Flour and water are added to the steel bowl in a specific ratio, and a motor drives the mixing blade to rotate, thoroughly mixing the water and flour. However, in actual use, there are some functional shortcomings that allow for improvement. For example, the height of the blade is fixed, and because the blade extends into the steel bowl, removing the dough and cleaning the bowl is cumbersome and requires disassembly. Furthermore, since the arm extends into the steel bowl and is in the same space as the blade, there is a certain safety risk, and the machine lacks a function to lift the blade to improve safety.

[0004] Now, a new type of dough mixer for bread production is proposed to solve the above problems. Utility Model Content

[0007] The lifting assembly includes two sets of limiting guide tubes, which are fixedly connected to the two sides of the top of the fixed housing. Two sets of limiting guide rods are vertically fixedly connected to the right side of the bottom of the top housing. Limit switches are installed at the bottom of both sides of the fixed housing. An electric cylinder is installed at the middle position of the bottom of the bottom of the bottom housing.

[0008] As a further technical solution of this utility model, the fixed box and the top box are not connected, and the limiting guide rod passes through the top of the fixed box and extends into the interior of the limiting guide tube.

[0009] As a further technical solution of this utility model, the outer diameter of the limiting guide rod is the same as the inner diameter of the limiting conduit. The limiting guide rod passes through the bottom box and extends into the interior of the limiting conduit. The limiting guide rod can slide up and down along the interior of the limiting conduit.

[0010] As a further technical solution of this utility model, the output end of the electric cylinder is connected to the bottom end of the top box, and the control box, the geared motor, the limit switch and the electric cylinder are electrically connected.

[0013] As a further technical solution of this utility model, a protective shell is fixedly connected to the right side of the fixed box, a water guide pipe is fixedly connected inside the protective shell, a flow sensor is installed on the left side of the protective shell, a solenoid valve is fixedly connected to the right side inside the protective shell, and a water outlet is fixedly connected to the bottom end of the solenoid valve.

[0014] As a further technical solution of this utility model, the water guide pipe, the solenoid valve, and the water outlet are internally connected, and the control box, the flow sensor, and the solenoid valve are electrically connected.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the dough mixer for bread production not only realizes the function of raising the blade head to improve safety, but also realizes the function of easy disassembly of the drive steel bowl, and also realizes the function of easy quantitative water addition;

[0016] (1) By setting up a top box, pressing rod, reduction motor and dough mixing head, limiting guide rod, limiting guide tube, limit switch and electric cylinder, when in use, flour and water are added into the first steel bowl in proportion. The reduction motor drives the dough mixing head to rotate continuously, and the flour and water are fully mixed to form dough. When it is necessary to take out the dough or clean the steel bowl, the electric cylinder is activated to extend it upward. The electric cylinder pushes the top box to move upward. The limiting guide rod and the limiting guide tube can make it rise smoothly. As the limiting guide rod moves upward, the limit switch loses the pressure of the limiting guide rod and resets upward. The power supply of the reduction motor is then disconnected, and the dough mixing head will not rotate. It is safer to take out the dough and clean the steel bowl. At the same time, it is convenient to replace the steel bowl. It realizes the function of raising the head to improve safety.

[0017] (2) By setting up a drive motor, reducer, drive shaft, spline groove, limit ring and spline head, when in use, as the top box moves up, the pressing rod no longer presses on the steel bowl, and the steel bowl can be directly removed from the top of the drive shaft. Two sets of steel bowls can be used alternately, one set for mixing and the other for kneading, making the operation more efficient. When kneading, the top box is pressed down, and the pressing rod is pressed on the bottom of the steel bowl to prevent it from loosening during rotation. The drive motor drives the drive shaft to rotate continuously through the reducer. The drive shaft and the steel bowl are connected by the spline groove, limit ring and spline head, and the steel bowl can rotate continuously to promote kneading. This realizes the function of easy disassembly of the drive steel bowl.

[0018] (3) By setting up a protective shell, water pipe, flow sensor, solenoid valve and water outlet, when in use, the first steel bowl weighs the new flour and adds it into the second steel bowl during the dough kneading process. The pure water pipe is connected to the water inlet at the bottom of the water pipe and the corresponding faucet is turned on. The flow sensor monitors the water inlet. After the water inlet reaches the standard, the solenoid valve closes and the water outlet stops discharging water, thus realizing the function of convenient quantitative water addition.

[0026] Example: Please refer to Figure 1-5 A dough mixer for bread production includes a bottom box 1, a fixed box 2 fixedly connected to the middle of the top of the bottom box 1, a control box 3 fixedly connected to the front end of the fixed box 2, a first steel bowl 4 horizontally placed on the left side of the top of the bottom box 1, a second steel bowl 24 horizontally placed on the right side of the top of the bottom box 1, handles 25 movably connected to the front and rear ends of the first steel bowl 4 and the second steel bowl 24 respectively, a top box 5 is provided at the top of the fixed box 2, a pressing rod 6 is fixedly connected to the left side of the bottom of the top box 5, a reduction motor 7 is installed at the bottom of the top box 5, a dough mixing blade 8 is fixedly connected to the output end of the reduction motor 7, and a lifting component that can be adjusted for safety is provided inside the fixed box 2.

[0027] Please see Figure 1-5 A dough mixer for bread making also includes a lifting component, which includes two sets of limiting guide tubes 10. The two sets of limiting guide tubes 10 are respectively fixedly connected to the two sides of the top of the fixed box 2. Two sets of limiting guide rods 9 are vertically fixedly connected to the right side of the bottom of the top box 5. Limit switches 11 are respectively installed at the bottom of the two sides inside the fixed box 2. An electric cylinder 12 is installed at the middle position of the bottom end inside the bottom box 1.

