Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of carbon fiber production, and particularly relates to a towpiece merging device and method based on a dry-jet wet spinning process. BACKGROUND

[0002] The dry-jet wet spinning process is a preparation method of carbon fiber yarn, which has the advantages of high production efficiency, low cost and stable product quality, and is widely used in the fields of aerospace, automobile industry and sports equipment. Compared with the wet spinning process, the raw silk liquid in the dry-jet wet spinning process is first passed through an air layer after being sprayed through a spinneret, and then enters a coagulation liquid, so as to ensure that the shrinkage rates of the surface layer and the core of the yarn are consistent, and the product quality of the carbon fiber yarn is improved.

[0003] Among them, the conventional spinneret adopts an integral structure, and a thousand to three thousand orifices are arranged on the plate body; since the number of orifices on the integral spinneret is relatively large, the diameter-depth ratio of each orifice needs to be designed to be very small to ensure the ability of the spinneret to resist high-pressure deformation, which causes the technical defect of increasing the manufacturing cost of the spinneret.

[0004] In order to reduce the manufacturing cost of the spinneret, an improvement scheme for the original dry-jet wet spinning process is proposed in the prior art, which specifically adds a process of merging two towpieces in the traditional process steps to realize the production of large-specification towpieces.

[0005] The existing towpiece merging process is performed in the latter stage of one of the coagulation bath process, the washing process and the steam process; and the inventor finds that when merging in the latter stage of the coagulation bath process or the washing process, the washing effect is poor and the residual solvent of the towpiece is high due to the large width of the towpiece and uneven spread, thereby affecting the actual processing effect; and when merging in the latter stage of the steam process, the towpiece is prone to branching after being wound, and the effect of towpiece merging cannot be guaranteed. SUMMARY

[0006] The embodiment of the application provides a towpiece merging device and method based on a dry-jet wet spinning process, which aims to limit two yarns in the latter stage of the oiling process to realize the technical purpose of towpiece merging.

[0007] To achieve the above purpose, the technical scheme adopted by the application is as follows:

[0008] A towpiece merging device based on a dry-jet wet spinning process is provided, which comprises:

[0009] A substrate is used to be fixed on any mounting surface, the thickness direction of which is defined as the front-rear direction, the width direction is defined as the left-right direction, and the height direction is defined as the up-down direction; and two groups of yarns are arranged side by side on the front side of the substrate along the left-right direction;

[0010] Two groups of gathering assemblies are arranged side by side on the front side of the base plate along the left-right direction and correspond to the two groups of wires respectively; the two groups of gathering assemblies are used to gather the two groups of wires along the front-back direction and the left-right direction respectively to form two strands of the wire bundles;

[0011] Two sliders are arranged side by side on the front side of the base plate along the left-right direction and are slidably connected to the front side of the base plate along the left-right direction, and can be slid to the front side of the two groups of gathering assemblies respectively to make the two strands of the wire bundles fall on the front side of the two sliders respectively; and the front side of each slider is an inclined surface, which is inclined to the rear side along the direction between the two sliders;

[0012] A suction member is arranged on the base plate and is between the two sliders, which is used to generate suction force towards the rear side to provide force for the movement of the wire bundles on the front side of the sliders and make the two strands of the wire bundles falling between the two sliders be adsorbed on the base plate;

[0013] Two groups of wire guide assemblies are arranged on the base plate and are between the gathering assemblies and the sliders, and are located below the two groups of gathering assemblies respectively to pull the wire bundles on the same side to make the wire bundles between the gathering assemblies and the sliders be tightened; and

[0014] A synchronous driving assembly is arranged on the base plate and is in transmission connection with the two sliders and the two groups of wire guide assemblies to drive the two sliders and the two groups of wire guide assemblies simultaneously;

[0015] When the two strands of the wire bundles are between the two sliders, the two strands of the wire bundles can be combined into one strand through the opposite movement of the two sliders;

[0016] The gathering assembly comprises:

