DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] Example 1

[0038] The embodiment of the present application discloses a honeycomb panel surface layer forming device. Figure 1 The surface layer includes a panel 13 and fiber strips 14 embedded in the panel 13, and each fiber strip 14 is integrated from a plurality of fibers. Figure 2The honeycomb panel surface layer forming device comprises an extruder 1 and a die head 2 fixedly connected to the output end of the extruder 1. The top of the die head 2 is provided with a fiber channel 21 for the fiber strip 14 to penetrate along its length direction. The die head 2 is provided with discharge ports on the inner walls on both sides of the fiber channel 21. The length direction of the discharge port is parallel to the length direction of the fiber channel 21. Two pressure rollers arranged at intervals are rotatably connected to the lower part of the die head 2 beside the discharge port. The ends of the pressure rollers are provided with a traction assembly for pulling the fiber strip 14 to move. During operation, the output end of the extruder 1 can extrude molten resin. After the resin enters the inside of the die head 2, the sheet-like resin material is outputted outward through the discharge ports on both sides of the die head 2. At the same time, the fiber strip 14 penetrates along the depth direction of the fiber channel 21, and the fiber strip 14 is located between the resin materials on both sides. Finally, the high-temperature resin material and the fiber strip 14 can be hot-melt bonded by the extrusion of the pressure roller, so that the surface layer with the fiber strip 14 embedded inside is continuously outputted outward under the action of the traction assembly.

[0039] Reference Figure 2 and Figure 3 , a mounting plate 3 is fixedly connected to the top of the die head 2 along its length direction; a plurality of guide cylinders 4 are evenly spaced and arranged on the mounting plate 3 along its length direction, and the guide cylinders 4 are cylindrical, and the axis of the guide cylinders 4 is parallel to the depth direction of the fiber channel 21, and each guide cylinder 4 can allow a bundle of fiber strips 14 to pass through. Rounded corners 41 are provided at both ends of the guide cylinder 4, so that the wear of the fiber strips 14 by the guide cylinder 4 can be reduced. A connecting column 42 is vertically fixedly connected to the outer wall of the guide cylinder 4, and a slider 12 is fixedly connected to the end of the connecting column 42; a slide groove 31 is provided on the mounting plate 3 along its length direction, and the slider 12 is slidably set in the slide groove 31, so that the guide cylinder 4 is slidably set on the mounting plate 3. Furthermore, the connecting column 42 is threadedly connected to the slider 12, so that the guide cylinder 4 can be detachably connected to the slider 12, so that the guide cylinder 4 is easily removed from the slider 12 and replaced.

[0040] Reference Figure 2 and Figure 4 A diamond-shaped telescopic frame 8 is provided on one side of the mounting plate 3, and the telescopic direction of the diamond-shaped telescopic frame 8 is parallel to the length direction of the mounting plate 3. The diamond-shaped telescopic frame 8 includes a plurality of connecting rods 81 and mounting rods 82 vertically arranged between the connecting rods 81, and the mounting rods 82 are rotatably connected to the connecting rods 81. The number of mounting rods 82 is the same as the number of guide cylinders 4, and each mounting rod 82 corresponds to a guide cylinder 4; the end of the mounting rod 82 is fixedly connected to the slider 12 on the corresponding guide cylinder 4, so that when the diamond-shaped telescopic frame 8 is telescoped, the slider 12 can drive the guide cylinder 4 to move synchronously, thereby adjusting the positions of all guide cylinders 4 at the same time, and the adjustment process is simpler and faster.

[0041] Reference Figure 2 and Figure 3A locking assembly 5 for fixing the guide cylinder 4 is provided between the guide cylinder 4 and the mounting plate 3. Two groups of locking assemblies 5 are provided, corresponding to the guide cylinders 4 at both ends of the mounting plate 3 respectively. The locking assembly 5 includes a connecting block 51 and a locking bolt 52. The connecting block 51 is fixedly connected to the outer wall of the guide cylinder 4 at the end of the mounting plate 3, and a threaded hole is provided on the connecting block 51. The locking bolt 52 is threadedly connected to the threaded hole, and one end of the locking bolt 52 passes through the threaded hole. Therefore, when the end of the locking bolt 52 is pressed against the mounting plate 3, the sliding of the connecting block 51 can be limited, so that the connecting block 51 and the guide cylinder 4 are fixed on the mounting plate 3; since the guide cylinders 4 at both ends of the mounting plate 3 are fixed, the diamond telescopic frame 8 cannot be telescoped, so that other guide cylinders 4 can be fixed at the same time.

