Description

Technical Field

[0001] This utility model relates to the technical field of drug production and packaging, specifically to an aluminum foil sealing machine for drug preparation. Background Technology

[0002] In the pharmaceutical manufacturing process, aluminum foil sealing machines utilize technologies such as heat induction to tightly seal aluminum foil onto the bottle opening, achieving a good seal and preventing the medicine from becoming damp, oxidized, or contaminated by microorganisms. When using an aluminum foil sealing machine, the operator typically places the bottle to be sealed on a conveyor belt, which then transports it to a magnetic induction machine. After sealing, the bottle is transported away, and the next bottle to be sealed is transported to the machine, and this cycle continues. However, when manually placing the bottle, it is easy for it to misalign with the magnetic induction machine, affecting the sealing effect or even causing sealing failure.

[0003] In the existing technical solution, Chinese Patent No. CN 222647618 U discloses an automated aluminum foil sealing machine including two opposing first cylinders. Each first cylinder has a pressure plate fixed at the end of its telescopic rod. Driven by the first cylinder, the two pressure plates can clamp or release the bottles to be sealed on the conveyor belt from the left and right sides, thereby aligning the bottles with the magnetic sensor.

[0004] The shortcomings of the existing technical solutions are as follows: In actual drug production, pharmaceutical companies often need to simultaneously handle the sealing of multiple different types of medicine bottles to meet diverse drug packaging requirements. However, this automated aluminum foil sealing machine can only seal one type of medicine bottle at a time. Due to limitations in its pressure plate structure and adjustment mechanism, it cannot flexibly adapt to sealing medicine bottles of different diameters, heights, and other specifications simultaneously on the conveyor belt. Switching between bottle types requires re-adjustment and reconfiguration of the equipment, which not only significantly reduces production efficiency but also increases equipment setup and time costs. Utility Model Content

[0005] This invention provides an aluminum foil sealing machine for drug preparation, which can solve the problem that existing aluminum foil sealing machines cannot flexibly adapt to sealing of medicine bottles of different diameters, heights and other specifications on a conveyor belt at the same time.

[0006] A foil sealing machine for pharmaceutical preparation includes a sealing frame and a conveyor belt mounted on top of the sealing frame. A magnetic sensor is installed above the conveyor belt. Two sets of bottle position adjustment mechanisms are symmetrically distributed on both sides of the conveyor belt. Each bottle position adjustment mechanism includes a pressure plate, a movable block, a touch switch, and a telescopic rod. The telescopic rod is fixedly connected to the sealing frame, and the pressure plate is fixedly connected to the telescopic end of the telescopic rod. A slot is formed on the side of the pressure plate, and the movable block is slidably connected to the slot. The touch switch is fixedly located at the bottom of the slot. The telescopic rod is an electric push rod, which is fixedly connected to the sealing frame. The pressure plate is fixedly connected to the telescopic end of the electric push rod. A control terminal is installed on the sealing frame, and the magnetic sensor, touch switch, and electric push rod are all electrically connected to the control terminal.

[0007] As a further embodiment of this invention: a sliding groove is provided on the side of the slot, and a slider that slides in cooperation with the sliding groove is fixedly provided on the side of the movable block. The adjustment mechanism also includes a limiting block, which is fixedly provided at the opening of the sliding groove.

[0008] As a further embodiment of this utility model: the adjustment mechanism further includes a spring, the spring is disposed in the slot, one end of the spring abuts against the movable block, and the other end of the spring abuts against the bottom of the slot.

