[0025] To make the objectives, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present invention.

[0026] The present invention provides a mill roll gap adjusting device to solve the technical problem of online adjusting the roll gap of the mill. The mill roll gap adjusting device includes a machine body 1, a roll 2, a slider 3, a driving motor 4 and a speed reducer 5, wherein:

[0027] The machine body 1 is used to form a frame for supporting other components, so that other components can be installed on the machine body 1. The machine body 1 is fixed to the ground to reduce the shaking of the machine body 1 during use.

[0028] There are two rolls 2. The two rolls 2 are rotatably installed on the machine body 1. The rolls 2 rotate to facilitate the passage of the metal to be rolled. The two rolls 2 are arranged in parallel so that the distance between the two rolls 2 is always equal. When the metal passes between the two rolls 2, the two rolls 2 can roll the metal into the same size. A roll gap is formed between the two rolls 2. The metal to be rolled enters the roll gap from one side of the roll gap, and then is discharged from the other side of the roll gap after being rolled by the two rolls 2 to complete one rolling of the metal. Optionally, multiple groups of rolls 2 can be arranged along the moving direction of the metal. The multiple groups of rolls 2 are parallel to the above two rolls 2 to roll the metal to be rolled multiple times to make the size of the rolled metal more consistent. It is also possible to make the roll gaps between the multiple groups of rolls 2 gradually decrease along the moving direction of the metal to gradually roll the metal into the required size.

[0029] A chute is provided on the machine body 1. To facilitate the rolling of the metal, the two rolls 2 in this embodiment are arranged vertically. The chute extends vertically. The number of chutes is two. The rolls 2 are located between the two chutes. The slider 3 is slidably installed in the chute. The slider 3 corresponds to the chute one by one. Both ends of any roll 2 are rotatably installed on the two sliders 3. The two sliders 3 move to drive the roll 2 to move along the axial direction of the chute. The two sliders 3 move synchronously to keep the two rolls 2 always parallel to roll the metal through the rolls 2.

[0030] The driving motor 4 is in transmission connection with the rolling rolls 2. The driving motor 4 is used to output power and transmit the output power to the rolling rolls 2, so as to drive the rolling rolls 2 to rotate. When the metal to be rolled passes between the two rolling rolls 2, the rotation of the rolling rolls 2 is used to drive the metal to move. The driving motor 4 drives at least one rolling roll 2 to rotate, and the other rolling roll 2 rotates along with the movement of the metal. When driving the two rolling rolls 2 to rotate, the rotation directions of the two rolling rolls 2 are opposite, so that when the rolling rolls 2 roll the metal, the rolling rolls 2 can drive the metal to move in the same direction, thereby completing the rolling of the metal.

[0031] The speed reducer 5 is installed between the driving motor 4 and the rolling rolls 2. One end of the speed reducer 5 is in transmission connection with the driving motor 4, and the other end is in transmission connection with the rolling rolls 2. When the driving motor 4 rotates, it drives the rolling rolls 2 to rotate after being decelerated by the speed reducer 5, thereby slowing down the rotation speed of the rolling rolls 2, and further making the torque of the rolling rolls 2 larger, so that the rolling rolls 2 can rotate to roll the metal. At the same time, when rolling the metal, it reduces the reduction of the rolling quality of the metal caused by the too fast rotation of the rolling rolls 2 resulting in too fast movement of the metal, and also reduces the movement speed of the metal, making it safer to use.

[0032] With the above structure, when a rolling mill roll gap adjusting device provided by the present invention needs to roll metal, first, according to the size of the metal and the size to which the metal needs to be rolled, the slider 3 is slid along the chute to adjust the position of the slider 3 in the chute, thereby changing the distance between the two rolling rolls 2. By measuring the distance between the two rolling rolls 2, the width of the roll gap is adjusted to the width required during metal rolling. Then, the driving motor 4 outputs power, and after being decelerated by the speed reducer 5, the power is transmitted to the rolling rolls 2 to drive the rolling rolls 2 to rotate. The metal to be rolled passes between the two rolling rolls 2 and moves from one side of the roll gap to the other side under the drive of the rolling rolls 2, completing the rolling of the metal. Therefore, the rolling mill roll gap adjusting device adjusts the width of the roll gap by moving the slider 3 according to the size of the metal to be rolled when the rolling rolls 2 stop rotating, thereby reducing the operation time of the rolling mill and improving the production efficiency of the rolling mill.

