[0050] The application will be further described in conjunction with the drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the application and not to limit the scope of the application. In addition, it should be understood that those skilled in the art can make various modifications or changes to the application after reading the content of the application, and these equivalent forms also fall within the scope defined by the application. Embodiment 1

[0051] The embodiment provides a box plate connecting profile, which refers to the drawings shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 .

[0052] The box plate connecting profile of the embodiment mainly comprises a bottom plate 12, a cover plate 13, a rubber strip 14 and a film glue 15. The bottom plate 12 serves as a main support and has a U-shaped structure with a downward recess in the middle. The cover plate 13 is attached to the upper part of the bottom plate 12, and a 180° bending edge is arranged at the lower part of the cover plate 13 on both sides. The bottom plate 12 is covered in the bending space of the bending edge, so that the bottom plate 12 and the cover plate 13 become a firm profile as a whole, which can be used for connecting the box plates in the container.

[0053] In the embodiment, the film glue 15 is attached to the upper surface of the cover plate 13 for protection. The film glue 15 serves as a protective layer and can prevent the profile from being damaged in appearance during processing or transportation. The film glue 15 can be directly torn off after the profile is used. The rubber strip 14 is also attached to the bending edge on both sides of the cover plate 13. When the box plate is connected to the profile, it is installed at the position of the rubber strip 14, and the sealing after connection is realized through the rubber strip 14.

[0054] In a specific embodiment provided in the embodiment, a plurality of long holes 17 arranged at a certain interval are arranged at the middle of the bottom plate 12, i.e. the U-shaped groove. The long holes 17 can reduce the weight of the profile without affecting the strength of the profile, and other components can also be installed after connecting the box plate. At the same time, a riveting round hole 16 is arranged on both sides of the profile, and the box plate can be directly connected to the profile by means of rivets, avoiding drilling operations on the construction site.

[0055] In a specific embodiment provided in the embodiment, the material of the bottom plate 12 is a surface galvanized plate, which is beautiful, rust-proof and corrosion-resistant. The cover plate 13 is a double-sided color-coated plate, which has a good surface effect and is resistant to rain and corrosion.

[0056] The box plate connecting structure of the above embodiment has the advantages of lightweight and high strength, and has good performance in appearance, durability and practicability. Embodiment 2

[0057] The embodiment provides a roll composite forming production line of a box plate connecting profile, which is mainly used for producing the box plate connecting profile in the embodiment 1. The whole production line is automatically controlled, and one person can operate the production line. The production line can directly output the finished box plate connecting profile, and the production is efficient and fast, and the produced profile has high quality and good effect.

[0058] Reference Figure 6 As shown in the figure, the roll composite forming production line provided by the embodiment mainly comprises a bottom plate feeding mechanism 2, a bottom plate punching mechanism 1, a cover plate feeding mechanism 3, a bottom plate roll forming mechanism 4, a film covering mechanism 5, a cover plate roll forming mechanism 6, a detection mechanism 7, a composite forming mechanism 8, a rubber bonding mechanism 9, a composite profile punching mechanism 10 and a cutting mechanism 11.

[0059] The bottom plate feeding mechanism 2 has a rack, and the plate material used for processing the bottom plate 12 adopts a long strip flat plate structure and is installed in a roll on the bottom plate feeding mechanism 2 and is conveyed to the bottom plate punching mechanism 1. The bottom plate plate material can be positioned and punched at the position of the bottom plate punching mechanism 1, wherein the bottom plate punching mechanism 1 comprises two stations and is respectively used for processing a long strip hole 17 and a cutting process hole 18. During the conveying process, the bottom plate plate material passes through the bottom plate punching mechanism 1, the bottom plate punching mechanism 1 sequentially and interval punches in the middle position of the bottom plate plate material by punching to form the long strip hole 17, and in another punching station, the bottom plate punching mechanism 1 sequentially and interval punches in the two side positions of the bottom plate plate material by punching to form the cutting process hole 18. In the subsequent steps, the middle of the bottom plate plate material needs to be roll-formed into a U-shaped groove structure, so that in the subsequent cutting, due to the high strength of the U-shaped groove structure, the cutting is laborious and the cut part is easy to be uneven. By processing the cutting process hole 18 (as shown in the figure) at the bottom plate punching mechanism 1, the cutting process hole 18 is located at the two edge positions of the U-shaped groove after the bottom plate plate material is roll-formed, and the cutting process hole 18 can be cut during the subsequent cutting. The setting of the cutting process hole 18 can reduce the structural strength of the position and facilitate the cutting. Figure 5

