Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of down fluffiness detection devices, in particular to a down fluffiness detection device. Background Technique
[0002] The detection principle of down fluffiness is mainly based on the fluffy structure of down and its characteristic of containing a large amount of air. The low thermal conductivity of air makes down have good heat preservation performance, and fluffiness is one of the important indicators to measure the heat preservation performance of down products. During the detection process, the steam reduction method is usually used to simulate the fluffy state of down in the natural environment. Specifically, first, the down sample is put into a reduction box, and the down is completely wetted with steam, and then the down is completely dried with equipment such as a hair dryer to restore it to its initial fluffy state. Next, the processed down sample is put into a fluffiness measuring instrument. These instruments usually adopt a funnel-shaped feeding bucket to make the down sample slowly float into the measuring bucket and be flattened to avoid compression. After the down sample is stable, a certain pressure is applied, such as using a pressure plate to slowly descend to the surface of the sample naturally and waiting for a period of time to record the scale value of the fluffiness meter corresponding to the pressure plate.
[0003] During the process of detecting down fluffiness, generally, the operator first weighs the down sample and then puts the down sample into the measuring cylinder through a funnel for measurement. During the process of moving the down sample, since the down sample is light, some of the down sample may disperse outside during the movement of the down sample, resulting in a certain deviation in the amount of the down sample, which may lead to inaccurate measurement of the down sample fluffiness.

[0022] In order to make the technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0023] The present utility model provides a technical solution: Referring to Figures 1-6 , a device for detecting the fluffiness of down disclosed by the present utility model includes a measuring cylinder 1. A weighing mechanism 2 is provided inside and outside the measuring cylinder 1. The weighing mechanism 2 includes a pressing plate 21. The pressing plate 21 is arranged inside the measuring cylinder 1, and the outer peripheral wall of the pressing plate 21 is in contact with the inner wall of the measuring cylinder 1. Weighing pieces 23 are provided on both the upper and lower sides of the pressing plate 21. Fluffing mechanisms 3 are provided at both the upper and lower ends of the measuring cylinder 1.
[0024] In this embodiment, when the improved down fluffiness detection device is in use, the operator first places the measuring cylinder 1 upright. Due to the action of its own weight, the pressing plate 21 automatically moves downward. Subsequently, the operator slowly feeds the down raw material into the measuring cylinder 1 through the hopper. The down raw material fed into the measuring cylinder 1 falls onto the pressing plate 21, and the weight of the down raw material is measured by the weighing member 23, so as to determine the amount of the down raw material in the measuring cylinder 1. Then, the fluffing mechanism 3 is activated to inject air into the measuring cylinder 1 from the left and right sides at the upper and lower ends of the measuring cylinder 1, so that the flowing down samples in the measuring cylinder 1 drive the down samples to float in the measuring cylinder 1. Furthermore, the down raw material is further fluffed by the air flow, so that the down raw material maintains a stable fluffy state before the fluffiness measurement. Finally, the measuring cylinder 1 is inverted, and the pressing plate 21 moves downward under the action of its own gravity to press the down samples in the measuring cylinder 1 for a specific time. After the pressing plate 21 finishes pressing the down raw material, the operator reads the scale value according to the position of the pressing plate 21, so as to obtain the fluffiness of the down raw material.
[0025] In a further preferred embodiment of the present utility model, as Figure 6 shown, the weighing member 23 includes a display panel 231, the display panel 231 is fixedly installed on the outer peripheral wall of the measuring cylinder 1, and a plurality of pressure sensors 232 are arranged in a circumferential array on the bottom side of the pressing plate 21, and the bottom end of each pressure sensor 232 is in contact with the inner wall of the measuring cylinder 1;
[0026] In this embodiment, after the down raw material is fed into the measuring cylinder 1, the down raw material directly falls onto the disc, so that the overall gravity of the pressing plate 21 gradually increases. At this time, the operator can determine the amount of the down raw material in the measuring cylinder 1 according to the reading on the display panel 231, so as to stop feeding the down raw material into the measuring cylinder 1 when the down raw material reaches the required amount.
