Description

Technical Field

[0001] The utility model relates to the technical field of spinneret assembly, in particular to a spinneret assembly which is easy to adjust. Background Art

[0002] The spinneret assembly is one of the core components of meltblown cloth manufacturing, which includes spinnerets, air knives and other components. The spinneret is usually located in the spinneret hole part of the melt spinning equipment, which is used to eject the molten raw materials in the form of filaments. The air knife is responsible for stretching the filaments in the air and forming a cloth shape through airflow adjustment and orientation after the filaments are formed. Among them, the relative gap between the spinneret and the air knife directly determines the quality of the product. In actual applications, operators need to adjust the relative gap between the spinneret and the air knife to adapt to different product requirements.

[0003] After searching, the utility model patent with publication number CN212533211U discloses a modular standardized spinneret, which is equipped with structures such as an adjusting valve, a fixed seat, and a guide column. According to usage requirements, the operator can rotate the adjusting valve so that part of the wind knife plate slides and deforms along the guide column as the thread rotates, thereby changing the gap size of the air outlet, eliminating the use of gaskets, and making the operation convenient and quick.

[0004] However, the mold base and the air knife plate are connected and fixed by multiple sets of regulating valves, and the regulating valves and the air knife plate are all threaded. In order to achieve the movement of the air knife plate, the operator needs to turn multiple sets of regulating valves at the same time and ensure that the rotation angles of the multiple sets of regulating valves are consistent, which makes the operation very complicated. Secondly, the size of the air outlet between the air knife plates needs to be adjusted accurately to 0.1mm. This means that during the adjustment process, the operator needs to use a feeler gauge to measure the size of the air outlet in sections and make frequent adjustments to ensure accurate adjustment. This process is time-consuming and labor-intensive. Utility Model Content

Ten groups of circular grooves 533 are equidistantly opened on the round cover 53, and the diameter of the circular groove 533 is smaller than the diameter of the limiting ball 523. A limiting plate 55 is slidably sleeved on the outside of the threaded adjustment rod 4, and ten groups of limiting holes 551 matching the limiting ball 523 are equidistantly opened on the limiting plate 55. A thick spring 56 is fixedly connected between the limiting plate 55 and the hexagonal head 42. The inside of the limiting groove 13 is detachably connected with a guide assembly 6, and the guide assembly 6 includes a limiting block 61 and an insert block 63. The limiting block 61 is movably connected to the inside of the limiting groove 13, and the insert block 63 is fixedly connected to the side of the limiting block 61 close to the wind knife 2.The plug block 63 is slidably connected to the C-shaped seat 23, and a connecting plate 62 is fixedly connected to the side of the limit block 61 away from the plug block 63, and the connecting plate 62 is fixedly connected to one side of the spinneret body 1 by bolts.

[0029] Among them, the pitch of the threaded adjustment rod 4 is 1mm, which means that when the threaded adjustment rod 4 rotates one circle, it will move a distance of 1mm along the axial direction (the movement distance of the threaded adjustment rod 4 is equal to the movement distance of the wind knife 2). Secondly, there are ten groups of limit holes 551 on the limit plate 55. These limit holes 551 cooperate with the limit balls 523 to accurately control the tiny movements of the threaded adjustment rod 4. When the threaded adjustment rod 4 drives the limit plate 55 to rotate, each time the limit hole 551 is aligned with the limit ball 523, it means that the threaded adjustment rod 4 has moved a distance of 0.1mm along the axis. This design determines and controls the tiny movements of the threaded adjustment rod 4 by aligning the limit holes 551 and the limit balls 523, so that the movement amount can be accurate to 0.1mm.

[0030] The utility model can drive the wind knife 2 to move by rotating the threaded adjustment rod 4, so as to achieve the purpose of adjusting the distance between the spinneret body 1 and the wind knife 2. Specific operation process: rotate the hexagonal head 42 by a wrench, the hexagonal head 42 drives the threaded adjustment rod 4 to rotate, and the threaded adjustment rod 4 drives the limit plate 55 to rotate. As the threaded adjustment rod 4 continues to go deeper, the elastic force of the thick spring 56 will make the limit plate 55 always contact with the surface of the round cover 53 to ensure that the limit hole 551 and the limit ball 523 are always in a state of mutual cooperation. Secondly, when it is necessary to disassemble the spinneret body 1 and the wind knife 2, it is necessary to first remove the bolts used to fix the connecting plate 62 and the spinneret body 1, and take the plug 63 out of the C-shaped seat 23. Then remove the bolts used to fix the fixing plate 41 and the wind knife 2, and finally remove all the fixing bolts 211, so that the disassembly of the spinneret body 1 and the wind knife 2 is completed.

