A cutting head with multi-angle adjustable blades for cutting and processing.

Abstract

This invention relates to the field of sewing machinery manufacturing, specifically to a sewing machine head with a multi-angle adjustable blade for cutting and processing. The head includes a machine head base, with a lifting seat that moves vertically at its front end. Through the design of a collection component—comprising a first baffle, a second baffle, and a collection element—a relatively enclosed space is formed during blade sharpening, effectively confining debris and dust within this space for easy collection. Both larger metal fragments and fine dust particles fall into the collection element through various means, achieving automated collection and improving the cleanliness of the working environment. During blade sharpening, a magnetic cover, in a magnetic state, attracts dust through a through-slot, causing dust to accumulate near the magnetic cover. After sharpening, the magnetic cover loses its magnetism, and the dust falls into the collection element. This design makes dust more easily attracted and accumulated, improving dust collection efficiency.

Description

Technical Field

[0001] This invention relates to the field of sewing machinery manufacturing, specifically a sewing machine head with multi-angle adjustable blades for cutting and processing. Background Technology

[0002] In modern industrial production, the cutting and processing of both fabrics and sheets plays a crucial role. In traditional cutting processes, the angle of the cutting tools is usually fixed, which has significant limitations when facing complex and diverse cutting needs. Taking fabric cutting as an example, different styles and textures of fabric often require different cutting angles to achieve the desired pattern effect. Therefore, it is necessary to design a cutting head with multi-angle adjustable cutting tools. In the cutting of garment fabrics, for complex curves and angle changes, this cutting head, through the flexible rotation of multiple joints and a precise control system, allows the cutting tools to adjust their angles in real time according to the shape of the fabric, completing high-quality cutting work, greatly reducing errors, and improving product quality.

[0003] During long-term cutting use, the cutting edge of the knife will gradually become dull. Therefore, a sharpener needs to be equipped on the machine head. The sharpener can sharpen the knife in time to keep it sharp, thereby ensuring the accuracy and efficiency of cutting.

[0004] However, during the cutting process in industrial production, when the sharpener grinds the blade, it removes material from the blade surface through friction, thus making it sharp again. When the blade cuts the fabric vertically, fine metal shavings are generated and slide down the blade surface during this process. These metal shavings can easily contaminate the fabric, and these shavings and dust often fly around and are difficult to collect. Traditional collection methods are inefficient and cannot effectively confine the shavings and dust to a specific space, resulting in a decrease in the processing efficiency of the cutting head.

[0005] Therefore, it is necessary to propose a cutting head with multi-angle adjustable blades for cutting and processing to solve the above-mentioned technical problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a cutting head with a multi-angle adjustable tool for cutting and processing, which solves the technical problem that the debris and dust generated during tool grinding are difficult to collect, leading to a reduction in the processing efficiency of the cutting head.

[0014] Preferably, the collecting component includes a collecting cylinder, the top of which is snapped into a collecting tray, a limiting groove is formed on the left side of the collecting tray, and a limiting plate is snapped into the lower left side of the second baffle, the limiting groove and the limiting plate being compatible.

[0015] Preferably, a connecting plate is installed on the right side of the collection tray, and the connecting plate is snapped onto the bottom of the rectangular frame.

A slider that is slidably connected to the compression spring rod is snapped onto the right side of the dust cover. A horizontal groove is opened in the lower center of the dust cover. A limit block is snapped onto the top of the collection tray within the horizontal groove.

[0016] Preferably, a compressed gas generator is snapped onto the top of the telescopic cylinder.

[0018] Preferably, the top of the magnet cover is rotatably connected to a rotating ring, the bottom of the rotating ring is snapped with an inclined brush block that is tightly attached to the inner wall of the through groove, the front side wall of the through groove is equipped with a toothed plate, the top of the rotating ring is snapped with a turntable, the inside of the turntable is rotatably connected to a pair of second rollers, and one end of the cutter slides through the pair of second rollers.

