Description

Technical Field

[0001] This invention relates to the technical field of cutting equipment, and in particular to a cutting device. Background Technology

[0002] Cutting machines are suitable for dividing and cutting sheet materials in various industries. They do not require any molds; they are controlled by system software and then directly cut the products. They are currently the cutting equipment used in many industries.

[0003] With societal progress and the pursuit of increased production efficiency, more and more industries are adopting assembly line production. In the fiber mat manufacturing industry, after the fiber mats are produced on the assembly line, they need to be cut. However, since the fiber mats are continuously being produced and in constant motion, existing cutting equipment struggles to accurately cut the continuously flowing mats. Therefore, each time cutting is required, the production line must be stopped to halt the movement of the fiber mats. This constant shutdown not only impacts production efficiency but also increases the risk of damage to the equipment. Summary of the Invention

[0004] To improve the production efficiency of fiber mats by stopping the production equipment every time the fiber mat is cut, this application provides a cutting device.

[0005] The cutting device provided in this application adopts the following technical solution:

[0006] A cutting device, comprising:

[0007] A cutting mechanism for cutting fiber mats, wherein the cutting direction of the cutting mechanism is perpendicular to the conveying direction of the fiber mats;

[0008] A support mechanism is used to mount the cutting mechanism;

[0009] A sliding mechanism is used to drive the support mechanism to move. The direction of movement of the support mechanism is parallel to the conveying direction of the fiber mat, and the moving speed of the support mechanism is the same as the conveying speed of the fiber mat.

[0010] By adopting the above technical solution, the sliding mechanism drives the support mechanism to move, which in turn drives the cutting mechanism to move while cutting. The cutting mechanism and the fiber mat are adjusted to move at the same speed, so that the cutting mechanism and the fiber mat remain relatively stationary. This allows the fiber mat to be cut without stopping the production equipment, which is beneficial to improving the production efficiency of the fiber mat.

[0011] Optionally, the support mechanism includes a support base, a cutting table, and a support frame. The cutting table is mounted on the support base, the support frame is mounted on the side of the cutting table away from the support base, and the cutting mechanism is mounted on the support frame. The support base is provided with multiple bearing seats, the lead screw passes through the bearing seats and is rotatably connected to the bearing seats, and the slider is sleeved on the lead screw between two of the bearing seats.

[0012] By adopting the above technical solution, the bearing housing not only stably fixes the lead screw to the support base, allowing the lead screw to rotate smoothly and improving the sliding stability of the slider and support mechanism, but also limits the slider, preventing it from slipping off the lead screw during sliding, thus improving the safety of the cutting device.

[0013] Optionally, the sliding mechanism includes a slide rail and a first driving assembly. The slide rail is disposed on the support base and extends along the support base, and the cutting table is slidably connected to the slide rail. The first driving assembly includes a first driving member, a lead screw, and a slider. The driving end of the first driving member is connected to the lead screw. The lead screw is disposed on the support base and parallel to the slide rail. The slider is threadedly connected to the lead screw and is fixedly connected to the cutting table.

[0014] By adopting the above technical solution, when the first drive rod drives the lead screw to rotate, the slider can slide along the lead screw, thereby driving the cutting table and the support frame installed on the cutting table to slide along the slide rail; by adjusting the rotation speed of the first drive component, the sliding speed of the slider and the cutting table can be adjusted so that the sliding speed of the cutting table and the support frame matches the production speed of the fiber mat. At this time, the cutting mechanism remains relatively stationary with the fiber mat, so that the fiber mat can be cut without stopping the production equipment, which is beneficial to improving the production efficiency of the fiber mat.

[0015] Optionally, the cutting mechanism includes a mounting base, a second drive assembly, and a cutting assembly. The cutting assembly is mounted on the mounting base, and the second drive assembly is used to drive the mounting base to reciprocate along the length direction of the support frame.

