Description

Technical Field

[0001] This invention relates to the fields of automated intelligent machine tools and textile and garment manufacturing, and in particular to a cutting head with a guide air and oil groove for a cutting blade that corrects deviation. Background Technology

[0002] The cutting head is one of the main structures of a digital cutting machine. Its primary function is to control the cutting blades positioned at its location during the cutting process, enabling them to move vertically and vertically and rotate 360 ​​degrees to cut textiles. For example, patent number CN201310050208.X describes a blade correction device for a cutting head, which belongs to the cutting machine field. This invention includes a pressure plate, a blade holder, a guide wheel frame, pressure rollers, and a position sensor on an elastic arm. The pressure plate is equipped with a guide wheel frame, which houses a pressure roller and a rear pressure roller. The guide wheel frame is connected to the pressure plate via an elastic arm, and the guide wheel frame, elastic arm, and pressure plate are integrated. The blade holder includes a pressure block, a fixed blade core, a rotating core, and an elastic connecting rod. The rotating core is movably positioned between the pressure block and the fixed blade core and is connected to the elastic connecting rod. This invention solves the problem of blade torsion caused by the fabric squeezing the cutting blade during cutting by using a blade correction device, preventing blade breakage, reducing deviation, adjusting gap in time, and ensuring product quality. Although the prior art also emphasizes the protection of the cutting blade, it still uses a single head structure for correction displacement, and it cannot completely solve the problem of the blade being blocked or entangled by threads in the correction device. Summary of the Invention

[0003] The purpose of this invention is to provide a rotating structure for a digital cutting blade, a cutting head with an air and oil guide groove, a cutting blade equipped with a guide for lubricating oil and air blowing, a cutting blade disc in the form of a male and female blade holder, both of which can rotate for correction, and a female blade disc with a beveled cutting head for cutting off threads and other debris entangled on the main cutting blade, preventing sticking and keeping the cutting blade clean. The female blade disc and the beveled cutting head are equipped with a lubricant introduction structure to maximize the protection of the female blade disc, the beveled cutting head, and the cutting blade in the active state.

[0004] To achieve the above objectives, the technical solution of the present invention is: a correction cutting head with an air and oil guide groove, comprising a correction master disc and a cutting head, wherein: a correction sub-disc is provided on the top of the correction master disc or in the disc groove; the cutting head includes a rotating frame at the top, a correction sub-disc rotating motor is provided at the bottom of the rotating frame, and a rotating drive rod is also provided parallel to the side of the correction sub-disc rotating motor, the bottom of the rotating drive rod is connected to the rotating rod of the correction master disc or directly inserted into the rotating rod hole; the correction sub-disc rotating motor rotates the rotating frame, thereby driving the rotation of the correction master disc by the rotating rod, or directly pushing the correction master disc or the correction master disc and the correction sub-disc to rotate;

[0005] Below the rotating frame is a cutting blade holder with a lifting rod. The cutting blade holder includes a blade head holder and a cutting blade. The blade head holder clamps the cutting blade with its own ventilation clamp. The back of the cutting blade is vertically provided with an oil-gas passage from top to bottom. Above the ventilation clamp is a gas-liquid separator. The gas-liquid separator extends into a machine head blade air supply pipe and a machine head blade liquid supply pipe. The machine head blade air supply pipe and machine head blade liquid supply pipe are connected to a gas-liquid valve. The gas-liquid valve outputs lubricating fluid or gas to the oil-gas passage.

[0006] The correction master disk is provided on top or in the disk groove. The correction sub-disk includes a sub-disk module, a sub-disk rotating ring, an electric slip ring, and a driver. The electric slip ring is arranged around the sub-disk rotating ring. The sub-disk module is arranged in the ring hole or on the sub-disk rotating ring itself. The driver is energized to rotate the sub-disk rotating ring. The driver is also provided with a sensing spring to sense and collect the rotation or stationary action signals of the sub-disk rotating ring and the electric slip ring. The integrated structure of the electric slip ring and the sub-disk rotating ring indirectly drives the sub-disk module to rotate.

[0007] Preferably, the sub-panel module is equipped with a correction device, which is located in the sensing cavity of the sub-panel module. The correction device includes a sensing rod, a sensor, and a cutting blade top block. The contact block of the cutting blade top block and the sensing rod are in contact connection. The sensing rod is connected to the sensor, and the cutting blade top block is also surrounded by a contact spring.

