Cup holding assembly for a food mixing machine
View Patent ↗A food mixing machine ( 20 ) has an agitator ( 25 ) to mix food in a cup (C). A cup holder ( 31 ) is provided with a flexible boot ( 32 ) which receives the cup (C). The cup holder ( 31 ) is moveable through an opening ( 90 ) in the machine ( 20 ) and carries a gripping assembly ( 33 ) and an actuator assembly ( 34 ). The actuator assembly ( 34 ) is moveable relative to the gripping assembly ( 33 ) and is biased by springs ( 35 ) to maintain fingers ( 56 ) of the gripping assembly ( 33 ) in engagement with the cup (C). When it is desired to release the cup (C), a release assembly ( 80 ) overcomes the bias of the springs ( 35 ). As the cup holder ( 31 ) moves through the opening ( 90 ), the area between the cup holder ( 31 ) and the opening ( 90 ) is sealed by a seal assembly ( 91 ) so that food materials cannot go through the opening ( 90 ).
1. A machine using a rotating agitator to mix food in a cup comprising a housing, an opening in said housing, a cup holder adapted to receive the cup and to be moved through said opening, and a seal assembly carried by said housing around said opening, said seal assembly including a seal to engage said cup holder as said cup holder moves through said opening.
2. The machine of claim 1 wherein edges define said opening, said seal assembly engaging said edges.
3. The machine of claim 2 wherein said seal is a gasket and said seal assembly includes a first plate carrying said gasket, a second plate, and means to attach said first plate to said second plate with said gasket and said edges between said first and second plates.
4. The machine of claim 1 further comprising a gripping member positioned with said cup holder, and an actuator moveable relative to said gripping member so that said gripping member can selectively engage a cup positioned in said cup holder.
