Description

Technical Field

[0001] The utility model belongs to the technical field of dumbbells, and specifically relates to a grinding mechanism for toothpaste raw materials. Background Art

[0002] Toothpaste is a commonly used cleaning product in daily life and has a very long history. Toothpaste is usually composed of powdery abrasives, humectants, surfactants, adhesives, fragrances, sweeteners and other special components. Among them, the abrasives produced have relatively large particle sizes, a wide particle size range and uneven distribution, and it is necessary to grind them to homogenize the particle sizes.

[0003] Currently, it is usually ground by a grinding device. In the related technology, reference can be made to the Chinese utility model patent with the authorization publication number CN218282044U, which specifically discloses a grinding device for toothpaste raw materials, including a grinding barrel. A grinding seat is fixed at the bottom end inside the grinding barrel. A discharge groove is vertically drilled through the bottom end inside the grinding barrel. A second grinding block is inserted inside the grinding seat. The dimensional difference formed between the first grinding block and the grinding barrel from top to bottom can grind the raw materials from large to small.

[0004] The applicant found that the above design mainly performs grinding operations through the dimensional difference between the first grinding block and the grinding barrel. Since the feeding port is only provided on one side of the first grinding block, when the material is discharged into the grinding barrel, the material will only be ground by the grinding block part below the feeding port, resulting in uneven grinding at each position of the grinding block during grinding, increasing the wear degree of the corresponding grinding position of the grinding block, and thus affecting the grinding effect of the grinding block and the grinding device itself.

[0005] In view of this, a grinding mechanism for toothpaste raw materials is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a grinding mechanism for toothpaste raw materials in order to solve the above-mentioned problems.

[0007] The technical solution adopted by the utility model is as follows: A grinding mechanism for toothpaste raw materials includes a grinding box. An external grinding head is installed inside the lower side of the grinding box. An internal grinding head is arranged inside the external grinding head. A grinding channel is formed by surrounding between the internal grinding head and the external grinding head. A feeding port is opened on the grinding box directly above the internal grinding head. A flow equalizing table is arranged inside the grinding box directly below the feeding port. The bottom end surface of the flow equalizing table is located directly above the grinding channel. A driving component for driving the internal grinding head to rotate is provided at the bottom end of the flow equalizing table.

[0008] In a preferred embodiment, the driving assembly includes a driving motor, a planetary gearbox and a connecting rod. The driving motor is accommodated inside the bottom end of the flow equalizing table. The output end of the driving motor is fixedly connected to the input end of the planetary gearbox. The output end of the planetary gearbox is fixedly connected to the connecting rod. The housing part of the planetary gearbox is installed at the bottom end of the flow equalizing table.

[0009] In a preferred embodiment, the overall shape of the flow equalizing table is a conical shape with a narrower upper part and a wider lower part. Support rods fixed on the inner wall of the grinding box are provided at both ends of the flow equalizing table.

[0010] In a preferred embodiment, the external grinding head includes an external grinding body. Inside the external grinding body, a main blade and a fine blade are circumferentially provided from top to bottom. The main blade inclines from outside to inside, and the fine blade inclines from inside to outside.

A spiral groove and a circumferentially arranged second fine blade are provided at the outer end of the internal grinding body from top to bottom. The internal grinding body is installed together with the connecting rod.

[0012] In a preferred embodiment, a discharge port is detachably installed on the grinding box below the grinding channel. Support legs are installed at the four ends of the bottom of the grinding box.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, a flow equalizing table is provided directly above the grinding channel. When the material is poured along the feed port, the material will first come into contact with the flow equalizing table, and then flow along the inclined surface of the flow equalizing table to different positions of the grinding channel, which can ensure the grinding uniformity at each position as much as possible, and can ensure the overall service life while ensuring the grinding effect;
