Filling machines are a category of packaging equipment designed to dispense precise quantities of liquids, pastes, powders, or granules into containers. The core requirements are accurate dosing, high-speed filling, and leak-free operation. Filling machines from Jiangsu Zhongtai are versatile enough to handle a wide range of products-from everyday aqueous solutions and pastes to more challenging, corrosive substances like toilet cleaners or sodium hypochlorite (bleach) disinfectants.
Issues such as inaccurate dosing or component damage often stem from a lack of attention to operational details. To get the best performance out of this equipment, operators must be thoroughly familiar with the touchscreen interface and the piston-based dispensing system, while also ensuring that routine production and maintenance are carried out with care.
Let's take a look at the key precautions to keep in mind when operating the machine.
Before starting the machine, do not initiate operation immediately; instead, verify all conditions first. The equipment operates on a 380V power supply (supporting 50/60Hz)-ensure a stable ground connection. Maintain the air supply pressure between 0.6 and 0.8 MPa, and inspect air hoses for signs of aging or leaks. Be mindful of the materials for which the machine is designed; for instance, standard piston-filler models should not be used for long-term filling of highly corrosive liquids. If handling corrosive substances, confirm that all corrosion-resistant plastic components and seals are free from cracks or degradation. Additionally, verify that the bottle specifications-specifically diameter and height-fall within the equipment's operational parameters, and clear any debris from the hopper and conveyor. Filling volume is primarily adjusted by modifying the piston stroke; before commencing full-scale production, perform several test runs to ensure consistent measurement accuracy before switching to automatic mode.
Once the machine is running, it should be monitored by personnel on-site. Never remove safety guards for convenience, and keep hands away from moving parts such as filling heads and conveyor belts. Pay close attention to the machine's operation; if you hear unusual noises, observe product dripping, or notice inconsistent filling volumes, press the emergency stop button immediately. Disconnect both power and air supply before troubleshooting-never continue production while a fault exists. Do not allow the material in the hopper to run too low, as a low liquid level can draw in air, which will compromise filling precision. When switching to a different product, thoroughly clean the hopper, piping, and nozzles to prevent cross-contamination. For high-viscosity products like honey or sauces, reduce the piston speed to avoid excessive load and mechanical wear. When handling corrosive substances (such as disinfectants), operators must wear gloves and protective eyewear to prevent injuries from liquid splashes.
At the end of each production day, thorough and careful cleaning is essential. Never use water to wash areas containing electrical controls or PLC touchscreens; simply wipe the machine's exterior housing with a damp cloth. Empty and disassemble the hopper, cylinder, and filling nozzles to clean out any remaining product; for food or pharmaceutical production, ensure these components are also properly sanitized. Seals and pistons are consumable parts-monitor them regularly for wear, and replace them promptly if they show signs of aging or leakage, as failure to do so will compromise filling accuracy. For pneumatic components, check the oil level in the lubricator periodically, and apply an appropriate amount of lubricant to moving parts-taking strict care to ensure that no lubricant enters the product piping.
Whenever the machine requires disassembly for maintenance, it must be disconnected from both power and air supplies. Such tasks should only be performed by personnel familiar with the equipment; do not alter the internal programming of the touchscreen. Zhongtai equipment comes with a one-year warranty, covering the free replacement of parts damaged through no fault of the user; however, damage resulting from improper operation is not covered. If the machine is to be left idle for an extended period, clean and dry all piping, and cover the unit to protect it from dust. By staying attentive to the machine's operating status and adhering to standardized operating procedures, you can maintain consistent filling accuracy, minimize downtime for repairs, and ensure the equipment performs to its full potential.
