(1) the feeding screw rod 4 positively rotates at the initial position to convey the material to the feeding hole 200;
(2) the feed screw 4 moves from the initial position to the feed position;
(3) the feeding screw rod 4 reaches a feeding position, and the material is continuously fed into the processing cup 2 by forward rotation at the feeding position;
(4) after the completion of the feeding, the feed screw 4 is retracted from the feeding position to the home position.
When not to processing cup 2 pay-off, when feed screw 4 was in the initial position promptly, feed screw 4 closed the feed port 200 of processing cup 2, prevent that steam from getting into feed cylinder 3 and leading to the material to become moist, sanitation and reliability, because feed screw 4 can move to the feed position from the initial position, feed screw 4 axial displacement promptly, can open or close feed port 200 through feed screw 4, be equivalent to feed screw 4 and realized the dual function of feeding and valve, not only simpler in the aspect of control, the feeding can be realized through an operation with opening feed port 200, and need not set up the valve alone, the cost can reduce. Diameter D of feed hole 200Hole(s)The material that can satisfy most different grade type passes through, extensive applicability, for example powder, tiny particle material, large granule material etc.. DHole(s)Too small, some beans can not pass through, the diameter of the feeding screw rod is correspondingly smaller, the spiral feeding capacity is reduced, and DHole(s)Too large, it will cause space waste and also improve the sealing requirements of the feed hole.
The forward rotation and the reverse rotation mentioned in the present invention are different from each other in two opposite rotation directions, and are not limited to any particular way, and the forward rotation is a rotation direction in which the material is fed forward, and the reverse rotation is a rotation direction opposite to the forward rotation. While reference is made to the description of the front, rear, etc. directions, reference may be made to fig. 1, where from left to right in fig. 1, the description of the present invention refers to from back to front.
In this embodiment, the axial movement of the feeding screw 4 can be realized by the material, specifically, the feeding screw 4 positively rotates at the initial position to make the material move to the feeding hole 200 and accumulate in the feeding cylinder 3, the rotational resistance along with the feeding screw 4 is larger and larger, so as to cause the blocking rotation of the feeding screw 4, and then the feeding screw 4 is converted from the positive rotation to move from the initial position to the feeding position to open the feeding hole 200.
Feeding screw 4 reachs the feed position, and the material can freely fall into processing cup 2, because the material falls into processing cup 2 back, the resistance of feeding screw 4 lock-rotor disappears naturally, leads to the condition of feeding screw 4 lock-rotor to disappear, and feeding screw 4 begins corotation again and continuously sends the material into processing cup 2.
From the aspect of the structure, the food preparation machine of this embodiment includes feeding motor 6 and feed nut 5, feeding motor 6 drives feed nut 5 corotation, feed nut 5 and feeding screw 4 cooperate, feed screw 4 realizes corotation by the transmission of feed nut 5, 4 stifled back of feeding screw, feeding screw 4 receives the resistance of rotation can be greater than the resistance between feed nut 5 and the feed screw 4, feed nut 5 keeps corotation to lead to feed screw 4 to remove from the initial position to the feed position. After the feeding screw rod 4 moves to the feeding position, the resistance of the feeding screw rod 4 to the material is reduced, and the resistance of the feeding nut 5 to the feeding screw rod 4 enables the feeding screw rod 4 to rotate forwards, so that the feeding is continued. The feed screw 4 comprises a sealing section 41 for closing the feed hole 200 and a spiral section 42 for conveying the material to the stacking of the sealing section 41, the material is stacked on the sealing section 41 to block the feed screw 44, and the feed screw 4 moves axially to let the sealing section 41 open the feed hole 200. The helical section 42 may be a spiral blade with or without a shaft.
For simplifying structure and reduce cost, this embodiment only uses a feeding motor 6 to realize corotation and the reversal of feed nut 5, consequently in order to let feed screw 4 can get back to initial position, and when feeding motor 6 drove feed nut 5 and reverses, feed screw 4 was locked and can't reverse, and feed nut 5 reverses and makes feed screw 4 move to initial position from feed position. Specifically, the feed screw 4 is locked in a reverse rotation mode through the ratchet wheel 7 and the pawl 71, the ratchet wheel 7 is fixed with the feed screw 4, the ratchet wheel 7 rotates along with the feed screw 4 in a forward rotation mode, and the pawl 71 abuts against the ratchet wheel 7 to limit the ratchet wheel 7 to rotate in a reverse rotation mode. In order to enable the ratchet wheel 7 and the feeding screw rod 4 to rotate synchronously and simultaneously not to influence the axial movement of the feeding screw rod 4, the ratchet wheel 7 can be connected with the feeding screw rod 4 through the square shaft 72, the ratchet wheel 7 is fixedly connected with the square shaft 72, the rear end of the feeding screw rod 4 is provided with the square hole 44, and the square shaft 72 is inserted into the square hole 44 to be matched, so that the square shaft 72 and the feeding screw rod 4 cannot move in the circumferential direction, and the square shaft 72 can move relative to the feeding screw rod 4 in the axial direction. It is understood that, instead of the square shaft 72, other shaft bodies having a non-circular cross-sectional shape may be used as long as the synchronous rotation with the feed screw 4 and the mutual movement in the axial direction are achieved.
