Description

Technical Field

[0001] This utility model relates to the technical field of rubber stopper production, and in particular to automatic rubber stopper quality testing equipment. Background Technology

[0002] Rubber stoppers are widely used in pharmaceutical packaging. Since drug safety directly threatens patients' health and lives, and rubber stoppers are the packaging material that comes into direct contact with the drugs, major pharmaceutical companies have very high quality requirements for rubber stoppers, some even requiring them to be washable. During the rubber stopper production process, defects such as polygons, cuts, collapsed corners, deformation, breakage, discoloration, white spots, dirt, foreign matter, and hair are unavoidable. To ensure the quality of rubber stoppers, manufacturers need to conduct comprehensive inspections of their appearance, shape, size, and color difference. Existing technology announcement CN221816760U proposes a visual inspection device for rubber stopper quality. It includes a conveying mechanism and an inspection mechanism. The conveying mechanism transports the rubber stoppers, and the inspection mechanism inspects the rubber stoppers on the conveying mechanism and generates inspection results. The inspection mechanism includes inspection components, including a top inspection camera and a side inspection camera, both located above the conveying mechanism and used for inspecting the rubber stoppers. Multiple detection components are used to inspect the rubber stoppers from all sides, eliminating the need to rotate the stoppers to change their orientation towards the detection components, thus improving sorting efficiency. However, the output of the rubber stoppers is unstable when arranged by a vibratory feeder. This can lead to uneven spacing between the output stoppers, or even disordered arrangement, exceeding the allowable error range and affecting subsequent inspection of the stoppers. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an automatic rubber stopper quality inspection device with a simple structure that can effectively organize rubber stoppers, making the output of rubber stoppers stable and orderly arranged, and improving the efficiency of rubber stopper organization and inspection.

[0004] This utility model discloses an automatic rubber stopper quality inspection device, comprising a rubber stopper quality inspector, a conveyor belt, a feeding component, an adjusting component, and a supporting component. The rubber stopper quality inspector is mounted on the conveyor belt, which has raised strips on its outer surface. The bottom of the conveyor belt is mounted on the supporting component. The feeding component is mounted on the upper left side of the conveyor belt, and the adjusting component is mounted on the right side of the feeding component. Rubber stoppers are added to the feeding component and fall down one by one onto the upper surface of the conveyor belt. The conveyor belt moves the rubber stoppers, and the adjusting component adjusts the rubber stoppers to the same state, facilitating subsequent inspection. The conveyor belt then carries the rubber stoppers into the rubber stopper quality inspector for inspection, determining whether the rubber stoppers are qualified.

[0005] Preferably, the feeding component includes two support frames, a feeding cylinder, multiple partitions, a discharge head, and a distribution assembly. The feeding cylinder is located above the left side of the conveyor belt. Support frames are fixedly installed on the front and rear side walls of the feeding cylinder. The lower ends of the support frames are bolted to the front and rear side walls of the conveyor belt. Multiple partitions are installed inside the feeding cylinder, and multiple discharge holes are staggered on the partitions. The discharge head is installed at the bottom of the feeding cylinder. Rubber plugs are added into the feeding cylinder and flow between the partitions through the discharge holes, causing the rubber plugs to fall down gradually and sequentially through the discharge head. This ensures that a certain number of rubber plugs fall onto the surface of the conveyor belt and that the rubber plugs are separated in an orderly and evenly spaced manner, facilitating subsequent inspection.

[0006] Preferably, the material distribution assembly includes a bracket, a geared motor, a rotating shaft, and multiple sets of levers. The rear end of the bracket is bolted to the upper end of the rear side wall of the feed cylinder. The geared motor is mounted on the top of the bracket. The output end of the geared motor is connected to the rotating shaft. The rotating shaft rotates through the middle of multiple partitions. Multiple sets of levers are installed on the outer wall of the rotating shaft, and the levers are located above the partitions. When the geared motor is started, it drives the rotating shaft to rotate. The rotating shaft drives the levers to rotate slowly, pushing the rubber plugs on the top of the partitions, separating each rubber plug, and allowing them to drain one by one.

[0007] Preferably, it also includes a column, a feeding turntable, and a fixing plate. The column is installed on the outer left side of the feeding head, and the feeding turntable is coaxially rotatably installed at the bottom of the column. The upper surface of the feeding turntable is in close contact with the bottom of the feeding head. The feeding turntable has multiple feeding holes of different sizes. A boss is provided at the center of the top of the feeding turntable. A limiting cylinder is installed at the lower end of the column, and the boss is located inside the limiting cylinder. A locking screw is provided on the outer wall of the limiting cylinder. According to the size of the rubber plug, the feeding turntable is rotated on the column to align the corresponding feeding hole with the output end of the feeding head. The locking screw is tightened to fix the feeding turntable, so that the rubber plugs are fed in sequence.

[0008] Preferably, the adjusting components include two fixed plates, two threaded rods, two connecting plates, two sets of guide rods, two adjusting plates, and two adjusting needle rods. The fixed plates are installed on the right side wall of the support frame. The threaded rods are screwed into the middle of the fixed plates, and the outer ends of the threaded rods are rotatably connected to the connecting plates. The left and right ends of the connecting plates are symmetrically installed with respect to the threaded rods, and are slidably installed on the fixed plates and connected to the adjusting plates. The threaded rods are rotatably connected to the middle of the adjusting plates, and the adjusting needle rods are installed at an angle on the right side of the adjusting plates. Rotating the threaded rods moves them on the fixed plates, adjusting the distance between the adjusting plates and the adjusting needle rod brackets. When the conveyor belt moves the rubber plugs and they come into contact with the adjusting needle rods, the angled adjusting needle rods adjust the upper part of the rubber plugs, bringing the rubber plugs to the same state, which facilitates subsequent testing.

