Description

Technical Field

[0001] The utility model relates to the technical field of fiber wet spinning equipment, in particular to a water-soluble fiber washing and oiling device. Background Art

[0002] Vinylon, also known as vinylon, is a synthetic fiber manufactured using polyvinyl alcohol as raw material and water as solvent through wet spinning. It has a wide range of uses, and its main varieties include water-soluble vinylon staple fiber, water-soluble vinylon filament, acetalized vinylon staple fiber, and acetalized vinylon filament. As an emerging vinylon fiber, the production process of water-soluble vinylon filament includes spinning heat treatment and post-processing stages. Spinning heat treatment mainly refers to the production of semi-finished filament bundles, including spinning, coagulation and dehydration, guide roller drawing, bundling, wet heat drawing, drying, preheating, extension, shrinkage heat setting, cooling, winding and other steps. After the above spinning and heat treatment process, the fiber has a certain strength, elongation, and hot water resistance. However, the filament bundle also contains a high level of Glauber's salt, and the fiber does not contain oil and fat, so it cannot be sold or used directly and can only be called a semi-finished product.

[0003] At present, the washing section of the post-processing device is usually used to wash and reduce the sodium sulfate in the tow, and the oiling section is used to grease the fiber. A post-processing device used by our company is mainly composed of a hydroformylation machine and a dryer. The washing section and oiling section of the hydroformylation machine are used to wash and oil the fiber (the hydroformylation section is only used during hydroformylation), and the dryer is used to dry the fiber. However, since the main function of the hydroformylation machine is to acetalize the fibers, most of the Glauber's salt in the fibers is washed out during the acetalization, and a small amount of Glauber's salt in the fibers is washed out in the water washing section. Therefore, when using the existing post-processing device (hydroformylation machine) to process the semi-finished filament bundles, if only the water washing section is used for washing, the water washing time of the filament bundles is insufficient, which is not conducive to the removal of the Glauber's salt. If the Glauber's salt is not washed well, it will remain on the filament bundles and crystallize, which will cause the filament bundles to stick together and affect the dispersion of the product. If the acetalization section is also used for water washing, the hydroformylation liquid in the hydroformylation section needs to be extracted first and replaced with a water washing liquid. The operation is cumbersome, and the solution needs to be replaced again when other types of filament bundles are subsequently produced, resulting in reduced production efficiency. Utility Model Content

[0004] The utility model provides a water-soluble fiber washing and oiling device, which can solve the technical problem that the existing post-processing device has poor processing effect when processing filament bundle semi-finished products, resulting in poor fiber dispersion.

[0005] This application provides the following technical solutions:

[0006] The water-soluble fiber washing and oiling device includes a washing tank, in which several groups of kneading components are arranged. The kneading components include a wire supporting rod and a wire pressing rod. The wire supporting rod is fixedly arranged in the washing tank, and the wire bundle passes through the upper surface of the wire supporting rod. The wire pressing rod is arranged in the washing tank through a lifting component, and the wire bundle passes through the lower surface of the wire pressing rod.

[0007] Technical principles and beneficial effects:

[0008] When in use, the position of the screw supporting rod is fixed, and the screw pressing rod is driven to move up and down by the lifting assembly. By adjusting the up and down positions of the screw pressing rod, the yarn bundle is kept at a certain immersion depth; when the position of the screw pressing rod is lower than the screw supporting rod, the naturally narrowed yarn bundle will expand to both sides under the downward pressure of the screw pressing rod, thereby widening the yarn bundle, and the width increases with the increase of the vertical distance between the screw pressing rod and the screw supporting rod; under the action of multiple groups of screw supporting rods and screw pressing rods, the yarn bundle is alternately changed in width, which has a certain "kneading" effect on the yarn bundle, which is beneficial to the washing of Glauber's salt in the fiber; in addition, compared with always being in one state, the yarn bundle alternately changing in width is beneficial to improving the dispersion between fiber bundles, reducing the sticking of yarn bundles, and thus improving product quality.

[0009] Furthermore, the lifting assembly includes a lifting rod and a mounting seat arranged at the bottom of the lifting rod, the end of the screw rod is connected to the mounting seat, and slide grooves are provided on the two opposite side walls of the washing tank, and the mounting seat is slidably arranged in the slide grooves.

