Product introduction:

Liquid packaging machine is a liquid packaging machine with high packaging efficiency and good edge sealing effect. It is mainly used for packaging liquid seasonings. It can accurately measure and weigh the packed materials, reducing the subsequent weighing steps. , The equipment uses a multi-layer seal design to ensure that there is no dripping after filling.

Introduction of automatic liquid packaging machine:

 This machine is widely used in milk, soy milk, various beverages, soy sauce, vinegar, rice wine and other liquids. After ultraviolet sterilization, bag forming, date printing, quantitative filling, sealing and cutting, the product is beautiful and reliable. The whole machine adopts stainless steel structure to ensure that it meets international health standards. It can use color printing composite film and photoelectric detection to ensure complete patterns.

Function of liquid packaging machine:

Shanghai liquid packaging machine is made of stainless steel, with high-position balance tank or self-priming pump for quantitative filling, direct heat sealing and cutting, convenient and reliable adjustment of bag size, packaging weight, and sealing and cutting temperature, production date ribbon printing, side sealing, back sealing, Photoelectric tracking. The adjustment of packaging bag heat sealing, bag delivery length, packaging weight, heating temperature is simple and reliable, continuous filling precision is high, packaging speed is fast, and maintenance is convenient. It is the ideal equipment for users to get rich. Now it is developing rapidly in food and medicine. , Beverage, daily chemical, cosmetics and other industries.

The performance characteristics of the vertical bag water automatic packaging machine are as follows

1. The main machine of 420 packing machine is used in the vertical automatic packing machine for bagged water, which is made of 304 stainless steel. Stainless steel has the characteristics of anti rust and anti-corrosion;

2. The packaging machine adopts servo double film pulling system to ensure the smooth transmission of packaging film and smooth bag formation;

3. The imported brand cylinder is adopted to ensure good sealing performance and clear sealing lines of the bag, prevent air leakage of the sealed bag when packaging products, and reduce the scrap rate;

4. PLC control, imported driver, imported brand touch screen and man-machine interface. High degree of automation, simple operation procedure and high sensitivity of touch screen;

5. Multiple language operating system selection, according to their own requirements;

6. The external film placing mechanism is adopted to make it easier and faster to replace the packaging film;

7. Rotor pump is adopted for metering. It is a positive displacement pump. With the characteristics of low speed, high output torque and high temperature resistance, the rotor pump can play an important role in the field of conveying high viscosity and high temperature materials. Its working principle is combined with the powerful driving system. Ensure that the rotor pump can output strong driving torque at low speed, can ensure continuous and non-stop delivery of materials, and can ensure that the material performance will not be damaged in the process of delivery. The viscosity of the medium that can be delivered by this kind of pump can be as high as 1000000cp.

Maintenance of liquid packaging machine:

①: If you find that the Shanghai liquid packaging machine is abnormal when it is working, you should immediately cut off the power supply and correct the abnormality before continuing to use it.

②: Check the parts and lubrication conditions of the liquid packaging machine every shift, add lubricating oil to keep the parts lubricated, and prolong the service life, otherwise the service life will be shortened;

③: Check the end face of the horizontal heat-sealed copper block in every shift. If there is foreign matter on the surface, clean it up in time, otherwise it will cause the conductivity to decrease, the temperature of the copper block will increase, and the work of horizontal heat-sealing and cutting bags will not normal.

④: If the liquid packaging machine is not used, clean water should be used to wash away the residue in the pipeline in time to keep the pipeline clean, so as to ensure the packaging quality when it is used next time;

⑤: In winter, if the temperature is below 0°C, hot water must be used to melt the icy material in the quantitative pump and the pipeline. If it does not melt, the connecting rod may be broken and cannot be used, or the machine cannot be started.

Manually put the material into the storage hopper, the liquid filling metering device, the liquid filling meter completes the weight measurement, and then fills the target weight material into the packaging machine to seal the bag


Suitable for packaging machines of various liquids such as detergent and sauce products, rice wine, soy sauce, chili oil, jam, fruit juice, beverages, white wine, water, instant noodle seasoning water, cold skin seasoning water, vinegar, shampoo, tomato sauce, milk , Coconut milk and other products with good liquidity

Liquid packaging machine fault solutions

1. How to solve the poor sealing and water leakage of the liquid packaging machine?

      This may be because the die is not well adjusted and the pressure is not enough. Or the sealing time is too short and the sealing is not tight. Just adjust the sealing time longer.

2. The date part of the liquid packaging machine cannot be pressed out during liquid work, and it is fine if it is not turned on. What is the fault?

     For this problem, it is generally caused by insufficient air pressure, or the gas storage tank is too small, resulting in insufficient air supply. Check whether this is the cause.

3. The measuring link of the vertical automatic liquid packaging machine is to use a pneumatic liquid pump for measurement. When adjusting the weight of the vertical automatic liquid packaging machine, we need to adjust the pneumatic liquid pump to achieve the corresponding effect, but if the pneumatic liquid pump When the measurement is inaccurate, what causes it?

     Whether the model of the pneumatic liquid pump metering pump matches the metering requirements;

    Whether the metering cylinder is in place;

    Whether a check valve is installed at the inlet of liquid materials with good fluidity;

    Whether the action of the blanking cylinder matches that of the metering cylinder;

    Whether the discharge port of the pneumatic liquid pump is blocked quickly and whether there is material leakage

4. What should I do if the packaging is pleated?

      Check whether the temperature of the horizontal sealing device is too high. If the temperature is too high and wrinkles are caused, adjust the temperature and try to brush the cutting knife edge with a brush;

     Check if the packaging is caused by material clamping, if it is caused by material clamping, adjust the speed of blanking and sealing;

      See if it is caused by the pressure problem. When the horizontal sealing roller is not heated, use A4 paper to seal the sealing roller. A4 paper has a pattern display. If the pattern is different, it means that there is a problem with the pressure adjustment.
