Overview of the basic classification of packaging machinery

- Dec 31, 2018-

Overview of packaging machine: The function of the packaging machine will automatically seal the product with plastic bag to protect and keep fresh.

The process includes bag making, packaging, inflation, exhaust, date coding and other major processes. In addition, the packaging also includes processes such as metering or adding automatic materials to the packaging machine. The use of mechanical packaging products can increase productivity, reduce labor intensity, meet the needs of large-scale production, and meet other requirements such as sanitation and preservation.

Packaging machine classification: There are many types of packaging machines, and many classification methods have their own characteristics and scope of application, but they all have their limitations. From the general situation of packaging machinery in the world, the more scientific classification method is classified according to its main function, which can grasp the essence of things. From different viewpoints, there are many kinds, according to the product status, there are liquid, block, and granular packaging machines; according to the packaging, there are inner packaging, outsourcing packaging machine; according to the packaging industry, there are food, daily use Chemical, hardware parts, textiles and other packaging machines; according to the packaging station, there are single-station, multi-station packaging machine; according to the degree of automation, there are automatic packaging machines, also semi-automatic and so on. According to the form of sealing, it can be divided into back sealing type, three side sealing, four side sealing, triangular division and so on. According to the product form, it can be divided into pillow packaging machine, vertical packaging machine, vacuum packaging machine, sealing machine, shrinking machine, sealing and cutting machine and so on.

Pillow packing machine
1. Scope of application
This machine is suitable for biscuits, moon cakes, rice crackers, snow cakes, egg yolk pies, chocolate, bread, instant noodles, medicines, navel oranges, lemons, citrus, vegetables, jujubes, candy and other regular objects. (Material form needs to be solid)
2. Structural features
This machine adopts Japan Matsushita PLC (core controller), double inverter control, the bag length can be set and cut, no need to adjust the air, one step in place. Temperature independent PID control sealing and cutting, suitable for packaging film of various packaging materials, high-sensitivity electric eye color marking system, color marking tracking in one step.
3. Optional device
1. Date coding machine inkjet printer
2. Spray alcohol device, venting device, round hole device, dotted line device
3. Anti-cutting device, bag-connecting device, etc.
4. Automatic feeding device, automatic automatic ironing device for roll paper.
5. Automatic inflator, nitrogen generator, oil-free air compressor, cold dryer, ordinary air compressor

Vertical packaging machine
1. Scope of application
This machine is suitable for soup, granules, desiccant, monosodium glutamate, sugar, oatmeal, powder, soy flour, milk powder, shampoo, face cream, condiment, chocolate, screws and other scattered materials, packaging of small materials. (Materials can be liquid, granule, powder, hardware, pills, etc.)
2. Structural features
This machine adopts photoelectric eye control system, from automatic metering, filling and bag making, date coding to product output.
3. Optional device
1. Ribbon coding machine
2. Automatic feeder automatic weighing machine automatic metering device
3. Bag-connecting device
4. Automatic inflator, nitrogen generator, oil-free air compressor, cold dryer, ordinary air compressor

Vacuum packaging machine
1. Scope of application
In the food industry, vacuum packaging applications are very common, a variety of cooked products such as chicken legs, ham, sausages, etc.; pickled products and soy products, preserved fruit and other foods that need to be fresh.
2. Machine characteristics
1. Excluding some of the (oxygen) air in the packaging container can effectively prevent food from spoiling.
2. The use of packaging materials with excellent barrier properties (air tightness) and strict sealing technology and requirements can effectively prevent the exchange of substances in the package, thereby avoiding weight loss and loss of taste, and preventing secondary pollution.
3. The gas inside the vacuum packaging container has been eliminated, and the heat conduction is accelerated, which can improve the heat sterilization efficiency and avoid the rupture of the packaging container due to the expansion of the gas during the heat sterilization.
3. Optional device
1. Date coding machine inkjet printer
2. Spray alcohol device, venting device, round hole device, dotted line device
3. Anti-cutting device, bagging device, etc.

1. Filling machine: A filling machine is a packaging machine that loads a precise amount of packaging into various containers. The main types are:

1 volumetric filling machine. Including measuring cup, intubation, plunger, material level, screw, timing filling machine.

2 weighing filling machine. Including intermittent weighing, continuous weighing, weighing - centrifugation and other filling machines.

3 counting filling machine. Includes single-piece counting and multi-piece counting filling machines.

2. Sealing machine: The sealing machine is a machine for sealing a container filled with packaging materials. The main types are:

1 No sealing material sealing machine. Including hot pressing, cold pressing, fusion welding, plug-in, folding and other sealing machines.

2 There is a sealing material sealing machine. Including rotary, rolling, crimping, press-fit and other sealing machines.

3 has an auxiliary sealing material sealing machine. Including tape type, bonding type, nailing type, ligation type, stitching type and other sealing machine.

3. Wrapper: The wrapper is a packaging machine that wraps the package in whole or in part with a flexible packaging material. The main types are:

1 full wrap wrapper. Including wrap, cover, body, seam and other wrappers.

2 half-wrapped wrapper. Including folding, shrinking, stretching, winding and other wrapping machines.

4, multi-function packaging machine: This type of packaging machine has two or more functions. The main types are:

1 filling and sealing machine. It has two functions of filling and sealing.

2 molding filling and sealing machine. It has three functions of forming, filling and sealing. The types of molding include bag molding, bottle molding, box molding, blister molding, and melt molding.

3 stereotype filling and sealing machine. It has the functions of shaping, filling and sealing. Stereotype

4 double-sided sealing machine. It can seal both the cover and the bottom. When sealing, the box can be placed sideways or placed.

5. According to the position and number of tapes sealed:

1I type sealing machine. It is sealed with a piece of tape at the outer lid of the box and the outer flap seam of the bottom. This sealing is simple in operation but poor in sealing.

2H type sealing machine. It is based on the I-type sealing, that is, two tapes are sealed at both ends of the I-type sealing tape, and the shape is like H, so it is called H-type. It increases box strength and sealing performance but at a higher cost.

6. Classified according to the degree of specialization:

1 universal sealing machine. It can adjust certain mechanisms to change the size of the sealing machine to accommodate the sealing of boxes of various sizes. It adapts to a wide range and is a commonly used sealing machine.

2 special sealing machine. It can only seal a box of a certain size, and it has a fast sealing speed and is suitable for large-volume sealing operations.

3 random type sealing machine. It is a highly automated sealing machine within the specified size range, and the relevant agencies can automatically change to suit the sealing needs of different sizes of boxes.
