Description

Technical Field

[0001] This utility model relates to the field of yarn impregnation technology, and in particular to a glass fiber yarn impregnation device. Background Technology

[0002] Glass fiber yarns, used as reinforcements in high-performance composite materials, typically require impregnation before practical application. This process aims to uniformly apply resins, coatings, or other modifiers to the yarn surface and fiber gaps to improve its interfacial bonding with the matrix material, impart specific functions (such as corrosion resistance and toughening), or prepare it for subsequent weaving and molding processes. Impregnation generally includes core steps such as immersion, removal of residual liquid, and curing and drying. The quality of this process directly affects the mechanical properties and reliability of the final composite product.

[0003] However, existing glass fiber yarn impregnation equipment and processes still have several shortcomings in practical applications. First, excessive impregnation liquid often adheres to the surface of the impregnated yarn. If this liquid is not removed sufficiently, it not only wastes raw materials but also causes bubbles, holes, or uneven curing of the impregnated layer due to the vigorous evaporation of solvents or low-boiling-point components during the drying stage, affecting the density of the coating. Second, traditional hot air drying methods typically use a single-path linear drying channel, which often requires a relatively long equipment size to achieve sufficient drying time, resulting in a large footprint and insufficient equipment compactness.

[0004] To address this, we propose a glass fiber yarn impregnation device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a glass fiber yarn impregnation device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a glass fiber yarn impregnation device, comprising a frame and a controller fixedly connected to one side of the frame, wherein a housing is fixedly connected between the inner walls of both sides of the frame, and an impregnation tank and a drying tank are provided at the bottom of the inner side of the housing;

[0007] The housing and the inner walls on both sides of the impregnation tank are equipped with several glass fiber yarn guide components, and the inner walls on both sides of the drying tank are equipped with one glass fiber yarn guide component.

[0008] The two inner walls of the impregnation tank are fixedly connected to a bottom plate, and a top plate is attached to the top of the bottom plate. Several liquid removal tanks are opened on the top of the bottom plate and the bottom of the top plate.

[0009] The top of the top plate is symmetrically fixedly connected to two fixing rods, and the top of the two fixing rods is fixedly connected to a top cover, which is detachably fixedly embedded in the top of the shell.

[0010] Two side electric heating plates are fixedly connected to the inner walls of both sides of the drying tank, and a middle electric heating plate is fixedly connected to the inner walls of both sides of the drying tank.

[0011] Furthermore, each of the aforementioned glass fiber yarn guiding components includes two bearing seats, and the seats of the bearing seats are respectively fixedly connected to the inner walls of the housing, the impregnation tank, and the drying tank on both sides. The inner rings of the bearings built into the two bearing seats are jointly fixedly connected to the yarn guiding roller. The bearing seats ensure that the yarn guiding roller rotates smoothly and with low resistance, thereby minimizing yarn wear during the guiding process.

[0012] Furthermore, two adjacent liquid removal tanks can be combined to form a complete conical hole. The conical hole structure can exert a progressive squeezing effect on the passing yarn, thereby more thoroughly and evenly scraping off the excess impregnation liquid adhering to its surface, reducing waste and improving the subsequent drying quality.

[0013] Furthermore, an observation window is provided on one side of the outer surface of the shell, and the observation window matches the immersion tank, making it convenient for operators to directly observe the changes in the liquid level in the immersion tank.

[0014] Furthermore, the top cover and the housing are detachably fixedly connected by several fasteners. An exhaust gas discharge pipe is fixedly connected to one side of the top of the housing, and the exhaust gas discharge pipe is located directly above the drying tank. The fastener connection method makes it convenient to open and close the top cover, which is conducive to cleaning, maintenance and other operations inside the equipment.

[0015] Furthermore, the bottom of the drying tank is designed to be open, and a square plate is provided below the drying tank. The square plate is detachably fixed to the bottom of the shell, making it easy to clean any solidified material or impurities that may drip into the drying tank.

[0016] Furthermore, the intermediate electric heating plate is located in the middle of the two side electric heating plates. The intermediate electric heating plate is located directly above the glass fiber yarn guide assembly in the drying tank. The two side electric heating plates are located directly below two adjacent glass fiber yarn guide assemblies in the housing. This arrangement ensures that the yarn has a heat source on both its left and right sides when it travels through the "S" shaped path.

[0017] The beneficial effects of this utility model are:

[0018] In use, this invention utilizes a separate design for the impregnation tank and the drying tank, along with specially arranged yarn guide rollers, to create a compact S-shaped drying and preheating path for the yarn within the drying tank. This significantly extends the contact time and heat exchange efficiency between the yarn and the hot air generated by the side and middle electric heating plates within a limited space, thereby achieving miniaturization and low energy consumption of the equipment. Simultaneously, the liquid removal tanks on the bottom and top plates effectively scrape away excess impregnation liquid from the yarn surface, preventing bubbles or holes from forming due to violent solvent evaporation during drying, thus ensuring the uniformity and density of the impregnation layer.

[0027] like Figures 1-4As shown, a glass fiber yarn impregnation device is disclosed, including a frame 1, a controller 4 fixedly connected to one side of the frame 1, a housing 3 fixedly connected between the inner walls of both sides of the frame 1, and an impregnation tank 7 and a drying tank 10 provided at the bottom of the inner side of the housing 3.

