Description

Technical Field

[0001] This application relates to the technical field of packaging equipment, and in particular to a feeding device for an automatic cartoning machine for injection boxes. Background Technology

[0002] In the post-production packaging stage of injectable drug manufacturing, the boxing and sealing of injection vials is a crucial process for ensuring product transportation safety and meeting the requirements for conveying drug usage information. This process must strictly adhere to the mandatory requirements of drug regulatory laws regarding product information disclosure, and utilize automated packaging equipment to complete the core process—not only accurately delivering injection vials into packaging boxes, but also simultaneously inserting the paper printed with drug usage instructions into the corresponding packaging boxes, ensuring that each injectable product is accompanied by complete usage instructions, providing necessary guarantees for subsequent transportation, storage, and end-use.

[0003] However, in the operation of current automated packaging equipment, the feeding accuracy of instruction manuals directly affects packaging quality and compliance. This step heavily relies on the limiting structure of the feeding mechanism to achieve precise positioning and conveying, ensuring that the instruction manuals enter the packaging box accurately and in the correct position. However, current mainstream instruction manual feeding mechanisms have significant technical limitations: their limiting structures mostly adopt a fixed-size design, or require complex mechanical disassembly and replacement of specialized parts to adjust the limiting size. When production demands shift to different specifications of injectable products, the packaging box size and instruction manual size change simultaneously. This requires operators to spend significant time disassembling, replacing, or recalibrating the limiting components of the feeding mechanism. This adjustment not only severely impacts production changeover efficiency, leading to prolonged equipment downtime and reduced overall production efficiency, but also carries the risk of human error. If the limiting dimensions do not match the instruction manual size, it can easily cause problems such as instruction manual jamming and conveyor misalignment, compromising packaging quality stability and even increasing product rework costs. This negatively impacts the continuity and economy of the post-packaging process for injectable products. Utility Model Content

[0004] In view of the above-mentioned prior art, in order to solve the problems of inconvenient adjustment of the limit size of the instruction manual feeding mechanism and inability to quickly adapt to different specifications of instruction manuals, resulting in low production line changeover efficiency, this application provides a feeding device for an automatic cartoning machine for injection boxes.

[0005] The feeding device for an automatic cartoning machine for injection boxes provided in this application adopts the following technical solution: A feeding device for an automatic cartoning machine for injection boxes includes a frame, a storage platform for stacking instruction manual sheets, and a feeding roller for separating the stacked instruction manual sheets one by one from the storage platform and accurately conveying them to an external packaging station. The storage platform is mounted on the frame, and the feeding roller is located on one side of the storage platform and rotatably mounted on the frame. The storage platform is provided with a limiting mechanism for limiting the position of instruction manual sheets of different sizes. The limiting mechanism includes at least two opposing limiting plates, which are spaced apart on the top surface of the storage platform, with one end of each limiting plate facing the feeding roller along its length. The instruction manual sheets are located between the two limiting plates. The storage platform is also provided with an adjusting member for adjusting the two limiting plates to move further apart or closer together. When the instruction manual sheets are placed on the storage platform, one end of the sheet extends out of the storage platform and abuts against the surface of the feeding roller.

[0006] By adopting the above technical solution, the instruction manual paper on the storage platform can be laterally limited by the limiting plate to prevent the paper from shifting laterally during the conveying process. At the same time, the adjusting component can flexibly adjust the distance between the two limiting plates, adapting to instruction manual paper of different widths without disassembling or replacing parts. This significantly shortens the adjustment time when switching between different specifications of products on the production line, reduces equipment downtime, improves production efficiency, and reduces the risk of material jamming caused by mismatched limiting dimensions, ensuring the stability of material supply.

[0007] Preferably, the limiting mechanism further includes a limiting block, which is disposed between the two limiting plates and located at the end of the limiting plates away from the feed roller. The length direction of the limiting block is the same as that of the limiting plates. A first vertical rod is vertically disposed at the end of the limiting block near the limiting plates. A first adjustment hole is provided on the limiting block along its length direction. A bolt passes through the first adjustment hole, and the limiting block is fixed to the storage platform by the bolt.

[0008] By adopting the above technical solution, the limiting block, in conjunction with the first vertical rod, can form a longitudinal obstruction for the instruction manual paper, preventing longitudinal displacement of the paper when the storage platform is tilted or before conveying, thus ensuring that the initial position of each sheet of paper is uniform. The cooperation between the first adjusting hole and the bolt allows the operator to move the limiting block along the length direction to adjust its longitudinal position, thereby adapting to instruction manual paper of different lengths and specifications. This further improves the adaptability of the limiting mechanism to multiple paper specifications, and the adjustment operation is simple, requiring no replacement of the limiting block, thus reducing the difficulty of operation and time costs.