[0016] The second drive assembly includes a second drive member, a first sprocket, a second sprocket, and a first chain. The drive end of the second drive member is connected to the first sprocket or the second sprocket. The first sprocket and the second sprocket are respectively disposed at both ends of the support frame. One end of the first chain passes around the first sprocket and is connected to the mounting base, and the other end of the first chain passes around the second sprocket and is connected to the mounting base.

[0017] By adopting the above technical solution, when the second drive component is activated, the first sprocket and the second sprocket can rotate in the same direction through the transmission of the first chain. The mounting base can also move towards either the first or second sprocket through the traction of the chain. Since the first and second sprockets are respectively located at both ends of the support frame, the mounting base can reciprocate along the support frame through the forward and reverse rotation of the second drive component, thereby achieving cutting. The second drive component uses chain drive to achieve the reciprocating motion of the mounting base, which not only has a simple structure, facilitating subsequent maintenance or replacement, but also allows the sprockets and chain to adapt to various harsh environments, thus improving the service life of the second drive component. Compared to belt drive, chain drive is less prone to slippage and has higher transmission efficiency.

[0018] Optionally, the cutting assembly includes a cutting base, a cutting blade, a third driving assembly, and a fourth driving assembly. The cutting base is hinged to the mounting base. The cutting blade and the third driving assembly are mounted on the cutting base. The third driving assembly is used to drive the cutting blade to rotate. The fourth driving assembly includes a telescopic fourth driving member and a connecting rod. The bottom end of the fourth driving member is hinged to the mounting base. The telescopic end of the fourth driving member is connected to the connecting rod. The other end of the connecting rod is hinged to the third driving assembly.

[0019] By adopting the above technical solution, since the third drive assembly is mounted on the cutting seat, when the telescopic end of the fourth drive component retracts, the fourth drive component can pull the third drive assembly and the cutting seat to rotate around the hinge axis between the cutting seat and the mounting seat via the connecting rod. This achieves downward pressure on the cutting seat, allowing the cutting blade to contact the fiber mat and cut it. After cutting, the fourth drive component extends, and the cutting seat rises, moving the cutting blade away from the fiber mat. This prevents the cutting blade from obstructing subsequent production of the fiber mat, which is beneficial for maintaining the production line of the fiber mat and preserving production efficiency.

[0020] Optionally, the third drive assembly includes a third drive member, a first transmission rod, and a second transmission rod. The first transmission rod and the second transmission rod are rotatably connected to the cutting seat. The drive end of the third drive member is provided with a first bevel gear. The first transmission rod is provided with a second bevel gear that meshes with the first bevel gear. One end of the first transmission rod is provided with a first sprocket, and one end of the second transmission rod is provided with a second sprocket. A first chain connects the first sprocket and the second sprocket. The end of the second transmission rod away from the second sprocket is connected to the cutting blade.

[0021] By adopting the above technical solution, when the cutting blade is cutting at high speed, contact with the fiber pad will cause the cutting blade to vibrate. Since the third drive component and the cutting blade are indirectly connected through the first transmission rod and the second transmission rod, and there is no direct connection between the two, the vibration generated by the cutting blade is not easily transmitted to the third drive component. This helps to prevent the vibration generated by the cutting blade from affecting the third drive component, thereby protecting the third drive component and improving its service life.

[0022] Optionally, the cutting device further includes a tensioning mechanism mounted on the support frame, the tensioning mechanism being used to give the fiber pad a certain tension.

[0023] By adopting the above technical solution, the tensioning mechanism gives the fiber pad a certain tension when cutting the fiber pad, which helps to prevent the fiber pad from wrinkling or shifting during cutting, so that the cutting mechanism can cut the fiber pad. This not only helps to make the cut of the fiber pad flat and smooth, but also helps to improve the cutting accuracy.

[0024] Optionally, the tensioning mechanism includes a tensioning assembly, a telescopic fifth drive member, and a sixth drive assembly;

[0025] The tensioning assembly includes a roller frame and two tension rollers. The roller frame is disposed on both sides of the cutting table. The tension rollers are rotatably connected to the roller frame. The two tension rollers are respectively disposed on both sides of the cutting device. The telescopic end of the fifth driving member extends toward the cutting table and is connected to the roller frame. The sixth driving assembly is used to drive the two tension rollers to rotate in opposite directions.

