[0002] Suppositories are solid preparations made of drugs and matrix, which are mainly used in cavities such as the anus, vagina and urethra to lubricate, relieve itching and sterilize. Whether the suppository can achieve good therapeutic effects in the cavity is directly affected by the suppository matrix. Therefore, the suppository matrix is ​​required to have a certain hardness and be able to wrap the internal drug well before use to protect the drug from loss. After production, the suppositories need to be sampled to determine whether the batch of suppositories is qualified. Among them, the packaging test of the suppository matrix is ​​an important one, which requires the use of a vacuum leak detection device.

[0003] When the existing vacuum leak detection device is used to detect suppositories, the suppository to be detected is simply placed into the detection device.

[0024] A fast vacuum leak detection device for suppositories provided by an embodiment of the utility model is now described. A fast vacuum leak detection device for suppositories comprises a workbench 1, the upper end of the workbench 1 is fixedly connected with a pressure display instrument 6 and a first support platform 9, a vacuum cover 5 is placed on the upper end of the first support platform 9, the upper end of the first support platform 9 is fixedly connected with a second support platform 18 and a pressure detector 23, the pressure detector 23 is electrically connected to the pressure display instrument 6, the second support platform 18 is located at the center of the upper end of the first support platform 9, the upper end of the first support platform 9 is provided with a first squeezing mechanism and a second squeezing mechanism, the first squeezing mechanism is used to squeeze the left and right ends of the suppository, and the second squeezing mechanism is used to squeeze the front and rear ends of the suppository, the lower end of the workbench 1 is fixedly connected with a vacuum suction pump 7, the output end of the vacuum suction pump 7 is fixedly connected with a connecting pipe 8, and the connecting pipe 8 runs through the workbench 1 and the first support platform 9. During operation, the suppository to be tested for leaks is placed on the upper end of the second support platform 18, and then the vacuum cover 5 is covered, and the vacuum suction pump 7 is controlled to work so that the connecting pipe 8 sucks out the air between the vacuum cover 5 and the first support platform 9, thereby making the vacuum cover 5 in a vacuum state. At this time, the value displayed by the pressure display 6 is observed, and then the first extrusion mechanism and the second extrusion mechanism are controlled to extrude the suppository on the upper end of the second support platform 18. The pressure condition inside the vacuum cover 5 is detected by the pressure detector 23 and displayed by the pressure display 6. The pressure value at this time should be a stable value. If the pressure value in the vacuum cover 5 shown by the pressure display 6 changes, it means that the suppository is damaged and leaking. If the pressure value in the vacuum cover 5 shown by the pressure display 6 does not change, the first extrusion mechanism is reversely controlled to separate the first extrusion mechanism from the suppository, and the suppository is squeezed only by the second extrusion mechanism to observe whether the pressure value displayed by the pressure display 6 changes. If the suppository leaks, it will be immediately detected by the pressure detector 23, and the change in the pressure value will be displayed by the pressure display 6; when the pressure value displayed by the pressure display 6 does not change, the suppository is squeezed by the first squeezing mechanism, and the second squeezing mechanism is separated from the suppository. At this time, it is observed again whether the pressure value displayed by the pressure display 6 changes, so that the suppository can be quickly leaked.

[0025] The utility model provides a fast vacuum leak detection device for suppositories. Compared with the prior art, when leak detection is performed on suppositories, the suppository is slowly squeezed by the first squeezing mechanism or the second squeezing mechanism, so that the outer packaging of the suppository is gradually deformed. If the suppository leaks, the air can be quickly exhausted to the outside, so that the pressure detector 23 at the upper end of the first support platform 9 can more quickly detect whether the suppository is leaking, thereby improving work efficiency.

[0026] In another embodiment of the present invention, please refer to Figures 2 to 5 A sealing ring 11 is fixedly installed inside the first supporting platform 9 .

[0027] During operation, when the vacuum cover 5 is pressed against the upper end of the first support platform 9, the vacuum cover 5 will directly contact the sealing ring 11, thereby improving the sealing effect between the vacuum cover 5 and the first support platform 9, making the result of detecting the leakage of suppositories more accurate.

