Description

Technical Field

[0001] This invention relates to the technical field of PIR duct cutting, and more particularly to a multifunctional PIR duct processing device and its application method. Background Technology

[0002] PIR composite ducts, short for polyisocyanurate PIR insulated composite ducts, are a type of composite material duct. PIR ducts utilize a sandwich panel structure, with a core layer of PIR polymer monomers (a type of polyurethane-modified rigid polyisocyanurate foam) and top and bottom metal sheets, providing fire resistance or insulation. Compared to other types of ducts, PIR composite ducts offer advantages such as flame retardancy, lightweight and aesthetics, energy efficiency, anti-mildew and antibacterial properties, heat insulation, moisture insulation, sound insulation, quick and easy installation, stable physical properties, high insulation, and high strength. They exhibit significant advantages in material performance, manufacturing, installation, and economic benefits. The layout, cutting, and grooving of the panels is a crucial step in the PIR composite duct construction process; the quality of this work directly impacts subsequent air leakage testing, particularly affecting energy efficiency.

[0003] When standard PIR ducts leave the factory, they are generally processed according to the specific installation dimensions on site, as follows: First, the rectangular PIR duct sheet is cut, usually manually. Generally, the operators need to stand opposite each other, each measuring the length of the PIR duct sheet. One operator holds the blade and makes the cut, while the other operator stands opposite to observe whether the cutting lines are aligned with the markings. At the same time, a heavy object is needed to press down on the PIR duct sheet to prevent displacement during the cutting process, which could lead to cutting errors. After the cutting is completed, a worker needs to apply glue to the cut surface and fold it.

[0004] In summary, existing PIR duct sheet cutting methods have the following disadvantages:

[0005] (1) The cutting process requires multiple operators, which is time-consuming and labor-intensive. After a day of hard work, the PIR ducts that can be cut and processed are limited.

[0006] (2) Each board needs to be measured multiple times during the cutting process. Due to the long processing time, the operator may not be able to concentrate, resulting in cutting errors. In addition, the board is easy to move and slide on the simple cutting workbench, which can easily lead to crooked bevels that do not meet the assembly requirements, resulting in a large number of scraps.

[0007] (3) Applying glue and folding requires an additional worker, which increases labor costs and is inefficient.

[0008] (4) It requires manual cutting by operators. The V-shaped push knife is used to measure and mark the cut. Generally, a section of air duct needs to be measured and marked multiple times. The middle bevel needs to be marked twice and cut twice to form a V-shaped bevel. The process is complicated.

[0009] (5) Each time the next piece of board is replaced, the layout and measurement need to be repeated, which is inefficient. Summary of the Invention

[0010] The purpose of this invention is to provide a multi-functional PIR duct processing device and its application method that can save labor, improve processing efficiency, shorten processing time, and facilitate transportation and storage.

[0011] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] A multi-functional processing device for PIR ductwork is disclosed for cutting rectangular PIR ductwork sheets at folded positions. The device includes an operating platform, a drive mechanism, a limiting mechanism, and an operating mechanism. The operating platform is a rectangular frame with support legs connected to the bottom corners of the frame to provide a cutting platform. The drive mechanism is positioned between the two short sides of the frame and parallel to the two long sides, driving the operating mechanism to achieve displacement. Two sets of limiting mechanisms are adjustable and located on both sides of the operating mechanism to control the PIR ductwork sheet. The short side is used for pressing and limiting; the operating mechanism is located between the two short sides of the frame and its displacement is controlled by the driving mechanism for cutting the PIR duct panel; the operating mechanism includes a cutting mechanism, which includes a support frame, a support plate, a first slide plate, a first slide, and a cutting head; the support plate is displaced on the driving mechanism, and both ends of the support plate are connected to the first slide plate through the support frame. The first slide plate is parallel to the short side of the frame, and the first slide is provided on the axis of the first slide plate. The cutting head is slidably mounted on the first slide; the cutting head includes a handle and a blade;

[0013] The operating mechanism also includes an adhesive application mechanism, which is adjustablely disposed on one side of the cutting mechanism and parallel to the cutting mechanism, for applying adhesive to the cut surfaces of the PIR duct sheet.

