Description

Technical Field

[0001] This utility model relates to the technical field of butyl rubber stopper sealing performance testing device, specifically a butyl rubber stopper sealing performance testing device with a sorting structure. Background Technology

[0002] In the pharmaceutical field, butyl rubber stoppers, with their high cleanliness, heat resistance, and acid and alkali resistance, have become the preferred sealing material for packaging such as injection vials and lyophilized preparations. They can effectively block the penetration of oxygen and water vapor, extending the shelf life of medicines. After siliconization treatment, their surface can reduce rubber debris shedding and lower the coefficient of friction with glass bottles, improving the efficiency of automated production.

[0003] Butyl rubber stoppers may fail to meet sealing standards due to cracks or insufficient rubber. Traditional butyl rubber stopper sealing testing devices are not convenient for distinguishing between qualified and unqualified butyl rubber stoppers after testing. This may result in a mixture of qualified and unqualified butyl rubber stoppers, which is not conducive to subsequent work. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a butyl rubber stopper sealing performance testing device with a sorting structure. This device has the advantage of classifying butyl rubber stoppers as qualified or unqualified after testing, thus solving the problem that traditional butyl rubber stopper sealing performance testing devices are not convenient for classifying butyl rubber stoppers by quality after testing, and are prone to confusing some unqualified products with qualified products.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a butyl rubber stopper sealing performance testing device with a sorting structure, comprising a base plate and a top plate, the top plate being disposed above the base plate, a support column being fixedly connected between the top plate and the base plate, a miniature vacuum pump and a glass tube being fixedly installed on the top of the top plate, the miniature vacuum pump and the glass tube being fixedly connected via an air pipe, a pressure detector being fixedly installed on the glass tube, a moving mechanism being provided on the top of the top plate, a sorting mechanism being provided on the top of the base plate, and butyl rubber stoppers being disposed on the moving mechanism. The moving mechanism is used to move the butyl rubber stopper to perform a sealing test on the butyl rubber stopper. The sorting mechanism is used to sort butyl rubber stoppers into qualified and unqualified categories after the inspection is completed.

[0006] In a preferred embodiment of this utility model, the moving mechanism includes an electric telescopic rod, a connecting plate, and a locking block. The electric telescopic rod is fixedly connected to the top of the top plate. The telescopic end of the electric telescopic rod on the left side is fixedly connected to the connecting plate. The front side of the connecting plate is fixedly connected to the locking block. The butyl rubber stopper is engaged inside the locking block. The locking block is directly opposite the left end of the glass tube.

[0007] In a preferred embodiment of this utility model, the sorting mechanism includes a motor, a drive gear, a driven gear, a rotating rod, and a sorting shell. The motor is fixedly installed on the top of the base plate, and the output end on the left side of the motor is fixedly connected to the drive gear. The driven gear meshes with the drive gear and is fixedly sleeved on the surface of the rotating rod. The sorting shell is fixedly installed on the left end of the rotating rod.

[0008] In a preferred embodiment of this invention, a support block is rotatably connected to the surface of the rotating rod via a bearing, and the bottom of the support block is fixedly connected to the base plate. In another preferred embodiment, a connecting rod is fixedly connected to the left side of the top plate, and a pin is fixedly connected to the right side of the connecting rod. A through hole is formed on the left side of the locking block, and the diameter of the pin is smaller than the diameter of the through hole, with the pin positioned directly opposite the left side of the through hole.

[0009] As a preferred embodiment of this utility model, a baffle is fixedly connected to the top of the sorting shell, the baffle is inclined, and two collection boxes are fixedly connected to the left side of the bottom plate, the two collection boxes being distributed front to back.

