Technical Field

[0001] This invention relates to the field of spinneret technology, specifically to a composite spinneret based on differentiated short fibers and its usage method. Background Technology

[0002] The composite spinneret for differentiated short fibers is an advanced textile industry equipment. It integrates multiple polymer melts or solutions into an independent spinneret system to produce short fibers with different materials, cross-sectional shapes, dyeing properties, or shrinkage rates in a single production process. This produces composite fiber materials with special structures and properties, which are widely used in clothing, home textiles, medical and health care, and other fields to meet the diverse market demand for functional and differentiated fibers.

[0003] Differentiated staple fibers are a class of fibers manufactured through innovative processes. They possess unique physical, chemical, or mechanical properties to meet specific application requirements. These fibers may differ from traditional staple fibers in material composition, cross-sectional shape, surface properties, or structure, thereby endowing them with better strength, softness, water absorption, antibacterial properties, flame retardancy, or other special functions.

[0016] The method of using a composite spinneret based on differentiated short fibers

[0017] S1: When mixing raw materials with different flowability and heat resistance inside the mixing cylinder, the device is powered by an external power source during operation. The second stepper motor drives the rotating roller to rotate slowly, which in turn drives the inner tank shell to rotate. The inner tank shell then drives the rotating mixing blades. At this time, the two mixing blades are close to the rotating roller, resulting in a smaller mixing range. As the mixing blades rotate, centrifugal force is applied, and the rotation speed of the second stepper motor shaft is controlled. Simultaneously, as the inner tank shell drives the mixing blades to rotate around the rotating roller, the mixing blades gradually rise. The mixing blades are rotatably connected inside the inner tank shell, rotating around one end of the inner tank shell. The mixing blades drive the double rotating arm rods, which are rotatably connected to one end of the mixing blades, to rotate. The double rotating arm rods rotate around one end of the mixing blades. When the double rotating arm is displaced, the upper limit seat of the double rotating arm rotating collar moves upward under the drive of the double rotating arm and is sleeved on the outside of the rotating roller. The collar squeezes the first spring, and the first spring deforms. At this time, the stirring blades gradually unfold and stir the raw materials in different areas inside the mixing cylinder to achieve full mixing of raw materials with different fluidity and heat resistance. The first step motor drives the gear to rotate, and the gear drives the outer toothed rotating cylinder to rotate. At this time, the solenoid valve on the lower inner side of the mixing cylinder is in the open state. The outer toothed rotating cylinder drives the inner fixed internal thread blade to rotate. The outer toothed rotating cylinder is connected to the inner side of the fixed plate and the mixing cylinder. When the internal thread blade rotates, it can transport the raw materials inside the mixing cylinder to the spinneret assembly. The bottom of the outer toothed rotating cylinder is in contact with the top of the wire outlet hole through the sealing ring.

[0018] S2: When changing different spinnerets, the servo motor is started, the servo motor spindle rotates and the adjustment plate rotates. The adjustment plate is rotatably connected to the inner side of the double column groove opened in the inner hollow machine box through the outer hollow column ring. The rotation of the adjustment plate drives the spinneret installed on the inner side to rotate. When the adjustment plate and the spinneret rotate, the outer toothed drum is kept in contact with the adjustment plate and the top of the adjustment plate through the sealing ring. When the specified spinneret is aligned with the feed cylinder and the outer toothed drum, the replacement of the spinneret can be completed.

[0019] S3: When disassembling and maintaining the spinneret assembly, the spinneret assembly to be disassembled is moved to the end near the operating port via a servo motor and adjustment disc. The spinneret assembly is operated from the operating port and inside the double-column groove. The designated electromagnet is activated, and the electromagnet magnetically attracts the cone clamp rod. Under the action of magnetic attraction, the cone clamp rod is housed inside the solid magnetic block groove. At the same time, the cone clamp rod compresses the second spring, causing the second spring to deform. At this time, the cone clamp rod moves away from the cone-shaped slot opened by the rectangular sliding plate and pushes the spinneret head upward from bottom to top. At this time, the spinneret head and the spinneret head can move away from the inside of the mounting groove. The rectangular sliding plate slides inside the square sliding groove. After setting the rectangular sliding plate and the square sliding groove, the new spinneret assembly is installed inside the mounting groove. The electromagnet is de-energized, and under the action of the second spring force, the cone clamp rod is pushed to move, and the cone clamp rod slides into the inside of the cone-shaped slot.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, the device achieves slow mixing of raw materials with different flowability and heat resistance inside the mixing cylinder through the configuration of an inner rotating shell, stirring blades, a mixing cylinder, a second stepper motor, and rotating rollers. This mixing method effectively limits the rotation range of the stirring blades through centrifugal force and precise control of the rotation speed of the second stepper motor spindle, thereby ensuring thorough mixing of raw materials in different areas. In addition, the displacement of the double rotating arms and the upward movement of the collar provide additional dynamic adjustments to the mixing process, ensuring uniform mixing of raw materials, improving mixing efficiency, and guaranteeing consistent product quality.

