Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a high-efficiency constant tension feeding device. Background Technology

[0002] Due to the large diameter and low density of carbon fiber bundles, carbon fiber cloth is relatively loose overall. It deforms locally under tension, is heavy, and wide widths tend to sink in the middle, forming a concave arc. It is also difficult to straighten laterally. The edges of carbon fiber cloth are generally sewn with yarn, leaving a certain length to prevent the fiber bundles from unraveling laterally. During the winding process, the carbon fiber cloth roll has a certain random width range on the left and right sides, which can lead to a slight lateral offset during feeding. Because the carbon fiber bundles are loosely bonded laterally, and each bundle contains hundreds or thousands of fine filaments longitudinally, the compression in the thickness direction is large. This results in the cloth being wound under certain deformation during traction, making it prone to sinking during feeding. Utility Model Content

Therefore, they have no substantial technical significance.

[0033] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0034] Please see Figures 1-6 This utility model provides a high-efficiency constant tension feeding device, including a support frame 1; a feeding unit, which is mounted on the support frame 1 and includes a feeding mounting frame 2, a feeding mounting assembly, and a feeding shaft 3. The feeding shaft 3 is rotatably mounted on the feeding mounting frame 2 via the feeding mounting assembly and is used to place the fabric roll; a conveying unit, which is mounted on the support frame 1 and conveys and leads out the fabric piece from the feeding unit; and a control unit, which includes a correction control mechanism, a tension control mechanism, and a controller. The correction control mechanism and the tension control mechanism cooperate with the feeding unit. The correction control mechanism adjusts the position of the fabric roll, the tension control mechanism adjusts the tension of the fabric roll, and the controller controls the correction control mechanism and the tension control mechanism.

[0035] This invention provides a high-efficiency constant-tension feeding device for conveying and feeding carbon fiber rolls. The feeding unit of this invention has a rotatable feeding shaft 3 for holding the roll. The fabric piece released from the roll is led out through the conveying unit to feed external materials. The control unit includes a deviation control mechanism and a tension control mechanism. The deviation control mechanism can sense the position of the carbon fiber fabric piece during transmission and adjust it in real time to ensure the correct position of the carbon fiber fabric piece during continuous feeding. The tension control mechanism can sense and adjust the tension of the transmitted roll in real time to maintain a constant tension transmission. This solves the problem of tension changes caused by torque variations due to the reduction in diameter of the carbon fiber roll during transmission, resulting in more stable overall conveying and feeding. Optionally, the controller is an existing technology device; a PLC controller or other controllers that meet the requirements can be used, which will not be discussed further here.

[0036] In this embodiment, please refer to Figure 1 and Figure 2 The feeding installation assembly includes two feeding support groups, which are respectively engaged with both ends of the feeding shaft 3. Each feeding support group includes a feeding support 4 and a feeding shaft 3 sleeve. The feeding support 4 is mounted on the feeding installation frame 2, and the feeding shaft 3 is rotatably mounted on the feeding support 4 through the feeding shaft 3 sleeve.

[0037] Optionally, the feeding shaft 3 assembly may be equipped with rotating mounting parts such as bearings for cooperating with the feeding shaft 3, and the feeding support assembly may also be equipped with hand-tightening screws for fixed installation.

Each of the material transfer rollers 7 is installed at intervals on the material transfer mounting frame 6, and the material transfer rollers 7 are staggered in height position.

[0039] Multiple sets of conveyor rollers 7 are arranged at intervals and staggered in spatial height. When the fabric passes through each set of conveyor rollers 7, it will be supported in sections. Therefore, by arranging multiple sets of compact conveyor rollers, the concave arc surface caused by the carbon cloth sagging during the feeding process can be effectively prevented.

[0040] In this embodiment, please refer to Figure 1 , Figure 3 and Figure 4The correction control mechanism includes a correction sensor 8 and a correction adjustment assembly. The correction sensor 8 is mounted on the support frame 1 via a correction mounting bracket, and is located at the edge of the fabric workpiece. The correction sensor 8 is electrically connected to the correction adjustment assembly via the controller. The correction adjustment assembly includes a correction drive 9, a correction slider 10, and a correction slide rail 11. The correction slide rail 11 is mounted on the support frame 1, and its arrangement direction is the same as that of the feeding shaft 3. The feeding mounting frame 2 is disposed on the correction slider 10, and the correction drive 9 drives the feeding mounting frame 2 to move and adjust on the correction slide rail 11. The correction drive 9 is a drive electric cylinder, and the bottom of the feeding mounting frame 2 is provided with a correction push plate 12. The output end of the drive electric cylinder cooperates with the correction push plate 12.

