Description

Technical Field

[0001] The invention relates to the technical field of roller rolling machines, in particular to a guide roller for a twenty-roller rolling machine with a speed measuring structure. Background Art

[0002] At present, the speed of the twenty-high rolling mill depends on the speed of the rolling mill guide roller. The guide roller is driven by a variable frequency motor with an encoder to detect the running speed of the motor. The purpose of using the motor to drive the guide roller is to use the motor to overcome the rotational inertia of the guide roller, especially in the acceleration and deceleration process, to avoid the speed difference between the guide roller and the rolling mill, which will cause scratches on the strip surface.

[0003] However, since the motor and guide roller are connected by a flat key, there is a certain assembly gap in the flat key. During the acceleration and deceleration process, the gap will produce a certain speed difference. When rolling extremely thin strip steel, a small speed difference will affect the stability of the tension, causing the tension to fluctuate and cause the strip to break.

[0004] In view of the above problems, an improved guide roller for a twenty-roller rolling machine with a speed measuring structure is now designed. Summary of the invention

[0028] The fixing mechanism includes a plurality of internally threaded fixing cylinders 6, which are installed on the mounting cylinder 7 in a circular array. The internally threaded fixing cylinder 6 is arranged on a side of the rotating seat 3 away from the center of the rotating cylinder 1. The inner wall of the internally threaded fixing cylinder 6 is rotatably connected to a threaded rod 21 through a thread. One end of the threaded rod 21 close to the rotating roller 2 passes through the internally threaded fixing cylinder 6 and is rotatably connected to a clamping block 22 for clamping and fixing the rotating roller 2. One end of the threaded rod 21 away from the clamping block 22 passes through the internally threaded fixing cylinder 6 and is installed with a gear 5 for driving the threaded rod 21 to rotate. A driving component for uniformly driving all the gears 5 to rotate is provided on the mounting cylinder 7.

[0029] The driving assembly includes a second rotating ring 9, which is rotatably connected to the side wall of the mounting tube 7. The second rotating ring 9 is arranged at one end of the mounting tube 7 away from the center of the rotating tube 1. A gear ring 10 used in conjunction with the gear 5 is installed at the end of the second rotating ring 9 close to the gear 5. The gear ring 10 and the gear 5 are meshed with each other. The length of the teeth on the gear ring 10 is greater than the length of the teeth on the gear 5. The end of the second rotating ring 9 away from the rotating seat 3 is provided with a plurality of sockets 13 in a circular array for the convenience of the staff to use a pin rod to rotate the second rotating ring 9.

[0030] When in use, the staff inserts the pin rod into the socket 13, and then rotates the second rotating ring 9 through the pin rod, the second rotating ring 9 drives the gear ring 10 to rotate, the gear ring 10 drives the gear 5 to rotate, the gear 5 drives the threaded rod 21 to rotate, and under the action of the thread, the threaded rod 21 drives the clamping block 22 to move, so that the clamping block 22 is clamped and fixed on the side wall of the rotating roller 2.

[0031] The rotating mechanism includes a plurality of inclined plates 14, which are installed in a circular array on the inner wall of the rotating cylinder 1 on the side of the mounting cylinder 7 close to the rotating seat 3. A plurality of baffles 11 corresponding to the inclined plates 14 are installed on the side wall of the mounting cylinder 7. The baffles 11 have the same inclination angle as the inclined plates 14, and the inclination direction of the baffles 11 is the same as the conveying direction of the strip steel of the rotating cylinder 1. The lower end of the side wall of the baffle 11 close to the corresponding inclined plate 14 is rotatably connected with a swing plate 15 used in conjunction with the inclined plate 14 through a hinge. When the rotating roller 2 accelerates, the swing plate 15 pushes the inclined plate 14 to rotate. A spring 16 for pushing the swing plate 15 to swing toward the baffle 11 is installed on the side wall of the swing plate 15 away from the baffle 11, and the end of the spring 16 away from the swing plate 15 is installed on the side wall of the mounting cylinder 7.

