[0046] Reference Figures 1 to 4According to a first aspect embodiment of the present invention, the guide roller replacement device 3 includes a frame, a conveying assembly 20, a lifting assembly 30, and a connecting assembly 40. The frame has a drying chamber 11 with a first horizontal direction (front-back direction in the figure) and a second horizontal direction (left-right direction in the figure), the first horizontal direction and the second horizontal direction being perpendicular to each other. Multiple guide rollers 1 are arranged in the chamber of the drying chamber 11, along the first horizontal direction. A replacement window 12 is provided on the chamber of the drying chamber 11. The conveying assembly 20 is mounted on the frame and located in the chamber of the drying chamber 11. The conveying assembly 20 includes a rotating mechanism 21 and a first driving mechanism 22. The rotating mechanism 21 rotates along the first horizontal direction. The guide rollers 1 are detachably mounted on the rotating mechanism 21. The output end of the first driving mechanism 22 is connected to the rotating mechanism 21. A drive mechanism 22 drives a rotary mechanism 21 to rotate so that multiple guide rollers 1 rotate in a first horizontal direction; a lifting assembly 30 is movably mounted on the frame and located below the rotary mechanism 21, the position of the lifting assembly 30 corresponds to the position of the replacement window 12, the lifting assembly 30 includes a movable lifting platform 31, the lifting platform 31 is used to place the guide rollers 1, the lifting platform 31 is driven to rise or fall so that the guide rollers 1 move away from or closer to the rotary mechanism 21, the guide rollers 1 can be mounted on the rotary mechanism 21; a connecting assembly 40 is slidably mounted inside the drying chamber 11, the end of the guide rollers 1 can abut against the connecting assembly 40, the guide rollers 1 are electrically connected to the connecting assembly 40.

[0047] Specifically, this utility model relates to a quick-change device for guide roller 1 of a coating dryer, aiming to provide an efficient and convenient replacement solution for guide roller 1 to meet the needs of frequent guide roller 1 replacement in film coating production lines. The following are specific embodiments of this utility model:

[0048] The quick-change device for guide rollers 1 in a coating dryer according to this invention first includes a frame on which a drying chamber 11 is fixedly mounted. The drying chamber 11 is designed to meet the requirements of the film coating process, having a clearly defined first horizontal direction and a second horizontal direction, which are perpendicular to each other. Multiple guide rollers 1 are arranged along the first horizontal direction inside the drying chamber 11. These guide rollers 1 are key components for the transmission and guidance of the film during the drying process. To facilitate the replacement of the guide rollers 1, a replacement window 12 is specially provided on the drying chamber 11. To achieve quick replacement of the guide rollers 1, this invention includes a conveying assembly 20 on the frame. The conveying assembly 20 is located inside the drying chamber 11 and includes a rotary mechanism 21 and a first drive mechanism 22. The rotary mechanism 21 is designed to rotate along the first horizontal direction, and the guide rollers 1 are detachably mounted on the rotary mechanism 21. The output end of the first drive mechanism 22 is connected to the rotary mechanism 21. When the first drive mechanism 22 is started, it drives the rotary mechanism 21 to rotate, thereby causing multiple guide rollers 1 to rotate in the first horizontal direction and stop at the replacement window 12 for replacement. Therefore, the rotary mechanism 21 provides convenience for the replacement of guide rollers 1. This utility model also provides a lifting assembly 30, which is movably mounted on the frame and located below the rotary mechanism 21. The position of the lifting assembly 30 corresponds to the position of the replacement window 12. This design allows for convenient operation of the lifting assembly 30 through the replacement window 12 when replacing guide rollers 1. The lifting assembly 30 includes a movable lifting platform 31 for placing the guide roller 1 to be replaced. By driving the lifting platform 31 to rise or fall, the guide roller 1 can be moved away from or closer to the rotary mechanism 21, thereby realizing the installation and removal of the guide roller 1. Finally, this utility model also provides a connecting assembly 40, which is slidably disposed inside the drying chamber 11. The end of guide roller 1 can abut against the connecting component 40, and an electrical connection is established between guide roller 1 and connecting component 40. This design not only ensures the stability and accuracy of guide roller 1 during replacement, but also guarantees that guide roller 1 can normally receive power drive or signal transmission during operation. After all guide rollers 1 have been replaced, the conveying component 20 and the lifting component 30 can stop working, and guide roller 1 will remain in a specific position and be electrically connected to the connecting component 40, thereby driving guide roller 1 to rotate. The quick replacement device for guide roller 1 of the coating dryer of this utility model, through the ingenious design of the frame, conveying component 20, lifting component 30 and connecting component 40, realizes the quick and convenient replacement of guide roller 1, which greatly improves the efficiency and flexibility of the film coating production line.

