Description

Technical Field

[0001] The utility model relates to the technical field of unwinding devices, in particular to a cold-rolled coil unwinding device. Background Art

[0002] Cold-rolled coil is a coil produced by cold rolling process. The thickness is not more than 3mm for thin plate, and the thickness is more than 3mm for thick plate. In the production and processing of cold-rolled coil, an unwinding device is needed to unwind the cold-rolled coil.

[0003] For example, a unwinding device for cold-rolled stainless steel coil is disclosed in the patent with announcement number CN220277904U. Although the unwinding device can support one end of the winding roller by a movable plate to ensure the stability of the unwinding of the winding roller; however, before the unwinding device unwinds the cold-rolled coil, the operator needs to install the cold-rolled coil on the winding roller. However, the unwinding device needs to drive the nut to rotate by a rotating disc and push the movable plate to move so that it is separated from the threaded column, and the support of the movable plate on one end of the winding roller is released so that the cold-rolled coil can be installed on the winding roller. At the same time, after the cold-rolled coil is installed, the movable plate needs to be installed at one end of the winding roller. Therefore, the operation of installing the cold-rolled coil on the winding roller by the unwinding device is very inconvenient, so it needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0025] The following is combined with Figures 1 - 6 This embodiment is described in further detail.

[0026] like Figure 1 and Figure 2 As shown, a cold-rolled coil unwinding device in this embodiment includes a base 100 and support plates 110 relatively arranged on the base 100, a rotatable winding roller is arranged between the support plates 110, one of the two support plates 110 is movably arranged on the base 100 through a driving component, and the other is fixedly installed on the base 100, the winding roller includes a main roller 120 rotatably arranged on one of the two support plates 110 and an auxiliary roller 130 rotatably arranged on the other of the two support plates 110, the opposite ends of the main roller 120 and the auxiliary roller 130 can be butt-jointed, a butt-jointing component for fixing the auxiliary roller 130 is arranged in the main roller 120, and movable limit plates 140 are relatively arranged on the main roller 120 and the auxiliary roller 130.

[0027] In this embodiment, one end of the main roller 120 is rotatably mounted on the movable support plate 110 through a bearing, and one end of the auxiliary roller 130 is rotatably mounted on the fixed support plate 110 through a bearing. Among them, a motor 111 for driving the auxiliary roller 130 to rotate is mounted on the side surface of the fixed support plate 110. Thus, after the main roller 120 and the auxiliary roller 130 are butted, the motor 111 can drive the auxiliary roller 130 to rotate and drive the main roller 120 to rotate, realizing the rotational mounting of the winding roller between the support plates 110;

[0028] In this embodiment, the movement of the support plate 110 drives the main roller 120 to move towards the auxiliary roller 130, and the docking assembly is used to realize the docking between the two to form a winding roller. Thus, when the unwinding device installs the cold-rolled coil on the winding roller, first, the movement of the support plate 110 drives the main roller 120 to move away from the auxiliary roller 130. Then, the existing hoisting equipment is used to lift and move the cold-rolled coil, so that the auxiliary roller 130 is inserted into the cold-rolled coil. Then, the movement of the support plate 110 drives the main roller 120 to be inserted into the cold-rolled coil and be butted with the auxiliary roller 130. Thus, the installation of the cold-rolled coil on the winding roller is preferably realized. Compared with the existing ones, the installation of the cold-rolled coil on the winding roller in this embodiment is more convenient and beneficial for use;

[0029] In this embodiment, through the setting of the limiting disks 140, when the main roller 120 and the auxiliary roller 130 are butted to form a winding roller, the limiting disks 140 on both sides can limit the cold-rolled coil installed on the winding roller, thus facilitating the unwinding of the cold-rolled coil; among them, through the movable setting of the limiting disks 140, it can limit the cold-rolled coils with different widths installed on the winding roller, thus improving the applicability of the unwinding device.

[0030] Combined Figure 3 and Figure 4 As shown, in this embodiment, a square plug-in groove 311 is provided on the end wall of the main roller 120 corresponding to the auxiliary roller 130, and a plug-in block 410 that can be inserted into the plug-in groove 311 is provided on the end wall of the auxiliary roller 130. Opposite installation cavities 312 are provided in the main roller 120 on both sides of the plug-in groove 311; the docking assembly includes plug-in members that are opposite and telescopically arranged in the corresponding installation cavities 312. Opposite plug-in holes 411 are provided on the plug-in block 410, and the plug-in members penetrate through the installation cavities 312 and are inserted into the corresponding plug-in holes 411 to fix the plug-in block 410 in the plug-in groove 311.

