[0002] With the development and maturity of lithium battery technology, the application range of lithium batteries is also expanding. A key step in the production of lithium batteries is the drying of the coated foil, a process that requires the use of an oven. The coating machine oven primarily uses hot air to heat the coating material, allowing it to dry quickly and achieve the processing purpose. It is generally composed of a hot air generator, hot air ducting, and a hot air circulation system. During operation, the hot air generator generates high-temperature hot air, which is input into the knife oven through the hot air ducting. The hot air circulation system evenly distributes the air throughout the oven, ensuring that the coating material is evenly heated.

[0003] During the use of coating equipment, the oven is contaminated with a large amount of dust due to long-term operation and operation, requiring staff to clean it regularly to prevent it from affecting the performance of the equipment. However, due to the small gap between the upper and lower air chambers in the oven, workers find it difficult to enter the oven for internal cleaning. They often need to remove the oven nozzles and then drill into the air chamber to clean it. This cleaning process is time-consuming and labor-intensive, affecting the speed of electrode production.

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] This embodiment provides a wind chamber lifting device 200 for moving the upper wind chamber 110 in the oven 100. Figure 1-2 As shown, it includes an oven 100 shell, an upper air chamber 110 and a lower air chamber are relatively arranged in the oven 100, and a gap is formed between the upper air chamber 110 and the lower air chamber.

[0035] The air chamber lifting device 200 includes a frame 10, on which a driving module 1, a wire rope 2 and a pulley module are provided; the pulley module includes at least four pulley groups 3, the pulley group 3 includes a first changing wheel 301 and a second changing wheel 302, the first changing wheel 301 is arranged horizontally, the second changing wheel 302 is arranged vertically and the second changing wheel 302 is respectively arranged at the four corners of the frame 10; at least four pulley groups 3 are respectively wound with a wire rope 2, one end of the wire rope 2 is connected to the driving end of the driving module 1, and the other end is connected to the upper air chamber 110 through the first changing wheel 301 and the second changing wheel 302 in sequence, and the driving module 1 can drive the wire rope 2 to move to lift or lower the upper air chamber 110.

[0036] When in use, the air chamber lifting device 200 is set on the top of the oven 100, connected to the upper air chamber 110 inside the oven 100 through the wire rope 2, and lifts it.

[0037] Specifically, such as Figure 3 As shown, the frame 10 is formed into an "I" shape, consisting of two horizontal mounting beams and one vertical mounting beam. The drive module 1 is mounted on the vertical mounting beam, and the pulley module is mounted on the horizontal mounting beam. The pulley module includes at least four pulley blocks 3, preferably four. The "I" shape frame 10 is easy to install. Furthermore, mounting the drive assembly on the vertical mounting beam makes it easier to maintain the rising speed of the ropes at both ends during the rope extension process, thus ensuring greater stability of the wind chamber during the lifting process.

[0038] Please refer to Figure 4 , each set of pulleys 3 includes a first changing wheel 301 and a second changing wheel 302, the first changing wheel 301 is arranged horizontally, the second changing wheel 302 is arranged vertically, and the second changing wheel 302 is arranged on the four corners of the frame 10. This setting can ensure the stability of the upper air chamber 110 during the lifting process, prevent it from tilting due to uneven force, and even the risk of falling. The wire rope 2 can transmit loads over long distances, and has a safety factor of load-bearing. It has high tensile strength, fatigue resistance and impact resistance. It is safer and more reliable to use and is suitable for use in harsh working environments. The wire rope 2 is wound around the pulley group 3. Specifically, one end of the wire rope 2 is connected to the driving end of the drive module 1, and the other end passes through the first pulley and the second pulley respectively, and is finally connected to the upper air chamber 110. The drive module 1 can be a combination of a cylinder, a motor and a screw guide rail, etc. Exemplarily, the driving module 1 is a cylinder, an output end of the cylinder is connected to a turnbuckle, and one end of the wire rope 2 is connected to the output end of the cylinder through the turnbuckle.

[0039] During use, the cylinder's output end contracts. At this point, the steel wire rope 2, under the action of the first and second deflection wheels 301 and 302, converts horizontal motion into vertical motion, thereby driving the wind chamber upward. This allows workers to directly clean the bellows without removing the nozzle, simplifying the bellows cleaning process and improving efficiency, thereby increasing the speed of pole piece production to meet production needs.

[0040] The present invention is capable of raising and lowering the upper air chamber 110 in the oven 100 by setting a frame 10, a pulley block 3, a driving member and a steel wire rope 2, so as to facilitate subsequent staff to clean the air chamber. Among them, one end of the steel wire rope 2 is connected to the driving module 1, and the other end passes through the first changing wheel 301 and the second changing wheel 302 to connect to the upper air chamber 110, which can convert horizontal movement into vertical movement, and then lift the upper air chamber 110, leaving cleaning space for subsequent cleaning. The second changing wheel 302 is set at the four corners of the frame 10. Through this setting, the four ends of the upper air chamber 110 can be connected, making the rising process of the upper air chamber 110 more stable, and the upper air chamber 110 can be driven to move by a driving module 1. The pulley block 3 can reduce friction and reduce energy consumption. The present invention is simple to operate, stable and reliable in operation, can improve the efficiency of cleaning the oven 100, greatly improves the cleaning and maintenance space of the oven 100 and the convenience of cleaning, and meets production needs.

