Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a honeycomb packaging liner, a cushioning packaging system and a forming mechanism. Background Technology

[0002] With increasing global emphasis on environmental protection, green packaging has become an inevitable trend in the industry. Honeycomb paperboard, as a new type of environmentally friendly packaging material, demonstrates enormous potential and advantages in the packaging field due to its unique structure and excellent performance.

[0003] Because honeycomb paperboard has low rigidity and toughness, its cushioning performance is limited. Compared to mature foam packaging, it is weaker in resistance to drop impacts and compression. Therefore, most honeycomb packaging products currently require the combination of honeycomb paperboard with corrugated cardboard, paper corner protectors, composite paperboard, and foamed plastics to enhance their support or cushioning performance. This significantly increases material, process, and labor costs, limiting its scale of use. Furthermore, due to its relatively fixed and simple structure, honeycomb paperboard cannot be directly designed to mimic the appearance of irregularly shaped products, resulting in weak support and cushioning for the packaged items. Additionally, its appearance is not easily distinguishable, posing a risk of incorrect packing in packaging scenarios with specific assembly requirements. Moreover, honeycomb packaging liners also suffer from low secondary molding efficiency, low edge crush strength, and high manufacturing costs, making it difficult to replace foamed plastic materials at present.

[0051] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0052] Example 1:

[0053] like Figure 2 As shown, in this embodiment, the present invention provides a honeycomb packaging liner 3, including a paper-formed honeycomb cardboard outer frame 31, that is, the honeycomb cardboard outer frame 31 is made from a piece of cardboard; specifically, the honeycomb cardboard outer frame 31 is made from a single layer of honeycomb cardboard through multiple folds.

[0054] In this embodiment, the honeycomb paperboard outer frame 31 has a hexahedral structure, which can be either a cuboid or a cube. This hexahedral honeycomb paperboard outer frame 31 is formed by folding a single board multiple times.

[0055] The honeycomb packaging liner 3 provided by this utility model includes a paper-formed honeycomb paperboard outer frame 31. The honeycomb paperboard outer frame 31 is formed by folding a single layer of honeycomb paperboard, which can distribute the load to the entire liner, thereby improving the support of the single layer of honeycomb paperboard when subjected to side force. This ensures that the honeycomb packaging liner 3 still meets the requirements for protecting air conditioner products under complex logistics environment conditions such as stacking, dropping, and impact, and solves the problems of poor load-bearing capacity of honeycomb paperboard under side force and insufficient edge crush strength of single layer honeycomb paperboard.

[0056] Example 2:

[0057] In this embodiment, the structure of the single-layer honeycomb paperboard of the molded honeycomb paperboard outer frame 31 is specifically defined.

[0058] like Figure 3 As shown, specifically, as an optional embodiment of this utility model, the honeycomb paperboard outer frame 31 unfolds into an axially symmetrical structure. The single-layer honeycomb paperboard includes an inner cavity surface 311, an inner fold cover 312, and an outer fold cover 314. It should be noted that the inner cavity surface 311, the inner fold cover 312, and the outer fold cover 314 correspond to different areas on the same single-layer honeycomb paperboard, defined by their different positions after folding to form the honeycomb packaging liner 3. For example, the inner cavity surface 311 is used to form the inner cavity bottom surface of the honeycomb packaging liner 3; the inner fold cover 312 is used to form the four sides of the honeycomb packaging liner 3; the inner fold cover 312 is used to snap adjacent inner fold covers 312 together to form a stable honeycomb packaging liner 3.

[0059] In this embodiment, the inner cavity surface 311 is located at the center of the single-layer honeycomb paperboard;

[0060] There are four inner folding covers 312, which are connected to the four sides of the inner cavity surface 311 in a bendable manner; the length of the inner folding cover 312 is equal to the length of the corresponding side of the inner cavity surface 311, and the height of the four inner folding covers 312 is the same.

[0061] There are four outer folding covers 314, which are connected to the two opposite inner folding covers 312 in a bendable manner.

[0062] In other words, two of the four inner folding covers 312 are connected to the outer folding covers 314, while each outer folding cover 314 has only one side connected to the inner folding cover 312, and the other sides are free sides; in order to facilitate snap-fit, each outer folding cover 314 has a notch at one corner away from the inner cavity surface 311.

[0063] During bending and forming, the outer fold cover 314 overlaps the left and right sides of the honeycomb paperboard outer frame 31 to form a double-layer paperboard, avoiding localized concentrated stress; after forming, the honeycomb paperboard outer frame 31 is designed with a cut-out part 315, which can cooperate with the paper-plastic liner 2 to prevent mistakes.

