The driving device body is a cylinder. The telescopic end of the cylinder is connected to the frame 1 to drive the frame 1 along the Figure 1 Reciprocating motion is performed in the vertical direction shown in FIG.

[0027] Two clamping assemblies 2 are installed on the frame 1. Each clamping assembly 2 can compress four yarn bundle bodies delivered from the corresponding steering device body to avoid the phenomenon of the yarn bundle body being pulled back due to the tension force generated by the yarn bundle body during the yarn laying process, thereby affecting the yarn laying effect of the device.

[0028] The re-feeding assembly 3 is installed on the frame 1 through a movable bolt and is located above and below the clamping assembly 2.

[0032] Specifically, the heating component 6 heats the cut filament bundle body laid on the mold body to be laid so as to maintain the filament bundle body at an appropriate temperature, thereby ensuring that the filament bundle body can be evenly and tightly fitted with the surface to be laid of the mold body to be laid.

[0033] like Figure 1 and Fig. 9 As shown, in a specific implementation, it also includes: The pressing roller assembly 7 is connected to the frame 1 and is located on one side of the combing assembly 5. The pressing roller assembly 7 is used to press the cut filament bundle body laid on the mold body to be laid.

[0034] Specifically, the pressing roller assembly 7 is used to press the cut tow body laid on the mold body to be laid, so that the tow body can be evenly and tightly fitted with the surface to be laid of the mold body to be laid.

[0035] like Figure 1-Figure 3 As shown, in a specific implementation, each of the clamping components 2 includes: A first bracket 21 and a second bracket 22 are stacked, wherein a passage for the tow body to pass through is formed between the first bracket 21 and the second bracket 22, and the first bracket 21 is connected to the frame 1; A first rotating portion 23 is rotatably disposed on the first bracket 21 around a first direction, and a portion of the first rotating portion 23 facing the second bracket 22 is exposed in the channel; A second rotating portion 24 is rotatably disposed on the second bracket 22 around the first direction, and a portion of the second rotating portion 24 facing the first bracket 21 is exposed in the channel; The first rotating part 23 and the second rotating part 24 have a first working state and a second working state. In the first working state, the first rotating part 23 and the second rotating part 24 exposed in the channel rotate toward each other to drive the tow body passing through the channel to move forward. In the second working state, the first rotating part 23 exposed in the channel maintains a stationary state to block the tow body passing through the channel from moving forward. The first direction is perpendicular to a stacking direction of the first bracket 21 and the second bracket 22 .

[0036] Specifically, Figure 2As shown in , the first direction is a stacking direction perpendicular to the first bracket 21 and the second bracket 22, that is, the first direction is a horizontal direction, and the first bracket 21 and the second bracket 22 are connected in a detachable manner, for example, by bolts, and the first bracket 21 is also used to be detachably connected to the main body of the wire placing head frame 1, for example, by bolts, and a first rotating portion 23 is provided on the first bracket 21, and a second rotating portion 24 is provided on the second bracket 22, and the first rotating portion 23 is opposite to the second rotating portion 24, and the part of the first rotating portion 23 facing the second bracket 22 is exposed in the channel, and the part of the second rotating portion 24 facing the first bracket 21 is exposed in the channel, and the channel is a channel for the filament bundle body to pass through. In the first working state, the first rotating portion 23 and the second rotating portion 24 exposed in the channel rotate towards each other to drive the filament bundle body passing through the channel to move forward; in the second working state, the first rotating portion 23 exposed in the channel maintains a stationary state to block the movement of the filament bundle body passing through the channel, wherein, as Figure 2 and Figure 3 As shown in , the traveling direction of the tow body in the channel is perpendicular to the first direction. For example, if the channel is longitudinal, that is, from top to bottom or from bottom to top, then the first direction is transverse, that is, from left to right or from right to left.

[0037] The clamping assembly 2 provided in the embodiment of the present invention can avoid the phenomenon that the yarn bundle will generate tension and cause the yarn bundle to be pulled back by performing a unidirectional rotation on the first bracket 21 through a first rotation, thereby effectively solving the technical problems existing in the prior art.

