[0031] See also Figure 1-Figure 7 , the utility model provides the following technical solutions:

[0032] Embodiment 1: In order to solve the problem that the coating machine currently on the market needs to limit the material when feeding the material through the feeding roller, so as to facilitate the movement of the material driven by the feeding roller. When the material is used up, a replacement mechanism is needed to replace the material stably. However, the operation of the above device is cumbersome when replacing the material roll. Please refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 6 and attached Figure 7, including a frame 1, a control panel 2 is installed on one side of the frame 1, and a coating roller 3 is installed on the left side of the frame 1; it also includes: a feed roller 4 is installed on the right side of the frame 1, a group of receiving rollers 5 are rotatably arranged below the feed roller 4, and a tensioning roller 6 is rotatably arranged in the middle of the frame 1; the inner sides of the feed roller 4 and the receiving roller 5 are fitted on the outer side of the replacement mechanism, and the replacement mechanism includes a connecting rod 10 rotatably connected to one side of the frame 1, a group of rotating screw rods 11 are rotatably connected to the outer side of the connecting rod 10, a group of moving sleeves 12 are threadedly connected to the inner side of the rotating screw rod 11, and the outer side of the moving sleeve 12 is fitted on one side of the expansion airbag 13, one end of the outer side of the expansion airbag 13 is connected to one end of the fitting airbag 14 through a pipeline, and the outer side of the fitting airbag 14 is fixed with a limiting block 15 at equal angles. First, when replacing the feed roller 4 and the receiving roller 5, the rotating screw 11 on one side of the connecting rod 10 is rotated so that the rotating screw 11 rotates inside one end of the connecting rod 10. At this time, the movable sleeve 12 threadedly connected to the rotating screw 11 will slide inside the connecting rod 10 through the protrusion, so that the movable sleeve 12 squeezes one side of the expansion airbag 13 during the sliding process, causing the internal gas of the expansion airbag 13 to be transported to the inside of the bonding airbag 14 through the pipeline. At this time, the bonding airbag 14 will expand, so that the bonding airbag 14 is bonded to the inner side of the feed roller 4 and the receiving roller 5. Conversely, the bonding airbag 14 can also be detached from the inner side of the feed roller 4 and the receiving roller 5, so that the feed roller 4 and the receiving roller 5 can be replaced.

[0033] Embodiment 2: In order to ensure the coating of the coil, please refer to the attached Figure 1 -Attached Figure 3 The connecting rod 10, the coating roller 3 and one side of the tensioning roller 6 are all fixedly installed at the output end of a group of motors. One side of the tensioning roller 6 is rotatably set on the inner side of the connecting sleeve 8. The outer side of the connecting sleeve 8 is fixed on one side of the electric push rod 7. One side of the electric push rod 7 is fixed on the inner wall of the frame 1. A protrusion is set on the outer side of the movable sleeve 12. The materials of the expansion airbag 13 and the bonding airbag 14 are both elastic rubber. The limit block 15 fixed on the outer side of the bonding airbag 14 forms a sliding structure between the bonding airbag 14 and the inside of the connecting rod 10, and the top outer side of the bonding airbag 14 extends out of the outside of the connecting rod 10. During the coating process, the control panel 2 is used to control the motor inside the frame 1 to work. The motor drives the connecting rod 10, the tensioning roller 6 and the shaft end of the coating roller 3 on one side of the frame 1 to rotate inside the frame 1, so that the coating roller 3 can be rotated for coating processing, and the electric push rod 7 can drive the connecting sleeve 8 to move, so that the tensioning roller 6 rotatably connected to the inner side of the connecting sleeve 8 moves inside the frame 1, thereby adjusting the tension of the material to facilitate the coating process.

[0034] Example 3: In order to dry the coated coil, please refer to the attached Figure 3 and attached Figure 5 A drying box 9 for drying after coating is fixed at the lower position of the frame 1 near the tension roller 6. The drying box 9 includes heat conduction holes 901 opened at the upper and lower ends of the drying box 9, a group of heaters 902 are fixed at the internal position of the drying box 9, and a group of fixed motors 903 are fixedly installed at one side of the bottom of the drying box 9. The output end of the fixed motor 903 is fixed at one side of the reciprocating screw rod 904, and the outer position of the reciprocating screw rod 904 is threadedly connected to the bottom shell of the driving blade 905. The bottom two ends of the driving blade 905 are slidably set on the outside of the guide rod 906. The two ends of the guide rod 906 are fixed at the bottom position of the drying box 9, and the driving blade 905 forms a sliding structure through the reciprocating screw rod 904 and the guide rod 906. The top position of the driving blade 905 corresponds to the heat conduction hole 901 at the bottom of the drying box 9 and the bottom position of the heater 902. During the drying process, the heater 902 is started, and the heater 902 dries the inside of the drying box 9. The output end of the fixed motor 903 is started to drive the reciprocating screw 904 to rotate. At this time, the outer side of the reciprocating screw 904 drives the threaded driving blade 905 to move. The driving blade 905 will slide on the outer side of the guide rod 906. The driving blade 905 will guide the hot air from the heater 902 through the heat conduction hole 901, so that the hot air can dry the coated material.
