Description

Technical Field

[0001] This application relates to the field of cutting machine technology, and in particular to a multi-functional cutting machine. Background Technology

[0002] In industries such as textiles and garment processing, fabric cutting is a crucial step. Traditional fabric cutting equipment often uses a single cutting method, which cannot adapt to the cutting needs of different fabric materials. This leads to low production efficiency and inconsistent product quality.

[0003] Chinese patent CN222758604U discloses a multi-functional cutting machine, which includes a conveying device. Above the conveying device, along the transport direction of the fabric, are sequentially arranged a first pressing device, a hard cutting device, an electric flying knife cutting device, a second pressing device, an electric die-cutting device, and a heating wire device. The blades of the hard cutting device and the electric flying knife cutting device are both arranged parallel to the fabric feeding direction, while the blade of the electric die-cutting device is arranged laterally. Both the hard cutting device and the electric flying knife cutting device are connected to a driving cylinder for driving the blades to move up and down. The machine also includes a fabric receiving device. This invention allows for the selection of a suitable cutting method based on the type of fabric, thereby greatly improving the flexibility and adaptability of cutting, and ensuring product quality and production efficiency.

[0004] The existing multi-functional cutting machines have a low degree of integration in the cutting section, require various types of cutting devices to be arranged continuously, occupy a large area, and have high land costs, which is not conducive to the large-scale production of fabrics. Utility Model Content

[0005] To address the problems existing in the prior art, this application provides a multi-functional cutting machine.

[0006] The multi-functional cutting machine provided in this application adopts the following technical solution: A multi-functional cutting machine includes a fabric conveying device and a cutting mechanism mounted on the conveying device. The cutting mechanism is slidably mounted along the length of the frame under the drive of a power mechanism. The cutting mechanism houses a switchable toothed blade cutting device, an electric flying knife cutting device, and a laser cutting device. The cutting mechanism includes a cutting frame and a rotating disk that is lifted and installed within the cutting frame. A cutting base is detachably mounted on the bottom of the cutting frame. The toothed blade cutting device includes a bottom pressure roller and a discontinuous toothed blade. The discontinuous toothed blade, the electric flying knife cutting device, and the laser cutting device are mounted in mounting slots within the rotating disk, and these mounting slots are arranged in a circumferential array on the rotating disk. The bottom pressure roller is mounted on the cutting base and driven by a servo motor. The rotating disk is lifted and installed on the cutting frame via its mounting seat. A hydraulic cylinder is provided on the top of the cutting frame to drive the lifting and lowering of the mounting seat.

[0007] By adopting the above technical solution, the conveying device first transports the fabric to the area below the cutting mechanism. Depending on the fabric material, the rotating disc adjusts the corresponding type of cutting device to the bottom. Then, the hydraulic cylinder at the top of the cutting frame drives the rotating disc's mounting base to descend, bringing the corresponding cutting device closer to the fabric. If a toothed blade cutting device is used, the bottom pressure roller and the discontinuous cutting toothed blade press the fabric firmly. A servo motor drives the pressure roller to rotate, simultaneously rotating the discontinuous cutting toothed blade to cut. The discontinuous cutting toothed blade is a corrugated toothed blade, continuously cutting the fabric with its discontinuous cutting edge. If an electric flying knife cutting device is used, the electric flying knife rotates at high speed, coordinating with the movement of the rotating disc to cut the fabric. If a laser cutting device is selected, the laser emits a laser beam, which is focused onto the fabric surface through the optical path system, causing the fabric to reach its melting or boiling point. Simultaneously, high-pressure gas blows away the molten or vaporized portion, and the cutting is completed as the laser beam moves relative to the fabric. After cutting, the rotating disc rises under the action of the hydraulic cylinder, allowing switching to other cutting devices or allowing the conveying device to continue transporting fabric for the next round of cutting.

[0008] Preferably, a longitudinal through mounting hole is provided inside the cutting frame, a guide groove is provided on the inner side of the mounting hole, a guide protrusion adapted to the guide groove is provided on the outer side of the mounting base, and an adjustable rotating disk is installed on the inner side of the mounting base.

[0009] Preferably, the length of the mounting base is greater than the length of the mounting hole. An adjusting roller is installed on the side of the mounting base away from the frame outside the mounting hole. One end of the adjusting roller passes through the mounting base, and the other end is equipped with a rotating handle. A rotating disk is fixed to the part of the adjusting roller that passes through the mounting base. The adjusting roller can drive the rotating disk to rotate to realize the switching of the cutting device.

