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; 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 DESCRIPTION

[0025] 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; 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.

[0026] Furthermore, the winding mechanism includes multiple sets of arc plates 301 and positioning sleeves 303, and the multiple sets of arc plates 301 are combined to form a cylinder, the multiple sets of arc plates 301 are mutually engaged, and the multiple sets of arc plates 301 are movably connected to the positioning sleeves 303; like Figures 1 to 15 As shown, a cylindrical design is formed by combining multiple groups of arc plates 301. Multiple groups of arc plates 301 can be combined into a shorter winding roller 3, and the winding mechanism is provided with multiple groups, and can be spliced ​​with each other, so that winding rollers 3 of different lengths can be combined to form, making it convenient for non-woven fabrics of different widths, thereby effectively improving the practicability of the winding equipment.

[0027] Further, the arc plate 301 is composed of a neutral plate 3011 and two sets of side plates 3012, the neutral plate 3011 is located between the two sets of side plates 3012, and a linkage plate 9 is arranged between the neutral plate 3011 and the side plates 3012, so that the side plates 3012 are detachably connected to the neutral plate 3011 through the linkage plate 9, the neutral plate 3011 and the side plates 3012 are both arranged in an arc shape, and a retractable plate 10 is rotatably installed on the inner arc surface of the neutral plate 3011, one end of the retractable plate 10 is rotatably connected to the guide rod 11, the inner locating sleeve 303 is slidably connected to the sliding rod 302, and the locating sleeve 303 is slidably connected to the sliding rod 302. A plurality of avoidance holes are provided around the outer side of the 3, and one end of the guide rod 11 passes through the avoidance hole and is fixedly connected to the sliding rod 302; the side of the neutral plate 3011 close to the side plate 3012 is inclined, and the linkage plate 9 is composed of an extension plate 901, a storage plate 902 and a rotating seat 903, and the rotating seat 903 is rotatably installed on the side of the neutral plate 3011 close to the side plate 3012, and the rotating seat 903 is engaged with one end of the storage plate 902, and a sliding groove is provided at the other end of the storage plate 902, and one end of the extension plate 901 is slidably installed inside the sliding groove, and the other end of the extension plate 901 is rotatably connected to the side plate 3012; like Figures 1 to 15 As shown, through the design that the arc plate 301 is composed of a neutral plate 3011 and two groups of side plates 3012, the neutral plate 3011 can rely on the characteristic of being inclined on both sides to approach or move away from the positioning sleeve 303 alone, and after the arc plate 301 approaches the positioning sleeve 303 for a certain distance, the extension plate 901 can cooperate with the storage plate 902 to drive the two groups of side plates 3012 to approach each other, thereby changing the circumference of the cylinder composed of the initial multiple groups of arc plates 301. Therefore, the winding roller 3 after changing its shape may not contact the inside of the wound fabric, making it convenient for the staff to quickly take out the fabric, thereby further improving work efficiency.

[0028] Further, multiple groups 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, and the multiple groups of guide plates 12 are arranged in a ring with equal distances, and the guide plates 12 are fixedly connected to the neutral plate 3011, and one group of winding mechanisms also includes multiple groups of sliders, and the sliders are fixedly installed at one end of the side plate 3012 close to the side mounting plate 7, so that the side plate 3012 is slidably connected to the side mounting plate 7 through the sliders; like Figures 1 to 15 As shown, through the design of the guide plate 12, the neutral plate 3011 can be more stably close to the positioning sleeve 303, thereby improving the stability of the two sets of side plates 3012 approaching each other.

[0029] 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 platform 1, a servo motor 13 is fixedly installed on the side of the bearing plate 701 away from the winding roller 3, one end of the output shaft of the servo motor 13 passes 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 a slider, and one group of positioning sleeves 303 is rotatably installed on one side of the side plate 3012, and multiple groups of winding rollers 3 are equidistantly arranged in a ring shape on one side of the rotating plate 702; like Figures 1 to 15 As shown, by the design that one end of the output shaft of the servo motor 13 is fixedly connected to the rotating plate 702, multiple groups of winding rollers 3 can be rotated and replaced, avoiding the need to repeatedly disassemble a winding roller 3, thereby saving a lot of time and further improving work efficiency.

[0030] Specifically, Figures 1 to 15 As 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 roller 3. One end of the output shaft of the winding motor 17 passes through the other side of the rotating plate 702. A plurality of rotating holes are opened around 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.

