Bi-directional rotary grinding head of retreading machine

Abstract

The invention discloses a bi-directional rotary grinding head of a retreading machine; the bi-directional rotary grinding head comprises a fixed plate, an outer rotary millstone, an inner rotary millstone and a middle shaft which is connected with a power unit; the inner rotary millstone is arranged on the middle shaft; a transmission device is connected between the middle shaft and the outer rotary millstone; the transmission device is a planetary gear train; the planetary gear train comprises a first sun gear, a first planetary gear and a first inner gear ring; the first sun gear is arranged on the middle shaft; the first planetary gear is arranged on the fixed plate; the first inner gear ring is fixedly connected with the outer rotary millstone; after the structure is improved, the inner rotary millstone is directly arranged on the middle shaft; and the outer rotary millstone acquires power through two stages of transmission, so that the structure is greatly simplified, and the manufacturing cost and the maintenance probability are reduced.

Description

Technical field: [0001] The invention relates to a bidirectional rotating grinding head of a refurbishment machine. Background technique: [0002] After being used for a period of time, the surface of these board-type building materials such as stone and ceramic tiles will be eroded by pollutants, resulting in dirty and tarnished surfaces. Especially for places with high requirements such as hotels and clubs, stone or ceramics must be treated. The bricks are refurbished and polished, and the refurbishment work is completed by a special refurbishment machine. In order to solve the large reaction force, difficult operation, and laborious operation of a single turntable, the traditional refurbishment machine has designed a two-way rotating grinding head, that is, the grinding head is composed of two In order to drive the inner rotating grinding disc and the outer rotating grinding disc to rotate in opposite directions, the manufacturer's transmission structure design is relativ...

[0002] After being used for a period of time, the surface of these board-type building materials such as stone and ceramic tiles will be eroded by pollutants, resulting in dirty and tarnished surfaces. Especially for places with high requirements such as hotels and clubs, stone or ceramics must be treated. The bricks are refurbished and polished, and the refurbishment work is completed by a special refurbishment machine. In order to solve the large reaction force, difficult operation, and laborious operation of a single turntable, the traditional refurbishment machine has designed a two-way rotating grinding head, that is, the grinding head is composed of two In order to drive the inner rotating grinding disc and the outer rotating grinding disc to rotate in opposite directions, the manufacturer's transmission structure design is relatively complicated. The inner rotating grinding disc is not directly installed on the central shaft, and the inner rotating grinding disc Both the grinding disc and the external rotating grinding disc need to go through several stages of transmission to obtain the rotational power. The transmission efficiency is low and the structure is more complicated, resulting in higher cost and maintenance probability
