Through adopting above-mentioned technical scheme, the setting of parting bead divides into polylith transition region with the passageway that passes through, makes the material difficult piling up at the in-process that passes through to keeping away from the feed inlet milling strip by the milling strip that is close to the feed inlet to the uniformity degree of powder has further been improved.

Optionally, two sides of the dividing strip in the width direction are arranged in a bending manner towards the central axis of the dividing strip.

By adopting the technical scheme, when the division bars are cleaned, residues convenient to clean can be washed down along the bent parts of the division bars, so that the grinding disc is convenient to clean.

In summary, the present application includes at least one of the following beneficial technical effects:

1. the pitch difference between the grinding teeth on different grinding strips is convenient for gradually grinding the materials, so that the uniformity of the powder is improved;

2. the grinding strips are coaxially and annularly arranged, and the grinding strips and the feeding holes are coaxially arranged, so that the possibility that materials are fully ground in all directions is improved, and the uniformity of powder is further improved;

3. when two mill relatively rotate and polish the material, the distance between the abrasive bars of keeping away from the feed port is littleer than the distance between the abrasive bars that is close to the feed port, therefore is more careful after the abrasive bars of keeping away from the feed port are polished.

Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses mill for plastic particle pulverizer. Referring to fig. 1, the grinding disc for the plastic particle grinding machine comprises a disc body 1, wherein a fixing hole 2 and a feeding hole 3 are formed in the disc body 1, the fixing hole 2 is used for fixing the grinding disc on the grinding machine, and the feeding hole 3 is located in the center of the grinding disc and used for enabling materials to enter the grinding disc. A plurality of grinding strips 4 are fixedly mounted on the disc body 1, in this embodiment, the grinding strips 4 include a first rack 41 and a second rack 42, the first rack 41 is the grinding strip 4 close to the feed hole 3, and the second rack 42 is the grinding strip 4 far away from the discharge hole. The first rack 41 and the second rack 42 are coaxially arranged in an annular shape, and the grinding strip 4 and the feeding hole 3 are also coaxially arranged, so that the possibility that materials are fully ground in all directions is improved, and the uniformity of powder is improved.

Referring to fig. 1, grinding teeth 5 are fixedly mounted on a grinding bar 4, the tooth pitch on a first rack 41 is larger than that on a second rack 42, a transition channel 6 is formed between the first rack 41 and the second rack 42 at intervals, and the height of one end, close to a feed hole 3, of the transition channel 6 is higher than that of one end, far away from the feed hole 3, of the transition channel 6, so that materials are firstly ground into powder with larger particle size through the first rack 41, and then under the guidance of the transition channel 6, the materials are moved into the second rack 42 by virtue of centrifugal force generated when a grinding disc rotates and ground into powder with smaller particle size, so that the materials are conveniently ground from the powder with larger particle size to the powder with smaller particle size step by step, and the uniformity of the powder is further improved.

Referring to fig. 1, a plurality of separation strips 61 are sequentially and uniformly installed on the transition passage 6 at intervals, in this embodiment, there are six separation strips 61, and the length direction of the separation strips 61 is arranged along the radial direction of the tray body 1. The partition strip 61 uniformly divides the transition passage 6 into six transition areas, so that the materials are not easy to accumulate in the process of transition from the first rack 41 to the second rack 42, and the uniformity of the powder is further improved.

Referring to fig. 1, the thickness of the second rack 42 is greater than that of the first rack 41, and when the two grinding discs rotate relatively to grind the material, the powder of the material after grinding by the second rack 42 is finer. The width of the first rack 41 is greater than that of the second rack 42, so that the initial grinding space of the material is increased, and the sufficient degree of the material when being ground is improved.

Referring to fig. 1 and 2, the cross section of the grinding tooth 5 is triangular, and both sides of the grinding tooth 5 are bent toward the central axis of the grinding tooth 5, the cross section of the division bar 61 is hourglass-shaped, and both sides of the division bar 61 in the width direction are bent toward the central axis of the division bar 61. When cleaning the grinding disc, the cleaned residues can be washed down along the curved portions of the grinding teeth 5 and the separating strips 61, thereby facilitating the cleaning of the grinding disc.

The implementation principle of the grinding disc for the plastic particle grinding machine in the embodiment of the application is as follows: when the material is polished, the material is polished into powder with a larger particle size through the first rack 41, the material passes through the transition area, the uniformity of distribution of the material in the transition passage 6 is improved, and finally the material moves to the second rack 42 by virtue of the centrifugal force generated when the grinding disc rotates and is polished into powder with a smaller particle size.

Because the thickness of the second rack 42 is greater than that of the first rack 41, when the two grinding discs rotate relatively to grind the material, the powder of the material after grinding by the second rack 42 is more delicate. Since the width of the first rack 41 is greater than that of the second rack 42, the space where the material is initially ground is increased, thereby improving the degree of sufficiency when the material is ground.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
