Abstract
Description
Technical Field
[0001] This utility model relates to the field of down and feather detection, and specifically to a weighing device for down and feather detection. Background Technology
[0002] In the down and feather loft testing process, the weighing step is a crucial preliminary step. Typically, operators place the down and feathers into a graduated cylinder on a weighing platform for weighing. However, most graduated cylinders currently used lack caps, which means that during the weighing process, the lightweight and easily dispersed down and feathers are highly likely to scatter, resulting in weight loss and significantly reducing the accuracy of the weighing data.
[0003] Furthermore, when a large amount of down and feathers needs to be emptied from the measuring cylinder after testing, even after the emptying operation, a considerable amount of down and feathers will still adhere to the inner wall of the cylinder. If these residual down and feathers are not cleaned in time, they will mix into the new test samples when testing other types of down and feathers, interfering with the test results, seriously affecting the accuracy of the test, and causing deviations in the assessment of key indicators such as the loft of down and feathers, thus failing to truly reflect the actual quality of the down and feathers. Utility Model Content
[0004] This invention provides a weighing device for detecting down and feathers to solve the problems of the prior art.
[0005] The objective of this utility model can be achieved through the following technical solution: A weighing device for down and feather testing includes: a frame, a weighing platform, and a measuring cylinder. The weighing platform is slidably mounted on the frame, and a mounting plate is provided on the weighing platform. The measuring cylinder is mounted on the mounting plate, and the weighing platform weighs the measuring cylinder. A groove is provided in the middle of the mounting plate. The measuring cylinder includes a glass cylinder, an end cap, a circular scraper, a wrap-around O-ring seal, a short connecting rod, and a long rod. The end cap is fitted onto the glass cylinder to seal the top of the glass cylinder. A through hole coaxial with the groove is provided in the center of the bottom of the glass cylinder. The circular scraper is located inside the glass cylinder. The wrap-around O-ring seal is located outside the circular scraper and is tightly fitted to the inner wall of the glass cylinder. A threaded hole is provided in the middle of the circular scraper. The short connecting rod passes through the through hole and is threadedly connected to the threaded hole. In the weighing state, the short connecting rod is located in the groove. In the weighing end state, the long rod is connected to the lower end of the short connecting rod.
[0006] In a further improvement, the weighing platform has a square groove in the middle, and the lower end of the mounting plate is located inside the square groove.
[0007] In a further improvement, a limiting post is provided around the mounting plate, and the glass cylinder is located inside the limiting post, thereby restricting the movement of the glass cylinder in the plane by the limiting post.
[0008] In a further improvement, two sets of slide rails are symmetrically fixed on the frame, and the weighing platform is slidably mounted on the slide rails.
[0009] In a further improvement, the long rod is threaded to the lower end of the short connecting rod.
[0010] Compared with existing technologies, the beneficial effects of this new weighing device for detecting down and feathers are as follows:
[0011] This weighing device for down and feather testing achieves accurate weighing of down and feathers through the coordinated arrangement of a frame, weighing platform, and measuring cylinder. In weighing mode, the short connecting rod is positioned within the groove, at which point the measuring cylinder is stably placed on the mounting plate, and the end cap is placed over the top of the cylinder. The weighing platform weighs the measuring cylinder, and the end cap prevents down and feathers from scattering and flying out, maintaining weighing accuracy.
[0012] After weighing, the long rod connects to the lower end of the short connecting rod. Pulling the long rod causes the short connecting rod to rise, which in turn causes the circular scraper, which is wrapped with an O-ring seal, to move upward inside the glass cylinder. The O-ring seal on the outside scrapes off the down feathers adhering to the inner wall of the cylinder, making cleaning easier and greatly preventing residual down feathers from mixing into new test samples and interfering with the test results.

[0019] The following describes the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.
