Description

Technical Field

[0001] This utility model relates to the field of nasal spray production technology, and in particular to a nasal spray filling and capping device. Background Technology

[0002] In the production and processing of nasal sprays, the finished nasal spray needs to be filled into packaging cans by a filling device, and then capped and sealed by a capping device. Therefore, this process needs to be completed by a nasal spray filling and capping device.

[0003] Existing nasal spray filling and capping devices typically use a push rod to directly and rigidly compress the cap, which may cause the cap to crack when squeezed between the cap and the nasal spray can. According to the content of Chinese utility model patent publication number CN219838734U, the filling head in the filling assembly is exposed to the outside environment for a long time during filling, and its surface is prone to adhering to dust, impurities and other contaminants. These contaminants entering the can will contaminate the nasal spray and affect its effectiveness, which urgently needs to be improved.

[0004] To address the aforementioned technical deficiencies, a solution is proposed. During filling, the lifting block moves the toothed plate downwards, causing the gear meshing with the toothed plate to rotate the rotating rod. The rotating rod, through a bevel gear transmission assembly, drives the bidirectional lead screw inside the guide rail to rotate. This allows two moving blocks threadedly connected to the bidirectional lead screw to move towards each other under the limiting action of the limiting rod. This causes the hinge rod to rotate and pull the two protective shells away from each other, releasing the sealing protection of the filling head. When the filling head completes one filling cycle and moves upwards to reset, the gear drives the bidirectional lead screw to rotate in the opposite direction, causing the hinge rod to push the protective shells back to their original position. This closes the two protective shells, sealing and protecting the filling part of the filling head, preventing external dust, impurities, and other contaminants from contaminating the filling port. Simultaneously, the ultraviolet sterilization lamp installed inside the protective shell can sterilize and disinfect the filling head when the protective shell is closed, ensuring the purity and lack of contamination of the filling raw materials.

A mounting frame is fixedly mounted on the support frame, and a guide rail is fixedly mounted on the mounting frame. A bidirectional lead screw is rotatably mounted inside the guide rail. Two opposing moving blocks are threadedly connected to the bidirectional lead screw. Protective shells are provided on both sides of the filling head. Ultraviolet sterilization lamps are installed on the inner walls of the protective shells. Fixed blocks are fixedly mounted on the protective shells.

[0008] Preferably, the material conveying assembly includes a servo motor mounted on a processing table, a turntable connected to the output shaft of the servo motor, a limit groove formed at equal angles on the outer ring of the turntable, a limit plate attached to one side of the turntable, the limit plates being distributed in a semi-enclosed manner on the outer ring of the turntable, and the loading conveyor belt and the unloading conveyor belt attached to the bottom of the turntable.

[0009] Preferably, the fixed frame has a lifting groove and a first slot that are slidably connected to the lifting block and the toothed plate, and a second slot that is slidably connected to the connecting frame.

[0010] Preferably, a limit rod is fixedly installed inside the guide rail on one side of the bidirectional lead screw, and the moving block is slidably connected to the limit rod.

[0011] Preferably, the capping mechanism includes a support base fixedly mounted on the processing table, a conveyor frame mounted on the support base, and a conveyor belt disposed inside the conveyor frame.

[0012] Preferably, a bracket is fixedly installed on the conveyor frame, a second cylinder is installed on the bracket, a telescopic cavity is opened in the output rod of the second cylinder, a slider is slidably arranged in the telescopic cavity, and a guide rod is fixedly connected to the bottom of the slider.

[0013] Preferably, the guide rod slides through the telescopic cavity and is fixedly connected to the pressure block, a spring is sleeved on the guide rod and disposed between the pressure block and the output rod of the second cylinder, and a stop bar is installed on the conveyor frame.

[0014] Preferably, a feeding frame is fixedly installed at one end of the conveyor frame, a rotating shaft is fixedly installed inside the feeding frame, a baffle is rotatably installed on the rotating shaft, an iron block is fixedly installed at the bottom of the baffle away from the rotating shaft, and a magnetic block that is magnetically connected to the iron block is installed inside the feeding frame.