[0049] In practical applications, when guide roller 1 needs to be replaced, the first drive mechanism 22 drives the rotary mechanism 21 to rotate the guide roller 1 to be replaced to the replacement window 12 position. Then, the lifting platform 31 of the lifting assembly 30 lifts the guide roller 1 from the rotary mechanism 21 and lowers it slightly to disconnect the guide roller 1 from the rotary mechanism 21 and the connecting assembly 40. Afterward, the old guide roller 1 can be removed from the replacement window 12, and the new guide roller 1 can be inserted through the window. The lifting assembly 30 then lifts the new guide roller 1 to the appropriate position and reconnects it to the rotary mechanism 21 and the connecting assembly 40. Finally, the first drive mechanism 22 rotates the new guide roller 1 back to the working position, completing the replacement process.

[0050] Therefore, it can be understood that the guide roller replacement device 3 according to the present utility model embodiment has at least the following beneficial effects: the guide roller 1 is conveyed to the replacement window 12 on the drying box 11 by the rotary mechanism 21. After the technician opens the replacement window 12 and removes the guide roller 1, the new guide roller 1 can be installed on the rotary mechanism 21 by the lifting component 30. Under the rotation action of the rotary mechanism 21, the guide roller 1 can be replaced one by one, so that the newly replaced guide roller 1 is clean and free of coating. It can also meet different film coating production requirements by replacing guide rollers of different models.

[0051] Furthermore, referring to Figures 3 to 5 In some embodiments of this utility model, the rotary mechanism 21 includes a support frame 211, a transmission component 212, and a conveyor belt 213. The support frame 211 is disposed in the body of the drying chamber 11; the transmission component 212 is wound around the first drive mechanism 22, and the support frame 211 is disposed between the transmission components 212. The support frame 211 is used to support the transmission component 212, and the first drive mechanism 22 drives the transmission component 212 to rotate; the conveyor belt 213 is disposed on the transmission component 212, and multiple sets of mounting seats 214 are disposed on the conveyor belt 213. The multiple sets of mounting seats 214 are arranged along a first horizontal direction, and the mounting seats 214 are used to mount the guide roller 1.

[0052] This embodiment further details the specific structure and function of the rotary mechanism 21: The rotary mechanism 21 first includes a support frame 211, which is firmly installed inside the drying chamber 11. The support frame 211 is designed to provide a stable platform for supporting the transmission component 212 and ensuring its stability and reliability during rotation. The transmission component 212 is one of the core components of the rotary mechanism 21, and it is wound around the first drive mechanism 22. The support frame 211 is positioned between the transmission components 212, which not only enhances the supporting force of the transmission component 212 but also ensures that the transmission component 212 remains stable during rotation. When the first drive mechanism 22 is activated, it drives the transmission component 212 to rotate, thereby driving the conveyor belt 213 to rotate, which in turn drives the guide roller 1 to rotate, ultimately achieving rapid replacement of the guide roller 1. The conveyor belt 213 is a key component in the rotary mechanism 21 used to carry and transport the guide roller 1. It is mounted on the transmission component 212 and moves with the rotation of the transmission component 212. To facilitate the installation and fixation of the guide roller 1, multiple sets of mounting seats 214 are provided on the conveyor belt 213. These mounting seats 214 are arranged along a first horizontal direction to ensure the orderly arrangement and stable transmission of the guide roller 1 on the conveyor belt 213. The design of the mounting seats 214 allows the guide roller 1 to be securely installed on them and to be easily removed when replacement is required.