[0010] As a preferred embodiment of this utility model, the top of the top plate is fixedly connected to controller one and controller two. Controller one is used in conjunction with the electric telescopic rod, and controller two is used in conjunction with the motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a moving mechanism to engage the butyl rubber stopper inside the locking block. Then, the controller retracts the electric telescopic rod, which moves the connecting plate and the locking block synchronously closer to the glass tube. The butyl rubber stopper, driven by the locking block, will fit tightly against the glass tube. At this point, a micro vacuum pump is activated to remove air from the glass tube, creating a vacuum. If the butyl rubber stopper is qualified, the pressure gauge will not change after a period of time. If it is unqualified, the internal pressure of the glass tube will gradually recover after a period of time, causing a change in the pressure gauge reading. After the test is completed, the operator controls the electric telescopic rod to move the butyl rubber stopper... As the butyl rubber stopper leaves the glass tube, the motor drives the drive gear to rotate. The drive gear, through the driven gear, drives the rotating rod to rotate, which in turn drives the sorting shell to rotate. If a qualified butyl rubber stopper falls into the sorting shell, the motor can be controlled to rotate the sorting shell forward, and the qualified butyl rubber stopper will fall into the front collection box. Conversely, unqualified ones fall into the rear collection box. This solves the problem that traditional butyl rubber stopper sealing detection devices are not convenient for classifying butyl rubber stoppers by quality after testing, which can easily lead to confusion between some unqualified products and qualified products. This achieves the effect of classifying butyl rubber stoppers as qualified or unqualified after testing, preventing subsequent confusion.

[0012] 2. This utility model uses a moving mechanism to engage the butyl rubber stopper inside the locking block. Then, the controller retracts the electric telescopic rod, which moves the connecting plate and the locking block synchronously closer to the glass tube. Under the action of the locking block, the butyl rubber stopper fits tightly against the glass tube. At this point, a micro vacuum pump is activated to remove the air from the glass tube, creating a vacuum state for testing. The air pressure is then used to determine whether the test is qualified. After the test is completed, the operator controls the electric telescopic rod to move the butyl rubber stopper away from the glass tube. This method is convenient and improves testing efficiency.

[0013] 3. This utility model, by setting up a sorting mechanism, uses a motor to drive the drive gear to rotate, which in turn drives the rotating rod to rotate via the driven gear. The rotating rod then drives the sorting shell to rotate. If a qualified butyl rubber stopper falls into the sorting shell, the motor can be controlled to rotate the sorting shell forward, and the qualified butyl rubber stopper will fall into the front collection box. Conversely, unqualified ones fall into the rear collection box, thus separating qualified and unqualified butyl rubber stoppers in a timely manner to prevent confusion and facilitate subsequent work.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0020] Example 1 Reference Figure 1-4 This is the first embodiment of the present invention, which provides a base plate 1 and a top plate 2. The top plate 2 is disposed above the base plate 1. A support column 3 is fixedly connected between the top plate 2 and the base plate 1. A miniature vacuum pump 4 and a glass tube 5 are fixedly installed on the top of the top plate 2. The miniature vacuum pump 4 and the glass tube 5 are fixedly connected by an air pipe. A pressure detector 6 is fixedly installed on the glass tube 5. A moving mechanism is also provided on the top of the top plate 2, and a sorting mechanism is provided on the top of the base plate 1. A butyl rubber stopper 7 is provided on the moving mechanism. The moving mechanism is used to move the butyl rubber stopper 7 to perform a sealing test on the butyl rubber stopper 7. The sorting mechanism is used to sort butyl rubber stoppers 7 into qualified and unqualified categories after testing.

[0021] Specifically, this achieves the effect of classifying butyl rubber stoppers as qualified or unqualified after testing, thus preventing confusion in the future.

