Description

Technical Field

[0001] The utility model relates to the field of traditional Chinese medicine processing, in particular to a grinding device for producing traditional Chinese medicine slices. Background Art

[0002] In ancient times, the grinding of Chinese herbal medicine slices mainly relied on manual operations, using tools such as stone mills and mortars for grinding. Although this method can meet certain production needs, it is inefficient, and the particle size and uniformity of grinding are difficult to guarantee. At the same time, it is labor-intensive. For example, in small Chinese medicine workshops, pharmacists grind Chinese herbal medicine slices by manually turning stone mills, which is time-consuming and labor-intensive. With the advancement of industrial technology, mechanical grinding equipment has gradually been applied to the production of Chinese herbal medicine slices. These devices use motors to drive grinding parts, such as grinding wheels and grinding discs, to crush and grind Chinese herbal medicine slices. Compared with traditional manual grinding, mechanical grinding greatly improves production efficiency and can better control the particle size and uniformity of grinding. For example, common Chinese herbal medicine slice grinders use high-speed rotating blades or grinding wheels to cut and grind Chinese medicine;

[0003] In the prior art grinding device, the grinding gap is narrow, so the material is easily blocked in the grinding gap. The present invention solves the above problem. Utility Model Content

[0004] The utility model aims to solve the technical problem of the grinding device in the prior art that the grinding gap is narrow and the material is easily blocked in the grinding gap, thereby providing a grinding device for producing Chinese medicine slices.

[0005] A grinding device for producing Chinese herbal medicine slices includes: a grinding chamber, a feeding port is opened on the top wall of the grinding chamber, an input shaft is rotatably connected to the axis of the top wall of the grinding chamber, a cone block is connected to the lower end of the input shaft, a spiral blade is connected to the outer surface of the cone block, the diameter of the spiral blade is the same as the diameter of the grinding chamber, a grinding roller is connected to the lower end of the cone block, a gap is left between the grinding roller and the inner wall of the grinding chamber, a spiral grinding strip is connected to the outer wall of the grinding roller in the gap, and the spiral direction of the spiral grinding strip is consistent with that of the spiral blade.

[0006] Furthermore, the grinding roller includes a feeding section and a grinding section. The feeding section is in contact with the inner wall of the grinding chamber. A gap is left between the grinding section and the inner wall of the grinding chamber. A feeding port 2 is opened on the outer surface of the feeding section and extends to the grinding section. The horizontal cross-sectional area of ​​the feeding port 2 of the grinding section gradually decreases from top to bottom.

[0007] Beneficial effects of the utility model:

[0008] The crushed raw materials on the cone block are pressed into the grinding gap by the spiral blades. After entering the gap, the spiral grinding bars guide the raw materials to be discharged while assisting the grinding of the raw materials, thus achieving better grinding effect.

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] The rotational connection described in this device refers to the process of baking the bearing on the shaft, providing a spring retaining ring groove on the shaft or the shaft hole, and clamping the elastic retaining ring in the retaining ring groove to achieve axial fixation of the bearing and realize rotation; the articulation refers to a connection method that is achieved by performing activities on connecting parts such as hinges, pins and short shafts.

[0015] The present invention will be described in detail below with reference to the accompanying drawings. Example

[0016] The following is combined with Figure 1-3 The present embodiment describes a grinding device for producing Chinese herbal medicine slices, comprising: a grinding chamber 1, a feed port 2 being provided on the top wall of the grinding chamber 1, an input shaft 3 being rotatably connected to the top wall of the grinding chamber 1, a cone block 4 being connected to the lower end of the input shaft 3, a spiral blade 5 being connected to the outer surface of the cone block 4, the diameter of the spiral blade 5 being the same as the inner diameter of the grinding chamber 1, a grinding roller 6 being connected to the lower end of the cone block 4, a gap being left between the grinding roller 6 and the inner wall of the grinding chamber 1, a spiral grinding strip 7 being connected to the outer wall of the grinding roller 6 in the gap, the spiral direction of the spiral grinding strip 7 being consistent with that of the spiral blade 5;

[0017] The crushed raw materials are placed on the cone block 4 through the feed port 2, and the power of the input shaft 3 is turned on. The input shaft 3 drives the cone block 4, spiral blades 5, grinding rollers 6, and spiral grinding bars 7 to rotate. The spiral blades 5 press the raw materials along the inclined surface of the cone block 4 into the gap between the grinding roller 6 and the grinding chamber 1. The raw materials roll and rub in the gap for grinding. When the raw materials come into contact with the spiral grinding bars 7, the spiral grinding bars 7 drive the raw materials to move and roll at the same time, thereby enhancing the grinding effect and guiding the discharge of the ground raw materials to prevent blockage.

[0018] The grinding roller 6 includes a feeding section 61 and a grinding section 62. The feeding section 61 contacts the inner wall of the grinding chamber 1, and a gap is left between the grinding section 62 and the inner wall of the grinding chamber 1. A second feeding port 63 is formed on the outer surface of the feeding section 61 and extends to the grinding section 62. The horizontal cross-sectional area of ​​the second feeding port 63 of the grinding section 62 gradually decreases from top to bottom.

[0019] By feeding through the second feed port 63 on the grinding section 62, large-sized raw materials can enter the grinding gap more easily. The horizontal cross-sectional area of ​​the second feed port 63 of the grinding section 62 gradually decreases from top to bottom, which facilitates the discharge of raw materials in the second feed port 63 of the grinding section 62 and prevents blockage caused by siltation.

[0020] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.

[0021] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
