The invention can effectively improve the working condition and improve the efficiency of the roller press system.

Disclosure of Invention

In order to overcome the defect that the gap between the lower end of the adjusting insertion plate and the arc roller surface is changed greatly, and material leakage and pressure release are large, the invention provides the feeding adjusting device for the roller press.

The technical scheme adopted by the invention for solving the technical problems is as follows: a feeding adjusting device is arranged at the joint of a rectangular feeding chute of the roller press and the arc roller surface, and an adjusting inserting plate is pushed and pulled by a worm gear screw lifter and moves along a set slide rail groove curve. A bearing seat is arranged at the lower part of an end panel of the feeding adjusting device to fix a lower rotating shaft, the lower rotating shaft passes through a lower sliding rail groove of the adjusting inserting plate, a lower pulley is arranged at the end part of the lower rotating shaft, and the lower sliding rail groove of the adjusting inserting plate is matched with a lower pulley at the end part of the fixed lower rotating shaft to move up and down; an upper rotating shaft is fixed on the upper portion of the adjusting insertion plate, the middle portion of the upper rotating shaft is connected with a worm gear screw lifter, an upper pulley is arranged at the end portion of the upper rotating shaft, and the adjusting insertion plate, the upper rotating shaft and the upper pulley move in a curve mode along an upper sliding rail groove in a fixed sliding rail frame. Under the limit of the upper rotating shaft, the lower rotating shaft and the slide rail groove, the lower end of the adjusting plugboard is pushed and pulled by the worm gear screw lifter to move in a curve along the arc of the roller surface, the blanking cross-sectional area of the feeding chute of the roller press is changed, meanwhile, a small gap between the lower end of the adjusting plugboard and the arc roller surface is kept constant, material leakage and pressure relief are reduced, and the purpose of improving the effect of the roller press is achieved.

The invention has the advantages of reducing material leakage and pressure release and improving the efficiency of a roller press system while flexibly adjusting the feeding quantity of the roller press, along with simple structure.
