when kneading dough is needed, a user inputs relevant parameters through a control panel arranged on the side surface of the mounting arm 21, then the control panel controls the operation of the dough kneading machine according to the parameters input by the user, meanwhile, when kneading dough, the user firstly controls the lifting seat 2 to move through the control panel, so that the lifting seat 2 drives the mounting arm 21 to move upwards, so that the rotating shaft 4 and the stirring rack 41 on the rotating shaft 4 move upwards and leave the dough basin 3, the user can conveniently add flour and auxiliary materials into the dough basin 3, then the user controls the lifting seat 2 to move downwards through the control panel, drives the mounting arm 21 to move downwards, so that the rotating shaft 4 and the stirring rack 41 on the rotating shaft 4 reenter the dough basin 3, meanwhile, the water tank 22 tightly attached to the lifting seat 2 is arranged on the base 1, after the user adds the flour and the auxiliary materials into the dough basin 3, the user adds water corresponding to the flour into the water tank 22, then the user sequentially starts the water pump and the motor in the mounting arm 21 through the control panel, so that water in the water pump 22 is firstly pumped into the dough basin 3 through the water pump (the water pump is positioned above the rotating shaft 21 and the rotating shaft 4, the water pump is directly pumped into the water outlet 4 of the rotating shaft 4, and the stirring rack 41, and the water pump is directly pumped into the water outlet of the stirring rack 4, and the stirring roller 4 is directly pumped to be directly after the water pump is pumped;

meanwhile, the water tank 22 is arranged on the base 1, and water in the water tank 22 is pumped by the water pump positioned in the mounting arm 21 and added into the washbasin 3, so that in the dough kneading process, a user does not need to manually add water into the washbasin 3, and the user can pump and pump the water in the water tank 22 into the washbasin 3 only by controlling the water pump on the control panel, so that the proportion between flour and water in the washbasin 3 is adjusted, and the good quality of the kneaded dough is ensured;

meanwhile, in the dough kneading process, the motor in the mounting arm 21 drives the rotating shaft 4 to rotate, so that the stirring frame 41 mounted on the rotating shaft 4 rotates, and the mixture of the flour and the water in the basin 3 is stirred and gradually mixed to become dough;

meanwhile, in the dough kneading process, the extrusion roller 4 is close to the inner wall of the washbasin 3, and the extrusion roller 4 and the mounting rod 53 can rotate relatively, so that in the processes that the extrusion roller 4 rotates around the rotating shaft 4 and the extrusion roller 4 rotates, certain extrusion and kneading effects can be generated on dough between the extrusion roller 4 and the inner wall of the washbasin 3, the dough is extruded and kneaded by the extrusion roller 4, the flour and water in the dough are further uniformly mixed, the dough kneading speed is increased, the dough kneading effect is improved, the dough is extruded and kneaded by the extrusion roller 4, the dough processing effect in manual dough kneading can be simulated to a certain degree, the formed dough is enabled to be more chewy and tough, and the made dough is more delicious.

As an embodiment of the present invention, the side wall of the basin 3 is provided with a convex block 31, the cross section of the convex block 31 is semicircular, the side wall of the basin 3 is uniformly provided with a plurality of convex blocks 31, the surface of the convex block 31 is provided with a twill 32, and the inclination direction of the twill 32 is the same as the rotation direction of the rotating shaft 4;

in the process of rotating the extrusion roller 4 and extruding and kneading the dough, the convex blocks 31 arranged on the side wall of the washbasin 3 generate certain blocking effect on the dough, so that the resistance of the dough in flowing is increased, and the dough is prevented from sliding and rotating relatively between the extrusion roller 4 and the inner wall of the washbasin 3 when the extrusion roller 4 extrudes and kneads the dough, thereby improving the extruding and kneading effects of the extrusion roller 4 on the dough and ensuring the prepared dough to be stiff, tough and good in taste;

meanwhile, in the dough kneading process, when the extrusion roller 4 drives and extrudes and kneads dough, the dough can contact the twill 32 on the convex block 31, because the twill 32 is arranged on the convex block 31, and the inclined direction of the twill 32 is the same as the rotating direction of the rotating shaft 4, therefore, the dough can be influenced by the twill 32, so that the dough moves towards the bottom of the basin 3, and the dough is ensured to be always positioned at a position close to the bottom in the basin 3 in the dough kneading process as much as possible, so that the dough is prevented from moving towards the opening direction of the basin 3 in the moving process, the dough is stained to the upper end of the rotating shaft 4 close to the mounting arm 21 or the upper end of the dough exceeds the upper surface of the basin 3, so that the dough drops from the opening of the basin 3, meanwhile, because the dough is influenced by the twill 32 to move towards the bottom of the basin 3 in the moving process, so that the dough is subjected to a certain pressure pointing to the bottom direction of the basin 3, the dough extruding and kneading effect is further improved, and the dough kneading effect is achieved, and the dough kneading effect is enabled to be chewy, and the dough is good in the prepared is good in the toughness and the taste;

