Abstract
Description
Technical Field
[0001] The utility model relates to the field of sealing structures, in particular to a sealing ring and a medicinal material grinder with the sealing ring. Background Art
[0002] Sealing rings are a commonly used structure in mechanical equipment. They are used to separate two spaces within the equipment to avoid mutual interference. For example, in a grinder, a sealing ring is needed to block dust and prevent dust from entering the fine structure of the equipment and affecting the normal operation of the equipment.
[0003] Currently, the most common sealing rings are made of rubber, but rubber sealing rings have the disadvantages of being easily worn and aged. Therefore, some manufacturers also use metal materials to make sealing rings. The metal sealing rings installed at some shaft positions need to be set as a split structure because they need to cooperate with the rotation of the shaft. They usually include an inner ring and an outer ring. The inner ring can rotate relative to the outer ring. The inner ring is installed on the shaft and the outer ring is installed on the body. At this time, if the gap between the inner ring and the outer ring is too small, it will hinder the relative rotation of the inner ring and the outer ring. If the gap between the inner ring and the outer ring is too large, it cannot block dust well and affect the sealing effect. Therefore, a metal sealing ring with good sealing effect and no effect on the rotation of the inner ring relative to the outer ring is needed. Utility Model Content
[0004] The utility model aims to provide a sealing ring, which has the advantages of good sealing effect and does not affect the rotation of the inner ring relative to the outer ring.
[0005] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides the following technical solutions: a sealing ring, comprising an inner ring and an outer ring;
[0006] Also includes:
[0007] An inner sealing ring group and an outer sealing ring group, wherein the inner sealing ring group includes a plurality of sealing rings installed on an inner ring, and the outer sealing ring group includes a plurality of sealing rings installed on an outer ring, the sealing rings of the inner sealing ring group and the sealing rings of the outer sealing ring group are interspersed, and a gap is formed between the inner sealing ring group and the outer sealing ring group.
[0008] With the above technical solution, the inner ring is installed on the rotating shaft and the outer ring is installed on the body during use. When the equipment is running, the inner ring will rotate relative to the outer ring. During the rotation, dust entering the gap formed between the inner sealing ring group and the outer sealing ring group will be thrown toward the outer ring under the action of centrifugal force instead of moving toward the inner ring. The gap formed between the inner sealing ring group and the outer sealing ring group is formed by multiple bends between the inner ring and the outer ring. Dust cannot pass through the gap between the inner sealing ring group and the outer sealing ring group to achieve a good sealing effect. At the same time, since there is no contact between the inner ring and the outer ring, and between the inner sealing ring group and the outer sealing ring group, the inner ring can rotate smoothly relative to the outer ring, thereby achieving a good sealing effect without affecting the rotation of the inner ring relative to the outer ring.
[0009] In one embodiment of the utility model, the inner sealing ring group includes a first inner sealing ring, a second inner sealing ring and a third inner sealing ring; an inner limit ring is provided on the circumferential protrusion of the inner ring, a limit groove is provided on the circumferential edge of the inner ring, an intermediate clamping ring is installed in the limit groove, the first inner sealing ring and the second inner sealing ring are arranged between the intermediate clamping ring and the inner limit ring, and the first inner sealing ring and the second inner sealing ring are separated by a first separating ring; the third inner sealing ring is fixed to the inner ring, and the third inner sealing ring and the intermediate clamping ring are separated by a second separating ring.
[0010] Through the above technical scheme, during installation, the first inner sealing ring is first installed on the inner ring so that the first inner sealing ring is against the inner limiting ring, and then the first separating ring and the second inner sealing ring are placed in sequence, and then the middle clamping ring is inserted into the limiting groove, and the first inner sealing ring and the second inner sealing ring are fixed on the inner ring, and then the second separating ring is installed and the third inner sealing ring is fixed on the inner ring to complete the installation.
