Method for treating fiber winding roller

Abstract

The invention provides a fiber roller winding treatment method, which comprises the following steps of: S1, breaking yarns on the upstream side of a driving roller which is wound, and leading out the broken yarns; and S2, a roller winding tow is cut at the position of the transmission roller where roller winding occurs through a triangular cutting method. Wherein during roller winding treatment, firstly, the step S1 is adopted for conducting yarn breaking on the upstream side of the transmission roller where roller winding happens, the broken yarn is led out, in this way, it can be avoided that tows are continuously wound around the transmission roller, and therefore the influence of the roller winding tows on adjacent spinning positions can be reduced. In addition, since the roller-wound tows become loose and fluffy from tight in the cutting process, the adhesion breadth of the roller-wound tows on the roller surface is widened, while the tows are cut by adopting the triangular cutting method in the step S2, the situation that the fluffy roller-wound tows deviate too much towards one direction or two sides can be avoided, and the cutting quality of the tows is improved. Therefore, the influence of the roller winding tows on the adjacent spinning positions can be further reduced, and yield reduction caused by yarn breakage of the adjacent spinning positions due to roller winding treatment is avoided.

Description

Technical Field

[0001] The invention belongs to the technical field of carbon fiber processing, and in particular relates to a fiber winding roller disposal method. Background Art

[0002] Polyacrylonitrile-based carbon fiber materials have both high performance and low density. They are typical dual-use key materials and typical representatives of leading material revolution. In recent years, with the growth of domestic market demand, the demand for low-cost and stable production of carbon fiber has become more urgent.

[0003] If roller entanglement occurs during the industrial production of carbon fiber, it will greatly affect the stable production of carbon fiber. Roller entanglement treatment poses great safety risks. Improper treatment can easily cause large-scale wire breakage at multiple spinning positions, and even cause shutdown and safety accidents. If roller entanglement occurs, existing production companies generally do not stop the machine, and the transmission rollers are still running during the roller entanglement treatment process. Among them, when dealing with roller entanglement, the roller spinning position will become more and more entangled because the source is not cut off. And in the process of using a hook knife to cut off the roller-entangled tow, the roller-entangled tow becomes loose from tight, which is easy to cover or hook adjacent tows, affecting adjacent spinning positions, so this problem needs to be solved. Summary of the invention

[0004] Therefore, the present invention provides a fiber winding roller disposal method, which can solve the technical problem in the prior art that when the winding roller part is cut off, the winding roller bundle becomes loose from tight, easily covers or hooks the adjacent bundles, and affects the adjacent spinning positions.

[0005] In order to solve the above problems, the present invention provides a fiber winding roller disposal method, which comprises the following steps:

[0006] Step S1: Cutting the wire on the upstream side of the transmission roller where the roller winding occurs, and leading out the broken wire;

[0007] Step S2: using a triangle cutting method to cut the roller-wrapped wire bundle at the driving roller where the roller entanglement occurs;

[0008] The winding roller tow has a first side and a second side opposite to each other along the axial direction of the driving roller; the triangle cutting method is specifically as follows:

[0009] First, cutting is performed according to step S21, and step S21 is: first, the first side of the roller-wound wire bundle is cut from the top to the obliquely downward direction away from the second side, and then the second side of the roller-wound wire bundle is cut from the top to the obliquely downward direction away from the first side, and then the bottom of the roller-wound wire bundle is cut from the second side to the first side; if there is still a roller-wound wire bundle on the transmission roller of the roller after step S21, cutting is performed according to step S22, otherwise the cutting is terminated;

[0010] Among them, step S22 is: first cut the second side of the roller-wrapped wire bundle from the top to the obliquely downward direction away from the first side, then cut the first side of the roller-wrapped wire bundle from the top to the obliquely downward direction away from the second side, and then cut the bottom of the roller-wrapped wire bundle from the first side to the second side; if there is still a roller-wrapped wire bundle on the transmission roller of the roller after step S22, continue cutting according to the above-mentioned step S21, otherwise end the cutting.

[0011] In some embodiments, when cutting the roller-wrapped tow, an upper baffle and a lower baffle are provided at the driving roller where the roller wrapping occurs to assist in cutting the roller-wrapped tow;

[0012] Wherein, the upper baffle plate is arranged opposite to the lower baffle plate, and the upper baffle plate is located on the upper side of the roller-wound wire bundle, and the lower baffle plate is located on the lower side of the roller-wound wire bundle.

