Description

Technical Field

[0001] The invention relates to winding of meltblown nonwoven fabrics, and more specifically, to a winding device for producing meltblown nonwoven fabrics. Background Art

[0002] Meltblown nonwoven fabric is a nonwoven fabric made of polypropylene as the main raw material. Its production process includes the feeding of polymer resin chips, melt extrusion, melt impurity filtration, precise metering by metering pump, spinning, web forming, trimming and winding, and product post-processing. During the spinning process, the polymer melt is extruded from the die spinneret hole to form a melt stream. At the same time, the high-speed and high-temperature airflow on both sides of the spinneret hole blows and stretches the melt stream, thereby refining it into filaments with a fineness of only 1 to 5 μm. These filaments are then broken into short fibers by the hot air flow and made into meltblown nonwoven fabrics by self-adhesion. Meltblown nonwoven fabric winding is a key step in the meltblown nonwoven production process and is located at the end of the production line. It is mainly responsible for winding the produced meltblown nonwoven fabric into rolls for subsequent processing and storage;

[0003] However, the current existing technology already has the following problems: after the winding roller used in the meltblown non-woven fabric winding device has finished winding the fabric, it is necessary to disassemble the winding roller and the wound fabric, and this step requires manual disassembly of the wound fabric, resulting in excessive waste of disassembly and installation time, which is easy to reduce work efficiency and has certain limitations.

Detailed implementation manners

[0041] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0042] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0043] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0044] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0045] like Figures 1 - 15 As shown, a winding device for producing meltblown nonwoven fabrics includes a winding table 1 and a fabric tensioning mechanism 2, wherein the fabric tensioning mechanism 2 is arranged at one end of the upper surface of the winding table 1, and further includes:

[0046] Multiple groups of winding rollers 3, a side mounting plate 7 is provided at the other end of the upper surface of the winding platform 1, the multiple groups of winding rollers 3 are arranged in a ring-shaped and equidistant manner on one side of the side mounting plate 7, the winding rollers 3 are arranged corresponding to the fabric tensioning mechanism 2, the winding rollers 3 are composed of multiple groups of winding mechanisms spliced ​​together, and the multiple groups of winding mechanisms are detachably arranged from each other;

[0047] like Figures 1 to 15 As shown, by designing that the winding roller 3 is composed of multiple groups of winding mechanisms, the length of the winding roller 3 can be arbitrarily composed, so that it can be adjusted accordingly according to the width requirements of the fabric, thereby further improving the practicality of the winding equipment.

[0048] A fabric loosening mechanism 4, wherein the fabric loosening mechanism 4 is provided with multiple groups, and the fabric loosening mechanism 4 is provided in pairs with the winding roller 3, a support column 6 is provided at the other end of the upper surface of the winding platform 1, and the support column 6 is provided corresponding to the side mounting plate 7, and the fabric loosening mechanism 4 is detachably connected to the winding roller 3;

[0049] The bending assembly 5 is provided with multiple groups, and the bending assembly 5 is provided in pairs with the fabric loosening mechanism 4, and the bending assembly 5 is transmission-connected with the fabric loosening mechanism 4, so that the fabric loosening mechanism 4 is rotated toward or away from the winding roller 3 through the bending assembly 5.

[0050] Further, the winding mechanism includes multiple groups of arc-shaped plates 301 and positioning sleeves 303. The multiple groups of arc-shaped plates 301 are combined to form a cylinder. The multiple groups of arc-shaped plates 301 are arranged in a mutually engaging manner, and the multiple groups of arc-shaped plates 301 are all movably connected to the positioning sleeve 303;

[0051] As Figures 1 to 15 shown, through the design of combining multiple groups of arc-shaped plates 301 to form a cylinder, the multiple groups of arc-shaped plates 301 can be combined into a shorter winding roller 3. And there are multiple groups of winding mechanisms, and they can be spliced with each other, so that winding rollers 3 of different lengths can be combined to form, making it convenient to target non-woven fabrics of different widths, thus effectively improving the practicability of the winding equipment.

