Description

Technical Field

[0002] Chemical fiber melt spinning equipment usually includes a hopper, an extruder, a spinning box, a drawing device, and a winding device. The raw material is put into the extruder from the hopper. The extruder melts the raw material and extrude it into the spinning box. The raw material is then pulled out from the nozzle of the spinning box and enters the drawing device. After passing through the drawing device, it is wound onto the winding device. After being ejected from the nozzle, a blowing device is usually required to blow and cool the silk thread between the nozzle and the drawing device. After cooling, the silk thread enters the drawing device to ensure the stability of the filament.

[0003] Since the winding speed of the filament bundle is relatively fast during the spinning process, in order to ensure the cooling effect of the filament bundle, the length of the filament bundle in the air cooling area will be relatively long, so as to ensure that the filament bundle can be completely cooled and formed. In this case, the cold air used for cooling will disturb the airflow, and the vibration caused by the rapid and large-span movement of the filament bundle itself in the air can easily cause the filament bundle to shake and sway, resulting in mutual entanglement between the filament bundles, affecting the spinning output, or interfering with the filament bundle that has not yet been fully formed, causing serious deformation or breakage of the filament bundle, affecting the quality of spinning.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] like Figures 1 to 9 As shown, a chemical fiber melt spinning device according to the present invention comprises a cooling mechanism, which is installed below a spinning assembly 11. The cooling mechanism comprises a shell 1, which is installed below the spinning assembly 11. An air inlet pipe 12 is installed on the shell 1. A porous plate 13 is installed in the shell 1. From the outside to the inside, there are a blowing chamber 14 and a cooling chamber 16 in the shell 1. The filament bundle 4 spun from the spinning assembly 11 passes through the cooling chamber 16.

[0036] Multiple groups of guide wires 2 are installed in the housing 1 from top to bottom, and the projection of any group of guide wires 2 on the horizontal plane forms at least one grid, and the grid guides and separates the wire bundles 4 from each other;

[0037] Mounting blocks 3 are respectively installed at both ends of the guide wire 2, and the mounting blocks 3 are mounted on the housing 1 by snapping, and the length of the mounting blocks 3 is greater than the distance between the porous plate 13 and the inner wall of the housing 1, and a magnetic block 322 is installed on the mounting block 3, and the magnetic block 322 is fixed on the housing 1 by magnetic adsorption;

[0038] During operation, the filament bundle 4 from the spinning assembly 11 enters the cooling chamber 16 from the upper end. At this time, the external fan sends the purified cold air with a lower temperature into the blowing chamber 14 through the air inlet pipe 12, so that the cold air in the blowing chamber 14 is tidied by the porous plate 13 and then blown out to the cooling chamber 16 stably and evenly, so as to cool the filament bundle 4. After cooling, the filament bundle 4 is discharged from the opening at the bottom of the shell 1 and enters the subsequent process. At the same time, the cold air in the cooling chamber 16 that has completed the work is discharged from the opening at the bottom of the shell 1.

[0039] Since the projection of any group of guide wires 2 on the horizontal plane will form at least one grid, the grid is used to separate the filament bundles 4 in the cooling chamber 16 as much as possible, so as to guide and restrict the filament bundles 4, and avoid large-scale shaking, jittering or deviation between the filament bundles 4 when the cold wind blows on the filament bundles 4 to cool them down, causing adjacent filament bundles 4 to be entangled with each other, or causing the filament bundles 4 to be deformed or broken, thereby affecting the derivation and quality of spinning;

[0040] At the same time, since there are multiple groups of guide wires 2 from top to bottom, when the filament bundle 4 passes through the cooling chamber 16, the filament bundle 4 can be stably and fully restricted and guided by the grid formed by the guide wires 2, and the filament bundle 4 can be prevented from floating in the air and spreading in all directions during the derivation process as much as possible, thereby reducing the possibility of deviation of the filament bundle 4;

[0041] At the same time, since the diameter of the guide wire 2 is relatively thin, and there is a relatively large gap between the guide wires 2 relative to their diameters, the interference of the guide wire 2 on the flow of the cold air in the cooling chamber 16 is relatively low, so as to maintain a stable and uniform cooling flow, reduce the possibility of turbulence caused by the cold air in the cooling chamber 16 being disturbed, and avoid affecting the quality of spinning;

