Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, and more specifically to an adjustable umbrella fabric laser cutting device. Background Technology

[0002] In the manufacturing process of umbrellas, the cutting of the umbrella fabric is a crucial step. Traditional umbrella fabric cutting often uses mechanical stamping or die-cutting methods, which have problems such as low cutting precision, easy fraying of edges, and inability to cut complex shapes. With the development of laser technology, laser cutting has been gradually applied to the processing of umbrella fabrics due to its advantages such as high cutting precision, high speed, and smooth cut edges.

[0003] For example, a novel umbrella fabric cutting device for umbrella production, disclosed in prior art (CN111893727A), uses a first motor to drive a rotating plate to rotate. The rotating plate, through a first connecting rod, a support plate, a hydraulic cylinder, a first fixed plate, a second connecting rod, and a second fixed plate, drives the cutting blade to rotate. This allows the cutting blade to flexibly and accurately change the cutting angle, enabling the device to cut triangular umbrella fabric of various sizes and areas, thus expanding the processing range of the device and improving its practicality.

[0004] However, existing laser cutting devices for umbrella fabric require manual flattening of the fabric before cutting to prevent wrinkles from affecting the cutting quality. However, manual flattening is inefficient and the results are unstable. Furthermore, even after flattening, the fabric is still prone to shifting and wrinkling, which in turn affects the cutting accuracy. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, the present invention provides an adjustable umbrella fabric laser cutting device. By setting an adjustment mechanism and a flattening bar, the device can effectively flatten and guide the umbrella fabric, and also fix the umbrella fabric during the cutting process, greatly improving the flatness of the umbrella fabric and ensuring the accuracy and quality of subsequent cutting. Furthermore, the vertical position of the flattening bar can also be adjusted by a first electric push rod to adapt to umbrella fabrics of different thicknesses, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable umbrella fabric laser cutting device, comprising a cutting table, a laser cutting mechanism mounted on the top of the cutting table for cutting umbrella fabric, two symmetrically distributed flattening strips inside the cutting table, a sliding groove on the inner wall of the front end of the cutting table, an adjustment mechanism for adjusting the position of the flattening strips inside the sliding groove, a feeding roller rotatably mounted on one side of the cutting table, and a winding roller rotatably mounted on the other side of the cutting table, the feeding roller and the winding roller cooperating to automatically feed umbrella fabric, and a dust suction mechanism fixedly mounted inside the cutting table.

[0007] In a preferred embodiment, the laser cutting mechanism includes a top plate, on which a three-dimensional adjustment component is fixedly mounted. A laser cutting head is mounted on the three-dimensional adjustment component. The three-dimensional adjustment component can realize the movement and adjustment of the laser cutting head in the X, Y, and Z directions, thereby improving the cutting flexibility.

[0008] In a preferred embodiment, the adjusting mechanism includes a slider disposed inside a slide groove. A slide rail is fixedly disposed on the top of the slider. A first lead screw is rotatably disposed inside the slide rail. Two first nut blocks are threadedly connected to the first lead screw. The two first nut blocks are respectively fixed to two push-flat strips. Rotation of the first lead screw can drive the two first nut blocks to move relative to or towards each other along the slide rail, thereby adjusting the distance between the two push-flat strips to adapt to umbrella fabrics of different widths and ensure the pushing-flat effect.

[0009] In a preferred embodiment, a first motor is fixedly mounted on one side of the top of the slider. The output shaft of the first motor passes through the slide rail and is fixed to one end of the first lead screw, which is used to drive the first lead screw to rotate, thereby realizing the automatic adjustment of the distance between the two push bars, reducing the intensity of manual operation, and improving the adjustment efficiency and accuracy.

[0010] In a preferred embodiment, the bottom of the slide groove is provided with an installation groove and two limiting holes. A first electric push rod is fixedly installed inside the installation groove. The top end of the piston rod of the first electric push rod is fixed to the bottom of the slider. Limiting rods that are adapted to the limiting holes are fixed on both sides of the bottom of the slider. The limiting rods are located in the limiting holes. The first electric push rod can drive the slider to move up and down along the slide groove, thereby adjusting the height of the push bar. The cooperation between the limiting rods and the limiting holes can prevent the slider from deviating during movement and ensure the stability of the push bar adjustment.

[0011] In a preferred embodiment, the dust collection mechanism includes a dust collection hopper installed inside the cutting table. The top of the dust collection hopper is fixed with a plurality of equally spaced grid plates. The top edge of each grid plate is chamfered. The chamfer design can prevent the edge of the grid plate from scratching the umbrella fabric and ensure the integrity of the umbrella fabric surface.

[0012] In a preferred embodiment, a support frame is fixedly provided at the bottom of the cutting table, and a vacuum cleaner is fixedly provided at the top of the support frame. An air pipe is connected to the air inlet of the vacuum cleaner. One end of the air pipe passes through the dust collection hopper and communicates with the inside of the dust collection hopper. A first guide roller is provided between two adjacent grid plates. The first guide roller is rotatably installed on the top of the dust collection hopper to support the movement of the umbrella fabric, reduce the friction of the umbrella fabric, and prevent the umbrella fabric from wrinkling or being damaged.

