The present invention discloses a mechanical type automatic catching and laying rail device, consisting of a hook seat, a hanging seat, a guide board, a clamping arm, and a link lever, wherein the hook seat consists of a hanging lug board, an upper gear ring, a lower gear ring, a screw rod, and a T-shaped hook, wherein the clamping arm is connected with the hanging seat by an axle on the hanging seat; one end of the link lever is connected with the hook seat by the axle, while the other end is connected with the clamping arm by the axle; the link lever is connected with the clamping arm to form a four-bar linkage structure; the four link levers are driven to displace by the upward and downward movement of the hook seat so as to open or close the clamping arm and achieve the steel rail catching movement and the steel rail laying movement; the upper gear ring is fixed in the hook seat, while the lower gear ring can be rotated along with the upward movement and the downward movement of the T-shaped hook; the mechanical self-locking and unlocking is realized by the rotation of the lower gear ring and the separation and joggling of the upper gear ring. The device does not need the drive of a power source, and is not restricted by the work environment. Just by the mechanical movement, automatic rail catching and laying can be realized. The device is simple in structure, convenient in operation, practical, reliable, lower in cost, high in economy, and high in practicability.

The invention provides an automatic bag folding and integrated packaging system, and belongs to the technical field of works. The automatic bag folding and integrated packaging system solves the problems that an existing bag folding and integrated packaging machine is low in working efficiency, and many workers are needed. The automatic bag folding and integrated packaging system comprises a rack and a bag folding trolley. The rack is provided with a horizontal roller conveying line, a falling control device with a supporting plate and used for controlling falling of bags and a high-speed conveying line connected with the roller conveying line in series and capable of conveying the bags to fall on the supporting plate. The bag folding trolley is located below the falling control device. According to the automatic bag folding and integrated packaging system, the roller conveying line can adjust the postures and intervals of the bags automatically, and workers in the corresponding processes are saved; the high-speed conveying line guarantees that the bags totally fall on the supporting plate, and the postures of the bags falling on the supporting plate are the same, and thus the corresponding adjusting personnel is saved; at the bag folding trolley, only one lifting worker is needed to arrange a hook ring for lifting the bags in a lifting hook of a lifting device in a sleeving mode, and the automatic bag folding and integrated packaging system has the advantage that the workers required by operation are less.
