Background

The existing household full-automatic pasta machine generally comprises a main machine, a stirring component and an extrusion component, wherein the stirring component is arranged on the main machine, and comprises a stirring cup connected with the main machine and a stirring rod arranged in the stirring cup. The extruding component comprises a dough extruding cylinder arranged at the lower part of the stirring cup, a screw rod transversely arranged in the dough extruding cylinder and a die head component arranged at the opening end of the dough extruding cylinder. The die head component comprises a die head support arranged at the opening end of the extruding cylinder in a cylindrical shape, an opening is arranged below the side wall of the die head support, a tile-shaped die head is detachably arranged on the opening, a forming hole is formed in the die head, a die head cover is sleeved outside the die head support, and the die head cover is connected to the opening end of the extruding cylinder in a threaded mode, so that the die head support is locked and fixed on the extruding cylinder. When the noodles are made, firstly, flour and water with corresponding weight are put into the stirring cup, then the motor in the main machine is started to drive the stirring rod to rotate, so that the flour and the water in the stirring cup are uniformly stirred to form flocculent small dough, and the small dough falls into the noodle extruding cylinder. After the dough is uniformly stirred, the motor drives the screw rod to rotate so as to push and extrude the dough falling into the dough extruding cylinder forwards, and the dough is extruded outwards continuously from the forming hole of the die head to form the noodles.

It can be understood that the stirring assembly of the existing pasta machine has the additional function of stirring the flour into dough, thus diversifying the function of the pasta machine. When people need to make flour food such as steamed bread and steamed stuffed bun at home, the flour can be stirred into dough by the flour food machine, so that the trouble of manually kneading the dough can be reduced.

However, the existing pasta machine has the following defects when the flour is stirred into dough: the dough required by making noodles is a small dough in a flocculent shape, while the whole large dough is required by making wheaten foods such as steamed bread, steamed stuffed bun and the like, and accordingly, the water content and the flexibility of the dough are different. That is, the existing pasta machine is focused on mixing water and flour uniformly while mixing flour, and avoiding large dough to facilitate the small dough to enter into the noodle-extruding cylinder and be extruded by the screw to form noodles. The dough required for making the wheaten foods such as steamed bread, steamed stuffed bun and the like is large dough with high water content and good toughness. Therefore, when a user makes dough with the existing mixing assembly, it is poor in effect, and particularly, when the flour is formed into a large dough, the inside of the dough is difficult to be sufficiently kneaded, thereby affecting the toughness of the dough and the mouthfeel of the made pasta.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a wheaten food machine of kneading dough, on the basis of realizing full-automatic preparation noodless, still can stir into the dough that toughness is good with flour to conveniently make the wheaten food of steamed bun, steamed stuffed bun and so on.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the dough kneading machine comprises a main machine with a motor inside and a dough kneading assembly arranged on the main machine, wherein the dough kneading assembly comprises a dough kneading cup, a dough kneading rod arranged in the dough kneading cup and an upper cover arranged at an opening at the upper part of the dough kneading cup, a plurality of dough kneading bulges arranged at intervals in the circumferential direction are arranged on the inner side wall of the dough kneading cup, the dough kneading rod comprises a dough kneading shaft, at least two dough kneading teeth radially arranged on the dough kneading shaft, the lower end of the dough kneading shaft extends out of the dough kneading cup to be in transmission connection with the motor, the distance between the rotating track at the end part of the dough kneading teeth and the dough kneading bulges is s, and s is more than or equal to 1.5mm and less than or equal to 4 mm.

The utility model adds a dough kneading component on the basis of the prior dough machine. When flour is required to be stirred into dough suitable for making steamed bread, steamed stuffed bun and other cooked wheaten foods, a dough kneading cup can be placed on a main machine and positioned, then appropriate amount of flour and water are placed in the dough kneading cup, then a motor is started, the motor drives a dough kneading rod to rotate, and then the flour can be stirred into tough large dough. The dough to be fermented can be kept in the dough kneading cup for static fermentation, and when the dough is fermented, the motor can be started again to stir the dough, so that the fermented dough is exhausted and stirred into tough dough, and the dough can be taken out from the dough kneading cup to prepare the wheaten food.

