Description

Technical Field

[0001] This application belongs to the field of grinding wheel packaging technology, and in particular relates to a CBN grinding wheel packaging box. Background Technology

[0002] CBN grinding wheels are grinding tools used in the manufacturing of high-end equipment.

[0041] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0042] This embodiment provides a CBN grinding wheel packaging box, such as Figure 1 , Figure 2 As shown, it includes: a packaging box body 1 and a protective layer housed inside the packaging box body 1. The protective layer includes: an outer protective layer 2, an isolation buffer layer 3, and an inner fixing layer 4. The isolation buffer layer 3 covers the sidewall of the inner fixing layer 4, the outer protective layer 2 fills the space between the isolation buffer layer 3 and the inner wall of the packaging box body 1, and the inner fixing layer 4 has a cavity capable of accommodating a CBN grinding wheel 6.

[0043] The protective layer further includes a sealing component 5, which is used to seal the gap at the end face between the isolation buffer layer 3 and the inner fixing layer 4, and / or seal the gap at the end face between the outer protective layer 2 and the isolation buffer layer 3.

[0044] The CBN grinding wheel packaging box provided in this embodiment, from the inside out, uses an internal fixing layer 4 to conveniently accommodate the CBN grinding wheel while limiting excessive shaking of the CBN grinding wheel. The isolation buffer layer 3 reduces the impact or shock on the packaging box during transportation. The external protective layer 2 makes the packaging box less prone to deformation under force and has a certain impact resistance. The packaging box body 1 serves to shape and protect the protective layer. The sealing component 5 blocks dust or moisture that may enter the gap between the isolation buffer layer 3 and the internal fixing layer 4, preventing dust or moisture from spreading inside the protective layer and ultimately corroding the CBN grinding wheel contained therein. Under the combined effect, the CBN grinding wheel is not easily subjected to severe impacts, squeezing and other external forces during transportation, and can also prevent the CBN grinding wheel from being corroded by dust and moisture, significantly reducing the risk of grinding wheel damage during transportation, storage and other processes.

[0045] The packaging box provided in this embodiment achieves its function in the following ways:

[0046] 1. For example Figure 1 As shown, the cavity of the internal fixing layer 4 restricts excessive shaking of the CBN grinding wheel, ensuring that the CBN grinding wheel 6 will not shift or tilt from the containment space when the packaging box shakes, so that the position of the CBN grinding wheel 6 inside the packaging box is controllable, and the theoretical effect of the entire protective layer can be performed normally.

[0047] 2. The isolation buffer layer 3 allows the CBN grinding wheel 6 to dissipate kinetic energy through slight displacement after being impacted. After the impact dissipates, it can return to its central position through the rebound of the isolation buffer layer 3. This effectively absorbs and disperses the impact force, further protecting the grinding wheel.

[0048] 3. The outer protective layer 2 makes the outer part of the packaging box less susceptible to deformation under stress, ensuring that the packaging box as a whole is not prone to tilting or deformation during transportation, and ensuring that the theoretical function of the protective layer is properly performed. At the same time, the outer protective layer 2 has a certain impact resistance and plays an auxiliary cushioning role.

[0049] 4. The packaging box 1 serves to shape and protect the packaging layer.

[0050] 5. The function of the sealing component 5 is to block dust or moisture that may enter the gap between the isolation buffer layer 3 and the inner fixing layer 4, and to prevent dust or moisture from spreading inside the protective layer and eventually eroding the CBN grinding wheel 6 contained therein.

[0051] In summary, the packaging box provided in this embodiment offers comprehensive and multi-layered protection for the CBN grinding wheel 6.

[0052] In an alternative embodiment, such as Figures 1-4 As shown, the internal fixing layer 4 includes an upper protective layer 100 and a lower protective layer 200, with the upper protective layer 100 covering the lower protective layer 200. The upper protective layer 100 and the lower protective layer 200 each have an embedding groove 40 at their opposite end faces for at least partial embedding of the CBN grinding wheel 6. The cavity formed by the embedding grooves 40 of the upper protective layer 100 and the lower protective layer 200 can accommodate the CBN grinding wheel 6. The embedding groove 40 of the upper protective layer 100 and the lower protective layer 200 can accommodate the CBN grinding wheel 6, allowing it to be embedded within the cavity. The embedding groove 40 restricts excessive shaking of the CBN grinding wheel, ensuring that the CBN grinding wheel 6 will not shift or tilt from the accommodating space when the packaging box shakes.

