[0042] Mounting seats 8 are arranged on the two sides of the lifting platform 2 opposite to the slide rails 6, and the mounting seats 8 are in right triangle structure, which is beneficial to improve the structural strength of the mounting seats 8;

[0043] Two said mounting seat 8 are arranged in the bottom of the lifting platform 2, the two vertical surfaces of the mounting seat 8, the horizontal surface is connected with the bottom surface of the lifting platform 2, the vertical surface is flush with the side surface of the lifting platform 2, and the vertical surface is connected with the sliding block 7;

[0046] The cooperation of the stabilizing frame 23 and the lifting platform 2 can ensure that the stirring axis of the stirring shaft 3 does not deviate, and the structural stability of the stirring shaft 3 is ensured.

[0047] Further, a plurality of reinforcing ribs are arranged on the bottom surface of the lifting platform 2, the reinforcing ribs are uniformly arranged around the stirring axis of the stirring shaft 3, the structural strength of the lifting platform 2 can be effectively strengthened through the reinforcing ribs, the middle part of the lifting platform 2 is prevented from collapsing after long-term use, and the position accuracy and connection accuracy of each component are ensured.

[0048] The reversing driving device is arranged on the top surface of the lifting platform 2, the reversing driving device comprises a driving motor 15, a first bevel gear 16 and a second bevel gear 17, one end of the stirring shaft located on the upper side of the lifting platform 2 is connected with the first bevel gear 16 and the second bevel gear 17 respectively;

[0049] The output shaft of the driving motor 15 is connected with a driving bevel gear 18, the driving bevel gear 18 is a half gear, the driving bevel gear 18 is located between the first bevel gear 16 and the second bevel gear 17, and is engaged with the first bevel gear 16 and the second bevel gear 17 respectively;

[0050] It should be noted that, based on the structural characteristics that the driving bevel gear 18 has only half of the engaging teeth, the above-mentioned engagement with the first bevel gear 16 and the second bevel gear 17 respectively means that if the driving bevel gear 18 is engaged with the first bevel gear 16, the driving bevel gear 18 is in a separated state with the second bevel gear 17, and vice versa;

[0051] Since the driving bevel gear 18 is arranged between the first bevel gear 16 and the second bevel gear 17, according to the transmission characteristics of the bevel gears, if the driving bevel gear 18 meshes with the first bevel gear 16 and pushes the stirring shaft 3 to rotate in the clockwise direction, when the driving bevel gear 18 re-meshes with the second bevel gear 17, the driving bevel gear 18 will drive the stirring shaft 3 to rotate in the counterclockwise direction, thereby controlling the stirring shaft 3 to turn;

[0052] The bevel gears are designed as half-gears, which cleverly realize the forward rotation and the reverse rotation in one rotation period, thereby controlling the stirring shaft 3 to repeatedly rotate forward and reverse without interruption, and improving the uniformity of stirring through the continuous alternation of the forward rotation and the reverse rotation.

[0053] Further, a hub 19 is arranged on a section of the stirring shaft 3 located at the lower side of the lifting platform 2, a plurality of insertion grooves 20 are arranged on the hub 19 around the axis of the hub 19, one end of each of the adjusting paddles is provided with an insertion head 21, each of the insertion heads 21 is inserted into each of the insertion grooves 20, and a blocking block 22 is further arranged at the inlet end of each of the insertion grooves 20, and the blocking block 22 is fixedly connected with the hub 19 through bolts;

[0055] Through the above structure, the user can conveniently replace stirring paddles of different specifications according to needs, and when a single stirring paddle is damaged, only the specific stirring paddle needs to be replaced, without the need to replace all the stirring paddles, thereby reducing the maintenance cost of the equipment;

[0056] Meanwhile, through the arrangement of the above multi-layer stirring paddles, more turbulent flow can be formed inside the slurry, and since the adjacent two layers of stirring paddles are in an eight-shaped structure, the slurry will collide upward and downward, which is conducive to improving the uniformity of stirring.

[0057] When the slurry preparation device is used, first, the lifting platform is raised by the first driving module to provide space for the installation of the slurry preparation tank, then the slurry preparation tank is placed directly below the lifting platform, the lifting platform is lowered to the specified station by the first driving module, and the stirring shaft enters the slurry preparation tank;

[0058] Subsequently, the stirring shaft is driven to rotate by the reversing driving device, in a rotation cycle, if the stirring shaft rotates in a clockwise direction for a part of time period, the stirring shaft rotates in a counterclockwise direction for another time period, and then the stirring paddle rotates in different rotation directions respectively for one or several times in a cycle;

[0061] Finally, when the rotation direction of the stirring paddle is switched, due to the inertia of the material rotation, the stirring paddle and the material, and the material and the material will collide and fuse violently, which further improves the uniformity of stirring.
