Description

Technical Field

[0001] This utility model relates to the field of down production technology, and in particular to a weighing component and a device for detecting the fill power in down products. Background Technology

[0002] In the down processing industry, accurate weighing of raw down is a crucial step in ensuring product quality and production efficiency. Traditional down weighing methods often rely on manual operation, which is not only inefficient but also susceptible to human error, leading to inaccurate results. Furthermore, down's lightweight and easily dispersed nature means it can easily become airborne during weighing, affecting accuracy and potentially posing health risks to workers.

[0003] With the advancement of technology and the development of automation, some automated or semi-automated down weighing equipment has emerged in the market. However, these devices are often complex in structure, cumbersome to operate, and costly, making them unsuitable for widespread application in small and medium-sized enterprises. Therefore, it is particularly important to develop a weighing component that is simple in structure, easy to operate, accurate in weighing, and can effectively prevent down from scattering. Thus, we propose a weighing component and a down filling detection device for down products to address the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where traditional down weighing methods rely heavily on manual operation, which is not only inefficient but also susceptible to human factors leading to inaccurate weighing results. Therefore, this invention proposes a weighing component and a down filling quantity detection device for down products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A weighing assembly includes a base frame, a weighing chamber fixedly mounted on the base frame, an air pump fixedly mounted on one side of the weighing chamber, a dustproof screen fixedly mounted on the air pump's suction end, a flexible hose fixedly mounted on the inner wall of the other side of the weighing chamber, one end of the flexible hose extending to the outside of the weighing chamber and fixedly mounted with a handle tube, and a lint removal tube fixedly mounted on one end of the handle tube. The weighing assembly also includes:

[0007] The weighing mechanism is located inside the weighing box, and its bottom extends to the bottom of the weighing box and is connected to the bottom of the weighing box.

[0008] Preferably, the weighing mechanism includes a mounting box fixedly installed at the bottom of the weighing box, two weight sensors are symmetrically fixedly installed on the bottom inner wall of the mounting box, a material support assembly is provided inside the weighing box, the bottom of the material support assembly penetrates through the bottom inner wall of the weighing box and extends into the mounting box, and the material support assembly is in contact with the two weight sensors.

[0009] Preferably, the material support assembly includes a support plate located inside the weighing box, with two pressure rods symmetrically fixedly installed at the bottom of the support plate. The bottom ends of the two pressure rods penetrate the weighing box and extend into the mounting box, and the pressure rods are in contact with the corresponding weight sensors.

[0010] A down filling weight detection device for down products includes a weighing component as described above, and a feeding mechanism that penetrates the top inner wall of the weighing box and is connected to the top inner wall of the weighing box.

[0011] Preferably, the feeding mechanism includes a feeding pipe that penetrates the top inner wall of the weighing box and is fixedly connected to the top inner wall of the weighing box. A retaining ring is fixedly installed at the top end of the feeding pipe, an inner lining ring is fixedly installed inside the feeding pipe, and a sealing assembly is installed inside the feeding pipe.

[0012] Preferably, the sealing assembly includes an installation rod fixedly installed inside the feeding pipe, a connecting rod slidably connected through the installation rod, a second conical cover fixedly installed at the bottom end of the connecting rod, the second conical cover fitting against the inner wall of the inner lining ring, and a tension spring sleeved on the connecting rod above the installation rod, the top and bottom ends of the tension spring being fixedly connected to the top end of the connecting rod and the top end of the installation rod, respectively.

[0013] Preferably, a first conical hood is fixedly installed inside the weighing box, and the first conical hood is used to guide the flow of gas entering the weighing box.

[0014] In this application, when it is necessary to weigh down feathers, the connecting rod can be pulled upwards first, causing the second conical cover to move upwards. At this time, the tension spring is in a stretched state, and the feeding pipe is in a connected state. The down feathers to be weighed are slowly poured in through the ring of the feeding pipe, and the down feathers will fall onto the tray. After the down feathers have been fed in, the connecting rod is released, the tension spring returns to its original state, and the second conical cover is moved to fit against the inner lining ring, sealing the feeding pipe and preventing the down feathers from escaping. After the down feathers fall onto the tray, pressure is applied to the weight sensor by the pressure rod. The weight sensor converts the weight signal into an electrical signal output. The weight sensor and the external digital sensor... Connect the display screen, and the digital display screen can show the weight detected by the weight sensor. After weighing, if it is necessary to remove the down, the air pump can be started. The air pump draws in outside air through the dust filter, which filters the air entering the weighing chamber. Guided by the first conical hood, the air flows along the inner edge of the weighing chamber, blowing the down towards the hose. After the down enters the hose, it is discharged through the handle tube and the down discharge tube. At this time, you can hold the handle tube and adjust the direction and height of the down discharge tube as needed to ensure that the down is discharged smoothly. After the down is discharged, turn off the air pump and disconnect the power.

