Technical Field

[0001] The invention relates to the technical field of cloth production, in particular to a detection device for flame-resistant textile cloth. Background Art

[0002] Flame-retardant fabric is a flame-retardant composite material with high temperature resistance, low thermal conductivity, thermal shock resistance, and low heat capacity. When selecting and using refractory fiber fabric, its temperature resistance level, physical size, chemical stability, and expected application environment should be considered. For environments that need to withstand high temperatures or chemical reactions for a long time, refractory fiber fabrics of corresponding grades and treatments should be selected. At the same time, understanding the characteristics of different coatings is also the key to ensuring safety and efficiency.

[0003] In order to obtain flame-resistant textile fabrics that meet production requirements, special equipment is usually required to test the flame-resistant textile fabrics. For example, in the patent document with application number: 202222239497.5, a flame-resistant testing device for base fabric is disclosed, and a flame spray test is performed after the fabric is clamped. In this process, the flame spray test is point-like flame spraying, and the flame-resistant performance of the fixed position of the fabric is tested.

[0004] In the patent document with application number 202220252203.X, a fabric combustion tester is disclosed, and it is specifically disclosed that by setting a collection box, the substances generated by the combustion of the fabric fall into the collection box, thereby realizing the collection of waste.

[0005] In the above technical scheme, the detection of point-shaped fixed flame spraying can only control the textile fabric in a corresponding small area directly contacting the fire source end, so the detection range is relatively limited; at the same time, when the fire source end performs an ignition test on the range, the range is heated by the fire source end, but usually when the flame resistant fabric is in an environment where a fire source exists, the temperature of the environment in which the flame resistant fabric is located should be increased as a whole to simulate the combustion environment, and there is no step for simulating this state in the prior art, resulting in inaccurate detection, thereby affecting the accuracy of the flame retardancy detection of the flame resistant fabric. Summary of the invention

[0006] The object of the present invention is to provide a detection device for flame retardant textile fabrics.

[0007] The technical problem solved by the present invention is to solve the problem in the prior art that the textile fabric is fixed during the flame retardancy test and the fire source is point-shaped, which affects the detection accuracy of the textile fabric.

[0008] The present invention can be implemented through the following technical scheme: a flame retardant textile fabric detection device, comprising a detection box for performing flame retardant detection on textile fabrics, the detection box is provided with an inlet and outlet slot for realizing the inlet and outlet of textile fabrics, a guiding mechanism for guiding the textile fabrics is arranged inside the detection box, and a heating mechanism for heating the textile fabrics is arranged on the guiding mechanism.

[0009] A further technical improvement of the present invention is that the guiding mechanism comprises a top guiding roller and a bottom guiding roller, and the top guiding roller and the bottom guiding roller are rotatably mounted on the detection box body respectively.

[0013] A further technical improvement of the present invention is that a gas guide tube is coiled on the top of the detection box, and the input end of the gas guide tube is connected to the inside of the detection box.

[0014] A further technical improvement of the present invention is that a rotating shaft is arranged inside the detection box, a rotating base is symmetrically mounted on the rotating shaft, and an ignition end for forming a point-shaped ignition source and an ignition carbon layer for forming a strip-shaped ignition source are respectively mounted on the rotating base.

[0015] A further technical improvement of the present invention is that a fire extinguishing shell for extinguishing the ignition carbon layer and an ignition shell for igniting the ignition carbon layer are also fixed inside the detection box.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present application provides an inlet and outlet slot for realizing the inlet and outlet of textile fabrics on the detection box, and at the same time, a guiding mechanism for guiding the textile fabric is provided in the detection box, so that the textile fabric first passes through the inlet and outlet slot into the interior of the detection box, and the guiding mechanism is used to guide the textile fabric until the textile fabric is guided out of the detection box. At this time, the textile fabric is dynamic. When the fire source of the flame retardancy test is point-shaped, a continuous linear ignition area will be formed on the textile fabric, expanding the point-shaped ignition area in the original technology, ensuring that the same textile fabric has a larger ignition area, thereby ensuring that the detection accuracy of the textile fabric is relatively accurate. At the same time, a heating mechanism for heating the textile fabric is provided on the guiding mechanism, so that the textile fabric is heated under the action of the heating mechanism to simulate the temperature during combustion, that is, to judge the influence of temperature on the flame retardancy of the textile fabric, and further obtain a more accurate textile fabric detection result.