Particularly, the utility model discloses set up a plurality of kneading archs of interval arrangement in week on the cup inside wall that kneads dough. Thus, when the dough kneading bar stirs the dough, the dough will rotate along the inner side wall of the kneading cup under the centrifugal force.

As shown in figure 1, the dough kneading machine for dough kneading comprises a main machine 1 with a motor 11 inside, a dough kneading assembly 2 arranged on the main machine, the dough kneading assembly comprises a dough kneading cup 21, a dough kneading rod 22 vertically arranged in the dough kneading cup, and an upper cover 23 arranged at an opening at the upper part of the dough kneading cup. The dough kneading rod comprises a dough kneading shaft 221, two dough kneading teeth 222 radially arranged on the dough kneading shaft, the two dough kneading teeth are uniformly distributed in the circumferential direction, and the lower end of the dough kneading shaft extends out of the dough kneading cup and is in transmission connection with the motor.

As can be understood, as the pasta machine, as shown in FIG. 2, the utility model also comprises a stirring component 3 and a squeezing component 4, wherein the stirring component comprises a stirring cup 31, a stirring rod 32 vertically arranged in the stirring cup, and an upper cover 23 covering the opening above the stirring cup. The extruding component comprises a flour extruding cylinder 41 which is integrally and transversely arranged at the bottom of the stirring cup, a screw 42 which is transversely arranged in the flour extruding cylinder and a die head component 43 which is arranged at the opening end of the flour extruding cylinder, and a flour inlet hole 311 is formed at the intersection of the flour extruding cylinder and the stirring cup.

In order to facilitate the good matching of the stirring cup and the dough kneading cup with the host machine, the stirring cup and the dough kneading cup can be made to have basically consistent shapes and sizes, so that the upper cover can be simultaneously suitable for the dough kneading cup and the stirring cup. When noodles are required to be made, the stirring cup can be connected with the main machine, a proper amount of flour and water are placed in the stirring cup, the upper cover is covered at the opening at the upper part of the stirring cup, at the moment, a motor in the main machine is in transmission connection with the stirring rod and the screw rod through a transmission mechanism with two output ends, the motor is started to stir the flour, and then continuous noodles are formed through the extrusion assembly. When dough kneading is needed so as to form a large dough for making steamed bread, steamed stuffed bun and other wheaten foods, the dough kneading cup is arranged and positioned on the main machine, a proper amount of flour and water or yeast are placed in the dough kneading cup, the upper cover is covered on an opening at the upper part of the dough kneading cup, at the moment, a motor in the main machine is in transmission connection with a dough kneading rod through one output end of a transmission mechanism, the motor is started, the flour can be stirred, and then the tough dough is formed. For the wheaten food needing to be fermented, the dough can be kept in the dough mixing cup for fermentation, when the dough is fermented, the motor can be started again to stir the dough, so that the fermented dough is exhausted, and is stirred, extruded and kneaded to form tough dough, so that the dough can be taken out from the dough mixing cup to be made into wheaten food such as steamed bread, steamed stuffed bun and the like. Of course, the other output end of the transmission mechanism is hidden in the host machine and is in an idle state.

In addition, as shown in fig. 1, 3-5 kneading projections 211 are provided on the inner side wall of the kneading cup at intervals in the circumferential direction, and in the present embodiment, the number of kneading projections is 4 and they are uniformly arranged in the circumferential direction. When the dough kneading rod stirs dough, the dough rotates along the inner side wall of the dough kneading cup under the action of centrifugal force. When the dough rotates to the dough kneading bulge, the dough kneading bulge can form an extruding and kneading effect on the dough, so that the effect similar to manual dough kneading is achieved, the dough kneading is uniformly stirred and the toughness of the dough is improved, and the dough is effectively prevented from rotating in the dough kneading cup all the time.

