DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] See also Figure 1-14, a rotating multi-station centrifugal drying device provided by an embodiment of the present invention includes a machine base 1, a gantry 3, a rotating assembly 4, a driving assembly, a manipulator 6 and a positioning assembly 5, wherein the rotating assembly 4 includes a rotating frame 4.1 and a plurality of water filter baskets 4.2, the rotating frame 4.1 is rotatably connected to the machine base 1 through a rotating shaft 2, and each water filter basket 4.2 is fixedly connected to the rotating frame 4.1 in a circumferential array, and each water filter basket 4.2 has a centrifugal position for placing materials, and the material port of each water filter basket 4.2 faces the rotation center of the rotating frame 4.1 and encloses a loading and unloading space; preferably, the number of water filter baskets 4.2 is 2-10; further, the number of water filter baskets 4.2 is 6, and the loading and unloading space is in the shape of a regular hexagonal prism; the driving assembly is arranged on the machine base 1, for driving the rotating assembly 4 to rotate, and the driving assembly is preferably a servo motor and supporting components (not shown in the figure), which is driven by the servo motor through the rotating shaft 2 The rotating assembly 4 rotates; the machine base 1 includes a base body 1.1 and an annular shell 1.2 fixedly connected to the base body 1.1, the annular shell 1.2 covers the rotating assembly 4, and the annular shell 1.2 can block the moisture thrown out during centrifugation; the manipulator 6 is arranged on the gantry 3, and the manipulator 6 has a clamping assembly 6.1 for clamping the material. The manipulator 6 is used to transfer the material in turn between the loading rack, any centrifugal station and the unloading rack. The loading rack is suitable for supplying materials to be dried, and the unloading rack is used to receive the dried materials; the positioning assembly 5 is used to position the rotating assembly 4 with the base after it stops, so that the centrifugal station is located on the movement path of the clamping assembly 6.1. Specifically, the positioning assembly 5 includes at least one proximity switch. The specific installation method and working principle of the proximity switch are existing technologies and will not be repeated here. The positioning assembly 5 can also adopt other components in the existing technology that have the ability of rotation stop positioning.

[0036] In the above technical solution, the present invention provides a rotating multi-station centrifugal drying equipment, in which the manipulator 6 can place the material (plastic pallet stack) evenly on each centrifugal station. The material is stable during the centrifugal process and the rotating component 4 rotates evenly. The material drying effect is good and the equipment loss is small. Each centrifugal station shares the same loading and unloading space, which can optimize the movement path of the manipulator 6. The material is loaded and unloaded by the manipulator 6, and the degree of manual dependence is low.

[0037] As a preferred technical solution of this embodiment, the manipulator 6 also includes a manipulator arm 6.2, a clamping assembly 6.1 is arranged at the end of the manipulator arm 6.2, and the clamping assembly 6.1 includes a back plate 6.11, a lower clamping jaw 6.12, an upper clamping jaw 6.13, a cylinder 6.14 and a limit rod 6.15, wherein the back plate 6.11 is fixedly connected to the end of the manipulator arm 6.2, the lower clamping jaw 6.12 is fixedly connected to the bottom of the back plate 6.11, and the upper clamping jaw 6.13 is vertically slidably connected to the upper end of the manipulator arm 6.2. On the back plate 6.11, the cylinder seat of the cylinder 6.14 is fixedly mounted on the back plate 6.11, and the power output end of the cylinder 6.14 is fixedly connected to the upper clamping jaw 6.13; preferably, a linear drive source such as a hydraulic cylinder or an electric push rod can be used instead of the cylinder 6.14; the limit rod 6.15 is connected to the back plate 6.11 through an elastic element 6.16, and the elastic element 6.16 is preferably an elastic telescopic rod, and the limit rod 6.15 is located between the upper clamping jaw 6.13 and the lower clamping jaw 6.12. The cylinder 6.14 can drive the upper clamping jaw 6.13 to move on the back plate 6.11, so that the upper clamping jaw 6.13 is close to or away from the lower clamping jaw 6.12, thereby clamping the material or opening the material, and can also be adjusted according to the thickness of the material; a limit rod 6.15 and an elastic element 6.16 are provided. On the one hand, the limit rod 6.15 and the elastic element 6.16 can be used to prevent the material from rigidly contacting the back plate 6.11, thereby protecting the material; on the other hand, when clamping the material, the limit rod 6.15 is used to press the material as much as possible, and the elastic element 6.16 is compressed to store energy, and then the cylinder 6.14 drives the upper clamping jaw 6.13 to clamp the lower clamping jaw 6.12 to close to clamp the material. When the manipulator 6 transfers the material to the centrifugal station, in some cases due to the space limitation of the centrifugal station, if the manipulator 6 cannot fully extend into the centrifugal station, it only needs to loosen the upper clamping jaw 6.13, and the elastic potential energy accumulated in the elastic element 6.16 is released, and the material on the lower clamping jaw 6.12 can be completely pushed into the centrifugal station through the limit rod 6.15.

