Description
Technical Field
[0001] This utility model relates to the field of fiber manufacturing equipment technology, specifically to a manufacturing equipment for sanitary napkin raw material fibers. Background Technology
[0002] Sanitary napkins require multiple processes during production, with fiber forming of the raw materials being the most crucial step. Fiber forming equipment typically includes wet spinning machines and dry spinning machines, with wet spinning machines being the most common type of equipment.
[0003] In the prior art, wet spinning machines typically include a spinning solution supply system, spinning components, a bath, a traction and winding system, etc. After being precisely metered, mixed, stirred, filtered and degassed in the supply system, the spinning solution is transported to the spinning components. At the spinning nozzle, the solution is extruded through the spinneret to form a fine stream that enters the bath. The coagulating bath liquid in the bath causes the fiber to coagulate. Subsequently, the traction device draws out the fiber, the stretching device stretches it to improve its strength and modulus, and finally the winding device winds the stretched fiber into a roll.
[0004] However, when the filaments extruded from the spinneret enter the coagulation bath, they have a certain speed and momentum, which can easily directly impact the bottom of the bath or other components, thereby damaging the initial morphology of the fibers, such as causing fiber breakage, deformation, or uneven surface.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Example 1
[0024] Please see Figures 1 to 2 This utility model provides a technical solution: a manufacturing equipment for sanitary napkin raw material fibers, including an equipment body 1, a storage tank 2 is provided on the surface of the equipment body 1, a spinning nozzle 3 is provided at one end of the storage tank 2, a bath 4 is provided on the surface of the equipment body 1, support rods 5 are fixedly connected to both sides of the surface of the bath 4, a connecting plate 12 is slidably connected to the surface of the support rods 5, a buffer plate 6 is rotatably connected between the two connecting plates 12, a limiting plate 16 is provided on the surface of one end of the buffer plate 6, a clamping plate 17 is provided on the surface of one connecting plate 12, and the limiting plate 16 is clamped to the surface of the clamping plate 17;
[0025] A buffer plate 6 is installed inside the bath 4, which can effectively slow down the speed of the fibers when they enter the bath 4, change the direction of fiber movement, and make the fibers evenly distributed in the bath 4. This reduces the entanglement or collision between fibers with the walls of the bath 4, and improves the quality of the fibers. Through the cooperation of the limiting plate 16 and the clamping plate 17, as well as the cooperation between the manual screw 8 and the support rod 5, the height and angle of the buffer plate 6 can be adjusted, so that the equipment can adapt to different production process requirements and fiber characteristics, thereby improving the versatility and production efficiency of the equipment.
[0026] Example 2
[0027] Please see Figures 1 to 4Based on Embodiment 1, in order to adjust the height of the buffer plate 6, an auxiliary rod 7 is fixedly connected to the surface of one support rod 5. The auxiliary rod 7 can ensure that the connecting plate 12 moves along a specific straight line direction, avoiding any deviation or shaking, and improving the stability of the entire adjustment structure. A manual screw 8 is rotatably connected to the surface of another support rod 5. One end of the manual screw 8 extends through to the top surface of the support rod 5 and is fixedly connected to a handwheel 11. The operator only needs to manually turn the handwheel 11 to easily control the rotation of the manual screw 8, thereby realizing the adjustment of the height of the buffer plate 6.
[0028] The connecting plate 12 has an "L"-shaped plate structure. Threaded holes 9 are formed on the surface of the connecting plate 12. The auxiliary rod 7 passes through the surface of one threaded hole 9, and the other threaded hole 9 is matched and connected to the threaded part on the surface of the manual lead screw 8. Square grooves 15 are formed on the surfaces of the two connecting plates 12 that are far apart from each other. Three central rods 10 are fixedly connected to the surface of one square groove 15. The central rods 10 have a "T"-shaped circular plate structure. The central rods 10 provide stable support and precise guidance for the springs 14 sleeved on their surfaces. During the compression and extension of the springs 14, the central rods 10 can effectively limit the radial displacement of the springs 14, ensuring that the springs 14 always move smoothly along the axial direction. The length of the central rods 10 is less than the groove depth of the square grooves 15, preventing one end of the central rods 10 from contacting the inner wall of the bath 4. The springs 14 are sleeved on the surface of the central rods 10. The springs 14 are in their initial state, that is, in a pre-compressed state after installation, to ensure that the clamping plate 17 and the limiting plate 16 are tightly engaged.
[0029] Example 3
[0030] Please see Figures 1 to 5 Based on Embodiment 2, in order to adjust the angle of the buffer plate 6, one end of the spring 14 is fixedly connected to the surface of the square groove 15, and the other end of the spring 14 is fixedly connected to the surface of the clamping plate 17. When the spring 14 is in the initial state, it can provide continuous pressure to the clamping plate 17, so that the groove on the surface of the clamping plate 17 is tightly engaged with the teeth on the surface of the limiting plate 16, preventing the buffer plate 6 from changing its angle due to accidental vibration and ensuring the stability of the fiber buffering process.
[0031] The clamping plate 17 has an arc-shaped plate structure, and the surface of the clamping plate 17 is provided with multiple toothed grooves. The buffer plate 6 has a square plate structure, and the two ends of the buffer plate 6 are fixedly connected to the rotating shafts 13. The rotating shafts 13 are rotatably connected to the circular holes opened on the surface of the connecting plate 12. The limiting plate 16 is fixedly connected to the surface of one of the rotating shafts 13. The surface of the connecting plate 12 is provided with multiple teeth arranged in a circumferential array. The outer ring surface of the limiting plate 16 is provided with multiple teeth arranged in a circumferential array. The teeth and the toothed grooves on the surface of the clamping plate 17 mesh with each other to limit the buffer plate 6.
[0032] In actual use, the spinning solution stored in the storage tank 2 is squeezed out through the spinning nozzle 3 and falls into the bath 4. The bath 4 is filled with coagulated bath liquid. The buffer plate 6 forms a certain angle with the bottom of the bath 4. After the spinning solution enters the bath 4, it comes into contact with the buffer plate 6, so that the fiber can slide more smoothly into the bath 4, avoiding damage or tangling of the fiber due to impact.
[0033] When the height of the buffer plate 6 needs to be adjusted, the operator first turns the handwheel 11, which drives the manual screw 8 to rotate. The manual screw 8 is matched and connected with the threaded hole 9 on the connecting plate 12. The rotation of the manual screw 8 causes the two connecting plates 12 to slide along the surface of the support rod 5. The two connecting plates 12 drive the buffer plate 6 to move synchronously, thereby realizing the adjustment of the height of the buffer plate 6 and adapting to different spinning process requirements.
[0034] When the angle of the buffer plate 6 needs to be adjusted, turn the handwheel 11 to place the buffer plate 6 completely on the upper end of the bath 4, and then press the clamping plate 17. The clamping plate 17 compresses the spring 14 from the initial state to the compressed state, and the teeth on the surface of the clamping plate 17 separate from the teeth on the surface of the limiting plate 16. At this time, the buffer plate 6 can rotate freely around the rotating shaft 13. After the operator adjusts the angle of the buffer plate 6, release the clamping plate 17, the spring 14 returns to its original deformation, pushes the clamping plate 17 to reset, and makes the teeth on the surface of the clamping plate 17 mesh with the teeth on the outer ring surface of the limiting plate 16 again, thereby limiting the buffer plate 6 and fixing the adjusted angle.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
