Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to a foam cutting device and a process thereof. Background Art

[0002] Foam is a porous, soft and breathable material, mainly made of plastic materials such as polyester and polyether. It has excellent heat insulation, sound insulation and shockproof properties. It is a practical composite material and is widely used in various equipment, products and buildings. There are many types of foam materials, including polyurethane foam, polyester foam, polyethylene foam, etc. Polyurethane foam has good sound insulation and heat insulation properties, polyester foam is often used for packaging, sound insulation, etc., while polyethylene foam is suitable for packaging protection and sound insulation and heat insulation materials.

[0003] When processing foam, it is generally necessary to use a laser cutter to cut the foam into a suitable size. For example, a multi-angle adjustable laser cutting device for foam is disclosed in Chinese utility model patent publication number CN222588431U. In this technology, a laser is used to generate heat to cut the foam. However, when the laser is cut, a large amount of heat is generated on the cut surface of the foam. After the cutting is completed, the cut surface of the foam is burned by the residual heat, so that a carbonized layer is formed on the cut surface of the foam. The carbonized layer will affect the quality of the cut surface of the foam to a certain extent. However, the above-mentioned technology does not take corresponding measures to improve the phenomenon of the carbonized layer. Therefore, the field is in urgent need of a laser cutting device or equipment that can reduce the phenomenon of the carbonized layer on the cut surface of the foam during laser cutting. Summary of the invention

[0004] The object of the present invention is to provide a foam cutting device and a process thereof to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: A foam cutting device, comprising: A rack and a material shelf mechanism installed in the middle of the rack; A moving beam horizontally slidably connected to the top of the frame; A mounting seat horizontally slidably connected to the top of the moving beam, wherein the movement direction of the mounting seat on the moving beam is perpendicular to the movement direction of the moving beam on the frame; A laser mounted on the mounting seat, wherein a laser head is mounted at the lower end of the laser; A first mounting ring sleeved on the periphery of the laser, wherein the periphery of the first mounting ring is hinged with a swing arm; A distribution mechanism provided at the lower end of the swing arm; An inert gas blowing pipe is connected to the periphery of the first mounting ring.

[0006] Through the above technical scheme, the slit formed by the laser head cutting is opened by the distribution mechanism, thereby expanding the upper side opening of the slit, and the inert gas is blown into the upper side opening of the slit by the inert gas blowing tube. The inert gas will have a protective effect on the cut end face of the foam in the slit, thereby preventing the residual heat from burning the cut surface of the foam. In addition, since the upper side opening of the slit is opened, the inert gas can be blown to the cut surface of the foam more smoothly. In addition, since the slit is opened, the distance between the two relative cutting surfaces is increased, thereby avoiding the mutual influence of the residual heat of the two cutting surfaces.

[0007] Furthermore, each of the four corners on the top of the frame is rotatably connected to a synchronous pulley, and a synchronous belt is commonly wrapped around the two synchronous pulleys located on both sides of the moving direction of the moving beam, and the two ends of the moving beam in the length direction are respectively fixed to the two synchronous belts, and the two synchronous pulleys corresponding to the two sides in the length direction of the moving beam and located on the same side of the frame are connected through a transmission rod, and one of the synchronous pulleys is driven to rotate by a first servo motor installed on the top of the frame.

[0008] Through the above technical solution, the first servo motor drives one of the synchronous pulleys to rotate, thereby making the four synchronous pulleys rotate synchronously, and the two synchronous belts will synchronously drive the two ends of the moving beam to move, thereby realizing the horizontal movement of the moving beam on the top of the frame.

[0009] Furthermore, a second servo motor is installed on the top of the movable beam, and a screw rod is also connected to the top of the movable beam for horizontal rotation. The second servo motor is drivingly connected to the screw rod, and the screw rod is threadedly penetrated through the mounting seat.

[0010] Through the above technical solution, the second servo motor drives the screw rod to rotate, and the screw rod cooperates with the mounting seat, thereby driving the mounting seat to move on the top of the moving beam.

[0011] Furthermore, the material racking mechanism includes a lifting frame arranged in the middle of the frame, a plurality of strip-shaped pointed plates are provided on the top of the lifting frame, a plurality of rotating screws are vertically rotatably connected to the frame, a lifting bracket is threadedly mounted on the peripheral edge of the rotating screw, the upper end of the lifting bracket is connected to the lifting frame, a third servo motor is installed on the frame, and the third servo motor drives the plurality of rotating screws to rotate synchronously through a transmission member.

