CONTENT OF UTILITY MODEL

[0003] The utility model aims at overcoming the shortcomings in the prior art, providing a slitting machine unwinding steel core bracket device which can push the steel core to the position of specified chuck and automatically push out the empty steel core when changing roll, greatly reducing the dependence on manpower, thereby improving production efficiency and reducing labor intensity.

[0004] The technical scheme of the utility model is:

[0005] A slitting machine unwinding steel core bracket device, comprising:

[0006] The steel core bracket is provided with guide rails for supporting the steel core, and the steel core bracket is provided with limiting blocks and feeding blocks distributed along the direction of the guide rails, the side of the feeding block facing the limiting block is provided with a guide slope, and the upper part of the guide slope is inclined away from the limiting block;

[0007] The fork mechanism comprises a fork rotatably arranged on the steel core bracket and a rotary drive mechanism for driving the fork to rotate, and the fork comprises a feeding arm and a discharging arm, the discharging arm is located on the same side of the feeding arm as the feeding block, and the feeding arm is located between the limiting block and the feeding block.

[0008] Place the steel core with mother roll on the guide rail, and then roll the steel core along the guide rail to the feeding block and rest on the guide slope;

[0009] Then, the rotary drive mechanism drives the fork to rotate, so that the feeding arm rotates upward and rests on the steel core and pushes the steel core upward along the guide slope to the specified position.

[0010] When the unwinding of the film on the steel core is completed, the fork is driven to rotate by the rotary drive mechanism, the discharging arm is rotated upward, the feeding arm is rotated downward below the guide rail, and the discharging arm is abutted against the steel core to push the empty steel core along the guide rail to the limiting block. After the discharging arm is separated from the empty steel core, the empty steel core will roll along the guide rail to the limiting block until the empty steel core is abutted against the limiting block. Thus, the unwinding steel core bracket device of the slitting machine can not only push the steel core to the position of the specified chuck, but also automatically push out the empty steel core during the unwinding, greatly reducing the dependence on manpower, thereby improving the production efficiency and reducing the labor intensity. The unwinding steel core bracket device of the slitting machine is especially suitable for the unwinding steel core (the weight of the steel core with a mother roll exceeding 15 tons) applied to the super-wide slitting machine (more than 7.5 meters), which can effectively improve the production efficiency and reduce the labor intensity.

[0011] As preferred, when the steel core supported on the guide rail is close to or abutted against the guide slope, the feeding arm is driven to rotate upward by the rotary drive mechanism, so that the feeding arm is abutted against the steel core and pushes the steel core upward along the guide slope to the specified position.

[0012] When the steel core supported on the guide rail is close to or abutted against the guide slope, the discharging arm is driven to rotate upward by the rotary drive mechanism, so that the feeding arm is rotated to below the guide rail, and the discharging arm is abutted against the steel core to push the steel core along the guide rail to the limiting block.

[0013] As preferred, the feeding arm and the discharging arm form a fork opening upward, and the opening of the fork opening gradually increases from bottom to top. In this way, it is beneficial for the feeding arm to push the steel core upward along the guide slope to the specified position.

[0014] As preferred, the feeding arm and the discharging arm are in V-shaped distribution. In this way, it is beneficial for the feeding arm to push the steel core upward along the guide slope to the specified position, and it is beneficial for the discharging arm to push the steel core along the guide rail to the limiting block.

[0015] As preferred, the steel core bracket is provided with a fork limiting piece, and the fork limiting piece limits the angle of the feeding arm rotating upward driven by the rotary drive mechanism. In this way, during the process that the fork is driven to rotate by the rotary drive mechanism, the feeding arm is rotated upward to be abutted against the steel core and pushes the steel core upward along the guide slope, when the fork is abutted against the fork limiting piece, the steel core is pushed upward along the guide slope to the specified position, thereby accurately controlling the steel core to move upward along the guide slope to the specified position.

[0016] As preferred, the feeding arm and the discharging arm of the fork are in an integral structure. In this way, it is convenient for the actual production of the fork.

[0017] As preferred, the rotary drive mechanism is a pneumatic cylinder or an electric cylinder, the cylinder body end of the pneumatic cylinder or the electric cylinder is hingedly connected with the steel core bracket, and the piston rod end of the pneumatic cylinder or the electric cylinder is hingedly connected with the fork.

