The position of the lifting component 30 corresponds to the position of the replacement window 12. The lifting component 30 includes a movable lifting platform 31. The lifting platform 31 is used to place the guide roller 1. The lifting platform 31 is driven to rise and fall to make the guide roller 1 move away from or close to the rotating mechanism 21. The guide roller 1 can be installed on the rotating mechanism 21; the connecting component 40 can be slidably arranged on the inner side of the drying box 11, and the end of the guide roller 1 can abut against the connecting component 40. The guide roller 1 is electrically connected to the connecting component 40.

[0056] Specifically, the present invention relates to a coating dryer guide roller 1 quick replacement device, which aims to provide an efficient and convenient guide roller 1 replacement solution to meet the needs of frequent replacement of guide rollers 1 in film coating production lines. The following is a specific implementation of the present invention:

[0057] The coating dryer guide roller 1 quick replacement device described in the present invention first includes a frame, on which a drying box 11 is fixedly installed. The design of the drying box 11 takes into account the requirements of the film coating process, and has a clear first horizontal direction and a second horizontal direction, and the two directions are perpendicular to each other. A plurality of guide rollers 1 are arranged along the first horizontal direction inside the drying box 11, and these guide rollers 1 are key components for transmitting and guiding the film during the drying process. In order to facilitate the replacement of the guide roller 1, a replacement window 12 is also specially provided on the drying box 11. In order to achieve the quick replacement of the guide roller 1, the present invention is provided with a conveying assembly 20 on the frame. The conveying assembly 20 is located in the drying box 11, and includes a rotating mechanism 21 and a first driving mechanism 22. The rotating mechanism 21 is designed to be able to rotate along the first horizontal direction, and the guide roller 1 is detachably mounted on the rotating mechanism 21. The output end of the first driving mechanism 22 is connected to the rotating mechanism 21. When the first driving mechanism 22 is started, it drives the rotating mechanism 21 to rotate, so that the multiple guide rollers 1 rotate in the first horizontal direction and stay at the replacement window 12 for replacement. Therefore, the rotating mechanism 21 can provide convenience for the replacement of the guide rollers 1. The present invention also provides a lifting component 30, which can be movably mounted on the frame and is located below the rotating mechanism 21. The position of the lifting component 30 corresponds to the position of the replacement window 12. This design is to facilitate the operation of the lifting component 30 through the replacement window 12 when replacing the guide roller 1. The lifting component 30 includes a movable lifting platform 31, which is used to place the guide roller 1 to be replaced. By driving the lifting platform 31 to rise and fall, the guide roller 1 can be moved away from or close to the rotating mechanism 21, thereby realizing the installation and removal of the guide roller 1. Finally, the present invention also provides a connecting component 40, which can be slidably arranged inside the box body of the drying box 11. The end of the guide roller 1 can abut against the connecting component 40, and an electrical connection is achieved between the guide roller 1 and the connecting component 40. Such a design not only ensures the stability and accuracy of the guide roller 1 during the replacement process, but also ensures that the guide roller 1 can normally receive power drive or signal transmission when working. After all the guide rollers 1 are replaced, the transmission component 20 and the lifting component 30 can stop working, and the guide roller 1 stays at a specific position and is electrically connected to the connecting component 40, thereby driving the guide roller 1 to rotate. The coating dryer guide roller 1 quick replacement device of the present invention realizes the fast and convenient replacement of the guide roller 1 through the ingenious design of the frame, the transmission component 20, the lifting component 30 and the connecting component 40, thereby greatly improving the efficiency and flexibility of the thin film coating production line.

[0058] In actual application, when the guide roller 1 needs to be replaced, the first driving mechanism 22 is used to drive the slewing mechanism 21 to rotate the guide roller 1 to be replaced to the position of the replacement window 12. Subsequently, the lifting platform 31 of the lifting assembly 30 is used to lift the guide roller 1 from the slewing mechanism 21 and slightly lower it, so as to release the connection between the guide roller 1 and the slewing mechanism 21 and the connecting assembly 40. After that, the old guide roller 1 can be removed from the replacement window 12, and the new guide roller 1 can be put in through the window, and then the new guide roller 1 can be lifted to the appropriate position by the lifting assembly 30, and reconnected with the slewing mechanism 21 and the connecting assembly 40. Finally, the new guide roller 1 is rotated back to the working position by the first driving mechanism 22 to complete the replacement process.

