Description

Technical Field

[0001] This utility model relates to the technical field of capping machines for ibuprofen suspension, and particularly to a capping machine for ibuprofen suspension. Background Technology

[0002] A capping machine, also known as a sealing machine, pressing machine, or locking machine, is a device used to tighten and loosen caps on plastic and glass bottles after they have been dispensed. In the production process of ibuprofen suspension, a capping machine is required to seal the packaging bottles.

[0003] In the existing technology, if the cap is reversed (i.e., the bottle cap is placed in the wrong direction) in the cap lifting machine, and the operator does not notice and stop the machine in time, the cap will enter the capping head. Then the machine needs to be stopped to remove the deformed cap and bottle, and clean the liquid in the equipment and mold. The production stoppage will take 20-30 minutes per time, which has a significant impact on the efficiency of the filling site and also brings potential quality problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a capping machine for ibuprofen suspension, which aims to solve the technical problem that reverse capping affects production efficiency in the existing technology.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0022] Please see Figures 1 to 3The image shows a capping machine for ibuprofen suspension according to an embodiment of the present invention. It includes a capping mechanism 10 and a cap lifting mechanism disposed on the upper side of the capping mechanism 10. The capping mechanism 10 includes a capping head 11 and a feeding bin 12 connected to the cap lifting mechanism. The cap lifting mechanism includes a cap lifting bin, a feeding track 31 disposed on the upper side of the feeding bin 12, and a cap conveying mechanism disposed between the cap lifting bin and the feeding track 31. The ibuprofen suspension capping machine also includes a bottle cap detection mechanism disposed between the feeding track 31 and the feeding bin 12. The bottle cap detection mechanism includes a cap conveying mechanism disposed on the feeding track 31. The bottle cap detection mechanism includes a detection bracket 41 on one side and a pusher plate 43 on one side of the detection bracket 41. A first electric pusher rod 42 is provided on one side of the pusher plate 43. A baffle 44 is also provided on the side of the detection bracket 41 away from the feeding track 31. The baffle 44 is connected by a second electric pusher rod 45. The bottle cap detection mechanism also includes a mounting bracket 50 on the feeding track 31. A detection sensor 51 is provided on the mounting bracket 50. The first electric pusher rod 42 and the second electric pusher rod 45 are both electrically connected to the detection sensor 51. A receiving trough 60 is provided on the side of the pusher plate 43 away from the feeding bin 12.

[0023] In some application scenarios of this embodiment, bottle caps piled up in the cap lifting hopper are sorted by vibration and then moved to the unloading hopper 12 based on the cap conveying mechanism and the unloading track 31 with the correct placement surface. Since "reverse caps" are inevitable during the cap lifting process, that is, the bottle caps are placed in the wrong direction, a detection bracket 41 is set between the unloading track 31 and the unloading hopper 12. The detection bracket 41 is equipped with a detection sensor 51 to screen the "reverse caps" and remove them to the receiving trough 60 by the pusher plate 43, so as to prevent the "reverse caps" from flowing into the capping head 11 and causing problems such as bottle deformation and leakage.

[0024] Preferably, in this embodiment, the detection sensor 51 is a distance sensor. Understandably, by measuring the distance difference between the cap and the distance sensor, it can be determined whether the cap is placed upside down, thereby deciding whether to remove it by using the first electric push rod 42, or to use the second electric push rod 45 to lower the baffle 44 and let it flow into the feeding hopper 12 for subsequent capping operations.

[0025] Preferably, in this embodiment, the bottle cap detection mechanism further includes a CCD camera disposed on the upper side of the detection bracket 41, and the CCD camera is electrically connected to the first electric push rod 42. By setting the CCD camera, defective bottle caps with missing caps, i.e., caps missing due to poor injection molding, can be detected. Similarly, the defective bottle caps are screened out by the pusher plate 43 and sent to the receiving trough 60, preventing the defective bottle caps from flowing into the capping head 11 and causing problems such as bottle deformation and leakage, thereby improving production efficiency.

[0026] Furthermore, in this embodiment, the detection bracket 41 includes a support plate 41a disposed near the unloading track 31, and a mounting plate 41b vertically disposed on the lower side of the support plate 41a, with the second electric push rod 45 disposed on the mounting plate 41b. Even further, in this embodiment, the support plate 41a is used to receive bottle caps output from the unloading track 31. To prevent bottle caps from sliding directly out of the support plate 41a from the side near the receiving trough 60, the support plate 41a is inclined, i.e., the side with the lower bottom horizontal height is disposed near the pusher plate 43, so that the bottle caps can be placed near the pusher plate 43 after being output.

[0027] Preferably, in this embodiment, the cap conveying mechanism includes a conveyor belt body 21 and a plurality of locking strips 22 evenly spaced on the conveyor belt body 21. The locking strips 22 are used to limit the bottle caps and prevent them from slipping off the conveyor belt body 21. Specifically, the feeding track 31 includes a feeding plate disposed near the side of the conveyor belt body 21 and a feeding pipe disposed on one side of the feeding plate. The feeding plate is provided with limiting blocks corresponding to the feeding pipe. It can be understood that the feeding plate and the feeding track 31 are both inclined to utilize gravity to move and convey the bottle caps.

[0028] Preferably, in this embodiment, the cap conveying mechanism further includes a limiting strip 23 disposed on the side of the conveyor belt body 21 near the unloading track 31. The limiting strip 23 is disposed on the side away from the conveyor belt body 21 near the unloading track 31. The horizontal height of the limiting strip 23 is higher than that of the locking strip 22, and it is used to limit the cap when it approaches the unloading track 31, and to move it towards the unloading track 31.

[0029] Furthermore, in this embodiment, the ibuprofen suspension capping machine also includes a bottle body conveying mechanism located on one side of the capping head 11. In some application scenarios of this embodiment, the bottle containing the ibuprofen suspension is conveyed to the capping head 11 via the bottle body conveying mechanism. The capping head 11 then picks up the cap from the feeding hopper 12 and screws the cap onto the bottle body, completing the capping and sealing of the bottle.

[0030] In summary, the ibuprofen suspension capping machine in the above embodiments of this utility model has a cap detection mechanism set between the feeding track 31 and the feeding bin 12 of the capping mechanism 10. The cap detection mechanism includes a detection bracket 41 on one side of the feeding track 31, a detection sensor 51 on the upper side of the detection bracket 41, and a pusher plate 43 on one side of the detection bracket 41. A first electric push rod 42 is provided on one side of the pusher plate 43, and the first electric push rod 42 is electrically connected to the detection sensor 51. A receiving groove 60 is provided on the side of the pusher plate 43 away from the feeding bin 12. The detection sensor 51 detects the height of the caps on the detection bracket 41 to determine whether there are reverse caps, and pushes them into the receiving groove 60 by the pusher plate 43, preventing incorrectly placed caps from entering the capping head 11 and affecting production efficiency.