[0017] A guide plate is fixedly connected to the front side of the base plate and extends from the rear to the front, and the front part thereof is inclined towards the space between the two groups of gathering assemblies; and

[0018] A sliding seat is slidably connected to the front side of the base plate along the left-right direction and is located behind the inclined part of the guide plate; a baffle is slidably connected to the sliding seat along the front-back direction, and the baffle and the sliding seat have an elastic member therebetween; under the action of the elastic member, the baffle is adapted to move forward to abut against the inclined part of the guide plate; and when the sliding seat moves towards the guide plate, the elastic member is compressed correspondingly;

[0019] The guide plate, the sliding seat and the baffle form a cavity which is open to the up-down direction and is used for placing a group of the yarns; the cavity is reduced by moving the sliding seat towards the guide plate, so as to make the yarns into a bundle; and the two groups of the gathering assemblies are provided with a linear driving assembly which is connected with the two sliding seats and is used for moving the two sliding seats towards or away from the corresponding guide plates at the same time.

[0020] In a possible implementation, the guide wire assembly comprises:

[0021] A rotating arm is arranged on the front side of the base plate, and a transmission shaft is fixedly connected to the middle of the rear side of the rotating arm. The transmission shaft is below the corresponding gathering assembly. The axial direction of the transmission shaft is parallel to the front-rear direction, and the transmission shaft penetrates through the base plate and extends to the rear side of the base plate. The extension end of the transmission shaft is in transmission connection with the synchronous driving assembly. The rotating arm has two strip-shaped holes which are distributed on the two sides of the transmission shaft along the length direction of the rotating arm, and each strip-shaped hole extends along the length direction of the rotating arm.

[0022] Two moving shafts are arranged on the front side of the base plate, and the axial directions of the two moving shafts are parallel to the front-rear direction. The two moving shafts are respectively inserted into the two strip-shaped holes. The two moving shafts are in sliding connection with the front side of the base plate through guide grooves. The guide grooves are arranged on the front side of the base plate, and extend from the position above or below the transmission shaft to the position left or right of the transmission shaft. One end of the guide groove above or below the moving shaft is defined as a first end, and one end of the guide groove left or right of the moving shaft is defined as a second end. The distance between the transmission shaft and the first end is smaller than the distance between the transmission shaft and the second end.

[0023] Two winding rollers are coaxially and rotationally connected to the front ends of the two moving shafts, and the outer peripheral walls of the two winding rollers are used for contacting the yarn bundle.

[0024] When the rotating arm rotates to the length direction and the left-right direction, the two moving shafts are located at the second ends of the guide grooves, so that the yarn bundle can enter between the two winding rollers. At this time, the moving shafts are moved to the first ends of the guide grooves by rotating the rotating arm through the synchronous driving assembly, so that the two winding rollers contact the yarn bundle, and the distance between the two winding rollers is reduced.

[0025] In a possible implementation, the synchronous driving assembly comprises:

[0026] Two gears are coaxially connected to the rear ends of the two transmission shafts.

[0027] Two racks are arranged side by side on the rear side of the base plate in the left-right direction, and are slidably connected to the base plate in the left-right direction, and are respectively engaged with the two gears; and the adjacent side surfaces of the two racks are inclined surfaces, and the inclined surfaces of the two racks are inclined from the bottom to the top towards the space between the two racks;

[0028] A transmission block is slidably connected to the rear side of the base plate in the up-down direction, is located between the two racks, and the left and right sides of the transmission block are respectively in abutment with the adjacent side surfaces of the two racks; the left and right sides of the transmission block are inclined surfaces, and the inclined surfaces of the transmission block are inclined from the top to the bottom towards the corresponding rack; when the transmission block moves from the bottom to the top, the two racks move away from each other;

[0029] A lifting member is slidably connected to the base plate in the up-down direction, is located between the two translation members, and the left and right sides of the lifting member are provided with connecting rods; one end of the connecting rod is hingedly connected to the lifting member in the front-rear direction, and the other end of the connecting rod is hingedly connected to the same side translation member in the front-rear direction; and

[0030] A linear cylinder is fixedly arranged on the rear side of the base plate, and has a drive shaft that can move in the up-down direction and is connected to the transmission block and the lifting member.

