There are many ways to grind glutinous rice into paste, such as traditional stone mill processing and modern electric grinders. However, neither method can achieve multi-stage grinding in a single process, resulting in some rice grains not being fully ground into paste and requiring further secondary processing. Therefore, it is necessary to provide a new glutinous rice grinding device to solve the above-mentioned technical problems. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0022] Please see Figures 1 to 5 The present invention provides a glutinous rice grinding device, which includes a hollow grinding cover 1, a grinding disc 2, a grinding plate 3, and an adjustment component 4.
[0023] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 5A grinding disc 2 is rotatably connected to and coaxially arranged within the hollow grinding cover 1. A rotary motor 5 for driving the grinding disc 2 to rotate is fixedly installed on the back of the hollow grinding cover 1. The gap between the grinding disc 2 and the inner wall of the hollow grinding cover 1 forms an annular grinding cavity 1-2. Multiple annularly distributed side sliding cavities 2a are opened on the grinding disc 2, and a grinding plate 3 is elastically connected inserted into each side sliding cavity 2a. A feed valve 12 and a discharge valve 13 are respectively installed on the upper and lower surfaces of the hollow grinding cover 1. A support frame 11 is also installed on the hollow grinding cover 1, which supports the hollow grinding cover 1, thus forming a vertical structure.
[0024] It should be noted that: glutinous rice is fed into the annular grinding chamber 1-2 through the feed valve 12, and the rotating motor 5 is turned on to drive the grinding disc 2 to rotate, so that the grinding plate 3 on the grinding disc 2 can grind the glutinous rice in the annular grinding chamber 1-2.
[0025] In the embodiments of this utility model, please refer to Figure 2 , Figure 3 and Figure 4 The grinding disc 2 has a side sliding cavity 2a in which multiple sliding rods 21 are fixedly installed along the radial direction of the grinding disc 2. The sliding rods 21 are inserted into the sliding holes in the grinding plate 3 and are slidably connected to the sliding holes. Each sliding rod 21 is fitted with a spring 22. One end of the spring 22 is fixedly connected to the insertion end of the grinding plate 3, and the other end of the spring 22 is fixedly connected to the inner wall of the side sliding cavity 2a. One end of the grinding plate 3 extends into the annular grinding cavity 1-2 and is fixedly provided with an integrally formed grinding protrusion 31.
[0026] The grinding disc 2 is also equipped with an adjustment component 4 for adjusting the distance between the grinding protrusion 31 and the inner wall of the hollow grinding cover 1. The adjustment component 4 includes an inner gear ring 41, which is rotatably mounted on the grinding disc 2. Multiple annularly distributed curved abutment plates 42 are mounted on the inner gear ring 41, and the curved abutment plates 42 abut against the abutment arc plates 32 fixedly mounted on the corresponding grinding plates 3. The adjustment component 4 also includes a drive gear 43, which is rotatably mounted on the grinding disc 2 and meshes with the inner gear ring 41. The grinding disc 2 is embedded with a servo motor for driving the drive gear 43 to rotate.
[0027] It is worth noting that: This implementation method is illustrated in the appendix. Figure 3 For example, its grinding disc 2 rotates counterclockwise for grinding.
[0028] It should be noted that: during grinding, the servo motor is turned on to drive the active gear 43 to rotate counterclockwise. Since the active gear 43 is meshed with the internal gear ring 41, it drives the curved abutment plate 42 on the internal gear ring 41 to deflect. Therefore, the curved abutment plate 42 causes the grinding plate 3 to slide a small section outward along the side sliding cavity 2a through the abutting arc plate 32. As a result, the distance between the grinding protrusion 31 and the inner ring wall of the hollow grinding cover 1 is reduced. At this time, when the grinding protrusion 31 rotates to the bottom of the annular grinding cavity 1-2, it can grind the glutinous rice that has fallen to the bottom of the annular grinding cavity 1-2. Then, the adjustment component 4 is used to further reduce the distance between the grinding protrusion 31 and the inner ring wall of the hollow grinding cover 1, thereby further grinding the glutinous rice paste.
[0029] This application allows for multiple grinding processes of glutinous rice at different degrees, resulting in a gradual process from coarse to fine grinding of the glutinous rice into a paste and then into powder, thereby improving the fineness of the glutinous rice paste.
[0030] The sliding rod 21 improves the stability of the grinding plate 3 when it slides in the side sliding cavity 2a, while the spring 22 can pull back the outwardly sliding grinding plate 3 when the servo motor reverses.
[0031] The working principle of the glutinous rice grinding device provided by this utility model is as follows:
[0032] Glutinous rice is fed into the annular grinding chamber 1-2 through the feed valve 12. The rotating motor 5 is turned on to drive the grinding disc 2 to rotate, so that the grinding plate 3 on the grinding disc 2 grinds the glutinous rice in the annular grinding chamber 1-2. During grinding, the servo motor is turned on to drive the drive gear 43 to rotate counterclockwise. Since the drive gear 43 is meshed with the inner gear ring 41, it drives the curved abutment plate 42 on the inner gear ring 41 to deflect. Therefore, the curved abutment plate 42 causes the grinding plate 3 to slide a small section outward along the side sliding cavity 2a through the abutment arc plate 32, thus reducing the distance between the grinding protrusion 31 and the inner ring wall of the hollow grinding cover 1. At this time, when the grinding protrusion 31 rotates to the bottom of the annular grinding chamber 1-2, it can grind the glutinous rice that has fallen to the bottom of the annular grinding chamber 1-2. Then, the adjustment component 4 is used to further reduce the distance between the grinding protrusion 31 and the inner ring wall of the hollow grinding cover 1, thereby further grinding the glutinous rice paste.
[0033] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
