Description

Technical Field

[0001] This invention belongs to the field of fabric performance testing technology, and specifically relates to a device for testing the down-proof properties of down jacket fabrics. Background Technology

[0002] As consumers and down product manufacturers increasingly value the down-proof performance of down products, researching and innovating down-proof testing technologies for down jackets is of great practical significance for improving the quality of down products and reducing quality disputes caused by down leakage.

[0003] Existing technologies also include some technical solutions for testing the down-proof performance of down fabrics. For example, a Chinese patent with publication number CN210572309U discloses a device for testing the down-proof performance of down fabrics. This device consists of a bionic main body, a test box, a collection plate, and a control box. The bionic main body is located inside the test box and electrically connected to the control box. It tests the down-proof performance of down jackets by simulating the bionic principle of human movement, making the test data more practically meaningful. The collection plate is located between the test box and the control box to collect the down feathers that escape during the test, improving the accuracy of the down-proof performance test.

[0004] This method assesses the down-proof performance of down jackets based on the collected down. However, during the use of down jackets, there may be instances where down does not completely escape. In other words, the assessment method of this method has uncertainties and inaccuracies, making the down-proof performance test of down jackets flawed. Summary of the Invention

[0005] The purpose of this invention is to provide a device for testing the down-proof properties of down jacket fabrics in order to solve the problems mentioned in the background art.

[0006] The present invention achieves the above objectives through the following technical solutions:

[0007] A device for testing the down-proof properties of down jacket fabrics, comprising:

[0008] substrate;

[0009] Two electric actuators are mounted on the substrate;

[0010] A connector located between the output shafts of two electric actuators;

[0011] A roller is mounted on a substrate and is used to wind the fabric.

[0012] A drive motor mounted on the substrate to drive the roller shaft to rotate;

[0013] Rotating component provided on substrate; and

[0014] Adhesive portion provided on the surface of rotating component;

[0015] The roller repeatedly winds the fabric, and the adhesive part adheres to the fabric surface and rotates synchronously. The adhesive part is sticky to the fabric surface and can collect down feathers that have escaped from the fabric. The down-proof properties of the down feathers can be evaluated and tested by measuring the number of down feathers that have escaped.

[0016] Preferably, the connector has two limiting plates on the side near the roller shaft, a wave-shaped guide plate on the side of the limiting plate away from the substrate, two rotatable striking plates on the substrate, a first spring for controlling the rotation of the striking plates and the substrate, and a first roller on the side of the striking plates near the guide plate.

[0017] Preferably, a ball screw pair is provided at one end of the two striking plates that are close to each other, and a torsion member with two grippers is provided at one end of the ball screw pair that is close to the base plate. A second spring is provided between the ball screw pair and the torsion member.

[0018] Preferably, the substrate is provided with two guide sleeves, each of which is fitted with a movable plate. The two movable plates are provided with a rubbing plate for rubbing the fabric at their close ends. The two limiting plates are both set in a wave shape at their close ends. The two movable plates are provided with a second roller at their far ends. A second spring is provided between the second roller and the adjacent guide sleeve.

[0019] Preferably, the side of the rubbing board near the substrate is provided with a plurality of resistance balls for increasing the friction between the rubbing board and the fabric.

[0020] Preferably, the rotating component includes a connecting rod and a roller sleeve disposed on the surface of the connecting rod, with an adhesive portion disposed on the roller sleeve, and the roller sleeve being made of foam material or sponge.

[0021] Preferably, the adhesive part is made of tape or adhesive.

[0022] The beneficial effects of this invention are as follows:

[0023] This invention can simulate real-world usage scenarios on the fabric surface, allowing the fabric to be physically patted and rubbed. By using an adhesive object to roll on the fabric surface, down feathers that have escaped from the fabric can be recovered. The down-proof performance of the down feathers can be evaluated by the amount of down feathers recovered, avoiding test result deviations caused by down feathers not completely escaping the fabric.

Detailed Implementation

[0028] The present application will now be described in further detail. 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.

[0029] Example 1

[0030] like Figure 1-3 As shown, a down-proof fabric down-proof characteristic testing device includes:

[0031] substrate1;

[0032] Two electric actuators 2 are mounted on the substrate 1;

[0033] A connecting piece 3 is located between the output shafts of the two electric actuators 2;

[0034] A roller 4 is provided on the substrate 1, and the roller 4 is used to wind the fabric b.

[0035] A drive motor 5 is mounted on the substrate 1 to drive the roller 4 to rotate;

[0036] Rotating member 6 provided on substrate 1; and

[0037] An adhesive portion 7 is provided on the surface of the rotating part 6;

[0038] The roller 4 repeatedly winds the fabric b, and the adhesive part 7 adheres to the surface of the fabric b and rotates synchronously. The adhesive part 7 is sticky to the surface of the fabric b and can collect the down feathers that have escaped from the fabric. The down-proof properties of the down feathers can be evaluated and tested by the number of down feathers that have escaped.

