Description

Technical Field

[0001] The present application relates to the field of composite material shearing, and in particular to a fiber fixed-length shearing device and a shearing method thereof. Background Art

[0002] Fiber-related experiments usually require fibers of a specific length. In related technologies, guillotine cutters and parallel knife cutters are commonly used to cut fibers to a fixed length.

[0003] Among them, the guillotine cutter is widely used in many scenarios due to its simple structure and low cost. However, it has significant defects. It is not well adapted to the fibers to be cut and cannot meet the requirements of high-precision fixed-length shearing, resulting in uneven lengths of fiber bundles after cutting, making it difficult to meet the fixed-length standards required for the experiment.

[0049] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0050] Fiber-related experiments usually require fibers of a specific length. In related technologies, guillotine cutters and parallel knife cutters are commonly used to cut fibers to a fixed length.

[0051] Among them, the guillotine cutter is widely used in many scenarios due to its simple structure and low cost. However, it has significant defects. It is not well adapted to the fibers to be cut and cannot meet the requirements of high-precision fixed-length shearing, resulting in uneven lengths of fiber bundles after cutting, making it difficult to meet the fixed-length standards required for the experiment.

[0052] Compared with the guillotine cutter, the parallel blade cutter has higher cutting accuracy and can better meet the needs of precise shearing. However, it also has its own shortcomings, such as complex equipment structure, large capital investment, and due to its structural characteristics, it cannot be smoothly integrated into the automatic conveyor line for actual use, which to a certain extent limits its application in experimental process automation.

[0053] From the above, it can be determined that the existing fiber shearing machines are difficult to meet the needs of precision fixed-length shearing, which affects the experimental results.

[0054] To solve the above problems, the present application provides a fiber fixed-length cutting device including a base. The base serves as the basic supporting component of the entire device, which can be used as an operating platform and can stably install other components to ensure that the device as a whole remains stable during the cutting process and avoid affecting the cutting accuracy due to factors such as shaking.

[0055] In such Figure 1 As shown, the base 1 of the fiber cutting-to-length device includes a table 11 and a plurality of supporting legs 12. The table 11 is in a plate shape, and the plurality of supporting legs 12 are connected to the lower surface of the table 11 for supporting the table 11. A through slot is provided on the table 11, and the through slot can be used to set other components of the fiber cutting-to-length device (such as the cutting part 3).

[0056] like Figure 1-2As shown, the fiber fixed length shearing device also includes a clamping part 2, which includes a connected clamping claw mechanism 21 and a first driving mechanism 22. The first driving mechanism 22 is arranged on the base 1, and the first driving mechanism 22 is used to drive the clamping claw mechanism 21 along the Figure 1 The clamping mechanism 21 moves in the x-direction and the z-direction, so that the clamping mechanism 21 moves between the first position and the second position, and the clamping mechanism 21 is used to clamp the fiber 8.

[0057] When the clamping mechanism 21 is in the first position, the clamping mechanism 21 is located in the mounting groove 311 and clamps the fiber 8 to complete the clamping action. When the clamping mechanism 21 is in the second position, the clamping mechanism 21 is located outside the mounting groove 311 and releases the fiber 8 to complete the release action. Figure 1 When the clamp mechanism 21 moves to the second position in the x direction, it moves away from the mounting slot 311 and releases the fiber. In some embodiments, in order to prevent other components from affecting the movement of the clamp mechanism 21, the clamp mechanism 21 first moves along the first position after clamping the fiber 8. Figure 1 The clamping mechanism 1 moves in the z direction to move away from the shearing portion 3, and then the clamping mechanism 21 is controlled to move in the x direction. Figure 1 When the x-coordinate and y-coordinate of the first position are the same as those of the second position, the first position moves along the z-direction until it reaches the second position.

[0058] The clamping mechanism 21 can be accurately placed at the first position and the second position.

[0059] In one embodiment, an upper limit block is provided on the base, for example, two limit blocks are provided, respectively recorded as a first limit block and a second limit block, when the clamping mechanism 21 moves to the first position, the first limit block limits the movement of the clamping mechanism 21, so that the clamping mechanism 21 can accurately fall at the first position. When the clamping mechanism 21 moves to the second position, the second limit block limits the movement of the clamping mechanism 21, so that the clamping mechanism 21 can accurately fall at the second position.

[0060] In other embodiments, an encoder may be provided to control the first driving mechanism 22 to stop moving according to pulses, so as to accurately land at the first position and the second position.

[0061] The clamping mechanism 21 is a component that directly contacts the fiber 8 and implements the clamping action. The clamping mechanism 21 can gently grasp and firmly clamp the fiber 8, ensuring that the surface of the fiber 8 will not be scratched or damaged, and that the fiber 8 will not slip during the clamping process.

