Problems solved by technology

However, the above-mentioned rolling device still has the problem that the middle slider of the above-mentioned three-stage cross floating coupling is in a floating state and is prone to offset, and the offset of the middle slider will make it produce a larger The centrifugal force increases the dynamic load. After long-term use, the connection between the two coupling halves and the slide block is prone to wear, which in turn leads to unstable operation of the rolls. Especially in the above-mentioned prior art, since one of the rolls is It is connected to the output end through a rigid coupling, and there is no compensation function, so the floating compensation during operation must rely on the three-stage cross floating coupling, which leads to a large range of movement of the middle slider. Furthermore, the operation of the roll is not stable, which ultimately affects the uniformity of the particle density of the product

Abstract

A double-group shaft coupling rolling device provided by the invention comprises two half-couplings; two bottom surfaces opposite to the two half-couplings are respectively provided with a slotted groove and a slotted boss, which is nested in the groove; two output shafts drive the two fixed half-couplings to rotate reversely with a same velocity; and when the slotted groove of one half-coupling is parallel to a line, which centers of two rollers are on, the slotted groove of the other half-coupling is perpendicular to the line, which centers of two rollers are on. According to the couplings provided by the invention, as no floating block is arranged, a wear problem on a joint of the half-couplings and the slide blocks caused by large centrifugal force due to offset caused by slide blocks can be avoided. Compared with the existing technology of one group provided with a rigid coupling device and a group provided with a floating coupling device, the invention effectively reduces jump amplitude of the floating coupling, so as to ensure the stable operation of the roller.

Description

technical field [0001] The invention belongs to the field of powder forming equipment, and in particular relates to a double-group coupling rolling device for a dry granulator. Background technique [0002] Dry granulation is a granulation process that directly compresses the raw material powder through mechanical extrusion, and then crushes and granulates it. Compared with wet granulation, the dry granulation process omits the humidification and drying process, saving a lot of energy. of electric energy. Dry granulator is the basic equipment for pressing various low bulk density raw powders into high bulk density granules in pharmaceutical, powder metallurgy and other industrial sectors. [0003] Dry granulation is to realize the compression molding of raw materials through a rolling device. The rolling device includes a power mechanism, double rollers and output shafts arranged in parallel. The rollers are connected to the power mechanism through the output shaft, and the...
