[0002] A decoiler is a special equipment for leveling metal sheets. It is mainly used to open and unwind metal coils, and at the same time draw out the material head so that it can smoothly enter the subsequent processing production line, such as automated processing production lines like stamping, leveling, laser cutting, shearing lines, etc. The body of the decoiler is generally a welded box-shaped structure and works by driving the reel shaft through a variable-frequency speed-regulating motor. During the processing of metal sheets, the decoiler can be configured to form a decoiling, leveling, shearing production line or other sheet product production lines according to relevant configurations.

[0003] However, there are still significant deficiencies in the prior art, such as:

[0004] The auxiliary loading device of the decoiler in the prior art lacks a flexible detachment mechanism, resulting in a cumbersome switching process between the loading and decoiling processes, requiring more manual intervention and adjustment, and increasing the complexity and difficulty of operation.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1-6 , the present utility model provides a technical solution:

[0027] Embodiment 1:

[0028] An auxiliary loading device for an uncoiler, which mainly consists of a base 1, an uncoiler main body 2, a reducer 3, a driving motor 4, and a shaft connection mechanism 15, etc.

[0029] The base 1 is the stable foundation of the entire device, on which the uncoiler main body 2 is fixedly arranged. The uncoiler main body 2, as the core component, is responsible for the uncoiling work of the coil material. On one side of the uncoiler main body 2, a reducer 3 is fixedly arranged, which is a key link for power transmission and is driven by the driving motor 4. The power generated by the driving motor 4 is decelerated and torque-increased by the reducer 3 and then transmitted to the first rotating shaft 5.

[0030] The first rotating shaft 5 is connected to the low-speed end of the reducer 3 by a fastening method to ensure the stability of power transmission. The first rotating shaft 5 not only penetrates the uncoiler main body 2 but also has a driving gear 6 fixedly arranged at its other end. This driving gear 6 is an important component for subsequent meshing transmission with the driven gear 14.

[0031] The auxiliary loading mechanism 7 utilizes the stability principle of a triangle and jointly forms a stable triangular structure through the base 1, the support rod 9, and the support hydraulic cylinder 10. On the base 1, a number of rotating seats 8 are fixedly arranged, and these rotating seats 8 provide an installation foundation for the subsequent support rod 9 and support hydraulic cylinder 10. At the other end of the support rod 9, a second rotating sleeve 12 is fixedly arranged, while at the movable end of the support hydraulic cylinder 10, a first rotating sleeve 11 is fixedly arranged. It should be noted that the movable end of the support hydraulic cylinder 10 is not directly fixed on the support rod 9, but is rotatably arranged on the second rotating sleeve 12 through the first rotating sleeve 11. This design enables the support hydraulic cylinder 10 to maintain a certain degree of flexibility when expanding and contracting.

[0032] In the second rotating sleeve 12, a second rotating shaft 13 is rotatably arranged. At one end of the second rotating shaft 13, a driven gear 14 is fixedly arranged, and this driven gear 14 is meshed and driven with the driving gear 6 in a separable manner. When feeding is required, by adjusting the expansion and contraction state of the support hydraulic cylinder 10, the meshing or disengagement of the driven gear 14 and the driving gear 6 can be controlled, thereby realizing the flexible switching between the feeding and uncoiling processes of the coiled material.

[0033] The shaft connection mechanism 15 mainly consists of a first flange 17 and a second flange 18. The first flange 17 is fixedly arranged at one end of the driven gear 14, while the second flange 18 is fixedly arranged at the end of the uncoiling shaft 16. The two are fixedly connected by bolts. This connection method is not only simple in structure and convenient to operate, but also firm and reliable in connection, and can ensure the stability of the uncoiling shaft 16 during rotation.

[0034] In actual operation, first of all, the operators need to carry out preliminary preparation work. They will come to the uncoiler, find and confirm each component in the auxiliary feeding device, especially the first flange 17 and the second flange 18 in the shaft connection mechanism 15. These two flanges are respectively firmly fixed at one end of the driven gear 14 and the end of the uncoiling shaft 16, and are key components connecting the uncoiling shaft 16 and the driven gear 14.

[0035] Next, the operators will use tools (such as wrenches or special fixtures) to loosen the bolts connecting the first flange 17 and the second flange 18 one by one to ensure that the connection between the two is completely disconnected. Subsequently, they will remove the uncoiling shaft 16 from the auxiliary loading mechanism 7 and prepare to insert it into the coiled material to be uncoiled.

[0036] After the uncoiling shaft 16 is successfully inserted into the coiled material, the operators will push or use other auxiliary equipment to roll the coiled material to a position close to the first flange 17. At this time, the coiled material is preliminarily positioned and ready to be docked with the uncoiler.

[0037] Subsequently, the operator starts the support hydraulic cylinder 10. As the hydraulic cylinder contracts, its movable end drives the first rotating sleeve 11 to move downward, and then the driven gear 14 that was originally engaged with the driving gear 6 gradually disengages. At the same time, due to the action of the support hydraulic cylinder 10, the height of the first flange 17 also decreases, which provides the operator with a larger operating space and enables them to more conveniently dock the first flange 17 with the second flange 18.