[0013] In some embodiments, the minimum distance between the upper baffle plate and the lower baffle plate and the roller surface of the driving roller is d1, d1 = 20-50 mm;

[0014] And / or, the distance between the upper baffle and the lower baffle is d2, d2 = 50-100 mm.

[0015] In some embodiments, in step S1, the wire is cut at the upstream side of the transmission roller where the roller winding occurs, specifically: the wire is cut at the upstream active transmission roller adjacent to the transmission roller where the roller winding occurs.

[0016] In some embodiments, the number and position of the broken wires in step S1 satisfy:

[0017] When the width of the winding roller tow d3 < ba, only the tow at the winding roller spinning position needs to be cut;

[0018] When the width d3 of the wound roller yarn bundle ≥ ba, the number of broken yarns in the yarn bundle = the width of the wound roller yarn bundle ÷ (ba) + 2, wherein a refers to the width of each yarn bundle on the transmission roller where the wound roller occurs, and b refers to the center distance between two adjacent spinning position yarn bundles. The broken yarn spinning positions are the wound roller spinning position and the spinning positions on both sides of the wound roller spinning position.

[0019] In some embodiments, the fiber winding roller treatment method further comprises:

[0020] A positioning ring is provided, and in step S1 the broken wire is led out of the positioning ring.

[0021] In some embodiments, the upper end of the positioning ring has an opening, so that the positioning ring is in an arc shape; wherein the arc angle of the arc is 270°-320°;

[0022] and / or, the positioning ring is higher than the driving roller by more than 100 mm;

[0023] And / or, the positioning ring is arranged on at least one side of the driving roller in the downstream direction.

[0024] In some embodiments, when cutting the roller-wrapped tow, a separator is used to separate the unaffected tows on both sides of the roller-wrapped tow; and the separation distance is less than twice the center distance between adjacent spinning position tows.

[0025] The fiber winding roller treatment method provided by the present invention has the following beneficial effects:

[0026] 1. When dealing with roller entanglement, firstly, the step S1 is adopted to cut the wire on the upstream side of the driving roller where the roller entanglement occurs, and the broken wire is led out, so that the wire bundle is prevented from being continuously wound around the driving roller, thereby reducing the influence of the roller entanglement wire bundle on the adjacent spinning position. In addition, since the roller entanglement wire bundle becomes loose and fluffy from tight during the cutting process, the width of the roller entanglement wire bundle attached to the roller surface becomes wider, and the present invention adopts the triangular cutting method in step S2 to cut the wire bundle, which can avoid the roller entanglement wire bundle from deviating too much in one direction or on both sides after being fluffed, thereby further reducing the influence of the roller entanglement wire bundle on the adjacent spinning position, avoiding the reduction of production caused by the broken wire at the adjacent spinning position caused by the treatment of roller entanglement, and improving the efficiency and stability of the treatment of roller entanglement.

[0027] 2. After the wire bundle wrapped around the roller is cut off, the cut wire bundle wrapped around the roller can be pulled out from between the upper baffle and the lower baffle. On the one hand, during the process of the operator cutting off the wire bundle wrapped around the roller, the upper baffle and the lower baffle can isolate the operator from the high-speed rotating transmission roller, thereby improving safety and avoiding safety problems. On the other hand, the upper baffle and the lower baffle can provide a fulcrum for pulling the wire bundle from the high-speed rotating transmission roller, making it convenient for the operator to successfully pull the wire bundle out from between the upper baffle and the lower baffle.

[0028] 3. The wire breaking method of the present invention can achieve wire breaking in the smallest range, which not only reserves sufficient width for handling broken wires, but also minimizes the number of wire bundles affected by the winding roller, thereby reducing production waste and handling difficulty.

[0029] 4. The positioning ring has a guiding function. By setting the positioning ring, it is beneficial to the traction of broken wire.

[0030] 5. When cutting the roller-wound tow, use a separator to separate the unaffected tows on both sides of the roller-wound tow, and the separation distance should be less than twice the center distance of the adjacent spinning position tows, so as to avoid the influence of broken wires on the tows at the adjacent spinning positions.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0045] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0046] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0047] See also Figure 1-8 As shown, according to an embodiment of the present invention, a fiber winding roll disposal method is provided, which includes the following steps:

[0048] Step S1: Cut the wire on the upstream side of the driving roller 1 where the roller winding occurs, and lead out the broken wire.

