[0017] This utility model embodiment provides a die-cutting machine film feeding device, such as... Figure 1-5 As shown, the die-cutting machine film feeding device includes: a die-cutting machine body 1; a support frame 2 and an extension frame 3 respectively installed on both sides of the die-cutting machine body 1; a plurality of support shafts respectively rotatably installed on the die-cutting machine body 1, the support frame 2 and the extension frame 3 for supporting the film material; an output roller 4 placed on the support frame 2 for outputting the film; and a winding roller 5 detachably installed on the extension frame 3 for winding the film. The winding roller 5 is used to wind up the film output by the output roller 4, which can contact the top of the rigid film located at the top of the support shaft, and drive the rigid film to move through the contact friction to achieve automatic loading and unloading.

[0018] In this embodiment, by setting the support frame 2 and the extension frame 3 on both sides of the die-cutting machine body 1 and configuring multiple support shafts, the purpose of stabilizing the film material is achieved, ensuring the flatness and stable transmission of the film material during processing. By setting the output roller 4 placed on the support frame 2, the stable output of the film is realized. By setting the take-up roller 5 detachably installed on the extension frame 3, the take-up roller 5 can take up the film output by the output roller 4, and the film can contact the top of the rigid film. The contact friction force drives the rigid film to move, which plays the role of automatic loading and unloading, avoiding machine downtime, making the processing process more continuous and efficient, and improving the overall processing efficiency of the die-cutting machine.

[0019] In a further preferred embodiment of the present invention, a connecting cylinder 11 is rotatably sleeved on the output roller 4, and a notch for accommodating the connecting cylinder 11 is provided on the support frame 2. A clamping plate 13 is fixed on the outer wall of the connecting cylinder 11, and a slot 12 for accommodating the clamping plate 13 is provided in the notch.

[0020] In this embodiment, by rotating the connecting cylinder 11 around the output roller 4 and providing a notch on the support frame 2 to accommodate the connecting cylinder 11, the connecting cylinder 11 can be stably placed on the support frame 2, which serves to initially position the output roller 4. By fixing the clamping plate 13 on the outer wall of the connecting cylinder 11 and providing a clamping slot 12 in the notch to accommodate the clamping plate 13, the connecting cylinder 11 can be more firmly fixed on the support frame 2, effectively preventing the output roller 4 from shaking or shifting during operation, making the output roller 4 more stable and reliable when outputting film, and ensuring the continuity and uniformity of film output.

[0021] In a further preferred embodiment of the present invention, a rotating shaft 9 is rotatably mounted on the extension frame 3, a connecting plate 8 is fixed on the rotating shaft 9, a clamping plate 7 is hinged on the connecting plate 8, an extension plate 6 extending into the clamping plate 7 is fixed on the take-up roller 5, and a fixing bolt penetrating the extension plate 6 is threaded on the clamping plate 7.

[0022] In this embodiment, by rotating and installing the shaft 9 on the extension frame 3 and fixing the connecting plate 8 on the shaft 9, the connecting plate 8 can rotate flexibly, which can flexibly adjust the angle to adapt to different installation requirements. By hinged clamping plate 7 on the connecting plate 8 and setting an extension plate 6 extending into the clamping plate 7 on the take-up roller 5, and cooperating with the fixing bolts threaded on the clamping plate 7 that penetrate the extension plate 6, the take-up roller 5 can be installed and disassembled quickly and stably. This not only enhances the stability of the installation of the take-up roller 5 and prevents it from loosening or falling off during operation, but also facilitates the quick replacement of the take-up roller 5.

[0023] In a further preferred embodiment of the present invention, the clamping plates 7 are arranged in groups and respectively located on both sides of the extension plate 6, and the extension frame 3 is equipped with a motor 10 for driving the rotating shaft 9 to rotate, and the output shaft of the motor 10 is connected to the rotating shaft 9 through a coupling.

[0024] In this embodiment, by grouping the clamping plates 7 and placing them on both sides of the extension plate 6, and using fixing bolts, the extension plate 6 is securely clamped, effectively preventing the take-up roller 5 from shaking or shifting during operation, thus improving the stability of the take-up operation. By installing a motor 10 (taking PMM2802 as an example) on the extension frame 3 and connecting the output shaft of the motor 10 to the rotating shaft 9 using a coupling, the motor 10 can directly drive the rotating shaft 9 to rotate, thereby driving the take-up roller 5 to automatically rotate and take up the film. This achieves automation of the take-up process, reduces manual intervention, improves take-up efficiency, and makes the take-up force uniform and controllable.