[0008] Preferably, the correction master disc or correction slave disc is further provided with a slave cutter disc, which includes a cutter tip and a beveling cutter head. The cutter tip is provided with a beveling cutter head and an oil / gas hole. The beveling cutter head has an oil / gas inlet hole corresponding to the position of the oil / gas hole. The correction master disc is provided with an oil atomization channel, and a transmission pipe is provided inside the oil atomization channel. By setting up relevant lubrication structures, the combination of the following structures can maintain lubrication and increase tool life.

[0009] Preferably, the contact spring is equipped with a lubricating oil spraying or transfer device. This device is connected to a transmission pipe via an oil atomization channel and electrically connected to a sensor. The lubricating oil spraying or transfer device can be a liquid atomizer, which atomizes the lubricating oil and sprays it into the cutting groove of the beveling head through the transmission pipe. Alternatively, a lubricating oil sprayer can directly spray liquid lubrication. The lubricating oil pump can directly introduce lubricating oil and its atomized body from external auxiliary devices such as an oil tank or hot liquid atomization device into the cutting groove of the beveling head. This ensures the blade remains lubricated for a long time. Furthermore, the electrical connection to the sensor allows for more intuitive and intelligent control under the constant monitoring of the cutting machine host.

[0010] Preferably, the cutting groove of the beveling head is X-shaped or trapezoidal. Trapezoidal and X-shaped cutting grooves make it easier to scrape away debris and cutting threads from the cutting blade, and also make it easier to store lubricating oil to lubricate the blade.

[0011] Preferably, the sub-cutter disc is provided with a sub-cutter disc bearing groove, and a sub-cutter disc bearing is fitted into the sub-cutter disc bearing groove. A bottom sealing cover ring is provided at the bottom of the sub-disc rotating ring, and the bottom sealing cover ring is placed under the cutter disc bearing, allowing the cutter disc bearing to rotate stably on the sub-cutter disc bearing groove. An auxiliary positioning bearing is also fitted onto the outer wall of the cutter tip. The dual-bearing auxiliary positioning structure allows the cutter tip and the bottom structure of the sub-cutter disc to rotate stably and smoothly in the disc groove, and also prevents the cutter tip from moving unsmoothly in areas with limited space.

[0012] Preferably, the correction disc is provided with a lifting connection hole and a rotating rod. The lifting connection hole is used to connect to the lifting mechanism rod of the cutting head to raise and lower the correction disc. The rotating rod is connected to the rotating structure of the cutting head and rotates synchronously under the drive of the cutting head. It can rotate itself while the cutting head moves and rotates, allowing for two different levels of precision during rotary cutting operations, overcoming the limitation of existing technologies that only allow one operation.

[0013] Preferably, a suspended base ring is provided on the top of the correction sub-disk between the correction master disk and the correction sub-disk. The suspended base ring is positioned between the correction master disk and the correction sub-disk, or the correction sub-disk is placed in the disk groove and then covered and fixed with the suspended base ring. This connecting structure allows the correction master disk and the correction sub-disk to form a mounting cavity with a certain height, allowing the sub-disk rotating ring and the electric slip ring structure set in it to rotate smoothly and fully within it. Furthermore, the thickness, model, and shape of the sub-disk rotating ring and the electric slip ring can be replaced according to their relevant configurations and models, making expansion and modularization relatively easy.

[0014] Preferably, the driver and the sensor are electrically connected to each other to transmit the rotation of the sensing sub-disk module and the sub-disk rotating ring combination structure, thus saving the relevant sensing signal path.

[0015] Preferably, a lead screw motor is installed at the top of the rotary drive rod. When the lead screw motor is not installed, the rotary drive rod will move up and down synchronously with the lifting rod. When the lead screw motor is installed, it can be linked with the lifting rod driven by the rotary motor of the correction sub-disc.