[0062] like Figure 1 and Figure 3As shown, the fiber fixed-length shearing device also includes a shearing section 3, which is used to shear fibers. The shearing section 3 includes a mounting disc 31, two cutters 32 and two trigger structures 33. The mounting disc 31 is rotatably connected to the base 1. The mounting disc 31 forms a mounting groove 311. The mounting groove 311 is formed by a portion of the outer peripheral surface of the mounting disc being recessed radially inward, for example, by cutting. The two cutters 32 are arranged on the mounting disc 31, and the two cutters 32 are movably arranged in the mounting groove 311. The two trigger structures 33 are arranged on the base 1. The two trigger structures 33 correspond to the two cutters 32 one by one. When the mounting disc 31 rotates to a preset angle, the cutters 32 can touch the trigger structures 33 and approach each other under the action of the trigger structures 33 to shear the fiber 8 located between the two cutters 32.

[0063] In such Figure 1 In the embodiment shown, the axial direction of the installation wheel disc 31 is Figure 1 The y direction is the same, and the installation wheel 31 is located at the through groove of the table 11, which is manifested as one part of the installation wheel 31 is located above the table 11, and the other part is located below the table 11, ensuring that the fiber 8 transmitted in the horizontal direction can be located between the two cutters 32, while making full use of the space below the table 11, which is conducive to lowering the setting height of the table 11 and facilitating the operation and inspection of technicians. The two trigger structures 33 are both located on the table 11, and along Figure 1 In the y direction, the two trigger structures 33 are respectively located on both sides of the mounting wheel 31. When the mounting wheel 31 rotates, the two cutters 32 are driven to rotate. When the two cutters 32 are located above the table 11 and cooperate with the two trigger structures 33, the fibers 8 are cut.

[0064] Among them, Figure 4 As shown, when the clamping mechanism 21 is in the first position, the clamping mechanism 21 is located in the mounting groove 311 and clamps the fiber 8 to complete the clamping action. When the clamping mechanism 21 is in the second position, the clamping mechanism 21 is located outside the mounting groove 311 and releases the fiber 8 to complete the releasing action. The connecting line of the first position and the second position is perpendicular to the axial direction of the mounting wheel 31 (as shown in FIG. Figure 1 In the embodiment shown, the line connecting the first position and the second position is the same as the x direction); when the mounting wheel 31 rotates along the preset direction, the clamping action, the cutting action and the releasing action are completed in sequence. Figure 4 In the illustrated embodiment, the mounting wheel 31 rotates counterclockwise.

[0065] The fiber 8 is located on the base 1 and rests on the portion of the mounting wheel 31 located above the base 1. The length between the cutting position and the second position is the fixed length of the fiber 8, that is, the length of the fiber 8 to be cut. Before starting the device, the end of the fiber 8 can be manually moved to the second position. After starting the device, the mounting wheel 31 is moved along the preset direction. When the mounting wheel 31 moves to the first preset angle, the clamping mechanism 21 is located at the first position under the drive of the first driving mechanism 22, and the clamping mechanism 21 is located in the mounting groove 311 when it is in the first position and clamps the fiber 8. The action of the clamping mechanism 21 clamping the fiber 8 at the first position is recorded as the clamping action. After the clamping mechanism 21 completes the first action, when the mounting wheel 31 moves to the second preset angle, the two cutters 32 complete the cutting action at the cutting position. Then, when the mounting wheel 31 moves to the third preset angle, the clamping mechanism 21 is located at the second position outside the mounting groove 311 to release the fiber 8 to complete the release action. The above-mentioned clamping action, cutting action and release action are completed in sequence to cut the fixed-length fiber 8.

[0066] In the present application, the clamping mechanism 21 and the first driving mechanism 22 cooperate to enable the clamping mechanism 21 to accurately clamp the fiber 8 at the first position and release it at the second position. The portion of the fiber 8 between the first position and the second position is the fixed-length portion, which is then accurately cut by the tool 32 and the trigger structure 33, with high cutting efficiency and high cutting accuracy.

