Description

Technical Field

[0001] The invention relates to the technical field of down jacket fabric testing, and in particular to a down jacket fabric anti-down drilling property testing device. Background Art

[0002] A down jacket is a jacket filled with down filling. It is large and round in shape. Down jackets have the best warmth retention. Most of them are worn by people in cold areas and are also often used by polar surveyors.

[0003] During the production process of down jackets, duck down is stuffed into the fabrics. After the fabrics are sewn, the duck down can be locked in the clothes to keep warm. After the duck down enters the fabrics, in order to prevent the down from drilling into the fabrics, the down jacket fabrics need to be tested. At present, the down jacket fabrics need to be folded and polished many times during testing, which requires the operator to place the down jacket fabrics in the folding equipment for repeated folding, and put the down jacket fabrics that have been folded a certain number of times into the polishing equipment for polishing. This testing method requires the use of a variety of testing instruments, which increases the operating cost. In order to maximize the detection of the anti-drilling properties of the down jacket fabrics during testing, the operator will manually pull the down jacket fabrics to keep the down jacket fabrics in a taut state during testing. The manually supported down jacket fabrics cannot guarantee their own stability during testing. If the down jacket fabrics fall off, this will lead to errors in the anti-drilling test results of the down jacket fabrics, affecting the accuracy of the down jacket fabric testing, thereby reducing the efficiency of the down jacket fabric testing.

The pressure plate 11 can initially limit the down jacket fabric. After the output end of the telescopic rod 14 is extended, it can drive the clamp plate 15 to extend to the down jacket fabric, so that the down jacket fabric does not need to be manually supported by the operator during detection;

[0034] A connected frame 17 is fixedly installed on one side of the platform 3, and a moving component for driving the active seat 6 and folding the down jacket fabric is installed in the frame 17;

[0035] The moving assembly includes two connecting plates 21 fixedly mounted on the two active seats 6, and a rack 22 is fixedly mounted on the connecting plates 21, a motor 18 is fixedly mounted in the frame 17, and a rotating shaft 19 connected to the rack 22 is fixedly connected to the output end of the motor 18, the rotating shaft 19 is vertically arranged, and a gear 20 meshing with the two racks 22 is fixedly mounted on the rotating shaft 19, and the racks 22 are horizontally arranged on both sides of the gear 20. Figure 4 As shown, the two racks 22 will not collide when moving toward or in opposite directions;

[0036] After the motor 18 is driven, when the two active seats 6 move toward or in the opposite direction, the driven seat 7 is driven to move through the traction rod 8, so that the two corresponding active seats 6 and the driven seat 7 can fold the down jacket fabric when moving. After the motor 18 is powered on, it drives the rotating shaft 19 to rotate forward and reversely in the frame 17. This technical solution is a prior art and will not be elaborated on here.

[0037] A support rod 16 is fixedly mounted on the test bench 1, and a hydraulic cylinder 23 is fixedly mounted on the support rod 16. The output end of the hydraulic cylinder 23 is fixedly connected to a sealing cover 24 corresponding to the platform body 3, and the pipeline 2 is arranged on the sealing cover 24. After the hydraulic cylinder 23 is energized, it can drive the sealing cover 24 to move downward and extend to the platform body 3, so that the airflow in the pipeline 2 can be quickly sprayed onto the down jacket fabric.

[0039] The friction assembly includes a motor 25 fixedly mounted on the sealing cover 24, and a bidirectional screw rod 1 26 is fixedly connected to the output end of the motor 25, a bidirectional screw rod 27 which is transmission-connected to the bidirectional screw rod 1 26 is rotatably mounted on the sealing cover 24, two matching nuts 29 are slidably sleeved on the bidirectional screw rod 1 26 and the bidirectional screw rod 2 27, a connecting rod 30 is connected to the nut 29, and a connecting frame is provided between the two corresponding connecting rods 30, and a roller 31 for rubbing the down jacket fabric is provided on the connecting frame;

[0040] The bidirectional screw rod 1 26 and the bidirectional screw rod 2 27 are arranged horizontally correspondingly, and a transmission belt 28 is connected between the bidirectional screw rod 1 26 and the bidirectional screw rod 2 27. The two ends of the connecting rod 30 are respectively connected to the connecting frame and the nut 29 by pins. A guide plate is fixedly installed on the nut 29, and a limit rod corresponding to the guide plate is installed in the frame 17. The movement direction of the nut 29 can be limited by the mutual cooperation between the guide plate and the limit rod.

