Description

Technical Field

[0001] The utility model belongs to the technical field of packaging, and particularly relates to a corner sleeve buffering device. Background Art

[0002] With the change of modern lifestyle and the rapid development of the logistics industry, many items are traded through logistics, such as electronic products, chemical products, pharmaceutical products, ceramics, glass, and other daily necessities. During the storage or transportation of these items, situations such as extrusion, collision, and dropping are inevitable, resulting in product damage or deformation, bringing serious losses to people.

[0003] In order to protect products, before storage or transportation, people will use packaging boxes in cooperation with inflatable buffering devices, etc. to package products. When the packaged items are collided or impacted by external forces, the air columns in the inflatable buffering device can provide a buffering effect to avoid damage to the items.

[0004] However, the size specifications of existing packaged items such as liquid crystal TVs are becoming increasingly large, resulting in inconvenience in handling and installation. Therefore, during the transportation of packaged items such as liquid crystal TVs, it is easy to collide with the four peripheral corners of the packaged items such as liquid crystal TVs due to frequent handling, resulting in damage or wear to the four peripheral corners. As existing liquid crystal TVs become thinner and thinner, when the corners of the liquid crystal TVs are impacted during handling, the existing corner sleeve buffering structure can no longer buffer the impact force brought by the impact, resulting in product damage. Summary of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a corner sleeve buffering device, aiming to solve the technical problem of poor buffering force of the existing corner sleeve buffering structure.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A corner sleeve buffering device includes a first air column surface, a second air column surface arranged opposite to the first air column surface, and a bottom column surface for communicating the first air column surface with the second air column surface. A third air column surface is arranged between the first air column surface and the second air column surface. The third air column surface is connected to the second air column surface through a top column surface. One end of the third air column surface close to the bottom column surface extends outward to be heat-sealed to a suspension film on the first air column surface. The suspension film, the first air column surface, and the third air column surface enclose a containing space for containing goods.

Each of the first air columns and each of the first heat-sealing lines communicate with each other. The first heat-sealing lines of the second air column surface and the third air column surface are both heat-sealed and connected through the heat-sealing block.

[0009] Further, the first air column surface and the bottom column surface each include second air columns and second heat-sealing lines that communicate with each of the first air columns and each of the first heat-sealing lines. The second heat-sealing line at the end of the first air column surface is heat-sealed and connected to the first heat-sealing line at the end of the third air column surface.

[0010] Further, the second heat-sealing line at the end of the first air column surface, the first heat-sealing line at the end of the second air column surface, and the first heat-sealing line at the end of the third air column surface are heat-sealed and connected.

[0011] Further, a plurality of third heat-sealing lines are also provided on the third air column surface for dividing each of the first air columns into a pair of third air columns.

[0012] Further, a part of the first air column on the second air column surface is heat-sealed and connected to the third heat-sealing line.

[0015] Further, the length of the suspension film is greater than the distance between the first air column surface and the third air column surface.

[0016] The beneficial effects of the present utility model are as follows: Compared with the prior art, in an angle sleeve buffer device of the present utility model, by providing a first air column surface and a second air column surface, and arranging a third air column surface between the first air column surface and the second air column surface, and respectively connecting the above-mentioned air column surfaces to each other through a bottom column surface and a top column surface, when the end angle of the packaged article is placed in the accommodating space, good buffering for the packaged article is achieved through the formed multi-layer air column surfaces; one end of the third air column surface extends outwards with a suspension film, thereby cooperating with the bottom column surface to form a double-layer buffer structure, further enhancing the buffering resistance ability.

