Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical technology, and in particular to a feeding roller transmission mechanism. Background Technology
[0002] Steel plates are hot-rolled steel plates made from ordinary carbon structural steel and rimmed steel. Existing steel plates can be formed by shearing steel coils, etc. The steel coils are conveyed by a pair of conventional conveyor rollers. However, in order to convey the steel coils, a motor is required. The motor is connected to one of the conveyor rollers, and the motor drives the conveyor roller to rotate, thereby conveying the steel coil. However, some materials need to be clamped by both conveyor rollers and rotated during the cutting process. At this time, the motor does not start, but the two conveyor rollers rotate. This rotation of the conveyor roller connected to the motor will damage the conveyor roller or the motor, affecting subsequent use. Announcement No. CN203221152U discloses a strip steel coil feeding device, comprising at least a frame (7); a first adjusting box (3) and a second adjusting box (9) connected to the upper ends of the frame (7); a motor (4) connected to the lower end of the frame (7); a reduction gearbox (1) connected to the upper end of the frame (7) and driven by the motor (4); a feeding shaft (6) driven by the reduction gearbox (1); and a pressure shaft (5). The feeding shaft (6) is rotatably connected to the lower part of the first adjusting box (3) and the second adjusting box (9), and the pressure shaft (5) is rotatably connected to the upper part of the first adjusting box (3) and the second adjusting box (9). The gap between the pressure shaft (5) and the feeding shaft (6) is adjustable. The motor of this mechanism is directly connected to the roller, which could damage the motor during the cutting process. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a practical and reliable feeding roller transmission mechanism.
[0004] To achieve the above objectives, the present invention provides a feeding roller transmission mechanism, comprising a frame, an upper clamping roller, and a lower clamping roller. The lower clamping roller is rotatably connected to the frame. The upper and lower clamping rollers are arranged vertically opposite each other. A first lifting cylinder is provided on the left and right sides of the frame, and each first lifting cylinder is connected downward to a first lifting seat. Each first lifting seat is connected to a rotating seat. The two rotating seats are rotatably connected to the upper clamping roller. An electromagnetic clutch is connected to one end of the upper clamping roller. A drive motor is provided on the rotating seat, and the drive motor is connected to the electromagnetic clutch.
[0005] The beneficial effects of this utility model are as follows: it effectively prevents damage to the upper clamping roller or motor. The transmission mechanism realizes the feeding of steel coil by setting an upper clamping roller and a lower clamping roller. Then, by setting two first lifting cylinders, it drives the upper clamping roller to move up and down. With the electromagnetic clutch connecting the upper clamping roller and the drive motor, it is possible to require the upper clamping roller and the lower clamping roller to press down when cutting some materials. The setting of the electromagnetic clutch can separate the drive motor from the upper clamping roller. When the upper clamping roller rotates, it will not drive the drive motor to rotate, thereby damaging the upper clamping roller or the motor. It effectively protects the upper clamping roller or the drive motor. The overall structure is practical and reliable.
[0006] Furthermore, lifting slots are respectively opened on the left and right sides of the frame, and both lifting slots extend vertically, with the first lifting seat slidably connected inside the lifting slots.
[0007] Furthermore, each end of the upper pinch roller is provided with a rotating shaft, which is rotatably connected to a rotating seat, and one of the rotating shafts is connected to an electromagnetic clutch.
[0008] Furthermore, the rotating seat is provided with brushes, which are connected to an electromagnetic clutch.
[0009] Furthermore, a bracket is provided on the rotating seat, the brush is provided on the bracket, and a transmission gear is rotatably connected to the bracket.
[0010] Furthermore, a pressure roller is slidably connected to the frame, the pressure roller is arranged horizontally, and the pressure roller is located directly above the upper pinch roller.
[0011] Furthermore, sliding seats are slidably connected to the left and right sides of the frame, and the two sliding seats are connected to the pressure roller together.
