Tape Sealer Machine

Four release and one rewinding machine operation program ---

Second, the machine starts
1. Press the warning button and delay for about 2 seconds. At the same time, the alarm sounds, and then press the start button to start the machine.
2. When the machine starts, fine-tune the discharge roller to ensure that the material is flush at the receiving roller. During the fine adjustment process, the gear is not rubbed against the periphery.
3. When the machine is running, no objects are allowed between the ultrasonic probe and the material axis. This will cause the machine to stop working.


Third, automatic acceleration
When the accelerator button is pressed and delayed for about 3 seconds, the machine automatically accelerates to the required maximum speed (set in the touch screen), and the deceleration button is pressed once during the acceleration process to automatically accelerate and stop.

Design and application of constant tension and load distribution control for winder---

2Rewinder control research status at home and abroad
Rewinding machine is an important papermaking machine. It is usually installed behind the paper machine. Its speed should be 2-3 times of the speed of the paper machine, generally 1500-1800m/min, up to 300om/min. When threading, run at a maximum speed of 1:100. In order to ensure continuous paper and loose paper during the rewinding process, the tension of the paper web must be kept constant; in order to ensure the tight and loose quality inside the finished paper, the load distribution of the front and rear bottom roller motors must be performed. Therefore, the main performance requirements of the rewinder for the electric drive system are long-term linear speed, adjustable speed and wide speed range, and fast response.
The control of the early rewinder is mainly based on DC drive, and the DC control system is composed of discrete components or analog regulators to realize the above control functions. Since the transmission of analog signals requires a one-to-one physical connection, the signal changes slowly, which increases the overhead of computer speed and accuracy, and the anti-interference ability of signal transmission is poor, and paper breakage and wrinkling often occur in the production process. So in the mid-to-late 1980s, the analog regulator was replaced by a digital regulator, and the DC digital control system of the winder appeared. This control system is more stable, reliable and suitable for maintenance than the analog system, and is more suitable for interface with the factory computer. In the mid-1990s, most of the newly-invested rewinders in the domestic paper industry used all-digital DC-speed converters produced abroad, and the more famous ones were the 6RA7O series from Siemens and the 590 series DC-speed converters from Continental Transmission.
Due to the DC motor commutator and the brush, under the stable conditions, the design speed of the winder can only reach 1800m/mni, and the accuracy of the digital regulator is still limited to about 0.08% of the maximum speed, which can not meet the high speed paper. The matching requirements of the machine (the speed of the winder should be 2-3 times the speed of the paper machine). In the early 1980s, European and Japanese developed AC variable frequency speed control devices. This technology was successfully introduced to the United States in the mid-1980s and used in rewinders. The biggest advantage of the AC drive is that the AC motor is simple in construction and reliable in operation, and it requires much less maintenance and repair than DC motors.

Belt rewinding machine design and working principle ---

14 change roll
The roll change blower is used to blow the cut sheet onto the core. On the platen roller, there are three blowing tubes on the paper core with a blowing tube under the paper core. When blasting is used, the paper will bypass the core at the beginning of the machine.


15 paper cut hair dryer
The web cut blower is used when the web must be cut quickly. The blow tube is located between the guide rollers.
The blow tube is activated by a safety photocell or a manually transmitted pulse signal.
1- Spreading roller
2- Adjust the paper wrap angle device,
3- Stretch roller bending direction adjustment device
A- paper web
B- First stretch roll bending direction
C- second stretch roll bending direction
Stretching device
The stretching device on the illustration is the basic position of the display. The web A passes directly through the spreader roll, which means that the web curvature is zero. The first spreader roll B is at an angle of 90 degrees with respect to the sheet. The second spreader roll has a camber at the base position when the cylinder pressure is 0 bar. The cylinder pressure can be read on the meter at the location of the control system.
