Description

Technical Field

[0001] This application relates to a testing device, and more particularly to a high-temperature resistance testing device for flame-retardant fabrics. Background Technology

[0002] After the flame-retardant fabric is prepared and formed, in order to ensure that the product meets the standards, a high-temperature resistance test is generally required before leaving the factory to verify whether the flame-retardant and high-temperature resistance performance of the fabric is qualified.

[0003] When testing the high-temperature resistance of flame-retardant fabrics using existing technologies, mild pressure conditions such as ironing and pressure are often simulated. The critical damage temperature of the fabric is determined by a gradient heating method, and the corresponding testing standard is GB / T 13767 Pressure Heat Resistance Method.

[0004] Currently, most flame-retardant fabric testing equipment relies on manual operation: the operator places the fabric to be tested face-up on a heating plate, then drives the heating plate upwards, pressing the fabric onto a hot ironing plate to complete the high-temperature resistance test. However, flame-retardant fabrics are soft, and the length of a single sample is often close to 1 meter, which significantly prolongs the operation time of laying the fabric flat, resulting in a significant reduction in testing efficiency. At the same time, the heating plate uses a resistance heating mode, and the working temperature of the plate surface is high, which can easily pose a safety hazard to the operator.

[0015] According to one embodiment of this application, the side-pull drive component includes a side-pull motor, a lead screw, and a side slider, wherein the side slider is confined to the transverse guide rail, wherein the lead screw is arranged parallel to the transverse guide rail and is rotatably connected to the side-pull motor, the side slider can slide along the transverse guide rail as the lead screw rotates, and the side-pull component is mounted on the side slider.

[0033] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0034] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0035] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0036] refer to Figures 1 to 5 According to a preferred embodiment of the present invention, a high-temperature resistance testing device for flame-retardant fabrics is provided, wherein the high-temperature resistance testing device for flame-retardant fabrics includes a heat resistance testing component 10, a pressing component 20, and a side-pulling component 30.

[0037] Specifically, the heat resistance testing component 10 includes a heating plate 11 and a fixing plate 12, wherein a testing space 101 is formed between the heating plate 11 and the fixing plate 12, wherein the heating plate 11 or the fixing plate 12 is movably connected to the pressing component 20, thereby being able to press the flame-retardant fabric 900 to be tested located in the testing space 101.

[0038] Those skilled in the art will understand that the width of the flame-retardant fabric is no greater than the width of the heating plate 11. The side-pulling assembly 30 is configured to pull the flame-retardant fabric 900 to be tested, located outside the detection space 101, into the detection space 101 from the length direction of the heating plate 11, thereby performing high-temperature resistance testing on the flame-retardant fabric 900 located in the detection space 101 when the fixing plate 12 and the heating plate 11 of the heat resistance testing assembly 10 are in contact with each other.

[0039] Those skilled in the art will understand that after the heating plate 11 and the fixing plate 12 clamp the flame-retardant fabric 900 to be tested, the heating plate 11 can gradually heat up, thereby pressing the flame-retardant fabric 900 located in the testing space 101. This is done by increasing the temperature by 10-20°C each time, and then opening the testing space 101. Once a preset temperature is reached, the high-temperature resistance range of the flame-retardant fabric 900 can be detected by observing whether it exhibits melting, sticking, yellowing, or damage.

[0040] For example, in one embodiment, the flame-retardant fabric 900 to be tested is pressed from 200°C. When it reaches 300°C, the flame-retardant fabric 900 to be tested is still not damaged. The temperature is increased by 20°C each time. When it reaches 320°C, the flame-retardant fabric 900 to be tested turns yellow. Therefore, the high temperature resistance range of the flame-retardant fabric 900 to be tested is 300°C to 320°C.

[0041] Those skilled in the art will understand that since the flame-retardant fabric 900 to be tested is pulled into the testing space 101 from the length direction of the heating plate 11, i.e., from the side, by the side-pulling component 30, it is not necessary to manually lay the fabric on the heating plate 11. In this way, not only can the testing efficiency be effectively improved, but also the staff can be prevented from directly contacting the heating plate 11 and from being burned by the heating plate 11.

[0042] Those skilled in the art will understand that the heating plate 11 includes a heat-conducting plate, such as a copper plate, and a heating resistor encased within the copper plate. When the heating resistor is energized, it heats the heat-conducting plate, thereby enabling the heating plate 11 to reach a predetermined temperature. It is worth noting that the heat resistance detection component 10 also includes a temperature sensor, which is configured to detect the temperature reached by the heating plate 11.

[0043] In a preferred embodiment, the heating plate 11 is vertically movably connected to the pressing assembly 20, wherein the fixing plate 12 is fixedly held at a predetermined height from the heating plate 11. Thus, when the heating plate 11 is driven by the pressing assembly 20 to approach the fixing plate 12 vertically, the flame-retardant fabric being detected in the detection space 101 between the fixing plate 12 and the heating plate 11 will be pressed.

[0044] In one embodiment, the pressing assembly 20 includes a vertical guide rail 21, a vertical slider 22 movable up and down along the vertical guide rail 21, and a vertical driving member 23, wherein the vertical slider 22 is movably connected to the vertical driving member 23 in a vertical direction, thereby enabling the vertical slider 22 to be driven to slide along the vertical guide rail 21 in a vertical direction.

