[0026] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, the steel sheet coil is first unrolled from a steel sheet coil unwinding tool 1 of the utility model, and then transferred to the guide mechanism 3 through the transition mechanism 2 of the steel sheet transmission, and finally the guide mechanism 3 guides the steel sheet to be transferred to the target steel pipe manufacturing equipment.

[0028] like Figure 2-3 As shown, a steel sheet roll unwinding tool of the utility model comprises an unwinding disc 11, a cylinder 12, a steel sheet roll positioning mechanism 13, and a driven rod 14; the unwinding disc 11 is provided with a load-bearing rod 15 and a through hole 113, one end of the driven rod 14 is connected to the cylinder 12, the other end of the driven rod 14 passes through the through hole 113, the driven rod 14 is provided with a connecting hole 141 along the axis, and the load-bearing rod 15 is located in the connecting hole 141;

[0029] like Figure 4-5 As shown, the steel sheet roll positioning mechanism 13 includes a fixed block 131 and a plurality of steel sheet roll support rods 132; the fixed block 131 is coaxially fixed to the driven rod 14, the plurality of steel sheet roll support rods 132 are hinged to the fixed block 131, and the steel sheet roll support rods 132 are vertically provided with steel sheet roll positioning rods 133;

[0030] The load-bearing rod 15 supports the weight of the steel sheet roll positioning mechanism 13, strengthens the connection strength and stability of the steel sheet roll positioning mechanism 13 during operation, and enables the steel sheet roll positioning mechanism 13 to stably support the steel sheet roll 4. At the same time, the load-bearing rod 15 also guides the reciprocating movement of the driven rod 14 to prevent the travel direction of the driven rod 14 from deviating.

[0031] The number of steel sheet roll support rods 132 is preferably four, and the four steel sheet roll support rods 132 are hinged on the fixed block 131 in a circular array. Figure 4 As shown, the four steel sheet roll support rods 132 form a four-claw support structure, which has the best supporting performance for the inner wall of the steel sheet roll 4 and can stably support the steel sheet roll 4 to prevent the steel sheet rolled inside the steel sheet roll 4 from being crushed due to the inner wall of the steel sheet roll 4 being squeezed inward when the steel sheet roll 4 is unrolled, thereby affecting the subsequent production quality of the steel pipe.

[0032] like Figure 6As shown, the steel sheet roll support rod 132 includes a connecting arm 1321 and a support plate 1322. The support plate 1322 is hinged to the fixed block 131 through the connecting arm 1321, and the two sides of the support plate 1322 are inclined downward. The two sides of the support plate 1322 are inclined downward, and the steel sheet roll support rod 132 is an umbrella-shaped structure as a whole. The top of the support plate 1322 is more in line with the arc surface of the inner wall of the steel sheet roll 4, which enhances the support capacity of the steel sheet roll support rod 132 to the steel sheet roll 4, and reduces the pressure between the side of the support plate 1322 and the inner wall of the steel sheet roll 4, preventing the edge of the support plate 1322 from crushing the steel sheet.

[0033] The unwinding disc 11 is provided with a plurality of slide grooves 112, and the slotting position of each slide groove 112 is adapted to the position of the steel sheet coil support rod 132; the end of the steel sheet coil support rod 132 is provided with a sliding guide 16, such as Figure 7-8 As shown, rollers 161 are provided at both ends of the sliding guide 16, and the sliding guide 16 passes through the slide groove 112, and the rollers 161 at both ends of the sliding guide 16 are respectively close to the two side walls of the unwinding disk 11. The steel sheet coil support rod 132 can move along the slide groove 112 through the sliding guide 16, and the rollers 161 roll against the unwinding disk 11, so that the steel sheet coil support rod 132 and the unwinding disk 11 have rolling friction, and the movement is smoother and faster.

[0034] The utility model provides a steel sheet roll unwinding tool. Before the steel sheet roll 4 is inserted, the piston rod of the cylinder 12 is extended, and the driven rod 14 moves along the load-bearing rod 15 toward the unwinding disk 11, and the fixed block 131 fixed to the driven rod 14 moves forward accordingly, and the steel sheet roll support rods 132 hinged thereto gather inward, so that the steel sheet roll 4 is conveniently inserted on the steel sheet roll support rods 132; then, the piston rod of the cylinder 12 retracts, the driven rod 14 moves back along the load-bearing rod 15, and the steel sheet roll support rods 132 hinged to the fixed block 131 expand outward to support the inner wall of the steel sheet roll 4; the steel sheet roll 4 is positioned between the steel sheet roll positioning rod 133 and the unwinding disk 11 for unwinding the steel sheet.

[0035] The steel sheet roll positioning rod 133 is detachably connected to the top of the steel sheet roll support rod 132 through a fastener 135. The fastener 135 may be a fastening screw, and a threaded hole is provided at the top of the steel sheet roll positioning rod 133. The fastening screw passes through the threaded hole and abuts against the top of the steel sheet roll support rod 132. According to the steel sheet rolls of different widths, the spacing between the steel sheet roll positioning rod 133 and the unwinding disk 11 is adjusted through the fastener 135 to improve the positioning adaptability of the steel sheet roll positioning rod 133 to the steel sheet roll.

[0036] The steel sheet roll positioning rod 133 is provided with a plurality of weight-reducing holes 134. The weight-reducing holes 134 reduce the overall weight of the steel sheet roll positioning rod 133, reduce the burden of the load-bearing rod 15, and improve the stability of the movement of the steel sheet roll support rod 132.

[0037] like Fig. 9As shown, a material support guide 17 is provided between the unwinding disk 11 and the cylinder 12 , and the material support guide 17 includes a connecting plate 171 and a guide shaft 172 . The guide shaft 172 is fixed on the connecting plate 171 , and the driven rod 14 passes through the guide shaft 172 and is connected to the unwinding disk 11 .

[0038] Since the steel sheet roll 4 and the steel sheet roll positioning mechanism 13 are heavy during the actual material support, the driven rod 14 at one end of the steel sheet roll is subjected to greater force, and the driven rod 14 located at the through hole 113 is a force point, and the driven rod 14 is at risk of breaking at this force point. On the basis of the load-bearing and guiding function of the load-bearing rod 15, the material support guide 17 not only guides the driven rod 14, but also further enhances the connection strength of the driven rod 14.

[0039] A plurality of balancing arms 111 extend outward from the outer wall of the unwinding disc 11. The balancing arms 111 balance the unwinding disc 11 of the disc structure, and reduce the shaking degree of the unwinding disc 11 during unwinding.

[0040] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all within the scope defined by the claims of this application.