[0042] At the same time, since any group of guide wires 2 includes multiple guide wires 2, a grid is formed between the guide wires 2 so that the grid can separate, guide and limit the multiple groups of tows 4 coming out of the spinning assembly 11, prevent the tows 4 from shaking and trembling significantly during the cooling process, and ensure smooth spinning and good spinning quality. At the same time, there are gaps in the vertical direction between the guide wires 2 in the same group, thereby avoiding mutual contact between the guide wires 2, so that an angle formed by the contact between two guide wires 2 appears in the grid formed by the guide wires 2, which affects the guidance and restriction of the tows 4. At the same time, the gaps in the vertical direction between the guide wires 2 can also facilitate the installation of the guide wires 2 on the shell 1;

[0043] At the same time, in order to facilitate the disassembly, installation, inspection and maintenance of the cooling mechanism, the shell 1 in the cooling mechanism is composed of two or four symmetrical parts that are assembled together, and the two or four parts that make up the shell 1 can be individually disassembled from the spinning component 11, thereby facilitating the inspection of the cooling mechanism and the disassembly and installation of the guide wire 2.

[0044] As an embodiment of the present invention, the mounting block 3 includes a control block 31 and a fixed block 32, and a magnetic block 322 is installed on the fixed block 32. The control block 31 and the fixed block 32 are both clamped and installed on the housing 1. The end of the fixed block 32 away from the guide wire 2 does not pass out of the housing 1, and the end of the control block 31 away from the guide wire 2 passes out of the housing 1;

[0045] A soft spring 33 is installed on the mounting block 3, and both ends of the guide wire 2 are connected to the soft spring 33;

[0046] By installing the magnetic block 322 on the fixing block 32, the fixing block 32 is snap-fitted into the mounting hole on the housing 1, and the fixing block 32 is fixed to the housing 1 by the magnetic force, so as to prevent the fixing block 32 from being separated from the housing 1, thereby affecting the installation and subsequent normal operation of the guide wire 2. Similarly, the control block 31 will also be snap-fitted and fixed to the housing 1, so as to prevent the control block 31 from being separated from the housing 1 at will, thereby affecting the normal operation of the guide wire 2. At the same time, when the guide wire 2 needs to be disassembled, replaced or maintained, the staff can also relatively easily remove the fixing block 32 and the control block 31 from the housing 1 using tools.

[0047] At the same time, since a soft spring 33 is installed on the mounting block 3, the guide wire 2 installed on the soft spring 33 is allowed to move slightly during normal operation, thereby having a buffering effect when guiding and restricting the filament bundle 4. The buffering effect is utilized to better guide and restrict the filament bundle 4, thereby preventing the guide wire 2 from having no buffering range, causing the filament bundle 4 that contacts the guide wire 2 to be subjected to excessive force when the shaking amplitude is large, resulting in serious deformation of the filament bundle 4 or breakage of the filament bundle 4, thereby affecting the normal spinning process.

[0048] As an embodiment of the present invention, the guide wire 2 is made of metal material, the guide wire 2 and the housing 1 are electrically connected to each other, and the housing 1 is grounded;

[0049] During the spinning process, the filament bundle 4 is prone to carry static electricity, which causes the filament bundles 4 to attract and entangle with each other due to static electricity. At the same time, the guide wire 2 is made of metal material, so that the static electricity carried by the filament bundle 4 can be transferred to the guide wire 2 during the process of being guided and restricted after the filament bundle 4 contacts the guide wire 2, and then released from the grounding point of the shell 1, thereby reducing or avoiding the static electricity carried by the filament bundle 4, so as to prevent the filament bundle 4 from being entangled due to the influence of static electricity, thereby affecting the spinning process.

[0050] As an embodiment of the present invention, the guide wire 2 includes an inner layer and an outer layer, the outer layer is a metal wire 21, the inner layer is a cotton yarn 22 and a thin straight rod 23, and the structure of the guide wire 2 is a core-spun yarn structure;

[0051] A sponge block 34 is installed on the soft spring 33, and the sponge block 34 is located at the connection between the soft spring 33 and the guide wire 2, and the sponge block 34 is impregnated with a spinning oil;

[0052] Since the sponge block 34 is installed on the soft spring 33, and the structure of the guide wire 2 is a core-spun yarn structure, the spinning oil impregnated in the sponge block 34 will gradually penetrate into the cotton yarn 22, and slowly move from the cotton yarn 22 to the surface of the guide wire 2 under the action of penetration and capillary action, and infiltrate the surface of the guide wire 2, so that when the guide wire 2 guides and restricts the yarn bundle 4, the friction between the yarn bundle 4 and the guide wire 2 is reduced and adhesion between the yarn bundle 4 and the guide wire 2 is avoided, resulting in deformation or breakage of the yarn bundle 4, affecting the normal spinning process;

[0053] At the same time, the metal wire 21 is used as the outer layer in the guide wire 2 to reduce the friction between the guide wire 2 and the wire bundle 4, and reduce the wear of the outer layer on the guide wire 2 to prevent the guide wire 2 from being worn and broken. At the same time, the cotton yarn 22 in the inner layer is used to conduct the spinning oil so that the spinning oil can be gradually transferred from the sponge block 34 to the surface of the entire guide wire 2 to lubricate the surface of the guide wire 2. At the same time, the thin straight rod 23 in the inner layer is used to ensure the linearity of the guide wire 2 to avoid bending and deformation of the guide wire 2.

