Description

Technical Field

[0001] This utility model relates to the field of paper feeding device technology, and in particular to an automatic paper feeding device. Background Technology

[0002] In the modern papermaking industry and related paper processing fields, automation, efficiency, and precision in production processes are key elements for enhancing enterprise competitiveness and production benefits. The paper feeding stage, as a crucial transitional phase connecting pulping with subsequent cutting and finishing processes, directly impacts the overall production line's capacity and product quality through its stability and efficiency. Therefore, developing an automated, high-precision, and stable paper feeding device has become a critical issue urgently needing to be addressed within the industry.

[0003] Currently, most companies use a semi-automatic, mechanically assisted paper feeding method in their paper feeding operations. In this method, workers manually place the pulp board at a specific starting position, and then rely on a simple mechanical transmission device, such as a standard belt conveyor, to slowly transport the pulp board to the cutting area. When cutting the pulp board, a simple fixed cutter is typically used, with a robotic arm or similar device manually controlled to press down and cut. Furthermore, the adsorption and fixation of the pulp board mostly employs simple pneumatic adsorption methods, lacking precise adjustment and control mechanisms.

[0004] However, this traditional semi-automatic paper feeding method has many drawbacks. Due to the large number of manual steps involved, the paper feeding efficiency is greatly limited by the speed and skill of the workers, making it difficult to meet the needs of large-scale, continuous production. Furthermore, when manually placing the pulp slab, it is difficult to ensure consistency in placement each time. Coupled with the limited precision of the simple mechanical transmission device, this results in poor paper feeding accuracy, frequently causing the pulp slab to shift or tilt during transport. This, in turn, affects the accuracy of subsequent paper cutting processes, leading to large errors in paper cutting dimensions and high scrap rates, severely restricting the improvement of production efficiency and product quality. Therefore, an automatic paper feeding device is proposed to solve these problems. Utility Model Content

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-4An embodiment of this utility model provides an automatic paper feeding device, including a frame 1. A transmission component is provided on the side wall of the frame 1 to achieve stable transmission of the pulp board and ensure that the pulp board can be accurately delivered to the subsequent paper cutter. A paper cutting component is provided on the side wall of the frame 1 to accurately cut the pulp board and ensure that the cut size of the pulp board meets the requirements of subsequent processing. A sliding component is provided on the side wall of the frame 1 to drive the entire device into or out of the paper cutting range to achieve precise coordination between the device and the paper cutting process. A vacuum extraction component is provided on the side wall of the frame 1 to generate negative pressure to adsorb the pulp board during the pulp board transmission process and prevent the pulp board from shifting during transmission.

[0031] The transmission assembly includes a cavity 2, a transmission belt 3, a transfer roller 4, and a motor 5. The sidewall of the cavity 2 is bolted to the top of the frame 1. The cavity 2 not only serves as the mounting carrier for the transfer roller 4 but also works with the vacuum extraction assembly to create a negative pressure space, providing conditions for the adsorption of the slurry plate. The transmission belt 3 is made of polyurethane with anti-slip textured surfaces. The transmission belt 3 is fitted onto the sidewall of the transfer roller 4 to directly support and transport the slurry plate. The sidewall of the transfer roller 4 is rotatably connected to the inside of the cavity 2 via a deep groove ball bearing to support the transmission belt 3 and drive its operation. The motor 5 is a 130ST-M06025 servo motor. The wall is fixedly connected to the side wall of the cavity 2 by the motor bracket. The output end of the motor 5 is fixedly connected to the side wall of the transfer roller 4 on one side by the coupling to provide power for the rotation of the transfer roller 4. The cavity 2 is located below the transmission belt 3. The cavity 2 has holes at both ends and the top. The transmission belt 3 has holes all around. These holes, together with the vacuum extraction component, allow the negative pressure in the cavity 2 to act smoothly on the surface of the transmission belt 3, thereby adsorbing the slurry plate. The transmission speed of the transmission belt 3 can be kept consistent with the running speed of the slurry plate through the speed adjustment function of the motor 5, so as to avoid the stretching or wrinkling of the slurry plate due to speed mismatch during the transmission process, thus achieving the effect of stable transmission of the slurry plate.

The output end of the cylinder 10 is fixedly connected to the connecting block 11 via a thread. The side wall of the connecting block 11 is rotatably connected to the side wall of the paper cutter 9 via a pin. When the cylinder 10 is working, its output end pushes the connecting block 11 to move. The connecting block 11 drives the paper cutter 9 to rotate around the pin inside the cutter holder 8. The paper cutter 9 cooperates with the bottom blade 7 to perform the cutting motion, achieving the effect of precise cutting of the pulp board.

