Description

Technical Field

[0001] This utility model relates to the field of medical rubber stopper packaging technology, and in particular to a sterile packaging device for medical rubber stoppers. Background Technology

[0002] In the production process of medical rubber stoppers, after production, the stoppers need to be packaged in sterile plastic bags and then sealed. An existing patent (publication number: CN221341344U) discloses an automatic bagging device for medical rubber stoppers. This invention uses a bag-opening component and a suction unit to attract the sides of the packaging bag, thereby opening it without contacting the inside of the bag, preventing contamination and maintaining the rubber stoppers in a sterile environment. However, in practical applications, this invention only opens the bag; the subsequent sealing operation still requires the next stage of the process, reducing production efficiency. Therefore, we propose a sterile packaging device for medical rubber stoppers. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a sterile packaging device for medical rubber stoppers.

[0004] To achieve the above objectives, this utility model provides the following technical solution: Design a sterile packaging device for medical rubber stoppers, including a turntable mounted on a base. The turntable is connected to the base via a drive shaft. Positioning holes are evenly distributed along the edge of the turntable. A frame fixed to the base is mounted on one side of the turntable. An automatic sealing device is mounted on the frame and performs reciprocating linear motion between the frame and the turntable. An inflation mechanism is also provided above the turntable. The inflation mechanism includes an inflation tube located above the positioning holes and moving up and down.

[0005] In the above scheme, the bottom of the turntable is fixed with positioning cylinders that correspond one by one with the positioning holes, and the positioning cylinders are provided with observation holes.

[0006] In the above solution, the automatic sealing device includes a base, one end of which is connected to a pressure plate via a rotating shaft, and the rotating shaft is connected to a servo motor mounted on the base.

[0007] In the above scheme, pulleys are installed on both the output shaft and the rotating shaft of the servo motor, and a belt is connected between the pulleys.

[0008] In the above scheme, a support frame is fixed at the bottom of the base, a cylinder is installed on the frame and its stroke end is connected to the support frame, and a push port located on the side of the positioning hole is opened on the turntable.

[0009] In the above scheme, the inflation mechanism also includes a second frame fixed on the base, and an air supply pipe is installed on the second frame through a pipe clamp. A telescopic pipe is connected between the end of the inflation pipe and the air supply pipe.

[0010] In the above scheme, a ring is installed on the inflation pipe, a cylinder is installed on the top of the second frame, a lifting plate is connected downward at the stroke end of the cylinder, the lifting plate is fixed to the ring, and a distance sensor is installed on the top of the lifting plate.

[0011] The advantages and beneficial effects of this utility model are as follows: By setting up a frame, an automatic sealing device, and a cylinder, after the rubber stopper is filled into the plastic bag, the piston rod of the cylinder is extended to gradually push the machine base towards the turntable. During this process, a servo motor drives the rotating shaft, causing the pressure plate to rotate relative to the machine base, thereby adjusting the angle between the two and positioning the plastic bag between the machine base and the pressure plate. Then, by controlling the rotation of the rotating shaft, the machine base and the pressure plate are closed, thus sealing the plastic bag. Compared with the prior art, this automatic sealing method... The combination of the device's operational logic and the turntable's rotation enables the plastic bags, after being filled with rubber stoppers, to be automatically sealed during the circulation process. This not only improves the level of automation but also increases work efficiency. By setting up an inflation mechanism, before the rubber stopper is inserted into the plastic bag, the piston rod of the cylinder is extended, causing the lifting plate to lower the inflation tube until the end of the inflation tube extends into the opening of the plastic bag. Nitrogen gas is then injected into the plastic bag, causing it to expand and open to allow the rubber stopper to be inserted. This eliminates the need to touch the inside of the plastic bag, preventing contamination. Attached Figure Description

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a sterile packaging device for medical rubber stoppers, including a turntable 3 disposed on a base 1. The turntable 3 is connected to the base 1 via a drive shaft 2. A reduction motor connected to the drive shaft 2 is installed inside the base 1. The drive shaft 2 and the turntable 3 are coaxially fixed. Positioning holes 4 are evenly provided on the edge of the turntable 3. The number of positioning holes 4 is designed according to actual conditions; in this application, there are 6. Figure 1 As shown, the positioning hole 4 directly below the air tube 18 is designated as station 2, and the positioning hole 4 to its left is designated as station 1. Then, the positioning holes 4 are named in clockwise order as stations 3-5. Furthermore, the bottom of the turntable 3 is fixed with positioning cylinders 5 that correspond one-to-one with the positioning holes 4, and the positioning cylinders 5 are provided with observation holes 6. The plastic bag is inserted into the positioning hole 4 by means of an external robotic arm or manual means, and the positioning cylinders 5 are used to limit the plastic bag. The state of the plastic bag can be observed through the observation holes 6.