[0064] Example 3:

[0065] like Figure 4 As shown, in this embodiment, as an optional implementation of the present invention, the honeycomb packaging liner 3 further includes an inner honeycomb plate 32; the honeycomb packaging liner 3 is a hexahedral structure with an open top; there are five inner honeycomb plates 32, which are respectively disposed on the five inner wall surfaces of the honeycomb packaging liner 3, and the five wall surfaces here include the front, back, left, right, four sides and the bottom surface.

[0066] As an optional embodiment of this utility model, the honeycomb packaging liner 3 further includes a support pad 33 disposed on the inner cavity honeycomb plate 32. Specifically, in this embodiment, the number of support pads 33 is one, located at the bottom of one side wall, for example, it can be disposed at the bottom of the front wall.

[0067] The honeycomb packaging liner 3 provided by this utility model also has a support pad 33 designed in the inner cavity of the liner, which can support and avoid the weak parts of the air conditioner product and reduce the impact of external forces; the support pad 33 can also separate the air guide plate of the air conditioner 100 from the inner cavity honeycomb plate 32 (front) to avoid the air guide plate being directly damaged by force.

[0068] Example 4:

[0069] like Figure 4 As shown, in this embodiment, as an optional implementation of the present invention, the honeycomb packaging liner 3 further includes a foolproof pad 34 disposed on the inner honeycomb plate 32. The foolproof pad 34 interferes with the structure of the air conditioner 100 when the liner is reversed, preventing the packaging action from being completed, thus achieving foolproof protection.

[0070] Specifically, in this embodiment, there is one anti-misalignment pad 34, which is disposed at the bottom of the side wall adjacent to the support pad 33, for example, at the bottom of the left wall. The anti-misalignment pad 34 is located at the edge of the left wall, close to the support pad 33.

[0071] The honeycomb packaging liner 3 provided by this utility model has a completely new design for its structure, which meets the needs of air conditioner products for error prevention and protection of the product structure during production, packaging, transportation and storage. After the honeycomb packaging liner 3 is formed, the setting of the error prevention pad 34 makes the liner have obvious and easily distinguishable structural features, which can effectively prevent the liner from being installed backwards during production and packaging. This solves the problem that honeycomb cardboard is difficult to conform to the appearance of irregular products, and the packaging liner made from it has the risk of being installed backwards and subjected to unreasonable force.

[0072] When using the honeycomb packaging liner 3, the positions of the support pad 33 and the anti-misalignment pad 34 need to be considered to ensure correct installation.

[0073] like Figures 6-9 This diagram illustrates the structure for four different application directions, of which only... Figure 6 The direction in the middle is the correct installation direction. At this time, the support pad 33 provides support for the panel of the air conditioner 100, preventing the air guide plate of the air conditioner 100 from directly contacting the honeycomb packaging pad 3; while Figures 7-9The directions shown are incorrect fitting directions. All three incorrect directions will prevent proper fitting due to interference between the anti-misfit pad 34 and the air conditioner 100. When placing the paper-plastic liner 2, the anti-misfit hook 21 and the cut-off part 315 need to cooperate for correct packaging, allowing it to provide support and cushioning.

[0074] During the assembly of the honeycomb packaging liner 3, the honeycomb cardboard outer frame 31 is first laid flat on the worktable. Then, five inner cavity honeycomb panels 32 are respectively glued to the inner cavity surface 311 and four inner folded covers 312, forming a buffer layer in five directions: front, back, left, right, and bottom of the honeycomb packaging liner 3. Afterward, the support pad 33 and the anti-fouling pad 34 are respectively glued to the front of the front inner cavity honeycomb panel 32 and the left inner cavity honeycomb panel 32, thus completing the assembly and bonding process of the honeycomb packaging liner 3, resulting in the honeycomb packaging liner 3.

[0075] Example 5:

[0076] In this embodiment, as Figure 1 and Figure 5 As shown, this utility model provides a cushioning packaging system, including a packaging carton and a honeycomb packaging liner 3; the honeycomb packaging liner 3 is fitted inside the packaging carton. This utility model's cushioning packaging system can be used as an air conditioner cushioning packaging system, featuring error-proof assembly, good cushioning performance, good support performance, and ease of manufacturing.

[0077] Furthermore, such as Figure 5 As shown, it also includes a high-strength paper-plastic liner 2 with several accessory cavities 22, which can be used to place common air conditioner accessories and limit their movement; specifically, the paper-plastic liner 2 has multiple protrusions and pits to form accessory cavities 22 of different shapes and sizes, which can be used to place air conditioner accessories and limit their movement to prevent them from moving out.

[0078] It should be noted that the accessory cavity 22 of the paper-plastic liner 2 is located on its top, and the specifications of each accessory cavity 22 can be the same or different to accommodate accessories of different specifications.

[0079] The accessory cavity is formed by a concave-convex structure.

