Starting Frequency of Flat Screen Printing Machine

According to the survey, the starting frequency of the Flat Screen Printing Machine can’t be too high. Since the speed of the equipment is zero at the start of the machine. In the starting process, in addition to overcoming the load resistance torque, the electromagnetic torque overcomes the inertial masking of the rotating part. When the burden on the equipment is heavier than continuous operation, what effect will the startup frequency be too high? Let's take a look at it below.

If the pulse frequency is too high at start-up, the speed of the rotor will not keep up with the speed at which the stator magnetic field rotates, so that the position where the first step is completed is far behind the equilibrium position, and the rotor speed is not increased much in the subsequent steps, while the stator magnetic field is still It rotates forward at a speed proportional to the pulse frequency, so the distance between the rotor and the equilibrium position becomes larger and larger, and finally the step of the rotor falls outside the dynamic stability zone and the phenomenon of out-of-step or oscillation occurs, so that the motor cannot be started.
The starting frequency of various Flat Screen Printer is different. The engineers who focus on micro-stepping motor and stepping motor driver industrial control product program experts believe that the starting frequency should be determined according to the motor description data. Many high starting frequency motors are used. The dual voltage operation means that the starting moment changes from high voltage to low voltage, and the smaller the step size, the more suitable for high frequency starting, the larger the power, the more suitable for high-frequency operation.
From what have discussed above, the starting frequency should not be too high. When the flat screen printing machine starts, the frequency will be gradually increased.

Screen Printing Machine (Characteristics and Types)

Screen Printing Machine Characteristics Modern screen printing press generally by the plate, ink, embossing, feeding (including folding) and other institutions. Its working principle is: the first to be printed text and images made of plates, installed in the printing press, and then manually or by the printer to apply ink on the plate with text and images of the place, and then directly or indirectly turn Printed on paper or other substrates (such as textiles, metal plates, plastic, leather, wood, glass and ceramics), so as to copy the same print plate. Screen Printing Machine Tyes 1 Flat Screen Printing Machine . The flat screen is used to print on a flat substrate. Generally, the squeegee is pressed horizontally by the squeegee, and the substrate is replaced by the plate. 2 curved screen printing machine. The flat screen plate is used to print on the round substrate, generally the squeegee is fixed, the plate moves horizontally, and the substrate rotates with th...

Inaccurate Registration of Rotary Screen Printer

When two or more patterns of registrations are printed, all or part of the patterns on the printed fabric are staggered or overlapped, which is seriously inconsistent with the original, called inaccurate registration. (1)Constant Inaccurate Registration Constant Inaccurate Registration means that the registration is not inaccurate from the start of driving, and the corresponding pattern always shifts from the original position or overlaps. The low impact factors of such problems can be found in the following reasons: the accuracy of the printing machine, the rotary screen and its plate making, the process, the operation, the printed fabric, and the patch pulp. (2)Inaccurate Left and right Registration That is to say, the registration is accurate in the middle, but inaccurate on the right or left. In this case, it is necessary to check whether the mechanical operation of the rotary screen printing part is normal; whether the film draft conforms to each set of film ...
