[0025] Embodiment 1 like Figure 1-Figure 7 As shown, the front yarn box device proposed in the embodiment of the present invention includes: A box body 1, wherein the interior of the box body 1 is hollow and is used to store the prepreg tow roll body, and the box body 1 has an opening; A connecting portion 2 is detachably connected to the opening and seals the interior of the box body 1; At least one material roll taking-up and untaking assembly 3 is arranged on the box body 1, and the material roll taking-up and untaking assembly 3 is used to unwind the tow on the prepreg tow material roll body arranged on the material roll taking-up and untaking assembly 3, and recycle the lining paper; A steering assembly 4 is arranged on the box body 1; A first re-conveying assembly 5 is provided on the box body 1 and is located below the steering assembly 4, and the steering assembly 4 is used to guide the tow separated from the prepreg tow roll body to the first re-conveying assembly 5; The first re-feeding assembly 5 is used to transport the filament bundle separated from the prepreg bundle roll body to the fiber placement head.

[0026] Specifically, the interior of the box 1 is used to store the prepreg tow roll body, which is a key material for laying in the automatic fiber laying machine. It is mainly wound with a composite material formed by pre-impregnation of carbon fiber or other high-performance fibers with resin. When the device needs to work, the technician can place the prepreg tow roll body stored in the box 1 through the opening of the box 1 and place it on the roll reel assembly 3. The connecting part 2 is detachably connected to the opening and seals the interior of the box 1. The number of roll reel assemblies 3 can be determined according to actual needs, and this application does not limit it.

[0027] Each material roll taking-up and releasing assembly 3 comprises a material roll taking-up and releasing part, a liner paper recovery part and a dancing wheel part; The material roll taking-up and unwinding part includes a driving component, a bearing component and a limiting component, wherein the driving component includes a driving motor, the driving motor is arranged on the box body 1, the driving motor has a driving shaft, the bearing component includes a bearing shaft, the bearing shaft is transmission-connected with the driving shaft and is used to penetrate into and carry the prepreg bundle material roll body, the limiting component includes a first limiting member and a second limiting member, the first limiting member is arranged at one end of the bearing shaft close to the driving shaft, the top surface of the first limiting member protrudes from the outer wall of the bearing shaft and is used to abut against the inner wall of the bundle roll, the second limiting member is arranged at one end of the bearing shaft away from the driving component, the second limiting member has an elastic limiting portion, the top surface of the elastic limiting portion protrudes from the outer wall of the bearing shaft and is used to abut against the end of the prepreg bundle material roll body.

[0028] The bearing shaft is passed through the roll of the prepreg bundle material roll body to hold the prepreg bundle material roll body. The driving motor is arranged on the box body 1. The driving motor drives the bearing shaft to rotate through its driving shaft to realize the transmission connection with the prepreg bundle material roll body, thereby accurately controlling the discharge speed and the belt tension, ensuring a constant laying tension and a stable discharge speed, and improving the quality and performance of the product. In addition, the design of the bearing shaft can adapt to prepreg bundle material roll bodies of different sizes, ensuring the versatility and flexibility of the equipment. In addition, after the top surface of the first limiting member abuts against the prepreg bundle material roll body, it can prevent the prepreg bundle material roll body from sliding or shifting on the bearing shaft, ensuring its position is fixed. The elastic limiting portion of the second limiting member abuts against the end of the prepreg bundle material roll body to prevent the prepreg bundle material roll body from loosening or shifting during the discharge process. When removing the prepreg bundle material roll body, the elastic limiting part can be pressed to shrink its top surface to be flush with the surface of the load-bearing shaft, and then the prepreg bundle material roll body can be pulled out along the axial direction of the load-bearing shaft to remove the prepreg bundle material roll body. Similarly, when installing the prepreg bundle material roll body, the inner tube of the prepreg bundle material roll body can be aligned with the load-bearing shaft and pushed in along the axial direction of the load-bearing shaft, so that the inner wall of the prepreg bundle material roll body compresses the elastic limiting part, so that the prepreg bundle material roll body can be loaded onto the load-bearing shaft. When the prepreg bundle material roll body is installed in place, the end of the prepreg bundle material roll body is separated from the top surface of the elastic limiting part, and the elastic limiting part recovers its deformation under the action of elasticity and abuts against the end face of the prepreg bundle material roll body to achieve the limitation of the prepreg bundle material roll body. The disassembly and assembly operation is simple and time-saving, which can reduce the production downtime during the replacement process, thereby improving production efficiency.

[0029] The lining paper recovery part includes a driving assembly, a guiding assembly, a bearing assembly and a locking assembly. The driving assembly includes a driving member and a rotating shaft. One end of the driving member is connected to the box body 1, and the rotating shaft is transmission-connected to the driving shaft of the driving member. The guiding assembly includes a connecting member and a rotating member. The connecting member is connected to the driving member. The rotating member is arranged outside the rotating shaft and rotates with the rotating shaft. The rotating member is rotationally connected to the connecting member. A limiting portion is arranged on the rotating member. The bearing assembly includes a lining paper roll for winding lining paper. An empty groove extending in the axial direction is formed on the surface of the lining paper roll. The lining paper roll is sleeved outside the rotating shaft. A positioning portion is provided at one end of the lining paper roll, which is matched with the limiting portion to make the lining paper roll rotate with the rotating shaft. The locking assembly is detachably arranged at one end of the rotating shaft away from the guiding assembly, and cooperates with the connecting end to clamp the bearing assembly.

