Description

Technical Field

[0001] The present application belongs to the technical field of fiber ropes, and in particular relates to a device for raising the intermittent strands of a monofilament twisted wire. Background Art

[0002] Ropes are widely used in marine operations, and are currently mainly used in lifting, traction, fencing and other work sites. In some special working environments, such as marine aquaculture, ropes are needed to provide adsorption and reproduction sites for eggs, algae or other microorganisms, but ordinary ropes are smooth and have densely arranged fibers, which cannot meet the above requirements.

[0003] To this end, a certain number of free fiber segments can be set on the surface of ordinary ropes to form fiber hairs that are free from the rope body, thereby solving the problems existing in the prior art. Ropes with fiber hairs on the rope body can usually be called raised ropes. Raised ropes are ropes with a relatively special structure, and different usage environments have requirements for the length and quantity of the raised hairs. The conventional production method for this type of rope is to install a blade to break the wire during rope making, but due to the influence of the fixed position, sharpness and wire breaking process of the blade, the length and number of broken wires are uncontrollable. At the same time, it is easy to cut too deep during rope making, which will damage the rope body and affect its breaking force and other properties, affecting the actual use effect and service life of this type of rope.

[0041] In order to better illustrate the content of the present application, numerous specific details are provided in the specific examples below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In the embodiments, some methods, means, instruments, equipment, etc. well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0042] Under the premise of no conflict, the technical features disclosed in the embodiments of the present application can be combined arbitrarily, and the resulting technical solutions belong to the contents disclosed in the embodiments of the present application.

[0043] In some embodiments, a monofilament twisted yarn interval breaking and fluffing device comprises: a filament dividing assembly, on which a plurality of sieve holes are provided, and the fiber monofilaments used to form the monofilament twisted yarn pass through the plurality of sieve holes respectively to be arranged in filament division; a filament breaking assembly, inside of which a first through cavity with an axially symmetrical structure for passing the monofilament twisted yarn is provided, and at least one cutter for cutting the fiber monofilaments is arranged at intervals on the inner wall of the first through cavity; wherein the filament breaking assembly is arranged at the downstream end of the filament dividing assembly, and the symmetry axis of the first through cavity is coaxially arranged with the center of the filament dividing assembly; the fiber monofilaments are arranged to enter the first through cavity after being arranged in filament divisions in the sieve holes, and are twisted during the movement to generate a spiral motion to form a monofilament twisted yarn, and the spirally moving monofilament twisted yarn contacts the cutter, and part of the fiber monofilaments on the surface of the monofilament twisted yarn are cut off at intervals by the cutter to form fiber fluff.

[0044] The monofilament twisted yarn interval interruption and fluffing device is usually used for continuous processing of the monofilament twisted yarn. During the processing, the monofilament twisted yarn continuously passes through the fluffing device, and the fiber monofilaments on the surface of the monofilament twisted yarn are intermittently cut off to form fiber hairs that are spaced and evenly distributed on the surface of the monofilament twisted yarn along its axial direction and on its outer surface. When the multiple fiber monofilaments forming the monofilament twisted yarn pass through the wire splitting assembly, they pass through the sieve holes set on the wire splitting assembly respectively. After passing through the sieve holes, the fiber monofilaments are pre-arranged in layers and groups to form an orderly arranged fiber monofilament bundle. After passing through the wire splitting assembly, they are continuously twisted to form a monofilament twisted yarn with uniform twist and regular fiber monofilament arrangement. The monofilament twisted yarn is continuously twisted to form a spiral motion trajectory during the process of passing through the wire breaking assembly. The monofilament twisted yarn contacts the cutter in the wire breaking assembly during the spiral advance, and the fiber monofilaments on the surface of the monofilament twisted yarn are cut off by it to form a free end of the fiber monofilament. The free end of the fiber monofilament extends out from the monofilament twisted yarn body to form fiber hair; because the cutter is arranged in the first through cavity in the wire breaking assembly at intervals, only the partial surface fiber monofilaments on the monofilament twisted yarn are cut off, and the cutting action is performed at intervals, continuously and periodically, so continuous and uniformly distributed fiber hair is formed on the surface of the moving monofilament twisted yarn. Usually, the direction of the cutter is perpendicular to the forward direction of the monofilament twisted yarn, so as to effectively cut the fiber monofilaments. Usually at least one cutter is provided. When one cutter is provided, the cutter is only provided on a part of the circumference of the inner wall of the first through cavity. The fiber monofilaments on its surface are cut once when the monofilament twisted wire moves spirally once. When multiple cutters are provided, the multiple cutters are arranged at intervals along the circumference of the inner wall of the first through cavity. The fiber monofilaments on its surface are cut multiple times when the monofilament twisted wire moves spirally once. The multiple cutting positions are distributed on the outer circumference of the monofilament twisted wire consistent with its spiral motion trajectory. Multiple monofilament fibers at the cutting position are cut off to form twice the number of fiber hairs.

