Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0017] This application provides an automatic winding device for car wrap film, such as... Figure 1 As shown, the automatic winding device 100 includes a storage device 10, a cutting and winding device 20 and a winding device 30 arranged sequentially from front to back. The car wrap film passes through the storage device 10 and the cutting and winding device 20 sequentially from front to back and is wound up on the winding device 30.

[0018] The storage device 10 includes several storage rollers 1 that can move up and down, arranged alternately from front to back. The upper and lower storage rollers 1 are spaced far apart, increasing the movement path of the car wrap film within the storage device 10 and achieving temporary storage. Conversely, the upper and lower storage rollers 1 are close together, decreasing the movement path of the car wrap film within the storage device 10 and releasing the temporarily stored film. The storage device 10, in conjunction with the winding sensor 30, performs material storage and unloading, enabling online winding without machine shutdown.

[0019] The rear end of the storage device 10 is provided with an auxiliary traction component 2. The auxiliary traction component 2 includes an upper traction roller 21, a lower traction roller 22, and a pressing cylinder 23 that drives the upper traction roller 21 to move up and down. The upper traction roller 21 and the lower traction roller 22 are arranged opposite each other. The pressing cylinder 23 is used to drive the upper traction roller 21 to move down to press the car wrap film between the upper traction roller 21 and the lower traction roller 22, so as to pull the car wrap film from front to back.

[0020] like Figure 1 , 2As shown, the cutting and winding device 20 includes a support frame 201 and a cutting mechanism 4, a swing roller mechanism 5, and a pressure roller mechanism 3 mounted on the support frame 201. The cutting mechanism 4 includes a swing arm 41 rotatably mounted on the support frame 201, a cutting assembly 42, and a smoothing strip 43 mounted on the swing arm 41. One end of the swing arm 41 is rotatably connected to the support frame 201, and the cutting assembly 42 and the smoothing strip 43 are mounted on the other end of the swing arm 41. The cutting mechanism 4 includes an upward swinging cutting position and a downward swinging waiting position. The cutting assembly 42 cuts the car wrap film on the winding device 30 at the cutting position.

[0021] like Figure 1 , 3 As shown in Figure 4, the winding device 30 includes a frame 71, a rotating frame 72 rotatably mounted on the frame 71, a pair of winding shafts 73 rotatably mounted on the rotating frame 72 about their own axis, and a winding drive mechanism 8 and a flipping drive mechanism 9 that are driveably connected to the rotating frame 72. The winding device 30 also includes a winding station 301 and a winding change station 302 arranged opposite to each other. The winding drive mechanism 8 includes a pair of servo motors 81, which are driveably connected to the pair of winding shafts 73 through the rotating frame 72, so as to drive the corresponding winding shafts 73 to rotate relative to the rotating frame 72 about their own axis.

[0022] The flipping drive mechanism 9 includes a flipping motor 91, a worm gear 92 that is driven by the flipping motor 91, and a worm wheel 93 that is coaxially arranged with the rotating frame 72. The worm wheel 93 meshes with the worm gear 92. The worm wheel 93 and the worm gear 92 transmit the power of the flipping motor 91 to the rotating frame 72, which drives the rotating frame 72 to flip relative to the frame 71 around a center line X1 that extends in the left-right direction. This allows a pair of take-up shafts 73 to alternately flip to the take-up station 301 for normal take-up. The take-up shafts 73 rotate to the change-up station 302 to unwind and replace with new take-up shafts 73.

[0023] like Figure 3 , 5 As shown, two clamping mechanisms 6 are mounted on the rotating frame 72. Each take-up shaft 73 is equipped with one clamping mechanism 6. Each clamping mechanism 6 includes a pair of clamping cylinders 61 arranged opposite each other and a pair of stop rods 62 corresponding to each pair of clamping cylinders 61. The pair of stop rods 62 are arranged in the axial direction of the corresponding take-up shaft 73. Each clamping cylinder 61 has a clamping position that engages with the end of the corresponding take-up shaft 73 and a releasing position that is separated from the corresponding take-up shaft 73. When the pair of clamping cylinders 61 is in the releasing position, at least a portion of each stop rod 62 protrudes from the inner side of the corresponding clamping cylinder 61. The air rod 611 of each clamping cylinder 61 is hollow, and each stop rod 62 passes through the hollow part of the air rod 611 of the corresponding clamping cylinder 61. The air rod 611 is configured to be movable relative to the stop rod 62 in the left-right direction.

[0024] When the air rod 611 of the clamping cylinder 61 moves from the clamping position to the releasing position, the stop rod 62 abuts against the end of the take-up shaft 73, preventing the take-up shaft 73 from being difficult to disengage from the clamping cylinder 61 as it moves along the axial direction with the clamping cylinder 61 when the clamping cylinder 61 retracts. This reduces the difficulty of disengaging the take-up shaft 73 from the corresponding clamping cylinder 61, saves time when changing rolls, and makes the take-up device easier to operate when changing to take-up shafts of different sizes, reducing the difficulty of changing shafts.

[0025] The distance between a pair of stop bars 62 in each clamping mechanism 6 is greater than the length of the take-up shaft 73, so that the take-up shaft 73 can be removed from the clamping mechanism 6 when the clamping cylinder 61 of the clamping mechanism 6 is in the released position.

[0026] like Figure 1 , 2 As shown, when the cutting mechanism 4 is in the cutting position, the cutting component 42 and the smoothing strip 43 are close to the take-up shaft 73 of the take-up station 301. The cutting component 42 is used to cut the car wrap film between the take-up station 301 and the roll-changing station 302. The smoothing strip 43 is used to smooth the beginning of the cut car wrap film on the take-up shaft 73 when the take-up shaft 73 of the take-up station 301 rotates, thereby improving the roll-up effect.

[0027] The cutting assembly 42 includes a rodless cylinder 421 mounted on the swing arm 41 and a cutter 422 mounted on the rodless cylinder 421. The rodless cylinder 421 is used to drive the cutter 422 to move in the left and right direction to cut the car wrap film, so as to meet the roll changing of the winding device 30.

[0028] The swing roller mechanism 5 includes a swing roller 51 oscillatingly mounted on the support frame 201 and a swing cylinder 52 that drives the swing roller 51 to swing back and forth. An angular displacement sensor (not shown in the figure) is installed at the swing roller 51. The angular displacement sensor is used to detect the real-time tension of the car wrap film at the swing roller 51 and transmit the detection result to a tension controller. The tension controller is connected to a pair of servo motors 81. The tension controller transmits the detection result to the corresponding servo motor 81, so that the servo motor 81 adjusts the speed of the corresponding take-up shaft 73 to ensure constant tension take-up.

[0029] The pressure roller mechanism 3 includes a pressure roller 31 mounted on a support frame 201 that moves in the front-to-back direction. The pressure roller 31 is arranged close to the take-up station 301. During the rotation of the take-up shaft 73 at the take-up station 301, the pressure roller 31 presses the car wrap film between itself and the take-up shaft 73 to squeeze out air bubbles in the car wrap film, ensuring the quality of the take-up of the car wrap film. The pressure roller 31 is configured to gradually move away from the take-up shaft 73 at the take-up station 301 as the thickness of the roll material on the take-up shaft 73 increases, so that the distance between them adapts to the increase in the thickness of the roll material. The swing roller 51 is located upstream of the pressure roller 31.
