Description

Technical Field

[0001] The invention belongs to the technical field of hollow mother yarn processing, and in particular relates to a processing method of a semi-bright hollow mother yarn. Background Art

[0002] During the processing of existing hollow mother yarns, raw materials such as polymer slices are heated to melt, then accurately metered by a metering pump, and then extruded through a specially designed hollow spinneret to form a bundle of fibers with a hollow structure, which is finally cooled and solidified. The shape and structural dimensions of the spinneret are crucial, including the slit length of the spinneret hole, the distance between the two slit tips, the equivalent diameter, etc. The use of an arc slit spinneret can spin fibers with a thinner outer diameter and appropriate hollowness. At the same time, parameters such as the wind speed, temperature and humidity of the ring blowing need to be precisely controlled to ensure the cooling uniformity and curing effect of the hollow mother yarn. However, in the actual processing process, the existing hollow mother yarn cannot guarantee the continuity of its oiling by using the ring blowing method, and the blowing method also limits the integration of hollow mother yarn production.

[0003] In order to solve the deficiencies of the prior art, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a hollow fiber processing device [202411099250.5], which includes a base with a T-shaped slide in the middle, a slide seat sliding in the T-shaped slide, and a cross frame sliding on the slide seat, the sliding direction of the cross frame on the slide seat is perpendicular to the T-shaped slide, two support plates are symmetrically connected to the cross frame, and a horizontal shaft for installing a winding frame is rotated on the two support plates, a bottom plate is fixed at one end of the T-shaped slide, two swing frames are rotated on the bottom plate, two arm plates are arranged near the bottom plate side of the cross frame, and the two swing frames are respectively connected to the two arm plates, and the base is symmetrically fixed with two vertical plates away from the bottom plate end, and the two vertical plates are rotated with support shafts, a frame is fixed between the two support shafts, and two tensioning wheels are rotated in the frame, and a torsion spring is arranged between the vertical plate and the support shaft.

DETAILED DESCRIPTION

[0033] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figure 1-10 As shown, a method for processing a semi-bright hollow mother yarn comprises the following steps:

[0035] S1: The masterbatch is melted and input into the spinneret 1. The masterbatch raw material used to produce the semi-gloss hollow master yarn is heated to a molten state, and then the molten masterbatch is transported to the spinneret 1. The spinneret 1 is a key component for the subsequent formation of the hollow master yarn. It has a built-in structure such as a channel, and the molten masterbatch enters it to prepare for the next step of extruding the hollow master yarn;

[0036] S2: The spinneret 1 is extruded through the hollow forming component 2 to form a hollow mother filament. The hollow forming component 2 is independent of the spinneret 1 and can be adjusted and replaced according to actual needs;

[0037] S3: Cooling is performed through the side blowing component 3 to ensure the molding quality of the hollow mother yarn and the separation degree of adjacent hollow mother yarns to avoid entanglement;

[0038] S4: The hollow mother yarn is oiled by the oil spraying assembly 5 and the excess oil is recovered by the oil filtering assembly 6. The oil spraying assembly 5 adopts a spraying type, and the excess oil needs to be recovered and processed by the oil filtering assembly 6;

[0039] S5: The winding assembly 4 corresponds to the hollow molding assembly 2 one by one, and the winding assembly 4 guides the hollow mother yarn to be wound and stored.

[0040] Specifically, the hollow forming assembly 2 is arranged inside the spinneret 1, the side blowing assembly 3 and the winding assembly 4 are installed below the spinneret 1, the oil spraying assembly 5 and the oil filtering assembly 6 are arranged between the side blowing assembly 3 and the winding assembly 4, and the winding assembly 4 is equipped with a sensor assembly. The sensor assembly cooperates with the winding assembly 4 to maintain the tension and transmission rate of the hollow mother yarn in a negative feedback regulation manner.

[0041] In depth, the spinneret 1 includes a main plate body 11 in the shape of a long strip and a sub-plate body 12 covering the upper end of the main plate body 11, a spinneret core 7 is pressed and fixed between the main plate body 11 and the sub-plate body 12, and the hollow molding component 2 is installed at the lower end of the main plate body 11 and connected to the spinneret core 7.

[0042] In addition, unlike the conventional straight-row spinneret structure, the spinneret inner core 7 in this embodiment includes a core plate 71, and the core plate 71 has a plurality of extrusion chambers 72 built therein. The extrusion chambers 72 are connected in parallel with the confluence chamber 74 through the liquid inlet pipe 73, and the liquid inlet pipe 73 is connected with a plurality of buffer tubes 75 with closed ends. The lengths of the buffer tubes 75 arranged from the confluence chamber 74 toward the extrusion chamber 72 are shortened one by one. The buffer tubes 75 are filled with inert gas and a buffer valve block 76 is slidably installed at the end opposite to the liquid inlet pipe 73. When the melt is input into the core plate 71, the plurality of buffer tubes 75 maintain the melt flow stability to avoid impact. A cavity is also left between the core plate 71 and the spinneret 1 to facilitate the assembly of the heating component and maintain the melt in a molten state. The extrusion chamber 72 is connected in parallel with the drainage chamber 78 through the liquid outlet pipe 77, and the drainage chamber 78 has an elastic buffer built therein, and the elastic buffer is connected with a buffer valve plate 79 slidably connected to the drainage chamber 78. The excess melt is discharged from the liquid outlet pipe 77 , thereby ensuring the melt fluidity inside the spinneret core 7 .

