Description

A device and method for forming a high-uniformity web of down fibers Technical Field

[0001] This invention relates to the field of textile materials and technology, specifically to a device and method for forming a web with high uniformity of down fibers. Background Technology

[0002] Down, as a natural and highly efficient insulating material, has excellent loft, lightweight and heat insulation properties due to its unique spatial branching structure, and is widely used in clothing, bedding and other fields; the "down cluster" structure in down aggregates can effectively store still air and form a good thermal resistance layer.

[0003] However, traditional down filling processes are prone to uneven distribution, clumping, and voids. To address this issue, the invention patent CN113636520B (authorized publication number) proposes an apparatus and method for preparing a uniformly distributed down fiber web. This invention consists of a dispersing mechanism, a down storage mechanism, a web-laying mechanism, and a fixing mechanism. The fiber web is formed by dispersing the fed down clumps through a dispersing roller, then allowing the loose down to enter the down storage mechanism. Under the control of the down-output rollers in the web-laying mechanism, the falling down is output row by row, achieving a uniform web with a thickness of 1 to 6 down clusters.

[0004] However, the aforementioned invention patent still has some inherent and insurmountable limitations, specifically in the following aspects: First, in the air medium, the falling and distribution of down is easily affected by the mechanical vibration of the equipment itself, random airflow disturbances in the workshop, and electrostatic adsorption between down fibers. These factors combined can easily lead to localized accumulation or thinning of fibers after web laying, creating a bottleneck in further improving the uniformity of the finished product; Second, in the down web laying process of the aforementioned invention, dry processing easily generates down dust and fiber scattering, which not only affects the workshop working environment but may also cause raw material loss.

[0005] Therefore, this invention proposes a device and method for forming a high-uniformity web of down fibers, aiming to overcome the limitations of the above-mentioned inventions. Summary of the Invention

[0006] To solve the above problems, the present invention proposes the following technical solution: a down fiber high uniformity web-forming device, comprising a frame, a down dispersion and storage mechanism, a web-forming mechanism, and a conveying mechanism; the down dispersion and storage mechanism is fixedly installed on the frame, the web-forming mechanism is fixedly installed on the frame and below the down dispersion and storage mechanism, and the conveying mechanism is fixedly installed on the frame and at the left end of the web-forming mechanism; the down dispersion and storage mechanism includes a down storage box with a U-shaped cross-section and an opening at the lower end of the down storage box; several longitudinal dispersing rollers are rotatably installed on the down storage box, and several transverse dispersing rollers are rotatably installed on the down storage box and below the longitudinal dispersing rollers, the longitudinal dispersing rollers and the transverse dispersing rollers being arranged perpendicular to each other; the web-forming mechanism includes a down dispersion and storage mechanism fixedly installed on the frame and below the down storage box.

A No. 2 water tank is fixedly connected to the lower side of the left end of the No. 1 water tank. A water supply pipe is fixedly installed on the right side of the No. 2 water tank, and a water pump is installed on the water supply pipe. The other end of the water supply pipe is installed on the right side of the No. 1 water tank. The conveying mechanism includes a cloth-holding roller rotatably mounted on the frame. A net-receiving roller is rotatably connected on the frame and above the cloth-holding roller. A pressure roller is slidably connected on the frame and above the net-receiving roller. The pressure roller slides in the up-down direction. A reversing roller is rotatably connected on the frame and at the lower right end of the No. 1 water tank. The reversing roller is located to the right of the cloth-holding roller. A conveying net curtain is wound on the cloth-holding roller. The other end of the conveying net curtain passes around the reversing roller and is wound onto the net-receiving roller.

[0007] Preferably, the conveying curtain between the reversing roller and the taking-up roller is located on the lower side of the left end of the No. 1 water tank. When the water in the No. 1 water tank flows downward, the down fibers on the water surface are carried by the water flow and evenly spread onto the conveying curtain.

[0008] Preferably, two baffles arranged in a mirror image are rotatably installed on the front and rear sides of the No. 1 water tank. The angle between the baffles and their corresponding sides and the height of the baffles themselves can be manually adjusted as needed. The highest point of the baffle is higher than the highest point of the left slope of the No. 1 water tank. A baffle is slidably installed on the upper side of the No. 1 water tank. The baffle slides in the up-down direction. The lowest point of the baffle is higher than the highest point of the left slope of the No. 1 water tank.

