Strip edge trimming lines with oscillating winder

800 type transversal rewinding machine

800 dynamic plate precision Traversing recoiler Technology

1. Technical performance:

1.The whole is welded with high-quality steel plates to ensure quality and long-term use without deformation. The winding speed is controlled by the tension wheel, and the tension is kept constant during the winding process; the coiling is driven by the linear guide and the ball screw to drive the winding system to move forward and backward to arrange the strips, ensuring that the wire is in a straight line during the overall rewinding process without damaging the strips.

21. Used for rewinding 800 strip coils;

2. Wire specifications: width: 9-30mm; thickness 1.5-2.0mm or less;

3. There is no overlap during the material collection process;

4. The traction machine line speed is 0-150m tracking and adjustable, and the strips take-up machine automatically tracks the traction machine speed to keep the tension constant. The electric control cabinet has a reserved interface, and other processes can be configured during the rewinding process.

5. The servo controller, programmable controller, and module are of Delta brand;

6. The 800 winder can be operated with the traction machine or separately.

 Working environment requirements:

1. Ambient temperature is not higher than 40℃;

2. Voltage and fluctuation: 380V±10%;

3. Frequency: 50Hz±2%;

800  traversing  rewinding machine

The 800 traversing -rewinder  machine includes: a fixed base frame, a mobile frame, a wire arrangement mechanism, a transmission part, a wire drum expansion and contraction part, a strips pressing part, and an electric control cabinet.

Base frame and mobile frame: Made of high-quality steel, welded by CO2 gas shielded welding, and processed after aging treatment. The mobile frame is installed on the linear guide rail on the low frame, and reciprocates through the ball screw connection transmission to complete the wire arrangement action, ensuring the stable and reliable performance of the whole machine after assembly.

Wire arrangement mechanism adopts PMI linear guide rails and ball screws to ensure the accuracy of strips arrangement. A servo motor is installed at one end to drive the mobile frame of the strip-receiving and strip-releasing machine to reciprocate wire arrangement through the ball screw.

Transmission part The power is transmitted from the output of the 15kw servo motor to the reducer, and the reducer is transmitted to the spindle. Finally, the coupling disk at the front end of the spindle drives the strips-receiving and wire-reducing reel to rotate.

Wire drum expansion and contraction part The whole is divided into 4 plates. In order to improve the expansion and contraction roundness, a slider mechanism is used for expansion and contraction. The expansion and contraction spindle sleeve adopts a detachable structure and is connected to the transmission spindle keyway bolt. The inner sleeve at the front end of the transmission main shaft expands and contracts, and the expansion and contraction of the expansion and contraction part is controlled by turning the handle.

Strip pressing part When the wire arrangement is used, the wire pressing part is at a high position. When the strip arrangement function is not used for winding, the strip passing speed regulating lifting frame is at a high position, the strip pressing wheel is pressed down to the specified position, and after winding to a certain number of layers, the wire pressing wheel rises a certain distance, and the touch screen displays the current strip  pressing wheel position in real time. The distance between the strip pressing wheel shaft and the winding reel makes the wire taking-up positioning wheel and the winding reel at a suitable distance to ensure that the strips does not collapse, and the up and down adjustment is controlled by a stepper motor lead screw.

Wire passing wheel at the feeding end. The strips feeding guide wheel part is installed on the sliding table lifting as a whole, so that the strips feeding fixed wheel is as close to the strips reel as possible to ensure the quality of wire arrangement.

。

C. Control method:

a. The strip arrangement collects the encoder signal of the servo strips taking-up motor through the PLC to calculate, so that the strips arrangement mechanism keeps synchronization with the wire taking-up.

b. The speed of the strip is collected by driving the photoelectric encoder through the strip wheel to feedback to the PLC to achieve the accuracy of the meter and wire speed.

D. Strip  traversing arrangement technology:

After years of careful research, development, practice and summary by our company, an effective wire arrangement method has been developed to effectively solve the problem of strip advance or lag caused by strip stacking and reversing during the wire arrangement process, and the current position of the strip  arrangement is displayed in real time to ensure the flatness of the wire arrangement.
