Why is the sandwich packaging machine essential in the commodity production process?
The food commodity market continues to prosper in our daily shopping process. Product packaging is becoming more and more diverse, especially the outer packaging of goods. For the diversification of packaging methods and commodities, as long as consumers have demand.
Food production and packaging plants can meet the market’s requirements. But these packages cannot be produced by manual operation; the mechanical process does most; these machines are sandwich packaging machines.
In the process of commodity production, many mechanical products need use, of which sandwich packaging machines are essential.
Because consumers’ demand for commodity packaging is constantly increasing, not only the manual operation standard cannot meet the standard. But more importantly, the labor cannot keep up with the market demand regarding production speed.
In terms of health and hygiene standards, there is no way for manual work to do so. Use mechanical standards. Today, the commodity market is highly competitive.
And all food packaging companies want a more efficient market to ensure quality and quantity. It can have a good development position in the market and at the same time win good economic benefits.
In the continuous development of society, the power of science and technology is constantly improving, and productivity is continually improving. Large-scale food processing plants have realized mechanized operations in all production. And sandwich packaging machines have become part of the production process. The advantage of this kind of mechanical equipment in production is irreplaceable by labor.
Why buy a sandwich packaging machine?
The sandwich packaging machine has a wide range of uses and is suitable for packaging various bagged products. It is fully functional packaging equipment. Automation technology automatically completes actions such as feeding, bag making, filling, sealing, weighing, coding, and conveying.
The intelligent sandwich packaging machine was independently developed and produced by Sanlin. It can start vacuum feeding, automatic dosing, automatic bagging, and finished product conveying.
The sandwich packaging machine adopts Omron PLC program control, touch screen man-machine interface, servo system drive, and photoelectric automatic detection. And tracking, analog input module to control temperature control system, frequency conversion adjustment for dust collection, and so on. It can make the whole machine’s operation both intelligent and straightforward and improve the production efficiency of the food packaging industry. It can reduce workforce and material resources and is the vertical packaging equipment sought by various enterprises.
What is the measurement method of the sandwich packaging machine?
- Combination scale
The weighing measurement of the combination scale is to weigh and unload the material by combining multiple scales. The combination scale includes 8-head scales, 10-head scales, 12-head scales, 14-head scales, 16-head scales, 24-head scales, and even more. Many intelligent weighing and measurement accuracies are also high. The price of the combination scale is the more expensive of the four types of measurement.
- Screw scale
Screw scales are mainly suitable for materials that are not easy to vibrate or easy to accumulate. Such as milk powder, coffee, tea powder, and other more delicate fabrics are weighed and measured.
- Measuring cup
The measuring cup is mainly needed to measure by volume. First, weigh the material, then pour the material into the measuring cup and set the capacity of the measuring cup. This measuring cup needs to use for measuring the precision of granular products. It is generally suitable for packaging bulk materials, and the price of this kind is lower.
- Linear scale
The principle of weighing with linear scales is similar to that of balance scales. Linear scale weighing measurement is mainly suitable for packaging large-weight rice and other materials of the following size.
How to choose a sandwich packaging machine?
For each enterprise, a sandwich packaging machine is an essential tool for product packaging. The packaging machine’s quality will affect product packaging’s quality and efficiency. We must not ignore it. But if we want a sandwich packaging machine, we must make more effort when purchasing and distinguish carefully.
The purchase of sandwich packaging machines is also a profound knowledge. But a superficial understanding is far from enough; we need to accumulate and learn more in peacetime. So, what principles do we need to follow when choosing a sandwich packaging machine?
- The machine must meet the product packaging process requirements and adapt well to the materials. And containers selected for the product ensure the packaging quality and production efficiency. The requirements are advanced technology, stable and reliable work, and convenient use and maintenance.
- Pay attention to the versatility of machinery and can adapt to the packaging needs of various types of products.
- Reasonable control of the conditions required for product packaging, such as temperature, measurement, speed, etc., to ensure the packaging effect.