[0012] Through the above technical solution, the third servo motor drives multiple rotating screws to rotate, and then the rotating screws are screwed together with the threads of the lifting bracket, thereby driving the lifting bracket to drive the lifting frame to perform lifting movements, so that the height of the foam placed on the surface of the strip pointed plate can be adjusted, thereby adjusting the cutting depth of the foam.

[0013] Furthermore, a second mounting ring is installed on the periphery of the laser, a movable hinge seat is hinged on the periphery of the second mounting ring, a finger cylinder is installed on the movable hinge seat, the cylinder rod of the finger cylinder is fixedly connected to a connecting block, a hinge rod is fixedly connected to the surface of the swing arm, and one end of the hinge rod away from the swing arm is hinged to the connecting block.

[0014] Through the above technical solution, the cylinder rod of the finger cylinder is extended and retracted to drive the connecting block to move up and down. When the connecting block moves up and down, the hinge rod is driven to swing along the hinge of the swing arm at the periphery of the first mounting ring, thereby driving the swing arm to swing up and down.

[0015] Furthermore, the first mounting ring and the second mounting ring are both rotatably connected to the periphery of the laser, and the periphery of the second mounting ring is provided with an angle adjustment unit.

[0016] Through the above technical solution, since the first mounting ring and the second mounting ring are both rotatably connected to the periphery of the laser, the rotation angle of the distribution mechanism around the laser can be adjusted, thereby making the distribution mechanism adapt to cutting in different directions.

[0017] Furthermore, the angle adjustment unit includes a bolt mounting block fixedly connected to the periphery of the second mounting ring, and a fastening bolt is horizontally threaded through the outer wall of the bolt mounting block, and the fastening bolt presses against the periphery of the laser to lock and stop the second mounting ring.

[0018] Through the above technical solution, the fastening bolt is threadedly screwed on the bolt mounting block until the end of the fastening bolt is pressed against the periphery of the laser, thereby locking the second mounting ring, so that the distribution mechanism is in a locked state after the angle adjustment is completed.

[0019] Furthermore, the distribution mechanism comprises a columnar portion horizontally fixed to the lower end of the swing arm, two sliding pins are slidably penetrated at both ends of the columnar portion, and one end of the sliding pin passing through the columnar portion is fixedly sleeved with a distribution frame; The opposite ends of the two dividing racks are each vertically fixed with a dividing plate, and the lower end of the dividing plate is provided with an inserting plate, and the thickness of the inserting plate is smaller than the thickness of the dividing plate; A spreading drive assembly is arranged in the columnar portion, and the spreading drive assembly is used for driving the two distribution racks to move in directions away from each other.

[0020] Through the above technical solution, the driving assembly drives the two dividing frames to move away from each other, so that the two dividing plates can open the slits on the foam, and after the two dividing plates are combined, they can be inserted into the slits of the foam.

[0021] Furthermore, the pushing-apart drive assembly includes a magnetic slider fixedly sleeved on the other end of the sliding pin, a sliding cavity is provided in the cylindrical portion for the magnetic slider to slide freely, an electromagnet is provided in the sliding cavity, the electromagnet is located between the two magnetic sliders, and an elastic member is provided between the electromagnet and the two magnetic sliders, the elastic member gives the magnetic slider potential energy to move in a direction away from the electromagnet.

[0022] Through the above technical scheme, the electromagnet generates magnetism when energized, thereby generating magnetic attraction on the magnetic slider, so that the two magnetic sliders respectively drive the two sliding pins to move in the direction of approaching each other, thereby merging the two dividing plates, and the elastic part accumulates elastic potential energy. When the electromagnet is powered off, it loses its magnetism, and the elastic potential energy accumulated in the elastic part is released, thereby driving the two magnetic sliders to move in the direction of moving away from each other, thereby causing the two dividing plates to move in the direction of moving away from each other.

[0023] A foam cutting process, applied to the cutting device as described above, comprises: Place the foam to be cut flat on the shelf mechanism, and move the moving beam on the frame to move the laser and the laser head to the processing position; The laser is started, so that the laser head starts to laser cut the surface of the foam. When a slit is cut on the surface of the foam, the swing arm swings downward, and the dividing mechanism is inserted into the slit, and then the upper side of the slit is opened, so that the width of the upper side of the slit is greater than the width of the lower side; The external inert gas delivery equipment delivers the inert gas to the inert gas blowing pipe, which then blows the inert gas toward the narrow gap formed at the cutting part by the laser head. Since the distribution mechanism expands the narrow gap that has been processed, the inert gas can smoothly enter the narrow gap formed at the cutting part, and then the end face of the cutting part is protected by the inert gas.

