[0034] like Figure 1-14 The lifting and rotating mechanism of the aerosolized rod shown in the figure includes a fixedly arranged sealing shell 1, the main part of the sealing shell 1 is a guide cylinder 101, the guide cylinder 101 is roughly cylindrical, and most of the inner and outer walls are coaxial cylindrical sides. The upper end of the guide cylinder 101 is fixedly connected to an upper mounting plate 103, which is used to be fixedly connected to the frame through bolts and other connecting parts. A telescopic mechanism 2 is arranged on the top of the sealing shell 1, and the movable end of the telescopic mechanism 2 extends into the guide cylinder 101 and is movably connected to a clamping mechanism 3 for clamping the rod body 4. The specific structure of the telescopic mechanism 2 includes a cylinder 201 fixedly connected to the upper mounting plate 103, and a telescopic rod 202 is movably connected in the cylinder 201. The actual The top is a hydraulic cylinder, which can provide a large longitudinal pulling force. The movable end of the telescopic rod 202 extends into the guide cylinder 101 and is fixedly connected to a force ring 203. A clamping groove 204 is formed between the top surface of the force ring 203 and the side surface of the telescopic rod 202. The clamping mechanism 3 includes a linkage part 310. The main part of the linkage part 310 is a turntable 311 rotatably connected to the movable end of the telescopic mechanism 2. Specifically: a yield groove 315 is provided on the top surface of the turntable 311, which just fits with the force ring 203, and a clamping ring 316 located around the upper edge of the yield groove 315 is fixedly connected to the top surface of the turntable 311, which just cooperates with the clamping groove 204 to form a rotating pair, so the turntable 311 rotates coaxially relative to the telescopic rod 202.

[0035] The bottom surface of the turntable 311 is fixedly connected with a driving part 330 for realizing clamping and releasing actions. The bottom surface of the turntable 311 is also rotatably connected with a plurality of clamping parts 320. The movable end of the driving part 330 is rotatably connected with a plurality of traction parts 340. The number and position of the traction parts 340 correspond to those of the clamping parts 320. The traction parts 340 can drive the clamping parts 320 to swing, and the swing of the clamping parts 320 is synchronous. The bottom surface of the turntable 311 is provided with a configuration groove 313 for reserving more installation space for the driving part 330. The driving part 330 includes a cylinder seat 331 fixedly connected to the configuration groove 313. A piston 332 is slidably connected inside the cylinder seat 331. In fact, the piston 332 and the cylinder seat 331 cooperate to form a hydraulic cylinder structure that can provide a strong force, but the hydraulic cylinder structure is very flat. The lower end of the piston 332 extends to the outside of the cylinder seat 331 and is fixedly connected to a traction plate 333. The traction plate 333 is coaxial with the piston 332, and the axis is usually coaxial with the axis of the turntable 311. The bottom surface of the traction plate 333 is fixedly connected to a sensor 334, which is generally a pressure type. By detecting the pressure applied by the rod body 4, it is determined whether the end of the rod body 4 has reached a clampable position.

[0036] The specific structure of the clamping part 320 includes a swing arm 321, an upper hole 323 is formed at the upper end of the swing arm 321, and a lower hole 324 is formed at the lower end, and the axes of the two holes are parallel. The bottom surface of the rotating disk 311 is fixedly connected with a first synchronous shaft 314, which is used to cooperate with the upper hole 323 to form a rotating pair; a shaft groove 335 is formed on the side of the traction disk 333, and the traction disk 333 is fixedly connected with a second synchronous shaft 336 in the shaft groove 335, which is parallel to the axis of the first synchronous shaft 314. The upper end of the traction part 340 is provided with a hinge hole 342, which is used to connect with the second synchronous shaft 336. Cooperate to form a rotating pair; the lower end of the traction part 340 is fixedly connected with a hinge shaft 341, which is parallel to the axis of the hinge hole 342, and is used to cooperate with the lower hole 324 to form a rotating pair, so that the various rotating pairs will not interfere with each other when in action. The lower end of the swing arm 321 is also fixedly connected with a hoop plate 322, and the inner wall diameter of the hoop plate 322 is equal to the diameter of the rod body 4. The hoop plate 322 is used to directly contact the rod body 4 and apply a force, including an extrusion force and a friction force. In order to enhance the contact friction force, a rubber pad structure is usually provided on the arc-shaped inner surface of the hoop plate 322.