[0027] In a further preferred embodiment of the present utility model, as Figure 6 shown, a circular hole 233 is opened at the central position of the bottom side of the measuring cylinder 1, and the circular hole 233 is located between a plurality of pressure sensors 232. A handle 234 with a T-shaped cross-section is fixedly installed at the central position of the bottom side of the pressing plate 21, and the bottom end of the handle 234 is inserted into the circular hole 233;
[0028] In this embodiment, when the pressing plate 21 moves downward in the measuring cylinder 1, the gas in the measuring cylinder 1 can be directly discharged to the outside through the circular hole 233, and the gas at the bottom of the measuring cylinder 1 will not affect the downward movement of the push plate. When the pressing plate 21 moves toward the top of the measuring cylinder 1, the outside gas can directly flow into the measuring cylinder 1 through the circular hole 233, and a negative pressure cavity will not be formed at the bottom of the measuring cylinder 1 to affect the movement of the pressing plate 21 toward the top of the measuring cylinder 1.
[0029] In a further preferred embodiment of the present utility model, asFigure 3 and Figure 6 As shown, a sieve plate 235 is fixedly mounted on the top of the measuring cylinder 1, and the sieve plate 235 penetrates the cylinder wall of the measuring cylinder 1, and a plurality of groups of connecting holes 236 are opened in a circumferential array on the pressure plate 21, and each group of connecting holes 236 is arranged in a circumferential row;
[0030] In this embodiment, when the pressure plate 21 is located in the measuring cylinder 1 and moves downward, external gas flows into the measuring cylinder 1 through the holes in the sieve plate 235, thereby preventing a negative pressure cavity from being formed at the top of the measuring cylinder 1 and affecting the downward movement of the pressure plate 21. When the pressure plate 21 moves toward the top of the measuring cylinder 1, the gas at the top of the measuring cylinder 1 is discharged through the holes in the sieve plate 235 or passes through the connecting hole 236 over the pressure plate 21 and is discharged from the circular hole 233, thereby preventing the air at the top of the measuring cylinder 1 from affecting the movement of the pressure plate 21 toward the top of the measuring cylinder 1.
[0031] In a further preferred embodiment of the present invention, Figures 2-4 As shown, the fluffing mechanism 3 includes a filter cartridge 31, which is threadedly mounted on the right end of the top side of the measuring cylinder 1, and the filter cartridge 31 penetrates the cylinder wall of the measuring cylinder 1;
[0032] In this embodiment, when stuffing the down fluff into the measuring cylinder 1, the operator twists the filter cartridge 31 out of the measuring cylinder 1, then inserts the hole into the top hole of the measuring cylinder 1, and slowly stuffs the down fluff into the measuring cylinder 1 through the hole.
[0033] In a further preferred embodiment of the present invention, Figures 2-5 As shown, a threaded tube 32 is threadedly mounted on the left end of the bottom side of the filter cartridge 31, and the threaded tube 32 penetrates the wall of the filter cartridge 31, and the threaded tube 32 is located on the outer peripheral side of the plurality of pressure sensors 232, a filter plate 33 is fixedly mounted in the threaded tube 32, a motor 34 is fixedly mounted on the top side of the filter plate 33 and in the filter cartridge 31, and an impeller 35 is fixedly mounted on the driving end of the motor 34;
[0034] In this embodiment, when the down material is inserted into the measuring cylinder 1, the motor 34 in the threaded cylinder drives the impeller 35 to rotate slowly, so that the gas in the threaded tube 32 is slowly pushed out, so that a negative pressure chamber is continuously formed in the threaded tube 32, so that part of the gas in the fixed cylinder is sucked into the threaded tube 32 to replenish the lost gas in the threaded tube 32, and at the same time, the external gas continues to pass through the holes of the sieve plate 235 into the measuring cylinder 1 to replenish the lost gas in the measuring cylinder 1, and finally an airflow from top to bottom is formed in the measuring cylinder 1, so as to prevent the down material inserted in the measuring cylinder 1 from floating up and affecting the weighing of the down material;
[0035] After the feeding of the above-mentioned down raw materials is completed, the motor 34 in the screw tube 32 drives the impeller 35 to rotate in the reverse direction for a specific time, pushing the gas in the screw tube 32 to flow through the connection hole 236 into the measuring cylinder 1. At the same time, the motor 34 in the filter cylinder 31 drives the impeller 35 to rotate in the reverse direction synchronously, pushing the gas stored in the screw tube 32 to flow through the connection hole 236 into the measuring cylinder 1. The air flow injected into the measuring cylinder 1 from the upper and lower ends and the left and right sides drives the down raw materials to float in the measuring cylinder 1, so as to further fluff the down raw materials through the air flow.