[0031] In a possible implementation, the upper and lower ends of the transmission block are provided with resistance blocks that extend outward in the left-right direction, and the lower side surface of the resistance block on the upper side and the upper side surface of the resistance block on the lower side are used to abut against the racks, thereby limiting the movement of the transmission block relative to the racks;

[0032] When each of the movement shafts moves to one of the positions directly above, directly below, directly left, and directly right of the corresponding transmission shaft, one of the resistance blocks abuts against the rack; and the two translation members move away from each other to the left and right sides of the suction member, or the two translation members move towards each other to allow the two strands of the filament bundle to merge into one strand.

[0033] In a possible implementation, a recess is formed in the front side of the base plate, and a filter screen is embedded in the recess; the recess is located between the two translation members, and the bottom of the recess is provided with a plurality of through holes that penetrate to the rear side of the base plate; the suction member is arranged on the rear side of the base plate, and is in communication with the plurality of through holes;

[0034] The two translation members can move away from each other to the two sides of the recess, and can also move towards each other to abut against each other; and when the two translation members abut against each other, the rear side surfaces of the two translation members close the recess.

[0035] In a possible implementation, the suction member comprises:

[0036] The housing, fixedly connected to the rear side of the base plate, has a hollow internal structure and its interior communicates with the plurality of through holes; and

[0037] An air pump, connected to the interior of the housing, is used to expel gas from the housing.

[0038] In one possible implementation, each of the two translational members has a compression pad made of an elastic material on its adjacent side surfaces.

[0039] The side of the extrusion pad facing away from the substrate has an inclined surface. The inclined surface of the extrusion pad is inclined to the rearward in the direction between the two extrusion pads, and the angle between the inclined surface of the extrusion pad and the front side of the substrate is greater than the angle between the inclined surface of the translation member and the front side of the substrate.

[0040] In one possible implementation, the linear drive component includes:

[0041] Two connecting blocks are fixedly connected to the two sliding seats respectively. Both blocks penetrate the base plate and extend to the rear side of the base plate, with their extended portions connected to transmission nuts whose axial direction is parallel to the left-right direction; and

[0042] A double-ended screw is disposed on the rear side of the substrate, its axis is parallel to the left and right direction, and it is rotatably connected to the substrate in the left and right direction; one end of the double-ended screw is connected to a rotary motor for driving it to rotate in the forward or reverse direction.

[0043] The double-ended screw has two connecting parts with opposite thread directions, and the two connecting parts are respectively threaded to the two transmission nuts. When the double-ended screw rotates, the two connecting parts drive the two transmission nuts and the two connecting blocks to move towards each other or away from each other, thereby driving the two sliding seats to move towards or away from the guide plate respectively.

[0044] In this embodiment, a group of threads can be gathered into a single bundle by a gathering component. Furthermore, a suction component moves the bundle between two translational members, which then clamp the bundles together. Additionally, the simultaneous driving effect of the synchronous drive component allows both sets of guide components to operate synchronously, ensuring that both bundles between the translational members and the gathering component are taut, thus preventing curling and splitting when the two bundles merge.

[0045] The yarn bundle merging device based on dry-jet wet spinning process provided in this embodiment, compared with the prior art, limits the two yarns in the later stage of the oiling process, thereby achieving the technical purpose of merging two sets of yarns into one yarn bundle.

[0046] The technical scheme adopted by the present application further provides a tow merging method based on a dry-jet wet spinning process, which applies the tow merging device proposed in any of the foregoing aspects, and comprises the following steps:

[0047] A. By adjusting the position of the traction unit, the two groups of yarns after the oiling process are respectively connected with the two groups of the gathering assemblies and respectively located at the front side of the two translators;

[0048] B. The two groups of the gathering assemblies are started to gather the two groups of the yarns into two tows;

[0049] C. The suction member is started to make the two tows located at the front side of the two translators move along the inclined surface of the translators under the influence of the suction force, so as to enter the area between the two translators;

[0050] D. The synchronous driving assembly is started to start the two groups of the guide assemblies to pull the two tows, so that the part of the tows between the translators and the gathering assemblies is tightened; meanwhile, the two translators are moved towards each other, so that the two tows between the two translators are merged into one.

