A plastic bag making machine is a machine for crafting colorful plastic bags or other material bags, designed for processing a range of plastic bags in various sizes, densities, and with additional features. The examination of the plastic bag making machine is crucial for ensuring the quality and functionality of the final product.
Maintaining consistent material pressure and directly controlling pressure fluctuations are vital for enhancing the efficiency and quality of the plastic bag making machine. Pressure discovery serves as the foundational premise for pressure control. Traditional machines feature two types of pressure detectors: direct and circular dimension detectors. Direct measures use bearing-type pressure detectors, akin to the excitation coil and secondary coil of a piezomagnetic pressure detector. The secondary coil acts as an inductor, generating an AC voltage signal proportional to the mechanical force when subjected to stress. This signal, after processing, provides a pressure reading. Varistor-type pressure detectors are installed to measure vertical pressure, with an amplifier used to convert the full-ground voltage force and dimension signal into a radial force reading suitable for digital display or as a setpoint for closed-loop control. Splint spring micro-displacement pressure detectors are also utilized, offering a wide detection range, fast response, and good linearity. However, they cannot absorb peak pressure values, which can lead to significant strip pressure changes during explosive disturbances.
The circular pressure discovery system is a position control mechanism, with the floating comber pressure discovery being commonly used. When the machine's pressure is stable, the material belt pressure balances with the cylinder force, centering the floating comber. Pressure changes cause the comber to move, and a potentiometer detects this movement, feeding back the position signal to the pressure regulator for control signal adjustments.
The integrated pressure discovery system of the Plastic Bag Making Machine, combining direct and circular measurements, can simultaneously detect the floating comber's position signal and the electrical pressure signal from the detector. This system offers excellent buffering and smoothing effects, along with high precision and repeatability in closed-loop control. There is also a system that measures pressure based on the roll's periphery, with a proximity switch detecting roll speed to calculate rewinding or unwinding adjustments for pressure adaptation.
During the conveying process, vertical positional deviation may occur due to various reasons such as uneven force, material consistency, and roller roundness. Timely online deviation discovery is essential. In the past, with lower machine speeds, operators manually adjusted material deviation based on direct observation. Nowadays, photoelectric detectors, known for their simple structure, reliable performance, high precision, and fast response, are used to track the boundary lines of different value areas on the packaging material's edge. They measure the offset between the actual and set positions, convert this offset into an electrical signal, and after comparison, calculation, and assessment, send instructions to the servo regulator. This action controls the motor that drives the deviation-correcting and guiding medium, returning the strip to the set position for automatic shadowing and adaptation in conveying.