[0028] In another embodiment of the present invention, please refer to Figures 2 to 5 The upper end of the workbench 1 is fixedly connected to a fixed frame 2, the upper end of the fixed frame 2 is fixedly connected to a hydraulic telescopic rod 3, the output end of the hydraulic telescopic rod 3 is fixedly connected to a pressing plate 4, and the pressing plate 4 is located directly above the first supporting platform 9.

[0029] Before leak detection of the suppository, it is necessary to control the hydraulic telescopic rod 3 to work and drive the pressing plate 4 to move downward until the pressing plate 4 is tightly pressed on the upper end of the vacuum cover 5. At this time, the vacuum cover 5 can be firmly located on the upper end of the first support platform 9, and the suppository can be leak detected smoothly.

[0030] In another embodiment of the present invention, refer to Figures 1 to 5 The circumferential surface of the vacuum cover 5 is fixedly connected with a first ear plate 10, the circumferential surface of the first support platform 9 is fixedly connected with a second ear plate 12, the upper end of the second ear plate 12 is fixedly connected with a fixed shaft 13, the fixed shaft 13 passes through the first ear plate 10, and the first ear plate 10 is slidably connected to the fixed shaft 13.

[0031] During operation, the first ear plate 10, the second ear plate 12 and the fixed shaft 13 play a role in positioning the installation of the vacuum cover 5, so that the vacuum cover 5 can be placed on the upper end of the first support platform 9 more quickly and accurately.

[0032] In another embodiment of the present invention, please refer to Figures 2 to 5 The first extrusion mechanism includes a support seat 15, an electric telescopic rod 16 and a first extrusion block 17. The upper end of the first support platform 9 is fixedly connected to the support seat 15, the interior of the support seat 15 is fixedly connected to the electric telescopic rod 16, and the output end of the electric telescopic rod 16 is fixedly connected to the first extrusion block 17. There are two first extrusion blocks 17, two electric telescopic rods 16 and two support seats 15, and they are respectively located at the left and right ends of the second support platform 18.

[0033] When working, the two electric telescopic rods 16 at the left and right ends of the second support platform 18 are started to drive the two first squeezing blocks 17 to move toward each other. As the first squeezing blocks 17 move, the left and right ends of the suppository can be squeezed, so that the suppository is deformed, and the internal gas of the suppository is squeezed. If the suppository leaks, it can be detected more quickly.

[0034] In another embodiment of the present invention, please refer to Figures 2 to 5 The second extrusion mechanism includes a motor 14, a bidirectional threaded rod 21, a bearing seat 20, a second extrusion block 19 and a guide rod 22. The upper end of the first support platform 9 is fixedly connected with the bearing seat 20. Two bearing seats 20 are provided, and the two bearing seats 20 are respectively located at the front and rear ends of the second support platform 18. A guide rod 22 is fixedly connected between the two bearing seats 20. The two bearing seats 20 are connected by a bidirectional threaded rod 21. The bidirectional threaded rod 21 penetrates the bearing seat 20, and the bidirectional threaded rod 21 is rotatably connected to the bearing seat 20. The front end of the bearing seat 20 located at the front end is fixedly connected with the motor 14, and the output shaft end of the motor 14 is fixedly connected to the bidirectional threaded rod 21. The circumferential surface of the bidirectional threaded rod 21 is threadedly connected with the second extrusion block 19. The guide rod 22 penetrates the second extrusion block 19, and the second extrusion block 19 is slidably connected to the guide rod 22.

[0035] When working, the motor 14 is started, and the output shaft end of the motor 14 drives the bidirectional threaded rod 21 to rotate. Under the action of the guide rod 22, the second extrusion block 19 stably moves along the bidirectional threaded rod 21 toward or away from the second support platform 18. When the second extrusion block 19 approaches the second support platform 18, the front and rear ends of the suppository are squeezed simultaneously by the second extrusion block 19, so that the suppository is deformed, and the gas inside the suppository is squeezed. If the suppository leaks, it will be quickly detected.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