[0051] The beneficial effects of the tow merging method based on the dry-jet wet spinning process provided by the embodiment are the same as those of the tow merging device based on the dry-jet wet spinning process, which will not be repeated here. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0066] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0067] Please refer to Figures 1 to 13 , the present application provides a silk bundle merging device based on a dry-jet wet spinning process. The silk bundle merging device is arranged at the rear section of an oiling process to load two groups of silk threads after oiling. The structure includes a base plate 1, two folding assemblies 2, two translational members 3, a suction member 4, two guide wire assemblies 5 and a synchronous drive assembly 6.

[0068] The substrate 1 is used to be fixed on any mounting surface after the oiling process, and the thickness direction is defined as the front-rear direction, the width direction is defined as the left-right direction, and the height direction (i.e. the placement direction) is defined as the up-down direction; and the two groups of wires are arranged side by side along the left-right direction on the front side of the substrate 1.

[0069] The two groups of gathering assemblies 2 are arranged side by side along the left-right direction on the front side of the substrate 1, and each corresponds to one group of wires; the two groups of gathering assemblies 2 are used to gather the two groups of wires along the front-rear direction and the left-right direction respectively, so that the two groups of wires are converted into two strands of wire bundles with a smaller total cross-sectional area.

[0070] The two groups of wires are arranged side by side along the left-right direction on the front side of the substrate 1, and each corresponds to one group of wires; the two groups of gathering assemblies 2 are used to gather the two groups of wires along the front-rear direction and the left-right direction respectively, so that the two groups of wires are converted into two strands of wire bundles with a smaller total cross-sectional area.

[0071] In this embodiment, the front side of each translating member 3 is an inclined surface, and the inclined surface of the translating member 3 inclines to the rear side along the direction towards the space between the two translating members 3; for ease of description, the side facing each other of the two translating members 3 is defined as the inner side of each translating member 3, and the side facing away from each other of the two translating members 3 is defined as the outer side of each translating member 3, and the inclined surface of the aforementioned translating member 3 inclines to the rear side from the outer side to the inner side.

[0072] The suction member 4 is arranged on the substrate 1 and is located between the two translating members 3, and is used to generate a suction force towards the rear side; when the wire bundles fall on the front side of the translating member 3, the suction member 4 provides an inward movement force for the wire bundles on the front side of the translating member 3, and makes the two strands of wire bundles falling between the two translating members 3 adsorb to the substrate 1, completing the final positioning of the two strands of wire bundles before merging into one strand. When the two strands of wire bundles are between the two translating members 3 (i.e. the aforementioned final positioning is completed), the two strands of wire bundles can be merged into one strand by moving the two translating members 3 towards each other.

[0073] The two groups of wire guide assemblies 5 are arranged on the substrate 1 and are located between the gathering assembly 2 and the translating member 3, and are respectively located below the two groups of gathering assemblies 2, so as to pull the wire bundles on the same side, so as to tighten the wire bundles between the gathering assembly 2 and the translating member 3; specifically, when the two strands of wire bundles complete the aforementioned final positioning, the wire guide assembly 5 can act to tighten the gathering assembly 2, so as to avoid the occurrence of rolling, branching and other adverse phenomena when the wire bundles are merged.

[0074] The synchronous drive component 6 is mounted on the base plate 1 and is connected to the two translational members 3 and the two sets of wire guide assemblies 5 for transmission, so as to drive the two translational members 3 and the two sets of wire guide assemblies 5 simultaneously. That is to say, the two translational members 3 move towards each other and the wire guide assembly 5 is tightened at the same time. This can maximize the processing efficiency of the device and minimize the cost of the drive components, so that the product can achieve energy saving and low cost while ensuring the degree of automation.

