Description

Technical Field

[0001] This utility model belongs to the field of fiber spinning technology. Specifically, this utility model relates to an oil removal device for ultra-high molecular weight polyethylene fiber gel filaments. Background Technology

[0002] Ultra-high molecular weight polyethylene (UHMWPE) fiber, with its excellent physical properties such as extremely high strength, abrasion resistance, and chemical stability, has been widely used in various industrial fields, including bulletproof vests, high-performance ropes, sporting goods, and composite materials. Currently, the mainstream production process for this fiber is wet spinning technology.

[0003] In the wet spinning process, ultra-high molecular weight polyethylene powder is first mixed with a suitable solvent. Through heating and stirring, the polyethylene powder is completely dissolved in the solvent, forming a homogeneous polymer solution. This step is crucial for ensuring the smooth progress of subsequent spinning processes and the stability of fiber properties.

[0004] Next, the polymer solution is fed into a spinning device and extruded as a continuous fine stream through a precisely designed spinneret. The extruded solution stream is then placed in a low-temperature water bath environment—a process known as rapid cooling. In the water bath, the polymer chains rapidly solidify, forming what is called "gelatin filaments." Rapid cooling helps maintain the fineness and uniformity of the fibers and has a significant impact on the final physical properties of the fibers.

[0005] After being removed from the water bath, the gel filaments are collected in a holding tank. In this tank, the gel filaments undergo a prolonged settling and equilibration process to allow residual solvent and moisture to drain from the fibers. This step is crucial for reducing fiber porosity and increasing fiber density and strength, but it is also the most time-consuming part of the entire production process. The extended settling and equilibration period not only increases production costs but also limits the rate of production.

[0006] For example, Chinese Patent Application No. 201610180675.8 discloses a wire holding bucket with a movable frame, including a wire holding bucket, a movable frame, handles, rotating frames and rollers. The wire holding bucket is welded into the movable frame by welding. The movable frame has at least 3-4 handles on the outer side of the middle part. The movable frame has at least 3 rotating frames at the bottom. The rollers are fixedly installed in the corresponding rotating frames by rotating shafts.

[0007] The aim is to provide an oil drainage device for ultra-high molecular weight polyethylene fiber gel filaments, particularly regarding how to shorten the time required for oil and water drainage from the gel filaments, reduce time costs, and increase production rate. Utility Model Content

[0028] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of this utility model, and to facilitate its implementation.

[0029] It should be noted that in the following embodiments, the terms "first" and "second" do not represent an absolute distinction in structure and / or function, nor do they represent the order of execution, but are merely for the convenience of description.

[0030] like Figures 1 to 7 As shown, this utility model provides an oil draining device for ultra-high molecular weight polyethylene fiber gel filaments, including a box body 2, a partition 8 disposed in the box body 2, and a rotating shaft 7 rotatably disposed and passing through the partition 8. Multiple partitions 8 are provided, and a receiving cavity for accommodating gel filaments is formed between two adjacent partitions 8. The rotating shaft 7 is configured to wind the gel filaments located in the receiving cavity and drive the gel filaments to rotate after winding.

[0031] Specifically, such as Figure 1As shown, the housing 2 has a hollow internal structure. The axis of the rotating shaft 7 is parallel to a first direction, which is horizontal. All partitions 8 are arranged sequentially and equidistantly along the axial direction of the rotating shaft 7. The partitions 8 are vertically arranged. Each accommodating cavity is a rectangular cavity formed by two adjacent partitions 8 and the inner wall of the housing 2. Through holes are provided on the partitions 8, which are through holes extending along the thickness direction of the partitions 8. A first bearing 4 is installed in the through hole and is sleeved on the rotating shaft 7. The rotating shaft 7 is mounted on the housing 2 through two second bearings 5, and all partitions 8 are located between the two second bearings 5. The rotating shaft 7 is connected to a drive mechanism located outside the housing 2. The drive mechanism is used to drive the rotating shaft 7 to rotate around its axis.

[0032] like Figure 1 As shown in this embodiment of the invention, the partition 8 divides the internal space of the housing 2 into several areas. A rotating shaft 7 is located inside the housing 2, passing through the partition 8. During winding, the gel filaments are wound onto the rotating shaft 7, and the shaft is started to wind them. After winding, the rotating shaft 7 is controlled to rotate at high speed, using centrifugal force to discharge the white oil and water from the inside and outside of the gel filaments, completing the oil removal process. During discharge, the rotating shaft 7 is reversed to discharge the filaments. This oil removal device can greatly shorten the time required for oil and water removal from the gel filaments, reduce time costs, and increase production speed.

[0033] like Figure 1 As shown in the embodiment of this utility model, the driving mechanism mainly includes a drive motor 3. The output end of the drive motor 3 is fixedly connected to one end of the rotating shaft 7. The drive motor 3 is fixedly installed on the housing 2.

[0034] like Figure 3 and Figure 5 As shown in this embodiment of the invention, a pin 9 is provided on the first bearing 4, and a socket is provided on the partition plate 8 for inserting the pin 9. The pin 9 is fixedly mounted on the outer ring of the first bearing 4, extending upward toward the outside of the outer ring. The pin 9 is vertically positioned, and the socket extends upward toward the inside of the partition plate 8 from the inner circular surface of the through hole. By inserting the pin 9 into the socket, the partition plate 8 can be fixed. This structure can fix the outer ring of the first bearing 4 to the partition plate 8, preventing the outer ring of the first bearing 4 from rotating, thus preventing friction between the outer ring and the partition plate 8 and reducing wear on the partition plate 8.

