The first cylinder 3 and the second cylinder 4 are both vertically mounted in the mounting frame 1. The second cylinder 4 is mounted on the top of the piston rod of the first cylinder 3. The piston rod of the second cylinder 4 extends out of the mounting frame 1 and extends between the two conveyor belts 2 and is connected to the sagger top plate 5. The first cylinder 3 drives the second cylinder 4 to rise and fall in the mounting frame 1.

Through the joint action of the first cylinder 3 and the second cylinder 4, the sagger transported by the conveyor belt 2 is moved to different positions.

[0031] Compared with the existing lifting mechanism, the double-layer lifting mechanism adjusts the position of the sagger top plate through the mutual cooperation of the first cylinder and the second cylinder. The double-layer lifting mechanism has a simple structure, good stability, low failure rate during use, easy maintenance, and improves the service life of the double-layer lifting mechanism.

[0032] In one embodiment of the present disclosure, the mounting frame 1 and the conveyor belt 2 are connected via a mounting plate.

[0034] Optionally, the mounting plate is fixedly mounted on the top of the mounting frame 1, and the conveyor belt 2 is detachably mounted on the top of the mounting plate.

[0035] In one embodiment of the present disclosure, the extension and retraction of the piston rods of the first cylinder 3 and the second cylinder 4 are both controlled by solenoid valves, and the movement speed of the piston rods of the first cylinder 3 and the second cylinder 4 are both controlled by regulating valves. The movement speed of the piston rod of the first cylinder 3 is greater than the movement speed of the piston rod of the second cylinder 4, and the speed of the piston rod of the second cylinder 4 when extending shows a decreasing curve.

[0036] In one embodiment of the present disclosure, see Figure 1 and Figure 2 The bottom frame of the mounting frame 1 is provided with a concave plate 6, and the first cylinder 3 is arranged on the inner wall of the bottom end of the concave plate 6. In this way, the first cylinder 3 can be installed in the mounting frame 1, and then the second cylinder 4 can be installed in the mounting frame 1, which improves the stability of the double-layer lifting mechanism and facilitates the maintenance of the first cylinder 3 and the second cylinder 4.

[0037] In one embodiment of the present disclosure, see Figure 2 The first cylinder 3 is a three-axis cylinder; the ends of the three piston rods of the first cylinder 3 are provided with a first connecting plate 7, the top of which is provided with a support plate 8, and the second cylinder 4 is provided on top of the support plate 8. In this way, the driving force of the first cylinder 3 can be improved, making it easier for the first cylinder 3 to drive the second cylinder 4 and the upper sagger top plate 5 to rise and fall, while also improving the stability of the second cylinder 4 when rising and falling.

[0038] In one embodiment of the present disclosure, see Figures 1 to 3 The end of the piston rod of the second cylinder 4 is provided with a second connecting plate 9, the sagger top plate 5 is provided on the top of the second connecting plate 9, and the four corners of the surface of the sagger top plate 5 are respectively provided with limit blocks 10. In this way, the firmness of the connection between the second cylinder 4 and the sagger top plate 5 can be improved, the second cylinder 4 can be used to drive the sagger top plate 5 to rise and fall, and the stability of the sagger top plate 5 in rising and falling can be improved.

[0039] In one embodiment of the present disclosure, see Figure 1 and Figure 2 A first dust cover 11 is provided on the first cylinder 3. One end of the first dust cover 11 is connected to the inner wall of the bottom end of the concave plate 6, and the other end of the first dust cover 11 is connected to the bottom end of the support plate 8. In this way, the first cylinder 3 can be protected from dust contamination, malfunction of the first cylinder 3 can be avoided, and the service life of the first cylinder 3 can be increased.

[0040] In one embodiment of the present disclosure, see Figure 1 and Figure 2A second dust cover 12 is provided on the second cylinder 4, one end of the second dust cover 12 is connected to the bottom end of the sagger top plate 5, and the other end of the second dust cover 12 is connected to the top end of the support plate 8. In this way, the second cylinder 4 can be protected, the second cylinder 4 can be prevented from being contaminated by dust, the second cylinder 4 can be prevented from malfunctioning, and the service life of the second cylinder 4 can be increased.

[0041] In one embodiment of the present disclosure, see Figure 1 and Figure 2 A wire dust cover 13 is provided on the second dust cover 12. One end of the wire dust cover 13 is connected to the top of the support plate 8, and the other end of the wire dust cover 13 is connected to the top frame of the mounting frame 1. In this way, the second dust cover 12 can be protected, and multiple protections can be achieved for the second cylinder 4, thereby extending the service life of the second cylinder 4 and the second dust cover 12.

