The utility model provides a lower adjustable evener, includes evener organism 1, is equipped with leveling roller 2 and lower leveling roller 3 on the evener organism 1, go up leveling roller 2 and rotate the upper beam of connection at evener organism 1, the upper beam is fixed on evener organism 1, lower leveling roller 3 rotates the underbeam of connection at evener organism 1, underbeam sliding connection is on evener organism 1, elevating system 4 is installed to 1 bottom of evener organism, the underbeam at evener organism 1 is fixed to the lift end of elevating system 4, install reinforcing roller mechanism 5 on the upper beam of evener organism 1 and the underbeam respectively, reinforcing roller mechanism 5 and the 2 laminating of last leveling roller on the upper beam, reinforcing roller mechanism 5 and the 3 laminating of lower leveling roller on the underbeam mutually. The lifting mechanism 4 comprises a motor 41, a connecting rod 42, a worm 43, a worm wheel, a screw rod and ball nuts, the body of the motor 41 is fixed on the leveling machine body 1, the output shaft of the motor 41 is fixed at one end of one worm 43, the worm 43 is fixedly connected with the other worm 43 through the connecting rod 42, the two worm 43 are respectively meshed with the two worm wheels, the worm wheel is in key connection with the screw rod, the ball nuts are in threaded connection on the screw rod, and the outer rings of the two ball nuts are respectively fixed at two ends of a lower beam of the leveling machine body 1. Reinforcing roller mechanism 5 is by linear module 51, threaded rod 52, spring 53, stop nut 54, support 55, roll body 56 and inclined plane block group become, threaded rod 52 is worn to be equipped with respectively by the upper beam and the underbeam of evener organism 1, threaded rod 52 one end threaded connection has stop nut 54, the threaded rod 52 other end is fixed on support 55, it is connected with roll body 56 to rotate on the support 55, linear module 51 is fixed respectively with by the upper beam and the underbeam of evener organism 1, sliding fit is connected with the inclined plane piece on linear module 51's the cylinder body, the inclined plane piece is fixed on linear module 51's ball nut, the inclined plane and the support 55 laminating of inclined plane piece mutually, the cover is equipped with spring 53 on the threaded rod 52, spring 53 is located between stop nut 54 and the upper beam of evener organism 1, go up evener 2 and lower evener 3 laminate mutually with roll body 56 respectively.

As shown in fig. 1, two worms 43 are fixed together by a connecting rod 42 and connected to form a linear rod. Each worm 43 meshes with a worm wheel, and a lead screw connected with the worm wheel is perpendicular to the worm 43. The rotation of the output shaft of the motor 41 drives the left and right worm screws 43 to rotate synchronously. The rotating worm 43 drives a worm wheel which engages with it, which in turn drives a vertical screw to rotate. The rotating screw rod drives the ball nut in threaded connection with the screw rod to move linearly up and down along the screw rod. Thus, the left and right ball nuts can drive the lower beam of the evener body 1 to synchronously move up and down, so that the lifting of the lower evener roll 3 can be realized.

The interval between the lower leveling roll 3 and the upper leveling roll 2 is adjusted by controlling the elevation of the lower leveling roll 3. After the lower leveling roll 3 is moved into position, the motor may be turned on to rotate the lower leveling roll 3 and the upper leveling roll 2 to extrude the strip.

Because the lead screw is vertical setting, consequently can utilize the dead weight to eliminate the screw thread clearance for the lift size is more accurate.

The reinforcing roller mechanism 5 attached to the upper leveling roller 2 is located above the upper leveling roller 2, and applies a pressure from top to bottom to the upper leveling roller 2 when the roller body 56 is pressed down, thereby offsetting the pressure of the strip against the upper leveling roller 2 from bottom to top.

The reinforcing roller mechanism 5 attached to the lower leveling roller 3 is located below the lower leveling roller 3, and applies a pressure from bottom to top to the lower leveling roller 3 when the roller body 56 presses up, thereby offsetting the pressure of the strip against the lower leveling roller 3 from top to bottom.

The operation mode of the intensifying roller mechanism 5 is that the screw rod of the linear module 51 rotates to drive the ball nut on the screw rod to move linearly, the slope block fixed on the outer ring of the ball nut moves linearly along the cylinder body of the linear module 51, the slope of the slope block moving linearly pushes the support 55 to move up and down, and the threaded rod 52 on the support 55 moves up and down along the through hole of the upper beam or the lower beam. During the movement of the threaded rod 52, the spring 53 expands and contracts with the stop nut 54 on the threaded rod 52, and the return is assisted by the rebound of the spring 53.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
