High-speed indexing separator

Abstract

The invention discloses a high-speed indexing separator. The high-speed indexing separator comprises a power input cam, a power output rotating tower and a power output shaft, wherein the power input cam is in transmission connection with the power output rotating tower; the power output rotating tower is in transmission connection with the power output shaft; a plurality of roller pairs are distributed around the power output rotating tower in the radial direction, and each roller pair comprises a forward rotating roller and a backward rotating roller which are structured the same; supporting ribs with driving curve outlines are arranged on the power input cam; the roller pairs are positioned in clearances which are formed through the circularly-distributed supporting ribs; the forward rotating rollers and the backward rotating rollers of one roller pair are correspondingly in contact fitting with the surfaces of the supporting ribs at two sides of the clearances; and the forward rotating rollers and the backwards rotating rollers of adjacent roller pairs fit two surfaces of the supporting ribs at the same position. The high-speed indexing separator is long in service life; the rotating speed of the high-speed indexing separator in actual work is doubled that of a traditional separator, so that the efficiency of the separator as well as a production line of the separator can be extremely improved.

Description

technical field [0001] The invention relates to a production equipment, in particular to a high-speed intermittent divider. Background technique [0002] Divider is a mechanism used to realize intermittent motion. It has high indexing accuracy, stable operation, large torque and compact structure. It can perfectly replace traditional cam and ratchet mechanisms and play a huge role in various processing fields. [0003] In the existing intermittent divider, the supporting rib on the input cam includes alternate and continuous stop sections and dividing sections. The two ends of the supporting rib are generally arranged as dividing sections, and the circumference between the supporting rib and the roller on the output turret is linear. Contact, through the alternate contact between the support ribs on both sides of a single roller and the rollers, the cycle of division, stop and division is completed, so as to achieve the purpose of intermittent rotation of the output turret; ...

[0003] In the existing intermittent divider, the supporting rib on the input cam includes alternate and continuous stop sections and dividing sections. The two ends of the supporting rib are generally arranged as dividing sections, and the circumference between the supporting rib and the roller on the output turret is linear. Contact, through the alternate contact between the support ribs on both sides of a single roller and the rollers, the cycle of division, stop and division is completed, so as to achieve the purpose of intermittent rotation of the output turret; in actual operation, when performing division, the traditional support ribs and The mating surfaces of the rollers alternate, causing the rollers to switch between forward rotation and reverse rotation. At this time, sliding friction will occur between the rollers and the supporting ribs; since the speed of the traditional splitter can generally reach 500~700r / min, in each The sliding friction that occurs in each division will cause the divider to generate high heat, which will not only seriously affect the service life and safety of the divider, but also greatly limit the rotation speed of the divider
