Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging equipment technology, specifically a plastic tray forming device for a powder injection cartoning machine. Background Technology

[0002] Powder injection medications typically come with a plastic tray inside the packaging (e.g., Figure 1 This type of plastic tray (with a structure) is used to provide support and separation protection for small packages of medicines such as injections or ampoules. It features several regularly arranged grooves, which can be square, round, or other shapes, to orderly place each individual small package of medicine.

[0003] Currently, the production of these plastic trays is mostly semi-automatic, requiring operators to manually remove trays from the tray-making machine. This high reliance on manual labor limits production efficiency and consistency. Furthermore, existing tray-making equipment generally lacks online detection capabilities, making it impossible to automatically identify and reject manufacturing defects such as insufficient groove depth in the plastic trays. These substandard products flowing into subsequent packaging stages may lead to unstable drug positioning, reduced packaging seals, or even product damage, affecting drug safety and overall packaging quality. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a plastic tray forming device for a powder injection cartoning machine.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A plastic tray forming device for a powder injection cartoning machine includes a film feeding mechanism, a film heating mechanism, a forming mechanism, a detection mechanism, a traction mechanism, a punching mechanism, and a discharge mechanism arranged in sequence. The detection mechanism includes a detection bracket, on which a detection cylinder is mounted. The output end of the detection cylinder is connected to a support mechanism. The support mechanism includes a first support plate and a second support plate arranged in parallel. The first support plate and the second support plate are fixedly connected by multiple columns. The lower second support plate is connected to multiple detection columns. The detection columns slide through the second support plate. A spring is sleeved on the upper part of the detection column. The upper part of the spring is fixedly connected to the first support plate. Multiple contact sensors are mounted on the lower surface of the first support plate. Each contact sensor corresponds to one detection column and is coaxially mounted with the detection column. The output end of the forming mechanism is provided with a traction belt, the other end of which extends to the punching mechanism. The traction belt is located at the lower part of the detection mechanism and can cooperate with the traction mechanism.

[0006] This invention incorporates a detection mechanism in the plastic tray molding and processing production line. This mechanism can detect whether the groove depth of the plastic tray is up to standard. Once a substandard product is detected, it will be fed back to the system so that the substandard product can be removed during subsequent output.

[0007] The film loading mechanism includes at least one set of film tensioning rollers and buffer rollers, as well as a film shortage detection device. The film is placed on the film tensioning rollers. When the film reaches the warning thickness, the film shortage detection device will detect it and display a warning. The buffer rollers play a buffering role, and the film tensioning rollers are tensioned using compressed air.

[0008] The film heating mechanism includes a heating plate 1 and a heating plate 2 arranged in parallel. Heating plate 1 is connected to a heating plate control cylinder 1, and heating plate 2 is connected to a heating plate control cylinder 2. After the film roll arrives at the heating station, heating plate control cylinder 1 and heating plate control cylinder 2 respectively control heating plate 1 and heating plate 2 to compress and heat the film.

[0009] The forming mechanism includes a first forming mold, a second forming mold, and multiple forming drive rods. The second forming mold is fixedly installed at the lower part. The output ends of the multiple forming drive rods are connected to the first forming mold, which is connected to compressed air. When the heated film reaches between the first and second forming molds, the forming drive rods drive the first forming mold to press the film together, and then the compressed air automatically starts, completing the forming of the plastic tray.

[0010] The traction mechanism includes a traction roller connected to a traction servo motor. The traction servo motor provides power to move the traction roller, transporting the molded plastic tray forward.

[0011] The blanking mechanism includes an upper blanking die and a lower blanking die. The upper blanking die is connected to an upper die cylinder, and the lower blanking die is connected to multiple lower die platform drive shafts at its lower part. The formed plastic tray enters the blanking station. The lower die platform drive shafts drive the lower die platform to rise, and the upper die cylinder drives the upper blanking die to cut the formed tray and separate it from the rolled film. The lower blanking die has a frame structure, with a discharge mechanism at its lower part.

[0012] The discharge mechanism includes a discharge conveyor belt one and a discharge conveyor belt two. A flap is installed at the end of discharge conveyor belt one, which connects discharge conveyor belt one and discharge conveyor belt two. Under normal circumstances, the flap is horizontally positioned, guiding the plastic trays on discharge conveyor belt one to discharge conveyor belt two. When defective products reach the end of discharge conveyor belt one, the system controls the flap to flip downwards, causing the defective products to fall off the production line.

[0013] The beneficial effects achieved by this utility model are: This invention features a high degree of automation, requires no manual operation, and can reduce costs and improve production efficiency. This invention features a detection mechanism that can detect the groove depth of each plastic tray, ensuring production quality and facilitating improvements in subsequent packaging quality and efficiency.

[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0017] Example: like Figure 2 , Figure 3 As shown, a plastic tray forming device for a powder injection cartoning machine includes a film feeding mechanism, a film heating mechanism, a forming mechanism, a detection mechanism, a traction mechanism, a punching mechanism, and a discharge mechanism arranged in sequence. The overall structure is supported by a base 6 and can cooperate with subsequent packaging operations.

[0018] The output end of the molding mechanism is provided with a traction belt 13, and the other end of the traction belt 13 extends to the punching mechanism. The traction belt 13 is located at the lower part of the detection mechanism and can cooperate with the traction mechanism to punch the molded plastic tray after it passes the detection.

