Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging technology, specifically an automatic packaging device for pharmaceutical packaging boxes. Background Technology

[0002] On pharmaceutical packaging production lines, after the medicines are boxed, the flaps or lids of the packaging boxes need to be folded and sealed. Existing automated packaging equipment typically uses fixed folding guides or rotating folding arms to scrape or press the moving packaging boxes to complete the folding action.

[0003] However, the applicant discovered that in actual production, in addition to medicines, packaging boxes often contain other items such as instruction manuals and desiccants. These items may not be stacked perfectly flat, causing the lid to be subjected to upward pressure from the contents after folding. Existing folding mechanisms separate from the lid after the folding action is completed, failing to provide sustained constraint. At this point, the elastic paper lid is highly susceptible to automatically springing open under the internal upward pressure, creating an "open mouth" phenomenon. This seemingly minor issue can lead to failure in subsequent sealing processes, resulting in defective products or requiring additional manual intervention for rework, severely impacting the efficiency and continuity of the production line. Therefore, there is an urgent need in this field for a simple and reliable mechanism that can effectively prevent the lid from automatically springing back during the period between folding and sealing. Utility Model Content

[0004] (a) Technical problems to be solved The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic packaging device for pharmaceutical packaging boxes.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: an automatic packaging device for pharmaceutical boxes, comprising a frame, a support frame fixed above the frame, and a roller conveyor arranged between the frames for conveying packaging boxes. A second bearing is embedded in the support frame, and a second rotating shaft passes through the second bearing. A first threaded rod and a second threaded rod are fixed to the two ends of the second rotating shaft, respectively. The threads of the first and second threaded rods are in opposite directions. A first threaded block is threaded onto the first threaded rod, and a second threaded block is threaded onto the second threaded rod. When the first and second threaded rods rotate, the first and second threaded blocks can move relative to or away from each other. An anti-rebound mechanism is provided at the horizontal center of the support frame for pressing down the folded edges of the packaging boxes. Guide mechanisms are fixed to the bottom ends of the first and second threaded blocks, respectively. The anti-rebound mechanism is located at the symmetrical center of the first and second threaded blocks.

[0006] Furthermore, a first rotating shaft is fixed to the other end of the first threaded rod and the second threaded rod. A first bearing is sleeved on the surface of the first rotating shaft. The first bearing is embedded in the support frame. The first rotating shaft passes through the first bearing and is fixed with a handle.

[0007] Furthermore, the anti-rebound mechanism includes a lower pressure plate, a first telescopic rod, a first spring, a guide groove, a guide wheel, and a flat pressure wheel. The upper end of the first telescopic rod is connected to the support frame, and the lower end is connected to the lower pressure plate. The first spring is sleeved on the first telescopic rod, and the upper end of the first spring is connected to the support frame, and the lower end is connected to the lower pressure plate. A guide groove is provided at one end of the lower pressure plate. The guide groove gradually narrows in width from the inlet to the inside and the bottom of the groove slopes downward. The end of the guide groove is located below the lower pressure plate and a guide wheel is fixed thereon. At least one flat pressure wheel is horizontally fixed behind the guide wheel.

[0008] Furthermore, the guiding mechanism includes a guide plate, rollers, a second telescopic rod, and a second spring. The upper end of the second telescopic rod is fixed to the bottom end of the first threaded block or the second threaded block, and the lower end is fixed to the guide plate. The second spring is sleeved on the second telescopic rod, and the upper end of the second spring is connected to the bottom end of the first threaded block or the second threaded block, and the lower end is connected to the guide plate. At least one roller is fixed to the bottom end of the guide plate.

[0009] Furthermore, the inlet end of the guide plate is provided with an inclined arc surface.

[0010] Furthermore, the first threaded block and the second threaded block are provided with limiting grooves, and a limiting rod is inserted through the limiting grooves. The limiting rod is fixed to the guide plate.

[0011] Furthermore, as stated above.

[0012] (III) Beneficial Effects: Compared with existing technologies, this automatic packaging equipment for pharmaceutical packaging boxes has the following advantages: I. This utility model, by setting two threaded blocks driven by a reverse threaded rod, allows for synchronous and precise adjustment of the distance between the two guide plates simply by turning the handle. This design enables the equipment to quickly adapt to packaging boxes of various widths, greatly improving the equipment's versatility and flexibility in production, and eliminating the tedious steps of changing molds or parts.

[0013] Second, this utility model uses an anti-rebound mechanism that combines a "guide groove, guide wheel, and flat pressure wheel" to gradually flatten the pop-up lid. The guide groove first gathers the raised edge and guides it to the correct position, and then the flat pressure wheel applies stable pressure to completely flatten it. This mechanism solves the problem of the lid popping open due to the support of the contents, ensuring a flat packaging appearance and providing a reliable prerequisite for subsequent automatic sealing.