[0009] As a further embodiment of this utility model: a plurality of vertical guide rods arranged in a matrix are fixedly installed on the sealing machine frame, and a plurality of limiting slides that are slidably connected to the corresponding vertical guide rods are fixedly installed on the side of the magnetic sensor. The sealing machine frame is also provided with a height adjustment mechanism for adjusting the height of the magnetic sensor. The height adjustment mechanism includes a bracket, a vertical screw, and an adjustment slide. The bracket is fixedly connected to the sealing machine frame, the vertical screw is rotatably connected to the bracket, and the adjustment slide is fixedly connected to the sealing machine frame. The adjustment slide has a threaded hole that is threadedly connected to the vertical screw. The height adjustment mechanism also includes an adjustment motor, which is fixedly installed on the top of the bracket, and the output end of the adjustment motor is coaxially fixedly connected to the vertical screw. The height adjustment mechanism also includes a laser rangefinder sensor, which is fixedly installed on the side of the magnetic sensor. A control terminal is provided on the sealing machine frame, and the magnetic sensor, the touch switch, the telescopic rod, the laser rangefinder sensor, and the adjustment motor are all electrically connected to the control terminal.

[0010] The advantages of this utility model compared to the prior art are:

[0011] 1. Through two sets of symmetrically arranged bottle position adjustment mechanisms, in conjunction with the coordinated operation of electric push rods, pressure plates, movable blocks, and touch switches, the automatic adjustment and positioning of the medicine bottles can be achieved. Compared with traditional manual placement or simple mechanical positioning methods, the sealing machine in this embodiment can accurately push the medicine bottles to the center of the conveyor belt and align them directly below the magnetic sensor, greatly avoiding problems such as incomplete sealing and aluminum foil wrinkles caused by bottle position deviations. This ensures that the aluminum foil adheres tightly and evenly to the bottle mouth, significantly improving the accuracy and reliability of sealing, effectively reducing the defect rate, providing high-quality packaging protection for medicines, and strongly guaranteeing the safety of medicines during storage and transportation, preventing medicines from getting damp, oxidized, or contaminated by microorganisms.

[0012] 2. The bottle position adjustment mechanism of this aluminum foil sealing machine can automatically adapt to medicine bottles of different diameters. Regardless of the bottle diameter, the linkage mechanism of the moving block, pressure plate, and electric push rod can accurately adjust and position the bottle through contact and compression with the bottle, combined with feedback from the touch switch, without the need for manual adjustment of equipment parameters or replacement of parts. This feature allows pharmaceutical companies to easily handle sealing tasks for various bottle sizes during production, eliminating the need for frequent equipment adjustments or resets due to changes in bottle size. This greatly improves production flexibility and equipment versatility, significantly increases production efficiency, and reduces equipment setup and time costs.

[0021] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0022] First Embodiment

[0023] Please see Figures 1 to 4 As shown, an aluminum foil sealing machine for pharmaceutical preparation includes a sealing frame 1 and a conveyor belt 2 mounted on top of the sealing frame 1. A magnetic sensor 3 is positioned above the conveyor belt 2. Two sets of bottle position adjustment mechanisms 4 are symmetrically distributed on both sides of the conveyor belt 2 and located below the magnetic sensor 3. Each bottle position adjustment mechanism 4 includes a pressure plate 5, a movable block 6, a touch switch 7, and a telescopic rod 8. The telescopic rod 8 is fixedly connected to the sealing frame 1. The pressure plate 5 is fixedly connected to the telescopic end of the telescopic rod 8. A slot 9 is provided on the side of the pressure plate 5. The movable block 6 is slidably connected to the slot 9. The touch switch 7 is fixedly located at the bottom of the slot 9. The telescopic rod 8 is an electric push rod, which is fixedly connected to the sealing frame 1. The pressure plate 5 is fixedly connected to the telescopic end of the electric push rod. The sealing machine frame 1 is equipped with a control terminal, and the magnetic sensor 3, the touch switch 7 and the electric push rod are all electrically connected to the control terminal.

