Technical Field

[0001] This invention relates to the field of protective material testing equipment. More specifically, this invention relates to a protective material contact heat testing device. Background Technology

[0002] Thermal protective fabrics are characterized by their ability to shield and reflect heat from high-temperature heat sources, maintaining a lower temperature on the back side and thus protecting the human body or other objects from harm. Therefore, they are special fabrics that are heat-resistant, heat-insulating, and block heat transmission. They have broad prospects in the manufacture of protective clothing, building materials, aerospace materials, and military materials. However, during the preparation of protective materials, it is necessary to test the contact heat of the material. Existing testing devices cannot be adjusted based on the thickness of the protective material during use, affecting the accuracy of the test results. Summary of the Invention

[0004] Another objective of this invention is to provide a protective material contact heat detection device, which, by setting up a lifting rod and a limiting plate, enables the adjustment of the height of the stage based on the thickness of the sample to be tested, and limits the stage by using the limiting plate.

[0005] To achieve these objectives and other advantages of the present invention, a protective material contact heat detection device is provided, comprising: The base has a heating element and a rotatable disc, on which multiple horizontal bars are spaced apart along the outer circumference of the disc. Multiple loading mechanisms are provided, with each loading mechanism corresponding to a horizontal bar. Each loading mechanism includes a lifting rod on the horizontal bar and a pair of support blocks on the horizontal bar. The lifting rod is located between the two support blocks. A loading platform is connected to the top of the lifting rod to hold the sample to be tested. A limiting plate is detachably connected to both support blocks. During testing, the upper surface of the sample to be tested contacts the lower surface of the limiting plate. The limiting plate has an opening, and the opening has two openable and closable covers. When the two covers close the opening, the lower surface of the covers is flush with the lower surface of the limiting plate.

[0006] Preferably, the top of the support block is recessed downward to form a U-shaped fixing groove, the side wall of the fixing groove is provided with a pair of first positioning holes, and each end of the limiting plate is provided with a second positioning hole. The two second positioning holes correspond one-to-one with the pair of first positioning holes and are connected by a pin to facilitate the placement of the sample to be tested.

[0007] Preferably, the support block is provided with a fixing plate on both sides of the fixing groove, and a rotatable shaft is provided between the two fixing plates. The two covers are respectively connected to the two shafts. An adjustment plate is provided on the shaft, and the included angle between the adjustment plate and its corresponding cover is 90°. It also includes: an opening and closing mechanism, which includes a support frame on the base, two first rotary motors on the support frame, the two first rotary motors being arranged one-to-one with two adjusting plates, a drive rod connected to the end of the output shaft of the first rotary motor, and a drive plate on the drive rod. When the drive plate rotates to contact the adjusting plate and continues to rotate, the drive plate drives the adjusting plate to change from a vertical state to a horizontal state. The adjustment plate is provided with a plurality of first magnets at intervals on the surface away from the cover, and the top of the support block is provided with a plurality of second magnets at intervals. The second magnets are arranged in a one-to-one correspondence with the first magnets and the second magnets are magnetically attracted to the first magnets. When the adjustment plate changes from a vertical state to a horizontal state, the adjustment plate is in contact with the top of the support block.

[0008] Preferably, the lifting rod includes a first rod body connected to the horizontal rod and a second rod body connected to the platform. Both the first rod body and the second rod body have external threads. The first rod body and the second rod body are connected by a nut to adjust the distance between the first rod body and the second rod body.

[0009] Preferably, the base is provided with a second rotary motor, and the output shaft of the second rotary motor is connected to the disk.

[0010] Preferably, the base is provided with an annular first slide rail, the first slide rail is coaxially arranged with the disc, and the horizontal bar is provided with a first slider, the first slider being slidably connected to the first slide rail.

[0011] Preferably, the heating assembly includes a first bracket on the base, a horizontal support rod slidably mounted on the first bracket, and a fixing block on the support rod.