[0030] The driving member is arranged on the box body 1, the rotating shaft is connected to the driving member, the rotating member is connected to the driving member through the connecting member, so that the relative position of the connecting member and the driving member is kept fixed, the lining paper roll is sleeved on the rotating shaft and is connected to the rotating member. Under this structure, the lining paper roll follows the driving member to realize rotation, and the cooperation of the positioning part and the limiting part can ensure the connection structure between the lining paper roll and the rotating member, so as to avoid the lining paper roll from moving or the rotating shaft from being unable to drive due to being too heavy. When using the lining paper winding device, firstly, one end of the lining paper is attached to the surface of the lining paper roll, and the locking assembly is installed to The end of the rotating shaft is used to clamp the liner paper roll, and then the driving member is controlled to drive the liner paper roll to rotate to reel in the liner paper. After reeling in, the locking assembly is removed from the rotating shaft, and the liner paper roll is pulled out from the rotating shaft. Since the surface of the liner paper roll is provided with an empty groove extending along the axial direction, the liner paper roll can be compressed by squeezing the liner paper wound outside the liner paper roll, so that the outer wall of the liner paper roll squeezes the empty groove, and the outer diameter of the liner paper roll becomes smaller under squeezing, so that the liner paper roll can be taken out from the liner paper rolled into a roll. The disassembly is very simple and labor-saving, thereby improving the efficiency of liner paper recovery and avoiding damage to the liner paper.

[0031] The dancing wheel part is an existing technology and can be obtained through purchase. The dancing wheel part, the lining paper recovery part and the material roll taking-up and releasing part cooperate with each other to guide the tow of the prepreg tow material roll body to the steering assembly 4.

[0032] The steering assembly 4 includes a mounting frame and at least one balance wheel assembly, the balance wheel assembly is rotatably mounted on the mounting frame, the mounting frame is mounted on, the balance wheel assembly includes a tow steering frame and at least one roller rotatably mounted on the tow steering frame, the tow steering frame includes two opposing and spaced baffle walls, which are respectively a first baffle wall and a second baffle wall, a rotating shaft may be provided at the center of the roller, and the wheel surface of the roller rotates around the rotating shaft at the center, the roller is rotatably connected between the first baffle wall and the second baffle wall through its rotating shaft, and the opposite ends of the rotating shaft are rotatably connected to The first baffle wall and the second baffle wall are on the roller, and there is a spacing between the two relative wheel surfaces, so that the shaft sleeves of the two wheel surface rotating shafts form an annular groove surrounding the circumference of the rotating shaft, and the annular groove forms a yarn bundle steering channel, so that the yarn bundle is introduced from one end side (the yarn bundle introduction side) of the annular groove, bypasses the annular groove and is led out from the other end side (the yarn bundle outlet side). Specifically, the yarn bundle can be released from the material roll taking-up and unwinding part, and the yarn bundle introduction side of the annular groove of the balance wheel assembly can be arranged close to the material roll taking-up and unwinding part, and the yarn bundle outlet of the yarn bundle steering device corresponds to the first heavy delivery component 5.

[0033] The steering device provided in this embodiment adopts a balance wheel assembly rotatably connected to the mounting frame, so that the balance wheel assembly can rotate flexibly and has multiple rotation angles, so that the yarn bundle introduction side of the annular groove position of the balance wheel assembly can flexibly adapt to the yarn bundle release from different angles of the material roll take-up and release part, and flexibly adapt to different feeding angles of the yarn bundle, instead of the material roll take-up and release part looking for a fixed yarn bundle introduction slot, thereby effectively avoiding the problems of yarn bundle flipping, deviation, and knotting, improving the stability and accuracy of yarn bundle transmission, reducing maintenance costs and enhancing adaptability. In addition, the yarn bundle is introduced into the annular groove of the flexibly swinging balance wheel assembly. After being placed in the groove, the yarn bundle is limited by the two relative wheel surfaces of the annular groove, which effectively limits the transportation path of the yarn bundle, so that the yarn bundle can always remain in the predetermined position during the transportation process; at the same time, due to the flexible swing of the balance wheel assembly, it will not give the yarn bundle excessive resistance while limiting the position, and will not damage the yarn bundle while playing a limiting role, further avoiding the problems of yarn bundle deviation, friction damage, flipping, and falling off, effectively improving the transportation accuracy of the yarn bundle, ensuring the stability of the yarn bundle during high-speed transportation, reducing wear, enhancing adaptability, reducing maintenance costs, and thereby improving the quality of the final product.