[0033] The sliding assembly includes a mounting bracket 12, a second cylinder 13, a bearing housing 14, a sliding rod 15, and a linear bearing 16. The mounting bracket 12 is made of aluminum alloy and its sidewall is bolted to the top of the frame 1. It is used to mount the second cylinder 13 and the bearing housing 14. The second cylinder 13 is a standard SC80×100 cylinder. Its sidewall is fixed to the sidewall of the mounting bracket 12 via a cylinder bracket. The output end of the second cylinder 13 is fixed to the sidewall of the cavity 2 via a floating joint, providing power for the sliding of the device. The bearing housing 14 is made of cast iron, and its sidewall is bolted to... A fixed connection is attached to the upper surface of the mounting bracket 12 for mounting a linear bearing 16. The linear bearing 16 is a linear ball bearing. The side wall of the linear bearing 16 is fixedly connected to the inside of the bearing seat 14 by an interference fit. The side wall of the sliding rod 15 is slidably connected to the inside of the linear bearing 16. One end of the sliding rod 15 is fixedly connected to the side wall of the cavity 2 by a thread. When the cylinder 2 13 is working, its output end pushes or pulls the cavity 2. The cavity 2 drives the sliding rod 15 to slide back and forth inside the linear bearing 16. The sliding rod 15 and the linear bearing 16 cooperate to perform guided sliding motion, achieving the effect of the device accurately entering or exiting the paper cutting range.

[0034] The vacuum extraction assembly includes a connector 17, a steel wire hose 18, and a clamp 19. The connector 17 is made of brass and has good sealing properties. The side wall of the connector 17 is fixedly connected to the side wall of the cavity 2 by threads, and is used to connect the steel wire hose 18 to the cavity 2. The clamp 19 is made of stainless steel and its side wall is fixedly connected to the side wall of the connector 17 by bolts, and is used to fix the steel wire hose 18 to prevent it from shifting during operation. The steel wire hose 18 is a corrugated hose made of 304 stainless steel, which has the characteristics of corrosion resistance and good flexibility. One end of the steel wire hose 18 is fixed by the clamp 19 and connected to the connector 17. The other end of the steel wire hose 18 is connected to a vacuum pump, model 2XZ-4, which provides power for vacuum extraction. The steel wire hose 18 is fixed by the clamp 19 and connected to the cavity 2 to create a negative pressure inside the cavity 2, thereby adsorbing the slurry plate and preventing the slurry plate from shifting during the conveying process, thus achieving the effect of stable slurry plate conveying.

[0035] Working principle: When this automatic paper feeding device is working, the sliding assembly is first activated. The output end of cylinder 2 13 pushes the cavity 2, and with the cooperation of the sliding rod 15 and the linear bearing 16, the entire device is driven into the paper cutting range. At the same time, the vacuum extraction assembly starts to operate. The steel wire hose 18 is connected to the cavity 2 through the connecting seat 17, so that a negative pressure is formed inside the cavity 2 by the steel wire hose 18 fixed by the pipe clamp 19. Then, the motor 5 starts, and its output end drives the transfer roller 4 to rotate, which in turn causes the transmission belt 3 wound on the transfer roller 4 to run, and the transmission speed of the transmission belt 3 can be kept consistent with the speed of the pulp board.

[0036] After the pulp board produced by the paper output section is cut to a width of 200mm by the water jet, it falls between the bottom knife 7 and the paper cutter 9 in the paper cutting assembly. At this time, the output end of cylinder 10 pushes the paper cutter 9 to rotate around the paper cutter seat 8 through the connecting block 11, cooperating with the bottom knife 7 fixed on the base 6 to cut the pulp board. The upper part of the pulp board after being cut will slide into the transmission belt 3 along the bottom knife 7. Due to the openings at both ends and the top of the cavity 2 and the openings around the transmission belt 3, the negative pressure inside the cavity 2 will create a suction force on the surface of the transmission belt 3, thereby adsorbing the pulp board. The pulp board is then conveyed to the paper cutter on the opposite side by the transmission belt 3.

[0037] During the conveying process, the water jets in the paper output section work, gradually cutting the pulp sheet from 200mm to a wider width, forming an inclined surface on the pulp sheet. The portion of the pulp sheet that enters the paper cutter along with the paper feeding device also becomes wider until the entire pulp sheet is completely in the paper cutter. Afterward, the output end of cylinder 13 of the sliding component retracts, driving the device to slide along the sliding rod 15 and exit the paper cutting range; the vacuum extraction component stops operating, the negative pressure in the cavity 2 disappears; the motor 5 stops working, the transmission belt 3 stops running, and the entire paper feeding process is completed.