[0035] like Figure 3As shown in this embodiment of the invention, a slot 17 is provided on the inner wall of the box 2. The edge of the partition 8 is embedded in the slot 17. The slot 17 is used to position the partition 8 within the box 2. Multiple slots 17 are provided. The slot 17 extends downward from the top surface of the box 2, forming an opening on the top surface of the box 2. The partition 8 can be pulled out from the slot 17 and separated from the box 2. The number of gel fibers varies in different production processes. Multiple slots 17 can be used to insert the corresponding partition 8 according to the number of gel fibers, making the number of partitions 8 adjustable.

[0036] like Figure 2 and Figure 3 As shown in the embodiment of this utility model, an opening is provided on the partition 8. The opening extends upward from the bottom surface of the partition 8 to the through hole. The opening is a through hole that extends along the thickness direction of the partition 8 and is triangular in shape.

[0037] like Figure 6 As shown in the embodiment of this utility model, a first handle 13 is provided on the outer wall of the box body 2, and a box cover 6 is provided on the top of the box body 2. The box cover 6 is used to control the opening and closing of the opening provided on the top of the box body 2. The box cover 6 is rotatably connected to the box body 2, and a second handle 14 is provided on the box cover 6.

[0038] like Figure 1 As shown in this embodiment of the utility model, the bottom plate of the box 2 is provided with casters 1, and a total of four casters 1 are provided.

[0039] like Figure 1 and Figure 7 As shown in this embodiment of the invention, a filter device is installed inside the housing 2, located below the partition 8. The filter device mainly includes a filter screen 10. An oil drain port 11 is located at the bottom of the housing 2, and a valve 12 is installed at the oil drain port 11 to control the opening and closing of the oil drain port 11. The oil drain port 11 is located below the filter screen 10, which is horizontally positioned. The filter screen 10 is used to filter the oil falling from the upper accommodating cavity, and the filtered oil enters the lower oil storage cavity. The filtered oil can be recycled and reused, reducing production costs. The filter screen 10 prevents the gel fibers from immersing in the oil.

[0040] like Figure 1 and Figure 7As shown in this embodiment of the utility model, an oil storage chamber is provided inside the housing 2. The oil storage chamber is located below the filter screen 10 and is connected to the oil drain port 11. The inner wall of the oil storage chamber is inclined and is formed by multiple inner wall surfaces. The inner wall of the oil storage chamber extends inclinedly from the upper end to the lower end. The distance between the upper ends of two opposite inner wall surfaces in the oil storage chamber is greater than the distance between the lower ends. The inner wall of the oil storage chamber is used to guide the oil to flow towards the lower oil drain port 11, which facilitates the collection of the oil and allows the oil to be discharged from the oil drain port 11 at a faster speed.

[0041] like Figure 7 As shown in this embodiment of the invention, a control panel 16 is provided on the housing 2. The control panel 16 is connected to a control system, which is connected to a frequency converter 15. The frequency converter 15 is connected to a drive motor 3. When the filament is being fed, the rotation speed is set on the control panel 16. The control system receives the setting and transmits it to the frequency converter 15. The frequency converter 15 controls the rotation speed and direction of the drive motor 3, ensuring that the speed at which the gel filament is wound on the rotating shaft 7 is equal to the speed at which it is unwound. When draining oil, the rotation speed is increased, and the rotation direction is the same as when the filament is being wound. When discharging filament, the drive motor 3 is rotated in the opposite direction, and the rotation speed is adjusted to ensure normal and stable filament discharge.

[0042] The method of using the above-described ultra-high molecular weight polyethylene fiber gel filament oil removal device includes the following steps:

[0043] S1. Place the gelatin filaments into the accommodating cavity and wind the gelatin filaments onto the rotating shaft 7;

[0044] S2, the rotating shaft 7 rotates to collect the gel filaments;

[0045] S3. The rotating shaft 7 drives the gel filament to rotate, and the rotation direction of the rotating shaft 7 is the same as the rotation direction in step S2.

[0046] S4. The yarn is produced. The rotating shaft 7 rotates in the opposite direction to the rotation direction in step S3.

[0047] In step S1 above, firstly, according to the number of gel fibers, the corresponding partitions 8 are inserted into the box 2 to divide the space inside the box 2 into several areas of the same size. Each accommodating cavity contains only one gel fiber, and the operator manually winds the gel fiber onto the rotating shaft 7.

[0048] In step S2 above, the drive mechanism drives the rotating shaft 7 to rotate around the axis at a first set speed to take in the gel filaments, and after the filaments fall off, the take-in speed and the fall-off speed are kept consistent.

[0049] In step S3 above, after the wire dropping is completed, the box cover 6 is closed, sealing the top opening of the box 2. The valve 12 is then opened, and the drive mechanism drives the rotating shaft 7 to rotate around its axis at a second set speed. At this time, the rotation direction of the rotating shaft 7 is the same as in step S2, and the second set speed is greater than the first set speed. The second set speed is generally set to between 600 r / min and 1200 r / min.

[0050] In step S3 above, after the rotating shaft 7 drives the gel fiber to rotate for a set time, most of the white oil and water contained in the gel fiber are discharged, and the oil enters the oil storage chamber at the bottom of the box 2.

[0051] In step S4 above, when the filament is being extruded, the box cover 6 is opened, the end of the gel filament is tied to the previous gel filament, and then the drive mechanism drives the rotating shaft 7 to rotate around the axis. At this time, the rotation direction of the rotating shaft 7 is opposite to the rotation direction in step S3. The rotating shaft 7 rotates in the opposite direction to extrude the filament, and the gel filament wound on the rotating shaft 7 is released.

[0052] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
