The stirring rod A6 is fixedly connected with the stirring shaft A601. The stirring rod B61 is fixedly connected with the annular gear 26. The motor output shaft 51 is fixedly connected with the stirring shaft A601. The planar thread disc C3, the planet wheel C31, the planar threaded rod C32, the bidirectional ratchet wheel C34 and the belt wheel C19 are the same in size as the planar thread disc D4, the planet wheel D41, the planar threaded rod D42, the bidirectional ratchet wheel D44 and the belt wheel D191.

The start button 53 on the control module 12 is pressed, the motor 5 rotates positively, the driving belt 11 drives the bevel gear A13 to rotate positively, the bevel gear A13 drives the bevel gear B131 to rotate positively, the bevel gear B131 drives the transmission shaft B56 to rotate positively, the transmission shaft B56 drives the driving disc 49 to rotate positively, the two-way ratchet wheel D44 is driven to rotate positively through the pawl F48, finally the plane threaded rod D42, the plane threaded disc D4, the planet wheel D41 and components thereof are driven to rotate positively, the planet wheel C31 and the plane threaded rod C32 are driven to rotate positively through the toothed synchronous belt 15, the two-way ratchet wheel C34, the plane threaded disc C3 and components thereof are driven to rotate positively, the spiral piece shaft A211 is driven to rotate positively, and the spiral piece A21 is driven to rotate positively, so that feeding is realized.

The motor 5 is reversed by pressing the speed reduction adjustment button 541 on the module control button 121, driving the driving disk 49 to reverse (the pawl F48 is in the idle state, and the motor 5 is powered off). Simultaneously, the electromagnet C241 and the electromagnet D251 (both reversely arranged) are powered to push out the bidirectional pawl C24 and the bidirectional pawl D25 to lock the bidirectional ratchet C34 and the bidirectional ratchet D44 respectively. At the same time, the electromagnet D2 47 is energized to lock the pulley D191 reversely. At this time, the adjusting wheel 14 is rotated counterclockwise) to drive the pulley D191 and the flat threaded disk D4 to reverse. The plane thread disk D4 drives the plane threaded rod D42 to simultaneously radially shrink (stepless adjustment), so that the distance from the center of the planet wheel D41 to the rotation center of the transmission shaft B56 is shortened. The belt wheel D191 drives the belt wheel C19 to rotate clockwise through the crossed belt 1, the belt wheel C19 drives the plane thread disk C3 to rotate clockwise, the plane thread disk C3 drives the plane threaded rod C32 to extend radially (stepless adjustment) at the same time, so that the distance from the center of the planet wheel C31 to the rotation center of the spiral sheet shaft B23 is increased (because the diameters of the belt wheel C19 and the belt wheel D191 are equal, the pitch of the plane thread disk C3 and the plane thread on the plane thread disk D4 is the same, the center distance is unchanged, the circumference of the tooth-shaped synchronous belt 15 is unchanged; i.e. after the speed-down adjusting button 541 is pressed, the electromagnet D2 47 is powered on, the electromagnet D3 471 is powered off, and the speed-up adjusting button 54 is pressed similarly.

The bottom of the storage vat 2 is fixedly connected with the planet carrier 291, the motor output shaft 51 drives the sun gear 29 and the sector gear B281 to rotate (the sun gear 29 is fixedly connected with the sector gear B281), the sun gear 29 drives the gear A27 to rotate, and the gear A27 drives the sector gear A271 to rotate (the gear A27 is fixedly connected with the sector gear A271).

The stop button 55 is pressed, and the motor 5 stops rotating. Meanwhile, the electromagnet C241, the electromagnet D251, the electromagnet D2 47 and the electromagnet D3 471 are all powered off, and the device is in a static state.

When the mixture needs to be taken out, the discharge hole 62 is opened, the speed reduction adjusting button 541 or the speed increase adjusting button 54 is pressed, and the motor 5 is reversed to drive the stirring rod A6 and the stirring rod B61 to rotate, so that the mixture is driven to flow out from the discharge hole 62. Since the adjustment disk 14 is not rotated, the feed ratio is not changed. Since the pawl F48 is in the idle state, no feed is made.