The distance s between the rotating track of the dough kneading teeth end and the dough kneading protrusion can be controlled in the following range: s is more than or equal to 1.5mm and less than or equal to 4mm, so that collision interference between dough kneading teeth and dough kneading bulges can be avoided, the dough can be extruded sufficiently when rotating to the dough kneading bulges, a good hand kneading simulation effect is achieved on the dough, and the overlarge overall dimension of the dough kneading cup is avoided, so that the overall dimension of the wheaten food machine can be reduced.

Preferably, as shown in fig. 3, the kneading projections are a part of a vertical cylindrical surface, so that the distance s between the rotation locus of the ends of the kneading teeth and the kneading projections is gradually decreased and then gradually increased. When the dough rotates to the kneading bulge, the kneading bulge can form a gradually stronger extrusion effect on the dough and then gradually loosen, thereby effectively simulating the effect of manual kneading.

Preferably, the dough kneading teeth are vertical sheets, and comprise a material facing surface 223 vertical to the front side of the rotation direction of the dough kneading teeth and a material backing surface 224 vertical to the rear side of the rotation direction of the dough kneading teeth. When the motor drives the dough kneading rod to rotate, the dough kneading teeth vertical material facing surface can push a large pile of flour or a large block of dough to rotate, thereby being beneficial to improving the dough kneading efficiency. Particularly, when the dough rotates to the first kneading protrusion, the dough is blocked by the kneading protrusion, and at the moment, the dough is squeezed by the material facing surface of the dough kneading rod and the kneading protrusion, so that the dough is flattened. When the flattened dough passes through the first dough kneading protrusion, the subsequent dough kneading teeth continue to push the dough to rotate until the dough touches the second dough kneading protrusion, the material facing surface and the dough kneading protrusions act together at the moment, and the flattened dough is extruded in the other direction again, so that the processes of extruding, flattening, folding and re-extruding similar to manual dough kneading are formed, and the uniformity and the toughness of the dough are effectively improved.

Preferably, the horizontal section of the dough kneading teeth is arranged to be arc-shaped, so that the projection of the dough kneading teeth on the bottom wall of the dough kneading cup is arc-shaped, the material facing surface is an outward convex arc surface, and the material backing surface is an inward concave arc surface. Therefore, under the same radial size of the dough kneading cup and the dough kneading teeth, the convex material facing surface has larger area, thereby being beneficial to fully extruding the dough; on the other hand, when the dough is met the material face propelling movement and is hindered to kneading protruding department, the dough can be flattened to meet the material face and outwards extend along the arc of evagination, thereby be favorable to reducing resistance and the load with the face tooth, and improve the extrusion kneading effect to the dough. That is to say, the convex arc material facing surface is extended from the convex highest position to the edge when extruding the dough, therefore, the extrusion force and the load are increased gradually, and the sudden change of the motor load is effectively avoided.

Further, we can control the height a of the kneading protrusion to the following range: a is more than or equal to 1.5mm and less than or equal to 5mm, so that the dough can be extruded and deformed sufficiently, the dough can be effectively kneaded to have sufficient toughness, the dough can be prevented from being extruded excessively and torn, the integrity and the toughness of the dough can be ensured, the load of a dough kneading rod and a motor can be reduced, the machine is prevented from being stopped due to the overlarge load of the motor, and the service life of the wheaten food machine can be prolonged.

Furthermore, two dough kneading teeth can be arranged on the dough kneading shaft at the same height, so that the two dough kneading teeth have the same stirring, dough kneading and kneading effects, and the dough kneading efficiency can be fully improved. When the flour is stirred into a large dough, one of the dough kneading teeth pushes the dough to rotate in the dough kneading cup, so that the effects of extrusion and kneading are achieved; when the dough turns over the dough kneading teeth and is separated from the dough kneading teeth, the dough kneading teeth at the back can continue to push the dough to rotate, so as to extrude and knead the dough, thereby improving the dough kneading efficiency and ensuring that the dough has stable and consistent quality.

