Description

Technical Field

[0001] The utility model belongs to the technical field of meltblown cloth processing, and particularly relates to a winding device for processing low-resistance water electret meltblown cloth. Background Technique

[0002] Low-resistance water electret meltblown cloth, also known as low-resistance hydroentangled electret meltblown cloth, is to cool the meltblown cloth with cold water, and spray and pierce the meltblown cloth with ultrapure water at a certain angle, pressure and flow rate, and generate static electricity by the friction between water and the cloth.

[0003] Meltblown cloth uses polypropylene as the main raw material, and its fiber diameter can reach 1-5 microns. It can be used in fields such as air and liquid filtration materials, isolation materials, absorption materials, mask materials, thermal insulation materials, oil absorption materials and wiping cloths. In the microscopic structure of meltblown cloth, there are many voids, the structure is fluffy, and the anti-wrinkle ability is good. The ultrafine fibers with unique capillary structures can increase the number and surface area of fibers per unit area, so that meltblown cloth has good filtration, shielding, heat insulation and oil absorption properties.

[0004] In the process of realizing the present utility model, the inventor found that there are at least the following problems in this technology: in the process of processing low-resistance water electret meltblown cloth, it is necessary to wind the finished product. The current winding device usually does not have a structure for limiting the position of the meltblown cloth, resulting in the horizontal and vertical positions (height) of the meltblown cloth being misaligned when it is input, and then resulting in one side of the meltblown cloth being loose and the other side being tight when it is wound, causing the meltblown cloth to wrinkle and the quality to decline.

[0005] Therefore, we propose a winding device for processing low-resistance water electret meltblown cloth to solve the above problems. Content of the Utility Model

[0006] The main purpose of the present utility model is to provide a winding device for processing low-resistance water electret meltblown cloth, so that the meltblown cloth always maintains a smooth state when being wound, the probability of generating wrinkles is greatly reduced, and its quality is guaranteed, which can effectively solve the problems in the background technique.

[0007] In order to achieve the above purpose, the present utility model adopts the following technical scheme:

[0008] A winding device for processing low-resistance water electret meltblown cloth, comprising a workbench and a winding mechanism located on the workbench. On one side of the top wall of the workbench, a top support is welded. The winding mechanism includes a winding motor horizontally installed on the top support, an outer edge shaft coaxially connected to the output shaft of the winding motor, and a winding cylinder slidably inserted on the outer edge shaft. The connection mode between the winding cylinder and the outer edge shaft is spline connection, so that when the outer edge shaft rotates, it can drive the winding cylinder to rotate synchronously. On the side of the outer edge shaft facing the top support, a fixed disk for limiting one side of the winding cylinder is welded;

[0009] On the side of the workbench facing away from the top support, a servo motor is horizontally installed. On the other side of the top wall of the workbench, a top groove is formed. The output shaft of the servo motor is coaxially connected with a first screw rod. A sliding seat is threadedly sleeved on the first screw rod, and the sliding seat is attached to the bottom wall of the top groove, so that when the first screw rod rotates, it will drive the sliding seat to slide horizontally along the bottom wall of the top groove. On the sliding seat, a movable disk for limiting the other side of the winding cylinder is welded;

[0010] On the workbench, a column is also welded. A knob is rotatably connected to the column. On the side of the column facing the winding cylinder, a side groove is formed. Below the knob, a second screw rod is coaxially connected. A receiving seat is threadedly sleeved on the second screw rod, and the receiving seat is attached to the inner wall of the side groove, so that when the second screw rod rotates, it can drive the receiving seat to slide vertically along the inner wall of the side groove. A through groove for limiting the meltblown cloth is formed on the receiving seat. By limiting the meltblown cloth through the through groove during input, the purpose is to make the meltblown cloth always maintain a nearly horizontal state when being transported to the winding cylinder and wound, and to correct the position of the meltblown cloth in the horizontal direction by the through groove.

