Description

Technical Field

[0001] This invention relates to the field of laser cutting device technology, and specifically to a laser cutting device for backpack production. Background Technology

[0002] As is well known, laser cutting devices for backpack production are a type of equipment specifically designed for cutting backpack fabrics. Leveraging the characteristics of laser technology, they can achieve high-precision and high-efficiency cutting operations. In recent years, as consumers' comprehensive requirements for the practicality and aesthetics of backpacks have continued to increase, fur materials, due to their combination of texture and decorative effects, have been widely used in the main body materials and decorative parts of backpacks. To meet the demand for precise cutting of fur materials, we propose a laser cutting device for backpack production.

[0040] It should be further explained that an insertion pressing assembly is installed inside the lifting frame 5. The insertion pressing assembly includes a mounting frame 10, a support frame 11, a synchronization frame 12, an electric drive rod 13, and a limiting frame 14.

Each clamping wire 18 is equipped with a hook head 20, which is matched with multiple clamping components. The clamping components include a first wedge frame 21 and a second wedge frame 22. Both the first wedge frame 21 and the second wedge frame 22 are fixedly connected to a rotating shaft 23. The guide sleeve 16 has two rotating holes 24, and the two rotating shafts 23 are rotatably connected to the two rotating holes 24.

The hook head 20 is provided with a tail rod section 30, and the tail rod section 30 is provided with a wire insertion groove 31. The clamping wire 18 is fixed in the wire insertion groove 31 by a clamping bolt. The limiting hole 19 is provided with an alignment groove 32 that matches the tail rod section 30. The opposite side of the first wedge frame 21 and the second wedge frame 22 is provided with a semi-through groove 33 that matches the tail rod section 30. Multiple support wheel frames 38 are fixedly connected to the support frame 11. Each of the multiple support wheel frames 38 is rotatably connected to a support wheel 39. Each of the multiple support wheels 39 matches a multiple clamping wire 18. Each of the multiple support wheel frames 38 is rotatably connected to a support wheel 39. A blocking and limiting wheel 40 is connected to the pressing wire 18. Through the design of the insertion pressing component, it can cooperate with the fur material being cut to form an auxiliary pressing and positioning. The insertion pressing component uses the pressing wire 18 for pressing operation, which has the advantage of small contact area. It can accurately complete the cutting and positioning action relative to the fur material, minimize the crushing phenomenon on the fur surface, and further reduce the adverse effects of the cutting operation on the fur surface.

[0042] In this embodiment, the electric drive rod 13, the electric adjustment rod 42, the first servo motor 44, and the second servo motor 45 are all commercially available conventional devices known to those skilled in the art. In this invention, we are simply using them without making any improvements to their structure or function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. Therefore, we will not elaborate on them here.

[0043] In summary, the working principle of this laser cutting device for backpack production is as follows: First, the device is installed at the designated location. Simultaneously, the electrical connections of the electric drive rod 13, electric adjustment rod 42, first servo motor 44, and second servo motor 45 are completed. An electrostatic applicator is electrically connected to the electrostatic conductor plate 6. A laser generator is installed on the laser cutting head 3. After installation, no-load operation and debugging are performed. During debugging, the drive assembly is started through the control system connected to the control circuit. This verifies whether the lifting platform 41 moves smoothly along the mounting cylinder 2 under the drive of the electric adjustment rod 42, whether the rotation accuracy of the rotating frame 43 under the drive of the first servo motor 44 meets the standard, and whether the translational movement of the sliding seat 47 under the cooperation of the second servo motor 45 and the lead screw 46 is stable. This ensures that the laser cutting head 3 can achieve multi-dimensional flexible adjustment through the drive assembly to meet the movement requirements of different cutting paths. The electrostatic adsorption structure is also debugged simultaneously, and the device is then started. The electric lifting rod 7 verifies the sliding and lifting stability of the lifting frame 5 along the equipment base 1, checks the linkage consistency of the synchronous frame 12 in the insertion pressing assembly under the drive of the electric drive rod 13, and the reset flexibility of the clamping frame 35 in the linkage positioning assembly under the action of the reset spring 36, ensuring that there is no jamming or interference in each mechanical structure. After debugging, first control the electric drive rod 13 to drive the guide sleeve 16 to move from directly above the glass worktable 4 to form a pull-out. By controlling the electric lifting rod 7 to drive the lifting frame 5 to slide upward along the equipment base 1, the electrostatic conductor plate 6 rises synchronously with the lifting frame 5, thereby giving the glass worktable 4 a higher working space, which facilitates the flat placement of fur materials. After adjustment, the staff lays the fur material to be cut flat on the glass worktable 4, ensuring that the fur side of the material is facing up and the back side to be cut is facing down and in contact with the glass worktable 4. At the same time, according to the positioning requirements of the cutting pattern, the material placement position is initially adjusted to complete the preliminary preparation work.

