[0002] In the field of security inspection, the detection of trace explosives (contraband) is a crucial task, concerning multiple key aspects such as public safety, counter-terrorism, and riot control. Trace explosive sampling test strips, as a commonly used detection tool, are widely used in densely populated places such as airports, train stations, and large event venues, as well as key areas where there may be explosive threats, due to their advantages of ease of operation and high detection sensitivity.

[0003] In automated sampling systems, the suction force of the suction arm is usually used to pick up the test strips from the paper tray. However, due to electrostatic adsorption, the suction arm often picks up multiple test strips at once, which affects the sampling results and efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic paper dispenser for contraband sampling test strips, thereby improving the aforementioned problems. To achieve this objective, the technical solution adopted by this invention is as follows:

[0005] This application provides an automatic paper dispenser for contraband sampling test strips, comprising: a box body, wherein the box body is provided with a receiving cavity suitable for accommodating test strips, and the top of the box body is provided with an open opening communicating with the receiving cavity; a pressure plate, the pressure plate being connected to the box body, the pressure plate being provided with a protrusion, and the projection of the protrusion in the height direction of the box body being located within the receiving cavity.

[0006] According to some embodiments of the present invention, the side wall of the box body is provided with a sliding groove extending along the height direction of the box body. The sliding groove is adapted to communicate the receiving cavity with the outside. The pressure plate is sleeved on the outer periphery of the box body, and a portion of the protrusion is movably disposed within the sliding groove.

[0007] According to some embodiments of the present invention, the box body is provided with the sliding groove on both sides in its width direction, and the protrusion is constructed as a plurality of parts corresponding one-to-one with the sliding groove.

[0008] According to some embodiments of the present invention, the box body is provided with a plurality of partitions, which are adapted to divide the receiving cavity into a plurality of receiving cavities spaced apart from each other along the length direction of the box body, and one receiving cavity corresponds to two slides.

[0009] According to some embodiments of the present invention, the box body includes a bottom plate, and the bottom plate is provided with side plates on both sides in its width direction. The bottom plate and the side plates together define the receiving cavity. The side plates are provided with the sliding groove, and the bottom plate is provided with a plurality of partitions spaced apart from each other in its length direction. The receiving cavity is defined between two adjacent partitions.

[0010] According to some embodiments of the present invention, the box body further includes a pad, the pad being configured as a plurality of corresponding to the plurality of receiving cavities, and the plurality of pads being respectively connected to the bottom plate, the cross section of the pad corresponding to the test paper.

[0011] According to some embodiments of the present invention, the top surface of the box body is provided with a communication port that communicates with the slide groove, the communication port is connected to the open opening, and the protrusion is detachably connected to the box body through the communication port.

[0012] According to some embodiments of the present invention, the size of the connecting opening gradually increases in the length direction of the box body in the direction away from the slide groove.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] 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.

[0026] like Figures 1-3As shown, this embodiment provides an automatic paper dispenser for contraband sampling test strips, including: a box body 10 and a pressure plate 20. The box body 10 is provided with a receiving cavity suitable for accommodating test strips. The top of the box body 10 is provided with an open opening communicating with the receiving cavity. The pressure plate 20 is connected to the box body 10 and is provided with a protrusion. The projection of the protrusion in the height direction of the box body 10 is located in the receiving cavity.

[0027] In some embodiments, the box body 10 has a cavity inside specifically for accommodating trace explosive sampling test strips, and the top of the box body 10 has an opening communicating with the cavity so that the test strips can be inserted or removed through the opening. A pressure plate 20 is connected to the box body 10, and a protrusion is provided on the pressure plate 20. The projection of the protrusion in the height direction of the box body 10 is located inside the cavity.

[0028] It is understood that the paper tray of this application is adapted to cooperate with the paper suction arm, which moves toward the test paper in the height direction and contacts the test paper. Then the paper suction arm generates suction to hold the test paper tightly. Immediately afterwards, the paper suction arm moves away from the paper tray body 10 in the height direction to remove the test paper.

[0029] When the suction arm approaches the test strip for suction, multiple test strips may be attracted simultaneously due to static electricity or other factors. At this time, the protrusion of the pressure plate 20 acts as a blocking member. The protrusion can contact the edge of the test strip when the test strip is removed, thereby deforming the edge of the test strip. Since the attracted test strip is tightly fitted with the suction arm, the attracted test strip will not fall off. However, the edge of the attracted test strip will be deformed, thereby creating a gap between the attracted test strip and the excess test strip, so as to break the electrostatic adsorption state between the test strips and separate the excess test strip from the attracted test strip.

[0030] According to the present invention, the automatic paper dispenser for sampling test strips of prohibited items has a protrusion on the pressure plate 20, and the projection of the protrusion in the height direction of the box body 10 is located in the receiving cavity. This protrusion can block the removal of the test strips. That is, when the test strips are removed, the edge of the sampled test strip is deformed, thereby creating a gap between the sampled test strip and the excess test strip, which breaks the electrostatic adsorption state between the test strips and separates the excess test strip from the sampled test strip. This effectively avoids the problem of the suction arm picking up multiple test strips at one time and achieves the goal of picking up only one test strip at a time.

