Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a paper packaging pad for air conditioners and an air conditioner packaging box. Background Technology

[0002] Air conditioner packaging boxes play a crucial role in the entire process of air conditioner transportation, storage, sales, and user experience. Air conditioners are precision appliances, containing core components such as compressors, evaporators, and condensers, and their outer casings are mostly made of metal or plastic, making them susceptible to damage from impacts, compression, and vibration. Therefore, air conditioner packaging boxes need to provide impact and compression resistance.

[0003] In existing technologies, air conditioner packaging pads are mostly made of EPS, EPP, and EPE materials, which are not easily degradable and can pollute the environment. Furthermore, EPS, EPP, and EPE are prone to generating static electricity through friction, which can damage electronic components. All-paper packaging, on the other hand, is recyclable, reducing resource waste, is biodegradable, and minimizes environmental pollution. It is also naturally anti-static and less likely to damage electronic components. Traditional all-paper packaging often uses a composite of corrugated paper and honeycomb paper. Honeycomb paperboard is easily deformed; when significantly deformed, it is compressed, losing its cushioning function and failing to protect large and fragile products like air conditioners.

[0019] With the above structure, there are usually two end pads, which are placed at both ends of the air conditioner.

[0020] According to the present invention, a paper packaging pad for an air conditioner is provided, wherein the wrapping layer encloses the honeycomb cardboard buffer layer and the corrugated cardboard support layer as a whole.

[0021] The above structural design achieves both integrity and protection for the packaging pad.

[0022] According to the present invention, a paper packaging pad for air conditioners is provided, wherein the thickness of the end head is 28-32mm.

[0023] The above structural design allows for better matching with air conditioners and enables efficient use of materials.

[0024] According to the all-paper packaging pad for air conditioners provided by this utility model, the thickness of the honeycomb cardboard buffer layer is less than or equal to the thickness of the corrugated cardboard support layer.

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] In the description of the embodiments of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] The following is combined Figures 1-9This invention describes a paper packaging pad for air conditioners, comprising a padding part 10 and a limiting part 20.

[0045] like Figure 1 and 2 As shown, the support portion 10 is parallel to the horizontal plane and located on one side of the air conditioner. It serves as a basic support surface, bearing part of the air conditioner's weight and preventing the air conditioner body from directly contacting the bottom of the packaging box, thus reducing friction or compression. The limiting portions 20 are arranged in pairs, vertically positioned on both sides of the support portion 10 and located around the perimeter of the air conditioner. The space enclosed by the support portion 10 and the limiting portions 20 is used to hold the air conditioner in place, restricting its left-right or front-back movement within the packaging box and preventing damage due to displacement or collision during transportation.

[0046] Both the padding part 10 and the limiting part 20 facing the air conditioner are provided with a honeycomb paperboard buffer layer 1, that is, they are set in the inner layer of the packaging pad. The honeycomb paperboard buffer layer 1 has good buffering properties. That is, the honeycomb paperboard buffer layer 1 is attached to the air conditioner and can play the buffering role of the honeycomb paperboard. The honeycomb paperboard absorbs the kinetic energy during the drop process through small deformation, thereby directly protecting the air conditioner and absorbing the impact energy.

[0047] Both the padding part 10 and the limiting part 20 on the side facing away from the air conditioner are provided with a corrugated cardboard support layer 2. The corrugated cardboard support layer 2 is located on the outside of the interlayer, that is, on the outer layer of the packaging pad, to ensure the stability of the pad's own structure and provide support force. It can give full play to the good support of the corrugated cardboard support layer 2, ensure the stability of the air conditioner product stacking process, and prevent the pad from undergoing large deformation during the drop process.

[0048] The corrugated cardboard support layer 2 is preferably made of vertical corrugated composite cardboard.

[0049] Both the padding part 10 and the limiting part 20 are provided with a wrapping layer 3 on their outer periphery. The wrapping layer 3 wraps the honeycomb paperboard buffer layer 1 and the corrugated paperboard support layer 2 into one unit, that is, it completely wraps the outer periphery, which can take into account both the integrity and protection of the pad block structure. It can be understood that the wrapping layer 3 tightly fixes the corrugated paperboard support layer 2 and the honeycomb paperboard buffer layer 1 into one unit, preventing delamination and falling off; at the same time, it isolates external dust and a small amount of moisture, protecting the performance of the internal materials.

[0050] Therefore, the packaging pad for air conditioners provided by this utility model not only uses all-paper packaging, which is environmentally friendly and easy to recycle, but also directly contacts the air conditioner through the honeycomb cardboard buffer layer 1, thus mitigating the impact damage to precision components; at the same time, the corrugated cardboard support layer 2 ensures that the pad does not deform, ensuring that the air conditioner will not be crushed during stacking, or that the air conditioner will shift due to the collapse of the pad; the enclosed structure restricts the shaking of the air conditioner body, thus avoiding collisions with the inner wall of the packaging box during transportation.

[0051] In one feasible embodiment of this utility model, the wrapping layer 3 comprises a single-layer corrugated cardboard. This single-layer corrugated cardboard possesses a certain degree of stiffness and integrity, enabling it to tightly wrap the honeycomb cardboard cushioning layer 1 and the corrugated cardboard support layer 2. By cutting, folding, and then bonding it to the outer periphery of the two core materials, delamination and detachment of the honeycomb cardboard cushioning layer 1 and the corrugated cardboard support layer 2 during transportation or use are prevented, ensuring the overall structural stability of the pad. Single-layer corrugated cardboard is one of the lightest and lowest-cost types of corrugated cardboard. As a wrapping layer, it only needs to fulfill the basic function of fixing the shape and does not need to undertake core cushioning or support functions. Therefore, it can reduce the overall weight and material cost of the pad while ensuring functionality.

