Description

Technical Field

[0001] The present application relates to the field of container processing, and in particular to a method for bonding support plates of a container and a container. Background Art

[0002] Containers, as a multimodal freight transport tool, are widely used around the world. In addition to the globally accepted standard containers, there are also numerous specialized containers with specialized functions. Some specialized containers require internal support panels to support crossbars. These support panels can then be used to block cargo or to place cargo on top of them for layered transport.

[0003] The existing support plate is welded to the side wall. This welding connection will damage the coating of the side wall. In this case, the damaged coating needs to be repaired (re-sprayed), which is labor-intensive, inefficient, and costly.

[0009] Step S3: maintaining pressure and curing the adhesively connected support plate and plate.

[0016] According to the container of the present application, the container includes a panel and a support plate. The panel and the support plate are bonded and connected by the aforementioned bonding method. The support plate is bonded to the panel, which avoids the support plate being welded to the panel and damaging the coating of the container.

[0054] To thoroughly understand the embodiments of the present application, a detailed structure will be provided in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail below, but in addition to these detailed descriptions, the present application may also include other embodiments.

[0055] First embodiment

[0056] This application provides a method for bonding the support plate 120 of a container. Figures 1 to 5 The container includes a box body 100 and a door 101. The box body 100 includes a wall body. The wall body includes a base frame, end walls, side walls and a top wall. The base frame, end walls, side walls and top wall form a roughly rectangular parallelepiped structure. One end of the box body 100 has a box opening. The door 101 is rotatably connected to one end of the box body 100 to open or close the box opening. Among them, at least one of the end wall, side wall, top wall and the door 101 includes a plate 110.

[0057] like Figures 2 to 5 As shown, the container further includes a support plate 120. The support plate 120 is attached to the panel 110. The support plate 120 is bonded to the panel 110. The support plate 120, disposed on the container body 100, is located inside the container body 100. When the container door 101 is closed, the support plate 120, disposed on the container door 101, is located inside the container door 101 near the center of the container body 100. The support plate 120 is used to provide a crossbeam. The crossbeam is used to prevent the movement of cargo within the container body 100. The crossbeam can also be used to support cargo.

[0058] Please refer to Figure 9 The bonding method includes step S1, step S2 and step S3.

[0059] Step S1 : spraying the plate 110 to form a first protective layer 114 .

[0060] In step S1, Figure 5 As shown, a coating can be sprayed on the outer surface of the plate 110 to form a first protective layer 114 (a coating of the plate 110) on the plate 110. The first protective layer 114 is composed of the coating. In this way, the first protective layer 114 can protect the plate 110 and improve the corrosion resistance of the plate 110.

[0061] The first protective layer 114 forms a coating on the inner surface of the container. Thus, the support plate 120 is located on the inner side of the container body 100 near the center of the container body 100 and / or on the inner side of the door 101 that closes the container opening near the center of the container body 100, and the container structure is simple.

[0062] The method of spraying paint on the plate 110 is a prior art and will not be described in detail here. The paint is a paint commonly used for spraying containers and will not be described in detail here.

[0063] Step S2 is performed after step S1.

[0064] Step S2 , applying glue to at least one of the outer surface of the first protective layer 114 (the outer surface of the first protective layer 114 away from the body of the plate 110 ) and the outer surface of the support plate 120 to form an adhesive layer 130 , and bonding them to the other through the adhesive layer 130 .

[0065] In step S2, if Figure 5 As shown, glue is applied on the outer surface of the first protective layer 114 to form an adhesive layer 130 , and the first protective layer 114 is bonded to the outer surface of the support plate 120 through the adhesive layer 130 .

[0066] It is understood that in an embodiment not shown, glue may be applied to the outer surface of the support plate to form an adhesive layer, and the support plate is bonded to the outer surface of the first protective layer through the adhesive layer.

[0067] The sizing method is a prior art and will not be described in detail here. The colloid is an existing adhesive that meets FDA requirements and will not be described in detail here.

[0068] Step S3 is executed after step S2.

[0069] Step S3: maintaining pressure and curing the support plate 120 and the plate member 110 that are bonded together.

