Problems solved by technology

In the existing grinding machine, the main shaft and the pulley are connected by a key, and the axial limit of the pulley on the main shaft is realized by the pin shaft. This kind of direction positioning effect is poor, and after a long time of use, the pulley is prone to damage. The phenomenon of offset slipping affects the use effect, and when the impeller in the grinder is fixing the blade, the blade mounting plate is not positioned on the impeller, so after the blade is installed, there is a large error, which affects the later use effect

Abstract

The invention discloses a driving impeller assembly in a sander. The driving impeller assembly comprises a main shaft, a belt wheel, an expanding sleeve and an impeller. The belt wheel is connected to the main shaft through the expanding sleeve, the belt wheel is fixedly connected with the expanding sleeve through screws, the main shaft is in key connection with the expanding sleeve, and the impeller is arranged on the main shaft in a sleeving mode, and is in key connection with the main shaft. The driving impeller assembly in the sander is good in fastening effect and reliable in connection, and the belt wheel does not slip; locating grooves can effectively locate a blade mounting plate, thus mounting is facilitated and errors are reduced.

Description

Technical field: [0001] The invention relates to a driving impeller assembly in a grinder. Background technique: [0002] The sieve ring grinder grinds the shavings into fine shavings, which are used as the surface material of the particleboard. It is composed of machine base, grinding screen ring, impeller, vibrating feeder, magnetic separation, heavy object separator and other parts, and grinds large shavings into fine shavings that meet certain process requirements. In the existing grinding machine, the main shaft and the pulley are connected by a key, and the axial limit of the pulley on the main shaft is realized by the pin shaft. This kind of direction positioning effect is poor, and after a long time of use, the pulley is prone to damage. Offset slippage affects the use effect, and when the impeller in the grinder is fixing the blade, the blade mounting plate is not positioned on the impeller, so after the blade is installed, there is a large error, which affects the...