[0014] The glue application mechanism includes a second sliding plate, a second sliding groove, and a glue application head. The second sliding plate is connected to the outside of the support frame via an adjustable extension frame. The second sliding groove is provided on the axis of the second sliding plate, and the glue application head is slidably mounted on the second sliding groove. The glue application head is equipped with a displacement sensor and a distance sensor, and both the displacement sensor, the distance sensor, and the glue application head are connected to the control system. The glue application head is connected to the handle via a connecting rod.

[0015] The detection threshold of the distance sensor on the glue application mechanism is preset, and this threshold should be consistent with the cutting depth that the blade can cut.

[0016] Preferably, the cutting head further includes a handle slider seat, a connecting threaded rod, a blade mounting block, and a blade mounting block base; the connecting threaded rod is provided on the axis at the bottom of the handle, and the handle is mounted on the slide groove through the handle slider seat; the blade mounting block is vertically arranged, and its bottom is connected to the blade mounting block base, which is connected to the blade by fasteners; the top of the blade mounting block is provided with an internal thread that matches the external thread of the connecting threaded rod; the connecting threaded rod passes through the lower part of the slide groove and is fastened to the blade mounting block by threads.

[0017] Preferably, each set of limiting mechanisms includes two adjusting guide rails, a shelf plate, and two sets of pressure blocks; the two adjusting guide rails are symmetrically arranged on the long side of the frame with the short side as the axis, and the two sets of pressure blocks are symmetrically and movably arranged on the two adjusting guide rails through threaded adjusting rods. Each set of pressure blocks has a gripping head at one end opposite to the other. The shelf plate has at least two stops on its outer side away from the cutting mechanism, and claw hooks are provided at both ends of the shelf plate. The shelf plate is engaged with the two sets of gripping heads through the claw hooks.

[0018] Preferably, the support plate of the cutting mechanism is provided with an adjusting block mechanism at one end. The adjusting block mechanism includes an adjusting block, an adjusting groove, and a fixing knob. The adjusting groove is located at one end of the support plate, and the fixing knob is threaded through the adjusting block and movably mounted on the adjusting groove, for pressing the long side of the PIR duct sheet material of different widths.

[0019] Preferably, a scale is provided on each long side of the frame; the two sections of the support plate on the cutting mechanism are symmetrically provided with triangular pointing blocks, the vertices of the pointing blocks are aligned with the scale, and are used to mark the cutting position of the PIR duct plate.

[0020] Preferably, the bottom corners of the frame of the operating platform and the supporting legs are folded together by a folding mechanism.

[0021] Preferably, the folding mechanism includes a pneumatic telescopic rod, a telescopic rod slide rail, and a connecting shaft; the support leg is connected to the operating platform via the connecting shaft; the telescopic rod slide rail is vertically mounted on the support leg, and the operating platform adjacent to the support leg is connected to the telescopic rod slide rail via a pneumatic telescopic rod.

[0022] This invention also provides an application method based on a PIR duct multifunctional processing device, comprising the following steps:

[0023] Step S0: Preparation - The operator installs the operating platform level and the cutting mechanism level on the long side of the operating platform and the cutting mechanism respectively, and observes and adjusts them in real time before operation;

[0024] The detection threshold of the distance sensor on the glue application mechanism is preset, and this threshold should be consistent with the cutting depth that the blade can cut.

[0025] The blade is a V-shaped blade, which is installed to the bottom of the blade mounting block base using fasteners;

[0026] Step S1: Pressing and limiting - The PIR duct sheet to be cut is laid flat on the operating platform, and the middle section of the PIR duct sheet is supported by the support plate. The short side of the PIR duct sheet to be cut is pressed and limited by the limiting mechanisms on both sides of the operating mechanism.

