[0030] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The embodiment of the present application discloses a steel coil feeding device.

[0033] Reference Figure 1 The steel coil feeding device includes a frame 1, a driving screw 2, a first limit plate 3, a second limit plate 4 and a mounting column 5. The driving screw 2 is arranged along the width direction of the frame 1 and is rotatably connected to the frame 1. The driving screw 2 is provided with a first threaded portion 21 and a second threaded portion 22 at intervals along its own length direction, and the first threaded portion 21 is opposite to the second threaded portion 22.

[0034] The first limit plate 3 and the second limit plate 4 are symmetrically arranged and slidably connected to the frame 1. The sliding direction is the length direction of the driving screw 2. The first limit plate 3 is threadedly connected to the first threaded portion 21, and the second limit plate 4 is threadedly connected to the second threaded portion 22. When the driving screw 2 rotates, the first limit plate 3 and the second limit plate 4 slide in opposite directions to make the first limit plate 3 and the second limit plate 4 approach or move away from each other.

[0035] Reference Figure 1 and Figure 2 The mounting column 5 is fixedly connected to the first limiting plate 3, the mounting column 5 is arranged parallel to the driving screw 2, and one end of the mounting column 5 is slidably connected to the frame 1 along its own length direction, and the other end protrudes from the first limiting plate 3. At the same time, a clearance hole 41 is opened on the second limiting plate 4 for the mounting column 5 to pass through.

[0036] In actual application, the staff rotates the driving screw 2 to drive the first limit plate 3 and the second limit plate 4 to approach each other, so that the two sides of the steel coil installed on the mounting column 5 are limited between the first limit plate 3 and the second limit plate 4, thereby limiting the steel coil from shaking significantly on the mounting column 5, thereby facilitating the loading of the steel coil.

[0037] Among them, the staff drives the first limit plate 3 and the second limit plate 4 to move away from each other by rotating the driving screw 2. Since the mounting column 5 installed on the first limit plate 3 is slidably connected to the frame 1, the mounting column 5 slides with the first limit plate 3, and the mounting column 5 disengages from the clearance hole 41, so that there is a certain distance between the mounting column 5 and the second limit plate 4. At this time, the steel coil can be directly installed on one end of the mounting column 5, that is, sufficient installation space is provided for the steel coil, and the steel coil can be installed without removing the mounting column 5 from the frame 1, thereby facilitating the installation of the steel coil.

[0038] In some embodiments, the mounting column 5 is detachably connected to the first limiting plate 3, so that the mounting column 5 can be replaced. By replacing different mounting columns 5 to adjust the distance between the mounting column 5 and the second limiting plate 4, steel coils of a larger size range can be installed between the first limiting plate 3 and the second limiting plate 4, thereby improving the applicability of the steel coil loading device.

[0039] Reference Figure 3 and Figure 4In some embodiments, the steel coil feeding device further includes a fixing assembly 6. Specifically, the fixing assembly 6 includes a fixing block 61, a fixing rod 62 and a spring 63. The fixing block 61 is fixedly connected to the side of the first limiting plate 3 away from the second limiting plate 4. The fixing block 61 is provided with a through hole 611 for the installation column 5 to pass through. The fixing rod 62 is vertically arranged and slidably connected to the upper end of the fixing block 61 along its own length direction. Correspondingly, the peripheral side of the installation column 5 is provided with a fixing hole 51 matching the fixing rod 62. The upper end of the spring 63 is fixedly connected to the fixing rod 62, and the lower end is fixedly connected to the fixing block 61, so as to drive the fixing rod 62 to be inserted into the fixing hole 51. By pulling the fixing rod 62 upwards, the fixing rod 62 is disengaged from the fixing hole 51, and then the mounting column 5 is slid out of the frame 1, the mounting column 5 can be disassembled. At the same time, by sliding the mounting column 5, the mounting column 5 is passed through the fixing block 61, and the fixing rod 62 is inserted into the fixing hole 51 under the drive of the spring 63, the mounting column 5 can be installed, so as to realize the detachable connection between the mounting column 5 and the first limiting plate 3, which has a simple structure and is easy to operate.

