Description

Technical Field

[0001] The invention belongs to the field of carpet cutting, and in particular relates to a laser cutting device and a cutting method for processing a patchwork carpet. Background Art

[0002] Patchwork carpet, commonly known as "square carpet" or "assembled carpet", is a new type of flooring material with an elastic composite material as the backing and cut into squares.

[0003] As life becomes more affluent, some people have higher and higher requirements for the quality of carpets, and the higher-quality carpets are undoubtedly those with better air permeability. For example, natural fiber carpets, which are made of materials such as wool, silk, corn fiber, seaweed fiber, sisal fiber, etc., usually have good air permeability. These natural materials have good ventilation, which can ensure indoor air circulation and prevent excessive temperature and humidity.

[0004] At present, laser cutting is widely used in the cutting of patchwork carpets. This cutting method is easy to operate and has high efficiency. However, when laser cutting is performed on materials with strong air permeability, the following problems may occur:

[0005] 1. Destruction of air permeability: The high temperature generated by the laser may destroy the microporous structure inside the material, thereby affecting the air permeability of the carpet;

[0006] 2. Large cutting error: Due to problems such as uneven surface or reflection of carpet materials, the cutting error is large;

[0007] 3. The heat-affected zone is too large: During laser cutting, high temperature will produce a heat-affected zone on the edge of the material, which will cause structural damage to the material and reduce the cutting quality;

[0008] 4. Smoke pollution: A large amount of smoke and debris will be generated during the laser cutting process. The smoke will affect the air and affect the health of the workers after being inhaled. The debris will remain on the equipment, affecting the cleanliness of the equipment and the subsequent cutting accuracy.

[0009] 5. There is a risk of reflection: Some breathable materials may have reflections on their surfaces. Direct laser cutting may increase the risk of reflected light damaging the laser and the operator's eyes. Summary of the invention

[0027] In order to prevent other straws from being sucked into the film-tearing roller and causing air leakage inside the film-tearing roller, the suction force generated by the vacuum generator is made smaller than the elastic force of the second compression spring;

[0028] As the tearing roller winds the protective film, the diameter of the protective film on the tearing roller becomes larger and larger. In order not to affect the tearing roller's continued winding of the protective film, the movable mounting block is slidably connected inside the fixed frame, and a first compression spring is connected between the movable mounting block and the fixed frame.

[0030] The method for cutting a carpet using the above-mentioned laser cutting device for processing a patchwork carpet comprises the following steps:

[0031] S01: Pass one end of the carpet under the film placing assembly and the film sticking assembly and place it on the surface of the horizontal conveyor;

[0032] S02: Paste one end of the protective film on the film assembly to one end of the carpet, and use the film sticking assembly to compact the protective film, leaving a margin between the film sticking assembly and one end of the carpet; stretch the protective film and stick one end of the protective film on the carpet, then the third telescopic rod drives the film sticking roller to descend, so that the film sticking roller rolls the protective film on the carpet;

[0033] S03: Start the horizontal conveyor and the film sticking assembly, so that the film sticking assembly and the horizontal conveyor move synchronously, and the horizontal conveyor and the film sticking assembly jointly drive the carpet to move, so that one end of the carpet passes under the welding mechanism (initially, the bottom of the welding mechanism is higher than the top of the film sticking assembly) and moves to the bottom of the pressing assembly; start the horizontal conveyor and the second motor, the second motor drives the third screw to rotate, and the third screw drives the second slider to move, so that the speed at which the second slider drives the film sticking roller to move is the same as the speed at which the horizontal conveyor drives the carpet to move, so that the carpet can pull the protective film to move, and due to the existence of the anti-loosening mechanism, the protective film stays on the top of the carpet at an angle until one end of the carpet moves to the bottom of the pressing assembly;

[0034] S04: Use the pressing assembly to press one end of the carpet, and then make the film sticking assembly move in the reverse direction, so that the film sticking assembly presses the protective film on the carpet until it is close to the film placing assembly; start the fourth telescopic rod, the fourth telescopic rod drives the fixing frame to descend, and the fixing frame drives the pressing plate to descend through the connecting rod, and the pressing plate presses the carpet, and reversely starts the second motor, and the second motor drives the film sticking roller to move in the reverse direction. Since the carpet is fixed, the film sticking roller rolls on the carpet, and then the inclined protective film can be pressed on the carpet;

