[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] Reference Figures 2 to 4The preferred embodiment of the utility model provides a differential pressure sealing detection device for detecting the sealing performance of the bottle body 2 after packaging, comprising:

[0031] A support base 1, used for placing a bottle body 2;

[0032] The sealing cover 3 is arranged on the support base 1 and is used to cover the bottle body 2 and seal with the support base 1;

[0033] A vacuum mechanism, used to extract air from the sealing cover 3 in a sealed state;

[0034] The differential pressure detection device includes a contrast module with a contrast chamber, which is used to detect the pressure inside the sealing cover 3 and the pressure difference of the contrast module under vacuum state; the volume of the contrast chamber is the difference between the inner volume of the sealing cover 3 and the volume of the bottle body 2.

[0035] It can be understood that after the bottle body 2 to be tested is placed on the support seat 1, a sealing cover 3 is provided to seal with the support seat 1, and the air in the sealing cover 3 in a sealed state is extracted by a vacuum mechanism, and the differential pressure detection device performs detection. The differential pressure sealing detection device detects the pressure in the sealing cover 3 and the pressure difference of the comparison module under a vacuum state by setting a differential pressure detection device. The volume of the comparison cavity of the comparison module is the difference between the volume of the inner cavity of the sealing cover 3 and the volume of the bottle body 2, that is, when the bottle body 2 does not leak, the internal spaces of the two have the same volume, and the internal pressures of the two are the same after vacuuming, so that whether the bottle body 2 is qualified can be judged according to the pressure difference between the two, thereby avoiding the adverse consequences such as inaccurate detection structure caused by using a leaking sample bottle as a reference for measurement, and the detection result is accurate, which is suitable for online mass production of packaging bottles for food and medicine.

[0036] The differential pressure detection device includes a mounting seat 12 disposed on one side of the support seat 1, a comparison cover 13 is disposed on the mounting seat 12, the comparison cover 13 is sealed and connected to the mounting seat 12, and the vacuum mechanism is also used to extract the air in the comparison cover 13 in a sealed state;

[0037] Specifically, the support seat 1 and the mounting seat are respectively provided with vertically penetrating channels, the vacuum mechanism is connected to the channel of the support seat 1 through a first pipeline, and the vacuum mechanism is connected to the channel of the mounting seat 12 through a second pipeline. The differential pressure detection device also includes a detection pipeline 14 connected to the first pipeline and the second pipeline, and a differential pressure transmitter 15 is arranged on the detection pipeline 14. The differential pressure transmitter 15 is used to detect the pressure difference between the pressure in the sealing cover 3 and the comparison cover 13 and feed it back to the corresponding equipment for processing.

[0038] In this embodiment, the differential pressure sealing detection device also includes a lifting mechanism connected to the support seat 1, which is used to control the distance between the sealing cover 3 and the support seat 1. The differential pressure sealing detection device controls the distance between the sealing cover 3 and the support seat 1 by setting the lifting mechanism, so that the bottle body 2 has a moving space to be placed on the support seat 1, and after the bottle body 2 is placed, the sealing cover 3 is controlled to move and seal with the support seat 1. The differential pressure sealing detection device can quickly achieve sealing and unsealing, and then realize online detection of the sealing performance of the bottle body 2, and is suitable for mass production of bottle packaging such as food and medicine.

[0039] In this embodiment, the sealing detection mechanism includes a rotating mechanism, a supporting seat 1, a mounting seat 12, a sealing cover 3 and a lifting mechanism are respectively arranged on the rotating mechanism, the lifting mechanism includes a lifting rod 4 connected to the rotating mechanism along a vertical sliding manner and a lifting component 6 fixedly arranged on the lifting rod 4, and a lifting cam 8 is fixedly arranged on one side outside the rotating mechanism, which is used to make the lifting component 6 cooperate with the lifting cam 8 when the rotating mechanism drives the lifting mechanism to rotate circumferentially to a preset position, and then drive the sealing cover 3 to rise through the lifting rod 4. By setting a rotating mechanism and designing the cooperation structure of the lifting mechanism and the lifting cam 8, when the rotating mechanism rotates to the target position, the lifting block cooperates with the lifting cam 8 to move to the highest position through the lifting The lifting rod 4 drives the sealing cover 3 to rise, and the bottle body 2 can be placed and taken out at the target position. Outside the target position, the lifting block disengages from the cooperation with the lifting cam 8 and gradually lowers its position so that the sealing cover 3 is pressed on the support seat 1 under its weight and the weight of the lifting mechanism to achieve sealing; by evenly arranging multiple support seats 1 along the circumference of the rotating mechanism, the number of lifting mechanisms, the number of sealing covers 3, etc. are matched with the number of support seats 1, the bottle body 2 is taken and placed at the target position, and the bottle body 2 outside the target position is in a sealed state for sealing detection. After each bottle body 2 rotates one circle of the rotating mechanism, the pressure detection is completed, so as to realize fast and continuous online detection, make full and reasonable use of equipment space, and greatly improve production capacity.

