Description

Technical Field

[0001] This application belongs to the technical field of composite board processing equipment, and more specifically, it relates to an integrated machine for coating and laminating aluminum foil onto boards. Background Technology

[0002] Due to the demand for housing heating projects, underfloor heating systems are widely used in modern housing, especially in northern housing structures. Existing underfloor heating systems typically have heat exchange pipes arranged at set intervals and supports for these pipes. In order to reliably support the pipes and also provide insulation to reduce or prevent heat loss to the floor slab, the applicant has developed an aluminum foil coating and laminating machine to laminate a layer of aluminum foil onto a flame-retardant foam board to create a composite board, which serves as the support for the heat exchange pipes of the underfloor heating system.

[0003] This aluminum foil coating and laminating machine is an advanced sheet metal processing equipment that integrates coating, laminating, and cutting functions. It employs hot-melt adhesive technology to evenly and precisely coat the aluminum foil surface, then uses laminating rollers to tightly bond the aluminum foil to the sheet metal. During the lamination process, the machine uses precise pressure control to ensure a strong bond between the aluminum foil and the sheet metal, achieving a high-quality lamination effect. Since the sheet metal is a single sheet with a set length, it is conveyed intermittently during lamination with the aluminum foil, while the aluminum foil is continuously unwound. Therefore, after laminating the sheet metal with the aluminum foil, the aluminum foil connecting the front and back sheets needs to be cut at the junction of the sheets. Because the sheet metal has straight grooves to accommodate heat exchange tubes, at least a portion of the aluminum foil also needs to be laminated within these grooves. Summary of the Invention

[0004] The purpose of this application is to provide an integrated machine for coating and laminating aluminum foil onto sheet metal, which can efficiently and automatically process composite sheets used for underfloor heating, thereby solving the problem of the lack of automated processing equipment for such composite sheets in the prior art.

[0019] Furthermore, the traction device includes an automatic wire rope retractor 115 and a column 116;

[0020] The automatic wire rope retractor 115 is fixed in position and arranged opposite to the support 104 on both sides of the crossbeam 103. The column 116 is installed on the crossbeam 103 and connected to the wire rope that can be automatically retracted by the automatic wire rope retractor 115.

[0030] The beneficial effects of the sheet metal and aluminum foil coating and laminating machine provided in this application are as follows: Compared with the prior art, the sheet metal and aluminum foil coating and laminating machine provided in this application is equipped with a cross-cutting device. The cross-cutting device includes a crossbeam, a support, and a stop bar, which are arranged sequentially and at intervals along the conveying direction of the intermediate conveyor belt. When the sheet metal is conveyed to the point where it abuts against the support, it can drive the support and the crossbeam connected to the support to move forward together. During this process, the cross-cutting blade has sufficient time to move along the crossbeam and perform transverse cutting of the aluminum foil. When the sheet metal continues to be conveyed to the point where the flipping plate connected to the support abuts against the stop bar, the arc-shaped tilt at the front end of the flipping plate will continue to act with the stop bar and lift the support, thereby separating it from the sheet metal. Due to the loss of the resistance from the sheet metal, the traction device will automatically activate and cause the crossbeam connected to the traction device and the support connected to the crossbeam to automatically reset in the opposite direction, thereby facilitating the continued transverse cutting of subsequent aluminum foil. Therefore, the sheet metal and aluminum foil coating and laminating machine provided in this application can effectively realize the automated operation of transverse cutting of aluminum foil, which is far superior to the prior art.

[0043] Please refer to the following: Figures 1 to 6 The present application provides a description of an integrated sheet metal and aluminum foil coating and laminating machine. This integrated sheet metal and aluminum foil coating and laminating machine includes: an intermediate conveyor belt 101, a coating and laminating device 102, a cross-cutting device, a traction device, and a rear conveyor belt 400.

[0044] The intermediate conveyor belt 101 is used to transport the sheet metal 200.

[0045] The coating and laminating device 102 is located above the conveying direction of the intermediate conveyor belt 101 and includes at least an unwinding shaft 1021, a coating die head 1022, a coating roller 1023, a coating pressure roller 1024, and a laminating pressure roller 1025. It is used to apply adhesive to the surface of the aluminum foil 600 unwound by the unwinding shaft 1021 and laminate it to the surface of the board 200.

