The bidirectional worm 18 is meshed and arranged at the top of the corresponding two worm gears 14. Each bidirectional worm 18 drives the corresponding two worm gears 14 to rotate when rotating, thereby realizing the simultaneous rotation of the two worm gears 14 and the two bidirectional screw rods 13.

The inner wall of the slave bevel gear 22 is fixedly connected to the surface of the bidirectional worm 18. When the servo motor 20 is started, the servo motor 20 will drive the slave bevel gear 22 to rotate through the main bevel gear 21, and the slave bevel gear 22 will drive the bidirectional worm 18 to rotate, thereby driving the two bidirectional screw rods 13 at the same time. There is no need to rotate the four bidirectional screw rods 13 in sequence by hand, which saves time and effort. It should be added that the contact part of the bidirectional screw rod 13 and the connecting seat 11 is rotatably connected through a sealed bearing, and the guide groove 12 is set to be U-shaped, thereby enhancing the stability of the bidirectional worm 18 during rotation.

[0025] In this embodiment, preferably, one end of each of the two connecting plates 8 is fixedly provided with a first temperature sensor 23 and an electric heating rod 25, and the two mesh tubes 9 are respectively sleeved on the outside of the two electric heating rods 25.

Openings 27 are provided on both sides of the front of the box body 1, and a touch screen all-in-one machine 30 is fixed on the front of the box body 1. Cold air is respectively supplied to the interior of the experimental chamber 3 and the comparison chamber 4 through the two refrigeration chambers 5, thereby lowering the temperature inside the experimental chamber 3 or the temperature inside the comparison chamber 4, which is convenient for adjusting the temperature after testing the thermal insulation properties of the fabric. The refrigeration chamber 5 is a prior art and will not be described in detail.

[0027] In this embodiment, preferably, the inner walls of the two openings 27 are connected with sealed doors 28, and a hidden handle 29 is fixed on the front of the sealed door 28, and an insulation plate that slides with the inner wall of the insulation layer 26 is fixed on the back of the sealed door 28. The interior of one opening 27 is connected with the interior of the experimental chamber 3, and the interior of the other opening 27 is connected with the interior of the comparison chamber 4. The experimental chamber 3 and the comparison chamber 4 are sealed by the sealed door 28 to avoid airflow between the gas inside the box 1 and the external gas, thereby avoiding unstable interference of the airflow on the heat transfer structure.

[0028] In this embodiment, preferably, the cutting assembly 6 includes a base 61 and a fixing assembly 7. The base 61 is fixedly arranged at the bottom end of the box body 1. A through slot 62 is provided on the surface of the base 61. The inner wall of the bottom of the through slot 62 is fixed with a bearing plate 63 by bolts. Twelve electric push rods 64 are embedded in the inner wall of the top of the through slot 62. The telescopic ends of each six corresponding electric push rods 64 are fixed with a pressing plate 65. The bottom ends of the two pressing plates 65 are fixed with a cutting knife 66. The inner wall of the top of the through slot 62 is provided with a sliding hole to pass the constant temperature insulation composite elastic knitted yarn through. Through the through slot 62, straighten it by hand, and make its bottom end fit the top of the supporting plate 63, start the electric push rod 64, the electric push rod 64 pushes the pressing plate 65 and the cutting knife 66 to move downward, and the two cutting knitting knitting yarns are cut on both sides, thereby changing the width of the constant temperature insulation composite elastic knitting yarn so that it can be wound on the surface of the mesh tube 9, thereby improving the installation efficiency of the fabric. The supporting plate 63 can be made of wood to protect the cutting knife 66. After the supporting plate 63 is damaged, the bolts can be removed and the supporting plate 63 can be replaced, which is more flexible.

[0029] In this embodiment, preferably, the fixing component 7 includes a telescopic cylinder 71, which is embedded in the inner wall at the top of the through groove 62. The telescopic end of the telescopic cylinder 71 is fixed with a pressing frame 72, and the top of the pressing frame 72 is provided with a sliding rod 73 that slides with the sliding hole. The bottom end of the pressing frame 72 is fixed with a buffer pad 74. When the telescopic cylinder 71 is started, the telescopic end of the telescopic cylinder 71 will move downward and push the pressing frame 72. The pressing frame 72 presses the constant temperature and heat preservation composite stretch knitted yarn downward through the buffer pad 74, which is conducive to enhancing the cutting quality.

[0030] In this embodiment, preferably, the two electric heating rods 25, the two second temperature sensors 24, the two first temperature sensors 23, the two servo motors 20, the two telescopic cylinders 71 and the twelve electric push rods 64 are all electrically connected to the touch screen all-in-one 30, and the temperature values ​​measured by the two second temperature sensors 24 and the two first temperature sensors 23 are displayed through the touch screen all-in-one 30 and the above-mentioned electrical appliances are controlled.

[0031] During use, the two sealed doors 28 are first opened in sequence, so that the interior of the experimental chamber 3 and the interior of the comparison chamber 4 are connected to the outside world, so that the temperature inside the experimental chamber 3 and the temperature inside the comparison chamber 4 are the same as the outside world. At this time, no cloth is wrapped around the surface of the mesh cylinder 9, so that the gas temperature inside the two mesh cylinders 9 is the same as the outside world. Then, the constant temperature insulation composite stretch knitted yarn is cut by the cutting component 6, and a cloth of appropriate width is wrapped around the surface of the mesh cylinder 9 inside the experimental chamber 3;

[0032] After winding, the servo motor 20 is started. The servo motor 20 drives the slave bevel gear 22 to rotate through the main bevel gear 21. The slave bevel gear 22 drives the two bidirectional screws 13 to rotate through the bidirectional worm 18 and the two worm wheels 14. The two bidirectional screws 13 drive the four arc-shaped clamping blocks 16 to move. The four arc-shaped clamping blocks 16 push the anti-slip pads 17 to move, prompting the four anti-slip pads 17 to press the fabric tightly, completing the installation of the fabric. When installing the fabric to be tested, no bolts and hoops are required, which is more convenient.

[0033] Then close the two sealed doors 28 and start the two electric heating rods 25. The two electric heating rods 25 release heat and increase the gas temperature in the internal space of the two mesh tubes 9. The gas will exchange heat with the gas outside the mesh tube 9 to increase the temperature inside the experimental chamber 3 and the temperature inside the comparison chamber 4. The display screen of the touch screen all-in-one 30 will display the temperature transmitted by the two first temperature sensors 23 and the temperature transmitted by the two second temperature sensors 24. Compare the changes in the values ​​of the two second temperature sensors 24. If the increase in the temperature inside the experimental chamber 3 is less than that of the comparison chamber 4 within the same time period, it can be explained that the constant temperature insulation composite stretch knitted yarn has strong thermal insulation performance. Similarly, other types of fabrics can be fixed on the surface of the mesh tube 9 of the comparison chamber 4, and then intuitively compare which fabric has stronger thermal insulation performance to enhance practicality.

[0034] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
