Technical Field

[0001] The utility model relates to the technical field of flour stirring, and particularly relates to a dough mixer. Background Art

[0002] The dough mixer belongs to one kind of pasta machinery. Its main function is to mix flour and water while stirring evenly, and finally ensure that the flour forms a dough. There are vacuum dough mixers and non-vacuum dough mixers on the market, and they can also be divided into various stirring and dough-making methods such as horizontal, vertical, single-axis, double-axis, and semi-axis. However, the existing dough mixers can only perform stirring on a single horizontal plane, or central-axis stirring, or a combination of self-rotation and revolution. Although this kind of dough-making method in the prior art can finally form a dough, there are still problems such as uneven local stirring and incomplete mixing of the upper and lower layers of the dough.

[0003] In view of this, the utility model improves the old stirring method and redesigns the dough stirring structure to solve the urgent problem of multi-level stirring. Content of the Utility Model

[0004] In order to make up for the deficiencies in the prior art and achieve the above functions, the utility model provides a dough mixer.

[0005] The utility model is realized through the following technical solutions:

[0006] A dough mixer includes a rotating box installed directly below a driving box through a driving shaft. A driving motor connected to a speed reducer is arranged in the driving box, and both are fixed in the driving box through connecting plates. A fixed head is installed on the driving shaft extending downward from the speed reducer, and the driving shaft is clamped on a fixed block at the top of the rotating box through the fixed head;

[0007] A double-shaft motor is arranged in the rotating box. The rotating shafts extending left and right from the double-shaft motor are connected to their respective corresponding gear shafts a through couplings on both sides. A bevel gear a is arranged at the other end of the gear shaft a, and the bevel gear a meshes with a vertical bevel gear b. The bevel gear b is fixed on a bearing seat b through a gear shaft b, and the two ends of the gear shaft a are fixed on a lower support plate through bearing seats a;

[0008] A spiral dough stirring rod is arranged below each gear shaft b.

The three double-shaft cylinders are fixed by two front and rear fixing plates a, and the two fixing plates a are connected into a whole through fixing plates b on the left and right sides.

[0010] Further, two vertical slide table modules are respectively arranged on the left and right sides of the fixed plate b, and the fixed plate b is respectively fixed on the sliders of each corresponding slide table module; the slide table modules are fixed on the bottom floor through support rib plates.

[0011] Further, below the spiral and kneading rod is a kneading cylinder and the spiral and kneading rod is located inside the kneading cylinder. A kneading head is arranged at the tail of each spiral and kneading rod. A base for fixing it is arranged below the kneading cylinder, and the base is connected to the floor below through a plurality of damping shock absorbers arranged at the bottom.

[0012] Further, the kneading head is frustum-shaped, and the diameter of its end is larger than the diameter of its head connected to the spiral and kneading rod.

[0013] Further, a controller and a storage battery are arranged inside the rotating box.

[0014] The beneficial effects of the present utility model are as follows:

[0015] For the present utility model, the two spiral and kneading rods rotate in opposite directions. While revolving and rotating on their own axes, they can also move up and down, enabling the materials for kneading to be fully mixed in the horizontal and vertical directions.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but only represents the selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention

[0029] As Figures 1 to 5 shown, the present invention includes a rotary box 1 installed directly below the drive box 2 through a drive shaft 204. A drive motor 201 connected to a reducer 202 is arranged in the drive box 2, and both are fixed in the drive box 2 through a connecting plate 203. A fixed head 205 is installed on the drive shaft 204 extending downward from the reducer 202. The drive shaft 204 is clamped on a fixed block 206 at the top of the rotary box 1 through the fixed head 205. In this way, the drive shaft 204 can drive the entire rotary box 1 to rotate

[0030] A dual-axis motor 101 is arranged inside the rotating box 1. The rotating shafts 102 extending left and right from the dual-axis motor 101 are connected to the respective corresponding gear shafts a105 on both sides through couplings 103 on both sides. A bevel gear a106 is arranged at the other end of the gear shaft a105, and the bevel gear a106 meshes with a vertical bevel gear b107. The bevel gear b107 is fixed on a bearing block b110 through a gear shaft b108. The gear shafts a105 at both ends are fixed on a lower support plate 109 through bearing blocks a104.

[0031] Below each gear shaft b108, there is a spiral dough mixing rod 9 for dough mixing.

[0032] Above the drive box 2, there are three downward dual-axis cylinders 3. The dual-axis cylinders 3 are connected to the drive box 2 through floating joints 301. The three dual-axis cylinders 3 are fixed by two front and rear fixing plates a302. The two fixing plates a302 are connected into a whole through fixing plates b303 on the left and right sides; on the left and right sides of the fixing plate b303, there are respectively two vertical slide table modules 4. The fixing plate b303 is respectively fixed on the sliders of each corresponding slide table module 4. The up and down translation of the dough mixing assembly is controlled through the slide table module 4, so that the dough mixing cylinder 5 can be reasonably placed; the slide table module 4 is fixed on the bottom floor 8 through a support rib plate 401.

[0033] Below the spiral dough mixing rod 9 is the dough mixing cylinder 5 and the spiral dough mixing rod 9 is located inside the dough mixing cylinder 5. At the tail of each spiral dough mixing rod 9, there is a dough mixing head 901. Below the dough mixing cylinder 5, there is a base 6 for fixing it. The base 6 is connected to the lower floor 8 through a plurality of damping shock absorbers 7 arranged at the bottom.

[0034] The dough mixing head 901 is in the shape of a frustum of a cone, and the diameter of its end is larger than the diameter of its head connected to the spiral dough mixing rod 9. The purpose is to gradually widen the gaps of the viscous dough during the dough mixing process, so that the water and flour can come into large-area contact and improve the dough mixing efficiency.

[0035] A controller 111 and a storage battery 112 are arranged inside the rotating box 1 for independent power supply and control.

[0036] Some electrical and pneumatic components in the present utility model need to be connected to related components such as relays, PLCs, electromagnetic pneumatic valves, air pumps, and control panels. The connection methods and the achievable control effects are all prior arts and will not be elaborated here.

[0037] The working principle of the utility model is as follows: (1) Flour, water, and yeast are all added into the dough mixing cylinder 5. Then, the relevant components for dough mixing are controlled by the sliding table module 4 to move upward, and the dough mixing cylinder 5 is placed on the base 6. The relevant components for dough mixing are controlled to move downward to ensure that the spiral dough mixing rod 9 contacts the flour, and then start. (2) After starting the dough mixing, the double-shaft motor 101 indirectly controls the bevel gear b107 to rotate through the bevel gear a106, so that the two spiral dough mixing rods 108 rotate in different directions. At the same time, the driving shaft 204 rotates to control the overall rotation of the entire rotating box 1, that is, the spiral dough mixing rods 108 rotate around their own axes while also revolving around a central axis, ensuring that the flour in a single plane is fully stirred by three rotation methods. (3) At the same time, the three double-shaft cylinders 3 extend and retract, driving the lower rotating box 1 and the driving box 2 to move up and down. That is, the two spiral dough mixing rods 108 that rotate in opposite directions rotate around their own axes and revolve around a central axis while also moving up and down, ensuring the mixing of water, yeast, and flour at different height layers. (4) After the dough is kneaded into a mass, the operations described in step (3) all stop. The sliding table module 4 controls the relevant components for dough mixing to move upward, and then the dough is taken out of the dough mixing cylinder 5.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention shall be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
