Abstract
Description
Technical Field
[0001] This utility model relates to a packaging device, specifically a packaging device for disposable syringes, belonging to the field of syringe packaging technology. Background Technology
[0002] The packaging of medical device products includes sterile packaging of medical sterile products such as syringes. The packaging process generally involves placing the syringes in a relatively clean workshop, putting disposable medical sterile syringes into bags, sealing the bags with a heat sealer, and then packing them into cartons. The medical products inside the bags are sterile and do not require further sterilization; they can be used directly.
[0003] A packaging device for a medical device manufacturing workshop disclosed in Chinese Patent Application Publication CN215707650U uses a drive assembly to limit the packaging bag containing medical syringes on both sides, ensuring the parallelism of the sealing line of the packaging bag containing medical syringes. A pressing assembly presses the two corners of the packaging. In addition, the start of a fan blows air to the surface of the packaging bag through the main air duct and ventilation slot, keeping the packaging bag containing disposable sterile medical syringes flat, facilitating further sealing and improving the sealing quality.
[0004] In the above patented solutions, the two corners of the packaging bag can be pressed by the pressing component. However, the support rod needs to be manually disengaged from the slot on the support block before the corners of the packaging can be pressed. After pressing, the support rod needs to be placed back into the slot on the support block before the next pressing can be performed. This increases the number of operation steps and time, and reduces production efficiency.
[0005] Therefore, a packaging device for disposable syringes is proposed here. Utility Model Content
[0006] This invention proposes a packaging device for disposable syringes, which can automatically drive a pressure plate to press the corners of the syringe packaging bag, thereby improving production efficiency.
[0007] This utility model is achieved through the following technical solution: a packaging device for disposable syringes, including a packaging table, a limiting component on the packaging table, and a pressing component on the limiting component.
[0008] The limiting component includes a movable groove formed on the packaging platform and a second rotary motor fixed on one side of the packaging platform. The output shaft end of the second rotary motor passes through the packaging platform and is fixed with a bidirectional threaded rod. The end of the bidirectional threaded rod away from the second rotary motor is rotatably connected to the inner wall of the movable groove. The outer surface of the bidirectional threaded rod is threaded with two L-shaped plates, and the outer surface of the L-shaped plates is slidably connected to the inner wall of the movable groove.
[0009] The clamping assembly includes a slide rod slidably connected to the inner wall of the upper hole of the L-shaped plate and two mounting plates fixed to the L-shaped plate. A pressure plate is fixed to the bottom end of the slide rod, and a spring is fixed to the upper surface of the pressure plate. The top end of the spring is fixed to the bottom surface of the L-shaped plate. The spring is sleeved on the outer surface of the slide rod. A toothed groove is opened on the side of the slide rod near the mounting plate. A first rotary motor is fixed to one side of the mounting plate. A rotating rod is fixed to the output end of the first rotary motor, and one end of the rotating rod is rotatably connected to the inner side of the mounting plate. A turntable is fixed to the outer surface of the rotating rod, and multiple toothed blocks are fixed to the outer surface of the turntable, and the toothed blocks mesh with the toothed groove.
[0010] Furthermore, a limiting rod is fixed to the upper surface of the pressure plate, and the top end of the limiting rod extends through to the top of the L-shaped plate.
[0011] Furthermore, a fixing block is fixed to the top of the slide bar, and sensors are installed on the adjacent sides of the two L-shaped plates.
[0012] Furthermore, a guide rod is fixed to the inner wall of the movable groove, and the inner wall of the hole on the L-shaped plate is slidably connected to the outer surface of the guide rod.
[0013] Furthermore, a through groove is provided on the packaging platform, and the outer surface of the output shaft of the second rotary motor is rotatably connected to the inner wall of the through groove.
[0014] Furthermore, the packaging platform is provided with ventilation openings, ventilation slots and mounting slots, and the ventilation openings, ventilation slots and mounting slots are connected to each other, and a fan is fixed to the inner bottom wall of the mounting slot.
[0015] Furthermore, a filter screen is fixed to the inner wall of the mounting groove, and the filter screen is located above the fan.
[0016] This utility model provides a packaging device for disposable syringes, which has the following beneficial effects:
[0017] 1. The packaging equipment for disposable syringes can drive a bidirectional threaded rod to rotate by starting a second rotary motor. The bidirectional threaded rod can drive two L-shaped plates to move closer to each other. When the sensor on the L-shaped plate contacts the side of the packaging bag containing the medical syringe, the second rotary motor stops working. The L-shaped plate can then limit the packaging bag containing the medical syringe, thereby ensuring the parallelism of the sealing line of the packaging bag containing the medical syringe.
[0018] 2. This packaging equipment for disposable syringes can rotate a turntable by starting a first rotary motor. The rotation of the turntable can drive the slide rod to move upward by meshing the toothed blocks on the turntable with the toothed grooves on the slide rod. At the same time, the pressure plate can compress the spring to generate elastic force. When the turntable drives the toothed blocks to disengage from the toothed grooves, the pressure plate will move downward under its own weight and the elastic force of the spring, thereby automatically pressing the corners of the syringe packaging bag.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.
[0029] Please see Figures 1-5The present invention proposes the following implementation scheme: a packaging device for disposable syringes, including a packaging platform 1, a limiting component 3 on the packaging platform 1, and a pressing component 2 on the limiting component 3.
