Can pressing is a process during which a strong pressure is applied to the can and due to the applied pressure, its shape changes or in other words the can is crushed.
Can pressing is one of the most important steps in recycling operations. Recycling of waste and especially metals saves the consumption of natural resources; Because recycled materials can be used to produce new products. Another benefit of metal recycling is energy saving, in addition to not needing a large space for landfilling.
It is said that the energy required to make metals from recycled metals is about 90% less than the energy required to extract metals from minerals.
One of the most expensive parts of the recycling industry is waste transportation. Therefore, it can be said that reducing the amount of waste is necessary in order to reduce the costs of recycling. Pressing cans as a way to reduce the volume of waste for recycling will be an effective and useful method.
The can press machine is a tool used to press empty aluminum cans for easier recycling. Using this device in industrial businesses or restaurants, in addition to adding to their smart appearance and providing a great contribution to the recycling industry, can be a very good source of income for the owners of these businesses.
It seems that the can press machine is useful and practical only for industrial businesses that deal with aluminum cans or restaurants that send a significant number of aluminum cans to the trash every day.
But if a family’s daily shopping basket includes cans or soda cans, they can use can press machines that are made for home use. Using a can press machine at home prevents taking up a lot of trash space. Besides helping the environment with the recycling process, it helps to increase the family’s income.
Necessary cost to buy a can press machine
Although the initial cost of buying a can press machine may seem expensive, the long-term benefits, such as having a clean work environment and the income from selling scraps for recycling, will justify the cost.
Aluminum can press machines have different prices according to their weight and application. The basic price of a waste press machine and aluminum cans for an industrial environment starts from 30 million Tomans, and with the increase in the weight of the machine, its size and the capacity of the machine, its price increases.
The cost of buying a manual can press machine, which is suitable for home use, is nearly 2 million Tomans, which seems to be a reasonable price considering its long-term profitability for families.
Description of can press machine parts and how they work
The can press machine is one of the most used machines in the recycling industry. The mechanism of this device as well as its design, contrary to what it seems, is not simple.
The main task of the can press machine is to fully compress the cans, or in other words, crumple them in the best possible way; So that the cans are ready to be transported with the smallest possible volume. To achieve such a goal, a strong and solid structure is needed, as well as high power for the machine jack.
During the pressing of cans, very high pressure is applied to the body of the pressing machine or actually its chassis. As a result, the structure of the can press machine must be made in such a way that it has enough strength to withstand the high pressure applied. Usually, the chassis of the can press machine is vertical.
In fact, the chassis is placed in the form of a port in the device, and other components of the press are connected to the chassis by means of a pipe. The way the vertical can press machine works is that its doors are closed from both sides; Then the cans ready for pressing are poured into the machine.
After several rounds of movement of the machine, which is required to press the cans, the cans reach the minimum required dimensions and then the pressed cans are packed. At the end, the two doors on the side of the machine are opened and the packed cans are removed from the machine and ready to be transported.
One of the disadvantages of this type of press is caused by the pressure of the anvil. The pressure of the anvil, after some time, causes problems in the structure of the can press machine, which must be considered.
However, the design of the press is such that there is no need for ejector levers (ejector jacks) in its structure. This type of structure will reduce the production cost of the can press machine and, as a result, reduce the total price of the machine for the buyer.
To solve the problem in the structure of the can press machine caused by the pressure of the anvil, the designers have proposed another model for making the machine. In this design, the press is made like a closet. The thickness of the iron wall of these cupboards will be 2 cm and in some parts 4 cm. Therefore, structural problems caused by anvil pressure will not exist in this model of can press machine.
Another main part of the can press machine is its main jack or vertical jack. The power level of the main jack of the device is very important. The power of the jack of the device has a direct relationship with the diameter of the jack. That is, the larger the diameter of the jack, the greater the pressure exerted by it, and as a result, the pressing power of the device increases.
As mentioned, ejector jacks are also part of the can press machine. After pressing and compressing the cans inside the machine, the pressed cans are wired.
Due to the high pressure of the jack, the pressed cans are pressed against the inner wall of the press. In this case, taking out the pressed package is not easy and requires a lot of force. At this stage, using jacks or ejector levers, we remove the final pressed package from the machine.
The way this device works is that first the packaging wires are passed through the grooves on the bottom of the press. In the next step, the empty cans are poured into the machine to be pressed by means of a loading funnel, manually or by a conveyor belt.
Then, by pulling the vertical jack, the pressure of the lowered anvil causes the cans inside the machine to crumple. This movement is repeated many times until the dimensions required for the pressed package are reached. Finally, in the same state as the pressure of the anvil on the cans, the other end of the wire is passed between the grooves of the anvil and the package is wired as tightly as possible.
The vertical jack moves in the opposite direction and returns to its original position. Pressed cans are removed from the machine by ejector jacks.
How to make and produce a can press machine
The structure of the can vertical press machine is designed and built like a closet. First, the chassis of the machine is made in the form of a closet and by iron sheets with a thickness of 2 and 4 cm.
Studs are placed on the bottom of the device so that the wire required for wiring the final package passes through the grooves of the studs on the bottom of the device. In this way, by adding other parts mentioned in the previous part to the chassis of the machine, the can press machine is made.
The stronger the structure of the press machine and the power and power of its vertical jack, the more efficient it will be and in the long run it will have many benefits for its users.
