 How to use the printing slotting machine in the process of delivering paper

At present, most of the domestic paper feeding equipment is the friction feeding method. When the paperboard is sent from the paper feeding roller to the upper and lower paper feeding rollers, the advance of the paperboard depends on the pulling force of the upper and lower feeding rolls. So the feed roller tension must be greater than the paper feeding suction force and desktop friction force and the pressure above a stack of paper and cardboard between the friction force, it can only accurately; the cardboard to the printing department, the general equipment used on paper feeding roller core plastic bags, lower feed rollers for chrome knurling steel roller. www.chinacartonmachine.com

250 line ceramic anilox roller, if match hardness 35. The rubber roller, printing dot and small fonts and lines are very difficult, because the softer roller top roller has a thicker ink layer, but the 180 wire steel roller has a hardness of 75. And finish high rollers, whether on-site printing or fine print outlets are very easy, because the high hardness of the rollers is close to scraping knife scraping effect. This shows the importance of cots in printing slotting machines. We have now made part of China's domestic cots from Shao Shao 350 + 3 to 750 + 3, the production efficiency and quality of printed products also increased due to the roller hardness.

When the old machine opens the machine, each part does not have the brake device, when the printing department opens the machine to install the version and to unload the plate, can move along with the board hand's force, brings the inconvenience to the operation and the adjustment. The mechanical transmission part of the feeding section has a swing arm, and in the production process, for some reason (such as finishing, scraping, removing the paper, hair stuck on a printing plate, etc.), the machine needs to stop. Open the machine operation, if the position of the swing arm is close to the level, due to its own weight will produce a torque of the drive gears to rotate, resulting in "the wrong tooth" phenomenon, again machine, because of the deviation and position and printing waste, but also must be re adjusted, cause a waste of time, affecting the production efficiency. In order to prevent the above-mentioned phenomenon, the lower delivery wheel and the printing press wheel or the pressure wheel or the press wheel of the paper feeding unit are used.

Although the printing department is the core of printing slotting machine, but in fact the printing department structure relative to the paper feeding part and slot much simpler, many people will think the quality of printing, mainly depends on the number of roller and quality, while ignoring 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, without the use of scraping knife equipment, printing the difference between 200 line roller and 250 lines are printed, with visual sense are indistinguishable, so it plays a decisive role in cots and uniformity of outlets and fine print ink for clarity.

The installation of a cylinder wall of the car beneath the wheel on the drop down, leading to the car in the two pipe wall of the lock cylinder with two three vent pipe joints, and the wall of the car lock cylinder in the opposite direction will be installed in pipe is connected with the cylinder, the other does not need to add any auxiliary facilities. When you open the car lock wall, (due to different direction), the back wall of the lock cylinder car, brake cylinder type, cylinder head in the wheel or under pressure drop round shaft (shaft thin can add a knurled collar to brake). On the contrary, when the car wall is locked, the brake will automatically retract. The top of the paper feeding roller is about 300 in hardness and some higher. In this way there will be two roller gap is too large to send accurate enough; gap is too small, and will compress cardboard, directly affect the carton pressure. Reduce the hardness of the top roller by reducing it to 20. Taking full advantage of the change of rubber when taking paper, the present situation is obviously improved.
