[0002] Ampoules are a widely used packaging container in pharmaceutical packaging. The text information on their surface, including the name of the medicine, volume, production date, batch number, etc., is related to the life safety of users. Accordingly, the printing of this information needs to be completed by an ampoule printing machine.

[0003] The existing devices for printing on medicine bottles have the following problems during use: First, the height of the printing mechanism is usually fixed. When printing on medicine bottles of different sizes, the printing mechanism needs to be disassembled and adjusted, which is inconvenient, time-consuming and labor-intensive. Second, some medicine bottles without printed text or with unclear printed text cannot be rejected in time, which increases the difficulty of sorting. Utility Model Content

[0004] The purpose of this utility model is to provide a medicine bottle printing device that can flexibly adjust the height of the printing mechanism according to the needs, thereby meeting the printing requirements of medicine bottles of different sizes. It is easy and quick to operate. In addition, through the cooperation of the visual bottle inspection mechanism and the defect rejection mechanism, medicine bottles without printed text information or with unclear printing can be rejected in time, making up for the difficulty of subsequent sorting and ensuring packaging quality.

[0005] The present invention adopts the following technical solution:

[0006] A medicine bottle printing device includes a feeding mechanism and a printing mechanism mounted on a frame. The feeding mechanism has a conveying mechanism at its discharge end, and the printing mechanism is located above the conveying mechanism. A visual bottle inspection mechanism is provided on one side of the conveying mechanism, and a defect rejection mechanism is provided at the end of the conveying mechanism. The printing mechanism includes a coating transfer printing head and a printing head. Both the coating transfer printing head and the printing head have mounting seats on their backs. The mounting seats are matched and connected to a lead screw mounted on the frame, and the lead screw is driven by a motor.

[0009] Preferably, the flower disc is provided with a plurality of teeth grooves evenly arranged along its circumference, and each tooth groove is provided with an air hole that is connected to the air source pipe. The side of the flower disc away from the crescent-shaped baffle is connected to the pneumatic slip ring through the air source pipe; the pneumatic slip ring is connected to the solenoid valve.

[0010] Preferably, a detection frame is provided below the flower plate, and a slider that can slide up and down is elastically provided on the detection frame. A detection plate is provided at the bottom of the slider, and a trigger switch is provided below the detection plate.

[0028] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0029] like Figures 1 to 10As shown, the medicine bottle printing device of this utility model includes a feeding mechanism 2 and a printing mechanism 3 mounted on a frame 1. The feeding mechanism 2 includes a feeding platform and a feeding screw and a spiral track located at the discharge end of the feeding platform. During operation, the feeding platform orderly arranges the medicine bottles so that they change from a vertical state to a horizontal state after passing through the feeding screw and spiral track, and then enters the conveying mechanism 4 for conveying, so as to facilitate the printing mechanism 3 to print relevant text information above the medicine. The discharge end of the feeding mechanism 2 is provided with a conveying mechanism 4, and the printing mechanism 3 is located above the conveying mechanism 4. A visual bottle inspection mechanism 5 is provided on one side of the conveying mechanism 4 to identify medicines without printed text information or with unclear printing and to promptly feed back the identified position results to the PLC. The PLC will count, and a defect rejection mechanism 6 is provided at the end of the conveying mechanism 4 to reject defective medicine bottles by acquiring the above-mentioned identification information, so as to ensure the printing quality of the medicine bottles conveyed later.

[0030] The defect removal mechanism 6 in this embodiment specifically includes a photoelectric detector 6-1 set on one side of the conveying mechanism 4, which is used to re-inspect the medicine bottles with printing defects to improve the accuracy of identification. A cylinder 6-2 is set on the same side as the photoelectric detector 6-1, and a collection box 6-3 is set on the side of the conveying mechanism 4 opposite to the cylinder 6-2. When working, after receiving the control information, the cylinder 6-2 starts to push the defective medicine bottles off the conveying mechanism 4, so that they enter the collection box 6-3 for centralized storage, which facilitates subsequent centralized processing.

[0031] In this embodiment, the printing mechanism 3 includes a coating transfer printing head 3-1 and a printing head 3-2. Both the coating transfer printing head 3-1 and the printing head 3-2 have mounting seats 3-3 on their backs. The mounting seats 3-3 are matched and connected to a lead screw 3-4 mounted on the frame 1. The lead screw 3-4 is driven by a motor 3-5. Specifically, pulleys 3-6 are provided at the top of both the lead screw 3-4 and the motor 3-5. A transmission belt 3-7 is fitted onto the pulleys 3-6, ensuring transmission efficiency through belt drive, while also providing low noise and a simple, easy-to-adjust structure. Furthermore, the motor 3-5 in this embodiment is equipped with a brake to ensure that the motor 3-5 is locked in the stopped state, thereby ensuring the stability of the positions of the coating transfer printing head 3-1 and the printing head 3-2 during operation and guaranteeing printing quality.

