[0034] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0035] like Figure 1 and Figure 2 As shown, this embodiment provides a hot stamping mechanism for a transfer film A, which includes a hot stamping roller 1, a driving roller 2, a moving assembly 3, a heating assembly 4, and a driving assembly 5. The heating assembly 4 is located in the circumferential direction of the hot stamping roller 1, and the heating assembly 4 extends along the axial direction of the hot stamping roller 1 to heat the hot stamping roller 1. The hot stamping roller 1 and the driving roller 2 are arranged relative to each other. The hot stamping roller 1 is used to hot stamp the transfer film A onto the substrate B driven by the driving roller 2. The output end of the driving assembly 5 is connected to the hot stamping roller 1 to drive the hot stamping roller 1 to rotate along its axis. The moving end 311 of the moving assembly 3 is connected to the hot stamping roller 1, the heating assembly 4, and the driving assembly 5 to simultaneously drive the hot stamping roller 1, the heating assembly 4, and the driving assembly 5 to move closer to or away from the driving roller 2. As shown Figure 2As shown, the moving assembly 3 includes moving units 31 located at both ends of the hot stamping roller 1 , and the two moving units 31 have the same structure and both include a moving end 311 .

[0036] Since the heating component 4 is located on the circumference of the hot stamping roller 1 and extends along the axial direction of the hot stamping roller 1 to heat the hot stamping roller 1, and since a driving component 5 is provided to independently drive the hot stamping roller 1 to rotate, the hot stamping roller 1 can rotate even when the driving roller 2 is not working, so that the heating component 4 can evenly heat the entire circumferential surface of the hot stamping roller 1, so that the hot stamping roller 1 is heated more evenly, and the rotation of the hot stamping roller 1 can prevent the circumferential surface of the hot stamping roller 1 from being damaged due to local heating, thereby extending the service life of the hot stamping roller 1, improving the pass rate of the transfer film A after hot stamping, and reducing the production cost of floor panels.

[0037] It should be noted that during the hot stamping process, the transfer film A and substrate B simultaneously enter between the hot stamping roller 1 and the drive roller 2, with the substrate B close to the drive roller 2 and the transfer film A close to the hot stamping roller 1. The hot stamping roller 1 is used to hot stamp the transfer film A onto the substrate B. In actual application, the relative positions of the hot stamping roller 1 and the drive roller 2 are set according to actual needs. In this embodiment, the hot stamping roller 1 and the drive roller 2 are arranged one above the other.

[0038] like Figure 2 and Figure 3 As shown, the heating assembly 4 includes two arc-shaped mounting frames 42 and multiple heating units 41. The two arc-shaped mounting frames 42 are respectively connected to the movable ends 311 of the two movable units 31, and the multiple heating units 41 are connected between the two arc-shaped mounting frames 42 so that the multiple heating units 41 are distributed in an arc shape on the circumference of the hot stamping roller 1.

[0039] The heating units 41 are arranged at equal intervals along the circumference of the hot stamping roller 1 and extend from the leading end to the trailing end of the hot stamping roller 1. In actual use, the heating units 41 can be oil-heated or electrically heated. In this embodiment, preferably, each heating unit 41 includes a lampshade 411 and a long strip lamp tube 412, which is disposed within the lampshade 411. Preferably, three heating units 41 are provided, each of which is provided with two long strip lamp tubes 412. To ensure heating efficiency, in this embodiment, the power of each long strip lamp tube 412 is 1.5 kW, that is, in this embodiment, the power of the entire heating assembly 4 is 9 kW, thereby increasing the heating speed of the hot stamping roller 1.

[0040] In order to ensure the overall strength of the heating assembly 4 , the heating assembly 4 further includes at least one reinforcing rod 43 , and both ends of the reinforcing rod 43 are respectively connected to the two arc-shaped mounting brackets 42 .

[0041] In order to make the mobile end of the mobile unit move more smoothly, the hot stamping mechanism of the transfer film A also includes two connecting frames 6. The two mobile units 31 and the two connecting frames are arranged in a one-to-one correspondence. The fixed end of the mobile unit 31 is connected to the connecting frame 6. An open slide groove 61 is opened on the connecting frame 6 in the vertical direction. The mobile end 311 of the mobile unit 31 is slidably connected to the open slide groove 61.

[0042] To prevent inconsistent rotational speeds between the drive roller 2 and the hot stamping roller 1, which in turn can lead to inconsistent transport speeds for the transfer film A and substrate B, and thus a low hot stamping yield, the transfer film hot stamping mechanism also includes a position sensor 8. This sensor is used to detect the operating position of the hot stamping roller 1. When the hot stamping roller 1 is in the operating position, the drive assembly 5 stops driving the hot stamping roller 1 to rotate. In this embodiment, the position sensor 8 is a proximity switch, mounted on any connecting bracket 6, and is used to detect whether the moving assembly 3 has driven the hot stamping roller 1 to a predetermined position, which is the hot stamping roller's operating position.

[0043] When the proximity switch touches the limit block on the moving end of the moving component 3, the driving component 5 is turned off and stops driving the hot stamping roller 1 to rotate. At this time, the rotation of the hot stamping roller 1 is driven by the driving roller 2, which saves the power consumption of the driving component 5 and avoids the problem of low reliability caused by inconsistent rotation speeds of the driving roller 2 and the hot stamping roller 1.

[0044] In order to make the incoming transfer film A flat and wrinkle-free, Figure 4 As shown, the hot stamping mechanism further includes a bending roller 7, which is rotatably connected to one side of the connecting frame to unfold the transfer film A entering between the hot stamping roller 1 and the driving roller 2. To achieve a better flattening effect, the angle between the transfer film A and the bending roller 7 is less than 15°.

[0045] like Figure 2 As shown, in this embodiment, the drive assembly 5 includes a drive motor 51, a driving gear 52, a driven gear 53, and a chain 54. The output end of the drive motor 51 is connected to the driving gear 52, and the drive motor 51 can drive the driving gear 52 to rotate along its own axis. The driven gear 53 is mounted on and fixed to the input end of the hot stamping roller 1. The chain 54 is mounted on the driving gear 52 and the driven gear 53 and meshes with the driving gear 52 and the driven gear 53. The drive motor 51 drives the driving gear 52 to rotate, and the driving gear 52 drives the driven gear 53 to rotate via the chain 54 thereon, thereby rotating the hot stamping roller 1.