[0054] As another embodiment, the guide wire 2 can also directly use a thin metal rod with axially distributed narrow grooves on the surface, and use the narrow grooves on the surface of the thin metal rod to store the spinning oil, and diffuse and move the spinning oil in the narrow grooves through capillary action.

[0055] As an embodiment of the present invention, a rotating ring 331 is installed on the soft spring 33, and the guide wire 2 is rotatably installed on the rotating ring 331;

[0056] Since the guide wire 2 is rotatably mounted on the rotating ring 331, when the guide wire 2 guides and restricts the wire bundle 4, there will be relative friction between the wire bundle 4 and the guide wire 2. At this time, the guide wire 2 will rotate around the rotating ring 331 under the action of the friction force, so that the friction between the guide wire 2 and the wire bundle 4 is changed from sliding friction to rolling friction, so that the friction between the guide wire 2 and the wire bundle 4 is relatively reduced, thereby avoiding the adverse effect of the friction on the wire bundle 4;

[0057] At the same time, since the spinning oil on the surface of the guide wire 2 is infiltrated from the cotton yarn 22 in the inner layer, when the tow 4 moves at a high speed during the spinning process, it is easy for the tow 4 to rub off the spinning oil on the surface of the guide wire 2, and the spinning oil in the cotton yarn 22 will not have time to infiltrate the surface of the guide wire 2. Therefore, by rotating the guide wire 2, different parts of the circumference of the guide wire 2 are contacted with the tow 4, ensuring that the spinning oil exists at the part of the surface of the guide wire 2 that contacts the tow 4.

[0058] At the same time, the rotation of the guide wire 2 will also generate centrifugal force, which promotes the spinning oil in the cotton fiber to penetrate into the surface of the guide wire 2, further ensures the presence of spinning oil on the surface of the guide wire 2, and reduces the friction between the guide wire 2 and the fiber bundle 4. At the same time, when the guide wire 2 rotates, the end of the guide wire 2 located in the sponge block 34 will also scratch the sponge block 34, thereby promoting the spinning oil infiltrated in the sponge block 34 to be transferred to the guide wire 2 and spread in the cotton fibers in the guide wire 2.

[0059] As an embodiment of the present invention, blades 35 are installed at both ends of the guide wire 2, the blades 35 are close to but not in contact with the sponge block 34, and the blades 35 are clamped and installed on the guide wire 2;

[0060] Since the wire bundle 4 is relatively small and fragile, and the contact area between the wire bundle 4 and the guide wire 2 is relatively small, when the guide wire 2 guides and restricts the wire bundle 4, it is not easy for the wire bundle 4 to drive the guide wire 2 to rotate. Therefore, blades 35 are installed at both ends of the guide wire 2, so that the cold wind flowing from top to bottom in the cooling chamber 16 blows the blades 35, thereby rotating the guide wire 2 and reducing the friction between the guide wire 2 and the wire bundle 4;

[0061] At the same time, since the blades 35 are located at both ends of the guide wire 2, that is, the blades 35 are close to the inner wall of the shell 1, the distance between the blades 35 and the filament bundle 4 located in the middle position of the shell 1 is relatively large. When the cold wind blows on the blades 35 and causes the cold wind flow near the inner wall of the shell 1 to fluctuate, the cold wind in the middle position of the shell 1 can still maintain a stable and uniform flow, avoiding turbulence or large turbulence of the cold wind, which affects the cooling of the filament bundle 4.