[0026] By adopting the above technical solution, when the fifth driving component extends, it can drive the roller frame and tension roller to move towards the cutting table until the tension roller can fully press against the fiber pad. Then, the sixth driving component drives the two tension rollers to rotate in opposite directions. The tension rollers pull the fiber pad through friction, taut and straightening the fiber pad located between the two tension rollers, so that the fiber pad has a certain tension so that the cutting mechanism can cut the fiber pad.

[0027] Optionally, the sixth drive assembly includes a sixth drive member and a gear set. The gear set includes a drive gear, two driven gears, and a connecting gear. The drive gear is disposed at the drive end of the sixth drive member. The two driven gears are respectively sleeved on one end of the two tension rollers. The drive gear meshes with one of the driven gears, and the other driven gear is connected to the drive gear through the connecting gear.

[0028] By adopting the above technical solution, when the sixth driving component drives the driving gear to rotate clockwise, the driven gear directly meshing with the driving gear rotates counterclockwise, while the driven gear connected to the driving gear via the connecting gear rotates clockwise. Through the ingenious transmission of the gear set, the sixth driving component only needs to rotate in one direction to achieve the rotation of the two tension rollers in different directions. The structure is simple and facilitates subsequent maintenance or replacement.

[0029] Optionally, the tensioning mechanism includes a second tensioning component and a telescopic seventh drive component;

[0030] The second tensioning assembly includes a hinge seat, two pressure rods, and a hinge rod. The telescopic end of the seventh drive member is connected to the hinge seat. Both ends of the hinge rod are hinged to the hinge seat and the pressure rod, respectively. A sliding rod passes between the two pressure rods. The pressure rod and the sliding rod are slidably connected. Limit blocks are provided at both ends of the sliding rod. A tension spring is provided between the two pressure rods. One end of the tension spring is connected to one of the pressure rods, and the other end of the tension spring is connected to the other pressure rod.

[0031] By adopting the above technical solution, when the seventh driving member extends, its telescopic end drives the hinge seat and pressure rod to press down towards the cutting table, allowing the pressure rod to fully press against the fiber pad on the cutting table. After the pressure rod presses against the fiber pad, the seventh driving member continues to drive the hinge seat to press down. Since the pressure rod can no longer press down, the two pressure rods slide towards the ends of the sliding rod through the push of the hinge rod. This allows the two pressure rods to tighten and straighten the fiber pad pressed in the middle, facilitating the cutting mechanism to cut the fiber pad. When the hinge seat rises, the tension spring pulls the two pressure rods towards the middle, restoring them to their original positions for the next cut.

[0032] Optionally, an anti-slip pad is provided on the side of the pressure bar facing the cutting table, and the anti-slip pad is provided with anti-slip particles.

[0033] By adopting the above technical solution, the anti-slip mat and anti-slip particles increase the friction between the pressure rod and the fiber mat, so that when the pressure rod slides to both ends of the sliding rod, it can fully tighten and straighten the fiber mat, so that the cutting mechanism can cut the fiber mat. This helps to prevent slippage between the pressure rod and the fiber mat, which would cause the fiber mat to lose its tautness during cutting and thus affect the cutting accuracy.

[0034] In summary, the embodiments of this application possess at least one of the following beneficial effects:

[0035] 1. The cutting table and support frame are driven to slide along the slide rail by the first drive component. The cutting mechanism installed on the support frame can remain relatively stationary with the fiber mat, so that the fiber mat can be cut without stopping the production equipment, which is beneficial to improving the production efficiency of the fiber mat.

[0036] 2. Through the transmission of the first and second transmission rods, the third driving component indirectly drives the cutting blade to rotate at high speed. This helps prevent the cutting blade from vibrating during high-speed cutting, thus protecting the third driving component and extending its service life.

