Description

Technical Field

[0001] This application relates to the field of aluminum rod rolling equipment, and more particularly to a take-up mechanism based on an aluminum rod rolling mill. Background Technology

[0002] Aluminum rod rolling mills are widely used in the processing and production of aluminum materials. During the aluminum rod production process, the finished aluminum rods produced by the rolling mill are transported to the take-up frame via a take-up guide device to be wound into coils for easy storage and transportation. The take-up mechanism, as a key component of the rolling mill, plays the role of winding the aluminum rods into coils.

[0003] Chinese Patent CN203470549U discloses a copper rod winding guide device for a copper rod rolling mill, comprising a guide tube and a guide tube support. The guide tube support is fixed to the ground, and the guide tube is fixed to the top surface of the guide tube support. This design guides the copper rod through the guide tube, enabling it to be smoothly wound onto the winding rollers of the winding device.

[0004] However, because the take-up roller has a certain length, the coil diameter near the guide tube is relatively large, resulting in uneven winding. Summary of the Invention

This, in turn, synchronously drives the guide assembly to reciprocate along the axial direction of the take-up roller, ensuring the aluminum rod is evenly wound onto it. Because the bidirectional lead screw and take-up roller move synchronously, the guide assembly also adjusts its position accordingly when the winding speed increases or decreases, ensuring even winding of the aluminum rod.

[0037] This application discloses a take-up mechanism based on an aluminum rod rolling mill.

[0038] Reference Figure 1 A take-up mechanism based on an aluminum rod rolling mill includes a frame 1, a take-up roller 11, a power assembly and a tensioning assembly 8. The take-up roller 11 is rotatably mounted on the frame 1, and guide wheels 2 are provided at both ends of the tensioning assembly 8.

[0039] Among them, reference Figure 1 and Figure 2The power assembly is connected to the frame 1 and is used to drive the take-up roller 11 to rotate so as to wind the aluminum rod onto the take-up roller 11. Specifically, the power assembly includes a power motor 3, which is fixedly mounted on the frame 1. The power motor 3 can be a servo motor. The power motor 3 is connected to the take-up roller 11 for transmission. In this embodiment, the output shaft of the power motor 3 is coaxially and fixedly connected to the take-up roller 11.

[0040] Reference Figure 1 and Figure 2 A movable block 4 is slidably disposed on the frame 1 along the axial direction of the take-up roller 11. A guide assembly 5 is disposed on the movable block 4 to guide the aluminum rod to move along the movable block 4.

[0041] Reference Figure 2 and Figure 3 The guide assembly 5 includes a mounting plate 51, a receiving roller 52, and a limiting assembly. The mounting plate 51 is fixedly mounted on the moving block 4. The receiving roller 52 is horizontally rotatably mounted on the mounting plate 51. At least two receiving rollers 52 are provided. The receiving roller 52 is parallel to the take-up roller 11. The receiving roller 52 serves to receive the aluminum rod and reduce the downward bending deformation of the aluminum rod due to gravity. After being guided by the receiving roller 52, the aluminum rod is wound onto the take-up roller 11.

[0042] In this embodiment, the limiting component is disposed between the two receiving rollers 52 for clamping the aluminum rod.

[0043] Specifically, refer to Figure 3 The limiting component includes two pressure rollers 53, which are rotatably mounted on the mounting plate 51 for contact with the aluminum rod. The two pressure rollers 53 are located on both sides of the aluminum rod, and the rotation axes of the pressure rollers 53 are perpendicular to the axis of the aluminum rod. The two pressure rollers 53 contact both sides of the aluminum rod to position it, thereby controlling the winding position of the aluminum rod and ensuring that it is wound evenly on the winding roller 11.

[0044] Optional, refer to Figure 3The pressure roller 53 is slidably mounted on the mounting plate 51 along the axial direction of the take-up roller 11. The mounting plate 51 is equipped with an adjustment assembly 6 for adjusting the distance between the two pressure rollers 53. In this embodiment, the adjustment assembly 6 includes an adjustment screw 61 and an adjustment block 62. An adjustment plate 511 is fixedly mounted on the mounting plate 51 along a length direction parallel to the receiving roller 52. An adjustment groove 5111 is formed on the top wall of the adjustment plate 511, extending along its length. The adjustment block 62 is slidably mounted within the adjustment groove 5111. The adjustment groove 5111 can be a T-groove or a dovetail groove. The adjustment block 62 is adapted to the adjustment groove 5111 and can be a T-shaped block or a dovetail block. Two adjustment blocks 62 are provided, and the pressure roller 53 is rotatably mounted on the adjustment block 62. The adjustment screw 61 rotatably passes through the adjustment groove 5111, with one end of the adjustment screw 61 extending out of the adjustment plate 511. The threads at both ends of the adjustment screw 61 rotate in opposite directions. To facilitate the rotation of the adjusting screw 61, a handheld device is fixedly installed at one end extending beyond the adjusting plate 511. The adjusting block 62 is threaded onto the adjusting screw 61. By rotating the adjusting screw 61, the two adjusting blocks 62 can be moved within the adjusting groove 5111, thereby causing the two pressure rollers 53 to move closer or further apart. The distance between the two pressure rollers 53 can be adjusted to accommodate aluminum rods of different sizes.

