Rewinding Machine safety operation guide -
Seventh, production operations and quality control during the rewinding process:
1. The speed must be slow when rewinding, and the inspector should check the appearance quality of the paper.
2, often check the quality of the paper, found that the paper disease stopped in time, to the inspector on duty
Report and contact the upper and lower processes to strip off paper with quality problems. The rewinding can be continued after the inspector confirms.
3. When rewinding, pay attention to the situation of broken ends, trimming, etc., and control the tension of the paper during rewinding.
The car is tight) to keep the inner and outer tension of the paper roll consistent.
Guolian Small Winder Introduction---
First, the function: a variety of tape defective products re-rolled
Second, the characteristics:
A. The take-up shaft is driven by a DC 1HP motor and can be steplessly changed.
B. Automatic counting, convenient for setting the length of the winding.
C. The rewinding tension is adjusted by the spring, and the tension adjustment is convenient.
D. The structure of the machine is light and compact, and it is a desktop device, which is convenient to move.
Third, the specifications
1. Roller surface width: 105mm
2. Maximum discharge diameter: standard is 150mm and length is 400mm
3. Take-up diameter: Ø76mm-300mm
4. Rewind width: 12mm-100mm lengthening type is 300mm
5. Take the paper heart: paper tube 3”
6. Mechanical speed: 0~150M/min per minute
Fourth, the host configuration
1. Discharge shaft: 3" movable type (1)
2. Dispensing rack: lengthened 300mm diameter (1)
3. Main motor: DC motor 1HP (1 set)
4. Take-up tension: Spring control (1 set)
5. Length control: four-digit electronic counter (1 group)
6. Take-up shaft: 3" tube core (1 group)
Design and application of constant tension and load distribution control for winder---
2. Main research content
(1) On the basis of understanding the working principle and production process of the rewinder, determine the AC drive configuration scheme of the rewinder and the common DC bus power supply mode.
(2) In view of the influence of the change of the winding diameter on the tension during the rewinding process and the phenomenon of paper break and loose paper during acceleration and deceleration, a composite tension control method combining direct tension and indirect tension is proposed, and the real-time calculation and dynamics of the winding diameter are designed. Torque compensation program that effectively corrects tension disturbances to ensure constant tension during rewinding
(3) Software and hardware design to complete the pressure control of the platen roller”
(4) After detailed analysis of the causes of the load distribution of the bottom roller motor before and after the detailed analysis, determine the master-slave control scheme of the two motors, design the load distribution control system.
(5) Establishing a profibus-Dp network system, designing communication between pLC and inverter! Op operation panel"
(6) Using STEP7 to design the software of the rewinder control system, using ProTool to compile the entire monitoring system screen"
