And can prevent excessive deposition of the filling material at the bottom of the inner cylinder 2 or at a certain position, thereby keeping the inner cylinder 2 clean, and more importantly, the centrifugal force generated by rotation can be adjusted to adjust the thickness and the quality of the filling or coating material on the surface of the blank.
An annular block 28 is arranged on the outer wall of the rotating shaft 12, a placement groove 29 matched with the annular block 28 is formed in the inner wall of the lifting rod 7, so that the annular block 28 rotates in the placement groove 29, and therefore the rotating shaft 12 is connected with the lifting rod 7 through the matching of the annular block 28 and the placement groove 29, and the lifting rod 7 drives the rotating shaft 12 to move in the ascending or descending process;
the gap between the rotating shaft 12 and the lifting rod 7 can be sealed through a sealing element, the rotating shaft 12 can be connected and disconnected, the connection and disconnection modes of the rotating shaft 12 are various, the connection and disconnection modes are not limited in particular, for example, the rotating shaft 12 can be composed of a first rotating shaft, a second rotating shaft and a third rotating shaft, splines 27 are respectively arranged on the first rotating shaft and the third rotating shaft, spline grooves matched with the first rotating shaft and the third rotating shaft are respectively arranged at two ends of the second rotating shaft, so that the splines 27 are tightly matched with the spline grooves, synchronous rotation between the first rotating shaft, the second rotating shaft and the third rotating shaft is realized, relative sliding is prevented, a certain positioning effect is realized, effective transmission of power is ensured, and an annular block 28 is arranged on the upper outer wall of the second rotating shaft, so that the annular block 28 is matched with the placement groove 29 through the annular block 28 and the lifting rod 7;
the mode of two connection of the first rotating shaft, the second rotating shaft and the third rotating shaft is not limited, T-shaped thread grooves are formed in the first rotating shaft and the third rotating shaft, and T-shaped bolts matched with the T-shaped thread grooves are respectively arranged at two ends of the second rotating shaft.
It should be noted that, the lifter 8 includes a worm gear, a worm, a motor and a mounting shell disposed on the supporting platform, an output end of the motor is connected with the worm, the worm is engaged with the worm gear, a plurality of tooth grooves engaged with the worm gear are disposed on the lifter 7, and when the lifter 7 lifts, the driving device can be linked to drive the rotation shaft 12 to rotate. Then a motor is needed to drive the lifting rod 7 to lift and the rotating shaft 12 to rotate, so that the overall energy consumption can be reduced, and the motor drives the rotating shaft 12, so that the motion control can be more effectively performed through accurate control, the error is reduced, and the overall working efficiency is improved. Multiple motors can generate more noise during operation, and the influence can be reduced by using a single motor, so that user experience is improved.
It should be noted that the driving device includes a first linear groove 14, a second linear groove 16 and a spiral groove 15 formed on the rotating shaft 12, one side of the spiral groove 15 is communicated with the first linear groove 14, the other side of the spiral groove 15 is communicated with the second linear groove 16, the first linear groove 14 is near the bottom direction of the can body 1 on the rotating shaft 12, a connecting frame 17 is provided on the can body 1, and a fixing block 18 matched with the first linear groove 14, the second linear groove 16 and the spiral groove 15 is provided on the connecting frame 17. In the lifting process of the lifting rod 7, the rotating shaft 12 ascends together, the end part of the rotating shaft 12 penetrates through the lifting rod 7 to extend outwards, the extending end of the rotating shaft 12 is located above the lifting rod 7, the initial state of the fixed block 18 is located in the first linear groove 14, when the lifting rod 7 drives the rotating shaft 12 to ascend, the fixed block 18 moves in the first linear groove 14, the rotating shaft 12 does not rotate at the moment, but the lifting rod 7 drives the heat shield inner cover 10 to be separated from the cap peak 11 of the outer cylinder 3, the lifting rod 7 continues to lift, the fixed block 18 enters the spiral groove 15, and when the spiral groove 15 on the rotating shaft 12 contacts the fixed block 18 and performs linear movement, the spiral groove 15 is distributed spirally along the rotating shaft 12, so that in the process of contacting with the fixed block 18, a rotary movement is generated relative to the fixed block 18. This is just as if the screw were rotating inside the nut, even though the screw is doing a linear motion, it will rotate relative to the fixed nut due to the design of the screw. Likewise, the rotating shaft 12 rotates due to the interaction with the fixed block 18. Finally, the fixing block 18 is matched with the second linear groove 16, so that the rotating shaft 12 of the device can stably ascend, the lifting rod 7 and the rotating shaft 12 can synchronously move, when the air holes 5 and the through holes 6 in the inner cylinder 2 are also arranged in the outer cylinder 3, the inner cylinder 2 rotates, and liquid melted by some filling materials can be discharged from the through holes 6 or the air holes 5 to enter the outer cylinder 3, so that the separation effect is improved. However, if the air hole 5 or the through hole 6 leaves the outer cylinder 3, the lifting rotation is still performed, the liquid discharged from the inner cylinder 2 may enter the inner wall of the heat insulation layer 4, once the liquid enters the inner wall of the heat insulation layer 4, the liquid may adhere to the heat insulation layer 4 and is difficult to clean, the long-term accumulation may affect the heat insulation effect, and if the discharged liquid is corrosive, the discharged liquid may damage the inner wall of the heat insulation layer 4, thereby shortening the service life of the device.
If the rotation shaft 12 is simply controlled by a motor, the rotation of the inner tube 2 is still performed by the inertia of the rotation shaft 12 after the motor is stopped, and it cannot be ensured that the rotation of the inner tube 2 is stopped when the air hole 5 or the through hole 6 is separated from the outer tube 3.
However, if the first linear groove 14, the spiral groove 15 and the second linear groove 16 are matched with the fixed block 18, the movement of the rotating shaft 12 can be controlled more precisely. When the motor drives the fixed block 18 to move along the linear groove or the spiral groove 15, the rotation shaft 12 rotates accordingly. However, when the motor is stopped, the lifting lever 7 is stopped, and the rotation shaft 12 is also stopped, the rotation shaft 12 cannot continue to move or rotate independently of the fixing block 18 due to the engagement between the fixing block 18 and the groove, that is, it cannot continue to rotate due to inertia. This is mainly because the contact of the fixed block 18 with the recess is a rigid contact which can prevent the rotation shaft 12 from continuing to rotate due to inertia.
In addition, the second linear groove 16 is a safety design, and when the second linear groove 16 is engaged with the fixed block 18, the rotation shaft 12 is forced to stop rotating, because in this position the fixed block 18 no longer moves along the spiral path, and the rotation shaft 12 cannot rotate. The problem of the rotation shaft 12 still rotating when the air hole 5 or the through hole 6 is separated from the outer cylinder 3 can be avoided.
The composite or cladding manufacturing of filling materials with different melting points and blanks can be solved through the structure, so that the production requirements of different melting points and different production process requirements are met, and the production specification of products can be amplified randomly.
