[0026] Spring 3 is specifically sleeved on linear bearing guide rod 6 and is tightly pressed by shaft fixing seat 2 and linear bearing 4 at both ends, linear bearing guide rod 6 top end passes through shaft fixing seat 2 and is connected top fixed plate 1 by screw thread, shaft fixing seat 2 is fixed on top fixed plate 1 by bolt, linear bearing guide rod 6 bottom end is slidably connected connecting plate 5 by linear bearing 4.By screwing linear bearing guide rod 6, the clearance of shaft fixing seat 2 and linear bearing 4 can be adjusted, and the initial deformation amount of spring 3 can be controlled.

[0027] Upper measuring roller bearing seat includes upper measuring roller bearing seat upper part 7 and upper measuring roller bearing seat lower part 10 which are split and connected by bolt, upper measuring roller bearing seat upper part 7 is fixed on connecting plate 5 by bolt, the rotation axis of upper measuring roller 11, i.e. upper measuring roller shaft 9, is rotationally connected upper measuring roller bearing seat at both ends by bearing 8, lower measuring roller bearing seat includes lower measuring roller bearing seat upper part 13 and lower measuring roller bearing seat lower part 14 which are split and connected by bolt, the rotation axis of lower measuring roller 12 is rotationally connected lower measuring roller bearing seat at both ends by bearing 8, proximity sensor 18 is installed at the bottom of lower measuring roller bearing seat lower part 14.

[0028] The stroke of cylinder 15 is 10 mm.

[0029] Encoder 17 is coaxially installed at one end of lower measuring roller 12 by coupling. Encoder 17 can rotate with the rotation axis of lower measuring roller 12.

[0030] Lower measuring roller bearing seat lower part 14 is made of nickel-titanium alloy, and has a gap at the lower part, in which proximity sensor 18 is installed. When the pressure exerted by upper measuring roller 11 is too large, lower measuring roller bearing seat lower part 14 will slightly deform, and the end surface of the gap will contact, triggering proximity sensor 18.

[0031] As Figure 5As shown, the linear bearing guide rod 6 includes a threaded head 19, a connecting rod 20 and a fixed pin 21 connected in turn, the threaded head 19 is threadedly connected to the top fixed plate 1, the height adjustment range is 3mm, the connecting rod 20 passes through the shaft fixing seat 2, the spring 3, the linear bearing 4 and the connecting plate 5 in turn. The deformation of the spring 3 can be controlled in the vertical direction.

[0032] The proximity sensor 18 has a trigger distance of 0.2mm, and is fixed in the lower gap of the lower measuring roller bearing seat lower part 14, and is triggered when the lower measuring roller bearing seat lower part 14 deforms and the deformation is large.

[0033] According to the above structure, when the transverse shearing line is started, the cylinder 15 pushes the cylinder connecting rod 16 to press down, at this time the lower part of the connecting plate 5 loses the restriction of the cylinder connecting rod 16, and will be pressed down under the elastic force of the spring 3, at this time the upper measuring roller 11 and the lower measuring roller 12 are in close contact with the material to be rolled and there is a certain pressure;

[0034] At this time, the pressure between the upper measuring roller 11 and the lower measuring roller 12 can be adjusted slightly according to the thickness of the material to be rolled, so as to achieve the pressure range of pressing the material to be rolled without damaging the material to be rolled, specifically:

[0035] 1) Rotating the threaded head 19 can adjust the height of the linear bearing guide rod 6, the shaft fixing seat 2 is fixed on the linear bearing guide rod 6 and changes in height together with the linear bearing guide rod 6, but the position of the linear bearing 4 is fixed, so the gap between the shaft fixing seat 2 and the linear bearing 4 will change with the rotation of the threaded head 19, at the same time, because the spring 3 is clamped at both ends by the shaft fixing seat 2 and the linear bearing 4, when the gap between the shaft fixing seat 2 and the linear bearing 4 changes, the deformation of the spring 3 will also change, and the pressure between the upper measuring roller 11 and the lower measuring roller 12 will change accordingly;

[0036] 2) When the thickness of the material between the upper measuring roller 11 and the lower measuring roller 12 changes, the top fixed plate 1 and the lower measuring roller bearing seat lower part 14 are fixed on the machine table and cannot change in height, so the height of the top fixed plate 1 and the lower measuring roller 12 does not change, when the material becomes thinner, the gap between the upper measuring roller 11 and the lower measuring roller 12 is smaller, the position of the linear bearing 4 is lower than that when the material is thicker, the gap between the shaft fixing seat 2 and the linear bearing 4 is larger than that when the material is thicker, at the same time, because the spring 3 is clamped at both ends by the shaft fixing seat 2 and the linear bearing 4, the deformation of the spring 3 is smaller, and the pressure between the upper measuring roller 11 and the lower measuring roller 12 is smaller than that when the material is thicker;

[0037] At this time, the encoder 17 will rotate with the forward or backward movement of the material to be rolled, the encoder 17 introduces the signal into QD62 through 6-core shielded wire, QD62 is directly connected with PLC, and the collected encoder data is introduced into PLC for collection and processing;

[0038] When the cross cutting line is stopped, the cylinder 15 lifts the cylinder connecting rod 16, at this time the connecting plate 5 is lifted upward by the cylinder connecting rod 16, the spring 3 is contracted under pressure, the upper measuring roller 11 is lifted upward with the connecting plate 5, the upper measuring roller 11 is out of contact with the lower measuring roller 12, and the material can be discharged.

[0039] The above described components are all prior art, and those skilled in the art can use any model and existing design that can achieve the corresponding functions.

[0040] The above described is only the preferred embodiment of the present application, it should be pointed out that, for those skilled in the art, without departing from the inventive concept, can make a number of deformation and improvement, these all belong to the protection scope of the present application.
