Description

Technical Field

[0001] The utility model mainly relates to the technical field related to dough mixers, in particular to a low-noise dough mixer. Background Art

[0002] Dough mixers are mainly used to replace manual dough kneading and are widely used in the catering industry. The basic principle is to drive the stirring shaft in the hopper to stir the flour to complete the dough kneading.

[0003] In the prior art, the driving structure of the dough mixer is generally located on one side of the hopper and drives the stirring shaft to rotate through a primary or multi-stage sprocket drive. In this structural design, if the dough mixing amount is 25 kg / time, the overall height of the equipment needs to be relatively high. For some specific places, if the overall height of the dough mixer is required to be as small as possible so that the dough mixer can be stored under the table, the traditional structural design is difficult to meet the height requirement. In addition, the dough mixer shakes a lot during the dough mixing process. When the weight is not reasonable, the shaking amplitude is large and the noise is large.

[0004] In the existing dough mixer structure, most hoppers adopt a flip-type structure design to facilitate the loading and unloading of noodles. The flip connection is mostly directly connected by bearings, which is inconvenient to disassemble and assemble, and the sealing is not good. After a period of use, black noodles are easily squeezed out. In addition, due to the design of the flip structure, if the hopper is not locked firmly, the hopper part is prone to shaking greatly during operation, and the stability is poor.

[0036] The dough mixer of this embodiment mainly includes a frame 1, a driving mechanism, a hopper 2, and a stirring shaft 11 arranged in the hopper 2, and a stirring blade (not shown in the figure) is installed on the stirring shaft 11. The driving mechanism of the dough mixer includes a reduction motor 4, a transmission shaft 5, a double-row driving sprocket 7, and a double-row driven sprocket 8; wherein the reduction motor 4 is installed at the lower part of one side of the hopper 2, the transmission shaft 5 is arranged below the hopper 2, one end of which is connected to the reduction motor 4, and the other end is installed with a driving sprocket 7 and supported by a universal bearing 6, the driven sprocket 8 is located on the other side of the hopper 2 and is installed on the stirring shaft 11, and the driving sprocket 7 and the driven sprocket 8 are connected by a chain.

[0037] In the above structure of this embodiment, the movement of the reduction motor 4 drives the transmission shaft 5 to rotate, and the transmission shaft 5 transmits power to the stirring shaft 11 through the sprocket, thereby driving the stirring shaft 11 to work. The reduction motor 4 adopts an RV worm gear reduction motor, and the aluminum shell body is easy to dissipate heat. The power speed ratio can be configured separately according to work requirements. It has strong power, simple replacement, and easy after-sales maintenance. The worm gear reducer is equipped with a first-level double chain drive, which has low noise and sufficient power. The reduction motor 4 is set on both sides of the sprocket and the transmission shaft 5 is placed at the bottom, so that the lower counterweight of the dough mixer is large, which ensures its stability during operation.

[0038] In this embodiment, the universal bearing 6 and the reduction motor 4 are both mounted on the frame 1, and their positions in the up and down directions can be adjusted through the long holes provided on the frame 1, which facilitates the debugging and subsequent maintenance of the equipment.

[0039] In this embodiment, the hopper 2 adopts a flippable structure design, that is, the hopper 2 can be flipped alone to facilitate loading and unloading, and the flipping action of the hopper 2 is achieved by the rotating support members 12 on both sides. In this embodiment, the rotating support members 12 are used to provide support for the stirring shaft 11 on the one hand, and can support the hopper 2 on the other hand without affecting the normal flipping of the hopper 2.

[0040] refer to Figure 5-Figure 7As shown, in this embodiment, the rotating support member includes a fixed tile seat 13 and a rotating tile seat 14, the fixed tile seat 13 includes a fixed tile seat fixing end 16 and a fixed tile seat connecting end 18, the fixed tile seat fixing end 16 has a connecting hole for mounting on the side plate of the frame, the rotating tile seat 14 includes a rotating tile seat fixing end 19 and a rotating tile seat connecting end 20, the rotating tile seat fixing end 19 has a connecting hole for mounting on the side plate of the hopper 2, the rotating tile seat connecting end 20 is rotatably matched with the fixed tile seat connecting end 18, and through holes are set in the center of the fixed tile seat 13 and the rotating tile seat 14 for connecting the stirring shaft 11. Through the above structure, the hopper 2 can be turned over. In order to facilitate the disassembly and assembly of the hopper, in the present embodiment, an arc groove 17 is arranged on the circumference of the outer circle of the fixed tile seat connection end 18, and three mounting holes are arranged on the rotating tile seat connection end 20.
