Description

Technical Field

[0001] The utility model relates to the technical field of textile detection, in particular to a fabric moisture permeability meter. Background Art

[0002] The moisture permeability of fabrics is measured by the moisture permeability cup method to determine the ability of water vapor to pass through fabrics. This instrument is used to measure the moisture permeability of various fabrics and non-woven fabrics such as cotton wool and space cotton used for clothing. Moisture permeability can reflect the performance of clothing in wicking sweat and vapor, and is one of the important indicators for identifying the comfort and hygiene of clothing.

[0003] The application number is 200610125314.X, and the invention name is "A fabric moisture permeability testing device". The Chinese patent document discloses a simple and effective testing device, but the testing device needs to use external objects to regulate the environment, has poor coordination and unification performance, and is complicated to operate. In addition, the testing device can only perform a single experiment in a single experimental operation, with low experimental efficiency and slow experimental progress.

[0004] In addition, during actual use, when the above-mentioned device is placed on the fabric, since the surface of the fabric will adhere to moisture during the detection process, when the moisture on the surface of the fabric increases, the fabric is likely to sink due to gravity, which will affect the accuracy of the detection result. Utility Model Content

[0005] The utility model aims to provide a fabric moisture permeability meter to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solutions: a fabric moisture permeability meter, comprising a fabric moisture permeability meter body, wherein a driving component for hanging fabric and allowing the fabric to swing inside the fabric moisture permeability meter body is installed at the top of the fabric moisture permeability meter body;

[0007] Buffering parts for limiting the downward movement of fabrics are respectively installed in the middle of both sides of the inner wall of the fabric moisture permeability meter body;

[0008] When the fabric swings in the fabric moisture permeability meter body, the moisture on the fabric surface increases. When the moisture on the fabric surface increases, the bottom of the driving component is driven to move downward. When the driving component moves downward, the action of swinging the fabric is stopped, and the two ends of the driving component are respectively plugged into the two buffers during the downward movement.

[0009] The driving component comprises:

[0010] A swing motor is installed at the top of the outside of the fabric moisture permeability meter body, the output end of the swing motor passes through the top of the fabric moisture permeability meter body and is fixed with a connecting piece, the two ends of the bottom of the connecting piece are respectively fixed with bearing blocks, the bearing block is the bottom of the driving component, a right-angle arm plugged with the buffer is fixed on one side of the outer side of the bearing block close to the inner wall of the fabric moisture permeability meter body, and the bearing block can hang a hanger for placing fabrics.

[0011] Furthermore, the connecting member is a bidirectional electric push rod, and two output ends of the bidirectional electric push rod are respectively fixed with assembly blocks, and the bottom of the assembly block is fixed to the top of the bearing block;

[0012] A spring is installed between the top of the bidirectional electric push rod and the top of the inner wall of the fabric moisture permeability meter body.

[0013] Furthermore, a gravity sensor is installed on one end of the outside of the assembly block away from the bidirectional electric push rod, and the gravity sensor is electrically connected to the bidirectional electric push rod.

[0014] Furthermore, a notch is provided at the bottom of the bearing block, and a stress-bearing rod for hanging a clothes hanger is installed at the notch of the bearing block.

[0015] Furthermore, the buffer comprises: a force-bearing block, one side of which is fixed to the inner wall of the fabric moisture permeability meter body, and the other side of the force-bearing block is fixed with a right-angle limit fork, the fork of which is matched with the right-angle arm.

[0016] Furthermore, a communication opening is provided at a position of the top of the right-angle limiting fork close to the force-bearing block, and the communication opening is matched with the bottom of the right-angle arm.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The fabric moisture permeability meter uses a hooked fabric method to replace the current method of placing the fabric inside the fabric moisture permeability meter for testing. The design not only effectively solves the problem that the fabric is prone to sinking due to excessive surface moisture during the testing process of the existing fabric moisture permeability meter, but also improves the testing efficiency, making the testing process more convenient and reliable.

[0019] In addition, the utility model is also designed with a buffer. When the moisture on the surface of the fabric increases and drives the driving component to move downward, the buffer can effectively limit the downward movement of the fabric, thereby preventing the fabric from excessively sagging due to gravity, ensuring that the fabric swings more evenly in the moisture permeability meter and the test result is more accurate.

[0020] At the same time, when the driving component moves down and engages with the two buffer components, the driving component stops the action of swinging the fabric, which also helps to ensure the stability and accuracy of the detection results. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The working principle of the fabric moisture permeability meter is mainly based on the humidity difference method. The fabric moisture permeability meter divides the sample into two climate chambers to make the indoor and outdoor humidity different, so as to observe the water vapor transmission caused by the humidity difference. The moisture permeability tester is equipped with a high-precision sensor, which can accurately measure the water vapor pressure difference in the sample. During the test process of the existing fabric moisture permeability meter, the fabric sample to be tested is fixed on the tester, and the corresponding test conditions, such as temperature, humidity, etc., are set. The tester allows air to penetrate from one surface to another through a certain pressure difference, and then measures the amount of moisture that penetrates the fabric. According to the measurement results, the moisture permeability and breathability performance indicators of the fabric, such as breathability resistance, ventilation rate, etc., can be obtained. Therefore, during the actual detection process, water will adhere to the surface of the fabric, and the attachment of water will increase the weight of the fabric, so that under the action of gravity, the fabric will sink, which will reduce the contact area between the fabric surface and moisture, thereby reducing the detection accuracy.