[0059] Therefore, it can be understood that the guide roller replacement device 3 of the coating dryer according to the embodiment of the present invention has at least the following beneficial effects: the guide roller 1 is transferred to the replacement window 12 on the drying box 11 through the rotating mechanism 21, and the technician opens the replacement window 12. After the guide roller 1 is removed, the replaced new guide roller 1 can be installed on the rotating mechanism 21 through the lifting assembly 30. Under the rotation of the rotating mechanism 21, the guide rollers 1 can be replaced one by one, so that the newly replaced guide rollers 1 are clean and free of adhered paint, and different types of guide rollers 1 can be replaced to meet different film coating production requirements.

[0060] Further, refer to Figures 3 to 5 In some embodiments of the present invention, the rotary mechanism 21 includes a support frame 211, a transmission member 212, and a conveyor belt 213. The support frame 211 is arranged in the body of the drying box 11; the transmission member 212 is wound around the first driving mechanism 22, the support frame 211 is arranged between the transmission members 212, the support frame 211 is used to support the transmission member 212, and the first driving mechanism 22 drives the transmission member 212 to rotate; the conveyor belt 213 is arranged on the transmission member 212, and a plurality of mounting seats 214 are arranged on the conveyor belt 213, and the plurality of mounting seats 214 are arranged along the first horizontal direction, and the mounting seats 214 are used to install the guide roller 1.

[0061] This embodiment further describes in detail the specific structure and function of the slewing mechanism 21: the slewing mechanism 21 first includes a support frame 211, which is firmly arranged inside the body of the drying box 11. The design of the support frame 211 is to provide a stable platform for supporting the transmission member 212 and ensuring its stability and reliability during the rotation process. The transmission member 212 is one of the core components of the slewing mechanism 21, and it is wound around the first driving mechanism 22. The support frame 211 is arranged between the transmission members 212. This design not only enhances the supporting force of the transmission member 212, but also ensures that the transmission member 212 can remain stable during rotation. When the first driving mechanism 22 is started, it drives the transmission member 212 to rotate, thereby driving the conveyor belt 213 to rotate, and then driving the guide roller 1 to rotate, and finally realizing the rapid replacement of the guide roller 1. The conveyor belt 213 is a key component in the slewing mechanism 21 for carrying and transmitting the guide roller 1. It is arranged on the transmission member 212 and moves with the rotation of the transmission member 212. In order to conveniently install and fix the guide roller 1, a plurality of mounting seats 214 are provided on the conveyor belt 213. These mounting seats 214 are arranged in a first horizontal direction, ensuring the orderly arrangement and stable transmission of the guide roller 1 on the conveyor belt 213. The design of the mounting seats 214 enables the guide roller 1 to be firmly mounted thereon and can be easily disassembled when replacement is required.

[0062] When replacing the guide roller 1, firstly, the transmission member 212 is driven to rotate by the first driving mechanism 22, and the transmission member 212 drives the conveyor belt 213 and the guide roller 1 on the mounting seat 214 to rotate together. When the guide roller 1 to be replaced rotates to the position of the replacement window 12, the first driving mechanism 22 is stopped. Then, the guide roller 1 to be replaced is lifted from the mounting seat 214 by the lifting platform 31 of the jacking assembly 30, and slightly lowered to release the connection between the guide roller 1 and the mounting seat 214. Then, the old guide roller 1 can be removed from the replacement window 12, and the new guide roller 1 can be put in through the window, and then the new guide roller 1 can be lifted to the appropriate position by the jacking assembly 30, and reconnected with the mounting seat 214. Finally, the first driving mechanism 22 is started, and the transmission member 212 and the conveyor belt 213 are driven to rotate, and the new guide roller 1 is rotated back to the working position. At the same time, the end of the new guide roller 1 will abut on the connecting assembly 40, and realize electrical connection to ensure the normal operation of the dryer.