[0018] 2. The present application adopts the combination of an intermediate heating roller and a matching heating roller, so that the intermediate heating roller can be used to preliminarily heat the textile fabric.

DETAILED DESCRIPTION

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0030] See also Figure 1-6As shown, the flame retardant textile fabric detection device comprises a detection box 5 for detecting a textile fabric 1, an ignition mechanism 4 for directly performing flame retardant detection on the textile fabric 1 is arranged inside the detection box 5, and a guide mechanism 3 for guiding the textile fabric 1 is also arranged inside the detection box 5, and a heating mechanism 2 for heating the textile fabric 1 is arranged on the guide mechanism 3. When in use, the textile fabric 1 is first guided by the guide mechanism 3 so that the textile fabric 1 can automatically enter the interior of the detection box 5, and the textile fabric 1 is heated by the heating mechanism 2 to simulate the temperature of the textile fabric 1 in an external combustion environment, and to judge the influence of the temperature on the flame retardant performance of the textile fabric 1, and a top exhaust mechanism 6 is arranged on the top of the detection box 5 to recover the exhaust gas obtained by burning air inside the detection box 5, and the recovered gas acts on the outer surface of the detection box 5 to keep the detection box 5 warm.

[0031] First, an inlet and outlet slot 51 for enabling the textile fabric 1 to enter and exit is opened on the detection box 5, and a hinged cabinet door 52 is hingedly arranged on the side of the detection box 5, wherein the hinged cabinet door 52 is provided with an observation glass window 53, which is used for real-time viewing of the detection process through the observation glass window 53 during the flame retardancy test. At the same time, the hinged cabinet door 52 can clean, install and repair the interior of the detection box 5.

[0032] As a further embodiment of the present application, the guiding mechanism 3 includes a top guiding roller 31 and a bottom guiding roller 32, wherein the top guiding roller 31 and the bottom guiding roller 32 are respectively fixedly mounted on the inlet and outlet slot 51, and the height of the top guiding roller 31 is higher than that of the bottom guiding roller 32, and the textile fabric 1 enters from the bottom inlet and outlet slot 51, and is initially guided by the bottom guiding roller 32, and then the textile fabric 1 is guided by the top guiding roller 31, so that the textile fabric 1 passes through the top inlet and outlet slot 51. During this process, the textile fabric 1 is in a planar state between the top guiding roller 31 and the bottom guiding roller 32, so that the textile fabric 1 is opened, which is convenient for the ignition mechanism 4 to perform ignition detection operation on it. At the same time, in the present application, by utilizing the top guiding roller 31 and the bottom guiding roller 32 replaces the original clamping device, so that the fluidity test of the textile fabric 1 can be carried out, that is, the original fixed test is replaced by the fluidity test, and a dynamic result of a continuous flame retardancy test is obtained on the textile fabric 1, so that multiple sets of data can be obtained through a set of experiments, avoiding the need to frequently open the hinged cabinet door 52 and the waste of efficiency in replacing the test items; and in the present application, the textile fabric 1 enters from the bottom guide roller 32, and then passes between the bottom guide roller 32 and the top guide roller 31 for the flame retardancy test. After the test, the textile fabric 1 can be placed horizontally under the action of the top guide roller 31. At this time, the flame retardancy test obtains that part of the adhesion will adhere to the top of the textile fabric 1, which is convenient for position matching of impurities in various parts, so that more accurate flame retardancy can be obtained.