[0062] As an embodiment of the present invention, a partition 15 is installed between the inner wall of the shell 1 and the porous plate 13, and a plurality of the partitions 15 are arranged from top to bottom. The partitions 15 divide the blowing chamber 14 between the inner wall of the shell 1 and the porous plate 13 into a plurality of relatively independent blowing spaces;

[0063] The housing 1 is provided with a plurality of air inlet pipes 12, the air inlet pipes 12 being connected to the upper end of the blowing space, and the blowing space and the air inlet pipes 12 are in one-to-one correspondence;

[0064] The blowing chamber 14 is divided into a plurality of independent blowing spaces, and cold air is introduced into the blowing spaces through independent air inlet pipes 12, so that the temperature of the cold air in the blowing chamber 14 is constant after passing through the porous plate 13 and entering the cooling chamber 16, thereby ensuring a uniform temperature of the cold air in the cooling chamber 16 and a stable and uniform flow of the cold air, thereby ensuring the cooling effect of the filament bundle 4 and avoiding temperature differences between the upper and lower parts of the cooling chamber 16, which would cause uneven cooling of the filament bundle 4 and affect the quality of spinning.

[0065] As an embodiment of the present invention, the control block 31 is provided with a through insertion hole 311, the fixing block 32 is provided with a fixing hole 321, a connecting rod 36 is installed between the control block 31 and the fixing block 32, one end of the connecting rod 36 is inserted into the fixing hole 321, and the other end of the connecting rod 36 is located in the insertion hole 311;

[0066] The connecting rod 36 and the guide wire 2 are symmetrically distributed around the center line of the mounting block 3, and the connecting rod 36 is a flat rod;

[0067] When disassembling and installing the guide wire 2, the staff inserts the connecting rod 36 into the installation guide control block 31 and the fixing block 32, so that the control block 31, the fixing block 32 and the guide wire 2 are forcibly connected, thereby improving their overall rigidity, facilitating the disassembly and installation of the staff, and avoiding bending and shaking between the control block 31 and the fixing block 32 in the absence of the connecting rod 36, which affects the staff's operation and increases the difficulty and workload of the staff;

[0068] At the same time, since the connecting rod 36 and the guide wire 2 are symmetrically distributed around the center line of the mounting block 3, and the connecting rod 36 is a flat rod, when the staff installs the guide wire 2, the staff determines the position of the guide wire 2 in the shell 1 by the state of the connecting rod 36, thereby facilitating the positioning of the guide wire 2 in the shell 1 and avoiding the guide wire 2 from being skewed or offset, which affects the formation of a grid between the guide wires 2.

[0069] The specific workflow is as follows:

[0070] During operation, the filament bundle 4 from the spinning assembly 11 enters the cooling chamber 16 from the upper end, and the filament bundle 4 after cooling is discharged from the opening at the bottom of the shell 1 and enters the subsequent process. At the same time, the cold air in the cooling chamber 16 that has completed the work is discharged from the opening at the bottom of the shell 1;

[0071] Since the projection of any group of guide wires 2 on the horizontal plane will enclose at least one grid, the grid is used to separate the wire bundles 4 in the cooling cavity 16 as much as possible, and the wire bundles 4 are guided and restricted;

[0072] At the same time, since there are multiple groups of guide wires 2 from top to bottom, when the wire bundle 4 passes through the cooling chamber 16, the wire bundle 4 can be stably and fully restricted and guided by the grid formed by the guide wires 2;

[0073] At the same time, since the diameter of the guide wire 2 is relatively thin, and there is a relatively large gap between the guide wires 2 relative to their diameters, the interference of the guide wire 2 on the flow of the cold air in the cooling cavity 16 is relatively low;

[0074] At the same time, since any group of guide wires 2 includes multiple guide wires 2, a grid is formed between the guide wires 2 so that the grid can separate, guide and limit the multiple groups of tows 4 coming out of the spinning assembly 11, and at the same time, there are gaps in the vertical direction between the guide wires 2 in the same group;

[0075] At the same time, in order to facilitate the disassembly, installation, inspection and maintenance of the cooling mechanism, the housing 1 in the cooling mechanism is composed of two or four symmetrical parts, and the two or four parts constituting the housing 1 can be individually disassembled from the spinning assembly 11;

[0076] By installing the magnetic block 322 on the fixing block 32, the fixing block 32 is fixed on the housing 1 by magnetic force. Similarly, the control block 31 is also clamped and fixed on the housing 1. At the same time, when the guide wire 2 needs to be disassembled, replaced or maintained, the staff can also relatively easily remove the fixing block 32 and the control block 31 from the housing 1 using tools;

[0077] At the same time, since the mounting block 3 is provided with a soft spring 33, the guide wire 2 mounted on the soft spring 33 is allowed to move slightly during normal operation, thereby providing a buffering effect when guiding and limiting the wire bundle 4, and the wire bundle 4 is better guided and limited by utilizing the buffering effect;

