Description
Technical field
The utility model belongs to knife sharpener technical field more particularly to a kind of printing knife sharpener.
Background technology
Knife sharpener is used to finishing blade, and the blade ground is on a straight straight line, compared with gained of whetting a knife by hand
Blade use intensity increase, the service life and its working ability of blade are also correspondingly improved, therefore knife sharpener is
The essential special equipments of industries such as printing, papermaking, packaging, modeling leather, carpenter.
Blade is after long-term work, and the sharpness of the knife edge occurs declining or blade is worn, it is therefore desirable to blade
It carries out reconditioning again to process, different types can be selected to carry out reconditioning to blade according to the length of blade and size.It is existing
Knife sharpener include rack and bistrique assembly, bistrique assembly includes head holder, motor and is fixed on motor shaft front end
Sharpening part.Rack is equipped with two parallel guide rails, is set on head holder there are two sliding slot, two sliding slots are stuck in guide rail, bistrique
Seat moves back and forth on guide rail.Head holder stretches out a transverse arm in the horizontal direction, and head holder is equipped with transverse arm vertical direction
Driving device, transverse arm can move up and down in vertical direction, and motor is fixed on one end of transverse arm.The motor shaft of motor
One end is fixed with the grinding wheel of polishing blade, and the place of rack and motor face is equipped with horizontal knife platform.Blade is placed on knife platform,
Motor drives in driving device to moving down, sharpening part and blade contact friction, to complete sharpening work.
During sharpening, blade needs to move linearly in order to which grinding wheel polishes to the entire blade of blade.It uses
Generally there are two types of modes to control blade movement for present knife sharpener, one is driving knife platform fortune by the way that additional power plant is arranged
It is dynamic, thus with the blade movement on moving knife platform, the second is setting handle and screw structure, knife platform connect with wire rod thread, pass through
Rotational handle drives leading screw rotation to drive the blade on knife platform to move.Blade movement is driven by first way, is increased
The complexity of knife sharpener structure, is not easy to operate；Blade movement is driven by first way, due to being manual control, knife
The movement speed of piece is difficult to control, some positions of blade may be caused excessively to polish, and some positions polishing degree is inadequate.
Utility model content
The purpose of this utility model is to provide a kind of printing knife sharpeners, realize the automatic shifting of knife platform in simple structure
It is dynamic, and the speed of knife platform movement is consistent, ensures the quality of polishing.
In order to achieve the above object, the base case of the utility model is：Print knife sharpener, including power unit, transmission
Unit and support unit, the support unit include the fixed seat that side is provided with cavity, and one is slidingly and sealingly connected in cavity
The knife platform of fixed seat is stretched out in side, and side of the knife platform far from fixed seat is equipped with the clamping device for fixed blade；The power
Unit includes motor and drives the threaded rod of rotation by motor, and the lower end of threaded rod is fixed with the grinding wheel for blade of polishing；Institute
State gear unit include oil pipe, the ram pot of movable block and lower ending opening that is threaded on threaded rod, sliding in ram pot
It is connected with piston, piston rod is connected on piston, the other end of piston rod is fixed on movable block；One end of oil pipe is connected to liquid
The top of pressure cylinder, the other end are connected to side of the cavity far from knife platform.
The operation principle of this base case is：When needing to carry out the processing of reconditioning again to blade, blade is placed on knife
On platform, blade is fixed using clamping device, the blade in bruting process is avoided to shift.Start motor, makes motor toward admittedly
Fixed direction rotation, motor drive threaded rod to rotate, and the grinding wheel of threaded rod lower end rotates together therewith, grinding wheel to blade into
Row reconditioning.At the same time, movable block is moved upwards along threaded rod, and movable block is by piston rod with piston along ram pot
Inner wall upward sliding, the gas (liquid can be also filled in ram pot) in piston press ram pot, since ram pot passes through oil
Pipe is connected to the cavity of fixed seat, the increase of pressure in cavity, the effect that knife platform is under pressure and gradually released cavity, knife platform
On blade moved together with knife platform, i.e., blade moves while grinder buffing blade so that grinding wheel can effectively be beaten
Each position of sharpening sheet.
The advantageous effect of this base case is：Reconditioning is carried out to blade using the present apparatus, utilizes the same motor
Grinding wheel rotation, blade movement are driven simultaneously, is not required to that two power plants are arranged simultaneously, and mill is reduced while simplifying knife sharpener structure
The production cost of knife machine.And since the velocity of rotation of motor is fixed, then the speed that movable block is moved with piston is also fixed, and is ensured
Knife platform is moved together with fixed speed band cutting blade, avoids the occurrence of that grinder buffing is uneven.
Further, it is each filled with hydraulic oil in cavity and ram pot.Hydraulic oil is not easy to be compressed, and has the function of lubrication,
Hydraulic oil is selected to have the effects that stable transmission as driving medium, reduce abrasion.
Further, piston is equipped with the O-ring seal contacted with ram pot inner wall.Setting O-ring seal can enhance work
Leakproofness between plug and ram pot, avoids hydraulic oil from revealing.
Further, further include retarder, the input shaft of retarder and the output axis connection of motor, the output shaft of retarder with
Threaded rod connects.Retarder can effectively reduce the output speed of motor, avoid grinding wheel speed too fast and excessively polish blade.
Further, further include adjusting unit for adjusting fixed seat height, it includes hydraulic cylinder to adjust unit, hydraulic cylinder
Piston rod is connect with fixed seat.The blade height of different size is different, the blade of different size of polishing need to rationally adjust blade with
The distance between grinding wheel enables grinding wheel preferably to polish blade.Can have by operating hydraulic cylinder in this programme
Effect adjusts the distance between blade and grinding wheel, very convenient.
