Description

Technical Field

[0001] The present invention relates to the technical field of fabric air permeability detection, and specifically to a device for detecting the air permeability of fabrics used in textiles. Background Art

[0002] The air permeability of fabrics is an important indicator to measure the air permeability state of fabrics, which is directly related to the comfort and health of the wearer. Therefore, it is of great significance to carry out fabric air permeability tests. First, through testing, the air permeability performance of fabrics can be objectively evaluated, providing a basis for fabric design and material selection. Second, the test results can guide fabric production and processing technologies to improve the air permeability performance of fabrics.

[0003] However, in the prior art, when detecting fabrics, a part of the fabric can be cut off for detection, but this will cause certain waste of the fabric. When using a longer fabric for detection, it will take a long time for the operator to flatten the fabric, resulting in a long time required for the operator to perform preparatory work and reducing work efficiency.

[0004] At the same time, when detecting fabrics in the prior art, when pressing the fabric, it is easy to have misoperations, resulting in the pressing mechanism accidentally injuring the operator during work, affecting the personal safety of the operator and resulting in low safety during detection in the prior art.

[0005] Moreover, after detecting the fabric in the prior art, it is necessary for the operator to manually collect and organize the fabric, increasing the workload of the operator. When it is necessary to detect the air permeability of a large amount of fabric, it is necessary to remove the fabric and then replace it with a new fabric for detection. Due to the inconvenience of quickly collecting and organizing the fabric, the existing detection equipment is relatively inconvenient to use. Summary of the Invention

The upward movement of the third bolt can drive the second clamping plate to move upward synchronously, so that the second clamping plate can cooperate with the first clamping plate to clamp one end of the fabric. The operator arranges the other end of the fabric, and at the same time controls the double-headed motor to work, so that the four rotating rods drive the second support blocks to expand to both sides.

The output shaft of the first motor drives the frame body to rotate, so that the frame body can drive the arc plates on both sides to rotate synchronously by less than 90°, then stop the first motor, and wind the fabric to the middle part between the two vertical plates, so that the wrinkles on the surface of the detection platform can be stretched out, and the fabric can be laid flat on the upper surface of the detection platform.

[0021] Through the cooperation of the docking device, the pressing plate, the first disc and the second disc, the telescopic end of the cylinder shortens to drive the circular plate to move, so that the circular plate can drive the docking sleeve to slide on the outer wall of the rotating shaft, so that the docking sleeve can be sleeved on the outer wall of the docking rod for clamping. Control the second motor to work, so that the output shaft of the second motor rotates to drive the docking rod to rotate, so that the docking rod can drive the docking sleeve to rotate synchronously, so that the docking sleeve can drive the rotating shaft to rotate, and the rotating shaft can drive the bent block to move synchronously, so that the bent block can drive the pressing plate to rotate around the rotating shaft, and the pressing plate can drive the first circular plate to move to a state of being close to the second disc, stop the rotation of the rotating shaft, and at the same time stop the second motor. The first circular plate and the second disc can press the fabric. After the detection is completed, according to the above operation, the pressing plate is returned to its original position, so that the pressing plate fits the side of the fabric air permeability tester body, and at the same time the docking rod and the docking sleeve are separated, preventing accidental injury to the operator caused by accidental operation. By being in a disconnected state when not pressed, the safety hazard caused by accidental operation can be effectively avoided, and the safety is improved.

[0022] Through the cooperation of the auxiliary collection device, the frame and the detection platform, start the first motor to continue rotating, so that the fabric is completely wound onto the outer walls of the frame and the arc plates on both sides. Stop the first motor. The operator pulls the handrail so that the vertical plate can move, and the vertical plate can slide on the outer walls of the straight rods on both sides. At the same time, the vertical plate can compress the spring, and at the same time, the turntable can be separated from the sliding rod. According to the above operations, the arc plates on both sides retract inward, creating a gap between the fabric and the frame. The fabric can be drawn out through the gap between the frame and the vertical plate, facilitating the operator to collect it. Release the handrail, so that the springs on both sides are no longer compressed. Under the push of the springs on both sides, the vertical plate can be pushed back to its original position, and the turntable can be engaged with the sliding rod again. Removing the collected and sorted fabric can facilitate the operator to quickly collect and sort it, making the present invention more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Flattening process:

