Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water transfer films, in particular to a film feeding mechanism for producing water transfer films. Background Art
[0002] The water transfer film is formed by printing patterns on a low-temperature water-soluble PVA (polyvinyl alcohol) film as a substrate. Generally, the film is a whole roll, and the free end of the film is pulled out to the equipment for printing patterns, and the film is fed by the traction of the equipment and the rotation of the whole roll of film. However, it is well known that different products on the market require water transfer films of different sizes. Therefore, when making water transfer films, a variety of films of different sizes are also required. Generally, whole rolls of films of different sizes require corresponding feeding mechanisms of different sizes to realize the feeding of rolled films. In this way, it is necessary to manufacture multiple feeding mechanisms of different sizes, resulting in increased production costs; if a fixed-size feeding mechanism is used to hold rolled films of different widths and diameters, as the film is continuously output, the diameter of the roll gradually decreases, causing the whole roll of film to fall, and the rolled film with a smaller width will move back and forth along the length direction during the feeding process, causing the output film to be skewed or creased, thereby affecting the quality of the printed water transfer film.

[0024] Example
[0025] Please refer to Figure 1 The utility model provides a film feeding mechanism for producing water transfer films, including an H-shaped bracket 10. The bracket 10 also includes a corner pad 40 installed at the bottom. The corner pad 40 has an anti-slip effect on one hand, and can adjust the height to adapt to the uneven ground on the other hand.
[0026] Please refer to Figure 1-4The bracket 10 is provided with a main roller 20 and an auxiliary roller 30. The auxiliary roller 30 is installed on both sides above the main roller 20. The main roller 20 and the auxiliary roller 30 form a groove for supporting the rolled film. The auxiliary roller 30 is installed at both ends of the bracket 10 through bearings. A driving motor 201 and a gear assembly 202 are installed at one end of the bracket 10 along the length direction. The driving motor 201 is connected to the gear assembly 202. The gear assembly 202 is connected to the main roller 20. The driving motor 201 drives the main roller 20 to rotate through the gear assembly 202. The rolled film is placed in the groove formed by the main roller 20 and the auxiliary roller 30. The main roller 20 drives the rolled film to rotate to realize the input of power.
[0027] Please refer to Figure 1-4 The two ends of the auxiliary roller 30 are provided with an inclination adjustment mechanism 31, and the inclination adjustment mechanism 31 is used to adjust the two auxiliary rollers 30 to be close to or away from the main roller 20. Specifically, the inclination adjustment mechanism 31 includes support plates 314 at both ends of the bracket 10, and the support plates 314 are provided with two inclined U-shaped notches 311. A slider 312 is slidably installed in the U-shaped notch 311, and the slider 312 is connected to the auxiliary roller 30. A cross bar 315 is installed at the opening of the U-shaped notch 311, and an adjustment bolt 313 is arranged perpendicular to the cross bar 315. The head of the joint bolt 313 extends into the U-shaped notch 311 and is connected to the slider 312. The tail of the adjusting bolt 313 is installed on the cross bar 315 through a nut. Specifically, by tightening or loosening the nut at the same time, the adjusting bolt 313 drives the slider 312 to move along the U-shaped notch 311, driving the auxiliary roller 30 to approach or leave the main roller 20. When placing roll films of different diameters, the auxiliary roller 30 is adjusted to support the roll film, thereby solving the technical problem that the entire roll of film is easy to fall off due to the inability to adjust according to the diameter of the roll film.
[0028] Please refer to Figure 1-4Two limit plates 103 are slidably mounted on the bracket 10 , and the limit plates 103 are arranged above the auxiliary roller 30 . The two limit plates 103 approach or move away from each other along the bracket 10 . Specifically, the bracket 10 is slidably installed with a sleeve 101 on both sides along the length direction, the sleeve 101 can move along the bottom of the bracket 10, a vertically upward fixing rod 102 is installed on the side of the sleeve 101, the sleeve 101 drives the movement of the fixing rod 102, and a lower positioning bolt 105 is installed at the bottom of the sleeve 101. When the sleeve 101 moves into place, the positioning bolt is locked so that the sleeve 101 is fixed to the bottom of the bracket 10, and an upper positioning bolt 104 is installed on the upper end of the fixing rod 102. The limit plate 103 is installed on the fixing rod 102 through the upper positioning bolt 104, and the limit plate 103 is installed between the two fixing rods 102 through the upper positioning bolt 104, and as the fixing rod 102 moves, the distance between the two limit plates 103 is adjusted, so that the rolled film placed between the two limit plates 103 will not move during the output process. Furthermore, the limiting plate 103 is in an inverted convex shape, which is more suitable for the shape of the main roller 20 and the two auxiliary rollers 30, which is concave in the middle and convex on both sides, to limit the movement of the rolled film.