[0013] In a preferred embodiment, a second motor is fixedly inserted through the center of the rear end of the cutting table. A second lead screw is fixedly provided at the front end of the output shaft of the second motor. The front end of the second lead screw is rotatably connected to the inner wall of the front end of the cutting table. A second nut block is threaded onto the second lead screw. A push plate is fixedly provided on the top of the second nut block. The second nut block is located between two adjacent first guide rollers. The second motor drives the second lead screw to rotate, thereby driving the second nut block and the push plate to move back and forth. This can push the cut umbrella fabric waste to a designated position, facilitating the centralized cleaning of waste and improving processing efficiency.

[0014] In a preferred embodiment, a fixing groove is provided on both sides of the top of the cutting table, and a second electric push rod is fixedly embedded in the bottom wall of each of the two fixing grooves. A lifting block is fixedly provided at the top of the piston rod of the second electric push rod. The feeding roller and the winding roller are respectively installed on the top of the two lifting blocks. The second electric push rod can drive the lifting blocks to move up and down, thereby adjusting the height of the feeding roller and the winding roller, and realizing the adjustment of the tension of the umbrella fabric.

[0015] In a preferred embodiment, a third motor is fixedly provided at the rear end of each of the two lifting blocks, which drives the feeding roller and the winding roller to rotate respectively. A second guide roller is fixedly provided on the side of the two lifting blocks that are close to each other. The third motor provides power for the rotation of the feeding roller and the winding roller, realizing the automated conveying of umbrella fabric and improving processing efficiency. At the same time, the second guide roller can guide the umbrella fabric during the conveying process, ensuring the stability of the umbrella fabric conveying and avoiding the umbrella fabric deviation.

[0016] The technical effects and advantages of this invention are as follows: 1. By setting an adjustment mechanism and a flattening bar, the umbrella fabric can be effectively flattened and guided, and the umbrella fabric can be fixed during the cutting process, which greatly improves the flatness of the umbrella fabric and ensures the accuracy and quality of subsequent cutting. The vertical position of the flattening bar can also be adjusted by the first electric push rod to adapt to umbrella fabrics of different thicknesses. 2. The height of the feeding roller and the winding roller are automatically adjusted by the second electric push rod and the lifting block. With the help of the liftable push plate, which is driven by the second motor, the second lead screw and the second nut block, the waste generated by cutting can be pushed out from the top of the grid plate after cutting, which is convenient for operators to collect and improves the convenience and safety of material handling. 3. By setting up a dust collection mechanism, the combination of a vacuum cleaner, a dust collection bucket, and a grid plate can promptly suck in and collect the smoke and lint generated during laser cutting, effectively purifying the working environment and protecting the health of operators. The chamfered edge design of the grid plate can prevent scratches on the umbrella fabric. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Refer to the instruction manual appendix Figures 1-8This invention provides an adjustable umbrella fabric laser cutting device, including a cutting table 1. A laser cutting mechanism 2 is installed on the top of the cutting table 1 for cutting umbrella fabric. The laser cutting mechanism 2 includes a top plate 201. A three-dimensional adjustment component 202 is fixedly installed on the top of the top plate 201. A laser cutting head 203 is installed on the three-dimensional adjustment component 202. The three-dimensional adjustment component 202 can adopt the XYZ axis linear module in the prior art. The three-dimensional adjustment component 202 can drive the laser cutting head 203 to move in the X, Y, and Z directions, thereby realizing the cutting of umbrella fabric at different positions and of different sizes.

[0021] The cutting table 1 has two symmetrically distributed flattening strips 3 inside. The inner wall of the front end of the cutting table 1 has a sliding groove 4. The sliding groove 4 has an adjustment mechanism 5 for adjusting the position of the flattening strips 3. A feeding roller 6 is rotatably provided on one side of the cutting table 1, and a winding roller 7 is rotatably provided on the other side of the cutting table 1. The feeding roller 6 and the winding roller 7 cooperate to automatically feed the umbrella fabric.

[0022] And, as Figures 1-3 , Figure 7 and Figure 8 As shown, a fixing groove 17 is provided on both sides of the top of the cutting table 1. A second electric push rod 18 is fixedly embedded in the bottom wall of each of the two fixing grooves 17. A lifting block 19 is fixedly provided at the top of the piston rod of the second electric push rod 18. The feeding roller 6 and the winding roller 7 are respectively installed on the top of the two lifting blocks 19. A third motor 20 is fixedly provided at the rear end of each of the two lifting blocks 19, which drives the feeding roller 6 and the winding roller 7 to rotate respectively. A second guide roller 21 is fixedly provided on the side of the two lifting blocks 19 that is close to each other, which is used to guide the umbrella fabric and facilitate feeding and winding.

[0023] The adjustment mechanism 5 includes a slider 501 disposed inside the slide groove 4. A slide rail 502 is fixedly disposed on the top of the slider 501. A first lead screw 503 is rotatably disposed inside the slide rail 502. Two first nut blocks 504 are threadedly connected to the first lead screw 503. The two first nut blocks 504 are respectively fixed to two push flat bars 3. A first motor 505 is fixedly disposed on one side of the top of the slider 501. The output shaft of the first motor 505 passes through the slide rail 502 and is fixed to one end of the first lead screw 503, and is used to drive the first lead screw 503 to rotate.

