[0026] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-5 As shown, this embodiment provides a bagging device for sampling test strips of trace explosives, including: a workbench, a bagging box 10, a bag-removing clamp, and a gripper 30. The bagging box 10 is connected to the workbench, and a bag-removing opening 111 is provided at the bottom of the bagging box 10. The bag-removing clamp is movably connected to the workbench. The bag-removing clamp moves to remove the packaging bag 1 from the bag-removing opening 111 and open the packaging bag 1. The gripper 30 is movably connected to the workbench, and the gripper 30 moves to be suitable for placing the sampled test strip into the packaging bag 1.

[0028] In some embodiments, the workbench serves as the basic support structure of the entire bagging device. The workbench can provide a platform for the installation and movement of other components, ensuring that each component can maintain a relatively stable positional relationship during operation and achieve orderly actions. The bagging box 10 is connected to the workbench. The bottom of the bagging box 10 is provided with a bag-removing opening 111. The bagging box 10 is used to store the packaging bag 1. The bag-removing opening 111 allows the bag-removing clamp to smoothly remove the packaging bag 1 from the box. The bag-removing clamp is movably connected to the workbench. The bag-removing clamp can move under the constraint of the workbench to remove the packaging bag 1 from the bag-removing opening 111 at the bottom of the bagging box 10. After removing the packaging bag 1, the packaging bag 1 is opened to prepare for the insertion of the test strip. The gripper 30 is movably connected to the workbench. With the help of the moving function, the gripper 30 can accurately place the already spotted test strip into the already opened packaging bag 1, completing the bagging process of the test strip.

[0029] It is understandable that the packaging bag 1 has an opening on one side. During bagging, firstly, the bag-removing clamp moves on the worktable to the bag-removing opening 111 of the bagging box 10, and removes the packaging bag 1 from the bagging box 10 through a specific mechanical structure or suction. Then, the bag-removing clamp moves further, using its own structure to open the packaging bag 1, so that the packaging bag 1 is in a state where test strips can be placed. At the same time, the gripper 30 grabs the test strip that has been sampled and moves it on the worktable to one side of the opened packaging bag 1. Then, the gripper 30 continues to move to put the test strip into the packaging bag 1, thus completing a complete bagging operation.

[0030] It is worth mentioning that the worktable provides a moving track and reference for the bag-retrieving fixture and the gripper 30, enabling them to move precisely along a predetermined path and position. The bag-filling box 10, serving as a storage unit for the packaging bag 1, has a bag-retrieving opening 111 designed to match the movement of the bag-retrieving fixture, ensuring that the fixture can smoothly remove the packaging bag 1. The bag-retrieving fixture, through its own movement and motion design, achieves the functions of bag retrieval and opening, while the gripper 30 focuses on the grasping and placement of test strips. The two work together to complete the bagging task.

[0031] The bagging device for trace explosive sampling test strips according to this utility model automates the bagging process, greatly shortens the time required for each bagging cycle, and significantly improves bagging efficiency to meet the demand for rapid bagging of test strips in large-scale production and testing. Moreover, it can reduce the impact of human factors on the bagging process and avoid problems such as damage to the packaging bag 1 and inaccurate placement of the test strips caused by improper manual operation, thereby ensuring bagging quality and improving the product qualification rate.

[0032] It is worth mentioning that manual bagging requires operators to perform repetitive labor for a long time, which can easily lead to fatigue and operational errors. The bagging device of this application frees operators from tedious bagging work, reduces labor intensity, and also reduces potential safety hazards caused by personnel fatigue.

[0033] Of course, the bagging device can ensure that the bagging process of each packaging bag 1 is consistent, improve the standardization of bagging, and facilitate the subsequent management and testing of test strip samples.

