Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and particularly to a device for conveying flexible filaments. Background Art

[0002] In modern industrial production, flexible filament materials, such as carbon fibers, are widely used in many fields due to their unique properties. However, for the conveyance of flexible fibers, there are currently many severe challenges. Existing fiber threading equipment exposes a series of obvious defects when dealing with flexible fibers, especially carbon fibers.

[0003] Due to the easily bendable characteristics of flexible fibers themselves, they are extremely prone to bending during the threading process. This not only affects the integrity of the fibers but also may lead to a decline in their performance, unable to meet the stringent requirements for fiber quality in high-end products. Moreover, the problem of fiber fuzzing frequently occurs, and the fuzzed fibers are prone to entanglement with each other during subsequent processing, further increasing the processing difficulty.

[0004] More prominently, existing equipment can transport flexible fibers up to only 10 mm at most at a time, and the conveying distance is extremely short. This short-distance conveyance severely restricts production efficiency, hinders the smooth progress of subsequent processes, destroys the continuity of the entire production process, and cannot meet the requirements of large-scale and high-efficiency production. In summary, it is of great practical significance and urgency to develop a device for conveying flexible filaments that can effectively overcome the above problems. Summary of the Invention

[0014] Preferably, the first driving device adopts a linear slide, and the linear slide adopts an electric slide or a manual slide;

[0017] Preferably, the first fixed clamping assembly includes a second fixed seat fixedly connected to the workbench and a fixed jaw mounted on the second fixed seat, and the fixed jaw is used for clamping the flexible filament to be conveyed.

[0018] Preferably, the second fixed clamping assembly includes a fixed base, a third fixed seat, and a pressing cylinder mounted on the third fixed seat. The fixed base and the third fixed seat are respectively fixedly connected to the workbench. The free end of the pressing cylinder faces downward and is fixedly provided with a pressing head. The top surface of the fixed base is located directly below the pressing head and is used to support the flexible filament. The pressing cylinder is used to drive the pressing head to press the flexible filament on the fixed base.

[0019] Preferably, it further includes a second fixed guiding assembly. The second fixed guiding assembly includes a fourth fixed seat fixedly connected to the workbench and a second fixed conduit fixedly connected to the fourth fixed seat. All the sliding conduits, the first fixed conduit, and the second fixed conduit are coaxial. The first fixed clamping assembly is located between the second fixed guiding assembly and the wire feeding jaw.

[0020] Preferably, all the first magnets and the second magnets are permanent magnets;

[0021] Or all the first magnets and the second magnets are electromagnets. When all the first magnets and the second magnets are electromagnets, it further includes a control unit, and the control unit is used to control the on-off of all the first magnets and the second magnets.

[0022] Preferably, the materials of all the sliding conduits and the first fixed conduit are ceramics, and the inner walls of all the sliding conduits and the first fixed conduit are smooth.

[0024] Preferably, among any two of the sliding conduits, the length of the sliding conduit away from the wire feeding jaw is less than the length of the other sliding conduit;

[0025] The inner diameter of the sliding conduit is 3% - 5% larger than the diameter of the flexible filament to be conveyed, and the inner diameter of the first fixed conduit is equal to the inner diameter of the sliding conduit.

[0026] The present invention has achieved the following technical effects compared with the prior art:

[0027] The device for transporting flexible filaments according to the present invention is provided with a plurality of sliding guide assemblies spaced along the first horizontal direction. The sliding conduits in each sliding guide assembly can provide a guiding effect for the flexible filaments, avoiding the bending phenomenon of the flexible filaments during transportation due to their easily bendable characteristics, thus ensuring the integrity of the flexible filaments and meeting the strict requirements for fiber quality in high-end products.