[0015] The beneficial effects of this utility model are: This invention utilizes a lifting block to move a toothed plate downwards during filling, causing a gear meshing with the toothed plate to rotate a rotating rod. The rotating rod, through a bevel gear transmission assembly, drives a bidirectional lead screw within the guide rail to rotate. This allows two moving blocks threadedly connected to the bidirectional lead screw to move towards each other under the limiting action of a limiting rod. This causes the hinge rod to rotate and pull the two protective shells away from each other, releasing the sealing protection of the filling head. When the filling head completes one filling cycle and moves upwards to reset, the gear drives the bidirectional lead screw to rotate in the opposite direction, causing the hinge rod to push the protective shells back to their original position. This closes the two protective shells together, sealing and protecting the filling part of the filling head, preventing external dust, impurities, and other contaminants from contaminating the filling port. Simultaneously, an ultraviolet sterilization lamp installed inside the protective shell can sterilize and disinfect the filling head when the protective shell is closed, ensuring the purity and lack of contamination of the filling raw materials. This invention uses a second cylinder to move a pressure block downwards and press down on the lid. At this time, the baffle is under pressure and rotates under the action of the rotating shaft, causing the feeding rack to gradually open. The lid is then pressed down onto the can opening and is clamped and fixed, thus covering the can. Through the setting of the telescopic cavity, slider, guide rod and spring, the pressure block can be buffered during the pressing connection between the lid and the can, avoiding the pressure block from directly and rigidly pressing the lid and the can, which would cause damage to both. This improves the safety and effectiveness of the device. After the baffle completes one covering operation, the iron block at one end of the baffle rotates and resets under its own weight until the iron block is magnetically connected to the magnetic block on the feeding rack, facilitating the next covering operation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: The application background of this utility model is based on the filling device filling finished nasal spray into packaging cans, and the capping device capping and sealing the filled nasal spray. The technical solution of this utility model is to solve the problem that dust and impurities are easily attached to the surface of the filling head in the filling component during filling, causing contamination to the nasal spray. Please see Figures 1-8 As shown, this embodiment is a nasal spray filling and capping device, including a processing table 1, a feeding conveyor belt 2, a discharging conveyor belt 3, a material conveying component 4, and a filling component 5; Reference Figure 2 As shown, the material conveying assembly 4 includes a servo motor 43 mounted on the processing table 1. A turntable 41 is connected to the output shaft of the servo motor 43. Limiting grooves 42 are opened at equal angles on the outer ring of the turntable 41. A limiting disk 44 is attached to one side of the turntable 41. The limiting disks 44 are distributed in a semi-enclosed manner on the outer ring of the turntable 41. The feeding conveyor belt 2 and the unloading conveyor belt 3 are attached to the bottom of the turntable 41. The cans for filling nasal spray are placed on the feeding conveyor belt 2 in sequence for conveying. When the cans are conveyed to the turntable 41, they are blocked by the limiting disks 44 and are locked in the limiting grooves 42 in sequence. Then, the servo motor 43 drives the turntable 41 to rotate. Reference Figure 3 As shown, the filling assembly 5 includes a storage tank 51. A support frame 53 for supporting the storage tank 51 is fixedly installed on the processing table 1. A filling head 54 is provided on one side of the storage tank 51. An injection pipe 52 is connected to the storage tank 51. A hose 55 is connected between the filling head 54 and the storage tank 51. When the tank rotates to below the filling head 54, the filling head 54 descends and fills the tank with sprayed medicine. Reference Figures 4-6As shown, a protective mechanism 6 is provided on the support frame 53. The protective mechanism 6 includes a fixed frame 61 fixedly mounted on the support frame 53. A first cylinder 62 is mounted on the fixed frame 61. The output rod of the first cylinder 62 slides through the fixed frame 61 and is connected to a lifting plate 63. Lifting blocks 64 are fixedly mounted at both ends of the lifting plate 63. Toothed plates 65 are fixedly mounted on the lifting blocks 64. A connecting frame 68 fixedly mounted on the filling head 54 and fixedly connected to the lifting blocks 64 is provided. The fixed frame 61 has a lifting groove 66 and a first slot 67 that slides through the lifting blocks 64 and the toothed plates 65. The fixed frame 61 has a second slot 69 that slides through the connecting frame 68. The first cylinder 62 passes through the lifting plate 63, the lifting blocks 64 and the toothed plates 65. The connecting frame 68 drives the filling head 54 to descend and fill the tank with spray agent. A mounting frame 610 is fixedly mounted on the support frame 53, and a guide rail 611 is fixedly mounted on the mounting frame 610. A bidirectional lead screw 612 is rotatably mounted inside the guide rail 611. Two opposing moving blocks 614 are threadedly connected to the bidirectional lead screw 612. A limit rod 613 is fixedly mounted inside the guide rail 611 on one side of the bidirectional lead screw 612. The moving blocks 614 are slidably connected to the limit rod 613. Protective shells 615 are provided on both sides of the filling head 54. An ultraviolet sterilization lamp 616 is installed on the inner wall of the protective shell 615. A fixing block 617 is fixedly mounted on the protective shell 615, and a hinge rod is hinged between the fixing block 617 and the moving block 614. 