[0075] In this embodiment, the gathering component 2 can gather a group of threads into a single bundle; based on this, the suction component 4 can move the bundle between the two translational components 3, and then the clamping of the two translational components 3 can merge the two bundles into one; based on this, the simultaneous driving effect of the synchronous driving component 6 can make the two sets of guide components 5 work synchronously, so that the two bundles between the translational components 3 and the gathering component 2 are both in a taut state, thereby avoiding the phenomenon of curling and splitting when the two bundles are merged into one.

[0076] The yarn bundle merging device based on dry-jet wet spinning process provided in this embodiment, compared with the prior art, limits the two yarns in the later stage of the oiling process, thereby achieving the technical purpose of merging two sets of yarns into one yarn bundle.

[0077] In some embodiments, such as Figure 2 , Figure 7 and Figure 8 As shown, the wire guide assembly 5 includes a rotating arm 51, two moving shafts 52 and two winding rollers 53.

[0078] A rotating arm 51 is disposed on the front side of the substrate 1. It has a structure that extends in a straight line and its length direction is perpendicular to the front-rear direction. A drive shaft 511 is fixedly connected to the middle of the rear side of the rotating arm 51. The axis of the drive shaft 511 is parallel to the front-rear direction, and it passes through the substrate 1 and extends to the rear side of the substrate 1 to realize the rotational connection between the rotating arm 51 and the substrate 1. Furthermore, the extended end of the drive shaft 511 is connected to the aforementioned synchronous drive assembly 6 to realize kinetic energy drive. In terms of spatial position, this drive shaft 511 is located directly below the corresponding (same side) gathering assembly 2, so that when the wire is loaded on the gathering assembly 2, the lower part of the wire is on the front side of the rotating arm 51.

[0079] In this embodiment, the rotating arm 51 has two strip holes 512; the two strip holes 512 are distributed at intervals on both sides of the transmission shaft 511 along the length direction of the rotating arm 51, and each strip hole 512 extends along the length direction of the rotating arm 51.

[0080] The two moving shafts 52 are arranged on the front side of the base plate 1, the axial directions of the two moving shafts 52 are parallel to the front-rear direction, and the two moving shafts 52 are respectively inserted into the two strip-shaped holes 512; and the two moving shafts 52 are further respectively connected to the front side of the base plate 1 in a sliding manner through the guide grooves 11; that is, each guide groove 11 is arranged on the front side of the base plate 1, and extends from the position directly above or directly below the transmission shaft 511 to the position directly left or directly right of the transmission shaft 511, and the end of the guide groove 11 directly above or directly below the moving shaft 52 is defined as a first end, and the end of the guide groove 11 directly left or directly right of the moving shaft 52 is defined as a second end; in this embodiment, the distance between the transmission shaft 511 and the first end is less than the distance between the transmission shaft 511 and the second end.

[0081] In this embodiment, as shown in Figure 3 , the two groups of guide wire assemblies 5 correspond to the four moving shafts 52, and the corresponding guide grooves 11 also have four guide grooves; according to the classification of the groups, the two guide grooves 11 corresponding to the first group of guide wire assemblies 5 are respectively arranged from the position directly above the moving shaft 52 to the position directly right of the moving shaft 52, and from the position directly below the moving shaft 52 to the position directly left of the moving shaft 52; the two guide grooves 11 corresponding to the second group of guide wire assemblies 5 are respectively arranged from the position directly above the moving shaft 52 to the position directly left of the moving shaft 52, and from the position directly below the moving shaft 52 to the position directly right of the moving shaft 52.

[0082] The two winding rollers 53 are coaxially and rotationally connected to the front ends of the two moving shafts 52, and the outer circumferential walls of the two winding rollers 53 are used to contact the wire bundle.