[0028] Furthermore, in the device of the present application, the arrangement of the plurality of sliding guide assemblies and the sliding fit between the sliding conduits and the support seats enable the plurality of sliding conduits to work together sequentially when the wire feeding jaws reciprocate along the first horizontal direction to transport the flexible filaments, effectively increasing the transportation distance of the flexible filaments. The single transportation distance can reach at least 40 mm, meeting the requirements for the transportation distance in large-scale and high-efficiency production and ensuring the continuity of the production process.

[0029] Furthermore, the transportation distance of the device for transporting flexible filaments according to the present invention during transportation can be controlled by controlling the formation of the wire feeding jaws, so it can be steplessly adjusted according to the required transportation distance, which is convenient to use.

[0030] Furthermore, the inner walls of all the sliding conduits and the first fixed conduit are smooth, and rounded chamfers are provided at both ends of the pipe orifices, further reducing the friction between the flexible filaments and the inner walls of the conduits. On the one hand, it reduces the possibility of fiber fuzzing of the flexible filaments, reduces the problem of fiber entanglement caused by fuzzing, and reduces the subsequent processing difficulty; on the other hand, it also reduces the wear of the flexible filaments and reduces the loss and debris generation of the flexible filaments due to friction during transportation.

[0031] Furthermore, the first driving device drives the wire feeding jaws to reciprocate along the first horizontal direction, which can realize the rapid transportation of the flexible filaments. At the same time, the first fixed clamping assembly and the second fixed clamping assembly can respectively clamp the flexible filaments to be transported when the wire feeding jaws need to return to the original position, playing a role in stabilizing the flexible filaments and ensuring the smooth progress of the transportation process, thereby improving the transportation efficiency of the flexible filaments.

[0032] Furthermore, the sliding conduits are slidably matched with the support seats along the first horizontal direction through linear bearings, making the sliding of the sliding conduits smoother and more stable. The arrangement of the first magnet and the second magnet repelling each other can maintain the relative positions of the respective sliding conduits to a certain extent, enabling the respective sliding conduits to quickly reset. When the first magnet and the second magnet are electromagnets, by controlling the control unit to turn them on and off, the positional relationship between the sliding conduits can be flexibly adjusted according to the actual transportation requirements, improving the applicability of the device.

[0033] Furthermore, the materials of all the sliding ducts, the first fixed duct, and the second fixed duct are ceramics. The ceramic material has characteristics such as high hardness and good wear resistance, which can effectively protect the flexible filament from being worn by the flexible filament during transportation, and extend the service life of the sliding duct, the first fixed duct, and the second fixed duct. At the same time, the setting that the inner diameter of the duct is 10%-20% larger than the diameter of the flexible filament can not only ensure the smooth passage of the flexible filament through the duct, but also avoid the bending phenomenon of the flexible filament in the duct during transportation due to the too large inner diameter of the duct.

[0042] The object of the present invention is to provide a device for conveying flexible filaments to solve the problems existing in the above-mentioned prior art and improve the conveying efficiency of flexible filaments.

[0043] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] As Figures 1 to 5 shown, this embodiment provides a device for conveying flexible filaments, including:

[0045] Workbench 19;

[0046] A driving assembly, the driving assembly includes a first driving device 1 fixedly connected to the workbench 19 and a wire feeding jaw 2 connected to the output end of the first driving device 1. The wire feeding jaw 2 is made of non-magnetic material; the driving device is used to drive the wire feeding jaw 2 to reciprocate along the first horizontal direction, and the wire feeding jaw 2 is used to clamp the flexible filament 18 to be conveyed;

[0047] At least two sliding guide assemblies arranged at intervals along the first horizontal direction. Each sliding guide assembly includes a horizontally arranged sliding conduit 4 and a support seat 3 fixedly connected to the workbench 19. The sliding conduit 4 is slidably matched with the support seat 3 in the same sliding guide assembly along the first horizontal direction, and the axial direction of the sliding conduit 4 is the same as the first horizontal direction; first magnets 5 are fixedly provided at both ends of each sliding conduit 4, and any two adjacent first magnets 5 located on different sliding conduits 4 can repel each other;