[0037] 3. By setting a tensioning mechanism, the fiber pad is given a certain tension, which helps to prevent the fiber pad from wrinkling or shifting when cutting the fiber pad. This not only helps to make the cut of the fiber pad flat and smooth, but also helps to improve the cutting accuracy. Attached Figure Description

[0054] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0055] Example 1

[0056] Embodiment 1 of this application discloses a cutting device. (Refer to...) Figure 1A cutting device includes a support mechanism 1, a sliding mechanism 2, a cutting mechanism 3, and a tensioning mechanism 4. The support mechanism 1 includes support seats 11 on both sides, a cutting table 12 mounted on the support seats 11, and a support frame 13. The two ends of the cutting table 12 are slidably connected to the support seats 11 on both sides. The cutting table 12 is used to carry the fiber mat. The fiber mat produced by the production line equipment enters the cutting table 12 and moves forward continuously under the power provided by the production line equipment. The support frame 13 is fixedly mounted on the side of the cutting table 12 away from the support seats 11. The support frame 13 is used to support and fix the cutting mechanism 3 and the tensioning mechanism 4 on the cutting table 12. The sliding mechanism 2 is used to drive the cutting table 12 to slide back and forth along the length of the support seats 11. Since the support frame 13 is fixedly mounted on the cutting table 12, when the cutting table 12 moves, the support frame 13 and the cutting mechanism 3 and the tensioning mechanism 4 mounted on the support frame 13 will also move together. The cutting mechanism 3 is used to cut the fiber mat on the cutting table 12. The tensioning mechanism 4 is used to maintain a certain tension on the fiber mat during cutting so that the limiting mat can be fully cut by the cutting mechanism 3.

[0057] Reference Figure 1 and Figure 2 The support frame 13 includes a first bracket 131, a second bracket 132, and a connecting frame 133. The first bracket 131 and the second bracket 132 are arranged parallel to each other, and the connecting frame 133 is used to connect the first bracket 131 and the second bracket 132. Specifically, in this embodiment, both the first bracket 131 and the second bracket 132 are "U"-shaped brackets, and the connecting frame 133 is disposed between the first bracket 131 and the second bracket 132, and is located at the top ends of both sides of the first bracket 131 and the second bracket 132. By connecting the first bracket 131 and the second bracket 132 through the connecting frame 133, the first bracket 131 and the second bracket 132 are less likely to shake when the cutting table 12 slides back and forth, which helps to improve the support stability of the first bracket 131 and the second bracket 132 and improve the cutting accuracy.

[0058] Reference Figure 1The sliding mechanism 2 includes a slide rail 21 and a first drive assembly 22. The slide rail 21 is disposed at the top of the support base 11 and extends along the length of the support base 11. The cutting table 12 is slidably connected to the slide rail 21. The first drive assembly 22 is used to drive the cutting table 12 to reciprocate along the slide rail 21. Specifically, the first drive assembly 22 includes a first drive member 221, a lead screw 222, and several sliders 223. The first drive member 221 is used to drive the lead screw 222 to rotate. Specifically, the first drive member 221 can be any drive device capable of driving the lead screw 222 to rotate forward or backward. In this embodiment, the first drive member 221 is a servo motor, and is named the first servo motor. In this embodiment, a first servo motor is disposed at one end of the inner side of one of the support seats 11. The driving end of the first servo motor faces the other end of the support seat 11 and is connected to a lead screw 222. A lead screw 222 is also disposed on the inner side of the other support seat 11. The ends of the two lead screws 222 away from the first servo motor are connected to each other for transmission via a linkage rod. Two bearing seats 111 are disposed on the inner side of the support seat 11. The lead screw 222 passes through the two bearing seats 111 and is rotatably connected to the bearing seats 111. The lead screw 222 is parallel to the slide rail 21. A slider 223 is sleeved on the lead screw 222 between the two bearing seats 111 and is threadedly connected to the lead screw 222. The slider 223 is fixedly connected to the side of the cutting table 12 away from the support frame 13. Thus, when the first servo motor drives the lead screw 222 to rotate, the lead screw 222 can drive the slider 223 to reciprocate along the length direction of the lead screw 222, thereby driving the cutting table 12 to reciprocate along the direction of the slide rail 21.