[0031] According to some embodiments of the present invention, the side wall of the box body 10 is provided with a sliding groove 11 extending along the height direction of the box body 10. The sliding groove 11 is suitable for communicating the receiving cavity with the outside. The pressure plate 20 is sleeved on the outer periphery of the box body 10, and the protruding part is movably disposed in the sliding groove 11.

[0032] In some embodiments, the side wall of the box body 10 is provided with a slide groove 11, which extends along the height direction of the box body 10. The pressure plate 20 is sleeved on the outer periphery of the box body 10, and a portion of the protrusion on the pressure plate 20 is movably disposed in the slide groove 11, that is, the protrusion can move up and down along the height direction of the box body 10 in the slide groove 11, thereby driving the pressure plate 20 to move as a whole.

[0033] It is worth mentioning that the inner peripheral wall of the slide groove 11 can restrict the outer peripheral wall of the protrusion, allowing the protrusion to move stably along the extending direction of the slide groove 11, so that the pressure plate 20 can move stably along the height direction of the box body 10. Of course, since the pressure plate 20 is fitted onto the outer periphery of the box body 10, the outer peripheral wall of the box body 10 can also restrict the inner peripheral wall of the pressure plate 20, meaning the box body 10 can act as a guide rail for the pressure plate 20, allowing the box body 10 to move stably along its height direction.

[0034] Understandably, as the number of test strips decreases, the pressure plate 20 moves downward along the height direction of the box 10 under the action of gravity, so that the protrusion moves downward accordingly. This allows the protrusion to always be in contact with the remaining test strips and maintain the pressing effect on the remaining test strips, thereby maintaining the flatness and cleanliness of the test strips and reducing the risk of contamination or damage caused by loose or misaligned test strips.

[0035] It should be noted that in the automated sampling system, the paper tray of this application can work in conjunction with automated equipment such as the paper suction arm to achieve an efficient and accurate test strip aspiration and detection process. Specifically, the automatic adjustment function of the pressure plate 20 ensures that the test strip is in the correct position and state each time it is aspirated.

[0036] According to some embodiments of the present invention, the box body 10 is provided with grooves 11 on both sides in the width direction, and the protrusions are constructed to correspond one-to-one with the grooves 11.

[0037] In some embodiments, the box body 10 has grooves 11 distributed on both sides in the width direction, and the protrusions on the pressure plate 20 are configured to correspond one-to-one with the grooves 11, that is, each groove 11 has a corresponding protrusion, and the protrusions can move in their respective grooves 11, together driving the pressure plate 20 to move up and down.

[0038] Therefore, the pressure plate 20 experiences uniform force from both sides during movement, maintaining good balance. This helps the pressure plate 20 move more accurately to follow changes in the amount of test paper used, consistently maintaining stable pressure on the test paper and reducing problems such as uneven pressure or difficulty in absorption caused by the pressure plate 20 shaking or tilting. Furthermore, the multiple protrusions work collaboratively within their respective grooves 11, jointly driving the pressure plate 20 up and down, ensuring smooth and accurate movement and improving the overall efficiency of the paper tray.

[0039] According to some embodiments of the present invention, a plurality of partitions 14 are provided inside the box body 10. The plurality of partitions 14 are adapted to divide the receiving cavity into a plurality of receiving cavities spaced apart from each other along the length direction of the box body 10, and one receiving cavity corresponds to two slides 11.

[0040] Understandably, multiple partitions 14 divide the receiving cavity into multiple receiving chambers, each of which can hold test strips. Here, the test strips placed in each receiving chamber can be of different or the same type, thereby improving the compatibility and applicability of the placement box. In other words, the partitions 14 divide the receiving cavity into multiple receiving chambers, each of which can be used to store different types or batches of test strips, facilitating management and use.

[0041] In some embodiments, the test strips in each receiving cavity are of the same type and in the same quantity. The suction arm is equipped with the same number of pipettes as the receiving cavities. The multiple pipettes correspond one-to-one with the multiple receiving cavities, thereby enabling the simultaneous suction of multiple test strips during operation.

[0042] Of course, one receiving cavity corresponds to two sliding grooves 11, and thus, one receiving cavity corresponds to two protrusions. That is, the test strip in each receiving cavity can be pressed tightly by the two protrusions, making the placement of the test strip more stable. At the same time, when the test strip in each receiving cavity is removed, both ends of the test strip can be acted upon by the protrusions, so that both ends of the absorbed test strip can be deformed, thereby allowing the absorbed test strip to be better separated from the excess test strip, achieving a more stable effect of absorbing one test strip at a time.

[0043] According to some embodiments of the present invention, the box body 10 includes a bottom plate 12, and side plates 13 are provided on both sides of the bottom plate 12 in the width direction. The bottom plate 12 and the side plates 13 together define a receiving cavity. The side plates 13 are provided with sliding grooves 11, and the bottom plate 12 is provided with a plurality of partitions 14 spaced apart from each other in the length direction. A receiving cavity is defined between two adjacent partitions 14.