[0019] Beneficial effects:

[0020] (1) By setting up the collection component, the present invention can form a relatively closed space during the tool grinding process by setting up the first baffle, the second baffle and the collection component, effectively confining the debris and dust in this space, which is convenient for subsequent collection. Whether it is a large piece of metal or a small piece of dust, it can fall into the collection component in different ways, realizing automated collection and improving the cleanliness of the working environment. When the tool is grinding, the magnetic cover in the magnetic state can attract dust through the through groove, causing the dust to accumulate near the magnetic cover. After grinding, it loses its magnetism and the dust falls into the collection component. This design makes the dust easier to be attracted and accumulated, improving the dust collection efficiency.

[0021] (2) The present invention can ensure that the grinding effect of the tool is more uniform and fine by using a graded grinding method, thereby improving the grinding efficiency of the tool. Since the grinding component has a stepped structure, with the cooperation of the telescopic groove, the expansion spring rod and the sealing arc seat, when the electric push rod drives the grinding component to move to different horizontal positions, the sealing cover on the first baffle plate always squeezes the sealing arc seat, so that it slides outward in the telescopic groove to maintain a sealed state. This can ensure that the dust is limited to the range of the collection component when adapting to different grinding stages, greatly improving the dust collection efficiency of the collection component and reducing the dust concentration in the working environment.

[0022] (3) By setting up a collection component, the present invention can automatically open the dust cover when the grinding component moves, causing the second baffle to exert pressure on the dust cover during the grinding process, providing operating space for the tool. After grinding is completed, the pressure disappears, and the compression spring rod drives the dust cover to reset and cover the opening of the collection component. This automatic opening and closing design of the dust cover does not require manual intervention, reduces the risk of dust leakage caused by human error, and improves the overall stability and reliability of the equipment.

Detailed Implementation

[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] like Figures 1-5As shown, a cutting head with a multi-angle adjustable cutter for cutting and processing includes a headstock 1. A lifting seat 11 that moves vertically is provided at the front end of the headstock 1. A pair of limiting seats 12 for limiting the lifting seat 11 are installed on one side of the headstock 1. A cutter 13 is provided on one side of the lifting seat 11. A multi-angle control seat 14 for controlling the rotational movement of the cutter 13 is installed on one side of the headstock 1 and below the lifting seat 11. A control mechanism for stable rotation of the cutter 13 is provided below the headstock 1. The cutter head holder 15 has a connecting seat 16 snapped onto the side wall of the right-side limiting seat 12. An electric push rod 17 is snapped onto the lower part of the connecting seat 16. A grinding assembly 18 is located at the moving end of the electric push rod 17 and is used to grind the cutter 13. A collecting assembly 2 is located on the grinding assembly 18 and is used to automatically collect debris during the grinding process. The collecting assembly 2 includes a first baffle 21, a second baffle 22, and a collecting element 27. The first baffle 21 is configured with… On the grinding assembly 18, the second baffle 22 is snapped onto the underside of the multi-angle control seat 14. A sloping groove 23 is formed at one end of the second baffle 22 near the first baffle 21. A collecting component 27 is positioned below the first baffle 21 and the second baffle 22. The collecting assembly 2 also includes a magnet cover 24 installed inside the second baffle 22. The magnet cover 24 has a C-shaped cross-section. Symmetrically arranged sealing elements are installed at both ends of the first baffle 21 near the second baffle 22. The rear side wall of the cover 25 and the magnetic cover 24 is provided with a touch switch 26 that is in close contact with the sealing cover 25. The sealing cover 25 is in close contact with the side wall of the magnetic cover 24. The first baffle 21 is one-quarter of a circle and the second baffle 22 is three-quarters of a circle. The first baffle 21 and the second baffle 22 can be combined to form a complete circular enclosure. The magnetic cover 24 has a through groove 240 that can pass through the cutter 13. The through groove 240 gradually narrows from one end to the other end.