[0063] Further, refer to Figures 3 to 5In some embodiments of the present invention, the support frame 211 includes a first support rod 2111 and a second support rod 2112. The first support rod 2111 is extended along the second horizontal direction and is arranged in the box body of the drying box 11. The first support rod 2111 is located between the transmission members 212; the second support rod 2112 is extended along the first horizontal direction and is arranged on the first support rod 2111. A rolling member 2113 is arranged at one side end of the second support rod 2112. The rolling member 2113 is arranged along the first horizontal direction. The rolling member 2113 can abut against the transmission member 212 or the conveyor belt 213, and the rolling member 2113 can rotate in the second support rod 2112.

[0064] Specifically, the specific implementation of the support frame 211 is 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 is extended along the second horizontal direction and arranged in the box body of the drying box 11, and is located between the transmission member 212. Its main function is to provide a stable support base to ensure that the transmission member 212 can perform a smooth rotary motion thereon. The second support rod 2112 is extended along the first horizontal direction and arranged on the first support rod 2111. A plurality of rolling members 2113 are arranged at one side end of the second support rod 2112. These rolling members 2113 are arranged in an array along the first horizontal direction, and can abut against the transmission member 212 or the conveyor belt 213, that is, the rolling member located on the upper side can abut against the lower side of the transmission member 212, and the rolling member 2113 located on the lower side can be located at the lower side of the conveyor belt 213, for supporting the conveyor belt 213. The design of the rolling element 2113 can reduce friction and improve the rotation efficiency of the transmission element 212 or the conveyor belt 213 during the rotation process. At the same time, the rolling element 2113 can also rotate in the second support rod 2112 to further ensure 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 groove for connecting the transmission element 212. The transmission element 212 can be a chain or a transmission belt.

[0065] In the process of replacing the guide roller 1, the support frame 211 plays a particularly important role. When the first driving mechanism 22 drives the transmission member 212 to rotate, the transmission member 212 drives the rolling member 2113 to rotate on the second support rod 2112. This design not only reduces friction, but also improves the stability and efficiency of the rotation. At the same time, since the support frame 211 provides a stable support foundation, the transmission member 212 and the conveyor belt 213 can remain stable during the rotation process, thereby ensuring the stability and safety of the guide roller 1.

[0066] Specifically, refer to Figures 3 to 5In some embodiments of the present invention, the conveyor belt 213 includes a plurality of support plates 2131, which are arranged in sequence on the outer side of the transmission member 212, and the mounting seat 214 is arranged on the support plate 2131. The conveyor belt 213 is a key component of the rotary mechanism 21, and it is mainly responsible for supporting and conveying the guide roller 1. According to the design of the present invention, the conveyor belt 213 includes a plurality of support plates 2131, which are arranged in sequence on the outer side of the transmission member 212. The design of the support plate 2131 enables the conveyor belt 213 to support the guide roller 1 more stably and to perform a rotary motion smoothly under the drive of the transmission member 212. Mounting seats 214 are arranged on the support plate 2131. These mounting seats 214 are used to install the guide roller 1, which can firmly fix the guide roller 1 to ensure the stability and safety of the guide roller 1 during the rotation process. The design of the mounting seat 214 makes the replacement of the guide roller 1 more convenient, and only needs to be simply disassembled and installed.

[0067] In the process of replacing the guide roller 1, the role of the conveyor belt 213 is particularly critical. When the first drive mechanism 22 drives the transmission member 212 to rotate, the transmission member 212 will drive the support plate 2131 and the guide roller 1 on the mounting seat 214 to rotate together. This design allows the guide roller 1 to be easily rotated to the position of the replacement window 12, which is convenient for replacement operations. At the same time, since the support plate 2131 provides a stable support foundation, the guide roller 1 can remain stable during the rotation process, thereby ensuring the stability and continuity of the film coating process. In addition, the design of the conveyor belt 213 also makes the replacement of the guide roller 1 faster and more efficient. Simply remove the old guide roller 1 through the replacement window 12, and then install the new guide roller 1 on the mounting seat 214. This design greatly reduces the time and labor costs required to replace the guide roller 1.

