Description

Technical Field

[0001] The utility model relates to the technical field of ceramic roller conveying equipment, in particular to a novel ceramic roller. Background Art

[0002] Solar cell sintering furnace is a kind of equipment used to manufacture solar cells. Generally, mesh belt sintering furnace is used to transfer solar cell sheets from the drying section head to the cooling section tail of the sintering furnace. With the rapid development of photovoltaic industry, the disadvantages of mesh belt sintering furnace are becoming more and more obvious. High purity ceramic rollers have gradually replaced stainless steel mesh belts to transfer solar cell sheets.

[0003] There are at least the following problems in the prior art: first, ceramic rollers are very easy to break and be damaged during assembly, installation, transportation, and use, which will invisibly increase production costs; second, if the ceramic roller breaks during use, it needs to be stopped and replaced, which not only increases maintenance costs but also reduces production efficiency. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and develops a novel ceramic roller. The utility model can reduce the situation of roller breakage and the downtime caused by roller breakage, thereby effectively reducing production costs and improving production efficiency.

[0005] The technical solution of the utility model for solving the technical problem is: a novel ceramic roller comprises a roller body, and an inner support body is arranged inside the roller body.

[0006] As an optimization, the inner support body is a columnar support body.

[0007] As an optimization, the inner support body is a tubular support body.

[0008] As an optimization, an opening is provided on the inner support body, and the cross-section of the inner support body is "C"-shaped, which can improve the flexibility of the inner support body so that the side walls on both sides of the opening can bend inward to a certain extent, making it easier to insert the inner support body into the roller body.

[0009] As an optimization, a plurality of groups of long grooves are provided through the inner support body, and the long grooves are distributed along the circumference of the inner support body, which can further improve the flexibility of the inner support body and facilitate the insertion of the roller body.

[0010] As an optimization, a limiting hole is provided on the inner support body, and a positioning hole corresponding to the limiting hole is provided on the roller body. The positioning hole is connected to the limiting hole through a connecting column, which can effectively connect the roller body and the inner support body, limit the inner support body, prevent the inner support body from radially shaking in the roller body, and facilitate installation, disassembly and maintenance.

[0011] As an optimization, the limiting hole is any one of an oblong hole, a round hole, a square hole and an oblong hole. When the limiting hole is an oblong hole or an oblong hole, the inner support body can rock in the roller body along the axial direction.

[0012] As an optimization, at least one group of inner support bodies is provided.

[0013] As an optimization, at least one set of limiting holes is provided on the inner support body.

[0014] As an optimization, the roller body is made of ceramic, and the inner support body is made of any one of stainless steel and carbon steel.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The inner support body can support the roller body from the inside to the outside, greatly reducing the situation of roller breakage and downtime caused by broken rollers. Even if the ceramic roller breaks during use, the roller body can still maintain normal operation under the action of the inner support body, and the vibration of the broken roller is kept within a normal range without affecting production operations until the staff performs maintenance and replacement. The utility model can reduce the situation of broken rollers and the downtime caused by broken rollers, effectively reducing production costs and improving production efficiency.

[0022] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0023] Example 1

[0024] Figures 1 to 4 An embodiment of the present utility model is as follows: Figure 1 and Figure 4As shown, a new type of ceramic roller includes a roller body 1, which is ceramic. A mounting cavity is provided inside the roller body 1, and an inner support body 2 is provided inside the mounting cavity. The inner support body 2 is any one of a tubular support body or a columnar support body. The inner support body 2 is any one of stainless steel and carbon steel. The roller body 1 is connected to the inner support body 2 through a connecting column 3. The inner support body 2 can support the roller body 1 from the inside to the outside, which greatly reduces the situation where the roller body 1 breaks and the roller breaks and causes shutdown. Even if the ceramic roller breaks during use, the roller body 1 can still maintain normal operation under the action of the inner support body 2, and keep the vibration of the broken roller within a normal range without affecting the production operation until the staff performs maintenance and replacement.

[0025] like Figure 2 and Figure 4 As shown, at least one group of limiting holes 22 is provided on the inner support body 2, and the limiting holes 22 are oblong holes. The roller body 1 is provided with positioning holes 11 corresponding to the limiting holes 22. The positioning holes 11 are connected to the limiting holes 22 through connecting columns 3, which can effectively connect the roller body 1 and the inner support body 2, and can limit the inner support body 2 to prevent the inner support body 2 from radially shaking in the roller body 1, and are convenient for installation, disassembly and maintenance.

[0026] like Figures 2 to 4 As shown, the inner support body 2 is a tubular support body, and an opening 21 is provided on the inner support body 2. The cross section of the inner support body 2 is "C"-shaped, which can improve the flexibility of the inner support body 2, so that the side walls on both sides of the opening 21 can bend inward to a certain extent, and it is convenient to insert the inner support body 2 into the roller body 1. After the inner support body 2 is inserted into the roller body 1, due to the tension effect of the "C"-shaped cross section, the inner support body 2 can be tightly attached to the inner cavity of the roller body 1, thereby supporting the roller body 1.

[0027] like Figure 4 As shown, the inner support body 2 is a tubular support body, and a plurality of groups of long grooves 23 are provided through the inner support body 2. The long grooves 23 are distributed along the circumference of the inner support body 2, which can further improve the flexibility of the inner support body 2, facilitate the insertion of the roller body 1 and support the roller body 1, and the inner support body 2 is provided with at least one group.

[0028] During use, several groups of the new ceramic rollers are installed on the frame through the installation components to form a new ceramic roller table to replace the stainless steel mesh belt to transport solar cells. This can effectively reduce the downtime caused by ceramic roller breakage and roller interruption during operation. Even if the roller body 1 breaks during use, the roller body 1 can still maintain normal operation under the action of the internal support body 2, so that the vibration of the broken roller is within the normal range and does not affect production and operation until the staff performs maintenance and replacement. This can greatly improve production efficiency and reduce production costs.

[0029] The descriptions of the orientation or relative position relationship of the structure in the present invention, such as the orientation or relative position relationship indicated by "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