simultaneously, because basin 3 is made for the punching press mode, set up behind protruding piece 31 on the inside wall of basin 3, the position that corresponds appears sunken on the lateral wall of basin 3, through set up the arch that corresponds each other with this sunken on the inner wall of the fixed cylinder 11 on base 1, can make basin 3 place fixed cylinder 11 in later keep stable, avoid at the dough in-process, basin 3 receives agitator 41, the effect of squeeze roll 4 and dough, lead to basin 3 to appear rotating, thereby avoid basin 3 to rotate and influence the effect of dough, and simultaneously, because basin 3 through with fixed cylinder 11 between sunken and protruding mutual location, it is fixed, therefore, when using, rise when installation arm 21, drive pivot 4, agitator 41, after squeeze roll 4 left basin 3, the user can between with basin 3 upwards mentioning, thereby take basin 3 down from the dough mixer, convenience of users finishes the dough that makes with the dough, and to the dough that the user finishes, and clear up the dough, and clear up the use the reduction back.

As an embodiment of the present invention, the mounting rod 53 is divided into two sections from a middle position, the two sections of mounting rod 53 are connected to each other through a connecting spring 54, an encapsulating rubber 55 is wrapped outside the connecting spring 54, and the cross section of the encapsulating rubber 55 is the same as that of the mounting rod 53;

in the dough kneading process, the hardness of the dough can be different due to different proportions of the added flour and the added water, when the hardness of the dough is relatively large or the volume of the dough between the extrusion roller 4 and the inner wall of the basin 3 is relatively large, the extrusion roller 4 is stressed greatly, so that the extrusion roller 4 is blocked, the possibility of extruding and kneading the dough cannot be realized, the quality of the prepared dough is influenced, and meanwhile, if the clamping time of the extrusion roller 4 is long and a user cannot find the situation in time, the situations that a motor in the mounting arm 21 is burnt out, and the mounting rod 53 on the rotating shaft 4 and the stirring frame 41 deform can be caused, so that the normal use of the dough kneading machine is influenced;

meanwhile, the mounting rod 53 is separated from the middle position and is connected by using the connecting spring 54, so that when the squeeze roller 4 rotates, the relative position between the squeeze roller 4 and the rotating shaft 4 can have a certain change space, and when the volume of dough between the squeeze roller 4 and the inner wall of the basin 3 is relatively large, the position of the squeeze roller 4 is shifted to a certain extent under the action of pressure, so that the squeeze roller 4 can normally cross the convex block 31 on the inner wall of the basin 3, the squeeze roller 4 is ensured to normally squeeze and knead the dough, and the phenomenon that the squeeze roller 4 is clamped at the convex block 31 on the inner wall of the basin 3 due to the relatively large volume of the dough, so that the squeeze roller 4 forcibly squeezes the dough under the action of the motor, which causes the deformation of the mounting rod 53 and the stirring frame 41 or causes the burning of a circuit and a motor in the dough kneading machine, and affects the normal use of the dough kneading machine;

simultaneously, because connecting spring 54 is outside to be wrapped up through encapsulation rubber 55, make the flour-mixing machine when using, connecting spring 54 can not contact the inside dough of basin 3, thereby the effectual flour residue that appears on avoiding connecting spring 54, increase the degree of difficulty of the follow-up clearance of user, and simultaneously, wrap up connecting spring 54 through encapsulation rubber 55, also can avoid connecting spring 54 in use to contact external environment, lead to connecting spring 54's surface impaired, the corrosion, influence the normal use of flour-mixing machine.

