Description

Technical Field

[0001] The utility model relates to the technical field of fiber processing equipment, in particular to an ultra-high molecular weight polyethylene fiber coating device. Background Art

[0002] Ultra-high molecular weight polyethylene fiber, also known as high-strength high-modulus polyethylene fiber, is the fiber with the highest specific strength and specific modulus in the world. It is a fiber spun from polyethylene with a molecular weight of 1 million to 5 million. During the production and processing of ultra-high molecular weight polyethylene fiber, in order to improve the performance, the ultra-high molecular weight polyethylene fiber is generally coated. For example, a Chinese patent with announcement number CN219824597U discloses an ultra-high molecular weight polyethylene fiber coating device, which is coated by soaking and drying. However, soaking requires pouring a large amount of coating solution into the container. After the coating is completed, a large amount of coating solution will still remain in the container, which will cause a waste of resources. In addition, the ultra-high molecular weight polyethylene fiber is not protected during the drawing process, so it is easy to get stuck at the joint point and entangled, resulting in increased costs.

[0003] The existing ultra-high molecular weight polyethylene fiber coating device directly sprays when passing through a box without processing the ultra-high molecular weight polyethylene fiber. Due to its extremely high surface crystallinity, its surface structure is relatively smooth. When in contact with the coating, some of the coating is still difficult to combine with the ultra-high molecular weight polyethylene fiber, resulting in a poor coating effect on the ultra-high molecular weight polyethylene fiber product, which needs to be improved.

[0040] In order to better explain the utility model and facilitate understanding, the utility model is described in detail below with reference to the accompanying drawings and through specific implementation methods. Figure 1 The orientation is used as a reference.

[0041] The ultra-high molecular weight polyethylene coating device proposed in the embodiment of the utility model is improved with respect to the limitations of the prior art. Compared with the Chinese patent name "Ultra-high molecular weight polyethylene fiber coating device" with the announcement number CN219824597U, the device of the utility model adopts the method of ultrasonic atomization spraying and sets two independently adjustable wire separation frames in the coating process, which abandons the traditional soaking, easy jamming of joint points, entanglement and other problems. This innovative design solves the problem of waste of resources during the soaking process and avoids the situation where a large amount of coating solution remains in the container after the coating is completed. At the same time, through the mutual cooperation of the wire separation frames, the wire is prevented from getting stuck at the joint point, and the ultra-high molecular weight polyethylene fiber is protected during the wire drawing process to prevent entanglement and intertwining, which greatly saves costs.

[0042] The existing technology still has the problem that "the surface crystallinity of ultra-high molecular weight polyethylene fibers is high, which makes it difficult for coatings to combine with them". This device adopts a unique processing method, specifically an ultrasonic vibrator, to overcome the obstacle of surface crystallinity. Through careful design, we have successfully improved the surface structure of ultra-high molecular weight polyethylene fibers, making it more conducive to full combination with coatings, thereby improving the coating effect. Therefore, this ultra-high molecular weight polyethylene coating device also solves the problems of poor coating effect, waste of resources and cost saving in the existing technology, and provides an innovative solution.

[0043] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0044] Example 1

[0045] A coating device for ultra-high molecular weight polyethylene fibers, such as Figure 1 As shown, the coating device includes a treatment box 1, an ultrasonic atomizer 2, a conveying roller 3 and an extrusion roller 4. The front and rear ends of the treatment box 1 are respectively provided with an inlet 6 and an outlet, and the inlet and the outlet are provided for ultra-high molecular weight polyethylene fibers to enter and exit the treatment box 1. A conveying roller 3 for conveying ultra-high molecular weight polyethylene fibers is provided at a position outside the treatment box 1 near the inlet, and an extrusion roller 4 for squeezing out excess coating liquid on the ultra-high molecular weight polyethylene fibers is provided at a position outside the treatment box 1 near the outlet. A plurality of ultrasonic atomizers 2 are provided above the treatment box 1, and the nozzles of the ultrasonic atomizers 2 face the inside of the treatment box 1; a window is provided at the lower side of the treatment box 1, and a lifting partition 7 is provided on the window. The lifting partition 7 can be opened to facilitate the treatment of equipment problems or entanglement inside the treatment box 1; when working, the lifting partition 7 is raised to separate the treatment box 1 to reduce the spray spillage.

[0046] A rectangular groove 5 for collecting the coating liquid is also provided at the bottom of the treatment box 1; the rectangular groove 5 is set to be removable. The length of the rectangular groove 5 outside the treatment box 1 is at least aligned with the squeezing roller 4, which can ensure that the coating liquid dripping from the squeezing roller 4 effectively falls into the rectangular groove 5. An oven 8 is also provided behind the treatment box 1, that is, near the squeezing roller 4. The front and rear ends of the oven 8 are both provided with an oven inlet and outlet 10. The interior of the oven 8 is provided with a heating wire for drying. The outer side of the oven 8 near the outlet is symmetrically provided with an outlet roller 9 for exporting the ultra-high molecular weight polyethylene fiber.

