Description

Technical Field

[0001] This invention relates to the field of thermal testing equipment technology, specifically to a thermal testing station for pharmaceutical glass bottles. Background Technology

[0002] Pharmaceutical glass bottles are characterized by their smooth transparency, ease of sterilization, corrosion resistance, high-temperature resistance, and excellent sealing performance. They remain the preferred packaging for common infusions, antibiotics, powders, lyophilized products, vaccines, blood, and biological agents. Before leaving the factory, pharmaceutical glass bottles undergo a quality test using a heating method to ensure their quality.

[0003] Chinese invention patent CN210487665U discloses a rotating thermal testing station for glass bottles, which can perform thermal testing on multiple glass bottles, greatly improving work efficiency. However, during use, the clamps tightly hold the bottom of the glass bottles, preventing the bottom from receiving sufficient heating and resulting in uneven heating of the entire glass bottle, leading to unsatisfactory thermal testing results. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the purpose of this invention is to provide a heat testing station for pharmaceutical glass bottles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat testing station for pharmaceutical glass bottles, comprising a workbench, on which a heat testing box is fixedly mounted, and a heat testing channel running transversely through the heat testing box and the workbench, comprising:

[0006] The guide rail passes laterally through the thermal inspection channel and is fixedly connected to the worktable. The slider is mounted on the guide rail and is slidably connected to it. Multiple downward-extending limiting holes, spaced apart along the length of the guide rail, are provided on both sides of the top of the slider. These limiting holes are adapted to pharmaceutical glass bottles. Inwardly extending grooves are provided on both sides of the slider. These extending grooves communicate with the limiting holes on the same side via guide holes. Multiple downward-extending limiting grooves are provided at the bottom of the extending grooves, and each limiting groove corresponds to one of the limiting holes on the same side.

[0007] Multiple lifting components are provided, each corresponding to one of the multiple limiting holes. Each lifting component includes a limiting block, a lifting plate, a guide rod, and a drive rod. The limiting block is disposed in the corresponding limiting groove and is slidably connected to the inner wall of the limiting groove. The lifting plate is disposed laterally in the corresponding limiting hole. The guide rod is disposed longitudinally in the guide hole and is slidably connected to the inner wall of the guide hole. The upper and lower ends of the guide rod are respectively connected to the lifting plate and the limiting block. The drive rod is disposed laterally and is connected to the limiting block.

[0008] Two drive plates, both of which pass laterally through the thermal testing channel and are fixedly connected to the worktable, are located on opposite sides of the thermal testing channel. The first end of each drive plate has an upwardly inclined and inwardly extending guide surface that contacts the drive rod. The top of each drive plate is horizontal.

[0009] A driving mechanism is provided for driving the slider to slide on the guide rail.

[0010] Furthermore, the upper end of the guide rod is fixedly connected to the lifting plate, the lower end of the guide rod is rotatably connected to the limiting block, and a gear is fixedly installed on the guide rod;

[0011] The inner walls on both sides of the thermal testing channel are fixedly equipped with racks arranged in a transverse direction, and the racks mesh with gears on the same side.

[0012] Furthermore, the drive rod is rotatably connected to the limiting block.

[0013] Furthermore, the driving mechanism includes a lead screw and a motor. The lead screw passes laterally through the slider and is rotatably connected to the worktable at both ends. The lead screw is threadedly connected to the slider. The motor is fixedly mounted on the worktable and is used to control the rotation of the lead screw.

[0014] Furthermore, it also includes a sealing mechanism, which includes a sealing plate, a connecting plate, and an electric push rod. The sealing plate has two pieces, which are respectively arranged longitudinally at both ends of the thermal inspection channel. Both ends of the connecting plate are fixedly connected to the two sealing plates. The electric push rod is arranged longitudinally, and the cylinder of the electric push rod is fixedly connected to the worktable. The piston rod of the electric push rod is fixedly connected to the connecting plate.

[0015] Furthermore, it also includes a fixed platform, a receiving platform, and a pushing mechanism. The fixed platform and the receiving platform are both located at the tail end of the thermal inspection channel and on both sides of the thermal inspection channel, respectively. The fixed platform and the receiving platform are both fixedly connected to the workbench. The pushing mechanism is used to push the pharmaceutical glass bottles onto the receiving platform. The pushing mechanism includes a cylinder and a push plate. The cylinder is arranged laterally, and the cylinder body is fixedly connected to the fixed platform. The push plate is fixedly installed on the piston rod of the cylinder.

[0016] Furthermore, a U-shaped plate is fixedly installed on the top of the receiving platform, and baffles are fixedly installed on both sides of the push plate.