[0018] As preferred, the side of the limiting block towards the feeding block is a limiting inclined surface, and the upper part of the limiting inclined surface is inclined away from the feeding block. When the discharging arm pushes the steel core along the guide rail towards the limiting block, the empty steel core will roll along the guide rail towards the limiting block and abut against the limiting inclined surface. Since the upper part of the limiting inclined surface is inclined away from the feeding block, the impact force between the empty steel core and the limiting inclined surface can be reduced, and the rebound of the empty steel core can be effectively reduced or avoided.

[0019] As preferred, the inclination angle of the guide inclined surface is 30-60 degrees. In the embodiment, the inclination angle of the guide inclined surface is 30 degrees, 40 degrees, 50 degrees or 60 degrees. If the inclination angle of the guide inclined surface is too large, the steel core cannot be pushed upwards to the designated position along the guide inclined surface by the feeding arm. If the inclination angle of the guide inclined surface is too small, the moving stroke of the steel core when pushed upwards to the designated position along the guide inclined surface by the feeding arm will be increased, and it is not convenient for the feeding arm to push the steel core upwards to the designated position along the guide inclined surface. Therefore, in the embodiment, the inclination angle of the guide inclined surface is 30-60 degrees, which is beneficial for the feeding arm to push the steel core upwards to the designated position along the guide inclined surface, and avoids the moving stroke of the steel core when pushed upwards to the designated position along the guide inclined surface.

[0020] As preferred, the guide rail is installed on the steel core bracket by bolts, and the guide rail is horizontally distributed. In this way, the installation and replacement of the guide rail are facilitated, and the steel core can roll along the guide rail towards the feeding block or the limiting block.

[0021] As preferred, the feeding block is installed on the steel core bracket by bolts, and the limiting block is installed on the steel core bracket by bolts. In this way, the installation and replacement of the feeding block and the limiting block are facilitated.

[0022] The beneficial effects of the present application are that the steel core can be pushed to the designated position of the chuck, and the empty steel core can be automatically pushed out during the roll changing, which greatly reduces the dependence on manpower, improves the production efficiency and reduces the labor intensity.

[0035] Specific Implementation Example 1, such as Figures 1-4 As shown, a slitting machine unwinding steel core support 1 device includes a steel core support 1 and a shift fork mechanism 2.

[0036] The steel core bracket 1 is provided with a guide rail 3 to support the steel core. The steel core bracket 1 is provided with a limiting block 4 and a feeding stop block 5 distributed along the direction of the guide rail 3. The feeding stop block 5 is provided with a guide slope 5.1 on the side facing the limiting block 4. The upper part of the guide slope 5.1 is inclined away from the limiting block 4.

[0037] The shift fork mechanism 2 includes a shift fork 2.1 rotatably mounted on the steel core bracket 1 and a rotary drive mechanism 2.2 for driving the shift fork 2.1 to rotate. In this embodiment, the rotary drive mechanism 2.2 is a pneumatic cylinder or an electric cylinder. The shift fork 2.1 includes a loading arm 2.11 and a unloading arm 2.12. The unloading arm 2.12 and the loading stop 5 are located on the same side of the loading arm 2.11, and the unloading arm 2.12 is close to the loading stop 5. The loading arm 2.11 is located between the limiting block 4 and the loading stop 5.

[0038] The specific use of the unwinding steel core support device 1 for a slitting machine in this embodiment is as follows:

[0039] Place the steel core 6 with the mother coil on the guide rail 3, and then roll the steel core 6 along the guide rail 3 to the feeding stop 5 and abut against the guide slope 5.1;

[0040] Next, the rotary drive mechanism 2.2 drives the shift fork 2.1 to rotate, causing the loading arm 2.11 to rotate upward and press against the steel core, pushing the steel core 6 upward along the guide slope 5.1 to the designated position; thus realizing the automatic pushing of the steel core to the designated chuck position, after which the steel core can be clamped by the two chucks 7.

[0041] When the film on the steel core is unwound, the fork 2.1 is driven to rotate by the rotary drive mechanism 2.2, the discharge arm 2.12 is rotated upward, the feeding arm 2.11 is rotated downward below the guide rail 3, and the discharge arm 2.12 is abutted on the steel core to push the empty steel core along the guide rail 3 to the limiting block 4. After the discharge arm 2.12 is separated from the empty steel core, the empty steel core will roll along the guide rail 3 to the limiting block 4 until the empty steel core is abutted on the limiting block 4. Thus, the unwound steel core bracket 1 device of the slitting machine can not only push the steel core to the specified chuck position, but also automatically push out the empty steel core during the roll change, greatly reducing the dependence on manpower, thereby improving the production efficiency and reducing the labor intensity. The unwound steel core bracket 1 device of the slitting machine is especially suitable for the unwound steel core (the steel core with a length of more than 7.5 meters and a weight of more than 15 tons after the mother roll of the steel core band) applied to the super-wide slitting machine (more than 7.5 meters), which can effectively improve the production efficiency and reduce the labor intensity.