[0053] When replacing guide roller 1, the first drive mechanism 22 first drives the transmission component 212 to rotate, which in turn drives the conveyor belt 213 and the guide roller 1 on the mounting base 214 to rotate together. When the guide roller 1 to be replaced rotates to the replacement window 12 position, the first drive mechanism 22 stops. Next, the lifting platform 31 of the lifting assembly 30 lifts the guide roller 1 to be replaced from the mounting base 214 and lowers it slightly to disconnect the guide roller 1 from the mounting base 214. Then, the old guide roller 1 can be removed from the replacement window 12, and the new guide roller 1 can be inserted through the window. The lifting assembly 30 then lifts the new guide roller 1 to the appropriate position and reconnects it to the mounting base 214. Finally, the first drive mechanism 22 is started, driving the transmission component 212 and the conveyor belt 213 to rotate, rotating the new guide roller 1 back to the working position. At the same time, the end of the new guide roller 1 abuts against the connecting assembly 40, achieving electrical connection and ensuring the normal operation of the dryer.

[0054] Furthermore, referring to Figures 3 to 5In some embodiments of this utility model, the support frame 211 includes a first support rod 2111 and a second support rod 2112. The first support rod 2111 extends along a second horizontal direction and is disposed in the body of the drying chamber 11. The first support rod 2111 is located between the transmission members 212. The second support rod 2112 extends along a first horizontal direction and is disposed on the first support rod 2111. A rolling member 2113 is disposed on one side end of the second support rod 2112. The rolling members 2113 are arranged along the first horizontal direction. The rolling members 2113 can abut against the transmission member 212 or the conveyor belt 213. The rolling members 2113 can rotate in the second support rod 2112.

[0055] Specifically, the support frame 211 is implemented as follows: The support frame 211 is an important component of the rotary mechanism 21, and it mainly includes a first support rod 2111 and a second support rod 2112. The first support rod 2111 extends along a second horizontal direction and is disposed in the body of the drying chamber 11, and is located between the transmission components 212. Its main function is to provide a stable support foundation to ensure that the transmission components 212 can rotate smoothly on it. The second support rod 2112 extends along a first horizontal direction and is disposed on the first support rod 2111. At one end of the second support rod 2112, a plurality of rolling elements 2113 are disposed. These rolling elements 2113 are arranged along the first horizontal direction and can abut against the transmission components 212 or the conveyor belt 213. That is, the rolling elements located on the upper side can abut against the lower side of the transmission component 212, and the rolling elements located on the lower side can be located on the lower side of the conveyor belt 213 to support the conveyor belt 213. The design of the rolling element 2113 reduces friction and improves rotational efficiency during the rotation of the transmission element 212 or the conveyor belt 213. Simultaneously, the rolling element 2113 can also rotate within the second support rod 2112, further ensuring the smooth movement of the transmission element 212 and the conveyor belt 213. The rolling element 2113 can be a roller or a roller with a connecting I-groove for connecting to the transmission element 212. The transmission element 212 can be a chain or a transmission belt.

[0056] The support frame 211 plays a crucial role in the replacement of guide roller 1. When the first drive mechanism 22 drives the transmission component 212 to rotate, the transmission component 212 drives the rolling component 2113 to rotate on the second support rod 2112. This design not only reduces friction but also improves the stability and efficiency of rotation. At the same time, because the support frame 211 provides a stable support base, the transmission component 212 and the conveyor belt 213 can remain stable during rotation, thereby ensuring the stability and safety of guide roller 1.

[0057] Specifically, refer to Figures 3 to 5In some embodiments of this utility model, the conveyor belt 213 includes multiple support plates 2131, which are arranged sequentially on the outer side of the transmission member 212, and mounting seats 214 are disposed on the support plates 2131. The conveyor belt 213 is a key component of the rotary mechanism 21, mainly responsible for supporting and conveying the guide roller 1. According to the design of this utility model, the conveyor belt 213 includes multiple support plates 2131, which are arranged sequentially on the outer side of the transmission member 212. The design of the support plates 2131 enables the conveyor belt 213 to support the guide roller 1 more stably and to rotate smoothly under the drive of the transmission member 212. Mounting seats 214 are provided on the support plates 2131. These mounting seats 214 are used to mount the guide roller 1, which can firmly fix the guide roller 1 and ensure the stability and safety of the guide roller 1 during rotation. The design of the mounting seats 214 makes the replacement of the guide roller 1 more convenient, requiring only simple disassembly and installation.

