Description

Technical Field

[0001] The present invention belongs to the technical field of ultra-high molecular weight polyethylene fibers, and in particular relates to a cut-resistant ultra-high molecular weight polyethylene fiber and a preparation method and application thereof. Background Art

[0002] Ultra-high molecular weight polyethylene fiber refers to a fiber material spun from polyethylene with a relative molecular weight of more than 1 million. Due to its many advantages such as light weight, impact resistance and high dielectric properties, ultra-high molecular weight polyethylene fiber is widely used in various fields such as aerospace, maritime defense, weapons and equipment, and daily industrial fields.

[0003] In daily industrial fields, ultra-high molecular weight polyethylene fibers are often used to produce cut-resistant products such as ropes and gloves. The cut resistance of ultra-high molecular weight polyethylene fibers prepared only from polyethylene powder is limited. Therefore, in order to improve the cut resistance of ultra-high molecular weight polyethylene fibers, hard components such as glass fibers are usually added to ultra-high molecular weight polyethylene fibers.

[0004] In the prior art, cut-resistant ultra-high molecular weight polyethylene fibers require a spinning solution to be prepared before being drawn and formed. This solution is typically prepared by mixing several raw materials together and then continuously rotating a stirring element to achieve thorough mixing. While this method of preparing the spinning solution can achieve thorough mixing of the raw materials, its efficiency is low. To address this issue, we provide a cut-resistant ultra-high molecular weight polyethylene fiber, a preparation method, and applications thereof to address these issues. Summary of the Invention

[0005] The object of the present invention is to provide a cut-resistant ultra-high molecular weight polyethylene fiber and its preparation method and application. Through the specific structural design of the carrying mechanism, the first storage mechanism, the second storage mechanism, the intermittent feeding mechanism, the mixing control mechanism, the mixing power component and the cloth component, the problem of the traditional preparation of spinning solution, which is generally to mix several raw materials together and achieve sufficient mixing of various raw materials through the continuous rotation of the stirring component, thereby preparing the spinning solution, is solved.

[0043] S02. During the rotation of the rotating distribution disc 803, the solid raw materials are dispersed into the corresponding first mixing box 302 through the rotation of each distribution component 9 on the rotating distribution disc 803. The first auger rotating synchronously with the rotating distribution disc 803 transports the solvent oil in the storage tank 802 to the first mixing box 302 to achieve sufficient mixing with the solid raw materials;

[0045] S04. The prepared spinning solution is sequentially spun, pre-stretched, extracted, dried, and drawn, thereby obtaining cut-resistant ultra-high molecular weight polyethylene fibers.

[0046] In this embodiment of the present invention, the first mixing structure 1 and the second mixing structure 2 are both installed on a carrying mechanism 3; wherein the carrying mechanism 3 includes a carrying frame 301, a first mixing box 302 is symmetrically installed at the top of the carrying frame 301, and a second mixing box 303 is installed at the bottom of the carrying frame 301. A withdrawal pump 304 is installed at the bottom of the carrying frame 301, and a withdrawal pipe connected to the liquid inlet of the withdrawal pump 304 is connected to the second mixing box 303. The second mixing box 303 and the first mixing boxes 302 on both sides are connected by gravity pipes 305. A control valve 306 close to the bottom of the first mixing box 302 is installed on the gravity pipe 305. Figure 1 As shown, after the first mixed solution is prepared by the first mixing box 302 on the left and the second mixed solution is prepared by the first mixing box 302 on the right, the two control valves 306 on the left and right sides are opened at the same time, so that the first mixed solution and the second mixed solution flow into the second mixing box 303 at the same time to be mixed again.