[0036] Working principle: When the improved down fluffiness detection device is in use, the operator first squares the measuring cylinder 1. Due to the action of the self-weight of the pressure plate 21, the pressure plate 21 moves downward until the bottom side of the pressure plate contacts the detection end of the pressure sensor 232. Then the operator unscrews the filter cylinder 31 from the measuring cylinder 1, and then slowly inserts the down raw materials into the measuring cylinder 1 through the feed hopper. At the same time, the motor 34 in the screw cylinder drives the impeller 35 to rotate slowly, so as to slowly push out the gas in the screw tube 32, so that a negative pressure cavity is continuously formed in the screw tube 32, so as to suck part of the gas in the fixed cylinder into the screw tube 32 to supplement the lost gas in the screw tube 32. At the same time, the external gas continuously passes through the holes of the sieve plate 235 into the measuring cylinder 1 to supplement the lost gas in the measuring cylinder 1. Finally, an air flow from top to bottom is formed in the measuring cylinder 1;
[0037] It should be noted that during the process of the gas flowing from top to bottom in the above-mentioned measuring cylinder 1, due to the slow gas flow, it can normally pass through the connection hole 236 and cross the pressure plate 21 without applying a thrust to the pressure plate 21;
[0038] When the above operator inserts the down raw materials into the measuring cylinder 1, due to the pushing of the flowing gas in the fixed cylinder on the down raw materials and the action of the self-gravity of the down raw materials, the down raw materials move downward and fall on the pressure plate 21, so that the overall gravity of the pressure plate 21 gradually increases. At this time, the operator can determine the amount of down raw materials in the measuring cylinder 1 according to the reading on the display panel 231, so as to stop the input of down raw materials in the measuring cylinder 1 when the down raw materials reach the required amount;
[0039] After the feeding operation of the down raw materials is completed, the operator rotates the screw tube 32 so that the top end of the screw tube 32 fits against the bottom side of the pressure plate 21;
[0040] It should be noted that when the screw tube 32 is screwed, the pressure plate 21 can be rotated through the handle 234 so that the top opening of the screw tube 32 is located below the corresponding set of connection holes 236;
[0041] After the position adjustment of the above-mentioned threaded pipe 32 is completed, the motor 34 inside the threaded pipe 32 drives the impeller 35 to rotate in the reverse direction for a specific time, pushing the gas inside the threaded pipe 32 to flow through the connecting hole 236 into the measuring cylinder 1. At the same time, the motor 34 inside the filter cylinder 31 drives the impeller 35 to rotate in the reverse direction synchronously, pushing the gas stored inside the threaded pipe 32 to flow through the connecting hole 236 into the measuring cylinder 1. The airflow injected into the measuring cylinder 1 from the upper and lower ends and the left and right sides drives the down feather raw materials to float inside the measuring cylinder 1, so as to further fluff the down feather raw materials through the airflow. After the impeller 35 stops rotating, due to the action of the self-gravity of the down feather raw materials, the down feather raw materials fall again;
[0042] It should be noted that when the above-mentioned impeller 35 pushes the gas into the measuring cylinder 1, the external gas continuously passes through the holes of the filter cylinder 31 and the holes of the filter plate 33, and continuously flows into the filter cylinder 31 and the threaded pipe 32 to supplement the lost gas inside the filter cylinder 31 and the threaded pipe 32. And due to the blocking of the filter cylinder 31 and the filter plate 33, the dust and sundries of the gas are blocked outside the measuring cylinder 1;
[0043] When the above-mentioned further fluffing treatment of the down feather raw materials is carried out or after the further fluffing treatment of the down feather raw materials is completed, the operator can hold the handle 234 to restrict and position the pressing plate 21. Then, the measuring cylinder 1 is inverted. After the measuring cylinder 1 is inverted, the operator inserts the arm into the measuring cylinder 1 from the round hole 233, and then slowly lowers the pressing plate 21 until the pressing plate 21 contacts the down feather raw materials. Then, the pressing plate 21 is released, so that the pressing plate 21 freely falls under its own gravity to press the down feather raw materials for a specific time. After the pressing plate 21 presses the down feather raw materials, the operator reads the scale value according to the position of the pressing plate 21, so as to obtain the fluffiness of the down feather raw materials.
[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection required by the present invention is defined by the appended claims and their equivalents.
