Description

Technical Field

[0001] The utility model mainly relates to the technical field of conductive rollers, in particular to a novel conductive roller. Background Art

[0002] A conductive roller refers to a roller that can conduct electric current and is mainly used in the preparation of electrode sheets. When the electrode sheets are coated with positive electrode materials, negative electrode materials and conductive agents, the conductive roller conducts current to make the coating on the surface of the electrode sheets uniform and ensure that the coating area is sufficient to cover the entire electrode sheet. In addition, the conductive roller can also help the electrode sheets reach the ideal size and shape during the cutting and winding process.

[0003] The surface of the conductive roller is usually sprayed or electroplated with a layer of silver to improve its conductive properties. During the charge transfer process, the silver-plated conductive roller can more effectively reduce energy loss and improve transmission efficiency due to the high conductivity of silver. The conductive roller may encounter various corrosive media such as acid and alkali during use. The silver layer can effectively prevent oxidation and corrosion, thereby extending the service life of the conductive roller. However, the silver layer will be worn out after long-term use and needs to be re-sprayed with silver. The conductive roller is generally made of metal and has a heavy overall weight, so spraying it is labor-intensive. Utility Model Content

[0023] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0024] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "provided with", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0027] See attached Figure 1-3 , a new conductive roller, comprising:

[0028] Conductive roller body 1;

[0029] A conductive sleeve 2, wherein the conductive sleeve 2 is sleeved on the conductive roller body 1 and a silver coating 3 of a predetermined thickness is sprayed on the surface of the conductive sleeve;

[0030] The nut sleeves 4 are two in number and are threadedly connected to the conductive roller body 1 , and the opposite ends thereof are respectively abutted against the two ends of the conductive sleeve 2 .

[0031] In this embodiment, after the conductive sleeve 2 is put on the conductive roller body 1, the nut sleeves 4 are assembled on both ends of the conductive roller body 1 until the two nut sleeves 4 are respectively abutted against the two ends of the conductive sleeve 2, and the installation of the conductive sleeve 2 is completed. Similarly, it can be disassembled and the silver coating 3 on its surface can be repaired. Therefore, the repair of the silver coating 3 does not require the disassembly of the entire body, and only the conductive sleeve 2 needs to be disassembled, which has low labor intensity and higher work efficiency.

[0032] The side wall of the nut sleeve 4 is equipped with a plurality of positioning bolts 5 , and the positioning bolts 5 match the positioning holes 101 opened on the surface of the conductive roller body 1 .

[0033] In this embodiment, the conductive sleeve 2 rotates with the conductive roller body 1, and a certain friction force is generated when the silver coating 3 contacts the material for coating. The nut sleeve 4 is threadedly installed on the conductive roller body 1, which may cause the nut sleeve 4 to loosen and fail to limit the conductive sleeve 2. To this end, a number of positioning bolts 5 can be installed on the side wall of the nut sleeve 4, and the positioning bolts 5 are connected to the positioning holes 101 opened on the surface of the conductive roller body 1, so that the nut sleeve 4 can be firmly locked on the conductive roller body 1 to prevent loosening.

[0034] In this embodiment, considering that the device will generate a lot of heat when powered on, which will affect the quality of the coating, the following embodiment is proposed: the conductive roller body 1 has a hollow structure inside, and an air inlet 102 is opened at one end, and a plurality of evenly distributed air outlets 103 are opened on the surface.

[0035] In this embodiment, after the heat dissipation wind is introduced into the air inlet 102 , the wind enters the interior of the conductive roller body 1 , and is discharged through the air outlet 103 , and directly acts on the conductive sleeve 2 , thereby achieving a heat dissipation effect.

[0036] According to the above embodiment, a more preferred embodiment is proposed here: the opening radius of the air inlet 102 decreases from the inside to the outside.

[0037] In this embodiment, air enters from the large opening and exits from the small opening. The outlet air is compressed and the flow rate increases, so more heat is taken away in a short time, thereby improving the heat dissipation effect.

[0038] Finally, the conductive roller body 1 and the conductive sleeve 2 are both made of copper, stainless steel or aluminum.

[0039] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.

[0040] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art.
