DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6 The utility model provides a technical solution: a pole piece baking machine for lithium battery production with rotatable materials, including a baking machine body 1, a blowing device 2, a heating device 3, a baking rack 4, a connecting bolt 5, a fixed splint 6, a movable column 7, a fixed column 8, a fixed bolt 9, a support frame 10, a support rod 11, a dustproof net 12, a fixing mechanism 13, an auxiliary block 14, a positioning column 15, a spring 16, a limit block 17 and a positioning block 18.

[0031] When using the lithium battery production pole piece baking machine with the rotatable material, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, first, the electrode to be baked is placed in the middle of the baking rack 4, and then the connecting bolts 5 connected to the left and right ends of the baking rack 4 are rotated by rotating the threaded connection bolts 5, and the connecting bolts 5 and the fixed clamping plates 6 are rotated, and the connecting bolts 5 drive the fixed clamping plates 6 to extend and retract in the middle of the baking rack 4, so as to facilitate clamping of the electrode. After the clamping is completed, the baking rack 4 is driven by the movable column 7 to be placed on the upper end of the baking machine body 1, and the movable column 7 is connected with the baking machine body 1 by a slot, and the movable column 7 drives the fixed column 8 to be placed in the middle of the support frame 10, and the support frame 10 is connected with the support rod 11 by a slot, and then the above operation is repeated, and the baking racks 4 with the electrode are arranged at equal intervals on the upper end of the baking machine body 1, so as to facilitate batch baking of the electrode.

[0032] After the placement is completed, the device is connected to the power supply, and the blowing device 2 and the heating device 3 installed at the bottom of the baking machine body 1 are started. The heating device 3 heats the air blown by the blowing device 2, so as to facilitate the baking of the electrode. A dustproof net 12 is arranged above the heating device 3. The dustproof net 12 can prevent dust from being blown to the electrode, which plays a good dustproof role. In the actual baking process, by rotating the fixing bolt 9, the fixing bolt 9 and the fixing column 8 and the fixing bolt 9 and the movable column 7 are all threadedly connected. The fixing bolt 9 loosens the limit between the fixed column 8 and the movable column 7, and then the movable column 7 is rotated. The movable column 7 rotates in the middle of the fixed column 8, and the movable column 7 drives the baking rack 4 to flip in the baking machine body 1. When flipped to 180°, the fixing bolt 9 is rotated in the opposite direction to fix the fixed column 8 and the movable column 7, so as to facilitate double-sided baking of the electrode, achieve a more sufficient baking effect, and greatly improve the actual baking efficiency.

[0033] In addition, if Figure 5 and Figure 6 As shown, after use, the power is turned off, and the fixing mechanism 13 includes an auxiliary block 14 fixedly connected to the right end of the baking machine body 1, a positioning column 15 hingedly connected to the middle part of the auxiliary block 14, a spring 16 sleeved on the outer surface of the positioning column 15, a limit block 17 fixedly connected to the movable end of the spring 16 and a positioning block 18 for limiting. By pulling the limit block 17 upward, the limit block 17 slides in the middle part of the positioning column 15, the limit block 17 squeezes the spring 16, so that the spring 16 undergoes elastic deformation, the limit block 17 moves upward and disengages from the positioning block 18, thereby releasing the limit on the positioning column 15, and then flipping the positioning column 15 outward, the positioning column 15 rotates with the auxiliary block 14, thereby releasing the limit on the dustproof net 12, and then pulling the dustproof net 12 to the right to pull the dustproof net 12 out of the baking machine body 1, so as to facilitate the disassembly and cleaning of the dustproof net 12 to prevent excessive dust attached to the dustproof net 12 from causing blockage.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
