Description

Technical Field

[0001] The present invention relates to the technical field of composite air duct cutting, and in particular to an automatic composite air duct cutting and grooving device and an application method thereof. Background Art

[0002] Composite ducts are ventilation ducts made from a combination of various materials, typically with a central insulation layer and metal decorative panels on both sides. These sandwich panels are formed through continuous production. These ducts offer advantages such as flame retardancy, lightweight aesthetics, energy conservation and environmental protection, mildew and antibacterial properties, thermal insulation, moisture and sound insulation, quick and easy installation, stable physical properties, high thermal insulation, and high strength. They offer significant advantages in material performance, fabrication and installation, and economic efficiency. Slab cutting and grooving are crucial steps in composite ducting, and the quality of their construction directly impacts subsequent duct leakage testing, particularly affecting indoor cleanliness and energy efficiency.

[0003] When conventional composite ducts leave the factory, they can generally be installed according to the specific dimensions on site. The processing method is as follows: first, the rectangular composite duct sheet is cut, usually manually. Generally, operators need to stand opposite each other and measure the dimensions of the long side of the composite duct sheet. One of the operators holds the blade to cut, and the other operator standing opposite is responsible for observing whether the cutting lines are aligned with the marks. At the same time, heavy objects are also needed to press down the composite duct sheet to prevent displacement during the cutting process, which may lead to product cutting errors. Then, after the cutting is completed, a worker is required to apply glue on the cut surface and fold it.

[0004] To sum up, the disadvantages of artificial duct grooving mainly include the following:

[0005] 1. Complicated process: Currently, composite duct sheet materials are usually cut manually. Multiple measurements and markings are required before cutting the metal surface and the intermediate insulation layer. Typically, four cuts are required to form a V-shaped groove.

[0006] 2. Inefficiency: The layout and measurement need to be repeated every time the plate is replaced.

[0007] 3. High labor cost: Manual cutting generally requires two workers to cooperate synchronously in measuring, laying out, positioning and cutting, which requires a high degree of cooperation from the workers.

[0008] 4. The quality of the cut is difficult to guarantee: When manual cutting is performed, the plate is usually not fixed, and the plate can easily move and slide on a simple cutting workbench, which can easily cause the groove to be skewed, which is not conducive to the later duct assembly requirements. Summary of the Invention

[0037] The present invention also provides an application method of the automatic cutting and grooving device for composite air ducts, comprising the following steps:

[0038] Step S0: Preparation

[0039] First, the locking mechanism at the bottom of the auxiliary operating platform is locked and connected with the latch hole on the upper latch mechanism through a latch, thereby fixing the horizontal angle of the operating platform when it serves as a supporting plane;

[0040] Step S01: Pre-adjusting the pressing assembly of the pressing and cutting mechanism, the operator uses the handle to slide upward through the guide shaft in the arc-shaped hole to lift the pressing plate driven by the handle. The arc of the arc-shaped hole is higher at the top and lower at the bottom. The height of the pressing plate is maintained by the guide shaft staying at the highest point of the arc-shaped hole.

[0041] Step S02: Presetting parameters in the control system, including fine-tuning parameters of the fine-tuning mechanism and operating parameters of the servo motor;

[0042] Step S1: Material placement and fixing

[0043] Step S11: placing the composite air duct material to be cut on the support frame and support ribs of the operating platform;

[0044] Step S12: Using a side pressure mechanism to fix one side of the composite air duct material, ensuring that the V-shaped groove is located away from the support rib, rotating the locking screw, and clamping one side of the composite air duct material with the C-shaped pressure block to prevent it from shifting during the cutting process;

[0045] Step S2: Cutting preparation

[0046] Step S21: measuring and marking the positions to be cut on the composite air duct material according to the scales on the two support frames on the operating platform;

[0047] Step S22: The handle is slid downward in the arc-shaped hole to lower the height of the pressing plate. The pressing plate connected to the handle compresses the composite duct material by its own weight. The handle is released. The composite duct material is now compressed by the weight of the pressing plate. At the same time, the cutting blade assembly is precisely adjusted by the fine-tuning mechanism to adjust the position of the cutting blade assembly.