[0027] like Figure 1 - Figure 3As shown, the utility model provides a technical solution: a fabric moisture permeability meter, comprising a fabric moisture permeability meter body 1, a driving component 6 for hanging fabric and swinging the fabric inside the fabric moisture permeability meter body 1 is installed at the top of the fabric moisture permeability meter body 1; buffers 5 for limiting the downward movement of the fabric are respectively installed at the middle of both sides of the inner wall of the fabric moisture permeability meter body 1; when the fabric swings in the fabric moisture permeability meter body 1, the moisture on the surface of the fabric increases, and when the moisture on the surface of the fabric increases, the bottom of the driving component 6 is driven to move downward, and when the driving component 6 moves downward, the action of swinging the fabric is stopped, and the fabric is moved downward. During the shifting process, the two ends of the driving component 6 are respectively plugged into the two buffers 5; it should be noted that in the present application, the driving component 6 includes: a swing motor 601, which is installed at the top of the outside of the fabric moisture permeability meter body 1, and the output end of the swing motor 601 passes through the top of the fabric moisture permeability meter body 1 and is fixed with a connecting piece, and the two ends of the bottom of the connecting piece are respectively fixed with a bearing block 603, the bearing block 603 is the bottom of the driving component 6, and a right-angle arm 606 plugged into the buffer 5 is fixed on the outer side of the bearing block 603 close to the inner wall of the fabric moisture permeability meter body 1, and the bearing block 603 can hang a hanger for placing fabrics.

[0028] It should be noted that the reference Figure 1 It can be seen that in the present application, the instrument door panel of the fabric moisture permeability meter body 1 is equipped with an observation window 4, a force handle 2 and a control panel 3 for controlling the fabric moisture permeability meter body 1, a swing motor 601 and a bidirectional electric push rod 604.

[0029] It should also be added that, since the fabric moisture permeability meter body 1 is a common testing device for testing fabrics, the applicant does not make specific restrictions on the internal structure, working principle and specific model of the fabric moisture permeability meter body 1.

[0030] In addition, reference Figure 2 and Figure 3It can be seen that in the present application, the connecting member is a bidirectional electric push rod 604, and the two output ends of the bidirectional electric push rod 604 are respectively fixed with assembly blocks 602, and the bottom of the assembly block 602 is fixed to the top of the supporting block 603; a spring is installed between the top of the bidirectional electric push rod 604 and the top of the inner wall of the fabric moisture permeability meter body 1. It should be noted that in the present application, a gravity sensor is installed at one end of the assembly block 602 away from the bidirectional electric push rod 604, and the gravity sensor and the bidirectional electric push rod 604 are electrically connected. A notch is provided at the bottom of the bearing block 603, and a force-bearing rod 605 for hanging a hanger is installed at the notch of the bearing block 603. It should be added that, in the present application, the buffer member 5 includes: a force-bearing block 501, one side of the force-bearing block 501 is fixed to the inner wall of the fabric moisture permeability meter body 1, and a right-angle limit fork 502 is fixed to the other side of the force-bearing block 501, and the fork of the right-angle limit fork 502 is adapted to the right-angle arm 606. It should be noted that a connecting port 503 is provided at the top of the right-angle limit fork 502 near the force-bearing block 501, and the connecting port 503 is adapted to the bottom of the right-angle arm 606.

[0031] It should be noted that when the device is actually used, its operation process is as follows:

[0032] First, the fabric to be tested is hung in the force-bearing rod 605 on the bearing block 603, and then the swing motor 601 is started. The swing motor 601 drives the fabric on the bearing block 603 and the force-bearing rod 605 to swing inside the fabric moisture permeability meter body 1. During the swinging process of the fabric, water will gradually adhere to the surface of the fabric, and the adhesion of water will increase the weight of the fabric, so that under the action of gravity, the fabric will sink. At this time, the gravity sensor will detect the weight change of the bearing block 603 and transmit the signal to the bidirectional electric push rod 604. After receiving the signal, the bidirectional electric push rod 604 will shorten the distance between its two output ends, thereby driving the fabric on the bearing block 603 and the force-bearing rod 605 to move up and return the fabric to the initial position. At this time, the driving component 6 will continue to swing the fabric, and this is repeated until the detection is completed. It should be noted that when the detection is completed, the bidirectional electric push rod 604 will return to the original position. Figure 1 The position shown in the figure allows the right angle limit fork 502 and the right angle arm 606 to be plugged into each other.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