[0058] The conveyor belt 213 plays a crucial role in the replacement of guide roller 1. When the first drive mechanism 22 drives the transmission component 212 to rotate, the transmission component 212 drives the guide roller 1 on the support plate 2131 and the mounting base 214 to rotate together. This design allows the guide roller 1 to easily rotate to the replacement window 12 position for easy replacement. Simultaneously, because the support plate 2131 provides a stable support base, the guide roller 1 remains stable during rotation, thus ensuring the stability and continuity of the film coating process. Furthermore, the design of the conveyor belt 213 makes the replacement of guide roller 1 faster and more efficient. The old guide roller 1 can simply be removed through the replacement window 12, and then the new guide roller 1 can be installed on the mounting base 214. This design significantly reduces the time and labor costs required to replace the guide roller 1.

[0059] Reference Figures 3 to 6 Furthermore, in some embodiments of this utility model, each set of mounting bases 214 includes a fixed base 2141 and a locking base 2142. The fixed base 2141 and the locking base 2142 are arranged at both ends of the conveyor belt 213 along the second horizontal direction. Along the second horizontal direction, the fixed base 2141 is located at the end away from the replacement window 12, and the locking base 2142 is located at the end close to the replacement window 12. The fixed base 2141 is used to support one end of the guide roller 1, and the locking base 2142 is used to install and lock the other end of the guide roller 1.

[0060] Specifically, the mounting base 214 is implemented as follows: The mounting base 214 is a key component on the conveyor belt 213 for mounting and fixing the guide roller 1. According to the design of this utility model, each set of mounting bases 214 includes a fixing base 2141 and a locking base 2142, which are arranged at both ends of the conveyor belt 213 along the second horizontal direction. The fixing base 2141 is located at the end away from the replacement window 12, and its main function is to support one end of the guide roller 1, ensuring that the guide roller 1 remains stable during rotation. The design of the fixing base 2141 allows one end of the guide roller 1 to be firmly fixed thereon, preventing the guide roller 1 from shaking or falling off during rotation or operation. The locking base 2142 is located at the end closer to the replacement window 12, and its function is to install and lock the other end of the guide roller 1. The design of the locking base 2142 allows the other end of the guide roller 1 to be easily installed and removed, while ensuring that the guide roller 1 can be firmly locked on the locking base 2142 during rotation and operation, maintaining stability.

[0061] The mounting base 214 plays a crucial role in the replacement of guide roller 1. First, the transmission component 212 is rotated by the first drive mechanism 22 to rotate the guide roller 1 to be replaced to the position of the replacement window 12. Then, the lifting platform 31 of the lifting assembly 30 slightly lifts one end of the guide roller 1 from the locking seat 2142, and the locking seat 2142 is released from its locked state. Next, the old guide roller 1 can be moved out of the replacement window 12, and the new guide roller 1 is inserted through the window. The other end of the new guide roller 1 is placed on the fixed seat 2141 by the lifting assembly 30, and then one end of the new guide roller 1 is mounted on the locking seat 2142 and locked. Finally, the replacement of guide roller 1 is completed. This design makes the replacement of guide roller 1 faster and more efficient. Since the fixed seat 2141 and the locking seat 2142 are located at both ends of the conveyor belt 213 and are arranged along the second horizontal direction, the replacement operation of guide roller 1 can be conveniently performed through the replacement window 12. Meanwhile, the design of the fixed seat 2141 and the locking seat 2142 also ensures the stability and safety of the guide roller 1 during rotation and operation.

