In order to effectively arrange the packing area, the original ladder type paper rack device occupies a large area, and the steel coil packing paper needs to be operated by multiple people, and the operation efficiency is low, and there is a safety risk. Therefore, there is an urgent need for a new scheme to solve the above technical problems. SUMMARY

[0003] The present application is aimed at the problems existing in the prior art, and provides an automatic paper rack device for steel coil packing paper, which mainly solves the technical problems of large occupation area and operation risk of the existing ladder type paper rack. The device can automatically and safely and reliably put the steel coil packing paper on the paper rack, improve the space utilization rate, reduce the influence on the site environment, improve the labor efficiency, reduce the labor intensity, and facilitate the processing of the next process. From the essence of the equipment safety, the operation safety risk is reduced, and the operation safety is improved.

[0004] In order to achieve the above purpose, the technical scheme of the present application is as follows: an automatic paper rack device for steel coil packing paper, the paper rack device comprises a driving motor, a shaft coupling, a roller, a pressing rod, a shaft seat, a paper rack device, a steel coil packing paper, a steel pipe and a steel pipe support, the driving motor drives the roller through the shaft coupling, the driving motor is above the paper rack device, the motor drives the roller, the steel wire rope acts on the steel pipe, the steel coil packing paper realizes the ascending and descending action, and the steel coil packing paper is placed on the steel pipe support after reaching a certain height. The steel pipe support can rotate freely; the driving motor is forward and reverse to make the steel coil packing paper ascend and descend in the vertical direction, instead of the operation of the crane or the forklift, and one person can operate. The power of the driving motor is selected according to the importance of the packing paper multiplied by a safety factor.

[0005] As an improvement of the present application, the roller is provided with two independent areas which do not interfere with each other, and the roller is provided with a pressing rod. The jumping of the steel wire rope is prevented, and the stable ascending and descending of the steel coil packing paper is ensured.

[0006] As an improvement of the present application, the steel pipe support is freely rotatable through a supporting cylindrical pin and an operating handle, and the operating handle is arranged on the side of the paper rack device, which is convenient and safe and reliable to operate.

[0007] As an improvement of the present invention, two supporting cylindrical pins are provided, arranged horizontally and symmetrically, and installed on the paper holder device. During operation, the supporting cylindrical pins near the operating handle are removed, and the operating handle is at a 90° angle to the supporting cylindrical pins on the side of the paper holder device, avoiding operation in dangerous areas and ensuring safety.

[0008] As an improvement of the present invention, the cylindrical pin and the operating handle are on the same horizontal plane and are used together to fix the steel pipe support. When the operating handle and the cylindrical pin supporting the side near the operating handle are removed, the steel pipe support can rotate freely. A stop is set at the position of 90° clockwise rotation to prevent over-rotation.

[0009] As an improvement of the present invention, the steel pipe support provides stable support for the steel pipe and the steel coil packaging paper through three-point positioning. Two of the three points are two bearings, and the third point is a front support tangent to the outer circle of the steel pipe. The bearings are selected to match the diameter of the steel coil. The three points form an equilateral triangle, which ensures stable positioning and requires less effort during operation; the steel coil packaging paper will rotate without much force. After the steel coil packaging paper is in place, the operating handle is fixed.

[0010] As an improvement of the present invention, the bearing is mounted on the shaft, and the length of the steel pipe is designed to be the length of the shaft (and the shaft sleeve), while also facilitating maintenance and replacement. Finally, the shaft is fixed by a clamping plate.

[0011] As an improvement of the present invention, the paper rack device is used in pairs, with the same width and position as the steel pipe, 200mm wider than the packing roll of paper, and 100mm on each side, which facilitates forklift operation. At the same time, multiple steel pipe supports can be installed on the same vertical space, thereby improving the utilization rate of site space.

[0012] Furthermore, the bottom of the paper holder is fixed with M27 expansion bolts, which facilitates on-site installation and positioning, and is stable and reliable according to strength calculations, and will not tip over.

[0013] A method for an automatic paper feeding device for steel coil packaging paper rolls, the method comprising the following steps:

[0014] Step 1) First, use a steel pipe to wrap the paper roll and place it near the paper rack device using a hydraulic handcart.

[0015] Step 2) The workers use wire rope to tie both ends of the steel pipe securely, and place the steel coil packaging paper in the middle of the steel pipe;

[0016] Step 3) The operator removes the support cylindrical pin and operates the handle to rotate the steel pipe support 90° clockwise until it stops at the positioning block;

[0017] Step 4) Turn on the motor power, operate the motor to rotate and confirm the direction. The drive motor rotates, causing the steel coil and the packaging paper roll to rise;

[0018] Step 5) The steel coil packaging paper roll automatically rises to a fixed height, senses the limit switch, cuts off the motor power through the closed-loop control program, resets the operating handle, and installs the cylindrical pin to fix the operating handle.

[0019] Step 6) Reverse the motor to automatically lower the steel coil packaging paper, placing the steel pipe on the steel pipe support, thus completing the automatic paper feeding operation of the steel coil packaging paper.

[0020] Step 7) Once in position, untie the wire rope, pull the power cord, and the operation is complete.