[0009] Preferably, a plurality of vertical second rods are provided on the opposite side of the two limiting plates, and the plurality of second rods are spaced apart along the length direction of the limiting plates.

[0010] By adopting the above technical solution, the second vertical rod can play an auxiliary role in limiting the edge of the instruction manual paper stacked between the limiting plates. Especially for thinner, easily curled or easily scattered paper, it can effectively reduce the situation of paper edges turning outward and stacking in a messy manner, further ensuring the stability of the paper's posture on the storage platform and laying the foundation for subsequent accurate delivery.

[0011] Preferably, the adjusting component is an adjusting plate, and there are two adjusting plates. The two adjusting plates are respectively located on opposite sides of the two limiting plates. One end of the adjusting plate along the length direction is fixedly connected to the limiting plate, and the other end of the adjusting plate is provided with a second adjusting hole along the length direction. A bolt is inserted into the second adjusting hole, and the end of the adjusting plate away from the limiting plate is fixedly connected to the storage platform by bolts.

[0012] By adopting the above technical solution, the adjusting plate, as an adjusting component, has a simple and stable mating structure with the second adjusting hole and bolt. The operator only needs to loosen the bolt to push the limiting plate and move the adjusting plate along the length direction of the second adjusting hole, quickly adjusting the distance between the two limiting plates to adapt to different paper widths. After adjustment, tightening the bolt will lock the position of the limiting plate. The entire process does not require disassembling the limiting plate, making the operation convenient and efficient, further shortening the changeover adjustment time, and ensuring the stability of the limiting plate's lateral constraint on the paper.

[0013] Preferably, vertical plates are fixedly provided on both sides of the storage platform along its length. One end of the vertical plate along its length is positioned towards the feed roller. The end of the vertical plate facing the feed roller is hinged to the frame. An angle adjustment component is provided at the end of the vertical plate away from the frame to drive the vertical plate to rotate around the hinge point to adjust the tilt angle of the storage platform.

[0014] By adopting the above technical solution, the hinged connection between the vertical plate and the frame provides a basis for adjusting the tilt angle of the storage platform; by using the angle adjustment component to drive the vertical plate to rotate, the feeding angle of the paper is adjusted to meet the matching position of the paper and the feeding roller, so as to achieve precise adjustment.

[0015] Preferably, the angle adjusting component is an arc-shaped plate, which has an arc-shaped hole along its length, and a bolt passes through the arc-shaped hole. The arc-shaped plate is fixedly connected to the vertical plate by bolts, and the end of the arc-shaped plate away from the vertical plate is fixedly connected to the frame.

[0016] By adopting the above technical solution, the arc plate, as an angle adjustment component, matches the trajectory of its arc hole with the rotation trajectory of the vertical plate around the hinge point. This allows the bolt to move synchronously within the arc hole when the vertical plate rotates, ensuring that the vertical plate can be stably locked in position at any adjusted angle. Operators only need to loosen the bolt to adjust the angle of the storage platform and tighten the bolt to fix it. The operation is simple and the angle adjustment is precise, which can effectively ensure the sliding speed and conveying stability of different specifications of paper on the storage platform.

[0017] Preferably, there are two limiting blocks, which are respectively positioned close to the two limiting plates at intervals.

[0018] By adopting the above technical solution, the two limiting blocks are set close to the two limiting plates respectively, which can simultaneously form a blockage from both sides of the longitudinal end of the paper. Compared with a single limiting block, it can more evenly limit the longitudinal movement of the paper, further avoiding longitudinal displacement or tilting of the paper due to uneven force on one side, ensuring a more uniform initial posture of the paper, and improving the accuracy of subsequent conveying and packaging.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. By adjusting the spacing of the limit plates with the adjusting parts, adjusting the longitudinal position of the limit block with the first adjusting hole, and adjusting the tilt angle of the storage platform with the arc plate, it can quickly adapt to instruction manuals of different widths, lengths, thicknesses and materials without disassembling or replacing parts, greatly improving the changeover efficiency of the production line. 2. The multi-limiting structure, consisting of lateral constraint of the limiting plate, longitudinal blocking of the limiting block and the first vertical rod, and auxiliary anti-scattering of the second vertical rod, combined with the appropriate tilt angle of the storage platform, can effectively prevent paper from shifting, moving or scattering during feeding, reduce the risk of jamming, and ensure that the paper enters the feeding roller and subsequent packaging station accurately. 3. Each adjustment mechanism is adjusted by bolts and adjustment holes. The operation is simple and requires no special tools or complex skills. This reduces the difficulty of operation, shortens the downtime for equipment adjustment, and improves the overall production continuity and economy. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0023] This application discloses a feeding device for an automatic cartoning machine for injection boxes.

