The above are all prior arts, and this application does not protect them here, so no further elaboration is made.

[0025] The wear-resistant layers 2 are installed on the outer wall of the roller body 1 through a splicing mechanism, and the splicing mechanism includes a guide plug plate 10 installed at the bottom end of the upper wear-resistant layer 2, and the guide plug plates 10 are all inserted into the limiting grooves 11 opened on the outer wall of the lower wear-resistant layer 2. The outer wall of the guide plug plate 10 is plugged with a plug plate 9, and the plug plate 9 is installed on the side plate 8. The inner wall of the side plate 8 is installed with a movable inner rod 5, and the movable inner rod 5 is all movable in the side slot 3 under the action of the elastic potential energy of the first elastic member 4. The slots 3 are symmetrically arranged on the side wall of the lower wear-resistant layer 2; the side plate 8 is pulled outward under the action of the elastic potential energy of the first elastic member 4, and the plug-in plate 9 is driven to move outward to the maximum limit value. At this time, the guide plug-in plate 10 is inserted into the limit groove 11. After the bottom end of the guide plug-in plate 10 is inserted into the bottom end of the limit groove 11, the side plate 8 is sent away, so that under the action of the elastic potential energy of the first elastic member 4, the splicing and installation of the two sets of wear-resistant layers 2 on the outer wall of the roller body 1 are completed.

[0026] It should be noted that the arc center of each group of wear-resistant layers 2 is at the same position as the center of the roller body 1, and the inner wall of the wear-resistant layer 2 can be completely attached to the outer wall of the roller body 1 to provide wear-resistant protection for the outer wall of the roller body 1; at the same time, Figure 3 As shown, in this embodiment, a spring is used to force the movable inner rod 5 to move inside the side slot 3 as an elastic component, but in some other embodiments, other elastic components such as a reed, an elastic paddle, etc. may also be used.

[0027] like Figure 3 As shown, the inner walls of the side slots 3 are symmetrically provided with first slide rails 7, and the first slide rails 7 are slidably connected with first sliders 6, and the first sliders 6 are installed on the movable inner rod 5; with the coordinated use of the sliding action of the first slider 6 and the first slide rails 7, the stability of the movable inner rod 5 moving in coordination with the elastic potential energy of the first elastic member 4 is guaranteed.

[0028] like Figure 2 and Figure 3As shown, the guide plug plate 10 and the side plate 8 both adopt an arc shape that fits the outer wall of the wear-resistant layer 2; under the design of fitting the shape of the outer wall of the wear-resistant layer 2, the aesthetics of the forming device during use is guaranteed.

[0029] like Figure 3 and Figure 4 As shown, the inner wall of the guide plug plate 10 is equidistantly provided with a team inner side 12, and the inner wall of the inner side 12 is connected to a mounting frame 16 through a second elastic member 13, and a ball 17 abutting against the outer wall of the wear-resistant layer 2 is rollingly embedded in the inner wall of the mounting frame 16, and a second slide rail 14 is symmetrically arranged on the inner wall of the inner side 12, and a second slider 15 is slidably connected in the second slide rail 14, and the second slider 15 is installed on the mounting frame 16; when the guide plug plate 10 is inserted into the limiting groove 11, the rolling action of the ball 17 cooperates with the elastic potential energy of the second elastic member 13, so that the ball 17 is extended and retracted in the inner side 12 to drive the guide plug plate 10 to be inserted into the limiting groove 11, and the outer wall of the ball 17 can completely abut against the inner wall of the limiting groove 11, thereby promoting the smooth movement efficiency of the guide plug plate 10.

[0030] It should be noted that if Figure 4 In the embodiment shown, a spring is used to force the mounting frame 16 to move inside the inner side 12 , but in some other embodiments, other elastic components such as a reed, an elastic paddle, etc. may also be used.