[0030] As Figures 1 to 3As shown in the figure, this embodiment provides a corner sleeve buffer device, including a first air column surface 1, a second air column surface 2, and a bottom column surface 3. The second air column surface 2 is arranged opposite to the first air column surface 1. The bottom column surface 3 can be used to connect the bottoms of the first air column surface 1 and the second air column surface 2. In addition, a third air column surface 4 is provided between the first air column surface 1 and the second air column surface 2. The third air column surface 4 is connected to the second air column surface 2 through a top column surface 5. One end of the third air column surface 4 close to the bottom column surface 3 extends outwards with a suspension film 6. One side of the suspension film 6 is heat-sealed on the first air column surface 1. The suspension film 6, the first air column surface 1, and the third air column surface 4 enclose a containing space for containing the goods. By setting the first air column surface 1 and the second air column surface 2, and arranging the third air column surface 4 between the first air column surface 1 and the second air column surface 2, and respectively connecting the above-mentioned air column surfaces through the bottom column surface 3 and the top column surface 5, when the end corners of the packaged article are placed in the containing space, good buffering for the packaged article is achieved through the formed multi-layer air column surfaces; since one end of the third air column surface 4 extends outwards with a suspension film 6, a double-layer buffer structure is formed in cooperation with the bottom column surface 3, further enhancing the buffer resistance ability.

[0031] Further, please refer to Figure 3 As shown in the figure, at least one heat-sealing block 7 is provided between the second air column surface 2 and the third air column surface 4. By setting the heat-sealing block 7, the second air column surface 2 and the third air column surface 4 can be heat-sealed and fixedly connected, so that the second air column surface 2 and the third air column surface 4 form an integral body, thereby enhancing the buffering performance of the corner sleeve and improving the impact resistance ability.

[0032] Preferably, in this application, the suspension film 6 is heat-sealed and connected to the first air column surface 1 through the heat-sealing block 7. Of course, in this embodiment, according to the actual situation and specific requirements, the suspension film 6 can also be heat-sealed and connected to the first air column surface 1 through a heat-sealing line, and this is not uniquely limited here.

[0033] Further, please refer to Figure 3 As shown in the figure, the second air column surface 2, the third air column surface 4, and the top column surface 5 all include a plurality of first air columns 21 and first heat-sealing lines 22 arranged alternately in sequence. The first air columns 21 and the first heat-sealing lines 22 on the second air column surface 2, the third air column surface 4, and the top column surface 5 are mutually connected. The first heat-sealing lines 22 of the second air column surface 2 and the third air column surface 4 are all heat-sealed and connected through the heat-sealing block 7. By heat-sealing the heat-sealing block 7 on the first heat-sealing lines 22 of the second air column surface 2 and the third air column surface 4, it is convenient for processing during the production process, that is, the heat-sealing block 7 can be heat-sealed on the first heat-sealing line 12 while preparing the first heat-sealing line 12, greatly simplifying the processing technology; on the other hand, through heat-sealing, the second air column surface 2 and the third air column surface 4 form an integral body, overall enhancing the buffering performance of the corner sleeve and greatly improving the impact resistance ability of the corner sleeve.

[0034] Preferably, the number of the heat-sealing blocks 7 is the same as that of the first heat-sealing lines 41. That is, one heat-sealing block 7 is correspondingly provided on each first heat-sealing line 41, so as to enhance the bonding force between the second air column surface 2 and the third air column surface 4 and improve the overall performance of the two air column surfaces. Of course, in this embodiment, the number of the heat-sealing blocks 7 can be determined according to the actual situation (such as referring to the weight of the packaged goods), and the number of the heat-sealing blocks 7 can be one, two, four, six, eight, etc., which is not uniquely limited here.

[0035] Preferably, the heat-sealing block 7 can be arranged at any one of the top, middle and bottom of the above-mentioned first heat-sealing line 22, which is not uniquely limited here.

[0036] Further, please refer to Figure 3 As shown, both the first air column surface 1 and the bottom column surface 3 include a plurality of second air columns 11 and second heat-sealing lines 12. Each second air column 11 communicates with each first air column 21, and each second heat-sealing line 12 communicates with each first heat-sealing line 22. In addition, the second heat-sealing line 12 at the end of the first air column surface 1 is heat-sealed and connected to the first heat-sealing line 12 at the end of the third air column surface 4. In this way, by heat-sealing and connecting the first heat-sealing line 22 and the second heat-sealing line 12 at the end positions of the first air column surface 1 and the third air column surface 4, the first air column surface 1 and the third air column surface 4 form an integral structure, enhancing the impact resistance of the air columns on both sides and further enhancing the buffering performance of the corner sleeve.