[0009] Preferably, the water supply pipe is divided into at least three channels evenly distributed front to back at one end of the right side of the No. 1 water tank, and each channel is equipped with a switch to control the water flow rate within the channel.

[0010] Preferably, the pressing roller slides in the up-down direction, and the circumferential surface of the pressing roller is always in contact with the conveying curtain outside the taking-up roller.

[0011] Preferably, a number of beaters are evenly distributed on the circumference of the longitudinal and transverse dispersing rollers, and the beaters on two adjacent longitudinal dispersing rollers are staggered in the horizontal direction, and the beaters on two adjacent transverse dispersing rollers are also staggered in the horizontal direction; all beaters are slender rods with rounded ends; the inner surface of the down storage box is a smooth surface that has been smoothed and is anti-static.

[0012] Preferably, each of the longitudinal dispersing rollers and the transverse dispersing rollers is connected to a servo motor; the take-up roller is connected to a servo motor, and the servo motor drives the take-up roller to rotate.

[0013] Preferably, a drying device is fixedly installed on the frame and on the upper side of the conveyor curtain located between the reversing roller and the take-up roller.

[0014] Preferably, a viewing window made of transparent material is installed on the front surface of the down storage box; a photoelectric sensor is fixedly installed on the front side of the viewing window.

[0015] In addition, the present invention also provides a method for forming a highly uniform web of down fibers, comprising the following steps:

[0016] S1. Preparation: First, fill water tanks 1 and 2 with water. Then, start the water pump on the water supply pipe. The water pump will start to pump water from water tank 2 into water tank 1. At the same time, the water in water tank 1 will start to flow to the left at a constant speed. Then, adjust the angle between the baffle and its corresponding side and adjust the height of the baffle as needed.

[0017] S2. Feeding and dispersing fibers: The down clumps are fed into the top of the down storage box and the servo motors corresponding to the longitudinal and transverse dispersing rollers are started at the same time. Driven by the servo motors, the longitudinal and transverse dispersing rollers start to rotate at the set speed and direction. The beaters on the dispersing rollers completely disperse the down into individual down clusters. The individual down clusters fall onto the water surface in the No. 1 water tank, and the water falls directly into the No. 2 water tank to start the next cycle.

[0018] S3. Laying down and rolling it up: The down fibers on the water surface are carried by the water flow to be evenly laid on the conveyor curtain. At the same time, the servo motor corresponding to the take-up roller drives the take-up roller to rotate. The drying device dries the down on the conveyor curtain. Finally, the rotating take-up roller pulls the conveyor curtain on the cloth roller and re-rolls it up. At this time, a uniform single layer of down is laid on one side of the conveyor curtain.

[0019] The beneficial effects of this invention are as follows:

[0020] I. This invention uses directional water flow to carry down feathers, allowing them to float and spread on the water surface. The system uses adjustable-angle baffles to constrain the distribution range of the down feathers and adjustable-height baffles to control the thickness of the down layer on the water surface. By using water flow as the web-laying medium, and taking advantage of the inherent fluid stability and extensibility of water flow, the fiber distribution disturbances caused by mechanical vibration, air turbulence, and electrostatic adsorption in dry web-laying are fundamentally eliminated. The down feathers float naturally on the water surface and spread out with the flow, which greatly improves the uniformity and effectively solves the process problems such as local accumulation or local thinning, so that the uniformity of the web-forming reaches a new level.

[0021] Second, this invention achieves a gradual and flexible opening of down clumps by designing a multi-roller dispersing mechanism with horizontal and vertical vertical distribution, double-layer arrangement, and staggered beaters, and by using slender rod-shaped beaters with rounded ends. The rotation speed and direction of each dispersing roller can be independently and steplessly adjusted, which can beat and comb the down in a multi-dimensional and low-impact manner during the falling process, ensuring that the down comforter is fully decomposed into individual down clusters, while preserving the complete structure and fluffiness of the down clusters to the maximum extent, laying an ideal fiber raw material foundation for subsequent high uniformity web laying.

[0022] Third, the present invention adopts a wet process, which eliminates the scattering of down dust and fibers, improves the workshop working environment, meets the requirements of green and clean production, and also reduces the loss of raw materials. Attached Figure Description

[0028] The embodiments of the present invention are described in detail below.

