The structure of the anti-stuck plate device 9 is a gate-type structure, specifically including a first base 13, a second base 17, a first column 14, a second column 16 and a third crossbeam 15. The lower end of the first column 14 is fixedly mounted on the first base 13, the lower end of the second column 16 on the opposite side is fixedly mounted on the second base 17, the upper end of the first column 14 is connected to one end of the third crossbeam 15 and the upper end of the second column 16 is connected to the other end of the third crossbeam 15. The third crossbeam 15 is a substantially planar structure, the plane of which is perpendicular to the first column 14 and the second column 16 and extends a distance toward the direction of the strip running (such as Figure 1 With the structure of the anti-stuck plate device 9, the third crossbeam 15 of the anti-stuck plate device 9 can give a downward pulling force to the head of the strip steel 1, so as to send the head of the strip steel 1 back to the original operation line, thereby smoothly and continuously operating.
[0031] In the preferred embodiment of the slitting and shearing anti-stuck plate system provided by the utility model, as Figure 1 As shown, the second fixing seat 11 is provided with a connecting base 10 on both the operating side and the transmission side.
[0032] In the preferred embodiment of the slitting and shearing anti-stuck plate system provided by the utility model, as Figure 1-2 As shown, the first base 13 and the second base 17 are fixed on the connection base 10 on the operating side and the transmission side respectively. Such a structure facilitates better fixing of the anti-stuck plate device 9 on the second fixing base 11.
[0033] In the preferred embodiment of the slitting and shearing anti-stuck plate system provided by the utility model, as Figure 1-2 As shown, the first base 13 and the second base 17 are fixed to the corresponding connecting base 10 by fixing bolts 5 respectively.
[0034] In the preferred embodiment of the slitting and shearing anti-stuck plate system provided by the utility model, as Figure 2 As shown, the first base 13 and the second base 17 are identical and are made of steel plates. This ensures the stability of the structure and makes it easy to manufacture the structural components of the first base 13 and the second base 17.
[0035] In the preferred embodiment of the slitting and shearing anti-stuck plate system provided by the utility model, as Figure 2 As shown, the first column 14 and the second column 16 are identical and are made of steel plates. This ensures the stability of the structure and makes the structural components of the first column 14 and the second column 16 easy to manufacture.
[0036] In the preferred embodiment of the slitting and shearing anti-stuck plate system provided by the utility model, as Figure 1As shown, the upper shear blade 2 is fixedly mounted on the first fixing seat 4 by means of bolts and nuts.
[0037] In the preferred embodiment of the slitting and shearing anti-stuck plate system provided by the utility model, as Figure 1 As shown, the lower shear blade 6 is fixedly mounted on the second fixing seat 11 by means of bolts and nuts.
[0038] In the preferred embodiment of the slitting and shearing anti-stuck plate system provided by the utility model, as Figure 1 As shown, the second fixing seat 11 is connected to the second cross beam 12 via the adjusting bolt 7. Such a structure facilitates the second fixing seat 11 to move upwards by the rising of the second cross beam 12.
[0039] The new anti-stuck plate device 9 of the utility model is composed of five parts: a first base 13, a second base 17, a first column 14, a second column 16 and a third crossbeam 15, which are fixed on the second fixed seat 11 of the lower shear blade device 19 of the original equipment to form a gate structure. The strip steel 1 passes through the middle of the gate structure. When the above-mentioned slitting and anti-stuck plate system of the utility model is used and operated, the hydraulic cylinder raises the second crossbeam 12 and the second fixed seat 11 through the hydraulic cylinder connecting plate 8, thereby driving the lower shear blade 6 and the anti-stuck plate device 9 to rise, and work together with the corresponding upper shear blade 2 to cut the strip steel 1. The strip steel head on the right side of the upper shear blade 2 is pushed up by the lower shear blade 6, and then the hydraulic cylinder drives the lower shear blade 6 to move downward. Due to the force to the left, the strip steel head and the side friction of the upper shear blade 2 often cannot return to the original operation line position. At this time, the third crossbeam 15 of the anti-stuck plate device 9 will give a downward pulling force to the strip steel head, sending the strip steel head back to the original operation line. The hydraulic cylinder reciprocates to cut the steel strip 1, and the third crossbeam 15 of the anti-stuck plate device 9 also reciprocates to send the head of the steel strip back to the original operation line, thereby smoothly and continuously operating.
[0040] In the structure of the utility model used and operated as described above, preferably, the anti-stuck plate device 9 is made of steel and has a door-type structure. Figure 2 As shown, in a specific embodiment, the first base 13 and the second base 17 ( Figure 2 The left and right bases shown in the figure are made of steel plates with a size of 40 mm × 20 mm × 10 mm and are fixed to the first fixing seats 11 on the operating side and the transmission side, respectively.

The third crossbeam 15 is made of steel plates with a size of 1400 mm × 70 mm × 6 mm, and its two ends are connected to the first column 14 and the second column 16 respectively.
[0041] In summary, the above structure of the utility model mainly solves the problem of interruption of the unit operation caused by the slitting shearing plate, and the utility model is suitable for promotion on the unit of strip steel production. The utility model has strong practicality, simple structure, reliability and maintenance-free characteristics.
