UPS for PP bag production line

3rd, April 2021

UPS or UPS, short for Uninterruptible Power Supply It is a break. This electronic tool supplies the electric current needed by the consumer’s electrical appliances during a power cut and in this regard, after establishing the reflow of municipal electricity is responsible for regulating and maintaining the electricity grid; In addition, this device prevents the penetration of noise and disturbances in sensitive consumer equipment.

Among the influencing factors during UPS powering, the following can be mentioned:

Number of systems and amount of load connected to the UPS

Capacity of the battery used in the UPS input

UPS working method

Also check: Which UPS is suitable for CCTV?

Among the duties of UPS and how UPS works, the following can be mentioned:

adjusting and modifying showing or increasing and decreasing output and input voltages, with the aim of providing an acceptable voltage for the device

Providing the electricity needed by the consumer equipment with the desired quality and continuously

All this happens when the regional electricity supplier has general or partial problems.

The types of these electronic tools are:

Offline UPS

On line UPS

UPS Interactive or Line Interactive UPS

This type of UPS is activated during a power cut in the circuit.

One of the most common fields of use of UPS is in polypropylene bag production lines. In the rest of this article, we intend to introduce these production lines to better understand the importance of using UPS in these lines.

Introducing the polypropylene bag production line PP

Polypropylene bags have high resistance while being light; For this reason, they are among the most cost-effective categories for food. Polypropylene bags with a high standard satisfy the needs of most factories and industries.

Polypropylene bags are produced and marketed in four main stages. These 4 steps are:
– The spinning stage
– The weaving stage
– printing, cutting and sewing stage
– Packaging

Spinning stage

In the spinning stage, the following actions take place:
– Mixing granule and paint
– melting granules in the extruder and at a temperature of 250 degrees Celsius
– cooling the film coming out of the extruder using a water pan or a water roller at a temperature of 30 degrees Celsius
– first and second stretching with the aim of flattening the produced film
– longitudinal cutting of the film to the required dimensions according to existing standards
– Grinding the extra edges of the film and returning it to the extruder
– Heat with the aim of stretching the tape at a temperature of 160 degrees Celsius
–Third stretch (final) and changing the tape dimensions
– Heating the back and on the tape produced at a temperature of 140 degrees Celsius
– Cooling the tape to stabilize the molecule at a temperature of 10 degrees Celsius
– winding the tape on the bobbin for using round weaving machines

Weaving stage

In the weaving stage, the following actions are performed:
– Weaving tape by weaving machine
– PP roll sack production
In the weaving sector to produce fabric, there are often three main methods which are:
1- Weaving Tari and Pudi
2- Circular weaving
3- Weaving Pudi ring
In this design, warp and weft weaving is recommended with a warp knitting machine. production bags with the ring method for packing and transporting materials that have coarse more grain size It is desirable. According to the type of sack consumption, it is necessary to choose one of two methods for production.

Cutting and sewing

At this stage, the sack roll is placed in the initial cutting line and is cut according to the requested length by the heat blade. The process of sewing the bottom of the sack is folded to the desired size and crocheted by a special sewing machine.
Packaging
After counting 500 sacks, the sacks are manually or press baled and sold to the market.
