Description

Technical Field

[0001] This utility model relates to the field of paper product manufacturing technology, and in particular to a paper stacking and unloading mechanism with automatic counting and alignment functions. Background Technology

[0002] In industries such as printing and packaging, paper handling is a very basic and important task. In the production process of these industries, large quantities of paper often need to be stacked and cut for subsequent processing, such as printing, cutting, and binding. For example, in book printing, paper needs to be stacked in a certain quantity and then bound into books. In the packaging industry, cut paper needs to be stacked neatly for making packaging boxes.

[0003] A search revealed Chinese Patent Publication No. CN214086980U, which discloses an automatic cardboard unloading mechanism. The mechanism includes a conveyor table for transporting cardboard, comprising a support and a second conveyor line rotatably connected to the support. The unloading mechanism also includes a collection frame for stacking cardboard and a lifting frame for driving the collection frame and the second conveyor line to rise and fall. The lifting frame is equipped with sprocket lifting groups respectively connected to the second conveyor line and the collection frame, allowing the second conveyor line and the collection frame to rise synchronously with the height of the cardboard. The collection frame is equipped with two slidable guides for restricting the movement of the cardboard. This automatic cardboard unloading mechanism can automatically transport and stack printed cardboard, thus greatly saving manpower. The guides sliding on the frame restrict the movement of the cardboard, limiting the movement of cardboard of different sizes and ensuring neat stacking.

[0004] In this technology, the automatic paperboard feeding mechanism can automatically transport and stack the printed paperboard, thus greatly saving manpower. However, in the paper stacking operation, manual counting and sorting of paper are still required. Manual counting and sorting of paper require dedicated staff to work continuously, which undoubtedly increases the number of workers and significantly raises the company's labor costs. Therefore, a paper stacking and feeding mechanism with automatic counting and alignment functions is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a paper stacking and unloading mechanism with automatic counting and alignment functions, aiming to improve the problem that the existing technology still requires people to count and separate the paper, which increases the number of workers and labor costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a paper stacking and unloading mechanism with automatic counting and alignment functions, comprising a base, a support frame fixedly connected to the top of the base, a measuring mechanism provided on the top of the support frame, a transmission mechanism provided on the inner wall of the support frame, and a transport mechanism provided on the outer side of the support frame. The measuring mechanism includes a support frame, which is slidably connected to the top of the support frame. A connecting frame is fixedly connected to the inner wall of the support frame. Two fixed plates are fixedly connected to the bottom of the support frame. A sensor is fixedly connected to the bottom of the connecting frame. A lifting component for real-time blocking is slidably connected inside the connecting frame. A rotating shaft is fixedly connected to the adjacent side of the two fixed plates. Multiple fixed rings are fixedly connected to the outer side of the rotating shaft. Multiple pressure belts are fixedly connected to the outer side of each fixed ring. Through the above technical solution: the support frame is located at the top of the support frame, and there is a sensor at the bottom of the connecting frame on its inner wall. The sensor contains a lifting component that can block in real time. There are multiple fixing rings outside the rotating shaft between the two fixed plates at the bottom of the support frame, and multiple pressure bands outside each fixing ring. When the paper is stacked and unloaded, the lifting component of the sensor can block in real time to perform related operations. At the same time, the fixing rings and pressure bands on the rotating shaft can play a certain role in fixing and straightening the paper.

[0007] As a further description of the above technical solution: The transmission mechanism includes a fixed frame, both sides of which are fixedly connected to the inner wall of the support frame. Multiple drive devices are fixedly connected to the outside of the fixed frame. The output ends of the multiple drive devices are fixedly connected to a transmission belt. The internal parts of the multiple transmission belts are rotatably connected to a concave-convex shaft. The above technical solution involves a fixed frame installed on the inner wall of the support frame. Multiple drive devices outside the fixed frame drive the transmission belt, and the concave and convex shafts inside the transmission belt assist in rotation, thereby achieving the transmission function.

[0008] As a further description of the above technical solution: Both ends of the concave and convex shafts are fixedly connected to connecting plates. The far sides of the two connecting plates are fixedly connected to the inner wall of the support frame, i.e., the side closest to the fixed frame. A feeding device is fixedly connected to the bottom of the connecting plates. The above technical solution involves connecting plates at both ends of the concave-convex shaft. One side of the connecting plate is connected to the inner wall of the support frame near the fixed frame. A feeding device is installed at the bottom of the connecting plate. During operation, the concave-convex shaft is installed on the support frame through the connecting plate, providing an installation foundation for the feeding device. The feeding device performs material conveying at the bottom of the connecting plate.

