The support comprises a lifting bottom plate 14, the hook material translation module is installed on the lifting bottom plate 14, the lifting bottom plate 14 is thin and is not convenient to be connected with the lifting module 10, therefore, the lifting bottom plate 14 is connected with the lifting module 10 through a slider fixing plate 15 fixed on one side, and a bottom plate reinforcing rib 16 is arranged between the lower portion of the lifting bottom plate 14 and the slider fixing plate 15 to ensure the connection stability of the lifting bottom plate 14 and the slider fixing plate 15. In order to further reduce the stress of the lifting module 10, a hollow-out groove 17 is formed in the lifting bottom plate 14, and the hook component 20 is mounted on the lifting bottom plate 14 through a suspension plate 25. On the one hand, the weight of the lifting bottom plate 14 is reduced, and on the other hand, the hook material assembly 20 forms a module which, when it fails, facilitates the removal of the whole for maintenance.

Referring to fig. 3, in this embodiment, the hooking translation module includes a first-stage translation module 23 and a second-stage translation module 24, the first-stage translation module 23 is installed on the bracket, the second-stage translation module 24 is connected to the first-stage translation module 23, and the mounting plate 21 is connected to the second-stage translation module 24. The primary translation module 23 corresponds to the size of the support, which, because of its connection to the lifting module 10, usually occupies a large space and cannot be inserted below the material frame. Consequently, set up second grade translation module 24, second grade translation module 24 stretches out the scope of support under the drive of one-level translation module 23, and its shared space is less, does not influence and inserts the material frame below, and when second grade translation module 24 withdrawed, directly supports by support and one-level translation module 23 jointly, guarantees to bear the stability of supporting when expecting the frame. Further, one-level translation module 23 is a lead screw linear module, and includes lead screw mount pad 231, lead screw body 232, screw nut 233, lead screw motor 234 and one-level linear guide 235, lead screw body 232 both ends pass through the bearing with lead screw mount pad 231 rotates to be connected, one-level linear guide 235 parallel arrangement in lead screw body 232 side, screw motor 234 drive lead screw body 232 is rotatory, screw nut 233 overlaps and locates on lead screw body 232, second grade translation module 24 is connected screw nut 233 and one-level linear guide 235. The lead screw motor 234 drives the lead screw body 232 to rotate, and the lead screw nut 233 connected with the second-stage translation module 24 cannot rotate, so that the second-stage translation module 24 is driven to move along the axial movement of the lead screw body 232, and the second-stage translation module 24 is also connected with the first-stage linear guide 235, so that the movement stability of the second-stage translation module can be ensured. The driving force of the screw rod linear module is large, and even if the material frame is filled with materials, the material frame can be pulled by the push-pull block 22.

Therefore, when the material frame is pulled out of the wire body by the push-pull block 22, the material frame directly moves to the chain 33 from the wire body, namely the material frame is supported by the supporting side plate 31 and the supporting block 32, so that no pressure is applied to the secondary translation module 24, and the service life of the material hooking component 20 is prolonged. And because the chain 33 is arranged, the friction force is small when the material frame moves above the bracket, and the pushing of the material frame by the push-pull block 22 is not influenced. Further, when the material frame moves on the chain 33, the material frame is prone to skew due to the fact that the left and the right are not limited, if the baffle plates are directly arranged on the two sides of the chain 33, friction exists between the material frame and the baffle plates, and movement of the material frame is affected. Therefore, a guide wheel fixing plate 34 is disposed on the top of the supporting side plate 31, and a plurality of guide rollers 35 are rotatably connected to the guide wheel fixing plate 34. The guide wheel fixing plate 34 limits the deviation of the material frame, and the guide roller 35 ensures that the material frame can move smoothly.

If the material frame is located on the transferring mechanism, the lifting module 10 is driven by a mechanical arm or other transferring module to move to the position of the material hooking component 20 corresponding to the line. The first-stage translation module 23 and the second-stage translation module 24 are pushed out to push the material frame from the chain 33 to the line body, the lifting module 10 drives the hooking component 20 to descend, the push-pull plate is pulled out of the material frame, the first-stage translation module 23 and the second-stage translation module 24 are retracted, and the material frame is transferred from the transfer mechanism to the line body.
