Description

Technical Field

[0001] This utility model relates to the field of carbon fiber prepreg production, specifically an improved yarn rack for producing carbon fiber prepreg. Background Technology

[0002] The yarn rack used in the production of carbon fiber prepreg is a core piece of equipment in the production process. It stably supports the yarn bobbin and precisely guides the carbon fiber filaments into subsequent processing. The yarn rack is compact, stable and adjustable, and can efficiently arrange the yarn bobbin in a limited space to ensure the continuous and stable extraction of carbon fiber filaments. By precisely controlling the rotation speed and tension, the yarn rack is crucial to the performance and quality of the prepreg.

[0003] According to the announcement number CN217756286U, "A yarn rack for carbon fiber prepreg fabric", it is described that by pulling the cap, the embedded rod can be moved, and the embedded rod can be moved out from the inside of the rotating support rod. The rotating support rod rotates 90 degrees inside the support frame. The yarn bobbin placement rod can be rotated to a vertical position, so that multiple used yarn bobbins fall down at the same time under the action of gravity, achieving batch processing, faster disassembly and separation speed, and improving the efficiency of yarn rack replacement of yarn bobbins.

[0004] However, during the unloading process, the yarn bobbins may be damaged as they fall directly into the receiving frame below. Furthermore, the fallen yarn bobbins are placed haphazardly, which reduces the ease of use of the yarn rack. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an improved yarn rack for the production of carbon fiber prepreg, so as to solve the technical problem that the yarn bobbin may be damaged if it falls into the receiving frame.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an improved yarn frame for producing carbon fiber prepreg fabric, comprising a yarn frame body, a plurality of rotating rollers rotatably connected to one side of the yarn frame body, a yarn bobbin placement rack on one side of the plurality of rotating rollers, an mounting rod on one side of the yarn frame body, a first motor on one side of the mounting rod, a drive wheel on the output end of the first motor, a belt fitted on the drive wheel and the plurality of rotating rollers, a discharge mechanism on one side of the belt, the discharge mechanism comprising a discharge plate, an extension plate on one side of the discharge plate, an electric push rod on one side of the extension plate, a limiting mechanism on one side of the plurality of yarn bobbin placement racks, the limiting mechanism comprising a movable rod, a second motor above the movable rod, a movable plate on the output end of the second motor, a plurality of limiting rods on one side of the movable plate, and a sliding mechanism below the movable rod.

[0007] By adopting the above technical solution, the operation of the lead screw motor is controlled by the control center. The output end of the lead screw motor drives the connecting block to slide smoothly in the guide groove. At the same time, based on the sliding out of the limit rod, the control center controls the operation of the electric push rod. The extension end of the electric push rod drives the extension plate and the unloading plate to move smoothly. During the movement, the unloading plate pushes the yarn bobbin on the yarn bobbin placement frame onto the limit rod.

[0008] Furthermore, both the unloading plate and the main body of the yarn frame are semi-circular ring structures, and the unloading plate is sleeved on multiple yarn bobbin placement frames.

[0009] By adopting the above technical solution, the unloading plate and the main body of the yarn frame with the semi-circular structure can evenly distribute the force and improve the load-bearing capacity of the entire yarn frame.

[0010] Furthermore, the multiple yarn bobbin placement racks and limiting rods are arranged in a corresponding manner and are arranged at the same center, and the limiting rods are inserted into the yarn bobbin placement racks through through grooves.

[0011] By adopting the above technical solution, the precise positioning of the yarn bobbin during the processing is ensured. The one-to-one correspondence of multiple yarn bobbin placement racks and limiting rods ensures that each yarn bobbin can be stably supported and limited.

[0012] Furthermore, a sliding mechanism is provided below the limiting mechanism. The sliding mechanism includes a mounting frame, a guide groove is provided in the mounting frame, and a connecting block is slidably connected inside the guide groove.

[0013] By adopting the above technical solution, the movement flexibility of the limiting mechanism is improved, and the sliding mechanism enables the limiting mechanism to slide smoothly along the guide groove.

[0014] Furthermore, a lead screw motor is provided on one side of the mounting frame, and a connecting block is threadedly connected to the output end of the lead screw motor. The connecting block is connected to the movable rod.

[0015] By adopting the above technical solution, the automatic control of the limit mechanism is realized. The introduction of the lead screw motor enables the limit mechanism to perform precise displacement control through the control center.

[0016] Furthermore, the first motor, the second motor, the electric actuator, and the lead screw motor are all electrically connected to an external power source through the control center.