As an embodiment of the invention, a cavity 51 is opened inside the squeeze roll 4, outflow holes 52 communicated with the cavity 51 are uniformly opened on the surface of the squeeze roll 4, a communication hole 56 is opened inside the mounting rod 53, and the communication holes 56 between the mounting rods 53 at both ends are communicated with each other through a water pipe;

an inlet hole 43 is formed in the rotating shaft 4, the communication hole 56 is communicated with the inlet hole 43, a connecting ring 42 is mounted on the rotating shaft 4, a ring groove 422 is formed in the inner surface of the connecting ring 42, a connection hole is formed in the rotating shaft 4, the inlet hole 43 is communicated with the ring groove 422 through the connection hole, a pipeline 421 is mounted on the connecting ring 42, and the pipeline 421 is used for sending water into the connecting ring 42;

the pipe 421 on the connecting ring 42 is connected to the water outlet of the water pump in the mounting arm 21, so that when the dough kneading machine works, the water pump can pump the water in the water tank 22 on the base 1 into the ring groove 422 on the connecting ring 42 through the pipe 421, so that the water enters the inlet hole 43 in the rotating shaft 4 from the connecting hole, and the rotation of the rotating shaft 4 cannot interfere with the entering of the water flow because the rotating seal is maintained between the connecting ring 42 and the rotating shaft 4, and then the pumped water can enter the washbasin 3 from the outlet hole 52 and be mixed with the flour in the washbasin 3 because the outlet hole 52, the cavity 51, the communicating hole 56 and the inlet hole 43 are sequentially communicated;

meanwhile, as the extrusion roller 4 rotates in the washbasin 3, the extrusion roller 4 is contacted with the flour in the washbasin 3 at the initial stage of dough kneading, so that the water flowing out of the outflow hole 52 on the extrusion roller 4 can be fully mixed with the flour in the washbasin 3, and the situation that the flour in the washbasin 3 is agglomerated and is not easy to stir uniformly due to the fixed position of the water outlet when the dough kneader injects water into the washbasin 3 is avoided, so that pimples exist in the dough prepared by the dough and the surface is not smooth, and the taste of the wheaten food prepared by the dough is further influenced;

meanwhile, because the outlet 52 is arranged on the squeeze roller 4, in the dough kneading process, a user can add water into the washbasin 3 according to the actual situation of the dough, the user does not need to stop the operation of the dough kneading machine, the rotating shaft 4, the stirring frame 41 and the squeeze roller 4 are moved out of the washbasin 3 and then added with water into the washbasin 3, the user can directly control the water pump in the mounting arm 21 through the control panel, so that the water in the water tank 22 is pumped into the washbasin 3 by the water pump, meanwhile, after the pumped water is discharged from the outlet 52 on the squeeze roller 4, the water can directly contact with the dough, the water is uniformly added into the washbasin 3, the water is uniformly distributed in the dough, the dough is softer, the surface of the prepared dough is smoother, and the cooked wheaten food made by the dough has good mouthfeel.

As an embodiment of the present invention, the communication hole 56 passes through the inside of the packing rubber 55;

the connecting spring 54 is wrapped by the packaging rubber 55, so that the space between the two sections of the mounting rods 53 is completely filled, holes can be formed in the packaging rubber 55, the communication holes 56 penetrate through the packaging rubber 55, the communication holes 56 are prevented from being communicated with each other by using water pipes between the two sections of the mounting rods 53, the situation that the water pipes and water pipe joints are stained with dough in the subsequent use process is avoided, the dough is inconvenient for a user to clean the dough after the dough kneading machine is used, and meanwhile, the situation that the water pipes are broken due to overlarge acting force in the use process due to the fact that the water pipes are contacted with the dough and the normal use of the dough kneading machine is influenced can be avoided;

meanwhile, as a first embodiment, a plurality of sets of connecting springs 54 are used for connecting two sections of the mounting rods 53, then when the communication hole 56 passes through the packaging rubber 55, the communication hole 56 is positioned between the sets of connecting springs 54, and meanwhile, by using the plurality of sets of connecting springs 54, the reliability and the elasticity of the connecting springs 54 for connecting the two sections of the mounting rods 53 can be ensured, so that the squeeze roll 4 is easy to move when being subjected to a large pressure, and damage is avoided;

meanwhile, as a second embodiment, a single group of connecting springs 54 is used for connecting the two end mounting rods 53, and then when the communicating holes 56 penetrate through the packaging rubber 55, the communicating holes 56 are located inside the packaging springs, and meanwhile, when the single group of connecting springs 54 is used for connecting the two end mounting rods 53, the diameter of the connecting springs 54 is relatively thick, so that the connecting springs 54 are difficult to deform in use, and further the extrusion rollers 4 can bear a larger acting force and move, so that the extrusion rollers 4 have a relatively larger acting force for extruding and kneading dough, and the extruding and kneading effects on the dough are improved.