[0009] Preferably, the support components include multiple legs and multiple support pads. The multiple legs are respectively installed at the four bottom corners of the conveyor belt, and the support pads are installed at the four bottom corners of the rubber plug quality detector. The bottoms of the legs and support pads are located on the same plane. During equipment installation, the bottom of the equipment is supported by the legs and support pads to ensure the stability of the equipment during use.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the rubber plugs are added into the feeding component, and the rubber plugs fall down one by one in sequence, landing on the upper surface of the conveyor belt. The conveyor belt drives the rubber plugs to move, and the rubber plugs are adjusted to the same state by the adjusting component, which facilitates the subsequent inspection. The conveyor belt drives the rubber plugs into the rubber plug quality inspection instrument to inspect the rubber plugs and determine whether the rubber plugs are qualified.

[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0018] like Figures 1 to 5As shown, the rubber stopper quality inspector 1 is installed on the conveyor belt 2. The outer surface of the conveyor belt 2 is provided with raised strips 22. The feed cylinder 6 is located above the left side of the conveyor belt 2. Support frames 5 are fixedly installed on the front and rear side walls of the feed cylinder 6. The lower end of the support frame 5 is bolted to the front and rear side walls of the conveyor belt 2. Multiple partitions 7 are installed inside the feed cylinder 6. Multiple discharge holes are staggered on the partitions 7. The discharge head 8 is installed at the bottom of the feed cylinder 6. The rear end of the bracket 9 is bolted to the upper end of the rear side wall of the feed cylinder 6. The reduction motor 10 is installed at the top of the bracket 9. The output end of the reduction motor 10 is connected to a rotating shaft 11. The rotating shaft 11 rotates through the middle of the multiple partitions 7. Multiple sets of levers 12 are installed on the outer wall of the rotating shaft 11, located above the partitions 7. A column 13 is installed on the left outer wall of the discharge head 8. A discharge turntable 14 is coaxially mounted at the bottom of the column 13. The surface is in close contact with the bottom of the feeding head 8. The feeding turntable 14 has multiple feeding holes of different sizes. A boss is set at the center of the top of the feeding turntable 14. The limiting cylinder 15 is installed at the lower end of the column 13. The boss is located inside the limiting cylinder 15. A locking screw is set on the outer wall of the limiting cylinder 15. The fixing plate 16 is installed on the right side wall of the support frame 5. The threaded rod 17 is screwed into the middle of the fixing plate 16. The outer end of the threaded rod 17 is rotatably connected to the connecting plate 18. The left and right ends of the connecting plate 18 are symmetrically installed with guide rods 19 about the threaded rod 17. They are slidably installed on the fixing plate 16 and connected to the adjusting plate 20. The threaded rod 17 is rotatably connected to the middle of the adjusting plate 20. An adjusting needle rod 21 is installed obliquely on the right side of the adjusting plate 20. Multiple support legs 3 are installed at the bottom four corners of the conveyor belt 2. Support pads 4 are installed at the bottom four corners of the rubber plug quality detector 1. The bottoms of the support legs 3 and the support pads 4 are on the same plane.

[0019] During equipment installation, the bottom of the equipment is supported by support legs 3 and support pads 4 to ensure stability during use. Rubber plugs are added into the feed cylinder 6 and flow through the discharge holes between multiple partitions 7. The plugs then fall sequentially downwards through the discharge head 8, ensuring a sufficient number of plugs reach the conveyor belt 2 and that they are orderly and evenly spaced for easy subsequent inspection. The geared motor 10 is started, driving the rotating shaft 11 to rotate. The rotating shaft 11 then slowly rotates the lever 12, pushing the rubber plugs at the top of the partitions 7 and separating each plug. The process begins with discharging the rubber plugs one by one. Based on the size of the rubber plugs, the feeding turntable 14 is rotated on the column 13 to align the corresponding feeding holes with the output end of the feeding head 8. The locking bolts are then tightened to fix the feeding turntable 14, allowing the rubber plugs to be fed sequentially. The threaded rod 17 is rotated to move on the fixed plate 16, adjusting the distance between the adjusting plate 20 and the adjusting needle rod 21 bracket. As the conveyor belt 2 moves the rubber plugs and they come into contact with the adjusting needle rod 21, the tilted adjusting needle rod 21 adjusts the upper part of the rubber plugs, bringing them to the same state for easier subsequent testing.

[0020] like Figures 1 to 5As shown, the automatic rubber stopper quality detection device of this utility model, during operation, involves adding rubber stoppers into the feed cylinder 6, starting the reduction motor 10 to drive the rotating shaft 11 to rotate, and the rotating shaft 11 drives the lever 12 to rotate slowly, pushing the rubber stoppers at the top of the partition 7. The rubber stoppers flow through the discharge holes between multiple partitions 7, causing them to fall sequentially downwards through the discharge head 8, ensuring that the number of rubber stoppers falling onto the upper surface of the conveyor belt 2 is sufficient and that the rubber stoppers are orderly and evenly separated. Based on the size of the rubber stoppers, the lever 12 is then activated. The feeding turntable 14 rotates on the column 13, aligning the corresponding feeding holes with the output end of the feeding head 8. The locking bolts are tightened to fix the feeding turntable 14, allowing the rubber plugs to be fed in sequence. The threaded rod 17 is rotated to move on the fixed plate 16, adjusting the distance between the adjusting plate 20 and the adjusting needle rod 21 bracket. When the conveyor belt 2 moves the rubber plugs and they come into contact with the adjusting needle rod 21, the tilted adjusting needle rod 21 adjusts the upper part of the rubber plugs, bringing them to the same state, which facilitates subsequent testing.
