Description

Technical Field

[0001] This utility model relates to a device for detecting the sound of a sealed bag closing, 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, especially in moisture prevention, leak prevention, and maintaining freshness. The airtightness of a resealable bag directly affects its protective effect; therefore, ensuring the complete closure of the seal is a critical step in its use. Current resealable bag designs typically rely on users to visually or tactilely determine if the seal is complete. However, users often find it difficult to intuitively and accurately confirm the seal's condition, especially in certain environments where the reliability of the seal is paramount for item preservation.

[0003] Resealable bags primarily rely on the textured structure of the sealing strip to ensure airtightness. In some cases, the sealing strip may weaken due to foreign object interference, aging, or wear. Without an effective audible feedback mechanism, users may not be able to detect whether the bag is fully closed, leading to a decrease in sealing effectiveness and compromising the protection of items. When the sealing strip is fully closed, it emits a distinct sound, serving as a feedback signal to the user that the strip has properly engaged. This sound is a crucial operational feedback mechanism in resealable bag design, not only helping users confirm the sealing status but also further enhancing the user experience.

[0004] However, existing technologies do not adequately consider the sound feedback needs of customers during the use of sealed bags, nor do they provide an effective sound detection device for opening and closing the sealing strip to detect the sealing effect of the sealing strip.

[0038] 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.

[0039] like Figures 1-7As shown, a sealing bag closing sound detection device includes a fixed platform 1, a clamping mechanism 2, a bag closing 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 closing mechanism 3 is slidably connected to the fixed platform 1 and is located above the clamping mechanism 2. The moving direction of the bag closing mechanism 3 is parallel to the moving direction of the clamping mechanism 2. The bag closing mechanism 3 includes a mounting plate 301, a guide post 302, and a clamping member 303. The guide post 302 is mounted on the mounting plate 301, and the clamping member 303 is sleeved on the guide post 302. A pressure-sensitive sensor is provided on the clamping member 303. The sound pickup device 4 is located below the clamping mechanism 2 and is used to collect the sound emitted by the sealing bag when it is closed.

[0040] 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, the gripper 202 is connected to the clamping fixing seat 201, and the gripper 202 includes a connecting rod 2021 and a movable gripper 2022; the movable gripper 2022 fixes the sealed bag by abutting against the vertical baffle 2011; the clamping fixing seat 201 is also provided with a sensing plate 203.

[0041] The mounting plate 301 is provided with a movable plate 3011, which can slide up and down along the mounting plate 301. The movable plate 3011 is provided with a locking mechanism 3012, so that the movable plate 3011 can slide on the mounting plate 301 and be fixed in any position. A limiting plate 3013 is provided above the mounting plate 301. The guide post 302 is vertically installed on the movable plate 3011, and a limiting block 304 is provided at the end of the guide post 302. A knob 305 is provided on the limiting block 304, which can adjust the clamping member 303 to make relative movement. A proximity switch 306 is installed on the mounting plate 301.

[0042] The design of the movable plate 3011 and the locking mechanism 3012 allows the height of the guide post 302 to be adjusted to accommodate sealing bags of different sizes. The clamping members 303 can move relative to the guide post 302. By controlling the spacing of the clamping members 303, it can accommodate sealing bags of different thicknesses, improving the versatility and flexibility of the device. The proximity switch 306 is used to sense the position of the sensing plate 203 on the clamping base 201, thereby stopping the movement.

[0043] Preferably, the clamping member 303 is detachably provided with an elastic anti-slip component. The elastic anti-slip component can increase the friction between the clamping member 303 and the sealing bag, prevent the sealing bag from slipping during the closing process, and ensure the stability and reliability of the bag closing action; at the same time, the elastic material is relatively soft and will not cause damage to the sealing bag or cause indentations.

[0044] 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 101 fixing seats.

[0045] Furthermore, a linear module 5 is fixed above the horizontal plate 103. The linear module 5 includes a guide rail 501, and the bag-closing 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-closing process.

[0046] The horizontal plate 103 is equipped with a moving track 1031, and a slider is slidably connected to the moving track 1031. The clamping mechanism 2 is mounted 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. Sound-absorbing cotton is installed inside the fixed platform 1, the linear module 5, and the column 101 to reduce the noise generated by the movement of the device and minimize the impact on the sound measurement of the sealing bags.

[0047] 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.

[0048] The drive mechanism 7 provides stable power to ensure the automation of the bag-closing process, while the operation panel 8 offers an intuitive interface for easy parameter setting and result viewing. The sound detection module automatically determines whether the bag-closing sound is acceptable, improving detection efficiency.

[0049] 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.

[0050] Then the operator fixes the sealed bag to be tested onto 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 onto the vertical baffle 2011 to ensure that the sealed bag is firmly fixed. By sliding the clamping mechanism 2, the operator adjusts its position on the moving track 1031 so that the sealed bag is in the unfolded state.

[0051] Cut open the sealing strip on the sealed bag, and then adjust the clamping pressure of the bag closing mechanism 3 so that the clamping member 303 clamps the sealing strip with appropriate pressure. 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 opening the bag.

[0052] By operating the control panel 8, the bag-closing mechanism 3 is activated. The linear module 5 drives the bag-closing mechanism 3 to move at a preset speed. The clamping member 303 simulates the action of a human finger closing the bag with two fingers, thereby sealing the bag. The bag-closing mechanism 3 moves a distance of 80% of the bag length pre-input into the control panel 8. Traveling beyond the bag length may cause collisions with other mechanisms and damage. During the bag-closing 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 bag-closing sound is acceptable.

[0053] 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.