[0044] Next, the positioning and fixing process begins. First, the pre-positioning procedure is initiated. The control system issues a command to drive the electric lifting rod 7 to slide the lifting frame 5 downwards along the equipment base 1, causing the insertion and pressing components on the lifting frame 5 to move downwards synchronously. During this process, the guide sleeve 16 falls synchronously, and the cutting push hook plate 37 fixed on the guide sleeve 16 falls synchronously with it. When the guide sleeve 16 falls to the area corresponding to the fur material, the electric lifting rod 7 is controlled to enter a parking state. The falling height of the guide sleeve 16 is ideally such that it enters the interference zone relative to the fur surface of the fur material, while forming a close fit with the top of the fur surface. Then, the... The electric drive rod 13 extends, causing the synchronous frame 12 to move horizontally. The synchronous frame 12 drives all the guide sleeves 16 to slide horizontally along the insertion strip 15 and enter directly above the glass worktable 4. The cutting push hook plate 37 moves horizontally synchronously with the guide sleeves 16 it is connected to. When the cutting push hook plate 37 moves to the corresponding position with the clamping frame 35 in the linkage positioning assembly, the cutting push hook plate 37 contacts the end of the clamping frame 35 and continuously applies a downward pushing force, forcing the clamping frame 35 to rotate around the rotation connection point of the fixed ear seat 34. The return spring 36 is elastically compressed, and the clamping frame 35 gradually... As the material approaches the glass worktable 4, the clamping end of the final clamping frame 35 contacts the edge area of ​​the material and forms a pre-clamping force, achieving pre-positioning of the material and preventing overall displacement of the material during the subsequent cutting of the pressing components. During the horizontal movement of the guide sleeve 16, the corresponding first wedge frame 21 and second wedge frame 22 move accordingly. Utilizing the cutting and pressing slope 48 and the edge cutting and brushing surface 49 provided by both, the material smoothly cuts into the gaps in the fur surface. During this process, the edge cutting and brushing surface 49 assists in brushing and guiding the fur, reducing the likelihood of the fur being forcibly pressed down or broken. Simultaneously, as... As the guide sleeve 16 continues to move, the cutting tip 28 on the hook head 20 contacts the cutting slope 29 on the first wedge frame 21 and the second wedge frame 22 and generates relative compression, forcing the first wedge frame 21 and the second wedge frame 22 to rotate around the connecting shaft 23, causing the top spring 25 to undergo elastic deformation. When the tail rod section 30 of the hook head 20 moves to the position corresponding to the semi-through groove 33 of the first wedge frame 21 and the second wedge frame 22, the reset elastic force of the top spring 25 drives the first wedge frame 21 and the second wedge frame 22 to reset, so that the semi-through groove 33 and the tail rod section 30 are precisely fitted, thereby realizing the snap-fit ​​fixation between the hook head 20 and the clamp.

