Bottle lifting device for filling machine

Abstract

The invention relates to a bottle lifting device for a filling machine. The bottle lifting device comprises a false cup, a bottle clamping plate, and a cylinder which is arranged above a filling valve; a roller seat on which a roller is arranged is arranged on a telescopic part of the cylinder; guide rods are respectively arranged at two sides of the roller seat; one end of each guide rod, far away from the roller seat, is connected with the false cup; the bottom end of the false cup is connected with the bottle clamping plate; the false cup is positioned below an opening of the filling valve; axes of the cylinder and the filling valve and a longitudinal center line of the roller are overlapped. According to the bottle lifting device for the filling machine, the roller, the false cup, the bottle clamping plate, the filling valve and the cylinder are connected as a whole structure; the cost is small; when in filling, the cylinder upwards moves under the effect of compacted air, and the bottle clamping plate is driven by the roller seat together with the guide rods to move upwards, so as to prop a bottle opening to the opening of the valve for filling; after the filling, the roller downwards moves, and the bottle clamping plate is driven by the guide rods to downwards move, so as to enable a bottle to be separated from the opening of the valve; the force applied during lifting or lowering is concentrated in the direction of the axis of the filling valve, so that the filling precision can be effectively increased.

Description

technical field [0001] The invention relates to filling equipment technology, in particular to a bottle lifting device of a filling machine. Background technique [0002] The lifting device and the filling valve of the traditional filling machine are two separate and independent parts. The lifting device is below the filling valve and installed on the machine through a fixing piece. Drive the bottle up and down, and the clamping plate lifts the bottle to the sealing place of the filling valve bottle mouth. There is a suspended arm between the two parts. At the place, it will cause poor sealing, air leakage at the bottle mouth during filling, and the guide ring of the lifting device is prone to unilateral force and wear during the lifting process, which will affect the life of the seal and cause air leakage due to poor sealing of the lifting device. Especially for gas-containing filling, a slight vibration will cause the beverage in the bottle to foam and overflow the bottle...