[0062] Furthermore, referring to Figure 6In some embodiments of this utility model, the locking seat 2142 includes a shaft seat 2142a and a shaft cover 2142b. The shaft seat 2142a is disposed on the conveyor belt 213, and the shaft cover 2142b is rotatably disposed on the shaft seat 2142a. A mounting hole 2142c is provided between the shaft seat 2142a and the shaft cover 2142b for mounting one end of the guide roller 1. The specific implementation of the locking seat 2142 is as follows: The locking seat 2142 is a key component of the mounting seat 214, primarily responsible for mounting and locking one end of the guide roller 1. According to the design of this utility model, the locking seat 2142 includes a shaft seat 2142a and a shaft cover 2142b. The shaft seat 2142a is disposed on the conveyor belt 213, providing a stable support base for mounting one end of the guide roller 1. The design of the shaft seat 2142a ensures that the guide roller 1 remains smooth and stable after installation. The shaft cover 2142b is rotatably mounted on the shaft seat 2142a. This design allows the shaft cover 2142b to be opened when needed for the installation or removal of the guide roller 1. Simultaneously, the shaft cover 2142b can be securely locked onto the shaft seat 2142a after the guide roller 1 is installed, preventing the guide roller 1 from loosening or falling off during rotation or operation. A mounting hole 2142c is provided between the shaft seat 2142a and the shaft cover 2142b. This mounting hole 2142c is used to mount one end of the guide roller 1. The design of the mounting hole 2142c ensures that the guide roller 1 can be accurately mounted on the locking seat 2142 and maintain a stable connection.

[0063] The locking seat 2142 plays a crucial role in the replacement of guide roller 1. First, the transmission component 212 is rotated by the first drive mechanism 22 to rotate the guide roller 1 to be replaced to the position of the replacement window 12. Then, the shaft cover 2142b is opened using a tool or manually, and one end of the guide roller 1 is removed from the mounting hole 2142c. Next, the old guide roller 1 can be moved out of the replacement window 12, and the new guide roller 1 is inserted through the window, aligning one end of the new guide roller 1 with the mounting hole 2142c and installing it. Finally, the shaft cover 2142b is closed and locked onto the shaft seat 2142a, completing the replacement of guide roller 1. This design makes the replacement of guide roller 1 faster and more convenient. Since the shaft cover 2142b is rotatably mounted on the shaft seat 2142a, it can be easily opened and closed, thus simplifying the replacement process of guide roller 1. Meanwhile, the design of the mounting hole 2142c also ensures that the guide roller 1 can be accurately installed on the locking seat 2142 and maintain a stable connection, thereby improving the production efficiency and product quality of the film coating production line.

The driving member 221 is mounted on the support frame 211; the driving wheel set 222 is rotatably mounted in the body of the drying chamber 11, the output end of the driving member 221 is connected to the driving wheel set 222, and the driving member 221 drives the driving wheel set 222 to rotate, and the transmission member 212 is wound around the driving wheel set 222; along the second horizontal direction, the driven wheel set 223 is rotatably mounted at the other end of the body of the drying chamber 11, and the transmission member 212 is wound around the driven wheel set 223, and the transmission member 212 drives the driven wheel set 223 to rotate.

[0065] In some embodiments, the first driving mechanism 22 is specifically implemented as follows: The first driving mechanism 22 is the power source for the rotary mechanism 21, and it is mainly responsible for driving the transmission member 212 to rotate. According to the design of this utility model, the first driving mechanism 22 includes a driving member 221, a driving wheel set 222, and a driven wheel set 223. The driving member 221 is mounted on the support frame 211, and it provides the power required for the rotary motion. The design of the driving member 221 ensures that it can stably output power and drive the driving wheel set 222 to rotate. The driving wheel set 222 is rotatably mounted in the body of the drying chamber 11. The output end of the driving member 221 is connected to the driving wheel set 222, and when the driving member 221 is started, it drives the driving wheel set 222 to rotate. The transmission member 212 is wound around the driving wheel set 222, so that when the driving wheel set 222 rotates, it drives the transmission member 212 to rotate together. The driven wheel set 223 is rotatably mounted at the other end of the body of the drying chamber 11 along the second horizontal direction. The transmission component 212 is also wound around the driven wheel assembly 223. When the transmission component 212 rotates under the drive of the driving wheel assembly 222, it simultaneously drives the driven wheel assembly 223 to rotate. This design ensures the stability and balance of the transmission component 212 during rotation.

