Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0041] like Figures 2-4 As shown, this utility model discloses a support structure for reducing wear on the dustproof belt of an SD5 shredder. It includes a mounting block 5 fixedly installed outside the channel 31 of the frame 3. A support roller 6 is rotatably mounted on the mounting block 5, with its axis parallel to the length direction of the channel 31. The support roller 6 supports the dustproof belt 2. During operation, the support roller 6 and the dustproof belt 2 experience rolling friction. Compared to the sliding friction of existing technologies, rolling friction effectively reduces the coefficient of friction and extends the service life of both the support roller 6 and the dustproof belt 2.

[0042] In this embodiment, a first mounting ear 51 is fixedly provided at one end of the mounting block 5, and a second mounting ear 52 is detachably connected to the other end. Both the first mounting ear 51 and the second mounting ear 52 have shaft holes 53. Bearings 61 are installed at both ends of the support roller 6, and the bearings 61 are installed within the shaft holes 53. The support roller 6 can be removed by disassembling the second mounting ear 52. In other embodiments, both the first mounting ear 51 and the second mounting ear 52 can be directly fixedly connected to the mounting block 5.

[0043] In this embodiment, a hinge seat 54 is provided on the mounting block 5, and the second mounting ear 52 is rotatably connected to the hinge seat 54, so that the second mounting ear 52 is rotatably connected to the mounting block 5. An arc-shaped slot 521 is provided on the second mounting ear 52, the center of which is located on the rotation axis of the second mounting ear 52. The width of the arc-shaped slot 521 is the same as the diameter of the shaft hole 53, and the arc-shaped slot 521 communicates with the shaft hole 53. The support roller 6 enters and exits the shaft hole 53 through the arc-shaped slot 521. A locking member is provided on the second mounting ear 52 to seal the arc-shaped slot 521 and lock the relative position between the second mounting ear 52 and the mounting block 5. After the locking member is operated to release the locking of the second mounting ear 52 and the sealing of the arc-shaped slot 521, the support roller 6 can be removed from the mounting block 5 by rotating the second mounting ear 52, without completely removing the second mounting ear 52, effectively simplifying the disassembly and assembly process. In some other embodiments, the second mounting ear 52 may be detachably connected to the mounting block 5 by means of fixing bolts.

[0044] In this embodiment, the arc-shaped slot 521 opens downwards. Since the dustproof belt 2 applies upward pressure to the support roller, the downward opening of the arc-shaped slot 521 effectively reduces the wear of the support roller 6 on the locking member. In some other embodiments, the arc-shaped slot 521 may also open upwards.

[0045] In this embodiment, the locking element includes a fixing pin 7, a first fixing hole 522 on the second mounting ear 52 communicating with the arc-shaped groove 521, and a second fixing hole 55 on the mounting block 5. The fixing pin 7 passes through the first fixing hole 522 and is inserted into the second fixing hole 55. This achieves the sealing of the arc-shaped groove 521 and the locking of the relative position between the second mounting ear 52 and the mounting block 5. In other embodiments, the locking element may also be a fixing block or a fixing strip.

[0046] In this embodiment, a threaded hole is provided in the second fixing hole 55, and a threaded post is provided at the end of the fixing pin 7. The threaded post is threaded into the threaded hole, which can prevent the fixing pin 7 from moving at will. In this embodiment, a rotating cap 71 is provided at the end of the fixing pin 7 away from the threaded post, so as to facilitate the rotation of the fixing pin 7.

[0047] When the support structure of this utility model is working, the support roller 6 and the dustproof belt 2 are subjected to rolling friction. Compared with the sliding friction of the prior art, rolling friction can effectively reduce the coefficient of friction and extend the service life of the support roller 6 and the dustproof belt 2.

[0048] When disassembling the support roller of the support structure of this utility model:

[0049] First, rotate the rotating cap 71 to unscrew the threaded post of the fixing pin 7 out of the threaded hole.

[0050] Subsequently, the fixing pin 7 is taken out from the second fixing hole 55 and the first fixing hole 522.

[0051] Then, the second mounting lug 52 is rotated counterclockwise, and the supporting roller 6 is separated from the shaft hole 53 on the second mounting lug 52 from the arc-shaped notch 521.

[0052] Finally, the other end of the supporting roller 6 is taken out from the shaft hole 53 of the first mounting lug 51.

[0053] The above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, and all should be covered in the scope of the claims of the present application. The technical, shape and structure parts not described in detail in the present application are well-known technologies.
