Description

Technical Field

[0001] This utility model relates to the field of hot pressing of composite materials, specifically to a heating roller protection device for metal composite plates. Background Technology

[0002] Metal composite panels refer to panels with one metal layer covered with another, aiming to save resources and reduce costs without compromising performance. When two or more panels of different metal materials are joined together under high temperature and pressure, multiple guide rollers are required. However, the guide rollers may not rotate smoothly during use, and adjacent guide roller groups may experience different tensions. This can lead to deformation of the metal composite panels when pulled between guide roller groups. If the guide rollers do not rotate smoothly, uneven tension on the aluminum plates makes them more prone to deformation and even breakage. Furthermore, during the lamination process, the metal plates need to be heated and coated with adhesive. Currently, this is generally done using heated pressure rollers, which have complex structures and increase costs. During the initial rolling process, adhesive needs to be applied to one metal plate before quickly bonding it to another. Therefore, the pressure rollers need to be adjusted to be close to the adhesive application position. Currently, pressure rollers are generally fixed in one position, making positional adjustment impossible and affecting the lamination effect. Utility Model Content

[0006] As a preferred embodiment, the longitudinal groove extends through the mounting housing, and an adjusting rod that passes laterally through the longitudinal groove is detachably threaded onto the upstream guide block.

[0009] As a preferred embodiment, the coating roller is rotatably mounted on the mounting housing via a rotating bracket. A glue storage box is also fixedly mounted on the mounting housing.

[0010] As a preferred embodiment, the sealing plate cooperates with the sealing frame, the sealing frame is provided with a sealing groove for the sealing plate to be inserted, and the sealing frame is fixedly installed at the longitudinal sliding groove of the mounting housing.

[0011] As a preferred embodiment, the metal sheet unwinding roller is also rotatably mounted on the mounting housing via a rotating bracket, and the metal sheet unwinds towards the downstream side of the coating roller.

[0012] After adopting the above technical solution, the effect of this utility model is as follows: The metal composite plate heating roller protection device includes a support base, on which a base plate is fixedly installed. A lower pressure roller group is rotatably installed on the base plate via an upper and lower mounting bracket. Above the lower pressure roller group are sequentially arranged a corresponding glue-applying roller, a composite roller group for longitudinally adjusting the composite position, and a traction protection roller for protecting the metal composite plate. The base plate is provided with a mounting housing supporting the glue-applying roller, the composite roller group, and the traction protection roller. A composite plate heating device is provided between the supporting glue-applying roller and the composite roller group. A metal plate unwinding roller is provided above the supporting glue-applying roller. First, the lower plate of the metal composite plate enters... The adhesive first contacts the gluing roller at the entrance of the mounting housing, while the lower pressure roller group provides support and auxiliary conveying. The gluing roller applies adhesive to the surface of the lower plate, which then continues to be conveyed. Simultaneously, the metal plate unwinding roller unwinds the upper plate, which contacts the lower plate. At the same time, the composite board heating device heats the adhesive, the upper plate, and the lower plate. Then, the composite roller group, which adjusts the longitudinal position, works with the lower pressure roller group to roll-press the composite board. Next, the composite board passes through the traction protection roller to check for excessive tension, ensuring accurate composite board bonding. Finally, it is conveyed to the next process. This device can roll-apply adhesive to the composite board while accurately bonding it, and it can also protect the composite board and ensure smooth and accurate traction.

[0013] Furthermore, the composite roller assembly includes an upstream composite roller that slides longitudinally on the mounting housing and a downstream composite roller assembly that is fixedly and rotatably mounted. The upstream composite roller is rotatably mounted on an upstream support frame, which is connected to an upstream lifting power device for driving lifting. Upstream guide blocks are fixedly mounted at both ends of the upstream support frame. The mounting housing is provided with a lifting groove for the upstream guide blocks to slide up and down and a longitudinal groove for sliding longitudinally. The downstream composite roller assembly includes multiple downstream composite rollers, which are rotatably mounted on a downstream support frame, which is connected to a downstream lifting power device for driving lifting. Downstream guide blocks are provided at both ends of the downstream support frame, and the mounting housing is provided with a lifting groove for the downstream guide blocks to slide up and down. The upstream composite roller first descends to cooperate with the lower pressure roller assembly. Then, the longitudinal position of the upstream composite roller is adjusted so that the upstream composite roller can perform early or late composite on the composite board, thereby changing the composite timing. Then, the downstream composite roller performs a second composite on the composite board that has been initially composited to ensure uniform roller pressure.

[0014] Furthermore, since the longitudinal groove penetrates the mounting housing, an adjusting rod that passes laterally through the longitudinal groove is detachably threaded onto the upstream guide block, and a sealing plate that closes the longitudinal groove is slidably mounted on the outer side of the mounting housing; by connecting the adjusting rod with the thread, the upstream composite roller can be pushed to slide along the longitudinal groove to a suitable position, and then the sealing plate can ensure internal sealing.

