Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of down bulkiness detection, in particular to a device for detecting down bulkiness. Background Art
[0002] Down jackets are lightweight and offer excellent warmth, making them popular with consumers in winter. The warmth of down is closely related to its nominal fill power, which measures the volume occupied by down per unit weight. Fill power testing is a key concern for many companies. Existing down fill power testing involves placing down into a cavity and placing a pressure plate inside. This pressure plate presses down on the down, and the down volume is measured based on the height of the pressure plate. However, the need to remove the pressure plate during the down filling process is cumbersome and impacts testing efficiency.
[0003] Therefore, the patent with application number CN202321203553.8 discloses a down fluffiness meter, which can pour the down into the measuring cylinder through the gap between the pressure plate and the measuring cylinder by rotating the connecting tube to screw the semicircular plate two into the semicircular plate one, avoiding the trouble of taking the pressure plate out of the measuring cylinder and putting it back in, thereby improving the measurement efficiency; while rotating the connecting tube, the stirring rod can be driven to rotate in the measuring cylinder to stir the down evenly, thereby ensuring the accuracy of the test results; however, during the above stirring process, since the down is extremely light, it will fly upwards, and the semicircular plates one and two will continuously open and close the measuring cylinder as the connecting tube rotates, causing some of the down to fly out of the measuring cylinder and pollute the surrounding environment, and the staff will inhale the flying down and cause harm to their own health. Utility Model Content
[0004] In view of this, the purpose of the present invention is to provide a device for detecting the fluffiness of down, so as to solve the problem that the down easily flies to the outside of the device during the stirring process.
[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:
[0006] A device for detecting the fill power of down comprises a detection cylinder, a rotating shaft, and a pressing plate; the bottom of the detection cylinder is connected to a down inlet tube, and a valve is installed on the down inlet tube; the rotating shaft is vertically rotatably connected to the detection cylinder, the lower end of the rotating shaft is provided with a stirring rod, and the upper end of the rotating shaft is provided with a thread; the pressing plate is connected to the upper end of the rotating shaft via a spiral transmission of the thread, and a connecting tube is vertically provided on the upper surface of the pressing plate; the connecting tube is circumferentially fixed and axially movable through the top wall of the detection cylinder, and the connecting tube is provided with scale lines corresponding to the fill power scale values;
[0007] The pressing plate moves downward in a fixed circumferential direction under the action of gravity, thereby driving the rotating shaft to rotate, so that the stirring rod stirs the down in the detection cylinder evenly, and the pressing plate moves downward and disengages from the thread and presses down on the down.
[0008] As an optional solution, the cross-sectional shape of the connecting tube is a regular polygon, the top wall of the detection tube is provided with a through hole adapted to the cross-sectional shape of the connecting tube, and the connecting tube is inserted into the through hole.
[0009] As an optional solution, the periphery of the pressure plate is close to the inner wall of the detection cylinder; and the outer peripheral surface of the connecting tube is close to the periphery of the through hole.
[0010] As an optional solution, the stirring rod is arranged to be tilted downward from the inside to the outside.
[0011] As an optional solution, the lower end of the connecting pipe is sleeved on the rotating shaft and coaxially fixedly connected to the pressing plate.
[0012] As an optional solution, a pile outlet pipe is provided at a side of the bottom of the detection cylinder opposite to the pile inlet pipe, and a valve is installed on the pile outlet pipe.
[0013] As an optional solution, the upper end of the connecting tube is provided with a handle located outside the detection cylinder.
[0014] Due to the adoption of the above technical solution, the utility model will have the following beneficial effects:
[0015] The utility model provides a device for detecting the fluffiness of down. The device utilizes a circumferentially fixed connecting tube that is axially movable and extends through the top wall of a detection tube. This allows a pressing plate to move downwardly and circumferentially fixedly under the action of gravity, thereby driving the shaft to rotate via threads at its upper end, thereby causing a stirring rod to evenly stir the down within the detection tube. After the pressing plate moves downward and disengages the threads, the shaft stops rotating, and the pressing plate presses down on the down. The scale value on the corresponding scale line on the top wall of the detection tube represents the fluffiness value of the pressed down. Because both stirring and pressing the down are accomplished by the falling pressing plate, the operation process is simplified, saving time and manpower. Furthermore, because the down is directly fed into the detection tube from a down feed pipe via a filling device, the problem of down flying around during manual loading and removal of down is eliminated. Furthermore, when the down feed pipe is closed by a valve, it forms a closed space within the detection tube with the pressing plate, preventing the down from flying outside the device during stirring.