[0010] Preferably, the end of the adjusting roller near the handle is a threaded part, and the other end is a support part, and a locking nut that can lock the rotating disk in the cutting frame is fitted on the threaded part.

[0011] Preferably, the rotating disk has a circumferential array of limiting protrusions, which are located on both sides of the rotating disk, and the limiting protrusions are adapted to the limiting slots on the inner side of the mounting base.

[0012] Preferably, the adjusting roller is a hollow roller body, and a support roller is fixedly installed at one end of the mounting base away from the adjusting roller. The outer diameter of the support roller is adapted to the inner diameter of the adjusting roller, and the other end of the support roller is fixedly connected to the inner wall of the through hole through the mounting base of the adjusting roller. The adjusting roller is provided with an adjusting hole for the adjusting roller to move when adjusting the cutting device.

[0013] Preferably, the adjustment hole is a T-shaped structure, and the top two ends of the T-shaped structure are provided with upwardly extending positioning holes.

[0014] By adopting the above technical solution, when switching the cutting device, first loosen the locking nut on the threaded part of the adjusting roller to release the locking state of the rotating disk. Since the default state is that the toothed blade cutting device is in the bottom working position, when it is necessary to adjust to the electric flying knife cutting device or the laser cutting device, the operator pulls the adjusting roller to move the rotating disk from one side wall to the other side wall inside the mounting base. During this process, the connecting block between the top of the support roller and the top surface of the through hole in the mounting base moves along the vertical part of the T-shaped adjusting hole. Then, rotate the rotating handle at one end of the adjusting roller. During this process, the connecting block moves along the horizontal part of the T-shaped adjusting hole. Since the adjusting roller is fixed to the rotating disk, the rotation of the adjusting roller drives the rotating disk to rotate. At the same time, the guide protrusion on the outside of the mounting base cooperates with the guide groove on the inside of the cutting frame mounting hole to ensure that the mounting base moves smoothly in the longitudinal direction during the rotating disk switching process, and the adjusting roller rotates stably under the support of the support roller. As the rotating disk rotates, the circumferential array of limiting protrusions on both sides separates from the limiting slots on the inner side of the mounting base. Once adjustment is complete, the limiting protrusions engage with the limiting slots, placing the rotating disk in a precise switching and positioning state. Furthermore, the T-shaped adjustment holes on the adjusting roller provide movement space for adjusting the cutting device. The positioning holes at both ends of the T-shaped structure can be used to engage the limiting protrusions on the rotating disk with the limiting slots on the inner side of the mounting base after the rotating disk has rotated to the corresponding position. After switching the cutting device, tighten the locking nut to securely lock the rotating disk within the cutting frame. Then, the corresponding cutting device can be started to cut the fabric on the conveyor.

[0015] Preferably, the power mechanism includes a lead screw that runs through the cutting frame along the length of the frame, with bearing seats and an adjusting motor at both ends of the lead screw, and a wire sleeve adapted to the lead screw is provided inside the cutting frame.

[0016] By adopting the above technical solution, when it is necessary to drive the cutting mechanism to move along the length of the frame, the motor is started, driving the lead screw to rotate. Since both ends of the lead screw are supported by bearing seats, the stability of the rotation can be ensured. At this time, the thread sleeve that is adapted to the lead screw inside the cutting frame will move linearly along the lead screw under the action of the lead screw rotation. Because the thread sleeve is fixed inside the cutting frame, it drives the entire cutting frame and cutting mechanism to slide together along the length of the frame, so that the cutting mechanism can move to the appropriate position to perform cutting operations according to the fabric cutting requirements.

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. This application integrates a toothed blade cutting device, an electric flying knife cutting device, and a laser cutting device into a switchable rotating disk, and with the sliding design and lifting structure of the cutting mechanism along the length of the frame, it achieves efficient integration and flexible switching of multiple cutting methods; 2. The mounting slots of the circumferential array on the rotating disk of this application can quickly switch between different cutting devices. The bottom pressure roller and servo motor drive ensure the stability of the fabric during cutting. The hydraulic cylinder drives the mounting seat to lift and lower to adapt to the cutting requirements of different fabric thicknesses. The screw drive power mechanism enables the cutting mechanism to slide along the frame to achieve full-width cutting of the fabric.

