Description

Technical Field

[0001] This utility model relates to the field of food filling and testing technology, and in particular to a membrane-free testing device based on bottled probiotic packaging. Background Technology

[0002] Currently, in the packaging and production of bottled probiotics and other liquid foods, the bottle opening typically needs to be heat-sealed or film-sealed after filling to ensure the product's airtightness and hygiene. However, most existing production lines lack online detection devices for the integrity of the sealing film. When the sealing machine malfunctions or the film is missing, some products may directly enter the capping and packaging processes without being sealed, resulting in defective products without film being released. Such problems not only affect the product's appearance and quality but may also lead to bacterial contamination, leakage, or a shortened shelf life.

[0003] Traditional seal inspection relies heavily on manual sampling or single photoelectric detection methods, which suffer from low efficiency, high false positive rates, and the inability to achieve dynamic correction. When the bottle position shifts or the reflective properties of the seal change, single-point sensors are prone to false detections, affecting production continuity and inspection reliability. Especially on high-speed filling production lines, where bottle movement distances are small and cycle times are fast, existing detection devices struggle to balance detection accuracy and response speed, failing to meet the demands of real-time inspection. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a membrane-free detection device based on bottled probiotic packaging.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A membrane-free detection device based on bottled probiotic packaging includes a support and a controller. One end of the support is equipped with a mounting rod, and the mounting rod is fitted with a mounting sleeve and two mounting seats. A photoelectric sensor is mounted on one side of the mounting seat via a reciprocating drive assembly, and one side of the mounting sleeve is connected to the two mounting seats via a telescopic component.

[0007] Preferably, the mounting sleeve is mounted on the mounting rod by fastening bolts.

[0008] Preferably, the mounting base has a through hole, the inner diameter of which is adapted to the outer diameter of the mounting rod, and an electromagnetic component is provided on the inner wall of the mounting base to control the locking or releasing action of the mounting base.

[0009] Preferably, a fixed seat is provided on one side of the outer wall of the mounting sleeve, and a connecting wing is provided on one side of the mounting seat. The two ends of the telescopic component are respectively connected to the fixed seat and the connecting wing.

[0010] Preferably, the photoelectric sensor is slidably connected to the reciprocating drive assembly.

[0011] Preferably, the mounting sleeve is located between two mounting bases.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention achieves intelligent adjustment and dynamic calibration of the photoelectric sensor's detection position by incorporating an adjustable-spacing dual-mount structure on a support, along with telescopic components, electromagnetic components, and a reciprocating drive assembly. This structure automatically adjusts the detection distance based on the sealing position of probiotic bottles of different sizes, and drives the photoelectric sensor to rapidly reciprocate in case of detection anomalies, accurately distinguishing between cases of no film and bottle misalignment, thereby significantly improving detection accuracy and stability. The device is compact, easy to adjust, and highly adaptable, and can be directly integrated into existing filling production lines, exhibiting a high level of automation and broad industrial application prospects.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1 to 3 A membrane-free detection device based on bottled probiotic packaging includes a support 1 and a controller. One end of the support 1 is equipped with a mounting rod 2, and the mounting rod 2 is fitted with a mounting sleeve 7 and two mounting seats 3. A photoelectric sensor 8 is mounted on one side of the mounting seat 3 through a reciprocating drive assembly 10. One side of the mounting sleeve 7 is connected to the two mounting seats 3 through a telescopic component 5.

[0020] The distance between the two mounting seats 3 can be adjusted by extending and retracting the telescopic component 5. When bottled probiotic products of different specifications or with different spacing pass through the detection area on the production line, the operator can change the distance between the two mounting seats 3 by controlling the telescopic component 5 according to the bottle diameter and bottle spacing, so that the detection position of the photoelectric sensor 8 always corresponds to the center position of the bottle opening. This structure can adapt to the sealing detection needs of various bottle types, eliminating the need for frequent replacement of mounting brackets, thereby improving the versatility and work efficiency of the device.

[0021] During the detection process, photoelectric sensor 8 emits a detection beam, such as infrared or visible light. The beam is reflected or transmitted through the bottle opening area and returns to the receiver. When the seal on the bottle opening is intact, the seal surface generates a specific reflection signal on the beam. Photoelectric sensor 8 can receive this reflection signal and output a "seal present" status signal. If the bottle opening has no seal or the seal is missing, the beam will penetrate directly or reflect abnormally, and the receiver cannot detect a valid reflection signal. In this case, photoelectric sensor 8 outputs an abnormal "seal absent" status signal. The controller determines the current seal status of the bottle based on this signal status and can further link the production line alarm or rejection mechanism to achieve real-time detection and rejection.