[0010] Beneficial effect: The mounting seat is driven to slide up and down in the slide groove by the lifting rod, thereby driving the screw rod to move up and down, which is used to adjust the immersion depth of the wire bundle. The setting of the slide groove is conducive to ensuring that the screw rod moves stably in the washing liquid.

[0011] Furthermore, at least two groups of water washing tanks are provided, and the multiple groups of water washing tanks are arranged in layers along the vertical direction. Wire guides are provided between adjacent water washing tanks, and each wire guide is independently driven.

[0012] Beneficial effects: Multiple groups of water washing tanks are arranged in the vertical direction to make full use of the vertical space, which is conducive to reducing the occupation of horizontal space. Multiple groups of wire guides are independently driven, and the wire guides can be controlled individually to adjust the tightness of the wire bundle during operation.

[0013] Furthermore, it also includes a supporting platform, and a water washing tank is arranged on the supporting platform. There are two groups of water washing tanks, including a first water washing tank and a second water washing tank from top to bottom; a wire guide machine is arranged on the supporting platform, including a first wire guide machine, a second wire guide machine, and a third wire guide machine. The first wire guide machine is located in front of the first water washing tank, the second wire guide machine is arranged between the first water washing tank and the second water washing tank, and the third wire guide machine is arranged at the outlet of the second water washing tank.

[0014] Beneficial effect: The first wire guide machine is used to feed the front end of the wire bundle into the first water washing tank. After the first water washing, the wire bundle enters the second water washing tank under the traction of the second wire guide machine, and then enters the back-end processing equipment under the traction of the third wire guide machine.

[0015] Furthermore, an oiling device is provided below the supporting platform, and the oiling device is a wet heat drawing machine.

[0016] Beneficial effect: Using the wet heat traction machine as an oiling machine can achieve multiple uses of one machine, which is beneficial to saving equipment and reducing equipment purchase costs.

[0017] Furthermore, an oil inlet pipe and an oil return pipe are provided at the bottom of the wet hot drawing machine, a wire pressing guide rod is provided inside the wet hot drawing machine, and the wire bundle passes through the lower surface of the wire pressing guide rod. A liquid pressing guide rod is also provided at the end of the wet hot drawing machine.

[0018] Beneficial effect: The washed tow is oiled in a wet hot drawing machine. After the oiling is completed, the excess oil is squeezed out by a squeeze guide rod at the end, and then enters the back-end processing equipment.

[0019] Furthermore, a tension frame is provided on the support platform, and the tension frame is located at the front end of the first wire guide machine.

[0020] Beneficial effect: The yarn bundle fed in from the front end is smoothed by the tension frame and fed into the first yarn guide machine after being given a certain tension.

[0021] Furthermore, it also includes a drying device, which is located at the rear end of the oiling device.

[0022] Beneficial effects: The drying equipment is used to dry the oiled tow.

[0023] Furthermore, the drying equipment includes a first dryer, a second dryer and a third dryer arranged in sequence.

[0024] Beneficial effects: Multiple dryers are used to dry the filaments in sections. Compared with the existing method of drying them once in one dryer, the present invention has a longer drying time, better drying effect, and more uniform drying, which is beneficial to further improve the dispersion of the fibers and improve product quality.

[0025] Furthermore, the first dryer is a dryer in the spinning equipment, the second dryer is a preheater in the spinning equipment, and the third dryer is a stretching machine in the spinning equipment; the spinning equipment includes a spinning machine, a guide roller drawing machine, a bundling machine, a wet heat drawing machine, a dryer, a preheater, and a stretching machine arranged in sequence from front to back, and the support platform is arranged above the wet heat drawing machine.

[0026] Beneficial effects: By setting a supporting platform on the spinning equipment production line, setting a water washing tank on the supporting platform, and using the wet hot drawing machine of the spinning equipment as the oiling machine, the dryer, preheating machine, and stretching machine as the first dryer, the second dryer, and the third dryer respectively, the existing equipment is converted, and the dispersion of the fiber is improved during the washing and drying process, thereby improving the product quality.

