[0040] Example

[0041] like Figure 6 As shown, a self-excited thermochromic flame-extinguishing cloth includes a thermochromic cloth 400, which is woven from threads 410 with thermosensitive coatings attached to the surface, and the gaps of the thermochromic cloth 400 are filled with flame-extinguishing microcapsules 420.

[0042] The working mechanism of the self-excited thermochromic flame-extinguishing cloth provided in this embodiment is as follows:

[0043] Thermochromic cloth 400 is woven from wire 410 with thermosensitive coating attached to the surface. Wire 410 is flame-retardant fiber such as glass fiber, Nomex fiber or polybenzimidazole fiber. The thermosensitive coating changes color with the change of temperature, prompts the temperature of the cable, and promptly responds to whether the cable has a fault. The thermosensitive coating is made of green, yellow, red and reddish brown thermochromic powder. It is green below 40°C, yellow between 40 and 80°C, and yellow between 80 and 100°C. It is red in color, and reddish brown when the temperature is greater than 100°C. Flame-extinguishing microcapsules 420 are arranged in the gaps of the thermochromic cloth 400. The flame-extinguishing microcapsules 420 include a capsule shell and a fire extinguishing agent wrapped in the capsule shell. The fire extinguishing agent is perfluorohexanone or heptafluoropropane or IG541 or aerosol. The capsule shell is made of polymer material, and its thermal rupture temperature is 100-130°C. When the position wrapped by the flame-extinguishing cloth reaches the capsule shell rupture temperature, the capsule shell ruptures, and the fire extinguishing agent inside the capsule shell flows out, thereby extinguishing the fire in the part wrapped by the flame-extinguishing cloth.

[0044] like Figure 1-Figure 5 As shown, a manufacturing device for a thermochromic flame-extinguishing cloth, the manufacturing device is used to manufacture a self-excited thermochromic flame-extinguishing cloth, including a conveying mechanism 100, the conveying mechanism 100 includes a workbench 110, and the workbench 110 is symmetrically provided with a first roller 131 and a second roller 141; the thermochromic cloth 400 is transmitted between the first roller 131 and the second roller 141.

[0045] The working mechanism of the manufacturing equipment provided in this embodiment is as follows:

[0046] The setting of the conveying mechanism 100 enables the thermochromic cloth 400 to be transferred. The two ends of the thermochromic cloth 400 are respectively wound around the first roller 131 and the second roller 141. The first roller 131 and the second roller 141 rotate synchronously and in the same direction, so that the thermochromic cloth 400 on the first roller 131 and the second roller 141 is continuously transferred. When the thermochromic cloth 400 is in the process of continuous transfer, the flame-extinguishing microcapsules 420 can be filled into the part of the thermochromic cloth 400 between the first roller 131 and the second roller 141.

[0047] Regarding the structure of the blanking mechanism 200, specifically:

[0048] The unloading mechanism 200 includes a hopper 210, and the flame-extinguishing microcapsules 420 are placed in the hopper 210; the lower part of the hopper 210 is connected to a unloading pipe 220, and the flame-extinguishing microcapsules 420 released by the unloading pipe 220 are dropped onto the thermochromic cloth 400 driven between the first roller 131 and the second roller 141, so that the flame-extinguishing microcapsules 420 are filled in the gaps of the thermochromic cloth 400.

[0049] The flame extinguishing microcapsules 420 are placed in the hopper 210 , and the flame extinguishing microcapsules 420 can fall due to gravity. The fallen flame extinguishing microcapsules 420 can fall through the discharge pipe 220 , and the flame extinguishing microcapsules 420 dropped in the discharge pipe 220 can be dropped onto the thermochromic cloth 400 , and part of the flame extinguishing microcapsules 420 can fall and fill in the gaps of the thermochromic cloth 400 .

[0050] Regarding how to deliver the flame extinguishing microcapsule 420, specifically:

[0051] The lower part of the feed pipe 220 is connected to the feed pipe 230, and the feed pipe 220 is perpendicular to the feed pipe 230; a rotating shaft 232 is fixedly rotated in the feed pipe 230, and a spiral piece 233 is connected to the side wall of the rotating shaft 232. When the spiral piece 233 rotates, it can transport the flame-extinguishing microcapsules 420 that fall into the feed pipe 230.