[0038] When the height positions of the first flange 17 and the second flange 18 are basically the same, the operator passes bolts through the reserved holes of both and uses tools to tighten the bolts. In this way, a firm connection is achieved between the first flange 17 and the second flange 18 through the bolts, and then the second rotating shaft 13, the driven gear 14, and the unwinding shaft 16 are tightly connected together.

[0039] After the docking is completed, the operator starts the support hydraulic cylinder 10 again, but this time makes it extend. As the hydraulic cylinder extends, the movable end of the support hydraulic cylinder 10 pushes the unwinding shaft 16 and the coil material connected thereto to gradually rise. When the driving gear 6 and the driven gear 14 reach the meshing position again, the operator promptly closes the support hydraulic cylinder 10 to ensure the stability and safety of the entire loading process.

[0040] Finally, the operator starts the driving motor 4. Driven by the driving motor 4, the speed reducer 3 drives the driving gear 6 to rotate through the first rotating shaft 5, and then through meshing transmission, the driven gear 14 and the unwinding shaft 16 also start to rotate. As the unwinding shaft 16 rotates, the coil material is gradually unwound and fed into the subsequent processing production line of the uncoiler to complete the entire uncoiling process.

[0041] Embodiment 2:

[0042] On the basis of Embodiment 1, this embodiment further optimizes and improves the auxiliary loading device of the uncoiler to enhance its overall performance and user experience.

[0043] First, aiming at the problem of possible shaking or instability of the coil material during the uncoiling process, a support plate 19 is added in the upper region of the uncoiler main body 2, that is, directly above the first rotating shaft 5. This support plate 19 is installed on the uncoiler main body 2 by a firm fixing method to provide a stable support platform. On the support plate 19, a pressure rod 20 is further fixedly arranged. The pressure rod 20 is designed to be perpendicular to the movement direction of the coil material to achieve a stable effect on the coil material.

[0044] In order to more effectively press the coil material and reduce its sliding or deviation, a pressure plate 21 is rotatably arranged on the pressure rod 20. The pressure plate 21 can be flexibly adjusted according to the actual width and position of the coil material. By rotating the pressure plate 21, it can be closely attached above the coil material, thereby providing a stable pressing force. In addition, in order to further enhance the pressing effect, a pressure wheel 22 is rotatably arranged on the pressure plate 21. The pressure wheel 22 can roll when the coil material moves, reducing the friction with the coil material, while maintaining a stable pressing force to prevent the coil material from deviating or being damaged during the uncoiling process.

[0045] In addition to optimizing the pressing of the coil material, the leveling treatment of the coil material has also been improved. At a position on one side of the uncoiler main body 2 where the uncoiling shaft 16 is located, a leveling box 23 is fixedly arranged. The design of the leveling box 23 enables it to accommodate and fix the leveling plate 24. On the leveling plate 24, a number of leveling shafts 25 are rotatably arranged. These leveling shafts 25 can be flexibly adjusted according to the material, thickness and width of the coil material. By rotating or adjusting the position of the leveling shafts 25, precise leveling treatment of the coil material can be achieved, ensuring that the uncoiled coil material is flat and without wrinkles.

[0046] In addition, in order to improve the safety performance of the uncoiler, a brake disc 26 is fixedly arranged on the first rotating shaft 5. The brake disc 26 cooperates with the brake 27 fixedly arranged in the uncoiler main body 2, and can quickly brake the rotation of the first rotating shaft 5 when needed, thereby preventing the coil material from continuing to move or being damaged in case of an accident. The design of this braking mechanism greatly improves the safety and reliability of the uncoiler.

[0047] Finally, in order to facilitate the pressing of the coil material, sleeves 28 are detachably arranged at both ends of the uncoiling shaft 16. One end of the sleeve 28 is fixedly provided with a pressure plate 29 for providing an additional pressing force when the coil material is uncoiled. At the same time, a positioning screw 30 is rotatably arranged on the sleeve 28. By rotating the positioning screw 30, the fixing and loosening operations of the sleeve 28 can be realized, so as to conveniently install the uncoiling shaft 16 onto the sleeve 28 or disassemble it from the sleeve 28. This detachable design not only improves the installation and disassembly efficiency of the uncoiling shaft 16, but also helps to reduce the maintenance cost and time.

[0048] Working principle: During the use of the present utility model, before feeding, the operator removes the uncoiling shaft 16 from the auxiliary feeding mechanism 7 by loosening the bolts and inserts the uncoiling shaft 16 into the coil material to be uncoiled.

[0049] Subsequently, the operator adjusts the telescopic state of the support hydraulic cylinder 10 to disengage the driven gear 14 from the driving gear 6, providing space for the docking of the uncoiling shaft 16 and the coil material.

[0050] After the docking is completed, the operator adjusts the supporting hydraulic cylinder 10 again to re-mesh the driven gear 14 with the driving gear 6, and lifts the coiled material to an appropriate position.

[0051] Finally, start the driving motor 4, and through meshing transmission, rotate the unwinding shaft 16, so as to unwind the coiled material and feed it into the subsequent processing production line.

[0052] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