[0012] The present invention has at least the following beneficial effects: First, this invention achieves adjustable stage height based on the thickness of the sample by setting up a lifting rod and a limiting plate, with the limiting plate providing a limit. By setting up multiple loading mechanisms, one mechanism places the sample, another performs the testing, and the rest cools. This setup effectively improves testing efficiency. Furthermore, cooling the loading mechanisms before removal effectively prevents accidental injury to the user due to high temperatures. The invention also features an opening and a cover on the limiting plate. After the sample is placed on the stage, rotating the disc moves the stage below the heating assembly, and opening the cover allows for heating. This setup limits the stage height (based on the thickness of the protective material) through the limiting plate, and the cover not only facilitates heating but also secures the sample, preventing movement during stage rotation.

[0013] Secondly, the present invention can avoid close proximity to the heating component by setting an opening and closing mechanism, thereby reducing the harm to the user caused by high temperature; the cover can be opened by setting a drive plate, a drive rod, and an adjustment plate to facilitate testing; the adjustment plate can be fixed by setting a first magnet and a second magnet, thereby fixing the cover.

[0014] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0017] like Figure 1-7 As shown, the present invention provides a protective material contact heat detection device, comprising: The base 1 is equipped with a heating component and a rotatable disc 2. Multiple horizontal bars 20 are spaced apart along the outer circumference of the disc 2. Multiple loading mechanisms are provided, each corresponding to a horizontal bar 20. Each loading mechanism includes a lifting rod on the horizontal bar 20 and a pair of support blocks 3 on the horizontal bar 20. The lifting rod is located between the two support blocks 3. The top of the lifting rod is connected to a loading platform 23 to hold the sample to be tested. A limiting plate 4 is detachably connected to both support blocks 3. During testing, the upper surface of the sample to be tested contacts the lower surface of the limiting plate 4. The limiting plate 4 has an opening, and the opening has two openable and closable covers 11. When the two covers 11 close the opening, the lower surface of the cover 11 is flush with the lower surface of the limiting plate 4, and one of the loading mechanisms is located below the heating component.

[0018] In this technical solution, the heating component is used to heat the sample to be tested. The central axis of the disc 2 is vertically set, the horizontal rod 20 is horizontally set, and the lifting rod is vertically set. The sample to be tested is placed on the stage 23. By adjusting the height of the lifting rod, the stage 23 is moved upward until the upper surface of the sample to be tested contacts the lower surface of the limiting plate 4. (Whether the upper surface of the sample to be tested contacts the lower surface of the limiting plate 4 can be determined by visual observation by the user or by installing a pressure sensor, controller, and alarm on the stage 23. When the pressure sensor senses that the limiting plate 4 is pressing against the stage, the pressure sensor will activate the alarm.) The force sensor transmits the sensed pressure signal to the controller, which causes the alarm to sound. The number of the loading mechanism is three or four. Under the action of the rotating disc 2, when one of the loading platforms 23 is placing a sample, the loading platform 23 adjacent to it is located below the heating component for detection. The sample to be tested on the remaining loading platforms 23 is cooled down. After cooling is completed, the sample to be tested is separated from the loading platform 23. One of the detachable connection methods between the support block 3 and the limiting plate 4 can be the screw connection. The design of the loading platform 23 adopts the existing technology. The limiting plate 4 is set horizontally.