[0034] According to some embodiments of the present invention, the bag-removing clamp includes a first suction cup 21 and a second suction cup 22. The first suction cup 21 is movably connected to the worktable, and a first suction port is provided on the top of the first suction cup 21. The second suction cup 22 is connected to the worktable, and a second suction port is provided on the bottom of the second suction cup 22. The first suction cup 21 moves to the bottom of the second suction cup 22 after the first suction port engages with the bottom of the packaging bag 1, so that the second suction port engages with the top of the packaging bag 1, thereby opening the packaging bag 1.

[0035] In some embodiments, the bag box 10 and the bag retrieval clamp are both located on one side of the workbench width direction, and the gripper 30 is located on the other side of the workbench width direction. The bag box 10 contains a plurality of packaging bags 1, and the opening of each packaging bag 1 is set facing the gripper 30.

[0036] During operation, the first suction cup 21 moves along the length direction to below the bag box 10, and then moves along the height direction to contact the packaging bag 1. Under the suction force of the first suction cup 21, the first suction cup 21 can stably adhere to the packaging bag 1. Then, the first suction cup 21 moves away from the bag box 10 along the height direction to remove the packaging bag 1. Immediately afterwards, the first suction cup 21 moves along the length direction to below the second suction cup 22, and then moves along the height direction toward the second suction cup 22 so that the second suction cup 22 contacts the top of the packaging bag 1. Then, the first suction cup 21 moves away from the second suction cup 22 along the height direction. At this time, the packaging bag 1 can be opened under the action of the first suction cup 21 and the second suction cup 22.

[0037] The gripper 30 moves along the length direction to move the sampled test strip to face the opening of the packaging bag 1. Then, the gripper 30 moves along the width direction toward the packaging bag 1 and places the test strip inside the packaging bag 1. Finally, the gripper 30 releases the gripper from the test strip and moves away from the packaging bag 1 in the width direction to reset, thus completing the bagging of the test strip.

[0038] Therefore, by using the first suction cup 21 and the second suction cup 22 to adsorb the bottom and top of the packaging bag 1 respectively, the bag retrieval and opening of the packaging bag 1 can be accurately and stably controlled, avoiding the problem of damage to the packaging bag 1 or failure to open normally due to inaccurate gripping position, and improving the success rate of bag retrieval and opening.

[0039] According to some embodiments of the present invention, the bag-removing clamp further includes two fixing claws 23, which are respectively connected to the worktable and are located on both sides of the second suction cup 22 in the length direction. The two fixing claws 23 are respectively adapted to clamp the two sides of the opening of the packaging bag 1 when the second suction port is engaged with the top of the packaging bag 1.

[0040] In some embodiments, the bag-removing clamp includes a first suction cup 21 and a second suction cup 22, as well as two fixing claws 23. The two fixing claws 23 are respectively connected to the worktable and are fixed in position. At the same time, the two fixing claws 23 are respectively located on both sides of the second suction cup 22 in the length direction. When the second suction port engages with the top of the packaging bag 1, that is, when the second suction cup 22 adsorbs the top of the packaging bag 1, the two fixing claws 23 start to move and clamp the two sides of the opening of the packaging bag 1 respectively.

[0041] Understandably, when the second suction port engages with the top of the packaging bag 1, the two retaining claws 23 clamp the two sides of the opening of the packaging bag 1 respectively, and then the first suction cup 21 moves away from the second suction cup 22 in the height direction to open the packaging bag 1.

[0042] It is worth noting that by clamping the two sides of the opening of the packaging bag 1 with the two fixing claws 23 respectively, the opening of the packaging bag 1 can be prevented from being too large when it is opened, thereby preventing the packaging bag 1 from being torn or damaged during the opening process.

[0043] According to some embodiments of the present invention, the bag box 10 includes a bottom plate 11 and a surrounding plate 12. The surrounding plate 12 is connected to the outer periphery of the bottom plate 11. The surrounding plate 12 and the bottom plate 11 together define a receiving cavity for receiving the packaging bag 1. The bottom plate 11 is provided with a bag-removing opening 111 that extends through the thickness direction.