[0038] In another embodiment provided by the present invention, a plurality of passive posture adjustment mechanisms 7 are further included, each of which corresponds to a water filter basket 4.2. The passive posture adjustment mechanism 7 can adjust the posture of the material on the corresponding centrifugal station during the centrifugal drying process. The passive posture adjustment mechanism 7 includes a movable basket 7.1, a rotating rod 7.2, a sliding member 7.4, a first elastic member 7.6, a rotating wheel 7.7, a second elastic member 7.8, a trigger member 7.9 and a heavy ball 7.10, wherein the movable basket 7.1 is rotatably connected to the corresponding water filter basket 4.2 through the shaft 7.16, and the material is placed in the movable basket 7.1. During the rotation of the movable basket 7.1 relative to the water filter basket 4.2, the movable basket 7.1 has: a first position that is straight relative to the water filter basket 4.2 The second working position that is inclined relative to the water filter basket 4.2; the rotating rod 7.2 is rotatably connected to the corresponding water filter basket 4.2 through the bracket 7.3, and one end of the rotating rod 7.2 abuts and cooperates with the movable basket 7.1. Specifically, the end of the rotating rod 7.2 is rotatably connected to the second roller 7.14, and the rotating rod 7.2 abuts against the movable basket 7.1 through the second roller 7.14, which can greatly reduce the friction resistance of the rotating rod 7.2 during the movement of the movable basket 7.1; further, the bracket 7.3 is fixedly connected to the limiting block 7.13, and during the upward rotation of one end of the rotating rod 7.2 abutting against the movable basket 7.1, the rotating rod 7.2 is in a horizontal state when abutting against the limiting block 7.13; the sliding member 7.4 is fixedly connected to the filter The connecting piece 7.5 on the water basket 4.2 is vertically slidably connected, and the sliding piece 7.4 has an abutment groove 7.41 and an abutment surface. The abutment surface includes a tangent arcuate surface 7.42 and a horizontal surface 7.43. The other end of the rotating rod 7.2 abuts in the abutment groove 7.41. Preferably, the other end of the rotating rod 7.2 is rotatably connected to a third roller 7.15, and the third roller 7.15 is located in the abutment groove 7.41. The third roller 7.15 abuts with the upper groove surface and the lower groove surface of the abutment groove 7.41 at the same time, that is, the third roller 7.15 can roll in the abutment groove 7.41, and the rotating rod 7.2 abuts and cooperates with the abutment groove 7.41 through the third roller 7.15, which can greatly reduce the friction resistance of the rotating rod 7.2 relative to the abutment groove 7.41 during movement. The first elastic member 7.6 has an elastic force that acts vertically downward on the sliding member 7.4. Preferably, the first elastic member 7.6 includes at least one tension spring, one end of which is fixedly connected to the bracket 7.3 and the other end of which is fixedly connected to the sliding member 7.4. The rotating wheel 7.7 is arranged on the connecting member 7.5 and moves in the radial direction of the water filter basket 4.2 in one direction of the rotating shaft 2. The rotating wheel 7.7 abuts and cooperates with the abutting surface. Specifically, the rotating wheel 7.7 is rotatably connected to its axis. The two ends of the axis of the rotating wheel 7.7 are respectively fixedly connected to support rods 7.11. A plurality of parallel first rollers 7.12 are rotatably connected to the two support rods 7.11. Each first roller 7.12 is in rolling connection with the connecting member 7.5, which can greatly reduce the relative movement of the rotating wheel 7.7 with the connecting member 7.5 frictional resistance during movement; the elastic force of the second elastic member 7.8 acts on the rotating wheel 7.7, and the direction of the elastic force of the second elastic member 7.8 is along the movement path of the rotating wheel 7.7 on the connecting member 7.5 and toward the rotating shaft 2. The second elastic member 7.8 is preferably a compression spring, one end of which abuts the connecting member 7.5, and the other end abuts the triggering member 7.9; the triggering member 7.9 is fixedly connected to the shaft of the rotating wheel 7.7 and has a concave arc surface; the heavy ball 7.10 is rollingly arranged in the guide groove 7.17 fixed to the connecting member 7.5. The guidance of the guide groove 7.17 is consistent with the movement path of the rotating wheel 7.7 on the connecting member 7.5. The triggering member 7.9 is located in the movement path of the heavy ball 7.10. The heavy ball 7.10 is a metal sphere or alloy sphere made of high-density material. Specifically, the heavy ball 7.10 is preferably a steel ball, a lead ball, or a tungsten ball.

