Description

Technical Field

[0001] The present application relates to the field of plastic sample testing, and in particular to a needle flame tester with a flame scale. Background Art

[0002] At present, in the fields of fiber reinforced composite materials, plastic products, polymer materials products, etc., after the products have been developed and trial-produced, before they are officially put into mass production, they often need to undergo selective tensile testing, compression testing, bending testing, fatigue testing, flame retardancy testing and other tests due to different product use environments.

[0003] In order to test the flame retardancy of samples of composite materials and plastic products, the samples are usually placed in a needle flame tester for testing. When testing the samples, the samples are clamped by the sample clamping assembly, the spray needle is first placed on the blowtorch and gas is introduced and the spray needle head is ignited by the igniter. After ignition, the operator places the flame ruler on the spray needle to measure the length of the flame. After the measurement is completed, the relative position of the sample clamping assembly and the spray needle is adjusted, and then the operator manually rotates the igniter to avoid it, and rotates the angle of the blowtorch to tilt the spray needle, and burns the sample through the spray needle to perform the flame retardancy test.

[0004] Regarding the above-mentioned related technologies, when detecting the flame length, the operator needs to manually place the flame ruler on the ignited spray needle. Since the operator holds the flame ruler for measurement, he may be burned by the flame at the spray needle, and the flame ruler is small in size and easy to lose. Utility Model Content

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0032] The embodiment of the present application discloses a needle flame tester with a flame scale 242 .

[0033] Reference Figure 1 and Figure 2A needle flame tester with a flame scale 242 comprises a box body 1, wherein the box body 1 is provided with a sample clamping assembly 3 for clamping a sample and adjusting the position of the sample, wherein a moving assembly 2 is provided in the box body 1, wherein the moving assembly 2 is provided with a mounting seat 21, wherein the moving assembly 2 is used to adjust the position of the mounting seat 21, wherein the mounting seat 21 is rotatably connected with a blowtorch base 22 for mounting a spray needle 232, wherein the blowtorch base 22 is provided with a blowtorch assembly 23, wherein an igniter 241 base 24 is provided at one side of the blowtorch base 22, wherein the igniter 241 base 24 is provided with a connecting hole, wherein the inner wall of the connecting hole is rotatably connected with the igniter 241, and the igniter 241 is detachably connected with the flame scale 242. When detecting the flame height, the operator rotates the igniter 241 to above the blowtorch assembly 23, ignites the blowtorch assembly 23 through the igniter 241, and then rotates the flame ruler 242 to the blowtorch assembly 23 by rotating the igniter 241 to measure the flame length. Since the flame ruler 242 is installed on the igniter 241, the use and storage of the flame ruler 242 is effectively simplified.

[0034] Reference Figure 2 and Figure 3 In order to realize the detachable connection between the flame scale 242 and the igniter 241, a mounting member 243 is installed on the igniter 241. In this example, the mounting member 243 includes a mounting ring and a fixing rod. One end of the fixing rod is fixedly connected to the mounting ring. An opening is provided on the side of the mounting ring away from the fixing rod. The mounting ring is clamped with the igniter 241. A clamping groove is provided on the side of the fixing rod away from the igniter 241. The clamping groove is adapted to the flame scale 242. The igniter 241 and the flame scale 242 are installed through the mounting member 243. The operator installs the flame scale 242 on the fixing rod through the clamping groove, and then fixes the mounting member 243 to the igniter 241 through the opening on the mounting ring. Since the connection between the mounting ring and the igniter 241 is clamped, and the flame scale 242 and the fixing rod are also clamped, it is convenient to disassemble the mounting member 243.

[0035] Reference Figure 3 In order to facilitate the production of the connecting rod, the fixing rod and the mounting ring are integrally formed. Since the fixing rod and the mounting ring are integrally formed, the manufacturing method of the mounting member 243 is effectively simplified during processing and manufacturing, and the connection method between the mounting ring and the fixing rod is simplified.

[0036] Reference Figure 3During use, the angle of the flame needs to be adjusted to ignite different parts of the sample. In the existing technology, the operator is usually required to manually adjust the angle and confirm the adjusted angle through the corresponding dial. In order to replace the operator to adjust the angle of the blowtorch assembly 23. A second servo motor 26 is provided on the side of the mounting seat 21 away from the blowtorch base 22. The motor shaft of the second servo motor 26 is connected to the mounting seat 21. When the second servo motor 26 rotates, the mounting seat 21 rotates with the second servo motor 26. When the mounting seat 21 rotates, the mounting seat 21 is driven to rotate by the second servo motor 26. By controlling the rotation angle of the second servo motor 26, the motor replaces the operator to rotate the mounting seat 21, and the rotation angle of the mounting seat 21 is effectively adjusted. At the same time, there is no need for the operator to operate close to the ignited blowtorch.