[0052] In one feasible embodiment of this utility model, the honeycomb paperboard buffer layer 1, the corrugated paperboard support layer 2, and the wrapping layer 3 are bonded and fixed together, which can not only meet the material properties, but also enhance the structural stability and avoid interlayer separation.

[0053] like Figure 1 and Figure 2 As shown, in a feasible embodiment of this utility model, the all-paper packaging pad is a central pad, the padding part 10 is located on the bottom or top side of the air conditioner, and there are two limiting parts 20. If the padding part 10 is located on the bottom side of the air conditioner, it acts as a bottom support pad, directly bearing the main weight of the air conditioner, preventing the bottom of the air conditioner body from directly contacting the bottom plate of the packaging box, and at the same time, the limiting part 20 fixes the bottom position to prevent the bottom from shifting during transportation. If the padding part 10 is located on the top side of the air conditioner, it can cooperate with the bottom pad to form corresponding upper and lower supports. In stacking scenarios, the top pad can distribute the pressure from above, preventing the top shell of the air conditioner from being deformed by pressure; at the same time, during handling, the top limiting part can prevent the air conditioner body from moving upward.

[0054] When using an air conditioner, one or more spacers can be used in the middle of the packaging box, depending on the actual situation.

[0055] like Figures 3-9 As shown, in a feasible embodiment of this utility model, the all-paper packaging pad is an end pad, and there are two pad holding parts 10, which are arranged opposite to each other, located on the top and bottom sides of the air conditioner, respectively, and both pad holding parts 10 are connected to the limiting parts 20. The arrangement of the two pad holding parts 10, together with the limiting parts 20 on both sides, realizes the vertical and horizontal clamping structure of the end of the air conditioner. The top pad holding part 10 is in contact with the top surface of the end of the air conditioner, bearing the pressure above the end and avoiding direct pressure on the top surface. The bottom pad holding part 10 is in contact with the bottom surface of the end, supporting the weight of the end, and forms a vertical correspondence with the top pad holding part 10, limiting the vertical movement of the end face.

[0056] like Figures 4-7As shown, further, the end pad also includes an end head 30 based on the above embodiment. The two sides of the end head 30 are correspondingly connected to the limiting portion 20, and the top and bottom sides of the end head 30 are correspondingly connected to the pad holding portion 10. The end head 30 includes a honeycomb paperboard buffer layer 1, and a wrapping layer 3 is provided on the outer periphery of the end head 30. The end head 30 can absorb kinetic energy through its own small deformation, preventing the impact force from being directly transmitted to the end of the air conditioner. At the same time, the wrapping layer on the outer periphery of the end head 30 can fix the shape of the honeycomb paperboard buffer layer, preventing the buffer layer from excessively deforming or falling off during impact.

[0057] It should be noted that the end pads are interchangeable on both sides of the air conditioner, making them easy to use.

[0058] In one feasible embodiment of this utility model, the wrapping layer 3 wraps the honeycomb paperboard buffer layer 1 and the corrugated paperboard support layer 2 as a whole, ensuring the integrity of the pad, ensuring that the functions of buffering and support are not lost, and strengthening the structural stability and protective integrity, while taking into account the characteristics of paper materials and the environmental protection and low cost requirements of packaging.

[0059] It should be noted that the wrapping layer 3 can be connected into one piece by folding and wrapping the various cardboard layers.

[0060] In one feasible embodiment of this utility model, the thickness of the end head is 28-32mm, more preferably 30mm.

[0061] In one feasible embodiment of the present invention, the thickness of the honeycomb paperboard buffer layer 1 in the padding part 10 and the limiting part 20 is less than or equal to the thickness of the corrugated paperboard support layer 2.

[0062] Preferably, the thickness of the corrugated cardboard support layer 2 is 14-16 mm. More specifically, the thickness of the honeycomb cardboard buffer layer 1 in the padding portion 10 is 10 mm, and the thickness of the corrugated cardboard support layer 2 is 15 mm. The thickness of both the honeycomb cardboard buffer layer 1 and the corrugated cardboard support layer 2 in the limiting portion 20 is 15 mm.

[0063] In summary, the all-paper packaging pad for air conditioners provided by this utility model has a simple structure, is versatile, and is easy to use. The combination of the honeycomb cardboard buffer layer 1 and the corrugated cardboard support layer 2 gives the pad both support and cushioning, providing excellent protection. The outer side is further wrapped with a single-layer corrugated cardboard wrapping layer 3, ensuring a smooth surface and maintaining both aesthetics and structural integrity. During stacking and clamping transportation, the corrugated cardboard support layer 2 fully utilizes its support to prevent product deformation. During drops, the corrugated cardboard provides support, reducing large deformations of the packaging structure, while the honeycomb cardboard absorbs kinetic energy during the drop, thus protecting the product from damage.

[0064] The second aspect of this utility model provides an air conditioner packaging box, including a box body and a paper packaging pad for air conditioners as described in the above embodiments. The box body has a receiving space for accommodating the air conditioner and the paper packaging pad, and the paper packaging pad is used to support and limit the position of the air conditioner.

[0065] Since the air conditioner packaging box in this embodiment adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
