Description

Technical Field

[0001] This invention belongs to the field of laser cutting equipment technology, specifically an intelligent laser garment cutting bed and cutting method. Background Technology

[0002] Currently, traditional cutting methods mainly rely on manual or mechanical cutting. Manual cutting is greatly affected by human factors, making it difficult to guarantee consistency in each cut. Furthermore, it is more prone to generating waste and increasing production costs when cutting intricate patterns. Laser cutting machines, combining modern laser technology and automated control technology, can achieve high-precision and high-efficiency cutting in the garment manufacturing industry, and have become an important production equipment in modern garment manufacturing. However, existing laser cutting machines, such as the invention patent with publication number CN104499264A, although capable of pre-cutting and marking fabrics, actually... The rapid production of modern clothing presents challenges. During the cutting process, the laser beam is easily affected by wrinkles on the fabric surface, making it difficult to focus accurately. This leads to deviations in the cutting path and results in shapes that do not match expectations. Furthermore, variations in fabric thickness across different areas affect laser penetration and cutting effectiveness, causing uneven edges or even jagged edges. While some cutting beds employ side-pulling mechanisms to achieve a degree of horizontal fabric spreading and flatness, excessive lateral pulling at the cut area can deform the fabric, directly impacting the cut shape.

[0003] Therefore, it is necessary to provide an intelligent laser garment cutting bed and cutting method to solve the problems mentioned in the background art. Summary of the Invention

[0018] Furthermore, as a preferred embodiment, the main roller and the auxiliary roller respectively spray drying gas from the upper and lower surfaces of the formed fabric through air holes and connecting holes.

[0019] Furthermore, preferably, the pneumatic propulsion mechanism includes:

[0020] A sealing gas seat has a positioning sleeve fixed at its center. The positioning sleeve is coaxially sleeved on the outside of the laser generator, and an annular compartment is formed between the positioning sleeve and the sealing gas seat.

[0021] A push ring is slidably connected inside the annular chamber. Multiple fixing rods are provided below the push ring, and the other end of each fixing rod is connected to the ironing plate.

[0022] A lifting spring is sleeved on each of the fixed rods, and one end of the lifting spring is connected to the push ring;

[0023] The upper end cover is fitted and fixed above the positioning sleeve. The upper end cover has a guide cavity inside.

An air extraction pipe is also provided outside the sealed air seat, and the air extraction pipe is connected to the air extraction channel.

[0025] Furthermore, as a preferred embodiment, the lower end face of the ironing plate is symmetrically provided with a first guide groove, a second guide groove and a third guide groove, the first guide groove, the second guide groove and the third guide groove are all arranged in the same circle, and a tension plate is slidably connected in both of the first guide grooves;

[0026] The second guide groove and the third guide groove have internal holes.

[0027] Furthermore, as a preferred embodiment, a lever is symmetrically and rotatably installed inside the ironing plate, and a straight groove is formed inside the lever. The straight groove is always intersecting with the first guide groove during the adjustment of the lever rotation. A positioning pin is vertically fixed above the tension plate, and the positioning pin is slidably connected in the straight groove.

[0028] The ironing plate has a sealed cavity, and a piston is slidably connected in the sealed cavity. A T-shaped connecting rod is fixed outside the piston, and the two ends of the T-shaped connecting rod are connected to each of the lever plates through side rods.

[0031] A cutting method for an intelligent laser garment cutting bed includes the following steps:

[0032] S1. Fabric preparation: The fabric roller frame is manually placed on the main body of the cutting bed, while the shaped fabric is wound and conveyed to the front ironing unit. The cutting pattern of the garment piece is imported into the control system of the laser cutting mechanism.

[0033] S2. Parameter settings: Adjust the laser power and speed parameters in the laser cutting mechanism according to the type and thickness of the fabric being formed; perform starting point positioning calibration on the laser generator;

[0034] S3. Pre-ironing and pressing adjustment: Based on the cutting standards of the shaped fabric, the main roller and the auxiliary roller perform a pre-ironing and pressing operation on the shaped fabric.