[0032] Furthermore, such as Figure 3As shown, in this embodiment, the conveying mechanism 4 includes a mounting frame 4-1 connected to the frame 1. A first conveying chain 4-2 is provided on the mounting frame 4-1. A bracket 4-3 is provided on the mounting frame 4-1 at the end of the first conveying chain 4-2. A crescent-shaped baffle 4-4 that can move along its length is elastically provided on the bracket 4-3. A detection rod 4-5 is provided on one side of the crescent-shaped baffle 4-4. In the initial state, the detection rod 4-5 is in contact with the detection switch 4-6 provided on the mounting frame 4-1. A pneumatically controlled flower disc 4-7 is provided on the rear side of the crescent-shaped baffle 4-4. A conveying track is provided on the lower side of the flower disc 4-7. A second conveying chain 4-8 is provided at the discharge end of the conveying track. A visual bottle inspection mechanism 5 is provided on the side of the second conveying chain 4-8. A defect rejection mechanism 6 is provided on both sides of the second conveying chain 4-8 near the end. During operation, medicine bottles are conveyed by the first conveyor chain 4-2 and output from the lower end of the crescent-shaped baffle 4-4. The flower disc 4-7 picks up the bottles one by one and transports them to the conveyor track. The conveyor track and its internal screws work together to change the bottles from a horizontal to an vertical position. The bottles then enter the subsequent second conveyor chain 4-8 for further transport. If a bottle on the first conveyor chain 4-2 is not in the correct position during transport, it will exert a pushing force on the crescent-shaped baffle 4-4 when it reaches it, causing the baffle to move away from the first conveyor chain 4-2. At this point, the detection rod 4-5 disengages from the detection switch 4-6. Upon receiving this signal, the equipment PLC immediately stops the machine for timely maintenance and adjustment, preventing ampoule breakage from continued transport. This significantly reduces the ampoule breakage rate and minimizes economic losses during production.

[0033] In this embodiment, a slide rail 4-9 is provided on the inner side of the bracket 4-3, and a connecting plate 4-10 is provided on one side of the crescent-shaped baffle 4-4. The connecting plate 4-10 is provided with a sliding groove that slides in contact with the slide rail 4-9, and a first return spring is provided between the connecting plate 4-10 and the bracket 4-3. When the crescent-shaped baffle 4-4 moves away from the chain conveyor, the first return spring is stretched, and the detection rod 4-5 disengages from the detection switch 4-6. At this time, the equipment stops. Since the first return spring has a certain restoring force, the medicine bottle with an incorrect position will be clamped between the crescent-shaped baffle 4-4 and the first conveyor chain 4-2, preventing the medicine bottle from falling, reducing the probability of the medicine bottle breaking, and reducing economic losses. In addition, a limit plate 4-12 is also provided on the bracket 4-3, and a limit rod 4-13 is provided on the connecting plate 4-10 on one side of the crescent-shaped baffle 4-4. The contact between the limiting rod 4-13 and the limiting plate 4-12 limits the crescent-shaped baffle 4-4 during reset, preventing it from moving rapidly under elastic restoring force and damaging the medicine bottle. Additionally, the limiting rod 4-13 is threaded onto the connecting plate 4-10, allowing adjustment of its extension length from the connecting plate 4-10 by rotating the rod. This changes the distance between the connecting plate 4-10 and the limiting plate 4-12, thereby adjusting the distance between the crescent-shaped baffle 4-4 and the chain conveyor to accommodate different types of ampoules.

[0034] Furthermore, the flower disc 4-7 is evenly provided with multiple toothed grooves 4-14 along its circumference. Each toothed groove 4-14 is provided with an air hole that communicates with the air source pipe 4-11. The side of the flower disc 4-7 away from the crescent baffle 4-4 is connected to a pneumatic slip ring through the air source pipe 4-11. The pneumatic slip ring is connected to a solenoid valve so that the PLC of the equipment can control the vacuum valve to open and achieve the adsorption of ampoules. During operation, the flower disc 4-7 rotates and uses the toothed grooves 4-14 to adsorb and pick up the ampoules output from the bottom of the crescent baffle 4-4 one by one. Using vacuum adsorption to pick up ampoules can avoid rubbing off the lettering printed on the ampoules and ensure production quality.

[0035] In addition, a detection frame 4-15 is installed below the flower plate 4-7. A sliding block 4-16 is elastically mounted on the detection frame 4-15 and can slide up and down. A detection plate 4-17 is located at the bottom of the sliding block 4-16, and a trigger switch 7 is located below the detection plate 4-17. When the vacuum of the flower plate 4-7 fails to function and cannot adsorb the medicine bottle, the bottle will fall onto the sliding block 4-16 below. The sliding block 4-16 will then move downwards, causing the detection plate 4-17 to move down and contact the trigger switch 7. At this time, the PLC will receive a relevant signal and issue a stop instruction for timely maintenance and adjustment. This further reduces the breakage rate of medicine bottles during operation and avoids a series of subsequent malfunctions, ensuring smooth production. Preferably, the detection frame 4-15 is threaded with an adjusting rod 4-18, and the slider 4-16 has a through hole for the adjusting rod 4-18 to pass through. Both the adjusting rod 4-18 and the through hole have a T-shaped cross-section, with the larger diameter end located at the bottom and the smaller diameter end at the top. The second return spring is located in the larger diameter space within the through hole and is sleeved on the outside of the adjusting rod 4-18. The diameter of the second return spring is larger than the diameter of the smaller diameter end at the top of the through hole. During operation, by rotating the adjusting rod 4-18 to extend further into the through hole, the second return spring can be compressed, thereby adjusting the elastic force to meet different needs.

[0036] Furthermore, in this embodiment, a sealed door is provided on the frame 1, and a dehumidification mechanism is provided inside the frame 1 to dehumidify the printing workspace within the frame 1, ensuring the printing effect. Figure 2 As shown, the entire dehumidification mechanism is located at the rear of the frame 1, separated from the printing space. Specifically, the dehumidification mechanism includes a fan 9 located at the rear of the frame 1 and connected to the front working space. A dehumidifier 10 is connected to one side of the fan 9 to dehumidify the air in the suction working space. The outlet of the dehumidifier 10 is connected to an air outlet located at the rear of the frame 1. A heater 11 is installed at the air outlet. Since the temperature of the dehumidified air has not yet reached the required level, the heater 11 at the air outlet can blow airflow with a certain temperature into the front working space of the frame 1, further improving the printing effect.