As an embodiment of the present invention, a closing plug 521 is installed in the outflow hole 52, a water outlet seam is formed through the closing plug 521, and the water outlet seams of the closing plug 521 are close to and closed in a normal state;

since the outflow hole 52 is located on the squeeze roller 4, and the squeeze roller 4 needs to squeeze and knead dough, when no water flows out of the outflow hole 52, the dough easily enters the outflow hole 52 when the squeeze roller 4 squeezes, so as to seal the outflow hole 52, therefore, a sealing plug 521 is installed in the outflow hole 52 for protection, so as to avoid that when the squeeze roller 4 squeezes and kneads dough, the dough enters the outflow hole 52, so that the outflow hole 52 is sealed, meanwhile, since a water slit is formed on the sealing plug 521, when water needs to be added into the basin 3, under the pressure of water in the outflow hole 52, the water slit on the sealing plug 521 is squeezed open, so that the sealing plug 521 is opened, water flows out from the water slit on the sealing plug 521 to the basin 3, so as to finish water addition, and meanwhile, when no water exists in the outflow hole 52, due to the self-elastic influence of the sealing plug 521, the side walls of the water slit are mutually attached, so as to seal the water slit, so as to avoid that when external flour and dough are squeezed and rotated, and squeezed into the sealing plug 521, and are normally used.

As an embodiment of the present invention, a silica gel layer 57 is installed on the surface of the squeeze roll 4, a discharge slit 571 is opened on the surface of the silica gel layer 57, and the discharge slit 571 is connected to the cavity 51 on the squeeze roll 4;

because the silica gel layer 57 is arranged on the surface of the squeeze roller 4, and the silica gel layer 57 has elasticity, so that the discharge slot 571 in the silica gel layer 57 can be squeezed by the silica gel layer 57 when no water is discharged, the discharge slot 571 is sealed, the situation that flour or dough enters the discharge slot 571 due to the rotation of the squeeze roller 4 in the process is avoided, the holes in the squeeze roller 4 are blocked, the subsequent addition of water into the basin 3 is influenced, meanwhile, the quantity of the flour adhered to the surface of the squeeze roller 4 in the dough kneading process is reduced by the silica gel layer 57, and a user can clean the dough kneading machine conveniently.

As an embodiment of the present invention, a buffer cavity 572 is formed in the silicone layer 57, and the buffer cavity 572 is not in contact with the discharge slit 571;

after the buffer cavity 572 is arranged in the silica gel layer 57, the silica gel layer 57 is easier to deform after being pressed, so that the dough is extruded and kneaded by the squeeze roller 4, a part of deformation can be provided, meanwhile, the hardness of the silica gel layer 57 is obviously smaller than the strength of the connecting spring 54, the position of the squeeze roller 4 is kept relatively stable by the connecting spring 54, so that the dough is extruded and kneaded, the silica gel layer 57 deforms firstly, then the connecting spring 54 deforms, the squeeze roller 4 moves in the washbasin 3 conveniently, the squeeze roller 4 is convenient to pass through the convex block 31 on the washbasin 3, the load of the motor is reduced, and the motor overload is avoided.

The specific working process is as follows:

when dough kneading is needed, a user inputs relevant parameters through a control panel arranged on the side face of the mounting arm 21, then the control panel controls the operation of the dough kneading machine according to the parameters input by the user, meanwhile, when dough kneading is needed, the user firstly controls the lifting seat 2 to move through the control panel, so that the lifting seat 2 drives the mounting arm 21 to move upwards, so that the rotating shaft 4 and the stirring rack 41 on the rotating shaft 4 move upwards and leave the dough basin 3, the user can conveniently add flour and auxiliary materials into the dough basin 3, then the user controls the lifting seat 2 to move downwards through the control panel, drives the mounting arm 21 to move downwards, so that the rotating shaft 4 and the stirring rack 41 on the rotating shaft 4 reenter the dough basin 3, meanwhile, the water tank 22 tightly attached to the lifting seat 2 is arranged on the base 1, after the user adds the flour and the auxiliary materials into the dough basin 3, the user adds water corresponding to the flour into the water tank 22, then the user sequentially starts the water pump and the motor in the mounting arm 21 through the control panel, so that water in the water tank 22 is pumped into the dough basin 3 through the water pump, after the flour is added, the water is added, the motor 4 is started, the rotating shaft 4 and the extruding roller is started, and the extruding roller 4, and the extruding roller is started;

