Description

Technical Field

[0001] This utility model belongs to the technical field of nonwoven fabric processing equipment, specifically a coating device for reducing lint shedding in nonwoven fabrics. Background Technology

[0002] Nonwoven fabrics, widely used in hygiene products, packaging materials, and filter materials, have long faced significant challenges due to lint shedding. During production, processing, and use, the weak bond between fibers in nonwoven fabrics easily leads to fiber shedding. These shed fibers not only affect the product's appearance but can also pollute the environment. For example, in the hygiene products sector, lint may pose a potential threat to human health; in the filter materials sector, lint reduces filtration efficiency and affects filtration effectiveness.

[0003] Currently, to reduce lint shedding in nonwoven fabrics, an adhesive is typically applied to the fabric surface. However, existing coating devices have several shortcomings. For example, poor coating uniformity leads to insufficient adhesive application in some areas, failing to effectively fix the fibers and still resulting in lint shedding. The coating equipment is also ill-suited for nonwoven fabrics of varying thicknesses, making it difficult to precisely control the coating amount and effect for both thicker and thinner fabrics. Furthermore, adhesive sedimentation and delamination are common during the coating process, affecting adhesive performance and overall coating quality. Therefore, there is an urgent need for a coating device that can improve coating uniformity, adjust coating parameters to suit different nonwoven fabric requirements, and ensure stable adhesive quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a coating device that reduces lint shedding in nonwoven fabrics. This device solves the technical problems of poor coating uniformity, resulting in insufficient adhesive coating in some areas and inability to effectively fix the fibers; and the difficulty of adapting coating equipment to nonwoven fabrics of different thicknesses, making it impossible to accurately control the coating amount and coating effect for thicker or thinner nonwoven fabrics.

[0005] The present invention adopts the following solution: a coating device for reducing lint shedding in non-woven fabrics, characterized in that it comprises:

[0006] The machine body has an adhesive tank connected to the bottom and a coating pipe connected to the top. Several coating nozzles are connected to the bottom of the coating pipe. An auxiliary pipe is connected between the coating pipe and the adhesive tank, and a pump body is installed on the auxiliary pipe.

[0007] The coating wheel is rotatably connected to the inner wall of the machine body.

[0008] The distance adjustment assembly includes a conveyor wheel, a coating wheel, and the conveyor wheel being driven by a power assembly. The distance adjustment assembly is used to adjust the distance between the conveyor wheel and the coating wheel.

[0009] The coating hopper is rotatably connected to the inner wall of the machine body. An angle adjustment component is provided on the machine body to adjust the angle of the coating hopper. The bottom of the coating hopper is provided with a coating port corresponding to the coating wheel.

[0010] Preferably, the distance adjustment component includes:

[0011] Two sliding grooves are opened on the side wall of the machine body. An auxiliary plate is slidably connected in each of the two sliding grooves. A conveyor wheel is rotatably connected between the auxiliary plates. A height telescopic rod is provided in each of the two sliding grooves. The extended end of the height telescopic rod is connected to the auxiliary plate.

[0012] Preferably, the angle adjustment component includes an angle telescopic rod hinged between the machine body and the coating hopper.

[0013] Preferably, the power assembly includes two sets of electric motors, which drive the coating wheel and the conveying wheel respectively.

[0014] Preferably, the coating nozzle is a fan-shaped nozzle.

[0015] Preferably, the adhesive tank is equipped with a stirring device, which includes a stirring shaft and stirring blades, and the stirring shaft is driven by a stirring motor.

[0016] Beneficial effects:

[0017] 1. Improved Coating Uniformity: This application incorporates a coating pipeline and several fan-shaped coating nozzles. The adhesive is pumped from the adhesive tank to the coating pipeline, where it is then evenly sprayed onto the nonwoven fabric surface by the fan-shaped nozzles. The spray angle of the fan-shaped nozzles can cover a certain width, resulting in a more uniform distribution of the adhesive. Compared to traditional nozzles, this significantly improves coating uniformity, thereby more effectively fixing the nonwoven fabric fibers and reducing lint shedding.

[0018] The coating wheel works in conjunction with the coating hopper, with the coating port at the bottom of the coating hopper corresponding to the coating wheel. The angle of the coating hopper can be adjusted by the angle adjustment component, which can adjust the angle and flow rate of the adhesive to the coating wheel according to different coating requirements, further ensuring the uniformity of coating.

