Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermal insulation board cutting, in particular to a low-foam debris cutting tool for wall thermal insulation boards. Background Art
[0002] Exterior wall insulation panels, also known as Horizon Building External Wall Decoration Integrated Panels, are primarily composed of a rigid panel sandwiched between foam panels (such as EPS, PU, or XPS). They combine insulation, energy conservation, waterproofing, and decorative features. They not only effectively reduce heat exchange between the wall and the exterior, lowering the building's energy consumption, but also help prevent rainwater intrusion and moisture. After factory production, insulation panels are further cut to the required size for ease of transportation and installation.
[0003] At present, insulation board manufacturers generally use traditional cutting devices to cut insulation boards, that is, a high-speed rotating cutting knife is used to cut the insulation board from one side to the other until it is cut off. The problem with this method is that during the cutting process, the foam debris cut off the foam board is thrown outward under the action of the cutting knife, which causes the cutting environment to be often filled with foam debris. In addition, the foam debris is light in weight, easy to transfer, and difficult to clean. This not only brings inconvenience to the processing of insulation boards, but also poses a safety hazard due to the foam and flammability. Utility Model Content
[0004] To address the above-mentioned issues, the present invention provides a low-foam debris cutting tool for wall insulation panels, which uses mechanical cutting and electric wire cutting to cut the insulation panels, significantly reducing the amount of foam debris generated during the cutting process. Specifically, the technical solution of the present invention is as follows.
[0005] A low-foam debris cutting tool for wall insulation panels comprises: a conveying mechanism, a lower support plate, an upper support plate, a reciprocating mechanism, a cutting mechanism, and a heating wire. The lower support plate is horizontally arranged at the output end of the conveying mechanism and the two are flush with each other. The lower support plate is divided into two parts spaced apart. The upper support plate is symmetrically arranged above the lower support plate and has the same structure. The reciprocating mechanism is arranged below the lower support plate, and the reciprocating mechanism and cutting mechanism are also arranged above the upper support plate, with the cutting mechanism fixed to the reciprocating mechanism. After the rotatable, vertically arranged cutting blade of the cutting mechanism below the lower support plate enters the gap between the two parts of the lower support plate under the drive of the reciprocating mechanism, the upper end of the cutting blade is located above the lower support plate. After the rotatable, vertically arranged cutting blade of the cutting mechanism above the upper support plate enters the gap between the two parts of the upper support plate under the drive of the reciprocating mechanism, the lower end of the cutting blade is located below the upper support plate. The heating wire is vertically arranged directly behind the cutting blade, and the upper and lower ends of the heating wire are respectively connected to the two groups of reciprocating motion mechanisms. The heating wire can generate heat after being energized, and then the high temperature generated is used to melt and cut the foam insulation layer in the insulation board to avoid the generation of foam debris.
[0006] Furthermore, the reciprocating mechanism includes a carrier plate, a first slider, a second slider, a lead screw, a slide rod, and a first drive motor. The carrier plate is horizontally disposed, and the cutting mechanism is fixed to the upper surface of the carrier plate. The first and second sliders are fixed to the lower surface of the carrier plate at intervals, and the lead screw and slide rod are parallel to the gap and cross the lower support plate. The first slider is threadedly connected to the lead screw, and the second slider is slidably connected to the slide rod. One end of the lead screw is connected to the first drive motor, and the other end of the lead screw is rotatably connected to the frame.
[0007] Furthermore, the cutting mechanism includes a cutting blade and a second drive motor, wherein the second drive motor is fixed on the upper surface of the carrier plate, the cutting blade is fixedly connected to the end of the motor shaft of the second drive motor, and the cutting blade is parallel to the gap.
[0008] Furthermore, the loading plate has an open slot, and the lower portion of the cutting blade passes through the open slot and is located below the open slot.
[0009] Furthermore, the lower end of the heating wire is rotatably connected to the carrier plate below the lower support plate through a first insulating joint, and the upper end of the heating wire is threadedly connected to the carrier plate above the upper support plate through a second insulating joint to adjust the tightness of the heating wire.