[0070] In step S3, a force perpendicular to the plane where the support plate 120 and the plate 110 are located can be applied to the support plate 120 and the plate 110 by a pressure tool such as a clamp (for example, Figure 5 In the state shown, this force extends in the vertical direction), thereby clamping the support plate 120 to the plate 110 to which it is bonded. This ensures close contact between the support plate 120 and the plate 110, thereby maintaining pressure. After the preset pressure holding time, the adhesive layer 130 between the support plate 120 and the plate 110 is dried with hot air, thereby solidifying the adhesive layer 130. The preset pressure holding time can be set as needed. In this way, the relative position and state between the support plate 120 and the plate 110 can be maintained.

[0071] In this embodiment, the support plate 120 is bonded to the plate 110 to avoid damage to the coating of the container due to welding of the support plate 120 to the plate 110. There is no need for repair treatment such as repainting, which reduces the workload, increases efficiency, and reduces costs. In addition, deformation of the support plate 120 and the plate 110 caused by welding can also be avoided.

[0072] Furthermore, spraying the panel 110 before bonding it to the support plate 120 allows for a more uniform formation of the first protective layer 114 on the panel 110. This also avoids the need for repainting or other repairs at the joint between the panel 110 and the support plate 120 due to insufficient spraying after bonding. This results in a more consistent container.

[0073] Optionally, before step S2, the bonding method further includes electroplating or spraying the support plate 120 to form a second protective layer 121 (a coating of the support plate 120). In this case, the outer surface of the second protective layer 121 away from the main body of the support plate 120 serves as the outer surface of the support plate 120. Glue is applied to one of the outer surface of the first protective layer 114 and the outer surface of the second protective layer 121 to form an adhesive layer 130, and the first protective layer 114 and the second protective layer 121 are bonded to the other through the adhesive layer 130.

[0074] In this embodiment, the support plate 120 is made of a non-corrosion-resistant material such as ordinary carbon steel, and a second protective layer 121 is provided to enhance the corrosion resistance of the support plate 120. Figure 5 As shown, a coating can be sprayed on the outer surface of the support plate 120 to form a second protective layer 121 on the outer surface of the support plate 120, thereby completing the spray coating of the support plate 120. The second protective layer 121 is composed of coating material. In this way, the second protective layer 121 can protect the support plate 120 and improve the corrosion resistance of the support plate 120.

[0075] It is understandable that in other embodiments, the support plate may also be electroplated, and the second protective layer is an electroplated layer.

[0076] After the second protective layer 121 is formed on the support plate 120, the first protective layer 114 and the second protective layer 121 are disposed opposite each other. Glue is applied to form an adhesive layer 130 on one of the outer surfaces of the first protective layer 114 and the second protective layer 121, and the adhesive layer 130 is bonded to the other.

[0077] Optionally, for a support plate 120 that has been sprayed or electroplated, after step S3, the bonding strength between the adhesive layer 130 and the second protective layer 121 is less than the bonding strength between the second protective layer 121 and the body of the support plate 120. After step S3, the bonding strength between the adhesive layer 130 and the second protective layer 121 is less than the yield strength of the support plate 120.

[0078] In this way, when the support plate 120 is impacted and is about to separate from the panel 110, the adhesive layer 130 bonding the support plate 120 and the panel 110 is damaged earlier than the support plate 120, which facilitates repair (bonding the support plate 120 to the panel 110), avoids damage to the support plate 120 and the second protective layer 121, and reduces maintenance costs.

[0079] The bonding strength is the minimum force required to break the bond between the adhesive (herein, the adhesive layer 130) and a unit area (e.g., 1 square millimeter) of the interface of the bonded object (herein, the outer surface of the first protective layer 114 and the outer surface of the support plate 120). This force is perpendicular to the interface of the bonded object.

[0080] For example, the bonding strength between the adhesive layer 130 and the second protective layer 121 is the minimum force required to break the bonding connection between the adhesive layer 130 and the second protective layer 121 per unit area. The bonding strength between the adhesive layer 130 and the first protective layer 114 is the minimum force required to break the bonding connection between the adhesive layer 130 and the first protective layer 114 per unit area.

[0081] Adhesion strength is the minimum force required to peel off a coating adhered to a unit area (e.g., 1 square millimeter) of the adhered interface (e.g., the outer surface of the plate 110 to which the first protective layer 114 is attached, and the outer surface of the body of the support plate 120 to which the second protective layer 121 is attached). This force is perpendicular to the adhered interface.

[0082] For example, the adhesion strength between the second protective layer 121 and the support plate 120 is the minimum force required to peel off the second protective layer 121 attached to a unit area of the support plate 120. The adhesion strength between the first protective layer 114 and the plate 110 is the minimum force required to peel off the first protective layer 114 attached to a unit area of the plate 110.