[0016] The beneficial effects of this invention are: 1. The cutting blade is equipped with an oil-air passage structure for guiding lubricating oil and blowing air, and is equipped with an air clamp and an air-liquid separator. The air-liquid separator introduces compressed air and lubricating oil from the air pump and liquid pump, which are then introduced into the air clamp and reach the oil-air passage to blow away the sticky threads, residues, waste liquid, etc. on the cutting blade, or the lowered cutting head directly introduces compressed air and lubricating oil into the correction sub-disc for lubrication and cleaning; 2. The sub-disc module and sub-disc rotating ring of the correction sub-disc are integrated with the correction blade disc. After the correction blade disc senses the blade's position at the first moment, it rotates and corrects the deviation. This correction speed is fast and will not cause large-scale damage or defects to the cut textile material due to untimely correction. 3. The correction cutter disc is set as a mother-daughter cutter holder mode. The correction disc also has a daughter cutter disc, which is equipped with a beveled cutter head to cut off the threads and other debris entangled on the main cutting blade, keeping the cutting blade clean; 4. The daughter cutter disc and the beveled cutter head are equipped with a lubricant introduction structure, which can maximize the protection of the daughter cutter disc, the beveled cutter head and the moving cutting blade, and increase the life of the cutter; 5. The daughter cutter disc is equipped with a cutter disc bearing and the cutter head is equipped with an auxiliary positioning bearing. The auxiliary positioning structure of the double bearing can make the cutter head and the bottom structure of the daughter cutter disc stably fit in the disc groove and rotate smoothly, and can also prevent the cutter head from moving unsmoothly in a small space; 6. The correction daughter disc is equipped with a lifting connection hole and a rotating rod. The lifting connection hole is used to connect the lifting mechanism rod of the cutting head to adjust the height of the correction cutter head. The rotating rod is connected to the rotating structure of the cutting head and rotates synchronously under the drive of the cutting head. It can rotate on its own while the cutting head can move and rotate, allowing for two different levels of precision during rotary cutting operations, breaking through the limitation of existing technologies that only allow one operation.

Detailed Implementation

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Main embodiment: A cutting head with a guide air and oil groove for cutting blade, comprising a guide mother disc 1 and a cutting head 101, wherein: a guide daughter disc 3 is provided on the top of the guide mother disc 1 or in the disc groove 2; the cutting head 101 includes a rotating frame 102 at the top, a guide daughter disc rotary motor 103 is provided at the bottom of the rotating frame 102, and a rotary drive rod 104 is also provided parallel to the side of the guide daughter disc rotary motor 103, the bottom of the rotary drive rod 104 is connected to or directly inserted into the rotary rod hole 26a of the guide mother disc 1; the guide daughter disc rotary motor 103 rotates the rotating frame 102, thereby driving the rotation of the guide mother disc 1 by the rotary rod 26, or directly pushing the guide mother disc 1 or the guide mother disc 1 and the guide daughter disc 3 to rotate;

[0032] Below the rotating frame 102, a cutting blade holder 105 is also provided. The cutting blade holder 105 is provided with a lifting rod 29. The cutting blade holder 105 includes a blade head holder 106 and a cutting blade 107. The blade head holder 106 uses its own ventilation clamp 108 to clamp and connect the cutting blade 107. The back of the cutting blade 107 is provided with an oil and gas passage 109 vertically from top to bottom. Above the ventilation clamp 108, a gas-liquid separator 110 is provided. The gas-liquid separator 110 extends out a machine head blade air supply pipe 111 and a machine head blade liquid supply pipe 112. The machine head blade air supply pipe 111 and the machine head blade liquid supply pipe 112 are connected to a gas-liquid valve 113. The gas-liquid valve 113 outputs lubricating fluid or gas to the oil and gas passage 109.

[0033] The cutting blade is equipped with an oil-air passage structure that guides lubricating oil and blows air. It is also equipped with an air clamp and an air-liquid separator. The air-liquid separator introduces compressed air and lubricating oil from the air pump and liquid pump, which are then introduced into the air clamp and reach the oil-air passage to blow away the sticky threads, residues, waste liquid, etc. on the cutting blade. Alternatively, the lowered cutting head can directly introduce compressed air and lubricating oil into the correction disc for lubrication and cleaning.

[0034] like Figure 7 The diagram shows a correction master disk 1, wherein: the correction master disk 1 has a recessed groove 2 at its top.

[0035] like Figure 3 , 4 As shown, the correction sub-disk 3 includes a sub-disk module 4, a sub-disk rotating ring 5, an electric slip ring 6, and a driver 7. The electric slip ring 6 is wound around the sub-disk rotating ring 5, and the sub-disk module 4 is disposed in the ring hole 5a of the sub-disk rotating ring 5. After assembly, it is placed in the disk groove 2, as shown. Figure 3 As shown, a suspended base ring 27 is also provided on the top of the correction sub-disc 3. After the correction sub-disc 3 is placed in the disk groove 2, the suspended base ring 27 is fixed on the cover.

