Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figure 1-10 , a dough mixer for rice and flour products, including a four-station indexing plate 1, and the four-station indexing plate 1 is sequentially provided with a loading and unloading station 101, a mixing station 102, a dough kneading station 103, and a dough kneading station 104 that are distributed in an annular array.

[0042] It also includes four groups of material buckets 2 that are distributed in an annular array, and the material buckets 2 are assembled on the rotating part of the four-station indexing plate 1 in a detachable manner.

[0043] It also includes three groups of lifting assemblies 3 arranged above the material buckets 2. The lifting assemblies 3 are fixedly installed on the fixed part of the four-station indexing plate 1, and the three groups of lifting assemblies 3 are respectively arranged at the mixing station 102, the dough kneading station 103, and the dough kneading station 104.

[0044] It also includes a mixing component 41, a dough-kneading component 42, and a dough-rubbing component 43 respectively assembled on three groups of lifting components 3; the mixing component 41 includes a mounting shaft 411, a stirring blade 412 and a baffle 413 fixedly connected to the mounting shaft 411, and the baffle 413 is arranged above the stirring blade 412; the dough-kneading component 42 includes an upper mounting plate 421 and a lower mounting plate 422 that maintain a rotating combination, and an outer stirring frame 4211 and an inner stirring frame 4221 fixedly connected to the upper mounting plate 421 and the lower mounting plate 422 respectively, and the outer stirring frame 4211 is arranged outside the inner stirring frame 4221; the dough-rubbing station 104 includes multiple groups of fixed extrusion seats 431, and each group of extrusion seats 431 is arranged in an annular array.

[0045] The four-station indexing disk 1 can drive the four groups of buckets 2 fixedly assembled thereon to circulate reciprocally, so that each bucket 2 can operate in the transfer sequence of the loading / unloading station 101 - the mixing station 102 - the dough-kneading station 103 - the dough-rubbing station 104 - the loading / unloading station 101.

[0046] Taking one group of buckets 2 as an example, the bucket 2 is assembled on the rotating part at the position of the loading / unloading station 101, and an appropriate amount of rice flour, water and other auxiliary materials (such as yeast powder) are added to the bucket 2. Then, the rotating part of the four-station indexing disk 1 is controlled to rotate by a quarter of a circumferential angle to the mixing station 102. At this time, the corresponding lifting component 3 drives the mixing component 41 to descend, so that the mixing component 41 sinks into the bucket 2. The rotating stirring blade 412 can fully mix each raw material, and at the same time, the upper baffle 413 can block the rice flour dust during the mixing process from diffusing outside the bucket 2. After the mixing operation is completed, the lifting component 3 drives the mixing component 41 to rise and reset.

[0047] Continue to control the rotating part to rotate by a quarter of a circumferential angle to the dough-kneading station 103. The corresponding lifting component 3 drives the dough-kneading component 42 to descend, so that the dough-kneading component 42 sinks into the bucket 2. The upper mounting plate 421 and the lower mounting plate 422 maintain reverse rotation to drive the outer stirring frame 4211 and the inner stirring frame 4221 to rotate in reverse respectively, so as to stir and pull the mixed material in the bucket 2 to make the mixed material in a strip shape, meeting the operation requirements of dough-kneading. Then, the lifting component 3 drives the dough-kneading component 42 to rise and reset.

[0048] Continue to control the rotating part to rotate by a quarter of a circumferential angle to the dough-rubbing station 104. The corresponding lifting component 3 drives the dough-rubbing component 43 to descend, so that the dough-rubbing component 43 sinks into the bucket 2. During the continuous operation of each extrusion seat 431, the strip-shaped mixed material is rubbed into a dough shape in cooperation with the bucket 2, thus completing all the dough-kneading operations. Then, the lifting component 3 drives the dough-rubbing component 43 to rise and reset.

[0049] Finally, continue to control the rotating part to rotate by a quarter of a circumferential angle and then run back to the loading and unloading station 101. Remove the dough bucket 2 from the rotating part to await the dough kneading operation for the next batch of rice and flour products.

[0050] To ensure that the four-station indexing plate 1 can achieve its functional design, the following technical solutions are provided.

[0051] The four-station indexing plate 1 includes a support base 11, a mounting column 12, a rotating disk 13, a fixed disk 14, and a motor A 15.

The rotating disk 13, as the rotating part of the four-station indexing plate 1, ensures the stable assembly of the dough bucket 2 on it. The fixed disk 14, as the fixed part of the four-station indexing plate 1, ensures the stable installation of the lifting assembly 3 on it.

[0053] When the motor A 15 drives the driving bevel gear A 151 to operate, it can drive the driving bevel gear A 131 and the rotating disk 13 to operate stably.

[0054] To ensure that the dough bucket 2 can be stably assembled on the rotating disk 13, which is the rotating part, in a detachable manner, the following technical solutions are provided.

[0055] Four groups of positioning disks 132 arranged in a circular array are fixedly connected to the upper surface of the rotating disk 13. A positioning seat 133 is fixedly connected to the center of the positioning disk 132. The bottom of the dough bucket 2 is nested and installed in the positioning disk 132, and a positioning groove 21 that is nested and fitted with the positioning seat 133 is provided at the bottom of the dough bucket 2.

The lifting bracket 32 is slidably installed on the fixed bracket 31 and is arranged through the fixed disk 14. The adjusting lead screw 33 is rotatably installed on the fixed bracket 31 and is threadedly connected to the lifting bracket 32. The motor B 34 is fixedly installed on the fixed bracket 31, and a driving bevel gear B 341 is fixedly connected to the output shaft of the motor B 34. A transmission bevel gear B 331 which meshes with the driving bevel gear B 341 is fixedly connected to the end of the adjusting lead screw 33.

[0059] The setting of the fixed bracket 31 can ensure the stable installation of the lifting bracket 32, the adjusting lead screw 33, and the motor B 34 thereon. The sliding bracket is driven by the rotating adjusting lead screw 33 to stably lift along the fixed bracket 31, thereby adjusting the length of the lifting bracket 32 extending from the lower surface of the fixed disk 14.

[0060] When the motor B 34 drives the driving bevel gear B 341 to operate, it can drive the transmission bevel gear B 331 and the adjusting lead screw 33 to operate, and can drive the lifting bracket 32 to stably lift along the fixed bracket 31.

[0066] When the motor D423 drives the driving bevel gears D4231 and d4232 to operate, it can respectively drive the transmission bevel gears D4213 and d4223 to operate stably. Since the driving bevel gear D4231 and the driving bevel gear d4232 are arranged in a reverse symmetrical manner, the transmission bevel gears D4213 and d4223 can be made to rotate in opposite directions, thereby driving the upper mounting plate 421, the outer stirring frame 4211 and the lower mounting plate 422, the inner stirring frame 4221 to rotate in opposite directions. The dough kneading operation is realized under the reverse rotation of the outer stirring frame 4211 and the inner stirring frame 4221.