[0040] It should be noted that the first baffle 21 and the second baffle 22 in the collecting component 2 are initially separate. When the tool 13 needs to be sharpened, the electric push rod 17 drives the sharpening component 18 to move towards the tool 13. As the sharpening component 18 approaches, the first baffle 21 gradually approaches the second baffle 22. Finally, the first baffle 21 and the second baffle 22 combine to form a complete circular enclosure. Then, the lifting seat 11 moves the tool 13 to be surrounded inside the complete circular enclosure. At the same time, the collecting component 27 also moves synchronously to the bottom of the first baffle 21 and the second baffle 22. When the first baffle 21 contacts the touch switch 26, the sealing cover 25 is pressed tightly against the side wall of the magnetic cover 24, triggering the magnetic cover 24 to enter the magnetic state. During the grinding process of the tool 13, larger metal chips fall directly into the collection unit 27 located below the first baffle 21 and the second baffle 22 due to gravity. As for dust, since the magnetic cover 24 is in a magnetic state and the through groove 240 gradually narrows from the top end to the bottom end, the dust generated by the grinding of the tool 13 is attracted at the through groove 240. As the grinding continues, the dust accumulates near the magnetic cover 24. After the grinding is completed, the electric push rod 17 drives the grinding assembly 18 away from the tool 13, the first baffle 21 and the second baffle 22 are separated, the touch switch 26 is reset, the magnetic cover 24 loses its magnetism, and at this time, the dust attracted by the through groove 240 loses its magnetic restraint, accumulates and falls into the collection unit 27, thus realizing the automated collection of chips.

[0041] It is worth noting that the multi-angle control seat 14 is equipped with a positioning system, such as a machine vision system or a laser positioning system. The machine vision system can use a camera to capture the marks or feature points on the fabric, identify the position and direction of the fabric, and match it with the preset cutting path. The laser positioning system can emit a laser beam to form a reference line on the fabric, helping the machine head seat 1 to accurately cut along the preset path.

[0042] It is worth noting that the second baffle 22 has an inclined groove 23 at one end near the first baffle 21. This inclined groove 23 guides the debris and dust to the collection component 27, ensuring that the debris and dust generated during the formation and grinding of the first baffle 21 and the second baffle 22 can enter the collection component 27 more smoothly, thereby improving the collection efficiency.

[0043] By setting up the collection component 2, the present invention, through the arrangement of the first baffle 21, the second baffle 22 and the collection component 27, can form a relatively closed space during the grinding process of the tool 13, effectively confining the debris and dust within this space, facilitating subsequent collection. Whether it is a large piece of metal or a tiny dust particle, it can fall into the collection component 27 in different ways, realizing automated collection and improving the cleanliness of the working environment. The design of the through groove 240, which gradually narrows from one end to the other, makes it easier for dust to be attracted and accumulate near the magnet cover 24.

[0044] like Figure 3 , Figure 4 and Figure 6 As shown, the sharpening assembly 18 includes a rectangular frame 181 fixedly connected to the moving end of the electric push rod 17. A rotating rod is rotatably connected inside the rectangular frame 181. A motor that drives the rotating rod to rotate is mounted on the top of the rectangular frame 181 via a motor mount. Three telescopic cylinders 182 are installed at the end of the rectangular frame 181 away from the electric push rod 17. Telescopic springs 183 are sleeved inside the telescopic cylinders 182. A telescopic rod 184 is snapped onto the end of the telescopic spring 183 away from the telescopic cylinder 182. A support is installed at the end of the telescopic rod 184 away from the telescopic spring 183. The support seat 185 has a first baffle plate 21 snapped onto the outside of the support seat 185. Three first rollers 186 are rotatably connected to the end of the support seat 185 away from the telescopic rod 184 and the outside of the rotating rod. Sharpening conveyor belts 187 are driven to the outside of the first rollers 186 at both ends. The bottom sharpening conveyor belt 187 is a coarse sharpening belt, the middle sharpening conveyor belt 187 is a medium-coarse sharpening belt, and the top sharpening conveyor belt 187 is a fine sharpening belt. The three sharpening conveyor belts 187 are distributed in a stepped structure.

[0045] It should be noted that after the motor starts, it drives the rotating rod inside the rectangular frame 181 to rotate. The rotating rod is connected to the first roller 186 located on the right side. When the rotating rod rotates, it drives the first roller 186 located on the right side to rotate. When the first roller 186 on the right side rotates under the drive of the rotating rod, it drives the other first roller 186 to rotate through the friction of the grinding conveyor belt 187. When the tool 13 needs to be ground, the electric push rod 17 pushes the rectangular frame 181 and the entire grinding assembly 18 to move toward the tool 13. As multiple sets of grinding conveyor belts 187 with a stepped structure are operated, the tool 13 passes through the coarse grinding belt, the medium coarse grinding belt and the fine grinding belt in sequence for grinding. When changing the grinding stage, the tool 13 needs to be moved to different height positions by the lifting seat 11. At the same time, the electric push rod 17 needs to drive the grinding assembly to move to different horizontal positions.

