started according to the lifting and transferring height required, The screw is driven to rotate in the component box, the external sliding frame starts to move up and down along the outer side wall of the conveying well in a threaded state under the condition that the component box is connected with the external sliding frame, and simultaneously drives the output linkage mechanism and the extending linkage mechanism to move up and down until reaching the transfer height, when the material placing roller frame drags the packing box to rise along the limiting slideway and reach the height of the transfer mechanism, a group of guide rollers on the material placing roller frame firstly contact and push up the arc-shaped supporting blocks contained in the output linkage mechanism until the arc-shaped supporting blocks are flush with the material placing roller frame, then the arc-shaped supporting blocks stop rising, the pushing force is formed temporarily, and the arc-shaped supporting blocks can be sleeved on the guide rollers of the material placing roller frame due to the structural characteristics of the arc-shaped supporting blocks, The short pushing of the guide roller of the material placing roller frame can drive the telescopic arm fixed at the tail end of the arc-shaped supporting block to slide along the inside of the rotating arm, the rotating arm starts to rotate along a certain angle along the bottom wall of the lower fixed rod, the L-shaped linkage arm fixed at the other end of the rotating arm rotates along the rotating direction of the rotating arm due to the displacement of the lower fixed rod, prying force is generated at the same time, the prying force promotes the L-shaped linkage arm to drag the guide rod connected with the bottom end

sliding frame, when the second pushing-out sliding frame slides along the linked sliding table to displace, one end of the first scissor bracket slides along the inner side wall of the linked sliding table, the first scissor bracket begins to unfold to form the pushing-out distance of the first stage, the second scissor bracket connected with the other end of the cross rod also unfolds due to the first scissor bracket and drives the first pushing-out sliding frame to displace along the linked sliding table to form the pushing-out distance of the second stage, while the scissor bracket II is continuously unfolded along with the scissor bracket I, one end of the scissor bracket II, which is close to the conveying well, is pushed out of the sliding frame I after sliding, the L-shaped sliding frame is pushed to start to displace along the linkage sliding table to form a third-stage pushing distance, and the expansion and utilization of the extending linkage mechanism self can lead the L-shaped sliding frame to push out the third-stage farther distance under the small-angle prying action of the L-shaped linkage arm, so that the pushed-out L-shaped sliding frame can synchronously push out and transport the packaging box which is lifted along with the material placing roller frame while the material placing roller frame contacts with the arc-shaped supporting block, the tail ends of the cross bars of the scissor bracket II are mutually closed while the scissor bracket II is unfolded, and the two clamping linkage arms are driven to mutually close, The clamping linkage arm pushes the packing box along with the L-shaped sliding frame, synchronously centers the packing box until the packing box is pushed away from the material placing roller frame along the material discharging roller frame, the material placing roller frame starts to descend through the ascending driving mechanism, at the moment, a single guide roller sleeved on the arc-shaped supporting block of the material placing roller frame descends along with the material placing roller frame, and pulls the arc-shaped supporting block and the telescopic arm to descend, so that the telescopic arm pulls the lower fixed rod to start rotating, the L-shaped linkage arm and the guide rod synchronously rotate, the guide rod pushes the second pushing sliding frame back to the original position on the linkage sliding table, the first shearing bracket and the second shearing bracket return to the original folding form, the L-shaped sliding frame for pushing the packing box to transport also withdraws along with the arc-shaped supporting block, After the material placing roller frame lifts a new packing box to the height of the external sliding frame again, the packing box with multi-stage distance is synchronously opened to transport and push materials, the transported packing box is synchronously opened to be centered in position, driving equipment is reduced, and meanwhile, transportation is enabled to follow synchronous operation of the packing lifting device.

The invention provides an automatic clamping and lifting device for a packing box. The beneficial effects are as follows:

1. The invention has the accurate synchronous transfer control effect: the transfer mechanism realizes accurate control of lifting height through the cooperation of a servo motor and a screw rod, realizes stable transfer of the packing box through the design of the extending linkage mechanism, realizes multistage push-out distance through the design of the scissor type support, enables the packing box to be effectively transferred at different heights, enhances the adaptability and flexibility of the system, realizes synchronous centering of the packing box through specific structural design (such as an L-shaped linkage arm and a guide rod) in the pushing process, and ensures the stability and accuracy in the transferring process.