[0027] The long side of the PIR duct sheet to be cut is limited by the adjusting stop mechanism on the support plate of the cutting mechanism.

[0028] The operator marks the cutting position on the PIR duct plate to be cut according to the scale on the long side of the operating platform;

[0029] Step S2: Adjust the operating mechanism—The operator adjusts the distance between the glue application mechanism and the cutting mechanism in the operating mechanism by adjusting the extension frame according to the required cutting size;

[0030] In practical applications, the glue application mechanism is located above the cutting station of the cutting mechanism and is used to apply glue to the V-shaped groove that has been cut.

[0031] Step S3: Cutting and gluing - The operator holds the handle of the cutting mechanism and moves it linearly in the slide groove. The connecting threaded rod at the bottom of the handle drives the V-shaped blade connected to the base of the blade mounting block to cut the PIR duct plate to be cut through the blade mounting block connected to it.

[0032] The operator removes the waste material that has been cut off from the PIR duct plate; at the same time, the driving mechanism moves the operating mechanism to the next cutting position, which is the cutting position marked in step S1. When the glue application mechanism detects that the depth of the V-groove cut by the V-blade on the PIR duct plate meets the preset threshold through the distance sensor, it feeds back to the control system, and the control system controls the displacement sensor of the glue application head to start.

[0033] When the operator pushes the handle of the cutting mechanism again to move linearly in the slide, the PIR duct plate to be cut is cut again; the operator removes the waste material that has been cut off from the PIR duct plate again.

[0034] Meanwhile, since the handle is connected to the glue applicator head of the glue applicator through the connecting rod, and the displacement sensor of the glue applicator head is already activated, when the handle drives the glue applicator head to slide in a straight line in the second slide, the displacement sensor will send a signal to the control system. The control system will control the glue applicator head to dispense glue, and the glue will fall precisely into the pre-cut V-shaped groove.

[0035] Step S4: Repeat step S3 to cut and apply adhesive until the required folding position of the PIR duct plate is cut;

[0036] Step S5: Material collection - The operator releases the pressure on the long and short sides of the PIR duct plate by using the limiting mechanism and the adjusting block mechanism. After rotating the two sets of pressure blocks by ° through the threaded adjusting rods on both sides of the frame, the support plate that is clamped between the two sets of pressure blocks by the gripping head is removed, and then the cut PIR duct plate is removed.

[0037] Step S6: Folding and Assembly—The operator folds the PIR duct sheet based on the glued V-groove and manually applies glue to the last edge of the cut PIR duct sheet, thereby folding and bonding the two ends of the PIR duct sheet to form a rectangular cavity PIR duct.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] (1) The present invention provides a cutting head that can slide linearly in a chute and a mounting block that is threaded to achieve a detachable connection, thereby adapting to different cutting heads.

[0040] (2) By setting a limiting mechanism and an adjusting block mechanism, the long side and short side of the rectangular PIR duct plate can be limited respectively, so that it is not easy to shift during the cutting and gluing process, which facilitates the operation of the operator and improves the yield of the cut product.

[0041] (3) By setting an adjustable glue-applying mechanism on one side of the cutting mechanism, the glue-applying head of the glue-applying mechanism is driven by the handle of the cutting mechanism through the connecting rod. At the same time as completing one cut, glue can be dripped into the previous cutting station, thereby reducing labor costs, processing time and improving processing efficiency.

[0042] (4) The present invention sets a position sensor and a distance sensor on the glue coating mechanism respectively. The distance sensor feeds back to the control system to start the position sensor, and the position sensor starts the glue coating head to drip glue, thereby realizing automated glue dispensing and improving production efficiency.

[0043] (5) The present invention sets the glue application mechanism and the cutting mechanism to be adjustable, so that the distance between the glue application mechanism and the cutting mechanism can be adjusted as needed, thereby adapting to the processing of more types of PIR duct plates.

[0044] (6) By setting an infrared alignment device on the cutting mechanism, the present invention can observe whether the cutting head on the cutting mechanism is deviated, thereby improving the yield of the cut product.