[0024] Reference Figure 1 and Figure 2 A feeding device for an automatic cartoning machine for injection boxes includes a frame 1, a storage platform 2, and a feeding roller 3. The top surface of the storage platform 2 is used to store the instruction manual sheets to be connected. The storage platform 2 is rotatably mounted on one side of the frame 1. An angle adjustment component 4 for adjusting the tilt angle of the storage platform 2 is provided on the storage platform 2. The feeding roller 3 is located on the side of the storage platform 2 close to the frame 1 and is rotatably mounted on the frame 1. A limiting mechanism 5 for limiting the position of instruction manual sheets of different sizes is provided on the top surface of the storage platform 2.

[0025] Specifically, vertical plates 6 are fixedly installed on both sides of the storage platform 2 along its length. One end of the vertical plate 6 along its length faces the frame 1 and is hinged to the frame 1. An angle adjustment component 4 is located at the end of the vertical plate 6 away from the frame 1. The angle adjustment component 4 is an arc-shaped plate 41. An arc-shaped hole 411 is opened along the length of the end of the arc-shaped plate 41 near the vertical plate 6. A bolt passes through the arc-shaped hole 411, and the arc-shaped plate 41 is fixedly connected to the vertical plate 6 by the bolt.

[0026] When adjusting the tilt angle of the storage platform 2, the operator can first loosen the bolts connecting the arc plate 41 and the vertical plate 6. At this time, the vertical plate 6 is no longer fixed and can rotate freely around its hinge point with the frame 1. Based on the thickness and material characteristics of the instruction manual paper and the conveying requirements of the feed roller 3, the operator pushes the end of the storage platform 2 away from the frame 1 upwards or downwards to adjust the overall tilt angle of the storage platform 2. After the tilt angle of the storage platform 2 is adjusted to the optimal state for the current specification of instruction manual paper, the operator re-inserts the bolts into the arc hole 411 of the arc plate 41 and tightens them, thus fixing the vertical plate 6 and the arc plate 41 again. Since the trajectory of the arc hole 411 matches the rotation trajectory of the vertical plate 6 around the hinge point, the bolts can move synchronously with the rotation of the vertical plate 6 within the arc hole 411, ensuring that the position of the vertical plate 6 can be stably locked at any adjusted angle. This ultimately achieves precise adjustment and fixation of the tilt angle of the storage platform 2, ensuring that the instruction manual paper is conveyed to the feed roller 3 in a stable and smooth manner.

[0027] Specifically, the limiting mechanism 5 includes two opposing limiting plates 51 and limiting blocks 52. The two limiting plates 51 are spaced apart on the top surface of the storage platform 2, with one end of each limiting plate 51 facing the frame 1 along its length. The limiting blocks 52 are located at the ends of the limiting plates 51 away from the frame 1 and between the two limiting plates 51. An adjusting member 7 is provided on the storage platform 2 to adjust the distance between the two limiting plates 51; the distance between the two limiting plates 51 can be adjusted via the adjusting member 7, allowing for precise adaptation according to the actual dimensions of the instruction manual. Two limiting blocks 52 are provided, spaced apart and close to the two limiting plates 51. A first vertical rod 8 is vertically arranged at the end of each limiting block 52 close to the limiting plates 51 along its length, and multiple second vertical rods 9 are vertically arranged on the opposite sides of the two limiting plates 51. The limiting block 52 and the first vertical rod 8 form a longitudinal obstruction to the paper, and the second vertical rod 9 on the outside of the limiting plate 51 assists in preventing the paper from scattering. Combined with the lateral constraint of the limiting plate 51, multiple limiting of the paper is achieved, which effectively avoids deviation, displacement or scattering during conveying, ensures the uniformity of the initial position and the stability of the posture of the paper, thereby reducing the risk of jamming and ensuring that the paper accurately enters the feeding roller 3 and subsequent packaging station.

[0028] The length direction of the limiting block 52 is the same as that of the limiting plate 51. The limiting block 52 has a first adjustment hole 521 along its length direction, and a bolt passes through the first adjustment hole. The limiting block 52 is fixedly connected to the storage platform 2 by the bolt. The limiting block 52 is fixed to the storage platform 2 by the bolt through the first adjustment hole 521 along its length direction. The operator can loosen the bolt and move the limiting block 52 along the length direction of the first adjustment hole 521 to adjust the longitudinal position of the limiting block 52 on the storage platform 2, thereby adapting to instruction manual paper of different lengths. When the length of the instruction manual paper changes, there is no need to replace the limiting block 52. Simply adjusting its position can accurately correspond to the longitudinal end of the paper.

[0029] Furthermore, when the instruction manual paper is being conveyed, it is placed between the two limiting plates 51, with one end of the instruction manual paper along its length abutting against the limiting block 52 and the first vertical rod 8, and the other end of the instruction manual paper extending out of the storage platform 2 and abutting against the outer surface of the feed roller 3.

