Description

Technical Field

[0001] This utility model relates to the field of chemical fiber textile equipment technology, specifically to a nylon 66 mother yarn splitting device. Background Technology

[0002] Nylon 66 is a high-performance synthetic fiber. Its chemical name is polyhexamethylene adipamide, formed by the condensation polymerization of adipic acid and hexamethylenediamine monomers. Its molecular backbone contains 66 carbon atoms, hence its name. Nylon 66 possesses excellent properties such as high strength, high abrasion resistance, and high temperature resistance, and is mainly used in tires, seat belts, industrial ropes, conveyor belts, high-end clothing, and carpets.

[0003] Nylon 66 masterfilament is composed of multiple monofilaments, which are separated into individual fibers for subsequent processing. The masterfilament separation process of nylon 66 mainly involves cutting raw materials, melt extrusion, spinning, drawing and setting, and winding into a tube to obtain the masterfilament product. The masterfilament product is then separated into multiple independent monofilament finished products by a fiber separator.

[0004] For example, molten nylon 66 raw material is extruded through the spinneret of the spinning assembly. After spinning and setting, a single master filament can be split into twelve individual fibers. Since the fineness of a single fiber is relatively coarse, a fiber splitter is needed for better fiber splitting. Figures 1 to 3 The filament separator 2 is toothed. The mother filament 1 passes through the oil roller 3 of the oiling device and the V-shaped tooth groove 21 of the filament separator 2 in sequence. One single filament 11 passes through one V-shaped tooth groove 21. The groove wall of the V-shaped tooth groove 21 is an inclined structure that widens outward. Because the single filament is relatively thick, it is affected by tension fluctuations and wind speed during operation. This can easily cause the single filament to jump left and right and slide out of the V-shaped tooth groove of the filament separator, resulting in two single filaments jumping together and causing filament merging. It is difficult to perform stable filament separation, which affects the uniform oiling of the single filament on the oil roller, thus leading to filament breakage and dyeing problems in subsequent processing.

[0005] Therefore, how to effectively avoid fiber fusion and improve the stability of fiber splitting is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a nylon 66 mother yarn splitting device, which effectively avoids yarn tangling and improves the stability of yarn splitting.

[0007] The technical solution of this utility model is achieved as follows: a nylon 66 mother yarn splitting device, including a splitting assembly, a connecting shaft, a separator block, a first limiting block, a second limiting block, and a locking rod; The wire splitting assembly includes a sleeve and a wire separator disc. The center of the wire separator disc is fixedly connected to the sleeve. Multiple wire separator discs are evenly spaced along the length of the sleeve. The disc surface of the wire separator disc is perpendicular to the central axis of the sleeve. A wire groove is formed between two adjacent wire separator discs. The right end of the connecting shaft has a first locking through hole, and the first limiting block is fixedly disposed on the outer surface of the connecting shaft. The first limiting block is also adjacent to the first locking through hole. The connecting shaft passes through the tube hole of the sleeve, the partition block has a sliding hole, the connecting shaft also passes through the sliding hole, there are multiple wire splitting assemblies, and a partition block is provided between two adjacent wire splitting assemblies; The second limiting block is fixedly connected to the right end of the locking rod, the left end of the locking rod has a second locking through hole, the left end of the connecting shaft is locked to the right end of the locking rod by a thread, the rightmost wire splitting assembly abuts against the first limiting block, and the leftmost wire splitting assembly abuts against the second limiting block.

[0008] Furthermore, the edge of the wire separator disc is provided with hook-shaped wire-blocking blocks.

[0009] Furthermore, it also includes a first support base, a second support base, a first bolt, a second bolt, and a frame. The first support base is fixedly disposed at the right end of the frame, and the second support base is fixedly disposed at the left end of the frame. The first bolt passes through the first locking through hole and is fixedly connected to the first support base. The second bolt passes through the second locking through hole and is fixedly connected to the second support base. The connecting shaft is located below the oil roller.

