[0002] As the education industry's demand for the number and types of test papers continues to increase, automated bundling machines can flexibly respond to the production and processing of large quantities of test papers and meet rapidly changing market demands. The development and application of automated test paper bundling machines represents the education industry's progress in intelligence and automation, promotes the research and development and application of related technologies, and promotes the modernization of the industry. Automated equipment can achieve standardized bundling processes, ensure consistent bundling quality for each test paper, and avoid quality differences caused by manual operation. Automated equipment can reduce errors caused by human factors, ensure the accuracy of test paper bundling, and improve overall work efficiency and the reliability of results.

[0003] When bundling test papers, the existing automatic test paper bundling machine needs to put the test papers into a packing box, and then bundle the packing box. During the bundling process, the test papers need to be manually put into the bundling machine one by one to achieve one-way bundling, and then the test papers are rotated to bundle again to achieve cross bundling, which increases labor costs and work intensity. Especially when facing a large number of test papers, the efficiency is low. In addition, the operation of rotating the test papers for cross bundling may increase the complexity and failure rate of the equipment. The operator needs to have certain skills and experience. Due to the need to manually put in the test papers and perform multiple bundling, the overall bundling speed is limited and cannot meet the peak demand. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide an automatic test paper bundling machine.

[0005] The technical solution adopted to solve the above technical problems is: an automatic test paper bundling machine, including a turning platform, a through hole is opened on one side of the top surface of the turning platform, and a hydraulic press is installed on the other side of the top surface of the turning platform, a push plate is fixedly connected to the output end of the hydraulic press, and a limit plate is fixedly connected to the bottom surface of the turning platform, and the limit plate is located at the through hole of the turning platform. Transport bundling mechanisms are arranged on both sides of the turning platform, and the two transport bundling mechanisms are arranged at an angle of ninety degrees.

[0006] Through the above technical solution, automated operation reduces dependence on manual labor, reduces labor costs and training costs, and reduces errors caused by human operation.

[0007] Furthermore, a fixed seat is fixedly connected to one side of the steering platform, and a hydraulic rod is rotatably connected to the other end of the fixed seat. The telescopic end of the hydraulic rod is rotatably connected to a first connecting plate, and the other end of the first connecting plate is fixedly connected to a rotating cylinder. The rotating cylinder is rotatably connected to a limit plate through a through end, and a rotating plate is fixedly connected to the through end of the rotating cylinder, and a plurality of rolling balls are rollingly connected to the top surface of the rotating plate, and the rolling balls are parallel to the steering platform.

[0008] Through the above technical solution, multi-directional bundling can be achieved to ensure the stability of the test papers during transportation and storage, reduce the risk of damage, reduce repetitive and labor-intensive work, improve employee job satisfaction and safety, and make more effective use of packaging space, facilitate storage and transportation, and improve logistics efficiency.

[0009] Furthermore, the transport bundling mechanism includes a transport frame, a ring plate is fixedly connected to the middle of the transport frame, a plurality of rollers are arranged on both sides of the ring plate, a sprocket is fixedly connected through the roller, both ends of the roller are rotatably connected to the transport frame, and chains are transmission-connected between the plurality of sprockets on both sides.

[0010] Furthermore, two second motors are installed on one side of the transport frame, the output end of the second motor is rotatably connected to the transport frame, and the two through ends of the second motor are respectively fixedly connected to a roller shaft on both sides of the annular plate.

[0011] Through the above technical solution, the packaging space can be used more compactly, the efficiency of transportation and storage can be improved, and the logistics cost can be saved. At the same time, the operation process is more concise and intuitive, which reduces the difficulty of operation and facilitates training and use.

[0012] Furthermore, one side of the annular plate is rotatably connected to a plurality of limiting wheels, and the limiting wheels are symmetrically distributed in a circle, an inner gear ring is slidably connected between the limiting wheels, and the limiting wheels limit the inner gear ring, one side of the inner gear ring is provided with a notch, a convex plate is welded on the top of the annular plate, a bundling rod is fixedly connected to the side of the inner gear ring away from the convex plate, and the bundling rod is located on the side away from the limiting wheel.

[0013] Through the above technical solution, space can be effectively utilized, making the bundling and transportation process more flexible, adapting to different production line layouts, conveniently connecting with other equipment, improving the compatibility of the overall system, and making switching between different transportation paths more convenient, simplifying the operation process, and at the same time, helping to maintain stability during transportation and reduce the risk of sliding or tilting of the packaging box.

