What is a printing machine?

Machines that print text and images. Modern printing presses generally consist of plate loading, inking, embossing, paper feeding (including folding) and other mechanisms. Its working principle is: first make the text and image to be printed into a printing plate, install it on the printing machine, and then apply ink to the place where the text and image are on the printing plate manually or by the printing machine, and then transfer it directly or indirectly Print on paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics) to reproduce the same printed matter as the printing plate. The invention and development of the printing press play an important role in the spread of human civilization and culture.

What role does grease play in printer maintenance?

When the machine is damaged, the manufacturer generally thinks it is caused by normal operation wear. However, today's machinery is made of high-quality alloy steel and should be able to be used for a long time. After that, after paying huge maintenance fees and the painful lessons of delaying production, manufacturers gradually began to discover the important role played by maintenance material teams in maintaining the normal operation of printing machinery. Among the many maintenance materials, lubricants and their Related chemical products are relatively neglected. Probably because of the correct selection of these materials, it will not cause immediate bad effects on the finished products produced by the manufacturer. Mechanical equipment is often used for a long period of time before it is found to have problems.

Introducing "grease" (snow oil). The type of grease can be roughly classified according to its hardness, pressure feedability, dripping point, water resistance and stability.

1 Hardness

Hardness, or penetration, is a measurable characteristic that must be considered when selecting an appropriate grease. The hardness of the grease is determined by the number. No. 0 is the softest, and then increases with No. 1 and No. 2 to No. 6. The hardness of No. 6 is the same as soap bar. The mud in the garden is easier to shovel and harder, and the hardness of the grease is the same. It is graded according to the penetration depth of the grease dropped from a certain height by the cone gauge. Printing machinery must add lubricating grease with appropriate hardness in accordance with the requirements of the printing press manufacturer, otherwise it may cause insufficient lubrication or increased resistance to the machine parts.

2 Pressure delivery

Another feature of grease is the difficulty of pressure delivery; in the central grease supply system, two types of grease that are equally easy to pressure delivery at room temperature, the pressure delivery performance is often very large in a lower temperature environment different.

The difference comes from the type and proportion of lubricating oil and soap contained in the grease. Some printing machinery and binding equipment use a central grease supply system to lubricate each component of the machinery. Therefore, it is extremely important to choose a grease with excellent pressure feedability.

3 Drop point

Because the grease contains different soap relationships, different greases will melt at different temperatures. The dripping point is the temperature at which the grease changes from semi-solid to liquid; most calcium soap grease melts at 160-210°F, sodium soap grease is 350-350°F, lithium soap grease is 350-400°F, so at high temperatures It is better to use sodium soap or lithium soap. Nowadays, the speed of most printing machines is quite high. Because the rotation speed of the motor bearing is higher, the bearing temperature increases accordingly. Choosing a grease with a higher drop point can make high-speed motor bearings such as "carbon pumps". "Bearings are better protected.

4 Water resistance

Regardless of whether it is in contact with water or not, some greases still need to perform their lubricating effect, so its water resistance is an important property. Calcium soap and lithium soap grease are insoluble in water, while sodium soap grease is soluble in water, so it cannot be used as a lubricant that may come into contact with water. The printing process needs to mix water, so some bearings must be protected by grease with good water resistance, otherwise, the service life of the bearing will be greatly reduced.

5 Stability

Some greases can still maintain their original hardness after being added to the bearing, which means that the stability is very high; this kind of grease can soften after working in the anti-wear bearing for a period of time, and will flow from the bearing without a good seal. come out. During the printing process, the powder spraying is continuous and has great coverage. If the stability of the grease used is poor, it will cause pollutants to easily enter the bearings and various components, causing great damage to the printing machine.

Traditionally, the design and production of grease has only focused on coping with the singleness problem faced by mechanical equipment. Such as high temperature, high speed, high pressure or anti-wear, etc. Later, due to the requirements of machinery manufacturers and the intensified market competition, the production of grease gradually tended to move in a multi-functional direction. However, ordinary petroleum products always have their limits in use, and they cannot effectively meet the rapid development requirements of modern production equipment. Although it is not easy to select the appropriate lubricant, there are also some professional lubricant suppliers in the market that can provide professional data and long-term after-sales service to reduce customer errors in use and avoid wasting precious time and money. You may wish to listen to the opinions of the industry, I believe it will help protect the good performance of the printing press.