[0083] By adopting the above technical scheme, when the rotating arm 51 is rotated to be parallel to the length direction and the left-right direction, the two moving shafts 52 are located at the second ends of the guide grooves 11, at this time, the distance between the two winding rollers 53 is large, so that the wire bundle on the same side can enter between the two winding rollers 53; at the same time, the synchronous driving assembly 6 drives the two rotating arms 51 to rotate in opposite directions, so that the moving shafts 52 move to the first ends of the guide grooves 11, so that the distance between the two winding rollers 53 is reduced, and then the two winding rollers 53 contact the wire bundle; since the first end of the guide groove 11 is directly above or directly below the transmission shaft 511, at this time, the winding roller 53 can twist the contacted wire bundle into an S shape, so as to achieve the technical purpose of tightening the wire bundle.

[0084] In some embodiments, as shown in Figure 4 , Figures 7 to 10 , the synchronous driving assembly 6 includes two gears 61, two racks 62, a transmission block 63, a lifting piece 64 and a linear cylinder 65.

[0085] The two gears 61 are coaxially connected to the rear ends of the two transmission shafts 511 respectively, and the central axes of the two gears 61 are located on the same horizontal plane.

[0086] Two racks 62 are arranged side by side on the rear side of the base plate 1 in the left-right direction, and are in sliding connection with the base plate 1 in the left-right direction, and are respectively engaged with the two gears 61. In the embodiment, the adjacent side surfaces of the two racks 62 are closed inclined surfaces, and the inclined surfaces of each rack 62 are inclined from bottom to top towards the direction between the two racks 62.

[0087] The transmission block 63 is in sliding connection with the rear side of the base plate 1 in the up-down direction, is between the two racks 62, and the left and right sides thereof are respectively in abutment with the adjacent side surfaces of the two racks 62; the left and right sides of the transmission block 63 are both inclined surfaces, and the inclined surfaces of the transmission block 63 are inclined from top to bottom towards the corresponding rack 62. The technical purpose of this design is that when the transmission block 63 moves from bottom to top, the two racks 62 can move in the opposite direction.

[0088] The lifting member 64 is in sliding connection with the base plate 1 in the up-down direction, is between the two translating members 3, and the left and right sides thereof both have connecting rods 641; one end of the connecting rod 641 is hingedly connected with the lifting member 64 in the front-rear direction, and the other end thereof is hingedly connected with the same side translating member 3 in the front-rear direction.

[0089] The linear cylinder 65 is fixedly arranged on the rear side of the base plate 1, and has a drive shaft 651 which can move in the up-down direction and is connected with the transmission block 63 and the lifting member 64.

[0090] By adopting the above technical scheme, when the linear cylinder 65 is started, the drive shaft 651 can move upwards to drive the transmission block 63 to move the two racks 62 in the opposite direction, thereby driving the two gears 61 to rotate in the opposite direction, completing the driving of the two rotating arms 51 to rotate in the opposite direction; at the same time, the lifting member 64 moves upwards, thereby driving the two connecting rods 641 to swing, so that the two translating members 3 move towards each other, so that the two strands of silk strands positioned between the two translating members 3 are combined into one strand.

[0091] It needs to be specially pointed out that when the driving shaft 651 moves downward, the two sliders 3 will move away from each other, and the two racks 62 will not move towards each other; that is, the gear 61 and the related rotating arm 51 will not rotate (compared to the state when the transmission block 63 and the rack 62 abut, at this time the rotating arm 51 will only loosen under the traction of the wire bundle, thereby making the tightening effect of the related wire bundle worse); by such design, the reciprocating movement of the driving shaft 651 can realize the manufacturing of the bendable single wire bundle. The bendable single wire bundle refers to a plurality of wire bundles (after merging) that are spaced apart in the length direction of the wire bundle, and the part between the adjacent two wire bundles is in the state between the wire and the wire bundle (this is due to the fact that the wire bundle effect formed by the folding assembly 2 is not tightened in the subsequent processing, resulting in a decrease in the folding effect), which can realize the connection and bending between the adjacent two wire bundles, and can also ensure that the wire bundle connection part will not be deformed radially.