[0041] After the motor 25 is powered on, it drives the bidirectional screw rod 1 26 to rotate on the sealing cover 24, and the roller 31 can rotate on the connecting frame after being powered on. The technical solution is the existing technology and will not be elaborated in detail here.

[0042] The active seat 6 and the driven seat 7 can clamp the down jacket fabric, and then the motor 18 drives the down jacket fabric to be folded, and then the motor 25 drives the roller 31 to extend onto the down jacket fabric, so that the test bench 1 as a whole can detect the anti-down drilling characteristics of the down jacket fabric, which not only improves the adaptability of the test bench 1, but also improves the efficiency of down jacket fabric detection;

[0043] It should be noted that when the down jacket fabric is folded, the sealing cover 24 is located above the table 3. When the friction degree of the down jacket fabric needs to be tested, the down jacket fabric is in a taut state, which means that the active seat 6 and the driven seat 7 can be respectively located at the four corners of the table 3, and will not collide with the roller 31.

[0044] The present invention can be explained by the following operation mode:

[0045] The down jacket fabric is cut and placed in the platform 3;

[0046] The movable plate 12 is pulled so that the movable plate 12 slides in the holder 9 and drives the pressure plate 11 to move upward. The spring 13 is stressed and the four corners of the down jacket fabric are extended to the active seat 6 and the driven seat 7 respectively.

[0047] Release the traction on the movable plate 12, and under the action of the spring 13, the pressure plate 11 moves down and initially limits the down jacket fabric. The output end of the telescopic rod 14 drives the clamp plate 15 to move down, so that the clamp plate 15 can limit the down jacket fabric in the clamp seat 9;

[0048] When testing down jacket fabrics, the down jacket fabrics must first be folded repeatedly;

[0049] The output end of the motor 18 drives the rotating shaft 19 to rotate forward and reversely, so that the rotating shaft 19 drives the gear 20 to pull the meshing rack 22. When the rack 22 moves toward or in the opposite direction, it drives the two active seats 6 to move toward or in the opposite direction through the connecting plate 21. When the active seat 6 moves toward or in the opposite direction on the guide rod 1 4, it drives the driven seat 7 to move through the traction rod 8, so that the down jacket fabric can be repeatedly folded when the driven seat 7 slides on the guide rod 2 5;

[0050] When the down jacket fabric is folded a certain number of times, the motor 18 unfolds the down jacket fabric during operation, and then the motor 18 stops driving;

[0051] The output end of the hydraulic cylinder 23 drives the sealing cover 24 to move downward, so that the sealing cover 24 extends to the platform 3, and the output end of the motor 25 drives the bidirectional screw rod 1 26 to rotate, and the bidirectional screw rod 1 26 drives the bidirectional screw rod 2 27 to rotate through the transmission belt 28. When the bidirectional screw rod 1 26 and the bidirectional screw rod 2 27 rotate, they pull the two nuts 29 to move in the opposite direction or opposite direction;

[0052] When the two nuts 29 move toward each other, the traction connecting rod 30 deflects, and the position difference generated when the connecting rod 30 deflects can exert pressure on the connecting frame, so that the connecting frame drives the roller 31 to extend onto the down jacket fabric;

[0053] The roller 31 can generate friction with the down jacket fabric when rotating;

[0054] After the down jacket fabric has been rubbed for a certain period of time, the roller 31 stops driving, and the motor 25 drives the frame 17 back to the initial position;

[0055] Then, the motor 18 is turned on again, so that the active seat 6 and the driven seat 7 pull the down jacket fabric from both sides, so that the down jacket fabric is in a taut state;

[0056] When the fan is turned on, the airflow enters the platform 3 through the pipe 2 and extends to the down jacket fabric;

[0057] The down in the down jacket fabric will be intercepted by the filter in the platform 3;

[0058] After the down jacket fabric is inspected, the sealing cover 24 returns to the initial position, the down jacket fabric is removed from the holder 9, and the operator checks the down content in the platform 3 to determine whether the down jacket fabric is qualified.

[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