[0049] Step S2: Using a triangle cutting method to cut the roller-wrapped wire bundle 3 at the driving roller 1 where the roller wrapping occurs. The roller-wrapped wire bundle 3 has a first side 3-1 and a second side 3-2 opposite to each other along the axial direction of the driving roller 1. The triangle cutting method is specifically as follows:

[0050] like Figure 2 and Figure 3 As shown, firstly, cutting is performed according to step S21, and step S21 is: firstly, the first side 3-1 of the roller-wound wire bundle is cut from the top to the obliquely downward side away from the second side 3-2; then, the second side 3-2 of the roller-wound wire bundle is cut from the top to the obliquely downward side away from the first side 3-1; and then, the bottom of the roller-wound wire bundle 3 is cut from the second side 3-2 to the first side 3-1. If there is still a roller-wound wire bundle 3 on the transmission roller 1 that is wound after step S21, cutting is performed according to step S22, otherwise, the cutting is terminated.

[0051] Wherein, step S22 is: firstly, the second side 3-2 of the roller-wound wire bundle is cut from the top to the obliquely downward part away from the first side 3-1; then, the first side 3-1 of the roller-wound wire bundle is cut from the top to the obliquely downward part away from the second side 3-2; and then, the bottom of the roller-wound wire bundle 3 is cut from the first side 3-1 to the second side 3-2. If there is still a roller-wound wire bundle 3 on the transmission roller 1 where the roller is wound after step S22, then the cutting is continued according to the above step S21, otherwise, the cutting is terminated.

[0052] In the above example, when dealing with roller winding, firstly, step S1 is adopted to cut the wire on the upstream side of the driving roller 1 where roller winding occurs, and the broken wire is led out, so that the wire bundle is prevented from being continuously wound around the driving roller 1, thereby reducing the influence of the roller winding wire bundle 3 on the adjacent spinning position 2. In addition, since the roller winding wire bundle 3 becomes loose and fluffy from tight during the cutting process, the width of the roller winding wire bundle 3 attached to the roller surface becomes wider, and the present invention uses the triangular cutting method in step S2 to cut the wire bundle, which can avoid the roller winding wire bundle 3 from deviating too much in one direction or on both sides after being fluffed, thereby further reducing the influence of the roller winding wire bundle 3 on the adjacent spinning position 2, avoiding the reduction of production caused by the broken wire in the adjacent spinning position 2 caused by the treatment of roller winding, and improving the efficiency and stability of the treatment of roller winding.

[0053] In some embodiments, Figure 2 and Figure 3As shown, the cutting direction of the first side 3-1 of the above-mentioned roller-wrap wire bundle from the top to the obliquely downward direction away from the second side 3-2 is the first direction, and the first direction is 25°-35° with the plane where the roller-wrap wire bundle 3 on the downstream side of the drive roller 1 is located. Preferably, the first direction is 30° with the plane where the roller-wrap wire bundle 3 on the downstream side of the drive roller 1 is located. Similarly, the cutting direction of the second side 3-2 of the above-mentioned roller-wrap wire bundle from the top to the obliquely downward direction away from the first side 3-1 is the second direction, and the second direction is 25°-35° with the plane where the roller-wrap wire bundle 3 on the downstream side of the drive roller 1 is located. Preferably, the second direction is 30° with the plane where the roller-wrap wire bundle 3 on the downstream side of the drive roller 1 is located.

[0054] Figure 2 A schematic diagram of a triangle cutting method is shown in FIG. 1 , wherein the cutting sequence in step S21 is 1-1, 1-2 and 1-3. The cutting sequence in step S22 is 2-1, 2-2 and 2-3.

[0055] In some embodiments, Figure 4 and Figure 5 As shown, when cutting the roller-wrapped tow 3, an upper baffle 5 and a lower baffle 6 are arranged at the driving roller 1 where the roller entanglement occurs to assist in cutting the roller-wrapped tow 3. The upper baffle 5 is arranged opposite to the lower baffle 6, and the upper baffle 5 is located on the upper side of the roller-wrapped tow 3, and the lower baffle 6 is located on the lower side of the roller-wrapped tow 3.

