Description

Technical Field

[0001] This utility model relates to the field of spinning technology, and in particular to a spinning box with static electricity elimination function. Background Technology

[0002] The spinning box contains a melt distribution pipe, a metering pump, and spinning components. The melt is transported to the spinning box via a screw extruder, and the flow rate is precisely controlled by the metering pump, ensuring even distribution to the spinnerets at each spinning position. The melt stream is extruded through the micro-holes of the spinnerets, forming fibers. An existing patent (publication number: CN220012911U) discloses a novel spinning box. This invention uses two sets of feed pipes, a metering pump, a distribution disc, a distribution conveying pipe, and a threaded pipe filled with hot oil. Raw materials fed through different feed pipes simultaneously enter the mixing chamber via the distribution disc and distribution conveying pipe. A motor drives a stirring plate to rotate, stirring the composite raw materials to ensure uniform mixing and more homogeneous composite fibers. However, in practical applications, the continuous friction between the composite melt and the internal structure of the spinning box causes charge accumulation, generating an electrostatic effect. This not only leads to electrostatic repulsion between the fiber bundles, creating a "fluffy effect" and reducing fiber diameter uniformity, but also increases surface fuzz, making the fabric prone to pilling and affecting product quality. Therefore, we propose a spinning box with static elimination function. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a spinning box with static electricity elimination function.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] Design a spinning box with static elimination function, including a box body with two sets of melt distribution mechanisms inside. A mixing box is fixed at the bottom of the box body and connected to the output end of the melt distribution mechanism. A stirring mechanism driven by a servo motor is provided in the mixing box. A second metering pump is provided below the mixing box. The two ends of the second metering pump are respectively connected to a delivery pipe and a spinneret. The delivery pipe is connected to the mixing box. An ionizing air bar is provided on the side of the spinneret. The central axis of the air outlet of the ionizing air bar is perpendicular to the straight line of the spinneret. The ionizing air bar is connected to the box body through a mounting assembly.

[0006] In the above scheme, the melt distribution mechanism includes a distribution plate located inside the box, a support block that fits with the distribution plate is fixed inside the box, a feed pipe is connected to the top of the distribution plate through a metering pump, and multiple distribution conveying pipes are connected between the bottom of the distribution plate and the mixing box. Each distribution conveying pipe is fitted with a spiral tube containing hot oil, and both ends of the spiral tube are connected to a circulation mechanism.

[0007] In the above scheme, the circulation mechanism includes a circulation box, a support platform for connecting the circulation box is fixed on the back of the box, an isolation box is fixed on the top of the circulation box, a variable frequency hot oil pump with its output end connected to the top of the spiral tube is installed on the top of the isolation box, the other end of the variable frequency hot oil pump is connected to the circulation box through an extraction pipe, and the bottom end of the spiral tube is connected to the circulation box.

[0008] In the above scheme, the upper and lower ends of the spiral tube are respectively connected to annular tubes, the output end of the variable frequency hot oil pump is connected to an output tube, the upper annular tube is connected to the output tube through an injection tube, and the lower annular tube is connected to the circulation box through a return tube.

[0009] In the above scheme, the stirring mechanism includes a drive shaft rotatably installed in the mixing tank, the drive shaft is connected to a servo motor, a mounting sleeve is fixed on the drive shaft, and stirring blades are evenly installed on the mounting sleeve.

[0010] In the above scheme, the bottom of the mixing box is connected to a connector for connecting to the conveying pipe, a guide block is installed at the bottom of the mixing box, a positioning cylinder is fixed on the inner wall of the top of the mixing box, a guide cylinder is coaxially fixed on the mounting sleeve, and a guide groove matching the inner wall of the guide cylinder is opened on the outer wall of the positioning cylinder.

[0011] In the above scheme, the installation component includes an assembly plate connected to the housing, and the assembly plate is evenly provided with assembly holes that mate with the ends of the ion air bars.

[0012] In the above scheme, the top of the box is open and connected to a cover plate, and an inspection port is provided on the front side of the box, with an inspection cover plate connected to the inspection port.

