Description

Technical Field

[0001] The utility model specifically relates to the technical field of winding structures, in particular to a tension regulating structure for calculating an actual winding diameter. Background Art

[0002] In industries such as laminating machines, the winding needs to maintain a certain tension, that is, the line speed remains unchanged. If center winding is used, the roll diameter will change in real time as the number of meters produced increases. At this time, the winding speed also needs to change in real time with the roll diameter.

[0003] The existing thickness accumulation method calculates the roll diameter by accumulating the number of rotations of the motor shaft. For every rotation of the motor, the roll diameter increases or decreases by two material thicknesses. The roll diameter calculated by this method is greatly affected by the material. If there is a deviation between the actual thickness and the set thickness, or the gap between the winding layers is inconsistent, it will have a great impact on the calculation of the roll diameter and there will be a cumulative error. To this end, we provide a tension adjustment structure for calculating the actual winding roll diameter to compensate for the above problems. Utility Model Content

[0025] Two sets of guide rods 60 are installed at positions inside the adjustment frame 6 that pass through both sides of the fixing seat 40 , and compression springs 61 are sleeved on the outer sides of the guide rods 60 and located below the fixing seat 40 .

[0026] In this embodiment, one end of the fixing base 40 is connected to an angle sensor 48 , and one end of the angle sensor 48 is electrically connected to a signal amplifier, and an output end of the signal amplifier is connected to a display for displaying the reading of the angle change.

[0027] In this embodiment, two groups of the first worm 42, the mounting support 43 and the adjuster 44 are provided, and the two groups of the adjusters 44 are installed at opposite positions.

[0028] In this embodiment, the second worm 46 and the first worm 42 are perpendicular to each other, and the second worm 46 is meshed with the first worm 42. The center of the second worm 46 is a steel rod structure, and the worms at both ends of the steel rod rotate in opposite directions.

[0029] The working principle of the utility model is: when in use, the processed coil passes between two sets of traction rollers 2, and is driven along the top of the transmission roller 3, and then reaches the surface of the winding shaft 5 along the bottom of the adjustment roller 4 for winding process;

[0030] In this process, the first worm 42, the regulator 44 and the second worm 46 are used in coordination, and the regulating disk 47 is manually rotated. Through the meshing action between the worms, the regulating roller 4 between the fixed seat 40 is synchronously controlled to move up and down, so as to control the tension balance in the winding process in real time, thereby reducing the winding diameter error in the winding process;

[0031] At the same time, since the horizontal distance between the adjusting roller 4 and the winding shaft 5 remains unchanged, the adjusting roller 4 is driven to deflect in angle by the angle sensor 48 at one end of the adjusting roller 4 during the continuous winding of the winding shaft 5. At this time, the angle sensor 48 detects the deflection signal, which is displayed on the display through the signal amplifier, thereby obtaining the vertical angle change. The horizontal distance c between the adjusting roller 4 and the winding shaft 5 is fixed. The top of the winding shaft 5 is preset as the initial vertex. Then the value obtained by the angle change of a is the change of radius, thereby the actual winding diameter can be obtained in real time.
