[0001] This application relates to the field of packaging technology, and in particular to a boxing accessory and packaging box for a coated sheet. Background Technology

[0002] For automotive glass, a coating process is often required during production, primarily involving applying two or three layers of silver film to one side of the glass. Before being shipped out of the factory, coated glass is usually packed in boxes using glass liner paper. Each box contains multiple pieces of coated glass, with adjacent pieces separated by liner paper, the smooth side of which is in contact with the glass coating layer.

[0003] During the process of laying the backing paper, workers pat the paper with their hands to make it flat. However, during this patting process, dust or tiny particles that may be attached to the surface of the backing paper may rub against the coated glass, potentially causing scratches on the coated glass. Utility Model Content

[0004] In view of this, the present application provides a packaging accessory and a packaging box for coated sheet materials to solve at least one problem existing in the background art, which can reduce the probability of scratches on the coating layer of the coated sheet materials.

[0018] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the specific embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the disclosure of the present application to those skilled in the art.

[0019] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0020] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0021] See Figures 1-4 This application provides a packaging accessory for coated sheet materials. The packaging accessory is used in packaging boxes for coated sheet materials, where the coated sheet material can be silver-plated glass 50. The packaging box is a wooden crate. Generally, the sealed packaging box includes a bottom plate 11, a cover plate, a front plate, a back plate 12, and two side plates 13. The bottom plate 11, cover plate, front plate, back plate 12, and two side plates 13 together form a closed compartment 10. Multiple pieces of silver-plated glass 50 are stored in the compartment 10, and each adjacent pair of silver-plated glass 50 is separated by a liner. The plate corresponding to the rear side of the silver-plated glass 50 is the back plate 12, the plate corresponding to the front side is the front plate, and the plates corresponding to the left and right sides are the two side plates 13. It should be noted that during the packaging process of the silver-plated glass 50, the cover plate and front plate of the packaging box are not yet installed.

[0022] like Figure 1 and Figure 2 As shown, this application embodiment provides a packaging accessory for coated sheet materials. The packaging accessory includes a first rod 21, a second rod 22, two connecting members 30, and at least two locking members 40. The second rod 22 is spaced apart from the first rod 21, forming a gap 20 with the first rod 21 for accommodating multiple sheets of backing paper. The two connecting members 30 are respectively located at both ends of the first rod 21, and are connected to two opposite side plates 13 in the packaging box of the coated sheet materials, so that the first rod 21 is positioned above the box compartment 10 of the packaging box. The multiple locking members 40 are distributed along the length of the second rod 22 and are movably connected to the second rod 22, for holding all the backing paper in the gap 20 against the first rod 21, allowing the backing paper to hang down into the box compartment 10.

[0023] During the packing process of the silver-plated glass 50, firstly, one end of an appropriate number of backing papers is placed in the gap 20 between the first rod 21 and the second rod 22. The locking piece 40 on the second rod 22 is used to hold all the backing papers against the first rod 21, thus fixing the backing papers to the first rod 21. Then, the two connecting pieces 30 at both ends of the first rod 21 are used to connect to the two side plates 13 to place the first rod 21 across the top of the box 10. At this time, all the backing papers are kept above the box 10. After the i-th silver-plated glass 50 is placed, the backing paper is folded down so that it hangs naturally in the box 10 without needing to be manually patted and is in a flat state. Then, the (i+1)-th silver-plated glass 50 is placed, where i is a positive integer. This process is repeated until all the silver-plated glass 50s are installed before installing the front panel and cover of the packaging box. As can be seen, the packing accessories in this application embodiment can also be called paper-laying fixtures. By means of paper-laying fixtures, workers can replace the manual operation of patting the backing paper, reducing the probability of scratches on the coating layer of the coated sheet opposite to the backing paper, thereby improving the yield of the coated sheet after it is transported through the packaging box.

[0024] like Figure 3 As shown, in some embodiments, the second rod 22 is located above the first rod 21. The second rod 22 and the first rod 21 are distributed vertically, which makes it easier to fill the paper in the gap 20 and then lock the filled paper in place compared to the second rod 22 and the first rod 21 being distributed at intervals in the same horizontal plane.

