[0031] The working principle of the four-roller plate rolling machine provided by this utility model which is easy to adjust is as follows:

[0032] Sheet curling processing:

[0033] When the plate is rolled, the motor in the four-roller plate rolling machine body 1 starts, driving the lower roller 22 to rotate; since the upper roller 21 and the lower roller 22 are connected by a gear transmission, the upper roller 21 also rotates synchronously;

[0034] The plate is fed between the four rollers. As the upper roller 21 and the lower roller 22 rotate, when the position of the side roller 23 needs to be adjusted to accommodate plates of different specifications or shapes, the cylinder inside the device pushes the two side rollers 23 to work;

[0035] Roller cleaning process:

[0036] After the sheet material curling process is completed, or when the roller surface needs to be cleaned, the two side rollers 23 and the lower roller 22 are first reset to their initial state by the cylinder;

[0037] Then, the electric push rod 5 is started, and its output end pushes the connecting plate 4 to move; this action causes the conical friction groove 96 on one side of the connecting plate 4 to tightly squeeze the conical friction wheel 91, achieving direct power transmission;

[0038] At this time, the operation of the four-roller plate rolling machine body 1 can drive the hollow pulley 2 93 to rotate through the transmission mechanism 9; through the belt transmission, the two hollow pulleys 1 92 also rotate synchronously, thereby driving the four rollers to rotate simultaneously;

[0039] At the same time, the meshing action of the driving gear 94 and the driven gear 95 causes the square rod 6 to rotate; one end of the square rod 6 is slidably connected to the reciprocating screw rod 7, thereby driving the reciprocating screw rod 7 to rotate;

[0040] The reciprocating motion of the reciprocating screw 7 drives the cleaning base plate 2 to move back and forth on the limiting rod 14; the slider 10 on the inner wall of the cleaning base plate 2 ensures that the folding cleaning plate 3 can move stably with it;

[0041] Prior to this, the folding cleaning plate 3 has been pulled and pressed against the slope 11 and fixed to the cleaning base plate 2 by bolts 13, ensuring that the cleaning brush surfaces of the cleaning base plate 2 and the folding cleaning plate 3 are in close contact with the surfaces of the four rollers;

[0042] With the rotation of the four rollers and the reciprocating motion of the cleaning bottom plate 2 and the folding cleaning plate 3, impurities such as metal chips on the surface of the rollers are effectively removed, keeping the rollers clean and preparing for the next processing.

[0043] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