[0031] In this embodiment, the shape of the plug-in block 410 is adapted to the plug-in groove 311. When the movement of the support plate 110 drives the main roller 120 to move and the plug-in block 410 is inserted into the plug-in groove 311, thus, the docking between the main roller 120 and the auxiliary roller 130 is preferably realized. At the same time, the rotation of the auxiliary roller 130 can drive the main roller 120 to rotate, realizing the rotation of the winding roller;

[0032] Among them, through the settings of the installation cavity 312, the plug-in parts and the plug-in holes 411, when the plug-in block 410 extends into the plug-in groove 311, the plug-in parts on both sides extend into the corresponding plug-in holes 411, so that the plug-in block 410 can be fixed, and it can be further fixed in the plug-in groove 311, improving the docking stability between the main roller 120 and the auxiliary roller 130.

[0033] In this embodiment, the plug-in part includes a sliding plate 320 arranged in the installation cavity 312 through a spring 310. A plug-in rod 321 that can extend into the plug-in groove 311 is arranged on the sliding plate 320. The spring 310 is used to push the sliding plates 320 closer to each other to insert the plug-in rod 321 into the corresponding plug-in holes 411. Inside the main roller 120 and between the installation cavities 312, there is a driving cavity 313, and a driving part for moving the sliding plates 320 away from each other to retract the plug-in rod 321 is arranged in the driving cavity 313.

[0034] During the actual use of this embodiment, in combination with Figure 3 As shown, the side wall of the sliding plate 320 is in sliding fit with the corresponding side wall of the installation cavity 312. At the same time, in order to improve the stable movement of the spring 310 to drive the sliding plate 320 in the installation cavity 312, two springs 310 are arranged oppositely in the installation cavity 312. Among them, in order to prevent the spring 310 from shifting and causing it to be unable to push the sliding plate 320 to move, a spring installation column is arranged on the side wall of the installation cavity 312. One end of the spring 310 is sleeved on the spring installation column, and the other end abuts against the corresponding sliding plate 320. Thus, preferably, the sliding plate 320 is stably slid in the installation cavity 312, and the sliding plates 320 on both sides are moved closer to each other, so that the plug-in rod 321 on it penetrates through the installation cavity 312 and extends into the plug-in groove 311, and the plug-in rod 321 can be kept extending into the plug-in hole 411 to fix the plug-in block 410;

[0035] Among them, through the settings of the driving cavity 313 and the driving part, the driving part can drive the sliding plates 320 on both sides to move away from each other, and then drive the plug-in rod 321 to retract into the corresponding installation cavity 312, so that the plug-in rod 321 disengages from the plug-in hole 411, releasing the fixation of the plug-in block 410, so as to separate the main roller 120 and the auxiliary roller 130 for the installation of the cold-rolled coil on the winding roller.

[0036] In combination with Figure 3 As shown, in this embodiment, sliding blocks 322 extending into the driving cavity 313 are arranged oppositely on the sliding plate 320, and arc-shaped inclined surfaces are arranged on the sliding blocks 322.

[0037] The driving member includes a driving column 330 slidably disposed in the driving cavity 313. An extrusion inclined surface 331 that cooperates with the arc-shaped inclined surface is provided on the side surface of the driving column 330 along its circumferential direction. A pull rod 332 that penetrates and extends out of the end of the main roller 120 away from the auxiliary roller 130 is further provided on the driving column 330. Pulling the pull rod 332 drives the driving column 330 to move, driving the extrusion inclined surface 331 to extrude the arc-shaped inclined surface, and realizing the mutual separation of the sliding blocks 322.

[0038] In the initial state of this embodiment, under the action of the spring 310, the sliding plates 320 are close to each other, which can drive the sliding blocks 322 to extend into the driving cavity 313, so that the arc-shaped inclined surface abuts against the extrusion inclined surface 331, and the driving column 330 moves towards the end of the driving cavity 313 close to the insertion slot 311. At this time, by pulling the extended end of the pull rod 332, the driving column 330 moves towards the end of the driving cavity 313 away from the insertion slot 311, so that the extrusion inclined surface 331 extrudes the arc-shaped inclined surface, driving the sliding blocks 322 to move away from each other, and then driving the sliding plates 320 to move away from each other, realizing the retraction of the insertion rod 321 into the installation cavity 312.