618. A mounting base 619 is fixedly mounted on the mounting bracket 610. A rotating rod 620 is rotatably mounted on the mounting base 619. One end of the rotating rod 620 is fixedly connected to a gear 622 that meshes with the toothed plate 65. The other end of the rotating rod 620 is connected to a bevel gear transmission assembly 621 that drives the bidirectional lead screw 612. When the lifting block 64 moves down along the lifting groove 66, it drives the toothed plate 65 to move down, causing the gear 622 that meshes with the toothed plate 65 to drive the rotating rod 620 to rotate. The rotating rod 620 drives the bidirectional lead screw 612 in the guide rail 611 to rotate through the bevel gear transmission assembly 621, so that the two moving blocks 614 that are threaded to the bidirectional lead screw 612 can move towards each other under the limiting action of the limiting rod 613. As the distance between the two protective shells 615 gradually increases, the hinge rod 618 rotates and pulls the protective shell 615 to move, thereby moving the two protective shells 615 away from each other and releasing the sealing protection of the filling head 54. When the filling head 54 returns to its original position after completing one filling cycle, the gear 622 drives the bidirectional lead screw 612 to rotate in the opposite direction, thereby causing the hinge rod 618 to push the protective shell 615 back to its original position. This causes the two protective shells 615 to close together and seal the filling part of the filling head 54, preventing external dust and impurities from contaminating the filling port. At the same time, the ultraviolet sterilization lamp 616 installed inside the protective shell 615 can also sterilize and disinfect the filling head 54 when the protective shell 615 is closed, ensuring that the filling raw materials are pure and uncontaminated. Example 2: Please refer to Figure 7 and Figure 8As shown, this embodiment is a nasal spray filling and capping device, including a capping mechanism 7. The capping mechanism 7 includes a support base 71 fixedly mounted on a processing table 1, a conveyor frame 72 mounted on the support base 71, a conveyor belt 73 disposed inside the conveyor frame 72, a bracket 74 fixedly mounted on the conveyor frame 72, a second cylinder 75 mounted on the bracket 74, a telescopic cavity 76 opened in the output rod of the second cylinder 75, a slider 77 slidably disposed in the telescopic cavity 76, a guide rod 78 fixedly connected to the bottom of the slider 77, the guide rod 78 slidably passes through the telescopic cavity 76 and is fixedly connected to a pressure block 710, and a sleeve is provided on the guide rod 78. A spring 79 is placed between the pressure block 710 and the output rod of the second cylinder 75. A baffle 711 is installed on the conveyor frame 72. A feeding frame 712 is fixedly installed at one end of the conveyor frame 72. A rotating shaft 714 is fixedly installed inside the feeding frame 712. A baffle 713 is rotatably installed on the rotating shaft 714. An iron block 715 is fixedly installed at the bottom of the end of the baffle 713 away from the rotating shaft 714. A magnetic block 716 is installed inside the feeding frame 712 and magnetically connected to the iron block 715. The conveyor belt 73 inside the conveyor frame 72 is used to transport the lid. The baffle 711 can limit the conveying position of the lid, so that the lid can be accurately transported. When the bottle body after filling is rotated to below the capping mechanism 7 by the turntable 41 and the two baffles 713 on the feeding rack 712, the second cylinder 75 drives the pressing block 710 to move down and press down the cap. At this time, the baffle 713 is under pressure and rotates under the action of the rotating shaft 714, causing the feeding rack 712 to gradually open. The cap is pressed down onto the mouth of the can and is pressed and fixed, thus capping the can. Through the setting of the telescopic cavity 76, the slider 77, the guide rod 78 and the spring 79, the pressing block 710 can be buffered during the process of squeezing the cap and the can body, avoiding The pressure block 710 directly and rigidly compresses the lid and the can, causing damage to both, thus improving the safety and effectiveness of the device. After the baffle 713 completes one capping operation, the iron block 715 at one end of the baffle 713 rotates and resets under its own weight until the iron block 715 is magnetically connected to the magnetic block 716 on the unloading rack 712, facilitating the next capping operation. The turntable 41 continues to rotate the can after the capping is completed. When it reaches the upper end of the unloading conveyor belt 3, since it is not blocked by the limit plate 44, the capped can will fall onto the unloading conveyor belt 3 for unloading.

