Summary
Taoxing Printing Equipment, with its semi-automatic curved surface screen printing machine as its core, overcomes the challenges of curved surface printing through professional screen printing technology, ensuring that fire extinguisher labels are clear, durable, and precise, thus improving efficiency in emergency situations. The following details the key points of the entire process.
I. Core Technological Challenges and Solutions
Fire extinguisher cylinders are mostly circular and curved, making it easy for markings to become misaligned, blurry, or lacking in adhesion.
Challenge 1: Uneven printing pressure on curved surfaces results in rough edges on the fonts;
Challenge 2: Bottle positioning deviation causes misalignment of label position;
Challenge 3: Insufficient ink curing leads to easy wear and peeling.
To address the above issues, Taoxing adopted a customized solution: The automatic positioning system of the fire extinguisher screen printing machine calibrates the bottle angle to ensure consistent adhesion throughout the printing process; high-tension screens (tension maintained at 25–30N) and special fire safety marking inks are selected, with viscosity controlled within the standard range; and an automatic balancing squeegee adjusts the pressure and angle (45°–60°) to resolve blurring issues; after printing, the ink is processed using rapid drying equipment to ensure thorough curing and improve wear resistance.
II. Core Equipment Used and Its Advantages
The core equipment includes Taoxing TX- 600S and TX-1100S semi -automatic curved surface screen printing machines and matching drying equipment. The semi-automatic curved surface screen printing machine adopts microcomputer control, which can realize automated operation of ink scraping, ink return, and worktable lifting. The printing speed reaches 500 PCS/H, and it is suitable for fire extinguisher bottles with a diameter of Φ150mm and above . The screen frame and worktable can be adjusted in multiple directions, balancing precision and flexibility.
III.Standard Operating Procedures
1. Pre-treatment: Clean the surface of the fire extinguisher bottle to remove oil and oxide layers, and ensure the printing substrate is clean;
2. Equipment debugging: Install the screen according to the marking size, fine-tune the distance between the screen frame and the bottle body through the fire extinguisher screen printing machine, and set the printing speed, pressure and drying parameters;
3. Trial Printing and Calibration: Use semi-finished bottles to perform trial printing, check the clarity and positional deviation of the markings, and optimize the parameters;
4. Batch printing: Start the semi-automatic curved surface screen printing machine to automatically complete the feeding, printing, and ink return processes;
5. Curing and Drying: After printing, the ink is processed by the drying equipment on the unloading platform to ensure complete curing;
6. Quality inspection and sorting: Check the integrity and adhesion of the labels, and reject unqualified products.

IV.Operating Precautions and Maintenance
Precautions during operation: Before starting the machine, check the air source (6 bar) and power supply to ensure that the equipment is operating normally; do not allow hard objects to hit the touch screen; ink mixing must be precise and different types should be avoided.
screen , scraper, and guide rails daily ; drain any accumulated water from the filter cup; and lubricate bearings and other components with dedicated lubricating oil. Check electrical wiring and belt wear weekly, and calibrate printing accuracy weekly. Perform deep cleaning and software calibration monthly. If the equipment is to be stored for an extended period, wipe it clean and store it in a dry, well-ventilated environment. In case of malfunction, immediately stop the machine and disconnect the power; contact a professional for repair. Do not attempt to disassemble any parts yourself.
