Description

Technical Field

[0001] The present invention relates to the technical field of backpack production, and in particular to a laser cutting device for backpack production. Background Art

[0002] The use of laser cutting technology in backpack production has become an efficient and precise processing method in modern manufacturing. The following is a detailed analysis of laser cutting for backpack production:

[0003] 1. Advantages of laser cutting technology

[0004] High precision: Laser cutting can achieve high-precision cutting, with smooth and burr-free cuts, which improves the quality of the finished backpack.

[0005] High efficiency: Laser cutting has a high speed, which can significantly shorten the production cycle and improve production efficiency.

[0006] 2. Application of laser cutting in backpack production

[0007] Fabric Cutting: Backpack fabrics are typically cut using laser cutting machines to ensure precision and efficiency. Laser cutting can process a variety of fabrics, including nylon, polyester, and artificial leather.

[0008] In summary, laser cutting technology for backpack production has significant advantages and broad application prospects. With the continuous advancement of technology and the continuous development of the market, laser cutting technology will play an even more important role in backpack production.

[0009] The utility model patent with prior art announcement number CN214322234U provides a cutting device for backpack production. This technology solves the problem that the cloth becomes less and less when the unwinding roller of the existing laser cutting device unwinds, and when the remaining cloth is too little, the unwinding roller will be higher than the processing table of the laser cutting device, so that the cloth and the processing table no longer fit together, affecting the cutting of the laser cutting device.

[0010] During existing laser cutting techniques, due to the fabric's inherent elasticity, or when the fabric is straightened for cutting, it can bend due to factors such as air flow and cutting vibrations. This bending can cause the cutting path to deviate from the intended path, thus affecting cutting precision and accuracy. Consequently, the cut backpack components may have uneven edges and inaccurate dimensions, affecting the overall quality and appearance of the backpack.

[0011] In summary, the prior art lacks a technology for limiting the position of cutting fabric when cutting fabric for backpacks. Summary of the Invention

[0012] The purpose of the present invention is to solve the shortcomings of the background technology and to propose a laser cutting device for backpack production.

[0013] In order to achieve the above purpose, the technical solution adopted by the present invention is: a laser cutting device for backpack production, including an equipment seat, limit rollers are slidingly provided on both sides of the equipment seat, a placement rack is fixedly provided on one side of the equipment seat, a rotating seat is rotatably provided on the equipment seat, a unloading mechanism is rotatably provided on the rotating seat, an air guide seat is fixedly provided on the equipment seat, an installation mechanism is fixedly provided inside the air guide seat, a cutting template is installed on the installation mechanism, and a cutting mechanism is rotatably provided inside the air guide seat.

[0018] Preferably, an arc-shaped rack is fixedly connected to the inner wall of the bottom end of the equipment base, and the arc-shaped rack is meshed with the gear for transmission.

[0019] Preferably, a filter element is provided in the internal threaded connection of the output end of the air guide seat, a universal joint is provided in the rotation connection inside the air guide seat, a fan blade is fixedly provided at one end of the universal joint, a transmission wheel is fixedly provided at the other end of the universal joint, a motor is fixedly provided in the air guide seat, and a driving wheel is fixedly provided at the output end of the motor.

[0025] 3. By setting up a rotating plate and a blanking mechanism, when the cutting template is moved up and down to reset, the rotating plate will be driven to rotate automatically, thereby separating the cut fabric from the waste. At the same time, under the action of the arc-shaped rack, the belt can drive the fabric pusher to push the cut fabric down. The automated blanking process makes the entire cutting process smoother and more efficient, which helps to improve the overall efficiency of backpack production. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0036] like Figures 1-8The laser cutting device shown in the figure is used for backpack production, including an equipment base 1, with limiting rollers 2 slidingly arranged on both sides of the equipment base 1, a placement rack 3 connected and fixedly arranged on one side of the equipment base 1, a rotating base 4 rotatably connected to the equipment base 1, a blanking mechanism 5 rotatably connected to the rotating base 4, an air guide base 6 connected and fixedly arranged on the equipment base 1, a mounting mechanism 7 fixedly connected to the inside of the air guide base 6, a cutting template 8 is installed on the mounting mechanism 7, and a cutting mechanism 9 is rotatably connected to the inside of the air guide base 6.

[0037] like Figure 3 As shown, a U-shaped frame 201 is rotatably connected to the limiting roller 2. The U-shaped frame 201 is slidably fitted across the equipment base 1. A handle 202 is fixedly attached to one side of the U-shaped frame 201. Multiple springs 203 are fixedly attached to the U-shaped frame 201. The other ends of the springs 203 are fixedly attached to the equipment base 1. Holding the handle 202, the U-shaped frame 201 is lifted upward to allow the fabric to pass through the limiting roller 2. The springs 203 then press the limiting roller 2 against the fabric to limit its position.

[0038] like Figure 3 As shown, a limit rod 301 is provided on the placement rack 3 through a threaded connection.

[0039] like Figure 4 As shown, a worm gear 401 is fixedly mounted on one end of the rotating base 4. A worm 402 is meshed and driven on one side of the worm gear 401. The worm 402 extends through the inner wall of the equipment base 1 and is rotatably connected thereto. A transmission rod 403 is fixedly mounted on the other end of the worm 402. The transmission rod 403 has a transmission groove 404 formed therein. The transmission groove 404 has a spiral structure at the upper end and a linear structure at the lower end. The drive rod 705 slides within the transmission groove 404, thereby rotating the transmission rod 403, which in turn rotates the worm 402, which in turn rotates the rotating base 4 connected to the worm gear 401.