[0043] At the same time, the hollow molding component 2 adopts a replaceable structure, specifically including a molding plate 21 that is slidably plugged into the lower end of the main body 11, and the molding plate 21 is provided with molding units 22 that correspond one to one with the extrusion chamber 72, and each molding unit 22 can extrude a single strand or multiple strands of hollow mother filaments; the molding unit 22 includes a molding hole 23 provided on the molding plate 21, and a molding block 23 is inserted into the molding hole 23, and a molding step surface 24 that fits each other is provided between the molding hole 23 and the molding block 23, and an extrusion hole 25 in the shape of a V or C is opened on the molding block 23. The number of molding blocks 23 on the molding plate 21 is adjusted according to actual needs, and the molding block 23 can select extrusion holes 25 of other shapes according to actual needs, so as to meet different fiber molding requirements.

[0044] It can be seen that compared with the existing ring blowing structure, the side blowing assembly 3 in this embodiment is convenient for the integrated processing of hollow mother yarns, which specifically includes a number of blowing chambers 31 arranged one by one up and down, the blowing chamber 31 is in the shape of a long strip and has a blowing cavity 32 inside, and a blowing port 33 connected to the blowing cavity 32 is opened on the side of the blowing chamber 31, and the blowing port 33 is distributed in a matrix, and a windshield 34 is inserted into the inside of the blowing chamber 31, and a vent 35 opposite to the blowing port 33 is opened on the windshield 34, and a number of guide baffles 36 are installed in the blowing cavity 32, and a guide channel 37 opposite to the blowing port 33 is left between adjacent guide baffles 36. The opening and closing angles of each windshield 34 and the blowing volume can be adjusted according to actual needs, and the internal guide channel 37 ensures that the air volume between adjacent windshields 34 is maintained consistent. When the hollow mother yarn is transmitted downward, the blowing port 33 and the hollow mother yarn remain relatively closed, which is convenient for subsequent oiling.

[0045] Obviously, in order to reduce the amount of oil used and improve the uniformity of oiling, the oil injection assembly 5 in this embodiment adopts spraying treatment, including an oil injection pipe 51 installed at the front end of the blowing port 33, a plurality of spray heads 52 are connected in series on the oil injection pipe 51, a compression chamber 53 is arranged inside the spray head 52, a closing rod 54 is slidably installed in the compression chamber 53, a closing plate 55 is arranged at the end of the closing rod 54 away from the oil injection pipe 51, and an elastic reset member is arranged between the closing rod 54 and the compression chamber 53; a compression cylinder 56 is fixed on the closing rod 54, the end of the compression cylinder 56 away from the oil injection pipe 51 is closed and the end close to the oil injection pipe 51 is connected to the compression chamber 53, and the compression cylinder 56 has jet holes 57 evenly arranged along the circumference. When the oil is input into the oil injection pipe 51, the compression cylinder 56 pops up and sprays, otherwise the spray head 52 is in a closed state to prevent the falling fibers from clogging the jet holes 57. Since the spray head 52 is located at the blowing port 33, the hollow mother wire can be oiled during the process of blowing and cooling.

[0046] Preferably, similar to the conventional winding structure, the winding assembly 4 in this embodiment includes a winding base 41, which is connected to a winding reel 43 through a winding motor 42 and a variable speed gear set. A pair of vertically arranged suspension columns 44 are installed on the upper end of the winding base 41, and suspension rods 45 are slidably installed on the suspension columns 44, and suspension seats 46 are slidably installed on the suspension rods 45. A limiting roller 47 is rotatably installed on the suspension seats 46, and a lifting screw is slidably installed between the suspension columns 44 and the suspension rods 45, and a gear rack is installed between the suspension rods 45 and the suspension seats 46. The limiting roller 47 can be lifted up and down and can also slide left and right, so as to adjust its relative distance to realize the dynamic adjustment of the transmission path of the hollow mother wire. The limiting roller 47 and the limiting roller 47 are usually provided with a guide groove surrounding the circumference.

[0047] Obviously, the oil filter assembly 6 is usually assembled with the winding assembly 4, including an oil return drum 61 rotatably mounted on the winding base 41, and the oil return drum 61 is usually located between the limit drums 47. An arc-shaped oil return block 62 is fixed below the oil return drum 61, and an oil return groove 63 is opened on the oil return block 62, which is slidably connected to the edge of the oil return drum 61. When the hollow mother wire after oiling contacts the oil return drum 61, the excess oil flows into the oil return groove 63 of the oil return block 62. The oil return groove 63 is connected to the centrifugal filter assembly 8 through the oil return pipe 64; the centrifugal filter assembly 8 includes a collecting cylinder 81, which is connected to the liquid storage tank 84 through a liquid pump 82 and a liquid infusion pipe 83. The center of the collecting cylinder 81 is rotatably mounted with a cylindrical filter screen 86 through a centrifugal motor 85, and a guide plate 87 that can slide up and down and separate is installed inside the filter screen 86. The guide plate 87 is spiral and has a scraper 88 that fits the inside of the filter screen 86. The filter screen 86 rotates at high speed to separate the oil from the fibers, and the inside of the filter screen 86 can be quickly cleaned by lifting the guide plate 87.

[0048] In addition, the sensor assembly in this embodiment includes a variety of sensor elements, including a tension sensor arranged on the winding drum 43, a pressure sensor installed between the limit roller 47 and the suspension seat 46, and a photo sensor installed on the winding base 41. The sensors cooperate with each other and cooperate with the main control unit built into the winding assembly 4 to control the start and stop and speed of the winding motor 42, the lifting screw, and the gear rack and other components.

[0049] To sum up, the principle of this embodiment is that the spinneret core 7 built into the spinneret 1 guides the melt circulation and distribution, the melt is extruded and formed by the hollow molding component 2 to obtain a hollow mother yarn, wherein the side blowing component 3 cools and the oil spraying component 5 oils, the winding component 4 winds and stores the hollow mother yarn and the oil filter component 6 removes and recovers excess oil.