[0015] Beneficial effects: In this utility model, the weighing component can feed down to be weighed into the weighing box through the feeding pipe via the feeding mechanism, so that the down falls onto the weighing mechanism. Furthermore, a sealing component is set in the feeding pipe, which can be used to block the feeding pipe after the down is fed in, thereby preventing the down from escaping from the feeding pipe when it is necessary to discharge the down.

[0016] In this utility model, the weighing component, through the weighing mechanism, allows the down to fall onto the material support component after it is placed into the weighing box. After receiving the weight of the down, the material support component can apply pressure to two weight sensors respectively, thereby enabling the weight of the down to be weighed using the weight sensors.

[0017] This invention prevents down from scattering during weighing by placing it into a relatively enclosed weighing box. After weighing, the down can be completely discharged, thus avoiding losses in actual use and demonstrating good practicality. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1: Refer to Figure 1-5 A weighing assembly mainly includes a base frame 1, a weighing box 2, a feeding mechanism, a weighing mechanism, an air pump 8, a dustproof net 19, a hose 16, a handle tube 17, a lint removal tube 18, and other components.

[0026] The base frame 1 serves as the supporting structure for the entire weighing assembly, on which the weighing box 2 is fixedly mounted. An air pump 8 is fixedly mounted on one side of the weighing box 2, and a dustproof net 19 is fixedly mounted on the suction end of the air pump 8 to prevent external dust and other impurities from entering the air pump 8. A flexible hose 16 is fixedly mounted on the inner wall of the other side of the weighing box 2. One end of the flexible hose 16 extends to the outside of the weighing box 2 and is fixedly mounted with a handle tube 17. One end of the handle tube 17 is fixedly mounted with a down removal tube 18 for removing down from the weighing box 2 when needed.

[0027] The feeding mechanism is designed to facilitate the feeding of down into the weighing box 2. Specifically, the feeding mechanism includes a feeding pipe 9 that penetrates the top inner wall of the weighing box 2 and is fixedly connected to the top inner wall of the weighing box 2. A retaining ring 10 is fixedly installed at the top of the feeding pipe 9 to facilitate the user pouring down in. An inner lining ring 14 is fixedly installed inside the feeding pipe 9 for use with a sealing assembly to seal the feeding pipe. The sealing assembly includes a mounting rod 11 fixedly installed inside the feeding pipe 9, with a connecting rod 12 slidably connected through the mounting rod 11. A second conical cover 13 is fixedly installed at the bottom of the connecting rod 12, and the second conical cover 13 fits against the inner wall of the inner lining ring 14. A tension spring 15 is sleeved on the connecting rod 12 above the mounting rod 11, with the top and bottom ends of the tension spring 15 fixedly connected to the top of the connecting rod 12 and the top of the mounting rod 11, respectively. In use, the user can pull the connecting rod 12 upwards to move the second conical cover 13 upwards, simultaneously putting the tension spring 15 under tension. At this time, the feeding pipe 9 is in a connected state, and down can enter the weighing box 2 through the feeding pipe 9. When the required weight of down is reached, the connecting rod 12 is released, and the tension spring 15, under tension, will move the connecting rod 12 downwards, causing the second conical cover 13 to fit against the inner wall of the inner lining ring 14, thereby sealing the feeding pipe 9 and preventing down from escaping.

[0028] The weighing mechanism is used to accurately weigh the down feathers. The weighing mechanism includes a mounting box 5 fixedly installed at the bottom of the weighing chamber 2. Two weight sensors 6 are symmetrically fixedly installed on the inner bottom wall of the mounting box 5. A material support assembly is provided inside the weighing chamber 2. The bottom of the material support assembly penetrates the inner bottom wall of the weighing chamber 2 and extends into the mounting box 5, contacting the two weight sensors 6. The material support assembly includes a support plate 3 located inside the weighing chamber 2. Two pressure rods 4 are symmetrically fixedly installed on the bottom of the support plate 3. The bottom ends of both pressure rods 4 penetrate the weighing chamber 2 and extend into the mounting box 5, contacting the corresponding weight sensors 6. After the down feathers are placed into the weighing chamber 2, they fall onto the support plate 3. After receiving the weight of the down feathers, the support plate 3 applies pressure to the corresponding weight sensors 6 through the two pressure rods 4. Upon receiving the pressure signal, the weight sensors 6 convert it into an electrical signal for output, thereby achieving accurate weighing of the down feathers.

[0029] This application can be used in the field of down production technology, or in other fields applicable to this application.

[0030] Example 2: Reference Figure 3 An improvement upon Embodiment 1: A weighing assembly, applied in the field of down production technology, includes a first conical shroud 7 fixedly installed inside the weighing chamber 2 to guide the flow of gas entering the chamber. When it is necessary to discharge down from the weighing chamber 2, an air pump 8 can be activated. The air pump 8 draws in outside air through a dustproof net 19 and, guided by the first conical shroud 7, directs the gas along the inner edge of the weighing chamber 2. This blows the down into the flexible hose 16, and finally discharges it through the down discharge pipe 18.

[0031] However, as is well known to those skilled in the art, the working principles and wiring methods of the weight sensor 6 and the air pump 8 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