[0035] S4. Laser cutting: The laser cutting mechanism is driven by a three-axis frame to perform cutting operations along the pre-input cutting pattern. The ironing plate can make low-pressure contact with the surface of the shaped fabric under the pneumatic force of the pneumatic mechanism, so that the tension plate below can expand and shape the pre-cutting trajectory through the rotation adjustment of the dial plate. The inner holes in the second and third guide grooves blow hot air onto the shaped fabric. The hot air flows and diffuses along the second and third guide grooves, thereby achieving an adaptive ironing effect on the fabric around the cutting trajectory.

[0036] S5. Post-processing: Allow the cut areas of the shaped fabric to cool naturally and heat-seal the edges.

[0037] Compared with the prior art, the beneficial effects of the present invention are:

[0038] In this invention, the intelligent laser garment cutting bed is mainly equipped with a pre-ironing unit to pre-iron the shaped fabric, so that the shaped fabric as a whole meets the laser cutting standard and ensures the flatness of each position of the shaped fabric. The laser cutting mechanism can perform secondary adaptive ironing on the cutting trajectory through the ironing plate during the cutting process, thereby effectively improving the cutting accuracy and edge quality. Among them, the ironing plate can make low-pressure contact with the surface of the shaped fabric through the air push mechanism, avoiding excessive pressure on the shaped fabric and surface deformation during the movement of the ironing plate, while protecting the shaped fabric to a certain extent and reducing thermal damage to the fabric.

[0048] Please see Figures 1-8 In this embodiment of the invention, an intelligent laser garment cutting bed includes:

[0049] The main body of the cutting bed 1 has two mounting positions in the middle of its upper end face, and a first transmission belt 11 and a second transmission belt 12 are horizontally arranged at each mounting position.

[0050] The fabric roller frame 13 is horizontally rotatably mounted on the cutting bed body 1 on one side near the first transmission belt 11, and the fabric roller frame 13 is wound with shaped fabric.

[0051] The pre-ironing unit 2 is set on the side of the cutting bed body 1 near the fabric roller frame 13. The pre-ironing unit 2 is set parallel to the bottom of the fabric roller frame 13. The pre-ironing unit 2 is used to pre-iron the shaped fabric so that the thickness and surface hardness of the shaped fabric meet the laser cutting standard.

[0052] The upper pressure roller 14 is rotatably connected to the cutting bed body 1 and located above the end of the first transmission belt 11. The upper pressure roller 14, in conjunction with the first transmission belt 11, horizontally transmits and spreads the pre-ironed shaped fabric on the first transmission belt 11. When the shaped fabric is spread on the first transmission belt 11 and the second transmission belt 12, it can be synchronously horizontally transmitted with the first transmission belt 11 and the second transmission belt 12 under the action of contact friction.

[0053] A three-axis frame 15 is horizontally mounted on the cutting bed body 1 and located directly above the second transmission belt 12. A laser cutting mechanism 3 is installed at the transfer end of the three-axis frame 15. The laser cutting mechanism 3 cuts garment pieces from the shaped fabric spread on the second transmission belt 12. The three-axis frame 15 can drive the laser cutting mechanism 3 to move freely in the X, Y, and Z axes.

[0054] The laser cutting mechanism 3 includes an upper base 31, which is horizontally fixed on the Z-axis sliding plate 16 of the three-axis frame 15. A turntable 32 is rotatably connected below the upper base 31, and a laser generator 33 is vertically mounted below the turntable 32. An ironing plate 5 is slidably sleeved on the outside of the laser generator 33. An air-push mechanism 4 is provided on the laser generator 33. One end of the air-push mechanism 4 is connected to the ironing plate 5. The air-push mechanism 4 uses air force to push the ironing plate 5 downward, so that the ironing plate 5 contacts the surface of the shaped fabric with low pressure. Thus, the ironing plate 5 adaptively irons the cutting point. In other words, the ironing plate 5 can adaptively iron the cutting trajectory of the shaped fabric during laser cutting by the laser generator 33. On the one hand, it ensures the flatness of the fabric before laser cutting and improves the subsequent cutting accuracy and consistency. On the other hand, the air-push mechanism can control the ironing plate 5 to contact the surface of the shaped fabric with low pressure, avoiding excessive deformation and damage to the shaped fabric.

[0055] In this embodiment, the turntable 32 can ensure that the ironing plate 5 is always facing and aligned with the cutting trajectory of the laser generator 33 during forward and reverse rotation adjustment, thereby ensuring the consistency of ironing the cutting trajectory and guaranteeing the cutting quality.