[0010] Furthermore, the first insulating joint is an inverted "T"-shaped circular tube, the upper end of which passes through the through hole on the carrier plate below the lower support plate and is fixedly connected to the lower end of the heating wire, and the lower end of the first insulating joint is limited on the lower surface of the carrier plate.
[0011] Furthermore, the second insulating joint is a vertically arranged bolt or screw, which is threadedly connected to a screw hole on the loading plate above the upper support plate.
[0012] Furthermore, the lower support plate and the upper support plate form a rectangular parallelepiped tubular structure with two ends open.
[0013] Compared with the prior art, the present invention has the following beneficial technical effects: The above-mentioned insulation board cutting tool of the present invention first uses two sets of upper and lower movable cutting mechanisms to cut the upper and lower hard panels of the insulation board, but will cut or only cut a small amount of the foam layer sandwiched between the hard panels. Instead, the foam layer is cut by the heating wire that moves synchronously with the cutting mechanism. At this time, the high temperature generated by the heating wire can melt and cut the foam layer. Since the hard panels have been cut at this time, it provides conditions for the heating wire to move forward. This method not only effectively reduces the harm caused by foam debris generated during the cutting process, but also has an edge sealing effect on the cut surface of the foam layer after melting and cutting, thereby improving the flatness of the cut surface of the foam layer.

Therefore, they cannot be understood as limiting the present invention.
[0022] It should be noted that the following detailed description is illustrative and intended to further illustrate the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which the present invention pertains. The present invention's low-foam chip cutting tool for wall insulation panels will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0023] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , an example of a low-foam chip cutting tool for wall insulation panels includes: a conveying mechanism 1, a lower support plate 2, an upper support plate 3, a reciprocating mechanism 4, a cutting mechanism 5, and a heating wire 6. Specifically, the conveying mechanism 1 is arranged horizontally, and the lower support plate 2 is arranged horizontally at the right output end of the conveying mechanism 1, and the two are aligned, so that the conveying mechanism 1 can be used to transport the insulation board 7 to be cut to the lower support plate 2 for cutting. The conveying mechanism 1 can be a conveyor belt, etc., and it can operate intermittently, advancing the insulation board 7 onto the support plate 2 by a set length after each cut.
[0024] The lower support plate 2 is divided into two parts, one on the left and the other on the right, spaced apart from each other, forming a gap 201 between the two parts of the lower support plate 2. The upper support plate 3 has the same structure as the lower support plate 2 and is symmetrically arranged above the lower support plate 2 with a gap therebetween, thereby forming a passage for the insulation plate 7 to pass through between the lower support plate 2 and the upper support plate 3.
[0025] The reciprocating mechanism 4 and the cutting mechanism 5 are each provided in two groups, with one group of the reciprocating mechanism 4 and the cutting mechanism 5 being provided below the lower support plate 2 and above the upper support plate 3. Specifically, the reciprocating mechanism 4 includes a loading plate 401, a first slider 402, a second slider 403, a lead screw 404, a slide rod 405, and a first drive motor 406.
[0026] Regarding the reciprocating mechanism 4 and cutting mechanism 5 disposed beneath the lower support plate 2, the carrier plate 401 is positioned horizontally, with the first and second sliders 402, 403 fixed to the lower surface of the carrier plate 401 at intervals. The lead screw 404 and slide bar 405 are parallel to the gap 201 and extend across the lower support plate 2. The first slider 402 is threadedly mounted on the lead screw 404, while the second slider 403 is slidably mounted on the slide bar 405. One end of the lead screw 404 is connected to the first drive motor 406, while the other end is rotatably connected to the frame 407.
