[0022] Embodiments

[0023] Please refer to Figs. 1 to 3 The application embodiment provides a winding and unwinding module, which comprises a rack 1, a lead screw 2, a driving device 3, a plurality of inner wedge blocks 4 and outer wedge blocks 5. One end of the lead screw 2 is connected to the output end of the driving device 3, and the other end is rotatably arranged in the rack 1. When the lead screw 2 rotates, the side wall thereof can reciprocate along the axial direction thereof. The inner wedge block 4 and the outer wedge block 5 are both provided with an inclined slope surface. The inner wedge block 4 is arranged around the lead screw 2 and is fixed on the side wall of the lead screw 2, so that the inner wedge block 4 can move axially with the lead screw 2. The slope surface of the inner wedge block 4 is arranged along the axial direction of the lead screw 2 and faces the outer side of the lead screw 2. The outer wedge block 5 is slidably arranged beside the inner wedge block 4 along the radial direction of the lead screw 2, and the slope surface of the outer wedge block 5 is connected with the slope surface of the inner wedge block 4. At least one limiting rod 50 is arranged on the outer wedge block 5, one end of the limiting rod 50 is connected with the outer wedge block 5, and the other end is slidably connected with the rack 1. The sliding direction of the limiting rod 50 is along the radial direction of the lead screw 2.

[0024] In some embodiments, the winding and unwinding module of the application embodiment comprises four inner wedge blocks 4 and four outer wedge blocks 5 matched with the inner wedge blocks 4. The four inner wedge blocks 4 are arranged equidistantly around the side wall of the lead screw 2 to form a symmetrical cross-shaped support structure, thereby improving the overall stability.

[0025] Further, the winding and unwinding module further comprises a plurality of expansion plates 6, and the expansion plates 6 are respectively arranged on the outer side of the outer wedge block 5.

[0026] When the winding and unwinding module is working, the drive device 3 rotates, driving the lead screw 2 to rotate; the side wall of the lead screw 2 drives the inner wedge block 4 to move along the axial direction of the lead screw 2. Since the inclined surface of the inner wedge block 4 is connected to the inclined surface of the outer wedge block 5, when the inner wedge block 4 moves along the axial direction of the lead screw 2, it will exert an outward force on the outer wedge block 5, causing the outer wedge block 5 to move radially along the lead screw 2, so that the expansion and contraction plate 6 opens to clamp the roll material or contracts to release the roll material. During the opening process of the expansion and contraction plate 6 and after clamping the roll material, the limiting rod 50 can stabilize the outer wedge block 5, prevent the outer wedge block 5 from being deviated by external forces, and improve the stability of winding and unwinding.

[0027] In some embodiments, the frame 1 includes a base plate 101 and a sleeve 102. A lead screw 2 is vertically mounted on the base plate 101, and the sleeve 102 is fitted with the lead screw 2. The sleeve 102 has a wedge-shaped block through hole that mates with an outer wedge-shaped block 5, and the outer wedge-shaped block 5 is telescopically inserted into the wedge-shaped block through hole. The base plate 101 has a plurality of sliding grooves corresponding one-to-one with the outer wedge-shaped blocks 5, and the sliding grooves are arranged parallel to the radial direction of the lead screw 2; one end of a limiting rod 50 is connected to the outer wedge-shaped block 5, and the other end is slidably inserted into the sliding groove.

[0028] Further, the limiting rod 50 includes a rod body 501 and a pulley 502. One end of the rod body 501 is connected to the outer wedge block 5, and the other end passes through the sliding groove and protrudes from the other side of the base plate 101; the pulley 502 is disposed on the end of the rod body 501 protruding from the base plate 101 and abuts against the base plate 101. When the limiting rod 50 slides in the sliding groove, the pulley 502 can reduce the friction between the limiting rod 50 and the base plate 101. Preferably, the limiting rod 50 includes two pulleys 502, which are symmetrically disposed on both sides of the end of the rod body 501 protruding from the base plate 101. Further, the sliding direction of the pulleys 502 is parallel to the sliding groove. When the inner wedge block 4 moves along the axial direction of the lead screw 2, its thrust on the outer wedge block 5 exists not only in the radial direction of the lead screw but also in the axial direction. The limiting rod 50 can counteract this axial force, preventing the outer wedge block 5 from moving along the axial direction of the lead screw 2, thereby limiting the outer wedge block 5.

[0029] The winding and unwinding module of this application limits the outer wedge block 5 with the limiting rod 50 to prevent the outer wedge block 5 from shifting due to external force under the pressure of the roll material and when the winding and unwinding module is working; thereby improving the stability of the expansion and contraction plate 6, and thus improving the load-bearing capacity and stability of the winding and unwinding module.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
