Abstract
Description
Technical Field
[0001] This application belongs to the field of paper feeding technology, specifically a paper feeding device for paper product processing. Background Technology
[0002] Paper products are various products made from paper and paperboard as raw materials through a series of processing techniques such as cutting, printing, folding, binding, and coating. They are widely used in packaging, cultural products, and household paper, playing an important role in daily life and industrial production. The paper product processing process involves multiple steps from raw paper to finished product. Each step requires the paper to enter the corresponding equipment in the appropriate state, speed, and position. The paper feeding equipment is the key equipment to ensure that the paper can enter each processing stage smoothly, stably, and accurately. Whether it is the need for the paper to pass through the printing cylinder flat and at a uniform speed during printing, the requirement for accurate paper positioning during cutting, or operations such as folding and binding, all rely on the paper feeding equipment to deliver the paper to the required position according to the process requirements. Therefore, the paper feeding equipment is indispensable in the paper product processing flow.
[0003] For example, the utility model patent with announcement number CN222960845U discloses a conveying device for paper product processing, which belongs to the field of conveying devices. It includes a conveyor frame and a stacking frame. The inner side of the conveyor frame is equipped with a conveyor belt. Through the set guide and tidying structure, it plays a limiting and guiding role for the cardboard, ensuring the neatness of the cardboard after stacking and achieving the effect of subsequent processing. A limiting component is installed at the end of the stacking frame. The cloth belt set between the two fixed frames limits and blocks the cardboard, which can prevent the cardboard from moving and falling off, and protect the integrity of the cardboard. One end of the cloth belt is connected to the rotating shaft through a cloth roll and is used in conjunction with the pressing end cap. The tension of the cloth belt can be adjusted according to the actual situation.
[0004] However, in actual use, it was found that the device achieves limiting by setting multiple guide plates in the limiting mechanism. Due to the large differences in size and shape of different paper products, the position of the guide plates needs to be frequently adjusted to adapt to the stacking requirements of different paper products. However, too many guide plates make the adjustment process cumbersome and complicated. The operator needs to adjust the rotation angle of each guide plate one by one, which not only consumes a lot of time and effort but also reduces production efficiency. Therefore, a paper feeding device for paper product processing is provided. Utility Model Content
[0005] The purpose of this application is to provide a paper feeding device for paper product processing in order to solve the problems mentioned above.
[0006] The technical solution adopted in this application is as follows: A paper feeding device for paper product processing includes a conveyor belt support. Two fixed support plates are symmetrically fixedly installed on the left and right sides of the conveyor belt support, and inclined stacking paper is fixedly installed on the side of the two fixed support plates that are close to each other. A paper feeding mechanism is provided on the bottom surface of the inclined stacking paper. An installation plate is fixedly installed on one side of the fixed support plate above the inclined stacking paper. Two adjusting sleeves are movably sleeved on the outer surface of the installation plate, and a side limiting plate is fixedly installed on one side of each of the two adjusting sleeves. A bidirectional screw is threadedly connected to one side of the side limiting plate. The right end of the bidirectional screw extends to the outside of the fixed support plate. A rotating head is fixedly installed at one end of the bidirectional screw that extends to the outside of the fixed support plate. Two bearing seats are fixedly installed near the middle of the front side of the installation plate, and one end of the bidirectional screw passes through the middle of the bearing seat.
[0007] In a preferred embodiment, the paper feeding mechanism includes a rotating shaft, a rotating roller, a friction paper feeding belt, and a rectangular through hole. One side of the fixed support plate is rotatably connected to two rotating shafts located below the inclined stacking board, and rotating rollers are fixedly installed on the outer surfaces of both rotating shafts. The friction paper feeding belt is movably sleeved on the outer surface of the rotating rollers. A rectangular through hole corresponding to the friction paper feeding belt is opened on the top surface of the inclined stacking board. The top outer surface of the friction paper feeding belt is located inside the rectangular through hole. A drive mechanism connected to the rotating shaft is provided on the side of the conveyor belt bracket.
