Description

Technical Field

[0001] The utility model relates to the technical field of knife sharpeners, in particular to a double-head knife sharpener. Background Art

[0002] Wood boards are a commonly used raw material in the home furnishing field. By cutting and other finishing processes on designated wood, well-made wood boards can be obtained, thus providing raw materials for household items. At present, there are many forms of cutting tools used for wood board processing, including disc-shaped tools for direct cutting of wood boards, and a long strip of tools mainly used for rotary cutting of wood boards during processing. This type of tool has the advantages of fast rotation and clean cutting, and this type of tool requires a sharpener for grinding and maintenance.

[0003] The existing knife sharpener has a set of grinding heads that can grind the back face of the knife that needs to be sharpened. However, for double-angle flat-type tools, there are two planes that need to be sharpened. In this way, the general knife sharpener is a little unsuitable. Two grinding processes are required to complete the grinding process of a tool, which is time-consuming, labor-intensive and inefficient.

[0004] For example, the double-grinding-head knife sharpener disclosed in Chinese patent CN203141239U adopts a double-grinding-head structure and adds a secondary grinding head, so that the main rear surface of the double-angle flat-type tool is ground by a grinding head of a conventional knife sharpener while the newly added secondary grinding head can grind its secondary rear surface. Moreover, since the rotation center line of the secondary grinding head intersects with the rotation center line of the grinding head in space, the angle between the two planes ground is consistent with the required angle between the main rear surface and the secondary rear surface of the tool. The grinding of the double-angle flat-type tool, which originally required two processes, can be completed in one step in one process, thereby improving work efficiency and reducing production costs.

[0005] However, when the knife sharpener is grinding the knife, the surface temperature of the knife rises. When the temperature is too high, it will cause damage to the knife.

[0006] We urgently need to provide a double-ended knife sharpener for this reason. Utility Model Content

[0007] The utility model aims to provide a double-head knife sharpener to solve the problem in the background art that when the knife is sharpened, the surface temperature of the knife rises, which may cause damage to the knife when the temperature is too high.

[0012] Preferably, the knife sharpening device further comprises a second motor and a grinding wheel, wherein the second motor is fixedly mounted on one side of the connecting frame, and the grinding wheel is fixedly mounted on an output end of the second motor.

[0013] Preferably, the front and rear ends of the movable plate are respectively provided with thread grooves and limit holes, and the two movable plates are driven to move left and right through the cooperation of the transmission member and the movable plate, so as to facilitate the adjustment of the positions of the two knife sharpeners.

[0014] Preferably, a connecting hole with a diameter equal to that of the guide rod is opened inside the connecting block, and the guide rod passes through the connecting hole. The guide rod passes through the connecting hole opened in the connecting block, thereby guiding the movement of the connecting frame, making it convenient for the connecting frame to drive the grinding wheel to move up and down and adjust the height of the grinding wheel.

[0015] Preferably, a water leakage hole is provided on the upper surface of the base, and a collecting chamber is provided inside the base. When the tool is sharpened, cold water sprayed from the nozzle cools the tool and then enters the collecting chamber to collect waste water.