[0052] Further, the arc-shaped plate 301 is composed of a neutral plate 3011 and two groups of side plates 3012. The neutral plate 3011 is located between the two groups of side plates 3012, and a linkage plate 9 is arranged between the neutral plate 3011 and the side plate 3012. Thus, the side plate 3012 is detachably and movably connected to the neutral plate 3011 through the linkage plate 9. Both the neutral plate 3011 and the side plate 3012 are arc-shaped. And a shrinkage plate 10 is rotatably installed on the inner arc surface of the neutral plate 3011. One end of the shrinkage plate 10 is rotatably connected to a guide rod 11. A sliding rod 302 is slidably connected inside the positioning sleeve 303. Multiple groups of avoidance holes are opened in a circle on the outer side of the positioning sleeve 303. One end of the guide rod 11 passes through the inside of the avoidance hole and is fixedly connected to the sliding rod 302; One side of the neutral plate 3011 close to the side plate 3012 is inclined. The linkage plate 9 is composed of an extension plate 901, a receiving plate 902 and a rotating seat 903. The rotating seat 903 is rotatably installed on one side of the neutral plate 3011 close to the side plate 3012. The rotating seat 903 is engaged with one end of the receiving plate 902. A sliding groove is opened at the other end of the receiving plate 902. One end of the extension plate 901 is slidably installed inside the sliding groove. The other end of the extension plate 901 is rotatably connected to the side plate 3012;

[0053] As Figures 1 to 15 shown, through the design that the arc-shaped plate 301 is composed of the neutral plate 3011 and two groups of side plates 3012, the neutral plate 3011 can rely on the inclined characteristics on both sides to approach or move away from the positioning sleeve 303 alone. And after the arc-shaped plate 301 approaches the positioning sleeve 303 by a certain distance, the extension plate 901 can cooperate with the receiving plate 902 to drive the two groups of side plates 3012 to approach each other, thereby changing the circumference of the cylinder formed by the initial multiple groups of arc-shaped plates 301. Therefore, the winding roller 3 after changing the shape can not contact the inside of the wound fabric, making it convenient for the staff to quickly take out the fabric, thus further improving the work efficiency.

[0054] Further, a plurality of guide plates 12 are slidably installed around the outer side of the positioning sleeve 303, and the guide plates 12 are arranged in pairs with the neutral plate 3011. The plurality of guide plates 12 are arranged in an annular and equidistant manner. The guide plates 12 are fixedly connected to the neutral plate 3011. One set of winding mechanisms further includes a plurality of sliders, and the sliders are fixedly installed at one end of the side plate 3012 close to the side mounting plate 7. Thus, the side plate 3012 is slidably connected to the side mounting plate 7 through the sliders;

[0055] As Figures 1 to 15 shown, through the design of the guide plates 12, the neutral plate 3011 can approach the positioning sleeve 303 more stably, improving the stability of the two side plates 3012 approaching each other.

[0056] Further, the side mounting plate 7 is composed of a bearing plate 701 and a rotating plate 702. The bearing plate 701 is fixedly connected to the winding table 1. A servo motor 13 is fixedly installed on one side of the bearing plate 701 away from the winding roller 3. One end of the output shaft of the servo motor 13 penetrates through one side of the bearing plate 701, and one end of the output shaft of the servo motor 13 is fixedly connected to the rotating plate 702; The side plate 3012 is slidably installed on one side of the rotating plate 702 through the slider, and one set of positioning sleeves 303 is rotatably installed on one side of the side plate 3012. The plurality of winding rollers 3 are arranged in an annular and equidistant manner on one side of the rotating plate 702;

[0057] As Figures 1 to 15 shown, through the design of fixedly connecting one end of the output shaft of the servo motor 13 to the rotating plate 702, the plurality of winding rollers 3 can be rotated and replaced, avoiding the need to repeatedly disassemble one winding roller 3, thus saving a large amount of time and further improving work efficiency.

