[0002] Strip-shaped coils, such as steel strips, are one of the commonly used coils in automated production lines. Since the strip-shaped coils are long, they need to be wound on a circular material tray. When in use, the circular material tray is slowly rotated to gradually unroll the strip-shaped coil.

[0003] For example, the Chinese invention with the announcement number CN113877985A discloses "a steel strip unwinding machine with stable unwinding", which includes a support base, on which a coil changing assembly is arranged, including a material changing disk rotatably arranged on the support base, and a first driving mechanism for driving the material changing disk to rotate is arranged on the support base; a tightening assembly includes two turntables rotatably arranged on the material changing disk, a plurality of support plates are slidably arranged on the turntable, a bidirectional screw is rotatably arranged in the middle of the turntable, and two sleeves that slide synchronously in opposite directions or opposite directions are threadedly connected on the bidirectional screw, a plurality of connecting rods that are hingedly arranged on the sleeves and cooperate with the support plates are hingedly arranged, and a second driving mechanism for driving the bidirectional screw to rotate in one direction is arranged on the support base.

[0004] Although the device drives the two sleeves to synchronously support the connecting rod through a bidirectional screw to ensure that the support plate is evenly stressed to tighten the steel strip coil, during the unwinding process, the expansion and contraction reel needs to bear the weight of the steel coil, which will affect the unwinding stability during the unwinding process. The long-term load-bearing work of the expansion and contraction reel will cause serious wear to it. Summary of the invention

[0024] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figures 1 to 6 As shown, an embodiment of the present invention proposes a new type of steel coil unwinding machine, including a support seat 1, with supporting feet provided at the four corners of the bottom, and multiple groups of load-bearing rollers 101 rotatably arranged thereon; a movable part, including a travel seat 2 slidably arranged on the support seat 1, and a driving source 203 arranged on the travel seat 2, the output end of the driving source 203 is connected to a expansion and contraction reel 204, the expansion and contraction reel 204 is located on the upper side of the multiple groups of load-bearing rollers 101, and is used to install a steel coil body 100; a limiting assembly, including a cantilever 4 rotatably arranged on the travel seat 2 through a limiting unit, and a limiting mechanism arranged on the cantilever 4, the limiting mechanism is used to be clamped on both sides of the steel coil body 100; a lifting mechanism, including a lifting member arranged on the support seat 1 for lifting the movable part, and a braking member arranged on the support seat 1 for limiting the rotation of the lifting member, and the lifting mechanism is located on the upper side of the driving source 203.

[0026] The detailed working process of this embodiment is as follows: multiple groups of load-bearing rollers 101 are used to place the steel coil body 100, the driving source 203 is used to drive the expansion and contraction reel 204 to rotate, the expansion and contraction reel 204 is used to install the steel coil body 100, and the limiting unit is used to limit the position of the cantilever 4.

[0027] The steel coil is supported by multiple groups of load-bearing rollers 101 arranged on the support seat 1, which prevents the expansion and contraction reel 204 from bearing all the weight of the steel coil. The rotation arrangement of the multiple groups of load-bearing rollers 101 can reduce the friction during the rotation of the steel coil, and can effectively improve the stability of the driving source 203 driving the steel coil to rotate. At the same time, the steel coil is placed on the multiple groups of load-bearing rollers 101 to restrict itself, which prevents the steel coil from dispersing due to its own elastic force during the uncoiling process. At the same time, with the setting of the limiting mechanism, the steel coil sheet can be prevented from slipping sideways during the uncoiling process.

[0028] The driving source 203 in this embodiment is a motor. In other embodiments, a desired driving device can be selected according to actual conditions.

[0029] like Figure 2 As shown, limit blocks 201 are arranged on both sides of the travel seat 2, a travel groove 102 is opened on the support seat 1, and limit grooves 103 are opened on both side walls of the travel groove 102, wherein the travel seat 2 is located in the travel groove 102, and each limit block 201 is located in the corresponding limit groove 103, and a mounting plate 202 is arranged on the side of the travel seat 2 away from the load-bearing roller 101, and the driving source 203 is arranged on the mounting plate 202, and the expansion and contraction reel 204 passes through the travel seat 2 and is connected to the output end of the driving source 203.

[0030] The detailed working process of this embodiment is as follows: the travel seat 2 can slide in the travel groove 102 under the setting of the limit block 201, the driving source 203 is set on the mounting plate 202, the driving source 203 and the expansion and contraction reel 204 move with the travel seat 2, and during the unwinding process, the position of the travel groove 102 decreases as the steel coil decreases.

[0031] like Figure 2 and Figure 5 As shown, the travel seat 2 is provided with a support arm 205 , and a stepped shaft 402 is fixedly provided at one end of the cantilever 4 , and the stepped shaft 402 is rotatably provided at one end of the support arm 205 away from the travel seat 2 .

[0032] like Figure 6As shown, the limiting unit includes a clamping shaft 5 movably arranged in the support arm 205, a limiting ring 503 fixedly arranged on the clamping shaft 5, and a reset spring 501 sleeved on the clamping shaft 5, a receiving groove 206 is opened in the support arm 205, the limiting ring 503 and the reset spring 501 are both located in the receiving groove 206, two clamping grooves 406 are opened on the stepped shaft 402, and the two clamping grooves 406 form an angle of ninety degrees, wherein the clamping shaft 5 is clamped in any one of the clamping grooves 406 under the elastic force of the reset spring 501.