In order to avoid the phenomenon that the feeding screw rod 4 is excessively moved to cause the clamping of the feeding nut 5, the feeding motor 6 is seriously burnt out, and therefore when the feeding screw rod 4 moves to the initial position from the feeding position, the feeding motor stops working. Specifically, the food processor can control the feeding motor to stop working after judging that the feeding screw 4 returns to the initial position by the position detector, and the position detector can adopt common components such as a position sensor, a microswitch and the like. In addition, the feeding nut 5 may be locked after the feeding screw 4 returns to the initial position, and the food processor may control the feeding motor to stop operating after determining that the feeding screw 4 returns to the initial position according to the increase of the current of the feeding motor.
The feeding barrel 3 is provided with a feeding port 301, the feeding port 301 is located above the spiral section 42, in order to ensure that the feeding screw 4 can still receive the material falling from the feeding port 301 for conveying after moving forward, the dimension of the feeding port 301 in the axial direction of the feeding barrel 3 can be designed to be D, the length of the spiral section 42 in the axial direction of the feeding barrel 3 is L1, the forward moving stroke of the feeding screw 4 is S, L1 is greater than or equal to D + S, namely after the feeding screw 4 moves forward, a part of the spiral section 42 is still located below the feeding port 301. In order to facilitate blanking, a hopper 8 is arranged in the machine body, and the bottom end of the hopper 8 is communicated with the feeding port 301.
The length of the sealing section 41 in the axial direction of the feeding cylinder 3 is L2, and the stroke S of the forward movement of the feeding screw 4 is determined, so that the sealing section 41 can open the feeding hole 200 after the forward movement of the feeding screw 4, and is suitable for feeding most materials, not only powder materials, but also large particles such as soybean materials, so that the S-L2 is designed to be 5-10 mm, that is, the sealing section 41 is 5-10 mm away from the inner side wall of the processing cup 2 after extending into the processing cup 2.
In order to avoid that the material enters the periphery of the sealing section 41 to affect the sealing performance, the sealing section 41 can be located in front of the feeding port 301 when the feeding screw 4 is in the initial position.
In order to improve the sealing performance, a sealing ring can be arranged on the periphery of the sealing section 41, and the frictional resistance of the sealing ring matched with the inner wall of the feeding cylinder 3 is smaller than the frictional resistance of the feeding nut 5 matched with the feeding screw rod 4, so that the feeding screw rod 4 is not influenced to rotate synchronously along with the feeding nut 5.
In this embodiment, the feeding motor 6 is in transmission connection with the feeding nut 5 through a gear mechanism, and the transmission is stable and has certain self-locking capability. Specifically, a driven gear 51 is arranged on the feeding nut 5, a driving gear 61 is arranged on an output shaft of the feeding motor 6, the driving gear 61 is in meshed transmission with the driven gear 51, and bevel gear transmission can be adopted in consideration of space factors.
For feed nut 5 can stabilize rotatoryly, can rotate feed nut 5 and connect the rear end at feed cylinder 3, feed cylinder 3 is connected with the support 11 with 5 axial positioning of feed nut, and support 11 also can support fixedly to feed cylinder 3, improves structural stability. The ratchet 7 and the pawl 71 may be mounted on the bracket 11.
The processing cup 2 comprises a cup body 21 and a cup cover 22, in the embodiment, the feeding cylinder 3 is arranged on the outer peripheral side of the cup body 21, and the feeding hole 200 is positioned on the side wall of the cup body 21. It is understood that the feed cylinder 3 may be disposed above the cap 22, and the feed hole 200 is located in the cap 22.
Example two:
it can be understood that, except for adopting ratchet 7, pawl 71, feed screw 4 realizes the reversal lock through one-way bearing and dies, and feed screw 4 is connected and circumference is fixed with the inner circle of one-way bearing, and the outer lane of one-way bearing is fixed relative to feed cylinder 3, and the inner circle of one-way bearing is followed feed screw 4 corotation, and one-way bearing pins when feed nut 5 reverses and makes feed screw 4 unable reversal.
Other contents not described in this embodiment may refer to embodiment one.
Example three:
