Description

Technical Field

[0001] The present application relates to the technical field of composite materials, and in particular to an epoxy resin composite material mixing device. Background Art

[0002] Nano-silica epoxy resin composite materials have high strength, toughness and ductility. In the production process of the above materials, a mixing device is usually used to mix epoxy resin and nano-silica for molding.

[0003] Some existing mixing devices are mainly composed of a cylinder, a cover and a stirring rod. When in use, epoxy resin (liquid) and nano-silicon dioxide (powder) are placed in the cylinder, and then the cover and the stirring rod are driven to move downward so that the stirring rod extends into the cylinder and the cover closes the cylinder. Finally, the stirring rod is rotated to mix the epoxy resin and nano-silicon dioxide in the cylinder. Through the above actions, the mixing operation of the two is completed.

[0004] However, when the stirring rod stirs the epoxy resin and the nano-silicon dioxide, they will be driven to rotate. Since the stirring rod is at a fixed height, the epoxy resin and the nano-silicon dioxide at the same height as the stirring rod will receive the best stirring effect, while the epoxy resin and the nano-silicon dioxide at other positions will receive a weaker stirring effect, thereby affecting the overall mixing quality of the epoxy resin and the nano-silicon dioxide. Summary of the invention

[0007] Furthermore, the stirring mechanism includes a rotating chamber, a rotating ring, a stirring rod No. 1, internal teeth, a gear and a power mechanism No. 1. The extrusion piece is provided with a rotating chamber inside, and the outer opening of the rotating chamber is provided on the outer surface of the extrusion piece. The rotating chamber is provided with a rotating ring for sealing and rotation inside, and the outer side surface of the rotating ring is provided with a stirring rod No. 1 at equal intervals in the circumference, and the inner side surface of the rotating ring is provided with internal teeth at equal intervals in the circumference. A gear is rotatably installed inside the extrusion piece and located at the inner side of the rotating chamber, and the gear is meshed with the internal teeth. A power mechanism No. 1 is provided inside the extrusion piece and located at the lower side of the gear, and the output shaft of the power mechanism No. 1 is fixedly connected with the gear.

[0008] Furthermore, the through-going mechanism is a material passing space, there is a material passing space between the inner wall of the cylinder and the outer side surface of the extrusion piece, and the No. 1 stirring rod is in the material passing space.

[0009] Furthermore, through holes are equidistantly provided inside the extrusion and on the inner side of the gear, and the through holes are set at an inclined angle. The upper opening of the through hole is opened on the outer side of the upper side of the extrusion, and the upper opening of the through hole faces the wall of the cylinder, and the lower opening of the through hole is opened on the inner side of the lower side of the extrusion, and the lower opening of the through hole faces the center of the inner cavity of the cylinder.

[0010] Furthermore, the rotation direction of the No. 1 stirring rod is opposite to the direction in which the material is ejected from the through hole.

[0011] Furthermore, the stirring mechanism includes a No. 2 power mechanism, a rotating shaft and a No. 2 stirring rod. The No. 2 power mechanism is arranged at the center position inside the extrusion member, and the rotating shaft is rotatably installed at the center position of the lower side of the extrusion member. The upper end of the rotating shaft is fixedly connected with the output shaft of the No. 2 power mechanism, and the No. 2 stirring rod is equidistantly arranged on the outer side surface of the rotating shaft.

[0012] Furthermore, the through mechanism includes an inner hole and an outer hole, the extrusion piece forms a sealed movable connection with the inner cavity of the cylinder, the inner side of the extrusion piece is provided with an inner hole penetrating vertically, and the outer side of the extrusion piece is provided with an outer hole penetrating vertically.

Through the above-mentioned action, the mixing effect of the materials in various places in the cylinder is achieved to be the same.

[0017] Through the arrangement of the extrusion piece and the through hole, in the process of the extrusion piece driving the material, the material at the center of the cylinder will enter the other side of the extrusion piece through the through hole, and then the material will collide with the material entering through the space between the cylinder and the extrusion piece. Through this action, the materials on both sides of the cylinder inside and outside are effectively mixed, so that the overall mixing quality of the materials is improved.

[0018] By setting the extrusion piece and the through hole, since the rotation direction of the No. 1 stirring rod is opposite to the injection direction of the material when passing through the through hole, when the materials on both sides of the cylinder body are mixed, the contact force of the materials on both sides is further increased, thereby improving the overall mixing quality of the materials.