[0033] The heating mechanism 2 includes an intermediate heating roller 21, wherein the intermediate heating roller 21 is fixedly installed inside the detection box 5, and the intermediate heating roller 21 is located between the top guide roller 31 and the bottom guide roller 32. A matching heating roller 23 is installed at the bottom of the detection box 5. The height and lateral position of the matching heating roller 23 are adjustable, and it is used to cooperate with the intermediate heating roller 21. Therefore, before the textile fabric 1 is tested for flame retardancy, the textile fabric 1 is first contacted with the intermediate heating roller 21, and the intermediate heating roller 21 is used to heat it. Then, the height and lateral position of the matching heating roller 23 are adjusted so that the matching heating roller 23 can be clamped on the intermediate heating roller 21. The intermediate heating roller 21 and the matching heating roller 23 work together to achieve sufficient heating treatment of the textile fabric 1, so that the obtained textile fabric 1 is at a simulated temperature. When the textile fabric 1 is at a certain temperature, the flame retardancy is tested, so that a more accurate flame retardancy value can be obtained.

[0034] In order to adjust the height and lateral position of the mating heating roller 23, in the present application, the mating heating roller 23 is rotatably installed on a limit base, a limit ball 28 is fixed on the side of the limit base, and a side sliding seat 26 is fixed on the bottom of the detection box 5, wherein the side sliding seat 26 is provided with an arc groove 27 for cooperating with the limit ball 28. When in use, the limit base is pushed upward so that the limit ball 28 on the side of the limit base moves inside the arc groove 27, thereby controlling the position of the mating heating roller 23, so that the mating heating roller 23 and the intermediate heating roller 21 are coordinated.

[0035] A bottom telescopic rod 24 is fixed at the bottom of the detection box 5, and a bottom connecting rod 22 is fixed at the end of the bottom telescopic rod 24, wherein the bottom connecting rod 22 is slidably connected to the bottom sliding seat 25, and the bottom sliding seat 25 is fixedly connected to the limiting base. When in use, the bottom telescopic rod 24 is started to push the bottom connecting rod 22 upward, so as to control the longitudinal height of the mating heating roller 23, and then the bottom sliding seat 25 at the bottom of the mating heating roller 23 is slidably connected to the output end of the bottom telescopic rod 24, so that the mating heating roller 23 can cooperate with the arc groove 27 to move in an arc shape, so that the mating heating roller 23 can move both laterally and longitudinally, so as to cooperate with the middle heating roller 21.

[0036] As a further embodiment of the present application, the top exhaust mechanism 6 includes a gas guide pipe 61, wherein the gas guide pipe 61 is used to collect the gas exhausted from the detection box 5, and the gas guide pipe 61 is coiled on the outside of the detection box 5, and the gas heat in the gas guide pipe 61 is conducted to the outer surface of the detection box 5 by heat conduction, thereby achieving the thermal insulation performance of the detection box 5, reducing heat loss, and realizing the simulation of the combustion environment.

[0037] The ignition mechanism 4 includes a rotating shaft 49, and a power chassis is installed inside the detection box 5. The rotating shaft 49 is driven to rotate by the power chassis. The power chassis includes a power motor and a transmission assembly for providing power. The transmission assembly is driven by the power motor and finally drives the rotating shaft 49. A fire extinguishing shell 41 and an ignition shell 44 are also fixed inside the detection box 5, wherein the fire extinguishing shell 41 and the ignition shell 44 are respectively matched with the ignition assembly, wherein the ignition assembly is installed at the output end of the rotating shaft 49, and the position of the ignition assembly is controlled by the rotation of the rotating shaft 49. When the ignition assembly is located inside the fire extinguishing shell 41, the fire source on the ignition assembly is extinguished, and when the ignition assembly is located inside the ignition shell 44, the ignition assembly is ignited, so that the corresponding ignition method can be selected according to needs.

[0038] Specifically, the ignition component of the present application includes an ignition end 47 and an ignition carbon layer 43, wherein the ignition end 47 and the ignition carbon layer 43 are symmetrically arranged at both ends of the rotating shaft 49, and the ignition end 47 sprays out a point-shaped fire source, which has a certain range, but its range is small, and the ignition carbon layer 43 is in the shape of a long strip. When the ignition carbon layer 43 is ignited, its fire source is in the shape of a long strip. The disadvantage is that the fire source spraying position is not as precise as that of the ignition end 47. Therefore, in the present application, the corresponding fire source mode can be selected as needed. When the textile fabric 1 moves, the ignition end 47 is continuously ignited, and a narrower flame retardant test area will be presented on the textile fabric 1, and the farther away from the ignition end 47, the worse the flame retardant test effect; if the ignition carbon layer 43 is used for ignition, a relatively uniform rectangular test area will be presented on the textile fabric 1, and the entire textile fabric 1 will be exposed to the fire source.