[0036] like Figure 1 , 8 As shown, the energized driver 7 uses its own sliding teeth and belt (existing technology, not shown in the figure) to rotate the sub-disc rotating ring 5. The driver 7 is also equipped with a sensing spring 6a to sense and collect the rotation or stationary motion signals generated by the sub-disc rotating ring 5 and the electric slip ring 6. After the electric slip ring 6 and the sub-disc rotating ring 5 are integrated into a structure, they will indirectly rotate together with the moving sub-disc module 4. The rotation of the sub-disc module can drive the cutting blade to perform micro-cutting, which is suitable for fine manufacturing positions or fine correction of cutting errors.

[0037] Therefore, the present invention creates an oil-air passage structure with a cutting blade that guides lubricating oil and blows air, and includes a ventilation clamp and a gas-liquid separator. The gas-liquid separator introduces compressed air and lubricating oil from the air pump and liquid pump, guiding them to the ventilation clamp and reaching the oil-air passage. This blows away the adhesive threads, residue, waste liquid, etc., from the cutting blade, or allows the lowered cutting head to directly introduce compressed air and lubricating oil into the correction sub-disc for lubrication and cleaning. 2. The sub-disc module and rotating structure of the sub-disc rotating ring are integrated with the correction blade disc. The correction blade disc senses the blade's position and rotates to correct it immediately. This correction speed is fast and prevents large-scale damage due to untimely correction. 3. The corrective cutter disc is set as a mother-daughter cutter holder, and the corrective disc is also equipped with a daughter cutter disc. The daughter cutter disc is equipped with a beveled cutter head to cut the threads and other debris entangled on the main cutting blade and keep the cutting blade clean; 4. The daughter cutter disc and the beveled cutter head are equipped with a lubricant introduction structure, which can maximize the protection of the daughter cutter disc, the beveled cutter head and the moving cutting blade, and increase the life of the cutter; 5. The daughter cutter disc is equipped with a cutter disc bearing and the cutter head is equipped with an auxiliary positioning bearing. The auxiliary positioning structure of the double bearing can make the cutter head and the bottom structure of the daughter cutter disc stably fit in the disc groove and rotate smoothly, and can also prevent the cutter head in the small space from moving unsmoothly;

[0038] like Figure 5 , 6 As shown in Figures 7 and 11, the sub-disc module 4 is equipped with a correction device 8, which is located in the sensing cavity 9 of the sub-disc module 4. The correction device 8 includes a sensing rod 10, a sensor 11, and a cutting blade top block 12. These three components are basically the same as those in the prior art. The difference is that the present invention creates a contact block 12a of the cutting blade top block 12 that is in contact with the sensing rod 10. The sensing rod 10 is connected to the sensor 11, and the cutting blade top block 12 is also surrounded by a square contact spring 13. After the contact spring touches the groove wall in the sensing cavity 9, the sensor 11 collects the relevant data. The cutting machine host will issue a correction command or stop the machine for inspection as needed. The driver 7 and the sensor 11 are electrically connected to each other to transmit the rotation of the combined structure of the sub-disc module 4 and the sub-disc rotating ring 5, saving the relevant sensing signal path. According to existing technology, the cutting blade top block 12 corrects the cutting blade action using three correction wheels 35 set on the side of its own cutting blade hole 34.

[0039] like Figure 3 and 10As shown, the correction master disk 1 or correction slave disk 3 is further provided with a slave cutter disk 14. The slave cutter disk 14 can be an integral structure with the correction slave disk 3, a screw-in structure, or a detachable structure fastened to the center of the disk groove 2 of the correction master disk. The slave cutter disk 14 includes a cutter tip 15 and a beveling cutter head 16. The cutter tip 15 is provided with a beveling cutter head 16, and the cutter tip 15 is provided with an oil and gas hole 17a. The beveling cutter head 16 is provided with an oil and gas inlet hole 17b corresponding to the position of the oil and gas hole 17a. The correction master disk 1 is provided with an oil atomization channel 18, and a transmission pipe 19 is provided in the oil atomization channel 18. The cutter tip 15 in the correction slave disk here is provided with a related lubrication structure. The combination of the following structures can maintain the lubrication state and increase the tool life. Further, as Figure 10 As shown, a lubricating oil spraying or transfer device 20 is provided on the frame of the contact spring 13. If the impact of the cutting blade is sensed, lubricating oil will be sprayed while correcting the deviation, using lubricating oil to protect the cutting blade. The lubricating oil spraying or transfer device 20 is connected to the transmission pipe 19 and then to the oil atomization channel 18. Here, we directly set the lubricating oil transfer device 20 to be electrically connected to the sensor 11. The lubricating oil spraying or transfer device can be a liquid atomizer. After obtaining the lubricating oil, it is atomized and sprayed into the groove of the beveling cutter head 16 through the transmission pipe 19. Alternatively, the lubricating oil sprayer can directly spray liquid lubrication. The lubricating oil pump can directly introduce the lubricating oil and its atomized body from the external auxiliary device such as the oil tank or the hot liquid atomization device structure of this correction cutter head and then spray it into the groove of the beveling cutter head 16. In this way, the blade can be kept in a lubricated state for a long time. With the electrical connection to the sensor, it can be monitored by the cutting machine host at any time, which can enable more intuitive and intelligent control.

