[0020] Please refer to Figures 1 to 4 In the embodiment of the present application, a coating machine drying device comprises a drying box 1 having groove bodies 5 at two ends, one groove body 5 is used for feeding, and the other groove body 5 is used for discharging. Auxiliary supporting mechanisms are installed on both sides of the end plate of the drying box 1. A synchronous mechanism movably connected with the auxiliary supporting mechanisms is installed at one end of the drying box 1. Two groups of fixing ears are fixedly connected to both sides of the end plate of the drying box 1. One group of fixing ears comprises four rotating seats 4, which are distributed in a rectangular shape. The auxiliary supporting mechanisms are rotatably connected with the rotating seats 4. The auxiliary supporting mechanisms comprise swing arms 9 rotatably connected with the rotating seats 4. Two swing arms 9 located on the same horizontal plane are rotatably installed with supporting rollers 8 at the ends away from the rotating seats 4.

[0021] In the embodiment, after the base material is coated with glue, it enters the drying box 1 through the groove body 5 at one end for drying. After drying, it is moved out of the drying box 1 through the groove body 5 at the other end. The drying box 1 is a suspended drying box. A plurality of drying nozzles are installed on the inner wall of the drying box 1 in a staggered manner. The hot air flow blown out by the drying nozzles can achieve a supporting effect on the base material coated with glue. At this time, the base material coated with glue is in a wave state in the drying box. Due to this wave state, the auxiliary supporting structures need to be arranged at the feeding groove body 5 and the discharging groove body 5 to avoid hard contact between the base material and the groove body 5, which may cause damage to the glue on the base material.

[0022] When the thickness of the base material or the thickness of the glue coating changes, the synchronous mechanism is started. The synchronous mechanism drives the two supporting rollers 8 at one end to rotate towards or away from each other to adapt to base materials of different thicknesses or glue coatings of different thicknesses.

[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4The synchronous mechanism comprises a movable groove 10 formed in the inside of the swing arm 9, the movable groove 10 is distributed along the length direction of the swing arm 9, the inner wall of the movable groove 10 is slidably connected with a movable column 11, one end of two movable columns 11 located in the same vertical plane is fixedly installed with a connecting plate 12, the synchronous mechanism further comprises a lower moving arm 7 and an upper moving arm 13, the lower moving arm 7 and the upper moving arm 13 are symmetrically distributed in the up-down direction, one end of the upper moving arm 13 is fixedly connected with one connecting plate 12, one end of the lower moving arm 7 is fixedly connected with the other connecting plate 12, the fixed point of the upper moving arm 13 is located in the inner cavity of the drying box 1, one end of the upper moving arm 13 away from the fixed point penetrates through the drying box 1 and extends to the outside of the drying box 1, the outer wall of the lower moving arm 7 is slidably connected with a limiting block 6, the limiting block 6 is fixedly connected with the outside of the drying box 1, the synchronous mechanism further comprises two telescopic arms 15 fixedly connected with the non-fixed point end of the upper moving arm 13 and the lower moving arm 7, the inner wall of each telescopic arm 15 is slidably connected with a rotating arm 14, the circular plate part at the center of the rotating arm 14 is rotatably connected with the drying box 1.

[0024] In the embodiment, when the synchronous mechanism operates, at this time, the electric push cylinder 2 operates, the operating electric push cylinder 2 pushes the lower moving arm 7 connected with the electric push cylinder 2 to move, the non-fixed end of the lower moving arm 7 drives the one end of the telescopic arm 15 connected with the non-fixed end to synchronously move, the telescopic arm 15 drives the rotating arm 14 to rotate, at this time, the overlapping area of the telescopic arm 15 and the rotating arm 14 changes, the two connecting plates 12 located in the same end move towards each other or move away from each other, the moving connecting plate 12 drives the movable column 11 to slide in the movable groove 10, at this time, the four swing arms 9 located at the two ends of the upper and lower supporting rollers 8 rotate around the rotating seat 4 connected with the four swing arms 9 respectively, therefore, the distance between the two supporting rollers 8 located in the upper and lower positions changes, the adaptive adjustment purpose is achieved.
