Brief introduction of commissioning and maintenance of printing operation process

The factors that affect product quality are nothing more than five factors: human, machine, material, method, and environment. Paper problems and equipment problems are the main aspects of the two major factors of machine and material. In addition to the design and manufacturing links, printing process, machine debugging, and maintenance, these five factors can not be ignored. Only these contradictions and problems are completed. Solved, the efficiency of the machinery and equipment can be maximized, and the unity of nature and man can be truly achieved, and the highest quality of printing can be achieved.

Poor maintenance of equipment such as lack of oil on the gripper shaft bearing, dust and ink on the tooth brace, movement of the gripper opening and closing is blocked, insufficient force to bite or even dead teeth;

The dental tablets and dental pads are worn or low-recessed, the contact surface is reduced, and the tooth gap between the dental tablets is filled with paper gray paper hair, and the friction rate between the teeth and the pad is small;

Fatigue failure of gripper small springs, false gripper paper, the paper will slip during printing, open ball wear, cam wear, handover synchronization time will be reduced;

The shaft and bearing on the end face of the roller are worn, and the axial clearance increases. When the roller shaft rotates at high speed, excessive axial movement will occur;

Improper selection of raw and auxiliary materials, excessive viscosity of ink, incorrect calculation of lining in the operation process, and large relative sliding amount between cylinders during printing all have a negative impact on the accuracy of paper transfer.

Corten Steel Bbq Grill

Method one: Corten steel BBQ Grill, spread a layer of charcoal in the charcoal oven and pile into a pyramid, leaving a little gap; Pour a little alcohol, gasoline and other accelerant to fully absorb charcoal, about a minute, the best in the bottom of the charcoal; The prepared strips of paper are lit and placed in the furnace, and the alcohol begins to burn, followed by the charcoal.Method two: Put combustible materials (such as dry grass, dried leaves and other dried plants) on the bottom layer of the charcoal oven; The carbon according to the pyramid shape stacked on the combustible, stacked when leaving a small gap for ignition; Use a lighter to light the flammable material directly in the small space. Combustible material up fire will slowly ignite charcoal, charcoal completely red, you can rest assured barbecue.Finally, the charcoal finally began to burn, red flame out, accompanied by a small amount of black smoke is a normal phenomenon. After burning for TEN minutes, the open flame gradually decreases or disappears, and white ash appears on the surface of the charcoal, which indicates that the ideal barbecue temperature has been reached, and the charcoal can be evenly spread out.
