DETAILED DESCRIPTION

[0028] The following will be combined with the drawings Figures 1-7 The application will be further described in detail.

[0029] This application discloses a diameter adjustment device for a rolling machine.

[0030] like Figures 1-7 As shown, a diameter adjustment device for a rolling machine includes a rotating roller 104 and a connecting frame. A positioning mechanism is provided on the rotating roller 104. The positioning mechanism includes a circular groove 1040, a sliding column 3, a slider 4, and a threaded column 5. The slider 4 is rotatably connected in the circular groove 1040 and is inserted into the slot 30. The threaded column 5 is threadedly connected to the sliding column 3.

[0031] The connecting frame is equipped with a displacement mechanism, which includes a linear module 6, a synchronous dual-axis motor 8, a winding wheel 9, and a thick steel wire rope 10. The linear module 6 is equipped with a synchronous dual-axis motor 8, and the rotating ends of the synchronous dual-axis motor 8 are fixedly connected to the winding wheel 9. The thick steel wire rope 10 is wound on the winding wheel 9.

[0032] Please see Figures 1 to 3 It also includes a two-roll rolling machine 1, which consists of a motor 100, a rubber roller 101, a cylinder 102, a fixed roller 103, and a rotating roller 104. The motor 100 is fixedly connected to the rubber roller 101, and the fixed roller 103 is fixedly connected to the end of the output end of the cylinder 102. A rolling part 2 is placed between the rubber roller 101 and the rotating roller 104. Both the motor 100 and the cylinder 102 are externally powered. The motor 100 drives the rubber roller 101 to rotate, and the cylinder 102 drives the fixed roller 103 and the rotating roller 104. The roller moves up and down, placing the rolled piece 2 on the outer circumference of the rubber roller 101. The controller controls the fixed roller 103 and the rotating roller 104 to press down. At this time, the top and bottom surfaces of the rolled piece 2 contact the outer circumference of the rotating roller 104 and the rubber roller 101, respectively. The controller then controls the motor 100 to drive the rubber roller 101 to rotate. As the rubber roller 101 rotates, the rolled piece 2 drives the rotating roller 104 to rotate, thus completing the rolling process of the rolled piece 2. The two-roller rolling machine 1 is existing technology and will not be described in detail here.

[0033] Please see Figure 4 and Figure 6 A sliding groove 1030 extends through one side of the fixed roller 103. A sliding column 3 is inserted into the sliding groove 1030. A slot 30 is horizontally opened on the top of the sliding column 3. The slot 30 is connected to the threaded hole A31.

[0034] Please see Figure 4 and Figure 6A circular groove 1040 is provided on one side of the rotating roller 104. A slider 4 is rotatably connected in the circular groove 1040. The slider 4 is horizontally inserted into the slot 30. A threaded hole 40 is vertically passed through the slider 4. A threaded post 5 is threadedly connected to the threaded hole A31 and the threaded hole 40. During the process of the fixed roller 103 descending driven by the output end of the cylinder 102, the inner wall of the rotating roller 104 will fall onto the outer circumferential wall of the top of the fixed roller 103. The sliding post 3 moves up and down in the sliding groove 1030. The descent of the fixed roller 103 will cause the sliding post 3 and the circular groove 1040 to descend synchronously. The circular groove 1040 moves with the rubber roller. As roller 101 rotates, slider 4 rotates in circular groove 1040, keeping fixed roller 103 and sliding column 3 stationary, without affecting the normal rotation of roller 104. By unscrewing threaded column 5, roller 104 and slider 4 can be removed to replace roller 104 and threaded column 5 with rollers 104 and threaded column 5 of different diameters. The threaded column 5 connects roller 104 and sliding column 3. The setting of sliding column 3, slider 4 and threaded column 5 ensures that roller 104 is in a fixed position during rotation, avoiding the instability of placing it directly on fixed roller 103 without sliding column 3, slider 4 and threaded column 5.

[0035] Please see Figures 1 to 3 A connecting frame is fixedly connected to the top surface of the operating table of the two-roll rolling machine 1. A linear module 6 is installed on the connecting frame. A support platform 7 is fixedly connected to the bottom of the sliding end of the linear module 6. A synchronous dual-axis motor 8 is installed on the support platform 7.

