[0022] Reference Figures 1 to 4 A negative pressure detection device for the sealing line of pharmaceutical packaging, comprising,

[0023] The detection chamber 1 and the control base 2 are provided. The inside of the detection chamber 1 is provided with a support platform 3 for supporting the medicine. The support platform 3 is used to support the drive component 4 and the clamping component 5, so as to ensure that the clamping component 5 can be adjusted in position in the detection chamber 1 with the support platform 3.

[0024] Furthermore, the drive assembly 4, which is set on the top of the support platform 3, includes a first motor 41 fixedly installed on the top wall of the drive assembly 4, and a first lead screw 44 is fixedly connected to the output end of the first motor 41; wherein, the first motor 41 provides power input to the drive assembly 4, and the rotation of the first lead screw 44 is achieved by driving the first motor 41, and the first motor 41 needs to have good waterproof performance.

[0025] The clamping assembly 5 includes a first limiting plate 51 rotatably connected to the top wall of the support platform 3 and a second limiting plate 52 fixedly connected to the outside of the first limiting plate 51. Multiple limiting plates 55 are provided on the adjacent sides of the first limiting plate 51 and the second limiting plate 52. The first limiting plate 51 and the second limiting plate 52 are fixedly connected, and the gap between them allows the limiting plates 55 to move.

[0026] Furthermore, the lifting assembly 6 includes a second motor 61 fixedly installed on the bottom wall inside the detection chamber 1. The second motor 61 provides power input to the lifting assembly 6, and like the first motor 41, it is waterproof.

[0027] Specifically, the drive assembly 4 also includes a movable block 43 threadedly connected to the outer wall of the first lead screw 44. A connecting plate 42 is fixedly connected to the outer wall of the movable block 43, and the connecting plate 42 is fixedly connected to the outer wall of the first limiting disk 51. The threaded connection between the first lead screw 44 and the movable block 43 enables the synchronous movement of the movable block 43, which in turn drives the first limiting disk 51 to rotate via the connecting plate 42.

[0028] Reference Figure 3 and Figure 4 A positioning rod 56 is fixedly connected to the outer wall of the limiting plate 55. The two ends of the positioning rod 56 are rotatably connected to the outer walls of the first limiting plate 51 and the second limiting plate 52, respectively. A movable plate 54 is slidably connected to the inner wall of the limiting plate 55. Since the limiting plate 55 is connected to the first limiting plate 51 and the second limiting plate 52 via the positioning rod 56, the limiting plate 55 moves in a corresponding trajectory during the rotation of the limiting plates, causing the movable plate 54 to move synchronously.

[0029] Specifically, a connecting rod 53 is rotatably connected to one end of the movable plate 54, and the connecting rod 53 is fixedly connected to the top wall of the support platform 3. A clamping plate 57 is rotatably connected to the other end of the movable plate 54. One end of the movable plate 54 is defined, and the other end is connected to the clamping plate 57. By moving multiple clamping plates 57 closer together or further apart, medicines of different sizes can be clamped to meet the needs of different situations.

[0030] Reference Figure 2 and Figure 4 The output end of the second motor 61 is fixedly connected to the second lead screw 62. The support platform 3 is threadedly connected to the outer wall of the second lead screw 62. The inner bottom wall of the detection chamber 1 is also fixedly connected to the guide rod 7, which passes through the outer wall of the support platform 3. The rotation of the second lead screw 62 drives the support platform 3 to move along the second lead screw 62, ensuring that the drug remains underwater throughout the detection process.

[0031] Specifically, the outer wall of the clamping disk 57 has a groove 8. The groove 8 on the outer wall of the clamping disk 57 can be used to lock and limit the empty capsule plate, and can also be used to clamp bottled medicines.

[0032] Working principle: When it is necessary to test the medicine packaging, the medicine to be tested is placed on the support platform 3 in the testing chamber 1. The first motor 41 is started, and the first motor 41 drives the first lead screw 44 to rotate. Through the threaded connection between the first lead screw 44 and the moving block 43, the moving block 43 can move along the direction of the first lead screw 44. Since the moving block 43 is fixedly connected to the first limiting plate 51 through the connecting plate 42, the first limiting plate 51 and the second limiting plate 52 can be rotated by the movement of the moving block 43.

[0033] During the rotation of the first limiting plate 51 and the second limiting plate 52, the outer surface of the limiting plate 55 is limited by the positioning rod 56, so that the limiting plate 55 moves synchronously with the second limiting plate 52. One end of the moving plate 54 is rotatably connected to the support platform 3 through the connecting rod 53, and the other end is suspended. Thus, the movement of the limiting plate 55 will drive the moving plate 54 to make a corresponding movement trajectory. Therefore, the multiple clamping plates 57 will move away from each other or move closer to each other. Since the items floating on the water surface are mostly lightweight items, such as empty capsules and plastic ampoules, they can be inserted into the grooves 8 on the outer wall of the clamping plate 57 to clamp the medicine. At the same time, for slightly heavier medicines, they can be placed in the inner grooves of the multiple clamping plates 57, so that the surface of the clamping plate 57 contacts the surface of the medicine to achieve the clamping effect. This allows the device to meet the clamping needs in different situations.

[0034] After the medicine is properly clamped, the second motor 61 is started, which drives the second lead screw 62 to rotate, causing the support platform 3 to rise or fall along the vertical direction of the second lead screw 62. The guide rod 7 ensures the certainty of the movement direction of the support platform 3. The movement of the support platform 3 can drive the drive assembly 4 and the clamping assembly 5 to rise and fall synchronously, ensuring that the medicine is underwater. Finally, the air is extracted by controlling the base 2 to maintain a negative pressure state in the detection chamber 1, thus realizing the detection operation.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