[0067] The present application discloses a fiber 8 fixed-length shearing device, comprising a base 1, a clamping part 2 and a shearing part 3, wherein the clamping part 2 comprises a connected clamping mechanism 21 and a first driving mechanism 22, wherein the first driving mechanism 22 is arranged on the base 1, and the first driving mechanism 22 is used to drive the clamping mechanism 21 to move between a first position and a second position, and the clamping mechanism 21 is used to clamp the fiber 8. The shearing part 3 comprises a mounting wheel 31 and two cutters 32 arranged on the mounting wheel 31, and two trigger structures 33 arranged on the base 1, wherein the mounting wheel 31 is rotatably connected to the base 1, and a mounting groove 311 is arranged on a part of the outer periphery of the mounting wheel 31, wherein the mounting groove 311 is a part of the outer periphery of the mounting wheel 31 which is concavely arranged toward the radial inner side, and the two cutters 32 are movably arranged in the mounting groove 311, and the two trigger structures 33 correspond to the two cutters 32 one by one, and the two trigger structures 33 are used to make the two cutters 32 approach each other at the cutting position to cut the fiber 8 and complete the cutting action. Among them, when the clamping mechanism 21 is in the first position, the clamping mechanism 21 is located in the mounting groove 311 and clamps the fiber 8 to complete the clamping action. When the clamping mechanism 21 is in the second position, the clamping mechanism 21 is located outside the mounting groove 311 and releases the fiber 8 to complete the releasing action. The line connecting the first position and the second position is perpendicular to the axial direction of the mounting wheel 31. When the mounting wheel 31 rotates along the preset direction, the clamping action, the cutting action and the releasing action are completed sequentially.

[0068] In some embodiments, Figure 3 As shown, the two cutters 32 are provided with inclined surfaces 321 at positions away from each other. The cutters 32 of the present application are moved closer to each other under the cooperation of the inclined surfaces 321 and the trigger structure 33, so as to facilitate cutting of the fiber 8.

[0069] In some embodiments, the cutter 32 includes a connecting block and a blade, wherein one end of the connecting block is hinged at the mounting groove 311, the hinge axis of the connecting block is in the same radial direction as the mounting wheel 31, and the inclined surface 321 is provided on the connecting block. The blade can be provided on the connecting block by bolts, so as to facilitate the replacement of the blade.

[0070] exist Figure 1 In the embodiment shown, the trigger structure 33 is cylindrical in shape, and the length direction of the trigger structure 33 is the same as the z direction. When the mounting wheel 31 rotates, the two cutters 32 are driven to rotate. When the two cutters 32 approach the two trigger structures 33, the trigger structure 33 first contacts the inclined surface 321 on the cutter 32, and the trigger structure 33 rolls along the inclined surface 321. The inclined surface 321 and the trigger structure 33 cooperate to limit the cutter 32, so that the cutters 32 approach each other to cut the fiber 8 at the cutting position.

[0071] In other embodiments, the trigger structure 33 may also be a block-shaped object, and a contact surface that cooperates with the inclined surface 321 of the tool 32 is provided on the trigger structure 33 of the block. The contact surface is inclined. When the mounting wheel 31 rotates, the two tools 32 are driven to rotate. When the two tools 32 approach the two trigger structures 33, the contact surface of the trigger structure 33 contacts the inclined surface 321 of the tool 32 and slides with each other. The cooperation between the inclined surface 321 and the contact surface makes the tools 32 approach each other to cut the fiber 8 at the cutting position.

[0072] In some other embodiments, the tool 32 and the trigger structure 33 are both magnets, and the contacting sides of the tool 32 and the trigger structure 33 have the same magnetic poles.

[0073] In one embodiment, the sides where the cutter 32 and the trigger structure 33 are in contact are both South Pole or both North Pole, so that when the mounting wheel 31 drives the cutter 32 to rotate and approach the trigger structure 33, the like poles repel each other and cause the cutter 32 to move away from the trigger structure 33, which is manifested as the two cutters 32 approaching each other to cut the fiber 8. Moreover, since the sides where the two cutters 32 are close to the corresponding contact mechanisms are at the same pole, the sides where the two cutters 32 are close to each other are also at the same pole. Therefore, when the two cutters 32 are at a position away from the trigger structure 33, the two cutters 32 move away from each other, so that there is a gap between the two cutters 32 for the fiber 8 to pass through.

[0074] The tool 32 and the trigger structure 33 of the present application are configured as magnets, which can avoid wear of the tool 32 and the trigger structure 33 and increase their service life.

[0075] In some embodiments, Figure 3 As shown, the installation wheel disc 31 is provided with a guide groove 312, which is formed by the inward depression of the circumferential side wall of the installation wheel disc 31, and both ends of the guide groove 312 are connected to the installation groove 311, and the guide groove 312 is located in the middle of the outer circumference of the installation wheel disc 31. The distance between the side of the installation groove 311 close to the central axis of the installation wheel disc 31 and the central axis of the installation groove 311 is a first distance, and the distance between the side of the guide groove 312 close to the central axis of the installation wheel disc 31 and the central axis of the installation groove 311 is a second distance, and the first distance is less than or equal to the second distance.

