A method for preparing a batch of animal feed from a plurality of ingredients

Abstract: A batch of animal feed from a plurality of ingredients is prepared in a mixer/feeder wagon (1) where the ingredients require respective predefined mixing periods during a mixing cycle in the mixer/feeder wagon (1). The mixer/feeder wagon (1) comprises a mixing compartment (14) in which a mixing rotor provided by a paddle mixer (17) is rotatably mounted. Stationary chopping blades (42) mounted in a base (43) of the mixing compartment (14) co-operate with the paddle mixer (17) for chopping fibrous material during the mixing cycle. The appropriate predefined mixing periods required for the respective ingredients are determined in order to avoid over-mixing and under-mixing of the ingredients, and the predefined mixing period is defined as the number of revolutions of the paddle mixer (17) to which that ingredient is to be subjected. The duration of the mixing cycle is defined as the number of revolutions of the paddle mixer (17) to which the ingredient which requires the largest number of revolutions of the paddle mixer (17) is to be subjected. The ingredient which requires the largest number of revolutions of the paddle mixer (17) is loaded into the mixing compartment (17) at the commencement of a mixing cycle. The counts of revolutions of the paddle mixer (17) from the commencement of the mixing cycle at which the respective remaining ingredients are to be loaded into the mixing compartment (14) are determined so that the number of revolutions of the paddle mixer (17) remaining in the mixing cycle from the count at which each ingredient is to be loaded into the mixing compartment (14) is equal to the predefined number of counts of revolutions of the paddle mixer (17) to which that ingredient is to be subjected by the paddle mixer (17).

Two-way stirring paddle

Abstract: The utility model provides a two-way stirring paddle. The two-way stirring paddle comprises a motor, a rotating shaft and a shaft sleeve. The rotating shaft is rotationally sleeved in the shaft sleeve through a bearing, a small paddle blade is arranged on the side wall of the shaft sleeve, a large paddle blade is arranged at the bottom of the rotating shaft, a first driven bevel gear is arranged on the top of the rotating shaft, a second driven bevel gear is arranged on the top of the shaft sleeve, a driving bevel gear is arranged on the output shaft of the motor, and the driving bevel gear is simultaneously meshed with the first driven bevel gear 3 and the second driven bevel gear. The motor can simultaneously drive the rotating shaft and the shaft sleeve to reversely rotate, then the paddle blades on the rotating shaft and the shaft sleeve can be driven to rotate, so that two-way stir is achieved; a mechanical sealing part is arranged, therefore, the bearing can be prevented from being affected with damp and damaged caused by the situation that liquid enters the two-way stirring paddle, and the service life of the bearing is prolonged.

Lead frame and bottom lead semiconductor package using the lead frame

Abstract: A lead frame includes a pair of guide rails separated at a predetermined space; at least one dam bar for connecting the pair of guide rails; a die paddle for mounting a semiconductor chip between the dam bar; a tie bar for supporting the die paddle; a plurality of leads each consisting of a first lead having a predetermined length extended from the dam bar between the dam bar and the die paddle, a second lead connected electrically to the first lead and formed bent in a first direction, and a third lead connected electrically to the second lead and formed bent in a second direction.

Fan folding and stacking device

Abstract: This device is for use for fan-folding and stacking a continuous web of business forms and operates as the last stage of such processing machine. The device includes a pair of rotatable paddle wheels disposed on each side of the processing machine frame and having an axis of rotation perpendicular to the longitudinal axis of the frame. Each paddle wheel includes a hub rotatable in a plane parallel to the axis of the frame and a plurality of radially extending lengthwise adjustable arms pivotally attached to the hub for transverse movement out of and into the plane of rotation of the hub for selective engagement with the continuous web. The transverse movement of the arms is controlled by a circular cam fixedly attached to the frame and engageable by cam followers attached to said arms.
