[0029] The features and exemplary embodiments of each aspect of the present application will be described in detail below, in order to make the purpose, technical scheme and advantages of the present application more clear and apparent, the present application will be further described in detail below in combination with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by showing examples of the present application.

[0030] As shown in Figures 1 to 3 The present application provides a fiber bundle pultrusion preforming tool, which comprises a mounting seat 1 and a plurality of extrusion mechanisms 2. The mounting seat 1 comprises a base 11 and two limiting columns 12, the limiting columns 12 are vertically installed on the top surface of the base 11, and the two limiting columns 12 are spaced apart along the length direction of the base 11. The extrusion mechanism 2 is located between the two limiting columns 12, and the two ends of the extrusion mechanism 2 in the length direction thereof are respectively detachably connected with the two limiting columns 12, and the plurality of extrusion mechanisms 2 are vertically stacked in sequence; the adjacent extrusion mechanisms 2 are in close contact with each other, and the lowermost extrusion mechanism 2 is arranged on the top surface of the base 11; the bottom of the extrusion mechanism 2 is provided with an extrusion groove 21 allowing the fiber bundle to pass through along the width direction of the mounting seat 1, and the extrusion groove 21 for extruding the resin on the fiber bundle is recessed from the bottom surface of the extrusion mechanism 2 to the top surface of the extrusion mechanism 2.

[0031] Specifically, the plurality of extrusion mechanisms 2 are vertically stacked in sequence, the adjacent two extrusion mechanisms 2 are mutually attached, and the lowermost extrusion mechanism 2 is arranged on the top surface of the base 11, so that the bottom opening of the extrusion groove 21 is closed by the lower extrusion mechanism 2 or the bottom surface of the base 11, so that the extrusion groove 21 is formed as an extrusion hole capable of extruding the fiber bundle. After the fiber bundle passes through the extrusion groove 21 along the width direction of the mounting seat 1, the extrusion groove 21 can extrude the excess resin on the fiber bundle, and further control the resin content of the fiber bundle. If the extrusion groove 21 is blocked by the wool yarn, the connection between the extrusion mechanism 2 and the limiting column 12 is released, the extrusion mechanism 2 is appropriately moved upward, the spacing between the adjacent extrusion mechanisms 2 and the spacing between the extrusion mechanism 2 and the base 11 are increased, and then the wool yarn in the extrusion groove 21 is cleaned. Therefore, the extrusion mechanism 2 and the limiting column 12 are detachably connected, so that the spacing between the extrusion mechanisms 2 and the spacing between the extrusion mechanism 2 and the base 11 can be increased, which facilitates cleaning the wool yarn in the extrusion groove 21, and further saves time and labor for wool yarn cleaning work, thereby improving the production efficiency of the preforming process.

[0032] As Figure 2 shown, in some embodiments of the utility model, the one side of limiting column 12 to another limiting column 12 is the inner side of limiting column 12, the one side of limiting column 12 away from another limiting column 12 is the outer side of limiting column 12, the one side of limiting column 12 to another limiting column 12 is equipped with the slot 13 of card, the slot 13 is recessed from the inner side of limiting column 12 to its outer side, the height of slot 13 is consistent with the height of limiting column 12, the both ends of extrusion mechanism 2 in its length direction are detachably installed in two slot 13 respectively, and the end of extrusion mechanism 2 in its length direction is attached with the slot wall of corresponding slot 13.

[0033] Specifically, the inner side surface of the limiting column 12 is set as a vertically extending plane, and the inner side surfaces of the two limiting columns 12 are parallel to each other so that the spacing between the two limiting columns 12 is consistent. The limiting column 12 can be a rectangular parallelepiped, and the limiting column 12 and the base 11 are integrally formed. The base 11 can be a rectangular parallelepiped, and the top surface of the base 11 is set as a horizontal plane. The width of the limiting column 12 can be the same as the width of the base 11. And in the width direction of the base 11, the two side surfaces of the limiting column 12 are flush with the two side surfaces of the base 11 respectively. The slot 13 passes through the limiting column 12 vertically. Therefore, in the vertical direction, the height of the slot 13 is equal to the height of the limiting column 12. The slot 13 can be a rectangular parallelepiped slot, so the three slot walls of the slot 13 are all planar extending slot walls, and the three slot walls of the slot 13 can respectively fit with the ends of the extrusion mechanism 2 in its length direction. In this embodiment, the extrusion mechanism 2 can be detachably mounted on the mounting base 1 by the engagement of the clamping groove 13 with the end portion of the extrusion mechanism 2, making it easy to repeatedly disassemble and assemble the extrusion mechanism 2, thereby facilitating the cleaning of clogged yarn. In addition, the extrusion mechanism 2 can be connected to the limiting column 12 by means of a bolt connection or a clamp connection.