[0056] In the above example, after the roller-wrapped wire bundle 3 is cut off, the cut roller-wrapped wire bundle 3 can be pulled out from between the upper baffle plate 5 and the lower baffle plate 6. On the one hand, during the process of the operator cutting off the roller-wrapped wire bundle, the upper baffle plate 5 and the lower baffle plate 6 can isolate the operator from the high-speed rotating transmission roller 1, thereby improving safety and avoiding safety problems. On the other hand, the upper baffle plate 5 and the lower baffle plate 6 can provide a fulcrum for pulling the wire bundle out of the high-speed rotating transmission roller 1, making it convenient for the operator to successfully pull the wire bundle out from between the upper baffle plate 5 and the lower baffle plate 6.

[0057] In some embodiments, Figure 4 and Figure 5 As shown, the aforementioned upper baffle 5 and lower baffle 6 can be controlled by a driving mechanism. Among them, one end of both the upper baffle 5 and the lower baffle 6 is a rotating end, and the other end of both is a free end. The driving mechanism is used to drive the upper baffle 5 and the lower baffle 6 to rotate, so that the upper baffle 5 and the lower baffle 6 are both ejected or retracted. When the upper baffle 5 and the lower baffle 6 are both ejected, the free ends of the upper baffle 5 and the lower baffle 6 are opposite, and the two are relatively closed. When the upper baffle 5 and the lower baffle 6 are both retracted, the free ends of the upper baffle 5 and the lower baffle 6 are relatively open. Among them, the driving mechanism may include a motor 4 and a screw 7, and the driving mechanism drives the upper baffle 5 and the lower baffle 6 to be ejected or retracted through the motor 4 and the screw 7.

[0058] In some embodiments, Figure 5 As shown, the minimum distance between the upper baffle plate 5 and the lower baffle plate 6 and the roller surface of the driving roller 1 is d1, d1 = 20-50 mm. If d1 is too small, the upper baffle plate 5 and the lower baffle plate 6 are prone to get caught after the roller-wrapped wire bundle 3 becomes fluffy during the cutting process, which affects the cutting process; if d1 is too large, the hook knife cannot reach the roller-wrapped wire bundle 3 during the cutting process, which affects the cutting process.

[0059] In some embodiments, Figure 5 As shown, the distance between the upper baffle plate 5 and the lower baffle plate 6 is d2, d2 = 50-100 mm. If d2 is too large, it will not play a protective role, and fingers or cutting tools such as hooks will easily get involved in the transmission roller 1; if d2 is too small, the operation of cutting the roller-wrapped wire bundle 3 is limited, affecting the cutting, or even making it impossible to perform the cutting operation.

[0060] In some embodiments, the wire is cut at the upstream side of the drive roller 1 where the roller is wound in the aforementioned step S1, specifically: the wire is cut at the upstream active drive roller 12 adjacent to the drive roller 1 where the roller is wound. Such a design is mainly because if the wire is cut at the driven drive roller 1, it is easy to be wound, and the wire drawing after the wire is broken is laborious.

[0061] In some embodiments, Figure 3 As shown, the number and position of the broken wires in the aforementioned step S1 satisfy: when the width d3 of the winding roller tow 3 is less than ba, only the tow at the winding roller spinning position is broken. When the width d3 of the winding roller tow 3 is greater than or equal to ba, the number of broken wires of the tow = the width of the winding roller tow 3 ÷ (ba) + 2, wherein a refers to the width of each tow on the driving roller 1 where the winding roller occurs, b refers to the center distance between the two adjacent spinning positions of the tow, and the broken spinning position is the winding roller spinning position and the two adjacent spinning positions of the winding roller spinning position.

[0062] In the above example, by adopting the above method to break the wire, the minimum range of wire breaking can be achieved, which not only reserves sufficient width for handling the broken wire, but also minimizes the number of wire bundles affected by the disposal roller, thereby reducing production waste and disposal difficulty.

[0063] In some embodiments, Figure 6 and Figure 7 As shown, the aforementioned fiber winding roller treatment method further includes: setting a positioning ring 11, and in step S1, leading the broken wires out of the positioning ring 11.

