Technical Field

The invention belongs to a matching device of rotary equipment in food processing machinery, and particularly relates to a tumbling machine.

Background

The tumbling machine is a key device for deep processing of meat equipment, and the tumbling barrel cover is an important part in the tumbling machine. According to the operation mode of opening and closing the cover, the cover of the barrel is divided into three types of manual operation, semi-automatic operation and full-automatic operation. The existing production gradually tends to be automatic, and the full-automatic barrel cover has the advantages that one-key operation can be realized only through a button, and automatic control is convenient to realize. With the increasing importance of society on the labor intensity of operators, the full-automatic barrel cover is more and more widely applied, and the trend of gradually replacing manual and semi-automatic barrel covers is existed. In order to realize full-automatic opening and closing of the barrel cover, a cover turning system formed by combining the barrel cover, the pressing arm and the driving is needed. The simplest connection mode between the barrel cover and the pressure arm device is rigid connection, and is also the connection mode of most barrel covers at present. Although this connection is simple, the biggest problem is the additional force caused by the coaxiality deviation of the drum cover and the rotation center of the tumbler during operation, which is commonly called 'stiffness'. The barrel cover is pressed on the barrel opening to rotate along with the barrel when the tumbling machine operates. Because the tumbling barrel usually needs to continuously operate, the additional force has huge destructiveness under the action of fatigue stress, and the bearing seat welded on the barrel cover can be torn along with the root in serious cases. In addition, the bearing, the oil seal and other parts in the bearing seat of the barrel cover are easy to damage in a short period under the action of additional force, so that meat materials in the barrel are polluted by lubricating oil, and great loss is caused to users. The problem is an inherent problem which puzzles the industry for many years, and the problem is researched and solved for a long time by domestic and overseas peers. Although other floating or semi-floating barrel cover devices have been proposed previously, they are not mature, either ineffective or cumbersome in construction, high in cost, and inconvenient to manufacture and operate.
