[0002] Medical packaging bag films, as core materials for medical device and pharmaceutical packaging, must possess high barrier properties, biocompatibility, and sterility to ensure the safety and effectiveness of the packaged items during transportation and storage. Under the stringent regulations of the medical industry, the printing of medical packaging bag films not only displays basic information such as product name, specifications, production date, and instructions for use, but also accurately prints crucial information such as traceability codes, warning labels, and sterilization marks. This printed content directly relates to the compliance and traceability of medical products. Traditional manual printing or simple mechanical printing methods suffer from low efficiency, poor precision, and unstable quality, making it difficult to meet the large-scale, standardized production demands of the modern medical industry. Therefore, the research and development and manufacturing of automated printing equipment for medical packaging bag films are crucial, aiming to achieve efficient, accurate, and stable film printing, ensuring the quality and production efficiency of medical packaging products.

[0003] Currently, automatic printing devices for medical packaging bag films on the market come in various technological forms. Existing devices use flexographic or gravure printing technologies; the former is low-cost and easy to change plates, while the latter offers high printing quality. However, these devices are insufficient in cooling the printed roll, and rewinding after printing can cause information corruption on the still-hot film, resulting in incomplete or distorted printing information. Therefore, an automatic printing device for medical packaging bag films is proposed to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic printing device for medical packaging bag film, which aims to improve the problem that the heat dissipation effect of the printing device after printing is insufficient, which easily leads to incomplete or disordered printing information.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic printing device for medical packaging bag film includes a housing, an unwinding roller and a rewinding roller rotatably connected inside the housing, a control panel on the side wall of the housing, a printing machine inside the housing, a cooling assembly inside the housing, and a limit mechanism inside the housing. The cooling assembly includes a fan, a partition fixedly connected inside the housing, a base fixedly connected to the bottom of the partition, a fan sidewall fixedly connected inside the base, and exhaust vents on both sides of the housing.

[0007] As a further description of the above technical solution:

[0009] As a further description of the above technical solution:

[0010] A workbench is fixedly connected to the top of the partition, and the workbench is located directly below the printing machine.

[0011] As a further description of the above technical solution:

[0012] The box body is rotatably connected to a limiting roller, and multiple limiting rollers are provided and distributed on both sides of the worktable.

[0013] As a further description of the above technical solution:

[0014] An exhaust fan is fixedly connected inside the box.

[0015] As a further description of the above technical solution:

[0016] The box is rotatably connected to multiple conveying rollers, which are distributed on the upper and lower sides of the partition.

[0017] As a further description of the above technical solution:

[0018] The side wall of the box is provided with a viewing door, and the bottom of the box is fixedly connected with a support column.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, by combining the conveying roller and the fan, the conveying process of the film material is increased, so that the contact time with the cold air is increased, and the printed film material is cooled more quickly. This solves the problem that ordinary film printing machines lack cooling for overheated film material after printing, and the problem that rapid winding leads to reduced printing quality and blurry prints. This improves the stability of the equipment.