[0044] In some embodiments, the surrounding plate 12 is connected to the outer periphery of the base plate 11, and the surrounding plate 12 and the base plate 11 together form a closed or semi-closed space, that is, a receiving cavity for accommodating the packaging bag 1. The receiving cavity provides a place for storing the packaging bag 1, so that the packaging bag 1 can be neatly stacked in the bag box 10. The base plate 11 is provided with a bag-removing opening 111 that extends through in the thickness direction. The function of the bag-removing opening 111 is to allow the bag-removing clamp to pass through, so that the packaging bag 1 can be removed from the inside of the bag box 10.

[0045] Understandably, the sidewalls of the enclosure 12 are used to laterally restrain the packaging bag 1, preventing it from scattering or tipping over inside the bag box 10. The bottom plate 11 provides support and bears the weight of the packaging bag 1. When it is necessary to remove the bag, the bag-removing clamp moves to the bag-removing opening 111 of the bag box 10 under the drive of the worktable. Since the bag-removing opening 111 is through the thickness direction of the bottom plate 11, the bag-removing clamp can extend into the bag box 10 through the bag-removing opening 111, contact the bottom packaging bag 1, and remove the packaging bag 1 from the bag box 10 by means of suction, gripping, etc.

[0046] It is worth mentioning that electrostatic adsorption may occur between the packaging bag 1 to be removed and other packaging bags 1, resulting in the removal of multiple packaging bags 1 at one time. With the above-described configuration, when the first suction device engages with and removes the packaging bag 1, the packaging bag 1 to be removed is taken out through the bag-removing opening 111. The portion of the bottom plate 11 located at the outer periphery of the bag-removing opening 111 can obstruct the removal of the packaging bag 1, causing the outer periphery of the packaging bag 1 to be removed to bend and deform, thereby increasing the gap between the packaging bag 1 to be removed and other packaging bags 1. This eliminates the electrostatic adsorption phenomenon between the packaging bags 1, achieving the effect of removing only one packaging bag 1 at a time.

[0047] According to some embodiments of the present invention, the enclosure 12 and / or the bottom plate 11 are made of transparent material. In some embodiments, the enclosure 12 is made of transparent material, which allows the operator to easily view the quantity and filling of the packaging bags 1 inside the bagging box 10. In other embodiments, the bottom plate 11 is made of transparent material, which also allows the operator to easily view the quantity and filling of the packaging bags 1 inside the bagging box 10. In still other embodiments, both the enclosure 12 and the bottom plate 11 are made of transparent material, which also allows the operator to easily view the quantity and filling of the packaging bags 1 inside the bagging box 10.

[0048] According to some embodiments of the present invention, the enclosure 12 is made of transparent material, and a sensor 13 is provided on the side of the enclosure 12 near the bottom plate 11. The sensor 13 is adapted to sense the height of the packaging bag 1 inside the receiving cavity, and the sensor 13 is adapted to alarm when the height of the packaging bag 1 is lower than a preset value.

[0049] In some embodiments, the sensor 13 has the function of sensing the height of the packaging bag 1 inside the receiving cavity. The sensor 13 can obtain the height information of the packaging bag 1 inside the bag box 10 in real time through a specific sensing principle (such as infrared sensing, ultrasonic sensing, etc., which are not limited here).

[0050] Understandably, by using sensor 13 to monitor the height of packaging bag 1 in real time and to sound an alarm when the remaining amount is insufficient, operators can know immediately that packaging bag 1 is about to run out and replenish it in time, thus avoiding interruption of the bagging work due to the running out of packaging bag 1 and ensuring the continuity and efficiency of production.

[0051] According to some embodiments of the present invention, the bagging device further includes a clamping plate 40, which is movably connected to the worktable. The clamping plate 40 is adapted to clamp the packaging bag 1 in the thickness direction after the test paper is placed into the packaging bag 1, and the clamping plate 40 moves in the length direction to transport the packaging bag 1 to the collection box.