[0033] An optional implementation manner of this embodiment is as follows: In order to facilitate the movement of the rolling rolls 2, the rolling mill roll gap adjusting device further includes a screw rod 6. The screw rod 6 is rotatably installed in the chute, and the axial direction of the screw rod 6 is arranged along the extension direction of the chute. The slider 3 is screwed onto the screw rod 6, and the slider 3 moves along the axial direction of the screw rod 6. When the slider 3 slides, the outer wall of the slider 3 abuts against the groove wall of the chute. When the screw rod 6 rotates, since the groove wall of the chute blocks the slider 3 from rotating along with the screw rod 6, the slider 3 can only move along the screw rod 6, thereby driving the slider 3 to move in the chute; it should be noted that there are two screw rods 6 and sliders 3. When the slider 3 moves, the two screw rods 6 rotate synchronously, thereby driving the two sliders 3 to move in the same direction, and further keeping the two rolling rolls 2 parallel.

[0034] An optional implementation of this embodiment is as follows: In order to better fix the position of the slider 3, the rolling mill roll gap adjustment device also includes a worm gear, which is installed on the machine body 1, and the worm gear 7 is connected to the screw 6 in a transmission manner. The worm gear rotates, thereby driving the screw 6 to rotate. Since the worm gear has a self-locking property, the rotation of the screw 6 is resisted by the worm gear, so that the worm gear 7 can only drive the screw 6 to rotate in one direction. Specifically, the turbine is installed on the screw 6, and the turbine is fixedly connected to the screw 6, thereby driving the screw 6 to rotate when the turbine rotates. The worm is meshed with the turbine, and the worm rotates, thereby driving the turbine to rotate. The worm can be driven by a motor or the like, or it can be driven manually.

[0035] An optional implementation of the present embodiment is as follows: in order to make the two screw rods 6 rotate synchronously, the rolling mill roll gap adjustment device also includes a transmission shaft, and the two ends of the transmission shaft are respectively connected to the two screw rods 6 for transmission. The two ends of the transmission shaft can be connected by gears or the like. It is worth noting that when the two ends of the transmission shaft are connected to the screw rods 6, they should have the same transmission ratio so that the transmission shaft can make the two screw rods 6 rotate synchronously.

[0036] An optional implementation of the present embodiment is as follows: in order to make the two screw rods 6 rotate synchronously, the rolling mill roll gap adjustment device also includes a transmission chain, which is connected to the two screw rods 6. Specifically, a sprocket is provided at the same end of the two screw rods 6, and the sprocket is fixedly connected to the screw rods 6. The transmission chain is meshed with the sprocket. When one of the screw rods 6 rotates, the other screw rod 6 is driven by the transmission chain.

[0037] An optional implementation of this embodiment is as follows: In order to facilitate the connection between the machine body 1, the reducer 5 and the drive motor 4, the rolling mill roll gap adjustment device also includes a base 8, which is arranged below the drive motor 4, the reducer 5, the machine body 1 and the base 8. The base 8 corresponds to the drive motor 4, the reducer 5 and the machine body 1 one by one. The base 8 is used to support the drive motor 4, the reducer 5 and the machine body 1, increase the stability of the drive motor 4, the reducer 5 and the machine body 1, reduce the impact of shaking during use on the quality of the metal during metal rolling, and at the same time, the drive motor 4, the reducer 5 and the machine body 1 are raised to facilitate the connection between the drive motor 4, the reducer 5 and the machine body 1.

[0038] An optional implementation of this embodiment is as follows: In order to facilitate the connection between the reducer 5 and the drive motor 4, the rolling mill roll gap adjustment device also includes a coupling 9, which is used to connect the drive motor 4 to the reducer 5 and rotate together, and transmit motion and torque.

[0039] An alternative implementation of this embodiment is as follows: There are two speed reducers 5 in total. The two speed reducers 5 are connected by a coupling 9 for transmission. Through the gear transmission of the two speed reducers 5, the reduction ratio is increased, thereby outputting a lower rotational speed. At the same time, the torque is increased, thereby improving the load capacity and transmission reliability of the rolling mill 2.

[0040] An alternative implementation of this embodiment is as follows: The coupling 9 is a drum gear coupling 9. The drum gear coupling 9 is suitable for heavy-duty scenarios to better suit the rolling of metals by the rolling mill.

[0041] As described above, only the specific implementation manners of the present invention are provided, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope recorded in the present invention can easily think of changes or substitutions, which should all be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
