DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a cold-rolled steel coil feeding protection structure, comprising a support rod 1, the top of the support rod 1 is fixedly connected with a hydraulic telescopic rod 2, the other end of the hydraulic telescopic rod 2 is fixedly connected with a fixing frame 3, and the hydraulic telescopic rod 2 is telescoped in a horizontal plane. By setting the hydraulic telescopic rod 2, the position of the fixing frame 3 in the horizontal plane can be changed.

[0024] The inner cavity at the other end of the fixed frame 3 is movably connected with the rotating frame 4, and the middle parts of the two ends of the rotating frame 4 are fixedly connected with the rotating shaft 16, and the other end of the rotating shaft 16 is movably connected with the fixed frame 3, and the rotating frame 4 is movably connected with the fixed frame 3 through the rotating shaft 16. One end of the fixed frame 3 is fixedly connected with a rotating motor 6, and the output shaft end of the rotating motor 6 is fixedly connected to the end of the rotating shaft 16 through a reducer. Through the setting of the rotating motor 6, the rotation of the rotating motor 6 can drive the rotating shaft 16 fixedly connected thereto to rotate, and the rotating shaft 16 drives the rotating frame 4 fixedly connected thereto to rotate.

[0025] A hydraulic telescopic rod 2 5 is fixedly connected to the middle of the rotating frame 4, a connecting block 10 is fixedly connected to the bottom of the hydraulic telescopic rod 2 5, and a middle pressure roller 12 is fixedly connected to one end of the connecting block 10 away from the support rod 1. Through the setting of the hydraulic telescopic rod 2 5, the extension and retraction of the hydraulic telescopic rod 2 5 can change the height of the middle pressure roller 12 in the vertical direction.

[0026] The other end of the rotating frame 4 is movably connected with a bidirectional ball screw 17, which is located above the middle pressure roller 12. One end of the rotating frame 4 is fixedly connected with a rotating motor 2 7, and the output shaft end of the rotating motor 2 7 is fixedly connected to the middle of the end of the bidirectional ball screw 17 through a reducer. Through the setting of the rotating motor 2 7, the rotation of the rotating motor 2 7 can drive the bidirectional ball screw 17 fixedly connected thereto to rotate.

[0027] Both ends of the bidirectional ball screw 17 are threadedly connected with ball nuts 11. When the bidirectional ball screw 17 rotates, the two ball nuts 11 can move in the direction of the bidirectional ball screw 17, and the distance between the two ball nuts 11 can change.

[0028] The bottom of the ball nut 11 is fixedly connected to a hydraulic telescopic rod 3 8, and the bottom of the hydraulic telescopic rod 3 8 is fixed with another connecting block 10. The end of the other connecting block 10 away from the support rod 1 is fixedly connected to a side pressure roller 9. The two side pressure rollers 9 are at the same height, and the middle pressure roller 12 is located above the middle of the two side pressure rollers 9.

[0029] By setting the hydraulic telescopic rod 3 8, the extension and retraction of the hydraulic telescopic rod 3 8 can change the position of the side pressure roller 9 connected thereto in the vertical direction, so that the side pressure roller 9 is in contact with the steel coil, and during the rotation of the rotating frame 4, the space occupied by the rotating frame 4 can be reduced, so as to facilitate the rotation of the rotating frame 4. By setting the bidirectional ball screw 17, the rotation of the bidirectional ball screw 17 can change the distance between the two side pressure rollers 9.

[0030] From the above description, it can be seen that when the protective structure is in use, the distance between the side pressure roller 9 and the middle pressure roller 12, the position of the side pressure roller 9 and the position of the middle pressure roller 12 can all be changed, so that the protective structure can adapt to cold-rolled steel coils of various sizes, thereby improving the adaptability of the structure, and the side pressure roller 9 and the middle pressure roller 12 can be separated from the steel coil to facilitate the taking and placing of the steel coil.

[0031] The outer surface of the middle pressure roller 12 and the outer surface of the side pressure roller 9 are both wrapped with a buffer pad. Through the setting of the buffer pad, the buffer pad can increase the friction between the steel coil and the middle pressure roller 12 or the side pressure roller 9, which is convenient for the structure to limit the steel bar, and the rebound force of the buffer pad can reduce the impact force of the steel coil on the middle pressure roller 12 and the side pressure roller 9 when the steel coil is untied.

[0032] The above-mentioned middle pressure roller 12 and side pressure roller 9 both include a roller body 13 and a roller body 15. The roller body 13 and the roller body 15 are connected by a screw 14. One end of the screw 14 is fixedly connected to the roller body 13, and the other end of the screw 14 is threadedly connected to the roller body 15. Through the setting of the screw 14, the distance between the roller body 13 and the roller body 15 can be changed, so that the middle pressure roller 12 and the side pressure roller 9 can adapt to cold-rolled steel coils of various widths, thereby improving the adaptability of the protective structure.

[0033] A scale line is provided on one side of the screw rod 14 , and the scale line is provided to facilitate the user to control the length of both the middle pressure roller 12 and the side pressure roller 9 .

[0034] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0035] In summary: when the cold-rolled steel coil feeding protection structure is used, the support rod 1 is fixed on the steel coil placement tray of the cold-rolled steel coil feeding device. After the steel coil is placed on the steel coil tray, the rotating motor 16 drives the rotating shaft 16 fixedly connected thereto to rotate, and the rotating shaft 16 drives the rotating frame 4 fixedly connected thereto to rotate, and the rotating frame 4 drives the middle pressure roller 12 and the side pressure roller 9 to rotate. At this time, the middle pressure roller 12 and the side pressure roller 9 are both changed from a vertical placement state to a horizontal placement state. The hydraulic telescopic rod 12 is extended, and the hydraulic telescopic rod 12 drives the middle pressure roller 12 and the side pressure roller 9 to move until the middle pressure roller 12 and the side pressure roller 9 move to the top of the steel coil, and the hydraulic telescopic rod 2 5 drives the middle pressure roller 12 to move down until the bottom of the middle pressure roller 12 contacts the top of the steel coil, and the hydraulic telescopic rod 3 8 drives the side pressure roller 9 to move down until the side pressure roller 9 can contact the steel coil, and the rotating motor 2 7 drives the bidirectional ball screw 17 to rotate, and the rotation of the bidirectional ball screw 17 causes the two side pressure rollers 9 to gradually approach each other. The steel coil is limited by the middle pressure roller 12 and the side pressure roller 9 to prevent the steel coil from shifting and spreading during the loading process. When the steel coil needs to be taken and placed, the restriction of the middle pressure roller 12 and the side pressure roller 9 on the steel coil is released, and the rotating frame 4 rotates until the middle pressure roller 12 and the side pressure roller 9 are changed from a horizontally placed state to a vertically placed state, and the hydraulic telescopic rod 2 is contracted, and the hydraulic telescopic rod 2 drives the middle pressure roller 12 and the side pressure roller 9 away from the steel coil, so as to facilitate the taking and placing of the steel coil.
