Description

Technical Field

[0001] This invention relates to the technical field of explosive strip detection devices, and particularly to an emulsion explosive strip detection device and detection method. Background Technology

[0002] Emulsion explosives are water-in-oil emulsion explosives that utilize emulsifiers to uniformly disperse microdroplets of an oxidizing agent salt aqueous solution within a continuous oil-phase medium containing porous materials such as dispersed air bubbles or hollow glass microspheres. The density parameter of emulsion explosives directly affects their detonation reliability, detonation performance, and safety during storage and transportation. Therefore, after the production of emulsion explosives, their density usually needs to be tested. Existing testing methods typically require placing the emulsion explosive in a liquid medium and calculating its volume based on the change in liquid level, combined with its own mass, to obtain the density parameter. However, in this testing process, the explosive charge is directly immersed in the liquid, and after testing, liquid medium residue adheres to the outer wall of the corresponding emulsion explosive, which must be removed by subsequent drying, making the testing process cumbersome. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the background art by proposing an explosive strip detection device and method that is efficient and fast, avoids direct contact between the liquid medium and the emulsion explosive during the detection process, and eliminates the need to dry the emulsion explosive after detection.

Two clamping plates are movably connected to the right side of the movable plate, and a placement groove is provided on the upper side of the clamping plates. Two connecting shafts are symmetrically and movably connected to the right side of the conveyor frame. A membrane is sleeved in the middle of the two connecting shafts. A frame is fixedly installed on the conveyor frame directly below the membrane. The frame is filled with detection liquid, and the liquid level of the detection liquid is at the same height as the top surface of the frame.

[0008] Optionally, the film has a square structure with multiple magnetic sheets inside, and the top surface of the magnetic sheets is on the same horizontal plane as the top surface of the film.

[0009] Optionally, the adjusting mechanism includes a movable plate movably connected to the conveyor frame, a support frame fixedly installed on the right side of the conveyor frame, the movable plate slidingly engaging with a sliding groove opened on the support frame, a piston rod fixedly installed on the top surface of the movable plate, and the adjusting mechanism also includes a piston tube fixedly connected to the conveyor frame, the upper end of the piston rod being inserted into the piston tube and maintaining a sliding engagement with it.

[0010] Optionally, a pressing plate is fixedly installed at the lower end of the movable plate, and a magnetic strip is fixedly installed on the outer wall of the pressing plate, and the magnetic strip and the magnetic sheet are magnetically attracted to each other.

[0011] Optionally, it also includes a capsule located on the left side of the connecting plate. The capsule is connected to the piston tube through a connecting pipe.

Detailed Implementation

[0016] The technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] like Figures 1 to 9As shown, the present invention proposes an emulsion explosive strip testing device, including a conveyor frame 100; a conveying mechanism, located on the left side of the conveyor frame 100, for conveying the explosive strip to the testing station. The conveying mechanism includes a movable plate 200 movably connected to the conveyor frame 100, and two clamping plates 300 movably connected to the right side of the movable plate 200. A placement groove 301 is provided on the upper side of the clamping plate 300. Specifically, in this application, the explosive strip to be tested is placed in the placement groove 301 on the clamping plate 300, and the size of the placement groove 301 is adapted to the actual size of the explosive strip to be tested. Furthermore, the conveying mechanism can adjust the position of the explosive strip in the placement groove 301 and can convey the explosive strip to the testing station.

[0022] Furthermore, in this application, a film 420 is provided at the lower position of the testing station. Correspondingly, the conveying mechanism can convey the drug strip to the testing station. The drug strip will fall downward under the action of mass and be located on the upper position of the film 420. Two connecting shafts 410 are symmetrically and movably connected on the right side of the conveying frame 100. The film 420 is sleeved in the middle of the two connecting shafts 410. In the actual testing process, an adjustment mechanism is also provided at the upper position of the film 420. The adjustment mechanism is used to squeeze the drug strip located on the upper position of the film 420 into the frame 500.

[0023] Among them, a frame 500 is fixedly installed on the conveyor frame 100 directly below the film 420. The frame 500 is filled with detection liquid, and the liquid level of the detection liquid is at the same height as the top surface of the frame 500.

[0024] In one implementation, two symmetrical grooves 201 are formed on the right outer wall of the movable plate 200. The movable plate 200 is fixedly connected to the output end of an external hydraulic cylinder via a connecting rod. A guide rod 320 is fixedly installed on the left outer wall of the clamping plate 300. The left end of the guide rod 320 is inserted into the groove 201 and slides with it. The two clamping plates 300 are elastically connected at their middle parts by a spring 310. The fixed connection between the corresponding hydraulic cylinder and the movable plate 200 via the connecting rod, and the sliding engagement between the movable plate 200 and the guide groove 101 formed on the top surface of the conveying frame 100, ensure the stability of the conveying mechanism during use.

