Description

Technical Field

[0001] This utility model relates to the field of rolling mills, specifically a multi-roll rolling mill for non-ferrous metal rolling. Background Technology

[0002] A rolling mill is a key piece of equipment used for rolling metal materials. It uses a multi-roll structure to extrude and stretch metal billets to adjust thickness or improve surface quality. In practical applications, metal billets are prone to displacement or surface adhesion of impurities during the rolling process due to uneven stress, affecting the quality of the finished product. Traditional rolling mills typically use a fixed roller layout, lacking dynamic adjustment capabilities, resulting in unstable material handling and difficulty in adapting to the rolling requirements of different materials.

[0003] Publication number CN221361888U describes a multi-roll calender for non-ferrous metal rolling. It employs a hydraulically driven arched pressure seat in conjunction with pressure rollers for rolling, and a V-shaped scraper is installed at the bottom of the positioning roller. Simultaneously, a folded scraper is installed inside the arched pressure seat to clean impurities adhering to the roller surface. This design reduces impurity accumulation through mechanical scraping, thus improving rolling quality to some extent.

[0004] However, when multiple rollers in a calender are working, the material will deviate to a certain extent when it is transferred between the rollers because the rotation speed and placement of the rollers are different. Therefore, it cannot be guaranteed that the material will remain in the positive position for a long time during calendering. Furthermore, when the material deviates, the calendering rollers will also damage the surface of the material.

[0005] Therefore, a multi-roll rolling mill for non-ferrous metal rolling is proposed to solve the problems mentioned above. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] A multi-roll rolling mill for non-ferrous metal rolling includes a frame 1, a control box 2 at one end of the frame 1, a motor assembly 4 at the upper end of one side of the frame 1, a drive roller 7 through the motor assembly 4 at one side of the upper end of the frame 1, a second single-sided roller 10 at one side of the drive roller 7, and a first single-sided roller 6 at the other side of the drive roller 7. A top plate 5 is provided at the middle of the top of the frame 1. A triangular roller 3 is rotatably provided at the upper inner side of the top plate 5. A spring 18 is connected between the middle of the upper outer side of the triangular roller 3 and the bottom of the top plate 5. A connecting rod 14 is horizontally provided through the bottom of the triangular roller 3. A guide rod 16 is provided on one side of the connecting rod 14. A gear 15 is provided at one end of the guide rod 16. A transmission wheel 13 is provided on the outer side of the frame 1 near the first single-sided roller 6. A half-cut toothed plate 17 is provided on the side of the transmission wheel 13 near the guide rod 16. A rotating wheel 12 is provided at one end of the transmission wheel 13. A transmission belt 11 is sleeved between the drive roller 7, the transmission wheel 13, the second single-sided roller 10, and the rotating wheel 12. A curved arm assembly 9 is provided on the front of the second single-sided roller 10. A prismatic shaft 8 is provided at one end of the curved arm assembly 9.

[0020] Among them, a transmission belt 11 is sleeved on one end of the drive roller 7 and the transmission wheel 13, so the drive roller 7 can drive the transmission wheel 13 to rotate when it rotates. A transmission belt 11 is fitted onto one end of the second single-sided roller 10 and the rotating wheel 12. Therefore, when the rotating wheel 12 rotates synchronously with the transmission wheel 13, it can drive the second single-sided roller 10 to rotate.

[0021] Example 1: Please refer to Figure 1 - Figure 6 The frame 1 has a control box 2 at one end. The control box 2 drives the motor assembly 4 to work. The motor assembly 4 drives the drive roller 7 to rotate. The drive roller 7 has a first single-sided roller 6 and a second single-sided roller 10 on both sides. The three are closely arranged to form a triangular structure. The drive roller 7 is located at the highest point. When the material passes through the second single-sided roller 10, the drive roller 7, and the first single-sided roller 6, the drive roller 7 rotates actively. The material is moved by force and pushes the first single-sided roller 6 and the second single-sided roller 10 to rotate, thereby achieving extrusion and stretching. The control box 2 is pre-installed with a controller for starting and stopping the motor assembly 4, and the control box 2 is also equipped with relevant buttons for operation. When the user presses the relevant button on the outside of the control box 2, the controller inside the control box 2 sends a command signal to the motor assembly 4, thereby causing the motor assembly 4 to start working or stop working.

