped groove 14 is provided on the end face of the roller body 1, and the second adjusting member 30 is slidably disposed in the first arc-shaped groove 14.

[0046] In this embodiment, the first arc-shaped groove 14 is disposed on the end face of the roller body 1, which can avoid affecting the air outlet area 12 on the roller surface 11. Moreover, the first arc-shaped groove 14 can be an arc-shaped structure with the center of the end face of the roller body 1 as the center. When the second adjusting member 30 moves along the arc trajectory of the first arc-shaped groove 14 in the first arc-shaped groove 14, it can drive the first adjusting member 20 to rotate in the axial direction of the roller body 1.

[0047] As a preferred embodiment, see Figure 2 , Figure 3 and Figure 5 The first adjusting member 20 includes two partitions 200 that can rotate relative to each other, and the two partitions 200 are arc-shaped structures that abut against the inner wall of the roller body 1.

[0048] In this embodiment, the two partitions 200 can be fan-shaped structures, with both sides and the bottom connected to the movable seat 21, and the top end being an arc-shaped structure that abuts against the inner wall of the roller body 1, thereby preventing gas in the air outlet chamber 13 from leaking into other internal spaces of the roller body 1.

[0049] As a preferred embodiment, see Figure 4 and Figure 5 The movable seat 21 includes two movable plates 210 arranged along the axial direction of the roller body 1 and movably connected to each other. The second adjusting member 30 is connected to the movable plates 210 and is used to drive the two movable plates 210 to open and close. Two partitions 200 are respectively arranged on the two movable plates 210, and one of the partitions 200 has a clamping groove 201, and the other partition 200 is embedded in the clamping groove 201 and can slide in the clamping groove 201 under the drive of the second adjusting member 30.

[0050] In this embodiment, the connection interface of the two movable plates 210 can be located on the central axis of the roller body 1, and the two movable plates 210 can be hinged to achieve opening and closing movement. The second adjusting member 30 can be connected to one of the movable plates 210 and is used to drive one of the movable plates 210 to move along the circumferential direction of the roller body 1, thereby realizing the opening and closing movement of the two movable plates 210. Two partitions 200 are respectively disposed on the two movable plates 210. When one of the movable plates 210 moves, it will simultaneously drive the partition 200 connected to the movable plate 210 to move along the circumferential direction of the roller body 1, thereby realizing the opening and closing movement of the partition 200.

[0051] The partition 200 with the groove 201 in one of the two partitions is thicker, and the other partition 200 is thinner and is adapted to the thickness of the groove 201, so that the partition 200 can slide in the groove 201 and be limited in the groove 201.

[0052] Preferably, the partition 200 with the groove 201 is the first partition and the other is the second partition. The second adjusting member 30 is connected to the movable plate 210 connected to the second partition and is used to drive the second partition to slide within the groove 201 of the first partition.

[0053] As an optional embodiment, see Figure 2 , Figure 3 and Figure 4 The first adjustment mechanism 2 also includes a drive mechanism 4, which is connected to at least two first adjustment members 20 and is used to drive the at least two first adjustment members 20 to move away from or closer to each other.

[0054] In this embodiment, a driving mechanism 4 is also provided to drive the first adjusting member 20 to move along the axial direction of the roller body 1, and simultaneously drive at least two first adjusting members 20 to move in the same or opposite directions, so as to increase or decrease the distance between at least two first adjusting members 20.

[0055] As a preferred embodiment, see Figures 2 to 5 The drive mechanism 4 includes a plurality of drive rods 40 arranged along the axial direction of the roller body 1, and a coupling 41 connecting the plurality of drive rods 40; at least one first adjusting member 20 is connected to each drive rod 40, and the two drive rods 40 connected by the coupling 41 rotate in opposite directions.

[0056] For example, this application embodiment uses two first adjusting members 20 and two driving rods 40. The two driving rods 40 are connected by a coupling 41, and each of the two driving rods 40 is connected to a first adjusting member 20. The two driving rods 40 can be lead screws with opposite thread directions. When one lead screw rotates, it drives the other lead screw to rotate in the opposite direction via the coupling 41. Therefore, when the two lead screws rotate, they can drive the two first adjusting members 20 to move closer or further apart along the axial direction of the lead screws.

[0057] As a preferred embodiment, see Figure 6 A second arc-shaped groove 15 is provided on the end face of the roller body 1. A sliding member 42 is connected to the end of the drive rod 40 away from the first adjusting member 20. The sliding member 42 extends out of the second arc-shaped groove 15 and can drive the drive rod 40 to slide in the second arc-shaped groove 15 to adjust the opening and closing angle of the first adjusting member 20 in the circumferential direction of the roller body 1. The sliding member 42 can also drive the drive rod 40 to rotate.

[0058] In this embodiment, the second arc-shaped groove 15 is disposed on the end face of the roller body 1, which can avoid affecting the air outlet area 12 on the roller surface 11. Moreover, the second arc-shaped groove 15 can be an arc-shaped structure with the center of the end face of the roller body 1 as the center. When the drive rod 40 moves along the arc trajectory of the second arc-shaped groove 15, it can drive the first adjusting member 20 to rotate along the circumferential direction of the roller body 1.

[0059] In this embodiment, the slider 42 may include a handwheel and a slide rod connected to the handwheel. By rotating the handwheel, the drive rod 40 is rotated, and by moving the slide rod, it slides within the second arc-shaped groove 15, thereby causing the first adjusting member 20 to rotate along the circumferential direction of the roller body 1.

[0060] As an optional embodiment, see Figure 2 and Figure 3 The air flotation roller also includes an air inlet pipe 5, which is disposed inside the roller body 1 along the axial direction of the roller body 1, and at least one end of the air inlet pipe 5 extends to the outside of the roller body 1 to form an air inlet; and the portion of the air inlet pipe 5 located in the air outlet chamber 13 is provided with an air outlet 10.

[0061] In this embodiment, the first adjusting member 20 is movably disposed on the intake pipe 5 and can move along the axial direction of the intake pipe 5. Preferably, the movable seat 21 is rotatably disposed on the intake pipe 5 and can rotate about the axial direction of the intake pipe 5. More preferably, the connecting ends of the two movable plates 210 are disposed on the intake pipe 5 and are respectively hinged to the intake pipe 5.

[0062] Both ends of the air inlet pipe 5 extend beyond the end face of the roller body 1 to form an air inlet. Threads can be provided on the air inlet to connect the air inlet pipe 5 to an external air intake device. The gas input into the air inlet pipe 5 through the external air intake device can be discharged into the air outlet chamber 13 through the air outlet 10.
