Roller supporting structure for mahjong tile cleaning and sterilizing machine

Abstract

The invention discloses a roller supporting structure for a mahjong tile cleaning and sterilizing machine with the characteristic of simple structure. The roller supporting structure for the mahjong tile cleaning and sterilizing machine comprises a supporting plate and a bearing which is arranged on the supporting plate, wherein a through hole capable of making a roller transmission shaft pass through is formed on the supporting plate; a blind hole for accommodating the bearing is formed on the supporting plate; and an axis of the blind hole is overlapped with an axis of the through hole and the diameter of the blind hole is greater than that of the through hole. During assembly, only by assembling the bearing into the blind hole and making the roller transmission shaft pass through an inner ring of the bearing and the through hole, the roller for cleaning the mahjong tiles can be assembled on the supporting plate, so that the assembling process is simple. Meanwhile, the distance between two adjacent rollers can be guaranteed. Therefore, the roller supporting structure has the advantages of capacity of guaranteeing the cleaning effect on the mahjong tiles, and suitability for popularization and application in a structure that a plurality of transmission shafts are needed to be assembled on the same plate.

Description

technical field [0001] The invention relates to a support device, in particular to a support structure for a roller of a mahjong tile cleaning and sterilization machine. Background technique [0002] At present, after the mahjong tiles are dirty, the mahjong tiles are mainly cleaned manually, and only a few tiles can be cleaned per hour, which is time-consuming and labor-intensive. Later, a device for automatically cleaning mahjong tiles appeared (patent number: 200920079394.9), which includes a hollow shell with a mahjong inlet and an outlet, and a support plate is fixedly connected in the shell, and a plurality of rollers are assembled on one side of the support plate The formed roller group is equipped with a motor and a transmission member on the other side, and the transmission shaft of the roller passes through the through hole on the support plate and is connected with the transmission member on the other side. When cleaning, the mahjong tiles enter between the rolle...

AI Technical Summary

Problems solved by technology

If the bearing seat is not assembled in place, it is easy to cause improper cooperation between two adjacent rollers. When the mahjong tiles are running between the roller groups, it is easy to cause blind areas on the mahjong tiles that cannot be cleaned by the bristles, so that they cannot be completely cleaned. The mahjong tiles are cleaned; in addition, the assembly process of the structure is complicated, time-consuming and laborious