[0066] The first drive mechanism 22 plays a crucial role in the replacement of guide roller 1. First, the drive unit 221 is activated, outputting power to drive the drive wheel assembly 222 to rotate. Then, the drive wheel assembly 222 drives the transmission unit 212 to rotate together. Since the transmission unit 212 is wound around both the drive wheel assembly 222 and the driven wheel assembly 223, its rotation also drives the driven wheel assembly 223 to rotate. This design ensures the smooth and stable rotation of the transmission unit 212, thus guaranteeing the stability and safety of guide roller 1 during replacement. Simultaneously, because the first drive mechanism 22 provides sufficient power to drive the transmission unit 212, it also improves the efficiency and convenience of guide roller 1 replacement. The first drive mechanism 22 of the quick-change device for the guide roller 1 of the coating dryer, through the ingenious design of the drive component 221, the active wheel group 222 and the driven wheel group 223, realizes the smooth rotation of the transmission component 212, further improving the maintenance efficiency and production continuity of the film coating production line.

[0067] Reference Figures 3 to 5 In some embodiments of this utility model, the lifting assembly 30 further includes a slide 32 and a lifting mechanism 33. The slide 32 is slidably mounted on the body of the drying chamber 11 and slides along a second horizontal direction. The lifting mechanism 33 is mounted on the slide 32, and the lifting platform 31 is mounted on the slide 32 via the lifting mechanism 33. The lifting mechanism 33 includes a guide rod 331 and a drive assembly 332. The guide rod 331 is vertically mounted on the slide 32, and the lifting platform 31 is sleeved on the guide rod 331. The drive assembly 332 is located between the slide 32 and the lifting platform 31 and is used to drive the lifting platform 31 to move vertically.

[0068] In some embodiments, the lifting assembly 30 is specifically implemented as follows: The lifting assembly 30 is an important part of the quick-change device for the guide roller 1 of the coating dryer. It is mainly responsible for slightly lifting the guide roller 1 from the conveyor belt 213 for replacement. According to the design of this utility model, the lifting assembly 30 includes a lifting platform 31, a slide 32, and a lifting mechanism 33. The slide 32 is slidably mounted on the body of the drying chamber 11 and slides along a second horizontal direction. This design allows the slide 32 to move to a designated position when needed to lift the guide roller 1. The lifting mechanism 33 is mounted on the slide 32, and the lifting platform 31 is mounted on the slide 32 via the lifting mechanism 33. The main function of the lifting mechanism 33 is to drive the lifting platform 31 to move vertically upwards and downwards to slightly lift the guide roller 1 from the conveyor belt 213. The lifting mechanism 33 specifically includes a guide rod 331 and a drive assembly 332. The guide rod 331 is vertically mounted on the slide 32, providing guidance for the lifting platform 31's vertical movement. The lifting platform 31 is fitted onto the guide rod 331, allowing for stable vertical movement along the guide rod 331 when the drive assembly 332 is operating. The drive assembly 332 is positioned between the slide 32 and the lifting platform 31, providing the power required for the lifting platform 31's vertical movement. When it is necessary to lift the guide roller 1, the drive assembly 332 operates, driving the lifting platform 31 to rise vertically, slightly lifting the guide roller 1 off the conveyor belt 213. After the replacement operation is completed, the drive assembly 332 then drives the lifting platform 31 to descend, returning it to its original position.

[0069] This design makes the replacement of guide roller 1 faster and more convenient. Since the lifting assembly 30 can easily lift the guide roller 1 slightly off the conveyor belt 213, the replacement process is greatly simplified. At the same time, since the lifting and lowering movement of the lifting platform 31 is achieved through the lifting mechanism 33, the stability and safety of the lifting process are also ensured. It should be noted that the aforementioned drive assembly 332 can be a hydraulic cylinder lifting drive, a pneumatic cylinder lifting drive, or a gear and rack horizontal push drive; no specific limitation is made in this embodiment.