[0022] The drive roller 7 drives the transmission wheel 13 to rotate via the conveyor belt 11. The half-tooth plate 17 on the back of the transmission wheel 13 intermittently meshes with the gear 15. The gear 15 drives the guide rod 16 to rotate. The guide rod 16 is fixedly connected to the connecting rod 14. The connecting rod 14 drives the triangular roller 3 to move down at the bottom of the top plate 5. The spring 18 assists in resetting. The triangular roller 3 intermittently presses down on the material to prevent deviation. The transmission wheel 13 also drives the auxiliary wheel of the second single-sided roller 10 to rotate via the rotating wheel 12 and the conveyor belt 11. The auxiliary wheel drives the crank arm assembly 9 to move back and forth. The crank arm assembly 9 pushes the material obliquely through the prism shaft 8 to accelerate the calendering effect. In addition, the half-tooth plate 17 can be replaced with a cam structure, which directly pushes the connecting rod 14 to move up and down, simplifying the transmission chain. The connection between the guide rod 16 and the connecting rod 14 can be changed to a hinge, increasing flexibility.

[0023] Example 2: Please refer to Figure 1 - Figure 6 The top of the frame 1 is provided with a top plate 5. A triangular roller 3 is rotatably installed on the inner side of the top plate 5. The triangular roller 3 is connected to the top plate 5 through a shaft. The shaft can drive the triangular roller 3 to rotate. The drive roller 7 drives the transmission wheel 13 and the rotating wheel 12 to rotate through the transmission belt 11. The rotating wheel 12 drives the auxiliary wheel of the second single-sided roller 10 through the transmission belt 11. The auxiliary wheel drives the crank arm assembly 9 to move. The crank arm assembly 9 pushes the material obliquely through the prismatic shaft 8. The length of the prismatic shaft 8 is the same as that of the second single-sided roller 10 to ensure uniform thrust. The half-tooth plate 17 of the transmission wheel 13 meshes with the gear 15. The gear 15 drives the guide rod 16 to rotate. The guide rod 16 is fixedly connected to the connecting rod 14. The connecting rod 14 drives the triangular roller 3 to press down the material. The spring 18 helps the triangular roller 3 to return to its original position. The second single-sided roller 10 and the first single-sided roller 6 are on the same straight line to ensure that the material is subjected to force in a balanced manner. In addition, the conveyor belt 11 can be replaced with a chain drive to improve transmission efficiency, and the crank arm assembly 9 can be replaced with a linear motor drive to directly control the pushing frequency and amplitude of the prism shaft 8, thereby improving accuracy.

[0024] When in use, start the control box 2, and the control box 2 drives the motor assembly 4 to work. The motor assembly 4 drives the drive roller 7 to rotate. The user can place the material along the outside of the second single-sided roller 10, the drive roller 7, and the first single-sided roller 6. At this time, the motor assembly 4 will drive the drive roller 7 to rotate actively, and the material moves under the force outside the drive roller 7. Therefore, the first single-sided roller 6 and the second single-sided roller 10 are rotated by the pushing force of the material. Since the first single-sided roller 6, the drive roller 7, and the second single-sided roller 10 are closely arranged, the material will be squeezed and stretched. When the drive roller 7 rotates, it drives the corresponding conveyor belt 11 to rotate, the conveyor belt 11 drives the transmission wheel 13 to rotate, the half-tooth plate 17 on the back of the transmission wheel 13 rotates, the half-tooth plate 17 intermittently drives the gear 15 to rotate, the gear 15 drives the guide rod 16 to rotate, the guide rod 16 drives the connecting rod 14 to rotate, and the connecting rod 14 drives the triangular roller 3 to move downward in an arc at the bottom of the top plate 5. The spring 18 helps the triangular roller 3 to reset. When the triangular roller 3 moves downward, it intermittently abuts against the outside of the material being squeezed. This allows the material to be fully rolled by the first single-sided roller 6, the drive roller 7 and the second single-sided roller 10, preventing the material from shifting. When the drive wheel 13 rotates, the drive wheel 13 drives the rotating wheel 12 to rotate, the rotating wheel 12 drives the corresponding conveyor belt 11 to rotate, the conveyor belt 11 drives the external auxiliary wheel of the second single-side roller 10 to rotate independently, the auxiliary wheel drives the crank arm assembly 9 to move back and forth, the crank arm assembly 9 drives the prism shaft 8 to continuously push the material being rolled out obliquely forward, thereby accelerating the material processing effect.

[0025] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