[0019] II. Adaptability to Nonwoven Fabrics of Different Thicknesses: The distance adjustment component allows for adjustment of the distance between the conveyor wheel and the coating wheel. The height of the conveyor wheel is changed by sliding the auxiliary plate within the sliding groove via a height telescopic rod. When processing nonwoven fabrics of varying thicknesses, the distance between the conveyor wheel and the coating wheel can be flexibly adjusted to ensure appropriate tension and coating pressure during conveying and coating, improving coating effectiveness and effectively reducing uneven coating and lint problems caused by differences in nonwoven fabric thickness.

[0020] III. Ensuring Stable Adhesive Quality: A stirring device is installed inside the adhesive tank. The stirring motor drives the stirring shaft and blades to continuously stir the adhesive. This prevents sedimentation and stratification of the adhesive during storage and use, ensuring its uniformity and stability. This allows the adhesive coated on the nonwoven fabric to exhibit excellent performance, better fulfilling its function of fixing fibers and reducing lint.

[0021] IV. Flexible and Efficient Power Drive: The power unit uses two sets of electric motors to drive the coating wheel and the conveyor wheel separately, allowing independent control of their rotation speeds. Depending on the nonwoven fabric material and coating process requirements, the rotation speeds of the coating wheel and conveyor wheel can be flexibly adjusted, achieving precise control of the coating process, improving coating efficiency and quality, and further reducing the possibility of nonwoven fabric shedding.

[0028] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1-5 The detailed description of the embodiments will clearly demonstrate this. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0029] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0030] Example 1: A coating device for reducing lint shedding in nonwoven fabrics. This device is mainly used to uniformly coat the surface of nonwoven fabrics with an adhesive to enhance the bonding force between the nonwoven fibers, thereby reducing lint shedding. The device mainly consists of a body 1, an adhesive supply system, a coating wheel 7, a distance adjustment component, a coating hopper 9, and a power component.

[0031] Main Body 1: Main Body 1 is the supporting structure of the entire device. It is made of high-strength carbon steel and has been treated with rust prevention to ensure its durability and stability. It is rectangular in shape and has enough internal space to accommodate other components.

[0032] Adhesive Tank 2: Adhesive Tank 2 is located at the bottom of Machine Body 1 and is securely connected to Machine Body 1 by welding. The tank is made of stainless steel and can store enough adhesive to meet production needs for a certain period of time. A liquid level sensor is installed inside the tank to monitor the adhesive level in real time, and an alarm signal will be issued when the liquid level is too low.

[0033] Coating pipe 3: Coating pipe 3 is connected to the top of the machine body 1 and is made of PVC pipe with good corrosion resistance. Eight fan-shaped coating nozzles 4 are connected at equal intervals at the bottom of the pipe. The spray angle of the fan-shaped nozzles is 60°, which can make the adhesive evenly sprayed on the surface of the non-woven fabric.

[0034] Auxiliary pipe 5 and pump body 6: Auxiliary pipe 5 connects coating pipe 3 and adhesive tank 2. It is made of rubber hose, which has a certain degree of flexibility and is easy to install and maintain. It can stably deliver adhesive from adhesive tank 2 to coating pipe 3.

[0035] The coating wheel 7 is rotatably connected to the inner wall of the machine body 1 via bearings. The wheel body is made of carbon steel with a chrome-plated surface and is adapted to the width of common non-woven fabrics. The surface of the coating wheel 7 is smooth, which can evenly coat the adhesive onto the non-woven fabric.

[0036] Distance adjustment component

[0037] Sliding groove 11 and auxiliary plate 12

[0038] Two sliding grooves 11 are symmetrically formed on the side wall of the body 1. The sliding grooves 11 are rectangular grooves. The auxiliary plate 12 is made of steel plate, and its two ends are slidably connected to the two sliding grooves 11 respectively. The auxiliary plate 12 can slide smoothly in the sliding grooves 11.