[0039] The working principle of this embodiment is as follows: during the centrifugal drying of the material, when the rotation speed of the rotating assembly 4 is lower than a threshold value r0, the elastic force of the first elastic member 7.6 acts downward on the sliding member 7.4, and the abutting groove 7.41 of the sliding member 7.4 abuts against the third roller 7.15 at the end of the rotating rod 7.2. The rotating rod 7.2 is in a horizontal state under the limit of the limit block 7.13, and the movable basket 7.1 is in the first working position. The movable basket 7.1 remains upright. During the rotation of the rotating assembly 4, 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. The squeezing force of the heavy ball 7.10 on the trigger member 7.9 is not enough to overcome the pressure at this time. The elastic force of the first elastic member 7.6 and the elastic force of the second elastic member 7.8 (only the principle of the main forces is explained here, and there are many smaller forces such as friction between the corresponding components or centrifugal forces of other components in this process, but this does not hinder the explanation of the working principle of this embodiment), that is, the rotating wheel 7.7 is only in contact with the arc surface 7.42; when the speed of the rotating assembly 4 reaches or exceeds the threshold r0, the centrifugal force on the heavy ball 7.10 increases significantly, and the force of the heavy ball 7.10 on the trigger member 7.9 increases, overcoming the elastic force of the first elastic member 7.6 and the elastic force of the second elastic member 7.8 at this time, thereby driving the trigger member 7.9. The rotating wheel 7.7 moves along the guide groove 7.17, and the rotating wheel 7.7 rolls over the arc surface 7.42 to reach the horizontal surface 7.43, thereby moving the sliding member 7.4 upward. The sliding member 7.4 pulls the third roller 7.15 upward through the abutment groove 7.41, thereby rotating the rotating rod 7.2. Once the rotating rod 7.2 loses its horizontal posture, the centrifugal force of the movable basket 7.1 and the material inside causes the movable basket 7.1 and the material inside to rotate, and the movable basket 7.1 rotates to the second working position. The movable basket 7.1 and the material are adjusted to an inclined posture, thereby promoting the material drying effect; at this time, the speed of the rotating assembly 4 is reduced until the heavy ball 7.10 contacts the trigger member 7. When the force exerted by 9 is less than the elastic force of the second elastic member 7.8 (and the friction resistance between the corresponding moving parts, but excluding the elastic force of the first elastic member 7.6), the elastic force of the second elastic member 7.8 pushes the rotating wheel 7.7 away from the state of abutting against the horizontal surface 7.43. After the sliding member 7.4 loses the abutment of the rotating wheel 7.7 against its horizontal surface 7.43, the elastic force of the first elastic member 7.6 immediately moves the sliding member 7.4 downward. The sliding member 7.4 rotates the rotating rod 7.2 through the abutment groove 7.41. The rotating rod 7.2 overcomes the pressure of the movable frame and rotates the movable basket 7.1 to return to the first working position. At this time, the rotation speed r1 of the rotating assembly 4 is less than the threshold value.

[0040] The beneficial effects of this embodiment are as follows: First, compared with the prior art, in this embodiment, during the centrifugation process, the movable basket 7.1 and the material can be centrifugally dried while maintaining two different postures and a transition state between the two postures, which can effectively alleviate the situation where the centrifuged water in the single-posture material is blocked by the impermeable part of the material itself and cannot be separated from the material. The posture of the material changes during the centrifugation process, and the angle can be adjusted, so that the water can be easily thrown out, thereby achieving a better drying effect on the material and more sufficient drying and dehydration of the material; and the change in the centrifugal posture of the material is achieved during the centrifugation process by the centrifugal force generated by the rotation of the rotating component 4 through the passive posture adjustment mechanism 7, without the need for additional power system configuration, and the posture adjustment does not require the drive component and the rotating component 4 to be shut down. Secondly, driving the rotating assembly 4 to rotate the driving assembly requires power. Long-term high-power output can easily overload the servo motor and cause damage. Another advantage of the design of the passive posture adjustment mechanism 7 in this embodiment is that during the process of the rotating assembly 4 from starting to increasing to maintaining a speed close to the threshold r0, the movable basket 7.1 always remains in the first working position, and the material in the movable basket 7.1 is in a correct posture for centrifugal drying. The rotating assembly 4 and the driving assembly can maintain this speed safely and stably for a long time. When the material drying effect needs to be further improved after running for a period of time, it is only necessary to briefly increase the speed of the rotating assembly 4 to the threshold r0 or slightly exceed the threshold r0. , the passive posture adjustment mechanism 7 rotates the movable basket 7.1 to the second working position, and the posture of the material in the movable basket 7.1 is adjusted to an inclined posture, and then the speed of the rotating component 4 is reduced to below the threshold r0 and above the speed r1. The slight increase in the servo motor load for a very short time has little effect on the servo motor. At this time, the movable basket 7.1 and the material are maintained in an inclined posture, and the material maintaining the inclined posture can be dried, making the drying and dehydration of the material more thorough; it can be seen that the core function of the passive posture adjustment mechanism 7 is that in the range of the speed r1 to the threshold r0, the material can be centrifugally dehydrated in two postures, namely, a straight posture and an inclined posture.

[0041] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
