Description

Technical Field

[0001] This utility model relates to the field of insulation board processing technology, specifically to an end-folding device for insulation boards. Background Technology

[0002] Insulation boards are energy-saving building materials composed of outer steel plates, inner steel plates, and core insulation materials. They are widely used in building exterior walls, industrial plant enclosure systems, cold chain logistics facilities, clean rooms, and ship cold storage.

[0003] End-folding of insulation boards refers to a forming process in which the inner steel plate and insulation core material are partially removed at the cut end of the board section, leaving only the extended portion of the outer steel plate, which is then bent inward at a 90-degree angle to tightly fit against the side of the core material. The core purpose of this process is to conceal the edge of the outer steel plate within the board, preventing rust caused by rainwater erosion, while also meeting the requirements for a smooth building appearance and a sealed connection during installation. It is a key technical step in ensuring the durability and aesthetics of the building envelope system.

[0004] Current end-edge bending processes mainly rely on manual hammering or simple mechanical bending. While mechanical methods can complete the initial bending, the bending angle can usually only reach about 80 degrees, which cannot completely fit the side of the insulation core material. Subsequently, construction workers need to use tools such as wooden mallets to hammer and shape it, which is not only inefficient and labor-intensive, but also difficult to control the bending force evenly, which can easily cause uneven end faces, damage to steel plates, or angle deviations, resulting in poor product quality stability. Utility Model Content

The trimming mechanism is used to press the folded edge toward the end of the heat insulation board with a pressing roller, and a translation mechanism whose output end is vertically rotatably connected to the pressing roller and used to drive the pressing roller to move back and forth.

[0009] As a further technical solution of this utility model, the bending mechanism includes a bending knife, a lifting hydraulic cylinder mounted on the conveyor frame for driving the bending knife to move up and down, a bending arm horizontally rotatably connected to the conveyor frame and used to cooperate with the bending knife to bend the edge of the insulation board, and a bending cylinder for the bending arm to swing back and forth.

[0010] As a further technical solution of this utility model, the lower right side of the bending blade is inclined from top to bottom and to the left.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 5 As shown in the figure, an end-folding device for insulation boards in this embodiment of the present invention includes a conveyor frame 100 that drives the insulation board to move horizontally left and right, a bending mechanism 200 installed on the conveyor frame 100 for bending the lower edge of the insulation board, and a trimming mechanism 300 spaced to the right of the bending mechanism 200. In practice, the conveyor frame 100 can be powered, such as a conveyor belt driven by a motor in conjunction with chain drive, belt drive, or gear drive, to achieve automatic conveying of the insulation board. Alternatively, it can be unpowered, such as having multiple rollers spaced left and right, which, in conjunction with the operator's pushing, achieve horizontal conveying. In this invention, the outer side of the insulation board faces downwards, i.e., the outer steel plate to be bent faces downwards, and it moves horizontally or remains on the conveyor frame 100 under the action of the conveyor frame 100. The bending mechanism 200 may be a bending blade 210, a lifting assembly that drives the bending blade 210 to move up and down, and a bending seat that cooperates with the bending blade 210. When the bending blade 210 moves down to contact the position where the outer steel plate needs to be bent and cooperates with the bending seat, the lower edge of the insulation bag is bent to more than 80 degrees.

[0029] The trimming mechanism 300 is used to press the folded edge against the end of the insulation board using a pressing roller 310, and a translation mechanism 320 whose output end is vertically rotatably connected to the pressing roller 310 and used to drive the pressing roller 310 to move back and forth. That is, the rotation axis of the pressing roller 310 is perpendicular to the horizontal. In practice, the translation mechanism 320 can be a linear drive device such as a cylinder, hydraulic cylinder, or electric push rod, so as to drive the pressing roller 310 to move back and forth until it contacts the bent edge and presses the edge against the end of the insulation board, so that the edge is tightly close to the end.

[0030] The specific working process of the trimming mechanism 300 of this utility model is as follows: Before operation, the pressing roller 310 is initially positioned in front of or behind the end of the insulation board. When pressing is required, the insulation board is first fixed relative to the conveyor frame 100 by external pressing components and manual operation. Then, the translation mechanism 320 drives the pressing roller 310 to move backward or forward, so that the pressing roller 310 contacts the folded edge and presses it precisely to the end of the insulation board. The pressing roller 310 moves and rolls while continuously pressing the folded edge. If the fit is still insufficient after a single pressing, the translation mechanism 320 can continue to drive the pressing roller 310 to apply pressure back and forth multiple times until the folded edge is completely fitted to the end of the insulation board, achieving the expected trimming effect.

[0031] The end-folding device of the insulation board in this utility model, through the cooperation of the conveyor frame 100, the bending mechanism 200 and the trimming mechanism 300, can make the bending fit with the insulation section, greatly reducing the intensity of manual intervention in the trimming work, reducing uneven end face, steel plate damage and angle deviation, and improving the stability of product quality.

[0032] It should be noted that the insulation board end folding device of this utility model preferably includes a clamping mechanism 400 mounted on the conveyor frame 100 for clamping the insulation board with the conveyor frame 100. The clamping mechanism 400 is spaced apart to the left of the bending mechanism 200. In fact, the clamping mechanism 400 can be a lifting pressure plate driven by a cylinder or hydraulic cylinder. The cylinder drives the pressure plate to move up and down, so that the pressure plate and the surface of the conveyor frame 100 form a clamping force on the insulation board, thereby fixing the insulation board in the processing position, avoiding the displacement of the folding position caused by the movement of the board during the bending process, and improving the processing stability and product quality.