[0060] After the bottom plate plate material passes through the bottom plate punching mechanism 1, the bottom plate plate material enters the bottom plate roll forming mechanism 4 for roll forming. The bottom plate roll forming mechanism 4 comprises six groups of bottom plate roll forming wheel groups 41, and the bottom plate plate material sequentially passes through the six groups of bottom plate roll forming wheel groups 41 and is roll-formed. Each group of bottom plate roll forming wheel groups 41 comprises two roll forming wheels, and the bottom plate plate material is gradually roll-formed through the change of the shape and gap between the roll forming wheels, and finally a U-shaped groove downwardly recessed is formed in the middle of the bottom plate plate material. Referring to the figure, it is a schematic view of the shape change of the bottom plate plate material after passing through each group of bottom plate roll forming wheel groups 41. After the bottom plate plate material is formed, the bottom plate plate material is conveyed backward to enter the composite forming mechanism 8. Figure 9

[0061] ​​The cover plate feeding mechanism 3 of the embodiment has the same principle as the bottom plate feeding mechanism 2. The cover plate material in roll is placed on the cover plate feeding mechanism 3 and is conveyed to the cover plate roller forming mechanism 6. The cover plate roller forming mechanism 6 includes seven cover plate roller forming wheel groups 61. The cover plate material passes through the seven cover plate roller forming wheel groups 61 in sequence and is formed by roller pressing. Each cover plate roller forming wheel group 6 includes two roller pressing wheels. The cover plate material is gradually pressed by the change of shape and gap between the roller pressing wheels. Finally, the bending edges of 90° downward are formed on both sides of the cover plate material. Referring to FIG. 7, it is a schematic diagram of the shape change of the cover plate material after passing through each cover plate roller forming wheel group 61. After passing through the cover plate roller forming mechanism 6, the cover plate material is also sent to the composite forming mechanism 8. Figure 10

[0062] The composite forming mechanism 8 of the embodiment is mainly used for the composite of the cover plate material and the bottom plate material, so that they become a firm whole. When the cover plate material and the bottom plate material enter the composite forming mechanism 8, the cover plate material is located at the upper part and the bottom plate material is located at the lower part. Because the cover plate material has the bending edges of 90° downward on both sides, the bottom plate material falls into the inside of the bending edges on both sides. The cover plate material and the bottom plate material are roller formed at the composite forming mechanism 8. The composite forming mechanism 8 includes eight composite roller forming wheel groups 81. The cover plate material and the bottom plate material pass through the eight composite roller forming wheel groups 81 in sequence and are formed by roller pressing. Each composite roller forming wheel group 81 includes two roller pressing wheels. The cover plate material is gradually pressed by the change of shape and gap between the roller pressing wheels. The bending edges on both sides of the cover plate material are gradually pressed and bent from 90° to 180°. Finally, the bottom plate material is firmly covered in the bending edges. Referring to FIG. 8, it is a schematic diagram of the change of the plate material when passing through each composite roller forming wheel group 81 during the composite roller pressing. After passing through the composite forming mechanism 8, the plate material forms the composite profile 19 of the cover plate material and the bottom plate material. Figure 11

[0063] In one specific embodiment provided by the embodiment, the production line can also complete the pasting of the film adhesive 15 at one time. The pasting of the film adhesive 15 is completed by the film covering mechanism 5. The film covering mechanism 5 is arranged between the cover plate feeding mechanism 3 and the cover plate roller forming mechanism 6, that is, the cover plate material is covered with film before being formed, so as to avoid the surface damage in the subsequent processing process. The film covering mechanism 5 is further described in the following embodiments.

[0064] In one specific embodiment provided by the embodiment, the production line can also complete the pasting of the adhesive tape 14 at one time. The pasting of the adhesive tape 14 is completed by the adhesive pasting mechanism 9. The adhesive pasting mechanism 9 is arranged behind the composite forming mechanism 8. The adhesive tape 14 is pasted on the lower surface of the bending edges on both sides of the cover plate material when the composite profile 19 is conveyed backward. The adhesive pasting mechanism 9 is further described in the following embodiments.

