Recycling and recycling of cutting waste
in the process of printing production, some people can only see the waste and garbage generated after paper cutting, while others can see the value behind these wastes. If an industry always pays too much attention to the import and export of each sum of money, it may lose the opportunity to turn waste into treasure
when printing houses are thinking about making money all day and buying large-scale equipment from printing machine manufacturers such as Heidelberg, gaobao and Manroland, there are also some manufacturers, such as G.F. Puhl, Vecoplan, Ohio blow pipe, air systems and design and Bello, although they are not as famous as other companies, But they can bring higher return on investment to those printing plants that use Komori and Mitsubishi printing machines
recycling and selling these wastes is very tempting for printing enterprises that often produce large quantities of production wastes. Quad printing company in Sussex, UK, is particularly in line with the above situation - if a printing factory can fill the whole waste box with waste paper, it can earn at least $1.8 billion a year. According to pat rock, the waste recycling director of quad printing factory, Quad can produce about 1500 tons of printing and post press processing waste every month, not including the loss and waste white paper in the process of book post processing. On the whole, the company produces about 4500 tons of waste every month
with the increase of business volume and the gradual aging of paper recycling system, Quad printing company decided to establish a new large-scale waste recycling system. So the largest private commercial printing plant in North America asked G.F. Puhl to help it design and install a cutting waste collection system that is said to be the largest in Britain. The company installed seven 45 inch high cyclones in its 15000 square foot plant. Each cyclone can reach a speed of 50000 cubic feet per minute, which is enough to buy a hot-air balloon in less than two minutes, and then it can be used directly and conveniently. In addition, they also installed four new high-capacity automatic Baling Machines and conveyor belts, as well as a cutting waste collection system with a two meter long pipe
when determining how large a recycling system the factory needs, Quad measured the speed of the packer and the amount of waste generated. Rock said, "we always want to have a spare production line. In this way, when we maintain the equipment, we don't have to turn off the binding machine, riding stapler, mail group machine or paper cutter. They can achieve continuous normal production, and we can continue to maintain the equipment."The size of the recovery system depends on a complex formula, which is mainly related to the volume of air and the output of waste. Quad printing chose a packer that was faster than they needed because they wanted the packer to run at a lower speed than the maximum speed. The material has a certain plastic capacity
although these systems are assembled by established manufacturers, and their huge cyclone device can also give people a strong shock, the printing factory can still control the cutting waste recycling system through the web browser. Rock pointed out that operators can adjust the functions of the recycling system through the touch screen, and Quad has also equipped a larger control system for this system
let's have a brief understanding of the work of the cutting waste recycling system. When the waste comes out of a printing and processing line with the product, its speed is about 85 meters/hour (7500 feet/minute), and then the pipe conveying the waste will turn to the horizontal direction and maintain a low speed (68 meters/hour) until they are sent to the top of the pneumatic device. At this time, these waste papers will suddenly slow down and fall freely at the speed of 3 meters/hour, and finally reach the bottom of the tension test clamping device of the cyclone device at any position
the cyclone device can separate the cutting waste from the dusty air, then compress the paper into 1500 pound pieces, and discharge the filtered air into the factory or outdoors. The compressed paper can be sent to the factory that produces toilet paper, and can also be remanufactured into exquisite writing paper or cover paper
rock pointed out that the printing factory needs to spend about three months to train new employees using this system, especially to be extra careful about the handling of paper packers - many people think that packers are the most dangerous machines in the printing industry. Because it has multiple converter valves and blower devices, blockage is the most common operation problem, and it is the most critical problem. In quad printing plants, congestion problems can always be found as soon as possible because they have advanced inspection and balancing systems
worry free operation
the ease of use of the system is the most attractive. Rock said: "For an operator, the best feeling is to be able to master everything and have all the necessary knowledge. The chart of the waste recycling system can accurately tell you the progress of your work. If there is a problem, the system will not only tell you where the problem is, but also tell you how to solve the problem and who to turn to when you can't solve it by yourself."
rock is unwilling to disclose information related to the return on investment or cost, but he made it clear that quad is very satisfied with the performance of this recycling system so far
he said, "the most important thing we do is to install the best equipment in the market for the factory, so that our core business - printing and binding product catalogs and magazines - can maintain normal operation."Publishers printing recently installed a new waste recycling system in its plant at the Lebanon junction, which opened in June 2005 and closed in March this year. During the nine months of its normal operation, two-thirds of the roof of the packaging workshop will be replaced and will be increased by 20 feet
according to John Hardin, the warehouse administrator of the company, this recycling system with two cyclones takes up about 5000 square feet of space, and it is also equipped with a dust collector. This recycling system replaces the company's original system with similar functions, but slightly inferior in size and ease of use. Whenever employees change shifts, they have to close the old system and replace the dust collection bucket, while the new system requires an air lock to achieve uninterrupted production
publishers printing can produce an average of 2.2 million pounds of packaged recycled paper per month. Hardin pointed out that G.F. Puhl, which designed the system, fully considered the current and future needs of the company when determining the size of the cutting waste recycling system
another advantage of this system is that it can be connected with the service technicians through the line. As long as there is a problem, the technicians can easily find the root of the problem and solve it as soon as possible
prepare for the future
hardin points out: "The working efficiency of this system is very high, and it can bring people a cleaner working environment. Of course, with the help of rg42 plx/60 Vecoplan shredder, we can easily dispose of the waste generated in the printing and binding workshop. We know that we need to comprehensively update the waste collection system, and we are also doing so. By installing a new recycling system, publishers printing company has provided Waste and dust collection needs to be prepared. "
not all systems can achieve the ideal recovery effect, and don't try to calculate the specific figure of the return on investment. Bedford produces about 100000 pounds of cutting waste every month. Before the recycling system was installed in the summer of 2005, the waste paper produced by the paper cutter and the horse stapler would be thrown into a huge Gaylord waste carton. When these boxes are filled, the machine will stop running, and people will load these untreated waste cartons into trucks and transport them to recycling companies
in fact, recycled paper can bring shocking benefits to printing enterprises. Franz beisser, one of the main principals of Bedford company, pointed out: "if you can make good use of these wastes instead of discarding them, you are likely to earn more income - perhaps twice the previous income. In addition, if you don't have a truck with a particularly strong loading capacity, recycling waste can also save you a lot of freight."
he said, "when calculating the return on investment, I hope to help you further understand this equipment. The only problem we face is that we can't calculate the number of waste pages. They are changing at any time. We don't know how many waste pages will be generated in the next six months, and we can't even predict the waste output in the next month or two."
the system installed by air systems and design covers an area of 400 square feet. Due to its small size, this system is composed of a 40 horsepower engine fan, rather than a cyclone device. Balers and air filters are placed around the systemThe main reason why bison printing company wants to introduce this new system is that its wireless binding machine and old-fashioned cyclone device can no longer meet the production requirements. The new system has brought them amazing results, and this system does not need enterprises to spend a lot of money on maintenance and repair. In addition, the probability of blocking failure is also very small
in addition to the waste paper that can bring people a higher return on investment, the new recycling system (especially the system equipped with air filtration device) can also save users a lot of heating and cooling costs. In the old system, there is no filtering device, so bison company is required to reheat or cool the air, resulting in a waste of energy costs
in the end, waste recycling can win you higher productivity and more money - no matter how small the waste is - this is the most important point
beisser said, "we used to need to constantly empty and transfer a large number of waste bins. This is a big deal, because if you fill many bins with waste every day, they will always be full, and operators will be more prone to make mistakes. Now, we don't need to do this. This new waste recycling system can keep us working normally for a long time without any mistakes." (end)