[0037] Example 1

[0038] like Figure 1 As shown, the water-soluble fiber washing and oiling device includes a washing tank 1, in which several groups of kneading components 2 are arranged. The kneading components 2 include a wire supporting rod 22 and a wire pressing rod 21. The wire supporting rod 22 is fixedly arranged in the washing tank 1, and the yarn bundle 100 passes through the upper surface of the wire supporting rod 22. The wire pressing rod 21 is adjustably arranged in the washing tank 1 through a lifting component, and the yarn bundle 100 passes through the lower surface of the wire pressing rod 21.

[0039] like Figure 2-3 As shown, in this embodiment, the support rod 22 and the pressure rod 21 are both glass guide rods, and the glass guide rods are arranged along the width direction of the water washing tank 1; specifically, the two opposite side walls of the water washing tank 1 are connected with a mounting seat 212 by bolts, and the mounting seat 212 is provided with a mounting groove, and the two ends of the support rod 22 extend into the mounting groove and are clamped or tensioned with the mounting groove.

[0040] The lifting assembly includes a lifting rod 211 and a mounting seat 212 connected to the bottom of the lifting rod 211. The mounting seat 212 is also provided with a mounting groove, and the two ends of the pressing rod 21 are extended into the mounting groove for fixation; in this embodiment, in order to guide and limit the pressing rod 21, vertical slide grooves 213 are provided on the two opposite side walls of the washing tank 1, and the mounting seat 212 is slidably set in the slide groove 213; or a vertical guide rail is provided on the inner wall of the washing tank 1, and a slide groove 213 is provided on the vertical guide rail, and the mounting seat 212 is slidably set in the slide groove 213. Under the lifting action of the lifting rod 211, the pressing rod 21 is driven to move up and down in the slide groove 213. The latter is preferred in this embodiment.

[0041] Specific examples Figure 4-5As shown, the lifting rod 211 in this embodiment adopts a cap-shaped square head bolt, the bottom of the bolt is cap-shaped, and is rotatably set on the top of the mounting seat 212, so that the lifting rod 211 can rotate relative to the mounting seat 212; the upper and middle ends of the lifting rod 211 are provided with threads, and the top of the vertical guide rail is fixed with a mounting plate 2110 by bolts, and the lifting rod 211 is threadedly connected to the mounting plate 2110. Specifically, the top of the lifting rod 211 is a square head, which is convenient for using a wrench to rotate the lifting rod 211, thereby adjusting the height of the screw rod 212.

[0042] When in use, use a wrench to rotate the square head of the lifting rod 211, and the lifting rod 211 moves up and down, thereby driving the mounting seat 212 and the pressing rod 21 to move up and down, and by adjusting the up and down position of the pressing rod 21, the silk bundle 100 maintains a certain immersion depth; when the position of the pressing rod 21 is lower than the screw supporting rod 22, the naturally narrowed silk bundle 100 expands to both sides under the downward pressure of the pressing rod 21, thereby making the silk bundle 100 wider, and the width increases with the increase of the vertical distance between the pressing rod 21 and the screw supporting rod 22; under the action of multiple groups of screw supporting rods 22 and the pressing rod 21, the silk bundle 100 alternates in width and narrowness, which has a certain "kneading" effect on the silk bundle 100, thereby facilitating the washing of the sodium sulfate in the fiber and improving the cleaning efficiency and cleaning effect; in addition, compared with always being in one state (such as natural narrowing), the alternating width and narrowness of the silk bundle 100 is conducive to improving the dispersion between the fiber bundles 100, reducing the sticking of the silk bundle 100, and thus improving product quality.

[0043] Example 2

[0044] The difference between this embodiment and the first embodiment is that the washing tank 1 in the first embodiment is set on the spinning equipment production line, and part of the equipment in the spinning production line is used to post-process the semi-finished tow 100. Figure 6 As shown, the spinning equipment includes a first-unit spinning machine 101, a first-unit guide roller drawing machine 1010, a second-unit spinning machine 102, a second-unit guide roller drawing machine 1020, a bundling machine 103, a wet heat drawing machine 104, a dryer 105, a preheating machine 106, a stretching machine 107, a first shrinking machine 108, a second shrinking machine 109, a cooling machine 110, a traction machine, and a winding machine 111, which are arranged in sequence.

