Referring to fig. 6, the driven roller 210 includes a roller shaft and a hollow roller, the driven roller 210 has a hollow structure, a water injection pipe 211 communicating with the inside of the driven roller 210 is provided on an end surface of the roller of the driven roller 210, and a sealing cover 212 for sealing the water injection pipe 211 is provided on the water injection pipe 211. When the flatness of the steel sheet processed by the leveler is not up to the standard, the operator removes the sealing cap 212 from the water injection pipe 211 and then injects cold water into the driven roller 210. Further, the quality of the driven roller 210 is increased, the extrusion force of the driven roller 210 on the steel plate is improved, and the flatness of the steel plate after processing is guaranteed. The cold water is filled in the driven roller 210, so that the temperature of the driven roller 210 is reduced, the steel plate is cooled, and the problem that the steel plate is heated due to extrusion and cooled after being processed to generate secondary deformation, so that the steel plate is uneven and the use of the steel plate is influenced is avoided.

Referring to fig. 2 and 3, a pre-pressing roller set 5 is connected to the frame 1 on a side of the driving roller 310 away from the driving roller 320, the pre-pressing roller set 5 includes a main pressing roller 510 and a sub-pressing roller 520, the sub-pressing roller 520 is located at an upper end of the main pressing roller 510, an upper end of the main pressing roller 510 is located at the same height as an upper end of the driving roller 310, and a distance between the sub-pressing roller 520 and the main pressing roller 510 is greater than a distance between the driving roller 310 and the driven roller 210. When processing the steel sheet, operating personnel inserts the one end of steel sheet between main compression roller 510 and vice compression roller 520, makes vice compression roller 520 and main compression roller 510 carry out preliminary extrusion to the steel sheet, reduces the degree of buckling of steel sheet. By the preliminary pressing of the pre-press roller group 5, the degree of bending of the steel sheet is reduced, and the steel sheet is more likely to enter between the driving roller 310 and the driven roller 210.

Referring to fig. 2 and 3, one end of the main pressing roller 510 close to the first gear 311 is connected to a main pressing gear 512, and the main pressing gear 512 is connected to the chain 410 and further rotates along with the movement of the chain 410 to drive the main pressing roller 510 to rotate.

Because the distance between the driving roller 310 and the driven roller 210 is too small, an operator cannot easily insert a steel plate between the driving roller 310 and the driven roller 210, but the distance between the main compression roller 510 and the auxiliary compression roller 520 is large, so that the feeding of the operator is facilitated, and the working efficiency of the operator is improved. The main compression roller 510 and the auxiliary compression roller 520 both have the capability of driving the steel plate to move, so that the steel plate is pushed by a larger force, and the steel plate is easier to insert into the driving roller 310 and the driven roller 210. The pre-pressing roller set 5 increases the length of the steel plate to be processed in the flatting mill, so that the steel plate is more flat and smooth by extrusion, if the steel plate is shorter in length in the flatting mill, the processed steel plate is easy to bend, and the flatness of the steel plate is not up to standard. The pre-pressing roller set 5 improves the flatness of the steel plate and further improves the processing quality of the steel plate.

Referring to fig. 3, an adjusting groove 120 is formed in the frame 1 below the main pressing gear 512, an adjusting member 130 is slidably connected to the adjusting groove 120, an adjusting gear 131 engaged with the chain 410 is connected to the adjusting member 130, and a nut is threadedly connected to an end of the adjusting member 130 away from the adjusting gear 131 and fixes the adjusting member 130 in the adjusting groove 120. The operator adjusts the degree of tension of the chain 410 by adjusting the position of the adjusting gear 131. When the chain 410 is used, the tensioning degree of the chain 410 is increased through the adjusting gear 131, so that the transmission of the chain 410 is more stable and is not easy to separate from each gear. When the chain 410 needs to be repaired, the tension applied to the chain 410 is reduced by the adjusting gear 131, so that the chain 410 can be conveniently detached from each gear. Because the tensioning degree of the chain 410 can be adjusted, the range of the chain 410 suitable for the flattening machine is enlarged, and the chain 410 in the flattening machine can be matched conveniently by an operator.

Referring to fig. 2, one side of the pre-pressing roller set 5, which is far away from the upper pressing roller set 2, is provided with a deviation rectifying assembly 6, the deviation rectifying assembly 6 comprises a slideway 610 connected with the frame 1, and the slideway 610 is slidably connected with a butt plate 620. When an operator inserts one end of the steel plate into the pre-pressing roller group 5, the steel plate is prone to being inclined, and once the steel plate is brought into the flattening machine, the steel plate is difficult to be pulled out of the flattening machine. The steel sheet is askew and gets into the flatting mill or the motion track of steel sheet in the flatting mill takes place to be crooked, all easily makes the edge of steel sheet fold or buckle appear, makes the roughness of steel sheet not up to standard, reduces the processingquality of flatting mill, and in case appear crooked, can only wait to the whole roll of steel sheet processing completion, and resources are wasted and the cost, wants to take out the steel sheet from the flatting mill, and consuming time is hard, reduces machining efficiency. Abutting plate 620 plays limiting displacement to the steel sheet, and the both sides of steel sheet all with abutting plate 620 butt, and then the motion track of restriction steel sheet, operating personnel insert the steel sheet in pre-compaction roller set 5 before, through abutting plate 620 with the steel sheet setting, reduce the crooked probability of steel sheet, and then guarantee that the motion track of steel sheet is perpendicular all the time with the length direction of drive roller 310, improve the roughness of steel sheet.

Referring to fig. 7, a clamping member 630 is arranged on the abutting plate 620, the clamping member 630 is a bolt, and after the operator adjusts the position of the abutting plate 620, the operator rotates the bolt to abut one end of the bolt against the slideway 610, so as to clamp the abutting plate 620 on the slideway 610. The abutting plate 620 is prevented from being loosened, and the movement track of the steel plate is changed.

The implementation principle of the embodiment is as follows: when the steel plate needs to be processed, an operator starts the driver 110, the driver 110 drives the driving gear 111 to rotate, the driving gear 111 drives the chain 410 to rotate, and the chain 410 drives the adjusting gear 131, the main pressing gear 512 and the first gear 311 to rotate. Thereby rotating the main pressure roller 510, the sub pressure roller 520, the driving roller 310, and the driving roller 320.

Subsequently the operator adjusts the position of butt plate 620 according to the width of steel sheet, makes the both sides of steel sheet respectively with two butt plate 620 butts, and the position of butt plate 620 is locked to rethread chucking spare 630. Then, one end of the steel plate is inserted into the pre-press roller group 5, and the steel plate is pressed by the main press roller 510 and the sub-press roller 520, reducing the degree of bending. Then the steel plate is pushed to one side close to the driving roller 310 by the main pressing roller 510 and the auxiliary pressing roller 520, is inserted between the driving roller 310 and the driven roller 210 after being pushed to the driving roller 310, is pushed to the direction close to the driving roller 320 by the driving roller 310, is further extruded by the driven roller 210 and the driving roller 320, and is extruded and flattened.

If the hardness of the steel plate is high, an operator closes the driver 110, rotates the driven roller 210, injects cold water into the driven roller 210 through the water injection pipe 211, increases the mass of the driven roller 210, further increases the pressure applied to the steel plate by the driven roller 210, and ensures the flatness of the steel plate.
