Description

Technical Field

[0001] This application relates to the technical field of lithium battery processing equipment. Specifically, it relates to an anti-wear structure for the outer line flipping of a kiln furnace in the lithium battery industry. Background Art

[0002] The cathode material is an important component in the production of lithium-ion batteries. Its production process is complex and involves a large number of equipment. Among them, the flipping of the kiln furnace is an important process in the production process, and the flipping mechanism can meet the required process requirements.

[0003] However, during the production process, in the flipping and discharging process of the existing outer line flipping mechanism of the kiln furnace, the flipping turntable and the flipping main body are in the same plane, and the gap between them is 2-4 mm. The gap allowance is very small. During long-term use and when carrying materials, due to its weight and long-term operation, the mechanism generates structural deformation, causing metal wear due to collision, contact, and friction between the two. The generated metal fine powder enters the normal materials, resulting in unqualified product indicators. To reduce the wear between the two, increasing the gap between them can be considered, but when the gap becomes larger, the dust generated during the flipping process of the materials inside the flipper leaks out from the gap, causing environmental protection problems.

[0004] Therefore, it is necessary for the inventor to design a new anti-wear structure for the outer line flipping of a kiln furnace in the lithium battery industry to overcome the above problems. Summary of the Invention

[0005] The main purpose of this application is to provide an anti-wear structure for the outer line flipping of a kiln furnace in the lithium battery industry to solve the problems of unqualified product data indicators caused by metal wear and dust leakage in the related technology.

[0015] Preferably, a rotating shaft for fixedly connecting with an external motor is arranged through the turntable, and auxiliary support structures are fixedly arranged between both ends of the rotating shaft and the ground.

[0031] Embodiment 1:

[0032] As Figure 1 、 Figure 2As shown in the figure, a wear-resistant structure for the outer line flipping of a kiln in the lithium battery industry includes a flipping machine main body 1 and a flipping mechanism with turntables 2 at both ends. Among them: An opening 3 is provided on the flipping machine main body 1 and is matched with the flipping mechanism, and the plane of the turntable 2 is offset from the plane of the opening 3; A sealing member is fixedly arranged between the opening 3 and the turntable 2.

[0033] Specifically, since the turntable 2 is prone to friction with the side wall of the opening 3 at the opening 3, resulting in metal wear entering the materials in the flipping mechanism, the turntable 2 is offset from the opening 3. It can be that the turntable 2 shrinks inward into the flipping machine main body 1 or is pulled out outward from the flipping machine main body 1. After the two are offset, even if the turntable 2 deforms downward under the gravity of the flipping mechanism and the materials, the edge of the turntable 2 will not contact and rub against the side wall of the opening 3, thus avoiding the situation of wear metal entering the materials. In addition, since the plane of the turntable 2 is offset from the plane of the opening 3, the gap between the two increases accordingly, and the dust of the materials is likely to leak out. Therefore, a sealing member is provided to fill the gap between the two, reducing the leakage of dust. In this embodiment, by offsetting the plane of the turntable 2 from the plane at the opening 3, the edge of the turntable 2 will not rub and cause loss with the side wall of the opening 3 of the flipping machine main body 1, ensuring the quality of the materials. At the same time, a sealing member is provided to prevent the dust of the materials in the flipping mechanism from leaking from the gap between the opening 3 and the turntable 2.

[0034] The turntable 2 is located outside the flipping machine main body 1 and is parallel to the plane of the opening 3. Specifically, the turntable 2 is pulled outwards. Compared with the way of shrinking inwards, it is not only easier to install the sealing member, but also convenient for the staff to observe and maintain the opening 3. Of course, shrinking the turntable 2 inwards so that it is located inside the flipping machine main body 1 also belongs to a technical solution of this technical concept.

[0035] The gap between the turntable 2 and the opening 3 is 0.5 - 1 cm. Specifically, if the gap is too large, the required size of the sealing member is larger, which is not easy to install and has poor sealing performance. If the gap is too small, when the flipping mechanism deforms downward during long-term use, the turntable 2 still has a greater chance of rubbing and wearing against the side wall at the opening 3, and the protection effect on the quality of the materials is insufficient. According to actual experience, it is more appropriate to set the gap size at 0.5 - 1 cm.

[0036] The sealing member includes a sealing rubber ring 4. One end of the sealing rubber ring 4 is fixedly connected to the flipping machine main body 1, and the other end is sleeved on the outer wall of the turntable 2.

[0037] The sealing rubber ring 4 is fixedly connected to the outer wall of the turnover machine main body 1 through glue. Specifically, one end of the sealing rubber ring 4 is adhesively bonded to the outer wall of the turnover main body at the opening 3. When pasting, it should be noted that the inner edge of the sealing rubber ring 4 is flush with the edge of the opening 3 to avoid gaps or corners that can accommodate materials after the rubber ring fits against the outer wall.

[0038] The sealing rubber ring 4 is made of rubber. The rubber material is relatively soft. During the rotation of the turntable 2, the sealing rubber ring 4 can still fit against the outer wall of the turntable 2 to prevent material dust from leaking out.

[0039] A rotating shaft 6 for fixedly connecting to an external motor is disposed through the turntable 2. Auxiliary support structures are fixedly arranged between both ends of the rotating shaft 6 and the ground. The auxiliary support structure includes a telescopic rod 7. The lower end of the telescopic rod 7 is fixedly arranged on the ground, and the top end of the telescopic rod 7 is fixedly provided with an arc-shaped plate 8 that cooperates with the rotating shaft 6. Specifically, in the prior art, the output shaft of the motor is usually directly connected to the rotating shaft 6, resulting in a relatively large torque borne by the distal end of the rotating shaft 6. By providing the telescopic rod 7 to assist in supporting the middle of the rotating shaft 6, the forces on each part of the rotating shaft 6 are made uniform, and the turntable 2 is not easily deformed downward after long-term use, further preventing friction between the turntable 2 and the opening 3. When specifically setting, the telescopic rod 7 can be a cylinder or in the form of a screw and a sleeve, and any device that can perform telescopic support can be used here.

[0040] Embodiment 2: As Figure 3 、 Figure 4 shown, the difference between this embodiment and Embodiment 1 is that: an annular groove 5 for engaging with the side wall of the opening 3 is provided on the outer wall of one end of the sealing rubber ring 4. Specifically, during installation, the annular groove 5 is aligned and connected with the opening 3, and it is fixed at the opening 3 by the elastic force of the sealing rubber ring 4 itself. Compared with Embodiment 1, the sealing rubber ring 4 in this embodiment is more convenient to install, but the sealing rubber ring 4 needs to be customized, and the connection stability is poorer than that of adhesive bonding.

[0041] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