[0019] During use, along the rotation direction of disk 2, one loading mechanism places the sample to be tested, another loading mechanism performs testing below the heating element, and the remaining loading mechanism cools down (after cooling, the sample to be tested is separated from the loading platform 23). For the loading mechanism placing the sample to be tested: first, the sample to be tested is placed on the loading platform 23, then the limiting plate 4 is connected to the support block 3, and then the height of the loading platform 23 is adjusted by the lifting rod until the upper surface of the sample to be tested contacts the lower surface of the limiting plate 4 and the lower surface of the cover 11, thus completing the placement of the sample to be tested; after the loading mechanism located below the heating element completes its testing, disk 2 is rotated to move the loading mechanism away from the heating element after testing. The components are cooled. At the same time, the loading mechanism with the sample to be tested placed is rotated to the bottom of the heating component and the cover 11 is opened for testing. For the loading mechanism after cooling: first close the cover 11, then separate the limiting plate 4 from the support block 3, and take out the sample to be tested. If the same protective material needs to be placed, then place the sample to be tested directly on the loading stage 23 and connect the limiting plate 4 to the support block 3. If a new sample of a different thickness is used, then first adjust the lifting rod to lower the loading stage 23 to the lowest position, place the new sample to be tested on the loading stage 23, then connect the limiting plate 4 to the support block 3, and finally adjust the height of the loading stage 23 by lifting the lifting rod.

[0020] By adopting this technical solution, the present invention achieves height adjustment of the stage 23 based on the thickness of the sample to be tested by setting a lifting rod and a limiting plate 4, and limits the position of the stage 23 by the limiting plate 4. By setting multiple loading mechanisms, one loading mechanism places the sample, one loading mechanism performs the test, and the rest cools the sample. This setting can effectively improve the testing efficiency. At the same time, cooling the loading mechanism before removing it can effectively prevent the user from being injured by the high temperature of the loading mechanism. The present invention sets an opening and a cover 11 on the limiting plate 4. After the sample to be tested is placed on the stage 23, the rotating disk 2 moves the stage 23 to the bottom of the heating component, and the cover 11 is opened for heating. This setting limits the height of the stage 23 (based on the thickness of the protective material) by the limiting plate 4. On the other hand, the cover 11 not only facilitates the heating of the sample to be tested, but also fixes the sample to be tested, preventing the sample to be tested from moving during the rotation of the stage 23.

[0021] In another technical solution, the top of the support block 3 is recessed downward to form a U-shaped fixing groove 15 (the horizontal cross-section of the fixing groove 15 is U-shaped). The side wall of the fixing groove 15 is provided with a pair of first positioning holes (the two first positioning holes correspond to the two parallel side walls of the fixing groove 15 respectively). Each end of the limiting plate 4 is provided with a second positioning hole. The two second positioning holes correspond one-to-one with the pair of first positioning holes and are connected by a pin 16 to facilitate the placement of the sample to be tested. Using this technical solution, the present invention achieves a detachable connection between the limiting plate 4 and the support block 3 by setting the fixing groove 15, the first positioning holes, and the second positioning holes.

[0022] In another technical solution, the support block 3 is provided with a fixing plate 13 on both sides of the fixing groove 15, and a rotatable shaft 14 is provided between the two fixing plates 13 (the two fixing plates 13 are arranged in parallel). The two covers 11 are respectively connected to the two shafts 14 (the connecting shaft is parallel to the pin 16). An adjusting plate 9 is provided on the shaft 14. The adjusting plate 9 is arranged along the length direction of the shaft 14, and the included angle between the adjusting plate 9 and its corresponding cover 11 is 90°. It also includes an opening and closing mechanism, which includes a support frame 7 mounted on the base 1. The support frame 7 is equipped with two first rotary motors 8 (the output shafts of the first rotary motors 8 are horizontally arranged). The two first rotary motors 8 are arranged in a one-to-one correspondence with two adjusting plates 9. The output shafts of the first rotary motors 8 are connected to a drive rod 21. The drive rod 21 is equipped with a drive plate 22 (the drive plate 22 is arranged along the length direction of the drive rod 21). When the drive plate 22 rotates to contact the adjusting plate 9 and continues to rotate, the drive plate 22 drives the adjusting plate 9 to change from a vertical state to a horizontal state. The adjusting plate 9 has multiple first magnets 30 spaced apart from the surface of the cover 11, and the top of the support block 3 has multiple second magnets 12 spaced apart. The second magnets 12 correspond one-to-one with the first magnets 30, and are magnetically attracted to each other. When the adjusting plate 9 changes from a vertical to a horizontal state, it fits against the top of the support block 3. During use, when the loading mechanism moves below the heating assembly and requires heating, the first rotary motor 8 drives the drive plate 22 to rotate, which in turn drives the adjusting plate 9 to rotate 90°, opening the cover 11. This invention, by setting an opening and closing mechanism, avoids proximity to the heating assembly, reducing the risk of injury to the user from high temperatures; by setting the drive plate 22, drive rod 21, and adjusting plate 9, the cover 11 is opened for easy inspection; and by setting the first magnets 30 and second magnets 12, the adjusting plate 9 is fixed, thereby fixing the cover 11.