[0019] The film loading mechanism includes at least one set of film tensioning rollers 2 and buffer rollers 3, and also includes a film shortage detection device 4. The film roll is placed on the film tensioning rollers 2. When the film roll reaches the warning thickness, the film shortage detection device 4 detects this and displays a warning. The buffer rollers 3 act as a buffer, and the film tensioning rollers 2 are tensioned using compressed air. The film shortage detection device 4 determines whether the film roll is about to run out by detecting the thickness; it can use existing sensors or visual detection.

[0020] The film heating mechanism includes a first heating plate 8 and a second heating plate 9 arranged in parallel. A first heating plate control cylinder 5 is connected to the upper part of the first heating plate 8, and a second heating plate control cylinder 7 is connected to the second heating plate 9, thereby controlling the up-and-down movement of the first heating plate 8 and the second heating plate 9. After the film roll reaches the heating station, the first heating plate control cylinder 5 and the second heating plate control cylinder 7 respectively control the first heating plate 8 and the second heating plate 9 to compress and heat the film, making the film softer.

[0021] The molding mechanism includes a first molding mold 10, a second molding mold 11, and multiple molding drive rods 12. The second molding mold 11 is fixedly installed at the lower part. The output ends of the multiple molding drive rods 12 are connected to the first molding mold 10. The first molding mold 10 is connected to compressed air. Several evenly arranged air blowing holes are opened on the lower surface of the first molding mold 10. The shape of the second molding mold 11 matches the structure of the plastic tray and is provided with several mold grooves. The mold grooves correspond one-to-one with the air blowing holes. The air blowing holes blow the film into the second molding mold 11, thereby realizing blow molding and completing the molding of the plastic tray.

[0022] The detection mechanism includes a detection bracket 23, on which a detection cylinder 22 is mounted. The output end of the detection cylinder 22 is connected to a support mechanism. The support mechanism includes a first support plate 24 and a second support plate 25 arranged in parallel. The first support plate 24 and the second support plate 25 are fixedly connected by multiple columns 26. The lower second support plate 25 is connected to multiple detection columns 27, which slide through the second support plate 25. A spring 28 is sleeved on the upper part of the detection column 27, and the upper part of the spring 28 is fixedly connected to the first support plate 24. Multiple contact sensors are arranged on the lower surface of the first support plate 24. Each contact sensor corresponds to one of the detection columns 27 and is coaxially arranged with the detection columns 27. The contact sensors are existing contact sensors.

[0023] The testing agency can test whether the depth of the plastic tray groove 1 is qualified. Specifically, the detection column 27 moves down a fixed distance along with the second support plate 25 and the detection cylinder 22. The detection column 27 extends into the corresponding plastic tray groove 1 and contacts its bottom. If the depth of the groove 1 meets the standard, the detection column 27 will not slide relative to the second support plate 25. If the depth of the groove 1 is too shallow, the detection column 27 will slide up relative to the second support plate 25, thereby triggering the contact sensor at the bottom of the first support plate 24. The contact sensor feeds back the signal to the system to mark the plastic tray.

[0024] The detection columns 27 are arranged in a row, and the number of detection columns 27 in a row is the same as the number of grooves 1 in the plastic tray. Each row of grooves 1 is detected at a time.

[0025] The traction mechanism includes a traction roller 14, which is connected to a traction servo motor. The traction servo motor provides power to move the traction roller 14, which, in conjunction with the traction belt 13, transports the formed plastic tray to the punching mechanism.

[0026] The punching mechanism includes an upper punching die 16 and a lower punching die 17. The upper punching die 16 is connected to an upper die cylinder 15. The lower punching die 17 is mounted on a lower die platform. Multiple lower die platform drive shafts 18 are connected to the lower part of the lower die platform. The lower die platform drive shafts 18 are fixedly mounted on the upper part of the base 6. An upper die platform is fixedly connected to the lower die platform. The upper die cylinder 15 is fixedly mounted on the upper die platform, and its output end is connected to the upper punching die 16. The formed plastic tray enters the punching station. The lower die platform drive shafts 18 drive the lower die platform to rise, and the upper die cylinder 15 drives the upper punching die 16 to cut the formed tray and separate it from the rolled film. The lower punching die 17 has a frame structure. The punched plastic tray falls from inside the frame structure. A discharge mechanism is provided at the bottom of the lower punching die 17, and the plastic tray falls into the discharge mechanism.

[0027] The discharge mechanism includes a first discharge conveyor belt 19 and a second discharge conveyor belt 21. A flap 20 is provided at the tail end of the first discharge conveyor belt 19, which connects the first discharge conveyor belt 19 and the second discharge conveyor belt 21. The flap 20 is rotatably connected to the tail end of the first discharge conveyor belt 19 and is connected to a tilting power mechanism, which drives the flap 20 to rotate, either horizontally or vertically.

[0028] Under normal circumstances, the flap 20 is set horizontally, guiding the plastic trays on the discharge conveyor belt 19 to the discharge conveyor belt 21. When a defective product reaches the end of the discharge conveyor belt 19, the system controls the flap 20 to flip downwards, causing the defective product to fall off the production line. Specifically, the detection mechanism checks whether the depth of the groove 1 of the plastic tray is qualified. Once a defective product is detected, it is fed back to the system. The distance between the defective plastic tray and the end of the discharge conveyor belt 19 is fixed. The system can determine the time it takes for the defective plastic tray to reach the end of the discharge conveyor belt 19 by calculating the number of defective products. When it arrives, the system controls the flipping power mechanism to drive the flap 20 to rotate downwards, causing the defective product to fall to the bottom. After falling, the flap 20 returns to horizontal, reconnecting the discharge conveyor belt 19 and the discharge conveyor belt 21.
