Detailed Implementation

[0018] See Figure 1 This utility model provides a variable width filament laying head, including a base 1; a pre-pressure wheel seat 2 is provided on the base 1, and a pre-pressure wheel 21 is installed at the bottom of the pre-pressure wheel seat 2; the pre-pressure wheel seat 2 is fixedly connected to the filament pressing seat 5, and a filament guiding channel is formed between the two; See Figure 3 and Figure 4 The preload wheel seat 2 is rotatably mounted with a guide roller 42, and the preload wheel seat 2 is also fixed with a guide motor 4 for driving the guide roller 42 to rotate; the pressure seat 5 is provided with a pressure roller 43 corresponding to the guide roller 42; Combination Figure 8 The opposite sides of the guide roller 42 and the pressure roller 43 extend into the guide channel. The two roller sides together squeeze the wire 101, causing it to extend along the width direction, while applying a guiding force to promote the transmission of the wire 101.

[0019] The pressing base 5 is also provided with a pressing roller cylinder 431 for driving the pressing roller 43 to approach or move away from the guide roller 42; when the pressing roller cylinder 431 retracts, the pressing roller 43 moves away from the guide roller 42, and a gap is formed between the two, through which the wire 101 can pass; when the pressing roller cylinder 431 extends, the pressing roller 43 approaches the guide roller 42, and the two together squeeze the wire 101, and the wire 101 is conveyed under the drive of the guide motor 4.

[0020] Furthermore, the guide motor 4 is a servo motor, which facilitates the adjustment of the rotational speed of the guide roller 42, ensuring the yarn is under appropriate tension and adapting to the laying speed. Even better, the guide motor 4 is connected to the guide roller 42 via a reducer 41.

[0021] Furthermore, a guide wheel 22 located at the entrance of the guide wire channel is installed on the preload wheel seat 2; the angle of the wire 101 is changed to allow it to smoothly enter the guide wire channel.

[0022] Furthermore, a scraper 44 is provided below both the pressing roller 43 and the guide roller 42; the blade of the scraper 44 faces the rotation direction of the roller side, and scrapes off the resin residue adhering to the pressing roller 43 and the guide roller 42 in real time, so as to avoid sticking to the yarn 101 and affecting the subsequent pressing quality.

[0023] Combination Figure 5 The outlet position of the guide wire channel has two adjusting blocks 231 that are slidably disposed on the preload wheel seat 2; The two adjusting blocks 231 are configured to change the gap between them by moving towards or away from each other, so that the gap is adapted to the width of the thread 101. Optionally, the adjustment block 231 of this utility model can be adjusted by manually pushing it to adjust the gap value between the two.

[0024] As one embodiment, the bottom of the preload wheel seat 2 is rotatably provided with an adjusting screw 232, and the two sides of the adjusting screw 232 are respectively threaded through the corresponding adjusting blocks 231; the threads of the adjusting screw 232 and the two adjusting blocks 231 are threaded with the same pitch and opposite directions; rotating the adjusting screw 232 can make the two adjusting blocks 231 move towards each other or away from each other, thereby changing the gap value of the adjusting blocks 231.

[0025] Furthermore, an adjustment knob 23 is fixedly connected to the end of the adjusting screw 232. Rotating the adjustment knob 23 can adjust the gap value between the two adjusting blocks 231. Even better, the surface of the adjustment knob 23 is also provided with a knurled structure to increase friction and facilitate gap adjustment.

[0026] See Figure 2The variable width fiber laying head also includes multiple parallel pressing rollers 3 with different thicknesses, each pressing roller 3 is connected to a pressing cylinder 32; each pressing cylinder 32 is fixed on a transverse moving seat 33; the seat body 1 is also equipped with a linear motor 31 for driving the transverse moving seat 33 to reciprocate in the horizontal direction; Each compaction roller 3 has a different thickness, corresponding to the width of the different specifications of the yarn 101. A linear motor 31 switches the compaction roller 3 to the width corresponding to the yarn 101, aligning it with the pre-compacting roller 21. Figure 8 After the yarn 101 is fed out from the guide channel, it is first pressed onto the mold 100 by the pre-pressing roller 21, and then the laying roller 3 lays the yarn 101 completely on the mold 100. The laying cylinder 32 of the laying roller 3 extends to provide pressure.