[0025] Furthermore, a connecting plate 210 is fixedly installed on the outer right side of the movable plate 200. The connecting plate 210 is slidably engaged with the limiting groove 102 opened on the inner wall of the bottom surface of the guide groove 101. When the movable plate 200 slides in the guide groove 101, the corresponding connecting plate 210, which is fixedly connected to the movable plate 200, will also slide synchronously in the limiting groove 102, thereby ensuring the stability of the movable plate 200 when adjusting its position.

[0026] Regarding how the automatic unloading of the drug strips is achieved in the placement slot 301, in this application, the guide rod 320, which is fixedly connected to the clamping plate 300, slides in the slide groove 201. When the two clamping plates 300 separate from each other, the drug strips that were originally in the placement slot 301 will fall down from the gap mentioned above and land on the upper surface of the coating 420.

[0027] Furthermore, in this application, an adjusting plate 130 is fixedly installed on the right side of the top surface of the guide groove 101. A first inclined surface 131 is symmetrically opened on the left outer wall of the adjusting plate 130, and a second inclined surface 302 is opened on the left side of the bottom surface of the clamping plate 300. The first inclined surface 131 and the second inclined surface 302 are slidably engaged. When the moving plate 200 moves along the guide groove 101 to the side of the testing station, the second inclined surface 302 opened on the lower outer wall of the clamping plate 300 will slide relative to the first inclined surface 131. Correspondingly, the two clamping plates 300 will move away from each other, and the corresponding guide rod 320 will slide to both sides in the slide groove 201. At this time, the two clamping plates 300 will move away from each other, and the medicine strip in the placement groove 301 will fall from the middle of the two clamping plates 300 and be placed on the surface of the film 420 of the testing station, waiting for subsequent medicine strip testing.

[0028] When the pill is on the upper surface of the film 420, the height of the pill in the vertical direction is adjusted by the set adjustment mechanism. Specifically, the adjustment mechanism includes a movable plate 600 movably connected to the conveyor frame 100, a support frame 110 fixedly installed on the right side of the conveyor frame 100, the movable plate 600 slidingly engaging with the sliding groove 111 opened on the support frame 110, and a piston rod 610 fixedly installed on the top surface of the movable plate 600. The adjustment mechanism also includes a piston tube 620 fixedly connected to the conveyor frame 100, and the upper end of the piston rod 610 is inserted into the piston tube 620 and slides therewith. In conjunction with this, a compression plate 630 is fixedly installed at the lower end of the movable plate 600. In actual use, by injecting gas into the piston tube 620, the piston rod 610, which is movably connected to the piston tube 620, will move vertically downward. Combined with the fixed connection between the piston rod 610 and the movable plate 600, and the compression plate 630 fixedly connected to the lower end of the movable plate 600, when the piston rod 610 moves downward, the corresponding compression plate 630 will move downward and compress the medicine strip on the film 420, causing the medicine strip and the film 420 to move into the interior of the frame 500.

[0029] In one embodiment, the detection device in this application further includes a capsule 220 disposed on the left side of the connecting plate 210. The capsule 220 is connected to the piston tube 620 via a connecting pipe 221. Specifically, the method of injecting gas into the piston tube 620 is as follows: First, during the drug delivery stage, when the corresponding moving plate 200 moves towards the detection station, the capsule 220 will be stretched. Combined with the connection between the capsule 220 and the piston tube 620 via the connecting pipe 221, when the capsule 220 is stretched, the gas in the corresponding piston tube 620 will be extracted. At this time, the piston rod 610, which is movably connected in the piston tube 620, will move upward, thereby driving the extrusion plate 630 to move upward. At this time, the clamping plate 300 will be in the position of the detection station, and the extrusion plate 630 will move upward to avoid it. Subsequently, during the height adjustment phase of the pill, the delivery mechanism will reset, and the corresponding moving plate 200 will drive the connecting plate 210 to reset. The corresponding capsule 220 will change from a stretched state to a compressed state. At this time, the gas inside the capsule 220 will be squeezed into the piston tube 620. The piston rod 610, which is movably connected inside the piston tube 620, will drive the extrusion plate 630 to move downward. It should be noted that when the pill is being adjusted in height, it is positioned above the film 420. When the extrusion plate 630 contacts the upper outer wall of the pill and continues to move downward, the bottom surface of the pill always maintains stable contact with the film 420.