It will be appreciated that when the flour in the dough cup is being mixed into a large dough, the height of the dough will be greater than the height of the flour prior to mixing, and in particular, the height of the dough will be greater as it rolls over the dough teeth. For this reason, we can control the relationship between the distance H from the upper side of the dough kneading tooth to the bottom wall of the dough kneading cup and the height H of the dough kneading cup in the following range: h is less than or equal to H/3, so that the flour in the dough kneading cup can be fully and uniformly stirred by the dough kneading rod to form a tough complete dough, and the phenomenon that the upper cover is opened due to the fact that the dough turns upwards in the dough kneading process or the phenomenon that the flour is adhered to the inner side wall of the upper cover can be avoided.

As mentioned above, the mixing cup and the dough kneading cup can have substantially the same shape and size, that is, the mixing cup and the dough kneading cup have the same height, so that when dough kneading is required, a user can easily put the mixing rod into the dough kneading cup, thereby affecting the dough kneading effect.

As another preferred scheme, as shown in FIG. 4, an avoiding recess 24 is provided at the center of the lower part of the dough kneading rod, and a mounting boss 212 positioned in the avoiding recess is provided at the center of the bottom wall of the dough kneading cup. Thus, the axial length of the dough kneading rod does not coincide with the axial length of the stirring rod. When the user puts the puddler into the cup of kneading dough because of the maloperation in, the puddler can not become good cooperation with the puddler cup-shaped, and the upper cover can be jack-up to the upper end of puddler to remind the user to change the pole of kneading dough, ensure going on smoothly of kneading dough. Meanwhile, the dough kneading teeth have proper height and the distance between the dough kneading teeth and the bottom wall of the dough kneading cup can be ensured, and the dough kneading rod can form good dough kneading effect.

For manufacturing convenience, the dough kneading shaft comprises a plastic shaft body 225 and a metal driving shaft 226 arranged in the shaft body. When the dough kneading cup is placed and positioned on the main machine, the metal driving shaft extends downwards to form reliable transmission connection with the motor through a transmission mechanism in the main machine, and the dough kneading teeth and the plastic rod body form an integral structure through molding. In addition, the lower side of the dough kneading teeth comprises a horizontal edge 227 which is lower than the lower end of the rod body on the outer side, and an avoiding edge 228 which is connected between the edge of the lower end of the rod body and the horizontal edge and is inclined, so that the proper gap between the dough kneading teeth and the bottom wall of the dough kneading cup is kept uniform and consistent, and the residue of flour on the bottom wall of the dough kneading cup during dough kneading is avoided. And the side of dodging that the slope set up both can play the effect of strengthening rib, improves the joint strength between the tooth of kneading dough and the body of rod, is favorable to increasing the area of the tooth of kneading dough again, and then promotes the efficiency of kneading dough.

In order to reliably position the kneading rod, as shown in fig. 1, a positioning hole 231 can be formed in the center of the lower side of the upper cover, and a positioning head 229 which is rotatably connected in the positioning hole is arranged at the upper end of the kneading shaft, so that the upper end and the lower end of the kneading shaft are reliably supported and positioned, the kneading shaft is prevented from shaking during kneading, and the working noise can be reduced.

It should be noted that the same positioning head can be provided at the upper end of the stirring rod. When noodles need to be made, the upper cover can be covered at the opening of the stirring cup, and the positioning head at the upper end of the stirring rod is rotatably connected in the positioning hole of the upper cover, so that the stability of the stirring rod is improved.

Finally, as shown in fig. 1 and 4, a triangular reinforcing rib piece 25 can be arranged between the inner side of the upper side of the dough kneading teeth and the rod body to increase the connection strength between the dough kneading teeth and the rod body, so that the stress concentration phenomenon at the connection part of the upper side of the dough kneading teeth and the rod body is avoided, the area of the dough kneading teeth is increased on the basis of keeping the torque basically stable, which is required by the rotation of the dough kneading rod, and the dough kneading effect during dough kneading is improved, so that the dough is more chewy.