[0030] Please refer to this carefully. Figure 3 The limiting component 3 includes a movable groove 304 opened on the packaging table 1 and a second rotary motor 301 fixed on one side of the packaging table 1. The output shaft end of the second rotary motor 301 passes through the packaging table 1 and is fixed with a bidirectional threaded rod 302. The end of the bidirectional threaded rod 302 away from the second rotary motor 301 is rotatably connected to the inner wall of the movable groove 304. The outer surface of the bidirectional threaded rod 302 is threadedly connected with two L-shaped plates 303, and the outer surface of the L-shaped plates 303 is slidably connected to the inner wall of the movable groove 304.
[0031] Sensors 9 are installed on the side of the two L-shaped plates 303 that are close to each other, and the sensors 9 are electrically connected to the second rotary motor 301.
[0032] The inner wall of the moving groove 304 is fixed with a guide rod 305, and the inner wall of the hole on the L-shaped plate 303 is slidably connected to the outer surface of the guide rod 305.
[0033] A through groove 306 is provided on the packaging table 1, and the outer surface of the output shaft of the second rotary motor 301 is rotatably connected to the inner wall of the through groove 306.
[0034] By starting the second rotary motor 301, the bidirectional threaded rod 302 can be driven to rotate. The bidirectional threaded rod 302 can drive the two L-shaped plates 303 to move closer to each other. When the sensor 9 on the L-shaped plate 303 contacts the side of the packaging bag containing the medical syringe, the second rotary motor 301 stops working. The L-shaped plate 303 can then limit the packaging bag containing the medical syringe, thereby ensuring the parallelism of the sealing line of the packaging bag containing the medical syringe.
[0035] Please refer to this carefully. Figure 2 and Figure 4 The clamping assembly 2 includes a slide rod 201 slidably connected to the inner wall of the upper hole of the L-shaped plate 303 and two mounting plates 210 fixed on the L-shaped plate 303. A pressure plate 203 is fixed to the bottom end of the slide rod 201, and a spring 202 is fixed to the upper surface of the pressure plate 203. The top end of the spring 202 is fixed to the bottom surface of the L-shaped plate 303. The spring 202 is sleeved on the outer surface of the slide rod 201, and a toothed groove 207 is provided on the side of the slide rod 201 near the mounting plate 210.
[0036] A first rotary motor 204 is fixed to one side of the mounting plate 210. A rotating rod 205 is fixed to the output end of the first rotary motor 204, and one end of the rotating rod 205 is rotatably connected to the inner side of the mounting plate 210. A turntable 206 is fixed to the outer surface of the rotating rod 205, and multiple tooth blocks 208 are fixed to the outer surface of the turntable 206. The tooth blocks 208 mesh with the tooth grooves 207. Each start of the first rotary motor 204 can only control the rotating rod 205 to rotate one revolution.
[0037] A limiting rod 211 is fixed on the upper surface of the pressure plate 203, and the top end of the limiting rod 211 extends through to the top of the L-shaped plate 303.
[0038] A fixing block 209 is fixed to the top of the slide bar 201. When the pressure plate 203 contacts the packaging table 1, the fixing block 209 will not contact the turntable 206 and the toothed block 208.
[0039] By starting the first rotary motor 204, the turntable 206 can be rotated via the rotating rod 205. Through the meshing of the toothed block 208 on the turntable 206 with the toothed groove 207 on the slide rod 201, the rotation of the turntable 206 can drive the slide rod 201 to move upward. At the same time, the pressure plate 203 can squeeze the spring 202 to generate elastic force. When the turntable 206 drives the toothed block 208 to disengage from the toothed groove 207, the pressure plate 203 will move downward under its own weight and the elastic force of the spring 202, thereby automatically pressing the corners of the syringe packaging bag.
[0040] Please refer to this carefully. Figure 5 The packaging table 1 is provided with ventilation openings 4, ventilation slots 5 and mounting slots 6, and the ventilation openings 4, ventilation slots 5 and mounting slots 6 are connected. There are multiple ventilation openings 4, and a fan 7 is fixed to the inner bottom wall of the mounting slot 6.
[0041] A filter screen 8 is fixed to the inner wall of the mounting slot 6, and the filter screen 8 is located above the fan 7.
[0042] When the fan 7 is turned on, air is blown through the ventilation slot 5 and the ventilation port 4 to the surface of the packaging bag, so that the packaging bag containing the disposable medical sterile syringe remains flat and facilitates further sealing.
[0043] In use, the second rotary motor 301 is activated to drive the bidirectional threaded rod 302 to rotate. The bidirectional threaded rod 302 drives the two L-shaped plates 303 to move closer to each other. When the sensor 9 on the L-shaped plate 303 contacts the side of the packaging bag containing the medical syringe, the second rotary motor 301 stops working. The L-shaped plate 303 can then limit the packaging bag containing the medical syringe, thereby ensuring the parallelism of the sealing line of the packaging bag containing the medical syringe.
[0044] Then, by starting the first rotary motor 204, the turntable 206 is driven to rotate via the rotating rod 205. Through the meshing of the toothed block 208 on the turntable 206 with the toothed groove 207 on the slide rod 201, the rotation of the turntable 206 can drive the slide rod 201 to move upward. At the same time, the pressure plate 203 can squeeze the spring 202 to generate elastic force. When the turntable 206 drives the toothed block 208 to disengage from the toothed groove 207, the pressure plate 203 will move downward under its own weight and the elastic force of the spring 202, thereby automatically pressing the corners of the syringe packaging bag. Finally, the blower 7 is started to blow air. The air from the blower 7 will be blown to the surface of the packaging bag through the ventilation slot 5 and the ventilation port 4, so that the packaging bag containing the disposable medical sterile syringe remains flat, which is convenient for further sealing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
