During the process of laying carbon fiber, the fiber bundle 11 needs to be heated by the heating device 15, so that the external driving device drives the mounting frame 12 to move and lays the fiber bundle 11 on the surface of the object to be laid 1 through the pressing roller 14, and then the fiber bundle 11 is shaped by the extrusion of the pressing roller 14;

[0028] The limiting mechanism includes a limiting plate 2, which is movably connected to the surface of the pressure roller 14. A movable groove 21 is opened inside the pressure roller 14, and a sliding groove 22 is opened on the surface of the movable groove 21. A supporting spring 23 is fixedly connected to the surface of the movable groove 21. The surface of the limiting plate 2 is fixedly connected to a limiting block 24. Under the action of the limiting plate 2, the fiber bundle 11 will not melt and escape to both sides after being heated by the heating device 15, so that the fiber bundle 11 will form strips on the object 1 to be laid.

[0029] Furthermore, two groups of limit plates 2 and movable grooves 21 are provided, the two groups of limit plates 2 are provided on both sides of the pressure roller 14, the two groups of movable grooves 21 are opened on both sides of the pressure roller 14, the limit plates 2 are movably connected to the surface of the movable grooves 21, and two groups of slide grooves 22 are provided, the two groups of slide grooves 22 are opened on both sides of the movable grooves 21. Under the connection between the limit plates 2 and the movable grooves 21, when the limit plates 2 come into contact with the fiber material 1 to be laid, they will move into the movable grooves 21 and will not hinder the laying of the fiber bundles 11.

Under the connection between the limit block 24 and the slide groove 22, the limit plate 2 is limited so that it will not move out of the movable groove 21. At the same time, under the connection of the support spring 23, a supporting force is applied to the limit plate 2, so that the limit plate 2 protrudes outside the pressure roller 14.

[0031] Furthermore, a pressing mechanism is provided on the surface of the mounting frame 12, and the pressing mechanism includes an auxiliary roller 3, the auxiliary roller 3 is press-connected to the surface of the fiber bundle 11, a first connecting rod 31 is installed on the surface of the auxiliary roller 3, a partition 32 and a baffle 33 are fixedly connected to the surface of the first connecting rod 31, a plug-in tube 34, a sleeve 35 and a connecting spring 36 are fixedly connected to the surface of the baffle 33, and a second connecting rod 37 is fixedly connected to the surface of the mounting frame 12. Under the action of the auxiliary roller 3, the pressing roller 14 can press the same fiber bundle 11 for a second time after pressing the fiber bundle 11, thereby realizing the extrusion and shaping of the fiber bundle 11.

[0032] Furthermore, the auxiliary roller 3 is rotatably connected to the surface of the first connecting rod 31. The cross-section of the first connecting rod 31 is "U"-shaped. Two groups of partitions 32 are provided. The two groups of partitions 32 are arranged on both sides of the auxiliary roller 3. The diameter of the partition 32 is larger than the inner diameter of the auxiliary roller 3. Two groups of baffles 33 are provided. The auxiliary roller 3 can be limited by the partition 32 so that it can rotate between the two groups of partitions 32, thereby preventing the auxiliary roller 3 from moving freely on the first connecting rod 31 when the device is moved.

[0033] Furthermore, the number of each group of baffles 33 is two, one group of baffles 33 is fixedly connected to the surface of the first connecting rod 31, and the other group of baffles 33 is fixedly connected to the surface of the second connecting rod 37. The plug-in tube 34 is slidably connected to the inner surface of the sleeve 35, and both ends of the connecting spring 36 are fixedly connected to the surface of the baffle 33. The group of baffles 33 installed on the first connecting rod 31 is fixed at both ends of the first connecting rod 31, and the group of baffles 33 installed on the second connecting rod 37 are respectively fixed on the two groups of second connecting rods 37. The installation of the connecting spring 36 can be achieved through the baffle 33, and then the first connecting rod 31 and the second connecting rod 37 are connected. Under the connection of the plug-in tube 34 and the sleeve 35, the connecting spring 36 is limited to avoid bending of the connecting spring 36 during the pressing process of the auxiliary roller 3, so that the first connecting rod 31 moves along the direction of the plug-in tube 34.

[0034] Furthermore, two groups of second connecting rods 37 are provided, and the two groups of second connecting rods 37 are arranged on both sides of the mounting frame 12. One end of the second connecting rod 37 is fixedly connected to the surface of the mounting frame 12, and the other end of the second connecting rod 37 is fixedly connected to the surface of the baffle 33. The two groups of second connecting rods 37 are connected to realize the installation of the auxiliary roller 3 on the mounting frame 12.

[0035] Working principle: When the device moves, it drives the pressure roller 14 to rotate, and the fiber bundle 11 is limited by the limit plates 2 on both sides after being heated by the heating device 15. When the limit plate 2 rotates to the surface of the object to be laid 1, the limit plate 2 is squeezed by the object to be laid 1 and slides into the movable groove 21, and drives the limit block 24 to slide on the surface of the slide groove 22. At this time, the support spring 23 is in a compressed state. When the limit plate 2 leaves the object to be laid 1, the limit plate 2 moves out of the pressure roller 14 under the action of the supporting force exerted by the support spring 23, and limits the limit plate 2 by the limit block 24.

[0036] During the movement of the shaping device, the second connecting rod 37 and the first connecting rod 31 are driven to move by the movement of the mounting frame 12, so that the auxiliary roller 3 is pressed against the surface of the fiber bundle 11 and rotates between the two sets of partitions 32. During the extrusion process, the insertion tube 34 slides along the inner surface of the sleeve 35, and then the connecting spring 36 is in a compressed state and exerts a supporting force on the baffle 33, so that the auxiliary roller 3 further extrude and shape the fiber bundle 11.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