[0076] The guide groove 312 is provided to assist the fiber 8 to be precisely positioned, so that the fiber 8 can move along the guide groove 312, and avoid deviation and misalignment of the fiber 8, which may affect the precise shearing. The first distance is less than or equal to the second distance, so that when the fiber 8 passes through the installation groove 311, both ends of the fiber 8 are placed on the guide groove 312, that is, the fiber 8 is suspended in the installation groove 311, so that the clamping mechanism 21 can clamp the fiber 8 more accurately, providing a stable operation premise for the subsequent cutting action, and improving the stability of the device.

[0077] In some embodiments, Figure 3 As shown, the shearing section 3 further includes a return spring 34, which is disposed between the two cutters 32, and the two ends of the return spring 34 are respectively in contact with the two cutters 32. The arrangement of the return spring 34 causes the two cutters 32 to be subjected to an elastic force moving away from each other, and when the fiber 8 does not need to be cut, the gap between the two cutters 32 facilitates the fiber 8 to pass through.

[0078] In some embodiments, Figure 3 As shown, the shearing portion 3 further includes a rotating shaft 35 and a first driving motor 36. The rotating shaft 35 is coaxially connected with the mounting wheel disc 31. The rotating shaft 35 is arranged on the base 1 through a bearing seat 37. The first driving motor 36 is arranged on the base 1. The output end of the first driving motor 36 is connected to the rotating shaft 35 to drive the rotating shaft 35 to rotate. The first driving motor 36 drives the rotating shaft 35 to rotate, and the rotating shaft 35 drives the mounting wheel disc 31 to rotate. The speed of the mounting wheel disc 31 can be controlled by controlling the speed of the first driving motor 36.

[0079] The rotation of the mounting wheel 31 can be controlled by the first driving motor 36 , and the rotating shaft 35 and the bearing seat 37 can stably mount the rotating shaft 35 on the base 1 , thereby improving the reliability and service life of the equipment.

[0080] In some embodiments, Figure 1-2 As shown, the first driving mechanism 22 includes a first guide rod 221, a first slider 222 and a moving assembly 223. The first guide rod 221 is arranged on the base 1, and the direction of the first guide rod 221 is parallel to the direction of the line connecting the first position and the second position. Figure 1 In the embodiment shown, the direction of the first guide rod 221 is the x direction. The first slider 222 is slidably disposed on the first guide rod 221. The first end of the moving component 223 is connected to the first slider 222, and the second end of the moving component 223 is connected to the clamping mechanism 21 to drive the clamping mechanism 21 to move along the extending direction perpendicular to the first guide rod 221, such as Figure 1 In the embodiment shown, the moving assembly 223 is used to drive the clamping mechanism 21 to move along the z direction. The first slider 222 slides along the first guide rod 221, and the first slider 222 drives the moving assembly 223 to slide, so that the moving assembly 223 moves along the direction extending from the first guide rod 221 under the drive of the first slider 222. Figure 1 In the embodiment shown, the moving assembly 223 moves along the x direction under the drive of the first slider 222, so that the moving assembly 223 drives the clamping mechanism 21 to move along the x direction. Figure 1 The moving assembly 223 itself can drive the clamping mechanism 21 to move along the extending direction perpendicular to the first guide rod 221, such as Figure 1 In the illustrated embodiment, the moving assembly 223 can drive the clamping mechanism 21 to move along the z direction. Therefore, the clamping mechanism 21 can move along the x direction and the z direction.

[0081] By setting the first slider 222, the clamping mechanism 21 can move along the extension direction of the first guide rod 221. By setting the moving component 223, the clamping mechanism 21 can move along the extension direction perpendicular to the first guide rod 221. The clamping mechanism 21 can be located at any position of the base 1 to facilitate the movement of the clamping mechanism 21.

[0082] In some embodiments, such as Figure 1-2 As shown, the first guide rod 221 is configured as a first rack, the first rack is disposed on the base 1, the first slider 222 is configured as a first gear, the first gear is meshed with the first rack, the moving assembly 223 includes a frame and a telescopic rod, the first gear is rotatably disposed on the first end of the frame, the first end of the telescopic rod is disposed on the second end of the frame, the extension direction of the telescopic rod is perpendicular to the extension direction of the first guide rod 221 and the axial direction of the mounting wheel 31, Figure 1 In the embodiment shown, the extension direction of the telescopic rod is the z direction, and the second end of the telescopic rod is connected to the clamping mechanism 21. The first driving mechanism 22 is further provided with a second driving motor 224, which is provided on the frame, and the output end of the second driving motor 224 is connected to the gear, and the second driving motor 224 drives the gear to rotate, and the gear rotation is manifested as moving along the first rack, and the gear drives the frame to move along the first rack.
