Description

Technical Field

[0001] This invention belongs to the field of down processing technology, specifically a surface modification device for heat-retaining down fibers. Background Technology

[0002] Heat-retaining down fiber is a new type of down fiber material with special heat-retaining properties. It is mainly achieved by adding or compounding heat-retaining materials to the surface of the down fiber, giving it better heat storage and temperature regulation performance. These heat-retaining materials can absorb heat at higher temperatures and release heat at lower temperatures, thereby extending the warmth retention time of the down fiber. Due to its excellent warmth retention and environmentally friendly characteristics, heat-retaining down fiber is widely used in outdoor thermal clothing, sleeping bags, directional heat storage devices, and other products. With increasing environmental awareness and continuous technological development, the application scope of heat-retaining down fiber will further expand.

[0003] Equipment for surface modification of heat-storing down fibers is typically designed to alter the surface properties of down fibers through physical, chemical, or biological methods, thereby endowing them with new or improved properties. Existing down modification equipment suffers from low integration and a lack of effective coordination between its various components, impacting overall performance and efficiency. Furthermore, during the modification process, the down exhibits poor dispersion, making it difficult to achieve sufficient contact with the down during drying and liquid treatment, resulting in suboptimal heat-storing layer performance and surface quality.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1 To address the issues of low integration and lack of effective coordination between different parts in existing down modification equipment, which negatively impacts overall performance and efficiency, and results in poor down dispersion during modification, leading to unsatisfactory heat storage performance and surface quality, please refer to [the relevant documentation / reference needed]. Figure 1This invention provides a heat-storing down fiber surface modification device, comprising a housing 1 and a central cylinder 2 rotatably disposed within the housing 1. A cleaning tank 3, a modification tank 4, and a rinsing tank 5 are located below the central cylinder 2. Multiple electrically operated telescopic rods 6 are evenly distributed along the circumference on the surface of the central cylinder 2. A placement box 7 for loading down is rotatably mounted on the movable end of each of the electric telescopic rods 6. The placement box 7 is sequentially pushed into the cleaning tank 3, modification tank 4, and rinsing tank 5 by the electric telescopic rods 6 to achieve cleaning, soaking modification, and rinsing of the down. An inlet / outlet 101 is opened at the top of the housing 1. When the placement box 7 rotates to its highest point, the inlet / outlet 101 extends out to facilitate workers in loading and unloading down. Multiple hot air components 9, each corresponding to a placement box 7, are also provided on the surface of the central cylinder 2. The hot air components 9 are used to dry and disperse the cleaned, soaked, modified, and rinsed down. The central cylinder 2 can drive the electric telescopic rod 6 and the placement box 7 to rotate, and sequentially perform the following processes on the down: washing, drying, soaking and modifying the heat storage material, drying, rinsing to remove the modifier, and drying. This allows the modified down fiber surface to be evenly and firmly attached with the heat storage layer.

[0023] like Figure 3-Figure 5 As shown, the movable end of the electric telescopic rod 6 is fixedly equipped with a mounting bracket 601; both ends of the placement box 7 are fixedly equipped with rotating shafts 701, and bearing seats 702 are rotatably mounted on the rotating shafts 701. A locking plate 703 that engages with the end of the mounting bracket 601 is fixed on the bearing seat 702. A spring pull rod 603 for locking is provided at the end of the mounting bracket 601; the placement box 7 is also equipped with a box cover 704. The placement box 7 is made of a perforated plate to ensure that liquid can enter while preventing the down inside from escaping. When installing or removing the placement box 7, the worker pulls the spring pull rods 603 at both ends outwards and then removes the placement box 7 from the mounting bracket 601, allowing the modified down to be removed and new unmodified down to be placed inside. During the process of leaving the corresponding processing tank, the placement box 7 collides with the processing tank and flips over, causing the down inside to flip, which facilitates the drying of the hot air assembly 9.

[0024] like Figure 4 As shown, the hot air assembly 9 includes a frame 901 with a length approximately equal to that of the placement box 7. The surface of the frame 901 near the placement box 7 has multiple air outlets 902 evenly distributed in a dot-matrix pattern. A hot air blower is located on the surface of the frame 901 facing away from the placement box 7. An air inlet pipe 903 is located at the end of the frame 901. In use, outside air enters the frame 901 through the air inlet pipe 903, is heated by the hot air blower, and is then ejected from the air outlets 902 to dry the down feathers inside the placement box 7.

[0025] like Figure 4As shown, a drive mechanism 11 for rotating the central cylinder 2 is provided on the back of the housing 1. The drive mechanism 11 includes a gear ring 1101 fixedly sleeved on the end of the central cylinder 2 and a gear 1102 located on the side of the gear ring 1101 and meshing with it. A motor 1103 for driving the rotation of the gear 1102 is provided on the side of the gear 1102. In use, the motor 1103 drives the gear 1102 to rotate, the gear 1102 drives the gear ring 1101 to rotate, and the gear ring 1101 drives the central cylinder 2 to rotate.