[0038] like Figure 1-Figure 3 As shown, in a specific implementation, the first bracket 21 has a first hollow along the second direction, and at least one group of recessed portions is provided on a side surface of the first bracket 21 opposite to the second bracket 22, each group of recessed portions includes two grooves, the two grooves are arranged along the third direction, and the first hollow is located between the two grooves; The second bracket 22 has a second hollowing out along the second direction, the first hollowing out is aligned with the second hollowing out, and at least one group of protrusions corresponding to at least one group of recessed portions is arranged on a side surface of the second bracket 22 opposite to the first bracket 21, the protrusions and the recessed portions correspond one to one in the second direction, each group of the protrusions includes two protrusions, the two protrusions are arranged along the third direction, and the second hollowing out is located between the two protrusions, the protrusion located on the same side of the first hollowing out and the second hollowing out is embedded in the groove to enclose a receiving space with two openings opposite to each other along the third direction, and the two corresponding receiving spaces along the third direction form a channel, the part of the first rotating part 23 facing the second bracket 22 is exposed in the channel through the first hollowing out, and the part of the second rotating part 24 facing the first bracket 21 is exposed in the channel through the second hollowing out; the second direction is the stacking direction of the first bracket 21 and the second bracket 22, and the third direction is perpendicular to the first direction and the second direction.

[0039] Specifically, the first hollowing is used to expose the first rotating part 23 mounted on the first bracket 21 toward the second bracket 22, so that the first rotating part 23 and the second rotating part 24 can rotate toward each other to drive the tow body passing through the channel to move forward.

[0040] The second hollowing is used to expose the second rotating part 24 mounted on the second bracket 22 toward the first bracket 21, so that the second rotating part 24 can rotate in coordination with the first rotating part 23 to drive the tow body passing through the channel to move forward.

[0041] Two grooves are provided on a surface of the first bracket 21 opposite to the second bracket 22. The two grooves are located on both sides of the first hollowing and are arranged along the third direction. Figure 3 As shown in the figure, the third direction is the vertical direction in the figure, and the two grooves located in the same vertical direction are a group of recessed portions. The first bracket 21 is provided with at least one group of recessed portions. If the number of recessed portions is two or more, the multiple groups of recessed portions are arranged along the first direction (such as Figure 2 and Figure 3 As shown in the figure, the first direction is the lateral direction in the figure) and is arranged at intervals, wherein the number of groups of the recessed portions matches the number of groups of the filament bundle bodies and corresponds one to one.

[0042] Two protrusions are provided on the surface of the second bracket 22 opposite to the first bracket 21, the two protrusions are located on both sides of the second hollow, and the two protrusions are arranged along the third direction, and the two protrusions located in the same vertical direction are a group of protrusions. At least one group of protrusions is provided on the second bracket 22. If the number of protrusions is two or more, the multiple groups of protrusions are arranged at intervals along the first direction, wherein the number of groups of protrusions is the same as the number of groups of recessed parts, and corresponds one to one.

[0043] A group of recessed parts and a group of raised parts are matched and plugged, that is, a protrusion is inserted into a groove. The following is an example of a group of recessed parts and a group of raised parts plugged together: When the first bracket 21 is connected to the second bracket 22, the protrusion located on the same side of the first hollow and the second hollow is inserted into the groove on the same side to enclose a accommodating space with two openings opposite to each other along the third direction. The two accommodating spaces are connected by the first hollow and the second hollow, and a channel for the filament bundle body to pass through is formed. The number of channels is the same as the number of filament bundle bodies and corresponds one to one. The part of the first rotating part 23 facing the second bracket 22 is exposed in the channel through the first hollow, and the part of the second rotating part 24 facing the first bracket 21 is exposed in the channel through the second hollow.

[0044] The first rotating part 23 includes a rotating shaft and at least one rotating wheel.