[0031] Specifically, if Figure 4 As shown, the diameter of the fixing hole 21 is larger than the diameter of the connecting hole 11 (the diameter difference can be determined according to the adjustment range corresponding to the production requirements). The purpose of this design is that the wind knife 2 and the spinneret body 1 can be fine-tuned under the premise that they are fixed by the fixing bolt 211. The wind knife 2 and the spinneret body 1 are connected by the fixing bolt 211. The specific connection method is: the screw of the fixing bolt 211 passes through the fixing hole 21 and the connecting hole 11, and the screw of the fixing bolt 211 is threadedly connected to the connecting hole 11, and the head of the fixing bolt 211 abuts against the recessed groove of the fixing hole 21 (the upper surface of the fixing hole 21 is provided with a recessed groove for accommodating the head of the fixing bolt 211).

[0032] Specifically, the diameter of the circular groove 533 is smaller than the diameter of the limiting ball 523. The purpose of such a setting is to limit the position of the limiting ball 523 by the circular groove 533, so that the limiting ball 523 is always in contact with the circular groove 533 under the elastic action of the thin spring 521. A circular ring 522 is also provided between the limiting ball 523 and the thin spring 521, and the limiting ball 523 can rotate freely inside the circular ring 522.

[0033] Specifically, when the threaded adjustment rod 4 is rotated, the wind knife 2 will undergo a corresponding displacement change. During this process, the plug block 63 slides inside the C-shaped seat 23, and the sliding of the plug block 63 and the C-shaped seat 23 plays a positioning and guiding role, so that the wind knife 2 can only slide along the guide path of the C-shaped seat 23.

[0034] Furthermore, two groups of positioning blocks 12 are fixedly connected to the left and right sides of the spinneret body 1 , and positioning grooves 22 matching with the positioning blocks 12 are provided at both ends of one side of the wind knife 2 .

[0035] Specifically, when assembling the spinneret body 1 and the wind knife 2, it is only necessary to align the positioning groove 22 with the positioning block 12, thereby reducing the time required for positioning, making the installation more convenient and less time-consuming.

[0036] Furthermore, a through hole 231 is formed on the upper surface of the C-shaped seat 23 , and a locking bolt 232 is connected to the internal thread of the through hole 231 . A top groove 631 is formed on the upper surface of the insert block 63 , and the lower end of the locking bolt 232 passes through the through hole 231 and abuts against the top groove 631 .

[0037] Specifically, after the position adjustment of the wind knife 2 is completed, the locking bolt 232 can be tightened. At this time, the lower end of the locking bolt 232 abuts against the top groove 631, thereby achieving relative fixation of the C-shaped seat 23 and the insert block 63.

[0038] Furthermore, guide rail grooves 233 are provided on both sides of the C-shaped seat 23 , and rollers 64 are rotatably connected to both sides of the insert block 63 , and the rollers 64 are slidably connected to the inside of the guide rail grooves 233 .

[0039] Specifically, when adjusting the position of the wind knife 2, the plug block 63 slides inside the C-shaped seat 23. During the sliding process, the rollers 64 on both sides of the plug block 63 slide along the guide grooves 233 inside the C-shaped seat 23. The sliding of the rollers 64 makes the movement of the plug block 63 inside the C-shaped seat 23 smoother and more stable, reduces friction, and makes the adjustment process of the wind knife 2 easier.

[0040] Furthermore, a guide groove 43 is provided on the outer side of the threaded adjustment rod 4 and at one end close to the hexagonal head 42 , and a guide block 552 is fixedly connected to the inner side of the limiting plate 55 , and the guide block 552 is slidably connected to the inside of the guide groove 43 .

[0041] Specifically, on the one hand, the guide groove 43 limits the guide block 552, thereby ensuring that the limit plate 55 can rotate synchronously with the threaded adjustment rod 4. On the other hand, the guide block 552 can slide inside the guide groove 43 along the path of the guide groove 43, thereby ensuring that the limit plate 55 can always keep in contact with the round cover 53 under the elastic force of the thick spring 56.

[0042] Furthermore, the cylindrical seat 51 is provided with a side hole 1 511 on both the front and rear sides, and the round cover 53 is provided with a side hole 2 531 on both the front and rear sides. The side hole 2 531 is movably connected inside with a side bolt 54 , which passes through the side hole 2 531 and is threadedly connected to the side hole 1 511 .

[0043] Specifically, the round cover 53 is fixed to the cylindrical seat 51 by means of side bolts 54. When the elastic limiter 52 inside the mounting groove 513 is damaged or needs to be replaced, the round cover 53 can be removed for timely maintenance and replacement.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