[0045] (7) The present invention can observe whether the position of the operating platform and the cutting mechanism is tilted by using the operating platform level and the cutting mechanism level, thereby improving the cutting yield.

[0046] (8) The present invention enables the operating platform and support legs to be folded through a folding mechanism, which facilitates transportation and storage, and at the same time expands its applicable sites and scope.

[0047] In summary, this invention, based on automated gluing, can complete both cutting and gluing functions in a single sliding motion, saving labor, improving processing efficiency, and shortening the processing time. Furthermore, the foldable design facilitates transportation and storage, expanding its applicability to various locations and applications. Attached Figure Description

[0060] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0061] Figure 1 A three-dimensional structural diagram of a multi-functional PIR duct processing device provided in this embodiment. Figure 1 .

[0062] Figure 6This is a schematic diagram of the folding mechanism in a multi-functional PIR duct processing device provided in this embodiment.

[0063] like Figure 1 As shown, a multi-functional PIR duct processing device 100 disclosed in this invention is used to cut the folded position of a rectangular PIR duct sheet, including an operating platform 110, a driving mechanism 130, a limiting mechanism 140 and an operating mechanism 150.

[0064] The operating platform 110 uses a rectangular frame to provide a cutting platform. For example... Figure 6 As shown, the bottom corners of the rectangular frame are connected to the support legs 120 via folding mechanisms 180 to achieve a folding connection. The folding mechanism 180 includes a pneumatic telescopic rod 181, a telescopic rod slide rail 182, and a connecting shaft 183; the support legs 120 are connected to the operating platform 110 via the connecting shaft 183; the telescopic rod slide rail 182 is vertically mounted on the support legs 120, and the operating platform 110 adjacent to the support legs 120 is connected to the telescopic rod slide rail 182 via the pneumatic telescopic rod 181.

[0065] The telescopic rod of the pneumatic telescopic rod 181 slides simultaneously in the telescopic rod guide rail 182 of its corresponding support leg 120, thereby achieving the effect of folding the support leg 120.

[0066] Furthermore, in this embodiment, the adjacent support legs 120 on the short side of the frame of the operating platform 110 are connected by cross connectors 190, which can achieve the effect of being stably placed on the ground.

[0067] Figure 2 A three-dimensional structural diagram of a multi-functional PIR duct processing device provided in this embodiment. Figure 2 .

[0068] like Figure 1 and 2 As shown, the drive mechanism 130 is located between the two short sides of the frame and parallel to the two long sides of the frame. The drive mechanism 130 drives the connected operating mechanism 150 to achieve displacement.

[0069] like Figure 2 As shown, in this embodiment, the drive mechanism 130 adopts a threaded screw, including a threaded screw 131 and a screw nut block 132. The two ends of the threaded screw 131 are respectively mounted on the central axis of the two short sides of the operating platform 110 through the mounting bracket 132. One end of the threaded screw 131 is connected to the output end of the drive motor 133, and a screw nut sleeve 134 is sleeved on the threaded screw 131. The drive motor 133 drives the threaded screw 131 to rotate, thereby causing the screw nut sleeve 134 to slide along the thread on the threaded screw.

[0070] Figure 3This is a schematic diagram of the limiting mechanism in a PIR duct multifunctional processing device provided in this embodiment.

[0071] like Figure 3 As shown, the limiting mechanism 140 consists of two sets, which are adjustable and set on both sides of the operating mechanism 150 to press and limit the short side of the PIR duct plate.

[0072] Each set of limiting mechanisms 140 includes two adjusting guide rails 141, a shelf 142, and two sets of pressure blocks 143. The two adjusting guide rails 141 are symmetrically arranged on the long side of the frame with the short side as the axis. The two sets of pressure blocks 143 are symmetrically and movably arranged on the two adjusting guide rails 141 through threaded adjusting rods 144. Each set of pressure blocks 143 has a gripping head 145 at one end opposite to the other. The shelf 142 has at least two stops 146 on the outer side away from the cutting mechanism 151. Both ends of the shelf 142 are provided with claw hooks. The shelf 142 is engaged with the two sets of gripping heads 145 through the claw hooks.