[0045] Pressure rollers are arranged at both ends of the rotating shaft. The pressure rollers are detachably connected to the rotating shaft via bolts, and each pressure roller is detachably connected to the first support via bolts.

[0046] The axial extension direction of the rotating shaft is the same as the first direction. If the number of rotating wheels is two or more, the multiple rotating wheels are arranged in sequence along the axial extension direction of the rotating shaft. The number of rotating wheels is the same as the number of filament bundle bodies and corresponds one to one.

[0047] The rotating wheel is connected to the rotating shaft in a one-way rotation through a one-way bearing. The one-way rotation of the rotating wheel can achieve the effect of locking and limiting, avoiding the phenomenon that the tow will generate tension and cause the tow to be pulled back, effectively solving the technical problems existing in the prior art. The rotating wheel passes through the first hollow on the first bracket 21, so that the part of the rotating wheel facing the second bracket 22 is exposed in the channel.

[0048] The second rotating part 24 includes: at least one rotating wheel, the rotating wheel is rotatably connected to the second hollow, the number of the rotating wheels is the same as the number of the tow bodies, and they correspond one to one, the rotating wheel is rotatably connected to the second hollow through a rotating shaft, and the rotating wheel can also achieve the effect of rotatably connecting to the second hollow through other auxiliary structures. In addition, the part of the rotating wheel facing the first bracket 21 is exposed through the second hollow.

[0049] The number of the rotating wheels is adapted to the number of the rotating wheels and corresponds one to one. When the number of the rotating wheels is two or more, the arrangement of the rotating wheels is the same as the arrangement of the rotating wheels.

[0050] When the rotating wheel cooperates with the rotating wheel in the first working state, the rotating wheel exposed in the channel and the rotating wheel corresponding to the rotating wheel rotate towards each other to drive the yarn bundle body passing through the channel to move forward; when in the second working state, the rotating wheel exposed in the channel maintains a stationary state to block the movement of the yarn bundle body passing through the channel.

[0051] In the present application, the rotating wheel is installed on the second bracket 22 through a support frame, one rotating wheel is adapted to one support frame, and each support frame has a straight section and a raised section, wherein the straight section is in the shape of an "I", and the raised section is in the shape of an "I", the straight section is connected to the raised section, and the straight section and the raised section are perpendicular to each other, and the connection between the raised section and the straight section is located in the middle of the straight section, and the end of the raised section away from the straight section is rotatably connected to the rotating wheel.

[0052] The straight section is connected to a side of the second bracket 22 away from the first bracket 21 along the third direction, so that an end of the raised section away from the straight section passes through the second hollow and faces the corresponding rotating wheel.

[0053] The end of the raised section away from the straight section is provided with a rotating shaft, a rotating wheel is sleeved on the rotating shaft, and the rotating wheel is rotatably connected to the rotating shaft. The rotating shaft and the raised section are connected in a detachable manner, such as bolt connection. The raised section and the straight section are cast into an integrated structure by an integrated casting method.

[0054] Two clamping cylinders 25, each clamping cylinder 25 is connected to the frame 1 through a mounting seat 61, and the connection method can be detachable, such as bolt connection, the output ends of the two clamping cylinders 25 are connected to the second bracket 22, the output ends of the two clamping cylinders 25 are symmetrical relative to the second hollow of the second bracket 22, and the telescopic ends of the two clamping cylinders 25 move synchronously. The telescopic end of each clamping cylinder 25 is detachably connected to the second bracket 22, such as bolt connection, plug-in or inlay connection, and this structural design can facilitate the later maintenance of technicians.

[0055] The present application provides a method for movably connecting a support frame and a second support 22, that is, one end of the straight section of the support frame is hinged to the second support 22 through a pin, and the other end of the straight section is connected to the second support 22 through a bolt, and a spring 26 is arranged between the bolt and the straight section.

