How to make disposable paper cups that can be seen everywhere in our lives?

Disposable paper cups can be seen everywhere in our lives, but is this so-called disposable really safe and hygienic?

First, the production of paper cups begins with this large roll of paper, and its inner wall is coated with a layer of polyethylene absorbent ink, which does not volatilize at room temperature, but may volatilize when hot water is poured into the paper cup. If this chemical substance is ingested in the body for a long time, it will cause hidden dangers to our health and even have serious cancer risk. On the other hand, the outer layer of paper can be printed with various characters or patterns as required. After the pattern printing is completed, the paper cutter will cut the paper into pieces of cardboard, and the cutting size depends on the size of the paper cup.

Second, every cut paper will eventually become a paper cup. Then they will fall neatly on the conveyor belt to form a line. At this time, the computer system will count their numbers and then divide them into 200 groups. Then they will fall to the conveyor belt below in batches, and then they will be delivered to the operator neatly. The operator will put them on another conveyor belt, and they will gradually enter the entrance of the paper cup making machine during vibration.

Third, at the same time, on the other side of the factory, a fully automatic machine is making paper cups. The machine will pull the paper into the entrance of the punching machine, and the punching machine will automatically punch the clouds at the bottom of the cup on the paper, leaving a long piece of waste paper. They will enter the recycling department of the factory through the suction device next to them. At the same time, the paper cup making machine on the other side is running fast. First of all, the mechanical gripper will put the pieces of paper on the rotating turntable one by one, and the gripper on the turntable will bend quickly and press the pieces of paper on the paper cup mold. After sealing with a hot air gun, a disposable bottomless paper cup is made.

Fourth, the next step is the most critical step. The machine will automatically push the perforated negative into the bottom of the cup, and melt the sealant at the appropriate place to seal it. The finished cup will be pushed into the chute, and the machine next to the chute will bend the edge of the paper cup into a lip to prevent the liquid from overflowing. When a plurality of paper cups are stacked together, it is more convenient for people to take them. After that, these paper cups will be pumped into the above pipes for sorting. Every pipeline here comes from a different production line. They will accurately classify paper cups of different sizes, and then put them into the counters under their jurisdiction to start counting the number of paper cups. Once the calculation is completed, these paper cups will be sent directly to the packaging department for packaging. When finished, they can wait for the final transportation.
