[0026] Reference Figures 1 to 5 A protective film rapid winding device is shown, comprising a base 1 and a winding drum 10. The winding drum 10 is detachably mounted on the base 1. The base 1 is used to support the winding component 2 and the splitting component 4. One end of the protective film is attached to the surface of the winding drum 10, and then the winding drum 10 is rotated to wrap the protective film around the outside of the winding drum 10. It also includes a winding component 2 and a cutting component 4, the cutting component 4 is used to cut the protective film, the winding component 2 includes a support seat 20, a rotating shaft 21, a pair of blocks 22, a first spring 23, a first baffle 24, a second baffle 25 and a second spring 26, the bottom of the support seat 20 is fixedly connected to the top of the base 1, one end of the rotating shaft 21 is rotatably connected to the support seat 20, the outer periphery of the rotating shaft 21 is slidably connected to the winding drum 10, and a pair of grooves 100 are opened on the inner wall of the winding drum 10, the grooves 100 are slidably connected to the protrusions on the rotating shaft 21, the grooves 100 on the winding drum 10 are aligned with the protrusions on the rotating shaft 21, and the winding drum 10 is moved to insert the rotating shaft 21 into the winding drum 10, and then the rotating shaft 21 is rotated, which can drive the winding drum 10 to rotate. A T-shaped slot 210 is provided at the other end of the rotating shaft 21, one end of the block 22 is slidably connected to the T-shaped slot 210, one end of the first spring 23 is fixedly connected to the top block 22, the other end of the first spring 23 is fixedly connected to the bottom block 22, the first baffle 24 is slidably connected to the periphery of the rotating shaft 21, the second spring 26 is sleeved on the periphery of the rotating shaft 21, one end of the second spring 26 is fixedly connected to the first baffle 24, the other end of the second spring 26 is fixedly connected to the second baffle 25, and a through slot 250 is provided at one end of the second baffle 25, the block 22 passes through the slot 250 and is engaged therewith. After the winding drum 10 is sleeved on the outer periphery of the rotating shaft 21, one end of it is fitted with the supporting seat 20, the first baffle 24 is aligned with the rotating shaft 21 and the second baffle 25 is moved to make the first baffle 24 fit with the other end of the winding drum 10. As the second baffle 25 moves, the second spring 26 gradually contracts. When the second baffle 25 contacts the block 22, as the movement continues, the first spring 23 contracts, and the two blocks 22 slide along the T-slot 210 and approach each other. When one end of the block 22 passes through the empty slot 250, the first spring 23 rebounds, pushing the two blocks 22 to be stuck at both ends of the empty slot 250, fixing the second baffle 25 on the rotating shaft 21. At this time, the first baffle 24 is pushed against the winding drum 10 by the rebound force of the second spring 26 to prevent the winding drum 10 from sliding on the rotating shaft 21, and the contraction and rebound characteristics of the second spring 26 can fix winding drums 10 of different lengths, and the scope of application is wide.

[0027] like Figures 1 to 4As shown, the winding assembly 2 also includes a pair of support rods 3, a pair of pressure rollers 30 and a pair of third springs 31. The two support rods 3 are symmetrically distributed at both ends of the base 1. The bottom of the support rods 3 is fixedly connected to the top of the base 1. The bottom pressure roller 30 is fixedly installed between the two support rods 3. The top pressure roller 30 can be installed vertically and slidably between the two support rods 3. The third spring 31 is sleeved on the outer periphery of the support rods. The third spring 31 is used to provide a downward pulling force to the top pressure roller 30. One end of the protective film is first passed through the two pressure rollers 30 and then fixed to the winding drum 10. Then, when winding, the top pressure roller 30 presses down the protective film and cooperates with the bottom pressure roller 30 to clamp it. The protective film can be fixed and flattened. At the same time, due to the friction between the protective film and the pressure roller 30, the pressure roller 30 rotates with the movement of the protective film when winding, which can keep the protective film tight and prevent wrinkles when winding.

[0028] like Figures 1 to 4 As shown, the two ends of the pressure roller 30 are rotatably connected with fixed blocks 32, the bottom fixed block 32 is fixedly connected to the periphery of the support rod 3, the top fixed block 32 is slidably connected to the periphery of the support rod 3, one end of the third spring 31 is fixedly connected to the bottom of the top fixed block 32, and the other end of the third spring 31 is fixedly connected to the top of the bottom fixed block 32. First, pull the top pressure roller 30 upward to make the top fixed block 32 slide along the support rod 3, and the third spring 31 is stretched. At this time, the two pressure rollers 30 are separated, and after the protective film passes through them, the top pressure roller 30 is released to make it fall, and at the same time, the third spring 31 rebounds, pulling the top fixed block 32 down, thereby driving the top pressure roller 30 to press the protective film downward.

[0029] like Figures 1 to 4 As shown, the winding assembly 2 also includes a pair of rotating disks 33, one of which is coaxially connected to the periphery of one end of the bottom pressure roller 30, and the other rotating disk 33 is fixedly connected to the bottom fixed block 32, and the opposite ends of the two rotating disks 33 are fixedly connected to a plurality of friction strips 34, and the friction strips 34 on the two rotating disks 33 fit each other. When the pressure roller 30 rotates, it will drive one of the rotating disks 33 to rotate, and at this time, the two rotating disks 33 rotate relative to each other, and the friction strips 34 on the two rotating disks 33 rub against each other to generate resistance, so that the rotation of the pressure roller 30 is hindered, thereby increasing the pulling force received by the protective film, and the protective film can be further kept tight.

[0030] like Figures 1 to 4As shown, the cutting assembly 4 includes a support frame 40, a circular cutting knife 41, a circular shaft 42, a handle 43 and a sliding frame 44. The bottom of the support frame 40 is fixedly connected to the top of the base 1, one side of the bottom of the sliding frame 44 passes through the support frame 40 and is slidably connected thereto, the handle 43 is fixedly connected to one side of the circular shaft 42, the circular shaft 42 passes through the top of the sliding frame 44 and is fixedly connected thereto, the other side of the circular shaft 42 is rotatably connected to the circular cutting knife 41, and the bottom of the circular cutting knife 41 and the top of the support frame 40 are in conflict with each other. After the winding is completed, the protective film is placed on the top of the support frame 40, and then the handle 43 is moved to make the sliding frame 44 slide along the support frame 40, and the circular cutting knife 41 rolls on the top of the support frame 40 while following the movement of the sliding frame 44, so that the protective film can be cut.

[0031] like Figure 1 to Figure 2 As shown, the winding assembly 2 also includes a motor 27, one end of which is fixedly connected to the support seat 20, and the output shaft of the motor 27 passes through the support seat 20 and is coaxially connected to the rotating shaft 21. When the motor 27 is powered on, its output shaft can drive the rotating shaft 21 to rotate for winding.

[0032] It should be noted that the above specific implementations are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention. However, as long as these changes do not deviate from the spirit of the present invention, they should be within the scope of protection of the present invention.