[0068] Reference Figures 3 to 6 Furthermore, in some embodiments of the present invention, each group of mounting seats 214 includes a fixing seat 2141 and a locking seat 2142, and the fixing seat 2141 and the locking seat 2142 are arranged at both ends of the conveyor belt 213 along the second horizontal direction. Along the second horizontal direction, the fixing seat 2141 is located at the end away from the replacement window 12, and the locking seat 2142 is located at the end close to the replacement window 12. The fixing seat 2141 is used to support one end of the guide roller 1, and the locking seat 2142 is used to install and lock the other end of the guide roller 1.

[0069] Specifically, the specific implementation of the mounting seat 214 is as follows: the mounting seat 214 is a key component for mounting and fixing the guide roller 1 on the conveyor belt 213. According to the design of the present invention, each group of mounting seats 214 includes a fixing seat 2141 and a locking seat 2142, which are arranged at both ends of the conveyor belt 213 along the second horizontal direction. The fixing seat 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 to ensure that the guide roller 1 can remain stable during the rotation process. The design of the fixing seat 2141 allows one end of the guide roller 1 to be firmly fixed thereon to prevent the guide roller 1 from shaking or falling off during the rotation or working process. The locking seat 2142 is located at the end close 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 seat 2142 allows the other end of the guide roller 1 to be easily installed and disassembled, and at the same time ensures that the guide roller 1 can be firmly locked on the locking seat 2142 during the rotation and working process to maintain stability.

[0070] In the process of replacing the guide roller 1, the role of the mounting seat 214 is particularly critical. First, the transmission member 212 is driven to rotate by the first driving mechanism 22, and the guide roller 1 to be replaced is rotated to the position of the replacement window 12. Then, the lifting platform 31 of the jacking assembly 30 is used to slightly lift one end of the guide roller 1 from the locking seat 2142, and the locking state of the locking seat 2142 is released. Then, the old guide roller 1 can be removed from the replacement window 12, and the new guide roller 1 can be put in through the window, and the other end of the new guide roller 1 can be placed on the fixed seat 2141 using the jacking assembly 30, and then one end of the new guide roller 1 is installed on the locking seat 2142 and locked. Finally, the replacement of the guide roller 1 is completed. This design makes the replacement of the guide roller 1 faster and more efficient. Since the fixed seat 2141 and the locking seat 2142 are respectively located at the two ends of the conveyor belt 213 and are arranged along the second horizontal direction, the guide roller 1 can be easily replaced through the replacement window 12. At the same time, the design of the fixing seat 2141 and the locking seat 2142 also ensures the stability and safety of the guide roller 1 during the rotation and operation process.

[0071] Further, refer to Figure 6In some embodiments of the present invention, the locking seat 2142 includes a shaft seat 2142a and a shaft cover 2142b, the shaft seat 2142a is arranged on the conveyor belt 213, the shaft cover 2142b is rotatably arranged on the shaft seat 2142a, and a mounting hole 2142c is arranged between the shaft seat 2142a and the shaft cover 2142b, and the mounting hole 2142c is used to install 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, which is mainly responsible for installing and locking one end of the guide roller 1. According to the design of the present invention, the locking seat 2142 includes a shaft seat 2142a and a shaft cover 2142b. The shaft seat 2142a is arranged on the conveyor belt 213, which provides a stable support base for installing one end of the guide roller 1. The design of the shaft seat 2142a ensures that the guide roller 1 can remain stable and stable after installation. The shaft cover 2142b is rotatably disposed on the shaft seat 2142a. This design allows the shaft cover 2142b to be opened when necessary in order to install or remove the guide roller 1. At the same time, the shaft cover 2142b can also be firmly locked on the shaft seat 2142a after the guide roller 1 is installed to prevent 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 install one end of the guide roller 1. The design of the mounting hole 2142c ensures that the guide roller 1 can be accurately installed on the locking seat 2142 and maintain a stable connection.