[0046] A typical coating roller 1023 is rotatably mounted on a frame wall plate 700 that serves as an integral support. A coating die 1022 is positioned opposite to the coating roller 1023 on one side, and a coating pressure roller 1024 is positioned opposite the coating die 1022 on the other side of the coating roller 1023. The axes of the coating pressure roller 1024 and the coating roller 1023 are parallel, and the coating pressure roller 1024 can be positioned relatively far away from or close to the coating roller 1023. An unwinding shaft 1021 is mounted on the frame wall plate 700 and located above the coating pressure roller 1024. Generally, the mounting and driving methods of the coating roller 1023 and the coating pressure roller 1024 can adopt the structure of existing coating machinery. Roller 1025 is positioned below coating roller 1023 and close to intermediate conveyor belt 101. Specifically, both ends of the laminating roller 1025 are rotatably mounted on slider 701. Slider 701 is guided up and down by guide rail 702 on frame wall plate 700. The upper end of slider 701 is connected to piston rod end of cylinder 800, so that laminating roller 1025 can move away from or press towards intermediate conveyor belt 101. In this way, through the action of laminating roller 1025, the coated aluminum foil 600 can be pressed and continuously adhered to the plate 200, and the aluminum foil 600 is laminated onto the entire plate 200 surface during the clamping and conveying of intermediate conveyor belt 101 and laminating roller 1025.

[0047] According to the structure provided in this embodiment, after the aluminum foil 600 is unwound from the unwinding shaft 1021, it is guided between the coating roller 1024 and the coating roller 1023, and adhesive is applied to the surface of the coating roller 1023 through the coating die 1022. Then, it is guided below the laminating roller 1025. Simultaneously, the sheet material 200 is conveyed to the area below the laminating roller 1025 by the intermediate conveyor belt 101. At this time, the adhesive-coated side of the aluminum foil 600 contacts the upper surface of the sheet material 200. The aluminum foil 600 coated with adhesive is laminated onto the upper surface of the plate 200 conveyed by the intermediate conveyor belt 101 by the pressure of the laminating roller 1025. The plate 200 with aluminum foil 600 is forced forward under the clamping and conveying of the intermediate conveyor belt 101 and the laminating roller 1025. Here, the coating die head 1022 can be a coating die head of the prior art, and it is understood that the coating die head 1022 is connected to an adhesive supply device to complete the continuous supply of adhesive.

[0048] The cross-cutting device includes a guide platform 500 connected to the output end of the intermediate conveyor belt 101, and crossbeams 103, supports 104, and bumpers 105 arranged sequentially at intervals along the traveling direction of the plate 200. The crossbeams 103 are horizontally positioned above the guide platform 500 and connected to a cross-cutting blade 106 that can move along the crossbeams 103. The distance between the supports 104 and the crossbeams 103 is adapted to the length of the plate 200. A follower rod 107 connects the supports 104 and the crossbeams 103. The follower rod 107 is hinged to the crossbeams 103 and can rotate around its hinge axis with respect to the crossbeams 103. The support 104 is also connected to a flipping plate 108 with an arc-shaped protrusion at the front end; the support 104 is used to abut against the front end of the plate 200 under its own weight and to be driven by the plate 200 to make the crossbeam 103 follow the plate 200 along the guide platform 500; it is also used to gradually lift up and separate from the front end of the plate 200 during the process of the flipping plate 108 abutting against the bumper 105; the cross cutter 106 is used to cut the aluminum foil 600 covered on the plate 200 laterally from the junction between the front and rear plates 200 when the crossbeam 103 follows the plate 200.

[0049] The traction device is connected to the crossbeam 103 and is used to automatically reset the crossbeam 103 in the opposite direction of the traveling direction of the plate 200 after the support 104 and the front end of the plate 200 are disengaged.

[0050] The rear conveyor belt 400 is connected to the end of the material guiding platform 500, and the conveying speed of the rear conveyor belt 400 is greater than the conveying speed of the middle conveyor belt 101.

