Description

Technical Field

[0001] This utility model relates to the field of unwinding equipment technology, specifically an automatic centering unwinding machine. Background Technology

[0002] An uncoiler is a specialized piece of equipment for leveling metal sheets. It's used to level steel plates and uneven plates, and can be configured to form uncoiler, leveling, and shearing production lines, as well as other sheet metal product production lines. It's suitable for industries such as machinery, vehicles, metal products, household appliances, steel structures, and decoration. The uncoiler is an essential piece of equipment in welded pipe production lines. Its functions are twofold: first, to support the steel coil by tightening its inner hole; and second, to feed the end of the steel strip into the leveling machine through rotation in conjunction with a straightening machine. However, when placing the steel coil on the uncoiler, its position is usually observed and adjusted manually, which can easily lead to deviations. Furthermore, during release, the steel coil can easily droop to the ground, and the leveling machine pulls and moves one end of the coil, causing friction between the coil and the ground, resulting in scratches and affecting product quality.

[0041] Please see Figure 1-6 In this embodiment of the present invention, the automatic centering and uncoiling machine includes: a support plate 100, a centering mechanism 200, and a guiding mechanism 300. A circular hole 101 is provided on one side of the support plate 100, a rectangular hole 102 is provided at one end of one side of the support plate 100, and a sliding through hole 103 is provided at the other end of one side of the support plate 100. A rotating shell 120 is rotatably connected inside the circular hole 101, and a circular shell 110 is fixedly connected inside the rotating shell 120. Multiple connecting holes 111 are provided at both ends of the outer side wall of the circular shell 110. A support component is provided on the circular shell 110. The centering mechanism 200 is fixed to one end inside the support plate 100, and the guiding mechanism 300 is fixed to the other end inside the support plate 100.

[0042] Specifically, the load-bearing components facilitate the placement and support of the roll material, and are applicable to roll materials of different sizes. The centering mechanism 200 can push the roll material for centering, and the guiding mechanism 300 facilitates the support and guidance of the released roll material, making it more convenient to use.

[0043] Example 1

[0044] like Figure 5As shown, in this embodiment, the centering mechanism 200 includes: a fixing block 210 and a U-shaped plate 220. One end of the fixing block 210 is fixedly connected to one side of the bearing plate 100. A hydraulic cylinder 211 is fixedly connected to one side of the fixing block 210, and a convex block 212 is fixedly connected to the output end of the hydraulic cylinder 211. One end of the convex block 212 is slidably connected to the interior of the rectangular hole 102. The U-shaped plate 220 is fixedly connected to one end of the convex block 212.

One end of each movable seat 240 is slidably connected to the interior of two connecting holes 221. One end of each movable seat 240 is fixedly connected to the push plate 230 at the corresponding position. One end of the second hydraulic cylinder 250 is fixedly connected to one side of the C-shaped plate 220. The output end of the second hydraulic cylinder 250 is fixedly connected to the C-shaped block 251. Both ends of the C-shaped block 251 are provided with connecting notches 252. The interior of the connecting notches 252 is rotatably connected to the connecting plate 253. One end of the connecting plate 253 is rotatably connected to the interior of the movable seat 240 at the corresponding position. One side of the C-shaped plate 220 is fixedly connected to a rectangular frame 260. The outside of the rectangular frame 260 is slidably connected to a fixed shell 270. One end of the fixed shell 270 is fixedly connected to one side of the bearing plate 100.

[0045] In this embodiment, by activating hydraulic cylinder 211, the convex block 212 and the U-shaped plate 220 are moved to the appropriate position, thereby causing the two push plates 230 to move to both ends of the roll material. By activating hydraulic cylinder 250, the U-shaped block 251 is moved, thereby causing the other ends of the two connecting plates 253 to move. The moving connecting plates 253 pull the moving seat 240 and the push plates 230 to move. The two moving push plates 230 facilitate the movement of the roll material, thereby enabling the roll material on the outer side of the circular shell 110 to be automatically centered.

[0046] like Figure 3-4As shown, in this embodiment, the supporting assembly includes: a motor 130, multiple support plates 140, a bidirectional lead screw 150, two moving blocks 160, and multiple limiting rods 170. The motor 130 is fixedly connected to one end of the circular shell 110. The output end of the motor 130 passes through the side wall of the circular shell 110 and is fixedly connected to a rotating rod 131. The multiple support plates 140 are evenly arranged on the outer side of the circular shell 110. The inner side wall of the support plate 140 has a placement notch 141. The bidirectional lead screw 150 is sleeved and fixed to the outer side of the rotating rod 131. The two moving blocks 160 are respectively screwed into the two ends of the bidirectional lead screw 150. The movable block 160 is provided with multiple limiting notches 161. Multiple rotating seats 162 are uniformly fixed to the outer side of the movable block 160. A support rod 163 is rotatably connected inside the rotating seat 162. A rotating seat 2 164 is rotatably connected to the outer side of one end of the support rod 163. One end of the rotating seat 2 164 is fixed to an inner side wall of a notch 141 at a corresponding position. The support rod 163 is slidably connected to a connecting hole 111 at a corresponding position. Multiple limiting rods 170 are fixed inside the round shell 110. The limiting rods 170 are slidably connected to the limiting notches 161 at corresponding positions.

[0047] In specific implementation, by starting motor 130, the rotating rod 131 and the bidirectional lead screw 150 are rotated, thereby causing the two moving blocks 160 to move. The moving blocks 160 push multiple rotating seats 162 to move, and the movement of the rotating seats 162 can push the other end of the support rod 163 to move, thereby causing multiple support rods 163 to rotate synchronously. The deflection of multiple support rods 163 causes multiple rotating seats 164 to move to the appropriate position, thereby causing multiple support plates 140 to move to the appropriate position. The multiple support plates 140 are used to facilitate the support and fixation of the roll material, and by adjusting the position of the multiple support plates 140, the load-bearing component can be adapted to roll materials of different sizes.

[0048] Example 2

[0049] Based on Example 1, in order to facilitate the guidance of the released roll material and prevent it from falling to the ground and rubbing against the ground during transportation, which would cause wear and tear on the roll material and affect product quality.

[0050] like Figure 6As shown, in this embodiment, the guiding mechanism 300 includes: a rotating plate 310, a support shell 320, and two guide rollers 330. One end of the rotating plate 310 has a rotating hole 311, which is rotatably connected to the outer wall of the rotating shell 120. An adjusting assembly is provided on one side of the rotating plate 310. One end of the support shell 320 is fixedly connected to one side of the rotating plate 310. Both guide rollers 330 are rotatably connected to the interior of the support shell 320. The adjusting assembly includes: a round block 340, an oil... Cylinder 350 and connecting block 360, one end of round block 340 is rotatably connected to the other side of bearing plate 100, rotating block 341 is rotatably sleeved on the outer side of round block 340, one end of cylinder 350 is fixedly connected to one end of rotating block 341, connecting block 360 is fixedly connected to the output end of cylinder 350, traction block 361 is fixedly connected to one side of connecting block 360, and one end of traction block 361 is rotatably connected to one side of rotating plate 310, and traction block 361 is slidably connected to the inside of sliding through hole 103.

[0051] In practice, by activating the hydraulic cylinder 350, the connecting block 360 and the traction block 361 are moved, thereby causing the rotating plate 310 to deflect. This, in turn, moves the support shell 320 and the two guide rollers 330 to the appropriate positions. The two guide rollers 330 are used to support and guide the released roll material, thus preventing the released roll material from falling to the ground and rubbing against the ground during transportation, which would cause wear and affect product quality.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0053] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