[0083] The yield strength is the minimum stress value that causes permanent deformation of the object (plate 110 and support plate 120).

[0084] Optionally, step S1 includes:

[0085] After or before the panels 110 are assembled to form a container, the panels 110 are sprayed; after the panels 110 are sprayed with paint, the panels 110 are baked.

[0086] The panels 110 may be sprayed before being welded to form the housing 100 and / or the door 101. Alternatively, the panels 110 may be sprayed after being welded to form the housing 100 and / or the door 101. This facilitates the bonding process.

[0087] After the plate 110 is sprayed with paint, the plate 110 is baked for a preset baking time. The preset baking time can be set as needed. This can solidify the paint, thereby making the paint firmly adhere to the plate 110 and increasing the hardness of the paint.

[0088] In this embodiment, step S2 is performed after baking to avoid the high temperature of baking from melting the adhesive layer 130 and rendering the adhesive layer 130 ineffective.

[0089] Optionally, one of the adhesion strength between the first protective layer 114 and the panel 110, and the adhesion strength between the second protective layer 121 and the support plate 120 is σ1. At least one of the adhesion strength between the adhesive layer 130 and the second protective layer 121, and the adhesion strength between the adhesive layer 130 and the first protective layer 114 is σ2. σ1 > σ2 > 0.5 MPa. Thus, the adhesive connection strength between the panel 110 and the support plate 120 can meet the requirements of the container.

[0090] With σ1 > σ2, at least one of the bonding strength between adhesive layer 130 and second protective layer 121 and the bonding strength between adhesive layer 130 and first protective layer 114 is less than or equal to σ1. Thus, when support plate 120 is impacted and about to separate from plate 110, adhesive layer 130 is damaged before first protective layer 114 and second protective layer 121, facilitating repair.

[0091] Optionally, σ1≥6 MPa. Thus, the first protective layer 114 and the second protective layer 121 can meet the needs of the container.

[0092] Optionally, σ2≥5 MPa. That is, σ2≥5 MPa is required for at least one of the bonding strength between the adhesive layer 130 and the second protective layer 121 and the bonding strength between the adhesive layer 130 and the first protective layer 114. Thus, the adhesive layer 130 can meet the requirements of the container.

[0093] Optionally, after step S3, the bonding strength between the adhesive layer 130 and the first protective layer 114 is less than at least one of the adhesion strength between the first protective layer 114 and the plate 110 and the yield strength of the plate 110. In this manner, when the support plate 120 is impacted and about to separate from the plate 110, the adhesive layer 130 bonding the support plate 120 to the plate 110 is damaged before the plate 110, facilitating repair (bonding the support plate 120 to the plate 110), preventing damage to the plate 110 and the first protective layer 114, and reducing repair costs.

[0094] The present application also provides a container. The container is the aforementioned container. The container includes a panel 110 and a support plate 120. The panel 110 and the support plate 120 are bonded together using the aforementioned bonding method.

[0095] In this embodiment, the container includes a panel 110 and a support plate 120. The panel 110 and the support plate 120 are bonded together by the aforementioned bonding method. The support plate 120 is bonded to the panel 110 to avoid damaging the coating of the container due to welding the support plate 120 to the panel 110. There is no need for repair treatment such as repainting, which reduces the workload, increases the efficiency, and reduces the cost. In addition, deformation of the support plate 120 and the panel 110 caused by welding can also be avoided.

[0096] Alternatively, as Figures 1 to 4 As shown, the plate 110 is a corrugated plate. The plate 110 constitutes the inner surface of the wall body close to the center of the box body. The corrugated plate includes a groove 111. Located in the box body 100, the groove of the corrugated plate is recessed toward the outer side of the wall body away from the center of the box body 100. In the box door 101, the groove 111 is recessed toward the outer side of the box door 101 away from the center of the box body 100 (the side of the box door 101 away from the center of the box body 100 when the box door 101 closes the box opening). The support plate 120 is located in the groove 111. As a result, the space in the box body 100 occupied by the support plate 120 is reduced.

[0097] Alternatively, as Figures 1 to 4 As shown, the support plate 120 does not protrude from the groove 111. Thus, the support plate 120 disposed on the cabinet 100 does not protrude into the inner side of the groove 111 near the center of the cabinet 100. When the cabinet door 101 is closed, the support plate 120 disposed on the cabinet door 101 does not protrude into the inner side of the groove 111 near the center of the cabinet 100. This prevents the support plate 120 from occupying space within the cabinet 100.