meanwhile, as the water tank 22 is arranged on the base 1, and water in the water tank 22 is pumped by the water pump positioned in the mounting arm 21 and added into the wash basin 3;

meanwhile, in the dough kneading process, because the extrusion roller 4 is close to the inner wall of the basin 3 and the extrusion roller 4 and the mounting rod 53 can rotate relatively, certain extrusion and kneading effects can be generated on the dough between the extrusion roller 4 and the inner wall of the basin 3 in the processes of rotation of the extrusion roller 4 around the rotating shaft 4 and rotation of the extrusion roller 4;

in the process that the extrusion roller 4 rotates and extrudes and kneads dough, the convex blocks 31 arranged on the side wall of the basin 3 generate certain barrier effect on the dough, and the resistance of the dough during flowing is increased;

meanwhile, in the dough kneading process, when the extruding roller 4 drives, extrudes and kneads dough, the dough can contact the twill 32 on the convex block 31, and because the twill 32 is arranged on the convex block 31 and the inclined direction of the twill 32 is the same as the rotating direction of the rotating shaft 4, the dough can be influenced by the twill 32, so that the dough moves towards the bottom direction of the basin 3;

by separating the mounting rod 53 from the middle position and connecting the mounting rod with the connecting spring 54, the relative position between the squeezing roller 4 and the rotating shaft 4 can have a certain variation space when the squeezing roller 4 rotates, so that when the volume of dough between the squeezing roller 4 and the inner wall of the basin 3 is relatively large, the position of the squeezing roller 4 is deviated under the action of pressure to ensure that the squeezing roller 4 can normally cross the convex block 31 on the inner wall of the basin 3;

meanwhile, the connection spring 54 is wrapped by the packaging rubber 55, so that the connection spring 54 does not contact the dough in the basin 3 when the dough mixer is used;

the pipe 421 on the connecting ring 42 is connected to the water outlet of the water pump in the mounting arm 21, when the dough kneading machine works, the water pump can pump the water in the water tank 22 on the base 1 into the ring groove 422 on the connecting ring 42 through the pipe 421, so that the water enters the inlet hole 43 in the rotating shaft 4 from the connecting hole, and then, as the outlet hole 52, the cavity 51, the communication hole 56 and the inlet hole 43 are sequentially communicated, the pumped water can enter the washbasin 3 from the outlet hole 52 and be mixed with the flour in the washbasin 3;

a hole is formed in the sealing rubber 55 so that the communication hole 56 passes through the sealing rubber 55;

meanwhile, as a first embodiment, a plurality of sets of the connecting springs 54 are used for connection between two pieces of the mounting rod 53, and thereafter, when the communication hole 56 is passed through the encapsulating rubber 55, the communication hole 56 is located between the sets of the connecting springs 54;

meanwhile, as a second embodiment, a single set of connecting springs 54 is used for connection between both end mounting rods 53, and then, when the inside of the packing rubber 55 in the communication hole 56 is passed, the communication hole 56 is located inside the packing spring;

the sealing plug 521 is arranged in the outflow hole 52 for protection, so that the situation that dough enters the outflow hole 52 when the squeezing roller 4 squeezes and kneads the dough is avoided, meanwhile, as the sealing plug 521 is provided with a water outlet seam, when water needs to be added into the basin 3, the water outlet seam on the sealing plug 521 is squeezed open under the pressure of the water in the outflow hole 52, so that the sealing plug 521 is opened, water flows out of the basin 3 from the water outlet seam on the sealing plug 521, the water addition is completed, and meanwhile, when no water exists in the outflow hole 52, due to the elastic influence of the sealing plug 521, the side walls of the water outlet seam are mutually attached, and the water outlet seam is closed;

because the silica gel layer 57 is arranged on the surface of the extrusion roller 4, and the silica gel layer 57 has elasticity, the discharge slit 571 in the silica gel layer 57 can be extruded by the silica gel layer 57 when no water is discharged, and the discharge slit 571 is closed;

after the buffer cavity 572 is arranged in the silica gel layer 57, the silica gel layer 57 is easier to deform after being pressed, so that when the dough is extruded and kneaded by the extrusion roller 4, a part of deformation can be provided, meanwhile, because the hardness of the silica gel layer 57 is obviously smaller than the strength of the connecting spring 54, the position of the extrusion roller 4 is kept relatively stable by using the connecting spring 54, so that when the dough is extruded and kneaded, the silica gel layer 57 deforms first, then the connecting spring 54 deforms, and the movement of the extrusion roller 4 in the basin 3 is facilitated.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
