Abstract
Description
Technical Field
[0001] This utility model relates to the field of dough mixing equipment technology, and more specifically, it relates to a three-arm dough mixer. Background Technology
[0002] A dough mixer is a type of pasta machinery, primarily used to evenly mix flour and water. There are vacuum dough mixers and non-vacuum dough mixers. They are categorized as horizontal, vertical, single-shaft, double-shaft, and half-shaft types. The spiral stirring hook is driven by a transmission device to rotate within the mixing tank, which in turn rotates at a constant speed. Inside the tank, the flour is continuously pushed, pulled, kneaded, and pressed, thoroughly mixing and rapidly blending it. This ensures the dry flour is evenly hydrated, developing gluten and forming a dough with elasticity, stretchability, and uniform flowability.
[0003] Most existing dough mixers have a single mixing shaft or a mixing shaft setup, resulting in low efficiency during dough mixing. Furthermore, when removing the dough, it is necessary to stop the mixing blades and then use hands or tools to remove the dough from the bottom of the bowl from the top, a process that takes a long time and is quite laborious. Therefore, we propose a three-arm dough mixer. Utility Model Content

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0022] like Figure 1 As shown, this utility model provides a three-arm dough mixer, including: a frame 1; a dough mixing drum 2 rotatably mounted on the frame 1; a discharge hole 3 at the bottom of the dough mixing drum 2; a mounting base 4 hinged to the top of the frame 1; three mixing arms 5 for stirring the flour in the dough mixing drum 2 and a first drive module 6 for driving the three mixing arms 5 to rotate synchronously on the mounting base 4; a discharge module 7 for movably sealing the discharge hole 3, a second drive module 8 for driving the dough mixing drum 2 to rotate, and a control module are also provided on the frame 1; the control module is electrically connected to the first drive module 6, the second drive module 8, and the discharge module 7 respectively.
[0023] In this embodiment, as Figure 1-5As shown, the control module (not shown in the attached figure) is installed on the frame 1. It includes a controller, an electrical control cabinet, and a power switch. The electrical control cabinet contains a complete control circuit. The controller can be a microcontroller, MCU, PLC, or other controller capable of controlling the orderly operation of various electrical components. In this embodiment, an MCU is selected. The dough kneading process is as follows: Press the power switch of the control module (not shown in the attached figure) on the frame 1. The dough kneader is in standby mode, and the discharge assembly is sealed to the discharge hole 3. Lift the front end of the mounting base 4 upwards, add flour and water to the kneading bucket 2, and then lower the three stirring arms 5. Next, press the dough kneading button on the frame 1. The controller controls the operation of the mixing components, pushing, pulling, kneading, and pressing the flour and water. After the predetermined kneading time is reached, the controller controls the discharge component to stop sealing with the discharge hole 3. With the continued mixing of the three mixing arms 5, the kneaded dough falls from the discharge hole 3 into the receiving container and is transported by the conveyor belt to the next process. The overall structure is stable and easy to install. After the dough is kneaded, there is no need to stop or lift the mixing arms 5, and there is no need to remove the dough from the kneading bucket 2 by hand or with tools. Instead, the dough can be removed by continuing to use the mixing components, which has the advantages of safety, labor saving and high efficiency.
[0024] Furthermore, a support plate 9 is provided on the mounting base 4; the three stirring arms 5 are arranged in a triangular structure and can be rotatably mounted on the support plate 9, and their input ends are connected to the first drive module 6 for transmission; specifically, the three stirring arms 5 are all spiral stirring arms 5, and the three stirring arms 5 are arranged in a triangular distribution, which makes the dough more uniform and improves the dough kneading efficiency.
