AI Technical Summary
In the current production of UV-resistant polyamide 6 fibers, the suction pipe structure is open, which leads to uneven suction force and uneven adsorption of grease on the fiber bundle, and the accumulation of waste fibers and other foreign matter, causing pipe blockage.
A filter screen is installed at the end of the suction pipe and fixed by a fixing unit to reduce the air flow area and reduce suction force, ensuring uniform suction force, while preventing waste filaments and other debris from entering the pipe.
This results in more uniform suction, improved grease uniformity, and prevents debris such as waste fibers from entering the pipes, thus avoiding blockages.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of spinning production technology, and in particular to a pre-network suction device for UV-resistant polyamide 6 fibers. Background Technology
[0002] Pre-networkers play a significant role in the production of UV-resistant polyamide 6 fibers or other nylon fibers. They can significantly improve the spinnability of the filament bundle and enhance the yield and quality stability of the finished yarn. The working principle of the pre-networker is to generate a "vortex" in the internal yarn passage zone through a rationally designed yarn path and airflow nozzles. This causes the filament bundle to "oscillate" under the action of airflow, promoting the uniform dispersion of the oil agent on the fiber surface, forming a uniform oil film, and enhancing the cohesion of the filament bundle.
[0003] However, when the filament bundle passes through the pre-networker 100, some grease will be blown out. To absorb this grease, a suction device 200 is installed at the rear of the pre-networker to absorb the blown-out grease, such as... Figure 1 As shown. The existing suction device is an open suction pipe. The inside of the suction pipe is under negative pressure, so that the grease blown out by the pre-filter is drawn into the suction pipe.
[0004] However, because the suction pipe has an open structure, the suction force can be too strong and uneven, easily attracting grease from the yarn bundles and causing uneven oiling. Furthermore, foreign objects such as waste yarn can be drawn into the pipes, accumulating over time and causing blockages and hindering suction. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a pre-network suction device for UV-resistant polyamide 6 fibers, which can make the suction force of the suction pipe more uniform and prevent foreign objects such as waste fibers from being drawn into the pipe.
[0006] This utility model is implemented as follows:
[0007] This utility model provides a pre-network suction device for UV-resistant polyamide 6 fibers, which is disposed on the rear side of the pre-network device. The suction device includes a mounting plate and a suction pipe for suctioning grease. The mounting plate has a mounting hole, and one end of the suction pipe is connected to the mounting hole. A filter assembly is disposed on the side of the mounting plate near the pre-network device. The filter assembly is disposed at the mounting hole and includes a filter screen and a fixing unit for fixing the filter screen.
[0008] Furthermore, the fixing unit includes a fixing frame welded to the mounting plate, the fixing frame having a through hole in the middle that matches the mounting hole, and the fixing frame having a mounting groove on the side near the mounting plate that matches the filter screen, the filter screen being detachably connected in the mounting groove.
[0009] Furthermore, the fixing frame has a threaded hole that communicates with the mounting groove, and a set screw is connected to the threaded hole. The end of the set screw abuts against the side of the filter screen.
[0010] Furthermore, the fixed frame is provided with a lifting groove, the length direction of the lifting groove is vertical, the upper end of the lifting groove extends to the top of the fixed frame, and a lifting screw is provided at the position opposite to the lifting groove of the filter screen, the lifting screw being slidably connected in the lifting groove.
[0011] The advantages of this invention are as follows: by installing a filter screen at the end of the suction pipe, the airflow area is reduced, thus lowering the suction force of the suction device. Furthermore, the filter screen ensures more uniform suction, improving the evenness of oil application. Simultaneously, the filter screen prevents waste fibers and other debris from being drawn into the suction pipe. Attached Figure Description

[0020] Please see Figures 2 to 5 This invention provides a pre-network suction device for UV-resistant polyamide 6 fibers, disposed on the rear side of a pre-network device. The suction device includes a mounting plate 1 and a suction pipe 2 for suctioning grease. The mounting plate 1 has a mounting hole 3, and one end of the suction pipe 2 is connected to the mounting hole 3. A filter assembly 4 is disposed on the side of the mounting plate 1 near the pre-network device, located at the mounting hole 3. The filter assembly 4 includes a filter screen 5 and a fixing unit 6 for fixing the filter screen 5. By placing the filter screen 5 at the end of the suction pipe 2, the airflow area is reduced, thus lowering the suction force of the suction device. Furthermore, the filter screen 5 makes the suction force of the suction device more uniform, improving the uniformity of oil application. Simultaneously, the filter screen 5 also prevents waste fibers and other debris from being drawn into the suction pipe 2.
[0021] Specifically, the fixing unit 6 includes a fixing frame 7 welded to the mounting plate 1. The fixing frame 7 has a through hole 8 in its center that matches the mounting hole 3. The fixing frame 7 also has a mounting groove 9 on its side near the mounting plate 1 that matches the filter screen 5. The filter screen 5 is detachably connected to the mounting groove 9. The mounting groove 9 extends to the top of the fixing frame. When installing the filter screen 5, it slides downwards into the mounting groove. After long-term use, impurities such as monomer crystals will adhere to the filter screen 5; the detachable filter screen 5 facilitates cleaning.
[0022] Specifically, the fixing frame 7 has a threaded hole that communicates with the mounting groove 9. A set screw 10 is connected to the threaded hole, and the end of the set screw 10 abuts against the side of the filter screen 5. The filter screen 5 is firmly fixed in the mounting groove 9 by the set screw 10.
[0023] Specifically, the fixed frame 7 has a lifting groove 11, which extends vertically along its length. The upper end of the lifting groove 11 extends to the top of the fixed frame 7. A lifting screw 12 is provided at the position opposite to the lifting groove 11 on the filter screen 5. The lifting screw 12 is slidably connected in the lifting groove 11. The lifting screw 12 facilitates the removal of the filter screen 5.
