[0020] The utility model is further described below in combination with the drawings and implementation.

[0021] Please combine with reference to Figure 1 、 Figure 2 、 Figure 3 Among them Figure 1 A preferred embodiment structure diagram of the polishing roller of the polishing machine for rice processing is provided by the utility model; Figure 2 For Figure 1 The structure diagram of the right view of the polishing roller body part is shown. Figure 3 For Figure 2 The structure diagram of the left view of the support plate part is shown, and the polishing roller of the polishing machine for rice processing comprises a polishing roller body 1, and the left side of the polishing roller body 1 is provided with a cleaning structure 2.

[0022] The cleaning structure 2 comprises support plates 21 arranged at the left and right ends of the polishing roller body 1, and the top of the opposite side of the two support plates 21 is provided with sliding guide rods 22 in the transverse direction, and the peripheral side of the sliding guide rod 22 is provided with a cleaning ring 23 that can slide left and right along the length direction, and the cleaning ring 23 is slidably connected with the outside of the polishing roller body 1.

[0023] Through the arrangement of the cleaning ring 23, when the cleaning ring 23 moves left and right in the direction of the sliding guide rod 22, the dust on the peripheral side of the polishing roller body 1 in the cleaning ring 23 can be removed.

[0024] A group of size gears 24 are arranged at the left end of the polishing roller body 1, the left end of the polishing roller body 1 is fixedly connected with the pinion of the size gear 24, and the left side of the large gear of the size gear 24 is fixedly provided with a connecting rod 25.

[0025] The small gear drives the large gear, so as to realize speed reduction, so as to ensure that the rotating speed of the connecting rod 25 driven by the high-speed rotating polishing roller body 1 is reduced.

[0026] The left end of the connecting rod 25 and the left side of the left supporting plate 21 are rotatably provided with a connecting plate 26, the top of the left side of the left supporting plate 21 is rotatably provided with a first driving tooth 27, the inner side of the first driving tooth 27 is provided with a sliding groove, and the front end of the connecting plate 26 is slidably connected with the inner side of the sliding groove.

[0027] When the connecting rod 25 rotates, the connecting plate 26 is driven to rotate, and then the front end of the connecting plate 26 slides in the sliding groove, so that the connecting plate 26 drives the first driving tooth 27 to swing back and forth.

[0028] The bottom of the first driving tooth 27 is slidably provided with a rack 28 along the arc direction, and the bottom of the first driving tooth 27 and the left and right sides of the rack 28 are slidably provided with a positioning block 29.

[0029] The length of the rack 28 sliding on the first driving tooth 27 can be determined by the positioning block 29, and then the length of time when the rotating screw 4 is stopped each time is determined.

[0030] The bottom of the left side of the left supporting plate 21 is rotatably provided with a second driving tooth 3, the second driving tooth 3 and the bottom of the rack 28 are in meshing relationship, the opposite side of the two supporting plates 21 and below the polishing roller body 1 are provided with a rotating screw 4, the circumferential surface of the rotating screw 4 is threadedly connected with the inner side of the bottom of the cleaning ring 23, and the left end of the rotating screw 4 is fixedly connected with the right side of the second driving tooth 3.

[0031] When the first driving tooth 27 swings, the rack 28 slides on the bottom of the first driving tooth 27, when the rack 28 slides to one side limit, the rack 28 cannot slide and drives the second driving tooth 3 meshing with it to rotate, and then the rotation of the second driving tooth 3 drives the rotating screw 4 to rotate, and the rotation of the rotating screw 4 drives the cleaning ring 23 to slide on the circumferential surface of the polishing roller body 1, and when the first driving tooth 27 swings to the other side, the rack 28 is slid to the other side limit position again, so that the cleaning ring 23 can slide to the other side again, and the polishing roller body 1 can be repeatedly cleaned (the thread of the rotating screw 4 matches the number of times that the second driving tooth 3 is driven to rotate by the rack 28 once, that is, the number of turns of the second driving tooth 3 from the beginning to the end of the rotation on one side can just drive the cleaning ring 23 to move and slide through the circumferential surface of the polishing roller body 1).

[0032] The left side of the left supporting plate 21 is provided with a cover plate 5, and the cover plate 5 and the left supporting plate 21 are detachably arranged.

[0033] Part of the structure is closed by the cover plate 5, and since the structure is inside the cover plate 5, maintenance is facilitated.

[0034] The working principle of the polishing roller of the polishing machine for rice processing is as follows:

[0035] First step: when in use, the high-speed rotation of the polishing roller body 1 drives the size gear 24 to rotate, and then drives the connecting rod 25 to rotate, which drives the connecting plate 26 to rotate, and then the front end of the connecting plate 26 slides in the sliding groove, so that the connecting plate 26 drives the first drive tooth 27 to swing back and forth, and when the first drive tooth 27 swings, the rack 28 slides at the bottom thereof, and when the rack 28 slides to the limit on one side, the rack 28 cannot slide, thereby driving the second drive tooth 3 meshed therewith to rotate, and then the rotation of the second drive tooth 3 drives the rotating lead screw 4 to rotate;

[0036] Second step: the rotation of the rotating lead screw 4 drives the cleaning ring 23 to slide on the peripheral side surface of the polishing roller body 1, and when the first drive tooth 27 swings to the other side, the rack 28 is repeatedly slid to the limit position on the other side, so that the cleaning ring 23 is re-slid to the other side, and the polishing roller body 1 can be repeatedly cleaned (the thread of the rotating lead screw 4 is matched with the number of times that the rack 28 drives the second drive tooth 3 to rotate once, that is, the number of turns of the second drive tooth 3 from the beginning to the end of the rotation can just drive the cleaning ring 23 to move and slide through the peripheral side surface of the polishing roller body 1).

[0037] Compared with the related art, the polishing roller of the polishing machine for rice processing has the following beneficial effects:

[0038] Through the setting of the first drive tooth 27 capable of swinging back and forth, the second drive tooth 3 is driven to rotate forward and reverse, and then the cleaning ring 23 is driven to move left and right on the peripheral side surface of the polishing roller body 1, so that the cleaning ring 23 can clean the bran accumulated on the peripheral side surface of the polishing roller body 1, improve the polishing effect, and through the setting of the positioning block 29, the duration of the cleaning ring 23 staying on one side of the polishing roller body 1 is determined, so that the cleaning ring 23 can clean while not excessively affecting the polishing work, and the structure is simple and compact, and is not prone to failure, and through the setting of the cover plate 5, the maintenance is also relatively convenient.

[0039] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process conversion by using the contents of the utility model specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the utility model.