[0052] The flame-extinguishing microcapsules 420 that fall into the feed tube 220 can enter the feed tube 230. Since the feed tube 220 is vertically arranged and the feed tube 230 is perpendicular to the feed tube 220, the sliding speed of the flame-extinguishing microcapsules 420 that fall into the feed tube 230 is reduced due to the influence of gravity. When the rotating shaft 232 rotates, the spiral piece 233 rotates synchronously. At this time, the rotating spiral piece 233 can transfer the flame-extinguishing microcapsules 420 in the feed tube 230. By controlling the rotation speed of the rotating shaft 232, the conveying speed of the flame-extinguishing microcapsules 420 in the feed tube 230 can be controlled, thereby avoiding too many or too few flame-extinguishing microcapsules 420 falling on the thermochromic cloth 400.

[0053] Among the optional methods of this embodiment, the more preferred ones are:

[0054] A first motor 231 is connected to the workbench 110 , and the rotating shaft 232 is fixedly connected to an output end of the first motor 231 .

[0055] When the first motor 231 is started, it can drive the rotating shaft 232 to rotate, so that the flame-extinguishing microcapsules 420 in the feeding tube 230 can be transferred. The first motor 231 adopts a servo motor and cooperates with a transmission, so that the rotation speed of the rotating shaft 232 is controllable.

[0056] Regarding how to apply force to the flame extinguishing microcapsule 420 so that it is embedded in the gap of the thermochromic cloth 400, specifically:

[0057] The end of the material transfer tube 230 is connected to a pressurizing tube 240, which is perpendicular to the surface of the thermochromic cloth 400 driven between the first roller 131 and the second roller 141; the top of the pressurizing tube 240 is connected to an air pipe 250, which is connected to an external air pump; when the spiral blade 233 pushes the flame-extinguishing microcapsule 420 into the pressurizing tube 240, the flame-extinguishing microcapsule 420 is accelerated by the air flow pressurization and hits the thermochromic cloth 400, and part of the flame-extinguishing microcapsule 420 is embedded in the gap of the thermochromic cloth 400.

[0058] The flame-extinguishing microcapsules 420 pushed by the spiral blade 233 can enter the pressurized tube 240. The pressurized tube 240 is connected to an external air pump through the air pipe 250. When the air pump is started, high-pressure gas is injected into the pressurized tube 240. The high-pressure gas accelerates the flame-extinguishing microcapsules 420 to blow them onto the thermochromic cloth 400, thereby filling the gaps in the thermochromic cloth 400 with the flame-extinguishing microcapsules 420. In order to ensure that the flame-extinguishing microcapsules 420 can be more easily embedded in the thermochromic cloth 400, the end of the pressurized tube 240 abuts against the thermochromic cloth 400, so that the thermochromic cloth 400 is elastically deformed by the squeezing of the pressurized tube 240, thereby enlarging the gaps in the thermochromic cloth 400, and the deformation of the part of the thermochromic cloth 400 that moves out of the pressurized tube 240 is restored, so that the flame-extinguishing microcapsules 420 can be more easily embedded in the gaps in the thermochromic cloth 400.

[0059] Regarding the structure of the dredging mechanism 300, specifically:

[0060] The unblocking mechanism 300 includes a bracket 310 connected to the hopper 210 , and a knocking block 320 is slidably connected to the bracket 310 . The knocking block 320 can knock the discharge pipe 220 , thereby unblocking the flame-extinguishing microcapsules 420 in the discharge pipe 220 .

[0061] When the flame extinguishing microcapsules 420 are discharged through the feed pipe 220, the knocking block 320 slides relatively on the bracket 310 to knock the feed pipe 220, causing the feed pipe 220 to vibrate, thereby clearing the flame extinguishing microcapsules 420 in the feed pipe 220 after being vibrated, preventing the feed pipe 220 from being blocked.

[0062] Among the optional methods of this embodiment, the more preferred ones are:

[0063] A guide rod 330 is connected to the bracket 310, and the guide rod 330 is slidably connected to the knocking block 320. A tension spring 340 is sleeved on the guide rod 330, and the two ends of the tension spring 340 are respectively fixedly connected to the bracket 310 and the knocking block 320; a lever 350 is connected to the rotating shaft 232, and an inclined plate 360 ​​is connected to the lower surface of the knocking block 320. When the rotating shaft 232 rotates, it can contact and push the inclined plate 360 ​​to make the knocking block 320 move away from the discharge pipe 220. When the lever 350 is separated from the inclined plate 360, the tension spring 340 is reset to make the knocking block 320 knock on the discharge pipe 220.