[0033] The detailed working process of this embodiment is as follows: the stepped shaft 402 is rotatably set on the support arm 205, so that the cantilever 4 can rotate around the axis of the stepped shaft 402, and the rotation position of the cantilever 4 is controlled by setting the clamping shaft 5 and the two sets of clamping slots 406, so that the cantilever 4 can be divided into a working state and a non-working state. The working principle of the clamping shaft 5 is that under normal conditions, the clamping shaft 5 is clamped in any clamping slot 406 under the elastic force of the reset spring 501. At this time, the rotational freedom of the cantilever 4 is limited by the clamping shaft 5. If it is in the non-working state at this time, the limiting mechanism is for the steel coil, which is convenient for installing the steel coil. When it needs to be adjusted to the working state, it only needs to lift the clamping shaft 5 to disengage it from the clamping slot 406, and then the cantilever 4 can be rotated for adjustment.

[0034] During the working process, the cantilever 4 can be divided into a working state and a non-working state. In the working state, the limiting mechanism on the cantilever 4 clamps the steel coil to prevent the steel coil from slipping sideways during the unwinding process. In the non-working state, the limiting mechanism clamps the steel coil to facilitate the installation of the steel coil.

[0035] like Figure 5 As shown, an arc groove 407 is provided on the cantilever 4, and the limiting mechanism includes a stud 403 rotatably set in the arc groove 407 and two mounting blocks 404 threadedly connected to the stud 403, and each mounting block 404 is provided with a limiting roller 401.

[0036] The detailed working process of this embodiment is as follows: the function of the stud 403 is to control the two limit rollers 401 to move away from or close to each other. When in use, after the steel coil is installed on the expansion and contraction reel 204, the cantilever 4 is rotated to adjust the two limit rollers 401 to the two sides of the steel coil, and then the two limit rollers 401 are adjusted by rotating the stud 403 to make them abut against the steel coil to prevent the steel coil from slipping sideways during the unwinding process. At the same time, the limit rollers 401 can also rotate during the unwinding and rotation process of the steel coil to avoid wear on the side edges of the steel coil.

[0037] like Figure 3 and Figure 4 As shown, the lifting member includes a wire twisting roller 3 rotatably arranged on a support seat 1 , a steel cable 301 is arranged on the wire twisting roller 3 , and one end of the steel cable 301 is connected to the mounting plate 202 .

[0038] The detailed working process of this embodiment is as follows: the function of the stranding roller 3 is to lift the travel seat 2 through the steel cable 301, so that the axis of the expansion and contraction drum 204 overlaps with the axis of the steel coil, which is convenient for installing the steel coil. When the expansion and contraction drum 204 needs to be lifted, the stranding roller 3 can be rotated.

[0039] like Figure 3 and Figure 4 As shown, the braking member includes a ratchet 302 arranged on the wire twisting roller 3, and two ratchets 303 movably arranged on the support seat 1, each ratchet 303 is provided with a compression spring 306, and each ratchet 303 is clamped on the ratchet 302 under the elastic force of the compression spring 306, wherein an adjustment block 304 is rotatably arranged between the two ratchets 303, and the adjustment block 304 abuts against any one of the ratchets 303.

[0040] The detailed working process of this embodiment is as follows: under the setting of the ratchet 302 and the ratchet teeth 303, the wire stranding roller 3 can be restricted to prevent it from rotating in the opposite direction due to gravity, causing the expansion and contraction drum 204 to fall and affecting the installation of the steel coil. In any case, only one ratchet tooth 303 abuts against the ratchet 302 to limit the clockwise or counterclockwise rotation of the ratchet 302. The function of the adjustment block 304 is to adjust the state of the two ratchet teeth 303. In any case, the adjustment block 304 abuts against only one ratchet tooth 303, and the ratchet tooth 303 abutting against it is away from the ratchet 302 and does not participate in the restriction. In actual operation, the adjustment block 304 can be controlled according to actual needs.

[0041] like Figure 2 As shown, each load-bearing roller 101 is provided with a rubber pad 104 .

[0042] The detailed working process of this embodiment is as follows: the function of the rubber pad 104 is to prevent the load-bearing roller 101 from directly and rigidly contacting the steel coil and causing scratches on the steel coil.

[0043] like Figure 5 As shown, a rocker 405 is provided at one end of the stud 403.

[0044] The detailed working process of this embodiment is as follows: the function of the rocker 405 is to facilitate the rotation of the stud 403 .

[0045] like Figure 5 As shown, the end of the card shaft 5 inserted into the card slot 406 is in an arc surface.

[0046] The detailed working process of this embodiment is as follows: the arc surface at one end of the clamping shaft 5 can directly push the clamping shaft 5 out of the clamping slot 406 when the cantilever 4 is rotated in the reverse direction, thereby improving the rotation efficiency.

[0047] The implementation principle of the embodiment of the present application is: first, the height of the expansion and contraction drum 204 is adjusted by rotating the stranding roller 3 so that the axis of the expansion and contraction drum 204 overlaps with the axis of the steel coil, and then the steel coil is installed on the expansion and contraction drum 204. The steel coil is located on multiple groups of load-bearing rollers 101 under its own gravity. After the installation is completed, the cantilever 4 is rotated to adjust the two limit rollers 401 to the two sides of the steel coil, and then the two limit rollers 401 are adjusted by rotating the stud 403 to make them abut against the steel coil.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