[0020] Example 1
[0021] A weighing device for detecting down and feathers includes: a frame 1, a weighing platform 2, and a measuring cylinder 3. The weighing platform 2 is slidably mounted on the frame 1. A mounting plate 4 is provided on the weighing platform 2. The measuring cylinder 3 is mounted on the mounting plate 4. The weighing platform 2 weighs the measuring cylinder 3. A groove 41 is provided in the center of the mounting plate 4. The measuring cylinder 3 includes a glass cylinder 31, an end cap 32, a circular scraper 33, a wrap-around O-ring seal 34, a short connecting rod 35, and a long rod 36. The end cap 32 is fitted onto the glass cylinder 31, sealing the top of the glass cylinder 31. The bottom center of the glass cylinder 31 is provided with a through hole 311 coaxial with the groove 41. The circular scraper 33 is disposed inside the glass cylinder 31. The encapsulated O-ring seal 34 is disposed outside the circular scraper 33 and is tightly fitted to the inner wall of the glass cylinder 31. The circular scraper 33 is provided with a threaded hole 331 in the middle. The short connecting rod 35 passes through the through hole 311 and is threadedly connected to the threaded hole 331. In the weighing state, the short connecting rod 35 is located in the groove 41. In the weighing end state, the long rod 36 is connected to the lower end of the short connecting rod 35.
[0022] like Figures 1-4 As shown, the working principle of this utility model is as follows:
[0023] This weighing device for down and feather testing achieves accurate weighing of down and feathers through the coordinated arrangement of a frame, weighing platform, and measuring cylinder. In weighing mode, the short connecting rod is positioned within the groove, at which point the measuring cylinder is stably placed on the mounting plate, and the end cap is placed over the top of the cylinder. The weighing platform weighs the measuring cylinder, and the end cap prevents down and feathers from scattering and flying out, maintaining weighing accuracy.
[0024] After weighing, remove the long rod from the mounting plate of the measuring cylinder. The operator opens the end cap and grasps the short connecting rod at the bottom of the cylinder to prevent the circular scraper from moving and falling out during the pouring of down and feathers. After pouring out a large amount of down and feathers, connect the long rod to the lower end of the short connecting rod. Pulling the long rod causes the short connecting rod to rise, which in turn causes the circular scraper, which is wrapped with an O-ring seal, to move upward inside the glass cylinder. The O-ring seal on the outside scrapes off the down and feathers adhering to the inner wall of the cylinder, making cleaning easier and greatly preventing residual down and feathers from mixing into new test samples and interfering with the test results.
[0025] The transparent glass cylinder allows operators to directly observe the condition of the down and feathers inside during testing, including their quantity and distribution. This helps in the timely detection of anomalies and ensures the accuracy of the test. Simultaneously, the relatively smooth glass material reduces the adhesion of down and feathers, facilitating cleaning. The encapsulated O-ring seal, located on the outside of the circular scraper and tightly fitted to the inner wall of the glass cylinder, enhances the seal between the scraper and the inner wall of the glass cylinder.
[0026] As a further preferred embodiment, the weighing platform 2 is provided with a square groove 21 in the middle, and the lower end of the mounting plate 4 is disposed inside the square groove 21, so that the mounting plate and the weighing platform form a relatively tight fitting structure, which enhances the stability of the mounting plate on the weighing platform, thereby ensuring that the position of the measuring cylinder is fixed during the weighing process, and thus improving the accuracy of weighing.
[0027] As a further preferred embodiment, the mounting plate 4 is provided with a limiting post 41, and the glass cylinder 31 is located inside the limiting post 41. The limiting post 41 restricts the movement of the glass cylinder 31 in the plane. This prevents the glass cylinder from sliding freely on the mounting plate, ensures its stable position during the weighing operation, and guarantees the smooth progress of the testing process.
[0028] As a further preferred embodiment, two sets of slide rails 11 are symmetrically fixed on the frame 1, and the weighing platform 2 is slidably mounted on the slide rails 11. This allows the operator to easily slide the weighing platform out of its initial position on the frame, facilitating operations such as placing or removing measuring cylinders, thus improving operational convenience.
[0029] As a further preferred embodiment, the long rod 36 is threaded to the lower end of the short connecting rod 35. The long rod can be connected or disconnected from the short connecting rod by rotating it. After connection, the short connecting rod can be moved by pulling the long rod. The threaded connection method is simple to operate and has a stable connection. It is convenient to quickly separate and connect the long rod and the short connecting rod in the weighing state and the end of the weighing state, which facilitates subsequent cleaning operations.
[0030] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