When the speed-up adjusting button 54 or the speed-down adjusting button 541 is pressed, and the adjusting wheel 14 is rotated to a required scale, the planetary wheel C31 and the planetary wheel D41 realize unidirectional rotation due to the pawls E2 and E312 and E411, so as to adapt to the change of the required tooth number caused by the radial change of the toothed synchronous belt 15 in the adjusting process.

The ratchet teeth are radially distributed on the planet wheel C31 and the planet wheel D41, when the motor 5 rotates positively, the pawl E2 312 and the pawl E411 lock the planet wheel C31 and the planet wheel D41 in one direction respectively (namely, the locking state can realize power transmission, the reverse direction is free from motion transmission), the planet wheel C31 drives the tooth-shaped synchronous belt 15 to rotate (the process of transmitting motor power to the planet wheel C is omitted, the 2 nd (after the starting part is pressed down)) of the original specific embodiment, the tooth-shaped synchronous belt 15 drives the plane threaded rod C32 to rotate through the planet wheel D41, and the plane threaded rod C32 drives the bidirectional ratchet C34, the plane threaded disc C3 and components thereof to rotate. When the speed-up adjusting button 54 or the speed-down adjusting button 541 is pressed, the pulley D191 and the flat threaded disk D4 are reversed by rotating the adjusting wheel 14 to the required scale (rotating the adjusting wheel 14 counterclockwise). The plane thread disk D4 drives the plane threaded rod D42 to simultaneously radially shrink (stepless adjustment), so that the distance from the center of the planet wheel D41 to the rotation center of the transmission shaft B56 is shortened. The belt wheel D191 drives the belt wheel C19 to rotate clockwise through the crossed belt 1, the belt wheel C19 drives the plane thread disc C3 to rotate clockwise, the plane thread disc C3 drives the plane threaded rod C32 to extend radially (stepless adjustment) simultaneously, the distance from the center of the planet wheel C31 to the rotation center of the spiral sheet shaft B23 is increased), the planet wheel C31 and the planet wheel D41 realize unidirectional rotation due to the pawls E2 and E411, so that the change of the required tooth number caused by the radial change of the toothed synchronous belt 15 in the adjustment process (the change of the required tooth number caused by the radial distance change in the adjustment process can be compensated by unidirectional rotation of the planet wheel itself) is adapted.

When the adjustment is not needed, the belt wheel D191 drives the belt wheel C19 to rotate through the toothed synchronous belt 15, and the pawl D2 and the belt wheel D191 are in an unengaged state, so that the adjustment wheel 14 is in a static state, and the mixing proportion is not changed. The feeding amount is accurate. The plane thread disk D4 is radially provided with scales, so that the feeding proportion can be accurately adjusted, and the feeding precision is ensured.

Continuously variable part feed power transmission introduction

Introduction of power transmission of mixing mechanism

The motor output shaft drives the sun gear 29 and the sector gear a271 to rotate forward (the sun gear 29 and the sector gear B281 are fixed with the motor output shaft 51), and the sun gear 29 drives the gear a27 and the sector gear a271 to rotate backward (the gear a27 is fixed with the sector gear a 271). Namely, the sun gear rotates positively, the sector gear B rotates positively, and the sector gear A rotates reversely, and the sector gear A and the sector gear B can be meshed with the gear B, namely, the gear B has two steering directions. Because sector gear A and sector gear B are installed in a staggered way, gear B is only meshed (staggered) with any one of the sector gears at the same time, and gear B is in a forward rotation-reverse rotation-forward rotation-reverse rotation alternate meshing state. Because the gear B is meshed with the inner gear ring, the inner gear ring is in an alternate meshed state, so that the inner gear ring continuously rotates positively and negatively, and the aim of secondary mixing is fulfilled.
