Description

Grinding stone adjustable angle electric knife sharpener

The novel creation department relates to a grindstone type adjustable angle electric grinder, which is a sharpening structure for grinding tools.

Conventional tool grinding tools, in addition to the commonly used whetstones, also have sharpeners that are milled through the wheel. The use of whetstone sharpening requires more skill, and the user must control the angle and force of the sharpening. Otherwise, it is easy to grind too much to make the tool too weak, or the grinding is not enough to make the tool not sharp enough. This is not easy for the general housewife to get started, and it is easy to cut.

The sharpener that is ground by the rotary wheel has at least one or more grinding wheels, and corresponding to the grinding wheel, a groove is opened for the cutter to be inserted, and the grinding wheel is rotated to grind the cutter, and the sharpener structure is as follows. The prior art application of the multi-directional grinding knife sharpener applies the new application No. 100211018, which focuses on the grinding of the cutting edge of the tool, and if the tool only grinds the cutting edge, the initial effect is good, and the later stage is good. It will lead to the unfavorable condition of the tool grinding, so the tool life can be quickly reduced and it needs to be avoided.

In view of the above-mentioned shortcomings, the creators of this novel believe that they have the urgent need to make corrections. They have been engaged in the design and manufacture of related products for many years, and they have always adhered to the excellent design concept, and researched and created the above disadvantages. After continuous efforts, the company finally launched this new type of grindstone adjustable angle electric grinder, which enhances the product's effectiveness by correcting the excellent product structure.

The main purpose of this new creation is to improve the electric knife sharpener to improve the safety of the sharpening knife, the convenience of operation and the sharpness and durability of the tool after grinding.

For the purpose of the foregoing disclosure, the novel grindstone adjustable angle electric grinder includes a drive assembly, an auxiliary sharpening assembly and an optional alternative sharpening member, the drive assembly having an outer support body. A driving member and a collet mounted on the top end of the driving member are respectively disposed inside the outer supporting body; the auxiliary sharpening assembly has a body, and the base body is provided with an assembling hole for mounting Above the outer support body, the assembly hole can be corresponding to the upper portion of the chuck, and the guide body is respectively provided with a guiding block on both sides of the assembly hole, and the two guiding blocks are symmetrical with each other and The two guiding blocks have a vertical guiding surface and a concave notch respectively above and below the side surface; the sharpening member is detachably assembled on the chuck and has a tapered shape The polishing body has a polishing surface on the surface thereof, and the bottom of the polishing body has an assembly body; the assembly body is configured to pass through the assembly hole and be assembled with the chuck, and the polishing system is located after the assembly Between two guiding blocks, and The grinding surface is located below the guiding surface, by which the driving member is driven to drive the chuck and the sharpening member to rotate, so that the cutting edge gradually contacts the grinding surface against the guiding surface, and the light stroke is made. The blade can be ground, so that the operation is better controlled, and the safety of the sharpening blade is relatively improved, and the guiding surface assists the accuracy of the grinding position, thereby greatly improving the product performance and having industrial utilization value.

The invention relates to a grinding stone type adjustable angle electric knife sharpening machine, wherein the driving component is electrically connected to a power source for supplying electric power, and the power source is taken out, and the power source is capable of taking out charging or the driving component. It is also possible to directly connect the plug to the external room to obtain the required power.

The novel grinding stone type adjustable angle electric knife sharpener, the driving component can use a DC motor, and the driving component is more electrically connected to a speed controller for controlling the rotation speed, and the speed controller A PWM controller can be used, which allows the sharpeners to rotate at different speeds to provide different sharpening requirements.