[0048] Step S3: Cutting operation

[0049] Step S31: Start the control system, control the servo motor to start, drive the ball screw to rotate, and drive the cutting knife group along the ball screw through the ball nut to achieve linear displacement cutting; the cutting knife group maintains the stability and accuracy of the linear cutting process with the assistance of the transverse slider on the transverse guide rail;

[0050] Step S32: After the first section of cutting is completed, the control system is stopped and the pressing assembly and the side pressing mechanism are released;

[0051] Step S33: The pressing and cutting mechanism is driven to slide to the next cutting point on the operating platform by the displacement mounting frame, and steps S2 to S3 are repeated until all cutting is completed;

[0052] In addition, after completing the cutting of all V-shaped grooves, it is necessary to adjust the position of the cutting knife group and increase the cutting depth of the cutting knife group so that the blade can cut through the composite air duct material;

[0053] Step S4: Cutting completion and material removal

[0054] Step S41: Stop the control system and release the pressing assembly and the side pressing mechanism;

[0055] Step S42: taking out the processed composite air duct material;

[0056] Step S5: Platform storage

[0057] Step S51: If the device needs to be stored, the auxiliary folding mechanism is operated as follows: the latch that locks the locking mechanism and the latch hole on the upper buckle mechanism is pulled out to unlock the connection between the upper buckle mechanism and the locking mechanism, the folding rod is rotated so that its bottom rotates on the lower rotating device, the folding rod is folded and leans against the nearest inclined support, and the upper buckle mechanism at the bottom of the operating platform is operated;

[0058] Step S52: Flip the operating platform downward. After it is folded into place, the latch hole of the upper buckle mechanism at the bottom of the operating platform is connected to the latch hole on the buckle locking block by a latch to stabilize the angle of the folded operating platform.

[0059] Step S6: Inspection and maintenance

[0060] Step S61: Check the wear of the blades of the cutting knife group and replace the blades if necessary to ensure the quality of the next cutting; Step S62: Check and clean the support base and displacement guide rail to ensure the long-term stable operation of the device.

[0061] Compared with the prior art, the present invention has the following beneficial effects:

[0062] (1) The present invention uses the C-shaped pressure block and locking screw in the side pressure mechanism to firmly fix the material during the cutting process, avoiding cutting errors caused by material displacement. The pressure plate of the pressing assembly of the pressing cutting mechanism further stabilizes the material to ensure a smooth cut.

[0063] (2) The present invention realizes linear displacement cutting by combining a cutting knife group with a ball screw, a transverse guide rail and a servo motor, and the cutting path is precise. In addition, the fine-tuning mechanism of the cutting knife group can provide two-way adjustment by fine-tuning the longitudinal guide rail and the transverse guide rail to ensure the accurate position of the tool.

[0064] (3) The operating platform of the present invention adopts a combination of a support frame, support ribs and a triangular support frame to provide stable working support. The triangular support structure of the support base forms a stable support frame through the top support rod and the longitudinal support rod, ensuring that the platform does not shake during processing.

[0065] (4) The auxiliary folding mechanism of the present invention realizes the folding and storage of the operating platform through the cooperation of the folding rod, the locking mechanism and the upper buckle mechanism. After folding, it is fixed by the buckle locking block to maintain the stability of the storage state.

[0066] (5) The present invention realizes partial automation control of the cutting mechanism, reduces manual operation and improves safety. The blade limit groove design of the cutting knife group facilitates blade replacement, and the ball screw and guide rail structure are easy to clean and maintain. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0082] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0083] like Figures 1 to 8 and Figure 11 As shown, an automatic cutting and grooving device for composite air ducts disclosed in the present invention is used for cutting rectangular composite air duct materials 7, including an operating platform 1, a side pressing mechanism 2, a pressing and cutting mechanism 3 and a control system 6.

[0084] The operating platform 1 is a rectangular frame, the bottom of which is supported on a flat surface by a support base 4, providing a work surface for placing and cutting the composite duct material 7. The operating platform 1 comprises a support frame 1-1, support ribs 1-2, and displacement guides 1-3. The support frames 1-1 are two parallel frames, and the support ribs 1-2 are multiple. The multiple support ribs 1-2 are evenly arranged and welded between the two support frames 1-1 to provide support for the composite duct material 7.

[0085] Two displacement guide rails 1-3 are used, which are respectively arranged on the sides of the two support frames 1-1. The two ends of the pressing and cutting mechanism 3 are connected to the sliders on the displacement guide rails 1-3 through the displacement mounting frame 3-3; the pressing and cutting mechanism 3 is displaced on the two support frames 1-1 to achieve cutting of the composite air duct material 7 at multiple positions.