[0022] 2. In this invention, the rotation of the adjustment disc and the replacement of the spinneret are achieved through the setting of a servo motor, an adjustment disc, and a spinneret assembly. This design allows for rapid switching between different production units without disassembling the device, greatly improving the switching efficiency. This rapid switching function enables the device to adapt to the production needs of short fibers with different materials, cross-sectional shapes, and dyeing properties.

[0023] 3. In this invention, the electromagnet, conical locking rod, and magnetic block groove facilitate easy disassembly and maintenance of the spinneret assembly. The magnetic attraction of the electromagnet causes the conical locking rod to retract into the magnetic block groove, and the compression of the second spring by the conical locking rod causes deformation, thus facilitating the disassembly of the spinneret assembly. The pushing design of the spinneret head and the sliding design of the rectangular sliding plate within the square sliding groove provide precise limits for the installation and positioning of the spinneret assembly, preventing angular deviation after installation. After maintenance, the conical locking rod slides into the conical locking slot by de-energizing and the elastic force of the second spring, achieving rapid fixation of the spinneret assembly. This design significantly reduces maintenance time and minimizes the impact on short fiber production progress. Attached Figure Description

[0039] Please see Figure 1-8 The present invention provides a technical solution:

[0040] A composite spinneret based on differentiated short fibers and its usage method include a base 1 and a support 2. The support 2 is fixedly connected to the top of the base 1, and a changing box assembly 3 is fixedly connected to the top of the support 2.

The stirring assembly 4 includes a mixing cylinder 41, with a feeding port 42 on the inner side of the upper end of the mixing cylinder 41. A second stepper motor 44 is fixedly connected to the top of the mixing cylinder 41, and a rotating roller rod 45 is fixedly connected to the end of the main shaft of the second stepper motor 44.

A double rotating arm rod 43 is rotatably connected to one end of the stirring blade 47, and a first spring 48 is fixedly connected to the bottom end of the inner groove rotating shell 46. The bottom end of the 48 is fixedly connected to a collar 49. The chuck assembly 5 includes a servo motor 51. The end of the spindle of the servo motor 51 is fixedly connected to an adjustment plate 52. An internal mounting groove 53 is opened on the inner side of the adjustment plate 52. An outer hollow column ring 54 is fixedly connected to the outer side of the adjustment plate 52. A square sliding groove 55 is opened on the inner side of the adjustment plate 52.

A conical locking slot 64 is opened on the inner side of the rectangular sliding plate 63.

[0041] As a further implementation of this solution, the replacement box assembly 3 includes an inner hollow box 31. The inner hollow box 31 has a double-column groove 32 on its inner side. An operation port 33 is opened on the inner side of the left end of the inner hollow box 31. A fixed plate 34 is fixedly connected to the inner side of the inner hollow box 31. A first stepper motor 35 is fixedly connected to the top of the fixed plate 34. A limiting rotating hole is opened on the inner side of the fixed plate 34. The center of the limiting rotating hole of the fixed plate 34 is on the same vertical line as the center of the feeding cylinder 39. The operation port 33 is connected to the inside of the double-column groove 32. The opening diameter of the upper end of the double-column groove 32 is larger than that of the lower end to achieve structural stability. The alignment design of the limiting rotating hole on the inner side of the fixed plate 34 with the center of the feeding cylinder 39 ensures the precise positioning of the rotating parts. The connectivity between the operation port 33 and the double-column groove 32 and the gradual increase in the diameter of the upper end of the double-column groove 32 provide an effective channel for the flow and stirring of raw materials and reduce the resistance of raw material flow.

[0042] As a further implementation of this solution, the outer side of the mixing cylinder 41 is fixedly connected to the inner side of the double-column groove 32 opened in the inner hollow housing 31, the outer side of the adjusting plate 52 is rotatably connected to the inner side of the double-column groove 32 opened in the inner hollow housing 31 through the outer hollow column ring 54, and the top of the first stepper motor 35 is fixedly connected to the bottom of the mixing cylinder 41, so as to realize the function of quickly changing different production units, while maintaining the compactness of the device and the stability of the structure.