[0052] The operator places one end of the longer fabric between the first clamping plate 25 and the second clamping plate 24, and rotates the third bolt 10. Under the action of the thread between the third bolt 10 and the frame 23, the third bolt 10 can move upward. The upward movement of the third bolt 10 can drive the second clamping plate 24 to move upward synchronously, so that the second clamping plate 24 can cooperate with the first clamping plate 25 to clamp one end of the fabric. The operator arranges the other end of the fabric, and at the same time controls the double-headed motor 904 to work, so that the output shafts on both sides of the double-headed motor 904 can drive the threaded rods 903 on both sides to rotate, so that the threaded rods 903 on both sides can drive the threaded blocks 905 on both sides to move synchronously, so that the threaded blocks 905 on both sides can move relatively. The threaded blocks 905 on both sides can drive a plurality of first support blocks 902 to move synchronously, so that the first support blocks 902 can drive one end of the four rotating rods 907 to move, so that the four rotating rods 907 drive the second support block 908 to expand to both sides. The second support block 908 can drive the two arc plates 901 to expand. At the same time, control the first motor 11 to work. The output shaft of the first motor 11 drives the frame 23 to rotate, so that the frame 23 can drive the two arc plates 901 on both sides to rotate synchronously by less than 90° and then stop the first motor 11. The fabric is wound to the middle part between the two vertical plates 26, so that the wrinkles of the fabric on the surface of the detection platform 12 can be stretched out, so that the fabric can be laid flat on the upper surface of the detection platform 12, and at the same time the fabric covers the second disc 14.

[0053] Pressing process:

[0054] The external power supply of the control cylinder 205 is started, and the telescopic end of the cylinder 205 is shortened to drive the circular plate 206 to move, so that the circular plate 206 can drive the docking sleeve 204 to slide on the outer wall of the rotating shaft 208, so that the docking sleeve 204 can be sleeved on the outer wall of the docking rod 203 for clamping, and the second motor 201 is controlled to work, so that the output shaft of the second motor 201 rotates to drive the docking rod 203 to rotate, so that the docking rod 203 can drive the docking sleeve 204 to rotate synchronously, so that the docking sleeve 204 can drive the rotating shaft 208 to rotate, and the rotating shaft 208 can drive the bending block 209 to move synchronously, so that the bending block 209 can drive the pressing plate 7 to rotate with the rotating shaft 208 as the center, and the pressing plate 7 can drive the first circular plate 15 to move to a state of being close to the second disc 14, so that the rotating shaft 208 stops rotating, and the second motor 201 is stopped at the same time, and the first circular plate 15 and the second disc 14 can press the cloth.

[0055] Testing process:

[0056] The fabric air permeability tester body 5 is controlled to work, and the fabric air permeability tester body 5 sucks air from the second disc 14 through a pipe, so that air can pass through the cloth and the first disc 15 and enter the fabric air permeability tester body 5. The fabric air permeability tester body 5 can display the test result through the display screen 4. After the test is completed, according to the above operation, the pressing plate 7 is returned to its original position, so that the pressing plate 7 is fitted with one side of the fabric air permeability tester body 5, and the docking rod 203 and the docking sleeve 204 are separated at the same time to prevent accidental injury to the operator due to compression caused by misoperation.

[0057] Fabric collection and sorting process:

[0058] The first motor 11 is started to continue rotating, so that the cloth is completely rolled up to the outer wall of the frame 23 and the arc plates 901 on both sides, and the first motor 11 is stopped. The operator pulls the handrail 808 to move the vertical plate 801, so that the vertical plate 801 can slide on the outer wall of the straight rod 804 on both sides, and the vertical plate 801 can compress the spring 803, and the rotating disk 806 can be separated from the sliding rod 807. According to the above operation, the arc plates 901 on both sides are retracted inward, so that the cloth and the frame are rolled up. There may be a gap between the frame body 23. According to the above operation, the first clamping plate 25 and the second clamping plate 24 are separated so that the first clamping plate 25 and the second clamping plate 24 no longer clamp the cloth. The cloth can be drawn out through the gap between the frame body 23 and the vertical plate 801, which is convenient for the operator to collect. The armrest 808 is loosened so that the springs 803 on both sides are no longer compressed. Under the push of the springs 803 on both sides, the vertical plate 801 can be pushed to reset, so that the turntable 806 can be clamped with the slide rod 807 again.

[0059] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art will appreciate that various changes in form and detail may be made within the scope of the claims.
