A two-position rack and pinion rotary device for a conveying line comprises the following specific details:

referring to fig. 1 and 2, at the top is a conveyor 1, and the conveyor line body is driven by a motor to move a belt of the line body so as to smoothly convey. The rotating member 2 is connected below the conveying member 1 by means of a support profile 21 and can be coupled together with the rotating member 2. The frame support 3 fixes the swivel bearing 24 through the fixed base plate 31 to provide planar support for the swivel 2. The rack gear 4 is connected below the fixed base plate 31 by a ball guide 41 to power rotation.

Referring to fig. 3, the rotary member 2 is constructed on a rotary fixing plate 22. The support profile 21 is fastened to the rotation fixing plate 22 by means of screws. The positioning and blocking profile 23 rotates the fixing plate 22 in a specific position. Providing conditions for rotational positioning. One end of a rotary transmission shaft 25 is fixedly connected with the rotary bearing 24 in the middle of the rotary fixing plate 22, and the other end of the rotary transmission shaft is connected with the driven gear 26 in a key connection mode to ensure the transmission of the rotary bearing. The driven gear 26 is reinforced by the gear fastening screw 27 with a washer so that the driven gear 26 cannot move axially.
