Web cutting machine
The web cross-cutting machine is suitable for vertical and cross-cutting of reel materials such as whiteboard paper, gold and silver cardboard, plain rainbow paper, positioning laser anti-counterfeiting paper, and plastic sheet. The computer part of the web cross-cutting machine is composed of industrial control computer, 5.5" color digital display, imported frequency converter, photoelectric sensor, AC servo motor and driver which embody international advanced technology. The whole machine control mode is advanced, the main machine and servo motor will be used. The speed of the three feeding motors is controlled centrally by the computer to achieve synchronous operation. It has the advantages of high cutting precision, fast speed, convenient feeding, etc. It can also be equipped with paper humidification, drying and leveling system to make the paper straight and stereotyped.
Slitting and rewinder
The slitting and rewinder is a special equipment for papermaking. Its purpose is to rewind the paper rolls produced by the paper machine (called the original paper roll), and the paper is re-rolled to make the finished paper. At present, the AC drive of the slitter rewinding machine has replaced the DC drive in the industry of slitting and rewinder. The paper roll taken by the reel is relatively soft, the inside may be damaged or broken, the edges on both sides are not neat, and the width of the paper width can not be directly used in machines such as paper processing or printing. Most paper types (such as newsprint) , letterpress printing paper, wrapping paper, etc.) must be cut, spliced, jointed, and re-rolled on the paper core to form a finished paper roll with certain specifications and certain tightness requirements before leaving the factory. The rewinding process mainly accomplishes three tasks: one is to cut off the raw paper burrs; the other is to cut the whole original paper into a number of widths that meet the user's specifications; and third, to control the winding diameter of the finished paper roll to meet the factory specifications. .

How to better use the web cross cutter:
First, we must do a good job of maintenance and maintenance. First of all, daily maintenance should be in place, the standard is that smooth, clean, clear (no dust, no debris) in place, to ensure that the sliding part of the equipment is in good condition.
Followed by maintenance work, stop regular and irregular inspections of the rotating parts (especially stop real-time monitoring of consumables). Regular adjustments are made, regular changes are made, commutators are carefully recorded, and the purpose of extending the service life of the equipment is achieved.
Then, the electric appliance should be cleaned and inspected regularly to remove hidden dangers in time.
Second, the use of high quality slitting knife and cross cutter.
Third, improve the technical quality and degree of the operator, the control of the local operation to be a special person to serve, without permission, no one can operate.
Basically, after the maintenance method described above, the use time of the web cross-cutting machine will increase, so that everyone can use the equipment better!

In the die-cutting production, the roughening of the trimming is one of the common faults, and the reasons can be summarized as follows:
First, the cutting edge of the die cutter is deformed and dull
If the die-cutting pressure is too large, the number of die-cutting times increases, and there are sand grains on the semi-finished products, it is easy to deform and blunt the die-cutting blade edge, resulting in rough edges of the product. Therefore, the pressure at the edge of the die-cutting blade should be as small as possible so that the trimming material can be cut off. In addition, the deformed, dull die-cutting knives should be replaced in time to ensure a smooth cut of the product.
Second, the sponge strip is too hard and too thick, causing the cutting edge of the die cutter
If the sponge strip is too hard or too thick, it will inevitably produce a large pressing force on the edge of the die cutter when it is pressed, which will easily deform the edge of the die cutter, causing rough edges of the product. In this regard, a softer sponge strip should be chosen and the thickness of the sponge strip should be reduced as appropriate.
Third, the die-cutting plate is repeatedly patched
Adding pressure on the die-cutting plate to increase the pressure is a commonly used adjustment method in die-cutting production. However, after repeated feeding of the paper, the surface of the die-cutting plate will be uneven, the flatness will be poor, and the die-cutting will also cause The product is rough and trimmed.
4. There are knife marks on the die-cut base.
The die-cutting base plate has been used for a long time, and there are dense and knives on the surface, which is also likely to cause rough edges of the product. In this case, replace the new die-cutting plate.

After the web cross-cutting machine is finished, clean the dust and paper scraps on the equipment in time, check the cutter and the sharpening grinding wheel, drain the oil in the water purifier and the water in the gas storage tank, and check whether there is any abnormality in the running part. . Then, according to the instructions, cut off the power supply and maintain the computer operating system.
Do a good job of maintenance and maintenance. First of all, daily maintenance should be in place. The principle is to lubricate, clean, clean (no dust, no debris) in place to ensure that the sliding part of the equipment is in good condition. Followed by maintenance work, regular and irregular inspections of the rotating parts (especially for real-time monitoring of consumables).
Regular adjustments are made, regularly replaced, and detailed records are made to extend the life of the equipment. Regular cleaning and inspection of the electrical parts should be carried out in a timely manner to eliminate hidden dangers. Use high quality slitters and cross cutters. Improve the technical quality and level of the operator, and be responsible for the operation of the control part. No one can operate it without permission.

      Cross-cutting machine is one of the important single machines of corrugated board production line. The cross-cutting machine has different mechanical control modes, and is divided into a mechanical cross-cutting machine and a computer-controlled cross-cutting machine. The computer cross-cutting machine is controlled by the industrial control computer. According to the set length, the cutter shaft is controlled to cut the cardboard, and the precision transmission of the mechanical part can control the cutting error within ±1mm. The computer controlled cross cutting machine has a spiral cutter cross cutter and a straight knife cross cutter. The spiral cutter cross-cutting machine is more suitable for high-speed cutting of thick cardboard, and the cutting paper is stable and the blade has a long service life.
      The cross cutter is suitable for longitudinal and transverse slitting of various types of paper. Such as gold and silver cardboard, plain rainbow paper, laser laser security paper, white paper and all kinds of thin paper. Widely applicable to horizontal or vertical shearing of trademarks, cigarette labels, calendars, wine boxes, poker, paper-plastic composites.
      Note for crosscutting machine:
      First, we must do a good job of maintenance and maintenance.
      First of all, daily maintenance should be in place. The principle is to lubricate, clean, clean (no dust, no debris) in place to ensure that the sliding part of the equipment is in good condition.
      Secondly, it is maintenance work, and regular and irregular inspections of the rotating parts are required (especially for real-time monitoring of wearing parts). Regular adjustments are made, regularly replaced, and detailed records are made to extend the life of the equipment. Regular cleaning and inspection of the electrical parts should be carried out in a timely manner to eliminate hidden dangers.
      Second, the use of high quality slitting knife and cross cutter.
      Third, improve the technical quality and level of the operators, to the control part of the operation to be responsible for the person, without permission, no one can operat