[0032] When the rotating roller 2 accelerates, the rotating roller 2 drives the mounting cylinder 7 to rotate, the mounting cylinder 7 drives the baffle 11 and the swing plate 15 to rotate, the swing plate 15 drives the inclined plate 14 to rotate, and the inclined plate 14 drives the rotating cylinder 1 to rotate.

[0033] When the rotating roller 2 decelerates, the rotating cylinder 1 continues to rotate under the action of inertia, the inclined plate 14 contacts the side wall of the swing plate 15 close to the baffle 11, and pushes the swing plate 15 to swing, the swing plate 15 compresses the spring plate 16, and then the inclined plate 14 passes over the swing plate 15 and continues to rotate until the rotation speed of the rotating cylinder 1 is the same as that of the rotating roller 2 and the mounting cylinder 7, so that the rotating roller 2 and the mounting cylinder 7 drive the rotating cylinder 1 to rotate again.

[0034] The speed measuring mechanism includes an encoder 18, which is installed on the upper end of the bearing seat 17 on the side of the rotating roller 2 away from the driving end. A rotating disk 20 is installed at the detection end of the encoder 18, and a rubber ring 19 is installed on the side wall of the rotating disk 20. A plurality of friction bumps 12 are installed in a circular array at one end of the rotating cylinder 1 close to the encoder 18 to facilitate the rotation of the rubber ring 19.

[0035] When the rotating drum 1 rotates, the rotating drum 1 drives the friction protrusion 12 to rotate, the friction protrusion 12 drives the rubber ring 19 to rotate, and the rubber ring 19 drives the rotating disk 20 to rotate, so that the encoder 18 measures various data of the rotating drum 1 and uploads them to the control system.

[0036] Working principle of a guide roller for a twenty-roller rolling machine with a speed measuring structure:

[0037] During installation, the installation tube 7 is sleeved on the side wall of the rotating roller 2, and then the staff inserts the pin rod into the inside of the socket 13, and then rotates the second rotating ring 9 through the pin rod, the second rotating ring 9 drives the gear ring 10 to rotate, the gear ring 10 drives the gear 5 to rotate, and the gear 5 drives the threaded rod 21 to rotate. Under the action of the thread, the threaded rod 21 drives the clamping block 22 to move, so that the clamping block 22 is clamped and fixed on the side wall of the rotating roller 2, thereby fixing the installation tube 7 on the side wall of the rotating roller 2.

[0038] When in use, the driving end motor drives the rotating roller shaft 8 and the rotating roller 2 to rotate. When the rotating roller 2 accelerates or rotates at a constant speed, the rotating roller 2 drives the mounting cylinder 7 to rotate, and the mounting cylinder 7 drives the baffle 11 and the swing plate 15 to rotate. The swing plate 15 drives the inclined plate 14 to rotate, and the inclined plate 14 drives the rotating cylinder 1 to rotate.

[0039] When the rotating roller 2 decelerates, the rotating cylinder 1 continues to rotate under the action of inertia, the inclined plate 14 contacts the side wall of the swing plate 15 close to the baffle 11, and pushes the swing plate 15 to swing, the swing plate 15 compresses the spring plate 16, and then the inclined plate 14 passes over the swing plate 15 and continues to rotate until the rotation speed of the rotating cylinder 1 is the same as that of the rotating roller 2 and the mounting cylinder 7, so that the rotating roller 2 and the mounting cylinder 7 drive the rotating cylinder 1 to rotate again.

[0040] When the rotating drum 1 rotates, the rotating drum 1 drives the friction protrusion 12 to rotate, the friction protrusion 12 drives the rubber ring 19 to rotate, and the rubber ring 19 drives the rotating disk 20 to rotate, so that the encoder 18 measures various data of the rotating drum 1 and uploads it to the control system to regulate the speed of the twenty-roll mill.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