[0029] Referring to Figures 1-3, a device for forming a highly uniform web of down fibers includes a frame 1, a down-dispersing and storing mechanism 2, a web-forming mechanism 3, and a conveying mechanism 4. The down-dispersing and storing mechanism 2 is fixedly installed on the frame 1. The web-forming mechanism 3 is fixedly installed on the frame 1 below the down-dispersing and storing mechanism 2, and the conveying mechanism 4 is fixedly installed on the frame 1 at the left end of the web-forming mechanism 3. The down-dispersing and storing mechanism 2 includes a down-storage box 21 with a U-shaped cross-section and an opening at its lower end. Several longitudinal dispersing rollers 22 are rotatably mounted on the down-storage box 21, and several transverse dispersing rollers 23 are rotatably mounted on the down-storage box 21 below the longitudinal dispersing rollers 22. The longitudinal and transverse dispersing rollers 22 are arranged perpendicularly to each other. The web-forming mechanism 3 includes a first water tank 31 fixedly installed on the frame 1 below the down-storage box 21. 1. The left end is an inclined plane, and the highest point of the inclined plane is lower than the other three sides of the first water tank 31. The lower side of the left end of the first water tank 31 is fixedly connected to the second water tank 32. The right side of the second water tank 32 is fixedly installed with a water supply pipe 321. A water pump is installed on the water supply pipe 321. The other end of the water supply pipe 321 is installed on the right side of the first water tank 31. The conveying mechanism 4 includes a cloth holding roller 42 rotatably mounted on the frame 1. A net taking roller 44 is rotatably connected on the frame 1 and above the cloth holding roller 42. A pressure roller 45 is slidably connected on the frame 1 and above the net taking roller 44. The pressure roller 45 slides in the up and down direction. A reversing roller 43 is rotatably connected on the frame 1 and at the lower right end of the first water tank 31. The reversing roller 43 is located to the right of the cloth holding roller 42. A conveying net curtain 41 is wound on the cloth holding roller 42. The other end of the conveying net curtain 41 passes around the reversing roller 43 and is wound onto the net taking roller 44.

[0030] This invention utilizes directional water flow to carry down feathers, allowing them to float and spread on the water surface. Due to the water-repellent properties of down feathers, they can naturally float and spread on the water surface, forming a single-layer or multi-layer suspended distribution. The water flow itself has good fluid stability and extensibility, which can effectively carry and transfer down fibers. Moreover, its horizontal flow process can naturally eliminate the uneven distribution problems caused by airflow disturbance, electrostatic adsorption, or mechanical vibration in dry web laying. The presence of water flow is gentle and uniform, providing a controllable and non-impact "floating platform" for down feathers, essentially avoiding fiber damage and secondary entanglement, and creating a more ideal environment for achieving "high uniformity and low damage" web formation.

[0031] Referring to Figures 1-3, the conveying curtain 41 between the reversing roller 43 and the taking-up roller 44 is located on the lower left side of the first water tank 31. When the water in the first water tank 31 flows downward, the down fibers on the water surface are carried by the water flow and evenly spread onto the conveying curtain 41. Two baffles 311 arranged in a mirror image are rotatably installed on the front and rear sides of the first water tank 31. The angle between the baffles 311 and their corresponding sides and the height of the baffles 311 themselves can be manually adjusted as needed. The highest point of the baffles 311 is higher than the highest point of the left slope of the first water tank 31. A baffle 312 is slidably installed on the upper side of the first water tank 31. The sliding direction of the baffle 312 is up and down. The lowest point of the baffle 312 is higher than the highest point of the left slope of the first water tank 31.

[0032] This invention uses directional water flow to carry down feathers and make them float and spread on the water surface. It uses adjustable-angle baffles 311 to constrain the distribution range of down feathers and uses adjustable-height baffles 312 to control the thickness of the down layer on the water surface.

[0033] Referring to Figures 3 and 4, the water supply pipe 321 is located at the right end of the first water tank 31 and is divided into at least three channels evenly distributed front and back. Each channel is equipped with a switch to control the water flow rate within the channel. Several beaters 221 are evenly distributed on the circumference of the longitudinal dispersing roller 22 and the transverse dispersing roller 23. The beaters 221 on two adjacent longitudinal dispersing rollers 22 are staggered in the horizontal direction, and the beaters 221 on two adjacent transverse dispersing rollers 23 are also staggered in the horizontal direction. All beaters 221 are slender rods with rounded ends. The inner surface of the lint storage box 21 is a smooth surface that has been smoothed and is anti-static. Each of the longitudinal dispersing rollers 22 and the transverse dispersing rollers 23 is connected to a servo motor.

