The utility model adopts the lightweight optimization design, the long shaft of the square plansifter transmission mechanism is saved, the circular weight deflector is connected with the upper and lower short shafts, and the circular motion is carried out by the bearings in the upper and lower bearing blocks under the driving of the motor; the structure removes the long shaft, saves the material cost, integrates the long shaft and the weight bias into a whole, reduces the processing precision of the round weight block, saves the production preparation time and improves the production efficiency; in addition, the structure has the advantages of accurate transmission, simple structure, small mechanical abrasion, small vibration and stable operation, thereby prolonging the service life of the bearing and being safe and reliable.

Description

Novel transmission mechanism for square plansifter

Technical Field

The utility model relates to a novel drive mechanism for high square flat screen belongs to flat screen technical field.

Background

The transmission mechanism of the high square flat screen in the current market is basically composed of an integral long shaft, a weight block, a connecting block and a belt wheel which are connected with an upper bearing and a lower bearing for transmission, and the weight block connected to the long shaft through the connecting block makes circular motion around the long shaft. The suspended square plansifter body also makes circular motion under the reaction of the weight bias; because the height of the high square flat screen complete machine exceeds 2 meters, the shaft penetrating up and down is more than 2 meters, the required precision is high, the processing difficulty is high, vibration is easy to occur under the driving of the eccentric weight, and the service life of the bearing is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a novel drive mechanism for square plansifter that operates steadily, easy operation reduce cost improves production efficiency is provided.

In order to solve the above problems, the utility model adopts the following technical proposal:

a novel transmission mechanism for a square plansifter comprises a circular weight block, connecting blocks respectively fixedly connected with two ends of the circular weight block, an upper shaft and a lower shaft respectively fixedly connected with the connecting blocks at the upper end and the lower end, and a motor for driving the upper shaft or the lower shaft to rotate.

As a further improvement of the utility model, the upper shaft and the lower shaft are respectively and rotatably connected in the corresponding bearing seats; the two bearing blocks are respectively and fixedly installed at the top and the bottom of a steel frame of the square plansifter.

Adopt the produced beneficial effect of above-mentioned technical scheme to lie in:

the utility model adopts the lightweight optimization design, the long shaft of the square plansifter transmission mechanism is saved, the circular weight deflector is connected with the upper and lower short shafts, and the circular motion is carried out by the bearings in the upper and lower bearing blocks under the driving of the motor; the structure removes the long shaft, saves the material cost, integrates the long shaft and the weight bias into a whole, reduces the processing precision of the round weight block, saves the production preparation time and improves the production efficiency; in addition, the structure has the advantages of accurate transmission, simple structure, small mechanical abrasion, small vibration and stable operation, thereby prolonging the service life of the bearing and being safe and reliable.