[0027] The cutting mechanism 5 includes a cutting blade 501 and a second drive motor 502. The second drive motor 502 is fixed to the upper surface of the carrier plate 401. The carrier plate 401 has a strip-shaped opening 408, and the lower portion of the cutting blade 501 passes through the opening 408 and is located below it. The cutting blade 501 is fixedly connected to the end of the motor shaft of the second drive motor 502 and is parallel to the gap 201. When in use, the cutting mechanism 5 is located outside one end of the gap 201 of the lower support plate 2. The first drive motor 406 is activated to rotate the lead screw 404, thereby driving the carrier plate 401 carrying the cutting mechanism 5 along the lead screw 404 and the slide rod 405. The cutting blade 501 gradually enters from one end of the gap 201 to cut the hard panel on the lower surface of the insulation board 7 located on the lower support plate 2 until it is severed. Therefore, after the cutting blade 501 enters the gap 201, the upper end of the cutting blade 501 should extend slightly above the lower support plate 2 so that only the hard panel on the lower surface of the insulation board is cut, without cutting the foam insulation layer, or only a small amount of cutting is performed (e.g., the cutting depth of the foam insulation layer is 1 mm, 2 mm, etc.) to minimize the generation of foam debris. After cutting is completed, the reciprocating mechanism 4 drives the cutting mechanism 5 to return to its initial position. In addition, during cutting, the cutting blade 501 preferably rotates away from the heating wire 6 so that the generated debris is ejected away from the heating wire 6.
[0028] The reciprocating mechanism 4 and the cutting mechanism 5 arranged above the upper support plate 3 are the same as the reciprocating mechanism 4 and the cutting mechanism 5 below the lower support plate 2, and their main function is to cut the hard panel on the upper surface of the insulation board 7. Therefore, after the cutting blade 501 of the cutting mechanism 5 enters the gap 201, the lower end of the cutting blade 501 should extend a portion below the upper support plate 3. The two groups of the reciprocating mechanism 4 and the cutting mechanism 5 can be started at the same time to perform the cutting work. After the cutting is completed, the two groups of the reciprocating mechanism 4 and the cutting mechanism 5 return to the initial position, and the conveying mechanism 1 starts to work, conveying the insulation board 7 to the right to the set length, and at the same time pushing the cut insulation board 7 out from the right end of the upper support plate 3. The reciprocating mechanism 4 and the cutting mechanism 5 start to cut again.
[0029] The heating wire 6 is vertically arranged directly behind the cutting blade 501, and the upper and lower ends of the heating wire 6 are respectively connected to the loading plates 401 of the two groups of reciprocating mechanisms 4. The heating wire 6 can generate heat after being energized, and then use the generated high temperature to melt and cut the foam insulation layer in the insulation board 7, thereby avoiding the generation of foam debris. When in use, the heating wire 6 moves synchronously with the cutting mechanism 5. At this time, the high temperature generated by the heating wire 6 can melt and cut the foam layer, and since the hard panel has been cut at this time, conditions are provided for the movement of the heating wire 6. This embodiment not only effectively reduces the harm caused by the foam debris generated during the cutting process, but also the cut surface of the foam layer after melting and cutting has an edge sealing effect, thereby improving the flatness of the cut surface of the foam layer.
[0030] refer to Figure 4 In another embodiment, the lower end of the heating wire 6 is rotatably connected to the carrier plate 401 below the lower support plate 2 through a first insulating joint 601. Specifically, the first insulating joint 601 is an inverted "T"-shaped circular tube, the upper end of which passes through the through hole on the carrier plate 401 below the lower support plate 2 and is fixedly connected to the lower end of the heating wire 6, and the lower end of the first insulating joint 601 is limited on the lower surface of the carrier plate 401. The second insulating joint 602 at the upper end of the heating wire 6 is threadedly connected to the carrier plate 401 above the upper support plate 3. Specifically, the second insulating joint 602 is a vertically arranged bolt or screw, which is threadedly connected to the screw hole on the carrier plate 401 above the upper support plate 3. The tightness of the heating wire 6 can be adjusted by rotating the second insulating joint 602 so that the heating wire 6 is in a tensioned state, which is convenient for cutting. The material of the first insulating joint 601 and the second insulating joint 602 can be ceramic, etc.
[0031] refer to Figure 5In another embodiment, the lower support plate 2 and upper support plate 3 form a rectangular tubular structure with open ends. This allows the insulation board 7 to be positioned within the structure, preventing it from moving under the thrust of the cutting blade 501 and affecting cutting accuracy. Furthermore, the end of the tubular structure near the right end / output end of the conveying mechanism 1 is formed into an outwardly flared bell mouth to facilitate the entry of the insulation board 7.
[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