[0051] According to the structure provided in this embodiment, the aluminum foil coating and laminating machine provided in this embodiment is equipped with a cross-cutting device. The cross-cutting device includes a crossbeam 103, a support 104, and a contact bar 105, which are arranged sequentially and at intervals along the conveying direction of the intermediate conveyor belt 101. When the sheet 200 coated with aluminum foil 600 is conveyed to abut against the support 104, it can drive the support 104 and the crossbeam 103 connected to the support 104 to move forward together. During this process, the cross-cutting blade 106 has sufficient time to move along the crossbeam 103 and perform transverse cutting of the aluminum foil 600. It can be understood that since the distance between the support 104 and the crossbeam 103 is adapted to the length of the sheet 200, when the front end of the sheet 200 abuts against the support 104, the cross-cutting blade 106 can move forward together. The cutter 106 is positioned precisely at the intersection of two sheets 200 covered with aluminum foil 600. When the cutter 106 transversely cuts the aluminum foil 600 at this point, the two sheets 200 become individual finished sheets for easy collection and packaging. As the sheet 200 continues to be conveyed to the support 104, where it abuts against the flipping plate 108 and the contact rod 105, the curved tip of the flipping plate 108 continuously interacts with the contact rod 105, causing... The support 104 is raised, thereby separating it from the front end of the plate 200 and placing it on the upper surface of the plate 200. Due to the loss of the resistance from the plate 200, the traction device will automatically activate and cause the crossbeam 103 connected to the traction device and the support 104 connected to the crossbeam 103 to automatically reset in the opposite direction. At this time, the previous plate 200 covered with aluminum foil 600 is quickly transported away by the rear conveyor belt 400, creating a distance between it and the next plate 200 covered with aluminum foil 600. Thus, the support 104 falls back to a position that can block the next plate 200 due to its own weight, thereby facilitating the continued transverse cutting of the subsequent aluminum foil 200. When the front end of the next plate 200 covered with aluminum foil 600 abuts against the support 104, another transverse cutting action begins, and so on automatically. The plate and aluminum foil coating and laminating integrated machine provided by this embodiment can effectively realize the automated operation of transverse cutting of aluminum foil, which is far superior to the prior art. In addition, as mentioned above, since the distance between the support 104 and the crossbeam 103 in this embodiment is adapted to the plate 200, when the plate 200 abuts against the support 104, the cross-cutting blade 106 can avoid cutting the plate 200, and only the aluminum foil covering the surface of the plate 200 is cut.

[0052] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6The cross-cutting device also includes a buffer positioning head 109 for buffering and positioning; the buffer positioning head 109 is disposed at a predetermined position on the guide platform 500 and is used to receive the crossbeam 103 during the automatic reset process. According to the structure provided in this embodiment, the buffer positioning head 109 can, on the one hand, buffer the automatically reset crossbeam 103, avoiding the crossbeam 103 from bearing large impact forces during the reset process, which is beneficial to maintaining the stability of the crossbeam 103 structure. On the other hand, it can also position the crossbeam 103, thereby ensuring that the crossbeam 103 remains in the same position after each reset, which is beneficial to better adapting to the plate 200 and ensuring the smooth progress of the cross-cutting process.

[0053] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The cross-cutting device also includes a pneumatic sliding table 110 mounted on the crossbeam 103. The cross-cutting blade 106 is connected to the pneumatic sliding table 110 and is driven to move laterally by the pneumatic sliding table 110. A control switch linked to the pneumatic sliding table 110 is provided on the support 104. The control switch is used to activate the device after the front end of the plate 200 abuts against the side wall of the support 104. According to the structure provided in this embodiment, since the support 104 is provided with the control switch of the pneumatic sliding table 110, the control switch can be triggered when the plate 200 and the support 104 abut, thereby enabling the cross-cutting blade 106 to start cross-cutting the aluminum foil and complete the cross-cutting process, which is beneficial to further improve the automation level of the cross-cutting process. It is understood that the pneumatic sliding table 110 in this embodiment can also be replaced by an electric sliding table, which has the same technical effect and will not be described in detail. The control switch can adopt existing micro switches, inductive switches, and position sensors. It is understood that the position of the control switch can also be set at other positions that can detect the abutment state of the plate 200 and the support 104.

[0054] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The support 104 is equipped with a roller 111 at its bottom front end. The roller 111 is used to roll and engage with the surface of the guide platform 500 or the plate 200 when the support 104 moves or resets. According to the structure provided in this embodiment, when the support 104 falls onto the guide platform 500 due to its own weight, it can roll and engage with the guide platform 500 through the roller 111, thereby avoiding scratching the guide platform 500. At the same time, it also makes the plate 200 smooth when pushing the support 104 to move. Furthermore, when the cross-cutting device retracts and resets, the support 104 will pass over the upper surface of the previous plate 200 covered with aluminum foil 600, which has been separated. In this way, the roller 111 also avoids scratching the aluminum foil covered on the plate 200, ensuring the quality of the finished plate 200.

[0055] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6The flipping plate 108 is provided with an adjustment groove 112 extending along the conveying direction of the intermediate conveyor belt 101. The support 104 is adjustablely connected to the flipping plate 108 through the adjustment groove 112. Typically, the support 104 is connected to the flipping plate 108 by fasteners (such as bolts) passing through the adjustment groove 112. Thus, according to the structure provided in this embodiment, the distance between the support 104 and the crossbeam 103 can be adjusted by using the adjustment groove 112, thereby better adapting to the plate 200 or enabling the cutting position of the aluminum foil 600 to better meet production needs, and has a flexible use effect.

