Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fiber cooling components, in particular to a hollow fiber preparation equipment stable to wind. BACKGROUND

[0002] Hollow fiber is a kind of chemical fiber with continuous cavity inside. It is like an extremely fine straw, with one or more holes throughout from the head to the tail of the fiber, and is often cooled and shaped using ring blowing equipment in production.

[0003] Publication No. CN216998681U discloses a ring blowing device for composite fiber yarn, comprising a shell, characterized in that: the lower surface of the shell is fixedly installed with a support seat through a support, an air inlet is formed through the surface of the shell, a ventilation pipe is fixedly installed at the air inlet position of the surface of the shell, a first annular plate is fixedly installed in the shell, an inner cylinder is fixedly installed on the upper surface of the first annular plate, a ventilation mesh cylinder is fixedly installed on the upper end of the inner cylinder, a second annular plate is fixedly installed in the shell, the upper end of the ventilation mesh cylinder is fixedly connected with the second annular plate, and a filter ring is arranged in the ventilation mesh cylinder. The device enables the cooling air flow to pass through the ventilation mesh cylinder and the filter ring and performs ring blowing cooling on the fiber yarn in the filter ring, thereby improving the cooling effect.

[0004] In actual production of hollow fibers, ring blowing cylinder equipment is usually used to fully cool and shape the hollow fibers. However, during the cooling process, the air fan blows air into the ring-shaped air duct through a single air inlet, and completes the temperature reduction and shaping of the hollow fibers through various air outlets in the ring-shaped air duct. Since the air fan blows air directly into the ring-shaped air duct, the air is likely to form a low pressure area on the opposite side of the air inlet after entering the ring-shaped air duct, resulting in uneven air pressure in the circumferential direction. At this time, the air discharge amount of the ring-shaped air duct at different directions changes due to the influence of the uneven air pressure in the circumferential direction, that is, the air blowing force at different blowing ports of the ring-shaped air duct is different, resulting in uneven cooling of the surface of the hollow fiber. Uneven cooling leads to different crystallization and solidification speeds of different parts of the hollow fiber. The part that cools faster solidifies first, and the viscosity increases, which hinders the collapse of the hollow part inside the hollow fiber under the action of surface tension. The part that cools slowly has a hollow part inside that collapses, resulting in uneven hollow degree and irregular cross-sectional shape of the hollow fiber. The existing equipment has further room for improvement in the uniformity of the hollow degree during the production of hollow fibers. SUMMARY

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0035] Embodiments

[0036] Please refer to Figures 1 to 5 A hollow fiber preparation device stable to wind, including ring blowing cylinder 1, the front end of ring blowing cylinder 1 is fixedly connected with control center 10, the top of ring blowing cylinder 1 is circumscribed with spinneret 12, one end surface of ring blowing cylinder 1 is fixedly connected with air inlet assembly 2, one end of air inlet assembly 2 penetrates to the inside of ring blowing cylinder 1, the rear end of the penetration part of air inlet assembly 2 is fixedly connected with air inlet cylinder 20, the front end of the penetration part of air inlet assembly 2 is fixedly connected with spiral air duct 13, the outer surface of spiral air duct 13 is fixedly connected at the inner wall of ring blowing cylinder 1, a plurality of electromagnets 131 are fixedly connected at the top and bottom surfaces of spiral air duct 13, electromagnets 131 are electrically connected with control center 10, a plurality of filter holes 130 are formed at the end of spiral air duct 13 away from the inner wall of ring blowing cylinder 1;

[0037] In the production of hollow fibers, it is usually necessary to use a ring blowing cylinder 1 device to fully cool and shape the hollow fibers, but during the cooling process, the air blowing of the fan 30 makes the air enter the ring-shaped air cylinder from a single air inlet and complete the cooling and shaping of the hollow fibers through each air outlet in the ring-shaped air cylinder. Since the air blowing of the fan 30 is straight blowing into the ring-shaped air guide, the air is easy to form a low pressure area on the opposite side of the air inlet after entering the ring-shaped air cylinder, resulting in uneven air pressure in the circumferential direction. At this time, the ring-shaped air cylinder is affected by the uneven air pressure in the circumferential direction when the air is discharged through the air outlet, causing the air discharge amount at different directions of the ring-shaped air cylinder to change, that is, the air blowing force at different blowing outlets of the ring-shaped air cylinder is different, resulting in uneven cooling of the surface of the hollow fiber. Uneven cooling will cause different crystallization and solidification speeds of different parts of the hollow fiber, and the parts that cool faster will solidify first, and the viscosity will increase, which will hinder the collapse of the hollow part inside the hollow fiber under the action of surface tension. The parts that cool slowly will appear collapse in the hollow part inside, resulting in uneven hollow degree and irregular cross-sectional shape of the hollow fiber;

[0038] The application discloses a kind of hollow fiber preparation equipment that wind is stable, and hollow fiber raw material after hot melting is shaped into multiple by spinneret 12 and falls to ring blowing cylinder 1 inside, air inlet cylinder 20 is connected with air blowing equipment, air blowing equipment blows air into air inlet assembly 2 by air inlet cylinder 20, and air is blown to spiral duct by air inlet assembly 2, since air enters spiral duct, it will rotate along spiral duct, and be acted on by centrifugal force, air will rotate ceaselessly in the whole internal path of spiral duct, and different pressure and speed air is forced to produce intense relative motion and mixing in the radial direction (i.e. thickness direction) of pipe in the rotation process, originally high-speed air in center is thrown to outer layer in spiral duct, and exchanges momentum with lower speed air along the way, and air in inner layer in spiral duct is also rolled to outer layer in spiral duct, this continuous radial mixing flattens the pressure and speed difference of each filter hole 130 in spiral duct, and since the length of internal path of spiral duct is much greater than the straight line distance of its height, to provide air with more sufficient time and space to exchange energy and momentum equalization, then air is sprayed to the outer surface of hollow fiber by filter hole 130 and is cooled and shaped to hollow fiber, to reduce the size of air blowing at different blowing outlets, make the cooling of the surface of hollow fiber uneven, cause the hollow degree of hollow fiber to be uneven, cross-sectional shape is irregular, improve the uniformity of hollow degree and the cooling effect of hollow fiber when the device is produced, convenient for user to use;