[0028] The fixed housing 2 and the top housing 5 are not connected. The limiting guide rod 9 passes through the top of the fixed housing 2 and extends into the interior of the limiting guide tube 10. The outer diameter of the limiting guide rod 9 is the same as the inner diameter of the limiting guide tube 10. The limiting guide rod 9 passes through the bottom housing 1 and extends into the interior of the limiting guide tube 10. The limiting guide rod 9 can slide up and down along the interior of the limiting guide tube 10. The output end of the electric cylinder 12 is connected to the bottom end of the top housing 5. The control box 3, the reduction motor 7, the limit switch 11, and the electric cylinder 12 are electrically connected, which improves safety and facilitates operation.

[0029] Specifically, such as Figure 1 and Figure 2 As shown, the electric cylinder 12 is activated to extend upwards, pushing the top housing 5 upwards. The limiting guide rod 9 and the limiting guide tube 10 allow it to rise smoothly. As the limiting guide rod 9 moves upwards, the limit switch 11 loses the pressure of the limiting guide rod 9 and resets upwards, thus disconnecting the power supply to the geared motor 7. The dough mixing blade 8 will not rotate, making it safer to remove dough and clean the steel bowl, and also facilitating the replacement of the steel bowl. The control box 3, geared motor 7, limit switch 11, and electric cylinder 12 are electrically connected. This technology is existing technology and will not be described in detail.

[0030] A reducer 14 is fixedly connected to the left side of the bottom of the bottom housing 1. A drive motor 13 is installed on the top of the reducer 14. A drive shaft 15 is vertically movably connected to the left side of the top of the bottom housing 1. A spline groove 16 is opened on the top of the drive shaft 15. A limit ring 17 is fixedly connected to the outer ring of the bottom of the first steel bowl 4 and the second steel bowl 24. A spline head 18 is fixedly connected to the middle position of the bottom of the first steel bowl 4 and the second steel bowl 24. The external shape and size of the spline head 18 are adapted to the internal shape and size of the spline groove 16. The inner diameter of the limit ring 17 is the same as the outer diameter of the drive shaft 15. The bottom of the drive shaft 15 is connected to the output end of the reducer 14. The control box 3 and the drive motor 13 are electrically connected, which facilitates the disassembly and driving of the steel bowls.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the two sets of steel bowls can be used alternately, one for mixing and the other for kneading, making the operation more efficient. When kneading, the top box 5 presses down, and the pressing rod 6 presses against the bottom of the steel bowl to prevent it from loosening during rotation. The drive motor 13 drives the drive shaft 15 to rotate continuously through the reducer 14. The drive shaft 15 and the steel bowl are engaged and transmitted through the spline groove 16, the limit ring 17 and the spline head 18. The steel bowl can rotate continuously, promoting kneading. The control box 3 and the drive motor 13 are electrically connected. This technology is existing technology and will not be described in detail.

[0032] A protective housing 19 is fixedly connected to the right side of the fixed housing 2. A water guide pipe 20 is fixedly connected inside the protective housing 19. A flow sensor 21 is installed on the left side of the protective housing 19. A solenoid valve 22 is fixedly connected to the right side inside the protective housing 19. A water outlet 23 is fixedly connected to the bottom end of the solenoid valve 22. The water guide pipe 20, the solenoid valve 22, and the water outlet 23 are internally connected. The control box 3, the flow sensor 21, and the solenoid valve 22 are electrically connected to facilitate quantitative water addition.

[0033] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, during the dough kneading process, the first steel bowl 4 weighs the new flour and adds it to the second steel bowl 24. The purified water pipe is connected to the water inlet at the bottom of the water pipe 20 and the corresponding faucet is turned on. The flow sensor 21 monitors the water inflow. After the water inflow reaches the target, the solenoid valve 22 closes and the water outlet 23 stops discharging water. The control box 3, the flow sensor 21, and the solenoid valve 22 are electrically connected. This technology is existing technology and will not be described in detail.

[0034] Working principle: When using this utility model, firstly, flour and water are added into the first steel bowl 4 in proportion. The reduction motor 7 drives the dough mixing head 8 to rotate continuously, fully mixing the flour and water to form dough. When it is necessary to remove the dough or clean the steel bowl, the electric cylinder 12 is activated to extend it upward. The electric cylinder 12 pushes the top box 5 upward. The limit guide rod 9 and the limit guide tube 10 can make it rise smoothly. As the limit guide rod 9 moves upward, the limit switch 11 loses the pressure of the limit guide rod 9 and resets upward. The power supply of the reduction motor 7 is then disconnected, and the dough mixing head 8 will not rotate. This makes it safer to remove the dough and clean the steel bowl, and also makes it easier to replace the steel bowl. As the top box 5 moves upward, the pressing rod 6 no longer presses against the steel bowl, allowing the steel bowl to detach directly from the top of the drive shaft 15. The two sets of steel bowls can be used alternately, one for mixing and the other for kneading, making the operation more efficient. During kneading, the top box 5 presses down, and the pressing rod 6 presses against the bottom of the steel bowl to prevent loosening during rotation. The drive motor 13 drives the drive shaft 15 to rotate continuously through the reducer 14. The drive shaft 15 and the steel bowl are engaged and transmitted through the spline groove 16, the limit ring 17, and the spline head 18, allowing the steel bowl to rotate continuously and promoting kneading. During the kneading process, new flour is weighed and added to the second steel bowl 24 in the first steel bowl 4. The purified water pipe is connected to the inlet at the bottom of the water pipe 20, and the corresponding faucet is turned on. The flow sensor 21 monitors the water inflow. Once the water inflow reaches the target, the solenoid valve 22 closes, and the outlet 23 stops dispensing water.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
