Technical Field

[0001] This utility model relates to the field of sweater manufacturing technology, and in particular to a sweater breathability testing device. Background Technology

[0002] A sweater is a garment made of wool, either machine-knitted or hand-knitted.

[0003] Different uses require different levels of breathability. Quantifying the breathability of sweaters helps workers better understand their quality, thus ensuring that sweaters better meet the needs of users. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a sweater breathability testing device, which solves the technical problem that existing sweaters do not undergo quantitative breathability testing, and workers are unaware of the breathability effect of sweaters.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A sweater breathability testing device includes two symmetrical first force-bearing rods, a second force-bearing rod fixed between the two first force-bearing rods, and a first connecting block, a second connecting block, and a third connecting block that are adjustable and slidable along the length of the second force-bearing rod. One end of the first connecting block is provided with several strips of fabric, and one end of the second connecting block is provided with a storage frame for restricting the sweater. One end of the third connecting block is provided with a third force-bearing rod, and a load block is adjustable and slidable along the length of the third force-bearing rod. One end of the load block is rotatably provided with a connecting shaft, and a fan blade is fixed on the connecting shaft.

[0007] Working principle:

[0008] The sweater to be tested is clamped in the storage frame. The distance between the first, second and third connecting blocks is adjusted. Depending on the part of the sweater to be tested, the position of the load block on the third force rod is adjusted. After the adjustment is completed, the connecting shaft is rotated, which drives the fan blades to rotate. The fan blades blow air at the sweater. The air passes through the sweater and blows onto the fabric strips. The worker judges the breathability of the sweater by observing the degree of tilt of the fabric strips.

Detailed Implementation

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] Example:

[0019] like Figure 1As shown, a sweater breathability testing device includes two symmetrical first force-bearing rods 16, with a second force-bearing rod 39 fixed between the two first force-bearing rods 16. The second force-bearing rod 39 is slidably equipped with a first connecting block 15, a second connecting block 18, and a third connecting block 22 along its length. One end of the first connecting block 15 is provided with several fabric strips 13. The number of fabric strips 13 can be adjusted according to actual conditions. Preferably, in this embodiment, there are four fabric strips 13. The degree of inclination of the fabric strips 13 after being blown by the wind can be used to intuitively and clearly determine the breathability of the sweater. One end of the second connecting block 18 is fixed with a... The storage frame 23 restricts the sweater and can clamp and detect sweaters of different sizes. A third force rod 38 is provided at one end of the third connecting block 22. The third force rod 38 is slidably mounted on a carrying block 24 in the length direction. A connecting shaft 28 is rotatably mounted at one end of the carrying block 24. A fan blade 29 is fixed on the connecting shaft 28. A drive motor 27 is fixed at one end of the carrying block 24. The connecting shaft 28 is poweredly connected to the output end of the drive motor 27. The carrying block 24 drives the fan blade 29 to move, which can blow air to detect different parts of the sweater. Support rods 14 are fixed at both ends of each first force rod 16.

[0020] The sweater to be tested is clamped in the storage frame 23. The distance between the first connecting block 15, the second connecting block 18 and the third connecting block 22 is adjusted. Depending on the part of the sweater to be tested, the position of the carrying block 24 on the third force rod 38 is adjusted. After the adjustment is completed, the connecting shaft 28 is rotated. The connecting shaft 28 drives the fan blade 29 to rotate. The fan blade 29 blows air at the sweater. The air passes through the sweater and blows onto the fabric strip 13. The worker judges the breathability of the sweater by observing the degree of inclination of the fabric strip 13.

[0021] The inner walls on both sides of the storage frame 23 are symmetrically provided with several adjustment slots 20, preferably, such as Figure 3 As shown, in this embodiment, there are four adjustment slots 20. The adjustment slots 20 are evenly opened on the inner walls of both sides of the storage frame 23. A first connecting rod 34 is slidably provided in each adjustment slot 20 along the length direction. An elastic element 33 is connected between the first connecting rod 34 and the corresponding adjustment slot 20. Pulling the first connecting rod 34 allows it to move closer to or away from the adjustment slot 20, thereby enabling the first clamping plate 12 and the second clamping plate 11 to cooperate in clamping sweaters of different shapes. The first clamping plate 12 is fixedly provided at one end of the first connecting rod 34. Two mounting plates 10 are fixedly provided at one end of the first clamping plate 12. A force-bearing shaft 31 is provided between the two mounting plates 10. The second clamping plate 11 is rotatably provided on the force-bearing shaft 31. A torsion spring 32 is provided between the second clamping plate 11 and the force-bearing shaft 31.

[0022] like Figure 2As shown, a lead screw 36 is rotatably provided at one end of the third connecting block 22. The lead screw 36 is opposite to the third force-bearing rod 38. A turntable 35 is fixed at the end of the lead screw 36. The turntable 35 facilitates rotation by the worker. A fourth connecting block 37 is threadedly connected to the lead screw 36. The fourth connecting block 37 is slidably provided along the length of the third force-bearing rod 38. A fourth force-bearing rod 26 is fixed between the two fourth connecting blocks 37. The load block 24 is slidably disposed on the fourth force-bearing rod 26.

[0023] One end of the carrying block 24 is provided with a protective cover 25, and the drive motor 27 is installed inside the protective cover 25. The protective cover 25 is a closed structure, which allows the wind generated by the fan blade 29 to be accurately directed at the sweater. A protective cover 30 is fixed inside the protective cover 25. The protective cover 30 is used to isolate the fan blade 29 from the outside world and plays a role in installation protection.

[0024] The first connecting block 15 is threadedly connected to the first screw 17 with a nut, the end of the first screw 17 abutting against one end of the second force-bearing rod 39; the second connecting block 18 is threadedly connected to the second screw 19 with a nut, the end of the second screw 19 abutting against one end of the second force-bearing rod 39; and the third connecting block 22 is threadedly connected to the third screw 21 with a nut, the end of the third screw 21 abutting against one end of the second force-bearing rod 39.

[0025] Working principle:

[0026] Based on the actual situation, after loosening the first screw 17, the second screw 19, and the third screw 21, adjust the distance between the first connecting block 15, the second connecting block 18, and the third connecting block 22. After adjustment, screw in the first screw 17, the second screw 19, and the third screw 21, and rotate the four second clamping plates 11 respectively, so that the second clamping plates 11 cooperate with the first clamping plates 12 to fix the sweater. After fixing, manually rotate the turntable 35. The turntable 35 drives the lead screw 36 to rotate. The lead screw 36 drives the fourth force rod 26 to move through the fourth connecting block 37. The fourth force rod 26 drives the load block 24 to move along the length of the fourth force rod 26. The load block 24 drives the transmission motor 27 to move. Start the transmission motor 27. The transmission motor 27 drives the fan blade 29 to rotate through the connecting shaft 28. The fan blade 29 blows air. After passing through the sweater, the air blows towards the fabric strip 13, causing the fabric strip to tilt.