[0086] Furthermore, in this embodiment, the support base 4 of the operating platform 1 is provided with rollers, which are respectively arranged on the extension bars of the crossbar support rod 4-2, for easy movement and transportation. The operating platform 1 is provided with handles at both ends for easy handling and transportation after folding.

[0087] The side pressure mechanism 2 is provided on one short side of the operating platform 1 and is used to press down on one side of the composite air duct material 7 to prevent displacement during cutting. The side pressure mechanism 2 includes two C-shaped pressure blocks 2-1, which are connected by a pressure block connecting plate 2-2. The C-shaped pressure blocks 2-1 are clamped to the top and bottom of one short side of the operating platform 1.

[0088] Screw holes are respectively provided on the C-shaped pressing block 2-1 and the pressing block connecting plate 2-2. In this embodiment, three adjustment screw holes are provided on the top of the C-shaped pressing block 2-1, a screw hole is provided on the vertical surface of the C-shaped pressing block 2-1, and a screw hole is provided in the center of the pressing block connecting plate 2-2. These screw holes are respectively connected to a locking screw 2-4 through threads. By rotating the locking screw 2-4, the composite air duct material 7 of the operating platform 1 can be pressed or loosened, thereby achieving the effect of pressing one side of the composite air duct material 7.

[0089] The pressing and cutting mechanism 3 is positioned between the two long sides of the operating platform 1 via a displacement mechanism and is parallel to the short sides of the operating platform 1. The length of the long side of the operating platform 1 defines the maximum displacement range of the pressing and cutting mechanism 3, while the length of the short side of the operating platform 1 defines the maximum cutting range of the pressing and cutting mechanism 3. The pressing and cutting mechanism 3 is controlled by a control system 6 to cut the composite air duct material 7.

[0090] The pressing and cutting mechanism 3 includes a pressing assembly 3-1 and a cutting assembly 3-2; a longitudinal guide rail 3-1-4 is provided on one side of the cutting assembly 3-2, and a side of the pressing assembly 3-1 is slidably connected to the longitudinal guide rail 3-1-4 via a slider to achieve guided lifting of the pressing assembly 3-1;

A pressing plate 3-1-7 is provided at the bottom of the pressing frame 3-1-1 to increase the area for pressing the composite air duct material 7. The pressing frame 3-1-1 is provided with an arc-shaped hole 3-1-5. The handle 3-1-2 is positioned within the arc-shaped hole 3-1-5 via a guide shaft. One end of the handle 3-1-2 is connected to the pressing plate 3-1-7 via the handle rotating seat 3-1-3. The sliding range of the guide shaft within the arc-shaped hole 3-1-5 drives the pressing plate 3-1-7 connected to the handle 3-1-2 to rise and fall within this sliding range, thereby compressing or loosening the composite air duct material 7.

[0092] The cutting assembly 3-2 includes a cutting frame 3-2-1, a ball screw 3-2-2, a transverse guide rail 3-2-3, a cutting blade assembly 3-2-4, and a servo motor 3-2-7. The two ends of the cutting frame 3-2-1 are slidably mounted on the operating platform 1 via displacement mounting brackets 3-3. The servo motor 3-2-7 is mounted on one side of the cutting frame 3-2-1. The output shaft of the servo motor 3-2-7 is connected to the ball screw 3-2-2 to provide drive. The transverse guide rail 3-2-3 is located above the ball screw 3-2-2.

[0093] Furthermore, in order to improve the cutting accuracy, the cutting knife group 3-2-4 of this embodiment is set on the transverse slider 3-2-6 through a fine-tuning mechanism. The fine-tuning mechanism can adopt existing technology and only needs to realize transverse and longitudinal adjustments. In this embodiment, a longitudinal guide rail device and a transverse guide rail device for adjusting the transverse and longitudinal directions are proposed. The longitudinal guide rail device is connected to the ball nut through a bracket, and the longitudinal slider on the longitudinal guide rail is connected to the transverse guide rail device through a bracket. The transverse slider on the transverse guide rail device is connected to the cutting knife group 3-2-4 through a bracket; the cutting knife group 3-2-4 realizes transverse sliding on the transverse guide rail device through the transverse slider, and realizes longitudinal sliding on the longitudinal guide rail device through the longitudinal slider connected to the transverse guide rail.

