Description

Technical Field

[0001] This utility model relates to the field of coating equipment, and in particular to a uniform coating device for high-elasticity and corrosion-resistant polyester industrial yarn. Background Technology

[0002] High-elasticity and corrosion-resistant polyester industrial yarn is a commonly used material in the industrial field, and is widely used in filter media, conveyor belts, tarpaulins and other scenarios. Its surface coating treatment is crucial to improving its performance. In order to meet the durability requirements of industrial yarn in complex environments, it is necessary to use special equipment to achieve uniform coating.

[0003] The existing high-elasticity and corrosion-resistant polyester industrial yarn uniform coating device first introduces the high-elasticity and corrosion-resistant polyester industrial yarn to be processed into the device's yarn guiding mechanism for positioning and combing according to a set path. Then, the device's coating supply system is started, so that the coating material is delivered to the coating component at a preset rate. Then, the industrial yarn passes through the coating component at a uniform speed under the drive of the traction mechanism, and the surface coating is uniformly adhered. The whole process can be continuously operated in accordance with the rhythm of the production line and is suitable for the batch processing needs of industrial yarn.

[0004] Existing uniform coating devices for high-elasticity, corrosion-resistant polyester industrial yarns have significant drawbacks. Most employ spraying, which results in a large amount of coating material failing to adhere precisely to the yarn surface, leading to substantial waste. Furthermore, polyester yarns contain numerous tiny gaps, making it difficult for conventional spraying methods to penetrate and cover these gaps, resulting in incomplete coating. Immersion methods, on the other hand, cannot effectively eliminate air bubbles trapped within the yarn, which damage the internal structure and significantly reduce yarn strength. Additionally, the devices cannot adjust to different sizes of polyester industrial yarns. When processing yarns of varying diameters and cross-sectional shapes, the lack of adaptability leads to differences in surface tension across the yarn. These tension variations cause significant differences in coating thickness and adhesion, resulting in coating inconsistencies that severely impact coating accuracy and consistency. Therefore, this paper proposes a uniform coating device for high-elasticity, corrosion-resistant polyester industrial yarns to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a uniform coating device for high-elasticity and corrosion-resistant polyester industrial yarn, which aims to improve the problems of waste of coating materials, incomplete coating, reduced yarn strength and poor coating accuracy and consistency in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a device for uniformly coating high-elasticity and corrosion-resistant polyester industrial yarn, comprising a device housing, an electric motor fixedly connected to the top outer wall of the device housing, a rotating shaft fixedly connected to the output end of the electric motor, a polyester yarn bobbin disposed on the outer wall of the rotating shaft of the electric motor, an ultrasonic transmitter disposed on the inner wall of the polyester yarn bobbin, a transmission wheel fixedly connected to the outer wall of the rotating shaft of the electric motor, a transmission belt drivingly connected to the outer wall of the transmission wheel, the transmission belt also drivingly connected to the rotating shaft of a first auxiliary wheel through the transmission wheel, a support plate fixedly connected to the top outer wall of the device housing, a support rod fixedly connected to the outer wall of the device housing, bolt holes opened on the outer wall of the support rod, a buckle connected to the outer wall of the support rod by bolts, and a second auxiliary wheel rotatably connected to the inner wall of the buckle through the rotating shaft.

[0012] As a further description of the above technical solution: The support frame is located directly below the heating coil, and the top outer wall of the support frame has a groove that penetrates its own inner wall.

On the other hand, it can accelerate the drying of the coating, improve the processing efficiency, and further ensure the stability of the coating quality. Attached Figure Description

The transmission belt 11 is also connected to the shaft of the first auxiliary wheel 8 through the transmission wheel 10. A support plate 7 is fixedly connected to the top outer wall of the device housing 1. The support plate 7 is used to support and fix the shaft of the first auxiliary wheel 8. The first auxiliary wheel 8 is rotatably connected to the inner wall of the support plate 7 through the shaft. The first auxiliary wheel 8 can guide and initially tension the polyester filament.

