Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to an adjustable air nozzle with slit-type air outlet. Background Technology

[0002] Due to the increasing demand for improved lithium battery performance, substrate thickness is decreasing and width specifications are becoming more diverse. Coating machine production lines can coat substrates of different widths, but the length of the nozzles is designed according to the width of the machine model and is not adjustable. When the substrate width is short, the air outlet length of the nozzle slit will be too long. Under the action of tension and air pressure, when the substrate passes through the oven, due to its thinness and small width, and the excessively long air outlet length of the nozzle slit, the substrate is disturbed by the hot air flow field, causing severe edge shaking in the TD direction, which affects the coating effect.

[0003] The existing method is to adjust the air outlet range of the air outlet by applying tape to the air outlet seam, but this method is inefficient and time-consuming.

[0004] In view of this, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

[0026] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[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 / linkages 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. The various technical features in this utility model can be combined interactively without contradicting each other.

[0028] Reference Figures 1 to 4 This invention provides an adjustable slit-type air nozzle for use in coating machine production lines. By controlling the air outlet range of the nozzle, it can adapt to substrates of different widths. It includes a nozzle body 1 with an air inlet 11 and an air outlet slit 12. The nozzle body 1 also includes a guide cavity 14 and other conventional structures. The air inlet 11, guide cavity 14, and air outlet slit 12 are sequentially connected according to the airflow direction. When the nozzle body 1 performs drying and blowing operations on the electrode sheets, the air blown by the external fan enters the guide cavity 14 through the air inlet 11, converges within the guide cavity 14, and is then discharged through the air outlet slit 12 and blown onto the surface of the electrode sheets.

[0029] Reference Figures 2 to 4 The air outlet slit 12 is designed as a long, narrow opening, and the length direction of the overall structure of the nozzle body 1 is consistent with the length direction of the air outlet slit 12. A slit adjustment assembly 2 is disposed on the nozzle body 1 to close part of the air outlet slit 12, thereby adjusting the length of the air outlet slit 12 so that the nozzle body 1 can adapt to electrode sheets of different widths, thus ensuring the quality of electrode sheet drying and forming. The slit adjustment assembly 2 is disposed at both ends of the length direction of the nozzle body 1, wherein the length direction of the nozzle body 1 is perpendicular to the electrode sheet conveying direction. The slit adjustment assembly 2 includes a roller 21 and a flexible shielding part 22. The roller 21 is disposed at the end of the nozzle body 1, and the flexible shielding part 22 is wound around the roller 21, wherein the flexible shielding part 22 can extend or retract to close part of the air outlet slit 12. A drive assembly 3 is disposed on the nozzle body 1, and the drive assembly 3 is connected to the flexible shielding part 22 to drive the flexible shielding part 22 to extend or retract, thereby covering part of the air outlet slit 12.

[0030] In this embodiment, the nozzle body 1 has two air outlet slits 12 symmetrically opened on both sides in the width direction. Correspondingly, the slit adjustment components 2 on the two air outlet slits 12 are symmetrically arranged to adjust the length of the two air outlet slits 12 respectively.

[0031] Furthermore, mounting seats 13 are provided at both ends of the nozzle body 1 along its length, and the roller 21 is mounted on the mounting seats 13. Specifically, the mounting seats 13 are provided with set screws 131, and the roller 21 is connected and fixed to the mounting seats 13 by the set screws 131. In other embodiments, the roller 21 can also be connected to the mounting seats 13 by welding or other methods, which is not the only limitation here.

[0032] In some embodiments, the flexible shielding part 22 is a constant force spring 221, which is sleeved on the roller 21, and the free end of the constant force spring 221 is connected to the drive assembly 3. The drive assembly 3 can drive the constant force spring 221 to extend or retract. The constant force spring 221 is usually made of a thin and wide metal strip (such as stainless steel) and rolled into a spiral shape. When the constant force spring 221 extends, the stress distribution inside it changes, thereby generating a constant force output. Within a certain extension or compression stroke, the constant force spring 221 can provide an almost constant output, and the force it generates during extension or compression does not change significantly with the displacement. When a pulling force is applied to the free end of the constant force spring 221, it can be driven to extend. When the external force is removed, the constant force spring 221 will automatically retract.

[0033] Reference Figure 3 and Figure 4In some embodiments, the drive assembly 3 includes a rotating shaft 31, a first solid wire 32, a second solid wire 33, and a steering wheel 35. The rotating shaft 31 is rotatably connected to one end of the nozzle body 1, and the steering wheel 35 is located at the end of the nozzle body 1 away from the rotating shaft 31. One end of the first solid wire 32 is fixedly connected to the rotating shaft 31, and the other end passes through the steering wheel 35 and is then fixedly connected to the free end of a constant force spring 221 located at the end of the nozzle body 1 near the rotating shaft 31. When the rotating shaft 31 is rotated to wind up the first solid wire 32, the first solid wire 32 pulls the constant force spring 221 to extend it, thereby blocking part of the air outlet slit 12 and narrowing its air outlet range. When the rotating shaft 31 is rotated to unwind the first solid wire 32, the constant force spring 221 retracts under its own elastic force until the first solid wire 32 is taut. One end of the second solid wire 33 is fixedly connected to the rotating shaft 31, and the other end is fixedly connected to the free end of the constant force spring 221 located near the steering wheel 35 on the nozzle body 1. When the rotating shaft 31 is rotated to wind up the second solid wire 33, the second solid wire 33 pulls the constant force spring 221 to extend it; when the rotating shaft 31 is rotated to unwind the second solid wire 33, the constant force spring 221 retracts under its own elastic force until the second solid wire 33 is taut. With this configuration, the constant force springs 221 at both ends of the nozzle body 1 can be adjusted simultaneously by rotating the shaft 31 on one side, causing them to move in opposite or opposite wind directions at the same time, thereby adjusting the air outlet range of the air outlet slit 12.

