Description

Technical Field

[0001] The utility model relates to the technical field of thermal transfer, in particular to a thermal transfer film flattening device. Background Art

[0002] During the production process of thermal transfer film, the film material needs to be wound before it can enter the market for other manufacturers to use for thermal transfer decoration. However, if the film material is not flat before winding, it may lead to poor winding effect, wrinkles or uneven surface problems, which in turn affects the appearance and quality of the finished product. In addition, the unevenness of the film material will increase the difficulty of subsequent processing, limit the thermal transfer effect, and even affect the overall added value of the product. Existing leveling devices mostly use a pressing block to directly stretch the film material for leveling. Although it can improve the flatness to a certain extent, this stretching method is usually prone to causing slight damage to the surface of the film material, and even affects the gloss and toughness of the film material, reducing the overall quality and market competitiveness of the product.

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0024] Example: See Figure 1 - Figure 4 In this embodiment, a heat transfer film flattening device is provided, which is specifically used to flatten the heat transfer film before it is rolled up to ensure the aesthetics of the rolling effect and the quality of the finished product. The device specifically includes: an operating platform 11, a support module 12, and a flattening module 13.

[0025] The supporting module 12 includes two sets of baffles 14 fixed on the operating machine 11 along the conveying direction of the thermal transfer film, and a plurality of rollers 15 are rotatably arranged between the two sets of baffles 14;

[0026] See also Figure 4 The leveling module 13 includes a transmission belt 16 and pulleys 17 arranged at both ends of the transmission belt 16. A driving motor 18 is provided on each pulley 17 to drive the pulley 17 to rotate. A plurality of scrapers 19 are provided on the outside of the transmission belt 16.

[0027] Specifically, in this embodiment, the thermal transfer film is located above the roller 15 during transportation, and the bottom portion contacts the surface of the roller 15 to generate rolling friction. The roller 15 is in contact with the lower surface of the thermal transfer film during rotation, and the uniform rolling of the roller 15 reduces wrinkles and deviations of the film during transportation. The leveling module 13 drives the scraper 19 through the transmission belt 16 to perform a smooth flattening process on the upper surface of the thermal transfer film. The scraper 19 moves under the drive of the transmission belt 16, so that the entire surface of the film is uniformly leveled, thereby effectively eliminating wrinkles and bubbles on the surface of the film. The device achieves efficient leveling of the thermal transfer film through the cooperation of the support module 12 and the leveling module 13, meeting the requirements of a flat and beautiful film before winding.

[0028] In this embodiment, in order to improve the flexibility and adaptability of the leveling process, the thermal transfer film leveling device further includes a moving unit 21. The moving unit 21 includes a support column 22 disposed above the operating platform 11, and a lifting platform 23 is mounted on the support column 22. The lifting platform 23 is used to support and adjust the height position of the leveling module 13. Specifically, the leveling module 13 is symmetrically arranged in two groups. The leveling module 13 is connected to the bottom of the lifting platform 23 by rotation and is driven to rotate by a servo 24. The servo 24 adjusts the flattening range of the leveling assembly and the flattening direction of the scraper 19 relative to the thermal transfer film, so that the scraper 19 presses from the middle of the thermal transfer film to both sides, thereby better eliminating wrinkles or bubbles in the middle area, thereby ensuring the uniformity of the leveling effect.

[0029] Among them, the lifting platform 23 includes four groups of lifting rods 31 that are slidably connected and adapted to the support columns 22. Guide bars 32 are provided at both ends of the lifting rods 31. Guide grooves 33 that are slidably adapted to the guide bars 32 are provided on the support columns 22. A support plate 34 is fixed above the support column 22. A driving cylinder 35 that drives the lifting rods 31 to move up and down is installed and fixed on the support plate 34. Support rods 36 are connected and fixed between the lifting rods 31. The linear module 41 is fixed between the support rods 36 and the lifting rods 31. The piston rod 37 of the driving cylinder 35 is fixed on the lifting rod 31. The driving cylinder 35 drives the lifting rod 31 to move up and down along the guide groove 33 of the support column 22 through the extension and retraction of the piston rod 37 to realize the height adjustment of the linear module 41.

[0030] In addition, the moving unit 21 further includes a linear module 41 for driving the servo 24 of the leveling module 13 to perform precise linear movement in the lateral direction. Figure 3The linear module 41 consists of a ball screw 42 and a slide 43. The ball screw 42 is driven by a motor 44, which allows the slide 43 to slide along a track 45. The servo 24, mounted on the slide 43, drives the flattening module 13 horizontally on the operating platform 11, enabling precise flattening of different areas of the thermal transfer film. The linear module 41 and the servo 24 combine to drive the horizontal movement and rotation of the flattening assembly, allowing for more flexible adjustment of the flattening coverage (horizontal width) to meet the flattening requirements of thermal transfer films of varying widths.

[0031] See also Figure 5 In this embodiment, the scraper 19 includes a connecting seat 51 and a scraper blade 52. The connecting seat 51 is fixed to the outside of the transmission belt 16, so that the scraper 19 can move synchronously with the transmission belt 16. The scraper blade 52 is slidably mounted on the connecting seat 51, and the scraper blade 52 has a certain adjustment gap relative to the connecting seat 51. In order to accurately control the pressure applied by the scraper blade 52, pressure adjustment components 53 are designed on both sides so that the pressure of the scraper blade 52 when in contact with the film material can be adjusted according to actual needs. Specifically, the pressure adjustment component 53 includes a fixing stud 54 fixed on the connecting seat 51 and a spring 55 mounted on the fixing stud 54. A connecting flap 56 is provided on each side of the scraper 52, and the spring 55 is located between the connecting seat 51 and the connecting flap 56 to provide pressure. A through hole is provided on the connecting flap 56, and the fixing stud 54 passes through the through hole and is threadedly connected to an adjusting nut 57 at the end. By rotating the adjusting nut 57, the spring 55 can be compressed or relaxed, thereby changing the pressure of the spring 55, and then adjusting the pressure applied by the scraper 52 to the thermal transfer film, so that the scraper 52 can fit closely to the surface of the film without damaging the surface of the film due to excessive pressure.

[0032] In this embodiment, the rollers 15 are arranged at equal intervals to provide continuous and uniform support for the thermal transfer film. Each group of rollers 15 includes several groups of coaxially arranged short rollers 61. Each group of short rollers 61 is rotatably mounted on the operating machine 11 via an axle seat 62. Each group of short rollers 61 can rotate independently and adapt to the conveying speed of the film material. At the same time, the short rollers 61 and axle seats 62 between adjacent rollers 15 are arranged alternately, that is, the position of the short rollers 61 of one group of rollers 15 corresponds to the position of the axle seat 62 of the adjacent rollers 15. Compared with the roller 15 composed of a single short roller 61, due to its segmented support design, the overall bending rigidity is enhanced, and it is not easy to bend or deform due to a longer span. It is particularly suitable for long-term operations or the processing of larger width films. In addition, when one of the short rollers 61 is worn or fails, the corresponding component can be replaced separately without replacing the entire roller 15 structure, reducing maintenance costs.

[0033] In this embodiment, the operating platform 11 is equipped with a movable wheel assembly 63 at its base, facilitating flexible movement within the work area to accommodate the needs of various production lines or operating environments, thereby enhancing the ease of use of the equipment. Furthermore, the movable wheel assembly 63 may be equipped with a locking mechanism. Once the leveling device is moved to the desired position, the locking mechanism can be used to secure the platform, ensuring stability during operation.