[0039] The conveyor wheel 8 and the height telescopic rod 13 are rotatably connected to the auxiliary plate 12 via bearings. The conveyor wheel 8 is covered with a rubber layer to increase the friction between it and the nonwoven fabric. The height telescopic rod 13 is an electric telescopic rod, and its extended end is fixedly connected to the auxiliary plate 12 by bolts. By controlling the extension and retraction of the height telescopic rod 13, the distance between the conveyor wheel 8 and the coating wheel 7 can be precisely adjusted to accommodate nonwoven fabrics of different thicknesses.

[0040] Coating hopper 9: The coating hopper 9 is rotatably connected to the inner wall of the machine body 1. It is made of stainless steel and has a volume of 50 liters. The bottom of the coating hopper 9 is provided with a coating port 10 corresponding to the coating wheel 7. The coating port 10 is long and narrow, which can evenly flow the adhesive onto the coating wheel 7.

[0041] Angle telescopic rod 14: The angle adjustment assembly includes an angle telescopic rod 14, which is a hydraulic telescopic rod. The two ends of the angle telescopic rod 14 are respectively hinged to the machine body 1 and the coating hopper 9 through ball joints. By controlling the extension and retraction of the angle telescopic rod 14, the angle of the coating hopper 9 can be flexibly adjusted, thereby adjusting the flow rate and angle of the adhesive to the coating wheel 7.

[0042] The power unit includes two sets of electric motors 15, namely the coating wheel 7 electric motor 15 and the conveyor wheel 8 electric motor 15.

[0043] The adhesive tank 2 is equipped with a stirring device, which includes a stirring shaft and stirring blades. The stirring shaft is driven by a stirring motor. The stirring blades are propeller-type, with a total of 3 blades, evenly distributed on the stirring shaft, which can fully stir the adhesive, prevent the adhesive from settling and separating, and ensure the uniformity of the adhesive.

[0044] Workflow

[0045] I. Preparation Stage

[0046] Check that all components of the equipment are securely installed and that all connections are properly sealed.

[0047] Add an appropriate amount of adhesive to adhesive tank 2 and start the stirring motor to stir the adhesive and ensure that the adhesive is mixed evenly.

[0048] Based on the thickness of the nonwoven fabric to be coated, the height telescopic rod 13 is activated by operating the control button to adjust the distance between the conveyor wheel 8 and the coating wheel 7 so that the distance is slightly greater than the thickness of the nonwoven fabric, ensuring that the nonwoven fabric can pass through smoothly and maintain appropriate tension.

[0049] According to the coating process requirements, by operating the control button, the angle telescopic rod 14 is activated to adjust the angle of the coating bucket 9 so that the angle and position between the coating port 10 at the bottom of the coating bucket 9 and the coating wheel 7 reach the optimal coating state.

[0050] II. Coating Stage

[0051] One end of the nonwoven fabric to be coated is introduced between the conveyor wheel 8 and the coating wheel 7. Two sets of motors 15 are started. The motors 15 drive the coating wheel 7 and the conveyor wheel 8 to rotate through the reducer. The conveyor wheel 8 smoothly conveys the nonwoven fabric to the coating area.

[0052] The pump body 6 is started, and the pump body 6 delivers the adhesive in the adhesive tank 2 to the coating pipe 3 through the auxiliary pipe 5. Then, the adhesive is evenly sprayed onto the surface of the nonwoven fabric by the fan-shaped nozzle at the bottom of the coating pipe 3. At the same time, the adhesive also flows into the coating hopper 9 and flows to the coating wheel 7 through the coating port 10 at the bottom of the coating hopper 9. The coating wheel 7 evenly coats the adhesive onto the surface of the nonwoven fabric during rotation, further ensuring the uniformity of the coating.

[0053] During the coating process, the operator can observe the coating status in real time through the observation window. If uneven coating or other abnormalities are found, the relevant parameters can be adjusted in time, such as the flow rate of pump body 6, the rotation speed of coating wheel 7 and conveying wheel 8, and the angle of coating bucket 9.

[0054] III. Follow-up Processing Stage

[0055] After coating, the nonwoven fabric is output from the other side of machine body 1 and enters subsequent drying, curing and other processing steps.

[0056] After a batch of nonwoven fabric coating is completed, turn off pump 6, stirring motor, and two sets of motors 15. Clean the equipment, drain the remaining adhesive from adhesive tank 2, and clean components such as coating pipe 3, coating nozzle 4, coating hopper 9, and coating wheel 7 to prevent adhesive residue from affecting the next use.

[0057] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
