Description

Technical Field

[0001] This utility model relates to the field of paper roll production technology, and more specifically, it relates to a paper feeding device for continuous carbon paper production. Background Technology

[0002] In the field of continuous carbon paper production, the stability and accuracy of the paper feeding device directly affect production efficiency and product quality. Traditional paper feeding devices mostly adopt a fixed support structure, which cannot flexibly adjust the paper feeding height according to production needs. When changing paper tubes, operators need to use external tools for cumbersome height adjustment, which not only reduces production efficiency but also poses safety hazards. Moreover, existing devices lack effective paper tube fixing and rely solely on simple mechanical clamping methods, which are prone to relative slippage during high-speed operation, making it difficult to guarantee the accuracy of the paper feeding position. At the same time, existing paper feeding devices lack tension monitoring and feedback mechanisms, and tension fluctuations generated during the paper feeding process cannot be adjusted in time. When the production line speed changes, tension instability occurs, which can cause the paper to break due to being too tight or stack too loosely.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] In one possible embodiment, please refer to Figure 1 and Figure 2As shown, a paper feeding device for continuous carbon paper production includes a support platform 1, a first support frame 2 fixedly connected to the support platform 1, a limit seat 3 slidably connected inside the first support frame 2, a drive motor 5 fixedly connected to the limit seat 3, the output end of the drive motor 5 passing through the first support frame 2 and fixedly connected to an air shaft 6 for driving the paper tube to rotate, and a drive device 4 for driving the limit seat 3 to slide inside the first support frame 2. The drive device 4 drives the limit seat 3 to slide up and down. The drive device 4 includes a telescopic reducer 401 fixedly connected inside the first support frame 2. The output end of 401 is fixedly connected to the bottom of the limiting seat 3. The first support frame 2 is provided with a first sliding groove 201 that slides and engages with the output end of the drive motor 5. The worm gear transmission mechanism inside the telescopic reducer 401 can convert the rotational motion of the motor into linear motion, thereby realizing the telescopic motion of the output end of the telescopic reducer 401, and thus realizing the vertical lifting and lowering of the limiting seat 3. By setting the air shaft 6 to slide and engage with the first support frame 2 and driving it through the drive device 4, it is convenient for the staff to adjust the height of the air shaft 6, making the replacement of the paper tube simpler and more convenient.

[0022] For further details, please refer to Figure 1 , Figure 2 and Figure 3As shown, a clamping device 7 is provided on one side of the air shaft 6, which rotates and engages with the air shaft 6. The clamping device 7 is used to abut against the paper tube and can ensure high stability during the paper feeding process. The clamping device 7 includes a sliding plate 701 fixedly connected to one side of the limiting seat 3. A second sliding groove 202 is provided on the first support frame 2, which slides and engages with the sliding plate 701. A shock-absorbing bracket 702 is fixedly connected to the sliding plate 701. The shock-absorbing bracket 702 is L-shaped and made of shock-absorbing material, which has good elasticity and absorption performance. It can be rubber, polyurethane, etc. One end of the shock-absorbing bracket 702 rotates and engages with the air shaft 6. A limiting guide block 703 is slidably connected to the shock-absorbing bracket 702. During the rotation of the air shaft 6, the vibration of the drive motor 5 and the air shaft 6 will be controlled by the limiting guide block. Block 703 transmits the data to the shock-absorbing bracket 702, which effectively absorbs the data through its internal elastic element. The sliding cooperation between the limiting guide block 703 and the shock-absorbing bracket 702 limits the radial movement of the paper tube, ensuring the stable operation of the paper feeding device and effectively guaranteeing the accuracy of the paper feeding position. When the paper tube needs to be installed, the limiting guide block 703 can slide out of the shock-absorbing bracket 702. After the paper tube is installed, the limiting guide block 703 is slid back into the shock-absorbing bracket 702. A circular frame 704 is fixedly connected to the end of the limiting guide block 703 away from the shock-absorbing bracket 702. The circular frame 704 is sleeved on the outside of the air shaft 6, and a rotating bearing 705 that rotates with the air shaft 6 is fixedly connected to the circular frame 704. The paper tube is reliably fixed by the air expansion of the air shaft 6 and the tight cooperation between the air shaft 6 and the rotating bearing 705.

[0023] For further details, please refer to Figure 1 , Figure 4 and Figure 5 As shown, a second support frame 8 is fixedly connected to one side of the first support frame 2, and a tension monitoring device 9 is slidably connected to the second support frame 8. The tension monitoring device 9 can monitor the accuracy of tension data and ensure the stability of paper tension. The tension monitoring device 9 includes a lead screw motor 901 set inside the second support frame 8, and a transmission lead screw 902 is fixedly connected to the output end of the lead screw motor 901. A limit block 903 is slidably connected to the second support frame 8, and the limit block 903 is threadedly connected to the transmission lead screw 902. The rotation of the lead screw 902 can drive the limit block 903 to slide up and down. The second support frame 8 is provided with a third slide groove 801. The limit block 903 is fixedly connected with a fixed frame 904 that slides with the third slide groove 801. The fixed frame 904 is C-shaped. A rotating roller 905 is rotatably connected inside the fixed frame 904. Touch-sensitive blocks 906 are slidably connected to both ends of the fixed frame 904. The rotating roller 905 is rotatably connected between the two touch-sensitive blocks 906. A damper 907 is supported and connected between the touch-sensitive blocks 906 and the fixed frame 904.

[0024] For details, please refer to Figure 1 , Figure 4 and Figure 5 As shown, the rotating frame not only rotates with the fixed frame 904 but also slides with it. Changes in paper tension act on the rotating roller 905, causing it to slide on the fixed frame 904, i.e., along the direction of the damper 907. The sliding of the rotating roller is transmitted to the touch-sensitive block 906, causing it to generate a displacement signal. The damper 907 can absorb the tension changes in a timely manner and keep the rotating roller 905 in its original position, thereby ensuring the accuracy of the tension monitoring data and the stability of the paper tension.

[0025] For further details, please refer to Figure 1 As shown, the support platform 1 is fixedly connected to the third support frame 10 on the side of the first support frame 2 away from the second support frame 8. The third support frame 10 is fixedly connected to the support shaft 11. Multiple infrared displacement sensors 12 are arranged at equal intervals on the support shaft 11. By setting the infrared displacement sensors 12, the infrared displacement sensors 12 monitor the change in the height of the carbon paper in real time through the non-contact ranging principle and feed the signal back to the control system. The control system controls the telescopic reducer 401 to work and adjust the height of the air shaft 6, thereby achieving precise control of the paper feeding position.