[0015] Furthermore, the composite board heating device includes a heating bracket that extends laterally and is installed in the mounting housing. A blowing device is longitudinally slidably mounted on the heating bracket via a longitudinal slide block. An electric heating wire is provided below the blowing device, and the blowing device is located between the glue coating roller and the upstream composite roller. This allows the lower board to be heated and composited in a timely manner after being coated with glue, thereby improving the composite effect.

[0016] Furthermore, since the traction protection roller is rotatably mounted on the traction support frame, the traction support frame is provided with a guide rod penetrating the bottom plate, the bottom plate is provided with a guide sleeve that cooperates with the guide rod, the bottom plate is provided with a support spring that is fitted on the guide rod to support the traction support frame, and an emergency switch to stop composite conveying is provided below the bottom plate. The traction support frame is provided with an emergency start rod that activates the emergency switch when the support spring is compressed. During the conveying of the metal composite plate, if the tension is too great, the metal composite plate will be straightened, thus pressing down on the traction protection roller. The support spring will be compressed, causing the emergency start rod to descend and touch the emergency switch, thereby stopping the conveying and protecting the composite plate.

[0017] Furthermore, since the glue-applying roller is rotatably mounted on the mounting housing via a rotating bracket, and a glue storage box is also fixedly mounted on the mounting housing, the glue storage box cooperates with the glue-applying roller for glue application, and the glue storage box is provided with a glue injection port; since the glue-applying roller also rotates and is conveyed along with the lower plate during the lower plate conveying, it can bring the glue in the glue storage box into contact with the lower plate during rotation, thereby applying the glue to the lower plate, saving extra glue application time, improving glue application efficiency, and allowing for quick replenishment of glue from the glue injection port.

[0018] Furthermore, since the sealing plate cooperates with the sealing frame, and the sealing frame is provided with a sealing groove for the sealing plate to be inserted, the sealing frame is fixedly installed at the longitudinal sliding groove of the mounting housing; this facilitates the disassembly of the sealing plate and ensures its effectiveness during heating and blowing.

[0019] Furthermore, since the metal plate unwinding roller is also rotatably mounted on the mounting housing via a rotating bracket, the metal plate unwinding roller unwinds towards the downstream side of the coating roller; ensuring that the lower plate is accurately coated with adhesive and then promptly laminated with the upper plate, resulting in accurate lamination.

[0027] The present invention will be further described in detail below through specific embodiments.

[0028] like Figures 1 to 5 As shown, a metal composite plate heating and rolling protection device includes a support base 1, a base plate 2 fixedly installed on the support base 1, a lower pressure roller group 3 rotatably installed on the base plate 2 via a lower mounting bracket 5, and a corresponding glue-applying roller 4, a composite roller group for longitudinally adjusting the composite position, and a traction protection roller 6 for protecting the metal composite plate arranged sequentially above the lower pressure roller group 3. The base plate 2 is provided with a mounting housing 7 that supports the glue-applying roller 4, the composite roller group, and the traction protection roller 6. A composite plate heating device is provided between the supporting glue-applying roller and the composite roller group, and a metal plate unwinding roller 8 is provided above the supporting glue-applying roller 4.

[0029] In this embodiment, the lower pressure roller group 3 is longitudinally arranged and rotatably mounted on the lower mounting frame 5. The mounting housing 7 is located upstream of the coating roller 4 and has an inlet 9 for the metal composite plate. The mounting housing 7 is located downstream of the traction protection roller 6 and has an outlet 10 for the metal composite plate.

[0030] like Figure 2 and Figure 3As shown, the composite roller assembly includes an upstream composite roller 11 that slides longitudinally on a mounting housing 7 and a downstream composite roller 12 assembly that is fixedly and rotatably mounted. The upstream composite roller 11 is rotatably mounted on an upstream support frame 13, and an upstream lifting power device for driving lifting is connected to the upstream support frame 13. Upstream guide blocks 14 are fixedly mounted at both ends of the upstream support frame 13 laterally. The mounting housing 7 is provided with a lifting groove 15 for the upstream guide blocks 14 to slide vertically and a longitudinal groove 16 for vertical sliding. The downstream composite roller 12 assembly includes multiple downstream composite rollers 12, which are rotatably mounted on a downstream support frame 17. A downstream lifting power device for driving lifting is connected to the downstream support frame 17, and downstream guide blocks 18 are provided at both ends of the downstream support frame 17 laterally. The mounting housing 7 is provided with downstream guide blocks 18 for vertical sliding. The lifting chute 15; the upstream lifting power device includes an upstream hydraulic cylinder 19, which is longitudinally slidably mounted on the mounting housing 7. First, the upstream hydraulic cylinder 19 drives the upstream support frame 13 to descend, thereby driving the upstream composite roller 11 to descend. Then, the upstream guide block 14 can slide along the longitudinal chute 16, and the upstream hydraulic cylinder 19 will also slide along it to ensure accurate roller pressing. At the same time, the roller pressing sequence position is changed, thereby changing the composite timing. There are two downstream composite rollers 12, which are arranged longitudinally in sequence. The downstream lifting power device includes a downstream hydraulic cylinder 20, which is also fixedly mounted on the mounting housing 7. It drives the downstream support frame 17 to slide along the lifting chute 15, thereby pressing the composite plate. Mounting ears 21 are provided on both the upstream hydraulic cylinder 19 and the downstream hydraulic cylinder 20. The mounting ears 21 are fixedly connected to the mounting housing 7 by screws.