[0018] 3. The design of this application significantly improves the integration of the cutting device, reduces the equipment footprint and land cost, and at the same time, through the flexible switching of multiple cutting methods, it can adapt to the cutting needs of different fabric materials, effectively improving cutting efficiency and product quality stability, and providing strong support for the large-scale production of fabrics.

[0022] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0023] This application discloses a multi-functional cutting machine.

[0024] Reference Figures 1-6A multi-functional cutting machine includes a conveying device 1 for conveying fabric and a cutting mechanism 2 installed on the conveying device 1. The cutting mechanism 2 is slidably installed along the length of the frame 4 under the drive of the power mechanism 3. The cutting mechanism 2 is equipped with a switchable toothed blade cutting device 5, an electric flying knife cutting device 6, and a laser cutting device 7. The cutting mechanism 2 includes a cutting frame 21 and a rotating disk 22 that is lifted and installed in the cutting frame 21. A cutting base 23 is detachably installed at the bottom of the cutting frame 21. The toothed blade cutting device 5 includes a bottom pressure roller 51 and a discontinuous cutting tooth 52. The discontinuous cutting tooth 52, the electric flying knife cutting device 6, and the laser cutting device 7 are installed in the mounting slots 221 within the rotating disk 22, and the mounting slots 221 are arranged in a circumferential array on the rotating disk 22. The bottom pressure roller 51 is mounted on the cutting base 23 and driven by a servo motor 231. The rotating disk 22 can be raised and lowered on the cutting frame 21 via its mounting seat 24. The top of the cutting frame 21 is equipped with a hydraulic cylinder 211 that drives the mounting seat 24 to rise and fall. The conveying device 1 first conveys the fabric to the area below the cutting mechanism 2. According to the fabric material, the rotating disk 22 is rotated to adjust the corresponding type of cutting device to the bottom. Then, the hydraulic cylinder 211 at the top of the cutting frame 21 drives the mounting seat 24 of the rotating disk 22 to descend, bringing the corresponding cutting device inside the rotating disk 22 closer to the fabric. If the toothed blade cutting device 5 is used, the bottom pressure roller 51 and the discontinuous cutting edge toothed blade 52 press the fabric tightly. The servo motor 231 drives the pressure roller to rotate, while simultaneously driving the discontinuous cutting edge toothed blade 52 to rotate and cut. The discontinuous cutting edge toothed blade 52 is a corrugated toothed blade, which continuously cuts the fabric using its discontinuous cutting edge. If the electric flying knife cutting device 6 is used, the electric flying knife rotates at high speed, cooperating with the movement of the rotating disk 22 to cut the fabric. If the laser cutting device 7 is selected, the laser emits a laser beam, which is focused on the surface of the fabric through the optical path system, causing the fabric to reach its melting or boiling point. At the same time, high-pressure gas blows away the molten or vaporized parts, and the cutting is completed as the laser beam moves relative to the fabric. After the cutting is completed, the rotating disk 22 is raised under the action of the hydraulic cylinder 211, which can be used to switch to other cutting devices or allow the conveyor device 1 to continue conveying the fabric for the next round of cutting.