[0026] To make the entire system more energy-efficient, such as Figure 2 , Figure 7 As shown, the back of the box 1 is also provided with three liquid filling components 12 for automatically replenishing the liquid in the cleaning tank 3, the modification tank 4 and the rinsing tank 5 respectively; the liquid filling component 12 includes a liquid storage tank 1201 and a liquid delivery pipe 1202 located at the bottom of the liquid storage tank 1201. A valve 1203 is provided on the liquid delivery pipe 1202, and a torsion spring rod 1204 is provided on the valve 1203. When the box 7 rotates, it moves the torsion spring rod 1204 to realize the opening and closing of the valve 1203. When the placement box 7 rotates under the drive of the central cylinder 2, it comes into contact with the torsion spring rod 1204 during rotation, causing the torsion spring rod 1204 to rotate and open the valve 1203. The liquid in the storage tank 1201 enters the corresponding treatment tank through the infusion pipe 1202. As the placement box 7 continues to rotate, the torsion spring rod 1204 separates from the placement box 7. Under the restoring force of the torsion spring, the valve 1203 is closed. The automatic replenishment of liquid in the treatment tank can improve the processing efficiency of the entire equipment and reduce energy consumption.

[0027] In order to accurately control the rotation angle of the central cylinder 2, such as Figure 1 , Figure 6 As shown, a positioning assembly 13 for controlling the rotation of the electric telescopic rod 6 is provided below the central cylinder 2. The positioning assembly 13 includes an arc-shaped plate 1301 fixed on the housing 1 and multiple second proximity sensors 1302 evenly distributed along the circumference and mounted on the arc-shaped plate 1301. A first proximity sensor 602 matching the second proximity sensor 1302 is provided on the side of the electric telescopic rod 6. When the first proximity sensor 602 approaches the second proximity sensor 1302, the control system of the entire equipment receives the information, controls the drive mechanism 11 to stop operating, controls the electric telescopic rod 6 to extend, and places the placement box 7 into the corresponding processing slot. This automated control results in good energy-saving performance.

[0028] Example 2 Based on Example 1, in order to improve the cleaning, soaking modification, and rinsing effects in cleaning tank 3, modification tank 4, and rinsing tank 5, such as... Figure 1 , Figure 3 As shown, the interior of the central cylinder 2 is equipped with an ultrasonic component 8 for driving the electric telescopic rod 6 and the placement box 7 to vibrate at high frequency.

[0029] A through hole is provided on the surface of the central cylinder 2 for the electric telescopic rod 6 to pass through. Support plates 201 are fixed on both sides of the through hole, and a first spring 202 is provided between the support plates 201 and the electric telescopic rod 6. The ultrasonic component 8 includes an ultrasonic generator 801 and a snap-fit ​​component 802 fixed to the vibration output end of the ultrasonic generator 801. The snap-fit ​​component 802 is snapped into the fixed end of the electric telescopic rod 6. In use, the ultrasonic generator 801 drives the snap-fit ​​component 802 to vibrate, which in turn drives the electric telescopic rod 6 to vibrate. The first spring 202 enhances the vibration effect of the electric telescopic rod 6, which in turn drives the placement box 7 to vibrate, allowing the down inside the placement box 7 to fully contact the liquid, significantly improving the modification effect of the down fibers and production efficiency.

[0030] Example 3 Based on Embodiments 1 and 2, in order to improve the drying effect of the hot air assembly 9, such as Figure 1 , Figure 8 As shown, the cleaning tank 3, the modification tank 4 and the rinsing tank 5 are all equipped with a turning mechanism 10 for tumbling and patting the placement box 7.

[0031] The actuating mechanism 10 includes a first fixed seat 1001 and a second fixed seat 1005; a lever 1002 is hinged on the first fixed seat 1001, and a mounting plate 1003 is fixedly mounted on the end of the lever 1002. A plurality of equally spaced tapping rubber rods 1004 are provided on the mounting plate 1003; an arc-shaped guide rod 1006 that movably passes through the lever 1002 is fixedly mounted on the second fixed seat 1005, and a second spring 1007 is sleeved on the arc-shaped guide rod 1006 between the lever 1002 and the second fixed seat 1005. When the central cylinder 2 drives the electric telescopic rod 6 and the placement box 7 to rotate and come into contact with the lever 1002, the lever 1002 causes the placement box 7 to tumble, thereby dispersing the down inside the placement box 7. The placement box 7 presses down on the lever 1002, at which point the lever 1002 rotates along the arc-shaped guide rod 1006, and the second spring 1007 is compressed. When the placement box 7 continues to move downward and separates from the lever 1002, the lever 1002 reciprocates under the action of the second spring 1007, thereby driving the tapping stick 1004 to continuously tap the placement box 7, further dispersing the down inside the placement box 7, preventing the down from adhering to the inner wall of the placement box 7 and affecting the modification, and greatly improving the drying effect of the hot air assembly 9.

[0032] The above-described embodiments are merely one implementation of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