[0059] Reference Figure 1 The cutting mechanism 3 includes a mounting base 31, a second drive assembly 32, and a cutting assembly 33. The mounting base 31 is installed between the first bracket 131 and the second bracket 132 and can reciprocate along the length of the support frame 13 to achieve cutting. The second drive assembly 32 drives the mounting base 31 to reciprocate along the length of the support frame 13. The cutting assembly 33 is mounted on the mounting base 31 and located directly above the cutting table 12, used to cut the fiber pad on the cutting table 12.

[0060] Reference Figure 3 and Figure 4Two guide rods 134 are provided between the connecting brackets 133 at both ends of the support frame 13. The two guide rods 134 are parallel to each other and extend along the length of the support frame 13. The two guide rods 134 are respectively close to the first bracket 131 and the second bracket 132. The two ends of the mounting seat 31 are respectively sleeved on the guide rods 134 and slidably connected to the guide rods 134. In order to make the mounting seat 31 slide smoothly, the mounting seat 31 has an oil injection hole 311. The oil injection hole 311 penetrates the mounting seat 31 and communicates with the guide rods 134, so that the operator can inject lubricating oil into the oil injection hole 311 to reduce the friction between the mounting seat 31 and the guide rods 134, so that the mounting seat 31 can slide smoothly along the guide rods 134.

[0061] Reference Figure 1 and Figure 4 The second drive assembly 32 includes a second drive member 321, a first sprocket 322, a second sprocket 323, and a first chain 324. The two ends of the first chain 324 pass over the first sprocket 322 and the second sprocket 323 respectively and connect to the mounting base 31. The second drive member 321 drives the first sprocket 322 or the second sprocket 323 to rotate, and through the first chain 324, it drives the mounting base 31 to slide along the guide rod 134. Specifically, the second drive member 321 can be any drive device capable of driving the first sprocket 322 or the second sprocket 323 to rotate forward or backward. In this embodiment, the second drive member 321 is a servo motor, named the second servo motor, which is mounted on the first bracket 131. A first sprocket seat 1311 is provided on one side of the top of the first bracket 131, and a second sprocket seat 1312 is provided on the other side. The first sprocket 322 and the second sprocket 323 are respectively mounted on the first sprocket seat 1311 and the second sprocket seat 1312, and are rotatably connected to the first sprocket seat 1311 and the second sprocket seat 1312. The drive end of the second servo motor is connected to the first sprocket 322, so that the second servo motor can drive the first sprocket 322 to rotate. Chain seats 312 are provided at both ends of the mounting base 31 along the sliding direction. One end of the first chain 324 passes around the first sprocket 322 and connects to the chain seat 312 at one end of the mounting base 31, and the other end of the first chain 324 passes around the second sprocket 323 and connects to the chain seat 312 at the other end of the mounting base 31. When the second servo motor drives the first sprocket 322 to rotate forward, the mounting base 31 can slide along the guide rod 134 toward one end of the first sprocket 322 through the transmission of the second sprocket 323 and the traction of the first chain 324; when the second servo motor drives the first sprocket 322 to rotate in reverse, the mounting base 31 can slide along the guide rod 134 toward one end of the second sprocket 323 through the transmission of the second sprocket 323 and the traction of the first chain 324.

[0062] In other embodiments, the second servo motor, the first sprocket 322, and the second sprocket 323 may also be mounted on the second bracket 132. Similarly, the second servo motor can drive the second sprocket 323 to rotate.