[0024] The operator places the medicine bottle to be sealed on conveyor belt 2, and the bottle moves forward under the drive of conveyor belt 2. When the medicine bottle enters between the two sets of bottle position adjustment mechanisms 4 symmetrically distributed on both sides of conveyor belt 2, the control terminal activates the electric push rod in advance. The telescopic end of the electric push rod begins to extend outward, driving the pressure plate 5 fixedly connected to it to move towards the medicine bottle. As the pressure plate 5 advances, the movable block 6 installed in the slot 9 on the side of the pressure plate 5 first contacts and abuts against the side of the medicine bottle, pushing and adjusting the medicine bottle to the center position of conveyor belt 2, so that the medicine bottle is accurately aligned directly below the magnetic sensor 3, preparing for the subsequent sealing process.

[0025] Next, the telescopic end of the electric push rod continues to extend outward. Since the medicine bottle is fixed in the center of the conveyor belt 2 and can no longer move laterally, under the pushing force of the pressure plate 5, the medicine bottle will squeeze the movable block 6. Under the pressure of the medicine bottle, the movable block 6 slides along the slot 9 on the side of the pressure plate 5 and finally presses the touch switch 7 set at the bottom of the slot 9. After the touch switch 7 is pressed, it generates an electrical signal, which is quickly transmitted to the control terminal on the sealing machine frame 1. After receiving the signal from the touch switch 7, the control terminal controls the telescopic end of the electric push rod to retract inward, driving the pressure plate 5 to quickly return to its initial position, thereby avoiding the pressure plate 5 from obstructing the subsequent sealing operation and the conveying of the medicine bottle.

[0026] Subsequently, the medicine bottle continues to move forward with conveyor belt 2 to below the magnetic sensor 3. After receiving the command from the control terminal, the magnetic sensor 3 starts and uses thermal induction technology to seal the aluminum foil at the mouth of the medicine bottle. After sealing, the medicine bottle leaves the sealing area with conveyor belt 2. Subsequent medicine bottles to be sealed repeat the above adjustment, positioning and sealing process to achieve continuous and efficient aluminum foil sealing operation for medicines.

[0027] It should be specifically explained that when the medicine bottle enters between the two sets of bottle position adjustment mechanisms 4 along with the conveyor belt 2, photoelectric sensors can be installed on the two opposing pressure plates 5, one as the transmitter and the other as the receiver. The transmitter continuously emits infrared or visible light, while the receiver receives the light emitted by the transmitter. When the medicine bottle enters between the two pressure plates 5 along with the conveyor belt 2, it blocks the light between the transmitter and receiver. The receiver cannot receive light or the intensity of the received light is weakened, triggering the internal circuit of the photoelectric sensor, generating an electrical signal, and transmitting this signal to the control terminal. After receiving the signal, the control terminal activates the electric push rod, causing the pressure plate 5 to begin moving to adjust the position of the medicine bottle.

[0028] Through the coordinated operation of two symmetrically arranged bottle position adjustment mechanisms 4, along with electric push rods, pressure plates 5, movable blocks 6, and touch switches 7, the automatic adjustment and positioning of the medicine bottles can be achieved. Compared with traditional manual placement or simple mechanical positioning methods, the sealing machine in this embodiment can accurately push the medicine bottles to the center of the conveyor belt 2 and align them directly below the magnetic sensor 3, greatly avoiding problems such as incomplete sealing and aluminum foil wrinkles caused by bottle position deviations. This ensures that the aluminum foil adheres tightly and evenly to the bottle mouth, significantly improving the accuracy and reliability of sealing, effectively reducing the defect rate, providing high-quality packaging protection for medicines, and strongly guaranteeing the safety of medicines during storage and transportation, preventing medicines from getting damp, oxidized, or contaminated by microorganisms.

[0029] The bottle position adjustment mechanism 4 of this aluminum foil sealing machine can automatically adapt to medicine bottles of different diameters. Regardless of the bottle diameter, the linkage mechanism of the movable block 6, pressure plate 5, and electric push rod can achieve precise adjustment and positioning of the bottle through contact and compression with the bottle, combined with the feedback of the touch switch 7, without the need for manual adjustment of equipment parameters or replacement of parts. This feature allows pharmaceutical companies to easily handle the sealing of various sizes of medicine bottles during production, without the need for frequent equipment debugging or reset due to changes in bottle size. This greatly improves production flexibility and equipment versatility, significantly increases production efficiency, and reduces equipment debugging and time costs.

