[0002] Pharmaceutical manufacturing is a highly rigorous and strictly regulated process, with each step directly impacting the safety and efficacy of the final product. Among the many quality control steps, metal detection is a crucial one. Its core objective is to ensure that the final product is free of any metallic foreign objects that could have originated from raw materials, equipment wear and tear, or the manufacturing process, thereby guaranteeing patient safety.
[0003] In actual production lines, the standard procedure for metal detection of pharmaceuticals is as follows: the product enters the detection station, is conveyed through the detection area of the metal detector, the equipment scans the product, and if no metal foreign object is detected, it is deemed qualified and the product continues to be conveyed along the production line. Once a metal signal is detected, the system will immediately trigger the rejection device, automatically removing the unqualified product from the main line. Currently, the metal detectors commonly equipped in production lines are mostly large-diameter models, mainly designed for large packaging such as large bags and boxes weighing around 25kg. When it is necessary to detect individual medicine bottles, a problem arises where the equipment and the product are incompatible. Medicine bottles are small and lightweight, and the detection process is usually arranged before capping. Uncapped medicine bottles have poor stability when conveyed on large detection equipment and are prone to tipping over during conveying and detection, resulting in drug spillage. This causes product loss, contaminates the production line, and affects cleanliness and continuous operation.
[0004] Therefore, how to design a metal detector specifically for medicine bottles that can ensure stable transport of medicine bottles and prevent tipping during the inspection process is a technical problem that has not yet been solved in the existing technology. Utility Model Content

[0028] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example
[0029] This embodiment provides a metal detector specifically designed for medicine bottles, such as... Figure 1-5 As shown, it includes: a frame 1, a control device 2, a drive structure, a conveyor chain 3, baffles 4, a metal detection device 5, a rejection pusher 6, and a collection box 7; wherein, the control device 2 is fixedly installed on the frame 1; the drive structure is fixedly installed on the frame 1 and can be started or stopped by the control device 2; the conveyor chain 3 can be driven by the drive structure to rotate cyclically on the frame 1; there are two baffles 4, which are respectively adjustablely installed on the frame 1, located on both sides of the conveyor chain 3; the metal detection device 5 is fixedly installed... Mounted on the frame 1 and covering the middle position of the conveyor chain plate 3, it is used to detect metal in passing medicine bottles; the metal detection device 5 is electrically connected to the control device 2 to realize the transmission of detection signals; the rejection push rod 6 is telescopically mounted on the frame 1, located at the end of the baffle 4, and can be controlled by the control device 2 to extend outward or retract inward relative to the frame 1; the collection box 7 is fixedly mounted on the other side of the frame 1 opposite to the rejection push rod 6, and is open towards the side of the rejection push rod 6.
[0030] When performing metal detection on medicine bottles, the distance between the two side baffles 4 is first adjusted to a suitable width according to the actual size of the bottle to be tested, so as to form a limiting channel that matches the bottle. After adjustment, the drive structure is started by the control device 2, which drives the conveyor chain plate 3 to rotate in a cycle. The medicine bottle is smoothly conveyed from the entry end of the conveyor chain plate 3. When it passes the metal detection device 5, it will be scanned. If the detection result is qualified, the medicine bottle will continue to move forward with the conveyor chain plate 3 and enter the next production stage. If a metal foreign object is detected, the metal detection device 5 transmits an electrical signal to the control device 2. The control device 2 controls the rejection push rod 6 to extend outward and push the unqualified medicine bottle into the collection box 7, completing the automatic rejection. This embodiment is a metal detection machine specifically for medicine bottles. The adjustable spacing baffles 4 effectively limit and guide the medicine bottles, preventing them from tipping or deviating during the conveying and detection process, ensuring the continuous and stable operation of the detection process, and avoiding product loss and production line pollution caused by product spillage.
[0031] The control device and metal detection device used in this embodiment are both mature products in this technical field, and have been reliably and widely used in metal detection machines.
[0032] like Figure 1-2 As shown, the baffle 4 is installed on both sides of the conveyor chain plate 3 in an adjustable position via an adjustment structure; the adjustment structure includes a mounting base 41, a first mounting rod 42, an adjusting clamp 43, and a second mounting rod 44; wherein, there are at least two mounting bases 41, which are fixedly installed on the frame 1; there are at least two first mounting rods 42, whose bottom ends are fixedly installed on the mounting base 41; there are at least two adjusting clamps 43, one end of which is fixedly installed on the top end of the first mounting rod 42; there are at least two second mounting rods 44, one end of which is movably installed on the other end of the adjusting clamp 43, and the other end is fixedly connected to the baffle 4.
[0033] like Figure 2As shown, it also includes a clamping plate 45, a movable through hole 46, a mounting through hole 47, a threaded through hole 48, and a clamping bolt; wherein, there are two clamping plates 45, which are formed vertically opposite to each other at the other end of the adjusting clamp 43; the movable through hole 46 is formed between the two clamping plates 45, and the second mounting rod 44 is movably installed in the movable through hole 46; the mounting through hole 47 is opened on one of the clamping plates 45; the threaded through hole 48 is opened on the other clamping plate 45 at a position vertically opposite to the mounting through hole 47; after the clamping bolt passes through the mounting through hole 47, it is screwed into the threaded through hole 48, so that the two clamping plates 45 move toward each other, thereby movably installing the second mounting rod 44 on the adjusting clamp 43. When the position of the baffle 4 needs to be adjusted, first loosen the clamping bolts outward to release the clamping of the second mounting rod 44 by the two clamping plates 45; then move the second mounting rod 44 along the movable through hole 46, which will move the baffle 4 fixed thereto to the desired position; finally, tighten the clamping bolts inward to clamp the second mounting rod 44 by the two clamping plates 45, thereby completing the adjustment and fixation of the position of the baffle 4.