[0092] In actual processing, if the two racks 62 need to be reset, human intervention is required, specifically moving the two racks 62 towards each other when the wire bundle is unloaded; or a torsional spring that can drive the rack 62 to automatically reset can be arranged on the transmission shaft 511, so that when the transmission block 63 and the rack 62 are separated, the transmission shaft 511 quickly resets to the horizontal state of the rotating arm 51, thereby driving the rack 62 to move towards the area between the two racks 62, ensuring timely abutment of the rack 62 and the transmission block 63. However, since the process of resetting the rack 62 is less important in actual operation, and human-driven resetting has good controllability in actual operation, therefore, in this embodiment, no complex structure design is made at this point.

[0093] In some embodiments, as shown in Figure 4 and Figure 9 The upper and lower ends of the transmission block 63 both have blocking blocks 631 extending outward in the left-right direction, and the lower side of the blocking block 631 on the upper side and the upper side of the blocking block 631 on the lower side are used to abut with the rack 62, thereby limiting the movement of the transmission block 63 relative to the rack 62.

[0094] By adopting the above technical scheme, when each moving shaft 52 moves to one of the positions directly above, directly below, directly left and directly right of the corresponding transmission shaft 511, one of the blocking blocks 631 abuts with the rack 62; at the same time, the two sliders 3 move away from each other to the left and right sides of the suction member 4, or the two sliders 3 move towards each other to a position where the two wire bundles can be merged into one.

[0095] In some embodiments, as shown in Figure 12As shown, the front side of the substrate 1 is provided with a groove 12, and the filter screen 7 is embedded in the groove 12; the groove 12 is between the two sliding members 3, and the groove bottom of the groove 12 is provided with a plurality of through holes 13 penetrating to the rear side of the substrate 1; the suction member 4 is arranged on the rear side of the substrate 1, and it communicates with the plurality of through holes 13.

[0096] In actual use, the two sliding members 3 can move away from each other to the two sides of the groove 12 (so that the suction of the suction member 4 can fully play a role), and they can also move towards each other to abut against each other; and when the two sliding members 3 abut against each other, the rear side of the two sliding members 3 closes the groove 12 (so as to avoid the suction of the suction member 4 from interfering with the merging of the filaments).

[0097] It should be noted that, in order to avoid the suction of the suction member 4 from interfering with the merging of the filaments, the suction member 4 can also be directly closed, and the above-mentioned manner is designed to avoid the interference effect caused by the suction of the suction member 4 not being timely removed.

[0098] In some embodiments, as shown in Figure 4 , the suction member 4 includes a box body 41 and a gas pump 42.

[0099] The box body 41 is fixedly connected to the rear side of the substrate 1, and it adopts a hollow structure, and its inside communicates with the plurality of through holes 13.

[0100] The gas pump 42 communicates with the inside of the box body 41, so as to exhaust the gas in the box body 41, so as to form a local negative pressure environment in the box body 41.

[0101] In some embodiments, as shown in Figure 3 and Figure 13 , the adjacent side surfaces of the two sliding members 3 are each provided with a pressing pad 31 made of elastic material.

[0102] Among them, the side of the pressing pad 31 away from the substrate 1 adopts an inclined surface, the inclined surface of the pressing pad 31 inclines to the rear side along the direction between the two pressing pads 31, and the angle between the inclined surface of the pressing pad 31 and the front side of the substrate 1 is greater than the angle between the inclined surface of the sliding member 3 and the front side of the substrate 1, so as to avoid the filaments staying in front of the pressing pad 31 which is softer than the sliding member 3.

[0103] In some embodiments, as shown in Figure 2 , Figure 5 and Figure 6 , the folding assembly 2 includes a guide plate 21 and a sliding seat 22.

[0104] The guide plate 21 is fixedly connected to the front side of the substrate 1, and it extends from rear to front, and the front part adopts an inclined structure towards between the two groups of folding assemblies 2.