[0073] In practical applications, the shelf 142 can be engaged with the pressure block through various structures to achieve the functions of pressing and limiting (since there are many ways to do this in the existing technology, they will not be described in detail here).

[0076] like Figure 4 and Figure 5 As shown, the operating mechanism 150 is located between the two short sides of the frame and its displacement is controlled by the drive mechanism 130. It is used to cut PIR duct panels and apply adhesive.

[0080] Figure 10A schematic diagram of the cutting head structure in a PIR duct multi-functional processing device provided in this embodiment. Figure 2 .

[0081] like Figures 7 to 10 As shown, the operating mechanism 150 includes a cutting mechanism 151 and an adhesive applicator 154. The cutting mechanism 151 is parallel to the short side of the frame of the operating platform 110. The adhesive applicator 154 is adjustablely arranged on one side of the cutting mechanism 151 and is parallel to the cutting mechanism 151.

[0082] The cutting mechanism 151 includes a support frame 153, a support plate 155, a sliding groove plate 1511, a sliding groove 1512, and a cutting head 1513. The bottom of the support plate 155 is displaced and sleeved on the threaded screw 131 via a screw nut sleeve 134, and slides along the screw nut sleeve 134 as it slides on the threaded screw 131. The two ends of the support plate 155 are connected to the sliding groove plate 1511 via the support frame 153. The sliding groove plate 1511 is parallel to the short side of the frame. The sliding groove 1512 is provided on the axis of the sliding groove plate 1511, and the cutting head 1513 is slidably mounted on the sliding groove 1512.

[0083] The cutting head 1513 includes a handle 1519, a handle slider seat 1514, a connecting threaded rod 1515, a blade mounting block 1516, a blade mounting block base 1517, and a blade. The connecting threaded rod 1515 is located on the axis at the bottom of the handle 1519, and the handle 1519 is mounted on a slide groove 1512 via the handle slider seat 1514. The blade mounting block 1516 is vertically positioned, and its bottom is connected to the blade mounting block base 1517, which connects to the blade via fasteners. The top of the blade mounting block 1516 has an internal thread that matches the external thread of the connecting threaded rod 1515. The connecting threaded rod 1515 passes through the lower part of the slide groove 1512 and is threadedly fastened to the blade mounting block 1516. This threaded connection also facilitates the replacement of different blade mounting blocks or blades at the bottom. In this embodiment, the blade is a V-shaped blade 1518. In practical applications, different single or double blades can be replaced according to cutting needs, thereby extending the service life of the cutting head and facilitating maintenance and adapting to different cutting types.

[0084] Furthermore, the support plate 155 of the cutting mechanism 151 of the present invention is provided with an adjusting block mechanism 158 at one end. The adjusting block mechanism 158 includes an adjusting block 1581, an adjusting groove 1582 and a fixing knob 1583. The adjusting groove 1582 is provided at one end of the support plate 155, and the fixing knob 1583 is threaded through the adjusting block 1581 and movably provided on the adjusting groove 1582, for pressing the long side of PIR duct sheet material of different widths.

[0085] Furthermore, the long side of the frame of the operating platform 110 of the present invention is provided with a scale 170; the two sections of the support plate 155 on the cutting mechanism 151 are symmetrically provided with triangular pointing blocks 156, the apex of the pointing block 156 is connected to the scale 170, and is used to mark the cutting position of the PIR duct plate.