[0098] like Figure 3 and Figure 4 As shown, the groove 111 has a bottom surface 112 and side surfaces 113. Along the width direction of the groove 111, the two ends of the bottom surface 112 are connected to the two side surfaces 113 respectively. The bottom surface 112 of the groove 111 is perpendicular to the depth direction of the groove 111 (that is, the thickness direction of the wall or door in which the groove is provided). For example, the depth direction of the groove 111 of the side wall is parallel to the width direction of the box body 100. The bottom surface 112 of the groove 111 of the side wall is perpendicular to the width direction of the box body 100.

[0099] The side surface 113 of the groove 111 is an inclined surface. Herein, the inclined surface is inclined in at least one of a vertical direction and a horizontal direction. The horizontal direction is parallel to the length direction and the width direction of the box body 100.

[0100] Specifically, the side surfaces 113 provided on the end walls and side walls are inclined in the longitudinal direction of the box body 100 and in the width direction of the box body 100. The side surfaces 113 provided on the groove 111 provided on the top wall are inclined in the vertical direction and in the longitudinal direction of the box body 100. The side surfaces 113 provided on the groove 111 provided on the door 101 are inclined in the vertical direction. When the door 101 is closed, the side surfaces 113 provided on the groove 111 provided on the door 101 are inclined in the longitudinal direction of the box body 100.

[0101] like Figure 2 and 3 As shown, the support plate 120 is adhered to the bottom surface 112 of the groove 111 through the adhesive layer 130 .

[0102] like Figures 1 to 4 As shown, the length direction of the groove 111 is parallel to the length direction of the support plate 120 disposed therein. The length direction of the groove 111 disposed on the side wall of the corrugated plate extends in the vertical direction. The length direction of the groove 111 disposed on the end wall of the corrugated plate extends in the vertical direction. The length direction of the groove 111 disposed on the top wall of the corrugated plate extends along the width direction of the box body 100. When the box door 101 is closed, the length direction of the groove 111 disposed on the corrugated plate of the door 101 extends along the width direction of the box body 100.

[0103] Second embodiment

[0104] like Figure 6 As shown, in the second embodiment, the support plate 220 is adhered to the side surface 213 of the plate 210 through the adhesive layer 230 .

[0105] The other configurations of the second embodiment are substantially the same as those of the first embodiment and will not be described again here.

[0106] Third embodiment

[0107] like Figure 7 As shown, in the third embodiment, the support plate 320 is adhered to the bottom surface 312 and the side surface 313 of the plate 310 through the adhesive layer 330 .

[0108] The other configurations of the third embodiment are substantially the same as those of the first embodiment and will not be described again here.

[0109] Fourth embodiment

[0110] In the fourth embodiment, if Figure 8 As shown, the support plate 420 is made of a corrosion-resistant material (such as stainless steel or aluminum alloy), and no electroplating or spraying is performed on the support plate 420. In other words, the support plate 420 is not provided with a second protective layer.

[0111] Optionally, for a support plate 420 that is not provided with a second protective layer, the outer surface of the body of the support plate 420 serves as the outer surface of the support plate 420. The first protective layer 414 of the panel 410 is directly bonded to the outer surface of the support plate 420 near the panel 410 via the adhesive layer 430. The bonding strength between the adhesive layer 430 and the support plate 420 is less than the yield strength of the support plate 420. In this way, when the support plate 420 is impacted and is about to separate from the panel 410, the adhesive layer 430 bonding the support plate 420 to the panel 410 is damaged before the support plate 420, facilitating repair (bonding the support plate 420 to the panel 410), preventing damage to the support plate 420, and reducing repair costs.

[0112] The bonding strength between the adhesive layer 430 and the support plate 420 is the minimum force required to break the bonding connection between the adhesive layer 430 and the support plate 420 per unit area.

[0113] The bonding strength σ2 between the adhesive layer 430 and the support plate 420 is greater than or equal to 5 MPa.

[0114] The other configurations of the fourth embodiment are substantially the same as those of the first embodiment and will not be described again here.

[0115] The present application has been described through the above-described embodiments, but it should be understood that the above-described embodiments are for illustrative and illustrative purposes only and are not intended to limit the present application to the described embodiments.