[0040] The fixing assembly 6 also includes a connecting rod 64, which is slidably connected to the side of the fixing block 61 away from the first limit plate 3, and the sliding direction is the length direction of the mounting column 5. The end of the connecting rod 64 close to the fixing rod 62 has a contact surface 641, and the contact surface 641 is inclined. A guide groove 621 is provided on the side of the fixing rod 62 close to the connecting rod 64. The shape of the guide groove 621 matches the contact surface 641, so that the connecting rod 64 moves toward the end close to the fixing rod 62, and the contact surface 641 can contact the groove wall of the guide groove 621 to drive the fixing rod 62 away from the fixing hole 51. When the mounting column 5 needs to be disassembled, the driving screw 2 is rotated to make the first limit plate 3 and the second limit plate 4 move away from each other, so that the connecting rod 64 located on the side of the first limit plate 3 away from the second limit plate 4 abuts against the frame 1, and under the action of the abutting surface 641 and the guide groove 621, the fixing rod 62 moves upward to disengage the fixing rod 62 from the fixing hole 51, and there is no need to pull the fixing rod 62 upward, thereby facilitating the disassembly of the mounting column 5.

[0041] In some embodiments, there are multiple fixing holes 51, and the multiple fixing holes 51 are arranged at intervals along the length direction of the mounting column 5. The distance between the mounting column 5 and the second limiting plate 4 can be adjusted by inserting the fixing rod 62 into different fixing holes 51. The distance between the mounting column 5 and the second limiting plate 4 can be adjusted without replacing the mounting column 5, thereby facilitating adaptation to steel coils of different sizes.

[0042] In some embodiments, the mounting column 5 has a limiting groove 52 along its length direction, and the fixing block 61 is protruded from the through groove to form a limiting block 612. The limiting block 612 slides and is limited in the limiting groove 52, which can realize the positioning installation of the mounting column 5, so that the fixing rod 62 can be accurately inserted into the fixing hole 51, thereby facilitating the positioning installation of the mounting column 5.

[0043] Reference Figure 1 In some embodiments, the steel coil feeding device also includes a driving assembly 7, which includes a handwheel 71. The handwheel 71 is fixedly connected to one end of the driving screw 2 to facilitate the staff to apply force, thereby facilitating the rotation of the driving screw 2 and further facilitating the installation of the steel coil.

[0044] Reference Figure 1 and Figure 5 In some embodiments, the driving assembly 7 further includes a gear 72 and a rack 73, wherein the gear 72 is fixedly connected to one end of the driving screw 2 located at the hand wheel 71, and the rack 73 is slidably connected to one side of the frame 1, and the rack 73 is meshed with the gear 72 to limit the rotation of the driving screw 2, thereby improving the stability of the rotation of the driving screw 2. Since the diameter of the gear 72 is small, the rotation of the driving screw 2 can be quickly realized by sliding the rack 73, so as to facilitate the rapid installation of the steel coil.

[0045] In some embodiments, the driving assembly 7 further includes a push rod 74, which is fixedly connected to a side of the rack 73 away from the frame 1, so that the staff can apply force to facilitate pushing the rack 73 to slide.

[0046] In some embodiments, the driving assembly 7 also includes a slide rail 75 and a slider 76, the slide rail 75 is fixedly connected to one side of the frame 1, the slider 76 is fixedly connected to the rack 73, and the slider 76 is slidably connected to the slide rail 75 to facilitate the sliding of the rack 73 and improve the sliding stability of the rack 73.

[0047] The implementation principle of this embodiment is: in actual application, the staff drives the first limit plate 3 and the second limit plate 4 to approach each other by rotating the driving screw 2, so that the two sides of the steel coil installed on the mounting column 5 are limited between the first limit plate 3 and the second limit plate 4, thereby limiting the steel coil from shaking significantly on the mounting column 5, thereby facilitating the loading of the steel coil.

[0048] Among them, the staff drives the first limit plate 3 and the second limit plate 4 to move away from each other by rotating the driving screw 2. Since the mounting column 5 installed on the first limit plate 3 is slidably connected to the frame 1, the mounting column 5 slides with the first limit plate 3, and the mounting column 5 disengages from the clearance hole 41, so that there is a certain distance between the mounting column 5 and the second limit plate 4. At this time, the steel coil can be directly installed on one end of the mounting column 5, that is, sufficient installation space is provided for the steel coil, and the steel coil can be installed without removing the mounting column 5 from the frame 1, thereby facilitating the installation of the steel coil.