[0065] ​​In a specific embodiment provided in the present embodiment, the production line is further provided with a detection mechanism 7, which is arranged in front of the composite molding mechanism 8 and is used for detection before the composite molding of the cover plate and the bottom plate, to ensure the synchronization of the two during conveying and prevent the cover plate and the bottom plate from being wrinkled or wavy during the holding, thereby improving the composite molding quality. The detection mechanism 7 of the present embodiment mainly includes a laser range finder 71 and a control system, as shown in Figure 19 The detection mechanism 7 is provided with conveying rollers, and the bottom plate is conveyed backward on the conveying rollers, while the cover plate is in a suspended state without support at this position and will be concave downward to form a certain arc under its own gravity. When the conveying speed of the cover plate is fast, the arc formed by the cover plate will be large, and when the conveying speed of the cover plate is slow, the arc formed by the cover plate will be small. By using this performance, the laser range finder 7 is arranged above the cover plate to measure the height at the arc. When there is material accumulation, the arc will be large, and the measured height data will also be large, and vice versa. The laser range finder 7 feeds back the data to the control system, and the control system controls the conveying motor of the cover plate roll forming mechanism 6 to control the conveying speed of the cover plate through a PID control algorithm. The change in the conveying speed leads to the change in the height data, and by controlling the height data to be kept in a set interval at all times, the synchronous conveying of the cover plate and the bottom plate can be ensured. The set data interval can be obtained through on-site trial and debugging.

[0066] In the present embodiment, after the composite profile with the film adhesive 15 and the adhesive strip 14 is obtained through the above process, the profile enters the subsequent composite profile punching mechanism 10, and the punching of the riveting circular hole 16 can be completed at the composite profile punching mechanism 10. The processed riveting circular hole 16 penetrates the film adhesive 15, the cover plate, the bottom plate and the adhesive strip 14 and can be used for installing a box plate. At the composite profile punching mechanism 10, servo tracking punching is adopted, and the punching mechanism can run synchronously with the profile to realize non-stop punching operation.

[0067] After the profile is punched with the riveting circular hole 16, the profile can be cut according to the required length. The cutting of the profile is completed by the cutting mechanism 11, which also adopts servo tracking cutting, and the cutting mechanism can run synchronously with the profile to realize non-stop cutting operation. The profile after cutting is the finished product. Embodiment 3

[0068] The present embodiment provides a film covering mechanism 5, which is mainly used for pasting a protective film adhesive 15 on the upper surface of the cover plate under non-stop state. Referring to Figure 12 , Figure 13 , Figure 14 and Figure 15 .

[0069] The film covering mechanism 5 mainly comprises an L-shaped support plate 53. The related parts are arranged on the inner side of the vertical plate of the support plate 53. A first material guide wheel 55 is arranged at the front end of the support plate 53. The bottom plate is first guided by the first material guide wheel 55 in the production process and enters the film covering mechanism 5. A second material guide wheel 56 is arranged at the rear end of the support plate 53 and is used for guiding the rear end of the cover plate. The cooperation of the first material guide wheel 55 and the second material guide wheel 56 makes the plate pass through the film covering mechanism 5 according to the set route. As a preferred scheme of the embodiment, the first material guide wheel 55 and the second material guide wheel 56 are provided with guide grooves for guiding the plate, and the first material guide wheel 55 is higher than the second material guide wheel 56 so that the plate is inclined downward for film covering operation.

[0070] A film pressing lower wheel 54 is arranged between the first material guide wheel 55 and the second material guide wheel 56. The plate passes through the film pressing lower wheel 54 in the conveying process, and the film covering operation is performed at the film pressing lower wheel 54. A film hanging wheel 59 is arranged at the upper part of the support plate 53. The film glue roller is installed on the film hanging wheel 59. The film glue 15 is guided to the upper side of the film pressing lower wheel 54 by the first film guide roller 510 and the second film guide roller 511. The film glue 15 is pressed on the upper surface of the plate by the rubber film pressing roller 85 of the pneumatic film pressing assembly 58.

[0071] In the above structure of the embodiment, the specific principle is that the plate is continuously conveyed by the guidance of the first material guide wheel 55 and the second material guide wheel 56 and passes through the film pressing lower wheel 54. The film glue 15 is introduced to the film pressing lower wheel 4 by the first film guide roller 510 and the second film guide roller 511 and is located on the upper part of the plate. The film glue 15 and the plate are pressed tightly at the film pressing lower wheel 54 by the rubber film pressing roller 85. With the conveying of the plate, the film glue 15 is automatically and continuously attached to the upper surface of the plate.

[0072] Directly using the above structure for film covering, it is verified by practice that air bubbles are easily generated between the film glue 15 and the plate. Therefore, in the embodiment, a material supporting roller 57 is arranged between the film pressing lower wheel 54 and the second material guide wheel 56. The seat bodies at both ends of the material supporting roller 57 are installed in the form of a long hole, so that the height of the material supporting roller 57 can be adjusted, and the upward supporting force of the material supporting roller 57 from the lower part to the plate can be adjusted. The plate has an upward tension force behind the film covering position. In cooperation with the stress of the plate at the film pressing lower wheel 54, the film glue 15 and the plate at the film pressing position can be tightly attached through debugging, so that the problem of air bubbles is solved.