[0017] By adopting the above technical solution, the full automation control of the yarn frame is realized. All key components are connected to an external power source through the control center, enabling the yarn frame to operate automatically according to a preset program.

[0018] Furthermore, a support frame is provided below the mounting rod, and a base plate is provided below the support frame.

[0019] By adopting the above technical solutions, the overall stability of the yarn frame is improved. The setting of the support frame and the base plate enables the yarn frame to be stably supported on the ground, avoiding displacement and deviation caused by vibration and shaking.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention, through the design of an unloading mechanism, a limiting mechanism, and a sliding mechanism, firstly achieves smooth sliding of the limiting mechanism by precisely controlling the operation of the lead screw motor through the control center. This allows the limiting rod to slide accurately out of the through groove of the yarn bobbin placement frame, facilitating subsequent yarn bobbin unloading operations. This not only improves the automation level of the unloading process but also ensures stable support of the yarn bobbin before unloading. Simultaneously, the introduction of the electric push rod allows the unloading plate to smoothly push the yarn bobbin from the yarn bobbin placement frame onto the limiting rod, preventing direct drops and collisions during unloading, thus effectively reducing damage to the yarn bobbin. Furthermore, the rotation of the movable plate driven by the second motor allows the yarn bobbin to be easily rotated to within reach, facilitating quick and accurate removal and neat placement of the yarn bobbin in the designated position. This not only improves the efficiency and accuracy of yarn bobbin unloading but also, through the precise coordination of the limiting and sliding mechanisms, achieves guiding, limiting, and orderly arrangement of the yarn bobbin, further enhancing the precision of yarn bobbin processing and the ease of use of the yarn frame.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] Example 1:

[0029] An improved yarn rack for producing carbon fiber prepreg, such as Figures 1-4 As shown, the device includes a yarn frame body 1. Multiple rotating rollers are rotatably connected to one side of the yarn frame body 1. A yarn bobbin placement rack 7 is located on one side of the multiple rotating rollers. A mounting rod 4 is located on one side of the yarn frame body 1. A first motor 3 is located on one side of the mounting rod 4. A drive wheel is located at the output end of the first motor 3. A belt 2 is fitted onto the drive wheel and the multiple rotating rollers. A discharge mechanism 8 is located on one side of the belt 2. The discharge mechanism 8 includes a discharge plate 801. An extension plate 803 is located on one side of the discharge plate 801. An electric push rod 802 is located on one side of the extension plate 803. A limit mechanism 9 is located on one side of the multiple yarn bobbin placement rack 7. The limit mechanism 9 includes a movable rod 901. A second motor 903 is located above the movable rod 901. The output end of the second motor 903 is... There is a movable plate 902, and multiple limiting rods 904 are set on one side of the movable plate 902. A sliding mechanism 10 is set below the movable rods 901. The operation of the lead screw motor 102 is controlled by the control center. The output end of the lead screw motor 102 drives the connecting block 104 to slide smoothly in the guide groove 103. At the same time, based on the sliding of the limiting rods 904, the control center controls the operation of the electric push rod 802. The telescopic end of the electric push rod 802 drives the extension plate 803 and the unloading plate 801 to move smoothly. During the movement, the unloading plate 801 pushes the yarn bobbin on the yarn bobbin placement frame 7 onto the limiting rods 904. This process avoids the yarn bobbin from falling directly and colliding with each other during the unloading process, thereby effectively reducing the damage to the yarn bobbin and improving the integrity rate of the yarn bobbin.

[0030] See Figure 1 , Figure 2 , Figure 3 The unloading plate 801 and the yarn frame body 1 are both semi-circular ring structures. The unloading plate 801 is sleeved on multiple yarn bobbin placement frames 7. The semi-circular ring structure of the unloading plate 801 and the yarn frame body 1 can evenly distribute the force, improving the load-bearing capacity of the entire yarn frame. At the same time, the unloading plate 801 sleeved on multiple yarn bobbin placement frames 7 makes the unloading process more stable and continuous, avoiding the jumping and collision of yarn bobbins during unloading, thereby effectively reducing damage to the yarn bobbins. In addition, this sleeved connection also facilitates the relative movement between the unloading plate 801 and the yarn bobbin placement frames 7, providing convenience for unloading the yarn bobbins and improving production efficiency.

