For an automatic horizontal wrapping machine, the conveyors can be an essential part. Because without the conveyors, the machine needs many workers to associate. When the conveyors are power by the motors and controlled by PLC and converters, it can run automatic and workers just need to put the goods on the conveyors manually or by forklift. The sensors can detect the goods when they arrive at certain points. So, no more heavy work load and physic work, it just all take over by the machine itself.
But choosing and making the machine can be difficult. First, there are mainly four types conveyor, the roll type, the belt type, the chain type and the chain board type. Each has their own character, for instance the roll type are capable to bear heavy weight and the belt type is cheap and convenient and protective but can not bear good with very heavy weight. When you need to choose a type of conveyor, you really need to look at your products and decide which can be the best choice for you.
Difficulties also appears when make the conveyor. First, the material. It needs to be strong enough to bear the load and friction. Second, parallelism is really hard to control and the conveyors are easy to lean to one side.

In the ancient time, no matter a country or a person would constantly advance themselves with the newest skills and sharpest weapons. Because of the harsh living environment and fierce competition between tribes and individuals, they had to keep themselves on the top at their age.
Back to today’s world, thing has changed a lot. The big environment has been improved dramatically and people are tend to behave in a civilized manner. But competition still remains. And this time it’s not just between individuals or countries, it’s more between companies. Without constantly studying and keep accepting new things, a man can be abandoned by the era. Without the advanced technology and machinery, a company also can be losing behind. That’s what we call self renewal.
In the mechanical industry, we see many companies still remain on the way they do their business. Old workmanship, old machinery, old sales format. Some of them even still rely on cheap labor and manual work. They need to change themselves otherwise the market will change them by the way of eliminating them.
Just like the great naturalist Darwin said, the survival belongs to the most adaptive ones, the market is also always belong to the ones who are constantly doing their self renewal.
During the pallet wrapping, the stretch film goes through two different forces by a wrapper: stretch and pre-stretch. The stretch occurs when the film is placed around the pallet, so that a sufficient tension in order to contain the palletised load is achieved. However, there is also another method to optimise the quantity of stretch film on the cargo: the pre-stretch. This system tightens the stretch film (achieved with an electronic motorized pre-stretch carriage) and optimises the necessary quantity of stretch film in order to wrap the pallet, stabilising the load.
In automatic wrappers, the pre-stretch carriage takes the film through rubber coated rollers. These are connected by a system of motorized transmission that generates different rotation speeds of the rollers. The film is then stretched between them and extended for the quantity equal to the difference of rotation speed between the rollers. At this point, the film is released on the cargo.
However, how much is the stretch film pre-stretched? This depends on every machine, because each wrapper is created in order to pre-stretch the film until a certain point. The percentages go from 150% to 300%, which is always more common nowadays thanks to high technology wrappers.
In the end, we can say that the pre-stretch of stretch film allows concrete and sure savings in terms of money. The extension of film ensures a lesser amount of material to efficiently wrap the pallet and to stabilise the load.
The world has been developing fast in the last century, we human beings experienced from the second industrial revolution to the third industrial revolution. Machinery has replaced labor in mass production and made products become cheaper.
It all seems that pros are always more than cons. But actually those changes has set a test on companies who are in the fierce competitions. Yes, all the changes may bring opportunities but also bring challenges to us. In the market, companies who do not have strategy and less competitive will surely be eliminated.
As we are in the packaging industry, we found it’s really important to keep on investing and studying on new technology and conception. We need to be flexible, and not just in the way we work but also in the way we make our products. So many people talked with me about their experience, it’s seems they can’t find the right machine they want despite the fact that inflation has appeared in the market already. Why does this happen? The reason is we always want to do things in a simple way, to copy others, to follow the trend, to be alike with others. What we forgot is what does customer really need, their special requirement.