[0056] The number of springs 26 is the same as the number of support frames, and they correspond one to one. The springs 26 are used to provide a rebound force so that the rotating wheel and the corresponding rotating wheel press the tow body between them to achieve the effect of fixing the position of the tow body. It should be noted that fixing the position of the tow body does not limit whether the tow body can move in the corresponding channel. What is fixed is the moving track of the tow body in the corresponding channel to prevent the moving track of the tow body in the corresponding channel from being offset or deviating from the corresponding rotating wheel and the rotating wheel.

[0057] The purpose of the hinge is to facilitate the support frame to move away from or close to the second bracket 22 with the movement of the clamping cylinder 25, and to compress or release the corresponding tow body between the rotating wheel and the corresponding rotating wheel.

[0058] When the driving mechanism drives the second bracket 22 to retract in the direction of the first bracket 21, the support frame moves in the direction away from the first bracket 21, and the spring 26 is compressed. Under the action of the elastic force, the compressed spring 26 provides a rebound force for the corresponding rotating wheel, so that the rotating wheel and the corresponding rotating wheel press the yarn bundle body between the two; when the driving mechanism drives the second bracket 22 to stretch in the direction of the first bracket 211, the support frame and the second bracket 22 approach each other, and the spring 26 slowly returns to its original state as the support frame and the second bracket 22 approach each other, and gradually reduces the resistance force on the corresponding rotating wheel to release the state in which the rotating wheel and the corresponding rotating wheel press the yarn bundle body between the two. This structural design enables the device to control the yarn bundle body well and avoid the problem of position change of the yarn bundle body.

[0059] like Figure 1 and Figure 4 As shown, in a specific implementation, the re-sending component 3 includes: A driving motor 31, a first roller assembly 32, a second roller assembly 33, a first rotating wheel assembly 34 and a second rotating wheel assembly 35; The driving motor 31 is fixed on the frame 1, and the output end of the driving motor 31 is transmission-connected to the first roller assembly 32. The first roller assembly 32 and the second roller assembly 33 are arranged in parallel. The second roller assembly 33 rotates following the first roller assembly 32. A first rotating wheel assembly 34 is arranged on one side of the first roller assembly 32, and a second rotating wheel assembly 35 is arranged on one side of the second roller assembly 33. The filament bundle body transported by the clamping assembly 2 is clamped between the first roller assembly 32 and the first rotating wheel assembly 34, and the filament bundle body transported by the clamping assembly 2 is clamped between the second roller assembly 33 and the second rotating wheel assembly 35.

[0060] Specifically, the driving motor 31 is fixed to the frame 1 by bolts, and the output end of the driving motor 31 is connected to the first roller assembly 32 through a transmission connection, so as to drive the first roller assembly 32 to rotate. The first roller assembly 32 and the second roller assembly 33 are passed through the wire laying head frame 1 to achieve a rotation effect, and the first roller assembly 32 and the second roller assembly 33 are arranged in parallel and meshed with gears to transmit the transmission, so that the second roller assembly 33 rotates with the first roller assembly 32, and the rotation directions of the two are opposite, the first roller assembly 32 rotates counterclockwise, and the second roller assembly 33 rotates clockwise.

[0061] A first rotary wheel assembly 34 is arranged on one side of the first roller assembly 32, and a second rotary wheel assembly 35 is arranged on one side of the second roller assembly 33. When several rotary wheels on the first rotary wheel assembly 34 are close to the first roller assembly 32 respectively, relying on the clamping force between the two and the counterclockwise rotation of the first roller assembly 32, the left-side bundle body is transferred downward, and the distance can be controlled to independently control the clamping force and the laying of several bundle bodies. When several rotary wheels on the second rotary wheel assembly 35 are close to the second roller assembly 33 respectively, relying on the clamping force between the two and the clockwise rotation of the second roller assembly 33, the right-side bundle body is transferred downward.

[0062] The first wheel assembly 34 and the second wheel assembly 35 can independently control four tow bodies on one side, and a total of eight tow bodies can be independently controlled on both sides. The number of wheels can be increased or decreased according to the actual composite material laying requirements, thereby changing the number of tow bodies.