[0011] In one embodiment of the utility model, the outer sealing ring group includes a first outer sealing ring, a second outer sealing ring and a third outer sealing ring; an outer limiting ring is provided on the circumferential protrusion of the outer ring, the first outer sealing ring is abutted against the outer limiting ring, a third separating ring is provided on the side of the first outer sealing ring away from the outer limiting ring, the second outer sealing ring is abutted against the third separating ring; a locking ring is threadedly connected on the outer ring, the locking ring and the outer limiting ring squeeze and fix the first outer sealing ring, the second outer sealing ring and the third separating ring, and the third outer sealing ring is fixed to the locking ring; the second outer sealing ring is located between the first inner sealing ring and the second inner sealing ring, and the third outer sealing ring is located between the second inner sealing ring and the third inner sealing ring.
[0012] Through the above technical solution, during installation, the first outer sealing ring, the third separating ring and the second outer seal are installed on the outer ring in sequence, so that the first outer sealing ring is abutted against the outer limit ring, and then the locking ring is screwed into the outer ring to complete the assembly of the outer ring. When the inner ring and the outer ring are installed as a whole, the second outer sealing ring needs to be located between the first inner sealing ring and the second inner sealing ring, and the third outer sealing ring needs to be located between the second inner sealing ring and the third inner sealing ring.
[0013] The utility model also provides a medicinal material grinder, providing the following technical solution: including the above-mentioned sealing ring, and also including:

[0015] A grinding plate is installed on the shell, and grinding teeth are arranged on the grinding plate. A grinding rod for cooperating with the grinding teeth to grind medicinal materials is installed on the rotating shaft.
[0016] Through the above technical solution, when in use, the medicinal materials to be ground are placed in the shell, and then the door cover is closed. The external driving device drives the rotating shaft to rotate, and then drives the grinding rod to rotate, so that the grinding rod and the grinding teeth are relatively displaced to grind the medicinal materials. In this process, the sealing ring can prevent the dust generated by grinding from passing through the connection between the rotating shaft and the shell, thereby isolating the impact of grinding on other components; after the medicinal materials are ground to be small enough, they will be discharged from the discharge port through the filter.
[0017] In one embodiment of the present invention, a feed pipe is connected to the door cover, and a storage box is installed at one end of the feed pipe away from the door cover.
[0018] Through the above technical solution, the medicinal materials to be ground are placed in the storage box, and then gradually pushed into the feed pipe. The medicinal materials enter the shell through the feed pipe for grinding. The storage box can avoid frequent opening and closing of the door cover and is convenient to use.
[0019] In one embodiment of the present invention, a plurality of grinding rods are disposed around the axis of the rotating shaft.
[0020] Through the above technical solution, during one rotation of the shaft, the medicinal materials will come into contact with multiple grinding rods, thereby being ground multiple times, thereby increasing the number of grinding times and improving processing efficiency in the same amount of time.
[0021] As described above, the sealing ring of the utility model and the medicinal material grinder with the sealing ring have the following beneficial effects:
[0022] With the above technical solution, when in use, the inner ring is installed on the rotating shaft and the outer ring is installed on the machine body. When the equipment is running, the inner ring will rotate relative to the outer ring. During the rotation, the dust entering the gap formed between the inner sealing ring group and the outer sealing ring group will be thrown to the outer ring under the action of centrifugal force instead of moving toward the inner ring. The gap formed between the inner sealing ring group and the outer sealing ring group is formed by multiple bends between the inner ring and the outer ring. The dust cannot pass through the gap between the inner sealing ring group and the outer sealing ring group to achieve a good sealing effect. At the same time, since there is no contact between the inner ring and the outer ring, and between the inner sealing ring group and the outer sealing ring group, the inner ring can rotate smoothly relative to the outer ring, thereby achieving a good sealing effect without affecting the rotation of the inner ring relative to the outer ring.
[0023] When in use, put the medicinal materials to be ground into the shell, then close the door cover, and the external drive device drives the rotating shaft to rotate, and then drives the grinding rod to rotate, so that the grinding rod and the grinding teeth are relatively displaced to grind the medicinal materials. In this process, the sealing ring can prevent the dust generated by grinding from passing through the connection between the rotating shaft and the shell, thereby isolating the impact of grinding on other parts; after the medicinal materials are ground small enough, they will be discharged from the discharge port through the filter.
