Description

Technical Field

[0001] The utility model relates to the technical field of pole piece production, in particular to a pole piece drying device capable of uniformly heating. Background Art

[0002] The electrode is the energy storage core of the battery. During the preparation process, after the electrode is coated, the coating layer will contain moisture, and the moisture will affect the performance of the electrode during use. Therefore, after the electrode is coated, a drying device is needed to dry the moisture on its surface so that the moisture inside the coating layer can be discharged and the activity of the coating layer can be maintained.

[0003] The above has the following disadvantages when used:

[0004] When drying electrodes in an existing drying box, due to the long length of the electrode, a longer drying box needs to be set up, so that the drying box will occupy a larger space. In addition, due to the long length of the drying box, the drying box will consume more resources during use, thereby increasing the cost of electrode manufacturing.

[0005] To this end, we propose a pole piece drying device that can heat evenly to solve the above problems. Utility Model Content

[0006] The utility model provides a pole piece drying device which can heat evenly, which solves the technical problems that when drying pole pieces in the existing drying box, a longer drying box needs to be provided due to the longer pole pieces, so that the drying box occupies a larger space, and because the drying box is longer, more resources are consumed when in use, thereby increasing the cost of pole piece manufacturing.

[0007] In order to solve the above technical problems, the utility model provides a pole piece drying device capable of uniform heating, comprising: a drying assembly, including a drying box;

[0012] Furthermore, the outer surface of the support column has a threaded structure opened relative to the fixing bolt, and the support column is located inside the second through hole.

[0013] By screwing the fixing bolts on the outer surface of the support column, the support column can be fixed at the positions on both sides of the drying box, and by changing the position of the support column, the position of the support roller can be driven to change.

[0014] Furthermore, the support plate and the movable plate are located at two end positions inside the second through hole, and the outer end of the movable plate and the telescopic spring are located inside the support plate.

[0015] The support plate is used to support the movable plate. The movable plate can move inside the support plate. When the movable plate moves toward the support plate, the telescopic spring is driven to be compressed.

[0016] Furthermore, the ventilation component includes an air inlet connected to one side of the upper end of the drying box, a first gas flow sensor connected to the central position inside the air inlet, an air outlet connected to the other side of the upper end of the drying box, and a second gas flow sensor connected to the central position inside the air outlet.

[0017] The air inlet is used to discharge hot air into the drying box, the first flow sensor is used to measure the hot air flow rate of the air inlet, the air outlet is used to discharge the air inside the drying box to the outside, and the second gas flow sensor is used to measure the air flow rate of the air outlet.

[0018] Furthermore, the air inlet and the air outlet are respectively located at the outer ends of the first through hole, and the outer end of the air inlet is connected to a heating pump, and the outer end of the air outlet is connected to an exhaust pump.

[0019] The hot air can be discharged into the drying box through the heating pump, so that the temperature inside the drying box is maintained at a certain level, thereby drying the electrode.

[0020] Compared with the related art, the utility model has the following beneficial effects:

[0021] 1. In the utility model, by setting a movable component and changing the position of the support column, the position of the support roller inside the drying box is changed, so that the length of the electrode attached to the outer surface of the support roller is changed, so that a longer electrode can be placed inside the drying box, without using a longer drying box, saving space and resources during drying.

[0022] 2.

[0029] Embodiment 1, by Figure 1-3 Provided is a pole piece drying device capable of uniform heating, comprising:

[0030] A drying assembly 1, comprising a drying box 11;

[0031] A movable assembly 2, the movable assembly 2 comprising support columns 21 passing through the positions on both sides of the drying box 11, support rollers 22 connected to the inner side surfaces of the support columns 21, fixing bolts 23 connected to the outer surface positions of the support columns 21, limit blocks 24 connected to the outer side surfaces of the support columns 21, support plates 25 connected to the inner positions on both sides of the drying box 11, telescopic springs 26 connected to the inner positions on both sides of the drying box 11, and a movable plate 27 connected to the outer end positions of the telescopic springs 26;

[0033] The outer surface of the support column 21 has a threaded structure corresponding to the fixing bolt 23, and the support column 21 is located inside the second through hole 15;

[0034] The support plate 25 and the movable plate 27 are located at two end positions inside the second through hole 15, and the outer end of the movable plate 27 and the telescopic spring 26 are located inside the support plate 25;

[0035] Working principle: when it is necessary to place a longer electrode piece inside the drying box 11, screw the fixing bolts 23 outward to make the support column 21 move up and down on both sides of the drying box 11 respectively. When the support column 21 moves to the outer ends of both sides of the drying box 11, screw the fixing bolts 23 inward to fix the support column 21 on both sides of the drying box 11. At this time, the electrode piece is placed in an S shape on the outer surface of the support roller 22 to place a longer electrode piece. At the same time, when the support column 21 moves, it drives the movable plate 27 to move. At this time, one group of movable plates 27 moves downward to drive the telescopic spring 26 to be compressed, and the other group of movable plates 27 moves downward under the action of the telescopic spring 26, so that the outer ends of the two groups of movable plates 27 are always in contact with the outer surface of the support column 21, and the second through hole 15 is blocked by the support plate 25 and the movable plate 27 to avoid heat loss inside the drying box 11.