[0035] S05: Adjust the position of the welding mechanism, and use the welding mechanism to cut the carpet into a square; the first telescopic rod drives the cross frame to descend, so that the cross frame drives the laser welding machine body to approach the carpet, and then fine-tune the distance between the laser welding machine body and the carpet according to the thickness of the carpet to make the laser welding machine body achieve the best cutting effect. During adjustment, the first adjusting screw is rotated, and the first adjusting screw drives the lifting block to move up and down, and the lifting block drives the laser welding machine body to move up and down; then the second servo motor drives the second screw to rotate, and the second screw drives the first slider to move longitudinally, and the first slider drives the cross frame and the laser welding machine body to move longitudinally through the first telescopic rod, and the first servo motor drives the first screw to rotate, and the first screw drives the adjustment frame to move horizontally, and the adjustment frame drives the laser welding machine body to move horizontally, and the second servo motor and the first servo motor are controlled to control the direction of the laser welding machine body to form a square path, so that the carpet can be cut into a square;

[0036] S06: After the cutting is completed, the welding mechanism is raised, and the fixing of the carpet by the pressing assembly is released; the first telescopic rod drives the cross frame to rise, and the cross frame drives the laser welding machine body to rise, so that the bottom of the laser welding machine body is higher than the top of the film laminating roller, so that the film laminating roller can pass through, and then the fourth telescopic rod drives the fixing frame to rise, and the fixing frame drives the pressing plate to rise, and the fixing of the pressing plate to the carpet is released;

[0037] S07: Repeat step S03 to unload the cut carpet, and use the film-tearing mechanism to tear off the protective film on the cut carpet; the second motor drives the film-sticking roller to follow the horizontal conveyor to move again, so that the horizontal conveyor drives the carpet to stretch the protective film, and at the same time, the second telescopic rod drives the film-tearing roller to descend, so that the soft suction cup on the film-tearing roller squeezes the protective film on the carpet, and the vacuum generator is started. The vacuum generator extracts the air inside the air cavity, so that the protective film is adsorbed on the soft suction cup, and the first motor is started. The first motor drives the film-tearing roller to rotate, and the film-tearing roller winds the protective film, so that the protective film on the carpet can be torn off without manual film tearing, thereby reducing the workload of the staff;

[0038] S: Repeat steps S04 to S07 to continuously cut the carpet.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] 1. The present invention, before cutting the carpet, avoids the damage of the microporous structure inside the material by high temperature, thereby affecting its air permeability; it can also make laser cutting more accurate, and reduce the cutting error caused by the uneven surface of the material or the reflection of the material; at the same time, the coating can reduce the conduction of heat into the material, thereby reducing the range of the heat-affected zone and improving the cutting quality; the coating can also reduce the generation of smoke and debris, protect the cleanliness of the equipment and the operating environment, and improve the cutting quality; after coating, it can also reduce the risk of reflection and improve the safety of operation;

[0041] 2. In the present invention, before cutting the carpet, one end of the protective film on the film-laying assembly is pasted on one end of the carpet, and one end of the carpet is moved under the pressing assembly, and the pressing assembly is used to press one end of the carpet, and then the film-sticking assembly is moved in the reverse direction, and the film-sticking assembly presses the protective film on the carpet, so that the protective film can be completely and tightly attached to the carpet;

[0042] 3. In the present invention, when film is applied, after the toggle wheel is sleeved on the film placing roller, when the carpet pulls the protective film to move, the protective film drives the film placing roller to rotate, and the film placing roller drives the toggle wheel to rotate, the elastic paddle elastically blocks the paddle plate, and the paddle plate elastically limits the rotation of the toggle wheel and the film placing roller, so as to avoid wrinkles caused by excessive rotation of the film placing roller, thereby improving the accuracy of carpet cutting; when the toggle wheel is separated from the film placing roller, the film placing roller can be taken out of the placement groove, so as to facilitate the replacement of the film placing roller;

[0043] 4. In the present invention, the second telescopic rod drives the film-tearing roller to descend, so that the soft suction cup on the film-tearing roller squeezes the protective film on the carpet, and the vacuum generator extracts the air inside the air cavity, so that the protective film is adsorbed on the soft suction cup, and then the first motor drives the film-tearing roller to rotate, and the film-tearing roller winds the protective film, so that the protective film on the carpet can be torn off without manual film tearing, thereby reducing the workload of the staff;

[0044] 5. In the present invention, as the tearing roller winds the protective film, the diameter of the protective film on the tearing roller becomes larger and larger. In order not to affect the continued winding of the protective film by the tearing roller, the movable mounting block is slidably connected inside the fixed frame, and a first compression spring is connected between the movable mounting block and the fixed frame. When the diameter of the protective film increases, under the reaction force, the protective film lifts the tearing roller, and the tearing roller drives the movable mounting block to move upward. The first compression spring is compressed and deformed, so that the rotation of the tearing roller is not affected. Under the action of the first compression spring, the adhesion of the protective film on the tearing roller to the protective film on the carpet is increased, thereby improving the tearing effect.

