Abstract
A knife sharpening device includes a base with a motor and a gear reduction assembly connected thereto. A main shaft is connected to the gear reduction assembly and two grinding disks are mounted on the main shaft. A separation tube is mounted on the main shaft and located between the two grinding disks. Each grinding disk has a spring urging thereto so as to prevent the grinding disks from shaking. A cover is mounted to the base and has slots via which the blades of knives are inserted and ground by the grinding disks.
Description
- The present invention relates to an electrical knife sharpening device that includes a motor to drive two grinding disks via a gear reduction assembly. Two springs are urged on the two grinding disks to let the grinding disks rotate in stable status.
- A conventional electrical knife sharpening device generally includes a motor which drives one or two grinding disks directly so that the rotational speed of the grinding disks is so high that could damage the edges of blades of the knives. Besides, once the grinding disks are not installed at their proper positions, the high rotational speed of the grinding disks will make the grinding disks tremble and generate noise.
- In accordance with one aspect of the present invention, there is provided an electrical knife sharpening device which comprises a base and a motor is connected to the base. A gear reduction assembly is connected to an output shaft of the motor and a main shaft respectively. Two grinding disks are mounted to the main shaft and a separation tube is mounted to the main shaft and located between the two grinding disks. Two springs are mounted on the main shaft and urge the two grinding disks toward the separation tube. A cover is mounted to the base and has slots defined therethrough to access the grinding disks.
- The primary object of the present invention is to provide a knife sharpening device that has a gear reduction assembly connected to the motor and the grinding disks are urged by two springs.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
- BRIEF DESCRIPTION OF THE DRAWINGS
- FIG. 1 is an exploded view to show a knife sharpening device of the present invention;
- FIG. 2 is a perspective view to show the knife sharpening device of the present invention; and
- FIG. 3 is a cross sectional view to show the knife sharpening device of the present invention.
- Referring to FIGS.1 to 3, the knife sharpening device of the present invention comprises a
base 10 having a plurality of separation plates and a plurality ofrecesses motor 20, agear reduction assembly 30 and twogrinding disks 54 are installed in therecesses cover 60 is mounted to the top of thebase 10 by extendingbolts 61 throughtubes 15 on thebase 10 and engaged with thecover 60. An opening is defined in a top of thecover 60 and has twopositions 62 for receiving thegrinding disks 54. Amask 70 is connected to the opening of thecover 60 byscrews 71 and a plurality ofslots 72 are defined through themask 70. - The
motor 20 has anoutput shaft 21 to which aventilation fan 22 and agear reduction assembly 30 are respectively connected to two ends of theoutput shaft 21. Amain shaft 40 is connected to acentral rod 31 for connecting the gears of thegear reduction assembly 30. Twogrinding disks 54 are mounted to themain shaft 40 and aseparation tube 55 is mounted to themain shaft 40 and located between the twogrinding disks 54. Twosprings 53 are mounted on themain shaft 40 and urge the twogrinding disks 54 toward theseparation tube 55. Twogrooves 41 are defined in themain shaft 40 and tworetaining washers 51 are mounted to themain shaft 40 and contact an end of each of thesprings 53. Two C-shaped clips 52 are engaged with the twogrooves 41 to keep theretaining washers 51 in position. Acap 56 is mounted to an end of themain shaft 40. - The
grinding disks 54 are urged by thesprings 53 so that thegrinding disks 54 can rotate in stable and the speed of thegrinding disks 54 is properly because of thegear reduction assembly 30. Theedges 81 of the blades of theknives 80 are inserted in theslots 72 and ground by thegrinding disks 54. - While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
