Technical Field

[0001] The utility model relates to the technical field of silicon core cutting equipment, and particularly relates to a roller structure with adjustable width connection. Background Art

[0002] In the field of semiconductor material processing, the silicon core is a key component, and its production quality and efficiency directly affect the performance and cost of subsequent products. With the continuous progress of technology, the specifications and sizes of silicon cores are becoming increasingly diverse, which puts higher requirements on silicon core cutting equipment. Traditional silicon core cutting machines usually adopt a roller structure with a fixed width. This structure is unable to cope with the cutting tasks of silicon cores with different diameters, not only restricting the cutting flexibility, but also possibly leading to a decline in cutting accuracy and material waste.

[0003] In order to overcome the above technical defects, various attempts have emerged in the market. For example, replacing rollers with different specifications to adapt to silicon cores with different diameters. However, this method not only increases the complexity and cost of equipment maintenance, but also prolongs the production preparation time and reduces the production efficiency. In addition, frequent replacement of rollers may also cause increased equipment wear, further increasing the difficulty and cost of equipment maintenance. Summary of the Utility Model

[0004] In order to solve the above problems, the embodiment of the utility model provides a roller structure with adjustable width connection that can meet the cutting of silicon cores with different specifications without purchasing new rollers.

[0005] The embodiment of the utility model specifically adopts the following technical solutions to achieve the above purpose: a roller structure with adjustable width connection, including a roller body. An extension part detachably connected to the roller body is provided at the end of the roller body. The extension part includes a support body. A roller extension body is provided on the outer side wall of the support body. One end of the support body is connected to the roller body.

[0006] As a further improvement of the above technical solution:

[0007] The support body includes an extension sleeve. A positioning plate is provided at one end of the extension sleeve. A fastening bolt for connecting the roller body is provided on the positioning plate. A threaded hole corresponding to the position of the fastening bolt is provided on the roller body.

[0008] A clearance hole is provided in the middle of the positioning plate. The clearance hole is coaxially distributed with the extension sleeve.

[0009] The roller body includes an aluminum wheel. A roller base body is provided outside the aluminum wheel. A wire groove is provided on the roller base body.

[0010] The number of the roller extension bodies is two and they are respectively located at both ends of the roller body.

[0011] The support body is selected as an extension rod. One end of the extension rod is provided with a fixing plate for connecting the roller body, and the other end is provided with a plug. The roller extension body is located between the fixing plate and the plug.

[0012] The roller extension body includes a substrate, and a through hole is provided in the middle of the substrate.

[0013] A limiting groove is provided on the side wall of the extension rod, and a limiting convex rib for cooperating with the limiting convex rib is provided at the edge of the through hole.

[0014] The beneficial effects of the embodiment of the present invention are as follows: 1. The roller structure with adjustable width connection includes a roller body, and an extension part detachably connected to the roller body is provided at the end of the roller body. The width of the roller body can be extended by using the extension part, and products with a larger diameter can be cut when cutting silicon cores. The extension part includes a support body, and a roller extension body is provided on the outer side wall of the support body. One end of the support body is connected to the roller body.