[0039] It should be noted that the two ends of the down jacket fabric b to be tested are fixed to the roller 4 and the connecting piece 3 respectively. The controller controls the electric push rod 2 to move the connecting piece 3 away from the roller 4, so that one end of the fabric b is away from the roller 4, thereby straightening the fabric b. Then, the drive motor 5 drives the roller 4 to rotate, so that the fabric b is wound around the roller 4. The down fabric b is wound repeatedly to simulate the use process of the fabric b. The fabric b is in contact with the surface of the adhesive part 7. While the fabric b is wound around the roller 4, it drives the rotating part 6 and the adhesive part 7 to rotate, so that the adhesive part 7 can collect the down that has escaped from the surface of the fabric b. The amount of down on the adhesive part 7 can be used to evaluate the down-proof characteristics of the down fabric b.

[0040] Two limiting plates 8 are provided on the side of the connector 3 near the roller shaft 4. A wave-shaped guide plate 9 is provided on the side of the limiting plate 8 away from the base plate 1. Two rotatable striking plates 10 are provided on the base plate 1. A spring is provided between the striking plate 10 and the base plate 1 to control its rotation. A roller 11 is provided on the side of the striking plate 10 near the guide plate 9. During the movement of the slider, the limiting plate 8 and the guide plate 9 are moved. The wave-shaped undulation on the guide plate 9 causes the roller to move undulatingly on its surface during the movement. When the roller moves, it causes the striking plate 10 to reciprocate up and down around its rotation center. When the striking plate 10 is close to the fabric b, it vigorously strikes the surface of the fabric b, which can further simulate the impact that the fabric b is subjected to during normal use, and ultimately improve the authenticity of the down-proof test of the fabric b.

[0041] Two striking plates 10 are equipped with ball screw pairs 12 at their close ends. The end of the ball screw pair 12 closest to the base plate 1 is equipped with a torsion member 14 with two grippers 13. A second spring is located between the ball screw pair 12 and the torsion member 14. As the striking plates 10 approach the fabric b, they simultaneously drive the torsion member 14 towards the fabric b. When the torsion member 14 cannot move, it compresses the second spring, causing the ball screw pair 12 to begin operating. When the ball screw pair 12 operates, it drives the torsion member 14 to rotate. The two grippers 13 on the torsion member 14 twist the fabric b, creating rotating folds on the surface of the fabric b, further improving the accuracy of the fabric b test.

[0042] Two guide sleeves 15 are provided on the base plate 1. Each guide sleeve 15 contains a movable plate. At the ends of the two movable plates that are close to each other, there is a rubbing plate 16 for rubbing the fabric b. The sides of the two limiting plates 8 that are close to each other are both wavy. At the ends of the two movable plates that are far apart, there is a second roller 17. A second spring is provided between the second roller 17 and the adjacent guide sleeve 15. When the limiting plate 8 moves, it causes the second roller 17 to move on its wavy surface, thereby compressing the second spring and driving the movable plate and the rubbing plate 16 to reciprocate under the guidance of the guide sleeves 15. The rubbing plate 16 moves back and forth on the surface of fabric b, creating a rubbing effect. During the rubbing process, static electricity can be generated on the surface of fabric b, increasing the probability of down feathers escaping and further testing the performance of fabric b.

[0043] The rubbing plate 16 has several resistance balls 18 on the side near the substrate 1 to increase the friction between the rubbing plate 16 and the fabric b. The friction between the resistance balls 18 and the surface of the fabric b is relatively large. When the resistance balls 18 move on the surface of the fabric b, they can cause the fabric b to have a large lateral displacement and form compression and rubbing on the surface of the fabric b, thereby increasing the pores of the fabric b. Down is easier to penetrate under the rubbing, making down collection easier. When the anti-down penetration performance of the fabric b is poor, the adhesive part 7 is more likely to be covered with down.

[0044] The rotating component 6 includes a connecting rod and a roller sleeve disposed on the surface of the connecting rod. The adhesive part 7 is disposed on the roller sleeve, which is made of foam material or sponge. The roller sleeve has a large volume and compressibility, so that the adhesive part 7 on the roller sleeve is always in contact with the surface of the fabric b. Thus, during the winding process of the fabric b, the adhesive part 7 can always be driven to rotate, ensuring that the adhesive part 7 can effectively collect the down from the surface of the fabric b.

[0045] The adhesive part 7 uses tape or adhesive, with the sticky side of the tape facing outwards, so that it can collect down from the surface of the fabric b during contact.

[0046] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively 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.