[0022] Furthermore, the butyl rubber stopper 7 is secured inside the locking block 10. Then, the electric telescopic rod 8 is retracted via the controller 22. The electric telescopic rod 8 drives the connecting plate 9 and the locking block 10 to move synchronously and approach the glass tube 5. Under the action of the locking block 10, the butyl rubber stopper 7 will fit tightly against the glass tube 5. At this time, the micro vacuum pump 4 is activated to evacuate the air from the glass tube 5, creating a vacuum inside. If the butyl rubber stopper 7 is qualified, the pressure detector 6 will not change after a period of time. If it is unqualified, the air pressure inside the glass tube 5 will change after a period of time. As the air pressure gradually recovers, the air pressure detector 6 changes. After the test is completed, the staff controls the electric telescopic rod 8 to move the butyl rubber stopper 7 away from the glass tube 5. The motor 11 drives the drive gear 12 to rotate. The drive gear 12 drives the rotating rod 14 to rotate through the driven gear 13. The rotating rod 14 drives the sorting shell 15 to rotate. If the qualified butyl rubber stopper 7 falls into the sorting shell 15, the motor 11 can be controlled to make the sorting shell 15 rotate forward. The qualified butyl rubber stopper 7 will fall into the front collection box 21. Otherwise, the unqualified ones will fall into the rear collection box 21.

[0023] The top of the top plate 2 is fixedly connected to controller 1 22 and controller 2 23. Controller 1 22 is used in conjunction with the electric telescopic rod 8, and controller 2 23 is used in conjunction with the motor 11. The controllers improve the convenience of operation and further enhance the detection efficiency.

[0024] Example 2 The second embodiment of this utility model provides a moving mechanism including an electric telescopic rod 8, a connecting plate 9, and a locking block 10. The electric telescopic rod 8 is fixedly connected to the top of the top plate 2. The telescopic end on the left side of the electric telescopic rod 8 is fixedly connected to the connecting plate 9. The front side of the connecting plate 9 is fixedly connected to the locking block 10. The butyl rubber stopper 7 is engaged inside the locking block 10. The locking block 10 is directly opposite the left end of the glass tube 5.

[0025] Specifically, the moving mechanism makes the butyl rubber stopper 7 fit more tightly and stably with the glass tube 5, which is conducive to the development of the testing work and is easy to operate, thus improving the testing efficiency.

[0026] Furthermore, the butyl rubber stopper 7 is engaged inside the locking block 10. Then, the electric telescopic rod 8 is retracted by the controller 22. The electric telescopic rod 8 drives the connecting plate 9 and the locking block 10 to move synchronously and approach the glass tube 5. Under the action of the locking block 10, the butyl rubber stopper 7 will fit tightly against the glass tube 5. At this time, the micro vacuum pump 4 is started to remove the air from the glass tube 5 and make its interior a vacuum state. If the butyl rubber stopper 7 is qualified, the air pressure detector 6 will not change after a period of time. If it is unqualified, the air pressure inside the glass tube 5 will gradually recover after a period of time. At this time, the air pressure detector 6 will change. After the test is completed, the staff controls the electric telescopic rod 8 to move the butyl rubber stopper 7 away from the glass tube 5.

[0027] A connecting rod 17 is fixedly connected to the left side of the top plate 2, and a ejector pin 18 is fixedly connected to the right side of the connecting rod 17. A through hole 19 is opened on the left side of the locking block 10. The diameter of the ejector pin 18 is smaller than the diameter of the through hole 19, and the ejector pin 18 is directly opposite the left side of the through hole 19. After the inspection is completed, the electric telescopic rod 8 drives the locking block 10 to move to the left. During this process, the ejector pin 18 will insert into the through hole 19, pushing the butyl rubber stopper 7 out of the locking block 10 and causing the butyl rubber stopper 7 to fall into the sorting shell 15 below, which facilitates the quick replacement of the butyl rubber stopper 7 and improves the convenience of operation.

[0028] Example 3 The third embodiment of this utility model provides a sorting mechanism including a motor 11, a driving gear 12, a driven gear 13, a rotating rod 14, and a sorting shell 15. The motor 11 is fixedly installed on the top of the base plate 1. The output end of the motor 11 on the left side is fixedly connected to the driving gear 12. The driven gear 13 meshes with the driving gear 12 and is fixedly sleeved on the surface of the rotating rod 14. The sorting shell 15 is fixedly installed on the left end of the rotating rod 14.

