Description

Technical Field

[0001] The invention relates to the technical field of cloth cutting, and in particular to a laser cutting device for cloth used in clothing manufacturing. Background Art

[0002] In the process of clothing design and manufacturing, large pieces of fabric need to be cut. Laser cutting is to focus the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the clothing fabric, causing the clothing fabric to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting.

[0003] At present, when cutting fabrics using laser cutting devices, the fabrics are usually laid flat on the cutting table directly, and the function of straightening the fabrics is lacking, which can easily lead to uneven and wrinkled fabrics, affecting the quality of clothing cutting. At the same time, the cutting process will also produce some irritating odors, which can easily cause harm to the staff. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the background technology and to provide a laser cutting device for fabrics used in clothing manufacturing.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A laser cutting device for fabrics used in garment manufacturing, comprising:

[0007] A frame, wherein two conveying rollers are symmetrically rotatably mounted in the frame, a conveying belt is sleeved between the two conveying rollers, and a driving motor for driving one of the conveying rollers is fixedly mounted on the outer side of the frame;

[0008] A lifting plate is slidably sleeved on the frame, an electric push rod for driving the lifting plate is fixedly installed in the frame, and a fixed plate is fixedly installed on the top of the lifting plate;

[0009] A pressing and straightening assembly is used to flatten the cloth on the surface of the conveyor belt;

[0010] A mobile cutting assembly is used to cut the cloth;

[0011] The smoke exhaust component is used to exhaust the smoke generated when the movable cutting component cuts the cloth.

[0012] Preferably, the compression and straightening assembly includes two rotating rollers rotatably mounted on the front side of a fixed plate, two worm gears coaxially connected to the two rotating rollers are rotatably mounted on the outer side of the fixed plate, worms are meshed on the upper sides of the two worm gears, and a dual-axis motor for driving the two worms is fixedly mounted on the outer side of the fixed plate.

[0013] Preferably, the movable cutting assembly includes a support plate fixedly mounted on the front side of the fixed plate, a movable block slidingly penetrates the top of the support plate, a laser cutting head is fixedly mounted on the bottom of the movable block, and a motor is fixedly mounted on the top of the movable block, a gear is fixedly mounted on the driving end of the motor, a rack is meshed at the bottom of the gear, and the rack is fixedly mounted on the outer side of the support plate.

[0014] Preferably, the smoke exhaust assembly includes an annular pipe fixedly installed on the outside of the laser cutting head by multiple support rods, and the annular pipe is sleeved on the outside of the laser cutting head, a plurality of smoking holes are opened at the bottom of the annular pipe, and the outside of the annular pipe is fixedly connected to a hose, the other end of the hose is fixedly connected to a suction pump, and the suction pump is fixedly installed on the outside of the motor, and a filter is installed at the exhaust port of the suction pump.

[0015] Preferably, a limiting plate is fixedly sleeved on the outer wall of the moving block, and the limiting plate is slidably fitted to the bottom of the supporting plate, and a sliding hole slidably connected to the moving block is opened on the top of the supporting plate.

[0016] Preferably, a switch is fixedly mounted on the frame, and the switch is electrically connected to the dual-axis motor.

[0017] Preferably, a control panel and a processor are installed on the rack.

[0018] Preferably, a positioning plate is fixedly mounted on the top of the frame, and the top of the positioning plate is slidably fitted to the inner top of the conveyor belt.

[0019] Preferably, a fixing block is rotatably mounted on the opposite ends of the two worms, and the fixing block is fixedly mounted on the outer side of the fixing plate.

[0020] Compared with the prior art, the advantages of the laser cutting device for fabrics used in clothing manufacturing provided by the present invention are:

[0021] 1. The electric push rod pushes the lifting plate downward, so that the fixed plate drives the two rotating rollers to move downward synchronously until the two rotating rollers press the clothing fabric tightly. At this time, the dual-axis motor controls the two worms to rotate, so that the two worm gears drive the two rotating rollers to rotate in the opposite direction, and the clothing fabric can be straightened and flattened under the friction between the worm and the clothing fabric to prevent the clothing fabric from becoming loose during the cutting process and affecting the cutting quality;

[0022] 2. By starting the motor to control the gear to rotate and make it roll along the rack, the laser cutting head can be driven to move above the clothing fabric through the moving block.