[0017] A frame 8 fixed to the base 1 is provided on one side of the turntable 3. An automatic sealing device 9 is provided on the frame 8. The automatic sealing device 9 makes reciprocating linear motion between the frame 8 and the turntable 3. Furthermore, the automatic sealing device 9 includes a base 91, one end of which is connected to the pressure plate 92 via a rotating shaft 93, and the rotating shaft 93 is connected to a servo motor 10 mounted on the base 91. Specifically, a heating element is provided on the opposite side of the base 91 and the pressure plate 92. The surface of the electric heating structure is covered with a high-temperature cloth. A working indicator light is provided on the base 91. A silicone pressure strip is provided on the opposite side of the pressure plate 92 and the base 91. The automatic sealing device 9 is similar in structure to the existing sealing machine. The core function of the sealing machine relies on the precise melting control of the plastic film by the heating element. After the heating element (such as a nickel-chromium alloy heating block) is powered on, it quickly heats up to the preset temperature (usually 120-200℃). The heat is transferred to the high-temperature cloth through heat conduction, so that the plastic molecular chains at the sealing point of the plastic bag are softened by heat. After reaching the melting point, they form a molten state and are naturally sealed after cooling. Its control system dynamically adjusts the heating power through a PID algorithm.

[0018] Furthermore, pulleys 11 are installed on both the output shaft of the servo motor 10 and the rotating shaft 93, and a belt is connected between the pulleys 11. The servo motor 10 provides power, and the rotating shaft 93 is rotated by the transmission effect of the pulleys 11 and the belt, which in turn causes the pressure plate 92 to rotate.

[0019] Furthermore, a support frame 12 is fixed at the bottom of the base 91, and a cylinder 13 connected to the support frame 12 is installed on the frame 8. A push port 7 located on the side of the positioning hole 4 is provided on the turntable 3. The push port 7 facilitates the automatic sealing device 9 to be pushed onto the turntable 3. Specifically, by setting up a frame 8, an automatic sealing device 9, and a cylinder 13, after the rubber stopper is filled into the plastic bag, the piston rod of the cylinder 13 is extended to gradually push the base 91 toward the turntable 3. During this process, the servo motor 10 drives the rotating shaft 93 to rotate the pressure plate 92 relative to the base 91, thereby adjusting the angle between the two and placing the plastic bag between the base 91 and the pressure plate 92. Then, by controlling the rotation of the rotating shaft 93, the base 91 and the pressure plate 92 are closed, thus sealing the plastic bag. Compared with the existing technology, combining the action logic of the automatic sealing device 9 with the rotation of the turntable 3 allows the plastic bag, after the rubber stopper has been filled, to be automatically sealed during the circulation process, which not only improves the degree of automation but also improves work efficiency.

[0020] An inflation mechanism is also provided above the turntable 3. The inflation mechanism includes an inflation tube 18 located above the positioning hole 4 and moving up and down. The inflation tube 18 is a rigid tube. Furthermore, the inflation mechanism also includes a frame 14 fixed on the base 1. A gas supply pipe 15 is installed on the frame 14 via a pipe clamp 16. The other end of the gas supply pipe 15 is connected to a nitrogen generator for supplying nitrogen. A telescopic pipe 17 is connected between the end of the inflation pipe 18 and the gas supply pipe 15. The telescopic pipe 17 is designed as a corrugated pipe. Both ends of the telescopic pipe 17 are connected to the inflation pipe 18 and the gas supply pipe 15 respectively via connectors. Furthermore, a ring 19 is installed on the inflation tube 18, and a cylinder 21 is installed on the top of the frame 2 14. The stroke end of the cylinder 21 is connected downward to a lifting plate 20. The lifting plate 20 is fixed to the ring 19, and a distance sensor 22 is installed on the top of the lifting plate 20. The distance sensor 22 is used to accurately measure the distance between the lifting plate 20 and the frame 2 14, and indirectly obtain the distance between the inflation tube 18 and the turntable 3, so as to accurately position the lowering height of the inflation tube 18. Specifically, by setting up an inflation mechanism, before the rubber stopper is put into the plastic bag, the piston rod of the second cylinder 21 is extended by controlling the lifting plate 20 to drive the inflation tube 18 down until the end of the inflation tube 18 extends into the opening of the plastic bag. By filling the plastic bag with nitrogen, the plastic bag expands and opens so that the rubber stopper can be put in. There is no need to touch the inside of the plastic bag, thus preventing the plastic bag from being contaminated.

[0021] Working principle: This utility model is designed for use in sterile workshops; First, an empty plastic bag is placed at station one. When station one moves to station two, the plastic bag is inflated using the inflation tube 18. At this time, a rubber stopper is inserted into the plastic bag. Then, when it continues to move to the next station, the plastic bag is sealed using the automatic sealing device 9. Then it moves to station four and is finally taken away at station four. Station six can be used as a picking station for different models of products. For example, a plastic bag with a rubber stopper of model a is taken away at station four, and a plastic bag with a rubber stopper of model b is taken away at station six.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