[0013] The advantages and beneficial effects of this utility model are as follows: By setting up ion air bars and installation components, connecting the assembly plate to the box body, and then connecting the ion air bars to the assembly holes, the ion air bars are suspended below the box body. Compared with the prior art, the ion air bars output an ion air curtain to the composite fibers ejected from the spinneret. The charge in the ion air curtain neutralizes the charge accumulated by the composite fiber melt due to friction with the inside of the spinneret. On the one hand, this prevents electrostatic repulsion between fiber bundles, which would reduce the uniformity of fiber diameter. On the other hand, it prevents the fibers from adsorbing a large amount of dust from the environment due to static electricity, thus affecting the cleanliness of the fibers. In addition, it can also prevent the accumulation of static electricity from causing sparks in the fiber collecting roller, thus improving production safety. By setting up spiral tubes and installing them one by one on the distribution and conveying pipe, the raw material can fully absorb the heat radiated outward by the hot oil inside the spiral tube, improving the flowability of the raw material and thus increasing the material conveying speed.

The variable frequency hot oil pump 16 extracts the hot oil from the circulation tank 15 through the extraction pipe 17, while the oil in the spiral tube 10 with a reduced temperature flows back into the circulation tank 15 for reheating so that it can be recycled.

[0026] Furthermore, the spiral tube 10 is connected to annular tubes 11 at both the upper and lower ends, and the output end of the variable frequency hot oil pump 16 is connected to an output tube 18. The upper annular tube 11 is connected to the output tube 18 through an injection tube 12, and the lower annular tube 11 is connected to the circulation box 15 through a return tube 13.

[0027] Specifically, the isolation box 14 is equipped with a main pipe 1 and a main pipe 2.

The return pipe 13, which is connected to the lower annular pipe 11, is a branch pipe of the main pipe 2. A flow valve is installed on the injection pipe 12.

[0028] Specifically, by setting up spiral tubes 10 and installing them one by one on the distribution and conveying pipes 9, the raw materials can fully absorb the heat emitted by the hot oil inside the spiral tubes 10, thereby improving the flowability of the raw materials and increasing the conveying speed.

[0029] A mixing box 20 connected to the output end of the melt distribution mechanism is fixed at the bottom of the box 1. The mixing box 20 is equipped with a stirring mechanism driven by a servo motor 21.

[0030] Furthermore, the stirring mechanism includes a drive shaft 22 rotatably mounted inside the mixing chamber 20, the drive shaft 22 being connected to a servo motor 21, a mounting sleeve 23 being fixed on the drive shaft 22, and stirring blades 24 being evenly mounted on the mounting sleeve 23;

The stability of the drive shaft 22 is improved by using the guide cylinder 25 and the positioning cylinder 26.

[0033] The spinneret 33 is provided with an ion air bar 36 on its side. The central axis of the air outlet of the ion air bar 36 is perpendicular to the straight line where the spinneret 33 is located, and the ion air bar 36 is connected to the housing 1 through the mounting assembly.

[0034] Furthermore, the installation assembly includes an assembly plate 34 connected to the housing 1, and the assembly plate 34 is evenly provided with assembly holes 35 that mate with the ends of the ion air bar 36; the height of the ion air bar 36 can be adjusted by connecting the ion air bar 36 to different assembly holes 35.

[0035] Specifically, by setting up the ion air bar 36 and the mounting components, the assembly plate 34 is connected to the housing 1, and the ion air bar 36 is connected to the assembly hole 35, so that the ion air bar 36 is suspended below the housing 1. Compared with the prior art, the ion air bar 36 outputs an ion air curtain to the composite fibers ejected from the spinneret 33. The charge in the ion air curtain neutralizes the charge accumulated by the composite fiber melt due to friction with the inside of the spinneret 33. On the one hand, it prevents the reduction of fiber diameter uniformity due to electrostatic repulsion between the fiber bundles. On the other hand, it prevents the fibers from adsorbing a large amount of dust in the environment due to static electricity, which would affect the cleanliness of the fibers. In addition, it can also prevent the accumulation of static electricity from causing sparks to be generated by the fiber collection roller, thus improving production safety.
