fig. 2 is a control schematic diagram of the present invention.
Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.
As shown in fig. 1 and 2, the present invention provides a strip tension stabilizing apparatus, including: a dancing roller assembly 1, a tension roller assembly 2 and a controller.
The dancing roller assembly 1 consists of three rollers including: the roller fixing device comprises an intermediate roller 102, a first fixing roller 101, a second fixing roller 103 and a driving piece 104, wherein the intermediate roller 102 is arranged between the first fixing roller 101 and the second fixing roller 103, and the output end of the driving piece 104 is connected with the intermediate roller 102. In this embodiment, the first fixed roller 101, the intermediate roller 102, and the second fixed roller 103 are disposed horizontally in sequence, and in other embodiments, they may be arranged obliquely or vertically, or they may not be in a straight line, which is not limited in this invention.
The tension roller assembly 2 includes: the first tension roller 201 and the second tension roller 202 are arranged at the rear end of the jumping roller assembly 1, and the second tension roller 202 is arranged at the front end of the first tension roller 201, so that the strip steel is connected to the tension roller assembly 2 in an S-shaped rolling manner, and the strip steel from the jumping roller assembly 1 is obtained.
The controller 3: the controller 3 is respectively electrically connected with the dancing roll assembly 1 and the tension roll assembly 2, and controls the driving member 104 to output corresponding pressure to the strip steel between the first fixed roll 101 and the second fixed roll 103 according to the tension required by the strip steel, and adjusts the rotating speed of the first tension roll 201 according to the stroke of the middle roll 102 or the driving member 104, so that the stroke is kept within a preset range.
In the present invention, the actuator 104 is a hydraulic cylinder, and the controller 3 controls the pressure of the hydraulic cylinder through a servo valve. The controller 3 detects the stroke of the driving member 104 or the intermediate roller 102 by the position sensor.
The working principle of the invention is as follows:
the strip steel is conveyed into the dancer roll assembly 1 after being deflected by the deflecting roll 4 and then conveyed into the tension roll assembly 2. The required tension is calculated according to the steel type, the thickness and the width of the strip steel, and the required tension can be acquired through a direct algorithm or a table look-up mode, and can be artificial or calculated through the controller 3.
The controller 3 controls the driving member to output corresponding pressure according to the required tension, that is, the intermediate roller 102 is driven to move downwards to press the strip steel between the first fixed roller 101 and the second fixed roller 102, due to the damping of the tension roller assembly 2, the tension of the strip steel will gradually increase during the downward movement of the intermediate roller 102, and the controller 3 controls the pressure output by the driving member 104 to drive the intermediate roller 102 to move downwards until the stress balance is reached (that is, the strip steel reaches the corresponding tension).
In the subsequent operation process, if the band steel is in a loose state (namely, the tension is reduced), the oil hydraulic cylinder drives the middle roller 102 to move downwards until the stress is balanced because the pressure in the oil hydraulic cylinder is greater than the force given by the external band steel; when the strip steel is too tight (i.e. the tension is too high), the pressure in the oil hydraulic cylinder is smaller than the force given by the external strip steel, and the output shaft of the oil hydraulic cylinder and the middle roller 102 move upwards until the stress is balanced.
Generally, the height of the intermediate roll 102 should be fixed at the middle position, however, the height of the intermediate roll 102 deviates from this position because the tension of the steel strip deviates from the pressure of the oil hydraulic cylinder inevitably. In turn, when the deviation is too large, it should be adjusted, and the present invention gives the following adjustment scheme:
setting a preset range of the stroke of the intermediate roller 102 or the driving member 104, and when the stroke of the intermediate roller 102 or the driving member 104 is larger than the preset range, controlling the controller 3 to increase the rotating speed of the first tension roller 201 to increase the tension of the strip steel, wherein the intermediate roller 102 and the driving member 104 move upwards due to the increase of the force from the strip steel; when the stroke of the intermediate roll 102 or the driving member 104 is smaller than the preset range, the controller 3 controls to reduce the rotation speed of the first tension roll 201, so that the tension of the strip is reduced, and at the moment, the intermediate roll 102 and the driving member 104 move downwards due to the reduction of the force from the strip.
The control principle of the invention is shown in figure 2:
the first tension roll speed is set as follows:
VSet＝Vl+VTech
in the formula: vset: representing a first tension roll speed set point; vl: representing the speed of the unit; vTech: representing the controller output value.