[0047] In this embodiment of the present invention, a first rotating shaft is rotatably mounted on the supporting frame 301, and a first gear 307 and a transmission wheel 308 are fixedly mounted on the circumferential side of the first rotating shaft. The two transmission wheels 308 are connected by a transmission belt 309. The output end of the material distribution control motor 310 installed on the top of the supporting frame 301 is connected to the corresponding first rotating shaft, and a copper powder discharge port 311 connected to the inner cavity of the second mixing box 303 is installed on the top of the second mixing box. A material distribution channel 312 installed above the copper powder discharge port 311 is connected to the copper powder storage pipe 313 (the material distribution channel 312 is arranged obliquely and its bottom is a sieve structure). After starting the material distribution control motor 310, the synchronous rotation of the two first gears 307 can be achieved through the cooperation of the transmission belt 309 and the transmission wheel 308, thereby driving the rotating material distribution disk 803 on the first mixing structure 1 and the rotating material distribution disk 803 on the second mixing structure 2 to rotate synchronously.

An inner gear ring 314 is rotatably mounted inside the second mixing box 303. A plurality of first mixing components 315 are arranged in a circumferential array at the bottom of the inner gear ring 314. A second gear connected to the corresponding first rotating shaft is meshed on the inner wall of the inner gear ring 314.

After opening the two control valves 306 on the left and right sides, the first mixed solution and the second mixed solution flow into the second mixing box 303 at the same time. In this process, the corresponding first gear 307 is controlled to rotate by the material distribution control motor 310, and the transmission belt 309 and the transmission wheel 308 are connected. The two first gears 307 rotate synchronously with the cooperation of the two first gears 307, and the second gear rotating synchronously with the first shaft drives the inner gear ring 314 to rotate, and then the inner gear ring 314 drives the third gear to rotate synchronously, thereby causing the first mixing component 315 rotating synchronously with the inner gear ring 314 to rotate. During the rotation of the inner gear ring 314, it drives the second auger to rotate inside the copper powder storage tube 313. Through the rotation of the second auger, the copper powder in the copper powder storage tube 313 is gradually transported and dispersed into the second mixing box 303, thereby achieving sufficient mixing between the copper powder, the first mixed solution and the second mixed solution, and finally preparing the spinning solution. Subsequently, the extraction pump 304 is turned on to extract the spinning solution and transport it to the back-end process for further processing.

[0049] In this embodiment of the present invention, the first mixing structure 1 includes a first storage mechanism 4, and the second mixing structure 2 includes a second storage mechanism 5; wherein, the first storage mechanism 4 and the second storage mechanism 5 both include an annular mounting frame 401 fixedly mounted on the top of the carrying frame 301, the annular mounting frame 401 is coaxially arranged with the corresponding first mixing box 302, and a plurality of arc-shaped bevel gear portions 402 are arranged in a circumferential array on the inner wall of the annular mounting frame 401, a gear mounting opening 403 is opened on the outer wall of the annular mounting frame 401, and a bevel gear ring 404 coaxial with it is arranged inside the annular mounting frame 401, a bulk material channel 405 is installed on the inner wall of the annular mounting frame 401 on the first storage mechanism 4, and two bulk material channels 405 are symmetrically installed on the inner wall of the annular mounting frame 401 on the second storage mechanism 5, and the storage box 406 is fixedly mounted on the top of the corresponding bulk material channel 405.

In the initial state, the intermittent feeding port 602 on the intermittent feeding pipe 601 is upright and facing downwards, at which time the discharge port at the bottom of the storage box 406 is blocked by the intermittent feeding pipe 601, and the required number of ultra-high molecular weight polyethylene fibers, ceramic fibers and alumina whiskers are placed in the corresponding storage boxes respectively. 406, and then place the required capacity of solvent oil in the storage tank 802, and then in the process of controlling the synchronous rotation of the rotating distribution discs 803 on both sides on the left side, the bevel gear ring 404 that rotates synchronously with the rotating distribution disc 803 drives the first bevel gear 603 to rotate, and when the intermittent discharge port 602 rotates to achieve communication with the corresponding storage box 406, the raw materials in the storage box 406 enter the intermittent discharge pipe 601 along the intermittent discharge port 602, and when the intermittent discharge port 602 is downward again to achieve communication with the discharge port at the bottom of the bulk channel 405, the raw materials in the intermittent discharge pipe 601 are gradually dispersed into the rotating rotating distribution disc 803.

