[0023] As shown in the drawings, Figures 1-4 A waste support machine cutter roller tensioning device of the present application comprises a support 11, a swing arm 12, a tensioning wheel 13 and an adjusting assembly, the support 11 is fixedly installed on the waste support machine 1 through threaded connection, one end of the swing arm 12 is connected with the support 11, and the other end is rotatably connected with the tensioning wheel 13.

[0024] The adjusting assembly comprises a fixed rod 141 fixedly installed on the waste support machine 1, a rotating hanger ring screw 142 connected between the fixed rod 141 and the swing arm 12, and the rotating hanger ring screw 142 adjusts the length through rotating thread.

[0025] In the present embodiment, as shown in the drawings, Figure 2 The rotating hanger ring screw 142 comprises a hook 1421, a connecting frame 1422 and a hanger ring 1423 connected in sequence. The length of the rotating hanger ring screw 142 can be adjusted by rotating the thread, so as to provide different pulling forces for the swing arm 12, and the tensioning force is provided to the waste support machine cutter roller through the tensioning wheel 13.

[0026] In the present embodiment, as shown in the drawings, Figure 3 The support 11 is provided with a spring 111, specifically, one end of the spring 111 is fixedly connected with the support 11, the other end is fixedly connected with an adjusting block 112, the adjusting block 112 is in sliding fit with the support 11, and the two ends of the adjusting block 112 are provided with protrusions to limit the adjusting block 112.

[0027] In the embodiment, the support 11 is arranged to allow the swing arm 12 to float in a small range (e.g. Figure 4 The swing arm 12 is connected to the tension wheel 13, and when the transmission belt of the waste branch machine deviates, the elongated or compressed spring 111 provides a correcting thrust or pressure through the tension wheel 13, so as to realize the automatic deviation correction function of the tension device.

[0028] In the embodiment, the middle part of the swing arm 12 is provided with a through hole for connecting the hook 1421. When the hook 1421 is hung at different through hole positions, the direction of the force component changes, and by replacing the through hole position connected by the hook 1421, the length of the force arm can be changed, so that the rotating ring screw 142 can provide different tension curves.

[0029] In the embodiment, the height position of the ring 1423 is adjusted conveniently, and the ring 1423 can rotate relative to the fixed rod 141. The fixed rod 141 is provided with an external thread, and the ring 1423 is threadedly connected with the fixed rod 141. Meanwhile, the two sides of the ring 1423 are provided with fixed nuts for limiting the height position of the ring 1423.