[0072] In the process of replacing the guide roller 1, the role of the locking seat 2142 is particularly critical. First, the transmission member 212 is driven to rotate by the first driving mechanism 22, and the guide roller 1 to be replaced is rotated to the position of the replacement window 12. Then, the shaft cover 2142b is opened by a tool or manual operation, and one end of the guide roller 1 is taken out from the mounting hole 2142c. Then, the old guide roller 1 can be removed from the replacement window 12, and the new guide roller 1 can be put in through the window, so that one end of the new guide roller 1 is aligned with the mounting hole 2142c and installed. Finally, the shaft cover 2142b is closed and locked on the shaft seat 2142a to complete the replacement of the guide roller 1. This design makes the replacement of the guide roller 1 faster and more convenient. Since the shaft cover 2142b is rotatably arranged on the shaft seat 2142a, it can be easily opened and closed, thereby simplifying the replacement process of the guide roller 1. At the same time, the design of the mounting hole 2142c also ensures that the guide roller 1 can be accurately mounted on the locking seat 2142 and maintain a stable connection, thereby improving the production efficiency and product quality of the thin film coating production line.

[0073] Reference Figures 3 to 5In some embodiments of the present invention, the first driving mechanism 22 includes a driving member 221, a driving wheel group 222, and a driven wheel group 223. The driving member 221 is disposed on the support frame 211; the driving wheel group 222 is rotatably disposed in the body of the drying box 11, the output end of the driving member 221 is connected to the driving wheel group 222, the driving member 221 drives the driving wheel group 222 to rotate, and the transmission member 212 is wound around the driving wheel group 222; along the second horizontal direction, the driven wheel group 223 is rotatably disposed at the other end of the body of the drying box 11, the transmission member 212 is wound around the driven wheel group 223, and the transmission member 212 drives the driven wheel group 223 to rotate.

[0074] In some embodiments, the specific implementation of the first driving mechanism 22 is as follows: the first driving mechanism 22 is the power source of the rotary mechanism 21, and it is mainly responsible for driving the transmission member 212 to perform a rotary motion. According to the design of the present invention, the first driving mechanism 22 includes a driving member 221, a driving wheel group 222 and a driven wheel group 223. The driving member 221 is arranged 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 group 222 to rotate. The driving wheel group 222 can be rotatably arranged in the housing of the drying box 11. The output end of the driving member 221 is connected to the driving wheel group 222. When the driving member 221 is started, it drives the driving wheel group 222 to rotate. The transmission member 212 is arranged around the driving wheel group 222, so that when the driving wheel group 222 rotates, it drives the transmission member 212 to perform a rotary motion together. The driven wheel group 223 is rotatably arranged at the other end of the housing of the drying box 11 along the second horizontal direction. The transmission member 212 is also wound around the driven wheel set 223. When the transmission member 212 is driven by the driving wheel set 222 to perform a rotational motion, it will simultaneously drive the driven wheel set 223 to rotate. This design ensures the stability and balance of the transmission member 212 during the rotation process.

[0075] In the process of replacing the guide roller 1, the role of the first driving mechanism 22 is particularly critical. First, the driving member 221 is started, which will output power and drive the driving wheel group 222 to rotate. Then, the driving wheel group 222 will drive the transmission member 212 to perform a rotational motion. Since the transmission member 212 is wound around the driving wheel group 222 and the driven wheel group 223 at the same time, when the transmission member 212 performs a rotational motion, it will also drive the driven wheel group 223 to rotate. This design allows the transmission member 212 to remain stable and stable during the rotation process, thereby ensuring the stability and safety of the guide roller 1 during the replacement process. At the same time, since the first driving mechanism 22 provides sufficient power to drive the transmission member 212 to perform a rotational motion, the efficiency and convenience of replacing the guide roller 1 are also improved. The first driving mechanism 22 of the coating dryer guide roller 1 quick replacement device realizes the smooth rotational movement of the transmission member 212 through the ingenious design of the driving member 221, the driving wheel group 222 and the driven wheel group 223, further improving the maintenance efficiency and production continuity of the thin film coating production line.

