Description

Technical Field

[0001] This invention relates to the field of rapid curing resin technology, specifically to a uniform impregnation device for rapid curing resin. Background Technology

[0002] In ancient times, people began using natural resins to treat materials and improve their properties. For example, natural lacquer (a type of natural resin) was applied to the surfaces of wood, ceramics, and other items for protection and decoration. This demonstrated that resins could combine with other materials to alter their appearance and properties. The Industrial Revolution of the late 18th and 19th centuries brought about the rapid development of the chemical industry. People began to synthesize various resin materials, such as phenolic resins and urea-formaldehyde resins. These synthetic resins have better properties and broader application prospects, providing a rich selection of materials for resin impregnation technology. For example, phenolic resins have good heat resistance and mechanical properties and can be used to impregnate fibrous materials to manufacture high-strength composite materials. Currently, in some industrial equipment components that need to withstand high pressure, resin-impregnated graphite blocks can better maintain structural integrity and are less prone to damage. Graphite blocks uniformly impregnated with resin need to be cured with the resin.

[0003] Currently, some small factories typically pre-set a fixed drying time for graphite discs. However, uneven temperature distribution often exists within the drying equipment. This temperature variation significantly impacts the resin curing process, potentially leading to slow curing or even incomplete curing. If insufficient curing is detected, the drying time needs to be readjusted, a tedious and inefficient process.

[0004] Combining the above issues, we find that existing resin impregnation equipment on the market cannot simultaneously avoid the problems mentioned above, thus failing to achieve the desired effect. Therefore, we propose a uniform impregnation device for rapidly curing resins. Summary of the Invention

[0005] The purpose of this invention is to provide a uniform impregnation device for rapidly curing resin, in order to solve the problem mentioned in the background art that the difference in temperature distribution can significantly affect the resin curing process, which may lead to slow resin curing speed or even incomplete curing. Once it is found that the resin curing is not up to standard, the drying time needs to be readjusted.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a uniform impregnation device for rapidly curing resin, comprising a drying chamber body, an inlet and an outlet fixedly installed on both sides of the drying chamber body, the drying chamber body, the inlet and the outlet being connected, a heating element fixedly installed inside the drying chamber body, and a drying lifting assembly and a drying raising assembly fixedly installed inside the drying chamber body, the drying raising assembly being mounted on the drying lifting assembly and used in conjunction with the drying raising assembly; The drying lifting assembly includes a T-shaped box slidably installed inside the main body of the drying chamber. The T-shaped box is used to place a graphite disc that is uniformly impregnated with resin. A rotating column is rotatably connected to the inner wall of the main body of the drying chamber. A drive gear is fixedly sleeved on the outer side of the rotating column. Several toothed blocks are fixedly connected to the side of the T-shaped box. The drive gear meshes with the toothed blocks for transmission. A fixing plate is fixedly connected to the side of the T-shaped box. A return spring is fixedly connected between the fixing plate and the bottom wall of the main body of the drying chamber. The top of the T-shaped box intermittently connects with the discharge port.

[0007] Furthermore, two guide grooves are provided on the inner wall of the drying oven body, and guide blocks are fixedly connected to both sides of the T-shaped box, with the guide blocks slidingly engaging with the guide grooves.

[0008] Furthermore, a fixing rod is fixedly installed at the bottom of the T-shaped box, and a piston disc is fixedly connected to the bottom of the fixing rod. A piston groove is opened in the bottom wall of the main body of the drying box, and the piston disc slides and engages with the piston groove.

[0009] Furthermore, an airflow groove is provided on the bottom wall of the main body of the drying oven, and the airflow groove is connected to the piston groove. An airflow pipe is fixedly connected between the T-shaped box and the bottom wall of the main body of the drying oven.

[0010] Furthermore, a pneumatic groove is provided inside the T-shaped box, and a T-shaped plate is slidably installed inside the pneumatic groove. A piston plate is fixedly connected to the bottom of the T-shaped plate, and the piston plate is slidably attached to the inner wall of the pneumatic groove. The pneumatic groove, the airflow pipe, and the airflow channel are connected in a continuous manner.

[0011] Furthermore, a protective plate is slidably installed on the side of the T-shaped box, the protective plate passes through the T-shaped box, and the protective plate is fixedly connected to the side of the T-shaped plate.