[0056] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The cross-cutting device also includes guide rails 113 arranged on both sides of the guide platform 500 and extending along the conveying direction of the sheet 200, and slide blocks 114 slidably connected to the guide rails 113; the two ends of the crossbeam 103 are connected to the slide blocks 114 and slidably connected to the guide rails 113 through the slide blocks 114. According to the structure provided in this embodiment, since the crossbeam 103 is connected to the slide blocks 114 and slidably connected to the guide rails 113 through the slide blocks 114, the crossbeam 103 can move stably along the conveying direction of the sheet 200 under the guidance of the guide rails 113, which is beneficial to ensuring the stability of the cross-cutting process. In addition, in this embodiment, the guide rails 113 are arranged on both sides of the guide platform 500, which is beneficial to further improve the stability of the cross-cutting process.

[0057] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The traction device includes an automatic wire rope retractor 115 and a column 116. The automatic wire rope retractor 115 is fixed in position and arranged opposite to the support 104 on both sides of the crossbeam 103. The column 116 is installed on the crossbeam 103 and connected to the wire rope that can be automatically retracted by the automatic wire rope retractor 115.

[0058] According to the structure provided in this embodiment, when the crossbeam 103 moves along the conveying direction of the intermediate conveyor belt 101 driven by the support 104, the wire rope in the automatic wire rope retractor 115 can be pulled out and extended, and always maintains its connection with the crossbeam 103; when the support 104 detaches from the plate 200, the wire rope in the automatic wire rope retractor 115 will automatically retract, thereby driving the crossbeam 103 to move in the opposite direction of the conveying direction of the intermediate conveyor belt 101, and then automatically reset, with a good and stable retraction effect. Here, the automatic wire rope retractor 115 can be a commercially available product, and the appropriate model can be selected according to the required reset pull force; of course, the automatic wire rope retractor 115 can also be replaced by other devices with linear drive function, which have the same technical effect, and will not be described in detail here.

[0059] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6The sheet 200 has several transversely distributed straight grooves 201. The sheet aluminum foil coating and laminating machine also includes multiple longitudinal cutters 117 mounted above the guide platform 500 and corresponding to the straight grooves 201. The longitudinal cutters 117 are arranged between the coating and laminating device 102 and the transverse cutting device along the conveying direction of the sheet 200. The longitudinal cutters 117 are used to longitudinally cut the aluminum foil 600 laminated on the sheet 200 along the centerline of the straight grooves 201. The machine also includes a rotating shaft 118 mounted between the crossbeam 103 and the support 104. The rotating shaft 118 is axially connected with a number of pressure rollers 119, and the positions of the pressure rollers 119 correspond one-to-one with the straight grooves 201. The follower rod 107 is located above the rotating shaft 118, and the rotating shaft 118 is located outside the movement trajectory range of the crossbeam 103 and the support 104. The pressure rollers 119 are used to press the broken ends of the aluminum foil 600 longitudinally cut at the opening of the straight groove 201 into the corresponding straight groove 201.

[0060] According to the structure provided in this embodiment, the multiple longitudinal cutters 117 can longitudinally cut the aluminum foil corresponding to the straight grooves 201 on the plate 200. Thus, when the straight grooves 201 pass through the pressure rollers 119, the cut ends of the aluminum foil 600 longitudinally cut at the opening of the straight grooves 201 can be pressed tightly against the side wall of the straight grooves 201 under the action of the pressure rollers 119. This effectively avoids the problem of voids forming in the straight grooves 201 and can also improve the tightness of the structure between the aluminum foil 600 and the plate 200.

[0062] According to the structure provided in this embodiment, the hopper 120 can be used to stack multiple layers of plates 200. Under the conveying action of the front conveyor belt 300, the plates 200 at the bottom layer can be conveyed forward sequentially through the gap between the front baffle 121 and the front conveyor belt 300, achieving a good automatic conveying effect. In addition, the brake lever 122 provided in this embodiment can be raised and lowered by the lifting mechanism, so that the flange 123 connected to the brake lever 122 can enter or leave the straight groove 201 provided on the plate 200. On the one hand, this helps to control the conveying interval of the plates 200, ensuring that the plate and aluminum foil coating and laminating integrated machine provided in this embodiment can perform coating and laminating of aluminum foil 600 normally and orderly. On the other hand, it can also guide the plates 200, so that the plates 200 can be conveyed forward in the same preset posture, which helps to improve product quality.

[0063] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The integrated aluminum foil coating and laminating machine also includes a collection trolley 124 located at the discharge end of the rear conveyor belt 400.