[0039] When the air is blown out at the filter holes 130 to the outer surface of the hollow fiber to cool and shape the hollow fiber in the above process, the filter holes 130 can filter part of the impurities (thread ends, raw material debris, etc.) in the air, so that only air is blown out at the filter holes 130, and the impurities remain in the spiral duct, reducing the case that part of the impurities are blown to the hollow fiber during the cooling process, causing the surface of the hollow fiber to mix with the impurities, thereby reducing the surface production quality of the hollow fiber, facilitating user use;

[0040] Please refer to Figures 1 to 5 Further in the above description, the inner wall of the ring air blower 1 is fixedly connected with a containing chamber 14, the bottom of the containing chamber 14 is fixedly connected at the other end of the spiral air duct 13 away from the air inlet assembly 2, the rear end surface of the containing chamber 14 is not closed, the inside of the containing chamber 14 is provided with a fixed block 140, the fixed block 140 is fixedly connected at one end close to the spiral air duct 13 with a cleaning head 141 matching the shape and size of the inner wall of the spiral air duct 13, and the top and bottom of the fixed block 140 are fixedly connected with a magnetic plate 142;

[0041] The plurality of electromagnets 131 are divided into multiple groups in several numbers, after the cooling is completed, the user can control the center 10 to sequentially open the electromagnets 131 in multiple groups from the bottom, the electromagnets 131 give the magnetic attraction force of the magnetic plate 142 inside the containing chamber 14, so that the fixed block 140 and the cleaning head 141 move along the inside of the electromagnet 131 and the spiral duct, the cleaning head 141 pushes the impurities remaining in the spiral duct in the above step during the movement, when the cleaning head 141 moves to the top of the spiral duct, the impurities will all be pushed to the inside of the air inlet assembly 2 for treatment, and the user only needs to give the magnetic repulsion force of the magnetic plate 142 by sequentially opening the electromagnets 131 of multiple groups from the top through the control center 10 to reset it, a limiting plate is fixed at the end where the spiral duct is connected with the air inlet assembly 2 to prevent the cleaning head 141 from moving to the inside of the air inlet assembly 2 when it is given the magnetic repulsion force of the magnetic plate 142 by the electromagnet 131, so that the device can automatically complete the cleaning step of the inside of the spiral duct after the cooling is completed, facilitating user use;

[0042] Please refer to Figures 3 to 8 Further in the above description, the through portion of the air assembly is fixedly connected with a first filter plate 21, one side surface of the first filter plate 21 is fixedly connected with an adsorption plate 22, and the adsorption plate 22 is made of a high-viscosity electrostatic adsorption material;

[0043] The first filter plate 21 is used to preliminarily filter the air when the air blowing assembly delivers the air through the air inlet cylinder 20;

[0044] Please refer to Figures 3 to 8Further in the foregoing description, the inner wall of one end of the air inlet assembly 2 is fixedly connected with two first linear drive assemblies 23, and the adsorption plate 22 is arranged at the center of the two first linear drive assemblies 23. The first linear drive assembly 23 is a electric push rod. The other side output end of the first linear drive assembly 23 is fixedly connected with a top plate 230. The end of the top plate 230 away from the first linear drive assembly 23 is fixedly connected with a second filter plate 231. The other side of the second filter plate 231 is fixedly connected with a second linear drive assembly 232. The end output end of the second linear drive assembly 232 close to the adsorption plate 22 is fixedly connected with a push plate 233. The push plate 233 is made of high elasticity rubber material;

[0045] When the user needs to clean the impurities on the first filter plate 21, the user can select to open the first linear drive assembly 23 at the rear end or the front end through different steps (cleaning the rear end of the first filter plate 21 in the air inlet step, cleaning the inner front end of the air inlet assembly 2 in the spiral pipe cleaning step). The first linear drive assembly 23 is opened to push the top plate 230 to move. The top plate 230 moves to drive the second linear drive assembly 232 to move. The second filter plate 231 is used to replace the first filter plate 21 to filter the air during the process of cleaning the rear end of the first filter plate 21 in the air inlet step. The device can continuously clean the air without stopping. When the second linear drive assembly 232 moves to the rightmost end as shown in Figure 4 , the second linear drive assembly 232 is opened to drive the push plate 233 to move towards the direction of the impurities until the push plate 233 contacts the first filter plate 21. At this time, the first linear drive assembly 23 is opened by the control center 10 to reset the top plate 230 and the second filter plate 231. The second filter plate 231 pushes the impurities to the adsorption plate 22 through the push plate 233 during the resetting process. The impurities are adsorbed by the material properties of the adsorption plate 22 itself. The user only needs to open the air inlet assembly 2 to replace the adsorption plate 22 to complete the entire cleaning step. The second blanking plate is reset by the control center 10 to reset the push plate 233. Thus, the device can collect and clean the impurities in the air inlet stage and the cleaning stage respectively, avoiding the influence of the impurities on the air delivery in the next use, and facilitating the user to use;
