[0002] In the field of filament processing, the precursor rack is one of the most critical equipment. With the continuous progress of modern industry and the continuous expansion of the scope of filament applications, the efficiency, quality and automation of filament processing have been put forward more and more stringent requirements. This has led to the emergence of multifunctional precursor racks.

[0003] For example, an existing patent (publication number: CN217556390U) discloses a raw yarn rack for a stretch yarn machine, including a base body, a support rod is provided on the base body, a screw rod is provided on the support rod, the screw rod is arranged horizontally, and the end of the screw rod is threadedly connected to a cylindrical bracket, a radial pin is provided on the bracket, a baffle is rotatably connected to the radial pin, a notch is provided on the bracket for the rotation of the baffle, and a limit member located on the outside of the baffle is provided on the bracket.

[0004] However, the yarn rack of the elastic yarn machine designed as described above still has some shortcomings in actual use: the device will push the baffle to rotate upward to a horizontal position through the yarn tube and then be supported by the inner wall of the yarn tube. After that, due to the presence of the limiter, the baffle 7 rotates to be perpendicular to the wire hanging rod 3 and stops rotating. In this process, the rotation of the baffle and the force supporting the inner wall of the yarn tube can easily cause scratches on the inner wall of the yarn tube. Over time, the yarn tube is easily damaged and requires staff to check and replace it regularly, which increases the economic cost.

[0005] Therefore, we designed a multifunctional raw yarn rack for filament processing to solve the above problems. Utility Model Content

[0011] Furthermore, there are multiple negative pressure holes, which are evenly arranged on the hanging wire rod.

[0012] Furthermore, the raw silk tube is made of stainless steel.

[0013] Furthermore, the surface of the handle is provided with anti-slip textures.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: when the raw silk tube needs to be fixed, the raw silk tube is put on the hanging wire rod, so that one end of the raw silk tube is magnetically connected to the baffle, and then the other end of the raw silk tube is threadedly connected to it through the screw cover to seal it, and then the vacuum pump is started, and the gap between the hanging wire rod and the raw silk tube is evacuated through the negative pressure hole to form a vacuum state, so that a negative pressure state is formed, and the raw silk tube is firmly adsorbed on the hanging wire rod, thereby preventing the raw silk tube from being displaced by external force during work, and at the same time, the negative pressure adsorption method is adopted to avoid the inner wall of the raw silk tube from being scratched by the component, thereby extending the service life of the raw silk tube and reducing economic costs.

The number of distribution pipes 9 corresponds to the number of hanging wire rods 3, and the other end of the distribution pipe 9 is arranged in the hanging wire rod 3.

[0022] During specific implementation, when it is necessary to fix the raw silk tube 4, the raw silk tube 4 is put on the hanging wire rod 3, so that one end of the raw silk tube 4 is magnetically connected to the baffle 5, and then the other end of the raw silk tube 4 is threadedly connected to it through the screw cover 402 to seal it, and then the vacuum pump 6 is started, and the gap between the hanging wire rod 3 and the raw silk tube 4 is evacuated through the negative pressure hole 301 to form a vacuum state, so that a negative pressure state is formed, and the raw silk tube 4 is firmly adsorbed on the hanging wire rod 3, so as to prevent the raw silk tube 4 from being displaced by external force during operation, and at the same time, the negative pressure adsorption method is adopted to prevent the inner wall of the raw silk tube 4 from being scratched by the component, thereby extending the service life of the raw silk tube 4 and reducing the economic cost.

[0023] See Figure 1 as well as Figure 3As shown, a cavity is opened in the hanging screw rod 3, a valve 302 is arranged in the cavity, a rotating handle 303 is installed on the valve 302, and the rotating handle 303 is arranged outside the hanging screw rod 3. One end of the distribution pipe 9 extends to the cavity in the hanging screw rod 3 and is connected to one end of the valve 302. The bottom surface of the valve 302 is arranged on the inner wall of the hanging screw rod 3, and the surface of the rotating handle 303 is provided with anti-slip texture.

[0024] In specific implementation, when there is an unnecessary raw silk tube 4 on the support rod 2, the handle 303 on the corresponding screw rod 3 is rotated to close the corresponding valve 302, that is, the raw silk tube 4 on the screw rod 3 does not generate negative pressure, and the raw silk tube 4 on the screw rod 3 can be used as needed; the flexibility of the raw silk tube 4 when using is improved, and the practicality of the device is increased.

[0025] See Figure 1 The raw silk tube 4 is sleeved on the outer wall of the hanging wire rod 3. An iron sheet 401 is provided at one end of the raw silk tube 4 close to the baffle 5. The iron sheet 401 is arranged in the raw silk tube 4. A magnet is arranged in the baffle 5. The iron sheet 401 is magnetically connected to the magnet.

[0026] During specific implementation, a baffle 5 is provided on the wire rod 3, and the baffle 5 is tightly connected to the outer wall of the wire rod 3, and the raw wire tube 4 and the iron sheet 401 at one end of the raw wire tube 4 are magnetically connected. The iron sheet 401 is arranged in the raw wire tube 4, and is connected to the iron sheet 401 through the baffle 5 to seal one end of the raw wire tube 4 to prevent air leakage. The magnetic connection between the raw wire tube 4 and the baffle 5 also provides a certain stability for the raw wire tube 4.

[0029] See Figure 2 The raw yarn drum 4 is made of stainless steel. Stainless steel itself has excellent strength and hardness, which makes the raw yarn drum 4 have a strong structural load-bearing capacity. Its smooth surface is conducive to the smooth winding and release of the filaments on the raw yarn drum 4, reducing the quality problems such as filament wear and scratches caused by surface defects of the raw yarn drum 4.

[0030] It should be noted that a fastening pad is provided on the inner wall of the raw silk tube 4. The material of the fastening pad is rubber. When the raw silk tube 4 is hung on the hanging wire rod 3, the fastening pad fits more closely with the surface of the hanging wire rod 3, making the raw silk tube 4 more firmly fixed. Since the fastening pad is a prior art, it will not be described in detail in this manual and is not shown in the figure.

[0031] Working principle: When the raw silk tube 4 needs to be fixed, the raw silk tube 4 is put on the hanging wire rod 3, so that one end of the raw silk tube 4 is magnetically connected to the baffle 5, and then the other end of the raw silk tube 4 is threadedly connected to it through the screw cover 402 to seal it, and then the vacuum pump 6 is started, and the gap between the hanging wire rod 3 and the raw silk tube 4 is evacuated through the negative pressure hole 301 to form a vacuum state, so that the raw silk tube 4 is firmly adsorbed on the hanging wire rod 3, so as to prevent the raw silk tube 4 from being displaced by external force during work, and at the same time, the negative pressure adsorption method is adopted to prevent the inner wall of the raw silk tube 4 from being abutted by the components to produce When there is an unnecessary raw silk tube 4 on the support rod 2, the handle 303 on the corresponding hanging screw rod 3 is turned to close the corresponding valve 302, that is, the raw silk tube 4 on the hanging screw rod 3 does not generate negative pressure, and the raw silk tube 4 on the hanging screw rod 3 can be used as needed; the flexibility of the raw silk tube 4 when used is improved, and the practicality of the device is increased. When the raw silk tube 4 does not need to be restricted, the screw cover 402 is unscrewed to allow the outside air to re-enter the space between the hanging screw rod 3 and the raw silk tube 4, and normal state can be restored.