[0076] Reference Figures 3 to 5 In some embodiments of the present invention, the lifting assembly 30 further includes a slide 32 and a lifting mechanism 33. The slide 32 can be slidably arranged on the body of the drying box 11, and the slide 32 slides along the second horizontal direction; the lifting mechanism 33 is arranged on the slide 32, and the lifting platform 31 is arranged on the slide 32 through the lifting mechanism 33. The lifting mechanism 33 includes a guide rod 331 and a driving assembly 332. The guide rod 331 is vertically arranged on the slide 32, and the lifting platform 31 is sleeved on the guide rod 331. The driving assembly 332 is arranged between the slide 32 and the lifting platform 31, and the driving assembly 332 is used to drive the lifting platform 31 to move up and down in the vertical direction.

[0077] In some embodiments, the specific implementation of the lifting assembly 30 is as follows: the lifting assembly 30 is an important part of the quick replacement device of the guide roller 1 of the coating dryer, and it is mainly responsible for slightly lifting the guide roller 1 from the conveyor belt 213 for replacement operation. According to the design of the present invention, the lifting assembly 30 includes a slide 32 and a lifting mechanism 33 in addition to the lifting platform 31. The slide 32 can be slidably arranged on the box body of the drying box 11 and slide along the second horizontal direction. This design enables the slide 32 to move to a specified position when necessary to lift the guide roller 1. The lifting mechanism 33 is arranged on the slide 32, and the lifting platform 31 is arranged on the slide 32 through the lifting mechanism 33. The main function of the lifting mechanism 33 is to drive the lifting platform 31 to move up and down in the vertical direction so as to slightly lift the guide roller 1 from the conveyor belt 213. The lifting mechanism 33 specifically includes a guide rod 331 and a driving assembly 332. The guide rod 331 is vertically arranged on the slide 32, and it provides a guiding function for the lifting platform 31 to move up and down. The lifting platform 31 is sleeved on the guide rod 331, so that when the driving component 332 is working, the lifting platform 31 can move up and down stably along the guide rod 331. The driving component 332 is arranged between the slide 32 and the lifting platform 31, and it provides the power required for the lifting platform 31 to move up and down. When it is necessary to lift the guide roller 1, the driving component 332 works, drives the lifting platform 31 to rise in the vertical direction, and slightly lifts the guide roller 1 from the conveyor belt 213. After completing the replacement operation, the driving component 332 drives the lifting platform 31 to descend and return to its original position.

[0078] This design makes the replacement of the guide roller 1 faster and more convenient. Since the lifting assembly 30 can easily lift the guide roller 1 slightly from the conveyor belt 213, the replacement operation process can be greatly simplified. At the same time, since the lifting and lowering movement of the lifting platform 31 is achieved by the lifting mechanism 33, the stability and safety of the lifting process are also ensured. It should be noted that the above-mentioned drive assembly 332 can be a hydraulic cylinder lifting drive or a pneumatic cylinder lifting drive, or a gear rack push drive, which is not specifically limited in this embodiment.

[0079] Reference Figure 3 to Figure 4 as well as Figure 6 to Figure 7In some embodiments of the present invention, the connection assembly 40 includes: a guide slide 41 and an electrical connection seat 42. The guide slide 41 can be movably arranged on the inner side wall of the box body of the drying box 11, and a limiting slide groove 411 is arranged on one side of the guide slide 41. The limiting slide groove 411 extends along the first horizontal direction, and one end of the guide roller 1 can slide in the limiting slide groove 411. The limiting slide groove 411 is provided with a mounting slot 412, and the mounting slots 412 are arranged at intervals along the first horizontal direction. The positions of the mounting slots 412 are arranged one by one corresponding to the positions of the guide roller 1; there are multiple electrical connection seats 42, and the electrical connection seats 42 are slidably arranged in the mounting slots 412 through elastic members 423. The mounting slots 412 are provided with ejectors 421, and the ejectors 421 can be inserted into the electrical connection seat 42, and one end of the ejectors 421 is electrically connected to the outside, and the other end of the ejectors 421 is used to abut against the end of the guide roller 1, and the ejectors 421 are electrically connected to the guide roller 1.

