Description

Technical Field

[0001] This application relates to the field of filling machine technology, and in particular to a coding device for a filling machine. Background Technology

[0002] In existing technologies, inkjet printer printheads are typically installed inside the machine. However, due to limited internal space, the printheads are often installed at an angle. This installation method results in poor printing quality, uneven font size, and susceptibility to membrane vibration. Furthermore, the printhead installation position in existing technologies often fails to balance printing quality and sterile environment requirements. For example, while a printhead directly facing the membrane ensures printing quality, it prevents the sterile room door from closing, compromising the sterile environment. Membrane path design: Existing technologies often feature simple membrane path designs, typically with only two membrane rollers. The membrane is prone to vibration during operation, leading to unstable printing quality. This design cannot effectively control membrane tension, thus affecting the quality of the markings. The vibration problem in existing technologies remains unresolved, resulting in inconsistent font size during marking and impacting overall product quality. Inkjet printer retrofit solutions: Retrofit solutions for existing inkjet printers are usually limited to changing the printhead type (e.g., printhead type) or adjusting the printhead position. However, these solutions often fail to simultaneously address the issues of printing quality and sterile environment.

[0003] Existing technologies have the following technical problems: improper printhead installation position leads to poor printing effect, imperfect film path design leads to film vibration, the inkjet printer modification scheme cannot meet the requirements of printing effect and sterile environment, and the inkjet printing effect has poor stability.

[0004] Improper printhead installation leads to poor printing results: In existing technologies, inkjet printer printheads can typically only be installed at an angle, resulting in uneven font size and unsatisfactory printing quality. While positioning the printhead directly opposite the membrane can improve printing results, it prevents the sterile room door from closing, compromising the sterile environment and posing a safety hazard.

[0005] Imperfect membrane path design leads to membrane vibration: In existing technologies, the membrane path design is relatively simple, usually with only two membrane rollers. The membrane is prone to vibration during operation, resulting in unstable printing effects. Membrane vibration can cause inconsistent font sizes during coding, affecting the overall product quality.

[0006] Inkjet printer retrofit solutions cannot simultaneously address both printing quality and a sterile environment: Existing technologies typically limit inkjet printer retrofit solutions to changing the printhead type (e.g., printhead type) or adjusting the printhead position. However, these solutions often fail to solve both printing quality and sterile environment issues at the same time. While placing the printhead outside the machine can improve printing quality, it prevents the sterile room door from closing, thus compromising the sterile environment.

[0007] The coding effect is unstable: In existing technologies, the coding effect is unstable, mainly due to unreasonable printhead installation position and imperfect film path design, resulting in inconsistent font sizes during printing and affecting the overall product quality. Coding machine retrofit solutions typically do not consider film path optimization, leading to suboptimal printing results.

[0008] Inconvenient operation: In existing technologies, the printing position of inkjet printers is not designed reasonably, making it difficult for operators to observe the printing effect on the conveyor belt. They need to manually flip the product to see the printed content, which increases the complexity of operation. Summary of the Invention

[0009] This application aims to solve the problem of membrane vibration caused by imperfect membrane path design, and further designs a coding device for a filling machine.

[0010] The technical solution proposed in this application is:

[0011] A coding device for a filling machine includes a large film roller, a rubber ring, a bracket, a nozzle, and a roll of film;

[0012] There are 7 large film rollers, which are set on the worktable and arranged in the shape of the Big Dipper. The 7 large film rollers are defined as the first film roller, the second film roller, the third film roller, the fourth film roller, the fifth film roller, the sixth film roller, and the seventh film roller in sequence.

[0013] The film roll is mounted on the worktable via a film roll shaft and is located to the lower right of the first film roller. The film roll passes sequentially around the first film roller, the second film roller, the third film roller, the fourth film roller, the fifth film roller, the sixth film roller, and the seventh film roller.

[0014] Rubber rings are fitted on the second and sixth film rollers, and the film roll contacts the rubber rings;

[0015] The nozzle is mounted on the worktable via a bracket and is positioned directly opposite the second film roller.

[0016] Furthermore, a coding device for a filling machine also includes an angle encoder, which is installed on the side of any large film roller. The lower end of the angle encoder is provided with a contact plate, which contacts the outer circumferential surface of the third film roller.

[0017] Furthermore, the coding device is placed in a sterile room.

[0018] Furthermore, a coding device for a filling machine also includes a small film roller, which is positioned close to the third film roller.

[0019] Furthermore, all seven large and small film rollers are smooth, rotatable aluminum alloy cylinders.

[0020] Furthermore, the angle encoder is connected to the workbench via a plate and a support column, with a spring installed between the support column and the bottom surface of the plate.

[0021] Furthermore, the coding device is equipped with rollers at the bottom for easy maintenance.

[0022] This application has the following beneficial effects:

[0023] This application proposes a coding device for a filling machine. Through a series of optimization measures, this application significantly improves the coding effect, ease of operation, and product quality. First, by adjusting the printhead position to be directly aligned with the printing position of the film roll, uniform font size is ensured, significantly improving the coding effect. Second, the film path design is improved by adding a film roller and using a rubber ring to fix the film roll, effectively reducing film vibration and ensuring film stability during printing, further improving coding quality. Furthermore, by moving the printhead to a sterile chamber and adding a fixing bracket, the requirements of both coding effect and sterile environment are balanced, avoiding environmental contamination and ensuring product quality. Finally, an angle encoder monitors the film roll travel speed in real time and synchronizes it with the coding speed, avoiding problems such as font distortion and improving the stability of the coding effect. The overall solution not only optimizes the coding effect but also improves operational convenience. Operators can clearly observe the coding effect without manually flipping the product, significantly improving production efficiency. The coding effect is stable. With the addition of an angle encoder and a well-designed film path after the film roller is installed, the font size is consistent and complete without deformation during printing, achieving the best coding state and greatly improving the product appearance quality.
