The present application discloses a speed-adjustable automatic limiting sausage stuffer. The sausage stuffer includes a rack and photoelectric sensors. A first limiting sensing hole is disposed on the top end of the rack, a second limiting sensing hole is disposed on the middle of the rack, and a perpendicular distance between the first limiting sensing hole and the second limiting sensing hole is a height of a barrel. The photoelectric sensors are disposed symmetrically on two sides of the rack, and when the first limiting sensing hole or the second limiting sensing hole on the rack is located on a same plane as the photoelectric sensors, the symmetrically disposed photoelectric sensors and the first limiting sensing hole or the second limiting sensing hole lie on a single straight line.

A portioning-twisting machine for producing cured sausages includes a product portioning element (3) and a twisting element (4) wherein portions are stuffed into a continuous casing and they are twisted. The portioning element (3) and the twisting element (4) are arranged so that the product moves between them linearly, i.e., without changing direction from when it is introduced into the machine to be portioned to its output forming stuffed units, after being twisted in the casing. The twisting element (4) is actuated in its rotation by a second motor (19), which operates independently from the first motor (10), which actuates the rotation of the portioning element (3). The transmission means (20) that link the second motor (19) to the twisting element (4) are accommodated and protected in a frame (21) provided externally on the side of the housing (2) and includes at least one belt (22).

The invention relates to an automatically-limiting electric sausage filler and control methods thereof. A piston is positioned at the tail end of a toothed piston rod and integrated as a whole; a DC motor drives an automatic shaft, the automatic shaft is meshed with the toothed piston rod through a gear train to drive the toothed piston rod to move up and down in a material cylinder, a meat outlet is formed at the bottom of the material cylinder, when the piston is arranged at the bottom of the material cylinder, the electric sausage filler has a lower limit; when the piston is arranged at the top of the material cylinder, the electric sausage filler has an upper limit; a lower limit signal detection element and an upper limit signal detection element are arranged on two sides of the toothed piston rod and correspond to an upper limit magnet strip and a lower limit magnet strip embedded on the toothed piston rod in an induction manner, and induction signals of the lower limit signal detection element and the upper limit signal detection element are sent to a control circuit which outputs a control signal to drive the DC motor to work. By virtue of the upper limit and the lower limit, the electric sausage filler is controlled to automatically fill sausages, overcurrent protection function is added in the control circuit for protecting the motor from stalling, so that a motor stalling protection device is omitted, and the cost is reduced; the sausage filling operation is simplified by virtue of the upper limit and the lower limit; and by virtue of the movement of the piston, the sausage filling process is fully automatic.