[0042] Specifically, as shown in Figures 1-4 The unwound steel core bracket 1 device of the slitting machine comprises a steel core bracket 1 and a fork mechanism 2.

[0043] The steel core bracket 1 is provided with a guide rail 3 for supporting the steel core. The steel core bracket 1 is provided with limiting blocks 4 and feeding blocks 5 distributed along the guide rail 3. The feeding block 5 is provided with a guide inclined surface 5.1 on the side facing the limiting block 4. The upper part of the guide inclined surface 5.1 is inclined away from the limiting block 4.

[0044] The fork mechanism 2 comprises a fork 2.1 rotatably arranged on the steel core bracket 1 and a rotary drive mechanism 2.2 for driving the fork 2.1 to rotate. The rotary shaft of the fork 2.1 is arranged below the guide rail 3. The fork 2.1 comprises a feeding arm 2.11 and a discharge arm 2.12. The discharge arm 2.12 and the feeding block 5 are located on the same side of the feeding arm 2.11, and the discharge arm 2.12 is close to the feeding block 5. The feeding arm 2.11 is located between the limiting block 4 and the feeding block 5.

[0045] During the rotation of the fork 2.1, when the feeding arm 2.11 rotates upward around the rotary shaft of the fork 2.1, the discharge arm 2.12 rotates downward around the rotary shaft of the fork 2.1; when the discharge arm 2.12 rotates upward around the rotary shaft of the fork 2.1, the feeding arm 2.11 rotates downward around the rotary shaft of the fork 2.1.

[0046] The fork 2.1 can rotate downward around the rotary shaft of the fork 2.1 until the guide rail 3 is below the feeding arm 2.11, so that the steel core supported on the guide rail 3 can roll along the guide rail 3 to the feeding block 5 or the limiting block 4 beyond the feeding arm 2.11.

[0047] When the steel core supported on the guide rail 3 approaches or abuts against the guide slope 5.1, the feeding arm 2.11 can be driven by the rotary driving mechanism 2.2 to rotate upward, so that the feeding arm 2.11 abuts against the steel core and pushes the steel core upward along the guide slope 5.1 to a designated position.

[0048] When the steel core supported on the guide rail 3 approaches or abuts against the guide slope 5.1, the feeding arm 2.11 can be driven by the rotary driving mechanism 2.2 to rotate upward, so that the feeding arm 2.11 abuts against the steel core and pushes the steel core upward along the guide slope 5.1 to a designated position.

[0049] The rotary driving mechanism 2.2 is a pneumatic cylinder or an electric cylinder. The cylinder end of the pneumatic cylinder or the electric cylinder is hingedly connected to the steel core bracket 1, and the piston rod end of the pneumatic cylinder or the electric cylinder is hingedly connected to the yoke 2.1. Specifically,

[0050] In one example, the cylinder end of the pneumatic cylinder or the electric cylinder constituting the rotary driving mechanism 2.2 is hingedly connected to the steel core bracket 1, and the piston rod end of the pneumatic cylinder or the electric cylinder is hingedly connected to the discharging arm 2.12.

[0051] In another example, the cylinder end of the pneumatic cylinder or the electric cylinder constituting the rotary driving mechanism 2.2 is hingedly connected to the steel core bracket 1, and the piston rod end of the pneumatic cylinder or the electric cylinder is hingedly connected to the feeding arm 2.11.