[0037] Reference Figure 2 and Figure 3 , in order to achieve avoidance after the igniter 241 has ignited. The base 24 of the igniter 241 is provided with a first servo motor 25, the first servo motor 25 is provided with a first gear 251, and the igniter 241 is provided with a second gear 252. The first gear 251 and the second gear 252 are kept in meshing. When the first servo motor 25 rotates, the igniter 241 rotates in the base 24 of the igniter 241. When the igniter 241 needs to be rotated, the first gear 251 is driven to rotate by the rotation of the first servo motor 25, and the second gear 252 is driven to rotate by the first gear 251, and the igniter 241 is driven to rotate by the second gear 252. Since the rotation angle of the servo motor is controllable, the rotation angle of the igniter 241 is precisely controlled, and the igniter 241 is effectively rotated by the motor instead of the operator.

[0038] Reference Figure 2 and Figure 3 , in order to reduce the displacement of the igniter 241 in the vertical direction during use. The igniter 241 is provided with a limiting ring 244, the diameter of which is larger than the diameter of the connecting hole. When in normal use, the lower end face of the limiting ring 244 is in contact with the upper end face of the base 24 of the igniter 241. When the igniter 241 is in normal use, the lower end face of the limiting ring 244 is in contact with the upper end face of the base 24 of the igniter 241, and the limiting ring 244 is in contact with the upper end face of the igniter 241 during the entire installation and use process, so as to effectively limit the igniter 241.

[0039] Reference Figure 3After long-term use, the blowtorch assembly 23 needs to be replaced. In order to facilitate the maintenance and replacement of the blowtorch assembly 23, the blowtorch assembly 23 includes a blowtorch socket 231 and a spray needle 232. The blowtorch socket 231 is detachably connected to the blowtorch base 22, and the blowtorch socket 231 is provided with a slot adapted to the spray needle 232. When installing the blowtorch assembly 23, the pin is installed to the blowtorch socket 231 through the slot, which simplifies the installation difficulty of the blowtorch assembly 23. When replacing the spray needle 232, it is only necessary to pull the spray needle 232 out of the blowtorch socket 231 and insert a new spray needle 232 into the blowtorch socket 231 to complete the replacement of the spray needle 232, which simplifies the replacement and installation of the blowtorch assembly 23.

[0040] Reference Figure 2 and Figure 4 In actual use, the blowtorch assembly 23 and the sample clamping assembly 3 for clamping the sample need to be adjusted. In this example, the sample clamping assembly 3 includes a clamp base 34, a horizontal slide rail 31 and a vertical slide rail 32. The horizontal slide rail 31 is fixedly connected to the inner wall of the box body 1. The horizontal slide rail 31 includes an upper slide rail and a lower slide rail. The upper slide rail and the lower slide rail are both slidably connected with a slider 33. The vertical slide rail 32 is located between the two sliders 33. The clamp base 34 is slidably connected to the vertical slide rail 32. A lead screw 35 is rotatably connected between the two sliders 33. The clamp base 34 is provided with a threaded hole adapted to the lead screw 35. The slider 33 is provided with a driving motor for driving the lead screw 35 to rotate. The clamp base 34 is provided with a clamping jaw 37. The clamp base 34 is provided with a driving assembly 36 for driving the clamping jaw 37 to move horizontally. The operator manually adjusts the position of the slider 33 on the upper slide rail and the lower slide rail, thereby adjusting the position on the clamp base 34, and then drives the lead screw 35 to rotate through the drive motor to adjust the clamp base 34 in the vertical direction, and then adjusts the position of the clamp 37 installed on the clamp base 34 through the drive assembly 36, thereby effectively adjusting the position of the clamp 37.

[0041] The implementation principle of a needle flame tester with a flame ruler 242 in an embodiment of the present application is as follows: the flame ruler 242 is installed on the igniter 241 through the mounting member 243, and the igniter 241 and the flame ruler 242 are controlled by the first servo motor 25 to approach and move away from the blowtorch assembly 23, thereby achieving avoidance of the igniter 241 and the flame ruler 242, and the rotation of the mounting base 21 is controlled by the second servo motor 26, thereby achieving control of the angle of the blowtorch assembly 23.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