[0073] As a preferred scheme of the embodiment, a diffuse reflection switch can be arranged between the first film guide roller 510 and the second film guide roller 511 to detect the film glue 15. If the film glue 15 is broken, an early warning can be given in time.

[0076] The embodiment provides a gluing mechanism 9, which is mainly used for gluing rubber strips 14 on both sides of the lower surface of a profile under a non-stop state.

[0077] Referring to Figure 16 , Figure 17 and Figure 18 .

[0078] The main structure of the gluing mechanism 9 in this embodiment is as follows: including a base 93, a tray 94, an inlet lower tension wheel 95, an inlet upper tension wheel 97, a guide wheel 96, a material supporting wheel group, and a paper separating wheel group, wherein the above-mentioned components mounted on the base 93 are arranged on both sides of the base 93, so that the gluing of the profile on both sides of the lower surface can be completed at one time; the disc-shaped adhesive belt wheel is mounted on the lower tray 94, the adhesive belt is composed of the rubber strip 14 and the paper 913, the adhesive belt enters the guide wheel 96 between the inlet lower tension wheel 95 and the inlet upper tension wheel 97, at the position of the guide wheel 96, the rubber strip 14 and the paper 913 are separated, wherein the paper 913 enters the paper separating wheel group backward, and the paper 913 is continuously discharged under the driving of the paper separating wheel group, the rubber strip 14 enters the material supporting wheel group, and the composite profile 19 moves backward at the material supporting wheel group in the production line, in the movement process, the rubber strip 14 is automatically glued to the lower surface of the composite profile 19.

[0079] Referring to the drawings, in the present embodiment, the material feeding lower tension wheel 95 is located below the material feeding upper tension wheel 97, and the material feeding lower tension wheel 95 exerts force upward on the material feeding upper tension wheel 97, so as to realize the guiding of the rubber strip 14 through the clamping force of the two and the guide groove provided on the wheel body. In the present embodiment, the material feeding lower tension wheel 95 is connected to one end of a swing rod 915, the swing rod 915 is hingedly connected to the base 93 in the middle, and the other end is suspended. A counterweight can be installed on the suspended end to adjust the pressing force, or the counterweight can not be installed according to the actual situation, but rely on the gravity of the swing rod 915 itself. When it is necessary to replace the rubber belt wheel and comb the rubber belt, the outer end of the swing rod 915 can be directly lifted upward, so that the material feeding lower tension wheel 95 is opened downward.

[0080] The rubber paper separation wheel set provided in the present embodiment mainly includes a rubber paper separation upper pressing wheel 911 and a rubber paper separation lower supporting wheel 912. The rubber paper separation upper pressing wheel 911 adopts a liftable structure, and the rubber paper separation lower supporting wheel 912 is used to provide power and is connected with a servo motor 914. The servo motor 914 controls the rotation of the rubber paper separation lower supporting wheel 912, so as to pull the rubber paper waste backward for conveying. The servo motor 914 continuously adjusts the speed following the speed change of the main motor of the equipment, so as to prevent the rubber paper 913 from being pulled off.

[0081] In the present embodiment, referring to the drawings, the material supporting wheel set mainly includes three material supporting wheels, namely, a front lower material supporting wheel 98, a rear lower material supporting wheel 99 and an upper material supporting wheel 910. The rear lower material supporting wheel 99 is arranged behind the front lower material supporting wheel 98, and the upper material supporting wheel 910 is arranged above the rear lower material supporting wheel 99. The front lower material supporting wheel 98 and the rear lower material supporting wheel 99 are provided with grooves 916 for the rubber strip 14 to pass through. When the composite profile 19 is conveyed, it passes through the gap between the rear lower material supporting wheel 99 and the upper material supporting wheel 910 and is limited. Since the composite profile 19 passes through the front lower material supporting wheel 98 first, and the rubber strip 14 is also introduced to the front lower material supporting wheel 98, the rubber strip 14 is attached to the lower surface of the composite profile 19 at the front lower material supporting wheel 98 during the movement of the composite profile 19. When the profile with the rubber strip 14 moves to the gap between the rear lower material supporting wheel 99 and the upper material supporting wheel 910, the rubber strip 14 is pressed on the lower surface of the profile, so as to ensure the firmness of the attached rubber strip 14.