[0014] Third, this utility model integrates springs and telescopic rods through a guiding mechanism, enabling the guide plate to float up and down. This elastic design can effectively absorb the vibrations and fluctuations that may occur during the operation of the roller conveyor, ensuring that the box passes through smoothly. The rollers at the bottom greatly reduce the frictional resistance with the roller conveyor, protecting the surface of the packaging box and ensuring smooth transmission. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0018] like Figure 1-9 As shown, this embodiment provides an automatic packaging equipment for pharmaceutical packaging boxes, including a frame 1, a support frame 2 fixed above the frame 1, and a roller conveyor 3 arranged between the frames 1. The roller conveyor 3 is driven by a motor to rotate and is used to transport the packaging boxes 4 to be packaged. A second bearing 14 is embedded in the support frame 2, and a second rotating shaft 13 is inserted through the second bearing 14. A first threaded rod 10 and a second threaded rod 15 are fixed at both ends of the second rotating shaft 13, respectively. The threads of the two are opposite in direction. A first threaded block 5 is threadedly connected to the first threaded rod 10, and a second threaded block 9 is threadedly connected to the second threaded rod 15. When the first threaded rod 10 and the second threaded rod 15 rotate synchronously, the first threaded block 5 and the second threaded block 9 can move relative to each other or towards each other. The other end of the first threaded rod 10 and the second threaded rod 15 is fixed with a first rotating shaft 12. The first rotating shaft 12 is mounted on the support frame 2 through a first bearing 11. The first rotating shaft 12, which passes through the outer end of the support frame 2, is connected to a handle 7 for manually driving the threaded rod to rotate and adjusting the distance between the threaded blocks. The guide operation of packaging boxes 4 of different sizes is realized according to the distance between the two guide plates 801.

[0019] An anti-rebound mechanism 6 is provided at the horizontal center of the support frame 2, and this anti-rebound mechanism 6 is located at the symmetrical center of the first threaded block 5 and the second threaded block 9, such as... Figures 1 to 4 As shown, the anti-rebound mechanism 6 includes a lower pressure plate 601, a first telescopic rod 602, a first spring 603, a guide groove 604, a guide wheel 605, and a flat pressure wheel 606. The upper end of the first telescopic rod 602 is connected to the support frame 2 through a fixed plate, and the lower end is connected to the lower pressure plate 601. The first spring 603 is sleeved on the first telescopic rod 602, with its upper end connected to the support frame 2 and its lower end connected to the lower pressure plate 601, providing elastic downward pressure. The guide groove 604 at one end of the lower pressure plate 601 gradually contracts from the outside to the inside and tilts downward. The end is provided with a guide wheel 605, and the rear is provided with a flat pressure wheel 606, which is used to gradually press down and flatten the folded edge, which can solve the problem of the box cover automatically popping open due to the support of the contents. By gradually flattening the supported plate, it is convenient for subsequent sealing.

[0020] like Figure 4 , Figure 5 , Figure 8 and Figure 9As shown, the bottom of the first threaded block 5 and the second threaded block 9 are respectively equipped with a guide mechanism 8. The guide mechanism 8 includes a guide plate 801, a roller 802, a second telescopic rod 803 and a second spring 804. The upper end of the second telescopic rod 803 is fixed to the bottom of the threaded block, and the lower end is connected to the guide plate 801. The second spring 804 is sleeved on the second telescopic rod 803. Its upper end is connected to the bottom end of the first threaded block 5 (or the second threaded block 9), and its lower end abuts against the surface of the guide plate 801, thereby providing elastic preload. The inlet end of the guide plate 801 is provided with an inclined arc surface, and the bottom is provided with a roller 802 for guiding the packaging box 4 in. The rolling path at the bottom end of the guide plate 801 will rotate in coordination with the roller conveyor 3, which can also reduce the friction between the roller conveyor 3 and the guide plate 801.

[0021] The first threaded block 5 and the second threaded block 9 are provided with limiting grooves 16, and limiting rods 17 are inserted therein and fixed to the guide plate 801 to limit the vertical movement range of the guide plate 801 and ensure motion stability.

[0022] Workflow: Adjusting the guide spacing: Based on the width of the packaging box 4 to be packaged, turn the handle to drive the first threaded rod 10 and the second threaded rod 15 to rotate synchronously through the first rotating shaft 12. Since the threads of the two threaded rods are opposite, the first threaded block 5 and the second threaded block 9 move towards or relative to each other, thereby adjusting the spacing between the two guide plates 801 to accommodate packaging boxes 4 of different sizes.

[0023] Guiding and positioning: After the packaging box 4 is folded, it enters between the two guide plates 801 along with the roller conveyor 3. The inclined arc surface at the inlet end of the guide plate 801 guides the box to enter in the center. The roller 802 at the bottom reduces the friction between the guide plate 801 and the roller conveyor 3. The second spring 804 and the second telescopic rod 803 enable the guide plate 801 to float up and down to adapt to the undulations when the roller conveyor 3 moves.

[0024] Folding and pressing: When the packaging box 4 continues to move forward to the bottom of the anti-rebound mechanism 6, the folded edge first enters the guide groove 604. The groove structure gradually narrows and deepens, gradually closing and pressing down the folded edge. The guide wheel 605 assists in the transition of the folded edge. Then the flat pressing wheel 606 finally flattens the folded edge, and then further sealing is carried out.

[0025] Packaging complete: After being pressed down and flattened, the four folds of the packaging box are completely processed, and then it is sent out of the equipment by roller conveyor 3, completing the automatic packaging process.
