[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Please see Figure 1 - Figure 5This embodiment of a production fixture for carbon fiber safety helmets includes a processing platform 1, a gantry frame 2, a pressure base 20, a manual hot air assembly, an automatic hot air assembly, and an adjustment assembly. Both the manual and adjustment assemblies are mounted on the gantry frame 2, while the automatic hot air assembly is located below it. The automatic hot air assembly includes a blower plate 17. A hot air host 10 is fixedly mounted on the processing platform 1, and a hot air transmission pipe 11 is fixedly connected to the outlet of the hot air host 10. The other end of the hot air transmission pipe 11 is connected to the adjustment assembly. A telescopic cylinder 3 is fixedly mounted on the gantry frame 2. The telescopic end of cylinder 3 is fixedly connected to a lower pressure frame 4. The lower end of the lower pressure frame 4 is fixedly connected to a pressure ring 5. Two second telescopic cylinders 23 are fixedly installed on the lower pressure frame 4. The telescopic ends of the two second telescopic cylinders 23 are fixedly connected to the upper end face of the blower plate 17. The upper end of the blower plate 17 is provided with a blower plate air inlet hole 18. A wind cavity is provided inside the blower plate 17. Multiple hot air nozzles 19 are fixedly installed at equal intervals on the inner wall of the blower plate 17. The air inlet ends of the multiple hot air nozzles 19 are all located in the wind cavity. A wind plate pipe is fixedly inserted into the wind plate air inlet hole 18. The other end of the wind plate pipe is connected to the adjustment component. The safety helmet is placed on the pressure seat 20, and then the carbon fiber composite yarn is placed on the surface of the safety helmet. After the pressure ring 5 presses down to achieve the adhesion of the yarn to the surface of the safety helmet, the two No. 2 telescopic cylinders 23 can be activated to push the air blowing plate 17 downwards, so that the multiple hot air nozzles 19 on the inner wall of the air blowing plate 17 approach the yarn. Then, the hot air host 10 is activated so that its hot air passes through the hot air transmission pipe 11 and is guided into the air plate pipe by the adjustment component. The air plate pipe guides the hot air to the air inlet hole 18 of the air plate so that it fills the air cavity. The multiple hot air nozzles 19 can then blow the hot air in the air cavity outward to heat the yarn. The entire process only requires manual placement of the yarn on the surface of the safety helmet. The subsequent pressing and heating and bonding of the yarn can be completed automatically. The degree of intelligence is high and the processing efficiency is effectively improved.

[0019] The adjustment component includes a switching disk 7, with a switching shaft 6 fixedly connected to the upper end of the switching disk 7. The switching shaft 6 is rotatably connected to the inner wall of the gantry 2. A connector 12 is fixedly connected to the end of the hot air transmission pipe 11 away from the air outlet of the hot air host 10. A locking block 13 is fixedly connected to the side wall of the connector 12. A first air inlet 8 and a second air inlet 9 are opened at the upper end of the switching disk 7. The inner walls of the first air inlet 8 and the second air inlet 9 are provided with a slot 14 that matches the locking block 13. The end of the air plate pipe away from the air plate air inlet 18 is fixedly connected to the inner wall of the first air inlet 8. By setting the adjustment component, before the hot air host 10 delivers hot air to the outside through the hot air transmission pipe 11, the manual hot air component or the automatic hot air component can be selected according to the actual processing situation. When the automatic hot air component is needed, the hot air transmission pipe 11 can be inserted into the first air inlet 8 through the connector 12, so that the locking block 13 moves along the inner wall of the slot 14 and rotates to the deepest point. At this time, the hot air transmission pipe 11 is connected to the connector 12 in the first air inlet 8 through the connection of the locking block 13 and the slot 14. The hot air in the first air inlet 8 can be guided to the automatic hot air component through the air plate pipe connected below to achieve the hot air supply to the automatic hot air component. When using the manual hot air component, the connector 12 can be inserted into the second air inlet 9 in the same way to achieve the hot air supply to the manual hot air component.

[0020] The manual hot air assembly includes a hot air gun 16. A hook is fixedly connected to the side wall of the gantry 2. The hot air gun 16 is mounted on the hook. A gun tube 15 is fixedly inserted into the air inlet of the hot air gun 16. The other end of the gun tube 15 is fixedly connected to the inner wall of the second air inlet 9. The lower opening of the first air inlet 8 matches the size of the air plate tube. The lower opening of the second air inlet 9 matches the size of the gun tube 15. By setting up a manual hot air component, when it is necessary to attach a piece of gauze to a single area on the safety helmet, the hot air delivered by the hot air host 10 can be directed to the air gun tube 15 by adjusting the component. At this time, the worker can take off the hot air gun 16 from the hook and hold it to heat the single area independently, making the function of attaching the gauze of the safety helmet with hot air more powerful and effective.

[0021] Among them, both the air deflector tube and the air gun tube 15 are elastic high-temperature resistant telescopic tubes; By setting the air deflector tube and the air gun tube 15 as elastic high-temperature resistant telescopic tubes, the high temperature resistance can ensure the delivery of hot air and reduce the aging of the air deflector tube and the air gun tube 15. In addition, when using the automatic hot air assembly and the manual hot air assembly, the air deflector tube and the air gun tube 15 will be pulled. The telescopic nature can ensure that the air deflector tube and the air gun tube 15 deliver hot air more stably.

[0022] Among them, two No. 3 telescopic cylinders are fixedly installed inside the pressure base 20, and the telescopic ends of the two No. 3 telescopic cylinders are fixedly connected to the ejector head 24. By setting up an ejector head 24 and two No. 3 telescopic cylinders, the two No. 3 telescopic cylinders can complete the gauze application of the safety helmet on the pressure seat 20, and then push the ejector head 24 upward through the telescopic end to achieve the ejection and unloading of the safety helmet.

[0023] Among them, the upper end face of the processing platform 1 is fixedly connected to two guide frames 21, and each guide frame 21 is fixedly connected to a slide rod 22. Each slide rod 22 is slidably sleeved with a displacement block, and both displacement blocks are fixedly connected to the lower end face of the gantry 2. By setting up a guide frame 21, a slide bar 22, and displacement blocks, the gantry frame 2 can achieve horizontal displacement on the processing platform 1 by sliding the two displacement blocks on the slide bar 22.

[0024] The sidewalls of the two displacement blocks are slidably connected to the inner walls of the two guide frames 21, respectively. By making the sidewalls of the two displacement blocks slide and connect to the inner walls of the two guide frames 21 respectively, the sidewalls of the two displacement blocks can slide and move along the inner walls of the two guide frames 21 respectively.

[0025] The working principle of the above embodiment is as follows: In use, the safety helmet is placed on the pressure seat 20, and then the carbon fiber composite yarn is covered on the surface of the safety helmet. After the pressure ring 5 presses down to achieve the adhesion of the yarn to the surface of the safety helmet, the two No. 2 telescopic cylinders 23 can be activated to push the air blowing plate 17 downwards, so that the multiple hot air nozzles 19 on the inner wall of the air blowing plate 17 approach the yarn. Then, the hot air host 10 is activated so that its hot air passes through the hot air transmission pipe 11 and is guided into the air plate pipe by the adjustment component. The air plate pipe guides the hot air to the air inlet hole 18 of the air plate so that it fills the air cavity. The multiple hot air nozzles 19 can then spray the hot air in the air cavity outward to heat the yarn. The entire process only requires manual placement of the yarn on the surface of the safety helmet. The subsequent pressing and heating and adhesion of the yarn can be completed automatically. The degree of intelligence is high and the processing efficiency is effectively improved.

[0026] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