[0012] Furthermore, the drying lifting assembly includes a lifting plate that fits against the top of the T-shaped box, and two limiting grooves are opened on the inner wall of the drying box body. Limiting blocks are fixedly connected to both sides of the lifting plate, and the limiting blocks are slidably connected inside the limiting grooves.

[0013] Furthermore, a compression spring is fixedly connected between the limiting block and the limiting groove, and the compression spring is used to drive the lifting plate to fit against the top of the T-shaped box.

[0014] Furthermore, the T-shaped box has a through groove inside, which is connected to the interior of the drying box body. A lifting column is fixedly connected to the bottom wall of the drying box body. The lifting column slides in the through groove and intermittently contacts the graphite disc that is uniformly impregnated with resin.

[0015] Furthermore, the lifting plate is fitted to the graphite disk.

[0016] The technical solution provided by this invention has the following advantages compared with the known prior art: I. This invention, through the setting of a drying lifting component, allows the graphite disc, uniformly impregnated with resin, to descend when placed on top of a T-shaped box due to its weight. The heating element dries the graphite disc, and as the resin on the disc fully solidifies, the disc becomes lighter, allowing the top of the T-shaped box to fully align with the discharge port, and the disc slides out. The heating element begins operation immediately after the disc is positioned, enabling timely drying of the resin-impregnated graphite disc. Furthermore, since the lifting of the T-shaped box is controlled based on the weight change of the graphite disc itself, the disc is kept in a suitable position for stable heating, ensuring full resin curing and improving drying efficiency and product quality.

[0017] Second, by setting up a drying lifting component, the lifting plate and lifting column drive the graphite disc to lift part of it during the drying process. This process is repeated to avoid local overheating or uneven drying of the graphite disc due to prolonged static contact with the drying equipment. In this way, all parts of the graphite disc can be fully and evenly dried, ensuring the stability and consistency of drying quality and reducing the production of defective products.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] The present invention will be further described below with reference to embodiments.

[0023] Example: A uniform impregnation apparatus for rapidly curing resins, such as Figures 1-9As shown, the drying chamber includes a main body 1. An inlet 2 and an outlet 3 are fixedly installed on both sides of the main body 1. The inlet 2 is connected to a material supply source, and the outlet 3 is equipped with a conveying device. The main body 1, inlet 2, and outlet 3 are connected. A heating element 4 is fixedly installed inside the main body 1. It is worth noting that the heating element 4 is a heating component, commonly including infrared lamps and infrared ceramic heating plates. By heating infrared emitting materials such as tungsten wires and ceramics, its temperature rises, thereby radiating infrared rays. Infrared rays have a strong thermal effect; when infrared rays irradiate an object, the object absorbs the energy of the infrared rays, its molecular vibration intensifies, its internal energy increases, and its temperature rises. Drying lifting components 10 are fixedly installed inside the main body 1 of the drying chamber. When the graphite disc, which is uniformly impregnated with resin, enters the main body 1 of the drying chamber through the feed port 2 and is located on the drying lifting component 10, the graphite disc, which is uniformly impregnated with resin, squeezes the drying lifting component 10 to make it descend. When the resin is completely dried and cured, the moisture in the graphite disc is dried and its weight becomes lighter than that of the undried one. At this time, the drying lifting component 10 drives the graphite disc to rise and connects with the discharge port 3 to complete the discharge. The drying lifting assembly 10 includes a T-shaped box 101 slidably installed inside the drying chamber body 1. The top of the T-shaped box 101 is set as an inclined surface. The T-shaped box 101 is used to place a graphite disc uniformly impregnated with resin. When the top of the T-shaped box 101 is aligned with the discharge port 3, the graphite disc located on the top of the T-shaped box 101 can slide towards the discharge port 3 after drying. It is worth noting that the slope of the top of the T-shaped box 101 is relatively gentle, so the graphite disc will slide slowly on the top of the T-shaped box 101. A rotating column 104 is rotatably connected to the inner wall of the drying chamber body 1. A drive gear 105 is fixedly sleeved on the outer side of the rotating column 104. Several toothed blocks 106 are fixedly connected to the side of the T-shaped box 101. The drive gear 105 meshes with the toothed blocks 106 for transmission. A fixing plate 107 is fixedly connected to the side of the T-shaped box 101. A return spring 108 is fixedly connected between the fixing plate 107 and the bottom wall of the drying box body 1. When the graphite disc is completely solidified and becomes lighter, the return spring 108 is used to drive the T-shaped box 101 to rise, thereby causing the top of the T-shaped box 101 to intermittently connect with the discharge port 3. It should be noted that, since the drive gear 105 meshes with the toothed blocks 106, the T-shaped box 101 will not shift or experience uneven force when it moves up or down.