[0045] The heating plate 11 is mounted on the vertical slider 22, so that the heating plate 11 can move closer to or further away from the fixed plate 12 as the vertical slider 22 moves up and down.

[0046] In a preferred embodiment, the vertical drive component 23 includes a drive motor 231, a worm gear 232, and a connecting rod 233. One end of the connecting rod 233 is hinged to the worm gear 232, and the other end is hinged to the vertical slider 22. The worm gear 232 is rotatably connected to a worm wheel on the output shaft of the drive motor 231. Thus, as the drive motor 231 operates, the worm gear 232 can be driven to rotate. Correspondingly, the connecting rod 233 will cause the vertical slider 22 to slide up and down along the vertical guide rail 21.

[0047] Furthermore, the side-pull assembly 30 includes a transverse guide rail 31 extending along the length of the heating plate 11, a side-pull member 32, and a side-pull drive member 33. The side-pull member 32 is configured to be driven by the side-pull drive member 33 to slide back and forth along the transverse guide rail 31. The side-pull member 32 is configured to clamp one end of a flame-retardant fabric laid flat from one side of the detection space 101, and then, driven by the side-pull drive member 33, lay the flame-retardant fabric 900 to be tested onto the heating plate 11 along the extension direction of the heating plate 11. Those skilled in the art will understand that, in this way, the flame-retardant fabric 900 to be tested does not need to be manually laid on the heating plate 11 by personnel.

[0048] Specifically, the side tension member 32 includes a mounting body 321 and at least one side tension arm 322.

[0049] Each of the side pull arms 322 includes a first clamping arm 3221, a second clamping arm 3222, and at least one drive unit 3223, wherein the first clamping arm 3221 and / or the second clamping arm 3222 are rotatably mounted to the mounting body 321 to form a clamping opening 322201 between the first clamping arm 3221 and the second clamping arm 3222, wherein at least one of the first clamping arm 3221 or the second clamping arm 3222 is drivably connected to the drive unit 3223, thereby forming an openable and closable clamping opening 322201 between the first clamping arm 3221 and the second clamping arm 3222.

[0050] Preferably, the side-pull member 32 includes a pair of side-pull arms, wherein the pair of side-pull arms 322 are spaced apart on the mounting body 321 along a longitudinal direction perpendicular to the length direction of the heating plate 11. The distance between the pair of side-pull arms 322 is not less than the width of the heating plate 11 along the longitudinal direction, so that when the pair of side-pull members 32 slide along the transverse guide rail 31, they will never be interfered with by the heating plate 11.

[0051] In this way, when the flame-retardant fabric 900 to be tested needs to be dragged into the testing space 101, one end of the flame-retardant fabric 900 can be clamped by the pair of side pull arms 322 of the side pull member 32. Subsequently, the side pull drive member 33 can drive the side pull member 32 to slide along the transverse guide rail 31, thereby driving the side pull member 32 to slide along the length direction of the heating plate 11, thus dragging the flame-retardant fabric 900 to be tested into the testing space 101 and laying the flame-retardant fabric 900 to be tested flat on the heating plate 11.

[0052] Specifically, in one embodiment, the drive unit 3223 is implemented as a cylinder.

[0053] More specifically, in one embodiment, the side-pull drive member 33 includes a side-pull motor 331, a lead screw 332, and a side slider 333, wherein the side slider 333 is confined within the transverse guide rail 31, and wherein the lead screw 332 is arranged parallel to the transverse guide rail 31 and is rotatably connected to the side-pull motor 331. The side slider 333 can slide along the transverse guide rail 31 as the lead screw 332 rotates. The side-pull member 32 is mounted on the side slider 333.

[0054] Furthermore, the high-temperature resistance testing equipment for the flame-retardant fabric also includes a loading platform 40, wherein the loading platform 40 is disposed at one end of the heating plate 11 and its height is adapted to the side tension member 32.

[0055] In this way, the operator can first lay one end of the flame-retardant fabric 900 to be tested on the loading table 40, and manually feed one end of the flame-retardant fabric 900 to be tested into the clamping opening 322201 between the first clamping arm 3221 and the second clamping arm 3222, so that the flame-retardant fabric 900 to be tested can be subsequently fed into the testing space 101.

[0056] Furthermore, a support plate 41 is provided on the side of the loading platform 40 near the heating plate 11. The support plate 41 extends out of the loading platform 40 and extends between the pair of side pull arms 322 of the side pull member 322 without penetrating into the detection space 101 when the side pull arm 322 moves to the end near the loading platform 40. The width of the support plate 41 is smaller than the width of the flame-retardant fabric 900 to be tested.

[0057] It is worth mentioning that, in this way, when the heating plate 11 is driven to fit against the fixing plate 12, the support plate 41 will not interfere with the movement of the heating plate 11. Furthermore, the support plate 41 extends beyond the loading platform 40 and extends between the pair of side pull arms 322 of the side pull member 32. This allows the support plate 41 to not only form the middle of the flame-retardant fabric 900 to be tested, thus avoiding the sides, so that it can be subsequently pulled into the testing space 101 by the pair of side pull arms 322, but also to better support the flame-retardant fabric 900 to be tested, facilitating the subsequent clamping of the sides of the flame-retardant fabric 900 by the pair of side pull arms 322.

[0058] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