[0030] Regarding the testing process, in this application, when the extrusion plate 630 moves the strip downwards synchronously, the coating 420 on the bottom surface of the strip also moves downwards synchronously and deforms. Specifically, in order to ensure that the coating 420 completely wraps the strip, thereby preventing the strip from directly contacting the test liquid inside the frame 500 during testing and avoiding moisture, thus eliminating the need for subsequent drying, and to ensure the adhesion between the coating 420 and the outer wall of the strip, in this application, the coating 420... The outer wall of the extrusion plate 630 has a route that matches the edge of the strip and multiple magnetic pieces 421 are provided. Similarly, magnetic strips 631 are also provided on the outer walls of the extrusion plate 630. When the extrusion plate 630 moves the strip downwards, the corresponding magnetic pieces 421 will magnetically attract the magnetic strips 631. Before the magnetic pieces 421 come into contact with the magnetic strips 631, the film 420 does not come into contact with the detection liquid inside the frame 500. Only after the film 420 completely wraps the edge of the strip will it continue to move downwards into the frame 500. As mentioned above, during the downward movement of the strip, the magnetic sheet 421 and the magnetic strip 631 are magnetically attracted to each other. Before the strip is immersed in the test liquid, the film 420 completely wraps the bottom surface and the outer walls of the strip, protecting it. Subsequently, as the extrusion plate 630 continues to move the strip downward, it will gradually be immersed in the test liquid contained in the frame 500.

[0031] It should be noted that in this application, the interior of the frame 500 is filled with detection liquid, and in the vertical direction, the liquid level of the detection liquid is at the same level as the top surface of the frame 500. When the strip wrapped by the film 420 is immersed in the detection liquid, the detection liquid will overflow from the frame 500. It is worth noting that when the top surface of the strip (or the bottom surface of the extrusion plate 630) is at the same height as the top surface of the frame 500, the extrusion plate 630 stops moving downward. This means that the strip is immersed in the detection liquid (except for its top surface, but at this time the top surface of the strip is at the same level as the top surface of the frame 500). Correspondingly, the volume parameter of the detection liquid obtained from the frame 500 in the above process is the volume parameter V1 of the strip. As one implementation method, during the process of the aforementioned strip moving downwards and immersing itself in the frame 500 until it stops, the corresponding detection liquid will overflow from the frame 500. However, the volume of the overflowing detection liquid actually includes the volume of the strip itself, as well as the volume of the coating that is wrapped around the bottom surface and the surrounding outer walls of the strip, including the film adsorbed at the corners of the strip. To improve accuracy, an external parameter V2 can be introduced. V2 is used to represent the volume of detection liquid overflow caused by the coating being immersed in the detection liquid inside the frame 500 (the principle of introducing V2 is to refer to the area of ​​the surrounding outer walls of the strip and the area of ​​its bottom surface, combined with the thickness of the coating 420 itself, and multiply the two to obtain the volume parameter V2 of the coating 420 wrapped around the outer wall of the strip mentioned above). V1 is subtracted from V2 to obtain the volume V, and the volume V can more accurately represent the volume parameter of the strip.

[0032] In this application, a mass sensor is installed on the bottom surface of the placement groove 301. When the medicine strip is conveyed, the mass value M of the medicine strip can be obtained. Based on the known mass M and the corresponding volume V, the density parameter of the medicine strip can be calculated.

[0033] Unloading scheme: Specifically, after a strip is tested once, it is understood that the corresponding strip is completely immersed in the test liquid. After the height of the corresponding liquid level rise is determined, the volume of the corresponding strip can be determined. In the next strip test, the strip that was originally on the film 420 needs to be unloaded. The connecting shaft 410 is fixedly connected to the output shaft of the servo motor 400 fixedly installed on the outer wall of one side of the conveyor frame 100. A coil spring 431 is sleeved on the right end of the connecting shaft 410. One end of the coil spring 431 is fixedly connected to the connecting shaft 410, and the other end of the coil spring 431 is fixedly connected to the housing 430 fixedly installed on the outer wall of the conveyor frame 100. A crossbeam 120 is fixedly installed on the lower side of the limiting groove 102. A delay trigger switch 121 is fixedly installed on the right end of the crossbeam 120. When the outer wall of the connecting plate 210 contacts the delay trigger switch 121, the corresponding servo motor 400 starts after a delay, driving the film 420 to rewind.

[0034] Specifically, during the previous pill delivery process, the outer wall of the connecting plate 210 contacts the delayed trigger switch 121 located at the end of the crossbar 120. At this time, the two clamping plates 300 are at their furthest distance, and the pill falls onto the upper surface of the film 420. After delivery, the moving plate 200 slides to the left and resets within the guide groove 101, and the clamping plates 300 reset under the action of the spring 310. Subsequently, after the moving plate 200 resets, the capsule 220 is in a compressed state, and the compression plate 630 moves to its lowest position. After detection (meaning the compression plate 630 moves downwards to its bottom), the capsule 220 is compressed. When the surface of the tablet and the top surface of the frame 500 are at the same height, the test is considered complete. The corresponding moving plate 200 will then transport the next tablet to be tested, and the corresponding pressing plate 630 will move upward. When the moving plate 200 has not moved to the leftmost position, that is, when the corresponding first inclined surface 131 has not slid relative to the second inclined surface 302, the corresponding delay trigger switch 121 will turn on the servo motor 400 and be in running state. At this time, it can drive the connecting shaft 410 to rotate. The corresponding film 420 wrapped between the middle of the two connecting shafts 410 will move along the winding direction. In this way, the tested tablet can be unloaded in the conveying direction of the film 420.