[0042] Reference Figure 3 Further, in order to enhance the locking effect, the end of the locking bolt 52 close to the mounting plate 3 is connected to the tooth block 6 by rotating around its own axis; the side of the tooth block 6 away from the mounting plate 3 is fixedly connected to the guide column 61, and the guide column 61 is parallel to the locking bolt 52; the connecting block 51 is provided with a guide hole 511, and the guide column 61 is slidably penetrated in the guide hole 511, so that the tooth block 6 and the connecting block 51 are slidably connected; the side of the mounting plate 3 close to the connecting block 51 is fixedly connected to the rack 7 along its own length direction. The locking bolt 52 can be rotated to make the end of the locking bolt 52 move toward the side close to the mounting plate 3. At this time, under the restriction of the guide hole 511 on the guide column 61, the tooth block 6 cannot rotate, so the tooth block 6 can move toward the side close to the mounting plate 3 together with the end of the locking bolt 52, until the tooth block 6 and the rack 7 on the mounting plate 3 are abutted, and the tooth block 6 and the rack 7 are meshed. At this time, the rack 7 can limit the sliding of the tooth block 6, thereby limiting the sliding of the connecting block 51 and the guide cylinder 4, thereby enhancing the locking effect.

[0043] A scale bar 9 is fixedly connected to the mounting plate 3 along its length direction, so that the position of each guide cylinder 4 can be easily observed and adjusted as needed.

[0044] Reference Figure 2 A support rod 11 is fixedly connected to the bottom of each guide cylinder 4, and an auxiliary cylinder 10 is fixedly connected to the end of the support rod 11 away from the guide cylinder 4. The auxiliary cylinder 10 and the guide cylinder 4 have the same shape, and the auxiliary cylinder 10 and the guide cylinder 4 are coaxially spaced; therefore, the fiber strip 14 can pass through the guide cylinder 4 and the auxiliary cylinder 10 in turn, and then enter the die head 2 through the fiber channel 21 to participate in the forming of the surface layer.

[0045] The implementation principle of Example 1 is: according to the required strength of the surface layer, the appropriate number of fiber strips 14 and the spacing between each fiber strip 14 are selected, and then the diamond telescopic frame 8 is extended or shortened accordingly. When the diamond telescopic frame 8 is movable, the guide cylinder 4 can be driven to move together through the mounting rod 82 and the slider 12, so that all guide cylinders 4 can be adjusted at the same time. After the diamond telescopic frame 8 is extended and retracted, the locking bolts 52 at both ends of the mounting plate 3 are rotated in sequence, so that the tooth block 6 slides to the side close to the rack 7, and the tooth block 6 is pressed against the rack 7, so that the guide cylinders 4 at both ends can be fixed; at this time, the diamond telescopic frame 8 cannot be extended and retracted, so the other guide cylinders 4 can be fixed, thereby completing the adjustment of the spacing between the guide cylinders 4.

[0046] Then, the fiber strip 14 is passed through the guide cylinder 4 and the auxiliary cylinder 10 in turn, and then the fiber strip 14 is introduced into the fiber channel 21; then the extruder 1 extrude the molten resin and output the resin to the die 2; the die 2 then extrude the resin through the discharge ports on both sides, thereby outputting two sheets of spaced-apart resin materials on both sides of the fiber strip 14; then the sheet-like resin material and the middle fiber strip 14 pass between the two pressure rollers, thereby forming a surface layer with the fiber strip 14 embedded in it at the output end of the pressure roller; then, under the action of the traction component, the surface layer can be moved toward the next process.

[0047] Example 2

[0048] Reference Figure 5 , the difference between this embodiment and embodiment 1 is that the number of locking assemblies 5 in this embodiment is the same as the number of guide cylinders 4, and each locking assembly 5 corresponds to a guide cylinder 4. The locking assembly 5 includes a connecting block 51, a plug rod 53 and a spring 54. The connecting block 51 is fixedly connected to the outer wall of the corresponding guide cylinder 4, and a mounting hole is provided on the connecting block 51, and the plug rod 53 is slidably inserted into the mounting hole. A plurality of plug holes 32 are evenly spaced along the length direction of the mounting plate 3 near the connecting block 51, and the plug holes 32 are parallel to the mounting holes. The spring 54 is fixedly connected between the end of the plug rod 53 and the connecting block 51, and the spring 54 is in a stretched state; when the mounting hole and the plug hole 32 are in a coaxial position, the spring 54 allows the end of the plug rod 53 to be inserted into the plug hole 32, which can limit the movement of the connecting block 51, thereby fixing the connecting block 51 and the guide cylinder 4 on the mounting plate 3.

[0049] Furthermore, one end of the insertion rod 53 close to the mounting plate 3 is configured to be hemispherical, so that the insertion rod 53 is not easily stuck during the process of being inserted into the insertion hole 32 .

[0050] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