[0008] In a preferred embodiment, a limiting connecting block is slidably connected to the top surface of the inclined stacking paper near the center.
[0009] In a preferred embodiment, one side of the inclined stacking plate is rotatably connected to an auxiliary roller above the conveyor belt support, and two baffle plates are fixedly installed on the front side of the mounting plate.
[0010] In a preferred embodiment, a conveyor belt is provided inside the conveyor belt support, and a support column is fixedly installed on the bottom surface of the conveyor belt support.
[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:
[0012] 1. In this application, due to the adoption of the above-mentioned solution, the operator starts the drive mechanism connected to the rotating shaft. The drive mechanism drives the rotating shaft to rotate, which in turn drives the rotating roller to rotate. The friction feed belt sleeved on the rotating roller then rotates, using friction to smoothly feed the paper on the inclined stack of paperboard through the rectangular through hole and transport it to the conveyor belt inside the conveyor belt support. During the paper transport process, the auxiliary roller assists in the paper transition and guidance, preventing the paper from bending or jamming. At the same time, the side limiting plates on the mounting plates on both sides can be adjusted according to the paper width by rotating the rotating head to drive the bidirectional screw to rotate, adjusting the sliding sleeve to slide along the mounting plate, thereby adjusting the position of the side limiting plates to limit the paper laterally. This ensures that the paper is stably transported along the center line of the conveyor belt to the subsequent paper product processing station, improving the paper limiting efficiency and increasing convenience.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0019] refer to Figures 1-4As shown, a paper feeding device for paper product processing includes a conveyor belt support 1. A conveyor belt is installed inside the conveyor belt support 1, and a support column 14 is fixedly installed on the bottom surface of the conveyor belt support 1. The conveyor belt support 1 provides a stable support frame for the entire paper feeding device. The conveyor belt inside is the core carrier for paper feeding, which can continuously and stably transport paper. The support column 14 enhances the overall stability of the device, effectively disperses the pressure generated during the operation of the device, prevents the device from shaking or shifting, ensures a smooth and reliable paper feeding process, and facilitates the installation and ground fixing of the device.
[0020] refer to Figures 1-4 As shown, two fixed support plates 2 are symmetrically fixedly installed on the left and right sides of the conveyor belt support 1, and inclined stacking plate 3 is fixedly installed on the side of the two fixed support plates 2 that is close to each other. A paper feeding mechanism 4 is provided on the bottom surface of the inclined stacking plate 3, and a limit connecting block 11 is slidably connected to the top surface of the inclined stacking plate 3 near the middle. An auxiliary roller 12 is rotatably connected to one side of the fixed support plate 2 above the conveyor belt support 1. Two baffle plates 13 are fixedly installed on the front side of the mounting plate 5. The fixed support plates 2 provide the mounting foundation for the inclined stacking plate 3, the paper feeding mechanism 4 and other components, ensuring the accurate position of each component. The inclined stacking plate 3 is used to... The inclined design conforms to the natural stacking and sliding characteristics of paper, facilitating paper storage and utilizing gravity to assist in paper feeding, thereby improving feeding efficiency. The paper feeding mechanism 4 facilitates paper transport and driving. The limiting connecting block 11 can adjust the position according to the paper specifications to limit the stacked paper and prevent it from shifting or scattering. The auxiliary roller 12 assists in paper transition and guidance, preventing paper from bending or jamming during transport. The baffle plate 13 prevents the paper from shifting to the sides during transport, ensuring that the paper is transported along the predetermined path and improving feeding accuracy.