[0021] Compared to existing technologies, this invention offers the following advantages: This technical solution can automatically, safely, and reliably load the steel coil packaging paper onto the paper rack, improving space utilization and reducing the impact on the environment; it also increases labor efficiency, reduces labor intensity, and facilitates subsequent processing steps; finally, from the perspective of inherent equipment safety, it reduces operational safety risks and improves operational safety. The method involves using a drive motor to automatically load the steel coil packaging paper onto the paper rack, eliminating the need for overhead cranes or forklifts and allowing for operation by a single person, thus reducing labor intensity. When loading the steel coil packaging paper is required, the operator simply follows the steps described above. This invention fills a gap in existing technology, yields significant social benefits, and is worthy of widespread adoption in the industry. Attached Figure Description

[0027] To enhance understanding of the present invention, the embodiments will be described in detail below with reference to the accompanying drawings.

[0028] Example 1: See Figures 1-6An automatic paper-feeding device for steel coil packaging rolls is disclosed. The paper-feeding device includes a drive motor 1, a coupling 2, a roller 3, a pressure rod 4, a bearing 5, a paper-feeding device 6, steel coil packaging rolls 7, a steel pipe 8, and a steel pipe support 9. The drive motor drives the roller 1 through the coupling. The drive motor 1 is located above the paper-feeding device 6. The rotation of the motor drives the roller 3, which in turn pulls the steel pipe 8 through a traction steel wire rope, causing the steel coil packaging rolls 7 to rise and fall. After reaching a certain height, the steel coil packaging rolls 7 are placed on the steel pipe support 9, which can rotate freely. The forward and reverse rotation of the drive motor 1 enables the steel coil packaging rolls 7 to rise and fall vertically, replacing the operation of overhead cranes or forklifts, allowing for operation by a single person. The power of the drive motor 1 is selected based on the importance of the packaging rolls 7 multiplied by a safety factor. The roller 3 has two independent areas that do not interfere with each other, and the roller is equipped with a pressure rod 4. To prevent the wire rope from jumping and ensure the steady rise and fall of the steel coil packaging paper, the steel pipe support 9 rotates freely via supporting cylindrical pins 10 and operating handles 11. The operating handles 11 are located on the side of the paper holder device 6, providing convenient and safe operation. Two supporting cylindrical pins 10 are provided, arranged horizontally and symmetrically, and installed on the paper holder device 6. During operation, the supporting cylindrical pin 10 closest to the operating handle 11 is removed. The operating handle 11 forms a 90° angle with the supporting cylindrical pin 10, located on the side of the paper holder device 6, avoiding operation in a dangerous area and ensuring safety. The cylindrical pins 10 and the operating handle 11 are on the same horizontal plane. The steel pipe support 9 is fixed together. When the operating handle 11 and the supporting cylindrical pin 10 near the operating handle 11 are removed, the steel pipe support 9 can rotate freely. A stop is set at the 90° clockwise rotation position to prevent over-rotation. The steel pipe support 9 is stably supported by three points of positioning, which are two bearings 16 and the third point is the front support 12 of the shaft that is tangent to the outer circle of the steel pipe 8. The bearings are selected to match the diameter of the steel coil. The three points form an equilateral triangle. This positioning is stable and saves effort during operation. The steel coil packaging paper 7 will rotate without much effort. After the steel coil packaging paper roll 7 is placed in position, the operating handle 11 is fixed. The bearing 16 is installed on the shaft 17. The length of the steel pipe 8 is designed to match the length of the shaft 17 and the bushing 15, while also facilitating maintenance and replacement. Finally, the shaft 17 is fixed by the clamping plate 13. The paper rack device 6 is used in pairs. Its width and position are the same as the steel pipe, but it is 200mm wider than the packaging paper roll 7, with 100mm on each side, which facilitates forklift operation. At the same time, multiple steel pipe supports 9 can be installed in the same vertical space, thereby improving the utilization rate of the site space. The bottom of the paper rack device 6 is fixed with M27 expansion bolts, which facilitates on-site installation and positioning. It is also stable and reliable after strength calculation and will not tip over.

[0030] Step 1) First, use a steel pipe to wrap the paper roll and place it near the paper rack device using a hydraulic handcart.

[0031] Step 2) The workers use wire rope to tie both ends of the steel pipe securely, and place the steel coil packaging paper in the middle of the steel pipe;

[0032] Step 3) The operator removes the support cylindrical pin and operates the handle to rotate the steel pipe support 90° clockwise until it stops at the positioning block;

[0033] Step 4) Turn on the motor power, operate the motor to rotate and confirm the direction. The drive motor rotates, causing the steel coil and the packaging paper roll to rise;

[0034] Step 5) The steel coil packaging paper roll automatically rises to a fixed height, senses the limit switch, cuts off the motor power through the closed-loop control program, resets the operating handle, and installs the cylindrical pin to fix the operating handle.

[0035] Step 6) Reverse the motor to automatically lower the steel coil packaging paper, placing the steel pipe on the steel pipe support, thus completing the automatic paper feeding operation of the steel coil packaging paper.

[0036] Step 7) Once in position, untie the wire rope, pull the power cord, and the operation is complete.