[0011] As a preferred implementation scheme, the winding motor and the outer edge shaft are distributed on both sides of the top support, and the outer edge shaft is rotatably connected to the top support; so that when the winding motor operates, it can drive the outer edge shaft and the winding cylinder on it to operate stably.

[0012] As a preferred implementation scheme, both the fixed disk and the movable disk are vertically arranged and parallel to each other, and the fixed disk and the movable disk have exactly the same structure; before the winding cylinder performs the winding work, by attaching the fixed disk and the movable disk to both sides of the winding cylinder respectively, the meltblown cloth can be prevented from shifting to the outside from the edge of the winding cylinder during winding.

[0013] As a preferred implementation scheme, the first screw rod is horizontally arranged in the top groove, and both sides of the first screw rod are rotatably connected to the workbench; so that the first screw rod can operate stably driven by the servo motor and drive the sliding seat to slide smoothly in the top groove. The winding motor and the servo motor need to be powered separately by external power facilities.

[0014] As a preferred embodiment, the second screw rod is vertically arranged in the side groove, and both sides of the second screw rod are rotatably connected to the column; so that the second screw rod can operate stably driven by the knob.

[0015] As a preferred embodiment, one side of the receiving seat extends out of the side groove and extends horizontally; the part of the receiving seat extending out of the side groove just corresponds to the position of the winding drum, so as to facilitate the through groove to limit the position when the meltblown cloth is input.

[0016] As a preferred embodiment, the position of the through groove corresponds to the lowermost position of the outer wall of the winding drum; so that the meltblown cloth can be input from the lowermost position of the outer wall of the winding drum and wound thereon.

[0017] In summary, the technical effects and advantages of the present utility model are as follows:

[0018] For the winding device for processing low-resistance water-electret meltblown cloth, by rotating the knob to drive the second screw rod to operate, the receiving seat is lifted or lowered accordingly, and the height can be adjusted according to the different thicknesses of the meltblown cloth on the winding drum, so that the meltblown cloth input at the receiving seat is always in a nearly horizontal state, so that the meltblown cloth always remains smooth during winding, and the probability of generating wrinkles is greatly reduced, ensuring its quality;

[0019] For the winding device for processing low-resistance water-electret meltblown cloth, through the through groove on the receiving seat, not only the height of the meltblown cloth can be limited, but also the horizontal position when the meltblown cloth is input can be limited, so as to avoid the horizontal misalignment of the meltblown cloth, and further avoid the quality degradation problem caused by the stretching or shrinking of the meltblown cloth.

Detailed Embodiments

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Referring to Figures 1-4 , a winding device for processing low-resistance water electret meltblown cloth, including a workbench 1 and a winding mechanism located on the workbench 1. On one side of the top wall of the workbench 1, a top support 2 is welded. The winding mechanism includes a winding motor 3 horizontally installed on the top support 2, an outer edge shaft 4 coaxially connected to the output shaft of the winding motor 3, and a winding cylinder 6 slidably inserted on the outer edge shaft 4. The winding motor 3 and the outer edge shaft 4 are distributed on both sides of the top support 2, and the outer edge shaft 4 is rotatably connected to the top support 2, so that when the winding motor 3 operates, it can drive the outer edge shaft 4 and the winding cylinder 6 thereon to rotate stably. The connection mode between the winding cylinder 6 and the outer edge shaft 4 is a spline connection, so that when the outer edge shaft 4 rotates, it can drive the winding cylinder 6 to rotate synchronously. On the side of the outer edge shaft 4 facing the top support 2, a fixed disk 5 for limiting one side of the winding cylinder 6 is welded;