[0016] The beneficial effects of the present invention are as follows: (1) The present invention adopts two transport and bundling mechanisms. The second motor drives one of the rollers in the transport frame to rotate. Under the joint action of the sprocket and the chain, several rollers rotate at the same time to move the packing box forward. When entering the annular plate, the first motor drives one of the gears to rotate, and then drives the inner gear ring to make a circular motion in the limiting wheel. The other gear follows and rotates synchronously. At the same time, the limiting wheel rotates. After the inner gear ring rotates one circle, the strapping belt on the strapping rod is entangled with the packing box, so that the packing box is bundled. The cross-bundling process of the test paper can be realized, which can better fix the test paper and prevent it from being loose or deformed during transportation or storage, thereby ensuring the integrity of the test paper, reducing the steps of one-way bundling and rotating the test paper, improving the overall work efficiency, and saving time.

[0017] (2) The present invention moves the packing box onto the rotating plate, and the hydraulic rod moves the first connecting plate to rotate. The hydraulic rod rotates relative to the fixed seat and the first connecting plate, thereby driving the rotating drum to rotate, causing the rotating plate to rotate ninety degrees. Then the hydraulic device operates, causing the push plate to push the packing box on the rotating plate. Under the action of the rolling ball, the push plate slides to the transport and bundling mechanism on the other side, thereby longitudinally bundling the packing box. Cross bundling can be completed quickly, reducing time consumption during the operation process, improving overall work efficiency, and adapting to peak demand. At the same time, the need for manual operation is reduced, reducing labor costs, and improving work safety and comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] like Figure 1-Figure 4The test paper automatic bundling machine of this embodiment includes a steering platform 1, a through hole is formed on one side of the top surface of the steering platform 1, and a hydraulic device 2 is installed on the other side of the top surface of the steering platform 1. The hydraulic system can provide strong power, quickly complete the rotation and pushing actions, significantly improve the bundling speed, and is suitable for large-scale processing. The design of the hydraulic rod 5 and the first connecting plate 6 makes the movement in the bundling process more precise, reduces errors, and ensures that the packing box can be accurately positioned. A fixed seat 4 is fixedly connected to one side of the steering platform 1, and the other end of the fixed seat 4 is rotatably connected to the hydraulic rod 5. Automated operation reduces dependence on manual labor, reduces labor costs and training costs, and reduces errors caused by human operation. In addition, it can quickly complete the bundling work and significantly reduce processing time, especially when facing a large number of test papers. It can significantly improve the overall work efficiency. The telescopic end of the hydraulic rod 5 is rotatably connected to the first connecting plate 6. The structural design of the rotating drum 10 and the first connecting plate 6 provides good stability, ensuring that the packing box will not be displaced during the bundling process, thereby improving the bundling quality. The first connecting plate 6 is fixedly connected with a rotating drum 10 at the other end, and the rotating drum 10 is rotatably connected with the limiting plate 9 through the through end of the rotating drum 10. A rotating plate 11 is fixedly connected to the top surface of the rotating plate 11 with a plurality of rolling balls 12. The design of the rolling balls 12 can reduce friction and wear when the packing box slides, thereby extending the service life of the equipment and materials. The automated and efficient design reduces the intensity of manual operation and improves the safety and comfort of the working environment. The rolling balls 12 are parallel to the steering platform 1, and a push plate 3 is fixedly connected to the output end of the hydraulic press 2. The limiting plate 9 is fixedly connected to the bottom surface of the steering platform 1. The overall structure is relatively simple and stable, with a low failure rate and relatively low maintenance cost, ensuring the continuous and efficient operation of the equipment. The limiting plate 9 is located at the through hole of the steering platform 1, which can realize multi-directional bundling, ensure the stability of the test paper during transportation and storage, reduce the risk of damage, reduce repetitive and labor-intensive work, improve the work satisfaction and safety of employees, and more effectively utilize the packaging space, facilitate storage and transportation, and improve logistics efficiency.