[0010] Furthermore, the filament splitting assembly is a filament splitting assembly made of ceramic.

[0011] Furthermore, there are three wire splitting assemblies, and each wire splitting assembly has six wire grooves.

[0012] Compared with the prior art, the beneficial effects or advantages of this utility model are as follows: During the wire splitting process, the single wire passes through the wire groove between two adjacent wire separators. Since the surface of the wire separator is perpendicular to the central axis of the sleeve, the single wire jumping left and right is blocked in the wire groove when it encounters the surface of the wire separator, thus effectively preventing the single wire from slipping out of the wire groove and causing two single wires to jump together and become tangled; the number of wire splitting components can be assembled according to the actual production quantity of the mother wire, and the separator block plays the role of separating the wire splitting components, which helps to prevent the single wires of adjacent mother wires from becoming tangled; the connecting shaft, locking rod, wire splitting components, and separator block are easy to disassemble and assemble, and when the first locking through hole and the second locking through hole are both fixed to the support base with bolts, it can effectively prevent the connecting shaft and the locking rod from rotating loosening, which helps to improve the structural firmness of the wire splitting device of this utility model; and improve the stability of wire splitting.

[0023] This utility model provides a nylon 66 filament splitting device to address the shortcomings described in the prior art, namely, that the filaments in the splitter are prone to lateral movement due to tension fluctuations and wind speed, resulting in filaments slipping out of the V-shaped groove and two filaments jumping together, causing filament tangling. The overall concept of the technical solution adopted in this utility model is as follows: Regarding the toothed filament splitter of the prior art, although toothed racks are readily available, the walls of the V-shaped grooves on the racks are inclined structures that widen outwards, making it easy for laterally moving filaments to slip out when encountering the groove walls. This utility model improves upon this by including a splitting assembly, a connecting shaft, a separator block, a first limiting block, a second limiting block, and a locking rod. The splitting assembly includes a sleeve and a spacer disc, the surface of which is perpendicular to the central axis of the sleeve, with multiple spacer discs evenly spaced. The system consists of a wire groove formed between two adjacent wire separating discs, a wire splitting assembly for splitting a single mother wire, a connecting shaft connecting multiple wire splitting assemblies and separator blocks, and a locking rod connected by a threaded lock. A first and second limiting block clamp the wire splitting assembly from both sides. By fixing the first locking through-hole of the connecting shaft and the second locking through-hole of the locking rod, rotational loosening between the connecting shaft and the locking rod is prevented, improving structural robustness. Multiple mother wires are split on multiple wire splitting assemblies. A single wire passes through the wire groove between two adjacent wire separating discs, close to the sleeve. When the single wire is affected by tension fluctuations and wind speed, the jumping left and right single wire is blocked in the wire groove upon encountering the surface of the wire separating disc, effectively preventing the single wire from slipping out of the wire groove and causing two single wires to jump together and become tangled. This invention improves the stability of wire splitting, helps the single wires of multiple mother wires to be distributed on the oil roller of the oiling device, ensuring that each single wire is fully and evenly oiled, thus improving quality.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] See Figures 1 to 8 The preferred embodiment of this utility model.

[0026] A nylon 66 mother yarn splitting device includes a splitting assembly 4, a connecting shaft 5, a separator block 6, a first limiting block 7, a second limiting block 8, and a locking rod 9; The wire splitting assembly 4 includes a sleeve 41 and a wire separator 42. The center of the wire separator 42 is fixedly connected to the sleeve 41. Multiple wire separators 42 are evenly spaced along the length of the sleeve 41. The surface of the wire separator 42 is perpendicular to the central axis of the sleeve 41. A wire groove 421 is formed between two adjacent wire separators 42. The right end of the connecting shaft 5 has a first locking through hole 51, and the first limiting block 7 is fixedly disposed on the outer surface of the connecting shaft 5. The first limiting block 7 is also adjacent to the first locking through hole 51. The connecting shaft 5 passes through the tube hole of the sleeve 41, the partition block 6 has a sliding hole, the connecting shaft 5 also passes through the sliding hole, there are multiple wire splitting assemblies 4, and a partition block 6 is provided between two adjacent wire splitting assemblies 4; The second limiting block 8 is fixedly connected to the right end of the locking rod 9. The left end of the locking rod 9 has a second locking through hole 91. The left end of the connecting shaft 5 is locked to the right end of the locking rod 9 by a thread. The rightmost wire splitting assembly 4 abuts against the first limiting block 7, and the leftmost wire splitting assembly 4 abuts against the second limiting block 8.