[0047] like Figure 2As shown, two wire separation racks, namely the first wire separation rack 11 and the second wire separation rack 12, are installed near the inlet of the processing box 1. The first wire separation rack 11 and the second wire separation rack 12 are used to separate the ultra-high molecular weight polyethylene fibers to avoid crossing. The first wire separation rack 11 and the second wire separation rack 12 have multiple tooth grooves. The first wire separation rack 11 and the second wire separation rack 12 are arranged in parallel and close to the inlet of the processing box. Below the ultrasonic atomizer 2, an ultrasonic vibration rod 13 is arranged inside the processing box 1. The ultrasonic vibration rod 13 is arranged parallel to the first wire separation rack 11 and the second wire separation rack 12. The ultrasonic vibration rod puts the ultra-high molecular weight polyethylene fibers in a vibrating state, making the fibers more conducive to fully combining with the coating, thereby improving the coating effect.

[0048] The schematic diagram of the spray head of the ultrasonic atomizer is as follows Figure 3 As shown, there are multiple micropores, so that the liquid is evenly atomized into fine mist particles, and by controlling the spray pressure and spray angle, the thickness and distribution of the coating can be accurately controlled, thereby reducing damage to the fiber. The feed pipe of the ultrasonic atomizer is connected to the coating liquid. Its working method is to transport the coating liquid to the ultrasonic atomizer through a pipeline, and the micropores inside the ultrasonic atomizer spray the liquid into fine particles, and then spray it evenly on the fiber surface through the spray head of the ultrasonic atomizer to achieve the coating effect. Its working principle is to use air pressure or vibration to disperse the liquid into tiny particles, and control the spraying method and density to achieve a uniform coating effect.

[0049] Preferably, multiple ultrasonic vibrating rods can be provided, and the multiple ultrasonic vibrating rods are arranged alternately at intervals of one above and one below, and the ultra-high molecular weight polyethylene fiber forms a "V" shape or a "W" shape after passing through. The arrangement of multiple ultrasonic vibrating rods reduces the surface crystallinity of the ultra-high molecular weight polyethylene fiber, makes the coating and the ultra-high molecular weight polyethylene fiber more firmly combined, and makes the spraying effect of the ultra-high molecular weight polyethylene fiber better.

[0050] The first wire separation frame 11 and the second wire separation frame 12 have the same structure, and the schematic diagram of the structure is shown in FIG. Figure 4As shown, each wire splitting frame includes a main shaft 14, a plurality of fork frames 15 and a control sleeve 16. The plurality of fork frames 15 are fixedly arranged in parallel at the front end of the main shaft 14. The end of the main shaft 14 is sleeved with the control sleeve 16. The control sleeve is provided with a positioning hole. The screw is tightened through the positioning hole to fix the main shaft. The screw is unscrewed and the position of the main shaft in the control sleeve is moved to realize the forward and backward movement of the wire splitting frame. One end of the control sleeve is embedded and fixed on the processing box, and the end with the positioning hole is leaked out of the processing box, so as to facilitate the adjustment of the forward and backward position of the wire splitting frame. A rotation positioning hole is provided on the end of the main shaft and the part inserted into the control sleeve. The positioning pin passes through the control sleeve to fix the rotation of the main shaft. When the positioning pin is inserted into the rotation positioning hole, the shaft is fixed. When the positioning pin is pulled out, the main shaft can rotate. Bearings can also be welded at both ends of the control sleeve. The main shaft passes through the bearings, so that the main shaft can rotate freely in the control sleeve.

[0051] The bearing and control sleeve can realize the rotation and forward and backward movement of the main shaft respectively. The adjustment method is to manually adjust the forward and backward movement of the two wire distribution frames respectively to make the ultra-high molecular weight polyethylene fiber pass smoothly and avoid the situation of getting stuck at the joint and winding and interlacing.

[0052] In this embodiment, when the ultra-high molecular weight polyethylene fiber coating device is working, during this process, the ultra-high molecular weight polyethylene fiber is routed through the conveying roller, through the inlet of the processing box, through two wire separation racks, ultrasonic vibration rods, the outlet of the processing box, the inlet of the oven, the outlet of the oven and the outlet roller. Start each component, the conveying roller provides the power for the ultra-high molecular weight polyethylene fiber to move, and then enter the processing box. In the process of passing through the processing box, the continuously moving ultra-high molecular weight polyethylene fiber is sprayed with a coating under the spraying action of the ultrasonic atomizer. Figure 2As shown in the figure, the ultra-high molecular weight polyethylene fiber passes through two self-adjusting wire splitting racks when entering the processor and continues to move. The wire splitting rack can prevent the ultra-high molecular weight polyethylene fiber from being entangled and interlaced inside the processing box and stuck at the joint point by adjustment, and then passes through the first ultrasonic vibrator, and then changes direction downward, passes through the second ultrasonic vibrator, and then changes direction upward, passes through the third ultrasonic vibrator. Through the action of the ultrasonic vibrator, the surface of the ultra-high molecular weight polyethylene fiber forms a rough structure, so that the bonding force between the surface of the ultra-high molecular weight polyethylene fiber and the coating is stronger, thereby improving the bonding tightness between the ultra-high molecular weight polyethylene fiber and the coating, and improving the coating effect of the ultra-high molecular weight polyethylene fiber. When the ultra-high molecular weight polyethylene fiber continues to move, it leaves the outlet of the processing box and is squeezed by the squeezing roller, thereby removing the excess coating on the ultra-high molecular weight polyethylene fiber, and moving the ultra-high molecular weight polyethylene fiber to the oven, entering the oven for drying under the action of the outlet roller, and exporting the ultra-high molecular weight polyethylene fiber from the outlet roller, thereby completing the coating operation of the ultra-high molecular weight polyethylene fiber. Excess coating can flow into the rectangular groove below; collect excess coating for recycling, saving costs.