[0056] In a preferred embodiment, the pre-ironing unit 2 includes:

[0057] The main roller 21 is rotatably connected to the cutting bed body. The main roller 21 has a shaft layer wall 23 at its inner center. A number of connecting ribs 24 are distributed between the shaft layer wall 23 and the inner wall of the main roller 21. The connecting ribs 24 are equidistantly distributed in a circle.

[0058] Steam channel 26 is centrally located at one end of the main roller 21, and one end of the steam channel 26 is connected to the shaft wall 23;

[0059] A diameter hole 25 is formed on each of the connecting ribs 24, and each of the diameter holes 25 is connected to the shaft layer wall 23. A steam pipe is connected to the outside of the main roller 21, and one end of the steam pipe is sealed and rotatably connected to the main roller 21. The high-temperature steam in the steam pipe can enter the shaft layer wall 23 through the steam channel 26, and then be blown onto the surface of the shaped fabric through each diameter hole 25 outside the shaft layer wall 23.

[0060] The first hot air channel is centrally located at the other end of the main roller 21. Multiple air holes 27 are distributed on the side wall of the main roller 21, and each air hole 27 is staggered with the diameter hole 25. High-temperature steam can form multiple penetration points on the surface of the shaped fabric through each diameter hole 25, while the air holes 27 can blow dry gas around each penetration point to quickly evaporate the moisture on the surface of the fabric. Through the combination of high-temperature steam and dry gas, the fabric is ensured to meet the expected standards before cutting.

[0061] The auxiliary roller 22 is rotatably connected to the cutting bed body 1 and is located above the main roller 21. Multiple connecting holes 28 are distributed on the side wall of the auxiliary roller 22, and a second hot air channel is provided at one end of the auxiliary roller 22.

[0062] In this embodiment, the main roller 21 and the auxiliary roller 22 respectively spray drying gas from the top and bottom of the shaped fabric through the air hole 27 and the connecting hole 28. Double-sided drying can remove moisture from the surface of the fabric more evenly and prevent deformation caused by uneven drying in some areas. This design is suitable for a variety of fabrics, including cotton, polyester and so on.

[0063] In this embodiment, the pneumatic propulsion mechanism 4 includes:

[0064] The sealing gas seat 41 has a positioning sleeve fixed at its center. The positioning sleeve is coaxially sleeved on the outside of the laser generator 33, and an annular compartment is formed between the positioning sleeve and the sealing gas seat 41.

[0065] The push ring 42 is slidably connected in the annular chamber. A plurality of fixing rods 43 are provided below the push ring 42, and the other end of each fixing rod 43 is connected to the ironing plate 5.

[0066] A lifting spring is sleeved on each of the fixed rods 43, and one end of the lifting spring is connected to the push ring 42;

[0067] The upper end cover 44 is sleeved and fixed above the positioning sleeve. The upper end cover 44 has a guide cavity 45 inside. The positioning sleeve has multiple air passages distributed around its circumference. Each air passage is vertically aligned with the push ring 42. One side of the sealing air seat 41 is connected to a pressure pipe. The sealing air seat 41 has an air inlet (not shown in the figure). The pressure pipe is sealed and connected to one end of the air inlet. The other end of the air inlet is connected to the guide cavity 45.

[0068] An air extraction channel 46 is provided in the sealing air seat 41. One end of the air extraction channel 46 is connected to the upper end of the inner wall of the annular chamber. An air extraction pipe 47 is also provided outside the sealing air seat 41. The air extraction pipe 47 is connected to the air extraction channel 46. The airflow sent in by the air inlet can form a downward air push effect on the push ring 42 from above through each air channel, while the air extraction channel 46 can discharge the airflow in time, so that the ironing plate 5 can achieve low-pressure contact with the shaped fabric.

[0069] In this embodiment, the lower end face of the ironing plate 5 is symmetrically provided with a first guide groove 51, a second guide groove 52 and a third guide groove 53. The first guide groove 51, the second guide groove 52 and the third guide groove 53 are all arranged in the same circle, and a tension plate 54 is slidably connected in both of the first guide grooves 51.

[0070] The second guide groove 52 and the third guide groove 53 are provided with inner holes 55.

