The present embodiment further includes a control center for calculating the difference between the width of the sheet material 100 and the farthest distance between the left and right shutter assemblies 24 and 25 to obtain the displacement required to move the left and right shutter assemblies 24 and 25 when the sheet material 100 is centered, and transmitting the displacement information to the displacement sensor. In this arrangement, when the width of the sheet material 100 is changed, the control center makes a difference between the width of the sheet material 100 and the farthest distance between the left and right shutter assemblies 24 and 25, so that the displacement required to move when the left and right shutter assemblies 24 and 25 center the sheet material 100 can be obtained, and the displacement information is transmitted to the displacement sensor, and when the displacement sensor detects that the left and right shutter assemblies 24 and 25 move to the preset displacement (i.e., reach the preset position), the control center controls the driving mechanism 3 to be turned off.

Therefore, when the plates 100 with different widths are centered, the displacement of the left baffle assembly 24 and the right baffle assembly 25 required to be moved can be calculated only by the control center according to the width of the existing plate 100 and the farthest distance between the left baffle assembly 24 and the right baffle assembly 25, so that the centering requirement of the plates 100 with different widths can be met, the baffle positions are not required to be manually adjusted, and the centering device is quite convenient. The control center may be a PLC controller.

It will be appreciated that after the assembly of the sheet centering device is completed, the furthest distance between the left and right baffle assemblies 24, 25 is determined, and the furthest distance between the left and right baffle assemblies 24, 25 is subtracted by the width of the sheet 100 and divided by two to obtain the displacement required to move the left and right baffle assemblies 24, 25.

It can be seen that the preset position is adaptively adjusted along with the width of the sheet material 100, and is calculated and analyzed by the control center.

It should be noted that, the width of the sheet material 100 is the distance from an edge of the sheet material 100 facing the left baffle assembly 24 to an edge of the sheet material 100 facing the right baffle assembly 25 when the sheet material 100 is placed on the carrier roller 11; the furthest distance between the left baffle assembly 24 and the right baffle assembly 25 is the distance from a surface of the left baffle assembly 24 facing the right baffle assembly 25 to a surface of the right baffle assembly 25 facing the left baffle assembly 24 after the left baffle assembly 24 and the right baffle assembly 25 are moved away from each other to the furthest position.

The pressure sensor can also be connected with the control center, and in the centering process of the plate 100, the pressure sensor transmits detected real-time pressure data of the left baffle assembly 24 and the right baffle assembly 25 to the plate 100 to the control center, and when the control center analyzes that the real-time pressure exceeds a preset pressure value, the control center sends out an alarm signal to warn a user.

It will be appreciated that when the plate centering device works normally, the real-time pressure detected by the pressure sensor is always smaller than the preset pressure value, and when the displacement sensor and/or the driving mechanism fail to cause the left baffle assembly 24 and the right baffle assembly 25 to stop at the preset position, the left baffle assembly 24 and the right baffle assembly 25 further squeeze the plate 100, at this time, the pressure data detected by the pressure sensor is transmitted to the control center, and the control center analyzes and compares that the real-time pressure exceeds the preset pressure value, and then sends an alarm signal to warn the user to maintain the equipment in time.

In terms of the number of the arrangement, since the pressures of the left and right shutter assemblies 24 and 25 to the plate material 100 and the displacement of the movements thereof are the same at the time of centering, it is sufficient to arrange a pressure sensor and a displacement sensor on one of the left and right shutter assemblies 24 and 25 for cost saving.

Because the structures and the distances of the pressure sensor and the displacement sensor are all in the prior art, the description of the embodiment is omitted.

It should be noted here that, the signal receiving, sending, data comparison and analysis and the like of the control center are all in the prior art, and are not described here again.

In order to facilitate understanding of the plate centering device of the present embodiment, the following description will be given with reference to the accompanying drawings, in which:

when the plate centering device centers the plate 100, the driving motor 31 rotates positively to drive the transmission shafts 32 and the commutators 33 to rotate positively, so as to drive the left-handed screw shafts 21 to rotate positively synchronously, so that the left-handed nuts 22 and the right-handed nuts 23 on the left-handed screw shafts 21 move close to each other, and finally the left baffle assembly 24 and the right baffle assembly 25 are driven to move close to each other, and meanwhile, the displacement sensor detects real-time displacement of the left baffle assembly 24 and the right baffle assembly 25, and when the left baffle assembly 24 and the right baffle assembly 25 move to preset positions, the displacement sensor transmits position information to the control center, and the control center controls the driving motor 31 to be closed, so that the plate 100 is centered;

when the plate centering device loosens the plate 100, the driving motor 31 reversely rotates to drive the transmission shafts 32 and the commutators 33 to reversely rotate, and further drive the left-handed screw 21 to reversely rotate synchronously, so that the left-handed nut 22 and the right-handed nut 23 on the left-handed screw 21 are far away from each other to finally drive the left baffle assembly 24 and the right baffle assembly 25 to far away from each other to loosen the plate 100, and the centered plate 100 is convenient to transfer to the next node.

According to an embodiment of the present utility model, in another aspect, there is provided a sheet material production line including the sheet material centering device of the present embodiment.

Of course, the above description is merely an optimal technical solution of the present embodiment, and further:

in some embodiments, centering mechanism 2 may be further configured with a movable baffle on one side and a fixed baffle on the other side, where after sheet material 100 enters centering roller 11, the movable baffle pushes sheet material 100 to one side of the fixed baffle under the action of driving mechanism 3 to achieve centering.

In some embodiments, the driving mechanism 3 may be further configured in a form of a rack and pinion matching transmission, that is, a gear is disposed on each left-right screw 21, the rack is meshed with all the gears, and the motor gear drives the rack to reciprocate, so as to drive all the gears to rotate forward or backward, so as to drive the left baffle assembly 24 and the right baffle assembly 25 on the left-right screw 21 to move close to each other to realize centering of the plate 100, or drive the left baffle assembly 24 and the right baffle assembly 25 on the left-right screw 21 to move far away from each other to realize loosening of the plate 100.