[0070] Reference Figures 3 to 4 as well as Figures 6 to 7In some embodiments of this utility model, the connecting assembly 40 includes: a guide slide 41 and an electrical connector 42. The guide slide 41 is movably disposed on the inner wall of the drying chamber 11. A limiting groove 411 is provided on one side of the guide slide 41. The limiting groove 411 extends along a first horizontal direction. One end of the guide roller 1 can slide in the limiting groove 411. An installation slot 412 is provided in the limiting groove 411. The installation slots 412 are arranged at intervals along the first horizontal direction. The positions of the installation slots 412 correspond one-to-one with the positions of the guide roller 1. Multiple electrical connectors 42 are provided. The electrical connectors 42 are slidably disposed in the installation slots 412 by means of an elastic element 423. A pin 421 is provided in the installation slot 412. The pin 421 can pass through the electrical connector 42. One end of the pin 421 is electrically connected to the outside, and the other end of the pin 421 is used to abut against the end of the guide roller 1. The pin 421 is electrically connected to the guide roller 1.

[0071] Specifically, in some embodiments, the connecting component 40 is implemented as follows: The connecting component 40 is an important part of the quick-change device for the guide roller 1 of the coating dryer, and it is mainly responsible for realizing the electrical connection between the guide roller 1 and the drying chamber 11. According to the design of this utility model, the connecting component 40 includes a guide slide 41 and an electrical connection seat 42.

[0072] The guide slide 41 is movably mounted on the inner wall of the drying chamber 11. A limiting groove 411 is provided on one side of the guide slide 411, extending along a first horizontal direction. Thus, when the guide roller 1 needs to be replaced, one end of the guide roller 1 can be placed into the limiting groove 411 and slid along the first horizontal direction. Mounting slots 412 are provided in the limiting groove 411. These mounting slots 412 are arranged at intervals along the first horizontal direction, and their positions correspond one-to-one with the positions of the guide rollers 1. Thus, each guide roller 1 has a corresponding mounting slot 412 for mounting the electrical connector 42. Multiple electrical connectors 42 are provided, slidably mounted in the mounting slots 412 by elastic members 423. Thus, when the end of the guide roller 1 is placed into the limiting groove 411 and slides to the corresponding mounting slot 412 position, the electrical connector 42 can make tight contact with the end of the guide roller 1 under the action of the elastic member 423. A ejector pin 421 is also provided in the mounting slot 412. The ejector pin 421 can pass through the electrical connector 42, and one end of it is electrically connected to the outside, while the other end is used to abut against the end of the guide roller 1. In this way, when the electrical connector 42 is in close contact with the end of the guide roller 1, the ejector pin 421 can transfer external electrical energy to the guide roller 1, realizing the electrical connection between the guide roller 1 and the drying chamber 11. It should be noted that the two sides of the electrical connector 42 in the first horizontal direction should be provided with transition rounded corners to facilitate the guide roller 1 to slide to the top of the electrical connector 42 and press the electrical connector 42 to the right.

[0073] The connecting assembly 40 plays a crucial role in the replacement of guide roller 1. First, one end of the replaced guide roller 1 is driven by the conveying assembly 20 and slides from one end of the guide slide block 41 into the limiting slide groove 411, allowing it to slide along the first horizontal direction. Then, when the end of the guide roller 1 slides to the corresponding mounting slot 412, the guide roller 1 presses against the electrical connector 42, causing the electrical connector 42 to slide within the mounting slot 412. Simultaneously, the electrical connector 42, under the action of the elastic element 423, makes tight contact with the end of the guide roller 1. Next, the guide slide 41 is driven close to the guide roller 1 by a drive device (not shown in the figure). At this time, the bottom of the mounting slot 412 of the guide slide 41 further presses the elastic element 423, and the ejector pin 421 slides in the electrical connector 42, so that one end of the ejector pin 421 abuts against the contact point at the end of the guide roller 1. Therefore, the ejector pin 421 can transfer external electrical energy to the guide roller 1, realizing the electrical connection between the guide roller 1 and the drying chamber 11, and providing a power source for the rotation of the guide roller 1. This design makes the replacement of the guide roller 1 and the electrical connection faster and more convenient. Through the conveying assembly 20, it can be ensured that the guide roller 1 can accurately slide to the corresponding position during the replacement process and realize a stable electrical connection. At the same time, since the electrical connector 42 is slidably set in the mounting slot 412 by the elastic element 423, it can also ensure a tight contact and a stable electrical connection between the guide roller 1 and the electrical connector 42.

