Main way of tension control
The tension control method is generally divided into two types: open loop control mode and closed loop control mode. The open loop control is to directly drive the winding mechanism with an electric motor having a similar winding characteristic n = kD (n is the rotational speed, k is a constant, and D is the diameter of the winding roller) to obtain an approximate constant tension operation. The open loop control has poor randomness and low control precision. The closed loop tension control has two kinds of direct tension control and indirect tension control. In the actual production process, the volume is adjusted, that is, the tension is fed back, compared with the given tension, and then the difference is applied to the regulator to adjust the controlled object so that the output tension meets the actual demand. It is called direct tension closed-loop control. This method can eliminate the steady-state error without considering various compensations. The indirect tension control uses the motor speed-torque characteristic curve to control the torque to control the torque, so as to achieve the purpose of controlling the tension. This method requires dynamic and static compensation. Sometimes, in order to obtain more precise control performance, a composite tension control method is adopted, that is, the required control amount is first determined according to an indirect control algorithm, and various compensations are considered to make the indirect control as accurate as possible, and then the direct tension control is used for fine adjustment.

Slip axis and air shaft of slitting machine--

 

Features:
1: Inflatable operation time is short, the separation and placement of the inflation shaft and the paper tube can be completed in 3 seconds to complete the inflation and deflation, and it is not necessary to separate any parts on the shaft end side to be tightly engaged with the paper tube.
2: The paper tube is simply placed: in the action of inflation and deflation, the paper tube can be moved and fixed at any position on the shaft surface.
3: The bearing weight is large: the diameter of the shaft can be determined according to the actual needs of the customer, and the high-hardness steel is used to make the bearing weight increase.
4: High economic efficiency: The design of the shaft is special, and it can be applied to all kinds of paper tubes of thick, thin, wide and narrow.
5: Simple maintenance and long use time: The inflation shaft is a single part, and each part in the structure has fixed specifications, which can be used interchangeably, making it easy to maintain.
Specifications: There are a variety of, including 1 inch, 1.5 inch, 2 inch, 2.5 inch, 3 inch, 6 inch, 8 inch, 10 inch, 12 inch, etc., according to demand can be processed to produce different specifications of the expansion axis.

5. Strategically lacking deeper cooperation with film-making companies
China has made tremendous changes in the economy in the past decade or so. Film-making enterprises have grown from scratch, from large to strong, and film-making enterprises have been listed on domestic and overseas stock markets, with dozens of them, and the key slitting machine industry is currently facing The small scale and low output value are extremely disproportionate to the scale of the film-making industry. There are two reasons for the above phenomenon: First, for the manufacturing of slitting machine enterprises, the opportunity has not been seized in time, and The knowledgeable film-making enterprises have jointly developed the domestic and foreign slitting machine market. Secondly, from the perspective of film-making enterprises, they have not been able to support some cutting-edge machine enterprises with promising prospects from reducing manufacturing costs, and jointly research and develop production slitting. device. If the film-making enterprises can reduce the purchase cost and operating cost, the price competition faced by today's film-making enterprises will be alleviated, and at the same time, the world-class cutting machine enterprises will be created.
