As a part of post-press mechanical equipment, A4 paper cutter is used to cut products of different specifications in the printing system. So, how is it formed?
The cutting process of the A4 paper cutter is mainly composed of a combination of a paper pusher, a paper press, a blade, and a side stop gauge.
1. The paper pusher can not only push the paper, but also can be used as a positioning rule;
2. The paper positioned by the paper press is pressed tightly to avoid errors caused by the movement of the blade under the cut;
3. The blade is usually made of hardwood or plastic, which can protect the blade and ensure that the paper is completely cut through;
4. The side stop gauge is perpendicular to the pusher to ensure that the two adjacent sides of the cut paper are perpendicular to each other.
The paper cutter is a kind of paper cutting equipment that is located between the electric paper cutter and the program-controlled paper cutter, is automatically roughly positioned by the control system, and then accurately positioned by manual fine adjustment.
Paper cutter is one of the necessary equipment for printing plants, it is mainly used for cutting paper. Nowadays, mechanized operations are generally adopted, which reduces the labor intensity of workers. Paper cutter is one of them. The cutting of the paper cutter depends on the blade on the paper cutter, which is one of the important parts of the paper cutter. The sharpness and service life of the cutting blade greatly affect the working efficiency of the cutting machine. When using a paper cutter, pay attention to safety, so safe operation is required.
The paper cutter adopts infrared cutting position indicator line and diagonal knife cutting technology. It has multiple safety protection designs such as transparent safety shield in front of the knife, synchronous button cutting with both hands, and current overload protection. There is no sliding knife phenomenon, and the accuracy can reach within 0.3mm. ; Touch button operation panel, double button to start work; rack-type rear-end positioning locking adjustment design, convenient for batch work.
The blades of paper cutters are very important, and the new cutters are very knowledgeable in their use.
The new blade equipped with the paper cutter needs to be used after the edge is cut. The new knife that has just been sharpened will sometimes have a cut and pull phenomenon during cutting. Many people think that it is a knife flower. In fact, this is a misunderstanding. , Because this pull-out phenomenon will disappear naturally as the cutting amount increases. Observed through the magnified environment, this is caused by the adhesion of the sharpened steel shavings to the blade, which is usually called a burr. The burr will automatically fall with the continuous action and friction of the blade, which is essentially different from the knife flower. Therefore, after the grinding is completed, in order to make the cutting edge sharper and smoother, after the cutting blade is sharpened, use a stone to sharpen the blade, and then use bamboo pieces (wood or plastic) to stay along the blade. The granular burrs on the blade are scraped off, and engine oil (rust prevention) is applied to the blade to prolong the service life of the blade and make the finished edge smoother. If you find that there are blades pulling paper on some of the cutting surfaces during the cutting work, you should polish it with oil stone at any time.
On the one hand, the quality of the blade and whether it is reasonable will directly affect the cutting quality. On the other hand, the unreasonable sharpening angle and use will seriously damage the accuracy and life of the paper cutter. It seems to be a matter of detail, but if improperly operated, it will have a profound impact on the quality of the printed matter and production efficiency, and must be highly valued and concerned.
Program-controlled paper cutter is a paper cutting method that realizes the automatic positioning of the paper pusher through the program control system and can also perform the positioning method of the electric paper cutter. Points to note when using a programmable paper cutter.
1. When starting the cutter, you must pay attention to the surrounding environment to see if anyone is doing other work on the machine.
2. The first thing to check after starting the machine is whether the photoelectric protection switch of the paper cutter is abnormal, to ensure the reliability of the machine.
3. If an unexpected situation occurs after driving, or there are abnormal sounds and jams, you must stop immediately to check the cause.
4. It is strictly forbidden to reach into the rear of the cutting knife during the operation of the machine. It is strictly forbidden to change or adjust the hand under the knife in the parking situation in time.
5. The control part must be checked frequently, the machine is not allowed to have a little bit of knife at any time.
6. After using the long-handle bolts and handles for the knife change and test drive of the paper cutter, they must be removed to avoid injury to people when the machine is started.
7. When repairing, adjusting, refueling, wiping and inspecting the machine, the power supply must be cut off to avoid danger.
Double guide paper cutters are used in the current paper processing industry, so what should users pay attention to when choosing this kind of equipment?
When choosing a double guide paper cutter, you should pay attention to the following points:
1. Mechanical structure
We know that the earliest mechanical paper cutter basically used a monorail structure, with a simple structure and very convenient operation, but the cutting accuracy was poor. The cutting accuracy of the double-rail paper cutter on the market is very high, which is more suitable for high-level printing and cutting.
2. Security of the equipment
The safety performance of paper cutter products is often criticized by people. In the past, we often heard from the news that XX was cut off by the paper cutter and so on. With the development of science and technology, such things happen very rarely, but when purchasing a double-rail cutter, it is best to test its safety performance.
3. Work efficiency and cutting accuracy
The working efficiency of the double guide paper cutter is a factor that many customers choose at present. It is necessary to perform accurate cutting in high-efficiency work. It is best to carry out professional on-site measurements when purchasing equipment.
4. After-sales service
The double guide paper cutter is a large product, and various problems may occur in the future production link. Therefore, after-sales service for manufacturers is the primary consideration for product purchase. In general, after-sales service is a reflection of the comprehensive capabilities of product manufacturers.