[0034] like Figure 2 、 Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the fiber bundle pultrusion preforming tooling also includes two extension plates 14, which are respectively connected to the inner side surfaces of the two limiting columns 12. The height of the extension plates 14 is consistent with the height of the limiting columns 12. The two extension plates 14 are spaced apart in the length direction of the base 11, and the side of the extension plate 14 facing the extrusion mechanism 2 is in contact with the extrusion mechanism 2.

[0035] Specifically, the fiber bundles arranged in a row can pass between the two extension plates 14. The two extension plates 14 can constrain the fiber bundles, so that the fiber bundles always maintain a preset width and prevent the fiber bundles from dispersing to both sides, so that the fiber bundles can be close to the size of the final product. Of course, those skilled in the art can determine the spacing between the opposite sides of the two extension plates 14 based on the fiber bundles, and the present invention does not impose any restrictions. For example, the spacing between the opposite sides of the two extension plates 14 can be 8mm-12mm, and the spacing between the inner sides of the two limiting columns 12 can be 16mm-24mm. Preferably, the extension plates 14 and the limiting columns 12 are integrally formed.

[0036] In some embodiments, the side of the pulling mechanism downstream of the extrusion mechanism 2 is defined as the rear side, the side away from the pulling mechanism is defined as the rear side, and the other two sides are the left side and the right side.

The side of the extension plate 14 facing the pulling mechanism is flush with the side of the limiting column 12 facing the pulling mechanism, and the side of the extension plate 14 away from the pulling mechanism is attached to the rear side of the extrusion mechanism 2, and the side of the extension plate 14 away from the pulling mechanism is flush with one of the slot side walls of the clamping groove 13.

[0037] As shown in Figure 1 and Figure 3 In some embodiments of the utility model, the fiber bundle pultrusion preform tool further comprises a pressing block 3, the pressing block 3 is located between the two limiting columns 12, the two ends of the pressing block 3 in the length direction thereof are detachably connected with the two clamping grooves 13 respectively, the pressing block 3 is arranged above the extrusion mechanism 2, the top surface of the pressing block 3 is flush with the top surface of the limiting column 12, and the end of the pressing block 3 in the length direction thereof is attached to the slot wall of the corresponding clamping groove 13.

[0038] Specifically, the pressing block 3 is a cuboid block, and the top surface and the bottom surface of the pressing block 3 are arranged to extend horizontally. The bottom surface of the pressing block 3 is attached to the top surface of the uppermost extrusion mechanism 2. Similar to the end of the extrusion mechanism 2, in the length direction of the base 11, the three sides of the end of the pressing block 3 are attached to the three slot walls of the clamping groove 13 respectively. The width of the pressing block 3 can be the same as the width of the extrusion mechanism 2, and the length of the pressing block 3 can be the same as the length of the extrusion mechanism 2. The pressing block 3 is detachably connected with the limiting column 12, for example, the pressing block 3 can be connected with the limiting column 12 by bolt connection or clamp connection and the like. The height of the pressing block 3 can range from 10mm to 25mm.

[0039] In the embodiment, the pressing block 3 can press all the extrusion mechanisms 2 tightly on the base 11, so that the extrusion mechanisms 2 can extrude the fiber bundle. When the extrusion groove 21 is blocked by the wool yarn, the pressing block 3 can be removed, and the extrusion mechanism 2 remains relaxed; then the position of the extrusion mechanism 2 is appropriately raised, so that the extrusion groove 21 is expanded, thereby facilitating the cleaning of the wool yarn.

[0040] As shown in Figure 1 and Figure 3 In some embodiments of the utility model, the top surface of the limiting column 12 is rotatably installed with a pressing block 4, the pressing block 4 can rotate between a non-pressing position away from the pressing block 3 and a pressing position capable of vertically pressing the pressing block 3; and when the pressing block 4 is located in the pressing position, the bottom surface of the pressing block 4 is attached to the top surface of the pressing block 3.

The height of the pressing block 4 can range from 5mm to 10mm. In the embodiment, when the wool needs to be cleaned, the pressing block 4 is first rotated from the pressing position to the non-pressing position, then the pressing block 4 is removed, and then the position of the extrusion mechanism 2 is appropriately adjusted to expand the extrusion groove 21. After the wool is cleaned, the extrusion mechanism 2 is returned to the original position, the pressing block 3 is reinstalled, and then the pressing block 4 is rotated from the non-pressing position to the pressing position to press the pressing block 3 and the extrusion mechanism 2. Therefore, the pressing block 4 can facilitate the cleaning of the wool.