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] Embodiment 1

[0030] See also Figure 1-Figure 3 A mixing device for epoxy resin composite materials comprises a workbench 1, support rods 2 (similar to the combination of a hydraulic cylinder and an output rod in the prior art) are welded on both sides of the upper surface of the workbench 1, a cylinder 3 is placed on the upper surface of the workbench 1 between the support rods 2 on both sides, the outer side of the cylinder 3 is fixedly connected with the cylinder body of the support rod 2, a cover 4 is placed at the upper opening of the cylinder 3, a lifting mechanism 5 (similar to the combination of a hydraulic cylinder and an output rod in the prior art) is fixedly installed on the upper side of the cover 4, a connecting plate is fixedly installed on the upper side of the lifting mechanism 5, both sides of the connecting plate are fixedly connected with the rod body of the support rod 2, an extrusion piece 6 is arranged at the center of the inner cavity of the cylinder 3, the output rod of the lifting mechanism 5 passes through the cover 4, and is welded and fixed to the center of the upper side of the extrusion piece 6, and the extrusion piece The upper side surface of 6 is inclined downward from the center position to the edge position, and there is a material passing space between the inner wall of the cylinder 3 and the outer side surface of the extrusion 6. A rotating cavity 7 is opened inside the extrusion 6, and the outer opening of the rotating cavity 7 is opened on the outer side surface of the extrusion 6. A rotating ring 8 is installed in the rotating cavity 7 in a sealed and rotatable manner. A stirring rod No. 9 is welded circumferentially and equidistantly on the outer side surface of the rotating ring 8. The stirring rod No. 9 is in the material passing space, and an inner side surface of the rotating ring 8 is welded circumferentially and equidistantly with internal teeth 10. A gear 11 is rotatably installed inside the extrusion 6 at the inner side of the rotating cavity 7, and the gear 11 is meshed with the internal teeth 10. A power mechanism No. 12 (such as a forward and reverse motor) is arranged inside the extrusion 6 at the lower side of the gear 11, and the output shaft of the power mechanism No. 12 is welded and fixed to the lower side surface of the gear 11.

[0031] When in use, the material (epoxy resin and nano-silicon dioxide) is placed in the cylinder 3, and then the support rod 2 drives the cover 4 and the extrusion piece 6 to move downward, so that the cover 4 closes the cylinder 3, and then the lifting mechanism 5 drives the extrusion piece 6 to move up and down reciprocatingly in the cylinder 3. At the same time, the No. 1 power mechanism 12 drives the gear 11 to rotate, so that the inner gear 10 drives the rotating ring 8 and the No. 1 stirring rod 9 to rotate synchronously. In the process of the extrusion piece 6 moving downward, the material at the bottom of the cylinder 3 will be squeezed, so that the material is discharged to the upper side of the extrusion piece 6 through the material passing space. Since the No. 1 stirring rod 9 is arranged in the material passing space, the probability of the material in the cylinder 3 forming an effective contact with the No. 1 stirring rod 9 is increased. Through the above action, the mixing effect of the materials in various places in the cylinder 3 is achieved to be the same. Afterwards, when the extrusion member 6 moves upward, the material at the upper side of the extrusion member 6 is affected by its own gravity and the extrusion force between the extrusion member 6 and the sealing cover 4, and then returns to the bottom of the inner cavity of the cylinder 3 through the material passing space, so that the material is stirred by the No. 1 stirring rod 9 again, thereby achieving the same mixing effect of the materials in various places in the cylinder 3.

[0032] See also Figure 2-Figure 5 The extrusion member 6 is internally provided with through holes 13 equidistantly arranged in the circumferential direction on the inner side of the gear 11. The through holes 13 are arranged at an inclined angle. The upper opening of the through hole 13 is provided on the outer side of the upper side of the extrusion member 6 and faces the wall of the cylinder 3. The lower opening of the through hole 13 is provided on the inner side of the lower side of the extrusion member 6 and faces the center of the inner cavity of the cylinder 3.

[0033] During the downward movement of the extruder 6, the material at the bottom center of the cylinder 3 will enter the upper side of the extruder 6 through the through hole 13, and then the material will collide with the material entering through the above-mentioned material passing space. Through this action, the materials on both sides of the cylinder 3 are effectively mixed, so that the overall mixing quality of the materials is improved.

[0034] The rotation direction of the stirring rod 9 is opposite to the direction in which the material is ejected from the through hole 13, so that during the mixing process of the materials inside and outside the cylinder 3, the contact force of the materials on both sides is further increased, thereby improving the overall mixing quality of the materials.