[0027] The beneficial effects or advantages of this utility model are as follows: During the wire splitting process, the single wire 11 passes through the wire groove 421 between two adjacent wire separators 42. Since the surface of the wire separator 42 is perpendicular to the central axis of the sleeve 41, the single wire 11 jumping left and right is blocked in the wire groove 421 when it encounters the surface of the wire separator 42, thus effectively preventing the single wire 11 from slipping out of the wire groove 421 and forming two single wires 11 jumping together and causing wire bridging; the number of wire splitting components 4 can be assembled according to the actual number of mother wires 1 produced. The separator block 6 plays a significant role in separating the wire splitting components 4, which helps to prevent the single wires 11 of adjacent mother wires 1 from bridging; the connecting shaft 5, locking rod 9, wire splitting components 4, and separator block 6 are easy to disassemble and assemble. When the first locking through hole 51 and the second locking through hole 91 are both fixed to the support base with bolts, it can effectively prevent the connecting shaft 5 and the locking rod 9 from rotating loosening, which helps to improve the structural firmness of the wire splitting device of this utility model; and improve the stability of wire splitting.

[0028] First, assemble the nylon 66 mother yarn splitting device of this utility model. Based on the number of single filaments 11 to be split from a single mother yarn 1 produced in actual production, select a splitting assembly 4 with a corresponding number of grooves. Based on the number of mother yarns 1 produced, set the number of splitting assemblies 4 used and select appropriate length partition blocks 6. Connect the splitting assemblies 4 and partition blocks 6 together via a connecting shaft 5. The first limiting block 7 on the connecting shaft 5 is close to the rightmost splitting assembly 4. The partition blocks 6 are used to ensure that the position of the splitting assembly 4 corresponds to the position of the mother yarn 1, allowing workers to clearly see the mother yarns 1 in different positions through the partition blocks 6. The left end of the connecting shaft 5 has an external thread, and the right end of the locking rod 9 has an internal thread hole. The connecting shaft 5 and the locking rod 9 are locked together by threads. The first limiting block 7 is close to the rightmost splitting assembly 4, and the second limiting block 8 is close to the leftmost splitting assembly 4. For example, the spacer disc 42 is a circular disc; the distance between two adjacent spacer discs 42 is two millimeters.

[0029] The nylon 66 mother yarn splitting device of this invention is then installed on the mother yarn splitting machine. The first locking through hole 51 of the connecting rod and the second locking through hole 91 of the locking rod 9 are both fixedly connected to the frame. The single filament 11 split from the mother yarn 1 is tangent to the wheel surface of the oil roller 3 of the oiling device. The single filament 11 then passes through the filament groove 421 of the corresponding splitting component 4. The single filament 11 is close to the sleeve 41. During the production process, when the single filament 11 is affected by tension fluctuations and wind speed, the single filament 11 that jumps left and right is blocked in the filament groove 421 when it encounters the vertical plate surface of the separator 42, thereby effectively preventing the single filament 11 from slipping out of the filament groove 421 and forming two single filaments 11 jumping together and causing yarn tangling. This invention improves the stability of yarn splitting and helps the single filaments 11 of multiple mother yarns 1 to be distributed on the oil roller 3 of the oiling device, so that each single filament 11 is fully and evenly oiled, improving quality. It effectively prevents yarn breakage and dyeing problems in subsequent processing.