[0041] Example 2

[0042] Example 2 is similar to Example 1, except that this example further optimizes the air chamber lifting device 200. Figure 3 A pulley fixing seat 4 is provided on the frame 10, the driving module 1 is provided in the middle of the frame 10, the pulley fixing seat 4 is provided on one side of the driving end of the driving module 1, and at least four first changing wheels 301 are movably provided on the pulley fixing seat 4.

[0043] Specifically, a rotating shaft is provided on the pulley fixing seat 4, and the first changing wheel 301 is movably provided on the rotating shaft and can rotate relative to it. The driving module 1 is provided at the center of the frame 10, and the pulley fixing seat 4 is provided on the side facing the output end of the driving module 1. By providing the pulley fixing seat 4, the setting position of the first changing wheel 301 can be integrated to ensure that one driving module 1 can simultaneously drive four directions to move at a uniform speed, thereby further improving the stability of the lifting process. Preferably, there are six first changing wheels 301, and four first changing wheels 301 are integrated on the pulley fixing seat 4, and two first changing wheels 301 are respectively provided on both sides facing away from the pulley fixing seat 4, thereby improving the transmission efficiency of the wire rope 2 and ensuring the stability of the lifting process.

[0044] Please refer to Figure 4 In some embodiments, a mounting base 5 is connected to one end of the steel wire rope 2 near the upper air chamber 110, and the mounting base 5 is fixedly connected to the upper air chamber 110. When in use, the mounting base 5 is used to connect to the upper air chamber 110. The mounting base 5 can be fixedly connected to the upper air chamber 110 by bolts, and the steel wire rope 2 is driven to move by the air chamber lifting device 200, thereby driving the upper air chamber 110 to be lifted.

[0045] In some embodiments, a guide rod 6 is further included. One end of the guide rod 6 movably passes through the frame 10, and the other end is fixedly connected to the mounting base 5. The guide rod 6 can guide the upper air chamber 110 during lifting, preventing it from swinging during the ascent. The guide rod 6 is disposed on one side of the wire rope 2. One end of the guide rod 6 passes through a through hole in the frame 10 and is fixedly connected to the mounting base 5 via a threaded connection. The other end is disposed on the frame 10. When the wire rope 2 drives the upper air chamber 110 upward, the guide rod 6 moves upward with the upper air chamber 110, guiding it.

[0046] In some embodiments, please refer to Figure 6 The mounting base 5 is provided with a connecting rod 510, through which the steel wire rope 2 is connected to the mounting base 5. The connecting rod 510 is provided on the mounting base 5, through which the steel wire rope 2 is connected to the mounting base 5. Furthermore, a buckle 7 is included, through which the steel wire rope 2 is connected to the connecting rod 510. The buckle 7 is used for fastening, and the operation is convenient and quick, and the steel wire rope 2 can be easily removed from the mounting base 5.

[0047] In some embodiments, please refer to Figure 5A first stopper 610 is provided on the end of the guide rod 6 near the frame 10 to prevent the guide rod 6 from falling off the frame 10. The first stopper 610 can be a fixing block 620, a fixing nut, etc., and its diameter is larger than the diameter of the through hole in the frame 10. The first stopper 610 can limit the guide rod 6 to prevent the other end from falling off the frame 10. At the same time, when the wire rope 2 breaks, the first stopper 610 can also limit the upper air chamber 110, thereby improving the safety of the equipment.

[0048] Example 3

[0049] Example 3 is similar to Example 1, except that the wind chamber lifting device 200 is further optimized in this example.

[0050] Please refer to Figure 4 The frame 10 is also provided with an anti-falling component 8, which is arranged on a side close to the guide rod 6; the anti-falling component 8 includes a limit driving component 810 and a second limit member 820, and the limit driving component 810 is transmission-connected to the second limit member 820 to fix one end of the guide rod 6.

[0051] The anti-drop assembly 8 secures the guide rod 6, and thus the upper air chamber 110. When the upper air chamber 110 rises to a certain height, the guide rod 6 also rises a certain distance relative to the end surface of the frame 10. At this time, the anti-drop assembly 8 limits the position of the guide rod 6, improving the safety of equipment use. The limit drive 810 can be a cylinder, a motor, etc., and the limit member can be a limit block. The limit drive 810 pushes the limit block to move, thereby engaging the guide rod 6, preventing it from moving, and limiting the end of the guide rod 6 in the longitudinal position.

[0052] In some embodiments, please refer to Figure 5 The second limiting member 820 is a snap-fit ​​block with a snap-fit ​​groove 821. A fixing block 620 is provided on the end of the guide rod 6 near the anti-drop assembly 8, which fits into the snap-fit ​​groove 821. The second limiting member 820 is provided on one side of the guide rod 6, with the guide groove directly opposite the fixing block 620 on the guide rod 6. The fixing block 620 can be a nut that fits into the snap-fit ​​groove 821. By pushing the snap-fit ​​block, the snap-fit ​​groove 821 engages with the nut, thereby limiting the longitudinal position of the guide rod 6.

[0053] In some embodiments, the frame 10 is further provided with a positioning sensor for detecting the elevation distance of the guide rod 6. Specifically, the sensor can be a contact sensor, which is disposed on the frame 10 near the side of the guide rod 6. A sensing block can be provided at the end of the guide rod 6. When the guide rod 6 rises, the sensing block rises with it, and the contact sensor can sense the position of the sensing block. When it rises to a certain position, the contact sensor generates a signal feedback, which then controls the limit drive 810 to push the second limit member 820 to move, thereby limiting the position of the guide rod 6 and preventing it from being misaligned.