[0064] The positioning ring 11 has a guiding function. The positioning ring 11 is provided to facilitate the pulling of the broken wire.

[0065] In some embodiments, Figure 7As shown, if the number of broken wire bundles exceeds one, three broken wire bundles are combined into one and drawn out from the positioning ring 11 for wire drawing. Figure 7 A schematic diagram showing three bundles of broken wires being led out from the same positioning ring 11 is shown. Figure 7 The three broken silk bundles are 5-1, 5-2 and 5-3.

[0066] In some embodiments, Figure 6 As shown, a positioning ring 11 can be provided at the downstream position of both axial sides of each active transmission roller 12. In the actual production process, each spinning position 2 has a single bundle of yarns. The production scale of each enterprise is different, and the number of spinning positions 2 is also different. Dry-jet wet spinning generally has 20-30 spinning positions 2. Figure 3 As shown, if 5 bundles of wire need to be cut due to winding, the wires can be cut behind the active drive roller 12 before the winding drive roller 1. If the 5 bundles of wire to be cut are 5 bundles of wire arranged in sequence, the 5 bundles of wire can be drawn out from the same positioning ring 11 for wire drawing. Figure 6 As shown, if the 5 bundles of broken wire are separated into 3 bundles of wire on the left and 2 bundles of wire on the right by normal bundles of wire, the 3 bundles of wire on the left are drawn out from the same positioning ring 11 on the left for drawing, and the 2 bundles of wire on the right are drawn out from the same positioning ring 11 on the right for drawing.

[0067] In some embodiments, Figure 7 As shown, the upper end of the positioning ring 11 has an opening 101, so that the positioning ring 11 is in an arc shape. The arc angle of the arc is 270°-320°. Preferably, the arc angle of the arc is 295°.

[0068] In the above example, the opening 101 at the upper end of the positioning ring 11 facilitates the yarn bundle to enter and exit the positioning ring 11. By setting the arc angle to 270°-320°, it is possible to prevent the yarn bundle from breaking off the positioning ring 11 during the wire drawing process, and then escaping from the transmission roller surface, and being wound back to the previous process, causing a large amount of yarn bundles to accumulate and cause production suspension.

[0069] In some embodiments, the aforementioned positioning ring 11 is higher than the driving roller by more than 100 mm to prevent broken wires from affecting the wire bundle on the driving roller 1 .

[0070] In some embodiments, Figure 6 As shown, the aforementioned positioning ring 11 is arranged on at least one side of the downstream direction of the active transmission roller 12. Preferably, positioning rings 11 are arranged on both sides of the downstream direction of the transmission roller 1, so as to facilitate pulling the broken wire out of the corresponding positioning ring 11 according to actual conditions.

[0071] In some embodiments, Figure 7As shown, the aforementioned active transmission roller 12 is driven to rotate by the gear box 9. The aforementioned positioning ring 11 is installed on the railing 10. The railing 10 is located on both sides of the operating platform.

[0072] In some embodiments, Figure 8 As shown, when cutting the roller-wrapped yarn bundle 3, a separator 8 is used to separate the unaffected yarn bundles on both sides of the roller-wrapped yarn bundle 3; and the separation distance is less than twice the center distance of the yarn bundles at the adjacent spinning positions 2 to avoid the broken yarns affecting the yarn bundles at the adjacent spinning positions 2.

[0073] The separator 8 may be a wire fork or a wire guide rack. Figure 8 A schematic diagram of a spinning station 2 before the filament bundle is separated is shown. Fig. 9 A schematic diagram is shown after a separator 8 is used to separate the filament bundles in the spinning position 2. Figure 8 and Fig. 9 1', 2', 3', 4', 5', 6' in the figure represent the yarn bundles of different spinning positions 2. 8 is a separator such as a wire guide frame or a wire fork. b1 is the push-off direction of the spinning position 3', and b2 is the push-off direction of the spinning position 4'. Figure 8 In the , the 3' and 4' positions are not separated. Fig. 9 In the figure, spinning positions 3' and 4' have been separated. a1 refers to the center distance between the fibers of the adjacent spinning positions before the separation of spinning positions 3 and 4. c1 refers to the center distance between the fibers of the adjacent spinning positions after the separation of spinning positions 3' and 4; c1-a1 is the separation distance.