[0012] Furthermore, each of the two sliding seats is equipped with a second lifting cylinder. The second lifting cylinder is vertically positioned and connected downwards to a connecting block, which is connected to the machine frame. The two second lifting cylinders work together to drive the pressure roller to move up and down. With the above structure, this invention enables the pressure roller to move up and down, in conjunction with the upper pinch roller. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0018] See appendix Figure 1 To be continued Figure 2 As shown, a feeding roller transmission mechanism includes a frame 1, an upper clamping roller 2, and a lower clamping roller 3. The lower clamping roller 3 is rotatably connected to the frame 1. The upper clamping roller 2 and the lower clamping roller 3 are arranged vertically opposite each other. First lifting cylinders 11 are respectively arranged on the left and right sides of the frame 1. Each first lifting cylinder 11 is connected downward to a first lifting seat 111. Each first lifting seat 111 is connected to a rotating seat 12. The two rotating seats 12 are rotatably connected to the upper clamping roller 2. One end of the upper clamping roller 2 is connected to an electromagnetic clutch 13. A drive motor 14 is arranged on the rotating seat 12. The drive motor 14 is connected to the electromagnetic clutch 13.
[0019] In this embodiment, lifting slots 15 are respectively opened on the left and right sides of the frame 1. Both lifting slots 15 extend vertically, and the first lifting seat 111 is slidably connected inside the lifting slots 15.
[0020] In this embodiment, the upper clamping roller 2 is provided with a rotating shaft 21 at both ends, and the rotating shaft 21 is rotatably connected to the rotating seat 12, one of the rotating shafts 21 being connected to the electromagnetic clutch 13.
[0021] In this embodiment, a brush 122 is provided on the rotating seat 12, and the brush 122 is connected to the electromagnetic clutch 13; a bracket 121 is provided on the rotating seat 12, the brush 122 is provided on the bracket 121, and a transmission gear 123 is rotatably connected to the bracket 121.
[0022] In this embodiment, a pressure roller 18 is slidably connected to the frame 1. The pressure roller 18 is arranged horizontally and is located directly above the upper clamping roller 2. Sliding seats 16 are slidably connected to the left and right sides of the frame 1, and the two sliding seats 16 are connected to the pressure roller 18. A second lifting cylinder 17 is provided on each of the two sliding seats 16. The second lifting cylinder 17 is arranged vertically and is connected downward to a connecting block 171. The connecting block 171 is connected to the frame 1. The two second lifting cylinders 17 are used to drive the pressure roller 18 to move up and down together.
[0023] In this embodiment, the specific usage process is as follows: during normal material cutting, the two first lifting cylinders 11 are activated, and the piston rods of the two first lifting cylinders 11 retract to drive the lifting seat 111 and the rotating seat 12 to move upward, thereby raising the upper clamping roller 2 and moving the upper clamping roller 2 away from the lower clamping roller 3, that is, the upper clamping roller 2 and the lower clamping roller 3 are separated. However, some materials require the upper clamping roller 2 and the lower clamping roller 3 to be pressed together during the cutting process in order to be neatly rolled up. If the upper clamping roller 2 and the lower clamping roller 3 are pressed together, in the existing technology, when the steel coil and other materials are being rolled up and pulled along, the upper clamping roller 2 cannot be rotated because the motor is locked, which may damage the upper clamping roller 2 or the motor.
[0024] To solve this problem, this embodiment uses an electromagnetic clutch 13 instead of a conventional coupling. When feeding is required, the electromagnetic clutch 13 is closed and the upper clamping roller 2 can rotate. When feeding is not required, the electromagnetic clutch 13 is opened and the drive motor 14 can drive the upper clamping roller 2 to rotate.
[0025] When the pressure roller 18 is required to assist in its use, the second lifting cylinder 17 is activated. The piston rod of the second lifting cylinder 17 retracts, thereby driving the sliding seat 16 and the pressure roller 18 to move downwards, so that the pressure roller 18 assists the upper clamping roller 2.
[0026] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Any person skilled in the art can make more possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, all equivalent changes made based on the concept of this utility model without departing from the content of the technical solution of this utility model should be covered within the protection scope of this utility model.