[0039] It should be noted that, in order to preferably realize the installation of the plug-in member and the driving member in the main roller 120, the main roller 120 in this embodiment is formed by splicing two half rollers.

[0040] During its actual use, in order to ensure that the insertion slot 311 is opposite to the insertion block 410 when the support plate 110 moves to drive the docking between the main roller 120 and the auxiliary roller 130, so that the insertion block 410 can extend into the insertion slot 311, in this embodiment, a cavity for the pull rod 332 to extend out is provided in the main roller 120. A chute is provided on the side wall of the cavity along its extending direction. A slider 333 that slides in the chute is provided on the outer side wall of the pull rod 332.

[0041] In this embodiment, by using the cooperation setting of the chute and the slider 333, a keyway fit is formed between the pull rod 332 and the main roller 120, so that rotating the pull rod 332 can drive the main roller 120 to rotate, and then the insertion slot 311 can be rotationally adjusted, which is convenient for the movable support plate 110 to drive the main roller 120 to move, and realizes the plug-in connection between the insertion block 410 and the insertion slot 311.

[0042] Among them, in order to facilitate the operator to drive the pull rod 332 to rotate, a hand crank wheel 334 is provided at the extended end of the pull rod 332.

[0043] Combined with Figure 5As shown in the figure, in this embodiment, an installation groove 101 is provided on the upper side surface of the base 100 in parallel with the axial direction of the winding roller. An installation rod is provided in the installation groove 101. One of the two support plates 110 is provided with an installation block 510 that extends into the corresponding installation groove 101 and slides therein. The installation rod passes through the corresponding installation block 510. The driving assembly includes a cylinder 150 provided on the base 100 and used to drive the corresponding support plate 110 to move.

[0044] In this embodiment, through the arrangement of the installation groove 101, the installation rod and the installation block 510, the installation rod passes through the installation block 510, so that the installation block 510 is slidably installed in the installation groove 101. Thus, preferably, the support plate 110 can be movably arranged on the base 100.

[0045] Among them, through the arrangement of the cylinder 150, it can preferably drive the support plate 110 to move on the base 100, making the docking between the main roller 120 and the auxiliary roller 130 more convenient.

[0046] Combined Figure 4 and Figure 5 As shown in the figure, in this embodiment, grooves 401 are provided on the outer side walls of the main roller 120 and the auxiliary roller 130 opposite to each other along their axial directions. The limiting disc 140 is provided with a limiting cylinder 610 sleeved outside the main roller 120 or the auxiliary roller 130. A hand-tightening bolt 620 that abuts against the bottom wall of the corresponding groove 401 is threadedly connected to the limiting cylinder 610.

[0047] Through the structure in this embodiment, in actual use, by turning the hand-tightening bolt 620 to squeeze the bottom wall of the groove 401, the limiting cylinder 610 can be fixed, that is, the limiting disc 140 is fixed. By loosening the hand-tightening bolt 620, the fixation of the limiting cylinder 610 is released, so that the limiting disc 140 can move on the winding roller, facilitating the movement adjustment of the limiting disc 140. Thus, the operation of moving and adjusting the limiting disc 140 is simple and convenient.

[0048] Working principle: First, pull the pull rod 332 outwards to retract the plug rod 321 into the installation cavity 312, releasing the fixation of the plug block 410. At this time, start the cylinder 150 to move the corresponding support plate 110, driving the main roller 120 away from the auxiliary roller 130. Then, use a hoisting device to lift and move the cold-rolled coil plate, so that the cold-rolled coil plate is sleeved on the auxiliary roller 130. Next, start the cylinder 150 to move the corresponding support plate 110, driving the main roller 120 towards the auxiliary roller 130, and pull the pull rod 332 outwards to retract the plug rod 321 into the installation cavity 312, enabling the plug block 410 to extend into the plug slot 311. Then, release the pull rod 332, allowing the spring 310 to drive the sliding plates 320 to approach each other, driving the plug rod 321 to extend into the corresponding plug holes 411, completing the docking between the main roller 120 and the auxiliary roller 130, and realizing the installation of the cold-rolled coil plate on the winding roller. After the installation of the cold-rolled coil plate is completed, loosen the hand-tightening bolt 620 to release the fixation of the limit disc 140, move the limit disc 140 to both ends of the cold-rolled coil plate, and fix the limit disc 140 by tightening the hand-tightening bolt 620 to limit the cold-rolled coil plate. At this time, drive the winding roller to rotate through the motor 111 to unwind the cold-rolled coil plate.