[0045] Reference Figure 2 A drive assembly 7 is mounted on the frame 1 to drive the moving block 4 to reciprocate along the length of the take-up roller 11, which is the axial direction of the take-up roller 11. The drive assembly 7 includes a bidirectional lead screw 71, a guide rod 72, and a drive source. The guide rod 72 is fixedly mounted on one end of the frame 1 near the take-up roller 11 and is parallel to the axial direction of the take-up roller 11. The bidirectional lead screw 71 is rotatably mounted on the frame 1 and is parallel to the guide rod 72, with the threads at both ends of the bidirectional lead screw 71 rotating in opposite directions. The moving block 4 is slidably sleeved on the bidirectional lead screw 71 and the guide rod 72, and is threadedly connected to the bidirectional lead screw 71.

[0046] Optional, refer to Figure 2The drive source is used to drive the bidirectional lead screw 71 to rotate. The drive source includes a transmission assembly 73, and the take-up roller 11 and the bidirectional lead screw 71 are connected by the transmission assembly 73. The transmission assembly 73 includes a first transmission wheel 731, a second transmission wheel 732, and a transmission belt 733. The first transmission wheel 731 is located at one end of the take-up roller 11, the second transmission wheel 732 is located at one end of the bidirectional lead screw 71, and the transmission belt 733 is sleeved on the first transmission wheel 731 and the second transmission wheel 732. During the winding process, the power motor 3 drives the take-up roller 11 to rotate synchronously, and then drives the second transmission wheel 732 and the bidirectional lead screw 71 to rotate through the transmission belt 733. This, in turn, synchronously drives the guide assembly 5 to reciprocate along the axial direction of the take-up roller 11, so that the aluminum rod can be evenly wound onto the take-up roller 11. Because the bidirectional lead screw 71 and the take-up roller 11 move synchronously, when the winding speed increases or decreases, the guide assembly 5 also increases or decreases synchronously, so that the aluminum rod can be wound evenly.

[0047] Optional, refer to Figure 1 and Figure 4 A tensioning assembly 8 is mounted on the frame 1 for tensioning the aluminum rod. The tensioning assembly 8 includes a fixed plate 81, a tensioning wheel 82, and an elastic element 83. The fixed plate 81 is vertically fixed on the frame 1, the tensioning wheel 82 is rotatably mounted on the fixed plate 81, and the elastic element 83 is mounted on the fixed plate 81 to drive the tensioning wheel 82 to press against the aluminum rod. A strip groove 811 is formed in the fixed plate 81 along its length, and a sliding block 812 is slidably mounted in the strip groove 811. The tensioning wheel 82 is rotatably mounted on the sliding block 812.

[0048] Reference Figure 4 A positioning block 813 is slidably disposed within the strip groove 811, positioned above the mounting base. The elastic element 83 is a compression spring, with one end abutting against the positioning block 813 and the other end abutting against the mounting base. An adjusting element, a lifting screw 814, is provided on the fixing plate 81 for adjusting the position of the positioning block 813. The lifting screw 814 is threaded vertically through the top wall of the fixing plate 81, and its bottom end is ball-jointed with the adjusting block 62. By rotating the lifting screw 814, the adjusting block 62 can be moved up and down within the strip groove 811 to adjust the preload of the compression spring.

[0049] The take-up mechanism also includes a pressure sensor for real-time detection of the aluminum rod pressure and outputting a detection signal. The pressure sensor can be positioned between the positioning block 813 and the compression spring to detect the spring pressure. A controller, electrically connected to the pressure sensor, generates a speed adjustment command based on the deviation between the detection signal and a preset pressure threshold, and controls the speed of the drive motor 3.

[0050] When the pressure sensor detects that the pressure is greater than the preset threshold, it means that the tension of the aluminum rod is too high. At this time, the controller controls the power motor 3 to reduce the speed and reduce the winding rate to reduce the pressure on the aluminum rod.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