[0034] like Figure 3-4 As shown, the rejection push rod 6 includes a cylinder 61 and a push block 63; wherein, the cylinder 61 is fixedly mounted on the frame 1 and electrically connected to the control device 2, and has a retractable piston rod 62; the push block 63 is fixedly mounted on the free end of the piston rod 62 and can be driven by the piston rod 62 to extend outward or retract inward.
[0035] The pusher block 63 has an arc-shaped limiting surface 64 formed on the side facing the collection box 7 and away from the baffle 4. The arc-shaped limiting surface 64 can fit against the side wall of the medicine bottle, forming a stable limit and guide, ensuring that the medicine bottle is pushed away smoothly, and avoiding rolling or deviation due to the continuous movement of the conveyor chain plate 3, which would lead to rejection failure.
[0036] The driving structure includes a driving device 8, a first rotating shaft 81, a second rotating shaft 82, and a toothed groove. The driving device 8 has a driving shaft, fixedly mounted on the frame 1. The first rotating shaft 81 is rotatably mounted at one end of the frame 1, with a first driving sprocket fitted in the middle. The second rotating shaft 82 is rotatably mounted at the other end of the frame 1, with a second driving sprocket fitted in the middle. The toothed groove is formed on the inner side of the conveyor chain plate 3, allowing the conveyor chain plate 3 to mesh and drive with the first driving sprocket and the second driving sprocket. The driving shaft of the driving device 8 is connected to the first rotating shaft 81, driving the first rotating shaft 81 to rotate. Furthermore, through the meshing of the first driving sprocket, the conveyor chain plate 3, and the second driving sprocket, the conveyor chain plate 3 is driven to rotate cyclically on the frame 1.
[0037] It also includes a first drive pulley, a second drive pulley, and a transmission belt; wherein, the first drive pulley is mounted on the drive shaft; the second drive pulley is mounted on the first rotating shaft 81; the transmission belt is sleeved and mounted on the first drive pulley and the second drive pulley; the drive device 8 drives the drive shaft to rotate the first drive pulley, and drives the second drive pulley to rotate through the transmission belt, thereby driving the first rotating shaft 81 to rotate.
[0038] like Figure 5 As shown, the system also includes support rollers 84, at least two of which are rotatably mounted on the frame 1 and supported below the conveyor chain plate 3. These rollers are in rolling contact with the conveyor chain plate 3 and are located close to the first rotating shaft 81 and the second rotating shaft 82, respectively. The support rollers 84 provide rolling support for the conveyor chain plate 3, preventing it from sagging or vibrating due to excessive span, ensuring smooth operation of the conveyor chain plate 3, and reducing wear.
[0039] It also includes an alarm light 9, which is fixedly mounted on the frame 1 and electrically connected to the control device 2. When the metal detection device 5 detects metal inside the medicine bottle, the control device 2 will simultaneously control the alarm light 9 to sound an alarm, alerting the staff.
[0040] At the four corners of the bottom of the frame 1, height-adjustable support feet 11 are installed. When the ground is uneven, the frame 1 can be leveled and stably fixed by adjusting the height of each support foot 11.
[0041] This embodiment describes a metal detector specifically designed for medicine bottles. The method of use is as follows: When performing metal detection on a medicine bottle, first, according to the actual size of the bottle to be tested, loosen the clamping bolts outwards to release the clamping of the second mounting rod 44 by the two clamping plates 45. Then, move the second mounting rod 44 along the movable through hole 46 to adjust the distance between the two side baffles 4 to a suitable width, forming a limiting channel matching the medicine bottle. Finally, tighten the clamping bolts inwards to clamp and fix the second mounting rod 44 by the two clamping plates 45, thereby completing the adjustment and fixing of the baffle 4 position. After adjustment, the drive device 8 is started by the control device 2. The drive shaft of the drive device 8 drives the first drive pulley to rotate, which in turn drives the second drive pulley to rotate via the transmission belt, and drives the first rotating shaft 81 to rotate. Then, through the meshing of the first drive sprocket, the conveyor chain plate 3, and the second drive sprocket, the conveyor chain plate 3 rotates cyclically on the frame 1. The medicine bottle is smoothly conveyed from the inlet of the conveyor chain 3. When it passes the metal detection device 5, it will be scanned. If the detection result is qualified, the medicine bottle will continue to move forward with the conveyor chain 3 and enter the next production stage. If a metal foreign object is detected, the metal detection device 5 will transmit an electrical signal to the control device 2. The control device 2 will control the cylinder 61 to drive the pusher 63 to extend outward and push the unqualified medicine bottle into the collection box 7, completing the automatic rejection. At the same time, the control device 2 will synchronously control the alarm light 9 to sound an alarm to remind the staff.
[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
