[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a small profile rolling machine, comprising: a base plate 1, with support plates 2 fixedly installed on both the left and right sides of the upper end of the base plate 1, and two rotating rollers 21 rotatably connected between the two support plates 2 via a rotating shaft 22. The center of the two rotating rollers 21 is at the same inclination angle as the base plate 1. An inclined groove 3 is opened on the lower side of one end of each of the two support plates 2. A moving block 5 is slidably connected in each groove 3 via a driving component. An adjusting roller 16 is rotatably connected between the two moving blocks 5. The adjusting roller 16 is located on the outer side between the two rotating rollers 21. The driving component can determine that the moving block 5 slides in the groove 3. When the moving block 5 slides, it moves the adjusting roller 16 synchronously, thereby adjusting the distance between the rotating rollers 21 and the adjusting roller 16, so that the profile can be rolled into rings of different diameters.

[0023] The driving component includes a steering box 19 fixedly installed at the bottom of the slide 3. The drive shafts between the two steering boxes 19 are connected by a rotating rod. A handle 18 is fixedly installed on the drive shaft of one of the steering boxes 19. By rotating the handle 18, the drive shafts of both steering boxes 19 can be driven to rotate simultaneously. A threaded rod 20 is fixedly installed on the other drive shaft of each steering box 19. When the handle 18 is rotated, the threaded rod 20 can be driven to rotate. A threaded cylinder 6 is connected to the outer end of each threaded rod 20. The threaded cylinder 6 is rotatably connected to the lower end of the moving block 5. When the threaded rod 20 rotates, it drives the threaded cylinder 6, thereby driving the moving block 5 to move within the slide 3, which facilitates the driving of the moving block 5.

[0024] An adjusting roller 16 is provided between the two movable blocks 5. Both ends of the adjusting roller 16 are provided with connecting grooves 17. The connecting grooves 17 are equilateral hexagonal in shape, and the size of the connecting grooves 17 is slightly larger than the size of the hexagonal cylinder 15. Each movable block 5 is rotatably connected to a connecting cylinder 8 through a bearing 12. The bottom end of the connecting cylinder 8 is provided with a limit groove 9. The inner end of the movable block 5 is provided with a circular groove. The outer wall of the bearing 12 is fixed in the circular groove. The outer wall of the connecting cylinder 8 is fixedly sleeved on the inner wall of the bearing 12. The connecting cylinder 8 can rotate within the movable block 5.

[0025] Each connecting groove 17 has a hexagonal cylinder 15 slidably inserted into it. The outer end of the hexagonal cylinder 15 is elastically connected to a round rod 10. A spring 14 is fixedly installed at one end of the round rod 10. One end of the round rod 10 is slidably inserted into the hexagonal cylinder 15, and the outer end of the spring 14 is fixedly connected to the inner side wall of the hexagonal cylinder 15. The round rod 10 can slide in the hexagonal cylinder 15 by compressing the spring 14. When the round rod 10 is inserted into the connecting cylinder 8, the adjusting roller 16 is rotatably installed between the two moving blocks 5, which facilitates the disassembly and assembly of the adjusting roller 16.

[0026] Specifically, first insert one end of the hexagonal cylinder 15 into the connecting groove 17, and push the round rod 10 inward. The round rod 10 slides into the hexagonal cylinder 15 through the compression spring 14. Then, align the other end of the round rod 10 with the outer port of the connecting cylinder 8. After releasing the hand, the outer end of the round rod 10 is pushed into the connecting cylinder 8 under the reaction force of the spring 14. Rotate the adjusting roller 16 between the two moving blocks 5. Then, according to the thickness of the profile to be rolled, adjust the distance between the rotating roller 21 and the adjusting roller 16 through the driving component. Rotate the rotating roller 21 to insert one end of the profile between the adjusting roller 16 and one rotating roller 21, and then rotate it out between the adjusting roller 16 and another rotating roller 21 to roll the profile.

[0027] Please see Figure 1 and Figure 2 In some embodiments, rotating shafts 22 are fixedly installed on both the left and right sides of the two rotating rollers 21. The rotating shafts 22 are rotatably connected to the support plate 2. One end of the two rotating shafts 22 passes through one of the support plates 2 and is fixedly installed with a sprocket 23. Chains 25 are driven to the outer walls of the two sprockets 23. A motor 25 is fixedly installed on the outer wall of the other support plate 2. The output end of the motor 25 is fixedly connected to one end of one of the rotating shafts 22. More specifically, the motor 25 drives one of the rotating shafts 22 to rotate. When the rotating shaft 22 rotates, it drives the rotating rollers 21 and the sprockets 23 to rotate. Under the action of the chain 25, both rotating rollers 21 are driven to rotate simultaneously.

[0028] Please see Figure 3 and Figure 4In some embodiments, limiting plates 4 are fixedly installed on the upper and lower sides of the inner end of each slide groove 3. The limiting plates 4 are L-shaped. When one end of the limiting plate 4 is fixed to the inner port of the slide groove 3, the other end is located on the outer side of the slide groove 3. A bearing 12 is fixedly sleeved on the outer wall of the round rod 10. A round plate 13 is fixedly installed on the outer wall of the bearing 12. When the moving block 5 slides to the inner side of the upper end of the slide groove 3, the round plate 13 is located at the rear end of the limiting plate 4 through the tension spring 14. More specifically, a guide slope is provided on the outer side of one end of the round plate 13, and a guide slope is provided at the lower end of the limiting plate 4. When the driving component drives the moving block 5 to move towards the inner end of the slide groove 3, the guide slope on the round plate 13 and the guide slope at the lower end of the limiting plate 4 contact each other, thereby pushing the round plate 13 outward and preventing the round rod 10 from sliding out of the connecting cylinder 8.

[0029] Working principle:

[0030] Step 1: First, insert one end of the hexagonal cylinder 15 into the connecting groove 17. Push the round rod 10 inward, and the round rod 10 will slide into the hexagonal cylinder 15 through the compression spring 14. Then, align the other end of the round rod 10 with the outer port of the connecting cylinder 8. After releasing your hand, under the reaction force of the spring 14, push the outer end of the round rod 10 into the connecting cylinder 8. Rotate the adjusting roller 16 between the two moving blocks 5.

[0031] Step 2: Then, depending on the thickness of the profile to be rolled, adjust the distance between the rotating roller 21 and the adjusting roller 16 by driving the component, rotate the rotating roller 21, insert one end of the profile between the adjusting roller 16 and one rotating roller 21, and then turn it out between the adjusting roller 16 and another rotating roller 21 to roll the profile.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
