The fully automatic mask folding and filling mechanism consists of: a frame, a hydraulic pump station, a lower crossbeam, vertical columns, a moving crossbeam, an upper crossbeam, a metering unit, a mask inlet, a filling nozzle, and a lifting assembly.
The frame is equipped with the hydraulic pump station and the lower crossbeam, while the lower crossbeam supports the vertical columns. These columns, in turn, hold the moving crossbeam, which is topped by the upper crossbeam. Mounted atop the upper crossbeam is the metering unit, which includes a measuring cylinder, a rotary valve, sprockets, a chain, and a positioning cylinder.
Several measuring cylinders are arranged along the upper crossbeam, each fitted with a rotary valve at its top. A sprocket is attached to the rotary valve, and the positioning cylinder is directly connected to the chain for precise movement.
The main hydraulic cylinder from the pump station is linked to the measuring cylinders, ensuring smooth operation. Meanwhile, the measuring cylinders are connected to the filling nozzles. Above the metering unit sits the mask inlet, which communicates with the measuring cylinders via the rotary valves.
Finally, the filling nozzles are fitted with a lifting assembly, driven by a lifting cylinder positioned on the lower crossbeam and mechanically connected to the frame.
Additionally, a bottle-blocking mechanism is installed on one side of the metering unit, while the lower crossbeam also features a dedicated metering adjustment assembly for fine-tuning the system’s performance.
The filling and sealing machine efficiently and precisely injects various materials—such as pastes, creams, and high-viscosity fluids—into flexible tubes, while simultaneously performing functions like in-tube hot-air heating, tube sealing, and applying batch numbers and production dates. This equipment is ideal for large-diameter plastic or composite tubes used in industries including pharmaceuticals, food, cosmetics, and daily chemical products.
A filling and sealing machine’s performance is determined by multiple interrelated parameters; thus, it’s impossible to fully describe the machine using just a single factor. The five fundamental parameters that characterize such a machine are shaft power (P), impeller discharge rate (Q), head pressure (H), impeller diameter (D), and filling speed (N). Specifically, the impeller’s discharge rate is directly proportional to the impeller’s flow coefficient, the first power of its rotational speed, and the cube of its diameter. Meanwhile, the shaft power consumed during filling is proportional to the fluid’s specific gravity, the impeller’s own power coefficient, the cube of the rotational speed, and the fifth power of the impeller diameter.
From the perspective of the filling and sealing mechanism, it’s the presence of fluid velocity differences that drives the mixing of fluid layers. Consequently, the filling process inherently involves fluid shear rates—factors like lhhaha620—that play a crucial role. Shear stress, as a type of force, is the primary driver behind phenomena such as bubble dispersion and droplet breakup in filling applications.