[0080] Specifically, in some embodiments, the specific implementation of the connection assembly 40 is as follows: the connection assembly 40 is an important part of the quick replacement device of 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 body of the drying box 11. According to the design of the present invention, the connection assembly 40 includes a guide slide 41 and an electrical connection seat 42.

[0081] The guide slide 41 can be movably arranged on the inner side wall of the box body of the drying box 11. A limiting slide groove 411 is arranged on one side thereof, and the limiting slide groove 411 extends along the first horizontal direction. In this way, when the guide roller 1 needs to be replaced, one end of the guide roller 1 can be placed in the limiting slide groove 411 and made to slide along the first horizontal direction. In the limiting slide groove 411, a mounting slot 412 is arranged. These mounting slots 412 are arranged at intervals along the first horizontal direction, and their positions are arranged one by one corresponding to the positions of the guide rollers 1. In this way, each guide roller 1 has a corresponding mounting slot 412 to install the electrical connection seat 42. There are multiple electrical connection seats 42, which are slidably arranged in the mounting slot 412 through the elastic member 423. In this way, when the end of the guide roller 1 is placed in the limiting slide groove 411 and slides to the corresponding mounting slot 412 position, the electrical connection seat 42 can be in close contact with the end of the guide roller 1 under the action of the elastic member 423. In the installation slot 412, there is also a pin 421. The pin 421 can be inserted into the electrical connection seat 42, and one end of the pin is electrically connected to the outside world, and the other end is used to abut the end of the guide roller 1. In this way, when the electrical connection seat 42 is in close contact with the end of the guide roller 1, the pin 421 can transfer external electrical energy to the guide roller 1, thereby realizing the electrical connection between the guide roller 1 and the drying box 11. It should be noted that transition fillets should be provided on both sides of the electrical connection seat 42 in the first horizontal direction to facilitate the guide roller 1 to slide to the top of the electrical connection seat 42 and squeeze the electrical connection seat 42 to the right.

[0082] In the process of replacing the guide roller 1, the role of the connection assembly 40 is particularly critical. First, one end of the replaced guide roller 1 is driven by the transmission assembly 20, slides from one end of the guide slide 41 into the limiting slide groove 411, and slides along the first horizontal direction. Then, when the end of the guide roller 1 slides to the corresponding installation slot 412 position, the guide roller 1 squeezes the electrical connection seat 42, so that the electrical connection seat 42 slides in the installation slot 412, and at the same time, the electrical connection seat 42 is in close contact with the end of the guide roller 1 under the action of the elastic member 423. Next, the guide slide 41 is driven by a driving device (not shown) to approach the guide roller 1. At this time, the bottom of the mounting slot 412 of the guide slide 41 further squeezes the elastic member 423, and the ejector pin 421 slides in the electrical connection seat 42, so that one end of the ejector pin 421 can abut against the contact point at the end of the guide roller 1, so the ejector pin 421 can transfer external electrical energy to the guide roller 1, realize the electrical connection between the guide roller 1 and the drying box 11, and provide a power source for the rotation of the guide roller 1. This design makes the replacement and electrical connection of the guide roller 1 faster and more convenient. Through the transmission component 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 connection seat 42 is slidably arranged in the mounting slot 412 by the elastic member 423, it can also ensure the close contact and stable electrical connection between the guide roller 1 and the electrical connection seat 42.

[0083] Further, refer to Figure 6 to Figure 7 In some embodiments of the present invention, a sealing ring 422 is provided at the end of the electrical connection seat 42 and / or the end of the guide roller 1. In the coating and drying machine guide roller 1 quick replacement device, the electrical connection stability and dustproof and waterproof performance between the electrical connection seat 42 and the guide roller 1 are crucial. Therefore, according to the design of the present invention, a sealing ring 422 is provided at the end of the electrical connection seat 42 and / or the end of the guide roller 1.

