Description

Technical Field

[0001] This utility model relates to the technical field of single-crystal silicon rod manufacturing, and in particular to a graphite foil cutting and storage device. Background Technology

[0002] In the monocrystalline silicon rod manufacturing industry, it is common practice to use graphite foil as a gap-filling material between the crucible base, crucible support, and crucible. This measure aims to prevent the quartz crucible from becoming difficult to disassemble after prolonged use due to adhesion to the crucible base and support. However, in practice, the use of graphite foil must follow the principle of on-site cutting and use, that is, it should be cut into circles of different diameters according to specific needs, while retaining necessary slits to ensure its applicability.

[0003] Current processing methods for graphite foil face the problem of low replacement efficiency in large-scale applications. Due to the cuts created during processing, coupled with the inherent brittleness of graphite foil, it is easily damaged during transportation and replacement. This situation hinders the formation of a complete, uninterrupted surface for the graphite foil in applications, and consequently creates unwanted gaps in the assembly process, particularly in the combination of the crucible support, crucible base, and crucible. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a graphite foil cutting and storage device that is easy to store, avoids pollution, is easy to take out and easy to cut.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes an outer box and an inner box. The outer box is provided with a receiving cavity. The outer box has a cutting hole and an opening. The cutting hole and the opening are both connected to the receiving cavity. The inner box is rotatably connected in the receiving cavity and cooperates with the opening. The cutting hole is adapted to a cutting knife.

[0006] Furthermore, a limiting baffle is provided on the inner box, and the limiting baffle is blocked by the outer box when the inner box rotates to close the opening.

[0007] Furthermore, the limiting baffle is located inside the inner box and extends out of the outer side of the inner box.

[0008] Furthermore, the inner box includes a chassis and a box body, with the box body disposed on the chassis.

[0009] Furthermore, the inner box is equipped with a rotating handle.

[0010] Furthermore, the outer box has a through hole, and the rotating handle extends from the bottom up through the through hole.

[0011] Furthermore, the through hole is connected to the cutting hole.

[0012] Furthermore, the cutting holes are located on the outer side and the upper surface of the outer box.

[0013] Furthermore, a rotating block is provided in the receiving cavity, and a slot is provided at the bottom of the inner box, with the rotating block cooperating with the slot.

[0014] Furthermore, the cross-section of the graphite foil cutting and storage device is circular.

[0015] The beneficial effects of this utility model are:

[0016] In contrast to the shortcomings of existing technologies, this invention specifically addresses the issue by rotating the inner box to open the opening and place graphite foil into the receiving cavity. Further rotation of the inner box closes the opening, achieving storage. With the graphite foil stored in the receiving cavity and the opening closed, a cutting tool can be inserted into the cutting hole to cut the graphite foil within the receiving cavity. Therefore, the graphite foil cutting and storage device can safely store graphite foil, effectively preventing contamination of the cut graphite foil, and is easy to carry to the field for immediate use. This effectively reduces the risk of graphite foil breakage during transportation, ensuring the safety and integrity of the material. Furthermore, it allows for cutting the carbon foil edges within the receiving cavity for assembly and use. Thus, this invention offers advantages such as easy storage, prevention of contamination, easy retrieval, and easy cutting. Attached Figure Description
