Detailed Description

The utility model is described in further detail below with reference to the accompanying drawings.

The embodiments described by referring to the drawings are exemplary and intended for purposes of illustrating the present application and are not to be construed as limiting the present application. In the description of the present application, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," etc. indicate or are based on the orientation or positional relationship shown in the drawings, merely for convenience of description and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present application. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, the meaning of "a number", "a plurality" or "a plurality" is two or more, unless explicitly defined otherwise. In the present application, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be. In this application, unless expressly stated or limited otherwise, a first feature "above" or "below" a second feature may include both the first and second features being in direct contact, and may also include the first and second features not being in direct contact but being in contact with each other by way of additional features therebetween. Moreover, a first feature being "above," "over" and "on" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is higher in level than the second feature. The first feature being "under", "below" and "beneath" the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is less level than the second feature.

In view of the technical problems described in the background art, as shown in fig. 1-3, a semi-automatic knife sharpening device is provided, comprising: the machine shell comprises an upper shell and a lower shell arranged at the lower part of the upper shell, wherein more than one obliquely arranged knife sharpening groove is arranged on the end face of the upper shell; the knife sharpening device is arranged in the shell and comprises a motor, a transmission shaft connected with the motor and more than one knife sharpening wheel, wherein the knife sharpening wheel is arranged below the knife sharpening groove.

In view of the technical content described in the background art, when the semi-automatic knife sharpening device is used, two knife sharpening wheels are preferably adopted, one knife sharpening wheel is used for carrying out rough grinding on a knife, the other knife sharpening wheel is used for carrying out fine grinding on the knife, and the knife is ground by sections, so that the single knife sharpening wheel can be avoided to carry out knife sharpening, the service life is prolonged, the semi-automatic knife sharpening device is more suitable for practical use, and meanwhile, more than one knife sharpening groove is arranged on the upper shell, wherein on one hand, the number of the knife sharpening grooves is increased, and knife sharpening can be carried out on different positions of the knife sharpening grooves.

When the knife sharpening device is used, a knife to be sharpened is manually placed in the knife sharpening groove, and the knife sharpening operation is completed by manually moving the knife back and forth due to the fact that the motor drives the knife sharpening wheel to rotate. Wherein, because the sharpening groove is the slope setting, the sharpening groove spanes the sharpening wheel, and sharpening groove has different sharpening positions for sharpening wheel promptly, when long-term use, because the loss of sharpening wheel leads to some positions unable grinding to the different sharpening groove of optional is polished, reaches the life of extension product.

Referring to fig. 2-5, the upper housing is arcuate in shape and the sharpening slot extends from an upper side edge of the upper housing to a lower side edge of the upper housing.

When the design, design the shape of cambered surface with last casing to the sharpening groove of its design, the edge position department of last casing, the contact position of cutter and sharpening wheel is less, and when sharpening wheel loss was too much, the sharpening groove of edge position was difficult for polishing, then selected the sharpening groove that is close to the intermediate position.

Preferably, the knife sharpening grooves are staggered on the end face of the upper shell. The sharpening grooves are staggered to form sharpening positions at different angles.

Optionally, the sharpening wheel comprises a sharpening wheel for rough grinding and a sharpening wheel for fine grinding.

Specifically, the upper shell and the lower shell are fixedly connected through bolts.

Specifically, the lower shell is provided with a first accommodating cavity and more than one second accommodating cavity respectively, the first accommodating cavity is used for installing a motor, and the second accommodating cavity is used for installing a sharpening wheel.

Specifically, the knife sharpening device comprises more than one bearing, and the bearing is mounted on the transmission shaft.

The above description should not be taken as limiting the scope of the utility model, and any modifications, equivalent changes and modifications made to the above embodiments according to the technical principles of the present utility model still fall within the scope of the technical solutions of the present utility model.
