The use of printing slotting machine in the process of feeding paper

At present, China's most advanced paper delivery equipment for the friction feed paper, when the board by the paper roll to the upper and lower feed roll, the forward of the board depends on the upper and lower feed roll pull. 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.

Ceramic roller 250 line with a hardness of 35. The rubber roller, printing dot and smaller font and line is very difficult, this is because the rollers roller softer on the ink layer thick, but the steel roller is equipped with 180 lines on the 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. We can see the importance of rollers in printing slotting machine. We now will be made by the original machine rollers to shore 350 + 3 to 750 + 3, the production efficiency and the quality of printed products for the rubber hardness increase.

The old machine in the opening of the machine when there is no braking device, the printing department in the opening of the machine version and the release version, with the force of the hand plate rotation, to operate and adjust the inconvenience. The mechanical transmission part of the paper feeding part is provided with a swing arm. During the production process, due to some reasons, such as finishing scraping and removing the paper wool adhered to the printing plate, the machine needs to be stopped. 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 eliminate the above phenomenon, a paper feeding wheel and a printing press wheel or a pressure roller are arranged on the paper feeding part. www.chinacartonmachine.com

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 printing drum balance and static jump, ink rollers and high hardness. 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 wall is locked, the brake is automatically retracted. Paper feeding roll on the shore of the shore hardness of about 300, and some will be higher. So there will be two roller gap is too large, the delivery is not accurate enough; clearance is too small, it will be thin cardboard, a direct impact on the compression of the carton. By reducing the hardness of the upper feed roll 20. Make full use of the deformation of the paper when the rubber, so that the situation has been significantly improved.