[0045] like Figure 7As shown, in this embodiment, the water washing tank 1 is arranged above the bunching machine 103, the wet hot drawing machine 104 and the drying machine 105, and at least two groups of water washing tanks 1 are arranged, and multiple groups of water washing tanks 1 are arranged in layers along the vertical direction. A wire guide machine is arranged between adjacent water washing tanks 1, and each wire guide machine is independently driven; specifically, it also includes a support platform 3, and the water washing tank 1 is arranged on the support platform 3. Two groups of water washing tanks 1 are arranged, including a first water washing tank 11 and a second water washing tank 12 from top to bottom; in this embodiment, three groups of kneading components 2 are provided in the first water washing tank 11 and the second water washing tank 12, and each group of kneading components 2 is arranged in the order of a wire supporting rod 22, a wire pressing rod 21, and a wire supporting rod 22.

[0046] The wire guide machine is also arranged on the support platform 3. In this embodiment, three groups of wire guide machines are arranged, namely the first wire guide machine 41, the second wire guide machine 42, and the third wire guide machine 43. The first wire guide machine 41 is located in front of the first water washing tank 11, the second wire guide machine 42 is arranged between the first water washing tank 11 and the second water washing tank 12, and the third wire guide machine 43 is arranged at the outlet of the second water washing tank 12; the first wire guide machine 41, the second wire guide machine 42 and the third wire guide machine 43 are all driven by separate driving parts, which is conducive to adjusting the running speed of the wire bundle 100 and making the wire bundle 100 in a slightly relaxed state.

[0047] In this embodiment, the wet heat drawing machine 104 is located below the support platform 3 and is used as the oiling device 5. Figure 8 As shown, the bottom of the wet hot drawing machine 104 is provided with an oil inlet pipe 51 and an oil return pipe 52. A wire pressing guide rod 50 is provided inside the wet hot drawing machine 104, and the filaments 100 pass through the lower surface of the wire pressing guide rod 50. A liquid squeezing guide rod 53 is also provided at the end of the wet hot drawing machine 104 to squeeze out excess oil from the filaments 100. After the oiling treatment, the filaments 100 enter the drying equipment for drying. The drying equipment includes a first dryer 61, a second dryer 62, and a third dryer 63 arranged in sequence. Specifically, in this embodiment, the first dryer 61 is the dryer 105 in the spinning equipment, the second dryer 62 is the preheater 106 in the spinning equipment, and the third dryer 63 is the stretching machine 107 in the spinning equipment.

[0048] During use, the semi-finished spool car is pushed to the front of the spinning machine. In this embodiment, in order to deliver the filament bundle 100 to the water washing device, a channel guide rod and a tension frame 71 are also provided. The channel guide rod and tension frame 71 are arranged at the front end of the support platform 3 to guide and limit the filament bundle. The filament bundle 100 is delivered to the tension frame 71 through the channel guide rod. The tension frame 71 flattens the filament bundle 100 and applies a certain tension. After passing through the tension frame 71, the filament bundle 100 enters the first guide 41 and is continuously unwound from the spool car under the traction of the first guide 41. It then enters the first water washing tank 11, the second guide 42, the second water washing tank 12, and the third guide 43 in sequence. In particular, because the first guide 41, the second guide 42, and the third guide 43 in this embodiment are independently driven, the filament bundle 100 can be washed in a slightly relaxed state, which is conducive to the dispersion of the filament bundle 100. On the one hand, it can improve the dispersion of the fiber, and on the other hand, it can facilitate the diffusion of the salt paste from the fiber.

[0049] After being washed twice, the tow 100 enters the bunching machine 103 under the traction of the third wire guide machine 43 and is gathered into a bundle. Then, it enters the oiling device 5 under the traction of the bunching machine 103. A liquid pressing guide rod 53 is provided at the outlet of the oiling device 5. After being squeezed by the liquid pressing guide rod 53, the tow 100 enters the first dryer 61, the second dryer 62, and the third dryer 63 in sequence. The tow 100 after drying is cooled on the cooler 110 and finally packed and packaged by the swing wire machine. After the above treatment, the moisture content of the finished tow 100 is reduced to about 0.5%, the sodium sulfate in the tow 100 is reduced to below 0.1%, and the occurrence of twisting and sticking in the finished fiber tow 100 is reduced, and the fiber dispersion is effectively improved.

[0050] The above is only an embodiment of the present invention. The present invention is not limited to the field involved in this implementation case. Common knowledge such as the specific structure and characteristics of the scheme is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