[0030] Second Embodiment

[0031] Based on the first embodiment, a sliding groove 10 is provided on the side of the slot 9, and a slider 11 that slides in cooperation with the sliding groove 10 is fixedly provided on the side of the movable block 6. The adjustment mechanism also includes a limiting block 12, which is fixedly provided at the opening of the sliding groove 10. When the medicine bottle squeezes the movable block 6 and triggers the touch switch 7, the control terminal controls the electric push rod to drive the pressure plate 5 back to the initial position. Before subsequent medicine bottles enter the adjustment area, the movable block 6 is always within the normal working range constrained by the limiting block 12. The setting of the limiting block 12 avoids the failure of the bottle position adjustment mechanism 4 due to the accidental dislodgement of the movable block 6, ensuring the stability of the aluminum foil sealing machine during long-term continuous operation, reducing the probability of equipment failure, reducing maintenance costs and downtime, and improving overall production efficiency.

[0032] Third Embodiment

[0033] Based on the first embodiment, the adjustment mechanism further includes a spring 13, which is disposed within the slot 9. One end of the spring 13 abuts against the movable block 6, and the other end abuts against the bottom of the slot 9. When the medicine bottle presses against the movable block 6 to slide within the slot 9, the movable block 6 compresses the spring 13, which stores elastic potential energy. When the medicine bottle is accurately adjusted to the center position of the conveyor belt 2, the touch switch 7 is triggered. The control terminal controls the electric push rod to drive the pressure plate 5 back to its initial position, and the medicine bottle continues to move forward, leaving the area of ​​the bottle position adjustment mechanism 4. At this time, the spring 13 releases the previously stored elastic potential energy, pushing the movable block 6 to slide in the opposite direction along the slot 9, quickly resetting it to its initial position, preparing for the entry and position adjustment of the next medicine bottle to be sealed.

[0034] Fourth embodiment

[0035] Based on the first embodiment, the sealing machine frame 1 is fixedly provided with a plurality of vertical guide rods 14 arranged in a matrix, and the side of the magnetic sensor 3 is fixedly provided with a plurality of limiting slides 15 that are slidably connected to the corresponding vertical guide rods 14. The sealing machine frame 1 is also provided with a height adjustment mechanism 16 for adjusting the height of the magnetic sensor 3. The height adjustment mechanism 16 includes a bracket 17, a vertical screw 18, and an adjusting slide 19. The bracket 17 is fixedly connected to the sealing machine frame 1, the vertical screw 18 is rotatably connected to the bracket 17, and the adjusting slide 19 is fixedly connected to the sealing machine frame 1. The adjusting slide 19 has a screw hole that is threadedly connected to the vertical screw 18. The height adjustment mechanism 16 also includes an adjusting motor 20, which is fixedly provided on the top of the bracket 17, and the output end of the adjusting motor 20 is coaxially fixedly connected to the vertical screw 18. The height adjustment mechanism 16 also includes a laser rangefinder 21, which is fixedly mounted on the side of the magnetic sensor 3. A control terminal is provided on the sealing machine frame 1. The magnetic sensor 3, the touch switch 7, the telescopic rod 8, the laser rangefinder 21, and the adjustment motor 20 are all electrically connected to the control terminal.

[0036] When the medicine bottle moves along the conveyor belt 2 to below the laser rangefinder 21, the laser rangefinder 21 emits a laser beam towards the top of the medicine bottle and receives the reflected laser signal. By calculating the round-trip time of the laser, the distance between the top of the medicine bottle and the magnetic sensor 3 is accurately measured, and the data is transmitted to the control terminal in real time.

