Flow wrap machine is a kind of continuous packaging machine, which has strong ability and is suitable for various specifications of food and non-food packaging. Due to the tension of packaging material and other factors, the predetermined sealing part of the material may deviate from the correct position and cause errors. In order to eliminate errors and achieve the purpose of correct sealing, the design of flow wrap machine must consider the problem of automatic positioning, which is mainly solved by designing a continuous photoelectric positioning system to allow other transmission mechanisms to maintain synchronous variables. On the other hand, the old synchronous wheels and frequency conversion flow pack machines rely on continuous debugging and adjustment, which requires constant change of parameter variables, complex operation and delayed efficiency. But the new full servo control flow wrap machine has no problems in these aspects at all.
Fully Servo Control Flow Wrap Shrink Packing Machine
Characteristics of Servo Flow Wrap Machine
1.The use of grating detection photoelectric eyes, compared with the traditional point-to-point photoelectric, it can detect irregular products such as vegetables, fruits and so on in a larger range, so as to ensure that the distance between products can be controlled at the front end of the transmission line to ensure the later work process.
2. All movements are controlled by servo motors with encoders, such as conveying, feeding, sealing and cutting, etc. Together, instructions issued by CPU can make them work synchronously, because the operator does not need to master adjustment experience, only need to input the necessary packaging size and speed, the efficiency is greatly improved and the work is stable.
3. Servo flow wrap machine uses an integrated motion unit control system instead of a traditional PLC plus display, so it can more easily display the operating parameters and the status of each system on the control panel, and can feedback the corresponding parts in case of machine failure, so that the operator can deal with it.
4. It can be equipped with color film positioning function, and the use of color printing film can save the cost of purchasing additional printing materials.
The structure of Servo Flow Wrap Machine
What are the advantages of servo control one compare to other traditional type?
1.Servo flow wrap machine packaging bags can be very long (no specific restrictions, 3000-5000mm can be), but usually frequency conversion control equipment is usually only 200-400mm.
2.The function is very user-friendly, automatic positioning, without the need for staff fixed-point feeding, greatly accelerate the release speed (double frequency conversion must be in accordance with the feeding hook to release, the speed is fast, the eyes of employees may be unbearable, the speed is very dependent on skilled workers).
3. On the servo flow wrap machine, if there is a product on the conveying line, the film will go. If there is no product on the conveying line, the film will not go, so the air-proof bag can be achieved and there is no more empty bag to waste.(the feeding speed of the double frequency conversion structure is synchronized with the film feeding speed, once there is a position where the product is not put, the empty bag will be out of the empty bag, and the counting function empty bag will also be counted, so once the speed is fast, the probability of empty bag is very high.)
At last, due to the popularity of servo motor technology, the cost of servo pillow is no longer so expensive, compared with their more advantages, higher efficiency, simpler setup and operation; slightly higher cost is nothing. Now more and more users prefer to use full servo control pillow machines. If you have more questions about related equipment, you can consult the professional sales engineer of SNCPACK.