[0027] Combination Figure 9 When laying wires in grooves 102 with multiple widths, the pressing rollers 3 of corresponding thicknesses can be switched according to the different widths of the wires 101, enabling one machine to lay wires 101 of multiple widths and improving the efficiency of the laying operation.

[0028] After one type of yarn 101 is laid, the operator replaces it with a yarn of a different width 101. They then adjust the gap between the two adjusting blocks 231 and switch to the appropriate thickness pressing roller 3. The machine is then started, reducing manual labor and improving the accuracy and efficiency of yarn laying.

[0029] Even better, the thickness of the preloading roller 21 is no greater than the thickness of the thinnest compaction roller 3, so that the preloading roller 21 can be used for operations on rib grooves 102 of all widths.

[0030] As one embodiment, the wire pressing seat 5 is also equipped with a cutter cylinder 251, which is connected to a cutter 25 that can extend into the wire guide channel. When the wire 101 is laid to the edge of the mold 100, the cutter cylinder 251 actuates to extend the cutter 25 and cut the wire 101. During this process, the wire guide roller 42 and the wire pressing roller 43 remain in contact to clamp the wire 101 and prevent it from springing back. When the wire laying head switches to a new working position, the two rollers feed the wire 101 again to perform the wire laying operation.

[0031] As one embodiment, a hot air gun 11 is installed on the pre-pressing wheel seat 2, and a temperature probe 12 is installed on the wire pressing seat 5. During the wire laying operation, the hot air gun 11 sprays hot air to heat the surface of the mold 100, and the temperature probe 12 provides real-time feedback of temperature data to control the heating temperature.

[0032] See Figure 3As one embodiment, a slide rail seat 14 is fixed on the base 1, and a slide sleeve 24 that is slidably sleeved with the slide rail seat 14 is fixed on the pre-pressure wheel seat 2; a pre-pressure cylinder 13 for driving the slide sleeve 24 to reciprocate along the slide rail seat 14 is also installed on the base 1; during the wire laying operation, the pre-pressure cylinder 13 extends, the pre-pressure wheel seat 2 moves down, so that the pre-pressure wheel 21 presses the wire 101 onto the mold 100 with a certain pressure.

[0033] This invention's variable-width yarn-laying head features two adjustable blocks 231 at the outlet of the yarn guide channel, allowing for gap adjustment based on the yarn width specification. During yarn-laying, a pre-pressing roller 21 presses the yarn 101 onto the surface of the mold 100, and a pressing roller 3 corresponding to the yarn width is selected for complete laying. This invention enables the laying of yarns 101 of multiple widths using a single set of equipment, improving laying efficiency and expanding the equipment's application scenarios.

[0034] See Figure 6 The present invention also provides a laying device, including a material rack 6, on which at least one set of material rolls 61 and film take-up shafts 62 are installed; the material rack 6 is also connected to the variable width filament laying head; See Figure 7 In one embodiment, two opposing lifting plates 63 are fixed on the material rack 6, and both lifting plates 63 are fixed to the base 1 of the variable width filament laying head; a reversing wheel 64 is provided between the two lifting plates 63; combined with Figure 8 The material roll is installed on the material roll shaft 61, and the filament 101 is pulled out. The separator film is simultaneously wound onto the take-up shaft 62 and recycled. The filament 101 is guided into the guide channel of the variable width filament laying head by the reversing wheel 64.

[0035] The filament 101 of this invention can be a prepreg monofilament bundle of carbon fiber or glass fiber. Those skilled in the art can select the appropriate raw material filament bundle according to the specific product being manufactured.

[0036] In summary, this invention provides a variable-width yarn laying head. By setting two adjustable blocks with adjustable spacing at the outlet of the yarn guide channel, the gap can be adjusted according to the yarn width specification. During yarn laying, a pre-pressing roller is used to press the yarn onto the mold surface, and a pressing roller corresponding to the yarn width is selected for complete laying.