[0042] In one embodiment of the present disclosure, see Figure 1 and Figure 2 The first dust cover 11, the second dust cover 12, and the wire dust cover 13 are all foldable dust covers. Thus, the states of the first dust cover 11, the second dust cover 12, and the wire dust cover 13 can change according to the states of the first cylinder 3 and the second cylinder 4, thereby achieving all-round protection for the first cylinder 3 and the second cylinder 4 and extending the service life of the first cylinder 3 and the second cylinder 4.

[0043] In one embodiment of the present disclosure, see Figure 2 and Figure 3 The second dust cover 12 is provided with a limiting plate 14, which is arranged on the inner wall of the bottom end of the two conveyor belts 2, and the limiting plate 14 is fixedly connected to the second dust cover 12. In this way, the sagger top plate 5 can be limited to prevent the sagger top plate 5 from entering the mounting frame 1, thereby limiting the movement range of the sagger top plate 5.

[0044] Optionally, the limiting plate 14 may be fixedly connected to the conveyor belt 2 or detachably connected to the conveyor belt 2 .

[0045] In one embodiment of the present disclosure, see Figure 2 , the size of the support plate 8 is larger than the inner diameter of the limit plate 14, and the size of the sagger top plate 5 is larger than the inner diameter of the limit plate 14. In this way, the support plate 8 can only move below the limit plate 14, and the sagger top plate 5 can only move above the limit plate 14.

[0046] It can be understood that the support plate 8 limits the telescopic range of the piston rod of the first cylinder 3, thereby limiting the lifting range of the second cylinder 4, and the limit plate 14 limits the telescopic range of the piston rod of the second cylinder 4, thereby limiting the lifting range of the sagger top plate 5. In this way, the support plate 8 and the limit plate 14 cooperate to limit the lifting height range of the sagger top plate 5.

[0047] In one embodiment of the present disclosure, see Figure 2 The top of the cylinder body of the first cylinder 3 is provided with a first groove 15, and the top of the cylinder body of the second cylinder 4 is provided with a second groove 16. A first magnetic induction switch is provided in the first groove 15, and a second magnetic induction switch is provided in the second groove 16. In this way, the real-time status of the first cylinder 3 and the second cylinder 4 can be detected, which facilitates the cooperation between the first cylinder 3 and the second cylinder 4 to move the sagger to different positions.

[0048] In one embodiment of the present disclosure, see Figure 2 , the four corners of the bottom end of the mounting frame 1 are respectively provided with bases 17. In this way, the mounting frame 1 can be supported and the stability of the double-layer lifting mechanism can be improved.

[0049] In one embodiment of the present disclosure, the conveyor belt 2 is detachably mounted on the top of the mounting plate, and the limit plate 14 is detachably mounted on the conveyor belt 2. After the first cylinder 3 is installed, there is a certain distance between the first cylinder 3 and the ground. This allows for convenient adjustment of the position of the lifting mechanism on the conveyor belt 2, facilitating the use of the sintering furnace.

[0050] In one embodiment of the present disclosure, see Figures 1 to 3 The working process of the double-layer lifting mechanism used in the lithium battery positive electrode material sintering furnace is briefly described as follows:

[0051] When the present invention is in use, the lifting mechanism is first installed on the conveyor belt 2. When the sagger needs to be lifted, the first cylinder 3 is started by the electromagnetic valve, the piston rod of the first cylinder 3 is extended, and the second cylinder 4 is driven to rise. When the first magnetic induction switch senses that the piston rod of the first cylinder 3 is in place, the first cylinder 3 is closed and the second cylinder 4 is started by the electromagnetic valve. The piston rod of the second cylinder 4 is extended, driving the sagger top plate 5 to rise and lift the sagger on the conveyor belt 2. When the lifting mechanism needs to be restored to its original state, the first cylinder 3 is started by the electromagnetic valve, the first cylinder 3 is started, the first The piston rod of the air cylinder 3 retracts, driving the second air cylinder 4 to descend. When the first magnetic induction switch senses that the piston rod of the first air cylinder 3 is in place, the first air cylinder 3 is closed, and the second air cylinder 4 is started through the electromagnetic valve. The piston rod of the second air cylinder 4 retracts, driving the sagger top plate 5 to descend, so that the second air cylinder 4 and the sagger top plate 5 are lowered back to the origin. During the operation of the first air cylinder 3 and the second air cylinder 4, the speed of movement of the piston rod of the first air cylinder 3 is greater than the speed of movement of the piston rod of the second air cylinder 4, and the speed of the piston rod of the second air cylinder 4 when it is extended shows a decreasing curve.