[0025] The two sides of the steering platform 1 are provided with transport and bundling mechanisms 7, and the two transport and bundling mechanisms 7 are arranged at an angle of ninety degrees. The transport and bundling mechanisms 7 include a transport frame 71, and two second motors 72 are installed on one side of the transport frame 71. The output end of the second motor 72 is rotatably connected with the transport frame 71, and the through ends of the two second motors 72 are respectively fixedly connected to a roller shaft 73 on both sides of the annular plate 76, which can make more compact use of the packaging space, improve the efficiency of transportation and storage, and save logistics costs. At the same time, the operation process is more concise and intuitive, which reduces the difficulty of operation and is convenient for training and use. The middle part of the transport frame 71 is fixedly connected with an annular plate 76, and one side of the annular plate 76 is rotatably connected with a plurality of limiting wheels 77, and the plurality of limiting wheels 77 are symmetrically distributed on the circumference, and the plurality of limiting wheels 77 are arranged. An inner gear ring 78 is slidably connected between the positioning wheels 77, and the limiting wheel 77 limits the inner gear ring 78. One side of the inner gear ring 78 is notched. A convex plate 710 is welded on the top of the annular plate 76. One side of the convex plate 710 is rotatably connected to two gears 79. The two gears 79 are respectively connected to the inner gear ring 78 for transmission. A second connecting plate 711 is rotatably connected between the two gears 79. The middle part of the second connecting plate 711 is fixedly connected to the convex plate 710, which reduces the frequency of manually putting test papers into the packing box, reduces labor costs and operational difficulty, and at the same time, increases the sealing effect of the test papers, reduces the influence of the external environment on the test papers, such as dust, moisture, etc., and improves the preservation quality of the test papers. A first motor 8 is installed on the other side of the convex plate 710. The output end of the first motor 8 is connected to the convex plate 7 10 is rotatably connected through it, and the through end of the first motor 8 is fixedly connected to one of the gears 79, and a bundling rod 712 is fixedly connected to the side of the inner gear ring 78 away from the convex plate 710. The circular motion of the bundling rod 712 can apply pressure evenly to ensure that the bundling belt tightly wraps the test paper and enhances the stability of the bundling. The circular motion can quickly complete the bundling process, reduce the operation time, and improve the overall work efficiency. It is especially suitable for processing a large number of test papers. In addition, compared with the linear motion, the circular motion can reduce the wear of the bundling belt during bundling, extend the service life of the bundling material, and can adapt to test papers of different sizes and thicknesses, enhance the flexibility of the equipment, and be suitable for a variety of packaging needs. When the bundling rod 712 rotates following the inner gear ring 78, and the inner gear ring 78 is When rotating, the limiting wheel 77 at the bottom of the inner gear ring 78 can support the inner gear ring 78, so that the inner gear ring 78 is always in the limiting wheel 77 when rotating, and will not fall. The strapping rod 712 does not contact the limiting wheel 77, and there will be no motion interference. The strapping rod 712 is located on the side away from the limiting wheel 77. The use of a circular motion strapping method makes the automated operation smoother, reduces dependence on manual labor, improves the safety and efficiency of the operation, ensures the neatness of the strapping, makes the final packaging effect more beautiful, and improves the market image of the product. At the same time, it can better utilize the space of the packaging box and reduce the space required for transportation and storage. A number of roller shafts 73 are provided on both sides of the annular plate 76, and the roller shaft 73 is fixedly connected with a sprocket wheel 74.The two ends of the roller shaft 73 are rotatably connected to the transport frame 71, and a chain 75 is transmission-connected between a plurality of sprocket wheels 74 on both sides.

[0026] The working principle of this embodiment is as follows: before bundling, the bundling belt is installed on the bundling rod 712, and then the whole equipment is started, and the test paper and the packing box are placed on the transport bundling mechanism 7 on one side of the turning platform 1. The second motor 72 drives one of the rollers 73 in the transport frame 71 to rotate. Under the joint action of the sprocket 74 and the chain 75, several rollers 73 rotate at the same time, and the packing box is moved forward. When it enters the annular plate 76, the first motor 8 drives one of the gears 79 to rotate, and then drives the inner gear ring 78 to make a circular motion in the limiting wheel 77, and the other gear 79 follows the synchronous rotation. At the same time, the limiting wheel 77 rotates, and after the inner gear ring 78 rotates one circle, the bundling belt on the bundling rod 712 is entangled with the packing box, so that the packing box is transversely bundled;

[0027] When the transverse bundling of the packing box is completed, the packing box moves to the rotating plate 11, and the hydraulic rod 5 moves the first connecting plate 6 to rotate. The hydraulic rod 5 rotates relative to the fixed seat 4 and the first connecting plate 6, thereby driving the rotating drum 10 to rotate, causing the rotating plate 11 to rotate ninety degrees. Then the hydraulic machine 2 runs, causing the push plate 3 to push the packing box on the rotating plate 11, and under the action of the rolling ball 12, it slides to the transport bundling mechanism 7 on the other side, thereby bundling the packing box longitudinally. The above operations are repeated to realize the automated cross bundling process and improve work efficiency.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