[0030] The adjusting component 7 is an adjusting plate 71. Two adjusting plates 71 are provided, each located on one side opposite to the two limiting plates 51. One end of the adjusting plate 71 along its length is bolted to the limiting plate 51. The end of the adjusting plate 71 away from the limiting plate 51 has a second adjusting hole 711 along its length, through which a bolt passes. The adjusting plate 71 is bolted to the storage platform 2. When the storage platform 2 is used to limit instruction manual sheets of different sizes, the operator can first loosen the bolts connecting the adjusting plate 71 to the storage platform 2. At this time, the adjusting plate 71 is no longer fixed. Since one end of the adjusting plate 71 is bolted to the limiting plate 51, pushing the limiting plate 51 will move the adjusting plate 71 along the length of the second adjusting hole 711, thereby adjusting the distance between the two limiting plates 51. If the instruction manual sheet is wide, the two limiting plates 51 can be pushed away from each other until the distance matches the sheet width; if the sheet is narrow, the two limiting plates 51 can be pushed closer together. After the spacing is adjusted to precisely constrain the current specification of the instruction manual paper, the bolt is re-inserted into the second adjustment hole 711 and tightened to fix the adjustment plate 71 to the storage platform 2, thereby locking the position of the limit plate 51. The entire process does not require disassembling the limit plate 51 or replacing parts. The lateral limit dimension can be adjusted simply by loosening, moving, and tightening the bolts, which can quickly adapt to instruction manual paper of different widths, reduce equipment downtime during production line changeovers, and ensure the stability of the lateral constraint of the limit plate 51 on the paper. This prevents the paper from shifting or jamming during transportation due to mismatched lateral spacing, further ensuring the accuracy of feeding and subsequent packaging.

[0031] When switching between different sizes of instruction manual paper, the operator must first loosen the connecting bolts between the arc plate 41 and the vertical plate 6, adjust the tilt angle of the storage platform 2 according to the thickness, material, and feed roller 3 requirements of the new paper size, and then tighten the bolts to fix it; then loosen the bolts between the adjusting plate 71 and the storage platform 2, push the limiting plate 51 fixed to the adjusting plate 71 to move along the second adjusting hole 711, adjust the lateral distance between the two limiting plates 51 to match the paper width, and tighten the bolts; next, loosen the bolts between the limiting block 52 and the storage platform 2, move the limiting block 52 along the first adjusting hole 521 to match the paper length with the first vertical rod 8, and then tighten the bolts; finally, stack the new paper size between the two limiting plates 51, ensuring that one end of the paper abuts against the limiting block 52 and the first vertical rod 8, and the other end extends out of the storage platform 2 to abut against the feed roller 3. The feed roller 3 can then rotate to separate the paper one by one and accurately transport it to the external packaging station, realizing the switching of different paper sizes.

[0032] The implementation principle of this application embodiment is as follows: With "adapting to multiple specifications of instruction manual paper and achieving stable and precise material supply" as the core, the adjustable storage platform 2 and the limiting mechanism 5 work together to first complete the initial adaptation adjustment according to the specifications of the instruction manual paper, and then rely on the structural design to ensure conveying stability. Firstly, considering the thickness and material characteristics of different papers, the paper feeding angle is adjusted by the hinged cooperation of the arc plate 41 and the vertical plate 6, and the guiding effect of the arc hole 411, to meet the matching position of the paper and the feeding roller 3, achieving precise adjustment. Secondly, considering the differences in paper width and length, the limiting plate 51 is moved along the second adjusting hole 711 and the limiting block 52 is moved along the first adjusting hole 521 by the adjusting plate 71, respectively, to achieve fine adjustment of the lateral spacing and longitudinal position of the limiting mechanism 5. Combined with the longitudinal blocking of the first vertical rod 8, the auxiliary anti-scattering of the second vertical rod 9, and the lateral approximation of the limiting plate 51... The paper is bundled to form a multi-limiting structure, ensuring that the initial position of the paper is uniform and the posture is stable, avoiding conveying deviation and jamming. Finally, the adapted paper is stacked in the limiting mechanism 5, so that one end of the paper abuts against the limiting structure and the other end contacts the feeding roller 3. Using the inclined potential energy of the storage platform 2 and the friction of the feeding roller 3, the paper is separated one by one and accurately conveyed to the external packaging station. At the same time, when changing paper specifications, the adaptation of each structure can be completed by simply loosening, adjusting and tightening the bolts, without disassembling or replacing parts, which greatly improves the changeover efficiency and feeding accuracy of the production line and meets the feeding requirements of the instruction manual for automatic boxing of injection boxes.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