[0029] Specifically, the sorting mechanism can promptly separate qualified and unqualified butyl rubber stoppers 7 to prevent confusion and facilitate subsequent work.

[0030] Furthermore, the staff can control the motor 11 to rotate via the controller 23. The motor 11 drives the drive gear 12 to rotate, and the drive gear 12 drives the rotating rod 14 to rotate via the driven gear 13. The rotating rod 14 drives the sorting shell 15 to rotate. If a qualified butyl rubber stopper 7 falls into the sorting shell 15, the motor 11 can be controlled to rotate the sorting shell 15 forward. The qualified butyl rubber stopper 7 will fall into the front collection box 21, and the unqualified ones will fall into the rear collection box 21.

[0031] A support block 16 is rotatably connected to the surface of the rotating rod 14 via a bearing, and the bottom of the support block 16 is fixedly connected to the base plate 1. The support block 16 provides support for the rotating rod 14, keeping the rotating rod 14 stable during rotation.

[0032] A baffle 20 is fixedly connected to the top of the sorting shell 15. The baffle 20 is inclined. Two collection boxes 21 are fixedly connected to the left side of the bottom plate 1. The two collection boxes 21 are distributed one in front of the other. When the butyl rubber stopper 7 falls, it will fall onto the baffle 20 and then slide into the sorting shell 15. The baffle 20 blocks the falling butyl rubber stopper 7, reduces its moving speed, and effectively prevents it from popping out of the sorting shell 15 due to excessive speed. The collection boxes 21 collect the sorted butyl rubber stoppers 7.

[0033] Working principle: The butyl rubber stopper 7 is engaged inside the locking block 10. Then, the electric telescopic rod 8 is retracted via the controller 22. The electric telescopic rod 8 moves the connecting plate 9 and the locking block 10 synchronously, approaching the glass tube 5. Under the action of the locking block 10, the butyl rubber stopper 7 will fit tightly against the glass tube 5. At this point, the micro vacuum pump 4 is activated to evacuate the air from the glass tube 5, creating a vacuum. If the butyl rubber stopper 7 is qualified, the pressure detector 6 will not change after a period of time. If it is unqualified, the internal pressure of the glass tube 5 will gradually recover after a period of time, at which point the pressure detector 6 will change. After the test is completed, the operator controls the electric telescopic rod 8 to move the butyl rubber stopper 7 away from the glass tube 5. The moving mechanism ensures that the butyl rubber stopper 7 fits more tightly and stably against the glass tube 5, facilitating the testing process and improving efficiency. The electric telescopic rod 8 moves the locking block 10 to the left, during which the ejector pin 18 inserts into the through hole 19, pushing the butyl rubber stopper 7 out of the locking block 10. The butyl rubber stopper 7 falls into the sorting shell 15 below, facilitating quick replacement and improving operational convenience. As the butyl rubber stopper 7 falls, it lands on the baffle 20 and then slides into the sorting shell 15. The baffle 20 blocks the falling butyl rubber stopper 7, reducing its speed and effectively preventing it from popping out of the sorting shell 15 due to excessive speed. The collection box 21 collects the sorted butyl rubber stoppers 7. The operator can control the motor 11 to rotate via the controller 23, and the motor 11 drives the drive gear 1. 2. Rotation: The drive gear 12 drives the rotating rod 14 to rotate via the driven gear 13. The rotating rod 14 drives the sorting shell 15 to rotate. If a qualified butyl rubber stopper 7 falls into the sorting shell 15, the motor 11 can be controlled to make the sorting shell 15 rotate forward. The qualified butyl rubber stopper 7 will fall into the front collection box 21. Conversely, the unqualified ones fall into the rear collection box 21. The sorting mechanism can promptly separate qualified and unqualified butyl rubber stoppers 7 to prevent confusion in the future and facilitate subsequent work.

[0034] In summary, the cooperation between the moving mechanism and the sorting mechanism enables the butyl rubber stoppers to be classified as qualified or unqualified after inspection, thus preventing confusion in the future.