[0034] In this embodiment, the free end of the constant force spring 221 has a spring through hole. The first solid wire 32 and the second solid wire 33 are respectively tied to the spring through holes of the corresponding constant force spring 221 to achieve connection and fixation with the constant force spring 221. The drive assembly 3 also includes a positioning shaft 36, which is fixedly installed on the mounting base 13 and parallel to the rotating shaft 31. One end of the first solid wire 32 is wound and fixed on the rotating shaft 31. After being turned by the positioning shaft 36, it extends along the length direction of the nozzle body 1, then turns again after passing around the steering wheel 35, and then connects to the spring through hole of the corresponding constant force spring 221. Similarly, one end of the second solid wire 33 is wound and fixed on the rotating shaft 31. After being turned by the positioning shaft 36, it extends along the length direction of the nozzle body 1 and then connects to the spring through hole of the corresponding constant force spring 221. The positioning shaft 36 is used to position the first solid line 32 and the second solid line 33, ensuring that the constant force spring 221 is evenly stressed and reducing the possibility that uneven stress on one side of the constant force spring 221 may affect the sealing effect of the air outlet slit 12. The positioning shaft 36 is provided with positioning grooves that correspond one-to-one with the first solid line 32 and the second solid line 33, so as to ensure that the first solid line 32 and the second solid line 33 do not slide relative to each other when they are wound around the positioning shaft 36.

[0035] In addition, the slit adjustment components 2 on both sides of the width direction of the nozzle body 1 are symmetrically arranged. Correspondingly, the first solid line 32 and the second solid line 33 on the rotating shaft 31 are also symmetrically arranged, which are used to connect the constant force springs 221 of the slit adjustment components 2 on both sides, so as to simultaneously control the extension and retraction of the constant force springs 221 on both sides. That is, rotating the rotating shaft 31 can simultaneously drive the four constant force springs 221 to extend or retract, thereby controlling the length of the air outlet slits 12 on both sides of the nozzle body 1.

[0036] Reference Figure 2 and Figure 3 Furthermore, a limiting component is provided on the mounting base 13 to restrict the rotation of the rotating shaft 31. When the air outlet slit 12 is adjusted to the required length, the locking limiting component restricts the rotation of the rotating shaft 31, thus fixing the lengths of the first solid line 32 and the second solid line 33. The limiting component is a clamping block 37, which is sleeved on the end of the rotating shaft 31 and fixedly connected to the mounting base 13. A locking screw 371 is threaded onto the clamping block 37. Tightening the locking screw 371 locks the clamping block 37 onto the rotating shaft 31, thereby restricting the rotation of the rotating shaft 31.

[0037] Furthermore, the rotating shaft 31 is provided with limiting grooves 311 corresponding one-to-one with the first solid wire 32 and the second solid wire 33. One end of the first solid wire 32 and the second solid wire 33 are respectively wound and fixed in the corresponding limiting grooves 311. The limiting grooves 311 limit the first solid wire 32 and the second solid wire 33 to reduce the possibility that the first solid wire 32 and the second solid wire 33 may slide relative to the rotating shaft 31 during the winding and unwinding process, thus affecting the sealing effect of the corresponding constant force spring 221 on the air outlet slit 12.

[0038] Furthermore, a knob 34 is fixedly connected to the end of the rotating shaft 31. Rotating the knob 34 can drive the rotating shaft 31 to rotate, thereby reducing the difficulty of controlling the rotating shaft 31.

[0039] Furthermore, the nozzle body 1 is provided with a guide plate 4 that is adapted to the length of the nozzle body 1, and the guide plate 4 is used to guide and support the substrate. The guide plate 4 is provided with a scale 41, wherein the numbers on the scale 41 increase from the middle to the two ends of the component. By setting the scale 41, the range of the air outlet slit 12 blocked by the slit adjustment component 2 can be accurately measured, making the adjustment of the slit adjustment component 2 more precise.

[0040] When in use, rotating the knob 34 will cause the first solid line 32 and the second solid line 33 on the rotating shaft 31 to extend or retract the constant force springs 221. By observing the scale 41 on the guide plate 4, the constant force springs 221 are brought to the expected position. Then, tightening the locking screw 371 will lock the rotating shaft 31 with the clamping block 37, thereby controlling the constant force springs 221 to remain in the predetermined position and reach the required air outlet slit 12 air outlet range. This can adapt to foil materials of different widths and improve the applicability of the nozzle.

[0041] In addition, the slot adjustment component 2 and drive component 3 of this utility model can be directly applied to existing old air nozzles to solve the problem of substrate vibration.

[0042] Example 2:

[0043] The difference between Embodiment 2 and the above embodiment lies in that the drive assembly 3 includes a solid wire and a rotating shaft 31. Two sets of drive assemblies 3 are respectively disposed at both ends of the nozzle body 1 to control the extension and retraction of the constant force springs 221 at both ends. Specifically, the two rotating shafts 31 are rotatably connected to the mounting bases 13 at both ends. One end of the solid wire in each set of drive assemblies 3 is fixedly connected to the rotating shaft 31 of that set of drive assemblies 3, and the other end is fixedly connected to the free end of the constant force spring 221 at the opposite end. When rotating the rotating shaft 31 on one side winds up the corresponding solid wire, the solid wire pulls the constant force spring 221 on the opposite side, causing it to extend and close the air outlet slit 12, thereby adjusting the air outlet range of the air outlet slit 12. When rotating the rotating shaft 31 unwinds the corresponding solid wire, the constant force spring 221 retracts under its own elastic force to reduce the closing length of the air outlet slit 12.
