Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-3 The utility model provides a rolling mill suitable for different diameters, including a bottom plate 1, vertical plates 2 are symmetrically installed on both sides of the surface of the bottom plate 1, and the inner walls of the two vertical plates 2 are plugged with adjustment structures 3. The central axis of the first roller 4 is rotatably installed between the two adjustment structures 3. A through groove is penetrated through the inner wall of the vertical plate 2, and the central axis of the first roller 4 penetrates the through groove. A motor 6 is fixedly installed on the side wall of the vertical plate 2 on one side, and the motor shaft of the motor 6 penetrates the vertical plate 2 on this side and is fixedly installed with a second roller 5. The central axis of the second roller 5 penetrates the vertical plate 2 on the other side, and the central axis of the second roller 5 is rotatably connected to the vertical plate 2 on this side, and the outer end of the central axis of the second roller 5 is connected to the central axis of the first roller 4 through a linkage structure 7.

[0015] A stable frame structure is formed by the bottom plate 1 and the two vertical plates 2, which is used to assemble various groups of components of the head rolling machine. The head of the pipe can be processed by setting two rollers. The distance between the two rollers can be adjusted according to the different specifications and sizes of pipes, ensuring a wide range of applications and strong practicality. The motor 6 provides power for the rollers, and the two rollers are adjusted to rotate simultaneously and in opposite directions through the linkage structure 7 on the other side to ensure the use effect of the rollers. The linkage component 7 can adapt to the displacement of the upper first roller 4 to ensure the applicability of the equipment. The first roller 4 can be adjusted to move stably through the adjustment structure 3.

[0016] The adjustment structure 3 includes a screw rod 31, which is screwed to the inner wall of the vertical plate 2. Two slide rails 34 are symmetrically provided on the inner wall of the vertical plate 2. The slide rails 34 are arranged at 90 degrees to the through groove. A support tube 33 is slidably connected between the two slide rails 34. The inner wall of the support tube 33 is rotatably assembled with the central axis of the first rolling roller 4. A rotating shaft 32 is fixedly assembled at the lower end of the screw rod 31, and the rotating shaft 32 is rotatably connected to the support tube 33.

[0017] When the adjustment structure 3 is needed, the screw rod 31 is first rotated. According to the screw connection between the screw rod 31 and the vertical plate 2, the displacement of the support tube 33 on the inner wall of the slide rail 34 can be adjusted. The support tube 33 is restricted by the slide rail 34 and will not rotate with the rotating shaft 32, so the center axis displacement of the first roller 4 can be stably driven.

[0018] The linkage structure 7 includes a first gear 71, which is connected to the central axis of the first roller 4. A through groove is provided on the outer wall of the vertical plate 2, and an electric push rod 74 is installed in the through groove. The piston rod side end of the electric push rod 74 is rotatably installed with a second gear 72, and the second gear 72 is slidably installed in the slide groove. The first gear 71 is meshed with the second gear 72. The central outer end of the second gear 72 is connected to the central axis of the second roller 5 through a transmission belt component 73. The side wall of the transmission belt component 73 is equipped with a tensioning structure 8, and the tensioning structure 8 is connected to the side wall of the vertical plate 2.

[0019] The tensioning structure 8 includes a support plate 81, which is fixedly assembled on the side wall of the vertical plate 2.

A roller 85 is rotatably assembled on the end of the inner wall of the support 84, and the roller 85 fits against the side wall of the transmission belt of the transmission belt component 73.

[0020] When the motor 6 drives the second roller 5 to rotate, it will also drive the transmission belt member 73 to rotate, and at the same time drive the second gear 72 to rotate. According to the meshing effect of the second gear 72 and the first gear 71, the first gear 71 rotates in the opposite direction, driving the first roller 4 to rotate in the opposite direction. When the adjustment structure 3 drives the first roller 4 to move, the first gear 71 moves accordingly, and controls the electric push rod 74 to retract, driving the second gear 72 to move, and always meshing with the first gear 71. At the same time, the belt tightness of the transmission belt structure 73 changes, and the adjustment stud 82 moves on the inner wall of the support plate 81, and drives the roller 85 to move through the support 84. The roller 85 tightens the belt of the transmission belt structure 73 to keep it in normal transmission operation. The limit rod 83 can limit the support 84 from rotating with the stud 82.