[0053] The isolation buffer layer 3 covers the sidewall of the inner fixing layer 4, and the isolation buffer layer 3 is made of a foam material with elastic recovery properties. The use of an elastic recovery foam material in the isolation buffer layer 3 allows the CBN grinding wheel 6 to dissipate kinetic energy through slight displacement after being impacted. After the impact dissipates, it returns to its central position through the rebound of the isolation buffer layer 3. This effectively absorbs and disperses the impact force, further protecting the grinding wheel.

[0054] The outer protective layer 2 is filled between the isolation buffer layer 3 and the inner wall of the packaging box 1. The outer protective layer 2 is made of a foam material with toughness and impact resistance. This makes the outer part of the packaging box less prone to deformation under stress, ensuring that the packaging box as a whole is not prone to tilting or deformation during transportation, and ensuring that the theoretical function of the protective layer is properly performed. At the same time, the outer protective layer 2 has a certain impact resistance, playing an auxiliary cushioning role.

[0055] In an optional embodiment, the foam material with elastic recovery properties includes a slow-rebound foam material. This material has the physical property of rapid deformation and slow rebound, enabling it to quickly dissipate kinetic energy upon impact and then slowly rebound to push the CBN grinding wheel 6 back to its original position, producing a good energy absorption effect. Optionally, this embodiment uses MDI material (methylene diphenyl diisocyanate) supplied by Wanhua Chemical.

[0056] In an optional embodiment, the foam material with toughness and impact resistance includes a high-hardness foam material. This material possesses physical properties such as efficient cushioning, self-adaptive encapsulation, and fatigue resistance, and can essentially maintain its shape after repeated deformation, making it an effective outer layer for protection. Optionally, this embodiment uses PU (polyurethane) material supplied by Wanhua Chemical.

[0057] In an optional embodiment, the inner fixing layer 4 is made of the same material as the outer protective layer 2 to facilitate the actual production and procurement of materials and reduce production costs.

[0058] In an alternative embodiment, such as Figure 4 As shown, the embedding groove 40 includes: a first recessed area 41, a raised area 42, and a second recessed area 43.

[0059] A first recessed area 41 is located at the center of the embedding groove 40 and is used for embedding the center portion 61 of the CBN grinding wheel 6; a raised area 42 is located radially outside the first recessed area 41 and is used to support the main body portion 62 of the CBN grinding wheel 6; a second recessed area 43 is located radially outside the raised area 42 and is used for embedding the edge portion 63 of the CBN grinding wheel 6.

[0060] like Figure 3 As shown, this embodiment uses a circular CBN grinding wheel 6 as an example. The CBN grinding wheel 6 includes, from the inside out: a center portion 61, a main body portion 62, and an edge portion 63. The center portion 61 and the edge portion 63 protrude axially relative to the main body portion 62, while the main body portion 62 is axially recessed relative to the center portion 61 and the edge portion 63. The first recessed area 41, the protruding area 42, and the second recessed area 43 of this embodiment can well match the structural features of the CBN grinding wheel 6, providing sufficient support and enclosure, which is beneficial for fully limiting the position of the CBN grinding wheel 6 inside and preventing it from shifting due to bumps during transportation.

[0061] In an optional embodiment, the inner wall of the embedding groove 40 is adhered to or coated with an anti-slip layer. In this embodiment, the anti-slip layer can increase the friction with the CBN grinding wheel 6, further preventing the CBN grinding wheel 6 from shifting in the embedding groove 40.

[0062] In an optional embodiment, the packaging box 1 and the outer protective layer 2, the outer protective layer 2 and the isolation buffer layer 3, and / or the isolation buffer layer 3 and the inner fixing layer 4 are bonded together by hot pressing or by adhesive bonding, so that the layers are tightly bonded together to prevent dust and moisture from entering.