[0063] The driving motor 31 comprises a motor body, a first synchronous wheel, a thrust bearing and a synchronous belt; The motor body is fixed on the frame 1 , and a first synchronous wheel and a thrust bearing are sleeved on the output shaft of the motor body. The first synchronous wheel is transmission-connected to the first roller assembly 32 via a synchronous belt.

[0064] The motor body is fixed on the frame of the wire laying head, and the first synchronous wheel and the thrust bearing are sequentially sleeved on the output shaft of the motor body. The first synchronous wheel is a component used for synchronous transmission, which is used in conjunction with the synchronous belt to transmit the rotational power to the first roller assembly 32, and the thrust bearing is used to bear the axial force to prevent the first synchronous wheel from moving in the axial direction and sliding out of the output shaft.

[0065] The first roller assembly 32 includes a first roller body, a second synchronous wheel and a first transmission gear; One end of the first roller body is sleeved with a second synchronous wheel, and the other end of the first roller body is sleeved with a first transmission gear. The first roller body is arranged in parallel with the second roller assembly 33, and the second synchronous wheel is transmission-connected with the output end of the driving motor 31. The first transmission gear drives the second roller assembly 33 to rotate. The second roller assembly 33 includes a second roller body and a second transmission gear; the second roller body is arranged in parallel with the first roller body, one end of the second roller body is meshed with the first transmission gear and connected with the second transmission gear, and the end of the first roller body close to the driving motor 31 is provided with a second synchronous wheel, and the second synchronous wheel and the output end of the driving motor 31 are connected by a synchronous belt. At this time, the driving motor 31 provides power to drive the second synchronous wheel to rotate, and then drive the first roller body to rotate counterclockwise, and the other end of the first roller body away from the driving motor 31 is provided with a first transmission gear, and the first transmission gear rotates with the first roller body and meshes with the second roller assembly 33 as a power output gear and drives the rotation, so that the second roller assembly 33 rotates clockwise to provide power for the downward transportation of the tow body.

[0066] The transmission ratio between the first transmission gear and the second transmission gear is 1:1, and the number of teeth of the first transmission gear and the second transmission gear is the same, that is, the transmission ratio is 1:1; the same transmission ratio can ensure that when switching between left and right wire laying, the wire bundle bodies on both sides can be laid evenly in turn, preventing the wire bundle bodies on both sides from descending to the pressure roller at different speeds due to different transmission ratios, resulting in uneven final laying.

[0067] The first rotating wheel assembly 34 includes a bracket, a first U-shaped bracket, a first pin shaft, a first ball pin, a first rotating wrench, a valve island, a cylinder, a water drop plate and a first rotating wheel; The bracket is arranged on the side of the first roller assembly 32, and a first U-shaped bracket is provided at both ends of the bracket. The first pin shaft is clamped in the groove of the first U-shaped bracket, one end of the first pin shaft is fixedly connected to the first ball pin, and the other end of the first pin shaft is connected to the first rotating wrench. A valve island is provided at the top of the bracket, and the valve island is pneumatically connected to several cylinders through pipelines. A teardrop-shaped plate is hinged at the output end of each cylinder, and a first rotating wheel is provided between two adjacent teardrop-shaped plates. One side of the filament bundle body is clamped between the first rotating wheel and the first roller assembly 32.

[0068] The bottom end of the bracket is in a hook shape, and the end of the water drop-shaped plate is arranged at the hook at the bottom end of the bracket.

[0069] The bracket is arranged on the side of the first roller assembly 32, and two first U-shaped brackets are welded at both ends of the bracket. The first U-shaped bracket is used to install and remove the first rotating wheel assembly 34 from the frame 1. The two first pins are respectively clamped in the grooves in the first U-shaped brackets at both ends, and can rotate in the grooves. One end of the first pin is fixedly connected to the first ball pin, which is a sphere and two cylinders welded together, and the other end of the first pin is connected to the first rotating wrench. When disassembly or installation is required, the first rotating wrench is rotated, and the first ball pin is also rotated through the first pin, and changes from a longitudinal state to a transverse state. At this time, the first rotating wrench is grasped and slid outward, and the first rotating wheel assembly 34 can be installed and removed from the wire laying head frame 1.

