Description

Technical Field

[0001] This invention belongs to the field of fiber material preparation technology, specifically a rapid impregnation device for fiber material preparation. Background Technology

[0002] Fiber materials are a class of materials that exist in the form of continuous or discontinuous filaments and possess characteristics such as high strength, high modulus, and lightweight. Their materials include natural fibers, chemical fibers, and composite fibers. These materials are widely used in textiles, aerospace, medical devices, construction, and other fields. Their core function is to improve the key properties of end products, such as strength, toughness, and wear resistance, through their own structural characteristics or by combining them with other materials.

[0003] Impregnation is one of the core processes in the preparation of fiber materials. Its core purpose is to allow the fiber surface to uniformly absorb impregnation liquids such as resins, adhesives, and functional additives. Through the bonding and modification effects of the impregnation liquid, the bonding force between fibers is enhanced, or the fibers are endowed with special properties such as corrosion resistance, flame retardancy, and antibacterial properties, laying the foundation for subsequent molding and processing. Whether it is breathable fiber fabrics used in spinal orthotics or high-strength composite materials in the aerospace field, impregnation treatment is necessary to optimize their performance.

[0004] In existing technologies, the impregnation treatment of fiber materials mostly adopts the method of direct immersion, that is, the fiber material is placed directly in the impregnation liquid, and the adsorption is achieved by relying on the capillary action and gravity of the liquid. However, this method is prone to the existence of voids and entanglement inside the fiber bundle, and the impregnation liquid is difficult to penetrate into the core area of ​​the fiber, which easily leads to the problem of sufficient surface wetting but insufficient internal wetting. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a rapid impregnation device for the preparation of fiber materials, which effectively solves the problem of poor impregnation effect of current fiber materials.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rapid impregnation device for the preparation of fiber materials, comprising an impregnation tank, wherein the impregnation tank is provided with a tensioning mechanism;

[0007] The tensioning mechanism includes a U-shaped rod fixed to the bottom wall of the immersion tank. A movable frame located inside the immersion tank is movably sleeved on the outer side of the U-shaped rod. Two support rollers are symmetrically rotatably connected to the inner side of the movable frame. A lifting frame located inside the immersion tank is movably sleeved on the outer side of the U-shaped rod. Two bottom frames are symmetrically fixedly connected to the bottom of the lifting frame. Squeeze rollers are rotatably connected to the inner side of each of the two bottom frames. The two support rollers are located directly below the two squeeze rollers.

[0008] Preferably, the movable frame is symmetrically rotatably connected to two side rollers, both of which abut against the inner wall of the impregnation tank. The side rollers reduce the frictional resistance when the movable frame slides, while also providing precise positioning for the movable frame to prevent it from shifting or tilting, ensuring that the support roller and the extrusion roller are always aligned, resulting in more uniform fiber extrusion and consistent impregnation.

[0009] Preferably, two outer rings are symmetrically fixedly sleeved on the outer side of the U-shaped rod. Springs are fixedly connected between the bottom of each outer ring and the top of the movable frame. Both springs are sleeved on the outer side of the U-shaped rod, and both outer rings are located below the lifting frame. The springs provide continuous elastic force, which, in conjunction with the outer rings' limiting action, allows the support roller to adapt to the fiber thickness, resulting in a tighter compression and adhesion without damaging the fibers, effectively facilitating the penetration of the impregnation solution into the fiber core.

[0010] Preferably, a sleeve plate is fixedly sleeved on the outer middle of the U-shaped rod. Two diagonal braces are symmetrically fixedly connected between the sleeve plate and the top of the impregnation tank. An electric push rod is fixedly installed at the bottom of the sleeve plate, and the top of the lifting frame is fixed to the output end of the electric push rod. The diagonal braces enhance the load-bearing stability of the sleeve plate, and the electric push rod enables precise and controllable lifting of the extrusion roller, allowing for flexible adjustment of tension, adaptability to different types of fiber materials, and improved equipment versatility and ease of operation.

[0011] Preferably, a guide plate is fixedly connected to the inner bottom wall of the impregnation tank, and a drain pipe is fixedly connected to the outer side of the impregnation tank near the bottom. The guide plate guides the impregnation liquid to converge towards the drain pipe, avoiding liquid accumulation and residue. The drain pipe can quickly drain the waste liquid, facilitating equipment cleaning, impregnation liquid replacement, and subsequent maintenance, and greatly improving operating efficiency.