[0046] Under the action of telescopic cylinder 182, telescopic spring 183 and telescopic rod 184, support seat 185 can be adjusted according to the position and pressure of tool 13 to ensure that the grinding conveyor belt 187 and tool 13 maintain appropriate contact pressure.

[0047] This invention, through graded grinding, can ensure a more uniform and detailed grinding effect on the cutting tool 13, thereby improving the grinding efficiency of the cutting tool 13. Since the cutting tool 13 may experience varying degrees of wear and deformation during the cutting process, its shape and size may also change. The stepped grinding conveyor belt 187 can better adapt to these changes. When the cutting tool 13 contacts the grinding conveyor belt 187, the grinding belts of different heights can be adjusted according to the actual shape and size of the cutting tool 13, ensuring that each part can be effectively ground.

[0048] It is worth noting that the bottom coarse grinding blade is the lowest and closer to the collector 27. When cutting the blade 13, the debris generated is more likely to fall into the collector 27. At the same time, the debris and dust that fall off the blade 13 are more likely to move towards the collector 27 under the guidance of gravity and the stepped structure. This ensures that the debris and dust can flow more concentratedly to the collector 27, thus improving the collection efficiency.

[0049] like Figures 7-8 As shown, telescopic grooves 221 are provided at both the front and rear ends of the right side of the magnet cover 24. An expansion spring rod 222 arranged in a linear array is slidably connected inside the telescopic groove 221. A sealing arc-shaped seat 223 is snapped onto the end of the expansion spring rod 222 away from the magnet cover 24. One end of the touch switch 26 is slidably connected to the sealing arc-shaped seat 223 located at the rear end. A limit rod 224 is installed on the top of the sealing arc-shaped seat 223. An arc-shaped groove is provided on the top of the magnet cover 24 that is slidably connected to the outer side of the limit rod 224.

[0050] It should be noted that when the electric actuator 17 moves the grinding assembly to different horizontal positions, the sealing cover 25 on the first baffle 21 gradually contacts the sealing arc seat 223 located at the rear end. The sealing arc seat 223 is squeezed by the sealing cover 25, overcomes the elastic force of the expansion spring rod 222, and slides outward in the telescopic groove 221. This helps to keep the sealing arc seat 223 and the sealing cover 25 in a sealed state. It can ensure that the dust is confined within the range of the collection component 27 when adapting to different grinding stages, which greatly improves the dust collection efficiency of the collection component 2 and reduces the dust concentration in the working environment.

[0051] like Figure 4 and Figure 9As shown, the collecting component 27 includes a collecting cylinder 271, and a collecting tray 272 is snapped onto the top of the collecting cylinder 271. The collecting tray 272 has a through-shaped structure, and a limiting groove 273 is opened on the left side of the collecting tray 272. A limiting plate 274 is snapped onto the lower left side of the second baffle 22. The limiting groove 273 and the limiting plate 274 are compatible.

[0052] It should be noted that when the collecting component 27 moves, its connected collecting tray 272 can engage with the limiting plate 274 below the second enclosure 22, ensuring that the collecting tray 272 is quickly positioned below the second enclosure 22.

[0053] like Figure 9 and Figure 10 As shown, a connecting plate 275 is installed on the right side of the collection tray 272. The connecting plate 275 is snapped onto the bottom of the rectangular frame 181. A slide rail groove 276 is opened on the top of the connecting plate 275. A compression spring rod 277 arranged horizontally is installed on the right side wall of the collection tray 272. A dust cover 278 is set above the compression spring rod 277. The left side of the dust cover 278 is tightly attached to the bottom of the second baffle 22. The dust cover 278 has a circular structure. A slider 279 that is slidably connected to the compression spring rod 277 is snapped onto the right side of the dust cover 278. A horizontal groove is opened in the middle of the bottom of the dust cover 278. A limit block 2781 is snapped onto the top of the collection tray 272 within the horizontal groove.