[0020] As can be seen from Embodiment 1 and Embodiment 2, the cans for filling nasal spray are placed sequentially on the feeding conveyor belt 2 for conveying. When the cans are conveyed to the turntable 41, they are blocked by the limiting plate 44 and are sequentially locked in the limiting groove 42. Then, the servo motor 43 drives the turntable 41 to rotate. When the can rotates to below the filling head 54, the first cylinder 62 drives the filling head 54 to descend through the lifting plate 63, the lifting block 64 and the connecting frame 68 and fills the can with the spray medicine. When the lifting block 64 moves down along the lifting groove 66, it drives the toothed plate 65 down, causing the gear 622 meshing with the toothed plate 65 to drive the rotating rod 620 to rotate. The rotating rod 620 drives the bidirectional lead screw 612 in the guide rail 611 to rotate through the bevel gear transmission assembly 621, so that the two moving blocks 614 threadedly connected to the bidirectional lead screw 612 can move towards each other under the limiting action of the limiting rod 613. The distance between the two moving blocks 614 gradually increases, causing the hinge rod 618 to rotate and pull the protective shell 615 to move, thereby causing the two protective shells 615 to move away from each other. In addition to providing sealed protection for the filling head 54, when the filling head 54 moves upward and resets after completing one filling cycle, the gear 622 drives the bidirectional lead screw 612 to rotate in the opposite direction, thereby causing the hinge rod 618 to push the protective shell 615 to reset. This allows the two protective shells 615 to close together and seal the filling part of the filling head 54, preventing external dust and impurities from contaminating the filling port. At the same time, the ultraviolet sterilization lamp 616 installed inside the protective shell 615 can also sterilize and disinfect the filling head 54 when the protective shell 615 is closed, ensuring that the filling raw materials are pure and uncontaminated. The conveyor belt 73 inside the conveyor frame 72 is used to transport the caps. The baffle 711 restricts the conveying position of the caps, allowing them to be accurately transported to the two baffles 713 on the unloading frame 712. When the turntable 41 rotates the filled bottle to below the capping mechanism 7, the second cylinder 75 drives the pressing block 710 to move down and press down the cap. At this time, the baffle 713 is under pressure and rotates under the action of the rotating shaft 714, causing the unloading frame 712 to gradually open. The cap is then pressed down onto the can opening and is pressed and fixed, thus capping the can. Through the setting of the telescopic cavity 76, the slider 77, the guide rod 78, and the spring 79, the pressing block 710 squeezes the cap and the can. During the pressing process, the pressure block 710 can be buffered to avoid the pressure block 710 directly and rigidly pressing the lid and the can, which would cause damage to both. This improves the safety and effectiveness of the device. After the baffle 713 completes one capping operation, the iron block 715 at one end of the baffle 713 rotates and resets under its own weight until the iron block 715 is magnetically connected to the magnetic block 716 on the feeding rack 712, which facilitates the next capping operation. The turntable 41 continues to drive the can after the capping to rotate. When it reaches the upper end of the feeding conveyor belt 3, since it is not blocked by the limit plate 44, the capped can will fall onto the feeding conveyor belt 3 for feeding.

[0021] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