[0034] This invention utilizes a multi-roller dispersing mechanism with horizontal and vertically distributed, double-layered, and staggered beaters 221. The use of slender, rod-shaped beaters 221 with rounded ends enables a gradual and flexible opening of down clusters. The rotation speed and direction of each dispersing roller are independently and steplessly adjustable, allowing for multi-dimensional, low-impact beating and combing of the down during its descent. This ensures the down is fully broken down into individual, separate down clusters, while maximizing the preservation of the complete structure and fluffiness of the down clusters, laying an ideal foundation for high-uniformity web formation.

[0035] Referring to Figure 4, a viewing window 211 is installed on the front surface of the velvet storage box 21. The viewing window 211 is made of transparent material. A photoelectric sensor 212 is fixedly installed on the front side of the viewing window 211.

[0036] This invention uses a photoelectric sensor 212 to monitor the down accumulation state in the down storage box 21 in real time and links it with the feeding system to form an automatic control closed loop, thereby accurately adjusting the down supply and ensuring continuous, stable and controllable feeding. This fundamentally avoids the problem of uneven web formation caused by insufficient material or excessive accumulation, and is a key prerequisite for achieving highly uniform web formation.

[0037] Referring to Figures 2 and 3, the pressing roller 45 slides in the up-down direction, and the circumferential surface of the pressing roller 45 is always in contact with the conveying curtain 41 outside the taking-up roller 44; the taking-up roller 44 is connected to a servo motor, which drives the taking-up roller 44 to rotate; a drying device 46 is fixedly installed on the frame 1 and on the upper side of the conveying curtain 41 located between the reversing roller 43 and the taking-up roller 44.

[0038] The pressure roller 45 is used to press the down feathers and the conveyor curtain 41 together to prevent the down feathers from becoming too loose during the winding process.

[0039] This invention uses directional water flow to carry down feathers and allow them to float and spread on the water surface. The system uses adjustable-angle baffles 311 to constrain the distribution range of the down feathers and uses adjustable-height baffles 312 to control the thickness of the down layer on the water surface. This hydrodynamic web-forming mechanism is gentle and controllable, and can effectively eliminate problems such as local thickness unevenness caused by airflow disturbance or uneven gravity distribution in dry web laying. It can stably prepare down fiber webs with uniform and controllable thickness from quasi-single layer to multi-layer, achieving a significant improvement in web laying uniformity.

[0040] In addition, the present invention also provides a method for preparing a highly uniform web of down fibers, comprising the following steps:

[0041] S1. Preparation: First, fill water tank 31 and water tank 32 with water. Then, start the water pump on the water supply pipe 321. The water pump will start to pump water from water tank 32 into water tank 31. At the same time, the water in water tank 31 will start to flow to the left at a constant speed. Then, adjust the angle between the baffle 311 and its corresponding side and adjust the height of the baffle 312 as needed.

[0042] S2. Feeding and dispersing fibers: The down clumps are fed into the down storage box 21 from the top and the servo motors corresponding to the longitudinal dispersing roller 22 and the transverse dispersing roller 23 are started at the same time. Driven by the servo motors, the longitudinal dispersing roller 22 and the transverse dispersing roller 23 start to rotate at the set speed and direction. The beaters 221 on the longitudinal dispersing roller 22 and the transverse dispersing roller 23 completely disperse the down into individual down clusters. The individual down clusters fall onto the water surface in the first water tank 31, and the water falls directly into the second water tank 32 to start the next cycle.

[0043] S3. Laying down and rolling it up: The down fibers on the water surface are carried by the water flow to be evenly laid on the conveying curtain 41. At the same time, the servo motor corresponding to the take-up roller 44 drives the take-up roller 44 to rotate. The drying device 46 dries the down on the conveying curtain 41. Finally, the rotating take-up roller 44 pulls the conveying curtain 41 on the cloth holding roller 42 and re-rolls it up. At this time, a uniform single layer of down is laid on one side of the conveying curtain 41.