[0016] Therefore, compared with the prior art, the utility model does not easily prevent the down from flying outside the device during the stirring process, and the stirring operation is simple and convenient, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Please refer to Figure 1-4 In one embodiment of a device for detecting the bulkiness of down of the present utility model, the device for detecting the bulkiness of down comprises a detection cylinder 1, a rotating shaft 2 and a pressing plate 3;
[0027] Among them, a down inlet tube 11 is connected to one side of the bottom of the detection cylinder 1, and a down outlet tube 12 is connected to the other side of the bottom of the detection cylinder 1. The down inlet tube 11 and the down outlet tube 12 are both used to connect to the down filling equipment. The down inlet tube 11 and the down outlet tube 12 are respectively equipped with valves for opening and closing the down inlet tube 11; the rotating shaft 2 is vertically rotatably connected to the center position of the bottom wall of the detection cylinder 1 through a bearing, and a stirring rod 21 is integrally formed at the lower end of the rotating shaft 2. A thread is provided at the upper end of the rotating shaft 2, which can be a screw thread. The screw thread refers to a thread processed on the screw, which is usually used to convert rotational motion into linear motion. Its shape is similar to that of an ordinary thread, but it usually has a larger diameter and a deeper thread. The pressing plate 3 is connected to the upper end of the rotating shaft 2 through the above-mentioned threaded spiral transmission. A connecting tube 4 is vertically provided on the upper surface of the pressing plate 3. Specifically, the lower end of the connecting tube 4 is sleeved on the rotating shaft 2 and coaxially fixedly connected to the pressing plate 3. The inner diameter of the connecting tube 4 is slightly larger than the diameter of the thread on the rotating shaft 2; the connecting tube 4 is fixed circumferentially and moves axially to pass through the top wall of the detection cylinder 1. A scale line 41 corresponding to the fluffiness scale value is provided on the connecting tube 4.
[0028] When this embodiment is in use, down is fed directly from the down inlet pipe 11 into the detection cylinder 1 through the filling device or is sucked out from the down outlet pipe 12. Since the connecting tube 4 is fixed circumferentially and moves axially to penetrate the top wall of the detection cylinder 1, the pressing plate 3 can move downward in a fixed circumferential direction under the action of gravity, thereby driving the rotating shaft 2 to rotate through the screw transmission, so that the stirring rod 21 stirs the down in the detection cylinder 1 evenly. After the pressing plate 3 moves downward and disengages from the thread, the rotating shaft 2 stops rotating, and the pressing plate 3 presses down on the down. The scale value on the corresponding scale line 41 on the top wall of the detection cylinder 1 is the fill power value of the pressed down.
[0029] Specifically, the cross-sectional shape of the connecting tube 4 can be a regular hexagon. A through-hole corresponding to the cross-sectional shape of the connecting tube 4 is defined in the top wall of the detection cylinder 1. The connecting tube 4 is inserted into the through-hole, so that the connecting tube 4 is restricted from rotation by the through-hole, i.e., the connecting tube 4 is circumferentially fixed, while simultaneously being free to move axially, i.e., the connecting tube 4 can move up and down along the rotating shaft 2. It should be noted that the cross-sectional shape of the connecting tube 4 can also be other regular polyhedral shapes, as long as the rotation of the connecting tube 4 is restricted in principle.
[0030] More specifically, the pressing plate 3 can be set to be circular, and the diameter of the pressing plate 3 is slightly equal to the inner diameter of the detection cylinder 1. In this way, the periphery of the pressing plate 3 is close to the inner wall of the detection cylinder 1 without affecting its own upward and downward movement. Similarly, the outer peripheral surface of the connecting tube 4 can be set to be close to the periphery of the through hole, which can further prevent the down from flying upward and out of the detection cylinder 1.
[0031] Specifically, the stirring rod 21 can be tilted downward from the inside to the outside, and the angle between the tilted stirring rod 21 and the axis of the detection cylinder 1 is 60 degrees, and the end of the stirring rod 21 is close to the inner wall of the detection cylinder 1. This can ensure that the stirring rod 21 can rotate normally, effectively increase the stirring range of the stirring rod 21, and improve the stirring effect.
[0032] On this basis, a handle 5 located outside the detection cylinder 1 can be provided on the upper end of the connecting tube 4. The handle 5 is cylindrical and coaxially fixed to the upper end of the connecting tube 4 to facilitate lifting the pressure plate 3 upward.
[0033] The usage method or working principle of the utility model is as follows:
[0034] First, the pressing plate 3 is pulled upward through the connecting tube 4, and then the down filling device is used to directly feed the down from the down inlet tube 11 into the detection cylinder 1, and the down inlet tube 11 is closed through the valve on the down inlet tube 11, and then the pressing plate 3 is lowered. Since the connecting tube 4 is fixed circumferentially and moves axially through the top wall of the detection cylinder 1, the pressing plate 3 can move downward circumferentially under the action of gravity, thereby driving the rotating shaft 2 to rotate through the thread at the upper end of the connecting rod, so that the stirring rod 21 stirs the down in the detection cylinder 1 evenly; after the pressing plate 3 moves downward and disengages from the thread, the rotating shaft 2 stops rotating, and the pressing plate 3 presses down on the down. The scale value on the corresponding scale line 41 on the top wall of the detection cylinder 1 is the fill power value of the pressed down; finally, the down outlet tube 12 is opened through the valve on the down outlet tube 12, and the down filling device is used to directly suck the down out of the down outlet tube 12.
[0035] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
