Market development of automatic filling and sealing machine for Beite packaging suction nozzle bag

Pubdate:2020-05-16 15:41:46 Hits:579

Soft packaging with mouth refers to the installation (generally by heat sealing) of a hard mouth of low-pressure polyethylene (HDPE) with a rotating cap on the soft packaging bag. The soft packaging bag has the function that the bottle packaging can be opened and closed repeatedly.

The existing composite film bags of various materials can be made into soft packaging bags with mouth by adding a hard mouth.

In general, the manufacturer will choose to install a hard mouth on the self-supporting bag, so that the soft package is more similar to the bottle packaging function and form, which is convenient for the user to use.

According to the installation position of the mouth, the soft packaging bag with mouth can be divided into two types: vertical installation bag with mouth and inclined installation bag with mouth. The vertical installation is to install the hard nozzle in the middle of the top of the bag. Its shape and function are similar to that of the general bottle packaging, and it is applicable to the packaging capacity of less than 1000ml. The inclined mouth installation is to cut the upper left corner of the packaging bag to a 45 degree angle, and install the hard mouth on the cutting surface, so that the mouth axis is 45 degrees with the bag axis. The shape and function of the soft packaging bag are similar to that of the general hard plastic barrel packaging, which is applicable to the packaging capacity of more than 500ml.

According to the shape of the plastic mouth installed on the bag, the soft packaging bag with mouth can be divided into long mouth type and short mouth type. The long mouth type refers to that the plastic mouth has a long straw besides the screw mouth sealing part and the heat sealing part. When the long mouth is installed in the soft packing bag, the straw part is inserted into the bag, so that the consumer can use the mouth to suck the liquid in the bag. This kind of bag is generally suitable for the use of liquid beverage food, but also for the automatic extraction of printing ink packaging. The short nozzle type refers to that the plastic nozzle has only two parts: the rotating mouth sealing part and the heat sealing part. After the nozzle is installed in the soft packaging bag, it is suitable for dumping or extruding to take out the package inside the bag. It can be widely used in the packaging of liquid, particle, powder and other types.

Soft packaging bag with mouth was born in Japan and Germany in the middle and late 1980s. With the development of the technology and equipment of self-contained bag making, the technology and equipment of automatic mouth filling and sealing machine, the packaging has been popularized all over the world since the late 1990s. In addition to the advantages of convenient opening and multiple sealing of bottle and barrel packaging, soft packaging with mouth has the advantages of less packaging material consumption, high printing quality, low packaging storage and transportation costs, and small waste disposal volume, which is known as environmental protection packaging. According to statistics, compared with the same capacity of bottles and barrels, the consumption of raw materials for soft packaging with mouth is reduced by more than 30%, the storage and transportation cost of packaging materials is reduced by more than 60%, and the waste treatment capacity is reduced by more than 5 times. These irreplaceable advantages determine that soft packaging with mouth has a great development prospect.

2、 Working principle of automatic fitting and sealing season

The automatic mouth sealing machine is a white dynamic equipment which can install the plastic hard mouth into the plastic bag and weld the plastic mouth and the plastic bag together. The use of automatic mouth sealing machine has the advantages of high production efficiency, beautiful product appearance, high heat sealing strength, avoiding hand contact with mouth and bag, safety and health, etc.

There are two types of automatic filling and sealing machine: one is the machine which uses the nozzle to locate and realize multi position transmission, and then packs the bag into the nozzle and welds it. It is mainly used for long nozzle suction nozzle type and vertical installation welding nozzle. The other is the machine which uses bag positioning and multi position transmission to insert the nozzle into the bag and weld. It is mainly used for short nozzle type and inclined nozzle type installation.

The automatic mouth sealing machine is mainly composed of the following parts:

1. Automatic feeding system of vibrating disc: the system can automatically arrange the plastic hard nozzles and transmit them to the upper nozzle device in a specific way. In order to enhance the heat sealing strength, the preheating function of the nozzle should be added in this system.

2. The automatic mouth sealing machine with the mouth positioning of the upper mouth system uses the air cylinder to push the mouth into the bayonet of the conveyor; the automatic mouth sealing machine with the bag positioning uses the manipulator to insert the mouth into the bag.

3. Conveying system: it is used to transport the mouth or bag and the installed bag with mouth according to the fixed length of the station, so as to realize the functions of angle cutting, mouth mounting, spot welding, heat sealing, cold setting, detection, etc. The transmission system is driven by a servo motor.

4. The upper bag system is generally composed of a bag bin, a bag taking device and a bag delivering device, which is used to take out plastic bags from the bag bin and transmit them to the main transmission line.

5. Heat sealing system: the system is composed of multiple sets of heat sealing cylinders, which can complete spot welding and multiple heat sealing and cold setting functions.

When the automatic mouth sealing machine is working, it can automatically take out the plastic bag from the bag bin, transfer it through the transmission system at multiple stations, and successively complete the corner cutting, mouth pulling, spot welding, multiple heat sealing, cold setting and offline functions.

3、 Comparison of models at home and abroad in automatic fitting and sealing season

The automatic mouth sealing machine is the key equipment for the production of soft packaging with mouth. The use of the automatic mouth sealing machine can not only greatly improve the production efficiency, ensure the sealing strength, but also avoid manual contact with the suction nozzle, so as to meet the requirements of food hygiene.

There are two types of automatic mouth sealing machines: one is vertical automatic mouth sealing machine, which is mainly used to produce vertical mouth bag; the other is inclined mouth automatic mouth sealing machine, which is mainly used to produce inclined mouth bag.

4、 Application status of domestic market

With the soft packaging with mouth gradually promoted in China, automatic mouth sealing machine is also selected by many packaging manufacturers. At present, the domestic imported models include Japanese Yanzheng psm-30c, psm-75k and Japanese total st-24. Ncal601-30 and ncal620-30 developed by Zhongshan XINHONGYE Automation Industry Co., Ltd. have become the first choice of many domestic packaging manufacturers. The two models of XINHONGYE company not only have the main performance up to the level of foreign products, but also have been exported for more than one third of the price of imported machines. The two products of the company can meet the requirements of vertical and inclined mouth