[0023] In another technical solution, the lifting rod includes a first rod 17 connected to the horizontal rod 20 and a second rod 18 connected to the stage 23. Both the first rod 17 and the second rod 18 have external threads. The first rod 17 and the second rod 18 are connected by a nut 19 to adjust the distance between them. Both the first rod 17 and the second rod 18 are vertically arranged. Using this technical solution, the height of the stage 23 can be adjusted by rotating the nut 19 during use, allowing for simultaneous observation of the distance between the sample to be tested and the limiting plate 4 while adjusting the height of the stage 23.

[0024] In another technical solution, a second rotary motor is provided on the base 1, and the output shaft of the second rotary motor is connected to the disk 2. Using this technical solution, the present invention drives the disk 2 to rotate by setting up a second rotary motor.

[0025] In another technical solution, the base 1 is provided with an annular first slide rail, which is coaxially arranged with the disc 2. The horizontal rod 20 is provided with a first slider, which is slidably connected to the first slide rail. Using this technical solution, the present invention, by setting the first slide rail and the first slider, can not only support the horizontal rod 20, but also enable the horizontal rod 20 to rotate.

[0026] In another technical solution, the heating assembly includes a first bracket 5 mounted on the base 1, a horizontal support rod 6 slidably mounted on the first bracket 5 (the first bracket 5 is provided with a third slide rail, the third slide rail is provided with a third slider, the third slider is connected to one end of the support rod 6 so that the support rod 6 can move up and down relative to the first bracket 5, the support frame 7 is located below the first bracket 5), and a fixing block 24 mounted on the support rod 6. The fixing block 24 is provided with two through holes, and a slidable connecting rod 25 is provided in the through holes (the diameter of the through holes is larger than the diameter of the connecting rod 25, and the height of the fixing block 24 is smaller than the length of the connecting rod 25). A gravity block 10 is provided at the top of the connecting rod 25, and a heater 27 is connected to the lower ends of the two connecting rods 25. A heating copper block 28 is provided at the lower end of the heater 27. A first telescopic motor is provided at the top of the first bracket 5, and the first telescopic motor is connected to the support rod 6. The base 1 is equipped with a support rod, and a third rotary motor is located at the top of the support rod (the output shaft of the third rotary motor is vertically arranged and perpendicular to the heat insulation plate 29). The output shaft of the third rotary motor is connected to the heat insulation plate 29 (the heat insulation plate 29 is horizontally arranged). The heat insulation plate 29 is located below the heating copper block 28 (the stage 23 is equipped with a thermocouple). During use, before testing, the heat insulation plate 29 is located below the heating copper block 28. During testing, the third rotary motor drives the heat insulation plate 29 to rotate so that the heating copper block 28 contacts the sample to be tested. During testing, the first telescopic motor drives the support rod 6 to move downward until the heating copper block 28 contacts the upper surface of the sample to be tested, and then the support rod 6 continues to move downward. At this time, the gravity block 10 squeezes the heating copper block 28, and finally the test is performed. Using this technical solution, the present invention heats the sample to be tested by setting up a heater 27, a heating copper block 28, and a support rod 6.
