Technical Field

[0001] The utility model belongs to the technical field of fiber processing, and in particular relates to a curling structure of a durable water-repellent composite short fiber. Background Art

[0002] The crimping machine is a key equipment in the post-processing production line of chemical fiber staple fibers; it refers to the equipment that curls and deforms the chemical fiber staple fiber bundles in processing according to the principle of mechanical crimping. Most of the current crimping machines are stuffing box type, which are divided into horizontal and vertical types. Before the crimping machine, it is often necessary to use steam or electric heating plates to increase the temperature of the crimped fibers in advance to enhance the crimping effect. A wire adjustment rack is generally set in front of the crimping machine to arrange the thickness of the yarn bundle to be uniform. There is also a swinging wire mechanism or a wire outlet bucket after the crimping machine. In the actual processing process, in order to meet the oil content of the water-repellent fiber, the fiber also needs to be sprayed with oil, but the amount of oil sprayed cannot be adjusted in real time, resulting in oil waste.

[0003] In order to solve the deficiencies of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a fiber surface oil spraying mechanism [202311801201.7], which includes a guide member extending from the discharge end of the crimping machine to the conveying mechanism, including a first guide seat, a second guide seat and an operating box, and the operating box has an operating port connected to the box body at opposite ends, so that the fiber bundle can move from the first guide seat to the second guide seat through the operating box; a support member, which is distributed in the operating box along the distribution direction between the first guide seat and the second guide seat; an oil spraying member, which is installed on opposite sides of the operating box and extends into the operating box; and a driving assembly, which cooperates with the support member to drive the support member to move toward the first guide seat until they abut one by one, or drive the support member to move away from the first guide seat until they are separated from each other.

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-4 As shown, a curling structure of a durable water-repellent composite staple fiber includes a curling frame 1 connected to a transmission structure, a pair of parallel curling guide rollers 2 are rotatably mounted on the curling frame 1, and the fiber transmission and winding are guided by the curling guide rollers 2. Before the fiber is drawn, the fiber is usually heated to activate the movement of the molecular chain in the fiber, so that the fiber is easier to be pulled under the action of external force. An oil spraying assembly 3 is installed between the curling guide rollers 2 to increase the oil content of the water-repellent fiber. An oil return assembly 4 opposite to the oil spraying assembly 3 is installed on the curling frame 1 to recover and process excess oil. The curling guide roller 2 is equipped with an oil scraping assembly 5 to ensure uniform distribution of oil on the fiber surface. The oil spraying assembly 3 is equipped with a stop assembly 6 connected to the oil return assembly 4. When the amount of oil in the oil return assembly 4 exceeds the set threshold, the stop assembly 6 adjusts the oil intake of the oil spraying assembly 3 in time.

[0024] Specifically, the curling frame 1 is a frame structure as a whole, and specifically includes a pair of parallel and triangular support plates 11, a support rod 12 is connected between the support plates 11, and the curling guide roller 2 is rotatably installed between the support plates 11 and maintained parallel to the support rod 12. In order to improve the flexibility of the position adjustment of the curling frame 1, the support plate 11 is hinged with an adjustment seat 13, and an adjustment component is provided between the adjustment seat 13 and the support plate 11.

[0025] Specifically, the adjustment assembly includes an adjustment rod 14 rotatably connected to the adjustment seat 13, the other end of the adjustment rod 14 is slidably connected to an adjustment slot 15 provided on the support plate 11, and a hydraulic push rod 16 is installed on the adjustment seat 13, and the telescopic end of the hydraulic push rod 16 is rotatably connected to the adjustment rod 14. The hydraulic push rod 16 applies a rotational torque to the adjustment rod 14, and the end of the adjustment rod 14 slides relative to the adjustment slot 15, and the support plate 11 swings relative to the adjustment seat 13 as a whole.

[0026] Furthermore, similar to the existing guide roller structure, the curling guide roller 2 in the present application includes a roller shaft 21 rotatably connected to the curling frame 1, and the outer side of the roller shaft 21 is covered with a roller sleeve 22. The roller sleeve 22 is usually made of elastic material to ensure the bonding effect with the fiber.

[0027] Furthermore, the oil injection assembly 3 includes an oil injection pipe 31 installed between the curling guide rollers 2 and parallel to the curling guide rollers 2. The oil injection pipe 31 is connected to an external liquid pump to provide high-pressure oil. The oil injection pipe 31 is axially arranged with atomizing nozzles 32 so that the oil is evenly distributed on the fiber surface in a mist form. The curling frame 1 is provided with an isolation cover 33 located above the oil injection pipe 31 to prevent the oil mist from dispersing.

[0028] In addition, in order to limit the amount of residual oil, an oil scraping assembly 5 is introduced to scrape off excess oil on the fiber surface, specifically comprising a scraper 51 arranged adjacent to the curling guide roller 2, and an oil-repellent groove 52 extending toward the end of the scraper 51 is formed on the surface of the scraper 51. The scraper 51 is usually fixed with a screw, and the relative distance between the blade and the curling guide roller 2 can be adjusted.

[0029] At the same time, the oil return assembly 4 is used to improve the oil recovery rate, which includes an oil return groove 41 connected to the winding frame 1. The oil return groove 41 is located below the winding guide roller 2 to receive the oil. The oil return groove 41 is connected to the oil return pipe 42, and the oil return pipe 42 transmits the oil to the filtering mechanism and other structures.

[0030] It can be seen that the stop assembly 6 includes a vertical rod 61 fixed at the bottom of the oil return groove 41, a liquid level sensor 62 is installed on the vertical rod 61, the liquid level sensor 62 is connected to the main control module, the main control module is connected to the flow valve 63, and the flow valve 63 is connected to the oil injection assembly 3. When the liquid level sensor 62 detects that the oil volume in the oil return groove 41 exceeds the threshold, the flow valve 63 reduces the oil volume or stops in time.

[0031] Obviously, the crimping frame 1 has several guide plates 7 built therein, with gaps between the guide plates 7. The guide plates 7 mainly cooperate with the crimping guide rollers 2 to limit the fiber orientation, and are isolated from the guide plates 7 during the fiber conduction process. Corresponding sensor elements can be fixed on the guide plates 7.

[0032] Preferably, the guide plates 7 are provided with air jets 71, which are provided with air jets 72 opposite to the gaps between the guide plates 7. The air jets 72 spray high-pressure air to comb the fiber surface and remove impurities on the surface.

[0033] To sum up, the principle of this embodiment is that the curling frame 1 has a built-in curling guide roller 2 to guide the fiber transmission curling, the oil injection assembly 3 sprays oil evenly toward the fiber surface, the excess oil is scraped off by the oil scraping assembly 5 and input into the oil return assembly 4, and when the oil return assembly 4 exceeds a predetermined threshold, the stop assembly 6 adjusts the oil intake of the oil injection assembly 3.