[0051] Specific embodiment 2, on the basis of specific embodiment 1, the first mixing structure 1 and the second mixing structure 2 both further include a mixing control mechanism 7; wherein, the mixing control mechanism 7 includes a mixing power assembly 8; the mixing power assembly 8 includes a mixing support frame 801 fixedly mounted on the annular mounting frame 401, a storage tank 802 fixedly mounted inside the mixing support frame 801, a rotating distribution disc 803 rotatably engaged with the inner bottom of the annular mounting frame 401, an outer gear ring 804 is fixedly mounted on the peripheral side of the rotating distribution disc 803, a first gear 307 is arranged inside the gear mounting port 403 and meshes with the outer gear ring 804, through this structural design, when the first gear 307 is controlled to rotate, the synchronous rotation of the outer gear ring 804 can be achieved, and the rotating distribution disc 803 is driven to rotate by the outer gear ring 804.

[0052] In this embodiment of the present invention, a vertical linkage rod 805 is fixedly provided at the bottom of the rotating distribution disk 803, and a horizontal support portion 806 is fixedly installed at the bottom of the vertical linkage rod 805. A scraper 807 that is in contact with the inner wall of the first mixing box 302 is symmetrically fixedly installed on the top of the horizontal support portion 806, and a second mixing component 808 is fixedly installed on one side of the scraper 807. In the process of controlling the synchronous rotation of the rotating distribution disks 803 on the left and right sides, the vertical linkage rod 805 that rotates synchronously with the rotating distribution disk 803 drives the scraper 807 and the second mixing component 808 to rotate, and the scraper 807 is used to slide along the inner wall of the first mixing box 302 to scrape off the attached materials, and then cooperate with the rotation of the second mixing component 808 to fully mix the raw materials and the solvent oil, thereby preparing the first mixed solution and the second mixed solution. The coaxial center separating ring 809 and the bevel gear ring 404 are fixedly mounted on the top of the center separating ring 809. The bottom of the rotating distribution disk 803 is provided with a flow port 810 located on the inner side of the center separating ring 809. The bottom of the storage tank 802 is connected to a guide pipe 811 extending to the inside of the center separating ring 809. The first auger is arranged inside the guide pipe 811 and is fixedly connected to the rotating distribution disk 803. Through the rotation of the first auger, the solvent oil in the storage tank 802 is gradually transported to the inside of the center separating ring 809 along the guide pipe 811. The solvent oil flowing into the inside of the center separating ring 809 flows downward along each flow port 810 into the corresponding first mixing box 302. The solvent oil flowing into the first mixing box 302 is fully mixed with the powdered or granular raw material dispersed therein, thereby preparing a first mixed solution and a second mixed solution.

[0053] In this embodiment of the present invention, a plurality of material distribution installation openings 812 are provided in an annular array inside the rotating material distribution disk 803, and a plurality of inclined material guide platforms 813 are provided in an annular array inside the rotating material distribution disk 803. In the process of controlling the synchronous rotation of the rotating material distribution disks 803 on both sides on the left side, the bevel gear ring 404 that rotates synchronously with the rotating material distribution disk 803 drives the first bevel gear 603 to rotate. When the intermittent discharge port 602 rotates to connect with the corresponding storage box 406, the raw materials in the storage box 406 enter the intermittent discharge pipe 601 along the intermittent discharge port 602. When the intermittent discharge port 602 is downward again to connect with the discharge port at the bottom of the bulk material channel 405, the raw materials in the intermittent discharge pipe 601 are The raw materials are gradually dispersed into the rotating feeding disk 803 in a rotating state. In this process, the raw materials that fall onto the various inclined guide platforms 813 slide down along the smooth inclined surface and gather at each feeding installation port 812. The feeding port 812 is arranged between two adjacent inclined guide platforms 813; the feeding assembly 9 includes a second rotating shaft connected to the corresponding feeding installation port 812 through a torsion spring, and a feeding flip plate 901 located inside the feeding installation port 812 is fixedly installed on the second rotating shaft. The second rotating shaft passes through the end of the rotating feeding disk 803 and is fixed with a second bevel gear 902 that is adapted to the arc-shaped bevel tooth portion 402. In the initial state, the feeding flip plate 901 is horizontally arranged inside the corresponding feeding installation port 812.

