The utility model has the advantages of simple structure and small size; besides, the utility model is portable; the utility model is convenient in use and is suitable for sharpening various hand knives and small rotary knives, cutting knives and chopping knives for machine use, and the utility model can be switched on at any time to efficiently sharpen the knives to be knife-edged with time saving; compared with the mode of manually sharpening the knives, the efficiency of the utility model is raised by several times, the hardness of the knives can be kept unchanging, and the utility model is safe in use.

Description

The small-sized electric knife sharpener of band tank

The utility model belongs to knife sharpener, particularly a kind of portability knife sharpener with tank.

Be used for the cutter of cutting (comprise and cut, revolve, sheet, cut, split etc.) action at present, need often temper, make it to recover sharp.Temper cutter and can or use the abrasive machine manual operations on grinding stone, also available grinding machine, but temper manual-operated cutter, except that only a few adopted complicated and expensive automation, the overwhelming majority was manual operations.The manual sharpening both required great effort on grinding stone, and be consuming time again, when particularly tempering original new cutter, more difficult; Whet a knife with abrasive machine, cutter can generate heat inevitably, makes quenched cutter tempering even annealing.Hardness reduces greatly, and influence is used, and can damage cutter when serious.Use general grinding machine, only be applicable to the cutter that tempers the blade surface regular shape, do not grind hand cutting tool.Though it is automatic grinding machinery adaptability is stronger, complicated and expensive.Moreover various grinding machines are all very heavy, are unsuitable for carrying and the use of flowing.

The purpose of this utility model provides a kind of portability knife sharpener with tank, overcomes the shortcoming and defect of prior art.Manual holystone cutter is time-consuming in order to solve, effort and use abrasive machine to whet a knife to make the blade deliquescing even damage the problem of cutter: Mi mends existing machinery or the expensive complicated or discomfort of whetting a knife and tempers hand cutting tool, the inconvenience shortcoming that moves, carry again,

The purpose of this utility model is achieved in that

A kind of portability knife sharpener with tank, it is characterized by: the water-fast grinding wheel locking of electric knife grinder is at the middle part of driven axle, the driven axle two ends have rolling bearing to accept to be installed on the frame, motor on the frame connects driven axle by transmission system, tank is contained in the outside of emery wheel the latter half, just covers the latter half of emery wheel, and with emery wheel and driven axle enough gaps is arranged, bottom of gullet is equipped with the raft that discharges water, and transmission system is belt and belt pulley.Bottom of gullet is equipped with the raft that discharges water,

The utility model has the advantages that:

Solved that manual holystone cutter is time-consuming, effort and use abrasive machine to whet a knife to make the blade deliquescing even damage the problem of cutter; Mi mends to have showed has the machinery of sharpening or expensive complexity or discomfort to temper hand cutting tool, the inconvenient again shortcoming that moves, carries, the advantage of the various sharpening modes of the utility model collection, higher for a kind of portable efficient, save muscle power, when tempering, can cool off the electric knife grinder of cutter simultaneously.The portable electric knife grinder of band tank is simple in structure, volume is little, portability.It is easy to use, is applicable to temper various hand cutting tools and small-sized machine with revolving cutter, cutting knife, chopper, can connect power supply at any time, saves time at short notice, sharp the cutter mill efficiently.It raises the efficiency several times than manual the sharpening, can keep cutter hardness constant.Because speed of grinding wheel is unhappy, this machine is safe in utilization.

Below in conjunction with description of drawings embodiment:

Fig. 1 is the portability knife sharpener structure side view of band tank

Fig. 2 is the portability knife sharpener structure vertical view of band tank

Structural principle: water-fast grinding wheel 1 locking of electric knife grinder is at driven axle 2 middle parts, the driven axle two ends have rolling bearing 3 to accept to be installed on the frame 4, motor on the frame reaches driven axle to power by transmission system belt 5 and belt pulley 6, make emery wheel by predetermined medium speed's rotation, tank 7 (metal or engineering plastics are made) covers the emery wheel Lower Half, and with emery wheel and driven axle enough gaps is arranged, and bottom of gullet is equipped with the raft 8 that discharges water, when needing, can open the water in the discharge channel.

Using method: before using, close the raft that discharges water, an amount of in the water adding groove, water-fast emery wheel bottom is immersed in the water, when the connection power supply was started shooting rotation, the emery wheel of rotation constantly took up water, formed water membrane at wheel face.When the user hands cutter when abrasive machine is operated, need only exert oneself slightly cutter is pressed above emery wheel, will grind off one deck to the part that needs attenuate very soon, make the blade sharp.Simultaneously, the thick moisture film on the emery wheel can absorb the heat that produces in the sharpening, and takes away rapidly.Make the unlikely rising of cutter temperature, maintain blade hardness.And moisture film also can reduce resistance and noise when whetting a knife.

Claims (3)

1, a kind of portability knife sharpener with tank is characterized by; The water-fast grinding wheel locking of electric knife grinder is at the middle part of driven axle, the driven axle two ends have rolling bearing to accept to be installed on the frame, motor on the frame connects driven axle by transmission system, tank is contained in the outside of emery wheel the latter half, just cover the latter half of emery wheel, and enough gaps being arranged with emery wheel and driven axle, bottom of gullet is equipped with the raft that discharges water.