[0041] The web-aligning sensor 8 is located at the edge of the fabric piece. It uses ultrasonic waves to sense the offset range of the fabric piece during transmission in real time and feeds the measured data back to the controller. The controller then controls the web-aligning transmission component to move and adjust the unloading mounting frame 2, thereby achieving web-aligning adjustment during transmission and controlling the offset. The application of the web-aligning sensor 8 is existing technology and will not be described in detail here.

[0042] In this embodiment, please refer to Figure 2 The feeding mounting assembly also includes an auxiliary discharge roller 13, which is rotatably mounted on the feeding mounting frame 2 via an auxiliary bearing seat 14, and the auxiliary discharge roller 13 and the feeding shaft 3 are offset in the height direction.

[0043] The auxiliary discharge roller 13 is provided to help guide the fabric roll on the feeding shaft 3 to be output into the material transfer unit. The height of the auxiliary discharge roller is offset from that of the feeding shaft 3 in the height direction, so that the output fabric roll has an initial tension, which facilitates the subsequent tension detection and control mechanism. Optionally, the height of the auxiliary discharge roller 13 is higher than that of the feeding shaft 3.

[0044] In this embodiment, please refer to Figure 2 , Figures 4-6The tension control mechanism includes a tension sensor 15 and a tension adjustment structure 16; the tension sensor 15 cooperates with the auxiliary bearing seat 14, the tension adjustment mechanism cooperates with the feeding shaft 3, and the tension sensor 15 is electrically connected to the tension adjustment structure 16 through the controller. The tension adjustment structure 16 includes a tension mounting assembly, a magnetic powder damper 19, a tension adjustment coupling 21, and a tension adjustment gear set. The tension mounting assembly includes a tension mounting base plate 17 and a tension adjustment shaft seat 18. The tension mounting base plate 17 is mounted on the feeding mounting frame 2, and the tension adjustment shaft seat 18 is mounted on the tension mounting base plate 17.

The tension adjustment gear set includes a first tension adjustment gear 22, a second tension adjustment gear 23, and a third tension adjustment gear 24. The first tension adjustment gear 22 is mounted on the tension adjustment coupling 21, the second tension adjustment gear 23 is mounted on the feeding shaft 3, and the third tension adjustment gear 24 is engaged between the first tension adjustment gear 22 and the second tension adjustment gear 23. The tension adjustment structure 16 also includes multiple protective covers 25.

[0045] In the tension control mechanism, a tension sensor 15 senses the tension during fabric transmission. The tension sensor 15 feeds back the measured data to the controller, which compares the measured value with the set value. When a deviation exists, the controller adjusts the damping of the magnetic powder damper 19. The tension adjustment coupling 21 and the feeding shaft 3 are connected by a tension adjustment gear set, thus allowing the magnetic powder damper 19 to change the rotational damping of the feeding shaft 3, thereby achieving constant tension control and making the overall transmission and feeding more stable. Both the tension sensor 15 and the magnetic powder damper 19 are existing technologies and will not be described in detail here.

[0046] In summary, this invention provides a highly efficient constant tension feeding device for the transmission and feeding of carbon fiber rolls. The feeding unit of this invention has a rotatable feeding shaft for placing the roll. The fabric piece released from the roll is led out through the transmission unit to supply material to the outside. The control unit includes a deviation control mechanism and a tension control mechanism. The deviation control mechanism can sense the position of the carbon fiber fabric piece during transmission and adjust it in real time to ensure the correct position of the carbon fiber fabric piece during continuous feeding. The tension control mechanism can sense and adjust the tension of the transmitted roll in real time to maintain a constant tension transmission. This solves the problem of tension changes caused by torque variations due to the reduction in diameter of the carbon fiber roll during transmission, resulting in more stable overall transmission and feeding.