[0042] As Figure 3 shown in some embodiments of the utility model, the pressing block 4 includes a pressing part 42 and a connecting part 41 connected with each other, the connecting part 41 is horizontally rotatably installed on the top surface of the corresponding limiting column 12 through a pin, and the side of the connecting part 41 away from the pressing part 42 is provided as a curved surface; the pressing part 42 can be rotated between the non-pressing position and the pressing position through the connecting part 41; and when the pressing part 42 is located at the pressing position, the bottom surface of the pressing part 42 is flush with the top surface of the pressing block 3.

[0043] Specifically, the width of the pressing part 42 and the width of the connecting part 41 are the same as the width of the limiting column 12. When the pressing part 42 is located at the pressing position, the side of the pressing part 42 away from the connecting part 41 is flush with the inner side of the limiting column 12. In addition, the side of the connecting part 41 away from the pressing part 42 is provided as a curved surface to prevent interference with other parts on site.

[0044] In some embodiments of the utility model, the extrusion mechanism 2 includes a preforming module 22 and two pads 23, the two ends of the preforming module 22 in the length direction thereof are located in the two clamping grooves 13 respectively, and the end of the preforming module 22 in the length direction thereof is flush with the groove wall of the corresponding clamping groove 13. The top surface and the bottom surface of the preforming module 22 are provided as horizontally extending. The two pads 23 are located in the two clamping grooves 13 respectively, and the pad 23 is flush with the groove wall of the corresponding clamping groove 13. The top surface and the bottom surface of the pad 23 are provided as horizontally extending, the top surface of the pad 23 is flush with the bottom surface of the preforming module 22, and the preforming module 22 and the two pads 23 define the extrusion groove 21. The height of the pad 23 is equal to the depth of the extrusion groove 21, the height of the pad 23 is less than the height of the preforming module 22, the width of the pad 23 is equal to the width of the preforming module 22, and the side of the pad 23 facing the extrusion groove 21 is flush with the inner side of the corresponding limiting column 12.

[0045] Specifically, the pad 23 and the preforming module 22 are both in the shape of a rectangular parallelepiped, and the top and bottom surfaces of the pad 23 are set to extend horizontally, while the top and bottom surfaces of the preforming module 22 are set to extend horizontally. The pad 23 fits in with the preforming module 22. Similar to the pressing block 3, when the end of the preforming module 22 in its length direction is installed in the card slot 13, the three surfaces of the preforming module 22 fit in with the three groove walls of the card slot 13 respectively. When the pad 23 is installed in the card slot 13, the side of the pad 23 facing the other limiting column 12 is flush with the inner side surface of the corresponding limiting column 12, and the other three surfaces of the pad 23 fit in with the three groove walls of the card slot 13 respectively.

For the upper extrusion mechanism 2, the bottom surface of the spacer 23 mates with the top surface of the lower preforming module 22. Preferably, the height of the spacer 23 ranges from 0.5 mm to 5 mm, meaning that the depth of the extrusion groove 21 or the height of the extrusion hole can range from 0.5 mm to 5 mm. Preferably, the height of the preforming module 22 ranges from 10 mm to 25 mm.

[0046] In some embodiments, the extrusion trough 21 includes a wire guide area 211 and two operating areas 212.

When the wool yarn needs to be cleaned, a tool is inserted into the operating area 212, and then the extrusion mechanism 2 is tilted to increase the distance between the extrusion mechanism 2 and the extrusion mechanism 2 below or the base 11. Therefore, the above-mentioned structural form of the extrusion mechanism 2 can facilitate the adjustment of its own position.

[0047] like Figure 6 As shown, in some embodiments of the present invention, the pad block 23 includes at least one pad layer 231; when the pad block 23 includes multiple pad layers 231, the multiple pad layers 231 are stacked vertically, and two adjacent pad layers 231 are fitted together, the top surface and the bottom surface of the pad layer 231 are set to extend horizontally, the pad layer 231 is fitted with the groove wall of the corresponding card slot 13, the width of the pad layer 231 is equal to the width of the preformed module 22, and the length of the pad layer 231 is equal to the depth of the card slot 13.

[0048] Specifically, when the depth of the extrusion groove 21 needs to be adjusted, the number of the cushion layers 231 can be adjusted so that the extrusion mechanism 2 can adapt to fiber bundles of more specifications.

[0049] In some embodiments of the present invention, the height of the cushion layer 231 ranges from 0.5 mm to 5 mm. Preferably, the height of the cushion layer 231 is 1 mm.

[0050] As Figure 1 and Figure 3 As shown in some embodiments of the utility model, the number of extrusion mechanisms 2 is three. Therefore, the fiber bundle pultrusion preforming tool of the utility model allows the passage of three or fewer fiber bundles. Of course, the extrusion mechanism 2 can also be two or more than three, and the utility model does not make any restrictions.

[0051] In some embodiments, the part of the base 11 for contacting the fiber bundle, the part of the preforming module 22 for contacting the fiber bundle, and the part of the cushion block 23 for contacting the fiber bundle are all chamfered.