[0017] The beneficial effects of this invention are as follows: The pharmaceutical glass bottle thermal testing station provided by this invention, when the drive mechanism is activated, the drive rod gradually contacts the guide surface and horizontal surface on the drive plate. During this contact process, the lifting plate gradually lifts the pharmaceutical glass bottle upwards. When the pharmaceutical glass bottle enters the thermal testing channel, the bottom of the bottle disengages from the limiting hole. Thus, when the heater in the thermal testing channel is activated, the bottom of the pharmaceutical glass bottle receives sufficient heating, resulting in uniform heating of the entire bottle and a more ideal thermal testing effect.

[0032] like Figure 1-9As shown, this invention provides a thermal testing station for pharmaceutical glass bottles, including a workbench 10. A thermal testing box 11 is fixedly installed on the workbench 10, forming a transverse thermal testing channel 12 between the thermal testing box 11 and the workbench 10. A heater and a thermal testing element are fixedly installed on the inner wall of the thermal testing channel 12, and both the heater and the thermal testing element are electrically connected to an external control cabinet. The above descriptions are all prior art, and the specific structure will not be elaborated further. This invention also includes a guide rail 20, a slider 21, a lifting assembly 30, a drive plate 40, and a drive mechanism 50.

[0033] The guide rail 20 passes laterally through the heat inspection channel 12 and is fixedly connected to the workbench 10. The slider 21 is mounted on the guide rail 20 and slidably connected to it. Multiple downward-extending limiting holes 22, evenly spaced along the length of the guide rail 20, are provided on both sides of the top of the slider 21. These limiting holes 22 are adapted to the pharmaceutical glass bottle. Inwardly extending grooves 23 are provided on both sides of the slider 21, and these grooves 23 communicate with the limiting holes 22 on the same side via guide holes 24. Multiple downward-extending limiting grooves 26 are provided at the bottom of the extending grooves 23, each corresponding to one of the limiting holes 22 on the same side.

[0034] Multiple lifting assemblies 30 are provided, each corresponding to a specific limiting hole 22. Each lifting assembly 30 includes a limiting block 31, a lifting plate 32, a guide rod 33, and a drive rod 34. The limiting block 31 is disposed within a corresponding limiting groove 26 and slidably connected to the inner wall of the limiting groove 26. The lifting plate 32 is disposed laterally within a corresponding limiting hole 22 and conforms to the limiting hole 22. The guide rod 33 is disposed longitudinally within a guide hole 24 and slidably connected to the inner wall of the guide hole 24; its upper and lower ends are connected to the lifting plate 32 and the limiting block 31, respectively. The drive rod 34 is disposed laterally and connected to the limiting block 31.

[0035] Two drive plates 40 are provided, each passing laterally through the thermal inspection channel 12 and fixedly connected to the worktable 10. The two drive plates 40 are located on opposite sides of the thermal inspection channel 12. Each drive plate 40 has an upwardly inclined and inwardly extending guide surface 41 at its first end. When the guide surface 41 contacts the drive rod 34, it causes the drive rod 34 to tend to move upward. The top of the drive plate 40 is a horizontal surface 42.

[0036] The drive mechanism 50 is used to drive the slider 21 to slide on the guide rail 20.

[0037] In the initial state, the slider 21 is located in front of the thermal inspection channel 12. The operator places a medicine glass bottle into each limiting hole 22, and the medicine glass bottle is confined within the corresponding limiting hole 22.

[0038] The specific operating process is as follows: The operator starts the drive mechanism 50, which moves the slider 21 towards the thermal testing channel 12. During this movement, the drive rod 34 gradually contacts the guide surface 41 on the drive plate 40. Since the guide surface 41 is inclined upwards, the drive rod 34 drives the guide rod 33 and the lifting plate 32 to move upwards simultaneously. The lifting plate 32 then gradually lifts the medicine glass bottle upwards. When all the drive rods 34 are in contact with the horizontal surface 42, all the medicine glass bottles stop moving upwards. At this point, all the medicine glass bottles have just entered the thermal testing channel 12, and the bottoms of all the medicine glass bottles are disengaged from the limiting holes 22, with the bottoms of all the medicine glass bottles flush with the top of the slider 21. Then, the external control cabinet starts the heater inside the thermal testing channel 12, ensuring sufficient heating of the bottoms of the medicine glass bottles. This results in uniform heating of the entire medicine glass bottle and a more ideal thermal detection effect from the thermal testing element.

[0039] After the thermal test is completed, the drive mechanism 50 continues to start until the slider 21 moves to the end of the thermal test channel 12, removes all the pharmaceutical glass bottles, and then resets all the parts to their initial state to prepare for the next operation.