[0025] In a further preferred embodiment of the present invention, the connecting cylinder 11 is composed of an outer cylinder 15 fixed on the card plate 13 and an inner cylinder 16 rotatably installed inside the outer cylinder 15. The inner cylinder 16 is fixedly sleeved outside the output roller 4. Guide grooves are provided on the inner wall of the outer cylinder 15 and the outer wall of the inner cylinder 16. A ball bearing 17 for reducing rotational friction is provided between the two guide grooves.

[0026] In this embodiment, by setting the connecting cylinder 11 as a structure consisting of an outer cylinder 15 and an inner cylinder 16 rotatably installed therein, and the inner cylinder 16 is fixedly sleeved on the outside of the output roller 4, the output roller 4 can rotate flexibly with the inner cylinder 16 relative to the outer cylinder 15, which plays the role of stabilizing the support of the output roller 4 while ensuring its smooth rotation. By setting guide grooves on the inner wall of the outer cylinder 15 and the outer wall of the inner cylinder 16, and setting ball bearings 17 between the guide grooves, the rolling friction of the ball bearings 17 is used to replace the traditional sliding friction, which achieves the effect of significantly reducing rotational friction.

[0027] In a further preferred embodiment of the present invention, the die-cutting machine body 1 is provided with a discharge port 18, the bottom of the discharge port 18 and the top of the support shaft are located on the same horizontal line to assist in the continuous conveying of the rigid film, and a shock-absorbing pad for vibration reduction and noise reduction is installed in the recess.

[0028] In this embodiment, by setting a discharge port 18 on the die-cutting machine body 1 and positioning its bottom and the top of the support shaft at the same horizontal level, the purpose of assisting in the continuous conveying of rigid film is achieved. This ensures that the rigid film can move smoothly and steadily during the die-cutting process, reducing jamming or offset caused by height differences and improving processing accuracy. By installing shock-absorbing pads in the notch, the vibration and noise reduction effects are achieved, effectively reducing the vibration and noise during equipment operation. This not only improves the working environment but also reduces the impact of vibration on the stability of film material transmission.

[0029] In a further preferred embodiment of the present invention, a pressure shaft 14 that can contact the film and is used to adhere the film to the rigid film is rotatably mounted on both the support frame 2 and the extension frame 3. The pressure shaft 14 and the plurality of support shafts are all covered with a silicone soft sleeve for preventing damage to the film material.

[0030] In this embodiment, by rotating the pressure shaft 14 on the support frame 2 and the extension frame 3, the pressure shaft 14 can contact the film and adhere it to the rigid film, achieving the effect of automatic bonding between the film and the rigid film. This avoids the tediousness and errors of manual operation, improves the efficiency of loading and unloading and the bonding accuracy. At the same time, silicone soft sleeves are fitted on the outside of the pressure shaft 14 and multiple support shafts. The softness of silicone prevents the film material from being scratched or worn during the transmission process, effectively protecting the surface quality of the film and the rigid film.

[0031] In a further preferred embodiment of the present invention, the motor 10 is covered with a protective shell for protecting the motor 10, and the protective shell is provided with heat dissipation holes for assisting the motor 10 in dissipating heat. The support frame 2 and the extension frame 3 are both mounted on the die-cutting machine body 1 by electric telescopic rods to assist in adjusting the height of the soft film to adapt to hard films of different thicknesses.

[0032] In this embodiment, by covering the motor 10 with a protective shell, the motor 10 is protected from external dust, debris and other corrosive substances, thus extending the service life of the motor 10. The heat dissipation holes on the protective shell help dissipate heat from the motor 10, preventing the motor 10 from overheating and being damaged due to prolonged operation, and ensuring the stable operation of the motor 10. The support frame 2 and the extension frame 3 are installed on the die-cutting machine body 1 by an electric telescopic rod (taking the SXTL small electric push rod telescopic rod as an example), so that the height of the soft film can be flexibly adjusted according to the hard film of different thicknesses, which can adapt to various processing needs and improve the versatility and flexibility of this device.

[0033] In summary, compared with related technologies, this device stabilizes the rigid film by setting up a support frame 2, an extension frame 3, and multiple support shafts. It also ensures the smooth and stable transmission of the film material by using a soft film that adheres to the rigid film. By setting up a take-up roller 5 and an output roller 4 and their accessories, it can not only output the soft film to drive the rigid film to move for loading and unloading, but also directly transport the soft film material to be processed to achieve loading and unloading.