[0030] Furthermore, the edge of the wire separator disc 42 is provided with a hook-shaped wire-blocking block 43.

[0031] The beneficial effects of this technical solution are as follows: the hook-shaped wire-blocking block 43 makes the opening of the wire groove 421 have a structure that is narrow on the outside and wide on the inside. During the preparation stage, the operator operates the monofilament 11 to enter the wire groove 421 through the middle gap of the opening. During the production stage, when the monofilament 11 is affected by large-amplitude tension fluctuations and wind speed, the hook-shaped wire-blocking block 43 effectively prevents the jumping monofilament 11 from falling out of the opening, thereby improving the stability of the monofilament 11 in the wire groove 421.

[0032] The left and right sides of the wire separator 42 are equipped with hook-shaped wire-blocking blocks 43; the slots between two adjacent wire separators 42 are blocked by two hook-shaped wire-blocking blocks 43, forming a gap between the two hook-shaped wire-blocking blocks 43. On the left side of the wire separator 42, there are two centrally symmetrical hook-shaped wire-blocking blocks 43; on the right side of the wire separator 42, there are also two centrally symmetrical hook-shaped wire-blocking blocks 43; this facilitates the operator in selecting the position of the hook-shaped wire-blocking blocks 43 through which the monofilament 11 passes according to actual needs.

[0033] Furthermore, it also includes a first support base 10, a second support base 20, a first bolt 30, a second bolt 40, and a frame. The first support base 10 is fixedly disposed at the right end of the frame, and the second support base 20 is fixedly disposed at the left end of the frame. The first bolt 30 passes through the first locking through hole 51 and is locked to the first support base 10. The second bolt 40 passes through the second locking through hole 91 and is locked to the second support base 20. The connecting shaft 5 is located below the oil roller 3.

[0034] The beneficial effects of this technical solution are: the first bolt 30 and the second bolt 40 facilitate assembly and disassembly by workers; the first bolt 30 passes through the first locking through hole 51 in the vertical direction to fix the connecting shaft 5 to the first support seat 10, and the second bolt 40 passes through the second locking through hole 91 in the vertical direction to fix the locking rod 9 to the second support seat 20. At this time, it prevents the external thread of the connecting shaft 5 and the internal thread hole of the locking rod 9 from rotating and loosening, thereby improving the structural firmness.

[0035] Furthermore, the filament splitting assembly 4 is a filament splitting assembly made of ceramic.

[0036] The beneficial effects of this technical solution are: the ceramic material surface is smooth, and with the oiling agent of the oiling device, the friction of the single filament 11 is reduced during the filament separation process.

[0037] Furthermore, there are three filament splitting components, each with six filament grooves. Alternatively, there can be six filament splitting components, each with twelve filament grooves; that is, six master filaments can be split simultaneously, with each master filament split into twelve monofilaments; a total of seventy-two monofilaments are obtained. For example, if a master filament has a specification of 240D / 12F, after splitting, twelve 20D monofilaments are obtained, which can be used to make high-grade knitted fabrics.

[0038] The nylon 66 filament splitting device of this utility model not only effectively prevents the single filament 11 from slipping out of the filament groove 421 and causing two single filaments to jump together and cause filament tangling, thus improving the stability of filament splitting, but also helps the single filaments to be evenly distributed on the oil roller 3 of the oiling device for oiling. The number of filament splitting components 4 can also be selected. By selecting the separator blocks 6 of different lengths, the spacing between two adjacent filament splitting components 4 can be changed to match the actual position of the filament. The filament splitting components 4 and the separator blocks 6 are connected in series by the connecting shaft 5. The connecting shaft 5 is then locked and fixed to the locking rod 9 by threads. The first limiting block 7 and the second limiting block 8 play the role of clamping the filament splitting components 4 from the left and right sides, making disassembly and assembly convenient.

[0039] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
