[0002] The longitudinal foil feeding telescopic device of the die-cutting and hot stamping machine is a key component installed on the die-cutting and hot stamping machine. It is mainly used for longitudinal conveying and tension control of hot stamping foil in the hot stamping process. Through the telescopic structure, it automatically adjusts the foil conveying length and speed to ensure that the hot stamping foil maintains constant tension during longitudinal transmission, avoiding problems such as slackness and stretching deformation, thereby improving hot stamping accuracy and product quality, and ensuring the stability and efficiency of the die-cutting and hot stamping process.

Traditional foil feeding devices typically employ complex combinations of parts for telescopic adjustment, resulting in cumbersome structures, high processing costs, and inconvenient maintenance. Furthermore, frequent disassembly of components is required when changing electroplated aluminum rolls, impacting production efficiency. Therefore, there is an urgent need for a longitudinal foil feeding telescopic device that is simple in structure and easy to operate. Utility Model Content

[0024] Please see Figure 1-3This utility model provides the following technical solution: a longitudinal foil feeding telescopic device for a die-cutting and hot stamping machine, comprising a foil feeding frame 1 and a foil feeding rod assembly 6. The foil feeding frame 1 has a guide rail at its rear end, on which a guide roller is rotatably connected to guide the conveying path of the electroplated aluminum foil and maintain uniform tension. The foil feeding rod assembly 6 is longitudinally slidably connected to the foil feeding frame 1 via a first guide rail slider 7 and a second guide rail slider 8. The foil feeding rod assembly 6 includes a transverse support rod and a longitudinal support leg. The sliders of the first guide rail slider 7 and the second guide rail slider 8 are fixed longitudinally. At the bottom of the support leg, the horizontal support rod has a through hole for the foil-feeding rod 9 to pass through, facilitating the installation of the support rail slider and the foil-feeding rod. The guide rail lengths of the first guide rail slider 7 and the second guide rail slider 8 are greater than the maximum extension stroke of the foil-feeding rod assembly 6, ensuring that the foil-feeding rod assembly 6 does not detach from the guide rail when sliding longitudinally. One end of the foil-feeding rod 9 is provided with a limiting structure, and the foil-feeding rod assembly 6 is provided with a corresponding limiting mating part. The locking button 2 is linked with the bracket 3 to release the limiting. The first guide rail slider 7 and the second guide rail slider 8 respectively include a guide rail and a slider, and the guide rail is fixed to the foil-feeding machine. Frame 1, with sliders fixed to foil-feeding rod assembly 6, has two sets of guide rail sliders symmetrically distributed along the longitudinal axis of foil-feeding rod assembly 6 to enhance sliding stability. Foil-feeding rod 9 is detachably mounted on foil-feeding rod assembly 6 via locking button 2 and bracket 3. Locking button 2 includes a knob screw passing through foil-feeding rod assembly 6 and a positioning hole at the end of foil-feeding rod 9. Bracket 3 is movably connected to foil-feeding rod assembly 6. Foil-feeding rod 9 can be removed by loosening the knob screw and moving bracket 3. Bracket 3 is elastically connected to foil-feeding rod assembly 6 via a spring. When the locking button... 2. When tightened, the spring compression causes the bracket 3 to press against the end of the foil-feeding rod 9, forming an anti-loosening locking structure. The front end of the foil-feeding frame 1 is provided with a stop block 5, and the front end of the foil-feeding rod assembly 6 is provided with a positioning block 4 that cooperates with the stop block 5.