[0009] As a further description of the above technical solution: The external of the concave and convex shaft is slidably connected to multiple connecting belts, and each of the multiple connecting belts is rotatably connected to a fixed wheel, and each of the multiple fixed wheels is fixedly connected to a rotating shaft. The above technical solution involves multiple connecting belts on the outside of the convex-concave shaft, each connecting belt containing a fixed wheel, and each fixed wheel containing a rotating shaft. During operation, the convex-concave shaft drives the fixed wheel to rotate via the sliding connecting belts, thereby causing the rotating shaft inside the fixed wheel to rotate.

[0010] As a further description of the above technical solution: Both ends of the rotating shaft are rotatably connected to fixing members, and the opposite sides of the two fixing members are fixedly connected to the inner wall of the support frame, i.e., the side away from the connecting plate. With the above technical solution: the two ends of the rotating shaft are supported by fixing parts, which are fixed to the inner wall of the support frame on the side away from the connecting plate, and the rotating shaft can rotate between the fixing parts.

[0011] As a further description of the above technical solution: The transport mechanism includes a support base, the outside of which is slidably connected to the bottom of the inner wall of the support frame, and a conveyor belt is fixedly connected to the top of the support base; Through the above technical solution: the support base can slide at the bottom of the inner wall of the support frame, and the conveyor belt at the top of it is used for transportation. The sliding of the support base drives the conveyor belt to move, thereby realizing the transportation of goods.

[0012] As a further description of the above technical solution: The support base is fixedly connected to a plurality of slide rails, the slide rails are fixedly connected to the top outer wall of the support frame, a counterweight is slidably connected to the outer wall of the support frame, the top of the counterweight is fixedly connected to the slide rails, i.e. the end away from the support base, and a discharge roller is fixedly connected to the top of the base, i.e. the side close to the support base. The above technical solution involves: multiple sliding wheels on the outside of the support base, which are connected to the top outer wall of the support frame. A counterweight is slidably connected to the outer wall of the support frame, and the top of the counterweight is connected to the end of the sliding wheel away from the support base. A discharge roller is located on the top of the base near the support base. The support base can slide on the top of the support frame via the sliding wheels, and the counterweight can slide on the outer wall of the support frame and cooperate with the sliding wheels, affecting the movement of the support base. The discharge roller on the base can perform the discharge operation.

[0013] As a further description of the above technical solution: The lifting assembly includes a movable comb, the outer side of which is slidably connected to the inside of the connecting frame, and multiple protective pads are fixedly connected to the bottom of the movable comb. The above technical solution allows the movable comb to move freely. Multiple protective pads are located at the bottom of the movable comb, providing protection during operation.

[0014] This utility model has the following beneficial effects: In this invention, the fixed ring rotates with the rotating shaft, and the pressure belt connected to the outside of the fixed ring is also driven to make a circular motion around the rotating shaft. During the rotation, the pressure belt periodically taps the paper, further helping the paper to become neat and flat, so that the sensor can more accurately measure the height and quantity of the paper stack. This realizes the development of paper counting and sorting towards a higher level of automation and unmanned operation, significantly reducing the number of workers and effectively controlling labor costs.

[0015] In this invention, the coordinated operation of the various components of the transmission and transport mechanisms enables the paper to be processed efficiently and stably from automatic feeding and individual transport and measurement to final stacking and unloading. This achieves the integration of different equipment and technologies, resulting in new applications for specific production scenarios and bringing about new effects. Attached Figure Description

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.

Multiple connecting belts 507 are slidably connected to the outside of the concave-convex shaft 504. The connecting belts 507 are used for power transmission and receive the paper conveyed by the conveyor belt 503. Fixed wheels 508 are rotatably connected inside the multiple connecting belts 507. The fixed wheels 508 and the concave-convex shaft 504 support the connecting belts 507 so that they can transport the paper. Rotating shafts 509 are fixedly connected inside the multiple fixed wheels 508. Rotating shafts 509 are used for support and rotation. Fixing members 5010 are rotatably connected to both ends of the rotating shaft 509. Fixing members 5010 are used for fixing and support. The opposite sides of the two fixing members 5010 are fixedly connected to the inner wall of the support frame 2, i.e., the side away from the connecting plate 505. Specifically, the fixed frame 501 supports and fixes the drive device 502. The drive device 502 provides power to the transmission belt 503. The transmission belt 503 is in direct contact with the paper and drives the paper to move on the transmission mechanism 5 through friction. At the same time, the paper is conveyed and positioned under the action of the concave-convex shaft 504. The connecting plate 505 connects the concave-convex shaft 504 and the support frame 2, providing stable support for the concave-convex shaft 504 and ensuring that the concave-convex shaft 504 can rotate stably within the support frame 2. The concave-convex shaft 504 cooperates with the transmission belt 503 and provides support and transmission for the connecting belt 507. The connecting belt 507 transmits the rotation of the concave-convex shaft 504 to the fixed wheel 508 to realize the transmission of power, so that the fixed wheel 508 can drive the rotating shaft 509 to rotate.

