Description

Technical Field

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

[0002] Basalt fiber: Continuous fiber drawn from natural basalt. It is produced by melting basalt rock at 1450℃~1500℃ and then drawing it at high speed through a platinum-rhodium alloy spinneret. Pure natural basalt fiber is generally brown in color. Basalt fiber is a new type of inorganic, environmentally friendly, high-performance fiber material, composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide, and titanium dioxide.

[0003] my country has listed basalt fiber as one of the four key fibers for development (carbon fiber, aramid fiber, ultra-high molecular weight polyethylene, and basalt fiber), and has achieved industrialized production. Continuous basalt fiber has been widely used in various fields such as fiber-reinforced composite materials, friction materials, shipbuilding materials, thermal insulation materials, the automotive industry, high-temperature filter fabrics, and protective applications.

[0004] Existing basalt fibers are generally drawn into continuous fibers at high speed, and then the fibers woven into large segments need to be bonded with an adhesive. However, gaps will remain between the woven basalt fibers. During the impregnation process, the performance of basalt fibers is often reduced due to incomplete impregnation.

[0005] Therefore, in view of these circumstances, there is an urgent need to develop a basalt fiber impregnation equipment to meet the needs of practical use. Utility Model Content

[0006] The purpose of this invention is to provide a basalt fiber impregnation device to solve the above-mentioned defects.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A basalt fiber impregnation device includes an impregnation tank with a recessed inner cavity for filling with adhesive. The impregnation tank contains several first fixed supports and several second fixed supports arranged in a linear array, alternating between the first and second fixed supports, in the middle of the impregnation tank. The bottom of each of the first and second fixed supports is provided with a rotatable first impregnation shaft and a second impregnation shaft, respectively. The first impregnation shaft extends through the first fixed supports to the bottom of the inner cavity, and the second impregnation shaft extends through the second fixed supports to the middle of the inner cavity. The bottom of the inner cavity is provided with several rotatable extrusion rollers, positioned below the first impregnation shafts.

[0008] In the above description, as a further embodiment, the first dip shaft, the second dip shaft, and the extrusion roller are all elongated structures, and the first dip shaft, the second dip shaft, and the extrusion roller are all parallel to each other.

[0009] In the above description, as a further embodiment, the two ends of the impregnation tank are inclined ramps, with the end of the ramp closest to the first fixed bracket and the second fixed bracket inclined inward.

[0010] As a further embodiment of the above description, a material placement rack is also included. The material placement rack is located at one end of the impregnation tank. Several rotatable material placement wheels are provided in the middle of the material placement rack. The material placement wheels are all parallel to each other. A rotatable guide hub is provided between two adjacent material placement wheels. The horizontal height of the guide hub is set above the material placement wheels.

[0011] As a further embodiment of the above description, several material feeding wheels are rotatably arranged on one side of the material feeding frame in a planar matrix structure.

[0012] As a further solution, the above description also includes a support frame, an impregnation tank is set inside the support frame, and a first splitter frame and a second splitter frame are respectively provided at the ends of the material rack and the support frame that are close to each other. Several splitter rollers are provided in the middle of the first splitter frame and the second splitter frame, and the splitter rollers are spaced at the same distance.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: A first fixed support and a second fixed support are arranged in a linear array structure inside the impregnation tank, and the first and second impregnation shafts can be positioned within the impregnation tank in a structure that alternates up and down multiple times. This allows the basalt fiber to be impregnated multiple times at the bottom of the impregnation tank as it passes over the first and second impregnation shafts. Simultaneously, a rotatable extrusion roller is located below the first impregnation shaft. When the basalt fiber passes under the first impregnation shaft, it is subjected to pressure and extrusion between the first impregnation shaft and the extrusion roller, causing the air gaps inside the basalt fiber to be expelled and the fiber to be fully impregnated with the adhesive. This equipment can improve the impregnation effect of basalt fiber and helps to improve the physical properties of basalt fiber in the weaving impregnation process. Attached Figure Description

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] For this embodiment, please refer to Figures 1-4 The specific implementation of the basalt fiber impregnation equipment includes an impregnation tank 2, the interior of which is a downwardly recessed cavity 24 for filling with adhesive. The impregnation tank 2 is provided with several first fixed supports 21 and several second fixed supports 22. The first fixed supports 21 and the second fixed supports 22 are arranged in a linear array structure in the middle of the impregnation tank 2. The bottom of the first fixed supports 21 and the second fixed supports 22 are respectively provided with a rotatable first impregnation shaft 211 and a second impregnation shaft 221. The first impregnation shaft 211 extends to the bottom of the cavity 24 through the first fixed supports 21, and the second impregnation shaft 221 extends to the middle of the cavity 24 through the second fixed supports 22. The bottom of the cavity 24 is provided with several rotatable extrusion rollers 23, which are located below the first impregnation shaft 211.

[0017] Specifically, the first impregnation shaft 211, the second impregnation shaft 221 and the extrusion roller 23 are all long strip structures, and the first impregnation shaft 211, the second impregnation shaft 221 and the extrusion roller 23 are all parallel to each other. The two ends of the impregnation tank 2 are inclined ramps 23, and the ramps 23 are inclined towards the first fixed bracket 21 and the second fixed bracket 22.

[0018] When the basalt fiber passes through the first impregnation shaft 211 and the second impregnation shaft 221 in sequence, it can be impregnated multiple times at the bottom of the impregnation tank 2. At the same time, a rotatable extrusion roller 23 is provided below the first impregnation shaft 211. When the basalt fiber passes under the first impregnation shaft 211, the basalt fiber can be squeezed between the first impregnation shaft 211 and the extrusion roller 23, so that the air gaps inside the basalt fiber are discharged and the adhesive is fully impregnated. This equipment can improve the impregnation effect of basalt fiber and help improve the physical properties of basalt fiber in the weaving impregnation process.

[0019] A further embodiment also includes a material rack 1, which is located at one end of the impregnation tank 2. The material rack 1 has several rotatable material rollers 11 in the middle, and the material rollers 11 are all parallel to each other. A rotatable guide hub 12 is provided between two adjacent material rollers 11. The horizontal height of the guide hub 12 is set above the material rollers 11. The material rollers 11 are rotatably arranged on one side of the material rack 1 in a planar matrix structure.

[0020] Multiple basalt fibers can be placed in the feeding wheels 11 by the feeding rack 1, and the basalt fibers can be pulled out towards the end of the feeding rack 1 near the impregnation tank 2 by the rotatable guide hub 12 between two adjacent feeding wheels 11. This allows multiple basalt fibers to be impregnated with glue at the same time in the impregnation tank 2, further improving the impregnation efficiency of the basalt fiber impregnation equipment.

[0021] In a preferred embodiment, a support frame 3 is also included. The impregnation tank 2 is disposed inside the support frame 3. The material rack 1 and the support frame 3 are respectively provided with a first splitter frame 13 and a second splitter frame 31 at their respective ends. The middle of the first splitter frame 13 and the second splitter frame 31 are provided with a plurality of splitter rollers 14, and the splitter rollers 14 are spaced at equal intervals.

[0022] By using the first branch frame 13 and the second branch frame 31, which are close to each other, the basalt fibers in the multi-layer feeding wheel 11 of the feeding frame 1 can be transported in layers, thus avoiding the situation of interlacing and messy between the multi-layer basalt fibers.

[0023] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