[0022] When the photoelectric sensor 8 detects an abnormal signal, the system does not immediately classify it as a product without a film. Instead, the reciprocating drive assembly 10 drives the photoelectric sensor 8 to perform a short, small-amplitude, rapid reciprocating movement, causing the detection beam to scan again at different positions in the bottle opening area. If no reflection signal is detected during the repeated detection, the bottle is determined to be a defective product without a film. If the detection signal returns to normal during the reciprocating movement, it indicates that the abnormality is due to an error caused by a slight offset or incorrect posture of the bottle. Through this secondary verification process, the system can effectively distinguish between two abnormal situations: genuine lack of film and positional deviation, thereby significantly improving detection accuracy and reliability.

[0023] The entire testing process is automatically coordinated and executed by the controller. The telescopic component 5 is responsible for structural adjustment, the photoelectric sensor 8 is responsible for sealing film detection, and the reciprocating drive component 10 realizes dynamic verification. The three work together to achieve continuous, accurate, and stable testing of bottled probiotic sealing films on high-speed production lines, ensuring product quality and preventing defective products without films from flowing into subsequent capping processes.

[0024] As a preferred embodiment of this utility model, the telescopic component 5 can take various forms to meet the installation requirements and usage environment of different production lines. For example, the telescopic component 5 can be an electric telescopic rod, which realizes the telescopic action by driving the lead screw mechanism with a built-in motor. It has the advantages of compact structure, precise control, and convenient adjustment, and is suitable for automated production lines that require frequent adjustment of the mounting seat spacing.

[0025] In another alternative, the telescopic component 5 can be a hydraulic or pneumatic telescopic rod structure. The piston reciprocates via pressure changes in hydraulic oil or compressed air, enabling rapid adjustment of the distance between the mounting seats 3. This structure features fast response, high thrust, and strong adaptability, making it particularly suitable for production line environments with frequent changes in bottled product specifications and fast work cycles.

[0026] In a preferred embodiment of this utility model, the mounting sleeve 7 is mounted on the mounting rod 2 by fastening bolts 9.

[0027] In a preferred embodiment of this utility model, the mounting base 3 has a through hole, the inner diameter of which matches the outer diameter of the mounting rod 2, allowing the mounting base 3 to slide and adjust its position along the direction of the mounting rod 2. An electromagnetic component 11 is provided on the inner wall of the mounting base 3. The electromagnetic component 11 can be an electromagnet or a coil magnetic attraction assembly. The electromagnetic component 11 controls the locking or releasing action of the mounting base 3. After the position of the mounting base 3 is adjusted by the telescopic component 5, the electromagnetic component 11 is energized, generating a magnetic field that forms a magnetic attraction with the metal sidewall of the mounting rod 2, causing the mounting base 3 to be firmly attached and positioned at the set position. At this time, the relative movement between the mounting base 3 and the mounting rod 2 is locked, effectively preventing the mounting base from shifting due to vibration or impact during operation, thus ensuring the stability of the detection position of the photoelectric sensor 8. When it is necessary to readjust the position of the mounting base 3, simply cut off the power to the electromagnetic component 11, the magnetic attraction is released, and the mounting base 3 can slide freely along the mounting rod 2 again.

[0028] In a preferred embodiment of the present invention, a fixing seat 6 is provided on one side of the outer wall of the mounting sleeve 7, a connecting wing 4 is provided on one side of the mounting seat 3, and the two ends of the telescopic component 5 are respectively connected to the fixing seat 6 and the connecting wing 4.

[0029] In a preferred embodiment of this utility model, the photoelectric sensor 8 is slidably connected to the reciprocating drive assembly 10. The photoelectric sensor 8 is mounted on the sliding end or sliding seat of the reciprocating drive assembly 10. This connection method enables short-stroke reciprocating movement during the detection process. The sliding connection can adopt structures such as slide rails, slide grooves, sliders, or guide rods to ensure that the photoelectric sensor 8 moves smoothly in a predetermined direction during reciprocating motion, avoiding detection errors caused by offset or vibration.

[0030] The reciprocating drive assembly 10 can adopt an electric push rod structure, an electromagnetic push-pull assembly, a pneumatic cylinder, a miniature cylinder structure, etc.

[0031] In a preferred embodiment of the present invention, the mounting sleeve 7 is located between the two mounting bases 3.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