When the laser cutting head is cutting the clothing fabric, start the suction pump, and the smoke generated during cutting can be sucked into the filter through the hose and the annular pipe, and then discharged in a centralized manner after being filtered by the filter to prevent the smoke from spreading and affecting the operation of the operator;

[0024] In summary, the present invention uses two rotating rollers that can be raised and lowered and rotated in opposite directions. When the rollers come into contact with clothing fabric, they can straighten and flatten the clothing fabric under friction, so as to prevent the clothing fabric from becoming loose during the cutting process and affecting the cutting quality. At the same time, when cutting the fabric, the suction pump can be started, and the smoke generated during cutting can be sucked into the filter through the hose and the annular pipe, and then discharged in a concentrated manner after being filtered by the filter, thereby reducing the harm to the staff.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0032] Reference Figures 1 to 5 , a laser cutting device for fabrics used in garment manufacturing, comprising:

[0033] A frame 1 is provided with a control panel 25 and a processor 26. Two conveying rollers 2 are symmetrically rotatably installed in the frame 1. A conveyor belt 3 is sleeved between the two conveying rollers 2. A driving motor 4 for driving one of the conveying rollers 2 is fixedly installed on the outer side of the frame 1. The cloth to be cut is placed on the conveyor belt 3, and then the driving motor 4 is started to control the rotation of the conveying roller 2 connected thereto. Then, with the cooperation of the other conveying roller 2, the conveyor belt 3 is operated to automatically convey the clothing cloth.

[0034] The lifting plate 5 is slidably sleeved on the frame 1 , an electric push rod 6 for driving the lifting plate 5 is fixedly installed in the frame 1 , and a fixed plate 7 is fixedly installed on the top of the lifting plate 5 .

[0035] The pressing and straightening assembly is used to flatten the cloth on the surface of the conveyor belt 3. The pressing and straightening assembly includes two rotating rollers 8 rotatably installed on the front side of the fixed plate 7. Two worm wheels 9 coaxially connected to the two rotating rollers 8 are rotatably installed on the outer side of the fixed plate 7. A worm 10 is meshed on the upper side of the two worm wheels 9. A double-axis motor 11 for driving the two worms 10 is fixedly installed on the outer side of the fixed plate 7. The opposite ends of the two worms 10 are rotatably installed with fixed blocks 28, and the fixed blocks 28 are fixedly installed on the outer side of the fixed plate 7. When the part of the clothing cloth to be cut moves to the corresponding position of the laser cutting head 14, the electric push rod 6 is started to push the lifting plate 5 to move downward, so that the fixed plate 7 drives the two rotating rollers 8 to move downward synchronously until the two rotating rollers 8 press the clothing cloth. At this time, the double-axis motor 11 controls the two worms 10 to rotate, so that the two worm wheels 9 drive the two rotating rollers 8 to rotate in the opposite direction, and the clothing cloth can be straightened and flattened under the friction between the two worm wheels and the clothing cloth to prevent the clothing cloth from being loosened during the cutting process and affecting the cutting quality.

[0036] The mobile cutting assembly is used to cut the cloth. The mobile cutting assembly includes a positioning plate 27 fixedly installed on the top of the frame 1, and the top of the positioning plate 27 slides and fits against the support plate 12 on the front side of the inner top fixed plate 7 of the conveyor belt 3. The top of the support plate 12 slides through a moving block 13. The outer wall of the moving block 13 is fixedly sleeved with a limiting plate 23, and the limiting plate 23 slides and fits against the bottom of the support plate 12. The top of the support plate 12 is provided with a sliding hole 15 that is slidably connected to the moving block 13, which plays a role in limiting the limiting plate 23, and with the cooperation of the positioning plate 27, the limiting plate 23 can move radially along the sliding hole 15.