[0054] After placing the required amount of ultra-high molecular weight polyethylene fibers, ceramic fibers, and alumina whiskers in the corresponding storage boxes 406, the required amount of solvent oil is placed in the storage tank 802. At the same time, the required amount of copper powder (iron powder can also be used) is placed in the copper powder storage tube 313. Then, the material distribution control motor 310 is started to control the synchronous rotation of the rotating material distribution discs 803 on the left and right sides. During the process of controlling the synchronous rotation of the rotating material distribution discs 803 on the left and right sides, the bevel gear ring 404 that rotates synchronously with the rotating material distribution disc 803 drives the first bevel gear 603 to rotate. When the intermittent discharge port 602 rotates to connect with the corresponding storage box 406, the raw materials in the storage box 406 enter the intermittent discharge pipe 601 along the intermittent discharge port 602. When the intermittent discharge port 602 is downward again to connect with the discharge port at the bottom of the bulk channel 405, the raw materials in the intermittent discharge pipe 601 are gradually dispersed into the rotating distribution plate 803 in a rotating state. In this process, the raw materials that fall onto each inclined guide platform 813 slide along the smooth inclined surface and gather at each distribution installation port 812 (i.e., the position of the distribution flip plate 901).

[0055] In the process of controlling the synchronous rotation of the rotating distribution discs 803 on the left and right sides, when each second bevel gear 902 contacts the arc-shaped bevel tooth portion 402 at the corresponding position and rolls along it, it can drive the circumferentially arranged distribution flip plates 901 to rotate a certain angle, thereby allowing the solid raw materials on each distribution flip plate 901 to slide through the distribution installation port 812 and be dispersed into the first mixing box 302. When the second bevel gear 902 disengages from the arc-shaped bevel tooth portion 402, the elastic force of the torsion spring can be used to reverse and reset each distribution flip plate 901 to a horizontal state. In this way, the intermittent flipping and blanking of each distribution flip plate 901 can be achieved, thereby allowing the solid raw materials to be intermittently dispersed into the first mixing box 302. At the same time, while controlling the synchronous rotation of the rotating distribution discs 803 on the left and right sides, During the process, the rotation of the first auger causes the solvent oil in the storage tank 802 to be gradually transported to the inner side of the central separating ring 809 along the guide pipe 811, and the solvent oil flowing into the inner side of the central separating ring 809 flows downward along each flow port 810 into the corresponding first mixing box 302, and the solvent oil flowing into the first mixing box 302 is fully mixed with the powdered or granular raw materials dispersed therein. The vertical linkage rod 805 that rotates synchronously with the rotating distribution disk 803 drives the scraper plate 807 and the second mixing component 808 to rotate, and the scraper plate 807 slides along the inner wall of the first mixing box 302 to scrape off the attached materials, and then cooperates with the rotation of the second mixing component 808 to achieve full mixing of the raw materials and the solvent oil, thereby preparing the first mixed solution and the second mixed solution.

[0056] After the preparation of the first mixed solution and the second mixed solution is completed, the two control valves 306 on the left and right sides are opened, and the first mixed solution and the second mixed solution flow into the second mixing box 303 at the same time. In this process, the corresponding first gear 307 is controlled by the material distribution control motor 310 to rotate, and the two first gears 307 are rotated synchronously under the cooperation of the transmission belt 309 and the transmission wheel 308. The second gear rotating synchronously with the first shaft drives the inner gear ring 314 to rotate, and the inner gear ring 314 drives the third gear to rotate. The inner gear ring 314 rotates synchronously, thereby causing the first mixing component 315 that rotates synchronously with the inner gear ring 314 to rotate. During the rotation of the inner gear ring 314, it drives the second auger to rotate inside the copper powder storage tube 313. Through the rotation of the second auger, the copper powder in the copper powder storage tube 313 is gradually transported and dispersed into the second mixing box 303, thereby achieving sufficient mixing between the copper powder, the first mixed solution and the second mixed solution, and finally preparing the spinning solution. Subsequently, the extraction pump 304 is turned on to extract the spinning solution and transport it to the back-end process for further processing.