[0039] The rotating bases 42 are symmetrically fixed on both sides of the rotating shaft 49, and the ignition carbon layer 43 and the ignition end 47 are fixedly installed on each rotating base 42. When the rotating shaft 49 rotates, the ignition carbon layer 43 enters the first cavity 411 of the fire extinguishing shell 41. At this time, the oxygen in the first cavity 411 is gradually consumed, and the ignition carbon layer 43 is gradually extinguished. When the ignition carbon layer 43 enters the second cavity 46 of the ignition shell 44, the ignition carbon layer 43 is ignited by the ignition device inside the ignition shell 44, and after ignition, it faces the textile fabric 1 to test the flame retardancy of the textile fabric 1.

[0040] As a further embodiment of the present application, a fireproof shell 410 is installed on the rotating base 42 corresponding to the ignition end 47. The fireproof shell 410 acts around the ignition end 47 to form a point-shaped ejection port at the ignition end 47 for detecting the textile fabric 1 under a specific state.

[0041] When the present invention is used, the textile fabric 1 enters from the bottom feed-in and feed-out slot 51, is initially guided by the bottom guide roller 32, and then is guided by the top guide roller 31, so that the textile fabric 1 passes through the top feed-in and feed-out slot 51. During this process, the textile fabric 1 is in a planar state between the top guide roller 31 and the bottom guide roller 32, so that the textile fabric 1 is stretched;

[0042] Then the textile fabric 1 contacts the middle heating roller 21 and is heated by the middle heating roller 21. Then the height and lateral position of the matching heating roller 23 are adjusted, that is, the bottom telescopic rod 24 is started to push the bottom connecting rod 22 upward, so that the longitudinal height of the matching heating roller 23 can be controlled. Then the bottom sliding seat 25 at the bottom of the matching heating roller 23 and the output end of the bottom telescopic rod 24 are slidably connected to realize that the matching heating roller 23 can cooperate with the arc groove 27 to move in an arc shape, so that the matching heating roller 23 can move both laterally and longitudinally, and can cooperate with the middle heating roller 21. The matching heating roller 23 can be clamped on the middle heating roller 21. The middle heating roller 21 and the matching heating roller 23 work together to achieve sufficient heating treatment of the textile fabric 1, so that the obtained textile fabric 1 is at a simulated temperature. When the textile fabric 1 is at a certain temperature, the flame retardancy test is performed on it.

[0043] The corresponding flame retardancy test method is selected according to the needs, that is, the flame retardancy test is performed using the ignition end 47 or the ignition carbon layer 43. When the flame retardancy test is performed using the ignition end 47, the ignition end 47 is driven by the rotation of the rotating shaft 49 so that the ignition end 47 faces the textile fabric 1. At this time, when the textile fabric 1 is moving, a narrow flame retardancy test area will be formed on the textile fabric 1, and the farther away from the ignition end 47, the worse the flame retardancy test effect; if the ignition carbon layer 43 is used, the ignition carbon layer 43 is driven by the rotation of the rotating shaft 49. 43 is located inside the ignition housing 44, the ignition carbon layer 43 is ignited, and then the rotating shaft 49 continues to rotate, so that the ignition carbon layer 43 is rotated to the textile fabric 1, and the ignition carbon layer 43 is used for ignition, and a relatively uniform rectangular test area will be presented on the textile fabric 1, and its detection range is large, but the concentration of the fire source is not as good as the direct combustion test of the ignition end 47. After the test is completed, the ignition carbon layer 43 is rotated to the inside of the first cavity 411, and the oxygen inside the first cavity 411 is gradually consumed, and the ignition carbon layer 43 is gradually extinguished;

[0044] During the above operation process, the textile fabric 1 can be continuously loaded and continuously subjected to flame retardant performance tests, and several performance test results can be obtained on a textile fabric 1, such as flame retardant performance tests at different temperatures, flame retardant performance tests at different fire sources, and other results.

[0045] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