[0033] Specifically, the clamping mechanism 400 preferably includes a clamping beam 410 extending forward and backward, and two lifting cylinders 420 correspondingly installed on the front and rear sides of the conveyor frame 100 to drive the clamping beam 410 to move up and down. The two lifting cylinders 420 are correspondingly installed on the front and rear sides of the conveyor frame 100 and synchronously drive the clamping beam 410 to move up and down. Since the cylinders are arranged outside the conveying plane, they will not interfere with the normal conveying of the insulation board. In addition, the synchronous action of the two cylinders can ensure that the clamping beam 410 is subjected to balanced force at both ends and moves up and down in parallel, thereby applying a uniform and stable clamping force to the front and rear areas of the insulation board and preventing the board from shifting due to tilting of the clamping beam 410 or insufficient local clamping.

[0034] Specifically, the bending mechanism 200 preferably includes a bending blade 210, a lifting hydraulic cylinder 220 mounted on the conveyor frame 100 for driving the bending blade 210 to move up and down, a bending arm 230 horizontally rotatably connected to the conveyor frame 100 for cooperating with the bending blade 210 to bend the edge of the insulation board, and a bending cylinder 240 for the bending arm 230 to swing back and forth. In actual operation, the lifting hydraulic cylinder 220 drives the bending blade 210 downwards, pressing and positioning the extension of the outer steel plate to be bent; at this time, the bending arm 230 is in state one. Subsequently, the bending cylinder 240 pushes the bending arm 230 to swing inwards. During the swinging process, the bending arm 230 cooperates with the bending blade 210 to push the extension of the outer steel plate inwards to a predetermined angle (usually more than 80 degrees); at this time, the bending arm 230 is in state two. After bending is completed, the bending cylinder 240 drives the bending arm 230 to reset, and the lifting hydraulic cylinder 220 drives the bending blade 210 upwards to return to its original position, completing a single bending cycle. Through the coordinated action of the lifting hydraulic cylinder 220 and the bending cylinder 240, the mechanized operation of bending the end of the insulation board is realized.

[0035] More specifically, the lower right side of the bending blade 210 is preferably inclined from top to bottom and to the left. The inclined surface significantly reduces the initial contact area between the bending blade 210 and the extension of the outer steel plate when it moves downward, thereby reducing surface friction resistance, avoiding large-area rigid compression, and making the bending action smoother.

[0036] It should be noted that the trimming mechanism 300 preferably includes a slide 330 slidably connected to the conveyor frame 100 and a trimming cylinder 340 mounted on the slide 330 for driving the pressing roller 310 to move left and right. The pressing roller 310 is vertically rotatably connected to the output end of the trimming cylinder 340. The translation mechanism 320 is used to drive the slide 330 to move back and forth. During the trimming operation, the translation mechanism 320 drives the slide 330 to move back and forth, causing the pressing roller 310 to perform continuous pressing operations along the folded edge length direction. During this process, the trimming cylinder 340 pushes the pressing roller 310 to press towards the end of the insulation board, thereby controlling whether the pressing roller 310 presses against the end of the insulation board and rotating the working state of the pressing roller 310 according to actual needs.

[0037] Specifically, the left side of the slide 330 preferably has a positioning block 331 for abutting against the end of the insulation board. The positioning process is as follows: when the folded edge needs to be trimmed, the translation mechanism 320 first moves the slide 330 to the middle of the conveyor frame 100, so that the positioning block 331 abuts against the end of the insulation board to form a positioning reference, ensuring that the starting position of the pressing roller 310 is aligned with the root of the folded edge; then the translation mechanism 320 drives the slide 330 to move forward or backward continuously, so that the pressing roller 310 rolls and applies pressure along the length of the folded edge. During this process, the trimming cylinder 340 drives the pressing roller 310 to press against the end of the insulation board until the trimming operation of the entire folded edge is completed. By controlling the trimming starting point through the end hard limit method, the empty stroke or pressure deviation of the pressing roller 310 is effectively avoided, significantly improving the consistency of the folded edge angle and the forming accuracy, which is suitable for continuous automated trimming of long-sized boards.

[0038] Furthermore, the lower side of the positioning block 331 is preferably located between the upper and lower sides of the insulation board. When the positioning block 331 is located at the middle working position of the conveyor frame 100, its bottom can block the main body of the insulation board from the inside to prevent the insulation board from continuing to move to the right. The distance between the lower side of the preferred positioning block 331 and the lower side of the insulation board is greater than the extension length of the folded edge. This distance setting ensures that the positioning block 331 only contacts the end face of the main body of the insulation board and does not interfere with the already bent folded edge, thereby avoiding affecting the subsequent trimming operation of the folded edge by the pressing roller 310.

[0039] Furthermore, the conveyor frame 100 is preferably horizontally rotatably connected to a support roller 110 between the working positions of the slide 330 and the bending mechanism 200. The support roller 110 is located below the insulation board on the lower side near the folded edge, and is used to provide auxiliary support for the board during the finishing process. Through the rolling support of the support roller 110, the insulation board is prevented from being affected by cantilever deformation, thus avoiding affecting the folding angle accuracy, thereby providing a more stable rigid foundation for pressing and finishing, and improving the reliability and consistency of the finishing effect.
