Vertical Packaging Machine

A Vertical Packaging Machine, also known as a vertical form-fill-seal (VFFS) machine, is a versatile piece of equipment used in the packaging industry for the efficient and automated packaging of a wide range of products. This type of packaging machine is capable of forming, filling, and sealing bags or pouches in a vertical orientation. 

Use process:

No-load test run: No-load test run shall be carried out after installation and commissioning of automatic filling and packing machine. During operation, power on and check each operating unit in turn to ensure that each no-load action is correct. The mechanical operation part and pneumatic control part shall operate flexibly and stably without obvious vibration and abnormal noise, and the action of each component shall be coordinated. At the same time, it is required to check the lubrication of motors and bearings. It is strictly prohibited to operate without oil. During no-load test run, the bearing temperature rise shall not exceed 25K. After the no-load operation is stable, the test run with materials can be started.

Constant feeding: the full-automatic filling and packing machine realizes constant feeding through the PLC control system. The feeding device usually adopts double valve filling structure and is driven by servo motor to ensure uniform feeding speed. The equipment is controlled by fast, medium and slow feeding in three stages. At the beginning, all filling valves are opened for fast filling. When the set value is reached, the equipment is switched to medium filling. Finally, fine feeding is carried out by slow filling to the target weight. By monitoring the filling weight in real time and adjusting the feeding speed through feedback, the feeding process is stable and uniform.

Automatic discharging: After the filling is completed, the full-automatic filling and packing machine automatically executes the discharging process. The discharging mechanism drives the main shaft to rotate at high speed by the motor through the belt pulley to pull out the materials quickly. When the material reaches the calibrated weight, the discharge nozzle will automatically close. Then the electromagnet receives the induction signal to actuate, the bag pressing device acts, the automatic bag dropping device works, the packaging bag automatically falls off and inclines outward to leave the packaging machine. The whole discharging process is controlled by PLC in the whole process without manual intervention.

Safety certification: The equipment has passed the CE certification, ISO9001 certification, patent certification, etc. and is sold in many countries such as Europe, Europe, America, Asia and Southeast Asia.

Durability and versatility

Durable quality: key parts of the equipment, such as filling valves, sealers and cutters, are made of high-strength and wear-resistant stainless steel. After heat treatment, the service life is greatly extended to ensure long-term stable operation. The rack is welded and aged as a whole, with sufficient rigidity and deformation resistance. Continuous no-load and strip fatigue tests are conducted before delivery to ensure no failure under 24h continuous working conditions. Overload protection, shortage alarm and other multiple protections are provided to effectively avoid misoperation damage, and the design life of the whole machine is more than 10 years.

Packaging structure (core): the core packaging structure of the filling and packaging machine adopts the vertical bagging - filling - sealing integrated layout. The former rolls the flat film into a cylindrical shape, and the longitudinal sealing wheel realizes back sealing or overlapping sealing. The filling pipe is extended into the bag, and the upper and lower seals are carried out by the transverse sealing mechanism after the blanking is completed. Meanwhile, the cutter completes the fixed length cutting. Key actuating parts are independently driven by servo motor, and sealing pressure and temperature can be accurately adjusted to ensure sealing strength. The whole packaging structure is compact, the action sequence of each station is precisely controlled by PLC, and the bag type is neat and the sealing is beautiful during high-speed operation.

Modularization design: the automatic packaging machine adopts the modularization concept, including membrane module, forming module, filling module, sealing module, cutting module and discharging module. Each module is assembled and debugged independently. The user can quickly change the former, filling tube or sealing mould according to the packaging requirements, so as to realize the switch of bag type or specification. Modules are connected through standard electrical interface and mechanical quick assembly, which is convenient for assembly and disassembly and greatly shortens maintenance and cleaning time. In case of failure of a module, it can be dismantled and repaired separately, which will not affect the normal use of other units and significantly improve the utilization rate and flexibility of equipment.

Simplified operation process

The operation process of the automatic filling and packing machine is extremely simplified. The equipment is equipped with PLC touch screen HMI, all parameters (such as filling volume, sealing temperature, bag length and speed) can be digitally preset and stored as recipe, and can be called by one key when switching products. Only press the start button after startup, the equipment will automatically complete the whole process of film supply, bag making, filling, sealing, cutting and discharging without manual intervention. During the operation, the system conducts real-time self-inspection, automatically shuts down and gives audible and visual alarm in case of film loss, material shortage or fault, and the screen displays the fault location and solutions. Regular supplement of packaging film and materials is only required for daily operation, and the residue at the sealing part shall be cleaned; The fast assembly structure is adopted for specification switching. The former and filling tube can be replaced without tools. The overall replacement time is controlled within 10 minutes, greatly reducing the technical requirements for operators.

Frequently Asked Questions

How to solve the problem of insecure sealing or air leakage during the operation of automatic filling and packing machine?

Most of the causes are too low sealing temperature, insufficient pressure or material particles on the sealing surface. Properly increase the heat seal temperature (2-5 ℃ for each time) and increase the sealing pressure; Check whether the sealing silicone strip is smooth and aged. If the powder is clamped, adjust the cutting time to ensure that the material is completely put into the bag before sealing, and clean the residual dust in the sealing area.

How to solve the problem of inaccurate measurement of automatic packaging machine (large weight deviation)?

The cause may be a change in material density, an unstable hopper level, or a load cell zero drift. The weighing system needs to be re-calibrated and zeroed; Keep the material level in the hopper constant (not less than 1/3); Check whether the screw or gauge cup feeding mechanism is worn, and replace the screw or adjust the volume compensation parameters if necessary.

Mode of maintenance:

Daily maintenance: check whether the air source pressure and power voltage are normal before starting the machine every day. Clean the residual dust and materials at the seal to ensure that the sealing surface is clean and free of material inclusion; Wipe the lens of photoelectric sensor to prevent dust from affecting bag length detection. Check the knives for obvious wear or sticking and simply clean the edges. Lubricate each sliding guide rail and opening/closing connecting rod, and add appropriate food grade lubricating oil. Discharge the accumulated water in the air filter after shutdown, turn off the main power supply and clean the surface of the touch screen..

Regular maintenance:

Check the oil level of the reducer every week, and add gear oil in case of insufficiency; Fasten all electrical terminals to prevent looseness and heating; Check the abrasion degree of traction wheel, cutter and sealing rubber strip, and replace if necessary. Calibrate the zero point of the weighing sensor every month, and clean the residual materials on the inner wall of the hopper and the screw feeding mechanism; Check whether the sealing ring of each cylinder is aged and leaked, and replace it in time. Completely inspect the sealing temperature sensor and heating tube every quarter to ensure accurate temperature control; Clean the dust in the electric control cabinet, check the operating state of the cooling fan and ensure the service life of the electrical components.
