Preferably, as shown in fig. 1 and fig. 2, the coating machine further includes a transition roller b12, the transition roller b12 is disposed below the first position and between the roller 51 and the deviation correcting mechanism 7, when the second coating roller 31 is located at the first position, the tape 100 is wound around the second coating roller 31 after being wound around the side of the transition roller b12 facing away from the second coating roller 31, and when the second coating roller 31 is located at the second position, the tape 100 is wound around the lower side of the transition roller b12 and is wound around the roller 51 from the side of the transition roller b12 facing the first coating roller 2. That is, the transition roller b12 is disposed at the above position, and the tape is wound from different positions of the transition roller b12 under different coating modes, so that the tape 100 can be wound around the transition roller a11 or the over roller 51 respectively in an appropriate direction, and further, the tape 100 can have an appropriate wrap angle on the corresponding traction roller under both coating modes, thereby improving the coating effect. Preferably, when blade coating is performed, the lowest point of the tape 100 wound around the transition roller b12 is lower than the highest point of the deviation rectifying mechanism 7, so as to ensure the tension state of the tape 100 and prevent the tape 100 from being loosened from the transition roller b 12. In the present example, when second applicator roll 31 is in the first position, transition roll b12 is located just below transition roll a 11.
Further, the coating machine further comprises a swing roller mechanism 8, the swing roller mechanism 8 is arranged on the rack 1 and located below the first coating roller 2, the material belt 100 is wound on the transition roller b12 or the deviation correcting mechanism 7 after being wound on the swing roller mechanism 8, the swing roller mechanism 8 is used for adjusting the tension of the material belt 100, the material belt 100 is guaranteed to be kept in a stretched and flat state in the coating process, and the coating effect is improved. The basic working principle of the oscillating roller mechanism 8 is that the material strip 100 is wound around an oscillating intermediate roller, and the intermediate roller performs position oscillation adjustment according to the tension state of the material strip 100, so that the material strip 100 maintains a preset tension value. The oscillating roller mechanism 8 is a part existing in the prior art, and the specific structure thereof is not described in detail herein. In this embodiment, the oscillating roller mechanism 8 is located below the first coating roller 2 and is biased to the side away from the second coating roller 31.
Preferably, the coating machine further includes a transition roller c13, the transition roller c13 is disposed between the deviation rectifying mechanism 7 and the swing roller mechanism 8 and below the transition roller b12, when the second coating roller 31 is located at the first position, the material tape 100 is wound around the transition roller b12 from the swing roller mechanism 8 through the transition roller c13, and when the second coating roller 31 is located at the second position, the material tape 100 is wound around the deviation rectifying mechanism 7 from the swing roller mechanism 8 through the transition roller c 13. That is, when the coater is in the gap coating mode, the transition roller c13 can adjust the direction of the tape 100 before the transition roller b12 is wound, that is, the transition roller c13, the transition roller b12 and the transition roller a11 cooperate together to adjust the wrap angle of the tape 100 on the second coating roller 31. During the blade coating mode, the transition roller c13 can adjust the trend of the material belt 100, ensure that the material belt 100 leaves the swing roller mechanism 8 and then smoothly enters the deviation rectifying mechanism 7, and ensure the tension state of the material belt 100. In this embodiment, the highest point of the tape 100 wound on the transition roller c13 is lower than the lowest point wound on the deviation correcting mechanism 7, so as to ensure the tension state of the tape 100 and prevent the tape 100 from loosening from the transition roller c 13. That is to say, the present application makes the tape-moving form of the material tape 100 switchable according to the coating form through the arrangement of the transition roller b12 and the transition roller c13, so as to improve the coating efficiency and effect. The positions of the transition roller b12 and the transition roller c13 can be adjusted according to actual needs under the condition that the coating wrap angle requirement of the material belt 100 is met.
Preferably, the transition roller b12 and the transition roller c13 are movable structures so as to further improve the smoothness of the belt; any known movable structure can be used in the present application without departing from the inventive concept of the present application, and will not be described herein.
In summary, because the requirement for deviation rectification is low in the gap coating process, the tape 100 is sequentially fed from the swing roller mechanism 8, the transition roller c13 and the side departing from the second coating roller 31 from the transition roller b12, and then sequentially fed through the gap between the transition roller a11, the first coating roller 31 and the second coating roller 2; in the blade coating process, the second coating roller 31 and the transition roller a11 do not participate in the coating process any more, so the material tape 100 passes through the oscillating roller mechanism 8, the transition roller c13, the deviation correcting mechanism 7, the transition roller b12, the transition roller b12, the side close to the first coating roller 2, the transition roller b 3526, the roll over the roller 51 and the first coating roller 2.
According to the characteristics of the gap coating and the scraper coating, the deviation correcting mechanism is selected to be arranged during the scraper coating, so that the precision requirement of the scraper coating is met, the deviation correcting mechanism 7 is utilized to realize the tape moving adjustment of the material tape 100, the gap coating and the scraper coating are switched stably, and the coating machine can work stably under two modes.
In the present invention, the tape transport rollers such as the transition roller and the over roller may be a single roller, or may be a set of rollers that perform corresponding functions, for example, the transition roller a11 may be a single roller, or may be three small rollers, as long as the adjustment of the angle of the tape 100 entering the second coating roller 31 or the first coating roller 2 can be achieved. For those skilled in the art, the technical solution formed by the separation and combination of the rolls with the same functions is within the protection scope of the claims of the present invention.
Preferably, as shown in fig. 3, the coater further includes a third driving assembly for driving the second coating roller 31 to rotate, the third driving assembly is disposed on the frame 1, and an output end of the third driving assembly is detachably connected to the second coating roller 31. When second coating roller 31 is located at the first position, the third driving component is connected with second coating roller 31 to ensure that second coating roller 31 can be normally driven, and when second coating roller 31 is located at the second position, the third driving component is separated from second coating roller 31, so that the third driving component does not need to be switched along with second coating roller 31, and the problem of winding of an electric wire or a signal wire connected with the third driving component can be avoided. In this embodiment, the third driving component may be a speed reducing motor, and the speed reducing motor is connected with the second coating roller 31 through a coupling. In other embodiments, the third driving assembly may also be other assemblies or components capable of outputting a rotational motion, and is not limited in particular herein.
