Description

Technical Field

[0001] The invention relates to the technical field of electrostatic coating of spunlace nonwoven fabrics, and in particular to an electrostatic coating device for degradable, moisturizing and skin-care spunlace nonwoven fabrics. Background Art

[0002] Spunlace non-woven fabric is a fabric made by spraying high-pressure fine water flow onto one or more layers of fiber webs, causing the fibers to entangle with each other, thereby reinforcing the fiber web and achieving a certain strength. Spunlace non-woven fabric has the characteristics of soft feel, good drape, good moisture absorption, good breathability, smooth appearance and linting. Its application range continues to expand, making it one of the fastest growing varieties of non-woven fabrics. In 2021, the output of spunlace non-woven fabrics accounted for 11.2% of the total output of non-woven fabrics, ranking third in China. In 2022, the output of spunlace non-woven fabrics exceeded 1.4 million tons. At present, the main applications of spunlace non-woven fabrics include civilian cleaning materials such as facial masks, wet wipes, wipes, etc., as well as medical and health materials such as disposable medical sheets, medical dressings, disinfectant wipes, alcohol pads, etc.

[0003] Most of the existing facial mask substrates are non-woven fabrics made of polyester fibers, which have problems such as insufficient skin adhesion and difficulty in degradation after disposal. In addition, most facial masks are adsorbed with essence. In order to prevent the growth of microorganisms, chemical antibacterial agents such as preservatives must be added, which can easily irritate the skin and even affect health; the essence is easy to drip during use, causing inconvenience in use and waste of effective skin care ingredients. To solve the above problems, researchers at home and abroad use electrospinning to mix active ingredients such as skin care and antibacterial with electrospinning liquid and then spin them directly. Researchers from Zhongyuan University of Technology combined hyaluronic acid with gelatin to prepare a biocompatible solid absorbable nanofiber mask without adding preservatives and with high moisturizing properties and strong antioxidant capacity. The team from Dongguk University in South Korea mixed zinc oxide nanoparticles with PVA and PVP to achieve the antibacterial properties of the mask without adding preservatives. However, the electrospinning technology process is complicated, making it difficult to achieve industrial large-scale production, and it cannot ensure that the skin care ingredients are in full contact with the skin, which weakens the functionality of the mask.

[0004] Methods for combining active skin care ingredients with spunlace nonwoven fabrics include online spraying, rotary spraying, gravure roller coating and high-precision spraying. The online spraying method is not prone to polluting the environment, but it will lead to uneven coating, the generation of mist and waste of active ingredients, and its viscosity is also limited to a certain range; the rotary spraying method has a stable coating process and is not prone to interlayer peeling, but the possibility of bubbles must be considered; the gravure roller coating technology can make every part of the fabric receive uniform coating, which is independent of the physical state of the coating, but the equipment is relatively expensive. Therefore, an electrostatic coating device for degradable moisturizing skin care spunlace nonwoven fabric is proposed. Summary of the invention

[0056] Specifically, the speed regulating mechanism 7 also includes a first threaded sleeve 708 threadedly connected to the outer surface of the first screw rod 701, a sliding seat 709 is fixedly connected to the outer surface of the first threaded sleeve 708, the upper surface of the sliding seat 709 is fixedly connected to the support frame 501, and a slide groove 715 for the sliding seat 709 to move is provided on the upper surface of the base 1. A telescopic support rod 710 is fixedly connected to the upper surface of the fixed seat 705, and a compression spring 711 is sleeved on the outer surface of the telescopic support rod 710. A connecting seat 712 is fixedly connected to the top of the telescopic support rod 710, and the connecting seat 712 is fixedly connected to the servo motor 706. The elastic force of the compression spring 711 can always keep the active friction wheel 707 and the driven friction wheel 702 meshing at all times. In the closed state, a limit rod is inserted into the fixed seat 705, and the second screw rod 703 inserted into the fixed seat 705 and the first screw rod 701 inserted into the base 1 are both movably connected to the base 1 through the bearing seat.

[0057] Furthermore, by utilizing the driven friction wheel 702 and the active friction wheel 707, by rotating the second screw rod 703, since the second screw rod 703 is connected to the fixed seat 705 through the second threaded sleeve 704, and the fixed seat 705 is connected to the servo motor 706 through the telescopic support rod 710 and the compression spring 711, when the second screw rod 703 is rotated, the relative position of the driven friction wheel 702 and the active friction wheel 707 can be changed, the transmission ratio of the driven friction wheel 702 and the active friction wheel 707 can be changed, and the moving speed of the support frame 501 can be changed, so that the moving speed of the electrostatic coating mechanism 3 can be changed according to actual needs.

[0058] Working principle: when it is necessary to coat the degradable moisturizing skin-care spunlace nonwoven fabric, the degradable moisturizing skin-care spunlace nonwoven fabric is placed on the upper surface of the coating platform 2, and then the spunlace nonwoven fabric is fixed by the fixed pressing plate on the coating platform 2, and then the electrostatic coating mechanism 3 is used to coat it. The working principle and connection method of the fixed pressing plate and the electrostatic coating mechanism are common knowledge known to technicians in this field, and will not be described in detail here.

The threaded rod 503 is movably connected to the mounting seat 504 through the bearing seat, so when the threaded rod 503 is rotated, the mounting seat 504 can be driven to move up and down, so as to adjust the distance between the electrostatic coating mechanism 3 and the material, and when the spunlace non-woven fabric is coated, the spunlace non-woven fabric can be smoothed to both sides by the smoothing plate 604 when the electrostatic coating mechanism 3 moves. Since the smoothing plate 604 is located at the front side of the electrostatic coating mechanism 3, when the electrostatic coating mechanism 3 moves, the smoothing plate 604 and the pressing roller 603 can be used under the action of the spring 606. The spunlace nonwoven fabric can be smoothed before coating to prevent wrinkles and uneven coating. The driven friction wheel 702 and the active friction wheel 707 are used to rotate the second screw rod 703. Since the second screw rod 703 is connected to the fixed seat 705 through the second threaded sleeve 704, and the fixed seat 705 is connected to the servo motor 706 through the telescopic support rod 710 and the compression spring 711, when the second screw rod 703 is rotated, the relative position of the driven friction wheel 702 and the active friction wheel 707 can be changed. 07 are all conical, so when the relative positions of the driven friction wheel 702 and the active friction wheel 707 change, the transmission ratio of the driven friction wheel 702 and the active friction wheel 707 can be changed. At the same time, since the driven friction wheel 702 is connected to the first screw rod 701, and the first screw rod 701 is connected to the support frame 501 through the first threaded sleeve 708 and the sliding seat 709, when the transmission ratio of the driven friction wheel 702 and the active friction wheel 707 is changed, the moving speed of the support frame 501 can be changed, so that the moving speed of the electrostatic coating mechanism 3 can be changed according to actual needs.