[0086] The adhesive application mechanism 154 is used to apply adhesive to the cut surfaces of PIR duct panels. It includes a second sliding plate 1541, a second sliding groove 1542, and an adhesive application head 1543. The second sliding plate 1541 is connected to the outside of the support frame 153 via an adjustable extension frame 1531. The second sliding groove 1542 is located on the axis of the second sliding plate 1541, and the adhesive application head 1543 slides on the second sliding groove 1542. The adhesive application head 1543 is equipped with a displacement sensor and a distance sensor. Both the displacement sensor, the distance sensor, and the adhesive application head 1543 are connected to a control system. The technology of the control system controlling the adhesive application head 1543 to apply adhesive is existing technology. All applicable structures in the prior art can be applied here, which is not the technical solution of this invention, and therefore will not be described in detail here. A detection threshold for the distance sensor on the adhesive application mechanism 154 is preset, and this threshold should be consistent with the cutting depth that the blade can cut.

[0087] The glue applicator 1543 is connected to the handle 1519 via a connecting rod. This connecting rod allows the handle 1519 to move the glue applicator 1543.

[0088] The present invention relates to an application method for a PIR duct multifunctional processing device, comprising the following steps:

[0089] Step S0: Preparation - The operator installs the operating platform level 160 and the cutting mechanism level 152 on the long side of the operating platform 110 and the cutting mechanism 151 respectively, and observes and adjusts them in real time before operation;

[0090] The V-shaped blade 1518 is mounted to the bottom of the blade mounting block base 1517 using fasteners;

[0091] Step S1: Pressing and limiting - The PIR duct sheet to be cut is laid flat on the operating platform 110, and the middle section of the PIR duct sheet is supported by the support plate 155. The short side of the PIR duct sheet to be cut is pressed and limited by the limiting mechanism 140 on both sides of the operating mechanism 150.

[0092] The adjusting stop mechanism 158 on the support plate 155 of the cutting mechanism 151 limits one long side of the PIR duct plate to be cut.

[0093] The operator marks the cutting position on the PIR duct plate to be cut according to the scale 170 on the long side of the operating platform 110.

[0094] Step S2: Adjust the operating mechanism—The operator adjusts the distance between the glue application mechanism 154 and the cutting mechanism 151 in the operating mechanism 150 by adjusting the extension frame 1531 according to the required cutting size;

[0095] In practical applications, the glue application mechanism 154 is positioned above the cutting station of the cutting mechanism 151 and is used to apply glue to the V-shaped groove that has been cut.

[0096] Step S3: Cutting and Glue Application—The operator holds and pushes the handle 1519 of the cutting mechanism 151, moving it linearly in the slide groove 1512. The connecting threaded rod 1515 at the bottom of the handle 1519 drives the V-shaped blade 1518 connected to the blade mounting block base 1517 to cut the PIR duct plate to be cut through the blade mounting block 1516 connected to it. The operator removes the waste material cut off from the PIR duct plate. At the same time, the driving mechanism 130 drives the operating mechanism 150 to move to the next cutting position, which is the cutting position marked in step S1. The glue application mechanism 154 detects that the depth of the V-shaped groove cut by the V-shaped blade on the PIR duct plate meets the preset threshold through the distance sensor, and feeds back to the control system. The control system controls the displacement sensor of the glue application head 1543 to start.

[0097] When the operator holds the handle 1519 of the cutting mechanism 151 and pushes it to move linearly in the slide 1512, the PIR duct plate to be cut is cut again at the marked cutting position.

[0098] Meanwhile, since the handle 1519 is connected to the glue application head 1543 of the glue application mechanism 154 via a connecting rod, and the displacement sensor of the glue application head 1543 is already in the activated state, when the handle 1519 drives the glue application head 1543 to slide linearly in the slide groove 1542, the displacement sensor will feed back the signal to the control system, and the control system will control the glue application head 1543 to dispense glue, and the glue will fall precisely into the V-shaped groove that has been cut.

[0099] Step S4: Repeat step S3 to cut and apply adhesive until the required folding position of the PIR duct sheet is cut;

[0100] Step S5: Receiving Material - The operator releases the pressure on the long and short sides of the PIR duct sheet material by using the limiting mechanism 140 and the adjusting block mechanism 158. After rotating the two sets of pressure blocks 143 by 90° through the threaded adjusting rods 144 on both sides of the frame, the rest plate 142 that is clamped between the two sets of pressure blocks 143 by the gripping head 145 is removed. Then the cut PIR duct sheet material is removed.

