Description

Technical Field

[0001] This utility model relates to a device for detecting the sound of opening a sealed bag on one side, belonging to the field of sealed bag sound detection technology. Background Technology

[0002] Resealable bags are widely used for the storage and protection of food, medicine, cosmetics, and other items, playing a crucial role in moisture prevention, leak prevention, and maintaining freshness. The airtightness of the resealable bag directly affects its protective effect; therefore, ensuring the effectiveness of the sealing strip is a critical step in its use.

[0003] Sealing bag design primarily relies on the convex and concave structure on the sealing strip to ensure airtightness. During production, the sealing effect of sealing bags is often tested using methods such as tensile testing, water immersion testing, or airtightness testing. However, these methods are inconvenient for users, so they mainly rely on visual inspection, touch, and sound to determine the effectiveness of the seal. While visual inspection and touch are often insufficient for intuitive and accurate confirmation of the seal, sound-based assessment provides more direct feedback on the seal and is convenient to operate. Therefore, the sound emitted when opening and closing the sealing bag can effectively help users confirm its effectiveness.

[0004] The sound of opening and closing the bag originates from the friction of the uneven structure of the sealing strip. Its acoustic characteristics (such as frequency and energy distribution) reflect the quality of the seal during closure. When the closing force is insufficient, the dominant frequency of the opening sound will drop from the normal value (approximately 2000Hz) to below 1500Hz, indicating a substandard seal. In some cases, the sealing strip may weaken its closure effect due to foreign object interference, aging, wear, etc. Therefore, an effective sound feedback mechanism can indicate to the user that the sealing strip has properly engaged, not only helping the user confirm the sealing status but also further enhancing the user experience of the resealable bag.

[0005] However, the existing technology does not fully consider the sound feedback needs of the sealed bag during customer use, nor does it provide an effective sealing strip opening and closing sound detection device to detect the sealing effect of the sealing strip. Therefore, this application proposes a sealing bag single-sided opening sound detection device. Utility Model Content

[0040] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0041] like Figures 1-7As shown, a device for detecting the sound of a sealed bag being opened on one side includes a fixed platform 1, a clamping mechanism 2, a bag opening mechanism 3, and a sound pickup device 4. The clamping mechanism 2 is slidably connected to the fixed platform 1 and includes two grippers 202, which are arranged opposite to each other. The bag opening mechanism 3 is slidably connected to the fixed platform 1 and is located above the clamping mechanism 2. The moving direction of the bag opening mechanism 3 is parallel to the moving direction of the clamping mechanism 2. The bag opening mechanism 3 includes an adjusting mounting base 301 and a straight rod 302, which is vertically mounted on the adjusting mounting base 301. The sound pickup device 4 is located below the clamping mechanism 2 and is used to collect the sound emitted by the sealed bag when it is opened.

[0042] Preferably, the clamping mechanism 2 further includes a clamping fixing seat 201, on which a vertical baffle 2011 is provided; the vertical baffle 2011 is parallel to the moving direction of the clamping mechanism 2, and the gripper 202 is connected to the clamping fixing seat 201. The gripper 202 includes a connecting rod 2021 and a movable clamping head 2022; the movable clamping head 2022 fixes the sealed bag by abutting against the vertical baffle 2011. Specifically, the movable clamping head 2022 is provided with a rubber pad layer, which fixes the sealed bag by elastically abutting against the vertical baffle 2011.

[0043] By setting up the clamping mechanism 2, the sealed bag can be stably fixed, providing a reliable foundation for subsequent bag opening operations. The design of the vertical baffle 2011 and the movable clamp 2022 ensures uniform clamping force, preventing damage to the sealed bag; and the rubber pad layer increases friction, improving clamping stability while preventing scratches on the surface of the sealed bag.

[0044] The bag opening mechanism 3 includes an adjustable mounting base 301 and a straight rod 302. The adjustable mounting base 301 includes a mounting plate 3011, an upper baffle 3012, a lower baffle 3013, and a guide post 3014. The upper baffle 3012 and the lower baffle 3013 are fixed on the mounting plate 3011. The guide post 3014 is fixed between the upper baffle 3012 and the lower baffle 3013. A straight rod mounting base 3015 is sleeved on the guide post 3014. The straight rod mounting base 3015 is provided with a locking mechanism, allowing the straight rod mounting base 3015 to slide along the guide post 3014 and be fixed in any position. The straight rod 302 is vertically mounted on the straight rod mounting base 3015. By setting the adjustable mounting base 301, the height of the straight rod 302 can be flexibly adjusted to accommodate sealing bags of different sizes, improving the versatility of the device.

