Description

Technical Field

[0001] This utility model relates to the field of hard carbon negative electrode processing technology, and in particular to a roller oven for drying hard carbon negative electrode sheets. Background Technology

[0002] Roller ovens are specialized drying equipment used in the preparation of lithium-ion battery electrodes. They are mainly used for continuous and efficient drying of coated hard carbon negative electrode sheets. The core structure is a production line device consisting of conveyor rollers, a heating system, a temperature control system, and an exhaust system. The negative electrode sheets are continuously conveyed through the rollers, and the moisture and solvent are evaporated and removed in the oven, which can meet the needs of large-scale mass production.

[0003] The existing roller drying ovens for drying hard carbon negative electrodes have the following shortcomings: Currently, due to their thin and light material, hard carbon negative electrodes are prone to deviation during roller conveying. The edges and corners of the deviated negative electrodes are prone to collision with the roller conveyor, which may not only cause damage to the edges and corners, but also cause the electrode to be squeezed and deformed due to the external force generated by the collision, thus destroying its structural integrity.

[0004] Therefore, a roller oven for drying hard carbon negative electrode sheets is needed to solve the above problems. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems of the roller drying oven for drying hard carbon negative electrode sheets mentioned above, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a roller oven for drying hard carbon negative electrode sheets, which solves the problem that hard carbon negative electrode sheets are prone to deviation during roller conveying, resulting in collisions with the rollers. This can not only cause damage to the edges and corners, but also cause the electrode sheets to be squeezed and deformed due to the external force generated by the collision, thus destroying their structural integrity.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a roller drying oven for drying hard carbon negative electrode sheets, comprising a roller drying device and a conveying mechanism disposed inside the roller drying device, including:

[0009] A limiting component is disposed on the top of the conveying mechanism, and the limiting component includes a limiting mesh plate, a movable rod, and a drive motor;

[0013] In a preferred embodiment of the roller oven for drying hard carbon negative electrode sheets according to this utility model, a stabilizing element is fixedly connected to the top of the conveying mechanism, and the movable rod is slidably connected between the stabilizing elements.

[0014] In a preferred embodiment of the roller oven for drying hard carbon negative electrode sheets according to this utility model, a protective seat is fixedly connected to the bottom of the conveying mechanism, and a connecting member is fixedly connected to the side wall of the movable rod, the connecting member passing through both sides of the protective seat.

[0015] In a preferred embodiment of the roller oven for drying hard carbon negative electrode sheets according to the present invention, a rack is fixedly connected to the end of the connector, and the rack is slidably connected inside the protective seat.

[0016] As a preferred embodiment of the roller oven for drying hard carbon negative electrode sheets according to this utility model, the protective seat is internally rotatably connected with gears, the tooth surfaces of two sets of racks correspond to each other, and the gears mesh with the racks.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention.

[0029] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale.

[0030] Example 1

[0031] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a roller drying oven for drying hard carbon negative electrode sheets, which can achieve the effect of stable moving and drying of hard carbon negative electrode sheets. It includes a roller drying device 100 and a conveying mechanism 101 disposed inside the roller drying device 100, including:

[0032] Limiting component 200 is disposed on the top of conveying mechanism 101. Limiting component 200 includes limiting mesh plate 201, movable rod 202 and drive motor 209.

[0033] The limiting mesh plate 201 is located at the top of the conveying mechanism 101 and is used to limit the hard carbon negative electrode sheet. The movable rod 202 and the drive motor 209 are located at the bottom of the conveying mechanism 101 and are used to move the limiting mesh plate 201.

[0034] In use, the two sets of limiting screen plates 201 can be moved towards each other by the drive motor 209, which makes it easy to adjust the distance between the two sets of limiting screen plates 201 according to the size of the hard carbon negative electrode sheet. At this time, the hard carbon negative electrode sheet can be placed on the conveying mechanism 101 in sequence, and then transported to the inside of the roller drying equipment 100 for drying. This avoids the hard carbon negative electrode sheet from shifting during transportation, which would cause the corners of the negative electrode sheet to collide with the rollers on the conveying mechanism 101, thus improving the stability of the hard carbon negative electrode sheet during movement and drying.

[0035] Example 2

[0036] Reference Figures 1 to 5 This is the second embodiment of the present invention. Unlike the previous embodiment, the movable rod 202 is fixedly connected to the side wall of the limiting mesh plate 201, and the two sets of limiting mesh plates 201 are symmetrically distributed.

[0037] Among them, silicone strips 201a are fixedly connected to one side of each of the two sets of limiting mesh plates 201. By setting high temperature resistant silicone strips 201a, the hard carbon negative electrode sheet is prevented from directly colliding with the roller conveyor, which can easily cause wear on the hard carbon negative electrode sheet.

[0038] The top of the conveying mechanism 101 is fixedly connected to a stabilizer 203, and the movable rod 202 is slidably connected between the stabilizers 203. The stabilizers 203 improve the stability of the movable rod 202 when it moves.

[0039] The bottom of the conveying mechanism 101 is fixedly connected to a protective seat 207, and the side wall of the movable rod 202 is fixedly connected to a connector 204, which passes through both sides of the protective seat 207.

[0040] The connector 204 has a rack 205 fixedly connected to its end. The rack 205 is slidably connected inside the protective base 207. The protective base 207 has a gear 206 rotatably connected inside. The tooth surfaces of the two sets of racks 205 correspond to each other. The gear 206 meshes with the rack 205. By rotating the gear 206, the two sets of racks 205 can be driven to move towards each other. At the same time, the racks 205 can drive the two sets of movable rods 202 and the limiting mesh plate 201 to move. This makes it easy to adjust the distance between the two sets of limiting mesh plates 201 according to the size of different hard carbon negative electrode sheets, thus improving its applicability.

[0041] The drive motor 209 is fixedly installed at the bottom of the conveying mechanism 101. The output end of the drive motor 209 is fixedly connected to the shaft 208, and the gears 206 are fixedly connected to both ends of the shaft 208. The drive motor 209 can drive the shaft 208 to rotate, and the shaft 208 can drive the two sets of gears 206 at both ends to rotate.

[0042] In use, firstly, according to the size of the hard carbon negative electrode sheet, the drive motor 209 drives the shaft 208 to rotate. At the same time, the shaft 208 can drive the two sets of gears 206 at both ends to rotate. Then, through the rotating gears 206, the two sets of racks 205 and the limiting mesh plate 201 are driven to move towards each other until the distance between the two sets of limiting mesh plates 201 is suitable for the size of the hard carbon negative electrode sheet. Finally, the roller drying equipment 100 and the conveying mechanism 101 are driven, and the hard carbon negative electrode sheet is placed on the conveying mechanism 101 in sequence, so that it can be transported into the inside of the roller drying equipment 100 for drying.

[0043] It is worth noting that the aforementioned drive motor 209 is a commonly used controller device, which belongs to existing mature technology. Its electrical connection relationship and specific circuit structure will not be described in detail here. The specific functions and operating principles of the aforementioned roller drying equipment 100 and conveying mechanism 101 can be referred to the four-row single-layer nitrogen roller furnace equipment of Suzhou Keen New Energy Technology Co., Ltd.

[0044] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