[0021] Reference Figure 2 and Figure 6 The transport mechanism 6 includes a support base 601, which is externally slidably connected to the bottom of the inner wall of the support frame 2. The support base 601 is used for support and sliding. A conveyor belt 602 is fixedly connected to the top of the support base 601. The conveyor belt 602 transports the paper processed by the measuring mechanism 3 and the transmission mechanism 5 to a designated location, realizing the functions of paper stacking and unloading. Multiple slide rail wheels 603 are fixedly connected to the outside of the support base 601. The slide rail wheels 603 provide guidance and support for the sliding of the support base 601. The slide rail wheels 603 are externally fixedly connected to the top outer wall of the support frame 2. A counterweight 604 is slidably connected to the outer wall of the support frame 2. The counterweight 604 is used to increase the stability of the support base 601. The top of the counterweight 604 is fixedly connected to the slide rail wheel 603, i.e., the end away from the support base 601. A discharge roller 605 is fixedly connected to the top of the base 1, i.e., the side close to the support base 601. The discharge roller 605 is used for unloading and transporting. Specifically, the support base 601 supports the conveyor belt 602 and achieves horizontal position adjustment of the conveyor belt 602 through a sliding connection with the bottom of the inner wall of the support frame 2. The slide wheel 603 is installed on the outside of the support base 601 and cooperates with the slide rail on the top outer wall of the support frame 2 to provide guidance and support for the sliding of the support base 601, so that the support base 601 can slide smoothly in the support frame 2. The counterweight 604 is connected to the support base 601 through the slide wheel 603 to increase the stability of the support base 601 and prevent the support base 601 from shaking and displacing due to uneven force during paper transportation.

[0022] Working principle: The base 1 serves as the foundation of the overall mechanism, enabling it to operate stably in the workshop. The support frame 2 is fixed on top of the base 1, supporting the sliding of the support frame 301. The sensor 304 is connected to the support frame 301 through the connecting frame 302, allowing the sensor 304 to monitor the position, height, and quantity of the paper in real time. The support frame 301 is fixed to the support frame 301 through the fixing plate 303, causing the fixing ring 306 to drive the pressure belt 307 to rotate around the rotating shaft 305, tapping the paper to make it neat and flat, facilitating the sensor 304 to accurately measure the height and quantity of the paper stack. When the transport mechanism 6 is running, the movable comb 401 will follow, making the paper stack neat and flat. The protective pad 402 at its bottom prevents the movable comb 401 from having a hard collision with the top of the transport mechanism 6.

[0023] During operation, the fixed frame 501 supports the fixed drive device 502, which drives the transmission belt 503 to rotate. The transmission belt 503 drives the paper to move on the transmission mechanism 5 through friction. At the same time, the paper is conveyed and positioned by the concave and convex shaft 504. The connecting plate 505 ensures that the concave and convex shaft 504 can rotate stably within the support frame 2. While the concave and convex shaft 504 cooperates with the transmission belt 503, it provides support and transmission for the connecting belt 507. The connecting belt 507 transmits the rotation of the concave and convex shaft 504 to the fixed wheel 508 to realize the transmission of power. The fixed wheel 508 drives the rotating shaft 509 to rotate, and finally completes the paper transmission work on the transmission mechanism 5.

[0024] After the paper is conveyed to the top of the transport mechanism 6 via the conveying mechanism 5 and measured and stacked by the measuring mechanism 3, the support seat 601 slides at the bottom of the support frame 2, so that the conveyor belt 602 can be parallel to the discharge roller 605 in the horizontal direction. The slide wheel 603 and the counterweight 604 are connected to the support seat 601 through the support frame 2, making the support seat 601 more stable during operation and ensuring the smoothness of the paper transport process. After the conveyor belt 602 is parallel to the discharge roller 605, the conveyor belt 602 is started to transport the neatly stacked paper to the next stage.
