How to use a printing slotting machine in the process of paper delivery

At present, most of the equipment at the forefront of domestic paper delivery is the way of abrasive paper delivery. When the cardboard is sent to the upper and lower paper rollers by the roller of paper delivery, the advance of the paperboard depends on the pulling force of the paper roller. Therefore, the pulling force of the paper roller must be greater than the drawing force and friction force of the paper desktop and the pressure on the top of the paper and the friction between the cardboard.

250 line ceramic reticle rolls if fitted with a hardness of 35. The rubber roll, printing dot and smaller type and line are very difficult. This is because the ink layer on the softer roll reticle rolls is thicker, but the steel roll with 180 lines is 75. The cots with higher smoothness, either in the field or in the dot, are very easy to print, because the high hardness cots are close to the scraping effect of the scraper. The importance of the rubber roll in the printing slotting machine is seen. Now we have increased the number of COTS from the original Shao's 350 + 3 to 750 + 3, and the production efficiency and the quality of printed products are also improved by the increase of the hardness of the cots. www.chinacartonmachine.com

There is no brake device in the old machine when it opens the machine. The printing department will turn with the force of the hand when opening the machine and unloading the plate, which brings inconvenience to the operation and adjustment. The mechanical transmission part of the paper feeding section has a pendulum arm. In the process of production, due to some reason (such as sorting and scraping, removing paper wool on the plate, etc.), the machine needs to be stopped. When the machine operation is opened, if the position of the arm is close to the level, it will produce a torsion because of its weight, make the transmission gear turn and cause the "wrong tooth" phenomenon. After the machine is closed again, the waste product is produced because of the deviation from the position of the printing slot, and it must be adjusted again, causing the waste of time and affecting the production efficiency. To eliminate the above phenomena, the down feed wheel and the lower pressure wheel of the printing part are used in the paper delivery part.

Although the printing department is the core of the printing slotting machine, in fact, the structure of the printing department is much simpler than the paper and the slotting department. Many people will think that the quality of the printing depends mainly on the number and quality of the reticulated roll and neglects the other factors. This includes the balance and static jump of the printing cylinder, the hardness and the middle height of the ink roller. In fact, the difference between the print of the 200 line and the 250 line reticle rolls is indistinguishable from the use of the scraper knife, so the cots play a decisive role in the uniformity of the ink and the clarity of the dots and the printing of the small words.

A cylinder is mounted on the wall of the car underneath the pulley, and two three pipe joints are used on the two pipes that lead to the lock cylinder of the car wall. In contrast to the direction of the wall lock cylinder, the trachea is attached to the installed cylinder, and the rest does not need to increase any auxiliary facilities. When the car wall lock is opened, the cylinder of the car wall is retracted, the cylinder of the brake is pulled out, the head of the cylinder head is on the shaft of the paper wheel or the lower pressure wheel. On the contrary, when the car wall is locked, the brake is automatically recovered. The hardness of the upper feeding roll binder is about 300, and some of them will be higher. As a result, the gap between the two rollers will be too large and the delivery is not accurate enough. If the clearance is too small, it will thin the paperboard and directly affect the compression resistance of the carton. The hardness of the adhesive is reduced to 20 by the paper roll. To make full use of rubber changes when taking paper, the above situation has been significantly improved.