[0028] Several glass fiber yarn guide components are installed on both sides of the inner walls of the housing 3 and the impregnation tank 7. A glass fiber yarn guide component is installed on both sides of the inner walls of the drying tank 10. Each of the glass fiber yarn guide components includes two bearing seats 12. The seats of the bearing seats 12 are fixedly connected to the inner walls of the housing 3, the impregnation tank 7 and the drying tank 10 respectively. The inner rings of the bearings built into the two bearing seats 12 are fixedly connected to the yarn guide roller 6. The bearing seats 12 are sealed using existing fillers to ensure their performance.

[0029] The inner walls on both sides of the impregnation tank 7 are fixedly connected to a base plate 16. A top plate 14 is attached to the top of the base plate 16. Several liquid removal tanks 15 are provided on the top of the base plate 16 and the bottom of the top plate 14. Two adjacent liquid removal tanks 15 can be combined to form a complete conical hole. An observation window is provided on one side of the outer surface of the housing 3, and the observation window matches the impregnation tank 7. The observation window allows the operator to directly observe the liquid level changes and yarn impregnation status in the impregnation tank 7, realizing process visualization management. A ball valve that communicates with the impregnation tank 7 is fixedly connected to the bottom of the housing 3, which facilitates the discharge of impregnation liquid.

[0030] Two fixing rods 13 are symmetrically fixed to the top of the top plate 14. The top of the two fixing rods 13 are fixedly connected to the top cover 5. The top cover 5 is detachably fixedly embedded in the top of the housing 3. The top of the housing 3 has a positioning groove that matches the top cover 5, which facilitates the positioning and installation of the top cover 5. The top cover 5 and the housing 3 are detachably fixedly connected by several buckles. The buckle body is fixedly connected to the outer wall of the top cover 5, and the main body of the buckle is fixedly connected to the outer wall of the housing 3, which enables the quick installation and removal of the top cover 5. An exhaust gas discharge pipe 2 is fixedly connected to one side of the top of the housing 3. The exhaust gas discharge pipe 2 is located directly above the drying tank 10. The exhaust gas discharge pipe 2 is connected to the exhaust gas discharge pipeline used in the factory or to the existing exhaust gas treatment equipment, which is conducive to the exhaust gas emission treatment.

[0031] Two side electric heating plates 8 are fixedly connected to the inner walls of both sides of the drying tank 10, and a middle electric heating plate 9 is fixedly connected to the inner walls of both sides of the drying tank 10. The bottom of the drying tank 10 adopts an open design, and a square plate 11 is provided below the drying tank 10. The square plate 11 is detachably fixed to the bottom of the housing 3. The square plate 11 is fixed to the housing 3 with existing screws, which facilitates disassembly and cleaning of the drying tank 10. The middle electric heating plate 9 is located in the middle of the two side electric heating plates 8. The middle electric heating plate 9 is located directly above the glass fiber yarn guide assembly in the drying tank 10. The two side electric heating plates 8 are located directly below two adjacent glass fiber yarn guide assemblies in the housing 3. The middle electric heating plate 9 and the side electric heating plates 8 are both composed of heat-conducting elements and electric heating rods. The electric heating rods are embedded in the heat-conducting elements. The middle electric heating plate 9 and the side electric heating plates 8 are electrically connected to the controller 4, which facilitates the control of the middle electric heating plate 9 and the side electric heating plates 8.

[0032] Working principle: The glass fiber yarn to be processed is first guided to the yarn guide roller 6 located at the inlet of the device. Then, under the guidance of the yarn guide roller 6, the yarn enters the housing 3. Subsequently, under the action of the glass fiber yarn guide assembly near the impregnation tank 7 inside the housing 3 and the glass fiber yarn guide assembly inside the impregnation tank 7, the yarn enters the impregnation tank 7. The impregnation tank 7 is filled with impregnation liquid, and the yarn is completely immersed in the liquid to achieve full impregnation.

[0033] After impregnation, the fiberglass yarn guide assembly in the impregnation tank 7 and the fiberglass yarn guide assembly near the drying tank 10 in the housing 3 leave the liquid surface and pass upward through the channel formed by the combination of the bottom plate 16 and the top plate 14. The corresponding liquid removal grooves 15 on the bottom plate 16 and the top plate 14 together form a complete conical through hole. This hole scrapes the passing yarn, effectively removing most of the excess impregnation liquid carried on its surface and making the impregnation layer uniform.

[0034] After initial liquid removal, the yarn is guided by another set of glass fiber yarn guide components between the impregnation tank 7 and the drying tank 10, changing direction and entering the drying tank 10 area horizontally and vertically.

[0035] Inside the drying tank 10, the yarn passes through a hot air channel formed by two sets of side electric heating plates 8 and a middle electric heating plate 9 located in the middle. After the side electric heating plates 8 and the middle electric heating plate 9 are energized, they generate heat and provide a surrounding heating effect on the yarn, causing the remaining impregnation liquid on its surface to evaporate and solidify rapidly.

[0036] The high-temperature moisture and volatile substances generated during the drying process rise under the action of thermal convection and are eventually discharged to the outside of the device through the exhaust pipe 2 located directly above the drying tank 10.

[0037] After drying and curing, the yarn changes direction and exits the housing 3 under the guidance of the yarn guide roller 6 at the outlet of the drying tank 10, ready for winding.

[0038] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
