Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] The present utility model provides a winding device for facilitating air flow film rewinding as Figures 1 to 5 shown, which includes a base 1. A first upright post 2 is fixedly arranged at one end of the base 1, and a second upright post 3 is slidably arranged at the other end of the base 1. Rotating shafts 15 are rotatably connected to the tops of the first upright post 2 and the second upright post 3, and positioning sleeves 16 are fixedly connected to one ends of the two rotating shafts 15 close to each other.

[0026] A chute 18 is opened on the upper surface of the base 1, and a slider 19 is slidably arranged inside the chute 18. The second upright post 3 is fixedly connected to the slider 19. The second upright post 3 moves on the base 1 through the slider 19 and the chute 18, and both the chute 18 and the slider 19 are in a T shape to improve the sliding stability. The second upright post 3 drives the rotating shaft 15 and the positioning sleeve 16 at its top position to move, facilitating the installation and positioning of the winding drum between the two positioning sleeves 16.

[0027] To achieve the adjustment and fixation of the position of the second column 3, a support plate 20 is fixedly connected to the upper surface of the base 1. The support plate 20 is located on the side of the second column 3 facing away from the first column 2. A threaded rod 21 is threadedly connected to the support plate 20. The threaded rod 21 is rotatably connected to the second column 3. A rotating block is fixedly connected to the end of the threaded rod 21 away from the second column 3. By rotating the rotating block to rotate the threaded rod 21, the second column 3 is driven to move, and the distance between the first column 2 and the second column 3 is adjusted. Moreover, the friction coefficient between the threaded rod 21 and the support plate 20 is appropriate, and the situation of random rotation will not occur.

[0028] A motor 17 is fixedly connected to the surface of the first column 2 facing away from the second column 3. A corresponding positioning sleeve 16 is fixedly connected to the drive shaft of the motor 17. The motor 17 drives the corresponding rotating shaft 15 and positioning sleeve 16 to rotate.

[0029] Specifically, one end of the winding drum is inserted into the positioning sleeve 16 at the top of the first column 2. Then, the threaded rod 21 is rotated through the rotating block, driving the second column 3 to move towards the first column 2, so that the positioning sleeve 16 at the top of the second column 3 is sleeved on the other end of the winding drum, completing the positioning of the winding drum. Then, the motor 17 can drive the rotating shaft 15 and positioning sleeve 16 at the top of the first column 2 to rotate, and with the cooperation of the rotating shaft 15 and positioning sleeve 16 at the top of the second column 3, the winding drum rotates to wind the air flow film; when the air flow film winding is completed, the threaded rod 21 is rotated in the reverse direction through the rotating block, driving the second column 3 to move away from the first column 2, releasing the positioning of the winding drum, which is convenient for removing the winding drum.

[0030] To prevent the air flow film from wrinkling during the winding process and improve the winding efficiency, a square tube 4 is fixedly connected to the upper surface of the base 1. A support column 5 is slidably arranged inside the square tube 4. The support column 5 penetrates through the upper surface of the square tube 4. The top of the support column 5 is fixedly connected to a cross plate 6. The support column 5 and the cross plate 6 are distributed in a T shape. An arc bar 7 is fixedly connected to the cross plate 6. The upper surface of the arc bar 7 is a concave surface. Both ends of the arc bar 7 are rotatably connected to a rotating rod 8. A roller 9 is fixedly connected to the rotating rod 8, and the rollers 9 are distributed along the axial length direction of the winding drum. A spring 12 is fixedly connected to the bottom end of the support column 5. A sliding plate 10 is slidably arranged inside the square tube 4. The bottom end of the spring 12 is fixedly connected to the sliding plate 10.

[0031] During the winding process, the two air flow films are respectively abutted against both sides of the bottom of the air flow film. As the winding drum continues to wind, the roller 9 squeezes the support column 5 through the arc bar 7 and the cross plate 6 to slide downward inside the square tube 4, and at the same time squeezes the spring 12 to contract. The reset elastic force of the spring 12 makes the roller 9 squeeze and fit on the air flow film, so that the air flow film is wound in a taut state, improving the winding efficiency.

[0032] Considering that when the air flow film is completely wound on the reel, the entire reel becomes heavier. When replacing the reel, it is impossible to quickly remove the wound reel from the winding device. To improve the efficiency of reel replacement, an electromagnet 14 is fixedly connected to the upper surface of the slide plate 10, and a magnetic block 13 is fixedly connected to the bottom end of the support column 5. The electromagnet 14 cooperates with the magnetic block 13.

[0033] Specifically, after the winding is completed, the electromagnet 14 is activated, and the magnetic properties of the mutually approaching surfaces of the electromagnet 14 and the magnetic block 13 are controlled to be the same. Under the action of the repulsive force, the position of the support column 5 is fixed, thereby fixing the position of the roller 9. The two rollers 9 cooperate to support the wound reel, so that the reel will not tip over or the like, facilitating the quick removal of the wound air flow film, and thus quickly replacing the reel.

[0034] At the same time, by adjusting the repulsive force between the electromagnet 14 and the magnetic block 13, the squeezing force of the roller 9 on the air flow film can be controlled, thereby controlling the tightness of the winding of the air flow film. When a greater tightness is required, the repulsive force between the electromagnet 14 and the magnetic block 13 can be increased.

[0035] And during the winding process, the repulsive force between the electromagnet 14 and the magnetic block 13 is gradually reduced adaptively to ensure that the support column 5 can slide downward.

[0036] In addition, the repulsive force between the electromagnet 14 and the magnetic block 13 is used in cooperation with the spring 12 to improve the flexibility of use and can be adjusted according to the specific usage situation.

[0037] By setting structures such as the roller 9, the electromagnet 14, and the magnetic block 13, after the winding is completed, the position of the support column 5 is fixed, facilitating the quick removal of the wound air flow film, and thus quickly replacing the reel; at the same time, by adjusting the repulsive force between the electromagnet 14 and the magnetic block 13, the squeezing force of the roller 9 on the air flow film can be controlled, thereby controlling the tightness of the winding of the air flow film.

[0038] To achieve automatic control of the repulsive force between the electromagnet 14 and the magnetic block 13, a pressure sensor 11 is fixedly connected to the lower surface of the slide plate 10. The pressure sensor 11 abuts against the bottom of the square tube 4. The roller 9 squeezes the support column 5 to slide downward inside the square tube 4 through the arc strip 7 and the cross plate 6, and at the same time squeezes the spring 12 to contract. The spring 12 causes the slide plate 10 to slide downward and squeeze the pressure sensor 11, thereby monitoring the tightness of the winding of the air flow film through the pressure sensor 11. Specifically, a controller can be set to be connected between the electromagnet 14 and the pressure sensor 11. When the pressure sensor 11 detects that the squeezing force exceeds the set threshold, this information is transmitted to the controller, and the controller adjusts the electromagnet 14. The controller and its control principle are common existing technologies and will not be elaborated here.