[0037] A spiral groove 312 is provided on the outer side surface of the turntable 311, and the inner wall of the guide cylinder 101 has a spiral edge 108, which is exactly engaged with the spiral groove 312. In this embodiment, there are several spiral edges 108 on the inner wall of the guide cylinder 101, and these spiral edges 108 are arranged equidistantly around the axis of the guide cylinder 101. There are also several spiral grooves 312 provided on the outer side surface of the turntable 311, and the number and position correspond to the spiral edges 108. After the turntable 311 cooperates with the guide cylinder 101 in this way, it can rotate during the lifting process, so that the clamped rod body 4 descends in a spiral form, and the materials at various angles of the lower end of the rod body 4 are more likely to gather at the same position after melting, which is beneficial to improving the uniformity of atomization.

[0038] The guide cylinder 101 is provided with a feed groove 105 which passes through the inner and outer walls for the rod body 4 to enter the guide cylinder 101. Of course, the feed groove 105 is not open, but is blocked by other components, such as the storage structure of the rod body 4. Therefore, the sealing shell 1 is still sealed. The bottom of the guide cylinder 101 is provided with a convergence sleeve 102. The inner diameter of the convergence sleeve 102 is only slightly larger than the rod body 4, usually only one millimeter. The inner wall of the convergence sleeve 102 gradually narrows from the upper end to the bottom, and a part of the lower end is a cylindrical surface, so that the rod body 4 passing through the feed groove 105 can slide in and remain vertical. The lower end of the guide cylinder 101 is fixedly connected to a lower mounting plate 104, which is also used to be fixedly connected to the frame. In fact, the convergence sleeve 102 is fixedly connected to the guide cylinder 101 through the lower mounting plate 104.

[0039] The bottom of the sealing shell 1 is also provided with a limiting mechanism 5 for maintaining the position of the rod body 4 stable. The limiting mechanism 5 includes two parts: a cylinder 510 and a snap button 520. The snap button 520 is rotatably connected to the contraction sleeve 102. The two ends of the cylinder 510 are rotatably connected to the lower mounting plate 104 and the snap button 520, respectively. Specifically, the bottom surface of the lower mounting plate 104 is fixedly connected with a first fixed shaft 106, which is rotatably connected to the upper end of the cylinder 510. The snap button 520 includes a shaft sleeve 523, and the shaft sleeve 523 has a shaft hole 520 passing through both ends. 4. The lower end of the tightening sleeve 102 is fixedly connected with a second fixed shaft 107, which is parallel to the axis of the first fixed shaft 106 and is usually in the horizontal direction, and is used to cooperate with the shaft hole 524 to form a rotating pair. The outer side surface of the sleeve 523 has a seesaw 521 and a baffle 522, and the extension directions of the two are different. The end of the seesaw 521 is rotatably connected to the lower end of the cylinder 510, and the end of the baffle 522 can be located below the rod body 4, and can also leave the bottom of the rod body 4 after rotating around the axis of the second fixed shaft 107.

[0040] Working principle: When in use, the rod body 4 is discharged from the storage component, slides into the guide cylinder 101 through the feed slot 105, and the lower end of the rod body 4 slides into the tightening sleeve 102, and the lower end surface of the rod body 4 contacts the baffle 522, thereby being restricted in the vertical direction and remaining motionless. The clamping mechanism 3 descends under the drive of the telescopic mechanism 2. When the upper end of the rod body 4 hits the sensor 334, the hoop plate 322 will approach each other under the drive of the driving part 330 and clamp the upper end of the rod body 4. Then the cylinder 510 can shrink and release the restriction of the baffle 522 on the rod body 4. The telescopic mechanism 2 continues to drive the clamping mechanism 3, connecting the rod body 4 to rotate and feed downward.

[0041] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
