Description

[0002] Ultra-high molecular weight polyethylene (UHMWPE) fiber is a synthetic fiber material with special properties. UHMWPE fiber is prepared by polymerizing ethylene monomers. It has a very high molecular weight and long chain structure, and has excellent comprehensive performance. It is one of the important choices in many high-performance fiber applications. UHMWPE fiber is widely used in safety protection, marine engineering, sporting goods and other industries, such as in the manufacture of bulletproof vests, protective gloves, cables, ship ropes, sports equipment and other products.

[0003] At present, UHMWPE fibers are usually prepared by gel spinning technology. Specifically, in the pre-spinning stage of gel spinning technology, the raw materials are made into spinning solution, and the spinning solution is melted and extruded through equipment such as a twin-screw extruder to obtain gel filaments with a certain diameter and shape. In the post-spinning stage of gel spinning technology, the gel filaments enter the bundling device for bundling treatment to arrange the fibers in an orderly manner to prevent crossing and entanglement between the fibers. Then, heat treatment is performed, such as heat setting and multi-stage heat drawing treatment, to improve the orientation and crystallinity of the fibers and enhance their mechanical properties. Then, extraction is performed with a specific solvent to remove the solvent in the gel filaments, and then a series of drying treatments are performed to remove the residual solvent to obtain the finished UHMWPE fiber.

[0004] However, even if a bundling device is provided in the post-spinning stage in the prior art, fibers may still be doubly connected, and the fibers that should have been independent may be partially adhered, interwoven or entangled with each other, making the post-spinning production process difficult and increasing the workload of operators.

[0005] Therefore, a bundling device for post-spinning ultra-high molecular weight polyethylene fibers having a better anti-dual-filament effect is needed. Utility Model Content

[0030] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0031] like Figure 1-2 As shown, the utility model provides a bundling device for ultra-high molecular weight polyethylene fibers, comprising a support frame 9, a guide assembly and at least one bundling frame.

[0032] The clustering frame of the utility model comprises a wire support rod 2, a wire separation rod 3 and a liquid receiving assembly 5. The function of the clustering frame is to cluster the jelly wires 7 so that the jelly wires 7 are arranged in an orderly manner to prevent the jelly wires 7 from sticking, crossing and entanglement. Since the jelly wires 7 may have different lengths, one or more clustering frames can be selected and set according to actual conditions in the utility model so as to adapt to the length of the jelly wires 7 to be clustered.

[0033] Among them, the wire support rod 2, the wire separation rod 3 and the guide assembly are respectively arranged on the support frame 9, and the liquid receiving assembly 5 is located below the wire separation rod 3, which is used to receive the solvent dripping from the jelly thread 7 to avoid contaminating the factory floor. With the movement direction of the jelly thread 7 as the front end, the guide assembly is arranged at the front end of the clustering frame, which is used to drive the jelly thread 7 to move along the clustering device for wire separation processing, and then enter the hot stretching device for post-spinning processing for hot stretching processing, etc. In the utility model, a plurality of wire separation forks 4 are arranged on the wire separation rod 3, and each wire separation fork 4 has a certain distance between them, and the plurality of wire separation forks 4 are preferably evenly distributed on the wire separation rod 3.

[0034] The utility model provides at least two support rods 2 at the rear end of the branching rod 3. Figure 1 As shown, adjacent jelly threads 7 can cross through different support rods 2 in an interlaced manner, wherein the jelly threads 7 cross through different support rods 2 as shown in that the first jelly thread 7 passes from the bottom of the first support rod, then passes from the top of the second support rod, passes from the bottom of the third support rod, passes from the top of the fourth support rod, and so on. The jelly thread 7 adjacent to the first jelly thread 7 passes from the top of the first support rod, then passes from the bottom of the second support rod, passes from the top of the third support rod, passes from the bottom of the fourth support rod, and so on. Therefore, in the utility model, before entering the wire splitting rod 3 for wire splitting, the jelly thread 7 can cross multiple wire support rods 2 in an interlaced manner through different paths, which can effectively increase the distance between the jelly threads 7. Therefore, the utility model avoids the mutual adhesion and entanglement of the jelly threads 7 by setting at least two wire support rods 2, can significantly reduce the problem of doubling, is beneficial to the post-spinning production of fibers, can reduce the workload of operators, and improve production efficiency.

[0035] In addition, the support rod 2 in the utility model can not only prevent the wire from being twisted, but also play a basic supporting role for the long-length jelly wire 7 to prevent the jelly wire 7 from sagging.

[0036] Overall, the utility model uses the wire support rod 2 in the clustering frame to allow the jelly yarn 7 to enter the wire separation rod 3 and cross different wire support rods 2 to prevent the wire from being combined. In the utility model, the wire separation rod 3 and the wire separation fork 4 on the wire separation rod 3 can separate the jelly yarn 7, the liquid receiving component 5 under the wire separation rod 3 can receive the solvent dripping from the jelly yarn 7 to avoid contamination, and the guide component can drive the jelly yarn 7 to move along the clustering device, and then enter the hot drawing component for subsequent post-spinning processing.

The jelly wires 7 in the wire barrel 1 are directly interlaced and interspersed on the wire support rod 2 from the wire barrel 1.

[0038] Preferably, the guide assembly in the present invention comprises an active roller 8 and a guide roller 6, and the active roller 8 and the guide roller 6 are respectively arranged on a support frame 9.

[0040] Preferably, in order to enable the ultra-high molecular weight polyethylene fiber bundling device to be widely used for bundling of various sizes and quantities of jelly yarns 7, the wire splitting fork 4 in the utility model is detachably connected to the wire splitting rod 3. Moreover, the position of the wire splitting fork 4 on the wire splitting rod 3 is not completely fixed, and can be moved on the wire splitting rod 3 according to actual needs. Specifically, when the size or quantity of the jelly yarn 7 changes, the distance between the wire splitting forks 4 can be adjusted by disassembly, or the number of wire splitting forks 4 set on the wire splitting rod 3 can be increased or decreased by disassembly, so as to better bundle the jelly yarn 7.

[0041] like Figure 2 As shown, the wire splitting fork 4 of the utility model includes an annular body 41 and a stop rod 42. The annular body 41 and the stop rod 42 are detachably connected.

[0043] In order to make it easier for the jelly thread 7 to cross through the first support rod and the second support rod, the height of the first support rod needs to be lower than that of the second support rod. In addition, the height of the splitter rod 3 is higher than that of the first support rod, the height of the second support rod is higher than that of the splitter rod 3, and the height of the second support rod is approximately at half the height of the blocking rod 42, so that the contact between the jelly thread and the splitter rod can be reduced.
