Main factors affecting tension stability:
(1) The change of the speed of the machine will inevitably cause the change of the tension of the whole machine.
(2) During the process of collecting and unwinding, the winding and unwinding diameters of the slitting machine are constantly changing, and the change of the diameter will inevitably cause the change of the material tension. When the unwinding torque is constant, the diameter is reduced and the tension is increased. The winding is reversed. If the winding torque is constant, the tension will decrease as the winding diameter increases. This is the main factor that causes the change in material tension during operation.
(3) The change in the tightness of the raw material roll will also cause a change in the tension of the whole machine.
(4) The unevenness of the material of the raw material is cut. If the material elasticity fluctuates, the material thickness changes along the width and length direction, the mass of the material roll is eccentric, and the temperature and humidity of the production environment change, which also affects the tension fluctuation of the whole machine.
(5) The various transmission mechanisms (such as guide rollers, floating rollers, flattening rollers, etc.) of the slitting machine have factors such as imbalance and unstable air pressure.

Reasons, countermeasures and effects of BOPP film slitting quality ---

 

On the surface, slitting is the process of dividing a film of a width into several equal or unequal width products by a cutter. The slitting process is relatively simple, but often contains mystery in simplicity, in actual production. The slitting operation is a very important part in the production of BOPP film. The quality of the slitting will directly affect the quality level of the film and affect the quality of the user. Therefore, the quality of the slitting must not be underestimated in the film production process. . Only by fully recognizing the importance of the slitting process and fully grasping the basic essentials of slitting, can we minimize consumption and ensure the best product quality, in order to fully meet the needs of customers, and provide the most reliable product quality for BOPP film. Guarantee.

Domestic cutting machine development status and outlets ---

1. Not rigorous in the manufacturing process
Tolerance control in the mechanical manufacturing process is not precise enough, and the surface is rough, especially in the matching electroplating industry, which is shoddy. There is a defect in the dynamic balance of the roller for cutting the Chinese-made equipment at one time. The lag of the related industry, the rubber coated by the roller has far less wear resistance and anti-aging than the foreign products. The bearings used seem to use well-known foreign brands, but the counterfeit and shoddy floods the domestic bearing market. Even when the real goods are purchased, the precision is far lower than the precision used by foreign slitting machines.
In the entire production process of a slitting machine, there is no guarantee of production process. At present, most of the slitting machines produced in China are completed by a number of outsourcing units, and the quality of their production is even more difficult to guarantee. In addition, the metal materials used and the heat treatment process are not rigorous enough, resulting in many problems in the use of a slitting machine. It has seriously affected the share of a slitting machine in the domestic market. The secondary and tertiary slitting machines have fewer problems than the one slitting machine, because the parts of the secondary and tertiary slitting machines are completed by the slitting machine manufacturer, and the dynamic balancing machine used is in a narrow range. It can accurately control the unbalanced grams, and the industrial difficulty coefficient of manufacturing is reduced. Its selling price is far lower than that of foreign products. Therefore, the proportion of domestically produced slitting machines in the domestic slitting machine market getting bigger.