[0063] In an alternative embodiment, such as Figure 1 As shown, the packaging box 1 includes a bottom plate 13, a top cover 12, and side plates 11. The side plates 11 surround the outer side of the outer protective layer 2. The bottom plate 13 is connected to the lower end of the side plates 11 and is used to support the bottom of the protective layer. The top cover 12 is connected to the upper end of the side plates 11 and is used to abut against the top of the protective layer. In this embodiment, the packaging box 1 wraps and protects the four sides, top, and bottom of the protective layer through the bottom plate 13, top cover 12, and side plates 11, ensuring that the outer surface of the protective layer is not easily affected by external factors in any direction.

[0064] In an optional embodiment, the top cover 12 is detachably or movably connected to the upper end of the side plate 11. In this embodiment, the top cover 12 is easy to open or close so that the upper protective layer 100 can be inserted or removed from the top opening of the packaging box 1, and the CBN grinding wheel 6 inside can be easily inserted or removed.

[0065] In an alternative embodiment, such as Figure 1 , Figure 2 As shown, the sealing component 5 includes waterproof tape, which seals the gap at the end face between the isolation buffer layer 3 and the inner fixing layer 4. In this embodiment, since the upper protective layer 100 of the inner fixing layer 4 is used to be inserted or removed from the top opening of the packaging box 1, the gap at the end face between the isolation buffer layer 3 and the inner fixing layer 4 is relatively obvious, which is the place where dust and moisture are most likely to penetrate. Covering this position with waterproof tape can effectively reduce the risk of corrosion inside the protective layer.

[0066] In an alternative embodiment, such as Figure 1 As shown, the waterproof tape is adhered to the top surface of the upper protective layer 100 and covers the gap between the isolation buffer layer 3 and the inner fixing layer 4. In this embodiment, the waterproof tape covers the gap between the isolation buffer layer 3 and the inner fixing layer 4 at the top surface of the upper protective layer 100. Since this location is adjacent to the top cover 12, it is most prone to dust or moisture leakage. Sealing this location in this embodiment can significantly reduce the risk of corrosion of the CBN grinding wheel 6.

[0067] This embodiment provides an assembly method for the above-mentioned CBN grinding wheel packaging box, including the following steps: First, a mold for the inner fixing layer 4 is made according to the specific size and shape of the required CBN grinding wheel 6. Foaming material is injected into the mold to form an embedding groove 40 that matches the shape and size of the required CBN grinding wheel 6. Then, the foaming material of the isolation buffer layer 3 is cut into a suitable shape and size and covered on the inner fixing layer 4. Next, the outer protective layer 2 is wrapped around the outermost layer, and the layers are tightly bonded together by hot pressing or adhesive bonding. Finally, the required CBN grinding wheel 6 is placed into the embedding groove 40 of the inner fixing layer 4. After the assembly of the protective layer is completed, the entire protective layer is inserted into the packaging box body 1, and the packaging is sealed and fixed using a sealing packaging assembly. Example

[0068] like Figure 5 As shown, in this embodiment, the sealing component 5 includes waterproof tape. The waterproof tape is adhered to the end face of the upper protective layer 100 or the lower protective layer 200, and the waterproof tape seals the gap at the end face between the isolation buffer layer 3 and the outer protective layer 2. In this embodiment, considering that dust or moisture may also seep into the gap at the end face between the isolation buffer layer 3 and the outer protective layer 2, waterproof tape is used for sealing. Example

[0069] like Figure 6 As shown, in this embodiment, the sealing component 5 includes waterproof tape, which is adhered to the end face of the upper protective layer 100 or the lower protective layer 200. The waterproof tape seals the gaps at the end faces between the isolation buffer layer 3 and the outer protective layer 2, as well as between the isolation buffer layer 3 and the inner fixing layer 4. In this embodiment, a relatively wide waterproof tape is used to simultaneously cover and seal the gaps at the end faces between the isolation buffer layer 3 and the outer protective layer 2, as well as between the isolation buffer layer 3 and the inner fixing layer 4, significantly reducing the risk of dust or moisture seeping between the layers.

The technical scope of this application is not limited to the contents of the specification, but must be determined according to the scope of the claims.