[0035] Embodiment 2

[0036] See also Figure 1 and Figure 6, an epoxy resin composite material mixing device, comprising a workbench 1, support rods 2 (similar to the combination of a hydraulic cylinder and an output rod in the prior art) are welded on both sides of the upper surface of the workbench 1, a cylinder 3 is placed on the upper surface of the workbench 1 between the support rods 2 on both sides, the outer side of the cylinder 3 is fixedly connected to the cylinder body of the support rod 2, a cover 4 is placed at the upper opening of the cylinder 3, a lifting mechanism 5 is fixedly installed on the upper side of the cover 4, the lifting mechanism 5 (similar to the combination of a hydraulic cylinder and an output rod in the prior art), a connecting plate is fixedly installed on the upper side of the lifting mechanism 5, both sides of the connecting plate are fixedly connected to the rod body of the support rod 2, an extrusion piece 6 is sealingly and slidably installed in the inner cavity of the cylinder 3, the output rod of the lifting mechanism 5 passes through the cover 4, and is welded and fixed to the center position of the upper side of the extrusion piece 6, and the upper side of the extrusion piece 6 extends from the center position to the side The edge position is set to be inclined downward, and an extension ring 14 is welded to the outer side of the lower side of the extrusion piece 6, and the outer side of the extension ring 14 forms a sealed sliding connection with the inner wall of the cylinder 3. A No. 2 power mechanism 15 (such as a motor) is set at the central position inside the extrusion piece 6, and a rotating shaft 16 is rotatably installed at the central position of the lower side of the extrusion piece 6. The upper end of the rotating shaft 16 is fixedly connected with the output shaft of the No. 2 power mechanism 15, and the distance from the lower end of the rotating shaft 16 to the bottom surface of the inner cavity of the cylinder 3 is greater than the distance from the lower side of the extension ring 14 to the bottom surface of the inner cavity of the cylinder 3. Through this arrangement, the rotating shaft 16 is prevented from contacting the bottom wall of the cylinder 3, which causes wear of the rotating shaft 16. A No. 2 stirring rod 17 is welded on the outer side of the rotating shaft 16 at equal intervals in the circumferential direction, and an inner hole 18 is opened through the inner side of the extrusion piece 6 from top to bottom, and an outer hole 19 is opened through the outer side of the extrusion piece 6 from top to bottom.

[0037] When the extruder 6 moves downward, it squeezes the material at the bottom of the inner cavity of the cylinder 3, causing the material to pass through the inner hole 18 and the outer hole 19, and then enter the upper side of the extruder 6. In this process, the second power mechanism 15 drives the rotating shaft 16 and the second stirring rod 17 to rotate, so that the above-mentioned material will be stirred by the second stirring rod 17 before passing through the inner hole 18 and the outer hole 19. Through the above-mentioned action, the mixing effect of the materials at various places in the cylinder 3 is the same. Afterwards, when the extruder 6 moves upward, the material on the upper side of the extruder 6 is affected by its own gravity and the extrusion force between the extruder 6 and the cover 4, and then passes through the inner hole 18. The material returns to the bottom of the inner cavity of the cylinder 3 through the outer hole 19, so that the material is stirred by the No. 2 stirring rod 17 again, thereby promoting the same mixing effect of the materials in various places in the cylinder 3. In addition, since the extrusion piece 6 forms a sealed sliding connection with the inner wall of the cylinder 3, the material will be filled in the space formed by the extrusion piece 6 and the cylinder 3 during the process of the extrusion piece 6 extruding the material, so that when the No. 2 stirring rod 17 stirs the material, the material is not easy to form a vortex (because a depression will appear in the center of the vortex, which will affect the amount of effective contact between the material and the No. 2 stirring rod 17), thereby promoting the same mixing effect of the materials in various places in the inner cavity of the cylinder 3.

[0038] See also Figure 6 The upper port of the inner hole 18 faces the wall of the cylinder 3, the lower port of the inner hole 18 faces the center of the inner cavity of the cylinder 3, the upper port of the outer hole 19 faces the center of the inner cavity of the cylinder 3, and the lower port of the outer hole 19 faces the wall of the cylinder 3.

[0039] Through the above arrangement, when the materials pass through the inner hole 18 and the outer hole 19 and enter the upper side of the extrusion member 6, mutual impact will occur, thereby further improving the overall mixing quality of the materials.
