And then the cylinder cover 2 is covered, the stirring piece is placed in the mixing tank and is contacted with the raw materials, the motor drives the stirring piece positioned at the side of the main shaft 21 to rotate in the mixing tank, and the raw materials are mixed and stirred by the stirring piece. Specifically, the stirring piece is a plurality of hollow tubes 24, the plurality of hollow tubes 24 are equally divided into a plurality of groups, the plurality of groups of hollow tubes 24 are equidistantly arranged on the side of the main shaft 21, a first connecting block is fixed between the plurality of hollow tubes 24 of the same group, a second connecting block is fixed between one hollow tube 24 on the side of the most side and the side wall of the end part of the main shaft 21, the hollow tubes 24 are distributed in the mode shown in fig. 2, when the main shaft 21 rotates, all the hollow tubes 24 can be driven to rotate towards the same direction, and the upper end opening and the lower end opening of the hollow tube 24 shown in fig. 2 are horizontally arranged, so that the hollow tubes 24 take the main shaft 21 as the center to do circular motion stirring track, and the raw materials mixed together can be stirred by the walls of the hollow tubes 24 to move in the mixing groove to speed up the full mixing progress. In addition, part of raw materials can enter into the hollow tube 24 through the opening of hollow tube 24 one end, and along with the rotation centrifugal force of hollow tube 24 makes the raw materials that enter into the hollow tube 24 throw away from the other end, and the raw materials after the hollow tube 24 compares the position before entering into hollow tube 24 and can appear changing in a large extent, through constantly rotating hollow tube 24, when part of raw materials is stirred by hollow tube 24, still have part of raw materials to pass through hollow tube 24 direct change position, and the two modes mutually support, can improve the speed of mixing. The embodiment describes one of the links in the whole production process of the environment-friendly tableware, namely, the mixing of the raw materials before fermentation is carried out, so as to improve the quality of the final product. The stirring piece is utilized to fully stir the raw materials in the mixing tank, so that the problem that the produced environment-friendly tableware is uneven in texture and the strength and durability are affected due to insufficient stirring and even fermentation of the raw materials is solved. Even the produced environment-friendly tableware has the defects of bubbles and the like, influences the appearance and quality of the tableware, and has the problems of reworking or scrapping, increased production cost and resource waste
The first stirring mode is that the opening at the upper end of the hollow tube 24 faces the tangential direction of the rotation direction of the main shaft 21, the opening at the lower end of the hollow tube 24 faces the tangential direction of the rotation reverse direction of the main shaft 21, the motor can adopt a servo motor to drive the main shaft 21 to rotate clockwise, as shown in fig. 2, the hollow tube 24 rotates clockwise along with the main shaft 21, raw materials can enter the hollow tube 24 from the opening at the upper end of the hollow tube 24, the raw materials can be thrown out from the opening at the bottom of the hollow tube 24 under the influence of the rotation centrifugal force of the hollow tube 24, and in the process, the raw materials above the mixing tank can be quickly replaced to the lower position in the mixing tank through the hollow tube 24, so that the process of mixing the raw materials from top to bottom in the mixing tank is realized, the process is repeated continuously, and the mixing efficiency of the raw materials can be accelerated.
The second stirring mode is that the upper end opening of the hollow tube 24 faces the tangential direction of the rotation direction of the main shaft 21, the lower end opening of the hollow tube 24 faces the tangential direction of the rotation direction of the main shaft 21, as shown in fig. 2, the hollow tube 24 rotates anticlockwise along with the main shaft 21, raw materials enter the hollow tube 24 from the lower end opening of the hollow tube 24, and the raw materials are thrown out from the upper opening of the hollow tube 24 under the influence of the rotation centrifugal force of the hollow tube 24.
Further with the upper end opening of hollow tube 24 for the setting of a font structure, structure as shown in fig. 3, the raw materials receives hollow tube 24 and rotates centrifugal force influence and can throw away from hollow tube 24 upper portion opening, can throw away from a font structure opening, can enlarge the scope when raw materials throws away like this, avoids the raw materials to concentrate to pile up for mixing. This improvement is only applicable to the second stirring mode, i.e. the material is thrown out of the upper opening of the hollow tube 24 only during the counter-clockwise rotation of the hollow tube 24. This, if applicable to the first mode of agitation, affects the rate at which the material enters the hollow tube 24.