[0031] Specifically, Figures 1 to 15 As shown, the same end of the side plates 3012 included in a group of winding mechanisms close to the rotating plate 16 are fixedly connected to the slider, and the side plates 3012 are slidably installed on one side of the rotating plate 16 through the slider.

[0032] like Figures 1 to 15 As shown, due to the design that the side plate 3012 is slidably installed on one side of the rotating plate 16 through a slider, when the two sets of side plates 3012 are close to each other, they can be more stable through the slider, thereby improving the stability of the winding roller 3 during deformation.

[0033] It is worth noting that due to the fabric characteristics of the meltblown non-woven fabric, it is necessary to deal with and reduce the static electricity caused by the friction between the winding roller 3 and the fabric, especially to avoid the accumulation of local static electricity, otherwise it may attract dust impurities or attract the non-woven fabric to produce tiny wrinkles, thereby affecting the normal winding of the meltblown non-woven fabric.

[0034] Specifically, Figures 1 to 15As shown, a copper spring 305 is arranged between the neutral plate 3011 and the side plate 3012 included in two adjacent groups of winding mechanisms, and the copper spring 305 is arranged at one end of the neutral plate 3011 included in one group of winding mechanisms, and a docking groove is opened at the other end of the neutral plate 3011, and a conductive head 304 is arranged inside the docking groove, and a connecting line 306 is arranged between the copper spring 305 and the conductive head 304, so that the copper spring 305 and the conductive head 304 are electrically connected through the connecting line 306, and the neutral plate 3011 and the side plate 3012 included in the two groups of winding mechanisms are detachably arranged from each other through the copper spring 305 and the conductive head 304.

[0035] Specifically, Fig.15 As shown, a ground terminal 14 is provided on the outside of the winding motor 17, and the ground terminal 14 is electrically connected to a wire 15, and the wire 15 is electrically connected to a copper spring 305 close to the rotating plate 16 to achieve power supply.

[0036] Through the design of the copper spring 305 and the conductive head 304 as described above, not only can the two adjacent groups of neutral plates 3011 and the two adjacent groups of side plates 3012 be electrically connected to each other, but they can also be fixed to each other through the characteristics of the copper spring 305.

[0037] Thereby, modularization is achieved and the outer surfaces of the neutral plate 3011 and the side plate 3012 can be used for charge flow, so that the charge on the same roller is as equal as possible, so as to avoid the accumulation of local static electricity, which leads to the adsorption of too many impurities and affects the winding quality; it also avoids a certain side plate 3012 containing a large amount of static electricity causing adsorption interference to the cloth, further reducing the possibility of wrinkles during winding.

[0038] The charge on the whole roller is released through the grounding wire. The above structure ensures that the charge on any side plate 3012 can be released. The grounding wire related structure has been Fig.15 Shown in.

[0039] 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; 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.

[0040] 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.

[0041] 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; like Figures 1 to 15As shown, through the design of the mutual cooperation between the first tooth 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 engages with the first tooth plate 401, and the first driven gear 402 rotates, and controls the movement of the driving threaded rod 404 through the threaded hole, and the driving threaded rod 404 pulls the sliding rod 302 to slide through the damping docking rod 403, so that the neutral plate 3011 is close to the positioning sleeve 303, and the two groups of side plates 3012 are close to each other, so that the shape of the winding roller 3 can be quickly changed, and the staff can quickly and conveniently take out the fabric.

[0042] It should be noted that, through the design of the damping docking rod 403 and the sliding damping hole, when the winding rollers 3 of different lengths are spliced, the driving threaded rod 404 can be connected to the corresponding sliding rod 302 through the sliding damping docking rod 403.

[0043] It is worth noting that when the driving threaded rod 404 rotates, the sliding rod 302 can prevent the driving threaded rod 404 from rotating with the threaded hole due to the cooperation between the avoidance hole and the guide rod 11, resulting in the threaded hole being unable to drive the driving threaded rod 404 to operate normally.

[0044] The above-mentioned winding equipment for meltblown non-woven fabric production can improve the practicability of the winding equipment and improve the work efficiency through the modularly designed winding roller 3, multiple winding rollers 3 can be replaced with each other, and the fabric loosening mechanism 4 and the bending component 5 cooperate with each other. At the same time, through the structure such as the ground wire connector terminal 14, the non-woven fabric can be better protected to avoid quality damage during the winding process.

It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