[0063] Reference Figure 1 and Figure 5 The cutting assembly 33 includes a cutting base 331, a cutting blade 332, a third drive assembly 333, and a fourth drive assembly 334. The cutting base 331 is hinged to the mounting base 31, and the hinge axis between the cutting base 331 and the mounting base 31 is perpendicular to the sliding direction of the mounting base 31. The cutting base 331 can rotate around the hinge axis. The cutting blade 332, the third drive assembly 333, and the fourth drive assembly 334 are all mounted on the cutting base 331. The third drive assembly 333 drives the cutting blade 332 to rotate at high speed, giving the cutting blade 332 a certain cutting capability, facilitating the cutting of the fiber mat. The fourth drive assembly 334 drives the cutting base 331 to rotate downwards around the hinge axis, allowing the cutting blade 332 to press down onto the fiber mat, thus achieving cutting.

[0064] Reference Figure 5 and Figure 6 The third drive assembly 333 includes a third drive member 3331 and a first transmission rod 3332 and a second transmission rod 3333 for transmission. The third drive member 3331 is fixedly mounted on the cutting base 331, with its drive end extending vertically towards the cutting table 12. The first transmission rod 3332 and the second transmission rod 3333 are parallel to each other and pass through the cutting base 331. Specifically, the third drive member 3331 can be any drive device capable of driving the cutting blade 332 to rotate at high speed. In this embodiment, the third drive member 3331 is a servo motor, and is named the third servo motor.

[0065] Reference Figure 5 and Figure 6 The third servo motor has a first bevel gear 3334 mounted on its drive end, and a second bevel gear 3335 mounted on its first transmission rod 3332. The first bevel gear 3334 and the second bevel gear 3335 mesh with each other. A third sprocket 3336 is mounted on one end of the third transmission rod, and a fourth sprocket 3337 is mounted on one end of the second transmission rod 3333. A second chain 3338 connects the third sprocket 3336 and the fourth sprocket 3337. The end of the second transmission rod 3333 away from the fourth sprocket 3337 is connected to the cutting blade 332. Thus, the third servo motor can drive the cutting blade 332 to rotate at high speed through the first transmission rod 3332 and the second transmission rod 3333, giving the cutting blade 332 a certain cutting capability.

[0066] Reference Figure 5The fourth drive assembly 334 includes a fourth drive member 3341 and a connecting rod 3342. The fourth drive member 3341 can be any drive device that causes the cutting seat 331 to rotate downwards towards the cutting table 12. In this embodiment, the fourth drive member 3341 is a cylinder, designated as the first cylinder. Specifically, the bottom end of the first cylinder is hinged to the end of the mounting base 31 away from the hinge axis of the cutting seat 331. The telescopic end of the first cylinder is connected to the connecting rod 3342. The end of the connecting rod 3342 away from the first cylinder is hinged to the top of the third servo motor. Since the third servo motor is fixedly mounted on the cutting seat 331, when the telescopic end of the first cylinder retracts, the first cylinder can drive the third servo motor, along with the cutting seat 331, to rotate around the hinge axis via the connecting rod 3342, thereby pressing down the cutting seat 331 so that the cutting blade 332 can contact the fiber pad and cut it.

[0067] Reference Figure 1 and Figure 7 The tensioning mechanism 4 includes a tensioning component 41, a fifth driving member 42, and a sixth driving component 43. The tensioning component 41 provides tension to the fiber pad; the fifth driving member 42 drives the tensioning component 41 towards the cutting table 12, ensuring the tensioning component 41 fully presses against the fiber pad; and the sixth driving component 43 pulls the tensioning component 41 to provide tension, facilitating cutting. Specifically, the tensioning component 41 includes two roller frames 411 and two tension rollers 412. The two roller frames 411 are respectively positioned below the connecting frames 133 on both sides of the support mechanism 1. The two tension rollers 412 are parallel to each other between the two roller frames 411 and rotatably connected to them. The two tension rollers 412 are located on both sides of the cutting blade 332. When the two tension rollers 412 rotate in opposite directions, the fiber pad between them is taut, facilitating cutting by the cutting blade 332.