Usually, under the combing action of the combing hairs, the free ends of the fiber hairs extending out from the surface of the monofilament twisted yarn extend toward the rear of the monofilament twisted yarn, and the fiber hairs are arranged more regularly, and the exposure effect is better.

[0046] As an optional embodiment, the combing assembly includes a support disk, a hair comber detachably connected to the support disk is provided in the support disk, a second through cavity is provided in the hair comber, and a combing hair is provided inside the second through cavity, and the combing hair is evenly distributed on the inner wall, and the broken silk twisted line passing through the second through cavity is combed, and the broken fiber monofilaments are arranged, and the broken fiber monofilaments are completely exposed to form fiber hair distributed on the monofilament twisted line.

For example, in an inverted truncated cone-shaped cavity, the diameter of the entrance end at the top is large, and the diameter of the exit end at the bottom is small. Usually, the inner diameter of the entrance end refers to the inner diameter of the cavity between the combed hairs at the entrance end, and the inner diameter of the exit end refers to the inner diameter of the cavity between the combed hairs at the outlet end.

Usually, in order to facilitate the arrangement of the fiber monofilaments in the sieve holes, an opening can be arranged on one side of the sieve holes, and the opening is usually arranged on the narrow side of the rectangular opening; for this purpose, a wire-blocking plate can be arranged to seal the opening of the sieve hole, so as to confine the fiber monofilaments in the sieve holes, and at the same time, the wire-blocking plate and the wire-dividing screen need to be movably connected, so as to facilitate opening or closing the wire-blocking plate.

[0089] The monofilament twisted yarn broken yarn raising device disclosed in Example 8 is used to produce 16 mm polyolefin raised monofilament twisted yarn, wherein the fiber monofilament is a polyolefin monofilament with a specification of 40 and 720D, the fiber hair length is not less than 4 cm, and the broken yarn interval is not greater than 0.3 m. The production method comprises:

[0090] (1) According to the fiber monofilament twisting specifications, the number of sieve holes in the square wire-dividing assembly is determined to be 20, the sieve hole width is 1 mm, a 2.5 cm wide wire blocking plate is selected, and the assembled wire-dividing assembly is fixedly connected to the support frame;

[0091] (2) Select a cylindrical wire-breaking component, select a four-tooth sawtooth tool, set two layers of openings on the cylindrical wire-breaking component, use four tools for each layer of openings, arrange them at equal intervals, and cross the tools of the upper and lower layers. Place the assembled wire-breaking component directly below the wire-dividing component and fix it to the support frame;

[0092] (3) Select a suitable combing device and fix it on a cylindrical support plate to form a combing assembly, and then fix the combing assembly on a support frame, with its central axis coaxially arranged with the central axis of the wire breaking assembly; the inner diameter of the inlet end of the combing device is controlled to about 3 mm using a combing brush, and the inner diameter of the outlet end is controlled to about 2.3 mm using a combing brush.

[0093] (4) The assembled interval breaking and fluffing device is installed just above the spindle of the twisting machine, and then the fiber filament bundle is passed through the filament separation component, the breaking component and the combing component in sequence, and the twisting machine is started. The fiber filament bundle passes through the cavity in the device, and rotates and moves downward continuously at the same time. During the rotation and downward movement, the fiber filaments contact the cutter and are cut at intervals to form fiber hairs. During the continuous twisting process, the fiber filaments are twisted into interval breaking and fluffing monofilament twisted yarns.

[0094] The monofilament twisted wire interval breaking and raising device disclosed in the embodiment of the present application can be used to make breaking and raising ropes. The monofilament twisting interval broken thread raising device uses a wire dividing component to pre-arrange the monofilament bundles in layers in advance, so as to ensure that they can be arranged closely and have uniform twist during twisting, thereby ensuring the uniformity of broken threads; according to the twisting principle of rope twisting, the interval broken thread component is used to make fiber monofilaments of different materials and different composite numbers twist and rotate to form monofilament twisted threads and move, and the intervally arranged cutters are used to cut off some fiber monofilaments on the monofilament twisted threads, so as to achieve the technical effect of forming fiber hair by interval broken threads, and the length, shape and number of the cutters can be adjusted, and the length and number of the broken fiber monofilaments can be further controlled by coordinating the twisting twist and the wire feeding speed; the broken fiber monofilaments are combed by the combing component, and the broken fiber fibers are combed unidirectionally by combing during the movement of the monofilament twisted threads, so as to prevent the broken threads from being twisted into the monofilament twisted thread body during the twisting process, thereby affecting the broken thread raising effect; the components cooperate with each other, which can not only ensure the uniformity of the monofilament twist and the broken thread raising, but also ensure that the broken threads can be fully exposed. The single-filament twisted line interval breaking and raising device can greatly improve the breaking and raising efficiency and quality, improve the twist stability of the twisted line, ensure the appearance uniformity and strength stability of the breaking and raising rope, greatly reduce the generation of defective products and improve production efficiency.