[0080] In this embodiment, the paper-plastic liner 2 is installed at the top opening of the honeycomb packaging liner 3. When the packaging box 1 is subjected to vertical pressure, the paper-plastic liner 2 can share part of the load and prevent the packaging box 1 and the honeycomb packaging liner 3 from being crushed.

[0081] The top surface of the paper-plastic liner 2 is flush with the honeycomb packaging liner 3. When the packaging box 1 is subjected to vertical pressure, it can share part of the load and prevent the packaging box 1 and the honeycomb packaging liner 3 from being crushed. The paper-plastic liner 2 is designed with anti-foolproof hanging ears 21 of different sizes on both sides, which cooperate with the cut-out part 315 of the honeycomb cardboard outer frame to prevent fooling.

[0082] The cushioning packaging system provided by this utility model, through the design of a high-strength paper-plastic liner 2, can meet the needs of accessory placement and avoid direct pressure on them; it provides support for the central space of the packaging, effectively cushioning the impact of stepping and stacking; and in conjunction with the honeycomb packaging liner 3, it further prevents the honeycomb packaging liner 3 from being reversed.

[0083] To facilitate installation and prevent mistakes, the honeycomb packaging pad 3 has cut-off portions 315 at the top edges on both sides; the paper-plastic pad 2 has anti-mistake hooks 21 at the corresponding positions.

[0084] The paper-plastic liner 2 has anti-foolproof hanging ears 21 of different sizes on both sides, which cooperate with the cut-out portion 315 of the honeycomb cardboard outer frame 31 to prevent fooling.

[0085] In this embodiment, the paper-plastic liner 2 has a U-shaped structure, including a top liner and side liners that are perpendicularly connected to both ends of the top liner; the height of the side liners in the vertical direction is not greater than the height of the inner cavity of the honeycomb packaging liner 3.

[0086] The cushioning packaging system provided by this utility model has been experimentally verified to meet the requirements of a 1.2m ultra-high drop packaging test. Under dynamic stacking with a safety factor of 4.5, the compression amount is only 6.25mm, which is far less than the 20mm specified by the enterprise standard. The random vibration and stacking vibration tests are qualified, which proves that the cushioning packaging system has excellent impact resistance, compression resistance and vibration resistance.

[0087] The packaging process flow diagram of the cushioning packaging system of this utility model is as follows: Figure 14 As shown.

[0088] Example 6:

[0089] In this embodiment, the present invention provides a molding mechanism 4 for processing the honeycomb packaging liner 3, which can realize one-time molding of honeycomb liner products, improve production efficiency, and reduce labor costs.

[0090] Specifically, such as Figures 10-13 As shown, the molding mechanism 4 includes a molding base 42, a push rod 41, and a molding device 43; wherein:

[0091] The bottom of the molding base 42 is equipped with a support rod, which can drive the molding base 42 to rise and fall vertically. It should be noted that the molding base 42 can be raised and lowered manually or mechanically. Manually, a person needs to hold the support rod and drive it to rise and fall, thereby raising and lowering the molding base 42. However, the manual method has the problems of low efficiency and high strength. The optimal method is to use mechanical power to drive it. For example, a lifting cylinder can be connected to the support rod, and the molding base 42 can be raised and lowered by controlling the rise and fall of the support rod.

[0092] The forming base 42 is used to support the inner cavity surface 311 of the single-layer honeycomb paperboard. Therefore, the specifications of the forming base 42 should be compatible with the specifications of the inner cavity surface 311. The two can be kept the same, and the forming base 42 is slightly larger than the specifications of the inner cavity surface 311.

[0093] The push rod 41 is located on the top of the molding base 42 and can move up and down reciprocally towards or away from the molding base 42; through the above structural arrangement, the push rod 41 and the molding base 42 can move back and forth in the vertical direction.

[0094] When the single-layer honeycomb paperboard is placed on the forming base 42, the single-layer honeycomb paperboard is pushed up by the push rod 41. At this time, the push rod 41 and the forming base 42 push up the two sides of the single-layer honeycomb paperboard respectively. Then the push rod 41 and the forming base 42 descend at the same time to complete the folding and forming of the honeycomb packaging liner 3.

[0095] The forming device 43 is fitted on the outside of the forming base 42 to fold and form the outer cover 314 and the inner cover 312 when the push rod 41 and the forming base 42 descend.

[0096] Furthermore, in order to increase the pushing area of ​​the push rod 41 and prevent damage to the honeycomb packaging liner 3, in this embodiment, the end of the push rod 41 has a push plate.

[0097] The push plate is smaller than the forming base size 42. The push plate can be round, square, triangular, or other irregular polygonal shapes.

[0098] As an optional embodiment of this utility model, the forming device 43 includes a forming limiting platform 431, an inner folding cover forming plate 432, and an outer folding cover forming rod 433; wherein:

[0099] The molding limiting platform 431 has an opening for the support rod to pass through, which is used to limit the molding base 42. It should be noted that the opening size should be smaller than the molding base 42 size to prevent the molding base 42 from passing through the opening.