[0068] Reference Figure 7 and Figure 8 The fifth driving component 42 can be any driving assembly capable of driving the roller frames 411 on both sides to move up and down. In this embodiment, the fifth driving component 42 is a cylinder, named the second cylinder. The second cylinder is installed above the connecting frame 133, and the telescopic end of the second cylinder passes through the connecting frame 133 and is fixedly connected to the roller frame 411. Through the extension and retraction of the second cylinder, the roller frames 411 on both sides can drive the tension rollers 412 to reciprocate towards the cutting table 12.

[0069] Reference Figure 7 and Figure 8The sixth drive assembly 43 includes a sixth drive member 431 and a transmission gear set 432. The sixth drive member 431, through the transmission of the gear set 432, drives two tension rollers 412 to rotate in opposite directions, thereby maintaining the tension of the fiber mat. Specifically, the sixth drive member 431 can be any drive device capable of driving the gear set 432 to rotate. In this embodiment, the sixth drive member 431 is a servo motor, named the fourth servo motor. The gear set 432 is located on the side of the roller frame 411 opposite to the tension rollers 412, and one end of each of the two tension rollers 412 passes through the roller frame 411 and connects to the gear set 432. Specifically, the gear set 432 includes a driving gear 4321, two driven gears 4322, and a connecting gear 4323. The driving gear 4321 is mounted on the drive end of the fourth servo motor, and the two driven gears 4322 are respectively mounted on the two tension rollers 412. The driving gear 4321 meshes with one of the driven gears 4322, and on the other side, it meshes with the other driven gear 4322 through the connecting gear 4323. Thus, when the fourth servo motor drives the driving gear 4321 to rotate clockwise, the driving gear 4321 directly drives one of the driven gears 4322 to rotate counterclockwise, and through the connecting gear 4323, drives the other driven gear 4322 to rotate clockwise. This causes the two tension rollers 412 to rotate in opposite directions.

[0070] The implementation principle of a cutting device in Embodiment 1 of this application is as follows:

[0071] After the fiber mat is produced, it is pulled onto the cutting table 12. The power to the first servo motor is turned on, and the first servo motor drives the lead screw 222 to rotate, causing the slider 223 and the cutting table 12, which is fixedly connected to the slider 223, to slide along the length of the slide rail 21, aligning with the production direction of the fiber mat. By adjusting the speed of the first servo motor, the sliding speed of the cutting table 12 and the support frame 13 is matched with the production speed of the fiber mat. At this point, the cutting mechanism 3 is relatively stationary with respect to the fiber mat, enabling the fiber mat to be cut without stopping the machine.

[0072] When the fiber pad needs to be cut, the second cylinder first extends, driving the roller frame 411 and tension roller 412 to press down towards the cutting table 12, so that the tension roller 412 fully presses against the fiber pad. Then, the fourth servo motor is turned on, and through the transmission of the gear set 432, the two tension rollers 412 rotate in opposite directions. Through the friction between the tension rollers 412 and the fiber pad, the fiber pad pressed between the two tension rollers 412 is straightened and tightened, so that the cutting blade 332 can cut it.

[0073] After the fiber pad is stretched and tightened, the first cylinder is activated, and the third servo motor and the cutting base 331 are pulled to rotate around the hinge axis via the connecting rod 3342. At this time, the cutting base 331 and the cutting blade 332 are pressed down towards the cutting table 12, so that the cutting blade 332 can cut the fiber pad. The third servo motor is activated, and through the first transmission rod 3332 and the second transmission rod 3333, the cutting blade 332 is driven to rotate at high speed, so that the cutting blade 332 has a certain cutting ability. Finally, the second servo motor is activated, and through the traction of the first chain 324, the mounting base 31 and the cutting mechanism 3 mounted on the mounting base 31 slide along the direction of the guide rod 134, so that the high-speed rotating cutting blade 332 cuts the fiber pad.

[0074] After cutting, the first cylinder lifts the third servo motor and the cutting seat 331, moving the cutting blade 332 away from the cutting table 12. The second cylinder retracts, driving the roller frame 411 and tension roller 412 away from the cutting table 12 to prevent affecting the subsequent production of fiber mats. Finally, the first servo motor drives the lead screw 222 to reverse, returning the slider 223 and support mechanism 1 to their original positions before cutting, facilitating the next cut.

