Technical Field

[0001] The utility model relates to the technical field of fabric flame retardancy testing, and particularly relates to a high-performance fabric flame retardancy testing device. Background Art

[0002] The existing fabrics are diverse and constantly evolving. Different functional requirements are needed in special working environments or for different groups of people. For example, during the use of fabrics in fire fighting, metallurgy operations, high-temperature electric welding, or electric blankets, etc., the fabrics in contact need to have good flame retardancy to improve safety performance.

[0003] With the continuous development of existing fabrics, such as in the research and development and production of PBO fiber flame retardant and wear-resistant fabrics, etc., it is necessary to test the final flame retardancy performance through a fabric flame retardancy testing device. However, the existing testing devices can only test one fabric at a time, and after the test is completed, it is necessary to re-clamp, which is rather inconvenient. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-performance fabric flame retardancy testing device, which can facilitate the batch testing of fabrics, is convenient to operate, and improves the testing efficiency.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A high-performance fabric flame retardancy testing device includes a testing box body and a specimen box body. There are several clamping parts in the specimen box body. The fabrics to be tested are clamped on the clamping parts. A transfer part is also connected in the specimen box body to transfer the fabrics to be tested into the testing box body. An ignition device is arranged in the testing box body, and the ignition device aims at the fabrics to be tested for ignition to conduct the test.

[0007] By adopting the above technical solutions, the testing box body conducts the test. The separate specimen box body is convenient for clamping multiple specimen fabrics, so as to be automatically transferred into the testing box body through the transfer part for testing, which facilitates the batch testing of fabrics and improves the testing efficiency.

[0008] Furthermore, corresponding slide rails are arranged in the testing box body and the specimen box body, and the transfer part pushes the clamping part along the slide rail into the testing box body.

[0009] By adopting the above technical solutions, it is convenient for the transfer part to push the clamping part along the slide rail into the testing box body.

[0010] Furthermore, a conveying device is arranged in the specimen box body. There are multiple slide rails arranged side by side on the conveying device. When the conveying device rotates, the slide rails on it are sequentially butted with the slide rails in the testing box body.

[0011] By adopting the above technical solution, it is convenient to transfer different fabrics in the sample box to the test box for testing.

[0012] Furthermore, the transfer member includes a pulling block that reciprocates between the test box and the sample box to pull the clamping member into the test box.

[0013] By adopting the above technical solution, the pulling block can push the clamping member to move along the slide rail.

[0014] Furthermore, a positioning groove is formed on the lower side of the clamping member, and the positioning groove penetrates through both sides of the clamping member along the conveying direction of the conveying device; the upper end of the pulling block is located on the moving path of the positioning groove when all the clamping members are conveyed on the conveying device, and the upper end of the pulling block corresponds to the position of the slide rail in the test box. When moving, only the corresponding clamping member is pulled to the position of the slide rail in the test box.

[0015] By adopting the above technical solution, while the pulling block does not affect the movement and switching of the clamping member, it can push the clamping member to move along the slide rail.

[0016] Furthermore, the pulling block is driven to move by a linear module on the side, and its moving direction is perpendicular to the conveying direction of the conveying device.

[0017] By adopting the above technical solution, linear movement of the pulling block is achieved.

[0018] Furthermore, an observation door is connected to the front of the test box, and a test box body is arranged on the side. An operation door is connected to the side of the test box body away from the test box.

[0019] By adopting the above technical solution, it is convenient to observe and clamp the fabric.

[0020] Furthermore, a baffle is provided in the sample box, and the baffle is arranged between the fabric to be tested and the tested fabric, dividing the sample box into a completed side and a to-be-determined side. The clamping member is located above the baffle. When the clamping member moves to the completed side, the fabric to be tested below it remains on the to-be-determined side through the baffle, and then the clamping member moves to the test box through the transfer member.

[0021] By adopting the above technical solution, it is convenient to separate the fabric to be tested and the tested fabric, and avoid accidental combustion in the sample box.

[0022] In summary, the utility model has the following beneficial effects:

[0023] The test box is used for testing. The separate sample box is convenient for clamping multiple sample fabrics, so that they can be automatically transferred to the test box through the transfer member for testing, facilitating batch testing of fabrics and improving testing efficiency;

[0024] The test box body and the sample box body are provided with corresponding slide rails. The transfer piece pushes the clamping piece along the slide rail into the test box body, which facilitates the transfer piece to push the clamping piece along the slide rail into the test box body. The sample box body is provided with a conveying device, and a plurality of slide rails arranged in parallel are provided on the conveying device. When the conveying device rotates, the slide rails thereon are sequentially docked with the slide rails in the test box body, and the pulling block can push the clamping piece to move along the slide rail, which can push the clamping piece to move along the slide rail while not affecting the movement and switching of the clamping piece.

[0032] As Figure 1 and Figure 2As shown, in order to realize the movement of the clamping member 3, corresponding slide rails 5 are fixed in the test box body 1 and the specimen box body 2. The transfer member pushes the clamping member 3 along the slide rail 5 into the test box body 1. A conveying device 6 is provided in the specimen box body 2. A plurality of slide rails 5 arranged side by side are provided on the conveying device 6. When the conveying device 6 rotates, the slide rails 5 thereon are sequentially docked with the slide rails 5 in the test box body 1;

[0033] In this embodiment, the slide rail 5 is an inverted T shape, and a corresponding T-shaped groove is opened at the top of the clamping member 3; the conveying device 6 is a structure such as a synchronous belt or a chain plate conveyor belt. A plurality of slide rails 5 are fixed along the length direction on the outside. The slide rails 5 are fixed by means such as bonding or bolt connection. After the conveying device 6 conveys the slide rails 5 thereon to be aligned with the slide rails 5 in the test box body 1, it stops, waits for the transfer member to move the clamping member 3 thereon back and forth, and then continues to convey forward until the next slide rail 5 is aligned with the slide rails 5 in the test box body 1.

[0034] As Figure 3 shown, the transfer member includes a pulling block 7. The pulling block 7 reciprocates between the test box body 1 and the specimen box body 2 to pull the clamping member 3 into the test box body 1; in this embodiment, the pulling block is set as a U shape or a vertical knife shape.

[0039] During the test, although the clamping member 3 moves to the completion side, the fabric to be tested below it remains on the pending side through the baffle 22. Then, the clamping member 3 moves into the test box body 1 through the transfer member. After the test is completed, the clamping member 3 resets to the position on the completion side, and the fabric below it drops onto the completion side by its own weight, realizing the separation from the pending side.