[0025] like Figure 3 and Figure 4 As shown, the locking element 40 further includes a ring 41 and a bolt 42. The ring 41 is fixedly connected to the second rod 22, and the bolt 42 passes through the ring 41 and is threadedly connected to the ring 41 to move closer to or away from the first rod 21. The bolt 42 includes a T-bolt, which can be screwed in or out of the ring 41 without tools. The locking element 40 is distributed on the front or rear side of the second rod 22, and the lower part of the locking element 40 is opposite to the upper surface of the first rod 21, thereby enabling the locking element 40 to lock the lining paper onto the first rod 21. Specifically, when multiple layers of lining paper are placed together in the gap 20, the worker rotates the T-bolt to bring the lining closer to the first rod 21. The T-bolt moves forward until it can no longer move forward. At this point, the lining paper is clamped by the T-bolt onto the upper surface of the first rod 21, thus completing the locking of the assembled lining paper.

[0026] To improve the locking effect, the number of locking elements 40 can be four, and the four locking elements 40 are evenly spaced along the length direction of the second rod 22.

[0027] like Figures 1-4As shown, in some embodiments, the connector 30 includes a slot 31 and a second locking member 33. The slot 31 is connected to the end of the first rod 21 and is used to adapt to the top of the side plate 13. The second locking member 33 is movably mounted on the groove edge 32 of the slot 31 away from the other slot 31. Further, the second locking member 33 includes a second ring 34 and a second bolt 35. The second ring 34 is fixedly connected to the slot 31 and sleeved on the second bolt 35. The second bolt 35 is threadedly connected to the second ring 34 to move closer to or further away from the side plate 13 connected to the slot 31. The second bolt 35 can be a T-bolt, which facilitates the screwing of the second bolt 35 into or out of the second ring 34 without the aid of tools. The slot 31 is roughly U-shaped, with its opening facing downwards. The width of this opening is greater than the thickness of the side plate 13, allowing the slot 31 to be placed at the top of the side plate 13. Then, by rotating the second bolt 35 corresponding to the groove edge 32 away from the other slot 31, the second bolt 35 moves forward and engages the side plate 13 in the slot 31, thereby stably mounting the entire packing accessory above the box compartment 10 via the connector 30. And, as... Figure 4 As shown, a slot 31 is equipped with two second locking elements 33 to ensure the reliability of the connection between the connector 30 and the side plate 13.

[0028] Generally, silver-plated glass 50 of different sizes can be transported using packaging boxes of different sizes. The spacing between the two side panels 13 in these different packaging boxes is different. Based on this, in some embodiments, such as... Figure 3 and Figure 4 As shown, both the first rod 21 and the second rod 22 include a fixed rod 23 and a movable rod 24. The fixed rod 23 and the movable rod 24 have the same length direction. The movable rod 24 is mounted on the fixed rod 23 and can move along the length direction of the fixed rod 23 to change the distance between the two connecting members 30. In this embodiment, the first rod 21 and the second rod 22 appear in pairs. The structures of the two rods are roughly the same. When installing the packing accessories on the packaging box, one slot 31 can be first clipped onto the side plate 13. According to the specifications of the packaging box, the two movable rods 24 can be adjusted so that the other slot 31 can be fitted onto the other side plate 13. When both connecting members 30 are fixedly connected to the side plate 13, the movable rod 24 passes through the fixed rod 23, so that the first rod 21 and the second rod 22 are erected above the box chamber 10.

[0029] Furthermore, in the second rod 22, at least one locking element 40 is evenly distributed on both the fixed rod 23 and the movable rod 24. The multiple evenly distributed locking elements 40 can maintain a uniform distribution of pressure on the liner paper. To ensure that the second rod 22, composed of the fixed rod 23 and the movable rod 24, can meet the requirements of multiple packaging box sizes, both the fixed rod 23 and the movable rod 24 have a certain length. Therefore, designing locking elements 40 on both the fixed rod 23 and the movable rod 24 can ensure the stability of the liner paper within the gap 20.