[0021] 2. In this utility model, the tension of the film material during the conveying process is improved by the cooperation of the clamping plate and the limiting roller, and the film material is precisely limited to prevent it from shifting or misaligning during operation, thus ensuring the stability of the printing operation. This solves the problem that ordinary film printing machines lack limiting during film material conveying, which can lead to film material shifting, printing errors, waste of film material, and the need to stop the machine for adjustment. This improves the accuracy and stability of the equipment. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-4This utility model provides an embodiment of an automatic printing device for medical packaging bag film, comprising a housing 1, an unwinding roller 4 rotatably connected inside the housing 1, and a take-up roller 5 rotatably connected inside the housing 1. The unwinding roller 4 and the take-up roller 5 are positioned on the same side, which facilitates feeding and taking up materials and reduces manpower. A control panel 6 is provided on the side wall of the housing 1 for operating the machine. A printing machine 11 is installed inside the housing 1, as well as a cooling assembly and a limit mechanism. The cooling assembly includes a fan 15, and a partition 9 is fixedly connected inside the housing 1 to optimize airflow. The layout separates the cooling system from the working area, preventing airflow from interfering with the printing process and providing mounting support for other components. A base 14 is fixedly connected to the bottom of the partition 9, and the side wall of the fan 15 is fixedly connected inside the base 14. The base 14 provides a stable mounting foundation for the fan 15, ensuring stable airflow direction and enhancing heat dissipation. This allows for rapid cooling after film printing and prevents the fan 15 from becoming loose and affecting cooling efficiency. Exhaust ports 7 are located on both sides of the cabinet 1, providing a channel for hot air to escape. These ports, in conjunction with the fan 15, form an air circulation system, accelerating the removal of hot air from the cabinet 1. The system introduces outside cold air to enhance the cooling effect and maintain temperature balance inside the chamber. A workbench 12 is fixedly connected to the top of partition 9, positioned directly below the printing press 11. This ensures precise alignment between the printing press 11 and the workbench 12, facilitating the operation of the printing press 11 and maintaining its stability during operation, thus improving printing quality and efficiency. An exhaust fan 10 is fixedly connected inside the chamber 1, and its auxiliary fan 15 enhances the exhaust effect, further accelerating the removal of hot air from the chamber 1, creating stronger air convection, improving overall cooling efficiency, and effectively reducing the internal temperature of the chamber 1. 1. Multiple conveyor rollers 8 are internally connected and rotate. The conveyor rollers 8 are distributed on the upper and lower sides of the partition plate 9. The conveyor rollers 8 are arranged in upper and lower layers to increase the contact between the printed film material and the air. With the help of the fan 15, the film material can be cooled down quickly. The side wall of the box 1 is provided with a viewing door 2, which makes it convenient for the operator to observe the internal situation of the box 1. The upper and lower viewing doors 2 can be used to feed and collect materials respectively. The bottom of the box 1 is fixedly connected with a support column 3 to improve the stability and height of the box 1. It keeps the bottom of the box 1 at a certain distance from the ground to facilitate air circulation and heat dissipation. At the same time, it prevents the bottom of the box 1 from getting damp and worn, thus extending the service life of the equipment.

[0031] Reference Figure 4 and Figure 5The limiting mechanism includes a limiting plate 20. A slide rail 18 is fixedly connected to the top of the partition 9, and the bottom of the limiting plate 20 is slidably connected to the top of the slide rail 18. The slide rail 18 provides a sliding track for the limiting plate 20, allowing it to move smoothly along a preset direction. This ensures accurate movement of the limiting plate 20 during position adjustment, preventing shaking or jamming and improving the precision of the limiting operation. A fixing block 17 is fixedly connected to the side wall of the slide rail 18, and a motor 16 is fixedly connected to the top of the partition 9. A bidirectional screw 19 is fixedly connected to the output end of the motor 16. The motor 16 provides power for the rotation of the bidirectional screw 19. By precisely controlling the speed and direction of the motor 16, the position of the limiting plate 20 can be accurately adjusted, making the limiting operation more automated and efficient. The side wall is threaded inside the limiting plate 20. The threaded connection allows the rotation of the bidirectional screw 19 to stably drive the limiting plate 20 to move. Utilizing the self-locking characteristic of the threaded transmission, the limiting plate 20 can be kept fixed after being adjusted to a suitable position, preventing displacement due to external forces. The bidirectional screw 19 is rotatably connected inside the fixing block 17, making the screw rotation smoother and ensuring that the limiting plate 20 can respond to the drive of the motor 16 in a timely manner to adjust its position. The housing 1 is rotatably connected to the limiting rollers 13. Multiple limiting rollers 13 are provided and distributed on both sides of the worktable 12, which can roll and limit the printing material. While guiding the material conveying, it prevents the material from deviating or serpentine during the conveying process, improves the tension effect, and ensures that the material is conveyed smoothly along the predetermined path.

[0032] Working principle: First, the film material is placed on the unwinding roller 4. The film material first passes through the first limiting roller 13. Based on the film width, the motor 16 is started. When the motor 16 rotates, it drives the bidirectional screw 19 to rotate. The bidirectional screw 19 rotates inside the fixed block 17, causing the two limiting plates 20 to move closer to the center via the slide rail 18, tightening the limiting plates 20 to the width of the film material, thus limiting the film material. The film material passing through the limiting mechanism will pass through the worktable 12. After printing by the printing press 11, it will pass through the second limiting roller 13, and then... The film material passes over the first conveyor roller 8, then under the second conveyor roller 8, and then through the cooling area. The fan 15, fixed in the base 14, blows air to cool the film material. The hot air blown out is discharged from the exhaust port 7. After being cooled, the film material passes under the third conveyor roller 8 and is fed onto the upper side of the take-up roller 5. During operation, the exhaust fan 10 can be turned on to ventilate and cool the inside of the machine and remove the hot air. The operator can check the feeding and taking-up status through the upper and lower viewing doors 2 and complete the feeding and taking-up work.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