[0025] Reference Figures 1-6A longitudinally penetrating mounting hole 212 is provided inside the cutting frame 21. A guide groove 213 is provided on the inner side of the mounting hole 212. A guide protrusion 241 adapted to the guide groove 213 is provided on the outer side of the mounting base 24. An adjustable rotating disk 22 is installed on the inner side of the mounting base 24. The length of the mounting base 24 is greater than the length of the mounting hole 212. An adjusting roller 25 is installed on the side of the mounting base 24 outside the mounting hole 212 away from the frame 4. One end of the adjusting roller 25 passes through the mounting base 24, and a rotating handle 251 is installed on the other end. The portion of the adjusting roller 25 that passes through the mounting base 24 is fixed with the rotating disk 22. The adjusting roller 25 can drive the rotating disk 22 to rotate to switch the cutting device. The end of the adjusting roller 25 near the handle is a threaded part 252, and the other end is a support part 253. A locking nut 254 is fitted on the threaded part 252 to lock the rotating disk 22 in the cutting frame 21. The rotating disk 22 has a circumferential array of limiting protrusions 222, which are located on both sides of the rotating disk 22. These limiting protrusions 222 are adapted to the limiting grooves 242 on the inner side of the mounting base 24. The adjusting roller 25 is a hollow roller body. A support roller 243 is fixedly installed at one end of the mounting base 24 away from the adjusting roller 25. The outer diameter of the support roller 243 is adapted to the inner diameter of the adjusting roller 25, and the other end of the support roller 243 is fixedly connected to the inner wall of the through hole in the mounting base 24 through which the adjusting roller 25 passes. The adjusting roller 25 has an adjusting hole 255 for moving when adjusting the cutting device. The adjusting hole 255 has a T-shaped structure, and the top two ends of the T-shaped structure have upwardly extending positioning holes 256. When switching the cutting device, first loosen the locking nut 254 on the threaded part 252 of the adjusting roller 25 to release the locking state of the rotating disk 22. Because the default state is that the toothed blade cutting device 5 is in the bottom working position, when it is necessary to adjust to the electric flying knife cutting device 6 or the laser cutting device 7, the operator pulls the adjusting roller 25 to move the rotating disk from one side wall to the other side wall inside the mounting base 24. During this process, the connecting block between the top of the support roller 243 and the top surface of the through hole in the mounting base 24 moves along the vertical part of the T-shaped adjusting hole 255. Then, the rotating handle 251 at one end of the adjusting roller 25 is rotated. During this process, the connecting block moves along the horizontal part of the T-shaped adjusting hole 255. Since the adjusting roller 25 is fixed to the rotating disk 22, the rotation of the adjusting roller 25 drives the rotating disk 22 to rotate. At the same time, the guide protrusion 241 on the outside of the mounting base 24 cooperates with the guide groove 213 on the inside of the mounting hole 212 of the cutting frame 21 to ensure that the mounting base 24 moves smoothly in the longitudinal direction during the switching of the rotating disk 22, and the adjusting roller 25 rotates stably under the support of the support roller 243. When the rotating disk 22 rotates, the limiting protrusions 222 of the circumferential array on both sides of the disk separate from the limiting slots 242 on the inner side of the mounting base 24. When the adjustment is completed, the limiting protrusions 222 are engaged in the limiting slots 242, and the rotating disk 22 is in an accurate switching positioning state.Furthermore, the T-shaped adjustment holes 255 on the adjusting roller 25 provide movement space for the adjusting roller 25 when adjusting the cutting device. The positioning holes 256 at both ends of the top of the T-shaped structure can be used to engage the limiting protrusions 222 on the rotating disk 22 with the limiting slots 242 inside the mounting base 24 after the rotating disk 22 is rotated to the corresponding position. After switching the cutting device, tighten the locking nut 254 to securely lock the rotating disk 22 inside the cutting frame 21. Then, the corresponding cutting device can be started to cut the fabric on the conveying device 1.

[0026] Reference Figure 1 and Figure 2 The power mechanism 3 includes a lead screw 31 that runs through the cutting frame 21 along the length of the frame 4. Bearing seats 32 and an adjusting motor 33 are respectively located at both ends of the lead screw 31. A sleeve adapted to the lead screw 31 is installed inside the cutting frame 21. When it is necessary to drive the cutting mechanism 2 to move along the length of the frame 4, the adjusting motor 33 starts, driving the lead screw 31 to rotate. Since both ends of the lead screw 31 are supported by bearing seats 32, the stability of the rotation is ensured. At this time, the sleeve adapted to the lead screw 31 inside the cutting frame 21 will move linearly along the lead screw 31 under the action of its rotation. Because the sleeve is fixed inside the cutting frame 21, it drives the entire cutting frame 21 and the cutting mechanism 2 to slide together along the length of the frame 4, thereby enabling the cutting mechanism 2 to move to a suitable position for cutting operations according to the fabric cutting requirements.

[0027] Working principle: The conveying device 1 is responsible for conveying the fabric. The lead screw 31 in the power mechanism 3 rotates under the drive of the adjusting motor 33, and drives the cutting mechanism 2 to slide along the length of the frame 4 through the thread sleeve, realizing lateral movement and cutting. Inside the cutting mechanism 2, the rotating disk 22 is raised and lowered by the hydraulic cylinder 211 driven by the mounting base 24, which can be close to or away from the fabric. The toothed knife cutting device 5 with corrugated toothed blades, the electric flying knife cutting device 6, and the laser cutting device 7 are respectively installed in the circumferential array of mounting slots 221 on the rotating disk 22. The bottom pressure roller 51 is installed on the cutting base 23 and driven by the servo motor 231 to press the fabric. When it is necessary to switch the cutting mode, the rotating handle 251 of the rotating adjusting roller 25 is rotated to switch the cutting device. In this way, different cutting devices can be switched according to the fabric material to complete the corresponding cutting operation and realize multi-functional cutting.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
