Description

Technical Field

[0001] This utility model relates to the field of fiber spinning technology, specifically to a parallel spinning nozzle device for forming hollow high-elastic fibers. Background Technology

[0002] Hollow high-elastic fiber is widely used in home textiles, sportswear and other fields because it combines lightweight and fluffy texture with excellent resilience. Its forming relies on a parallel spinning nozzle device. This device extrudes two different melts (such as high-elastic component and support component) through the spinneret and forms a hollow structure with the help of a mandrel. It is the core equipment that determines the fiber performance. The nozzles need to be frequently changed to match different fiber specifications. The efficiency and stability of the replacement directly affect the continuity of production.

[0003] However, the existing nozzles and main body use a multi-bolt fixing structure, which requires special tools for disassembly and installation, and the replacement takes a long time, affecting the efficiency of continuous production. In addition, frequent disassembly and assembly can easily cause wear on the sealing surface, and the melt leakage rate increases with the number of replacements, which not only increases raw material loss, but may also cause equipment safety hazards. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a parallel spinning nozzle device for hollow high-elastic fiber forming to solve the problems mentioned in the background art. This invention has a novel structure. By setting a limiting mechanism and a sleeve in a coordinated structure, the limiting mechanism drives the extrusion block through a screw to engage the U-shaped connecting rod. Combined with the elastic clamping of the L-shaped rocker plate and spring, it achieves dual rapid locking and convenient disassembly of the spinning nozzle. This not only improves the fiber forming accuracy caused by nozzle loosening due to vibration, but also shortens the disassembly and assembly time during maintenance, and improves the continuous operation efficiency of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a parallel spinning nozzle device for hollow high-elastic fiber forming, comprising a positioning plate, two support frames fixedly connected to the upper side of the positioning plate, a motor mounted on the upper side of the support frames, a threaded rod fixedly connected to the output end of the motor, a lifting seat threadedly fitted on the threaded rod, a feeding pump mounted on the upper side of the lifting seat, a winding assembly disposed on the upper side of the positioning plate between the two support frames, a spinning nozzle disposed on one side of the lifting seat, an installation groove provided on one side of the lifting seat, a sleeve cooperating with the spinning nozzle fixedly connected to the inner wall of the installation groove, and a limiting mechanism cooperating with the sleeve disposed inside the installation groove.

[0006] Furthermore, the lifting seat is slidably fitted on one side of the support frame, and the lower end of the threaded rod is rotatably fitted with the support frame.

[0008] Furthermore, the two U-shaped connecting rods are symmetrically arranged, and one end of the U-shaped connecting rod is engaged with the snap-fit ​​groove through the outer opening of the sleeve. The two limiting plates are arranged on the outer side of the U-shaped connecting rod.

[0009] Furthermore, both sides of the sleeve are rotatably fitted with L-shaped rockers, and springs are installed on opposite sides of the two L-shaped rockers, with opposite ends of the two springs fixedly connected to the sleeve.

[0010] Furthermore, a ring block is fixedly connected to the outside of the spinning nozzle, and slots are provided on both sides of the ring block. One end of the L-shaped rocker plate is engaged with the slot.

[0011] Furthermore, a trapezoidal guide groove is fixedly connected to the upper side of the spinning nozzle, and a trapezoidal protrusion adapted to the trapezoidal guide groove is provided on the upper side of the inner wall of the sleeve.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please refer to Figures 1 to 6This utility model provides a technical solution: a parallel spinning nozzle device for hollow high-elastic fiber molding, comprising a positioning plate 1, two support frames 2 fixedly connected to the upper side of the positioning plate 1, a motor 3 mounted on the upper side of the support frames 2, a threaded rod 4 fixedly connected to the output end of the motor 3, a lifting seat 5 threadedly fitted on the threaded rod 4, a feed pump 6 mounted on the upper side of the lifting seat 5, a winding assembly 7 disposed on the upper side of the positioning plate 1 between the two support frames 2, a spinning nozzle 8 disposed on one side of the lifting seat 5, an installation groove 9 opened on one side of the lifting seat 5, a sleeve 10 cooperating with the spinning nozzle 8 fixedly connected to the inner wall of the installation groove 9, and a limiting mechanism 11 cooperating with the sleeve 10 disposed inside the installation groove 9. The lifting seat 5 is slidably fitted on one side of the support frame 2, and the lower end of the threaded rod 4 is rotatably fitted with the support frame 2. The positioning plate 1 is fixed as a whole by the positioning grooves 16 at the four corners. The motor 3 drives the threaded rod 4 to rotate, which drives the lifting seat 5 to slide up and down along the support frame 2 to adjust the height of the spinning nozzle 8. The feed pump 6 delivers the raw material to the spinning nozzle 8. The formed fiber is collected by the winding assembly 7 between the two support frames 2. The spinning nozzle 8 is installed in the mounting groove 9 of the lifting seat 5 by the sleeve 10 and fixed by the limiting mechanism 11. The spinning height is adjustable by the cooperation of the motor 3 and the threaded rod 4 to adapt to different process requirements. The winding assembly 7 realizes the continuous collection of fiber and improves production efficiency. The cooperation of the sleeve 10 and the limiting mechanism 11 ensures that the spinning nozzle 8 is installed stably and avoids shaking that affects the forming accuracy.