[0044] In some embodiments, the bottom plate 12 serves as the bottom support of the box body 10, and the side plates 13 on both sides together with the bottom plate 12 form the basic framework of the receiving cavity, providing space for the storage of test strips. Multiple partitions 14 are provided on the bottom plate 12, which are spaced apart from each other. The partitions 14 divide the receiving cavity into multiple independent receiving cavities. Each receiving cavity can be used to store a specific type or batch of test strips, realizing the classified storage of test strips, which is convenient for management and use. The sliding grooves 11 provided on the side plates 13 provide guidance for the movement of the pressure plate 20. The pressure plate 20 can move vertically along the sliding grooves 11 to adapt to the change in the number of test strips in different receiving cavities, and always maintain stable pressure on the test strips.

[0045] According to some embodiments of the present invention, the box body 10 further includes a pad 15, which is configured to correspond one-to-one with a plurality of receiving cavities, and the plurality of pads 15 are respectively connected to the bottom plate 12, and the cross section of the pad 15 corresponds to the test paper.

[0046] In some embodiments, the cross section of the pad 15 corresponds to the test paper, that is, the pad 15 can precisely fit the shape of the test paper, providing uniform and stable support for the test paper and preventing the test paper from becoming skewed or deformed in the receiving cavity.

[0047] The pad 15 is connected to the base plate 12 and fixed in the receiving cavity, so that the test strip is relatively fixed after being placed on the pad 15, which makes it easy for the pressure plate 20 to accurately press the test strip, and also makes it easy for the suction arm and other equipment to accurately pick up the test strip.

[0048] It is worth mentioning that, since the pad 15 corresponds one-to-one with the receiving cavity, the pad 15 in different receiving cavities can be designed according to the shape and size of different types or batches of test strips stored, so as to achieve better adaptability.

[0049] According to some embodiments of the present invention, the top surface of the box body 10 is provided with a communication port 17 that communicates with the slide groove 11. The communication port 17 communicates with the open opening, and the protrusion is detachably connected to the box body 10 through the communication port 17.

[0050] In some embodiments, the communication port 17 provides an operating channel on the top surface of the box body 10 that directly communicates with the slide groove 11 and the open opening. When it is necessary to separate the box body 10 from the pressure plate 20, the protrusion can be slid out of the slide groove 11 through the communication port 17 to complete the separation of the box body 10 from the pressure plate 20.

[0051] Understandably, since the test strips are placed in a large stack, they are not easily bent or folded during placement, and the protrusion would affect the placement process. Therefore, with the above-mentioned design, the pressure plate 20 can be separated from the box body 10 first, then the test strips can be placed, and finally the pressure plate 20 can be fitted onto the outer periphery of the box body 10, allowing the protrusion to slide and engage with the groove 11.

[0052] According to some embodiments of this utility model, the dimension of the connecting opening 17 gradually increases in the length direction of the box body 10 in the direction away from the slide groove 11. It can be understood that the above arrangement allows the connecting opening 17 to have a guiding function, that is, when it is necessary to connect the box body 10 and the pressure plate 20, the connecting opening 17 can guide the protrusion, so that the protrusion is received in the slide groove 11, thereby facilitating the connection between the box body 10 and the pressure plate 20.

[0053] According to some embodiments of the present invention, the pressure plate 20 includes a surrounding plate 21, which is sleeved on the outer periphery of the box body 10. The inner peripheral wall of the surrounding plate 21 is provided with a stop bar 22 extending toward the box body 10, and the stop bar 22 is constructed as a protrusion.

[0054] In some embodiments, the pressure plate 20 includes a surrounding plate 21, which is sleeved on the outer periphery of the box body 10. That is, the surrounding plate 21 is a component surrounding the outside of the box body 10 and is connected to the box body 10 by sleeve. The inner peripheral wall of the surrounding plate 21 is provided with a stop bar 22 extending toward the box body 10. That is, the stop bar 22 extends from the inner side of the surrounding plate 21 toward the box body 10. The stop bar 22 is constructed as a protrusion. The stop bar 22 extends toward the receiving cavity, and at least a portion of the projection of the stop bar in the height direction is located in the receiving cavity.

[0055] According to some embodiments of this utility model, the side wall of the box body 10 is provided with a plurality of weight-reducing holes 16. It can be understood that the provision of weight-reducing holes 16 can reduce the weight of the paper box and reduce the production cost of the paper box.

[0056] Of course, the weight-reducing holes 16 also serve to dissipate heat and provide ventilation. When the inside of the box 10 generates a certain amount of heat or moisture due to the storage of test strips or other reasons, the weight-reducing holes 16 can promote air circulation, help dissipate heat and moisture, maintain a relatively stable internal environment of the box 10, and facilitate the long-term storage of test strips.

[0057] 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.

[0058] 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. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