[0037] Further, please refer to Figure 3 As shown, the second heat-sealing line 12 at the end of the first air column surface 1 is heat-sealed and connected to the first heat-sealing line 22 at the end positions of the second air column surface 2 and the third air column surface 4. By heat-sealing and connecting the heat-sealing lines on the three air column surfaces, a three-sided strengthening structure at the tail is formed, greatly enhancing the bonding force between the first air column surface 1, the second air column surface 2 and the third air column surface 4, improving the integrity of each air column surface, and greatly enhancing the buffering performance of the corner sleeve.

[0038] In this application, according to the weight of the packaged goods, that is, when the weight of the packaged goods is small, heat-sealing blocks 7 can be provided only on the second air column surface 2 and the third air column surface 4. An integral body is formed by the second air column surface 2 and the third air column surface 4 to realize the buffer packaging of smaller goods; when the weight of the packaged goods is large, the first air column surface 1 and the third air column surface 4 are fixedly connected through the heat-sealing lines on each air column surface, and then the second air column surface 2 and the third air column surface 4 are fixedly connected through the heat-sealing blocks 7. Thus, the three air column surfaces are heat-sealed and fixed, further enhancing the impact resistance of the corner sleeve, so as to meet the buffering of different packaged goods weights and increase its scope of use.

[0039] In the present application, the ends of the first air cylinder 1, the second air cylinder 2, and the third air cylinder 4 are heat-sealed and fixed, and fixed at the end positions. On the one hand, interference with the accommodating space caused by heat sealing at other positions is avoided; on the other hand, since the corner sleeves are prone to breakage due to stress concentration and greater force during use, they are heat-sealed at the end positions so that they can better withstand the stress at the end corners, thereby specifically enhancing the buffering force at the end corners of the corner sleeves.

[0040] For further information, see Figure 2 and Figure 3 As shown, the third air column surface 4 is also provided with a plurality of third heat sealing lines 41, and each third heat sealing line 41 can be used to divide each first air column 21 into a pair of third air columns 42. The first air column 21 with a larger air column volume is divided into a pair of third air columns 42 with a smaller air column volume by the third heat sealing line 41, so as to avoid that when the first air column surface 1 and the third air column surface 4 are heat-sealed, the first air column 21 with a larger air column volume squeezes each other and affects the accommodation space of the corner sleeve.

[0041] Preferably, the first air column 21 on the second air column surface 2 is heat-sealed to a portion of the third heat-sealing line 41. In this way, the bonding force between the second air column surface 2 and the third air column surface 4 can be enhanced to improve the impact resistance.

[0042] For further information, see Figure 2 and Figure 3 As shown, the first air column 21 on the third air column surface 4 includes a plurality of first air column tubes 211 and a plurality of second air column tubes 212, the third heat sealing line 41 is arranged on the second air column tube 212, the diameter of the first air column tube 211 is greater than the diameter of the second air column tube 212, and the second air column surface 2 also includes a plurality of first air column tubes 211 and a plurality of second air column tubes 212. By making the diameter of the first air column tube 211 larger than the diameter of the second air column tube 212, when the diameter of the first air column tube 211 on the third air column surface 4 contacts the diameter of the first air column tube 211 on the first air column surface 1, the distance between the third air column surface 4 and the first air column surface 1 can be stretched, so that the end angle of the packaged goods can be placed in the accommodating space.

[0043] In the present application, a plurality of heat sealing points 43 are provided at the bending part between the second air column surface 2 and the top column surface 5. By providing the heat sealing points 43, it is convenient to bend each air column surface, thereby improving the processing efficiency.

[0044] In the present application, since the corner sleeve buffer device is formed by bending the air cylinder on one side to form the above-mentioned air cylinders, in order to facilitate processing and manufacturing, heat sealing points are provided at the bending points of each air cylinder, thereby facilitating bending to form the above-mentioned corner sleeve buffer device, greatly improving processing efficiency.

[0045] Furthermore, the length of the suspension film 6 is greater than the distance between the first air column surface 1 and the third air column surface 4. In this way, it is ensured that the suspension film 6 has a good extension space and can effectively buffer the goods.

[0046] In this application, it should be particularly emphasized that the above "first", "second", "third", and "fourth" are only for the convenience of describing each technical feature and do not limit the technical solution of the corner sleeve buffer device of this application.

[0047] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