[0025] Further, the first drive module 6 includes: a first motor 61, a reducer 62, a transmission belt (not shown in the figure), a toothed synchronous pulley 63, and three first transmission gears 64 adapted to the synchronous pulley; the reducer 62 is installed inside the mounting base 4; the first motor 61 is fixedly connected to the mounting base 4, and its output end passes through the side wall of the mounting base 4 and is connected to the input end of the reducer 62; the input ends of the three stirring arms 5 pass through the side wall of the mounting base 4 and are placed inside the mounting base 4, and are respectively fixedly connected to the three first transmission gears 64 one-to-one; the toothed synchronous pulley 63 is rotatably installed inside the mounting base 4, and its output end is connected to the three first transmission gears 64 respectively; the output end of the reducer 62 is connected to the input end of the toothed synchronous pulley 63 through the transmission belt (not shown in the figure); the reducer 62 is electrically connected to the control module (not shown in the figure).
[0026] In this embodiment, as Figure 1-2As shown, the toothed synchronous pulley 63 is a mature technology product on the market and belongs to existing technology, so it will not be described in detail here. During operation, the first motor 61 drives the transmission belt through the reducer 62, and drives the toothed synchronous pulley 63 to rotate through the transmission belt (not shown in the attached figure). During the rotation of the toothed synchronous pulley 63, it synchronously drives the three transmission gears to rotate, which in turn drives the three mixing arms 5 to rotate, so as to realize the dough kneading action.
[0027] Furthermore, the support plate 9 is provided with a dust cover 13 for covering the dough mixing bucket 2; the dust cover 13 is provided with an observation port 10 and a feeding hole 11; specifically, the dust cover 13 is provided so that flour can be scattered everywhere during the mixing process, and the observation port 10 and the feeding hole are provided so as to observe the dough mixing situation in the dough mixing bucket 2 and add flour or water.
[0028] Furthermore, the second drive module 8 includes: two second motors 81 and two second transmission gears 82; the dough mixing drum 2 is rotatably mounted on the frame 1; the bottom of the dough mixing drum 2 is provided with a transmission disc of an annular structure; the outer side of the transmission disc 12 is provided with teeth that are adapted to the second transmission gears 82; both second motors 81 are mounted on the frame 1, and their output ends are respectively connected to the two transmission gears in a one-to-one transmission connection; the two transmission gears are respectively meshed with the transmission disc 12.
[0029] In this embodiment, as Figure 1-4 As shown, two motors are arranged side by side on the frame 1, and two second transmission gears 82 are respectively installed at the output ends of the two second motors 81. When working, the two second motors 81 work synchronously in the forward or reverse direction, thereby driving the dough mixing bowl 2 to rotate in the forward or reverse direction, so as to cooperate with the mixing arm 5 to perform the dough mixing action.
[0030] Furthermore, the discharge module 7 includes: an electric telescopic rod 71; an electric cylinder 72 is provided on the electric telescopic rod 71; a sealing cover 73 is provided on the movable end of the electric cylinder 72; the electric telescopic rod 71 is fixedly connected to the frame 1; the sealing cover 73 is movably and sealingly connected to the discharge hole 3; the electric telescopic rod 71 and the electric cylinder 72 are both electrically connected to the control module (not shown in the figure).
[0031] In this embodiment, as Figure 1-5As shown, one end of the electric telescopic rod 71 is fixed inside the frame 1, and the other end is equipped with an electric cylinder 72. During discharge, the controller first controls the second motor 81 to stop rotating, and then controls the movable end of the electric cylinder 72 to move downward, so that the sealing cover 73 moves downward away from the discharge hole 3. Then, the controller continues to control the electric telescopic rod 71 to retract into the frame 1, so that the sealing cover 73 moves away from the discharge hole 3 in the horizontal direction. Then, the controller controls the second motor 81 to rotate again, and the dough falls from the discharge hole 3 into the receiving container under the action of the stirring paddle. The electric telescopic rod 71 can also be replaced by a slide table combined with a cylinder or hydraulic cylinder. The electric cylinder 72 can also be replaced by a telescopic power device such as a cylinder or hydraulic cylinder. In this embodiment, the electric telescopic rod 71 and the electric cylinder 72 can realize the automatic opening of the sealing cover 73 of the dough mixer without manual intervention, which is labor-saving and efficient.