[0100] The number of inner folding cover forming plate 432 and outer folding cover forming rod 433 is four each.

[0101] The inner folding cover forming plate 432 is arranged vertically on the four sides of the forming limiting stage 431; furthermore, the inner folding cover forming plate 432 is located in the middle of each side of the forming limiting stage 431.

[0102] The height H1 of the inner folding cover forming plate 432 is higher than the height H2 of the outer folding cover forming rod 433.

[0103] The outer folding cover forming rod 433 is arranged vertically at the four corners of the forming limiting platform 431.

[0104] In this embodiment, the outer folding cover forming rod 433 is made of a round rod, with an overall U-shape, V-shape, or triangular arrangement. The included angle between the two ends is an acute angle, meaning that when one side is vertical, the other side is tapered inward at a certain angle so that its end is flush with the formed outer folding cover 314. The outer folding cover 314 can be folded inward at 90°, allowing the gasket to be folded and formed in one step. The driving source can be a cylinder, motor, etc. Furthermore, the outer cover forming rods on both sides of the same side face each other.

[0105] As a further improvement of this utility model, the molding mechanism 4 also includes pressure sensors disposed on the molding base 42 and the molding limiting platform.

[0106] The first pressure sensor 421, located on the molding base 42, is arranged at the center of the molding base 42 and is located below the push rod 41.

[0107] The second pressure sensor located on the forming limiting platform is arranged on the inner side of the four inner folding cover forming plates 432, or on the inner side of the two opposite inner folding cover forming plates 432.

[0108] The molding mechanism 4 provided by this utility model is a newly designed molding mechanism 4 for honeycomb packaging liners 3, which improves the production efficiency of packaging liner products.

[0109] During the forming of the honeycomb packaging liner 3, the assembled honeycomb packaging liner is fed into the honeycomb liner forming mechanism 4. The honeycomb packaging liner triggers the first pressure sensor 421 on the forming base 42, causing the push rod 41 and the forming base 42 to move the honeycomb packaging liner downwards until the forming base 42 contacts the forming limiting stage 431, triggering the second pressure sensor 4311 on the forming limiting stage 431 to start timing, which is the forming stroke. During the forming stroke, ① the honeycomb packaging liner first contacts the inner folding cover forming plate 432, and drives the inner folding cover 312 to fold 90° towards the inner cavity surface 311. At this time, the outer folding cover 314 is also flipped up and is located at the 90° inward folding position; ② the honeycomb packaging liner continues to move downwards, and the outer folding cover 314 begins to contact the outer folding cover forming rod 433, and under the guidance of its triangular structure, it folds 90° again towards the inner cavity surface 311, finally completing the forming. After the molding process is maintained for a period of time, the push rod 41 and the molding base 42 move vertically upward, and the second pressure sensor 4311, the push rod 41 and the molding base 42 reset, which is the reset stroke.

[0110] Specifically, with the inner cavity surface 311 as the reference bottom surface, the inner folding cover forming plate 432 first pushes the inner folding cover 312 upward and folds it by 90°, forming a "square" structure. Since the outer folding cover 314 is connected to two of the inner folding covers 312 as a single piece, the outer folding cover 314 also folds by 90°. However, at this time, the outer folding cover 314 is in an outwardly expanding state and does not fit with the inner folding cover 312. Then, the outer folding cover forming rod 433 starts to contact the outer folding cover 314, and the inwardly converging triangular structure of the outer folding cover forming rod 433 drives the outer folding cover 314 to fold inward again by 90°, making it fit with the inner folding cover 312 and finally forming.

[0111] The forming process route of the honeycomb packaging cushion of the present utility model is as Figure 15 , and the specific operations are as follows: 1. Technicians evaluate the design drawings, sort out the bill of materials required for the product, and design the assembly process instruction document; 2. Cut the honeycomb paperboard of the required specifications according to the bill of materials; 3. Assemble and bond the honeycomb board according to the assembly process instruction document; 4. Send the assembled and bonded honeycomb paperboard into the oven for drying to accelerate the curing of the adhesive; 5. Send the dried honeycomb paperboard into the forming mechanism to be folded into a honeycomb packaging cushion; 6. Inspect and store the formed honeycomb packaging cushion.

[0112] It should be noted here that the edge crush strength of the honeycomb paperboard refers to: the maximum force value that can be borne per unit length when the honeycomb paperboard specimen is subjected to a continuously increasing pressure along the direction of the honeycomb core until the specimen is crushed.

[0113] First of all, it should be noted here that "inward" is the direction towards the center of the accommodation space, and "outward" is the direction away from the center of the accommodation space.

[0114] In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the Figure 1 orientation or positional relationship shown, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0115] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