[0078] The guide wire 2 is made of metal material, so that when the wire bundle 4 contacts the guide wire 2 and is guided and restricted, the static electricity carried by the wire bundle 4 can be transferred to the guide wire 2 and then released from the grounding point of the housing 1;

[0079] Since the sponge block 34 is installed on the soft spring 33, and the structure of the guide wire 2 is a core-spun yarn structure, the spinning oil impregnated in the sponge block 34 will gradually penetrate into the cotton yarn 22, and slowly move from the cotton yarn 22 to the surface of the guide wire 2 under the action of penetration and capillary action, and infiltrate the surface of the guide wire 2, so that when the guide wire 2 guides and restricts the yarn bundle 4, the friction between the yarn bundle 4 and the guide wire 2 is reduced and adhesion between the yarn bundle 4 and the guide wire 2 is avoided;

[0080] At the same time, the metal wire 21 is used as the outer layer in the guide wire 2 to reduce the friction between the guide wire 2 and the tow 4, and reduce the wear of the outer layer on the guide wire 2. At the same time, the cotton yarn 22 in the inner layer is used to conduct the spinning oil so that the spinning oil can be gradually transferred from the sponge block 34 to the surface of the entire guide wire 2. At the same time, the thin straight rod 23 in the inner layer is used to ensure the linearity of the guide wire 2;

[0081] As another embodiment, the guide wire 2 may also directly use a thin metal rod with axially distributed narrow grooves on the surface, and the narrow grooves on the surface of the thin metal rod are used to store the spinning oil, and the spinning oil is diffused and moved in the narrow grooves through capillary action;

[0082] Since the guide wire 2 is rotatably mounted on the rotating ring 331, when the guide wire 2 guides and restricts the wire bundle 4, there will be relative friction between the wire bundle 4 and the guide wire 2. At this time, the guide wire 2 will rotate around the rotating ring 331 under the action of the friction force, so that the friction between the guide wire 2 and the wire bundle 4 is converted from sliding friction to rolling friction, so that the friction between the guide wire 2 and the wire bundle 4 is relatively reduced;

[0083] By rotating the guide wire 2, different parts of the circumference of the guide wire 2 are brought into contact with the filament bundle 4, ensuring that the spinning oil is present at the part where the surface of the guide wire 2 contacts the filament bundle 4;

[0084] At the same time, the rotation of the guide wire 2 will also generate centrifugal force, which promotes the spinning oil in the cotton fiber to penetrate into the surface of the guide wire 2. At the same time, when the guide wire 2 rotates, the end of the guide wire 2 located in the sponge block 34 will also scrape the sponge block 34, thereby promoting the transfer of the spinning oil infiltrated in the sponge block 34 to the guide wire 2.

[0085] Blades 35 are installed at both ends of the guide wire 2, so that the cold wind flowing from top to bottom in the cooling chamber 16 blows the blades 35, thereby causing the guide wire 2 to rotate;

[0086] At the same time, since the blades 35 are located at both ends of the guide wire 2, that is, the blades 35 are close to the inner wall of the shell 1, the distance between the blades 35 and the wire bundle 4 located in the middle of the shell 1 is relatively large. When the cold wind blows on the blades 35, causing the cold wind flow near the inner wall of the shell 1 to fluctuate, the cold wind in the middle of the shell 1 can still maintain a stable and uniform flow.

[0087] The blowing chamber 14 is divided into a plurality of independent blowing spaces, and cold air is introduced into the blowing spaces through independent air inlet pipes 12, so that the cold air in the blowing chamber 14 passes through the porous plate 13 and enters the cooling chamber 16 with a constant temperature, thereby ensuring that the cold air temperature in the cooling chamber 16 is uniform and the flow of the cold air is stable and uniform;

[0088] When disassembling and installing the guide wire 2, the staff inserts the connecting rod 36 into the installation guide control block 31 and the fixing block 32, so that the control block 31, the fixing block 32 and the guide wire 2 are forcibly connected, thereby improving their overall rigidity, facilitating the disassembly and installation of the staff, and avoiding bending and shaking between the control block 31 and the fixing block 32 in the absence of the connecting rod 36, which affects the staff's operation and increases the difficulty and workload of the staff;

[0089] At the same time, since the connecting rod 36 and the guide wire 2 are symmetrically distributed around the center line of the mounting block 3, and the connecting rod 36 is a flat rod, when the staff installs the guide wire 2, the staff determines the position of the guide wire 2 in the shell 1 by the state of the connecting rod 36, thereby facilitating the positioning of the guide wire 2 in the shell 1 and avoiding the guide wire 2 from being skewed or offset, which affects the formation of a grid between the guide wires 2.