[0040] Specifically, the rotating mechanism includes a coaxially arranged rotating seat, a first rotating disk 5 and a second rotating disk 7, the support seat 1 and the differential pressure detection device are arranged on the rotating seat, and the lifting mechanism is respectively penetrated through the first rotating disk 5 and the second rotating disk 7; the rotating seat, the first rotating disk 5 and the second rotating disk 7 rotate based on the same axis.

[0041] In this embodiment, a sealing ring 31 is embedded in one end of the sealing cover 3 facing the support seat 1. When the sealing cover 3 is matched with the support seat 1, the sealing ring 31 abuts against the surface of the support seat 1 to form a sealing match.

[0042] Among them, a groove for embedding a sealing ring 31 is opened at one end of the sealing cover 3 facing the support seat 1, and a groove 32 is processed on the inner wall of the groove. The groove 32 can make the inner wall of the groove and the sealing ring 31 fit better and has an axial positioning function to prevent the sealing ring 31 from falling off during the reciprocating movement of the sealing cover 3, resulting in sealing failure.

[0043] In this embodiment, the differential pressure sealing detection device also includes a cleaning mechanism arranged near the support seat 1, which is used to remove materials leaked to the support seat 1. When the bottle body 2 leaks, the negative pressure in the sealing cover 3 during the detection will cause the liquid material in the bottle body 2 to flow out and finally fall on the surface of the support seat 1. Cleaning by the cleaning mechanism can avoid shutdown for cleaning and influence on subsequent bottle bodies 2, avoid affecting the detection results, and greatly improve production efficiency and capacity.

[0044] Specifically, the cleaning mechanism includes an air nozzle assembly 9 arranged obliquely above the support seat 1, and the air outlet end of the air nozzle assembly 9 is arranged toward the surface of the support seat 1. The cleaning mechanism also includes a collecting assembly 10 arranged obliquely below the support seat 1 and arranged opposite to the air nozzle assembly 9. The air nozzle assembly 9 is connected to the air source to maintain the output airflow to the surface of the support seat 1. The collecting assembly 10 includes a collecting frame, and the air nozzle assembly 9 blows the material on the surface of the support seat 1 into the collecting frame for collection;

[0045] Furthermore, the cleaning mechanism further includes a suction tube 11, the inlet end of which is arranged at the top of the inner cavity of the collecting component 10, and the suction tube 11 is arranged through the air nozzle component 9 and the air nozzle component 9 provides negative pressure so that the suction tube 11 sucks out the material exceeding the preset liquid level in the collecting component 10. The storage capacity of the collecting frame is limited. In order to avoid affecting the machine, the suction tube 11 is arranged to extract the liquid exceeding the upper limit of the maximum liquid level in the collecting frame. The suction tube 11 can act on the suction tube 11 through the negative pressure generated by the working state of the air nozzle component 9 so that it has suction force to suck out the liquid;

[0046] Furthermore, the support seat 1 rotates with the rotating mechanism, and the collecting component 10 is fixedly arranged, and the two cannot contact each other. A boss is formed by circumferentially extending on the top of the outer wall of the support seat 1, and one side of the collecting component 10 is arranged under the boss to ensure the collection effect of the collecting component 10 and prevent the material from being blown off or hanging along the outer wall of the support seat 1.

[0047] On the other hand, this embodiment also provides a medicine bottle packaging device, which is equipped with the above-mentioned differential pressure sealing detection device.

[0048] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