[0058] Specifically, as Figures 1 to 15 shown, a plurality of winding motors 17 are fixedly installed on the other side of the rotating plate 702, and the winding motors 17 are arranged in pairs with the winding rollers 3. One end of the output shaft of the winding motor 17 penetrates through the other side of the rotating plate 702. A plurality of rotating holes are formed in a circle on one side of the rotating plate 702, and a rotating plate 16 is rotatably connected inside the rotating holes. One end of the output shaft of the winding motor 17 is fixedly connected to the rotating plate 16.

[0059] Specifically, as Figures 1 to 15 shown, in one set of winding mechanisms close to the rotating plate 16, the same ends of the side plates 3012 included are fixedly connected to the sliders, and the side plates 3012 are slidably installed on one side of the rotating plate 16 through the sliders.

[0060] As Figures 1 to 15 shown, due to the design of slidably installing the side plates 3012 on one side of the rotating plate 16 through the sliders, when the two side plates 3012 approach each other, they can be more stable through the sliders, thereby improving the stability during the deformation of the winding roller 3.

[0061] It should be noted that due to the fabric characteristics of the meltblown non-woven fabric, it is necessary to deal with the static electricity caused by reducing the friction between the winding roller 3 and the fabric, especially to avoid the accumulation of local static electricity. Otherwise, it may attract dust and impurities or attract the non-woven fabric to produce small wrinkles, which will affect the normal winding of the meltblown non-woven fabric.

[0062] Specifically, as Figures 1 to 15 shown, a copper spring 305 is provided between the neutral plate 3011 and the side plate 3012 included in two adjacent winding mechanisms. The copper spring 305 is provided at one end of the neutral plate 3011 included in one set of winding mechanisms. A docking groove is provided at the other end of the neutral plate 3011, and a conductive head 304 is provided inside the docking groove. A connecting wire 306 is provided between the copper spring 305 and the conductive head 304. Thus, the copper spring 305 and the conductive head 304 are electrically connected through the connecting wire 306, and the neutral plates 3011 and the side plates 3012 included in the two sets of winding mechanisms are detachably arranged with each other through the copper spring 305 and the conductive head 304.

[0063] Specifically, as Figure 15 shown, a ground wire joint terminal 14 is provided outside the winding motor 17, and the ground wire joint terminal 14 is electrically connected to a wire 15. The wire 15 is electrically connected to the copper spring 305 close to the rotating plate 16 to realize power-on.

[0064] Through the design of the copper spring 305 and the conductive head 304 designed above, not only can the two adjacent neutral plates 3011 and the two adjacent side plates 3012 be electrically connected to each other, but also the characteristics of the copper spring 305 can be used to realize mutual clamping and fixing.

[0065] Thus, the effects of modularization and charge circulation on the outer surfaces of the neutral plate 3011 and the side plate 3012 can be realized, so that the charges on the same roller are as equal as possible everywhere, to avoid the accumulation of local static electricity, resulting in the adsorption of too many impurities and affecting its winding quality; it also avoids the interference caused by the adsorption of a large amount of static electricity on a certain side plate 3012 to the fabric, and further reduces the possibility of wrinkles generated during winding.

[0066] For the charges on the overall roller, they are released through the ground wire. The above structure ensures that the charges on any side plate 3012 can be released. The relevant structure of the ground wire has been shown in Figure 15 shown.