[0105] The sliding seat 22 is slidably connected to the front side of the base plate 1 along the left-right direction and is located right behind the inclined portion of the guide plate 21; a baffle 221 is slidably connected to the sliding seat 22 along the front-rear direction, and the baffle 221 and the sliding seat 22 are provided with an elastic member 222; under the action of the elastic member 222, the baffle 221 is adapted to move forward to abut against the inclined portion of the guide plate 21, thereby achieving the following technical purpose: when the sliding seat 22 moves towards the guide plate 21, the elastic member 222 is correspondingly compressed to ensure that the baffle 221 always maintains the position state of abutting against the guide plate 21, thereby forming a cavity with the guide plate 21, the sliding seat 22 and the baffle 221, which is open to the up-down direction and is used for placing a group of threads.

[0106] In the embodiment, a single linear drive assembly 8 is arranged between the two groups of folding assemblies 2 for the purposes of reducing the manufacturing cost of the device and ensuring that the two groups of folding assemblies 2 work simultaneously; the linear drive assembly 8 is connected to the two sliding seats 22 for simultaneously driving the two sliding seats 22 to move towards or away from the corresponding guide plates 21.

[0107] When the threads are loaded, the two sliding seats 22 are first moved away by the linear drive assembly 8 to a relatively far position, so that the aforementioned cavity is as large as possible to facilitate the placement of a single group of threads; after the threads are placed in the aforementioned cavity, the two sliding seats 22 are simultaneously moved towards the corresponding guide plates 21 by the linear drive assembly 8, so that the aforementioned cavity is reduced, and the threads are folded and merged into a bundle.

[0108] In some embodiments, as shown in Figure 4 and Figure 11 , the linear drive assembly 8 includes two connecting blocks 81 and a double-headed screw 82.

[0109] The two connecting blocks 81 are fixedly connected to the two sliding seats 22 respectively, and each of them penetrates through the base plate 1 and extends to the back side of the base plate 1, and the extending part is connected with a transmission nut 811 whose axis is parallel to the left-right direction.

[0110] The double-headed screw 82 is arranged on the back side of the base plate 1, and its axis is parallel to the left-right direction, and it is rotatably connected to the base plate 1 along the left-right direction; and one end of the double-headed screw 82 is connected with a rotating motor 821 for driving it to rotate forward or reverse.

[0111] In the embodiment, the double-headed screw 82 has two connecting parts with opposite thread directions, and the two connecting parts are threadedly connected with the two transmission nuts 811 respectively.

[0112] By adopting the above technical scheme, when the double-head screw rod 82 rotates, the two connecting portions drive the two transmission nuts 811 and the two connecting blocks 81 to move towards or away from each other, and then drive the two sliding seats 22 to move towards or away from the guide plate 21, respectively.

[0113] Based on the same inventive concept, the application further provides a method for merging filaments based on the dry-jet wet spinning process, which applies the filament merging device proposed in any of the preceding embodiments, and comprises the following steps:

[0114] A. By adjusting the position of the traction unit, the two groups of filaments after the oiling process are respectively connected to the two groups of gathering assemblies 2 and respectively located at the front side of the two translators 3;

[0115] B. Start the two groups of gathering assemblies 2 to gather the two groups of filaments into two strands of filaments;

[0116] C. Start the suction member 4 to make the two strands of filaments located at the front side of the two translators 3 move along the inclined surface of the translator 3 under the influence of the suction force, so as to enter the area between the two translators 3;

[0117] D. Start the synchronous driving assembly 6 to start the two groups of guide filament assemblies 5 to pull the two strands of filaments, so that the part of the filaments between the translator 3 and the gathering assembly 2 is tightened; at the same time, the two translators 3 move towards each other, and then the two strands of filaments between the two translators 3 are merged into one strand.

[0118] The method for merging filaments based on the dry-jet wet spinning process provided in the embodiment has the same beneficial effects as the filament merging device based on the dry-jet wet spinning process, which will not be repeated here.

[0119] The above is only a preferred embodiment of the present application, and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