[0040] like Figure 10 As shown, the bevel cutting head 16 has an X-shaped groove. The X-shaped groove makes it easier to scrape away debris and cutting threads from the cutting blade, and it also easily forms a channel for the flow and retention of lubricating oil, which can lubricate and protect the cutting blade during use.

[0041] like Figure 4 , 8 As shown, the sub-cutter disc 14 is provided with a sub-cutter disc bearing groove 21, and a sub-cutter disc bearing 22 is fitted into the sub-cutter disc bearing groove 21. A bottom sealing cover ring 23 is provided at the bottom of the sub-disc rotating ring 5, and the bottom sealing cover ring 23 is placed under the cutter disc bearing 22 to allow the cutter disc bearing 22 to rotate stably on the sub-cutter disc bearing groove 21. An auxiliary positioning bearing 24 is also fitted onto the outer wall of the cutter tip 15. The auxiliary positioning structure of the double bearings can make the cutter tip and the bottom structure of the sub-cutter disc stably fit together in the disc groove 2 for smooth rotation, and can also prevent the cutter tip 15 from moving unsmoothly in the small space.

[0042] Therefore, the present invention integrates the sub-disc module, the sub-disc rotating ring structure, and the correction cutter disc into a single structure. The correction cutter disc senses the blade's position immediately and then rotates to correct the deviation. This correction speed is fast, preventing damage and defects to the textile material caused by delayed correction. 3. The correction cutter disc is designed as a mother-daughter cutter holder, and also includes a sub-cutter disc. The sub-cutter disc contains a beveled cutter head to cut away threads and other debris entangled on the main cutting blade, keeping the cutting blade clean. A lubricant inlet structure is provided for the sub-cutter disc and the beveled cutter head, maximizing protection for the sub-cutter disc, the beveled cutter head, and the moving cutting blade, increasing tool life. The sub-cutter disc has a cutter disc bearing, and the cutter tip has an auxiliary positioning bearing. This dual-bearing auxiliary positioning structure ensures stable and smooth rotation of the cutter tip and the bottom structure of the sub-cutter disc within the disc groove, preventing uneven movement of the cutter tip in areas with limited space.

[0043] While maintaining the structure of the correction master disk 1 and correction slave disk 3 in Embodiment 1, as follows Figure 9 and 11 As shown, the correction disc 3 is provided with a lifting connection hole 25 and a rotating rod 26. In existing cutting heads, which have their own rotating and lifting structures, the lifting connection hole 25 in this embodiment is used to connect the lifting rod 29 of the cutting head to raise and lower the correction disc. The rotating rod 26 is connected to the rotating structure of the cutting head via the rotating rod 30, and rotates synchronously under the drive of the rotating structure. While rotating itself, it can also be moved and rotated by the cutting head, allowing for two different levels of precision during rotary cutting operations, overcoming the limitation of existing technologies that only allow one operation. Figure 4 A suspended base ring 27 is also provided between the correction mother disk 1 and the correction daughter disk 3. Unlike embodiment 1, the suspended base ring 27 is provided between the correction mother disk 1 and the correction daughter disk 3, and the correction daughter disk 3 is placed in its ring structure. This connecting structure, which connects the upper and lower parts, can form an installation cavity with a certain height between the correction mother disk 1 and the correction daughter disk 3, allowing the daughter disk rotating ring and the electric slip ring structure set in it to rotate fully and smoothly inside. Furthermore, the thickness, model, and shape of the daughter disk rotating ring and the electric slip ring can be replaced according to the relevant configuration model, making expansion and modularization relatively easy.

[0044] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. For those skilled in the art, all other corresponding modifications made using the technical solutions and concepts of the present invention should fall within the protection scope of the claims of the present invention.