[0031] See Figure 1 , Figure 2 , Figure 3, Figure 4 Multiple yarn bobbin holders 7 and limiting rods 904 are arranged in a one-to-one correspondence and are set at the same center. The limiting rods 904 are inserted into the yarn bobbin holders 7 through the through grooves 11, which ensures the precise positioning of the yarn bobbins during processing. The one-to-one correspondence between the multiple yarn bobbin holders 7 and the limiting rods 904 ensures that each yarn bobbin can be stably supported and limited. At the same time, the setting at the same center ensures the stability of the yarn bobbin and avoids vibration and noise caused by eccentricity. In addition, the insertion and insertion of the limiting rods 904 into the yarn bobbin holders 7 through the through grooves 11 makes it easy to insert and remove the limiting rods 904, which provides convenience for loading and unloading the yarn bobbins and also facilitates the maintenance and upkeep of the yarn holders.

[0032] Example 2:

[0033] See Figure 1 , Figure 2 , Figure 3 Below the limiting mechanism 9, a sliding mechanism 10 is provided. The sliding mechanism 10 includes a mounting frame 101, and a guide groove 103 is provided inside the mounting frame 101. A connecting block 104 is slidably connected inside the guide groove 103, which improves the movement flexibility of the limiting mechanism 9. The setting of the sliding mechanism 10 allows the limiting mechanism 9 to slide smoothly along the guide groove 103. At the same time, the sliding connection between the connecting block 104 and the guide groove 103 ensures the stability and accuracy of the limiting mechanism 9 during movement, avoiding deviations and shaking caused by movement. In addition, the sliding mechanism 10 also facilitates the position adjustment and maintenance of the limiting mechanism 9, improving the ease of use and reliability of the yarn frame.

[0034] See Figure 1 , Figure 2 , Figure 3 A lead screw motor 102 is provided on one side of the mounting frame 101. The output end of the lead screw motor 102 is threadedly connected to a connecting block 104. The connecting block 104 is connected to the movable rod 901, realizing the automated control of the limit mechanism 9. The introduction of the lead screw motor 102 enables the limit mechanism 9 to be precisely displaced through the control center. At the same time, the threaded connection between the lead screw motor 102 and the connecting block 104 ensures the accuracy and stability of the displacement, avoiding displacement deviation caused by transmission error. In addition, the connection between the connecting block 104 and the movable rod 901 enables the limit mechanism 9 to move with the movement of the connecting block 104, realizing remote control and automated operation of the limit mechanism 9.

[0035] See Figure 1 , Figure 2 , Figure 3The first motor 3, the second motor 903, the electric actuator 802, and the lead screw motor 102 are all electrically connected to an external power source through the control center, realizing the full automation control of the yarn frame. All key components are connected to an external power source through the control center, enabling the yarn frame to operate automatically according to a preset program. At the same time, it also facilitates remote monitoring and fault diagnosis of the yarn frame, improving the operating efficiency and reliability of the yarn frame.

[0036] See Figure 1 , Figure 2 , Figure 3 A support frame 5 is installed below the mounting rod 4, and a base plate 6 is installed below the support frame 5, which improves the overall stability of the yarn frame. The support frame 5 and the base plate 6 enable the yarn frame to be stably supported on the ground, avoiding displacement and deviation caused by vibration and shaking. At the same time, the support frame 5 and the base plate 6 also play a role in distributing the force, so that the yarn frame can maintain the integrity and stability of the structure when subjected to a large load.

[0037] The implementation principle of this utility model is as follows: When it is necessary to unload the processed yarn bobbin, the control center first controls the screw motor 102 to run, so that the output end of the screw motor 102 drives the connecting block 104 to slide in the guide groove 103. The connecting block 104 drives the limiting mechanism 9 to slide, so that the limiting rod 904 slowly slides out of the through groove 11 on the yarn bobbin placement frame 7. At this time, the electric push rod 802 is controlled to run, so that the telescopic end of the electric push rod 802 drives the extension plate 803 and the unloading plate 801 to move in the direction of the limiting mechanism 9. During the movement, the yarn bobbin on the yarn bobbin placement frame 7 will be pushed onto the limiting rod 904. When the yarn bobbin is completely transferred to the limiting rod 904, the second motor 903 is then controlled to run, causing the output end of the second motor 903 to drive the movable plate 902 to rotate. When the upper limiting rod 904 of the movable plate 902 rotates to within reach, the yarn bobbin is quickly removed and placed properly. During this operation, the limiting rod 904 is sleeved inside the yarn bobbin placement frame 7, thereby guiding and limiting the yarn bobbin, improving the precision of the yarn bobbin processing. Furthermore, the presence of the limiting mechanism and the sliding mechanism 10 prevents the yarn bobbin from falling directly into the receiving frame and causing damage, and also improves the neatness of the yarn bobbin placement, thus improving the ease of use of the yarn rack.
