Referring to fig. 1 to 3, the core of the present invention is to provide a variable diameter unwinding mechanism, which includes a guide rod 9, two side guards 5, a lead screw 8, a connecting seat 7 and a plurality of expansion plates 6. Make the rotation of lead screw 8 through adjusting device, the rotation of lead screw 8 drives connecting seat 7 and slides on guide bar 9, and connecting seat 7 drives connecting rod 10 and removes, and connecting rod 10 drives bloated tight board 6 and is close to or keep away from guide bar 9 and remove to the diameter of the circle of 6 constitutions of a plurality of bloated tight boards is adjusted in the realization. Through regarding guide bar 9 as center pin and bearing structure, lead screw 8 is as the structure of adjusting the tight board 6 position that expands for whole unwinding mechanism's bearing capacity is stronger. Because if the lead screw 8 is used as a bearing structure, the lead screw 8 is easy to bend, and the guide rod 9 has stronger bearing capacity.
The guide rod 9 is made by high strength material, and its both ends link firmly in the frame, and the frame comprises two triangle-shaped supports 4, and the cover is equipped with two side shield 5 on the guide rod 9, and side shield 5 is preferably the plectane, and side shield 5 passes through the bearing and rotates to be connected in guide rod 9, that is to say that side shield 5 uses guide rod 9 to rotate as the frame relatively of center pin.
The two ends of the screw 8 are respectively connected to the two side baffles in a rotating manner, and the screw 8 is located on one side of the guide rod 9 and is parallel to the guide rod, that is, the screw 8 is eccentrically arranged. The lead screw 8 is connected with the guide rod 9 through the connecting seat 7, the connecting seat 7 is a non-standard special-shaped nut, one end of the connecting seat is provided with a threaded hole, the other end of the connecting seat is provided with a through hole, one end of the threaded hole of the connecting seat 7 is sleeved with the lead screw 8 and is in threaded connection with the lead screw, and one end of the through hole of the connecting seat 7 is sleeved with the guide rod 9 and is in sliding. The screw 8 can rotate or not rotate through an adjusting device, and the connecting seat 7 is driven to slide on the guide rod 9 when the screw rotates.
The tight board 6 that expands has threely in this embodiment to guide bar 9 is the circumference equipartition of center pin, and the tight board 6 that expands is the circular arc board, and a circle is constituteed to the tight board 6 that expands three, and the coiled material just overlaps and locates on the circle of constituteing by three tight board 6 that expands.
The radial sliding connection in two side shields 5 of guide bar 9 is followed respectively at the both ends of tight board 6 that expands, and is concrete, has all seted up a plurality of mounting grooves on two side shields 5, and the mounting groove be equipped with 9 vertically slide bars of guide bar, and the slide bar extension line intersects with guide bar 9, has seted up the through-hole on the tight board 6 that expands, 6 covers of tight board that expand through this through-hole are established and sliding connection in slide bar.
The expansion plate 6 is connected with the connecting seat 7 through a connecting rod 10, and two ends of the connecting rod 10 are respectively hinged to the expansion plate 6 and the connecting seat 7. Specifically, two flanges are arranged on the expansion plate 6 and the connecting seat 7 at the hinged position, the connecting rod 10 is arranged between the two flanges, the two flanges and the connecting rod 10 are connected in series through a hinged rod, the hinging is realized, and the hinged rod is vertical to the guide rod 9. When connecting seat 7 slides on guide bar 9, drive connecting rod 10 and rotate at two pin joints, connecting rod 10 drives bloated tight board 6 and draws in or disperse, is also close to or keeps away from guide bar 9 and removes to this diameter that the realization changes the circle that is used for bearing the coiled material that comprises three bloated tight board 6.
Specifically, adjusting device includes first gear 1 and second gear 3, and first gear 1 cover is established and is rotated and connect in guide bar 9, and is located between the side shield 5 and the support 4 of one side, and first gear 1 passes through drive arrangement drive in order to rotate.