[0037] The control terminal analyzes and processes this data. When a difference is detected between the height of the medicine bottle and the preset height, the control adjustment motor 20 is activated. The adjustment motor 20 drives the vertical screw 18, which is coaxially fixed to it, to rotate. Since the adjustment slide 19 is threadedly engaged with the vertical screw 18 and fixed to the sealing frame 1, the rotation of the vertical screw 18 causes the adjustment slide 19 to move vertically. This, in turn, drives the magnetic sensor 3 to move up and down along the vertical guide rod 14 through the limit slide 15 until the magnetic sensor 3 reaches a suitable distance from the mouth of the medicine bottle.

[0038] Through the coordinated operation of the height adjustment mechanism 16 and the laser rangefinder sensor 21, the aluminum foil sealing machine is able to automatically adapt to medicine bottles of different heights. Whether it is a short or tall bottle, the equipment can automatically and accurately adjust the position of the magnetic sensor 3 according to the actual height of the medicine bottle, ensuring that the magnetic sensor 3 maintains the optimal distance from the bottle mouth during the sealing process, which greatly improves the stability and consistency of the sealing effect.

[0039] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be explained in conjunction with specific application scenarios:

[0040] The operator places the medicine bottle to be sealed on conveyor belt 2, and the bottle moves forward under the drive of conveyor belt 2. When the medicine bottle enters between the two sets of bottle position adjustment mechanisms 4 symmetrically distributed on both sides of conveyor belt 2, the control terminal activates the electric push rod in advance. The telescopic end of the electric push rod begins to extend outward, driving the pressure plate 5 fixedly connected to it to move towards the medicine bottle. As the pressure plate 5 advances, the movable block 6 installed in the slot 9 on the side of the pressure plate 5 first contacts and abuts against the side of the medicine bottle, pushing and adjusting the medicine bottle to the center position of conveyor belt 2, so that the medicine bottle is accurately aligned directly below the magnetic sensor 3, preparing for the subsequent sealing process.

[0041] Next, the telescopic end of the electric push rod continues to extend outward. Since the medicine bottle is fixed in the center of the conveyor belt 2 and can no longer move laterally, under the pushing force of the pressure plate 5, the medicine bottle will squeeze the movable block 6. Under the pressure of the medicine bottle, the movable block 6 slides along the slot 9 on the side of the pressure plate 5 and finally presses the touch switch 7 set at the bottom of the slot 9. After the touch switch 7 is pressed, it generates an electrical signal, which is quickly transmitted to the control terminal on the sealing machine frame 1. After receiving the signal from the touch switch 7, the control terminal controls the telescopic end of the electric push rod to retract inward, driving the pressure plate 5 to quickly return to its initial position, thereby avoiding the pressure plate 5 from obstructing the subsequent sealing operation and the conveying of the medicine bottle.

[0042] Subsequently, the medicine bottle continues to move forward with conveyor belt 2 to below the magnetic sensor 3. After receiving the command from the control terminal, the magnetic sensor 3 starts and uses thermal induction technology to seal the aluminum foil at the mouth of the medicine bottle. After sealing, the medicine bottle leaves the sealing area with conveyor belt 2. Subsequent medicine bottles to be sealed repeat the above adjustment, positioning and sealing process to achieve continuous and efficient aluminum foil sealing operation for medicines.

[0043] It should be specifically explained that when the medicine bottle enters between the two sets of bottle position adjustment mechanisms 4 along with the conveyor belt 2, photoelectric sensors can be installed on the two opposing pressure plates 5, one as the transmitter and the other as the receiver. The transmitter continuously emits infrared or visible light, while the receiver receives the light emitted by the transmitter. When the medicine bottle enters between the two pressure plates 5 along with the conveyor belt 2, it blocks the light between the transmitter and receiver. The receiver cannot receive light or the intensity of the received light is weakened, triggering the internal circuit of the photoelectric sensor, generating an electrical signal, and transmitting this signal to the control terminal. After receiving the signal, the control terminal activates the electric push rod, causing the pressure plate 5 to begin moving to adjust the position of the medicine bottle.

[0044] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