The film tearing mechanism 3 is located on the side of the clamping assembly 6 away from the welding mechanism 2. The film tearing mechanism 3 is used to tear off the protective film 44 on the carpet.

[0077] like Figure 1 , Figure 8-Figure 11 As shown, a laser cutting device for processing mosaic carpets provided by the present invention is provided. In this embodiment, the film tearing mechanism 3 includes two second telescopic rods 33, the two second telescopic rods 33 are respectively fixedly connected to the two sides of the horizontal conveyor 1, the movable ends of the two second telescopic rods 33 are fixedly connected to the fixed frames 32, the interiors of the two fixed frames 32 are installed with movable mounting blocks 37, a film tearing roller 34 is rotatably connected between the two movable mounting blocks 37, an air cavity 317 is provided inside the film tearing roller 34, a first motor 31 is fixedly installed on one of the movable mounting blocks 37, the output shaft of the first motor 31 is fixedly connected to one end of the film tearing roller 34, the other end of the film tearing roller 34 is rotatably connected to a rotary joint 39, one end of the rotary joint 39 is connected to a hose 310, one end of the hose 310 is connected to a vacuum generator 36, and the vacuum generator 36 is fixedly installed on the horizontal conveyor 1;

[0078] A plurality of suction cup assemblies are installed on the film tearing roller 34, and the plurality of suction cup assemblies are evenly distributed on the film tearing roller 34;

[0079] The suction cup assembly includes a mounting cavity 314 provided inside the film-tearing roller 34, a sliding plate 312 is slidably connected inside the mounting cavity 314, a second compression spring 313 is connected between the sliding plate 312 and the side wall of the mounting cavity 314, a suction pipe 35 passes through the sliding plate 312, one end of the suction pipe 35 extending out of the film-tearing roller 34 is fixedly connected to the soft suction cup 311, an active hole 316 communicating with the mounting cavity 314 is provided on the inner wall of the air cavity 317, the other end of the suction pipe 35 is slidably connected to the active hole 316, a vent 315 is provided on the side of the suction pipe 35, the distance from the bottom of the vent 315 to the top of the air cavity 317 is smaller than the distance from the top of the suction pipe 35 to the surface of the film-tearing roller 34, and initially, the vent 315 is located inside the active hole 316;

[0080] When tearing the film, the second telescopic rod 33 drives the fixed frame 32 to descend, and the fixed frame 32 drives the movable mounting block 37 and the film tearing roller 34 to descend, so that the film tearing roller 34 drives the suction pipe 35 to squeeze the carpet, and then the soft suction cup 311 is blocked by the protective film 44. Under the reaction force, the suction pipe 35 is squeezed into the installation cavity 314, and the vent 315 is connected with the air cavity 317, and the vacuum generator 36 is started. The vacuum generator 36 extracts the air in the air cavity 317 through the hose 310, and the air in the suction pipe 35 is also extracted from the vent 315. Under atmospheric pressure, the protective film 44 is adsorbed on the soft suction cup 311;

[0081] In order to prevent other suction tubes 35 from being sucked into the film-tearing roller 34 and causing air leakage inside the film-tearing roller 34, the suction force generated by the vacuum generator 36 is made smaller than the elastic force of the second compression spring 313;

[0082] The first motor 31 is started, and the first motor 31 drives the film tearing roller 34 to rotate. The film tearing roller 34 winds up the protective film 44 on the carpet, so that the protective film 44 on the carpet can be torn off. After the protective film 44 is wound around the film tearing roller 34 for one circle, the head and tail of the protective film 44 are bonded to each other, and the adhesive surface of the protective film 44 faces outward. At this time, the vacuum generator 36 can be turned off, and the protective film 44 on other carpets can be adhered to by the adhesive surface of the protective film 44, and then wound. As the film tearing roller 34 winds up the protective film 44, the diameter of the protective film 44 on the film tearing roller 34 becomes larger and larger. In order not to affect the continuous winding of the protective film 44 by the film tearing roller 34, the movable mounting block 37 is slidably connected to the inside of the fixed frame 32, and a first compression spring 38 is connected between the movable mounting block 37 and the fixed frame 32.