[0052] The specific use of the unwinding steel core bracket 1 device of the slitting machine of the embodiment is as follows,

[0053] As shown in Figure 3 , Figure 4 , the mother roll steel core 6 is placed on the guide rail 3, and then the steel core is rolled along the guide rail 3 to the feeding block 5 and abuts against the guide slope 5.1;

[0054] Then, the yoke 2.1 is driven to rotate by the rotary driving mechanism 2.2, so that the feeding arm 2.11 rotates upward and abuts against the steel core and pushes the steel core 6 upward along the guide slope 5.1 to a designated position (for example, the rotary driving mechanism 2.2 drives the yoke 2.1 to rotate clockwise, so that the feeding arm 2.11 rotates upward and abuts against the steel core and pushes the steel core 6 upward along the guide slope 5.1 to a designated position); Figure 3 Thus, the steel core is automatically pushed to the position of the designated chuck, and then the steel core can be clamped by the two chucks. When the two chucks 7 clamp the two ends of the steel core 6, the steel core is aligned by the cooperation of the tapered head and the tapered hole. Specifically, the two chucks are provided with tapered heads on the opposite end faces, and the tapered heads on the two chucks are coaxial. The two end faces of the steel core are provided with tapered holes matched with the tapered heads. When the two chucks clamp the two ends of the steel core, the tapered heads are inserted into the corresponding tapered holes, thereby automatically aligning the steel core to make the steel core coaxial with the two chucks. At the same time, the steel core is separated from the guide slope 5.1.

[0055] After the film on the steel core is unwound, the rotary drive mechanism 2.2 drives the fork 2.1 to rotate, causing the unloading arm 2.12 to rotate upwards and the loading arm 2.11 to rotate downwards to below the guide rail 3. The unloading arm 2.12 then presses against the steel core, pushing the empty steel core along the guide rail 3 towards the limiting block 4. Figure 3 For example, the rotary drive mechanism 2.2 drives the shift fork 2.1 to rotate counterclockwise, causing the unloading arm 2.12 to rotate upwards and the loading arm 2.11 to rotate downwards to below the guide rail 3. The unloading arm 2.12 then presses against the steel core, pushing the empty steel core along the guide rail 3 towards the limiting block 4. After the unloading arm 2.12 separates from the empty steel core, the empty steel core will roll along the guide rail 3 towards the limiting block 4 until it presses against the limiting block 4. Therefore, the uncoiling steel core support device 1 for a slitting machine in this embodiment can both push the steel core to the designated chuck position and automatically eject the empty steel core during roll changes, greatly reducing reliance on manual labor, thereby improving production efficiency and reducing labor intensity. The uncoiling steel core support device 1 for a slitting machine in this embodiment is particularly suitable for uncoiling steel cores (steel cores with a length of 7.5 meters or more and a weight exceeding 15 tons after the mother roll) used in ultra-wide slitting machines (7.5 meters or more), effectively improving production efficiency and reducing labor intensity.

[0056] Specifically, such as Figure 4 As shown, there are two steel core brackets 1. The two steel core brackets 1 are distributed along the axial direction of the steel core. Each steel core bracket 1 is equipped with a guide rail 3, a limiting block 4, and a feeding stop block 5. The guide rails 3 on the two steel core brackets 1 are at the same height and are parallel. A shift fork mechanism 2 corresponds one-to-one with each steel core bracket 1, and the shift forks 2.1 on the two steel core brackets 1 are at the same height. The two ends of the steel core are supported on the guide rails 3 of the two steel core brackets 1. In actual operation...

[0057] When the steel core rolls along the guide rail 3 to the feeding stop 5 and abuts against the guide slope 5.1, the shift fork mechanisms 2 on the two steel core brackets 1 work synchronously. The corresponding shift fork 2.1 is driven to rotate by the corresponding rotary drive mechanism 2.2, so that the feeding arms 2.11 of the shift fork mechanisms 2 on the two steel core brackets 1 rotate upward and abut against the two ends of the steel core. Then, the two ends of the steel core are pushed upward along the guide slope 5.1 to the designated position. Thus, the steel core is automatically pushed to the position of the designated clamp, and then the steel core can be clamped by the two clamps.

[0058] After the film on the steel core is unwound, the shift fork mechanisms 2 on the two steel core brackets 1 work synchronously. The corresponding rotary drive mechanism 2.2 drives the corresponding shift fork 2.1 to rotate, causing the unloading arms 2.12 on the two steel core brackets 1 to rotate upward and abut against both ends of the steel core, pushing the empty steel core along the guide rail 3 towards the limit block 4. The empty steel core rolls along the guide rail 3 towards the limit block 4 until the empty steel core abuts against the limit block 4.

