Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] According to an embodiment of the present invention, a pretreatment device for detecting down loft is provided.
[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3As shown, the pretreatment equipment for down loft testing according to an embodiment of the present invention includes a base box 1, a testing cylinder 2, and a support 3. A support 4 is welded inside the base box 1, and an electric push rod 5 is fixed to the left side of the top surface of the support 4.

A pressure plate 11 is installed at one end of the rope buckle, and the pressure plate 11 is located directly above the detection cylinder 2. In this patent, we only use the blower 7 and the electric actuator 5 without improving their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method can be adjusted and operated according to the requirements of their instruction manual, and will not be described in detail here.

[0028] Working principle:
[0029] 1. In use, the down sample is filled into the detection cylinder 2, and then the cylinder cover 10 is closed. By manually rotating the rotating rod 19 at the center of the cylinder cover 10, the rotating rod 19, under the action of the support plate 20, causes the glass rod 21 to move in a circular motion within the detection cylinder 2, initially agitating the down sample. Then, the blower 7 on the support 4 is started, causing the blower 7 to blow air through the hose 8 into the air blowing pipe 6, and then disperse it out through several through holes 22 on the surface of the air blowing pipe 6. At this time, the electric actuator 5 is activated to extend, causing the electric actuator 5, under the action of the connector 9, to extend the air blowing pipe 6 into the inside of the detection cylinder 2, so that the air blown out by the air blowing pipe 6 fills the detection cylinder 2, agitating the down sample. When the loft is measured... Remove the cap 10 of the testing cylinder 2, then remove the hanging ring 13 connected to the support column 14, allowing the pressure plate 11, connected by the hanging rope 12, to fall naturally under gravity. Observe the value of the scale line 17 on the testing cylinder 2 when the pressure plate 11 contacts the down and stops falling, and then calculate the loft of the down sample. (The conversion formula for the loft of down garments is: GB / T14272-2011 Down garments: Loft height (cm) × 29.06 = FP loft. GB / T14272-2021 Down garments: Loft height (cm) ÷ 0.0252 = FP loft. QB / T1193-2012 Down and feather quilts: Loft height (cm) × 28.77 = FP loft.)