[0044] The following is an embodiment of the present invention:

[0045] To create a 2cm thick, highly uniformly distributed down fiber web: Goose down clumps are fed into the down storage box 21 from the top. Simultaneously, the servo motors corresponding to the longitudinal dispersing roller 22 and the transverse dispersing roller 23 are activated. The speed of the longitudinal dispersing roller 22 is controlled at 110 rpm, and the speed of the transverse dispersing roller 23 is controlled at 140 rpm. Under the action of the longitudinal and transverse dispersing rollers 22 and 23, the down is dispersed and falls onto the water surface in the first water tank 31. The water flow rate is controlled by adjusting the switch on the water supply pipe 321 to a flow rate of 100 m / min. The distribution range of the down is constrained by the adjustable baffle 311, and the height of the baffle 312 above the water surface is adjusted to control the thickness of the down layer, thus creating a 2cm thick, highly uniformly distributed down fiber web. The down is then dried by the drying device 46 on the conveying mechanism 4, and finally wound up by the take-up roller 44.

[0046] Example 2:

[0047] To create a quasi-single-layer duck down uniformly distributed fiber web: duck down is fed into the down storage box 21 from the top, and the servo motors corresponding to the longitudinal dispersing roller 22 and the transverse dispersing roller 23 are started simultaneously. The speed of the longitudinal dispersing roller 22 is controlled at 50 rpm, and the speed of the transverse dispersing roller 23 is controlled at 80 rpm. Under the action of the longitudinal dispersing roller 22 and the transverse dispersing roller 23, the duck down is dispersed and falls into the water surface in the first water tank 31. The switch on the water supply pipe 321 is adjusted to control the water flow rate of the water supply pipe 321, so that the water flow velocity is 60 m / min. The distribution range of the duck down is constrained by the adjustable angle baffle 311, and the height of the baffle 312 from the water surface is adjusted to control the thickness of the duck down layer, thus preparing a quasi-single-layer duck down highly uniformly distributed fiber web. After the moisture is removed by the drying device 46 on the conveying mechanism 4, the web is wound up by the take-up roller 44.

[0048] Example 3:

[0049] Preparation for sorting down of different colors: Goose down is fed into the down storage box 21 from the top, and the servo motors corresponding to the longitudinal dispersing roller 22 and the transverse dispersing roller 23 are started at the same time. The speed of the longitudinal dispersing roller 22 is controlled at 80 rpm, and the speed of the transverse dispersing roller 23 is controlled at 110 rpm. Under the action of the longitudinal dispersing roller 22 and the transverse dispersing roller 23, the goose down is dispersed and falls into the water surface in the first water tank 31. The switch on the water supply pipe 321 is adjusted to control the water flow rate of the water supply pipe 321, so that the water flow velocity is 100 m / min. The distribution range of duck down is constrained by the adjustable angle baffle 311. At the same time, the height of the baffle 312 from the water surface is adjusted to control the thickness of the duck down layer, so as to prepare a goose down highly uniformly distributed fiber web with a natural thickness of 5 cm. The moisture is removed by the drying device 46 on the conveying mechanism 4, and the net taking roller 44 takes the net into a roll to facilitate the subsequent grabbing mechanism to grab the down of different colors.

[0050] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered within the protection scope of the present invention.

The water pump starts to pump water from water tank 2 (32) into water tank 1 (31). At the same time, the water in water tank 1 (31) starts to flow to the left at a uniform speed. Then, adjust the angle between the baffle (311) and its corresponding side and adjust the height of the baffle (312) as needed. S2. Feeding and dispersing fibers: Feed the down clumps from the top of the down storage box (21) and start the servo motors corresponding to the longitudinal dispersing roller (22) and the transverse dispersing roller (23). Driven by the servo motors, the longitudinal dispersing roller (22) and the transverse dispersing roller (23) move at the set speed and direction. The rotation begins, and the beaters (221) on the longitudinal dispersing roller (22) and the transverse dispersing roller (23) completely disperse the down into single down clusters. The single down clusters fall onto the water surface in the first water tank (31), and the water falls directly into the second water tank (32) to start the next cycle. S3, Spread the down and roll it up: The down fibers on the water surface are evenly spread onto the conveyor curtain (41) by the water flow. At the same time, the servo motor corresponding to the take-up roller (44) drives the take-up roller (44) to rotate. The drying device (46) dries the down on the conveyor curtain (41). Finally, the rotating take-up roller (44) pulls the conveyor curtain (41) on the cloth holding roller (42) and rolls it up again. At this time, a uniform single layer of down is spread on one side of the conveyor curtain (41).