[0059] Further, as shown in Figure 1 The inclination angle of the guide slope 5.1 is 30-60 degrees, and in the embodiment, the inclination angle of the guide slope 5.1 is 30 degrees, 40 degrees, 50 degrees or 60 degrees. If the inclination angle of the guide slope 5.1 is too large, it is not conducive to the feeding arm 2.11 to push the steel core along the guide slope 5.1 to the designated position. If the inclination angle of the guide slope 5.1 is too small, the moving stroke of the feeding arm 2.11 to push the steel core along the guide slope 5.1 to the designated position will increase, which is also not conducive to the feeding arm 2.11 to push the steel core along the guide slope 5.1 to the designated position. Therefore, in the embodiment, the inclination angle of the guide slope 5.1 is between 30-60 degrees, which is conducive to the feeding arm 2.11 to push the steel core along the guide slope 5.1 to the designated position, and avoids the moving stroke of the feeding arm 2.11 to push the steel core along the guide slope 5.1 to the designated position to be too large.

[0060] Further, as shown in Figure 1 , Figure 3 The feeding arm 2.11 and the discharging arm 2.12 form a fork opening upward, and the opening of the fork opening gradually increases from bottom to top. In this way, it is conducive to the feeding arm 2.11 to push the steel core along the guide slope 5.1 to the designated position.

[0061] The feeding arm 2.11 and the discharging arm 2.12 are in V-shaped distribution. The upper end of the feeding arm 2.11 is inclined to one side of the limiting block 4. The upper end of the discharging arm 2.12 is inclined away from the limiting block 4. In this way, it is conducive to the feeding arm 2.11 to push the steel core along the guide slope 5.1 to the designated position, and it is also conducive to the discharging arm 2.12 to push the steel core along the guide rail 3 to the limiting block 4.

[0062] The feeding arm 2.11 and the discharging arm 2.12 of the fork 2.1 are integrally formed. In this way, it is convenient for the actual production of the fork 2.1. Of course, it should be noted that the feeding arm 2.11 and the discharging arm 2.12 can also be separately manufactured, and then connected as a whole through welding or bolts.

[0063] Further, the steel core bracket 1 is provided with a fork limiting piece, which limits the angle of the feeding arm 2.11 rotating upward driven by the rotating driving mechanism 2.2. When the fork 2.1 abuts against the fork limiting piece, the feeding arm 2.11 cannot rotate upward any more. In this way, in the process of rotating the fork 2.1 driven by the rotating driving mechanism 2.2 to rotate the feeding arm 2.11 upward to abut against the steel core and push the steel core along the guide slope 5.1 upward, when the fork 2.1 abuts against the fork limiting piece, the steel core is pushed along the guide slope 5.1 to the designated position, so as to accurately control the steel core to move along the guide slope 5.1 to the designated position.

[0064] Further, as shown inFigure 1 As shown in the drawings, the side of the limiting block 4 facing the feeding block 5 is a limiting inclined surface 4.1, and the upper part of the limiting inclined surface 4.1 is inclined away from the feeding block 5. When the discharging arm 2.12 pushes the steel core along the guide rail 3 towards the limiting block 4, the empty steel core will roll along the guide rail 3 towards the limiting block 4 and abut against the limiting inclined surface 4.1. Since the upper part of the limiting inclined surface 4.1 is inclined away from the feeding block 5, the positive collision force between the empty steel core and the limiting inclined surface 4.1 can be reduced, effectively reducing or avoiding the rebound of the empty steel core.

[0065] Of course, it should be noted that the side of the limiting block 4 facing the feeding block 5 is provided as a limiting inclined surface 4.1, which is only one preferred scheme. The side of the limiting block 4 facing the feeding block 5 can also be provided as a vertical surface.

[0066] Further, the guide rail 3 is bolted to the steel core bracket 1, and the guide rail 3 is horizontally distributed. In this way, the installation and replacement of the guide rail 3 are facilitated, and the rolling of the steel core along the guide rail 3 towards the feeding block 5 or the limiting block 4 is facilitated. Of course, the guide rail 3 can also be welded to the steel core bracket 1.

[0067] Further, the feeding block 5 is bolted to the steel core bracket 1, and the limiting block 4 is bolted to the steel core bracket 1. In this way, the installation and replacement of the feeding block 5 and the limiting block 4 are facilitated. Of course, the feeding block 5 can also be welded to the steel core bracket 1, and the limiting block 4 can also be welded to the steel core bracket 1.

[0068] The above is only a preferred embodiment of the present application, and does not limit the present application in any way. Any simple modification, change, and equivalent transformation of the above embodiment according to the technical essence of the present application still falls within the protection scope of the technical solution of the present application.
