It is empty that four rollers are located at the first space convex arc 21-5 on space cam 21, second space convex arc 21-6, third Between convex arc 21-7, the 4th space convex arc 21-8 farthest away from 21 central axis of space cam, and cross guide rail 15 slide into it is minimum In the state of position, the medial surface of four blades 11 is encircled into round table surface.Four rollers are located at first on space cam 21 Space concave arc 21-1, second space concave arc 21-2, third space concave arc 21-3, the 4th space concave arc 21-4 are near space cam At 21 central axis, and cross guide rail 15 slides into the state of extreme lower position, since the first space concave arc 21-1 and space are convex Take turns the distances of 21 central axis than second space concave arc 21-2 the small 3mm at a distance from 21 central axis of space cam.Therefore it is adjacent Two panels blade 11 partly overlaps, and will not collide interference.
The block cutting method of the space cam formula broccoli automatic dicer is specific as follows:
Step 1: continuing for broccoli handstand to be in place in the empty tray 28 of bottom of the frame feed end, so that west is blue Colored scape is straight up.
Step 2: driving motor 22 drives conveyer belt 13 to move, so that being placed with the charging tray 28 of broccoli from bottom of the frame Feed end to discharging end motion;Encoder detects the rotational speed omega of delivery wheel, 28 movement velocity v=ω × r of charging tray, wherein r is defeated Send the radius of wheel;Light curtain sensor 10 detects the time t that broccoli passes through 10 light curtain of light curtain sensor;Calculate the straight of broccoli Diameter D=v × t.
Step 3: being divided to four blades 11 for two set of blades, the two panels blade being oppositely arranged is a set of blades;Stepping Motor 16 rotates, and space cam 21 is driven to rotate;So that cross guide rail 15 is located in the state of extreme lower position, one of blade The spacing of two panels blade tip center position is L1 in group, the spacing of 11 top center position of two panels blade in another set of blades For L2, L1≤L2, L1=0.5D;Knife rest guide rod 13 drives turning block 33 to rotate under the effect of space cam 21 simultaneously, thus So that dress knife bar overturning, realizes the adjustment of angles of edges.During this, the diameter D of broccoli is bigger, then L1 and L2 are got over Greatly, it fills knife bar axis and the angle of horizontal plane is smaller.
Step 4: driving motor 22 stalls after the charging tray 28 for being placed with broccoli reaches the underface of adjustment mechanism 4.Directly The rotation of galvanic electricity machine, slide bar 20 drive cross guide rail 15 to move downward, so that dress knife bar 14 be pushed to be tilted towards along knife bar sliding rail 12 Lower slider, four cuttings of blade 11 are located at the broccoli immediately below adjustment mechanism 4.
Step 5: stepper motor 16 rotates forward, space cam 21 is driven to rotate, so that four rollers arrive separately at space cam First space convex arc 21-5 on 21, second space convex arc 21-6, third space convex arc 21-7, the 4th space convex arc 21-8 farthest away from At 21 axis of space cam.At this point, four blades 11 are displaced outwardly respectively.During blade 11 is displaced outwardly, it is stuck in blade Broccoli limb on 11 is broken off, and avoids the case where broccoli movement is driven when blade resets.Direct current generator continues to rotate, Slide bar 20 drives cross guide rail 15 to move upwards, and stepper motor 16 inverts, and space cam 21 is driven to rotate, so that four rollers point It is clipped to up to the first space concave arc 21-1, second space concave arc 21-2, third space concave arc 21-3, the 4th space on space cam 21 Concave arc 21-4 is at 21 axis of space cam.
Step 6: repeating Step 2: three, four and five until complete the stripping and slicing of all broccoli to be cut.
Step 7: sieving bouquet and stem after stripping and slicing with sieve, to remove broccoli stem, retains and complete stripping and slicing Bouquet.

Step 5: the driving space cam rotation of the second driving assembly, so that four rollers arrive separately at the first sky on space cam Between convex arc, second space convex arc, third space convex arc, the 4th space convex arc farthest away from space cam axis;At this point, four knives Piece is displaced outwardly respectively;Meanwhile third driving assembly driving cross guide rail moves upwards, the second driving assembly drives space cam Rotation, so that four rollers arrive separately at the first space concave arc on space cam, second space concave arc, third space concave arc, the Four space concave arcs are at space cam axis;
Step 6: repeating Step 2: three, four and five until complete the stripping and slicing of all broccoli to be cut;
Step 7: sieving bouquet and stem after stripping and slicing with sieve.