[0021] refer to Figures 1-4As shown, the paper feeding mechanism 4 includes a rotating shaft 401, a rotating roller 402, a friction paper feeding belt 403, and a rectangular through hole 404. Two rotating shafts 401 are rotatably connected to one side of the fixed support plate 2, located below the inclined stacking plate 3. Rotating rollers 402 are fixedly mounted on the outer surfaces of both rotating shafts 401. The friction paper feeding belt 403 is movably sleeved on the outer surface of the rotating rollers 402. A rectangular through hole 404 corresponding to the friction paper feeding belt 403 is opened on the top surface of the inclined stacking plate 3. The top outer surface of the friction paper feeding belt 403 is located inside the rectangular through hole 404. A drive mechanism connected to the rotating shaft 401 is provided on the side of the conveyor belt bracket 1. Through the provided drive mechanism... The rotating shaft 401 is designed to rotate, which in turn causes the rotating roller 402 to rotate. Through the friction between the friction feed belt 403 and the paper, the paper on the inclined stacking board 3 is smoothly and continuously transported to the subsequent work station. The drive mechanism consists of a motor, a synchronous pulley, and a synchronous belt. The design of the rectangular through hole 404 allows the friction feed belt 403 to make close contact with the paper, ensuring the effective transmission of paper feeding power. Compared with traditional roller paper feeding, the friction feed belt 403 has better friction adjustment and adaptability. The friction can be adjusted according to different paper materials and thicknesses to avoid paper damage due to excessive friction or slippage due to insufficient friction, effectively improving the stability and reliability of paper feeding.
[0022] refer to Figures 1-4 As shown, a mounting plate 5 is fixedly installed on one side of the fixed support plate 2 above the inclined stacking plate 3. Two adjusting sleeves 6 are movably fitted on the outer surface of the mounting plate 5, and side limiting plates 7 are fixedly installed on one side of each of the two adjusting sleeves 6. A double-acting screw 8 is threadedly connected to one side of the side limiting plate 7. The right end of the double-acting screw 8 extends to the outside of the fixed support plate 2, and a rotating head 9 is fixedly installed at the end of the double-acting screw 8 that extends to the outside of the fixed support plate 2. Two bearing seats 10 are fixedly installed near the middle of the front side of the mounting plate 5, and one end of the double-acting screw 8 passes through the middle of the bearing seat 10. By rotating the rotating head 9, the screw can be driven... When the bidirectional lead screw 8 rotates, the adjusting sleeve 6 can slide along the mounting plate 5 under the action of the threaded transmission, thereby conveniently and quickly adjusting the position of the side limiting plate 7. The side limiting plate 7 can limit the paper laterally to prevent the paper from deviating during the conveying process and ensure the positional accuracy of the paper on the conveyor belt. The bearing seat 10 provides stable support and rotation conditions for the bidirectional lead screw 8, reducing friction and shaking when the lead screw rotates, ensuring the smoothness and accuracy of the adjustment process of the side limiting plate 7, so that the equipment can quickly adapt to paper of different widths and improve the versatility and flexibility of the equipment.
[0023] The implementation principle of the paper feeding device for paper product processing according to this application is as follows: First, the user places the paper to be fed onto the inclined stacking board 3. Then, the user adjusts its position using the sliding limit connecting block 11 to initially limit the paper and prevent it from shifting. Next, the user starts the drive mechanism connected to the rotating shaft 401. The drive mechanism drives the rotating shaft 401 to rotate, which in turn drives the rotating roller 402 to rotate. The friction feeding belt 403, sleeved on the rotating roller 402, rotates accordingly, using friction to smoothly feed the paper from the inclined stacking board 3 through the rectangular through-hole 404 onto the conveyor belt inside the conveyor belt support 1. During the paper feeding process... During the process, the auxiliary rollers 12 assist in the transition and guidance of the paper, preventing the paper from bending or jamming. At the same time, the side limiting plates 7 on the two mounting plates 5 can be adjusted according to the width of the paper by rotating the rotating head 9 to drive the bidirectional lead screw 8 to rotate, and adjusting the sliding sleeve 6 to slide along the mounting plate 5, thereby adjusting the position of the side limiting plates 7 to limit the paper laterally and ensure that the paper is stably transported along the center line of the conveyor belt to the subsequent paper product processing station. The device can improve the limiting efficiency of the paper by synchronously adjusting the paper feeding mechanism 4 and the two side limiting plates 7. The whole process realizes the automated operation of paper from stacking, conveying to limiting, effectively improving the paper feeding efficiency and accuracy of paper product processing.