[0084] The sealing ring 422 is usually made of an elastic material, such as rubber or silicone. When the electrical connection seat 42 is in close contact with the end of the guide roller 1, the sealing ring 422 can effectively fill the small gap between the two, thereby preventing dust, moisture or other impurities from entering the electrical connection part, and ensuring the stability and reliability of the electrical connection. One or more sealing rings 422 can be set at the end of the electrical connection seat 42. These sealing rings 422 can fit tightly on the end face of the electrical connection seat 42 to ensure that a good sealing effect can be formed when contacting the end of the guide roller 1. Similarly, one or more sealing rings 422 can also be set at the end of the guide roller 1. These sealing rings 422 can fit tightly on the end face of the guide roller 1 to form a seal when contacting the end of the electrical connection seat 42.

[0085] The material of the sealing ring 422 should have good elasticity, wear resistance and corrosion resistance to ensure its stability and durability during long-term use. Common materials of the sealing ring 422 include rubber, silicone, polyurethane, etc. The main function of the sealing ring 422 is to prevent dust, moisture or other impurities from entering the electrical connection part to ensure the stability and reliability of the electrical connection. At the same time, the sealing ring 422 can also play a certain buffering role, reducing the impact and vibration between the electrical connection seat 42 and the end of the guide roller 1, thereby extending the service life.

[0086] Reference Figure 1 to Figure 2 According to the coating dryer of the second aspect of the present invention, the coating dryer includes the coating dryer guide roller replacement device 3 of any one of the embodiments of the first aspect. The coating dryer cleverly integrates multiple functions such as coating, drying and quick replacement of guide roller 1 in structure. The quick replacement device of the guide roller 1 of the coating dryer simplifies the replacement process of the guide roller 1, thereby reducing the maintenance time and improving the overall operation efficiency of the production line. Therefore, it can be understood that the coating dryer according to the embodiment of the present invention has at least the following beneficial effects: the coating dryer transmits the guide roller 1 to the replacement window 12 on the box body of the drying box 11 through the rotating mechanism 21, and the technician opens the replacement window 12. After the guide roller 1 is removed, the new guide roller 1 replaced can be installed on the rotating mechanism 21 through the lifting assembly 30. Under the rotation of the rotating mechanism 21, the guide rollers 1 can be replaced one by one, so that the newly replaced guide rollers 1 are clean and free of adhered paint, and different models of guide rollers 1 can also be replaced to meet different film coating production requirements.

[0087] Reference Figure 1 to Figure 2 In some embodiments of the present invention, the coating dryer further comprises a drying device 2, which is arranged in the body of the drying box 11 and located above the coating dryer guide roller replacement device 3, and the drying device 2 is used to dry the coated film. The present invention is further equipped with a drying device 2, which is arranged inside the body of the drying box 11 and located above the coating dryer guide roller 1 quick replacement device. Its main function is to dry the film after coating.

[0088] The drying device 2 can be composed of a series of efficient and energy-saving drying elements, such as heating elements, hot air circulation systems, etc., which work together to ensure that the film can be quickly and evenly dried after coating. The drying device 2 uses advanced heating and hot air circulation technology to ensure that the film achieves the desired drying effect in a short time. Through the precisely controlled drying process, the drying device 2 can ensure that all parts of the film obtain a uniform drying effect, thereby avoiding quality problems caused by uneven drying. While providing efficient drying performance, the drying device 2 also focuses on energy conservation and environmental protection, and adopts a number of energy-saving technologies and measures to reduce energy consumption and emissions.

[0089] Therefore, it is understandable that the coating dryer combined with the coating dryer guide roller 1 quick replacement device and the high-efficiency drying device 2 has shown significant advantages in production efficiency, operation convenience, product quality and energy utilization. This innovative design not only improves the overall performance of the film coating production line, but also brings higher economic and environmental benefits to users.
