Description

Technical Field

[0001] The utility model relates to the technical field of bottle mouth sealing detection, in particular to a bottle mouth sealing detection device. Background Art

[0002] As an important part of packaging, the design and function of bottle caps are directly related to product protection, quality preservation and user experience. With the development of the packaging industry, the requirements for bottle caps are getting higher and higher. Not only must their sealing performance be ensured, but also their opening convenience, aesthetics and innovation must be considered. Therefore, bottle cap designers are constantly seeking innovation in design to meet diverse market demands.

[0003] In the design of bottle caps, sealing performance is a core indicator, which is directly related to the shelf life and safety of the product. Bottle caps with good sealing performance can effectively prevent the entry of outside air, moisture, etc., thereby protecting the contents from contamination and deterioration. At the same time, sealing performance is also the key to evaluating whether the bottle cap is qualified or not. Therefore, the detection of the sealing performance of the bottle cap is particularly important.

[0004] However, traditional sealing detection equipment is usually bulky and complicated to operate. It not only takes up a large space, but also has a slow detection speed and cannot meet the needs of fast and efficient production. In addition, these devices can usually only perform batch inspections on bottle caps on the entire production line. The sealing inspection of individually drawn bottle caps is inefficient and cannot provide test results quickly, which to a certain extent affects production efficiency and quality control.

[0005] Therefore, a portable bottle mouth sealing detection device has emerged. The bottle mouth sealing detection device has the characteristics of small size and easy operation. It can be used alone for rapid detection. It can not only save space, but also reduce energy consumption, improve detection speed, and make the production process more efficient and convenient.

[0006] Existing bottle mouth sealing detection equipment is generally improved to address the problems of high power consumption, long startup time, complex structure, inconvenience in carrying and slow detection results and long process when spot checking a single bottle cap. For example, a bottle mouth sealing detection equipment disclosed in the authorized Chinese patent CN216349421U can be used in combination with structures such as a compression rod, a hollow tube, a detection head, a pressure detection gauge, a push block, a spring return member, a first handle, a second handle, a sealing gasket, a connecting channel, a buckle, a piston, a cavity, an opening and an air duct. The structure is simple and easy to carry, which is convenient for detection personnel to perform corresponding detection anytime and anywhere. The detection operation only needs to push the compression rod to observe the value change of the pressure detection gauge to know whether the bottle cap is sealed or not, which is very simple.

[0007] However, when the bottle mouth sealing detection device in the above cited document is in use, when the compression rod compresses the air in the cavity, the air in the cavity gives a thrust to the compression rod, and the buckle is installed on the groove of the first handle, fixing the relative distance between the first handle and the second handle. The operator no longer needs to clamp the first handle and the second handle with both hands, so that the compression rod will not be pushed away by the air in the cavity, so as to facilitate the operator to read the data on the pressure detection gauge. However, the operator must operate with both hands, that is, one hand needs to continuously apply force to fix the compression rod, while the other hand needs to operate the buckle for installation. The operator needs to divide his attention to maintain the position of the compression rod and to operate the buckle at the same time, and at the same time, the air in the cavity needs to keep applying a thrust to the compression rod. According to common sense, this The thrust should be sufficient to overcome the friction between the ring buckle and the groove of the first handle, so that the ring buckle can be firmly installed on the first handle. However, in fact, this thrust is not enough to ensure the firm installation of the ring buckle, especially when operated by a staff with less strength. Since the design of the compression rod does not fully consider the balance between the air thrust and the friction force, the ring buckle cannot be stably fixed on the first handle. If the operator suddenly loses force during the operation of the ring buckle, and fails to press the compression rod in time when the compressed air is released and rebounds, the compressed air in the cavity will be quickly released, generating a reverse thrust. This sudden rebound force will not only cause harm to the operator, but may also damage the equipment or affect the accuracy of the test results. Utility Model Content

[0049] The working principle of the above embodiment is:

[0050] When the bottle cap needs to be inspected, hold the No. 1 handle 7 and the No. 2 handle 8 with both hands and squeeze them in opposite directions, push the piston rod located in the hollow tube 1 at one end of the compression push rod 5 to move, and make the compression push rod 5 compress the air in the hollow tube 1, and drive the moving plate 9082 to move at the same time. Due to the characteristics of the arc surface of the arc-shaped clamping block 9072, one side of the arc surface will convert the horizontal movement force into vertical movement force when it fits in the limit groove 909, and drive the insertion rod 9071 to move in the direction close to the No. 2 handle 8, and push the convex connecting block 9032 to move under the thrust during the movement. Since the convex connecting block 9032 is fixed to the support rod, the outer side of the support rod is slidably connected to the inner side of the support block 9022, and drives the circular block to move close to the No. 2 handle 8. Move in the direction of handle No. 2 8, when the two concave limit blocks 9033 approach each other, the No. 2 spring return member 9034 contracts elastically. At the same time, the compression push rod 5 is gradually pushed into the inner side of the hollow tube 1, so that the air in the hollow tube 1 gives the compression push rod 5 a reverse thrust, driving the No. 1 handle 7 to move in the direction away from the pressure detection gauge 2, and driving the movable plate 9082 to move, so that the limit groove 909 can fit tightly with one side of the plane of the arc-shaped clamping block 9072, so that the compression push rod 5 will not be pushed back by the air in the hollow tube 1, and the operator does not need to clamp the No. 1 handle 7 and the No. 2 handle 8 with both hands, so that the compression push rod 5 will not be pushed away by the air in the hollow tube 1, which is convenient for the operator to read the data on the pressure detection gauge 2.

[0051] Compared with the prior art: the bottle mouth sealing detection equipment, through the mutual cooperation between the pressure detection gauge 2, the detection head 3, the No. 1 spring return member 4, the compression push rod 5, the push block 6, the No. 1 handle 7, the No. 2 handle 8 and the adjustable limit fixing mechanism 900 on the hollow tube 1, can provide an adjustable limit positioning function, effectively improve the safety of operation, and can effectively prevent the operator from being injured by the reverse thrust generated by the release of compressed air due to improper force release during the operation of the ring buckle.
