[0013] Optionally, an arc surface for abutting against the baffle is provided on the side of the baffle close to the guiding block.
[0014] By adopting the above technical solutions, by setting the arc surface, the contact position between the baffle and the guiding block can be smoother, reducing the situation of damage caused by interference between the baffle and the guiding block and improving the service life.
[0015] Optionally, the driving member includes an oil cylinder. The oil cylinder is fixedly connected to the side wall of the calcination box. A push rod is fixedly connected to the piston rod of the oil cylinder. The push rod extends into the interior of the calcination box and is fixedly connected to the pushing plate.
[0016] By adopting the above technical solutions, setting the oil cylinder to push the push rod and then using the push rod to push the pushing plate has a large driving force and high driving efficiency.
[0017] Optionally, a conveyor is provided on the calcination box. The conveyor is fixedly connected to the calcination box and is in communication with the calcination box.
[0018] By adopting the above technical solutions, setting the conveyor can directly convey the raw materials, eliminating the need to transport them to the calcination box for combustion after transportation, improving the convenience of production.
[0019] Optionally, a plurality of conveyors are provided and are arranged around the calcination box.
[0020] By adopting the above technical solution, multiple conveyors are provided, which can feed multiple groups of raw materials simultaneously or feed raw materials from multiple directions, further improving the convenience of production.

[0032] The following further details the present application with reference to the drawings through specific embodiments.
[0033] A positive electrode sheet calcining device, as shown in Figure 1 and Figure 2As shown in the figure, it includes a calcination box 1. An outlet 11 is provided on the side wall of the calcination box 1. A sealing cover 111 is provided on the side wall of the calcination box 1 corresponding to the outlet 11. One side of the sealing cover 111 is detachably connected to the calcination box 1, and the other side of the sealing cover 111 is hinged to the calcination box 1. A pushing plate 2 and a driving member are provided at the bottom of the calcination box 1. The pushing plate 2 is arranged along the width direction of the calcination box 1, and the driving member is used to drive the pushing plate 2 to slide along the length direction of the calcination box 1 towards the outlet 11. Specifically, during implementation, the inside of the calcination box 1 can be heated by flame combustion or by electric heating. After the calcination is completed, the raw materials can be sent towards the outlet 11 under the push of the pushing plate 2. At this time, only by opening the sealing cover 111 can the raw materials be conveniently sent out from the outlet 11.
[0034] As Figure 2 and Figure 3 shown in the figure, baffles 21 are provided at both ends of the pushing plate 2 in the length direction. The baffles 21 are arranged perpendicular to the pushing plate 2. The baffles 21 are slidably connected to the pushing plate 2. A guiding block 12 is provided on one side of the calcination box 1 close to the outlet 11. The guiding block 12 is triangularly arranged and is used to abut against the baffle 21. After the baffle 21 abuts against the guiding block 12, they move towards each other. A reset member is also provided on the pushing plate 2 for resetting the baffle 21. An arc surface 211 for abutting against the baffle 21 is provided on one side of the baffle 21 close to the guiding block 12. Specifically, when the pushing plate 2 moves towards the outlet 11, the baffles 21 can move towards each other under the guidance of the guiding block 12, so as to pile up the raw materials in the middle for sending, thereby further improving the convenience of collection during sending. At the same time, the baffles 21 can reduce the situation of raw materials leaking from the sides. After the pushing plate 2 is reset after the sending is completed, the baffles 21 can also return to their original positions under the reset of the reset member, facilitating the subsequent sending of the raw materials. The arc surface 211 can reduce the interference between the baffle 21 and the guiding block 12.
[0035] As Figure 2 and Figure 3 shown in the figure, sliding grooves 22 are provided on the pushing plate 2 corresponding to the baffles 21. Guide rods 221 are arranged in the sliding grooves 22. The guide rods 221 are arranged along the sliding grooves 22. The baffles 21 are slidably connected in the sliding grooves 22 and are also slidably connected to the guide rods 221. The reset member includes a spring 222. The spring 222 is sleeved on the guide rod 221. One end of the spring 222 abuts against the groove wall of the sliding groove 22, and the other end of the spring 222 abuts against the baffle 21. The spring 222 has a tendency to push the baffle 21 towards the end of the pushing plate 2. Specifically, during implementation, the spring 222 can push the baffle 21 towards both sides, thereby resetting the baffle 21.
[0036] As Figure 2 and Figure 3As shown in the figure, the driving member includes an oil cylinder 4, which is fixedly connected to the side wall of the calcination box 1. A push rod 23 is fixedly connected to the piston rod of the oil cylinder 4, and the push rod 23 extends into the interior of the calcination box 1 and is fixedly connected to the push plate 2. During specific implementation, the oil cylinder 4 can send the push rod 23 to send the push plate 2 towards the discharge port 11.
[0037] As Figure 2 and Figure 3 shown in the figure, a conveyor 3 is provided on the calcination box 1. The conveyor 3 is fixedly connected to the calcination box 1 and is in communication with the calcination box 1. There are multiple conveyors 3 and they are arranged around the calcination box 1. During specific implementation, the raw materials can be fed from multiple sides, which can improve the convenience of feeding the raw materials, and reduce the process of transporting the raw materials before production, further improving the production efficiency.
[0038] Working principle: The raw materials are fed from the conveyor 3. After being fed, they can be calcined in the calcination box 1. After the calcination is completed, the raw materials can be sent towards the discharge port 11 under the push of the push plate 2. When being sent out, the raw materials can be piled up at the discharge port 11 under the guidance of the guide plate, thereby further improving the collection rate of the product and reducing the situation that some raw materials stay in the calcination box 1.