[0025] In this embodiment, the limiting mechanism 11 includes a lead screw 111 rotatably fitted to the lower side of the lifting seat 5. U-shaped connecting rods 112 are rotatably fitted to both sides of the inner wall of the mounting groove 9. A pressing block 113 is threaded onto the upper end of the lead screw 111. A mating groove 114 is provided at one end of each U-shaped connecting rod 112 near the pressing block 113, and the pressing block 113 mates with the mating groove 114. Limiting plates 115 are fixedly connected to both sides of the pressing block 113. A knob 116 is fixedly connected to the lower end of the lead screw 111. A locking groove 117 is symmetrically provided on the outer side of the spinning nozzle 8. The two U-shaped connecting rods 112 are symmetrically arranged, and one end of each U-shaped connecting rod 112 is locked into the locking groove 117 through the outer opening of the sleeve 10. The two limiting plates 115 are located on the outer side of the U-shaped connecting rods 112. Rotating knob 116 drives screw 111 to rotate, causing extrusion block 113 to move downwards. Extrusion block 113 presses against mating groove 114, causing U-shaped connecting rod 112 to rotate around the inner wall of mounting groove 9. One end of U-shaped connecting rod 112 is inserted into the locking groove 117 of spinning nozzle 8 through the outer opening of sleeve 10, thus completing the locking. Rotating knob 116 in the opposite direction can release the fixation. The spinning nozzle 8 can be quickly disassembled and securely locked through mechanical transmission. Limiting plate 115 is used to limit the extrusion block 113, allowing it to move up and down. Knob 116 is easy to operate, reducing the difficulty of disassembly and assembly during maintenance and improving the flexibility of the equipment.

[0026] In this embodiment, L-shaped rocker arms 12 are rotatably fitted on both sides of the sleeve 10. Springs 13 are installed on opposite sides of each L-shaped rocker arm 12, and opposite ends of each spring 13 are fixedly connected to the sleeve 10. A ring block 14 is fixedly connected to the outer side of the spinning nozzle 8. Slots 15 are provided on both sides of the ring block 14, and one end of each L-shaped rocker arm 12 engages with a slot 15. A trapezoidal guide groove 17 is fixedly connected to the upper side of the spinning nozzle 8, and a trapezoidal protrusion 18, matching the trapezoidal guide groove 17, is provided on the upper side of the inner wall of the sleeve 10. Multiple positioning slots 16 are provided on the upper side of the positioning plate 1, and these slots are located at the four corners of the positioning plate 1. When the spinning nozzle 8 is installed, its outer trapezoidal guide groove 17 cooperates with the trapezoidal protrusion 18 on the inner wall of the sleeve 10 to achieve precise positioning. At the same time, the ring block 14 squeezes the L-shaped rocker plate 12, and the spring 13 is compressed under force. When the slot 15 of the ring block 14 is aligned with the L-shaped rocker plate 12, the spring 13 resets and pushes the L-shaped rocker plate 12 into the slot 15, forming a secondary fixation. When it is necessary to unlock the ring block 14, press the end of the L-shaped rocker plate 12 to make the L-shaped rocker plate 12 rotate, thereby separating it from the slot 15 and contacting the limit. The elastic snap-fit ​​structure composed of the L-shaped rocker plate 12 and the spring 13 adds double fixation on the basis of the limit mechanism 11, further improving the connection stability, while buffering the vibration during the spinning process.

[0027] When using the device, the overall structure is fixed by the positioning groove 16 of the positioning plate 1. The motor 3 drives the threaded rod 4 to drive the lifting seat 5 to adjust the height along the support frame 2, so that the spinning nozzle 8 is in a suitable working position. The feed pump 6 delivers the raw material to the spinning nozzle 8. The formed hollow high-elastic fiber is collected by the winding assembly 7. The installation of the spinning nozzle 8 adopts a multi-positioning and fixing mechanism. The trapezoidal guide groove 17 and the trapezoidal protrusion 18 achieve initial positioning. Rotating the knob 116 causes the U-shaped connecting rod 112 of the limiting mechanism 11 to engage with the locking groove 117, completing the mechanical locking. At the same time, the L-shaped rocker plate 12 engages with the locking groove 15 of the ring block 14 under the action of the spring 13, forming an elastic auxiliary fixation to ensure the stability of the nozzle. Through the coordinated design of adjustable height, quick disassembly and assembly, and multiple fixation, the device can adapt to different process parameter requirements, ensure the stability of the spinning process and the quality of fiber forming, and improve production efficiency and maintenance convenience.