[0030] like Figures 5-7 As shown, this application embodiment also provides a packaging box for coated sheet materials, including a bottom plate 11, a back plate 12, two side plates 13, and a packing accessory for coated sheet materials as described above; wherein, the bottom plate 11 is connected to the back plate 12 and the side plates 13, and each of the left and right ends of the back plate 12 is connected to a side plate 13 to form at least one box chamber 10, and the packing accessory is mounted on the two side plates 13 so that the liner paper held by the packing accessory can hang down in the box chamber 10.

[0031] In this case, the packaging box is not a complete box body during the packing process of the silver-plated glass 50. It includes a bottom plate 11, a back plate 12, and two side plates 13. The side plates 13, the back plate 12, and the other side plate 13 are connected end to end to form a V-shaped structure. The packing accessories with lining paper are then mounted above the box chamber 10 via connectors. The packaging box embodiment has been described in detail in the above-mentioned packing accessory embodiment, so it will not be repeated here.

[0032] like Figure 5 As shown, during the packing process of the silver-plated glass 50, firstly, one end of an appropriate number of backing papers is placed in the gap 20 between the first rod 21 and the second rod 22. The locking piece 40 on the second rod 22 is used to hold all the backing papers against the first rod 21, thus fixing the backing papers to the first rod 21. Then, the two connecting pieces 30 at both ends of the first rod 21 are used to connect to the two side plates 13 to place the first rod 21 across the top of the box 10. At this time, all the backing papers are kept above the box 10. After the i-th piece of silver-plated glass 50 is placed, the backing paper is folded down so that it hangs naturally in the box 10 without needing to be manually patted and is in a flat state. Then, the (i+1)-th piece of silver-plated glass 50 is placed, and this process is repeated until all the silver-plated glass 50s are installed before installing the front panel and cover of the packaging box.

[0033] As can be seen, the packing accessories in this application embodiment can also be called paper-laying fixtures. By means of paper-laying fixtures, workers can replace the manual operation of patting the backing paper, reducing the probability of scratches on the coating layer of the coated sheet opposite to the backing paper, thereby improving the yield of the coated sheet after it is transported through the packaging box.

[0034] If the silver-plated glass 50 is a skylight, the long side of the skylight faces downwards; if the silver-plated glass 50 is a windshield, the small side of the windshield faces upwards. Glasses in the same compartment 10 are separated by virgin pulp lining paper, and the smooth surface of the virgin pulp lining paper is in contact with the silver plating layer of the glass, with the silver plating layer facing forward. The lining paper is laid by packing accessories. In order to prevent oxidation of the silver-plated glass 50, the entire box of glass can also be sealed with aluminum foil. The use of aluminum foil sealing is known to those skilled in the art, so it will not be described in detail here.

[0035] However, common packaging boxes are all single wooden crates, meaning each crate has only one compartment. During transportation, these single wooden crates are relatively thin and lack stability. Shaking of the crate can cause scratches to the silver-plated film layer against the lining paper, thus resulting in scratches on the glass film. Preferably, such as... Figure 6 and Figure 7 As shown, each end of the back panel 12 is connected to a side panel 13 to form two compartments 10. The two compartments 10 are arranged back-to-back via the back panel 12, and the side panels 13 are extended side panels. In this embodiment, the single wooden box is expanded into a double wooden box, and the specifications of each compartment 10 in the double wooden box can be the same as those of the compartments 10 in the single wooden box. Therefore, the side panels 13 of the double wooden box are extended side panels.

[0036] For double-walled wooden crates, after both compartments 10 are filled with silver-plated glass 50 and sealed, the crates are secured with strapping, two horizontally and two vertically, to enhance stability. Single-walled wooden crates have poor stability after packing; during transport, the crates and glass products may shake, causing friction between the silver-plated glass 50 and the lining paper, resulting in scratches on the silver coating. This embodiment optimizes the crate structure, achieving a 0% scratch rate on the silver coating of sunroof double-silver products delivered to the customer, with a 100% yield; and a 17% scratch rate on the silver coating of windshield triple-silver products delivered to the customer, with an 83% yield. This improves the yield of sheet-like coated products and reduces scratches on the coating. Here, "double-silver sunroof" means one side of the sunroof glass has two layers of silver coating, and "triple-silver windshield" means one side of the windshield has three layers of silver coating.

[0037] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this application and do not limit the scope of protection of this patent application.