[0052] The clamping plate 40 consists of two opposing clamping components. These two clamping components can be opened and closed by a drive device such as a cylinder or motor. When it is necessary to clamp the packaging bag 1, the drive device brings the two clamping components closer to each other and applies a certain pressure to the packaging bag 1, thereby achieving clamping.

[0053] In some embodiments, the clamping plate 40 is connected to the worktable via mechanical structures such as guide rails, sliders, and motor drives, so that the clamping plate 40 has flexible movement capabilities, which is not limited here. The clamping plate 40 is disposed on one side of the worktable in the width direction. After the test paper is placed into the packaging bag 1, the clamping plate 40 begins to function to clamp the packaging bag 1 in the thickness direction. Then, the clamping plate 40 moves in the length direction to transport the packaging bag 1 to the collection box, thereby completing the transfer of the packaging bag 1.

[0054] According to some embodiments of the present invention, the bagging device further includes a sealing machine 50, which is disposed between the bag-taking clamp and the collection box. The sealing machine 50 is adapted to seal the packaging bag 1 before the clamp 40 transports the packaging bag 1 to the collection box. The sealing machine 50 includes a lower pressure plate and an upper pressure plate. The lower pressure plate is connected to the worktable, and the upper pressure plate is movably connected to the worktable. The upper pressure plate is adapted to move toward or away from the lower pressure plate in the height direction. When the upper pressure plate and the lower pressure plate cooperate to press the packaging bag 1, the upper pressure plate and / or the lower pressure plate are heated to seal the packaging bag 1.

[0055] In some embodiments, the sealing machine 50 is positioned between the bag-retrieving clamp and the collection box. The main function of the sealing machine 50 is to seal the packaging bag 1 before the clamp 40 transports it to the collection box. The purpose of sealing is to seal the opening of the packaging bag 1 to prevent the trace explosive sampling test strip inside from being contaminated by the external environment, getting damp, or being accidentally touched. It also facilitates the storage and transportation of the packaging bag 1.

[0056] The moving connection structure between the upper pressure plate and the worktable is based on the principle of mechanical transmission. For example, a motor drives a lead screw and nut mechanism. When the motor rotates, the lead screw rotates, and the nut moves linearly along the lead screw. The nut is connected to the upper pressure plate, thereby realizing the movement of the upper pressure plate in the height direction; or a cylinder can be used for drive. The piston rod of the cylinder extends and retracts, driving the upper pressure plate to move up and down. There are no restrictions here.

[0057] The upper and / or lower pressure plates are equipped with heating elements. When energized, these elements generate heat, which is transferred to the upper and / or lower pressure plates via thermal conduction, raising their surface temperature. When the upper and lower pressure plates press the packaging bag 1 tightly, heat is transferred from the upper and / or lower pressure plates to the sealing area of ​​the packaging bag 1, causing the plastic material in the sealing area to melt. Under the pressure of the upper and lower pressure plates, the molten plastic material is squeezed and fused together, forming a uniform sealing layer. As heat dissipates, the sealing layer cools and solidifies, completing the sealing process.

[0058] According to some embodiments of the present invention, the bagging device further includes a laser coding machine 60, which is disposed between the sealing machine 50 and the collection box. The laser coding machine 60 is provided with a laser head facing the top of the packaging bag 1, and the laser coding machine 60 works to perform laser coding on the packaging bag 1 through the laser head.

[0059] In some embodiments, during the automated process of the bagging device, after the packaging bag 1 exits the sealing machine 50, it is transported to the coding station of the laser coding machine 60. At this time, the laser coding machine 60 starts, and the laser head codes the top of the packaging bag 1 according to a preset program. After coding is completed, the packaging bag 1 continues to be transported to the collection box.

[0060] It is worth mentioning that the laser marking machine 60 uses a high-energy-density laser emitted from a laser head to locally irradiate the surface of the packaging bag 1, causing physical or chemical changes in the material on the surface of the packaging bag 1, thereby forming the desired mark.

[0061] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0062] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
