[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0032] Reference Figures 1-3This utility model provides an embodiment of a positioning device for pharmaceutical packaging, comprising a conveyor frame 1. A cylinder 2 is mounted on the side wall of the conveyor frame 1. The cylinder 2 is a cylindrical metal component that guides a piston in linear reciprocating motion within the cylinder. The contact tube 11 is positioned by the cylinder 2. A labeling machine 3 is mounted on the side wall of the conveyor frame 1. The labeling machine 3 is an automated device for affixing labels to pharmaceutical packaging such as medicine bottles and boxes, and is indispensable in pharmaceutical production. As it is existing technology, it will not be described in detail. A connecting block 4 is fixedly connected to the movable end of the cylinder 2. An installation block 5 is inserted into the inner wall of the connecting block 4, and the right end of the installation block 5 slides. The mounting block 5 is connected to an extension plate 6. The front and rear ends of the mounting block 5 are long plates, which can allow the extension plate 6 to move on the long plates. The top of the extension plate 6 is fixedly connected to an L plate 7. The outer wall of the L plate 7 is provided with a positioning mechanism. The right end of the mounting block 5 is provided with a positioning plate 9. The left side wall of the positioning plate 9 is fixedly connected to an airbag 10. The airbag 10 is elastic and expands to the left when inflated. The inner wall of the positioning plate 9 is penetrated and connected to a contact tube 11. The right end of the contact tube 11 is made of rubber material, which will not damage the medicine when in contact with it. The positioning plate 9 has a cavity, which can allow the contact tube 11 to move in the cavity. The inner wall of the connecting block 4 is provided with a limit component.
[0033] The positioning mechanism includes a fixing block 8, which is slidably connected to the outer wall of the L plate 7. The fixing block 8 has a corresponding slot for the locking block 13, which can allow the locking block 13 to move vertically along the slot. The locking block 13 is elastically connected to the inner wall of the top of the fixing block 8 through a return spring 12.
[0034] Reference Figure 1 and Figure 5 The limiting component includes an insert block 15, which is slidably connected to the inner wall of the connecting block 4. The connecting block 4 has a corresponding slot for the insert block 15, which allows the insert block 15 to move along the slot. The rear end of the insert block 15 is elastically connected to the connecting block 4 through a positioning spring 14. The rear end of the insert block 15 is fixedly connected to one end of the positioning spring 14. When the insert block 15 moves backward, it will compress the positioning spring 14. When resetting, the elastic force of the positioning spring 14 will bring the insert block 15 back to its original position. The other end of the positioning spring 14 is fixedly connected to the inner wall of the rear end of the connecting block 4. The insert block 15 is inserted into the rear side of the mounting block 5.
[0035] Reference Figures 2-4The top inner wall of the fixed block 8 is fixedly connected to one end of the return spring 12. When the locking block 13 moves upward, it will compress the return spring 12. When resetting, the elastic force of the return spring 12 will carry the locking block 13 to reset. The other end of the return spring 12 is fixedly connected to the top of the locking block 13. The locking block 13 is locked onto the top of the L plate 7. The top of the L plate 7 has an opening, which can satisfy the locking block 13 to be locked into the opening, and can limit the L plate 7. The fixed block 8 is fixedly connected to the top of the positioning plate 9. The contact tube 11 passes through and is connected to the inner wall of the extension plate 6. The airbag 10 is fixedly connected to the left side wall of the extension plate 6. The extension plate 6 and the positioning plate 9 are the same, both of which have components such as the airbag 10 and the contact tube 11. The positioning plate 9 and the airbag 10 are connected to each other. The extension plate 6 and the airbag 10 are connected to each other.
[0036] Working principle: When labeling is required, simply place the medicine onto the conveyor belt of the conveyor rack 1. The conveyor belt starts and transports the medicine towards the labeling machine 3 at a preset speed, triggering the cylinder 2. The piston rod of the cylinder 2 extends, pushing the connecting block 4 and its connected mounting block 5, positioning plate 9, and extension plate 6 towards the medicine. The positioning plate 9 and extension plate 6 gradually approach the sides of the medicine. When the rubber end of the contact tube 11 first contacts the surface of the medicine, due to the obstruction of the medicine, the contact tube 11 begins to slide relative to the cavity of the positioning plate 9 and extension plate 6. The sliding of the contact tube 11 causes the gas inside the positioning plate 9 and extension plate 6 to be compressed, and the gas passes through... The channel enters the airbag 10, causing it to inflate. The inflated airbag 10 applies gentle pressure to the surface of the medicine, working in conjunction with the contact tube 11 to achieve flexible positioning of the medicine. This ensures the medicine remains stable during labeling and can adapt to the positioning of irregular medicines. After the medicine is precisely positioned, the labeling machine 3 starts to label it. After labeling is completed, the movable end of the cylinder 2 retracts, causing the connecting block 4, mounting block 5, and positioning plate 9 to move away from the medicine. As the positioning plate 9 and extension plate 6 retract, the contact tube 11 is no longer squeezed by the medicine. The gas inside the airbag 10 pushes the contact tube 11 back to its initial state, and the airbag 10 contracts back to its initial state.
[0037] If the relative positions of the positioning plate 9 and the extension plate 6 need to be adjusted to accommodate medicines of different sizes, the locking block 13 can be pulled upward to compress the return spring 12, so that the locking block 13 is disengaged from the opening of the L plate 7. Then, the extension plate 6 is moved to move the L plate 7 backward, increasing the distance between the positioning plate 9 and the extension plate 6. When a limit is needed, simply release the locking block 13 and use the reverse elastic force of the return spring 12 to lock the locking block 13 onto the L plate 7.
[0038] When maintenance or replacement of the entire positioning component is required, simply pull the insert 15 backward to compress the positioning spring 14, causing the insert 15 to disengage from the slot of the mounting block 5. At this time, the mounting block 5 can be pulled out from the connecting block 4 for subsequent maintenance work. When installation is required, simply insert the entire mounting block 5 into the connecting block 4, then release the insert 15. The positioning spring 14 will push the insert 15 back into the slot of the new mounting block 5, completing the quick replacement.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