[0037] A laser cutting head 14 is fixedly installed at the bottom of the moving block 13, and a motor 16 is fixedly installed at the top of the moving block 13. A gear 17 is fixedly installed at the driving end of the motor 16. A rack 18 is meshed at the bottom of the gear 17, and the rack 18 is fixedly installed on the outer side of the support plate 12. When cutting, the motor 16 is first started to control the rotation of the gear 17 so that it rolls along the rack 18, and the laser cutting head 14 can be driven to move above the clothing fabric through the moving block 13. At the same time, the laser cutting head 14 can be started to cut the clothing fabric. After cutting, the two rotating rollers 8 can be moved up by the electric push rod 6, and then the clothing fabric can be transported by the conveyor belt 3, thereby improving the cutting efficiency of the clothing fabric.

[0038] The smoke exhaust component is used to exhaust the smoke generated when the mobile cutting component cuts cloth. The smoke exhaust component includes an annular pipe 19 fixedly installed on the outside of the laser cutting head 14 through multiple support rods, and the annular pipe 19 is sleeved on the outside of the laser cutting head 14. A plurality of smoking holes are opened at the bottom of the annular pipe 19, and a hose 21 is fixedly connected to the outside of the annular pipe 19. The other end of the hose 21 is fixedly connected to a suction pump 20, and the suction pump 20 is fixedly installed on the outside of the motor 16. A filter 22 is installed at the discharge port of the suction pump 20. When the laser cutting head 14 cuts clothing cloth, the suction pump 20 is started, and the smoke generated during cutting can be sucked into the filter 22 through the hose 21 and the annular pipe 19, and then discharged in a concentrated manner after being filtered by the filter 22, thereby reducing the harm to the staff.

[0039] Furthermore, a switch 24 is fixedly installed on the frame 1, and the switch 24 is electrically connected to the dual-axis motor 11. The switch 24 is located above the lifting plate 5. When the lifting plate 5 is pushed down by the electric push rod 6, it will break away from the resistance to the switch 24. Therefore, the dual-axis motor 11 can control the two rotating rollers 8 to rotate in opposite directions when it is energized. That is, when the rotating rollers 8 come into contact with the cloth, they can automatically straighten and flatten it. When the lifting plate 5 moves up and touches the switch 24, the dual-axis motor 11 will automatically cut off the power, which has a certain automation effect.

[0040] The working principle of the present invention is:

[0041] When in use, the cloth to be cut is first placed on the conveyor belt 3, and then the driving motor 4 is started to control the conveyor roller 2 connected thereto to rotate, so that the conveyor belt 3 is operated with the cooperation of another conveyor roller 2, and the clothing cloth is automatically conveyed;

[0042] When the portion of the garment fabric to be cut moves to the position corresponding to the laser cutting head 14, the electric push rod 6 is started to push the lifting plate 5 downward, so that the fixed plate 7 drives the two rotating rollers 8 to move downward synchronously until the two rotating rollers 8 press the garment fabric tightly. At the same time, the lifting plate 5 will be free from the resistance to the switch 24, so the dual-axis motor 11 is energized to control the two worms 10 to rotate, so that the two worm wheels 9 drive the two rotating rollers 8 to rotate in the opposite direction, and the garment fabric can be straightened and flattened under the friction between the two worm wheels 9 and the garment fabric;

[0043] Then, the motor 16 is started to control the gear 17 to rotate, so that it rolls along the rack 18, and the laser cutting head 14 can be driven to move above the clothing fabric through the moving block 13. At the same time, the laser cutting head 14 can be started to cut the clothing fabric, and after cutting, the two rotating rollers 8 can be moved up by the electric push rod 6, and then the clothing fabric is transported by the conveyor belt 3, thereby improving the cutting efficiency of the clothing fabric;

[0044] At the same time, the suction pump 20 can also be started, and the smoke generated during cutting can be sucked into the filter 22 through the hose 21 and the annular pipe 19, and then discharged after being filtered by the filter 22.

[0045] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
