[0018] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0019] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. The described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0020] Figure 1 , 2 It includes a telescopic cylinder 1, a fixed seat 11, a first fixed plate 12, a U-shaped groove 13, a connecting seat 2, a supporting arm 3, an adjusting rod 31, a fixing ring 32, a second fixed plate 33, a second pressure roller mounting seat 34, a first pressure roller mounting seat 4, a bearing seat 41, a pressure roller 5, a pressure plate 51, etc.

[0021] like Figure 1 ,2 As shown, the utility model is a pressing roller mechanism, comprising a telescopic cylinder 1, which can swing around its mounting portion.

[0022] The support and pressure arm assembly is arranged below the telescopic cylinder 1 and can be driven by the telescopic cylinder 1 to rotate around the rotating connection part at one end of the support and pressure arm assembly.

[0023] The two pressing rollers 5 are symmetrically rotatably arranged at the other end of the supporting pressing arm assembly. The outer diameters of the two pressing rollers 5 increase smoothly from one end close to each other toward the other end, so that the outer surfaces of the two pressing rollers 5 form a tire pressing station.

[0024] Furthermore, both sides of the head of the telescopic cylinder 1 are rotatably connected to a fixing seat 11, and each fixing seat 11 is respectively installed on the first fixing plate 12. Thus, the telescopic cylinder 1 is rotatably connected to the first fixing plate 12.

[0025] A U-shaped groove 13 is provided on the first fixing plate 12 corresponding to the space between the two fixing seats 11 , and the output shaft of the telescopic cylinder 1 extends downward through the U-shaped groove 13 , thereby driving the supporting and pressing arm assembly to rotate, thereby realizing the pressing operation of the pressing roller 5 .

[0026] The support and pressure arm assembly includes two support and pressure arms 3 arranged parallel to each other. One ends of the two support and pressure arms 3 are connected by an adjusting rod 31. Both ends of the adjusting rod 31 extend out of the corresponding support and pressure arms 3 and are respectively rotatably supported in a fixing ring 32. Each of the fixing rings 32 is respectively installed on a second fixing plate 33.

[0027] A first pressing roller mounting seat 4 is mounted on the other end of the two pressing supporting arms 3 , and a bottom surface of the first pressing roller mounting seat 4 is fixedly connected to a bearing seat 41 .

[0028] A through hole is formed at one end of the pressure roller 5 close to the bearing seat 41, and a screw is arranged in the through hole to fix the pressure roller 5 to the bearing seat 41, and a pressing plate 51 is sleeved on the screw inside the pressure roller 5. Thus, the pressure roller 5 is rotatably connected to the bearing seat 41, and the pressure roller 5 can rotate freely during operation and press the tire-like workpiece.

[0029] In order to ensure that the supporting and pressing arm 3 can drive the pressure roller 5 to reliably press the workpiece during operation, the supporting and pressing arm 3 is constructed to include a horizontal portion and a bent portion, an obtuse angle is formed between the horizontal portion and the bent portion, the lower end of the bent portion is connected to the first pressure roller mounting seat 4, and the outer end of the horizontal portion is connected to the adjusting rod 31.

[0030] The connecting seat 2 is fixedly connected to the second pressing roller mounting seat 34 , and the second pressing roller mounting seat 34 is fixedly connected to the two supporting pressing arms 3 .

[0031] like Figure 1 , 2As shown, the working process of the utility model is as follows: when the tire-shaped material enters under the mechanism, the telescopic cylinder 1 installed on the second fixed plate 12 performs the extension and pressure work, and the extension and pressure of the telescopic cylinder 1 drives the supporting and pressing arm 3 to rotate around the adjusting rod 31, forcing the pressure roller 5 to apply pressure downward, ensuring that the material can be continuously and accurately straightened. After the work is completed, the telescopic cylinder 1 performs the contraction and pressure work, and the supporting and pressing arm 3 rises to drive the pressure roller 5 to retract to its original initial state.

[0032] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