[0101] Step S6: Folding and Assembly—The operator folds the PIR duct sheet based on the glued V-groove and manually applies glue to the last edge of the cut PIR duct sheet, thereby folding and bonding the two ends of the PIR duct sheet to form a rectangular cavity PIR duct.

8. An application method of the PIR duct multi-functional processing device according to any one of claims 1 to 7, characterized in that, Includes the following steps: Step S0: Preparation work - The staff installs the operating platform level (160) and the cutting mechanism level (152) on the long side of the operating platform (110) and the cutting mechanism (151) respectively, and observes and adjusts them in real time before operation; The blade is a V-shaped blade (1518), which is installed to the bottom of the blade mounting block base (1517) by fasteners; Step S1: Pressing and limiting - The PIR duct sheet to be cut is laid flat on the operating platform (110), and the middle section of the PIR duct sheet is supported by the support plate (155). The short side of the PIR duct sheet to be cut is pressed and limited by the limiting mechanism (140) on both sides of the operating mechanism (150). The long side of the PIR duct plate to be cut is limited by the adjusting stop mechanism (158) on the support plate (155) of the cutting mechanism (151). The operator marks the cutting position on the PIR duct plate to be cut according to the scale (170) on the long side of the operating platform (110); Step S2: Adjust the operating mechanism—The operator adjusts the distance between the glue application mechanism (154) and the cutting mechanism (151) in the operating mechanism (150) by adjusting the extension frame (1531) according to the required cutting size; In practical applications, the glue application mechanism (154) is located above the cutting station of the cutting mechanism (151) and is used to apply glue to the V-shaped groove that has been cut. Step S3: Cutting and gluing - The operator holds the handle (1519) of the cutting mechanism (151) and moves it linearly in the slide groove (1512). The connecting threaded rod (1515) at the bottom of the handle (1519) drives the V-shaped blade (1518) connected to the blade mounting block base (1517) to cut on the PIR duct plate to be cut through the blade mounting block (1516) connected to it. The operator removes the waste material that has been cut off from the PIR duct plate; at the same time, the driving mechanism (130) drives the operating mechanism (150) to move to the next cutting position, which is the cutting position marked in step S1. When the glue applicator (154) detects that the depth of the V-groove cut by the V-blade on the PIR duct plate meets the preset threshold through the distance sensor, it feeds back to the control system, and the control system controls the displacement sensor of the glue applicator (1543) to start. When the operator holds the handle (1519) of the cutting mechanism (151) and moves it linearly in the slide groove (1512), the PIR duct plate to be cut is cut again; the operator removes the waste material that has been cut off from the PIR duct plate again. Meanwhile, since the handle (1519) is connected to the glue application head (1543) of the glue application mechanism (154) through the connecting rod, and the displacement sensor of the glue application head (1543) is already in the start state, when the handle (1519) drives the glue application head (1543) to slide in a straight line in the second slide groove (1542), the displacement sensor will feed back the signal to the control system, and the control system will control the glue application head (1543) to dispense glue, and the glue will fall precisely into the V-shaped groove that has been cut. Step S4: Repeat step S3 to cut and apply adhesive until the required folding position of the PIR duct plate is cut; Step S5: The operator releases the pressure on the long and short sides of the PIR duct plate by using the limiting mechanism (140) and the adjusting block mechanism (158). After rotating the two sets of pressure blocks (143) by 90° through the threaded adjusting rods (144) on both sides of the frame, the operator removes the shelf (142) that is held between the two sets of pressure blocks (143) by the gripping head (145), and then removes the cut PIR duct plate. Step S6: The operator folds the PIR duct sheet based on the glued V-groove and manually applies glue to the last edge of the cut PIR duct sheet, thereby folding and bonding the two ends of the PIR duct sheet to form a rectangular cavity PIR duct.
