Description

Motor vibration exciter

The technical field is as follows:

the utility model relates to an extensive application is in each trades such as light industry, chemical industry, grain, food, commercial, specifically is a multi-functional motor vibration excitor of high efficiency who realizes production flow in the commodity circulation such as feed, batching and quantitative automatic packaging that is used for likepowder and granular material.

Background art:

at present, a vibrating system of a vibrating feeder in the market uses a motor to drive an eccentric block to form vibration, and the vibration effect is poor. Two motors are also used for driving the eccentric block to form vibration, and the two motors are asynchronous and do not have natural frequency, so that the feeder cannot vibrate in a linear motion. And the eccentric block is not easy to adjust, and the vibration feeding effect is not good, so that the production efficiency is influenced.

The utility model has the following contents:

the utility model aims to solve the technical problem that an adopt two sets of symmetrical eccentric vibration mechanisms is provided, increase the spring and constitute adjustment system to the position of adjustment gear meshing angle and eccentric block changes the excitation direction of motion, thereby changes and carry the size of vibration angle, can produce linear motion and great vibration range, makes the motor vibration shock absorber that conveying efficiency and transport quality improve by a wide margin.

The technical scheme adopted by the technology for achieving the purpose is as follows: the motor of the motor vibration exciter is fixedly arranged in the front middle of a left motor base and a right motor base, a housing is fixed at the left end of the left motor base and the right end of the right motor base, eccentric blocks are symmetrically and fixedly arranged at the left end and the right end of a motor shaft respectively, a gear is fixed at the left top end of the motor shaft, a spring is movably arranged on the motor shaft between the gear and the left eccentric block, clamping sleeves are fixed at the left top end and the right top end of the motor shaft respectively and clamp the gear and the eccentric blocks respectively, and the gear at the left end of the motor shaft and the gear at the left end of a vibration.

The utility model has the advantages that: because two groups of symmetrical eccentric vibration mechanisms are adopted, a spring is added to form an adjusting system, so that the gear meshing angle and the position of an eccentric block are adjusted, the excitation motion direction is changed, the size of the vibration angle is changed and conveyed, linear motion and large vibration amplitude can be generated, and the conveying efficiency and the conveying quality are greatly improved. And the structure is simple, the power consumption and the abrasion are less, the disassembly and the assembly are convenient, and the service life is prolonged.