[0071] In a preferred embodiment, a lever 56 is symmetrically and rotatably installed inside the ironing plate 5. A straight groove is formed inside the lever 56. The straight groove is always intersected with the first guide groove 51 during the rotation adjustment of the lever 56. A positioning pin 57 is vertically fixed above the tension plate 54. The positioning pin 57 is slidably connected in the straight groove.

[0072] The ironing plate 5 has a sealed cavity 58, and a piston is slidably connected in the sealed cavity 58. A T-shaped connecting rod 511 is fixed outside the piston. The two ends of the T-shaped connecting rod 511 are connected to each of the lever plates 56 through side rods. When the piston slides axially under hydraulic pressure, it can push each lever plate 56 to deflect through the T-shaped connecting rod 511. This causes the positioning pin 57 to slide along the first guide groove 51 through the straight groove on the lever plate 56, so that the tensioning plates 54 in the two first guide grooves 51 can locally tension the fabric on both sides of the cutting track.

[0073] A direct current liquid channel 59 is provided on one side of the ironing plate 5, which is connected to the sealed cavity 58. A pulse liquid channel 510 is also provided on one side of the direct current liquid channel 59 inside the ironing plate 5. Specifically, the oil in the sealed cavity 58 is quantitatively adjusted through the direct current liquid channel 59 so that the tension plates 54 in the two first guide grooves 51 reach a certain designated position (initial position) of the first guide grooves 51. Then, the pulse liquid channel 510 performs normal operation. The piston continuously drives the lever 56 to deflect in the forward and reverse directions through the T-shaped connecting rod 511 so that the tension plates 54 in the first guide grooves 51 can generate corresponding sliding displacement, thereby forming a continuous tensioning operation on the fabric on both sides of the cutting track. The different initial positions of the tension plates 54 have a direct impact on the tensioning effect during operation. That is, as the initial position of the tension plates 54 is adjusted to the left and right, the tension strength of the tension plates 54 on the shaped fabric during the tensioning operation becomes weaker and weaker.

[0074] In this embodiment, the ironing plate 5 is provided with a drying channel, which is connected to each of the inner holes 55, and a heat flow pipe is connected to the outside of the drying channel.

[0075] In this embodiment, a cutting method for an intelligent laser garment cutting bed includes the following steps:

[0076] S1. Fabric preparation: The fabric roller frame 13 is manually placed on the main body of the cutting bed 1, and the shaped fabric is simultaneously wound and conveyed to the front ironing unit 2. The cutting pattern of the garment piece is imported into the control system of the laser cutting mechanism 3. The control system generates a precise laser cutting path according to the imported cutting pattern to ensure the accuracy and consistency of the cutting.

[0077] S2. Parameter settings: Adjust the laser power and speed parameters in the laser cutting mechanism 3 according to the type and thickness of the fabric being formed. Thicker or stiffer fabrics require higher laser power to ensure complete penetration. Perform starting point positioning calibration on the laser generator 33 (a positioning sensor or vision system can be used to assist in the calibration).

[0078] S3. Pre-ironing adjustment: Based on the cutting standard of the shaped fabric, the main roller 21 and the auxiliary roller 22 are used to pre-iron the shaped fabric. The main roller 21 can deliver high-temperature steam to the shaped fabric through the steam channel 26 so that the shaped fabric can achieve the expected softness and smoothness.

[0079] S4. Laser cutting: The laser cutting mechanism 3 is driven by the three-axis frame 15 to perform cutting operations along the pre-input cutting pattern. The ironing plate 5 can make low-pressure contact with the surface of the shaped fabric under the pneumatic force of the pneumatic push mechanism 4, ensuring that the fabric remains flat during the cutting process and reducing cutting errors caused by fabric slippage or deformation. This allows the tension plate 54 below to expand and shape the pre-cutting trajectory through the rotation adjustment of the lever plate 56, preventing the fabric from loosening or deforming during the cutting process. The inner holes 55 in the second guide groove 52 and the third guide groove 53 blow hot air onto the shaped fabric. The hot air flows and diffuses along the second guide groove 52 and the third guide groove 53, thereby achieving an adaptive ironing effect on the fabric around the cutting trajectory.

[0080] S5. Post-processing: Allow the cut areas of the shaped fabric to cool naturally and heat-seal the edges.

[0081] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