[0040] like Figure 5 As shown, the unloading mechanism 5 includes a belt 501, to which a fabric pusher 502 is fixedly mounted. Pulleys 503 are provided at both ends of the belt 501 for friction transmission. The pulleys 503 are rotatably connected to the rotating base 4. One end of one of the pulleys 503 extends through the inner wall of the rotating base 4 via a pin and is fixedly connected to a gear 504. When the gear 504 engages the arc-shaped rack 101, it drives the gear 504 connected to the gear 504 to rotate, thereby driving the fabric pusher 502 on the belt 501 to rotate, pushing the cut fabric off the rotating base 4.

[0041] like Figure 3 As shown, an arc-shaped rack 101 is fixedly connected to the inner wall of the bottom end of the equipment base 1, and the arc-shaped rack 101 is meshed with the gear 504 for transmission.

[0042] like Figure 6 As shown, the output end of the air guide seat 6 is internally threaded and connected to a filter element 601. A universal joint 602 is rotatably connected to the air guide seat 6. One end of the universal joint 602 is fixedly connected to a fan blade 603. The other end of the universal joint 602 is fixedly connected to a transmission wheel 604. A motor 605 is fixedly connected to the air guide seat 6, and the output end of the motor 605 is fixedly connected to a driving wheel 606. When the rotating frame 901 rotates, it drives the connected transmission gear plate 905 to rotate. At this time, the transmission gear plate 905 drives the transmission wheel 604 to rotate, and the transmission wheel 604 drives the fan blade 603 connected to the universal joint 602 to rotate, sucking the smoke and dust generated by laser cutting into the air guide seat 6 and filtering it through the filter element 601.

[0043] like Figure 7 As shown, the cutting mechanism 9 includes a rotating frame 901, which is rotatably connected to the air guide seat 6, and an electric push rod 902 is fixedly connected to the other end of the rotating frame 901. The other end of the electric push rod 902 is installed with a laser cutter 903. A driven wheel 904 is fixedly connected to the rotating frame 901, and the driven wheel 904 is meshed with the driving wheel 606 for transmission. A transmission gear plate 905 is fixedly connected to the rotating frame 901, and the transmission gear plate 905 is meshed with the driving wheel 604 for transmission. The motor 605 drives the driving wheel 606 to rotate, and the driving wheel 606 drives the rotating frame 901 connected to the driven wheel 904 to rotate. At this time, the electric push rod 902 drives the laser cutter 903 to cut along the edge of the cutting template 8.

[0044] like Figure 8 As shown, the mounting mechanism 7 includes a hydraulic rod 701, which is fixedly connected to the air guide seat 6 through the hydraulic rod 701. The bottom end of the hydraulic rod 701 is fixedly connected to a mounting seat 702. Two mounting blocks 703 are slidably fitted in the mounting seat 702. A tension spring 704 is fixedly connected between the mounting blocks 703 and the mounting seat 702. A mounting sleeve 801 is fixedly connected to the cutting template 8. The mounting sleeve 801 is movably connected to the mounting blocks 703 and the mounting seat 702. A driving rod 705 is fixedly connected to one side of the mounting seat 702. The other end of the driving rod 705 is slidably fitted with the inner wall of the transmission groove 404. When the mounting sleeve 801 on the cutting template 8 is inserted into the mounting seat 702, the tension spring 704 will drive the mounting blocks 703 to engage with the mounting sleeve 801.

[0045] Working principle: When the fabric for backpack production needs to be cut, first replace the corresponding cutting template 8 according to the shape of the cutting part, insert the mounting sleeve 801 on the cutting template 8 into the mounting seat 702, and then the tension spring 704 will drive the mounting block 703 to be clamped and fixed with the mounting sleeve 801;

[0046] Then place the fabric roll on the placement rack 3, insert the limiting rod 301 into the center of the fabric roll and threadedly connect it to the placement rack 3 to limit the fabric roll, then pull out one end of the fabric and hold the handle 202, lift the U-shaped rack 201, so that the fabric passes through the limiting roller 2, and then the spring 203 will make the limiting roller 2 press on the fabric to limit it, and then continue to pull the fabric to place it on the rotating seat 4, and the other end passes through another limiting roller 2;

[0047] Then, the hydraulic rod 701 is used to drive the cutting template 8 on the mounting seat 702 to move downward and press on the cloth. Then, the equipment is controlled so that the motor 605 drives the driving wheel 606 to rotate, so that the driving wheel 606 drives the rotating frame 901 connected to the driven wheel 904 to rotate. At this time, the electric push rod 902 is used to drive the laser cutter 903 to cut along the edge of the cutting template 8;

[0048] At the same time, when the rotating frame 901 rotates, it drives the connected transmission gear plate 905 to rotate. At this time, the transmission gear plate 905 drives the transmission wheel 604 to rotate, so that the transmission wheel 604 drives the fan blade 603 connected to the universal joint 602 to rotate, sucking the smoke and dust generated by laser cutting into the air guide seat 6 and filtering it through the filter element 601;

[0049] After cutting is completed, the cutting template 8 is driven to move up and reset. At this time, the driving rod 705 on the mounting seat 702 will slide in the transmission groove 404, thereby driving the transmission rod 403 to rotate, so that the transmission rod 403 drives the worm 402 to rotate, so that the worm 402 drives the rotating seat 4 connected to the worm wheel 401 to rotate, and then when the gear 504 is engaged with the arc-shaped rack 101, it drives the gear 504 connected to the gear 504 to rotate, thereby driving the cloth pusher 502 on the belt 501 to rotate, pushing the cut cloth on the rotating seat 4 down, and completing the material unloading.