How does a sandwich packaging machine work?
sandwich packaging machines need to use in vertical packaging machines in various industries. And can be used to convey powder, granular and small materials level or obliquely.
The sandwich packaging machine has a simple structure, small cross-sectional size, good sealing performance, and reliable operation. And it is convenient for middle loading and unloading. The materials can also be stirred, mixed, heated, and cooled during the feeding process.
The working principle of the sandwich packaging machine can divide into the following three types:
Gravity slide method. The rotation speed of the screw is low. And the material on the screw surface is affected by gravity far more than centrifugal force. The screw machine belongs to this principle.
Because the rotating material of the screw continuously slides down the screw surface, resulting in axial displacement.
The filling factor value of the screw machine of this principle is generally less than 0.5. Because of too much filling, the material does not slide down the helical surface.
And the spiral agitation makes the material fall over the winding shaft. A sizeable axial speed needs to obtain. It cannot be used for vertical helical or upward conveying with a large inclination angle.
Push method. The pushing method needs to use for unloading and conveying at the bottom of the silo. The material is often necessary to fill with the screw, and the static pressure of the granular material is relatively large. The resistance of this kind of spiral is considerable.
Centrifugal induction. It needs to use for vertical screw conveyors with steep inclination or any screw conveyors with high rotation speed. The effect is far more significant than the influence of other external forces such as gravity.
Let’s take a look at the operation method of the sandwich packaging machine:
- We turn on the machine’s leading power and seal the shaft vertically and level. And preheat the date printer to the set temperature.
- We check whether the date ribbon, packaging film, and electric eye are needed to install correctly.
- Turn on the date printing switch, send the packaging film to the predetermined position, and start the motor. And stop the inspection after 4 or 5 empty bags need production.
And then the unloading switch needs to turn on to work.
- Turn off the feeding switch before shutting down, and turn off the motor’s power.

In recent years, with the rapid development of food and other industries. The sandwich packaging machine market maintains rapid growth, basic technology, and innovation. And service capabilities of domestic sandwich packaging machines have been continuously improved and are gradually favored by more fields.
The sandwich packaging machine has an automatic quantitative function. It can perform quantitative production according to user needs to meet customers’ needs for large-scale production. However, during the actual operation of the sandwich packaging machine, some faults may occur, as follows:
startup problem
When using the sandwich packaging machine, it is found that the automatic program cannot start suddenly. Then first check whether the discharge cylinder is closed and the position sensor is loose. And in place when the cylinder is closed.
If the sensor position is incorrect, the magnetism of the permanent magnet in the cylinder will weaken. It causes the signal to run out of control. The automatic program does not start if the sensor position cannot adjust, shorting the sensor output wire.
monitor problem
The weighing accuracy of the sandwich packaging machine is very important. But the display value of the weight display of the packaging machine is unstable. In this case, it is generally necessary to eliminate the vibration phenomenon of the food quantitative packaging machine.
And check whether the voltage is stable, whether the grounding resistance of the fuselage meets the requirements, etc. And keeping the display value stable.
Seriously out of tolerance
During the use of the sandwich packaging machine, it is found that the unloading weight is unstable and out of tolerance. It is necessary to check whether the oil circuit is blocked.
When the oil circuit is blocked, the cylinder sealing gasket and body will be damaged due to dry grinding. It will cause air leakage and affect the feed stroke of the cylinders at all levels.”In this case, the two-stage rubber gasket of the main cylinder can replace and Also clean the oil circuit.”
Hopper leaking material
The material leakage from the hopper is directly related to the failure of the discharging mechanism. It is necessary to remove the accumulated material in the hopper first and observe whether the discharging cylinder is in place.
The bag clamping mechanism does not work.
The electrical switching valve is not working properly if the bag clamping mechanism does not act. If the electrical conversion is normal, the reversing valve is faulty. The valve control triode and bidirectional trigger photocoupler should be replaced in time.
The above are several common problems in the use of sandwich packaging machines. Only based on understanding the overall structure of the equipment and correctly installing the equipment. And mastering the relevant problems and solutions can the user ensure the equipment runs better and stably.
