Description

Technical Field

[0001] The utility model relates to the field of mahjong, and specifically to a transmission structure of a rotating frame with feeding and discharging ports on the end face. Background Art

[0002] The Chinese patent with the application number CN202310968423.1 discloses a multifunctional mahjong cleaning machine, which includes a drum cleaning mechanism (rotating frame) with a first brush head on the inner wall and a rotating shaft inside the drum with a second brush head on the outer peripheral surface. The drum cleaning mechanism includes a drum body and a drum door. The rotating shaft inside the drum is fixed to the drum cleaning mechanism. Therefore, when cleaning mahjong, the relative displacement between the brush head and the mahjong is very small, and the cleaning effect is not good.

[0003] The Chinese patent with the application number CN201911118591.1 discloses a conveyor-type mahjong cleaning machine, which relates to the technical field of mahjong machines. It includes a frame, a first transportation mechanism for guiding magnetic mahjong for preliminary cleaning, a first cleaning mechanism for preliminarily cleaning magnetic mahjong, a second transportation mechanism for guiding magnetic mahjong for secondary cleaning, a second cleaning mechanism for secondary cleaning magnetic mahjong, a third transportation mechanism for guiding magnetic mahjong for drying, a drying mechanism for drying magnetic mahjong, and a fourth transportation mechanism for storing magnetic mahjong. Although each of the six faces of each mahjong is cleaned one by one, due to high cost, the cleaning speed is slow.

[0004] The Chinese patent with the application number 201921836183.5 discloses a mahjong cleaning device, which includes at least two layers of rollers arranged from top to bottom. The number of rollers in each layer is at least two. The connecting line of the centers of the adjacent upper roller and the lower roller is inclined at 30 to 60 degrees. The cleaning area formed by the rollers has a structure that is wider at the top and narrower at the bottom. The rotating rollers (cleaning rollers) continuously rub and tumble the mahjong. This mahjong cleaning device has been widely sold on the market and is divided into two specifications to clean 36 - 50# and 52 - 64# mahjong respectively. When this mahjong cleaning machine cleans mahjong, the mahjong is stacked on the rollers, and the brush roller slowly squeezes the lower mahjong upward by centrifugal force. During this process, it is very difficult for the upper mahjong to move downward. Therefore, it takes a very long time to complete the cleaning of mahjong. In addition, the situation of scratching the pigment will occur. Content of the Utility Model