[0075] Example 2

[0076] This application discloses a cutting device in Embodiment 2. The difference between Embodiment 2 and Embodiment 1 is the different tensioning mechanism 4.

[0077] Reference Figure 9 and Figure 10The tensioning mechanism 4 includes a second tensioning component 44 and a seventh driving component 45. The second tensioning component 44 is used to apply a certain tension to the fiber pad. The seventh driving component 45 is used to drive the second tensioning component 44 to reciprocate towards the cutting table 12. Specifically, the second tensioning component includes two hinge seats 441, two pressure rods 442, and a hinge rod 443 connecting the hinge seats 441 and the pressure rods 442. The two hinge seats 441 are respectively located below the connecting frames 133 on both sides of the support mechanism 1. The two pressure rods 442 are arranged parallel between the two hinge seats 441 and are located on both sides of the cutting blade 332. One end of the hinge rod 443 is hinged to the hinge seat 441, and the other end of the hinge seat 441 is hinged to the end of the pressure rod 442. A sliding rod 444 is connected between the two pressure rods 442, and the sliding rod 444 is slidably connected to the pressure rod 442, so that the pressure rod 442 can slide along the sliding rod 444. Limit blocks 4441 are provided at both ends of the sliding rod 444 to prevent the slider 223 from sliding out from both ends of the sliding rod 444. The length of the sliding rod 444 is greater than the farthest distance between the two pressure rods 442. When the pressure rod 442 presses against the fiber pad, the hinge seat 441 continues to press down, and the hinge rod 443 will push the two pressure rods 442 and the fiber pad pressed by the pressure rods 442 towards both sides of the sliding rod 444, thereby straightening the fiber pad between the two pressure rods 442 for easy cutting. A tension spring 445 is provided between the two pressure rods 442. Specifically, the tension spring 445 is wound around the sliding rod 444 between the two pressure rods 442. One end of the tension spring 445 is connected to one pressure rod 442, and the other end is connected to the other pressure rod 442. When the hinge seat 441 rises, the tension spring 445 can restore the two pressure rods 442 to their original position for easy cutting next time.

[0078] Reference Figure 10 The seventh driving component 45 can be any driving device capable of driving the second tensioning component 44 to reciprocate towards the cutting table 12. In this embodiment, the seventh driving component 45 is a cylinder, named the third cylinder. The third cylinder is installed above the connecting frame 133, and the telescopic end of the third cylinder passes through the connecting frame 133 and is fixedly connected to the hinge seat 441. Thus, through the extension and retraction of the third cylinder, the hinge seats 441 on both sides can drive the pressure rod 442 to reciprocate towards the cutting table 12 via the hinge rod 443.

[0079] Reference Figure 11 In order to increase the friction between the pressure bar 442 and the fiber pad and to make the fiber pad more taut, an anti-slip pad 4421 is provided on the side of the pressure bar 442 facing the cutting table 12. The anti-slip pad 4421 is provided with several anti-slip particles 4422 to prevent the pressure bar 442 from slipping on the fiber pad and causing the fiber pad to fail to maintain a taut state during cutting.

[0080] The implementation principle of a cutting device in Embodiment 2 of this application is as follows:

[0081] When the third cylinder extends, the hinge seat 441 drives the two pressure rods 442 to move toward the cutting table 12 via the hinge rod 443. After the pressure rods 442 fully press against the fiber pad, the third cylinder continues to extend, and the hinge seat 441 continues to press down. At this time, the hinge rod 443 pushes the two pressure rods 442 toward the two ends of the sliding rod 444, and the two pressure rods 442 slide in opposite directions, so that the fiber pad pressed between the two pressure rods 442 is stretched and tightened. At this time, the fiber pad has a certain tension, which makes it easier for the subsequent cutting blade 332 to cut it.

[0082] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this specific embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