[0024] Through the above technical solution, the burning of the foam cutting surface by residual heat is reduced, thereby reducing the generation of the carbonized layer. In addition, the distribution mechanism can pry open the upper side opening of the slit to allow the inert gas to be blown smoothly into the slit.

[0025] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the slit formed by the laser head cutting is opened by the distribution mechanism, thereby expanding the upper side opening of the slit, and the inert gas is blown into the upper side opening of the slit by the inert gas blowing pipe. The inert gas will have a protective effect on the cut end surface of the foam in the slit, thereby preventing the residual heat from burning the cut surface of the foam. In addition, since the upper side opening of the slit is opened, the inert gas can be blown to the cut surface of the foam more smoothly. In addition, since the slit is opened, the distance between the two opposite cut surfaces is increased, thereby avoiding the mutual influence of the residual heat of the two cut surfaces; 2. In the present invention, the third servo motor drives the plurality of rotating screws to rotate, and then the rotating screws are screwed together with the threads of the lifting bracket, thereby driving the lifting bracket to drive the lifting frame to perform lifting movement, so that the height of the foam placed on the surface of the strip pointed plate can be adjusted, thereby adjusting the cutting depth of the foam; 3. In the present invention, since the first mounting ring and the second mounting ring are both rotatably connected to the periphery of the laser, the rotation angle of the distribution mechanism around the laser can be adjusted, thereby making the distribution mechanism adapt to cutting in different directions.

[0030] Working principle of the present invention: The foam to be cut is placed flat on the strip pointed plate 3, and then the first servo motor 6 is started. When the motor shaft of the first servo motor 6 rotates, it can drive a synchronous pulley on the upper right side of the frame 1 to rotate, and then through the transmission of the synchronous belt 5, the synchronous pulley on the lower right side of the frame 1 also rotates synchronously. In addition, through the transmission of the transmission rod 7, the two synchronous pulleys on the left side of the frame 1 also rotate. The two ends of the moving beam 4 in the length direction are respectively connected to the belt bodies of the two synchronous belts 5. For example, the belt body of the synchronous belt 5 can be connected to the end surface of the moving beam 4 by rivets, so that when the synchronous belt 5 moves, it can drive the moving beam 4 to move horizontally on the top of the frame 1; Then, by starting the second servo motor 9, the second servo motor 9 drives the screw rod 10 to rotate. When the screw rod 10 rotates, it is screwed with the thread of the internal thread slider 11, thereby driving the internal thread slider 11 and the mounting seat 13 to move horizontally, so that the laser head 12 moves to the processing position; The external inert gas delivery device delivers the inert gas (such as nitrogen) to the inert gas blowing pipe 17 and blows it to the bottom of the laser head 12. The laser 22 works and generates laser light, which is emitted by the laser head 12 and starts to cut the foam. During cutting, the first servo motor 6 drives the synchronous pulley to rotate, so that the moving beam 4 moves horizontally on the top of the frame 1, so that the laser head 12 starts to cut the foam in a straight line. During cutting, the cylinder rod of the finger cylinder 23 extends to drive the connecting block 24 to move downward. When the connecting block 24 moves downward, it drives the hinge rod 25 to swing downward along the swing arm 26 at the hinge of the periphery of the first mounting ring 16, thereby driving the swing arm 26 to swing, so that the swing arm 26 approaches the top surface of the foam, and finally the slit piece 29 on the dividing piece 28 is inserted into the formed slit; The control cabinet of the laser cutting equipment controls the electromagnet 33 to be powered off and lose its magnetism. Under the action of the elastic potential energy of the elastic member 34, the two magnetic sliders 32 respectively drive the two sliding pins 31 to move away from each other, so that the dividing plate 28 has a prying effect on the slit, thereby increasing the width of the upper side opening of the slit. After the slit opening is enlarged, the inert gas can fully enter the slit and form a protective layer in the slit, reducing the oxygen content in the slit. In this way, when the laser head 12 continues to cut, due to the residual heat in the slit, the amount of oxygen contacted by the residual heat is reduced, and the cutting surface of the foam will not be burned, reducing the production of the carbonized layer. After the straight line cutting is completed, the cylinder rod of the finger cylinder 23 is shortened, and the slot inserting piece 29 is driven to move upward, and then the electromagnet 33 is energized again, so that the two slot inserting pieces 29 can be merged for the next operation.

The external inert gas delivery device delivers the inert gas to the inert gas blowing pipe (17), and then the inert gas blowing pipe (17) blows the inert gas toward the fine crack formed at the cutting portion of the laser head (12). Since the distribution mechanism expands the fine crack formed by the processing, the inert gas can smoothly enter the fine crack formed at the cutting portion, and then the end face of the cutting portion is protected by the inert gas.