[0045] Specifically, the adjustment mounting base 301 may also be equipped with a displacement sensor 303, which can measure the moving distance of the bag opening mechanism on the fixed platform to avoid collisions with other mechanisms.

[0046] The fixed platform 1 includes two uprights 101 and two horizontal plates 103. The horizontal plates 103 are fixedly connected to the two uprights 101. It also includes a placement platform 6, with the uprights 101 and the placement platform 6 fixedly connected via upright fixing seats 102. The placement platform 6 and the fixed platform 1 provide stable support.

[0047] A linear module 5 is further fixed above the horizontal plate 103. The linear module 5 includes a guide rail 501, and the bag opening mechanism 3 moves linearly along the guide rail 501. The linear module 5 can provide precise linear motion, ensuring the stability and consistency of the bag opening process.

[0048] The horizontal plate 103 is provided with a moving track 1031, and a slider is slidably connected to the moving track 1031. The clamping mechanism 2 is assembled on the slider. The design of the moving track 1031 and the slider allows for easy adjustment of the position of the clamping mechanism 2 to accommodate sealing bags of different sizes.

[0049] The linear module 5 is also equipped with drive mechanisms 7 on both sides, which are used to drive the bag opening mechanism 3 to move on the linear module 5. Sound-absorbing cotton is provided in the fixed platform 1, the linear module 5 and the column 101 to reduce the noise generated by the movement of the device and reduce the impact on the sound measurement of the sealed bag.

[0050] It also includes an operation panel 8, and the drive mechanism 7 and the sound pickup device 4 are electrically connected to the operation panel 8; the operation panel 8 includes a parameter adjustment module, a display module, and a sound detection module, and the sound detection module is used to detect whether the sound signal collected by the sound pickup device 4 is within a preset threshold range.

[0051] The drive mechanism 7 provides stable power to ensure the automation of the bag opening process, while the operation panel 8 offers an intuitive user interface for easy parameter setting and result viewing. The sound detection module automatically determines whether the bag opening sound is acceptable, improving detection efficiency.

[0052] The working principle of this utility model is as follows: Before testing, the operator can input the type and specifications (specifically including bag length) of the sealed bag to be tested through the parameter adjustment module on the operation panel 8, and set appropriate parameters such as bag opening speed and sound threshold.

[0053] Then the operator fixes the sealed bag to be tested on the jaws 202 of the clamping mechanism 2, and uses the movable jaws 2022 on the jaws 202 of the clamping mechanism 2 to clamp both ends of the sealed bag on the vertical baffle 2011 to ensure that the sealed bag is firmly fixed. The operator then adjusts the position of the sealed bag on the moving track 1031 by sliding the clamping mechanism 2 so that the sealed bag is in a straight and unfolded state.

[0054] The bag opening mechanism 3 is driven to move by the linear module 5. Specifically, as follows: Figure 7 As shown, a magnet is provided on the clamping mechanism 2 near the left end of the sealed bag. After the bag opening mechanism 3 senses the magnet, it travels a fixed distance and stops. At this time, the straight rod 302 is just above the insertable part of the sealed bag end. Then, the straight rod 302 of the bag opening mechanism 3 is inserted into the sealed bag. Except for the inserted part, the other parts of the sealing strip on the sealed bag remain closed. The sound pickup device 4 is placed on the fixed platform below the sealed bag, and the sound receiving component is close to the sealed bag to pick up the sound of the bag opening.

[0055] By operating the control panel 8, the bag-opening mechanism 3 is activated. The linear module 5 drives the bag-opening mechanism 3 to move at a preset speed. The straight rod 302 simulates the action of a human finger slicing open the sealed bag with a single finger, thus opening the sealed bag. Considering the sealing sections at both ends of the sealed bag, the travel distance is set to 80% of the preset bag length to avoid damage to the sealed bag. During the bag-opening process, the sound pickup device 4 collects the sound signal emitted by the sealed bag and transmits it to the sound detection module on the control panel 8. The sound detection module analyzes the collected sound signal, determines whether it is within a preset threshold range, and displays information such as the sound frequency through the display module, thereby determining whether the opening sound of the sealed bag is qualified.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