[0094] In this embodiment, if Figure 10 As shown, the cutting knife group 3-2-4 includes two groups of symmetrically arranged knife holders, the knife holder 8 includes a combined shell and a blade 8-1, the combined shell includes an upper shell 8-2 and a lower shell 8-3, and the lower shell 8-3 is provided with a blade limiting groove 8-4 for accurately installing the position of the blade 8-1; the upper shell 8-2 and the lower shell 8-3 are connected by fasteners to install the fixed blade 8-1.

[0095] Furthermore, in this embodiment, a pair of handles 3-1-6 are installed on the pressing frame 3-1-1 of the pressing mechanism 3-1 to facilitate pressing and lifting the pressing mechanism 3-1.

[0096] The support base 4 includes three sets of triangular support frames, which include two oblique supports 4-1 and a transverse connecting rod 4-2. The tops of the two oblique supports 4-1 are connected, and the bottoms of the two oblique supports 4-1 are connected by a transverse connecting rod 4-2 to form a triangular frame structure.

[0097] The tops of the three sets of triangular support frames are respectively arranged at the bottom of the operating platform 1 through support connection components 4-4; the tops and bottoms of the three sets of triangular support frames are respectively connected in series through top support rods 4-6 and longitudinal support rods 4-3, providing a stable triangular support structure for the operating platform 1;

[0098] Further, if Figure 12 As shown, to facilitate transportation and movement, in this embodiment, an auxiliary folding mechanism 5 is also provided at the bottom of the operating platform 1. The auxiliary folding mechanism 5 includes a folding rod 5-2, a locking mechanism 5-4, and an upper snap mechanism 5-3. The upper snap mechanism 5-3 is disposed at the bottom of the operating platform 1. The bottom of the folding rod 5-2 is pivotally mounted on a horizontal bar extending from the transverse connecting rod 4-2 via a lower rotating device 5-1. The top of the folding rod 5-2 is detachably connected to the upper snap mechanism 5-3 via a latch 5-5 via a locking mechanism 5-4. The support connection assembly 4-4 is pivotally connected to the bottom of the operating platform 1 via a rotating shaft.

[0099] Furthermore, in this embodiment, a snap locking block 4-5 with a pin hole is provided on the inclined support 4-1 near the folding rod 5-2. After folding, the pin hole of the upper snap mechanism 5-3 at the bottom of the operating platform 1 and the pin hole of the snap locking block 4-5 are connected by a pin passing through the inside and locked, thereby fixing the angle of the operating platform 1 after folding.

[0100] like Figure 13 As shown, the present invention also provides an application method of the composite air duct multifunctional processing device, comprising the following steps:

[0101] Step S0: Preparation

[0102] First, the locking mechanism 5-4 at the bottom of the auxiliary operating platform 1 is locked and connected with the latch hole 5-5 on the upper latch mechanism 5-3 through a latch, thereby fixing the horizontal angle of the operating platform 1 when it serves as a supporting plane;

[0103] Step S01: Pre-adjust the pressing assembly 3-1 of the pressing and cutting mechanism 3. The operator uses the handle 3-1-2 to slide upward through the guide shaft in the arc-shaped hole 3-1-5 to lift the pressing plate 3-1-7 driven by the handle 3-1-2. The arc of the arc-shaped hole 3-1-5 is higher at the top and lower at the bottom. The height of the pressing plate 3-1-7 is maintained by the guide shaft staying at the highest point of the arc-shaped hole 3-1-5.

[0104] Step S02: Presetting the parameters in the control system 6, including the fine-tuning parameters of the fine-tuning mechanism and the operating parameters of the servo motor;

[0105] Step S1: Material placement and fixing

[0106] Step S11: placing the composite air duct material 7 to be cut on the support frame 1 - 1 and the support rib 1 - 2 of the operating platform 1 ;

[0107] Step S12: Use the side pressure mechanism 2 to fix one side of the material, rotate the locking screw 2-4, and clamp one side of the composite air duct material 7 through the C-shaped pressure block 2-1 to prevent it from shifting during the cutting process;

[0108] Step S2: Cutting preparation

[0109] Step S21: measuring and marking the position on the composite air duct material (7) where cutting is required according to the scales on the two support frames (1-1) on the operating platform (1);

[0110] Step S22: Slide the handle 3-1-2 downward in the arc-shaped hole 3-1-5 to lower the height of the pressing plate 3-1-7. The pressing plate 3-1-7 connected to the handle 3-1-2 compresses the composite air duct material 7 by its own weight. Release the handle 3-1-2. At this time, the composite air duct material 7 is compressed by the weight of the pressing plate 3-1-7.
