Described single retarded device plays a significant role in the semi-automatic shredder of the present invention, below describes the operation principle of described single retarded device:
Described knife rest is fixed on a described gear, and described kitchen knife is fixed on knife rest, and described kitchen knife drives described knife rest to rotate counterclockwise, and described knife rest drives a described gear to rotate counterclockwise.Because a described gear, No. two gears engage each other, described No. two gears, No. three gears are fixedly connected with, and described No. three gears, No. four gears engage each other.A described pinion rotation drives described No. four gears and described mandrel to rotate counterclockwise.When described mandrel rotates counterclockwise, described unilateral bearing is in locking state, that is, described mandrel drives described No. five gears to synchronously rotate.Described No. five gears, No. six gears engage each other, and described No. six gears, No. seven gears are fixedly connected with, and described No. seven gears, No. eight gears engage each other, and described No. eight gears are fixed on described nut.Described No. five gears rotate counterclockwise, and described nut rotates counterclockwise.
Described kitchen knife drives described knife rest to rotate clockwise, described mandrel rotates clockwise, described unilateral bearing is in free state, namely, described mandrel cannot drive described No. five pinion rotation, described No. five gears are in free state, and described No. six gears, No. seven gears, No. eight gears, nuts are in free state.
The two ends of described screw mandrel are fixed on described connecting plate, and described connecting plate is fixed on described transverse slat, and described chopping block is fixed on described connecting plate, and described transverse slat is connected described straddle, and described straddle inside is provided with guide pin bushing, and described screw mandrel and described chopping block are for being fixedly connected with.Described chopping block can move along the axis direction of described guide rod, and described screw mandrel can not rotate under the constraint of described chopping block.
The two ends of described guide rod are fixed on described support, and described support is fixed on the shell of described single retarded device.Described stentplacement is on desk.
Below describe the course of work and the operation principle of the semi-automatic shredder of the present invention in detail:
Cutter lifting process: described kitchen knife lifts, described kitchen knife drives described knife rest to rotate counterclockwise, and through the Movement transmit of described single retarded device, described nut rotates counterclockwise.Because described screw mandrel can not rotate, described nut promotes described screw mandrel and relatively moves.Described screw mandrel and described chopping block are for being fixedly connected with.So described kitchen knife lifts, described chopping block relatively described support-moving one segment distance.
Roll setting process: described kitchen knife falls cutting food materials, described kitchen knife drives described knife rest to rotate counterclockwise, through the Movement transmit of described single retarded device, described unilateral bearing is in free state, namely, described mandrel cannot drive described No. five pinion rotation, and described nut is in free state, cannot rotate.The relatively described support of described chopping block remains static.
In the process of cutter lifting and roll setting, realize described chopping block and do batch (-type) feeding along the axis of described screw mandrel, thus cutting is out equably by food to make described kitchen knife.
Constantly repeat this cutter lifting process and roll setting process, can drive described chopping block and the food be fixed on described chopping block travels forward with having beat length by length, food is cut into sheet by described kitchen knife in roll setting process.Food can be held by operator and be fixed on chopping block.
The semi-automatic shredder of the present invention also has the function of the spacing distance automatically regulating two tool marks, thus makes the food of cutting can possess different thickness.
In the process of cutting the dish, the spacing distance of two tool marks has the height of cutter lifting to control in real time, that is, cutter lifting height is higher, and interval is larger.The angle that described kitchen knife lifts is larger, described nut to do the angle rotated counterclockwise larger.It is larger that described nut promotes the distance that described screw mandrel relatively moves, and the distance that the relatively described support-moving of described chopping block is larger, the thickness that described vegetable knife cuts on food is thicker.As a same reason, the angle that described kitchen knife lifts is less, and the thickness that described vegetable knife cuts on food is thinner.