[0024] The drying oven body 1 has two guide grooves 102 on its inner wall. Guide blocks 103 are fixedly connected to both sides of the T-shaped box 101, and the guide blocks 103 slide and engage with the guide grooves 102. A fixing rod 109 is fixedly installed at the bottom of the T-shaped box 101, and a piston disc 110 is fixedly connected to the bottom of the fixing rod 109. A piston groove 111 is provided on the inner bottom wall of the drying oven body 1, and the piston disc 110 slides and engages with the piston groove 111. An airflow groove 112 is also provided on the inner bottom wall of the drying oven body 1, and the airflow groove 112 communicates with the piston groove 111. An airflow pipe 113 is fixedly connected between the T-shaped box 101 and the bottom wall of the drying oven body 1. A pneumatic groove 114 is provided inside the T-shaped box 101, and a T-shaped plate 1 is slidably installed inside the pneumatic groove 114. 15. A piston plate 116 is fixedly connected to the bottom of the T-shaped plate 115. The piston plate 116 slides against the inner wall of the pneumatic groove 114. The pneumatic groove 114, the airflow pipe 113, and the airflow groove 112 are connected. A protective plate 117 is slidably installed on the side of the T-shaped box 101. The protective plate 117 passes through the T-shaped box 101 and is fixedly connected to the side of the T-shaped plate 115. When the piston plate 116 moves upward, it drives the T-shaped plate 115 connected to it and the protective plate 117 on the side of the T-shaped plate 115 to move upward synchronously. Since the T-shaped box 101 is set as an inclined surface, the graphite disk will slide on the T-shaped box 101. The protective plate 117 moves upward, which plays a protective role for the uniformly impregnated resin graphite disk located on the T-shaped box 101.

[0025] Combined with appendix Figure 1 - Appendix Figure 9 It also includes a drying lifting assembly 20. When drying the graphite disc that is uniformly impregnated with resin, the drying lifting assembly 20 partially lifts the bottom sides of the graphite disc, forming a certain gap between the graphite disc and the T-shaped box 101. This allows hot air to flow more freely at the bottom and around the graphite disc, thereby improving the drying efficiency. The drying lifting assembly 20 includes a lifting plate 201 that fits against the top of the T-shaped box 101. Two limiting grooves 202 are opened on the inner wall of the drying box body 1. Limiting blocks 203 are fixedly connected to both sides of the lifting plate 201. The limiting blocks 203 are slidably connected inside the limiting grooves 202. A compression spring 204 is fixedly connected between the limiting blocks 203 and the limiting grooves 202. Normally, the compression spring 204 drives the lifting plate 201 to fit against the top of the T-shaped box 101. When the T-shaped box 101 descends and the top of the T-shaped box 101 is lower than the lowest point of the limiting groove 202, the lifting plate 201 separates from the top of the T-shaped box 101, and the graphite disk, half of which is located on the lifting plate 201, is tilted. The T-shaped box 101 has a through groove 205 inside, which is connected to the interior of the drying chamber body 1. The bottom wall of the drying chamber body 1 is fixedly connected to the lifting column 206. The lifting column 206 slides with the through groove 205 and intermittently contacts the graphite disk that is uniformly impregnated with resin. The lifting plate 201 fits against the graphite disk. When the top of the T-shaped box 101 is lower than the lowest point of the limiting groove 202 and continues to descend, the T-shaped box 101 slides down along the lifting column 206. At this time, the lifting column 206 gradually extends out of the through groove 205 and contacts the graphite disk.