[0020] Reference Figures 2-4 A support rod 2 is fixedly connected to the outer wall of the device housing 1. The support rod 2 is used to install and fix components such as the buckle 17 and the connecting rod 14. A guide rail 15 is fixedly connected to the outer wall of the device housing 1. The guide rail 15 is set in an inclined shape and is located directly below the polyester yarn tube 5. The function of the guide rail 15 is to guide and collect the coating liquid dripping from the polyester yarn tube 5 for easy reuse. The outer wall of the support rod 2 has bolt holes 18, which facilitate the adjustment of the installation height of the buckle 17 by bolts. The outer wall of the support rod 2 is connected to the buckle 17 by bolts. The buckle 17 is used to fix the rotating shaft of the second auxiliary wheel 9. The inner wall of the buckle 17 is rotatably connected to the second auxiliary wheel 9 by the rotating shaft. The second auxiliary wheel 9 can cooperate with the first auxiliary wheel 8 to further adjust the tension of the polyester yarn to ensure consistent yarn stress. Reference Figures 1-3A connecting rod 14 is fixedly connected to the outer wall of the support rod 2. The connecting rod 14 is used to connect the support rod 2 and the mounting base 12 to realize the fixed installation of the heating coil 13. The mounting base 12 is fixedly connected to the outer wall of the connecting rod 14. The mounting base 12 provides a mounting carrier for the heating coil 13. The heating coil 13 is fixedly connected to the outer wall of the mounting base 12. The heating coil 13 is set in a spiral shape. The spiral structure can increase the contact area with the polyester filament and improve the drying efficiency. The heating coil 13 can dry the coated polyester filament and prevent the elastic rebound of the filament from creating gaps. A support frame 16 is fixedly connected to the outer wall of the support rod 2. The support frame 16 is used to support the third auxiliary wheel 19, and the groove on its top can limit the polyester filament. The support frame 16 is located directly below the heating coil 13.

[0021] Working principle: First, the submerged polyester filament bobbin 5 is installed on the rotating shaft driven by the motor 3. Then, the ultrasonic transmitter 6 is installed. Subsequently, the motor 3 on the top of the device housing 1 is started. The rotating shaft of the motor 3 is stabilized by the connecting ring 4 to prevent shaking. At the same time, it drives the polyester filament bobbin 5 fixed on the outer wall to rotate synchronously with the transmission wheel 10. The transmission wheel 10 transmits power to the rotating shaft of the first auxiliary wheel 8 through the transmission belt 11, so that the first auxiliary wheel 8 rotates synchronously with the motor 3 under the support of the support plate 7. Then, the polyester filament is passed through the polyester filament bobbin 5, the first auxiliary wheel 8, the heating coil 13, and the third auxiliary wheel 19 in sequence. Under the guidance and initial tension of the first auxiliary wheel 8, the polyester filament enters the polyester filament bobbin 5. At the same time, the ultrasonic transmitter 6 on the inner wall generates ultrasonic waves to eliminate the polyester filament. Air bubbles are trapped inside the yarn, and coating liquid dripping from the polyester yarn bobbin 5 is guided and collected by the inclined guide rail 15 below for subsequent reuse. Then, according to the size of the polyester yarn, the height of the buckle 17 is adjusted through the bolt hole 18 on the outer wall of the support rod 2, so that the second auxiliary wheel 9 cooperates with the first auxiliary wheel 8 to further adjust the tension of the polyester yarn, ensuring that the yarn stress is consistent. The coated polyester yarn continues to be conveyed to the spiral heating coil 13. Under the fixed support of the mounting base 12 and the connecting rod 14, the heating coil 13 increases the contact area with the polyester yarn and quickly dries the coating, preventing the yarn from elastically rebounding and creating gaps. Finally, the dried polyester yarn passes through the groove at the top of the support frame 16 and is stably conveyed under the guidance of the third auxiliary wheel 19, completing the entire coating process.