[0040] In one embodiment, the upper end of the guide rod 33 is fixedly connected to the lifting plate 32, the lower end of the guide rod 33 is rotatably connected to the limiting block 31, and a gear 35 is fixedly installed on the guide rod 33.

[0041] The inner walls on both sides of the thermal inspection channel 12 are fixedly installed with racks 13 arranged in the transverse direction, and the racks 13 mesh with the gears 35 on the same side.

[0042] During the movement of slider 21 controlled by drive mechanism 50, when gear 35 meshes with rack 13, the bottom of all pharmaceutical glass bottles is flush with the top of slider 21. As slider 21 continues to move, gear 35 drives guide rod 33 and lifting plate 32 to rotate, which in turn causes the pharmaceutical glass bottles to rotate. Drive mechanism 50 controls slider 21 to move back and forth in the heat testing channel 12, keeping the pharmaceutical glass bottles in a rotating state, resulting in more uniform heating of the entire pharmaceutical glass bottle.

[0043] In one embodiment, the drive rod 34 is rotatably connected to the limiting block 31. Thus, when the drive rod 34 contacts the guide surface 41 and the horizontal surface 42, the drive rod 34 will rotate and roll on the guide surface 41 and the horizontal surface 42, reducing wear.

[0044] In one embodiment, the drive mechanism 50 includes a lead screw 51 and a motor 52. The lead screw 51 passes laterally through the slider 21 and is rotatably connected to the worktable 10 at both ends. The lead screw 51 is threadedly connected to the slider 21 and remains parallel to the guide rail 20. The motor 52 is fixedly mounted on the worktable 10 and is used to control the rotation of the lead screw 51. The motor 52 is electrically connected to an external control cabinet.

[0045] When the drive mechanism 50 is started, the motor 52 drives the lead screw 51 to rotate in both directions. Under the constraint of the guide rail 20, the slider 21 moves back and forth on the guide rail 20. This drive mechanism 50 has a simple structure and is convenient for production and manufacturing.

[0046] In one embodiment, a sealing mechanism 60 is further included, comprising a sealing plate 61, a connecting plate 62, and an electric push rod 63. Two sealing plates 61 are respectively arranged longitudinally at both ends of the thermal testing channel 12. Both ends of the connecting plate 62 are fixedly connected to both sealing plates 61. The electric push rod 63 is arranged longitudinally, its cylinder is fixedly connected to the worktable 10, its piston rod is fixedly connected to the connecting plate 62, and it is electrically connected to an external control cabinet.

[0047] In the initial state, the electric push rod 63 is in the extended state, at which time the closed plate 61 is higher than the worktable 10, and the slider 21 can smoothly enter the thermal inspection channel 12.

[0048] Once slider 21 is fully inserted into thermal testing channel 12, the external control cabinet controls the electric push rod 63 to retract, at which point the two sealing plates 61 completely seal both ends of thermal testing channel 12. This minimizes heat loss when the heater and thermal testing element are activated.

[0049] In one embodiment, the system further includes a fixed platform 14, a receiving platform 15, and a pushing mechanism 70. The fixed platform 14 and the receiving platform 15 are both located at the tail end of the heat testing channel 12 and on opposite sides of the channel, respectively. Both are fixedly connected to the workbench 10. The pushing mechanism 70 is used to push the pharmaceutical glass bottles onto the receiving platform 15. The pushing mechanism 70 includes a cylinder 71 and a pusher plate 72. The cylinder 71 is arranged laterally, and its body is fixedly connected to the fixed platform 14. The pusher plate 72 is fixedly mounted on the piston rod of the cylinder 71.

[0050] Initially, cylinder 71 is in the retracted state.

[0051] When slider 21 moves to the end of heat inspection channel 12, the piston rod of cylinder 71 controlled by the external control cabinet extends. At this time, pusher plate 72 pushes all the pharmaceutical glass bottles onto receiving platform 15 for easy collection and sorting by staff. Then, the piston rod of cylinder 71 returns to its original position.

[0052] In one embodiment, a U-shaped plate 16 is fixedly installed on the top of the receiving platform 15. The design of the U-shaped plate 16 can block the pharmaceutical glass bottles on the receiving platform 15 and prevent them from falling. Baffles 73 are fixedly installed on both sides of the push plate 72. The design of the baffles 73 can prevent the pharmaceutical glass bottles from sliding to the sides when pushing them, thereby ensuring that the pharmaceutical glass bottles enter the receiving platform 15.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or basic characteristics. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.

[0054] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
