How to install the printing press scientifically and reasonably and be familiar with the trial operation of the machine is an important part of improving the machine performance and service life.
First, a number of factors that should be taken into account when determining the installation position of a printer.
1. The characteristics of the printing machine operation and the requirements of the machine operating characteristics and requirements are the basis for determining the location of the printing machine.
In addition to taking into account its own volume, the space occupied by a printing press should fully take into account the space required for operations, as well as the active position of the paper holder, the placement of ink sheets and semi-finished products, and the activities required for overhaul of the machine. Space and so on. Under normal circumstances, if you need at least 60cm of space when operating, you should place the machine in an 80cm space. In areas requiring strabismus or bow-back operation, there should be at least 1m of space above the movable space. If ink is added to the ink pool, it can be placed at an interval of 80cm, and the space where the piled paper position and the delivery position need to work should be at least 1m above the room. All parts of the machine operation surface should have a space of at least 1m.
2. The printers that do not affect the same model when the adjacent machines are operated should be placed side by side and have the same floor area. Adjacent display must be neat and beautiful, but also better use of space. The spacing between adjacent machines, in addition to taking into account the space required for operation, should also consider that when one side performs equipment adjustments or repairs, it should not affect the normal operation of adjacent machines, in particular, the operational safety is not threatened. In practice, due to the excessive use of "space" in the initial stage of equipment installation, the space between adjacent devices only considers the normal operating space. As a result, the narrow space causes another machine adjacent to a repair machine to temporarily shut down. repair".
3, the location of the paper and semi-finished products piled up due to the different production performance of the printer, the print structure and product batches are also different. Equipment for printing color products sometimes needs to use paper holders to dry semi-finished products. Therefore, it is necessary to fully consider the drying cycle of drying and the racks of printing products, and occupy the space around the machine. Both of them need to print sleeves and overprint products at the same time. The machine platform, as far as possible not to be placed adjacent to the name of the two machines at the same time when the use of paper holders lack of space to affect the normal production.
4. Minimize "dead zones"
When installing a printer, consider minimizing the "dead zone" and increasing the space utilization of the site. The machine's operation surface and transmission surface space should not be equal, the drive surface generally does not stack paper and semi-finished products, the active space should be smaller than the operating surface, the drive space is left blank for lubrication, adjustment and repair of the required spacing is to avoid causing "dead space" waste Space is available.
The location method of the printers is also different due to different plant conditions, such as the area of ​​the plant and the placement of the machines, the number of units, and the different positions of the walls, columns, doors and windows.
Second, scientific and rational installation of printer stands is a guarantee of reliable operation of the equipment.
How a printer stand is mounted not only directly affects the quality of the product, but also affects the life of the device.
1, must, firmly press the base of the printer base.
If the foundation is not strong enough, even if horizontal adjustments have been carefully made when the machine is installed, after a certain period of operation, the basic level will also fluctuate due to oscillation damage. This will cause the machine to deflect and cause unstable operation. problem. Therefore, any printing machine with a weight greater than 1T must consider installing a foundation. The printer less than 1T does not need special consideration, but it can not be placed casually, and must be placed in a flatter, firmer position. In addition to considering the weight of the printing press itself, Zakijiki must also take into account the dynamic load transmitted to the foundation when the machine is in operation and the level of softness and hardness of the shop floor. If the workshop is built on the field, the geology is soft, the foundation should be deeper, and the area should be appropriately expanded to prevent deformation under the stand.
2. Calculation and construction method of foundation If the geology of the production workshop is soft, the printing machine should dig deeper, that is, dig 23 meters deep from the ground, fill in the pebbles and sand, fill in the above After pouring on the concrete and smoothing the surface, it can be done. The foundation of the printing machine base is sufficient for its strength of 3T/m meters. The area of ​​the foundation can be slightly larger than the area of ​​the bottom of the printer.
When calculating the pressure of the printing machine on the ground, the total weight of the machine should be divided by the bottom area of ​​the machine. The calculated value is only the static pressure of the printing press to the foundation. Since the foundation will also generate shock vibration when the machine is running, the calculated data should be increased by about 20% to determine the pressure of the foundation.
3, the installation of the machine on the machine seat should pay attention to matters should be completely dry after printing the foundation can be moved to the machine base for installation and commissioning. Installation and commissioning is a meticulous task. Before and after, left and right, vertical and horizontal parts of the machine, it is necessary to adjust the balance with the level meter repeatedly to make the whole machine in a horizontal state. The padding used at the bottom of the machine must use iron plates with good compressive strength so that the base can be as tight and uniform as possible, without leaving a large-area, “floating†condition to prevent deformation under pressure. After the machine is calibrated horizontally, it is necessary to apply a good base screw, and each time the screw is subjected to a uniform force. If the force is uneven, the horizontal state of the machine is easily damaged. After the installation of the machine after a few weeks or months of operation, should be re-check the level of its state, or the current deflection should be relatively flat in time to prevent machine deflection and lead to component wear and reduce the accuracy of the equipment.
Third, the printing machine should pay attention to the trial operation issues 1, the preparatory work to do a good job before the trial operation of the machine is an important work, before this detailed and serious inspection and cleaning of the machine: Printing machine Whether the parts of each part are intact, screws, nuts, pins are good; whether the gear box, oil hole and other parts of the ink meet the requirements of the manual; after manual rotation of the machine for a few turns, see whether the various parts of the jam Phenomenon; whether the on-board safety interlocking device and the micro-motion range switch are reliable and sensitive; whether the gas system is normal or not. In addition, the debris around the machine must also be fully cleaned and finally powered on.
2. Working essentials during test operation When the machine has been manually operated for several weeks, after confirming that there is no abnormal condition, the machine can be operated for several weeks with low-speed jogging, and observe whether the operation of each component is normal or not. Blocking phenomenon and abnormal sound, then you can run the test at low speed. In the meantime, attention should be paid to the abnormality of the sound and lubrication conditions; whether there is excessive temperature rise in the rotating shaft parts; whether the dynamic braking is sensitive and reliable; and whether there is any abnormality in the shift from the lost motion to the combined pressure operation. After several hours of continuous test run from low-speed operation to high-speed pressure-compression operation, the moving parts of the machine are run in, eliminating some burrs on the parts and reducing the resistance of the machine during operation. During the test run, check the working conditions of the paper feeding components. Check whether the feeding time of the paper feeding device, the rules, the paper feed teeth, and the roller teether is accurate. Check if the suction and air blowing on the air pump and the printing machine are appropriate. Whether double-sheet or air-sheet control is sensitive, if there is something abnormal, it should be adjusted and handled in time.
3. Conduct printing test to master the work performance and characteristics of the printer. The trial printing work is an important part of exploring the work quality and production efficiency of the printer, as well as the attention that should be paid to the operation. The paper used in the trial printing is preferably stencil or coated paper. The paper requires good flatness and uniform thickness. The cutting specifications should be consistent. The edges of the paper should be straight and square so that the printing can be accurate when the printing quality occurs. Judgment is a paper issue or a device issue. When testing, the packing material and thickness should be strictly in accordance with the specifications of the equipment, the printing pressure should be uniform, and the thickness of the ink layer should be appropriate. The printing plate structure used for the trial printing is preferably an anilox or five-character text version. It is printed on the same ink, the same ink layer (appropriately thinner) and printing speed, and printed twice in succession (normal printing speed). Layout registration conditions to assess the transfer of various parts of the printer and whether the lining is appropriate; the rules are stable and accurate. After trial printing, it is confirmed that the machine can be installed and adjusted without problems before it can be mass-produced.
First, a number of factors that should be taken into account when determining the installation position of a printer.