[0074] Furthermore, referring to Figures 6 to 7 In some embodiments of this invention, a sealing ring 422 is provided at the end of the electrical connector 42 and / or the end of the guide roller 1. In the quick-change device for the guide roller 1 of the coating dryer, the stability of the electrical connection between the electrical connector 42 and the guide roller 1, as well as its dustproof and waterproof performance, are crucial. Therefore, according to the design of this invention, a sealing ring 422 is provided at the end of the electrical connector 42 and / or the end of the guide roller 1.

[0075] The sealing ring 422 is typically made of an elastic material, such as rubber or silicone. When the electrical connector 42 is in close contact with the end of the guide roller 1, the sealing ring 422 effectively fills the tiny gap between them, preventing dust, moisture, or other impurities from entering the electrical connection and ensuring the stability and reliability of the electrical connection. One or more sealing rings 422 can be provided at the end of the electrical connector 42. These sealing rings 422 can fit tightly against the end face of the electrical connector 42, ensuring a good seal when in contact with the end of the guide roller 1. Similarly, one or more sealing rings 422 can also be provided at the end of the guide roller 1. These sealing rings 422 can fit tightly against the end face of the guide roller 1, forming a seal when in contact with the end of the electrical connector 42.

[0076] The material of the sealing ring 422 should possess good elasticity, wear resistance, and corrosion resistance to ensure its stability and durability during long-term use. Commonly used materials for sealing ring 422 include rubber, silicone, and polyurethane. The main function of the sealing ring 422 is to prevent dust, moisture, or other impurities from entering the electrical connection parts, ensuring the stability and reliability of the electrical connection. Simultaneously, the sealing ring 422 also provides a certain degree of cushioning, reducing the impact and vibration between the electrical connector 42 and the end of the guide roller 1, thereby extending its service life.

[0077] Reference Figures 1 to 2 The present invention also provides a coating dryer according to a second aspect embodiment, which includes a guide roller replacement device 3 according to any one of the first aspects embodiments. This coating dryer ingeniously integrates multiple functions such as coating, drying, and quick replacement of the guide roller 1. The quick replacement device for the guide roller 1 simplifies the replacement process of the guide roller 1, thereby reducing maintenance time and improving the overall operating efficiency of the production line. Therefore, it can be understood that the coating dryer according to the embodiments of the present invention has at least the following beneficial effects: the coating dryer conveys the guide roller 1 to the replacement window 12 on the drying chamber 11 via the rotary mechanism 21. After the technician opens the replacement window 12 and removes the guide roller 1, the new guide roller 1 can be installed on the rotary mechanism 21 via the lifting assembly 30. Under the rotation of the rotary mechanism 21, the guide rollers 1 can be replaced one by one, so that the newly replaced guide roller 1 is clean and free of adhering coating, and different models of guide roller 1 can be replaced to meet different film coating production requirements.

[0078] Reference Figures 1 to 2 In some embodiments of this invention, the coating dryer further includes a drying device 2, which is disposed within the drying chamber 11 and located above the guide roller changing device 3. The drying device 2 is used to dry the coated film. This invention further includes the drying device 2, which is housed inside the drying chamber 11 and located above the quick-change device for the guide rollers 1 of the coating dryer. Its main function is to dry the coated film.

[0079] The drying unit 2 can be composed of a series of efficient and energy-saving drying elements, such as heating elements and a hot air circulation system, which work together to ensure that the film is dried quickly and evenly after coating. The drying unit 2 utilizes advanced heating and hot air circulation technology to ensure that the film achieves the ideal drying effect in a short time. Through a precisely controlled drying process, the drying unit 2 ensures that all parts of the film achieve a uniform drying effect, thereby avoiding quality problems caused by uneven drying. While providing efficient drying performance, the drying unit 2 also focuses on energy conservation and environmental protection, employing multiple energy-saving technologies and measures to reduce energy consumption and emissions.

[0080] Therefore, it is understandable that the coating dryer, which combines the quick-change device for the guide roller 1 and the high-efficiency drying device 2, demonstrates significant advantages in terms of production efficiency, ease of operation, product quality, and energy utilization. This innovative design not only improves the overall performance of the film coating production line but also brings users greater economic and environmental benefits.