[0054] It should be noted that when the sharpening assembly 18 moves along the second baffle 22, the lower part of the second baffle 22 exerts a squeezing force on the dust cover 278. This squeezing force causes the slider 279 on the right side of the dust cover 278 to slide along the slide rail groove 276 at the top of the connecting plate 275. As the slider 279 slides, the compression spring rod 277 connected to the slider 279 is stretched. At this time, the dust cover 278 gradually moves away from the collection tray 272, making room for the sharpening operation of the tool 13. When the sharpening is finished, the sharpening assembly 18 resets. At this time, the squeezing force on the dust cover 278 disappears, the compression spring rod 277 releases its spring potential energy, and the spring potential energy drives the slider 279 to slide in the opposite direction along the slide rail groove 276, thereby driving the dust cover 278 to reset. The transverse groove in the middle of the square and the limiting block 2781 at the top of the collection tray 272 cooperate with each other to limit the sliding range of the dust cover 278, ensuring that the dust cover 278 can accurately cover the opening of the collection piece 27 when it is reset. During the sharpening process, the movement of the sharpening assembly 18 will automatically open the dust cover 278, providing sufficient operating space for the tool 13. After sharpening is completed, the dust cover 278 can quickly cover the opening of the collection piece 27, effectively preventing the dust inside the collection piece 27 from leaking again during the movement of the headstock 1. By automatically opening and closing the dust cover 278, no manual intervention is required, reducing the risk of dust leakage caused by human error. At the same time, it also improves the overall stability and reliability of the equipment.

[0055] like Figure 4 , Figure 8 and Figure 11 As shown, a compressed gas generator 231 is snapped onto the top of the telescopic cylinder 182. The output end of the compressed gas generator 231 is connected to the inner cavity of the first baffle 21 through a pipe. Multiple sets of first injection holes 232 are opened at the end of the first baffle 21 facing away from the grinding conveyor belt 187. A baffle 233 is installed at the end of the sealing cover 25 at the rear end away from the first baffle 21. A second injection hole 234 in a linear array is opened at the side wall of the baffle 233 near the through groove 240. The injection direction of the second injection hole 234 is arranged towards the bottom. The first injection hole 232 and the second injection hole 234 are connected to the pipe in the inner cavity of the first baffle 21.

[0056] It should be noted that when the tool 13 is being polished, the compressed gas machine 231 is started. After the compressed gas enters the inner cavity of the first baffle 21, the gas is ejected from these first injection holes 232. The ejected gas forms an airflow, which acts on the dust generated during the polishing process. The airflow blows the dust along the inside of the first baffle 21 and the second baffle 22, causing the dust to flow towards the side wall of the through groove 240. The dust blown by the airflow is more easily attracted by the magnetic cover 24 near the through groove 240, thereby achieving dust collection.

[0057] When the grinding of the tool 13 is finished, gas will be ejected from the second injection hole 234, which can further spray the dust remaining in the through groove 240, thereby improving the dust collection effect.

[0058] like Figure 9 and Figure 12 As shown, a filter hole 235 is provided at the snap-fit ​​part below the collection tray 272 and above the collection cylinder 271. Filter cotton is snap-fitted and installed inside the filter hole 235. The collection cylinder 271 has a conical structure. A magnet post 2711 is snap-fitted and installed in the middle of the collection cylinder 271. A conical seat 2712 is snap-fitted and installed at the top of the magnet post 2711.

[0059] It should be noted that the gas ejected from the second injection hole 234 flows into the collection tray 272, and the debris collides on the conical seat 2712 and accumulates along the inside of the collection cylinder 271. The gas is then discharged from the filter hole 235. The filter cotton can filter dust particles and improve the collection effect inside the collection cylinder 271, while the magnetic column 2711 can adsorb debris, making it easier to collect and process debris when the collection tray 272 is disassembled later.

[0060] The top of the magnet cover 24 is rotatably connected to a rotating ring 241. The bottom of the rotating ring 241 is snapped with an inclined brush block 242 that is tightly attached to the inner wall of the through groove 240. A toothed plate 243 is installed on the front side wall of the through groove 240. The top of the rotating ring 241 is snapped with a turntable 244. A pair of second rollers 245 are rotatably connected inside the turntable 244. One end of the cutter 13 slides through the pair of second rollers 245.