[0048] A first fixed guide assembly, all the sliding guide assemblies are located between the wire feeding jaw 2 and the first fixed guide assembly; the first fixed guide assembly includes a first fixed seat 7 fixedly connected to the workbench 19 and a first fixed conduit 9 fixedly arranged on the first fixed seat 7. All the sliding conduits 4 and the first fixed conduit 9 are coaxial and allow the flexible filament 18 to pass through; a second magnet 8 is provided at one end of the first fixed conduit 9 close to the sliding guide assembly, and the second magnet 8 can repel the first magnet 5 closest to the second magnet 8;

[0049] A first fixed clamping assembly, the first fixed clamping assembly is used to clamp the flexible filament 18 to be conveyed; the wire feeding jaw 2 is located between the first fixed clamping assembly and the sliding conduit 4 closest to the wire feeding jaw 2;

[0050] The second fixed clamping assembly is used to clamp the flexible filament 18 to be conveyed; the first fixed guiding assembly is located between the second fixed clamping assembly and the sliding conduit 4 closest to the first fixed guiding assembly.

[0051] In this embodiment, by providing a plurality of sliding guiding assemblies arranged at intervals along the first horizontal direction, the sliding conduit 4 in each sliding guiding assembly can provide a guiding effect for the flexible filament 18, avoiding the bending phenomenon of the flexible filament 18 during the conveying process due to its easily bendable characteristic, thereby ensuring the integrity of the flexible filament 18; the setting of a plurality of sliding guiding assemblies and the sliding fit between the sliding conduit 4 and the support base 3 enable the plurality of sliding conduits 4 to work together in sequence when the wire feeding jaw 2 reciprocates along the first horizontal direction to convey the flexible filament 18, effectively increasing the conveying distance of the flexible filament 18, meeting the requirements for the conveying distance in large-scale and high-efficiency production, and ensuring the continuity of the production process.

[0052] In an alternative embodiment of the present embodiment, preferably, the first driving device 1 adopts a linear slide, and the linear slide adopts an electric slide or a manual slide.

[0053] In an alternative embodiment of the present embodiment, preferably, the sliding conduit 4 is slidably engaged with the support base 3 in the same sliding guiding assembly along the first horizontal direction through a linear bearing 6, making the sliding of the sliding conduit 4 smoother and more stable.

[0054] In an alternative embodiment of the present embodiment, preferably, the first fixed clamping assembly includes a second fixed base 14 fixedly connected to the workbench 19 and a fixed jaw 15 mounted on the second fixed base 14, and the fixed jaw 15 is used to clamp the flexible filament 18 to be conveyed.

[0055] In an alternative embodiment of the present embodiment, preferably, the second fixed clamping assembly includes a fixed bearing platform 10, a third fixed base 11, and a pressing cylinder 12 mounted on the third fixed base 11. The fixed bearing platform 10 and the third fixed base 11 are respectively fixedly connected to the workbench 19. The free end of the pressing cylinder 12 faces downward and is fixedly provided with a pressing head 13. The top surface of the fixed bearing platform 10 is located directly below the pressing head 13 and is used to support the flexible filament 18, and the pressing cylinder 12 is used to drive the pressing head 13 to press the flexible filament 18 on the fixed bearing platform 10. When clamping the flexible filament 18 by the second fixed clamping assembly, it only needs to drive the pressing head 13 to move downward through the pressing cylinder 12 to press the flexible filament 18 on the fixed bearing platform 10.

[0056] In an alternative embodiment of the present embodiment, preferably, a second fixed guiding assembly is further included. The second fixed guiding assembly includes a fourth fixed seat 16 fixedly connected to the workbench 19 and a second fixed conduit 17 fixedly connected to the fourth fixed seat 16. All the sliding conduits 4, the first fixed conduit 9, and the second fixed conduit 17 are coaxial. The first fixed clamping assembly is located between the second fixed guiding assembly and the wire feeding jaw 2.