[0074] For ease of understanding, the technical solution of the present invention is specifically described below with reference to three different positions of the transmission roller 1 where roller entanglement occurs.

[0075] Embodiment 1

[0076] When the carbon fiber raw yarn is entangled in the washing process, scissors can be used to cut the entangled yarn bundle 3 behind the upper active transmission roller 12, because the force required for wire drawing after the active transmission roller 12 is relatively small. Then check whether the operation of the remaining spinning positions 2 is affected. After the check is completed, the upper baffle 5 and the lower baffle 6 on the downstream side of the transmission roller 1 where the entanglement occurs are ejected. The operator uses a hook knife to cut the wire at the transmission roller 1 where the entanglement occurs. One person uses tweezers to remove the cut wool balls to avoid entering the transmission part. At the same time, monitor the normal operation of the yarn bundle on the transmission roller 1 to avoid safety problems. After the processing is completed, continue to bring the yarn bundle through the fixed wire guide rod, wrap it around the transmission roller, and put the yarn bundle on the rack.

[0077] By applying the method and the auxiliary device of the present invention to carry out water-washing and roller-winding treatment, the fiber bundle runs completely and stably without causing bifurcation and hairy yarn phenomena, which greatly reduces the probability of stopping production due to roller winding.

[0078] Embodiment 2

[0079] When the carbon fiber precursor is entangled in the hot drawing process, scissors can be used to cut the entangled wire bundle 3 after the active drive roller 12 after washing in the previous stage, because the force required for wire drawing after the active drive roller 12 is small. Then check whether the operation of the remaining spinning positions 2 is affected. After the inspection is completed, the upper baffle 5 and the lower baffle 6 on the downstream side of the drive roller 1 where the entanglement occurs are ejected, and the operator uses a hook knife to cut the wire at the drive roller 1 where the entanglement occurs. One person uses tweezers to remove the cut hair balls to avoid entering the transmission part, and at the same time monitor the normal operation of the wire bundle on the roller to avoid safety problems. After the processing is completed, continue to bring the wire bundle through the hot drawing roller, through the steam drawing furnace, and put the wire bundle on the rack.

[0080] By applying the method and auxiliary device of the present invention to carry out hot winding roller treatment, the fiber tow runs completely and stably without causing large-area winding of the roller, which greatly reduces the probability of stopping production due to winding of the roller. The running tow is located in the center of the wire path, and it can be clearly seen that the tow runs uniformly and stably, and there is no hanging of the adjacent spinning positions 2, and there is no interference with each other.

[0081] Embodiment 3

[0082] When the carbon fiber precursor is entangled in the drying process, scissors can be used to cut the entangled wire bundle 3 behind the oiled active transmission roller 12, and check whether the operation of other spinning positions 2 is affected. After the inspection is completed, the wire drawing personnel will draw the wire, and the upper baffle 5 and the lower baffle 6 on the downstream side of the transmission roller 1 where the entanglement occurs will be ejected. The operator uses a hook knife to cut the wire at the transmission roller 1 where the entanglement occurs, and one person uses tweezers to remove the cut hair balls to avoid entering the transmission part. At the same time, the normal operation of the wire bundle on the monitoring roller is avoided to avoid safety problems. After the processing is completed, continue to lead the wire bundle around the drying roller, pass through the steam pulling furnace, and put the wire bundle on the rack.

[0083] By applying the method and auxiliary device of the present invention to carry out dry roller winding treatment, the fiber bundle runs completely and smoothly without causing large-area roller winding, which greatly reduces the probability of production suspension due to roller winding. The running bundle is located in the center of the wire path, and it can be clearly seen that the bundle runs uniformly and stably, there is no wire hanging phenomenon in adjacent spinning positions 2, and there is no interference with each other.

[0084] The fiber winding roller treatment method of the present invention can handle the winding roller without stopping the machine, and ensure that the existing spinning position 2 fiber bundles maintain stable operation as much as possible, avoiding the situation of large-area winding roller breakage caused by improper handling of the winding roller, and avoiding production accidents and safety accidents caused by it. The method is highly safe and easy to operate. It reduces unnecessary broken wires during the treatment process and ensures the stability of production.

[0085] It is easy for those skilled in the art to understand that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention. These improvements and variations should also be regarded as the protection scope of the present invention.
