[0029] like Figures 1 to 7 As shown, the automotive sealing strip coiling device of the present invention comprises a winding mechanism 1, a moving mechanism 2, a guiding mechanism 3 and a bending mechanism 4. The winding mechanism 1 comprises a roller 14, and the roller 14 can rotate to wind up the sealing strip. The moving mechanism 2 is connected to the winding mechanism 1, and the guiding mechanism 3 is connected to the moving mechanism 2. The guiding mechanism 3 can guide the sealing strip. The moving mechanism 2 can drive the guiding mechanism 3 to move forward and backward so that the sealing strip is evenly wound on the winding mechanism 1. The bending mechanism 4 is connected to the guiding mechanism 3. The bending mechanism 4 can bend the sealing strip upward when the sealing strip is wound to the inner edge of the roller 14, so that the width of the sealing strip becomes smaller, thereby avoiding friction between the sealing strip and the inner wall of the roller 14.

[0030] like Figure 1 and Figure 2 As shown, the winding mechanism 1 includes a driving box 11, a rotating shaft 12, a baffle 13 and a baffle 2 15. The rotating shaft 12 is rotatably connected to the front side of the driving box 11. A motor (not shown in the figure) is connected to the driving box 11. The output shaft of the motor is connected to the rotating shaft 12. The baffle 13 is connected to the outer rear end of the rotating shaft 12. The roller 14 is sleeved on the rotating shaft 12, and the rear side of the roller 14 is in contact with the front side of the baffle 13. A threaded section is provided at the outer front end of the rotating shaft 12. The baffle 2 15 is threadedly connected to the threaded section at the outer front end of the rotating shaft 12, and the rear side of the baffle 2 15 is in close contact with the front side of the roller 14.

[0031] The motor in the driving box 11 is started to drive the rotating shaft 12 to rotate, and the baffle plate 1 13 , the roller 14 and the baffle plate 2 15 are driven to rotate by the rotating shaft 12 , and the sealing strip is rolled up by the roller 14 .

[0032] like Figures 1 to 4 As shown, the guide mechanism 3 includes a mounting portion 31, a lifting portion 32, a driving source 1 33, a screw rod 34, a guide roller 1 35 and a guide roller 2 36. The mounting portion 31 is connected to the moving mechanism 2, and the moving mechanism 2 can drive the mounting portion 31 to move forward and backward. The lifting portion 32 is limitedly slidably connected to the front side of the mounting portion 31, and the driving source 1 33 is connected to the rear side of the mounting portion 31. The driving source 1 33 is a motor. The bottom end of the screw rod 34 is connected to the output shaft of the driving source 1 33, and the top end of the screw rod 34 is rotatably connected to the mounting portion 31. The guide roller 1 35 and the guide roller 2 36 are connected to the guide roller 36. Both guide roller one 35 and guide roller two 36 are rotatably connected to the lifting part 32.

[0033] The sealing strip passes through three guide rollers 1 35 and two guide rollers 2 36 in sequence and is wound around the drum 14. When the drum 14 rotates and reels the sealing strip, the three guide rollers 1 35 and two guide rollers 2 36 guide the sealing strip to avoid the sealing strip from being wound. The moving mechanism 2 is started, and the moving mechanism 2 drives the guide mechanism 3 to move back and forth, so that the sealing strip is evenly reeled on the drum 14. At the same time, the driving source 1 33 drives the screw rod 34 to rotate, and the screw rod 34 drives the lifting part 32 to move up intermittently, so that every time the sealing strip is reeled in a layer in the drum 14, the lifting part 32 will move upward for a distance, so that the sealing strip between the guide mechanism 3 and the drum 14 is in a horizontal state, so that the bending mechanism 4 can be bent on the sealing strip.

The second driving source 418 is started to drive the transmission structure 419 to drive one of the rotating shafts 415 to rotate. At this time, the two gears 417 are driven to engage and transmit, so that the two rotating shafts 415 rotate in the opposite direction, and the two supporting frames 414 are driven to flip upward in the opposite direction. Under the guidance of the guide 42, the sealing strip is bent upward to reduce the width of the sealing strip to avoid friction between the sealing strip and the inner wall of the drum 14.

[0037] When the sealing strip is rolled up to the inner edge of the drum 14, the driving source 418 is started to drive the transmission structure 419 to drive one of the rotating shafts 415 to rotate. At this time, the two gears 417 are driven to engage and transmit, so that the two rotating shafts 415 rotate in opposite directions, and the two support frames 414 are driven to flip upward in the opposite direction. Under the guidance of the guide 42, the sealing strip is bent upward, and the driving part 412 is started to pull the mounting frame 413 to move in the direction away from the drum 14 to avoid the mounting part 31 from blocking the subsequent rolling of the sealing strip.

[0039] When the support frame 414 flips upward, the top of the sealing strip is blocked by the guide structure 428 to make the sealing strip bend upward. When the mounting frame 413 is away from the drum 14, the driving source three 425 drives the rotating part two 426 to rotate, and the connecting belt 427 is rolled up through the rotating part two 426, so that the connecting belt 427 pulls the rotating part one 424 and the plug-in part 4232 away from the drum 14, and squeezes the elastic part 4233 to avoid obstruction to the subsequent rolling of the sealing strip.

[0040] Working principle:

[0042] When the sealing strip is rolled up to the inner edge of the drum 14, the driving source 2 418 is started to drive the transmission structure 419 to operate, so as to drive one of the rotating shafts 415 to rotate.

[0043] The driving source 1 33 is started to drive the screw rod 34 to rotate, and the screw rod 34 drives the lifting part 32 to move upward intermittently, so that every time the sealing strip is rolled up one layer in the drum 14, the lifting part 32 will move upward a certain distance, so that the sealing strip between the guide mechanism 3 and the drum 14 is in a horizontal state.