[0064] The knocking block 320 slides axially along the guide rod 330. When the rotating shaft 232 rotates, the lever 350 connected to the rotating shaft 232 can contact the inclined plate 360 ​​on the lower surface of the knocking block 320. When the knocking block 320 contacts the inclined plate 360 ​​and continues to move, the knocking block 320 can move along the surface of the inclined plate 360, so that the knocking block 320 is pushed and moves away from the bracket 310. At this time, the tension spring 340 is pulled and deformed to accumulate elastic potential energy. As the rotating shaft 232 continues to rotate, the lever 350 can break away from the contact with the inclined plate 360, so that the tension spring 340 is elastically released, so that the knocking block 320 quickly moves in the direction of the lower feeding pipe 220, thereby knocking the lower feeding pipe 220, so that the lower feeding pipe 220 is unblocked.

[0065] Regarding how to fully fill the gaps of the thermochromic cloth 400 with the flame-extinguishing microcapsules 420, specifically:

[0066] The conveying mechanism 100 also includes a first roller seat 130 and a second roller seat 140 symmetrically arranged on the workbench 110, and the first rotating roller 131 and the second rotating roller 141 rotate on the first roller seat 130 and the second roller seat 140 respectively; two cylinders 150 are symmetrically connected to the workbench 110, and the output ends of the two cylinders 150 are fixedly connected to the first roller seat 130 and the second roller seat 140 respectively, and the second motor 160 is connected to the second roller seat 140, and the second rotating roller 141 is fixedly connected to the output end of the second motor 160; after the two cylinders 150 are extended or shortened, the second motor 160 runs once, so that different positions of the thermochromic cloth 400 transmitted between the first rotating roller 131 and the second rotating roller 141 are alternately located at the lower port of the pressurized tube 240.

[0067] When the gap of the thermochromic cloth 400 is filled with the flame-extinguishing microcapsules 420, the first roller seat 130 and the second roller seat 140 are moved synchronously by controlling the synchronous extension and contraction of the two cylinders 150, and then the first rotating roller 131 and the second rotating roller 141 are moved synchronously, so that the thermochromic cloth 400 can move axially along the first rotating roller 131 and the second rotating roller 141, so that different parts of the thermochromic cloth 400 can move to the lower end of the pressure pipe 240 respectively, and the pressure pipe 240 is pressed against the pressure pipe 240. After stretching or shortening, the second motor 160 runs once, so that the thermochromic cloth 400 is transferred between the first roller 131 and the second roller 141. After the thermochromic cloth 400 is transferred by the first roller 131 and the second roller 141, the second motor 160 stops running after the thermochromic cloth 400 moves to a unit distance of the diameter of the pressurized tube 240. The telescopic distance of the cylinder 150 is the same as above, ensuring that the thermochromic cloth 400 can fully pass through the lower part of the pressurized tube 240.

[0068] Regarding how to clean the excess flame extinguishing microcapsules 420 on the surface of the thermochromic cloth 400, specifically:

[0069] A brush 170 is connected to the second roller seat 140 , and when the second rotating roller 141 rotates, the brush 170 can brush off the flame-extinguishing microcapsules 420 on the surface of the thermochromic cloth 400 ; a receiving tray 120 is connected to the edge of the workbench 110 , and the flame-extinguishing microcapsules 420 brushed off by the brush 170 fall into the receiving tray 120 .

[0070] When the second roller seat 140 rotates, the thermochromic cloth 400 filled with flame-extinguishing microcapsules 420 is stored on the second roller seat 140. At this time, the brush 170 connected to the second roller seat 140 can clean the surface of the thermochromic cloth 400, so that excess flame-extinguishing microcapsules 420 on the surface of the thermochromic cloth 400 are cleaned and fall off. The fallen flame-extinguishing microcapsules 420 are received by the receiving tray 120, so that the flame-extinguishing microcapsules 420 are recovered.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of each embodiment of the utility model.