[0036] Please see Figure 7 A connecting ball 11 is fixedly connected to the end of the thick steel wire rope 10. A ball hole 110 is opened in the connecting ball 110, and a universal ball 12 is rotatably connected in the ball hole 110. A thin steel wire rope 13 is fixedly connected to the universal ball 12. After the coiling part 2 is coiled, the operator controls the sliding end of the linear module 6 to slide horizontally, and simultaneously controls the synchronous dual-axis motor 8 to rotate, so that the winding wheel 9 rotates synchronously to release the thick steel wire rope 10. The operator then inserts the falling "C"-shaped part 14 into both ends of the coiling part 2 and tightens the screws 15 in sequence, so that the outer wall and inner wall of the coiling part 2 contact the pressure plate 16 and the bottom top surface of the "C"-shaped part 14. The operator then uses the controller to slide the sliding end of the linear module 6 out, so that the coiling part 2 moves horizontally off the rotating roller 104. When it is completely removed from the rotating roller 104, the linear module 6 stops working, and the synchronous dual-axis motor 8 is controlled to release the wire so that the coiling part 2 falls onto the trolley.

[0037] Please see Figure 7A C-shaped component 14 is fixedly connected to the end of the thin steel wire rope 13. A screw 15 is threadedly connected to the top of the C-shaped component 14. A pressure plate 16 is fixedly connected to the end of the screw 15. A rolled component 2 is clamped between the inner wall of the bottom surface of the C-shaped component 14 and the bottom surface of the pressure plate 16. Both the linear module 6 and the support platform 7 are externally powered. The single set of thick steel wire rope 10 and thin steel wire rope 13 are of equal length, mainly to enable the rolled component 2 to move horizontally and avoid the rolled component 2 from touching the rotating roller 104 due to tilting. Both the linear module 6 and the support platform 7 are controlled by a controller. The controller structure is not shown in the figure.

[0038] The implementation principle of the diameter adjustment device for a rolling machine according to an embodiment of this application is as follows:

[0039] The cylinder 102 drives the fixed roller 103 and the rotating roller 104 to press down. The rotating roller 104 drives the sliding column 3 to press down in the sliding groove 1030. The motor 100 drives the rubber roller 101 to rotate. The rolling part 2 is between the rubber roller 101 and the rotating roller 104. The rotating roller 104 rotates with the rolling part 2 during the rolling process. The rotation of the rotating roller 104 causes the circular groove 1040 to rotate around the slider 4. The rotating roller 104 is positioned on the fixed roller 103 by locking the slider 4 and the sliding column 3 through the threaded column 5. This avoids the situation where the slider 4 and the threaded column 5 are placed directly on the fixed roller 103 without the sliding column 3, the slider 4 and the threaded column 5, causing the roller to deviate.

[0040] During the process of the two-roller rolling machine 1 rolling the rolled part 2, the displacement mechanism is as shown in the attached diagram of the instruction manual. Figure 1 The state shown indicates that the displacement mechanism is in a stationary state.

[0041] After the winding of the coiled part 2 is completed, the operator controls the sliding end of the linear module 6 to slide horizontally, and simultaneously controls the synchronous dual-axis motor 8 to rotate, causing the winding wheel 9 to rotate synchronously so that the thick steel wire rope 10 can be unloaded. The operator then inserts the falling "C"-shaped part 14 into both ends of the coiled part 2 and tightens the screws 15 in sequence, so that the outer and inner walls of the coiled part 2 contact the pressure plate 16 and the bottom and top surface of the "C"-shaped part 14. This state is shown in the attached diagram of the instruction manual. Figure 2 The state shown is the wire laying state of the displacement mechanism;

[0042] Finally, the controller slides out the sliding end of the linear module 6, causing the rolled piece 2 to move out of the rotating roller 104. Once it has completely moved out of the rotating roller 104, the linear module 6 stops working, and the synchronous dual-axis motor 8 is controlled to release the wire so that the rolled piece 2 falls onto the trolley. This is an attached diagram from the instruction manual. Figure 3 The diagram shown is a structural schematic of the displacement mechanism in its placement state.

[0043] By operating the displacement mechanism, the laborious task of manually handling the rolled-up parts 2 can be avoided, while also accelerating the handling efficiency.

[0044] 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.
