[0003] Existing film printers often experience problems such as film shifting and wrinkling during the film output process, leading to decreased print quality and even film damage. Furthermore, existing film output mechanisms are poorly adaptable to different film sizes, failing to meet diverse printing needs. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides a film output mechanism for a film printer, including an output channel, a guide assembly, and a specification adjustment assembly.

[0005] The guiding assembly is installed in the film output channel. The guiding assembly includes multiple evenly distributed guide rollers. The front surface of the film output channel has a film output cavity. Guide grooves are provided on both sides of the film output cavity. A controller is fixedly connected to the side surface of the film output channel. A drive motor is fixedly connected to the side surface of the film output channel. A rotating shaft is fixedly connected to the output end of the drive motor. The side surface of the rotating shaft is fixedly connected to the guide rollers. The specification adjustment assembly includes an electric telescopic rod fixedly connected to the inner wall of the guide groove and an adjustment plate fixedly connected to the output end of the electric telescopic rod.

[0006] Through the above technical solution, the guide roller and guide groove cooperate to prevent the film from shifting during film transport and improve the film output accuracy. The electric telescopic rod drives the adjustment plate to move, thereby adjusting the distance between the two adjustment plates, so that the device can adapt to printing films of different widths and improve the practicality of the device. A single drive motor drives multiple guide rollers to rotate synchronously through a rotating shaft and a synchronous belt, which simplifies the transmission structure and reduces costs.

[0007] The present invention is further configured such that the film output channel is elongated, and the side surface of the guide roller is provided with a rubber anti-slip layer.

[0008] Through the above technical solution, the long strip-shaped film output channel provides a stable film transport path, reduces bending losses, and the rubber anti-slip layer increases the friction between the guide roller and the film, avoiding wrinkles or paper jams caused by slippage during transport.

[0009] The present invention is further configured such that a fixing plate is fixedly connected to the side surface of the film output channel, an mounting plate is movably connected to the lower surface of the fixing plate, a film printer body is fixedly connected to the side surface of the mounting plate, and a printing cavity is provided on the front surface of the film printer body.

[0010] The above technical solutions facilitate the disassembly and replacement of the film output channel, making maintenance and upgrades easier. The connection between the film output cavity and the printing cavity ensures a seamless transition of the film from printing to output, reducing the risk of misalignment.

[0011] The present invention is further configured such that a guide plate is provided on the upper surface of the film printer body, a film inlet is provided on the upper surface of the film printer body, and the film outlet cavity is connected to the printing cavity.

[0012] The present invention is further configured such that a bolt is fixedly connected to the upper surface of the mounting plate, a nut is threadedly connected to the side surface of the bolt, the bolt penetrates the fixing plate, and the upper surface of the fixing plate contacts the nut.

[0013] The above technical solution allows the film output channel to be installed onto the film printer body using bolts and nuts.

[0014] The present invention is further configured such that a groove is provided on the side surface of the rotating shaft, a timing belt is provided on the side surface of the rotating shaft, and a locking block is provided on the timing belt, the locking block being located within the groove.

[0015] Through the above technical solution, the meshing transmission between the card block and the groove avoids slippage, ensures that multiple guide rollers rotate synchronously, and prevents the film from being stretched or wrinkled due to speed differences.

[0016] The present invention is further configured such that the number of the specification adjustment components is two and they are arranged symmetrically, a vertical plate is fixedly connected to the upper surface of the film output cavity, and the side surface of the rotating shaft is rotatably connected to the vertical plate.

[0017] The above technical solutions reduce shaft wobbling, lower noise, and extend service life by using vertical plates and bearings.

[0018] The present invention is further configured such that the rotating shaft is fixedly connected to the film output channel via a bearing.

[0019] The beneficial effects of this utility model are as follows:

[0020] The guide rollers accurately guide the film, preventing it from shifting. Combined with the electric telescopic rod and adjustment plate of the specification adjustment component, the device can adapt to different film specifications, improving its versatility. Furthermore, the controller can adjust the speed of the drive motor driven by the guide rollers, allowing the device to flexibly adjust the film output speed according to actual needs.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] like Figures 1-5 As shown, the film output mechanism of a film printer in this embodiment includes an output channel 8, a guide assembly, and a specification adjustment assembly.