[0027] A servo motor 7 is horizontally installed on the side of the workbench 1 facing away from the top support 2. On the other side of the top wall of the workbench 1, a top groove 8 is formed. The output shaft of the servo motor 7 is coaxially connected to a first screw rod 9. A sliding seat 10 is threadedly sleeved and installed on the first screw rod 9. The first screw rod 9 is horizontally arranged in the top groove 8, and both sides of the first screw rod 9 are rotatably connected to the workbench 1, so that the first screw rod 9 can rotate stably under the drive of the servo motor 7 and drive the sliding seat 10 to slide smoothly in the top groove 8. The winding motor 3 and the servo motor 7 need to be independently powered by external power facilities, and the sliding seat 10 is in contact with the bottom wall of the top groove 8, so that when the first screw rod 9 rotates, it will drive the sliding seat 10 to slide horizontally along the bottom wall of the top groove 8. On the sliding seat 10, a movable disk 11 for limiting the other side of the winding cylinder 6 is welded. The fixed disk 5 and the movable disk 11 are both vertically arranged and parallel to each other, and the fixed disk 5 and the movable disk 11 have exactly the same structure. Before the winding cylinder 6 performs the winding work, the fixed disk 5 and the movable disk 11 are respectively attached to both sides of the winding cylinder 6, so that the meltblown cloth will not shift to the outside from the edge of the winding cylinder 6 during winding;

[0028] A column 12 is also welded on the workbench 1. A knob 13 is rotatably connected to the column 12. A side groove 14 is formed on one side of the column 12 facing the winding drum 6. A second screw rod 15 is coaxially connected below the knob 13. The second screw rod 15 is vertically arranged in the side groove 14, and both sides of the second screw rod 15 are rotatably connected to the column 12, so that the second screw rod 15 can operate stably under the drive of the knob 13. A receiving seat 16 is threadedly sleeved on the second screw rod 15. The receiving seat 16 is attached to the inner wall of the side groove 14, so that the second screw rod 15 can drive the receiving seat 16 to slide vertically along the inner wall of the side groove 14 during operation. One side of the receiving seat 16 extends out of the side groove 14 and extends horizontally;

[0029] The part of the receiving seat 16 extending out of the side groove 14 just corresponds to the position of the winding drum 6, so as to facilitate the position limiting of the meltblown cloth when it is input through the through groove 17. The position of the through groove 17 corresponds to the lowermost position on the outer wall of the winding drum 6, so that the meltblown cloth can be input from the lowermost position on the outer wall of the winding drum 6 and wound thereon. A through groove 17 for limiting the meltblown cloth is formed on the receiving seat 16. The through groove 17 is used to limit the meltblown cloth when it is input, aiming to keep the meltblown cloth in a nearly horizontal state all the time when it is conveyed to the winding drum 6 and wound, and to correct the position of the meltblown cloth in the horizontal direction by the through groove 17.

[0030] For the winding device for processing low-resistance water-electret meltblown cloth: during use, first, the movable disk 11 is located at the position farthest from the fixed disk 5. The winding drum 6 is horizontally slidably inserted on the outer edge shaft 4, so that the outer edge shaft 4 is in spline fit with the winding drum 6. Subsequently, the servo motor 7 is driven to operate to drive the first screw rod 9 to rotate, so that the sliding seat 10 slides horizontally in the top groove 8 and drives the movable disk 11 to pass through the outer edge shaft 4 and fit with the winding drum 6. Using the fixed disk 5 and the movable disk 11 to limit the winding drum 6 can ensure the accuracy of the position during the subsequent winding of the meltblown cloth;

[0031] Fix the head end of the meltblown cloth on the winding drum 6, and then drive the winding motor 3 to operate to drive the outer edge shaft 4, the fixed disk 5 and the winding drum 6 to rotate, so that the meltblown cloth can be continuously wound. During the winding process, the meltblown cloth needs to pass through the through groove 17 when it is input from the outside. Because the through groove 17 corrects the position of the meltblown cloth in the horizontal direction, as the meltblown cloth is continuously wound on the winding drum 6 and the thickness becomes larger and larger, it is necessary to continuously move the through groove 17 downward to ensure that the meltblown cloth is always in a nearly horizontal state when it is input. The specific operation is: rotate the knob 13 to drive the second screw rod 15 to rotate, so that the receiving seat 16 translates along the inner wall of the side groove 14, and then the through groove 17 moves downward.

[0032] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