[0043] As a further implementation of this solution, a gear 36 is fixedly connected to the end of the main shaft of the first stepper motor 35. The outer side of the gear 36 meshes with the outer side of the external gear cylinder 37. An internal thread blade 38 is fixedly connected to the inner side of the external gear cylinder 37. A feed cylinder 39 is fixedly connected to the inner side of the hollow housing 31, which realizes precise transmission and positioning. The limiting rings at the upper and middle ends of the external gear cylinder 37 and the hollow design of the inner side of the external gear cylinder 37 provide space for solenoid valves and other control components, improving the functionality and flexibility of the device.

[0044] As a further implementation of this solution, the upper and middle ends of the external gear cylinder 37 are equipped with limiting rotating rings. The external gear cylinder 37 is rotatably connected to the inner side of the limiting rotating hole opened in the fixed plate 34. The inner side of the external gear cylinder 37 is hollow, and a gear ring is installed on the outer side of the external gear cylinder 37. The mixing cylinder 41 is provided with a limiting rotating hole on the inner side near the external gear cylinder 37. The limiting rotating hole of the mixing cylinder 41 is fitted with the outer side of the upper end of the external gear cylinder 37 through a sealing ring. A solenoid valve is installed on the inner side of the upper end of the limiting rotating hole of the mixing cylinder 41, which realizes precise control of the flow of raw materials, improves the controllability of the production process and the uniform mixing of raw materials.

[0045] As a further implementation of this solution, the spinneret 61 and the wire outlet 62 slide on the outside of the mounting groove 53. The rectangular slide plate 63 is a slotted rectangle and slides on the inside of the square sliding groove 55. The number of rectangular slide plates 63 corresponds one-to-one with the number of square sliding grooves 55. The mounting groove 53 is shaped like a cylinder at both ends and passes through the interior of the adjusting plate 52. The outer hollow cylindrical ring 54 is a hollow cylinder. The cone clamp rod 59 slides on the inside of the cone clamp 64. The cone clamp 64 is shaped like a cone. These designs provide a flexible component adjustment and positioning mechanism, making the installation and maintenance of the spinneret assembly 6 more convenient and faster.

[0046] As a further implementation of this scheme, the rotating roller rod 45 is rotatably connected to the inner side of the mixing cylinder 41, the collar 49 is a hollow cylinder, the collar 49 is sleeved on the outer side of the rotating roller rod 45, a limiting seat is installed at the upper end of the collar 49, a limiting seat is installed on one side of the stirring blade 47, and the first spring 48 is sleeved on the outer side of the rotating roller rod 45, providing an effective stirring and movement mechanism, and through precise limiting and deformation control, ensuring the uniformity of the stirring process and the full mixing of the raw materials.

[0047] Working process: When mixing raw materials with different flowability and heat resistance inside the mixing cylinder 41, the device is powered on by an external power source during operation, starting the second stepper motor 44. The second stepper motor 44 drives the rotating roller 45 to rotate slowly, which in turn drives the inner tank rotating shell 46 to rotate. The inner tank rotating shell 46 then drives the rotatingly connected stirring blades 47 to rotate. At this time, the two stirring blades 47 are close to the rotating roller 45, and the stirring range of the stirring blades 47 is relatively small. As the stirring blades 47 rotate, under the action of centrifugation, the rotation speed of the main shaft of the second stepper motor 44 is simultaneously controlled. At this time, the inner tank rotating shell 46 drives the stirring blades 47 to rotate at a speed of... When the rotating roller rod 45 rotates around its axis, the stirring blade 47 gradually rises. The stirring blade 47 is rotatably connected to the inside of the inner trough rotating shell 46. The stirring blade 47 rotates around one end of the inner trough rotating shell 46, which limits the rotation range of the stirring blade 47. The stirring blade 47 drives the double rotating arm rod 43, which is rotatably connected at one end, to rotate. The double rotating arm rod 43 rotates around one end of the stirring blade 47, and at the same time, the double rotating arm rod 43 is displaced. The double rotating arm rod 43 rotates inside the limiting seat at the upper end of the rotating collar 49. Driven by the double rotating arm rod 43, the collar 49 moves upward. The collar 49 is fitted onto the outside of the rotating roller rod 45, which serves to limit the collar. When the collar 49 moves, it acts as a limit stop. The collar 49 compresses the first spring 48, causing the first spring 48 to deform and reset the collar 49. At this time, the stirring blades 47 gradually unfold, stirring the raw materials in different areas inside the mixing cylinder 41. This achieves thorough mixing of raw materials with different fluidities and heat resistances. During stirring, different stirring zones can be switched, and floating or settled raw materials can be agitated, thereby quickly mixing raw materials with different fluidities, improving product mixing efficiency, ensuring uniform quality at the limit stop, and starting the first stepper motor 35. The first step motor 35 drives the gear 36 to rotate, and the gear 36 drives the external gear drum 37 to rotate. At this time, the solenoid valve on the inner side of the lower part of the mixing cylinder 41 is in the open state. The external gear drum 37 drives the internal thread blade 38 fixed on the inner side to rotate. The external gear drum 37 is rotatably connected to the inner side of the fixed plate 34 and the mixing cylinder 41. When the internal thread blade 38 rotates, the raw material is put into the inside of the mixing cylinder 41 from the feeding port 42. The raw material inside the mixing cylinder 41 can be transported to the inside of the spinneret 6. The bottom end of the external gear drum 37 is fitted with the top end of the yarn outlet 62 through the sealing ring to prevent the raw material from overflowing. The raw material passes through the yarn outlet 62, thereby realizing the production of short fibers.