[0083] When the diameter of the protective film 44 increases, under the reaction force, the protective film 44 lifts up the film tearing roller 34, and the film tearing roller 34 drives the movable mounting block 37 to move upward. The first compression spring 38 is compressed and deformed, so that the rotation of the film tearing roller 34 is not affected, and the adhesion of the protective film 44 on the film tearing roller 34 to the protective film 44 on the carpet can be increased, thereby improving the film tearing effect.

[0084] Directions:

[0085] S01: Pass one end of the carpet through the bottom of the film placing assembly 4 and the film sticking assembly 5, and place it on the surface of the horizontal conveyor 1;

[0088] S04: Use the pressing component 6 to press one end of the carpet, and then make the film sticking component 5 move in the reverse direction, and the film sticking component 5 presses the protective film 44 on the carpet until it is close to the film placing component 4; start the fourth telescopic rod 61, the fourth telescopic rod 61 drives the fixing frame 62 to descend, and the fixing frame 62 drives the pressing plate 64 to descend through the connecting rod 63, and the pressing plate 64 presses the carpet, and reversely starts the second motor 51, and the second motor 51 drives the film sticking roller 52 to move in the reverse direction. Since the carpet is fixed, the film sticking roller 52 rolls on the carpet, and then the inclined protective film 44 can be pressed on the carpet;

[0089] S05: Adjust the position of the welding mechanism 2, and use the welding mechanism 2 to cut the carpet into a square; the first telescopic rod 22 drives the cross frame 25 to descend, so that the cross frame 25 drives the laser welding machine body 29 to approach the carpet, and then fine-tune the distance between the laser welding machine body 29 and the carpet according to the thickness of the carpet, so that the laser welding machine body 29 can achieve the best cutting effect. When adjusting, turn the first adjusting screw 27, the first adjusting screw 27 drives the lifting block 28 to rise and fall, and the lifting block 28 drives the laser welding machine body 29 to rise and fall; then the second servo motor 210 drives The second screw rod 211 is driven to rotate, the second screw rod 211 drives the first slider 23 to move longitudinally, the first slider 23 drives the cross frame 25 and the laser welding machine body 29 to move longitudinally through the first telescopic rod 22, the first servo motor 21 drives the first screw rod 24 to rotate, the first screw rod 24 drives the adjustment frame 26 to move transversely, the adjustment frame 26 drives the laser welding machine body 29 to move transversely, the second servo motor 210 and the first servo motor 21 are controlled to turn in a direction, so that the path of the laser welding machine body 29 forms a square, so that the carpet can be cut into a square;

[0090] S06: After the cutting is completed, the welding mechanism 2 is raised, and the fixing of the carpet by the pressing assembly 6 is released; the first telescopic rod 22 drives the cross frame 25 to rise, and the cross frame 25 drives the laser welding machine body 29 to rise, so that the bottom of the laser welding machine body 29 is higher than the top of the film laminating roller 52, so that the film laminating roller 52 can pass through, and then the fourth telescopic rod 61 drives the fixing frame 62 to rise, and the fixing frame 62 drives the pressing plate 64 to rise, and the fixing of the pressing plate 64 to the carpet is released;

[0091] S07: Repeat step S03 to unload the cut carpet, and use the film-tearing mechanism 3 to tear off the protective film 44 on the cut carpet; the second motor 51 drives the film-sticking roller 52 to follow the horizontal conveyor 1 to move again, so that the horizontal conveyor 1 drives the carpet to stretch the protective film 44, and at the same time, the second telescopic rod 33 drives the film-tearing roller 34 to descend, so that the soft suction cup 311 on the film-tearing roller 34 squeezes the protective film 44 on the carpet, and the vacuum generator 36 is started. The vacuum generator 36 extracts the air inside the air cavity 317, so that the protective film 44 is adsorbed on the soft suction cup 311, and the first motor 31 is started. The first motor 31 drives the film-tearing roller 34 to rotate, and the film-tearing roller 34 wraps around the protective film 44, so that the protective film 44 on the carpet can be torn off without manual film tearing, thereby reducing the workload of the staff;