[0031] like Figure 3 and Figure 5 As shown, the longitudinal groove 16 penetrates the mounting housing 7. An adjusting rod that passes laterally through the longitudinal groove 16 is detachably threaded onto the upstream guide block 14. A sealing plate that closes the longitudinal groove 16 is slidably mounted on the outer side of the mounting housing 7. The upstream guide block 14 can move along the longitudinal groove 16. By screwing the adjusting rod onto the upstream guide block, the upstream support frame 13 can be pushed to slide smoothly, improving convenience and facilitating disassembly. Subsequently, the sealing plate is used to close the groove, reducing heat loss during heating.

[0032] like Figure 2 and Figure 4As shown, the composite panel heating device includes a heating bracket 22 that extends laterally within the mounting housing 7. A blowing device 23 is longitudinally slidably mounted on the heating bracket 22 via a longitudinal slide block 25. An electric heating wire 24 is provided below the blowing device 23. The blowing device 23 is located between the coating roller 4 and the upstream composite roller 11. Two blowing devices 23 are laterally mounted on the heating bracket 22, which ensures that the metal composite panel pressed by the conveyor roller is heated evenly. The blowing device 23 can also cooperate with the upstream composite roller 11 through the longitudinal slide block 25 to improve the composite efficiency and effectively heat the composite panel within a certain longitudinal range. The blowing device 23 is an existing structure on the market, so it will not be described in detail in this article.

[0033] In this embodiment, the traction protection roller 6 is rotatably mounted on the traction support frame 26. The traction support frame 26 is provided with a guide rod 27 that penetrates the base plate 2. The base plate 2 is provided with a guide sleeve 28 that cooperates with the guide rod 27. The base plate 2 is provided with a support spring 29 that is fitted on the guide rod 27 to support the traction support frame 26. An emergency switch 30 for stopping composite conveying is provided below the base plate 2. The traction support frame 26 is provided with an emergency start rod 31 that activates the emergency switch 30 when the support spring 29 is compressed. The set height of the traction protection roller 6 is slightly higher than the set height of the lower pressure roller group 3. During the conveying of the metal composite plate, if the tension is too large, the metal composite plate will be straightened, thus pressing down the traction protection roller 6. The support spring 29 will be compressed, causing the emergency start rod 31 to descend and touch the emergency switch 30, thereby pausing the conveying and protecting the composite plate.

[0034] Furthermore, the glue-applying roller 4 is rotatably mounted on the mounting housing 7 via a rotating bracket 33. A glue storage box 32 is also fixedly mounted on the mounting housing 7. The glue storage box 32 cooperates with the glue-applying roller 4 for glue application. The glue storage box 32 is provided with a glue injection port 34. Since the glue-applying roller 4 also rotates and is conveyed along with the lower plate during the lower plate conveying process, it can bring the glue in the glue storage box 32 into contact with the lower plate during rotation, thereby applying the glue to the lower plate, saving extra glue application time, improving glue application efficiency, and allowing for quick replenishment of glue from the glue injection port 34.

[0035] In this embodiment, the sealing plate cooperates with the sealing frame 35, and the sealing frame 35 is provided with a sealing groove for the sealing plate to be inserted. The sealing frame 35 is fixedly installed at the longitudinal sliding groove 16 of the mounting housing 7; this facilitates the disassembly of the sealing plate and ensures its effectiveness during heating and blowing.

[0036] The metal plate unwinding roller 8 is also rotatably mounted on the mounting housing 7 via the rotating bracket 33. The metal plate unwinding roller 8 unwinds downstream of the glue coating roller 4 to ensure that the lower plate is accurately coated with glue and then promptly laminated with the upper plate, resulting in accurate lamination.

[0037] The working principle of this embodiment is as follows: First, the lower plate enters from the inlet 9. The lower pressure roller group 3 supports the lower plate while the glue application roller 4 rotates to apply glue to the upper surface of the lower plate. After the glue application is completed, the electric heating wire 24 heats up, the blowing device 23 starts blowing air, and the metal plate unwinding roller 8 starts unwinding the upper plate to contact the lower plate. The upstream hydraulic cylinder 19 drives the upstream unwinding roller to descend. Then, the longitudinal position of the upstream unwinding roller is adjusted to start the composite of the upper and lower plates. Then, the conveying continues. After the downstream unwinding roller descends, it presses the upper and lower plates. The conveying continues through the traction protection roller 6. When the tension is too large, the metal composite plate will be straightened, thus pressing down the traction protection roller 6. The support spring 29 will be compressed, thus causing the emergency start rod 31 to descend and touch the emergency switch 30 to stop the conveying. If the tension is normal, the support spring 29 will not be compressed, and the plate will be conveyed out from the outlet 10.

[0038] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications and alterations to the technical solution of the present utility model without departing from its design spirit shall fall within the protection scope defined by the claims of the present utility model.