[0048] When changing different spinnerets 6, the servo motor 51 is started, the spindle of the servo motor 51 rotates and the adjusting plate 52 rotates. The adjusting plate 52 is rotatably connected to the inner side of the double column groove 32 opened in the inner hollow machine box 31 through the outer hollow column ring 54, which plays a role in limiting the rotation of the adjusting plate 52. The rotation of the adjusting plate 52 drives the spinneret 6 installed on the inner side to rotate. When the adjusting plate 52 and the spinneret 6 rotate, the outer toothed drum 37 is kept in contact with the adjusting plate 52 and the top of the adjusting plate 52 through the sealing ring. When the specified spinneret 6 is aligned with the feed cylinder 39 and the outer toothed drum 37, the replacement of the spinneret 6 can be completed. The replacement process is convenient and quick, without the need to disassemble the device. It is suitable for the production of short fibers with different materials, different cross-sectional shapes and different dyeing properties.

[0049] When disassembling and maintaining the spinneret assembly 6, the spinneret assembly 6 to be disassembled is moved to the end near the operating port 33 via the servo motor 51 and the adjusting plate 52. The spinneret assembly 6 is operated from inside the operating port 33 and the double-column groove 32. The designated electromagnet 57 is activated, and the electromagnet 57 magnetically attracts the conical locking rod 59. Under the action of magnetic attraction, the conical locking rod 59 is housed inside the solid magnetic block groove 56. At the same time, the conical locking rod 59 compresses the second spring 58, causing the second spring 58 to deform and reset the conical locking rod 59. At this time, the conical locking rod 59 moves away from the conical locking slot 64 opened in the rectangular sliding plate 63 and pushes the spinneret head 61 upward from bottom to top. When the spinneret 61 is moved, it can move away from the interior of the mounting groove 53. The rectangular slide plate 63 slides inside the square sliding groove 55. The rectangular slide plate 63 and the square sliding groove 55 are set to limit the spinneret assembly 6 during installation, preventing the spinneret assembly 6 from tilting after installation. Then, the new spinneret assembly 6 is installed inside the interior of the mounting groove 53. The electromagnet 57 is de-energized. Under the action of the second spring 58, the cone clamp rod 59 is pushed to move. The cone clamp rod 59 slides into the cone clamp 64, thereby fixing the spinneret assembly 6. This makes maintenance of the spinneret assembly 6 convenient and quick, and reduces the impact on the short fiber production progress.

The second stepper motor (44) drives the rotating roller (45) to rotate slowly. The rotating roller (45) drives the inner tank shell (46) to rotate. The inner tank shell (46) drives the rotating and connected stirring blades (47) to rotate. At this time, the two stirring blades (47) are close to the rotating roller (45). At this time, the stirring range of the stirring blades (47) is small. When the stirring blades (47) rotate, the stirring range is small. Under the action of the heart, the rotation speed of the main shaft of the second stepper motor (44) is controlled simultaneously. At this time, when the inner tank rotating shell (46) drives the stirring blade (47) to rotate around the rotating roller (45) as the axis, the stirring blade (47) gradually rises. The stirring blade (47) is rotatably connected to the inside of the inner tank rotating shell (46). The stirring blade (47) rotates around one end of the inner tank rotating shell (46) as the axis. The stirring blade (47) drives the double rotating arm (43) connected to one end to rotate. The double rotating arm (43) rotates around one end of the stirring blade (47). As the axis rotates, the double rotating arm (43) is displaced. Driven by the double rotating arm (43), the collar (49) moves upward. The collar (49) is fitted onto the outside of the rotating roller (45). The collar (49) compresses the first spring (48), causing the first spring (48) to deform. At this time, the stirring blade (47) gradually unfolds.