[0061] It should be noted that when the cutting tool 13 changes to different angles for grinding, it drives the second roller 245 and the turntable 244 to rotate synchronously on the second baffle 22. At the same time, it also drives the rotating ring 241 and the inclined brush block 242 to rotate along the through groove 240. The brush on the inclined brush block 242 can further clean the dust on the side wall of the through groove 240. When the rotating ring 241 drives the inclined brush block 242 to disengage from the through groove 240, the brush on the inclined brush block 242 will expand against the toothed plate 243. The teeth on the toothed plate 243 can vibrate the brush, which facilitates the self-cleaning effect of the inclined brush block 242.

[0062] The working principle of this invention is as follows: The cutting head with a multi-angle adjustable blade 13, used for cutting and processing, when the blade 13 needs to be sharpened, the electric push rod 17 drives the sharpening assembly 18 to move towards the blade 13. As the sharpening assembly 18 approaches, the first baffle 21 gradually approaches the second baffle 22. Finally, the first baffle 21 and the second baffle 22 combine to form a complete circular baffle. Then, the lifting seat 11 moves the blade 13 to be surrounded inside the complete circular baffle. Simultaneously, the collecting component 27 also moves synchronously to the bottom of the first baffle 21 and the second baffle 22. When the first baffle 21 contacts the touch switch 26, the sealing cover 25 presses tightly against the side wall of the magnet cover 24, triggering the magnet cover 24 to enter a magnetic state. During the grinding process of tool 13, larger metal fragments fall directly into the collection unit 27 located below the first baffle 21 and the second baffle 22 due to gravity. As for dust, since the magnetic cover 24 is in a magnetic state and the through groove 240 gradually narrows from the top end to the bottom end, the dust generated by the grinding of tool 13 is attracted at the through groove 240. As the grinding continues, the dust accumulates near the magnetic cover 24. After the grinding is completed, the electric push rod 17 drives the grinding tool assembly 18 away from the tool 13, the first baffle 21 and the second baffle 22 are separated, the touch switch 26 is reset, the magnetic cover 24 loses its magnetism, and at this time, the dust attracted by the through groove 240 loses its magnetic binding force, accumulates and falls into the collection unit 27, thus realizing the automated collection of fragments.

[0063] The motor starts, driving the rotating rod to rotate, which in turn drives the first roller on the right to rotate. The friction of the grinding conveyor belt 187 drives the other first rollers 186 to rotate, causing the grinding conveyor belt 187 to operate and grind the tool 13. When the grinding assembly 18 moves along the second baffle 22, the lower part of the second baffle 22 exerts a pressing force on the dust cover 278. This pressing force causes the slider 279 on the right side of the dust cover 278 to slide along the slide rail groove 276 at the top of the connecting plate 275. As the slider 279 slides, the compression spring rod 277 connected to the slider 279 is stretched. At this time, the dust cover... As the cover 278 gradually moves away from the collection tray 272, space is made for the sharpening operation of the blade 13. When the sharpening is finished, the sharpening assembly 18 is reset. At this time, the squeezing force on the dust cover 278 disappears, the compression spring rod 277 releases the spring potential energy, and the spring potential energy drives the slider 279 to slide in the opposite direction along the slide rail groove 276, thereby driving the dust cover 278 to reset. The transverse groove in the middle of the lower part of the dust cover 278 and the limiting block 2781 at the top of the collection tray 272 cooperate with each other to limit the sliding range of the dust cover 278, ensuring that the dust cover 278 can accurately cover the opening of the collection piece 27 when it is reset.

[0064] When the tool 13 is being ground, the compressed gas generator 231 is started. After the compressed gas enters the inner cavity of the first baffle 21, the gas is ejected from the first injection holes 232. The ejected gas forms an airflow that acts on the dust generated during the grinding process. The airflow blows the dust along the inside of the first baffle 21 and the second baffle 22, causing the dust to flow toward the side wall of the through groove 240. The dust blown by the airflow is more easily attracted by the magnetic cover 24 near the through groove 240, thereby achieving dust collection. When the grinding of the tool 13 is finished, the gas will be ejected from the second injection hole 234, which can further spray the dust remaining in the through groove 240, improving the dust collection effect.