[0057] In an alternative embodiment of the present embodiment, preferably, all the first magnets 5 and the second magnets 8 are permanent magnets. Compared with some electromagnetic devices that require external energy supply, permanent magnets have a lower cost. They do not require additional power supply and complex circuit control systems, reducing the manufacturing and usage costs of the device. At the same time, permanent magnets have a longer service life and do not need to be frequently replaced under normal use conditions, further reducing the long-term usage costs. The device using permanent magnets is relatively simple to maintain. It does not require regular inspection and maintenance of the power supply and control system like electromagnets, reducing the maintenance workload and costs. Only the magnetic property of the magnet and its installation firmness need to be regularly checked, improving the maintainability of the device.

[0058] In an alternative embodiment of the present embodiment, all the first magnets 5 and the second magnets 8 are electromagnets. When all the first magnets 5 and the second magnets 8 are electromagnets, a control unit is further included, which is used to control the power on and off of all the first magnets 5 and the second magnets 8. Although the cost of using electromagnets for the first magnets 5 and the second magnets 8 is relatively higher than that of permanent magnets, the advantage is that during the process of driving the flexible filament 18 to move by the wire feeding jaw 2, the power supply to each electromagnet can be selectively cut off to avoid the problem that the first driving device 1 needs to overcome the magnetic repulsion between the magnets during operation, reducing energy consumption. And when it is necessary to reset all the sliding conduits 4, the first magnets 5 and the second magnets 8 can be powered on again.

[0059] In an alternative embodiment of the present embodiment, a third magnet (not shown in the figure) is provided on the side of the wire feeding jaw 2 close to the sliding guiding assembly. The third magnet can repel the first magnet 5 closest to the wire feeding jaw 2. The purpose of setting the third magnet is to further control the relative position between the sliding conduit 4 closest to the wire feeding jaw 2 and the wire feeding jaw 2. It should be noted that the third magnet can also be a permanent magnet or an electromagnet. Preferably, when all the first magnets 5 and the second magnets 8 are electromagnets, the third magnet is also an electromagnet, and the control unit can also control the power on and off of the third magnet. When all the first magnets 5 and the second magnets 8 are permanent magnets, the third magnet can be a permanent magnet.

[0060] In an alternative embodiment of the present embodiment, preferably, the materials of all the sliding ducts 4, the first fixed duct 9, and the second fixed duct 17 are ceramics, and the inner walls of all the sliding ducts 4, the first fixed duct 9, and the second fixed duct 17 are smooth; rounded chamfers are respectively provided at both ends of all the sliding ducts 4, both ends of the first fixed duct 9, and both ends of the second fixed duct 17. With such a setting, the friction between the flexible filament 18 and the inner walls of each duct (including the sliding duct 4, the first fixed duct 9, and the second fixed duct 17) is further reduced. On the one hand, the possibility of fiber fuzzing of the flexible filament 18 is reduced, the problem of fiber entanglement caused by fuzzing is reduced, and the subsequent processing difficulty is lowered; on the other hand, the wear of the flexible filament 18 is also reduced, and the loss and debris generated by the friction of the flexible filament 18 during the conveying process are reduced.

[0061] In an alternative embodiment of the present embodiment, preferably, among any two sliding ducts 4, the length of the sliding duct 4 farther from the wire feeding jaw 2 is less than the length of the other sliding duct 4; the reason for such a setting is that during the conveying process, the sliding duct 4 closer to the wire feeding jaw 2 needs to move a longer distance. Therefore, the sliding duct 4 that needs to move a longer distance has a longer length, and the sliding duct 4 that needs to move a shorter distance has a shorter length, which can make the device more compact and reasonable, reduce space occupation, and at the same time facilitate the connection and cooperation between various components, improving the stability and reliability of the device.