[0035] It should be noted that after one unloading is completed, multiple sets of square magnetic sheets 421 are provided on the corresponding film 420. Another set of square magnetic sheets 421 will be placed directly below the detection station again, so that the medicine strips subsequently delivered by the clamping plate 300 can be stably placed in the middle of multiple magnetic sheets 421. The rotation direction of the film 420 for the next unloading is the opposite of the previous rotation direction. The spring 431 set on the outer wall of the connecting shaft 410, combined with the elasticity of the film 420, ensures that after each adjustment of the position of the film 420, the square magnetic sheets 421 will be placed directly below the detection station again to better receive the subsequent medicine strips. During this process, the detection liquid is injected into the frame 500 by an external pump, and the injection is stopped when the liquid level of the detection liquid is at the same height as the top surface of the frame 500.

[0036] A detection method for an emulsion explosive strip detection device includes the following steps: Step 1: Place the strip to be tested on the placement slot 301, adjust the position of the clamping plate 300 relative to the conveyor frame 100 with the help of the external drive mechanism, and place the strip on the testing station, which is also directly above the frame 500. Step 2: Using the adjustment mechanism in the vertical direction, together with the extrusion plate 630, the strip is extruded into the frame 500 until the detection liquid surface is at the same level as the bottom surface of the extrusion plate 630, and the volume of the detection liquid overflowing from the frame 500 is obtained. Step 3: The volume of the test liquid that overflows from the frame 500 is the volume of the strip. The density of the strip can be calculated by combining the mass of the strip. Step 4: When the conveying mechanism moves to the right, after the connecting plate 210 contacts the time-delay trigger switch 121, the subsequent moving plate 200 moves to the left to reset the corresponding extrusion plate 630, and at this time the film covering 420 unloads the medicine strip.

[0037] The above specific embodiments are merely several optional embodiments of the present invention.

The emulsion explosive strip detection device according to claim 5, characterized in that, The adjustment mechanism also includes a support frame (110) fixedly installed on the right side of the conveyor frame (100), the movable plate (600) is slidably engaged with the sliding groove (111) opened on the support frame (110), and a piston rod (610) is fixedly installed on the top surface of the movable plate (600). The adjustment mechanism also includes a piston tube (620) that is fixedly connected to the conveyor frame (100), and the upper end of the piston rod (610) is inserted into the piston tube (620) and slidably engaged with it.

7. The emulsion explosive strip detection device according to claim 6, characterized in that, It also includes a capsule (220) located on the left side of the connecting plate (210). The capsule (220) is connected to the piston tube (620) through the connecting pipe (221). A crossbeam (120) is fixedly installed on the lower side of the limiting groove (102). A time-delayed trigger switch (121) is fixedly installed on the right end of the crossbeam (120). When the outer wall of the connecting plate (210) contacts the time-delayed trigger switch (121), the corresponding servo motor (400) starts after a delay, driving the film (420) to wind up.

8. A method for detecting explosive charges, applied to the emulsion explosive charge detection device as described in claim 7, characterized in that, Includes the following steps: Step 1: Place the strip to be tested in the placement slot (301), adjust the position of the clamp (300) relative to the conveyor frame (100) with the help of the external drive mechanism, and place the strip on the testing station, directly above the corresponding frame (500); Step 2: Use the adjustment mechanism to drive the squeezing plate (630) in the vertical direction to squeeze the strip into the frame (500) until the detection liquid surface and the bottom surface of the squeezing plate (630) are on the same horizontal plane, and obtain the volume of the detection liquid overflowing from the frame (500); Step 3: The volume of the detection liquid overflowing from the frame (500) includes the volume of the strip itself, as well as the volume of the coating that is wrapped around the bottom surface of the strip and its surrounding outer walls, and adsorbed together at the corners of the strip. The density of the strip is calculated by combining the mass of the strip. Step 4: When the conveying mechanism moves to the right, the connecting plate (210) will contact the delayed trigger switch (121). When the moving plate (200) moves to the rightmost position, the conveying of the medicine strip is completed. When the moving plate (200) moves to the left and resets, the extrusion plate (630) is at the bottommost position. When the moving plate (200) moves to the right again, the corresponding extrusion plate (630) moves up. At this time, the film (420) unloads the medicine strip.