[0067] Furthermore, the bending assembly 5 includes a connecting sleeve 502 and a plurality of folding plates 501, the positioning shell 506 is fixedly connected to the connecting sleeve 502, the folding plates 501 are arranged in pairs with the winding roller 3, the connecting sleeve 502 is rotatably installed between the bearing plate 701 and the support column 6, the plurality of folding plates 501 are arranged in an annular shape with equal spacing, and the plurality of folding plates 501 are rotatably connected to the connecting sleeve 502, and the sliding rod 302 is detachably connected to the folding plates 501; the bending assembly 5 also includes a positioning shell 506 and a second tooth plate 507, the second tooth plate 507 is fixedly connected to the bearing plate 701 and the support column 6, and the plurality of folding plates 501 are arranged in an annular shape with equal spacing, and the plurality of folding plates 501 are rotatably connected to the connecting sleeve 502, and the sliding rod 302 is detachably connected to the folding plates 501; Fixedly installed at the upper end of the support column 6, a transmission groove is opened on one side of the positioning shell 506, and a second driven gear 504 is rotatably connected inside the transmission groove. The second driven gear 504 is meshed and connected with the outer side of the second tooth plate 507. One side of the second driven gear 504 is meshed and transmission-connected with a bevel gear transmission mechanism 505, which is arranged inside the transmission groove, and a rotating rod 503 is transmission-connected at the end of the bevel gear transmission mechanism 505. The rotating rod 503 is fixedly connected to the folding plate 501, and the rotating rod 503 is rotationally connected to the connecting sleeve 502;

[0068] like Figures 1 to 15 As shown, through the mutual cooperation of the second driven gear 504, the second tooth plate 507 and the rotating rod 503, when multiple groups of winding rollers 3 are rotated and replaced, after the winding roller 3 on the outer side of the surface winding is rotated and moved to a certain position by the servo motor 13, the second driven gear 504 will engage with the second tooth plate 507, and the second driven gear 504 can control the rotation of the rotating rod 503 through the bevel gear transmission mechanism 505, and the rotating rod 503 drives the folding plate 501 to rotate, thereby controlling the fabric slackening mechanism 4 to move away from the winding roller 3, so as to make room for the staff to pull out the wound fabric.

[0069] Therefore, the work can be carried out automatically through the transmission of the mechanical position, which solves the low work efficiency of the staff manually disassembling the winding roller 3 to take out the fabric.

[0070] Furthermore, the fabric loosening mechanism 4 includes a first tooth plate 401, which is fixedly installed on the upper end of the support column 6, and one end of one side of the folding plate 501 is rotatably connected to the first driven gear 402, and the first driven gear 402 is meshed and connected with the inner side of the first tooth plate 401, and a threaded hole is provided at the center of the first driven gear 402, and a driving threaded rod 404 is threadedly connected inside the threaded hole, and a sliding damping hole is provided at the center of the driving threaded rod 404, and a damping docking rod 403 is slidably inserted inside the sliding damping hole, and two adjacent groups of sliding rods 302 are arranged to be engaged with each other, and an engaging groove is provided at one end of one of the adjacent groups of sliding rods 302, and a multilateral clamping block 8 is fixedly installed at one end of the damping docking rod 403, and the multilateral clamping block 8 is engaged inside the engaging groove;

[0071] like Figures 1 to 15As shown, through the design of the mutual cooperation between the first toothed plate 401 and the first driven gear 402, when multiple groups of winding rollers 3 are rotated and replaced, after the winding roller 3 on the outer side of the surface winding is rotated and moved to a certain position by the servo motor 13, the first driven gear 402 meshes with the first toothed plate 401, the first driven gear 402 rotates, and the driving threaded rod 404 is controlled to move through the threaded hole. The driving threaded rod 404 pulls the sliding rod 302 to slide through the damping docking rod 403, so that the neutral plate 3011 approaches the positioning sleeve 303, and the two side plates 3012 approach each other, thereby realizing the rapid change of the shape of the winding roller 3 and facilitating the staff to take out the fabric quickly.

[0072] It should be noted that through the design of the damping docking rod 403 and the sliding damping hole, when splicing winding rollers 3 of different lengths, the driving threaded rod 404 can be docked with the corresponding sliding rod 302 through the sliding damping docking rod 403.

[0073] It is worth noting that when the driving threaded rod 404 rotates, since the sliding rod 302 is matched with the avoidance hole and the guide rod 11, it can prevent the driving threaded rod 404 from rotating following the threaded hole, resulting in the threaded hole being unable to drive the driving threaded rod 404 to operate normally.