[0062] The inner diameter of the sliding duct 4 is 3% - 5% larger than the diameter of the flexible filament 18 to be conveyed, and the inner diameters of the first fixed duct 9 and the second fixed duct 17 are equal to the inner diameter of the sliding duct 4; setting the inner diameters of each duct in this way can ensure that the flexible filament 18 smoothly passes through each duct, and can also prevent the flexible filament 18 from bending in the duct during the conveying process due to the too large inner diameter of each duct.

[0063] The specific use process of the device for conveying the flexible filament in this embodiment is as follows:

[0064] Step S1, as Figure 4 shown, manually pass the flexible filament 18 to be conveyed through the second fixed duct 17 (if provided), each sliding duct 4, and the first fixed duct 9 in sequence;

[0065] Step S2, control the wire feeding jaw 2 to clamp the above-mentioned flexible filament 18;

[0066] Step S3: Drive the wire feeding jaw 2 to move towards the first fixed catheter 9 through the first driving device 1 for wire feeding operation. During the process of the wire feeding jaw 2 moving towards the first fixed catheter 9, the intervals between the wire feeding jaw 2 and the sliding catheter 4 closest to the wire feeding jaw 2, between each sliding catheter 4, and between the first fixed catheter 9 and the sliding catheter 4 closest to the first fixed catheter 9 all gradually decrease; refer to Figure 5 , after reaching the set conveying distance, or after all the above intervals are reduced to 0, turn off the first driving device 1 to stop driving the wire feeding jaw 2 from moving;

[0067] Step S4: Control the first fixed clamping assembly and the second fixed clamping assembly to clamp the flexible filament 18 simultaneously;

[0068] Step S5: Perform subsequent process operations on the already conveyed flexible filament 18, such as cutting it with a cutter;

[0069] Step S6: Release the clamping of the flexible filament 18 by the wire feeding jaw 2, and drive the wire feeding jaw 2 to return to the initial position through the first driving device 1;

[0070] During the process of the wire feeding jaw 2 returning to the initial position: If both the first magnet 5 and the second magnet 8 are permanent magnets, each sliding catheter 4 will move under the action of magnetic repulsion force, so that each slide catheter will also return to the initial position; If both the first magnet 5 and the second magnet 8 are electromagnets, then during the process from Step S1 to Step S5, the first magnet 5 and the second magnet 8 should be kept powered off, and then the first magnet 5 and the second magnet 8 are powered on during Step S6, so that each sliding catheter 4 will move under the action of magnetic repulsion force to return to the initial position;

[0071] It should be noted that at the initial position, the intervals between the wire feeding jaw 2 and the sliding catheter 4 closest to the wire feeding jaw 2, between each sliding catheter 4, and between the first fixed catheter 9 and the sliding catheter 4 closest to the first fixed catheter 9 can all ensure that the flexible filament 18 will not bend or be bent during the conveying process, and can ensure that each sliding catheter 4 can return to this position under the action of magnetic repulsion force; Therefore, in practical applications, for the specific setting of the initial position, it needs to be determined by technicians through experiments in advance;

[0072] Step S7: Control the wire feeding jaw 2 to clamp the flexible filament 18, and release the clamping of the flexible filament 18 by the first fixed clamping assembly and the second fixed clamping assembly;

[0073] Then, repeat Step S3 to Step S7 to perform cyclic conveying of the flexible filament 18 until the conveying work of the flexible filament 18 is completed.

[0074] In addition, the reason why the wire feeding jaw 2 is made of non-magnetic material is to prevent the first magnet 5 closest to the wire feeding jaw 2 from attracting to the wire feeding jaw 2 during the process of the wire feeding jaw 2 and the sliding conduit 4 returning to the initial position, which may affect the return of the sliding conduit 4 closest to the wire feeding jaw 2 to the initial position, so as to improve the working stability of the device.

[0075] Specific examples are used in the present invention to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
