The working principle of the embodiment is as follows: during the centrifugal drying process of the material, when the rotating speed of the rotating component 4 is lower than a threshold value r 0 When the elastic force of the first elastic member 7.6 acts downwards on the sliding member 7.4, the abutting groove 7.41 of the sliding member 7.4 abuts against the third roller 7.15 at the end part of the rotating rod 7.2, the rotating rod 7.2 is in a horizontal state under the limit of the limiting block 7.13, the movable basket 7.1 is in the first station, the movable basket 7.1 is kept right, the centrifugal force generated by the heavy ball 7.10 acts on the trigger member 7.9 along the direction of the guide groove 7.17 in the rotating process of the rotating assembly 4, the extrusion force of the heavy ball 7.10 on the trigger member 7.9 is insufficient to overcome the principle of the main acting force at the moment (only the principle is illustrated, and small acting forces such as friction force among a plurality of corresponding parts or centrifugal force of other parts are ignored in the process, but the working principle of the embodiment is not hindered, namely, the rotating wheel 7.7 is only abutted against the arc-shaped surface 7.42; when the rotational speed of the rotating assembly 4 reaches or even exceeds the threshold r 0 When the centrifugal force applied to the heavy ball 7.10 is obviously increased, the acting force of the heavy ball 7.10 on the trigger piece 7.9 is increased, the elastic force of the first elastic piece 7.6 and the elastic force of the second elastic piece 7.8 are overcome, the trigger piece 7.9 and the rotating wheel 7.7 are driven to move along the direction of the guide groove 7.17, the rotating wheel 7.7 rolls over the arc-shaped surface 7.42 to reach the horizontal surface 7.43, the sliding piece 7.4 moves upwards, the sliding piece 7.4 pulls the third rolling wheel 7.15 upwards through the abutting groove 7.41, the rotating rod 7.2 rotates, once the horizontal posture of the rotating rod 7.2 is lost, the centrifugal force of the movable basket 7.1 and materials in the movable basket 7.1 rotates to the second station, the movable basket 7.1 and the materials are adjusted to the inclined postures, and the material spin-drying effect can be promoted; at this time, the rotation speed of the rotating assembly 4 is reduced until the weight balls 7.10 are alignedWhen the acting force of the trigger piece 7.9 is smaller than the elastic force of the second elastic piece 7.8 (and the friction resistance between corresponding moving parts but does not contain the elastic force of the first elastic piece 7.6), the elastic force of the second elastic piece 7.8 pushes the rotating wheel 7.7 away from the state of being in contact with the horizontal plane 7.43, after the sliding piece 7.4 loses the contact of the rotating wheel 7.7 to the horizontal plane 7.43, the elastic force of the first elastic piece 7.6 immediately moves the sliding piece 7.4 downwards, the sliding piece 7.4 rotates the rotating rod 7.2 through the contact groove 7.41, the rotating rod 7.2 overcomes the pressure of the movable frame to enable the movable basket 7.1 to rotate and reset to the first station, and the rotating speed r of the rotating assembly 4 at the moment 1 Less than the threshold.
The beneficial effects of this embodiment are: firstly, compared with the prior art, in the centrifugation process, the movable basket 7.1 and the materials can be subjected to centrifugal spin-drying under the conditions of respectively maintaining two different postures and transition states between the two postures, so that the situation that centrifugal moisture in the single-posture materials is blocked by the impermeable part of the materials and cannot be separated from the materials can be effectively relieved, the postures of the materials are changed in the centrifugation process, the angle is adjusted, the moisture is easily thrown out, a better spin-drying effect can be achieved on the materials, and the spin-drying and dehydration of the materials are more complete; the change of the centrifugal posture of the material is realized in the centrifugal process by the centrifugal force generated by the rotation of the rotating component 4 through the passive posture adjusting mechanism 7, a power system is not required to be additionally arranged, and the driving component and the rotating component 4 are not required to be stopped during posture adjustment. Secondly, the rotation driving assembly 4 is required to rotate, the servo motor is easily overloaded and damaged due to long-time high-power output, and the design of the passive attitude adjusting mechanism 7 in the embodiment has the other advantage that the rotation assembly 4 is lifted from starting to keeping close to the threshold r 0 In the rotating process of the rotating speed of the movable basket 7.1, the movable basket 7.1 is always kept at the first station, the material in the movable basket 7.1 is in a right posture for centrifugal drying, the rotating assembly 4 and the driving assembly can safely and stably maintain the rotating speed for a long time, and when the material drying effect needs to be further improved after a period of operation, the rotating speed of the rotating assembly 4 is only required to be briefly improved to a threshold value r 0 Or slightly exceeds the threshold r 0 Passive postureThe state adjusting mechanism 7 rotates the movable basket 7.1 to the second station, the posture of the materials in the movable basket 7.1 is adjusted to the inclined posture, and then the rotating speed of the rotating assembly 4 is adjusted to the threshold value r 0 The following rotation speed r 1 The influence of slightly increasing the load of the servo motor in a very short time on the servo motor is very small, and at the moment, the movable basket 7.1 and the materials are kept in an inclined posture, so that the materials maintaining the inclined posture can be spin-dried, and the spin-drying and the dehydration of the materials are more thorough; it can be seen that the passive attitude adjusting mechanism 7 is mainly operated at the rotation speed r 1 To threshold r 0 In the section of (2), the material can be centrifugally dehydrated in two postures of an righting posture and an inclining posture respectively.
