Description

Technical Field

[0001] This utility model relates to a machining technology, and in particular to a roller used in the processing of square silicon rods, specifically a waterproof roller used in the processing of square silicon rods. Background Technology

[0002] Currently, silicon rods are an essential raw material for solar panels. According to the manufacturing process of solar panels, rectangular silicon rods require grinding on all four sides and trimming and rounding of all four edges before slicing. Traditional horizontal grinding machines use a series grinding method: loading, rough grinding, and fine grinding. These three stations cannot work simultaneously. When the silicon rod is being loaded, rough and fine grinding are waiting; when rough grinding is working, fine grinding is waiting; and when fine grinding is working, other stations are waiting, resulting in low processing efficiency. If chamfering / rounding equipment is added, at least two or three machines are needed to meet the requirements of slicing. This increase in equipment quantity inevitably leads to increased procurement costs, installation space costs, and operating labor costs. To address this issue, Chinese Patent Application No. 2023101502023, entitled "A Method and Apparatus for Improving the Processing Efficiency of Rectangular Silicon Rods," has solved the problem relatively well. However, the applicant found that the rollers used extensively in this patent have poor waterproof performance and the bearings are prone to corrosion, which affects the rolling performance, transmission performance, and processing efficiency, and may even lead to transmission errors. Therefore, improvements are necessary. Utility Model Content

[0003] The purpose of this invention is to address the problem of work errors caused by poor waterproof performance of rollers during the processing of square silicon rods, and to design a waterproof roller for use in the processing of square silicon rods.

[0004] The technical solution of this utility model is:

[0005] A waterproof roller used in the processing of square silicon rods includes a wheel body 1 and a roller shaft 2. The wheel body 1 is mounted on the roller shaft 2 via a bearing 3. The roller is characterized in that waterproof covers 4 are installed on both sides of the bearing 3.

[0006] The waterproof cover 4 is fixedly connected to the side of the wheel body 1 by screws. An O-ring seal 5 and a skeleton oil seal 6 are installed on the annular surface of the waterproof cover 4 that contacts the roller shaft 2, so as to prevent water from entering the bearing 3 through double sealing.

[0007] Both the O-ring seal 5 and the skeleton oil seal 6 are wear-resistant seals.

[0008] The beneficial effects of this utility model are:

[0009] This utility model has a simple structure and is easy to manufacture, install and use.

[0010] This invention enhances the waterproof function of the bearing by installing it in the middle and adding waterproof caps and sealing rings at both ends. This makes the bearing more durable in harsh environments and increases its average service life by more than 2 times. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1-4 As shown.

[0017] A waterproof roller used in the processing of square silicon rods has a three-dimensional structure as follows: Figure 4 As shown, its front and side views are as follows: Figure 1 , 2 As shown, the waterproof roller of this utility model includes a wheel body 1 and a roller shaft 2, as follows: Figure 3 As shown, the wheel body 1 is mounted on the roller shaft 2 via the bearing 3. Waterproof covers 4 are installed on both sides of the bearing 3. The waterproof covers 4 are fixedly connected to the side of the wheel body 1 by screws. Wear-resistant O-ring seals 5 and skeleton oil seals 6 (i.e., oil seals with skeletons) are installed on the annular surface where the waterproof cover 4 contacts the roller shaft 2. The double seal prevents water from entering the bearing 3.

[0018] The parts not covered in this utility model are the same as or can be implemented using existing technologies.