In addition, a plurality of material distribution openings 25 are formed in the side wall of the hollow tube 24 so as to be aligned with the opening at the upper end of the hollow tube 24, as shown in fig. 4 and 5. In the process that the raw materials are influenced by the rotation centrifugal force of the hollow pipe 24 and can be thrown out from the upper opening or the lower opening of the hollow pipe 24, part of the raw materials can be separated through the plurality of material separating openings 25, so that the raw materials are guided out to the middle position of the mixing tank in the middle process in the process of the mixing operation of the position of the raw materials from top to bottom or the position of the raw materials from bottom to top, and the mixing efficiency is further improved. The present mode is applicable to the first stirring mode and the second stirring mode.
Further, a boom 26 is fixed to the bottom wall of the main shaft 21, at least two shovel plates 27 are provided on the side of the boom 26, and the bottom wall of the shovel plates 27 is rotationally attached to the bottom wall of the mixing tank. As shown in fig. 6. When the main shaft 21 rotates, the stirring member rotates in the mixing tank to perform a rotational mixing operation on the raw materials, and the shovel 27 on the side of the boom 26 is driven to rotate in the mixing tank. When rotating, the shovel 27 is used for shoveling the raw materials at the bottom in the mixing tank, and the shoveled raw materials can be fully stirred by the stirring piece, so that the shovel 27 is used for carrying out full mixing operation on the raw materials better, faster and more uniformly by matching with the stirring piece.
As shown in fig. 7. The side walls on two sides of the shovel plate 27 are obliquely bent towards the upper side of one side, which is close to each other, of the shovel plate 27, the bottom wall of the shovel plate 27 is an upward bulge bending part, the edge of the bottom of the side wall, which is consistent with the rotation direction, of the shovel plate 27 can directly shovel the raw materials at the bottom in the mixing tank in the rotation process of the main shaft 21, the shoveled raw materials creep in a manner shown by an arrow in fig. 6, and the raw materials at the bottom in the mixing tank can be quickly shoveled away from the bottom wall in the moment and then are fused into the raw materials at the upper part, so that the mixing efficiency is accelerated. In addition, the bottom wall of the shovel 27 is provided with an upward bulge bending part, so that the contact surface between the bottom wall of the shovel 27 and the bottom wall of the mixing tank is reduced, the friction force between the shovel 27 and the bottom wall of the mixing tank when the shovel 27 rotates to shovel up raw materials is reduced, namely the rotation resistance is reduced, and meanwhile scraping noise is avoided.
In addition to the above-described scooping method, the scooping method of fig. 8 and 9 may be adopted, that is, the side walls of the two sides of the scooping plate 27 are inclined and curved downward toward the side close to each other, and the bottom of the scooping plate 27 has a straight structure. When the shovel 27 rotates, the side wall on one side, which is the same as the rotation direction of the main shaft 21, can be used for pushing the raw materials at the bottom of the mixing tank to do circular motion, and the pushed raw materials are free in position, and the raw materials at the upper part of the mixing tank sink down to supplement the free space, so that in the process, the raw materials pushed by the side wall of the shovel 27 can turn over on the inclined plane of the inclined bending of the shovel 27, as shown by an arrow in fig. 8, and the raw material mixing efficiency is improved.
The two modes of scooping up the raw materials by the scooping plate 27 to accelerate the mixing efficiency are also applicable to the first stirring mode and the second stirring mode.
In addition, the two sides of the mixing drum 1 are rotatably provided with the supporting frames 12, two cross beams 13 which are parallel to each other are fixed between the two supporting frames 12, the two cross beams 13 and the two supporting frames 12 form a supporting frame which rotatably supports the mixing drum 1, after the raw materials are fully mixed, the mixing drum 1 can be turned around the rotating position of the mixing drum 1 and the rotating position of the mixing drum 12 until the opening is slightly inclined downwards, and the raw materials are guided out along the inclined side walls, so that the raw materials are dumped. However, this mode is required to be completed by manpower, and is difficult to be operated by a single person, so by fixing a threaded sleeve 14 at the upper end of one of the cross beams 13, the threaded sleeve 14 is in threaded connection with an adjusting rod 17, the end of the adjusting rod 17 extends to the other cross beam 13 from below the mixing drum 1, and is in rotary connection with a push plate 15, a rectangular guide rod 16 is fixed between the two cross beams 13, the push plate 15 is in sliding sleeve connection with the rectangular guide rod 16, the push plate 15 is positioned at the side of the mixing drum 1, and the upper end of the push plate 15 is bent towards the upper side far from the mixing drum 1, as shown in fig. 10.