[0070] A valve island is arranged at the top of the bracket, and the valve island integrates multiple valves, sensors, actuators and other fluid control components in a frame 1 to achieve more efficient, compact and flexible control. The valve island pneumatically connects several cylinders through pipelines, so as to control each cylinder separately, and the output end of each cylinder is vertically hinged downward with a water drop plate. When several filament bundle bodies need to be transported downward to the pressure roller end of the laying head, the cylinder is controlled by the valve island to extend and retract, and the water drop plate will also bounce obliquely to the upper right, thereby extending the first runner arranged between two adjacent water drop plates closer to or away from the first roller assembly 32. At the same time, there is only one filament bundle body on each first runner, which realizes the control of the individual filament bundle body in the laying process, and the increased pressing force will also ensure the stability of the filament bundle body during the laying process.

[0071] The bottom end of the bracket is hook-shaped, and the end of the water drop plate is placed at the hook at the bottom end of the bracket. The hook shape is designed according to the overall structure of the wire laying machine to prevent the water drop plate from being ejected too high diagonally upward due to excessive power of the cylinder, excessive elastic force or inertia, resulting in friction between the first rotating wheel and the first roller body. The end of the water drop plate is placed at the hook at the bottom end of the bracket, and when it reaches a certain height, the water drop plate will be limited.

[0072] In an embodiment of the present invention, the second rotating wheel assembly 35 includes a support block, a second U-shaped bracket, a second pin shaft, a second ball pin, a second rotating wrench, a pneumatic push rod, a fixing plate and a second rotating wheel; The support block is arranged on the side of the second roller assembly 33, and a second U-shaped bracket is provided at both ends of the support block. The second pin shaft is clamped in the groove of the second U-shaped bracket, one end of the second pin shaft is fixedly connected to the second ball pin, and the other end of the second pin shaft is connected to the second rotating wrench. A plurality of pneumatic push rods are fixedly connected to the side of the support block away from the second roller assembly 33, and a fixed plate is hinged at the output end of each pneumatic push rod, and a second rotating wheel is provided between two adjacent fixed plates, and the tow body is clamped between the second rotating wheel and the second roller assembly 33.

[0073] The disassembly part of the second rotating wheel assembly 35 is the same as that of the first rotating wheel assembly 34. A second U-shaped bracket is welded at both ends of the support block. Two second pins are respectively clamped in the grooves in the second U-shaped brackets at both ends and can rotate in the grooves. One end of the second pin is fixedly connected to the second ball pin, which is welded from a sphere and two cylinders. The other end of the second pin is connected to the second rotating wrench. When disassembly or installation is required, the second rotating wrench is rotated. At this time, the second ball pin also rotates through the second pin, and changes from a longitudinal state to a transverse state. At this time, the first rotating wheel assembly 34 and the second rotating wheel assembly 35 can be installed and removed from the wire laying head frame 1 by grabbing the second rotating wrench and sliding it outward.

[0074] Several pneumatic push rods are fixed on the support block, and the output end of each pneumatic push rod is hinged downward with a fixed plate, and a second rotating wheel is arranged between two adjacent fixed plates. When the pneumatic push rod is pushed, the second rotating wheel is driven to approach or move away from the bottom to the upper left obliquely. When several tow bodies on the left side need to be transported downward to the pressure roller end of the wire laying head, the pneumatic push rod is extended and retracted, and the fixed plate will also drive the second rotating wheel to bounce to the upper left obliquely, thereby extending the second rotating wheel to approach or move away from the second roller assembly 33. At the same time, each second rotating wheel only controls one tow body, realizing the control of a single tow body in the wire laying process, and the increased pressing force will also ensure the stability of the tow body during the wire laying process.

