Description

Sealed bag unilateral bag opening sound detection device Technical Field The utility model relates to a sealing bag single-side bag opening sound detection device, and belongs to the technical field of sealing bag sound detection. Background The sealing bag is widely applied to storage and protection of foods, medicines, cosmetics and other articles, and plays an important role in dampproofing, leakage prevention, article freshness keeping and the like. The tightness of the sealing bag directly influences the protection effect, so that the effectiveness of the sealing strip is ensured to be a key link in the using process. The sealing bag is designed mainly by means of concave-convex structures on sealing strips to ensure air tightness, and in the production process, methods such as tensile test, water immersion detection or air tightness detection are adopted for detecting the sealing effect of the sealing bag. However, the above detection method is inconvenient for the user, so that whether the seal is effective is mainly judged by visual inspection, hand feeling and sound. The visual inspection and the hand feeling judgment are difficult to intuitively and accurately confirm the sealing state, and the sound judgment can intuitively feed back the sealing state and is convenient to operate, so that a user can be well helped to confirm whether the sealing state of the sealing bag is effective by sound when the sealing bag is opened or closed. The sound of opening and closing the bag is generated by friction sound of concave-convex structures of the sealing strips, and the acoustic characteristics (such as frequency and energy distribution) can reflect the occlusion quality during closing. When the closing bite force is insufficient, the main frequency of the opening sound can be reduced from a normal value (about 2000 Hz) to below 1500Hz, which indicates that the sealing does not reach the standard. In some cases, the sealing strip may have a reduced closure effect due to foreign matter interference, aging, wear, and the like. Therefore, the effective sound feedback mechanism can prompt the user that the sealing strips are correctly meshed, thereby not only helping the user confirm the sealing state, but also further improving the use experience of the sealing bag. However, in the prior art, the acoustic feedback requirement of the sealed bag during the use of the sealed bag by the customer is not fully considered, and an effective sealing strip opening and closing acoustic detection device is not provided to detect the sealing effect of the sealing strip, so the application provides a sealed bag single-side bag opening acoustic detection device. Disclosure of utility model The utility model aims to provide a sealed bag unilateral bag opening sound detection device which solves the technical problems in the prior art. The utility model provides a single-side bag opening sound detection device of a sealed bag, which comprises a fixed table, a clamping mechanism, a bag opening mechanism and a sound pickup device; The clamping mechanism is in sliding connection with the fixed table and comprises two clamping jaws, and the two clamping jaws are oppositely arranged; The bag opening mechanism is in sliding connection with the fixed table, the bag opening mechanism is positioned above the clamping mechanism, the moving direction of the bag opening mechanism is parallel to that of the clamping mechanism, the bag opening mechanism comprises an adjusting installation seat and a straight rod, and the straight rod is vertically installed on the adjusting installation seat; The sound pickup device is arranged below the clamping mechanism and is used for collecting sound emitted by the sealing bag when the sealing bag is opened. Compared with the prior art, the technical scheme provided by the utility model has the beneficial effects that the sealing bag can be stably fixed by arranging the clamping mechanism, so that a reliable basis is provided for subsequent bag opening operation. The sound pickup device is arranged, so that sounds emitted during bag opening can be accurately collected, and data support is provided for subsequent sound detection. On the basis of the technical scheme, the utility model can be improved as follows. The clamping mechanism further comprises a clamping fixing seat, a vertical baffle is arranged on the clamping fixing seat, the vertical baffle is parallel to the moving direction of the clamping mechanism, the clamping jaw is connected with the clamping fixing seat and comprises a connecting rod and a movable clamping head, and the movable clamping head is abutted with the vertical baffle to fix the sealing bag.