[0029] The guide assembly is installed in the film output channel 8. The guide assembly includes multiple evenly distributed guide rollers 15. The film output channel 8 is elongated. The side surface of the guide rollers 15 is provided with a rubber anti-slip layer. The guide rollers 15 cooperate with the guide groove 101 to prevent the film from deviating during film transport and improve the film output accuracy. The elongated film output channel 8 provides a stable film transport path and reduces bending loss. The rubber anti-slip layer increases the friction between the guide rollers 15 and the film, avoiding wrinkles or paper jams caused by slippage during transport.

[0030] The front surface of the film output channel 8 is provided with a film output cavity 10. Guide grooves 101 are provided on both sides of the film output cavity 10. A controller 11 is fixedly connected to the side surface of the film output channel 8. The controller 11, the drive motor 12 and the electric telescopic rod 17 are all electrically connected to an external motor. The drive motor 12 and the electric telescopic rod 17 are all electrically connected to the controller 11. This is prior art and is known to those skilled in the art.

[0031] A drive motor 12 is fixedly connected to the side surface of the film output channel 8. A rotating shaft 13 is fixedly connected to the output end of the drive motor 12. The side surface of the rotating shaft 13 is fixedly connected to the guide roller 15. A groove 14 is provided on the side surface of the rotating shaft 13. A synchronous belt 16 is provided on the side surface of the rotating shaft 13. A locking block is provided on the synchronous belt 16. The locking block is located in the groove 14. The meshing transmission between the locking block and the groove 14 prevents slippage when the synchronous belt 16 drives the rotating shaft 13 to rotate, ensuring that multiple guide rollers 15 rotate synchronously and preventing the film from being stretched or wrinkled due to speed difference.

[0032] The specification adjustment assembly includes an electric telescopic rod 17 fixedly connected to the inner wall of the guide groove 101 and an adjustment plate 18 fixedly connected to the output end of the electric telescopic rod 17. There are two specification adjustment assemblies arranged symmetrically. The electric telescopic rod 17 drives the adjustment plate 18 to move, thereby adjusting the distance between the two adjustment plates 18, so that the device can adapt to printing films of different widths and improve the practicality of the device.

[0033] A vertical plate 19 is fixedly connected to the upper surface of the film output cavity 10. The side surface of the rotating shaft 13 is rotatably connected to the vertical plate 19. The rotating shaft 13 is fixedly connected to the film output channel 8 through a bearing. The setting of the vertical plate 19 and the bearing reduces the shaking of the rotating shaft 13, reduces noise and extends service life.

[0034] A fixing plate 9 is fixedly connected to the side surface of the film output channel 8. A mounting plate 5 is movably connected to the lower surface of the fixing plate 9. A film printer body 1 is fixedly connected to the side surface of the mounting plate 5. A printing cavity 4 is provided on the front surface of the film printer body 1. A guide plate 2 is provided on the upper surface of the film printer body 1. A film inlet 3 is provided on the upper surface of the film printer body 1. The film output cavity 10 is connected to the printing cavity 4.

[0035] Bolts 6 are fixedly connected to the upper surface of mounting plate 5, and nuts 7 are threadedly connected to the side surface of bolts 6. Bolts 6 penetrate fixing plate 9, and the upper surface of fixing plate 9 contacts nuts 7. The film printer body 1 and film output channel 8 can be fixedly connected together by bolts 6 and nuts 7.

[0036] The working principle of this utility model is as follows: When printing film using this device, one end of the film is passed through the film inlet 3 of the film printer body 1 and enters the printing chamber 4. After the film printer body 1 is started, the film is printed, and at the same time, the drive motor 12 is started. The printed film enters the output channel 8. The drive motor 12 rotates and drives the guide roller 15 to rotate. The guide roller 15 guides the film during rotation so that it is exported from the output channel 8. When the width of the film changes, the electric telescopic rod 17 can be activated to adjust the distance between the adjustment plates 18 so that it is consistent with the width of the printed film.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