[0075] like Figure 1 and Figure 5-Figure 6 As shown, in a specific implementation, each of the cutter assemblies 4 includes: A first shell, a connecting assembly and a cutter assembly 4 are connected in sequence, the first shell has an accommodating cavity 41 inside, a feeding channel 43 is formed between the first shell and the connecting assembly, the accommodating cavity 41 is communicated with the feeding channel 43, the connecting assembly has a cutter channel 42 inside, the extension direction of the cutter channel 42 intersects and is communicated with the extension direction of the feeding channel 43, the connecting assembly is connected to the frame 1, and the feeding channel 43 is used for the tow body transported by the corresponding side of the heavy delivery assembly 3 to pass through; An abutment block 44, wherein the abutment block 44 has a first end and a second end opposite to each other, wherein the first end is rotatably connected to the accommodation space; An elastic portion 45, one end of which is connected to the accommodating space, and the other end of which is connected to the second end of the abutting block 44, and the elastic portion 45 is used to provide a rebound force for the abutting block 44; Among them, the cutting tool assembly 4 can sequentially pass through the cutting tool channel 42 and the feeding channel 43, and press the tow body against the abutting block 44 in the accommodating cavity 41. The second end of the abutting block 44 compresses the elastic part 45 to cut the tow body.

[0076] Specifically, the cutting tool assembly 4 includes a cutting knife and a cylinder 46 connected in sequence. The cutting knife is located inside the cutting tool channel 42. The cylinder 46 is connected to the connecting assembly. The cutting end of the cutting knife背离 the cylinder 46 presses the tow body to be cut against the abutting block 44 in the accommodating cavity 41.

[0077] When the cutting knife presses the corresponding tow body against the corresponding abutting block 44, the abutting block 44 is subjected to pressure and compresses the elastic part 45, so that the second end of the abutting block 44 rotates in a direction away from the cutting tool assembly 4, which can effectively avoid hard contact between the cutting knife and the abutting block 44, avoid the problem of tool damage, and at the same time extend the service life of the tool.

[0078] After the cutting knife completes the cutting action, the cutting knife releases the pressing effect on the abutting block 44. Under the action of elastic potential energy, the elastic part 45 pushes the abutting block 44 to reset, so as to facilitate the cutting knife to cooperate with the corresponding abutting block 44 to perform the next cutting process on the corresponding tow body.

[0079] It should be noted that the feeding channel 43 and the cutting tool channel 42 can be perpendicular to each other, or can have a certain included angle. The included angle can be an acute angle or an obtuse angle, as long as the feeding channel 43 and the cutting tool channel 42 intersect. Since the feeding channel 43 and the cutting tool channel 42 intersect and communicate, the cutting knife can pass through the cutting tool channel 42 and press the corresponding tow body to be cut in the feeding channel 43 against the corresponding abutting block 44 to achieve the effect of cutting the tow body.

[0080] The elastic part 45 includes a spring. One end of the spring is connected to the side of the accommodating cavity 41背离 the feeding channel 43, and the other end of the spring is connected to the second end of the abutting block 44.

The connecting assembly also includes at least one partition plate, which is arranged in the cutter channel 42 and divides the cutter channel 42 into two sub-channels arranged in parallel along the second direction, for each of which a cutting knife passes at the same time. The number of sub-channels, the number of cutting knives, the number of feed channels 43, the number of abutment blocks 44 and the number of elastic parts 45 are all used to adapt to the number of tow bodies to be cut, and correspond one to one. The second direction is as shown in FIG. Figure 6 The horizontal direction shown in , wherein if the first direction is the X-axis direction of a plane, then the second direction is the Y-axis direction of the plane, and the first direction and the second direction are perpendicular to each other in the plane. If there are at least two partitions, then the partitions are arranged in the second shell at intervals along the second direction, and the second shell is divided into three sub-channels arranged in parallel along the second direction, for each of which a cutting knife passes through at the same time.