[0024] In this embodiment, both the first motor 505 and the third motor 20 can be forward and reverse servo motors, which have high positioning accuracy and fast dynamic response. They can also smoothly adjust the position of the two push bars 3. In addition, threads with opposite helical directions are machined on both sides of the outer wall of the first lead screw 503 to drive the two first nut blocks 504 to move in similar or opposite directions.

[0025] To improve the stability of the slider 501's lifting and lowering, such as Figure 5 and Figure 6 As shown, an installation groove 9 and two limiting holes 10 are provided at the bottom of the slide groove 4. A first electric push rod 11 is fixedly installed inside the installation groove 9. The top end of the piston rod of the first electric push rod 11 is fixed to the bottom of the slider 501. By extending and retracting the first electric push rod 11, the slider 501 can be driven to move up and down in the slide groove 4, thereby driving the entire push bar 3 assembly to rise and fall. Limiting rods 12 that are adapted to the limiting holes 10 are fixed on both sides of the bottom of the slider 501. The limiting rods 12 are set in the limiting holes 10 and slide in the corresponding limiting holes 10, playing a guiding and stabilizing role.

[0026] like Figures 1-4 and Figure 8 As shown, a dust collection mechanism 8 is fixedly installed inside the cutting table 1. The dust collection mechanism 8 includes a dust collection hopper 801 installed inside the cutting table 1. A plurality of equally spaced grid plates 802 are fixedly installed on the top of the dust collection hopper 801. The top edge of each grid plate 802 is chamfered. A support frame 803 is fixedly installed at the bottom of the cutting table 1. A vacuum cleaner 804 is fixedly installed on the top of the support frame 803. An air pipe 805 is connected to the air inlet of the vacuum cleaner 804. One end of the air pipe 805 passes through the dust collection hopper 801 and communicates with the inside of the dust collection hopper 801. A first guide roller 806 is provided between two adjacent grid plates 802. The first guide roller 806 is rotatably installed on the top of the dust collection hopper 801 to support the movement of the umbrella fabric.

[0027] When the vacuum cleaner 804 is working, a negative pressure is generated in the dust collection hopper 801, which draws the dust generated during laser cutting into the dust collection hopper 801 through the mesh plate 802, and then discharges it into the dust collection device of the vacuum cleaner 804 through the air pipe 805.

[0028] A second motor 13 (which can be the same model as the first motor 505) is fixedly inserted through the center of the rear end of the cutting table 1. A second lead screw 14 is fixedly installed at the front end of the output shaft of the second motor 13. The front end of the second lead screw 14 is rotatably connected to the inner wall of the front end of the cutting table 1. A second nut block 15 is threadedly connected to the second lead screw 14. A push plate 16 is fixedly installed on the top of the second nut block 15. The second nut block 15 is located between two adjacent first guide rollers 806. The second motor 13 drives the second lead screw 14 to rotate, which drives the second nut block 15 and the push plate 16 to move along the front and rear direction of the cutting table 1, thereby pushing the cut umbrella fabric pieces that fall on the grid plate 802 forward for easy collection by the operator.

[0029] In actual use, firstly, the umbrella fabric on the feeding roller 6 is pulled out and passes sequentially through the second guide roller 21, the flattening strip 3 on the cutting table 1, the first guide roller 806, and the mesh plate 802, and finally winds onto the winding roller 7. After the material is fed, the first electric push rod 11 is controlled to retract the piston rod, lowering the slider 501 and the flattening strip 3, so that the two flattening strips 3 are pressed tightly against the center of the umbrella fabric. Then, the first motor 505 is started to drive the first lead screw 503 to rotate. The first lead screw 503 drives the two first nut blocks 504 to move in opposite directions, thereby flattening the umbrella fabric. After flattening, the first electric push rod 11 is used to adjust the flattening strip 3 to press down on both sides of the umbrella fabric, which can improve the stability during subsequent cutting and prevent the umbrella fabric from shifting and affecting the cutting accuracy.

[0030] Next, the laser cutting mechanism 2 is started to laser cut the umbrella fabric on the grid plate 802 according to the preset program. During the cutting process, the vacuum cleaner 804 works continuously to suck away the generated smoke and dust through the grid plate 802 and the dust collection box 801.

[0031] After cutting, the first electric push rod 11 and the second electric push rod 18 drive the flattening strip 3, the feeding roller 6 and the winding roller 7 to move upward, so that the cut umbrella fabric is away from the grid plate 802, and the cut waste material can fall onto the grid plate 802 and the first guide roller 806. Then, the second motor 13 is started to drive the second lead screw 14 to rotate. The nut block on the second lead screw 14 drives the push plate 16 to move backward, automatically pushing the waste material from behind the grid plate 802 for easy recycling. Next, the umbrella fabric is cut again according to the above process, so as to realize the continuous cutting of the umbrella fabric.

[0032] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