[0045] Next, the guide sleeve 16 is controlled to move horizontally away from the top of the glass worktable 4, so that the clamping wire 18 enters the top of the glass worktable 4. Through the action of the cone spring 17 at the bottom of the support frame 11, the clamping wire 18 can always be kept in a taut state. When the guide sleeve 16 completely escapes from the glass worktable 4 again, the clamping wire 18 will cross over the fur material to form an auxiliary clamping effect on the fur material. If necessary, the electric lifting rod 7 is activated to control the lifting frame 5 to move further down, thereby causing the clamping wire 18 to form a further relative clamping effect with the fur material. Because the clamping wire 18 is relatively thin, the clamping wire 1... 8. The contact area with the fur material is extremely small, minimizing pressure damage to the fur surface. After clamping and positioning, the electrostatic-assisted cutting process begins. The control system activates the electrostatic applicator. Under the insulating protection of the insulating ring 9, the electrostatic conductor plate 6 generates a stable electrostatic field. Through electrostatic adsorption, it generates a directional adsorption force on the fur surface and hair of the fur material, causing the hair to remain upright. This further increases the distance between the fur surface and the cutting area, preventing laser damage to the fur surface during the cutting process. The control system issues motion commands to the drive assembly according to the preset cutting pattern parameters, and the electric adjusting rod 42 drives... The lifting platform 41 moves up and down along the mounting cylinder 2, adjusting the distance between the laser cutting head 3 and the bottom of the glass worktable 4 to ensure that the laser focus is accurately aligned with the back cutting area of ​​the fur material. The first servo motor 44 drives the rotating frame 43 to rotate, thereby adjusting the circumferential angle of the laser cutting head 3 to adapt to the curved cutting path. The second servo motor 45 drives the lead screw 46 to rotate, and through the threaded engagement between the lead screw 46 and the sliding seat 47, the sliding seat 47 moves along the rotating frame 43 to achieve linear motion adjustment of the laser cutting head 3. Under the coordinated action of the drive components, the laser cutting head 3 moves along the glass worktable according to the preset path. 4. Moving smoothly downwards, the laser generated by the laser generator is emitted through the laser cutting head 3. After penetrating the transparent glass worktable 4, the laser beam is precisely applied to the back of the fur material. The back-cutting process is used to complete the cutting operation, effectively avoiding damage such as burning or charring of the fur caused by the laser acting on the fur surface. During the cutting process, the electrostatic conductor plate 6 continuously generates electrostatic adsorption force to ensure that the fur always remains upright. The clamping wire 18 inserted into the pressing component and the clamping piece continuously ensure the stable positioning of the material cutting area, reducing the displacement of the fur material during the cutting process and the lifting phenomenon caused by electrostatic adsorption.

[0046] After the laser cutting head 3 completes the preset cutting path, the control system first shuts down the laser generator and then the electrostatic applicator, stopping the laser cutting operation. The electrostatic adsorption effect weakens until it disappears. Then, the electric lifting rod 7 drives the lifting frame 5 to slide upward along the equipment base 1, causing the entire insertion pressing assembly to detach from the fur material, completing the release of the pressing positioning. After the cutting push hook plate 37 rises with the guide sleeve 16, the pushing force on the pressing frame 35 gradually disappears. Under its own elastic force, the return spring 36 drives the pressing frame 35 to rotate in the opposite direction to reset, releasing the pre-pressing on the edge of the fur material. Subsequently, the electric drive rod 13 is activated. The telescopic rod of the electric drive rod 13 extends, causing the synchronous frame 12 to continue to move backward. The guide sleeve 16 continues to slide backward along the insertion strip 15. During the continuous horizontal movement of the synchronous frame 12, the push head 27 on the insertion strip 15 contacts the backing rod 26 of the first wedge frame 21 and the second wedge frame 22 and applies a pushing force, forcing The two rotate around the connecting shaft 23 and open again, releasing the engagement with the hook head 20. Under the action of the cone spring 17, the clamping wire 18 moves back to its original position for the next use. After that, the workers can safely remove the finished fur products and scraps, clean the surface of the glass workbench 4, and remove any remaining hair and debris. Then, the next batch of fur material cutting process can begin. Throughout the operation, the various structures work together to achieve precise cutting while minimizing damage to the fur surface of the fur material, ensuring the quality of the fur pieces used in backpack production. The activation time of the electrostatic conductor plate 6 can be flexibly selected. It can be used either when the clamping wire 18 is inserted into the fur surface or after the clamping wire 18 has clamped the fur material. When the clamping wire 18 is inserted into the fur surface, the corresponding hair is in an upright position, which facilitates the smooth passage of the clamping wire 18 relative to the hair.