[0012] Preferably, the impregnation tank has an inlet and an outlet on each side, and guide rollers are rotatably connected to the inner sides of both the inlet and the outlet. The guide rollers can reduce frictional damage when the fibers enter and exit, accurately guide the fiber trajectory, ensure that the fibers pass smoothly through the extrusion roller and the support roller, ensure a continuous and smooth impregnation process, and avoid fiber entanglement or deviation.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The cooperation between the electric push rod and the lifting frame, as well as the U-shaped round rod and the bottom frame, facilitates the descent of the two extrusion rollers to tension the fiber material. The cooperation between the movable frame, the U-shaped round rod, the support roller, the spring and the outer ring facilitates the extrusion of the fiber material to avoid gaps and entanglement inside the fiber bundle, thereby improving the impregnation effect of the fiber material.

[0015] 2. The guide rollers and the inlet and outlet facilitate the entry and exit of fiber materials into and out of the impregnation tank for impregnation, and the guide plate and drain pipe facilitate the complete discharge of impregnation liquid from the impregnation tank.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1, by Figures 1-2 The present invention relates to a rapid impregnation device for the preparation of fiber materials, comprising an impregnation tank 1, wherein the impregnation tank 1 is provided with a tensioning mechanism 2.

[0024] Specifically, by Figure 3 The tensioning mechanism 2 includes a U-shaped rod 201 fixed to the bottom wall of the impregnation tank 1. A movable frame 2011 located inside the impregnation tank 1 is movably sleeved on the outer side of the U-shaped rod 201. Two support rollers 209 are symmetrically rotatably connected to the inner side of the movable frame 2011. A lifting frame 204 located inside the impregnation tank 1 is movably sleeved on the outer side of the U-shaped rod 201. Two bottom frames 205 are symmetrically fixedly connected to the bottom of the lifting frame 204. Squeeze rollers 2010 are rotatably connected to the inner side of each of the two bottom frames 205. The two support rollers 209 are located directly below the two squeeze rollers 2010.

[0025] Two side rollers 208 are symmetrically rotatably connected to the outer side of the movable frame 2011. Both side rollers 208 abut against the inner wall of the immersion tank 1. When the movable frame 2011 slides along the U-shaped rod 201, it drives the two side rollers 208 to roll on the inner wall of the immersion tank 1, thereby limiting the movable frame 2011 to ensure its stability during movement. Two outer rings 206 are symmetrically fixedly sleeved on the outer side of the U-shaped rod 201. Springs 207 are fixedly connected between the bottom of the two outer rings 206 and the top of the movable frame 2011. Both springs 207 are sleeved on the outer side of the U-shaped rod 201, and both outer rings 206 are located below the lifting frame 204.

[0026] A sleeve plate 202 is fixedly sleeved on the middle of the outer side of the U-shaped round rod 201. Two diagonal braces 2012 are symmetrically fixedly connected between the sleeve plate 202 and the top of the immersion tank 1. The diagonal braces 2012 are used for stable support of the sleeve plate 202. An electric push rod 203 is fixedly installed at the bottom of the sleeve plate 202. The top of the lifting frame 204 is fixed to the output end of the electric push rod 203.

[0027] When the electric push rod 203 is activated, the two extrusion rollers 2010 can move downward to tension the fiber material and extrude it, thereby improving the impregnation effect.

[0028] Specifically, by Figure 2 As shown, a guide plate 3 is fixedly connected to the inner bottom wall of the impregnation tank 1, and a drain pipe 4 is fixedly connected to the outer side of the impregnation tank 1 near the bottom. A solenoid valve is installed on the drain pipe 4. An inlet 6 and an outlet 7 are respectively provided on both sides of the impregnation tank 1. Guide rollers 5 are rotatably connected to the inner side of both the inlet 6 and the outlet 7.

[0029] By setting guide roller 5, inlet 6 and outlet 7, the fiber material is guided, which facilitates the fiber material to pass through impregnation tank 1 for impregnation operation. The guide plate 3 plays the role of guiding the flow. When the solenoid valve on the drain pipe 4 is opened, the impregnation liquid used in impregnation tank 1 is completely discharged from the drain pipe 4.

[0030] Working principle: First, the fiber material is passed between the extrusion roller 2010 and the support roller 209. Then, the electric push rod 203 is activated, which drives the lifting frame 204 to slide down along the U-shaped rod 201. The two bottom frames 205 drive the two extrusion rollers 2010 to descend, pushing the fiber material to make it taut. When the fiber material is pushed to abut against the two support rollers 209, the two extrusion rollers 2010 continue to descend, driving the two support rollers 209 to move downward, and driving the movable frame 2011 to slide down along the U-shaped rod 201. At this time, both springs 207 are deformed until the lifting frame 204 abuts against the two outer rings 206.

[0031] At this point, the two support rollers 209 are tightly bonded to the fiber material under the elastic force of the two springs 207. Finally, the fiber material is squeezed by the support rollers 209 and the extrusion rollers 2010 to avoid gaps and entanglement inside the fiber bundle, so as to facilitate the penetration of the impregnation liquid into the fiber core area and improve the impregnation effect.

[0032] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments; based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