[0026] Specifically, by setting up the drying lifting assembly 10, the graphite disc that is uniformly impregnated with resin is dried and cured. Operators can manually or using automated equipment to put the graphite disc that is uniformly impregnated with resin into the drying chamber body 1 from the feed port 2. At this time, the graphite disc is located on the T-shaped box 101. Due to the gravity of the graphite disc itself, the T-shaped box 101 is squeezed and the T-shaped box 101 is lowered. During this process, the guide blocks 103 on both sides of the T-shaped box 101 slide in the guide groove 102 to ensure the stability and accuracy of the descent process of the T-shaped box 101. Simultaneously, the fixed rod 109 connected to the bottom of the T-shaped box 101 drives the piston disc 110 to descend within the piston groove 111. As the piston disc 110 descends, the gas within the piston groove 111 is compressed. The gas flows through the airflow groove 112 and airflow pipe 113 to the pneumatic groove 114, pushing the piston plate 116 upward. As the piston plate 116 moves upward, it simultaneously drives the connected T-shaped plate 115 and the protective plate 117 on the side of the T-shaped plate 115 to move upward. Since the T-shaped box 101 is set to be inclined... The graphite disc slides on the T-shaped box 101. After the protective plate 117 moves up, it protects the graphite disc, which is uniformly impregnated with resin, on the T-shaped box 101, preventing the graphite disc from sliding out when the T-shaped box 101 passes the discharge port 3 during its descent. It should be noted that the initial position of the T-shaped box 101 is above the discharge port 3. When the graphite disc squeezes the T-shaped box 101 to move down, the protective plate 117 rises to block the graphite disc from sliding. Therefore, the graphite disc will not flow to the discharge port 3 before it is dried.

[0027] After the drying process is completed, the fully cured graphite disc loses moisture due to the complete curing of its internal resin, resulting in a lighter overall weight. Under the action of the return spring 108, the T-shaped box 101 partially resets and moves upward. During the upward movement of the T-shaped box 101, the fixed rod 109 and the piston disc 110 move upward synchronously. As the piston disc 110 moves upward, the pressure in the pneumatic groove 114 decreases, and the piston plate 116 moves downward under the action of air pressure, thereby driving the T-shaped plate 115 and the protective plate 117 to move downward. The protective plate 117 retracts, and the weight of the fully cured graphite disc causes the T-shaped box 101 to connect with the discharge port 3. Since the top of the T-shaped box 101 is set as an inclined surface, the fully cured graphite disc flows to the discharge port 3, completing the entire drying and curing process.

[0028] In the process of drying the graphite discs impregnated with resin evenly, the setting of the drying lifting assembly 20 plays a crucial role, providing a strong guarantee for achieving efficient and uniform drying results. Initially, the graphite disc is placed on the T-shaped box 101. Under the continuous action of its own gravity, the graphite disc exerts downward pressure on the T-shaped box 101, causing it to gradually descend. The lifting plate 201 in the drying lifting assembly 20, under normal conditions, is tightly fitted to the top of the T-shaped box 101 by means of the compression spring 204. As the T-shaped box 101 continues to descend, when the top of the T-shaped box 101 reaches below the lowest point of the limiting groove 202, the lifting plate 201 begins to separate from the top of the T-shaped box 101. The graphite disc on one side of the top of the T-shaped box 101 tilts. The tilt of the graphite disk creates a specific gap between it and the T-shaped box 101, which creates favorable conditions for the circulation of hot air. The hot air can flow more freely in the bottom and surrounding areas of the graphite disk, thereby accelerating the evaporation process of solvent or moisture on the surface and inside of the graphite disk. As the T-shaped box 101 continues to descend, and its top remains below the lowest point of the limiting groove 202, the T-shaped box 101 slides downward along the lifting column 206 fixed to the bottom wall of the drying chamber body 1. As the T-shaped box 101 descends, the lifting column 206 gradually extends out of the through groove 205 and comes into contact with the graphite disc. The lifting plate 201 and the lifting column 206 work together on the graphite disc. The lifting plate 201 provides support from one side, and the lifting column 206 applies an upward force from the bottom. The combined force of the two forces causes the originally tilted graphite disc to gradually return to a level state. At this time, the weight of the graphite disc is no longer borne by the T-shaped box 101, but is shared by the lifting plate 201 and the lifting column 206. Subsequently, the T-shaped box 101, now free from weight compression, begins to rise. During the rise, the T-shaped box 101 exerts a squeezing effect on the lifting plate 201. As the squeezing continues, the weight of the graphite disc is transferred back to the T-shaped box 101. When the T-shaped box 101 descends again, the whole process is repeated. Through this cyclical action, the state of the graphite disc changes continuously, sometimes tilting and sometimes leveling. Each change in state provides ample space for hot air to flow at the bottom of the graphite disc, allowing the hot air to fully contact all parts of the bottom of the graphite disc. This method effectively avoids uneven drying caused by insufficient local drying, ensuring the uniformity and efficiency of the drying effect, thereby improving the overall quality of graphite disc drying.
