Description

Technical Field

[0001] The invention relates to the technical field of emulsion explosives, and in particular to a charging machine and a charging method for low-detonation-velocity emulsion explosives. Background Art

[0002] At present, since the advent of emulsion explosives in the form of a slurry explosive, it has been highly praised by people for its good water resistance, low price, safety and reliability, green environmental protection, and adjustable density and energy. With the rapid development of my country's economy, blasting engineering plays an increasingly important role in infrastructure construction, which puts forward a very urgent requirement for the theoretical research of industrial explosives. From the development of industrial explosives, emulsion explosives represent the development trend of the world today. After being introduced and developed by my country, and the design of formulas from simple to complex, the production of emulsion explosives has entered a new stage of development centered on "improving product quality and reducing costs, improving processes", and some new varieties with simple components, excellent performance, long storage period and low cost have emerged.

[0003] The patent document with patent number CN218951287U discloses an emulsion explosive, and in particular, relates to an emulsion explosive resistant to high pressure. It includes: an explosive body; and a pressure-bearing part surrounding the explosive body, the pressure-bearing part is in a long hollow shape; and a fixing member arranged between adjacent pressure-bearing parts; in addition, the upper end and the lower end of the pressure-bearing part are respectively provided with an upper cover and a lower cover, wherein the upper cover, the lower cover, the fixing member and the pressure-bearing part cooperate to form a pressure-bearing unit. By forming a pressure-bearing unit by the pressure-bearing part outside the outer ring of the explosive body, the fixing member between the pressure-bearing parts, and the upper cover and the lower cover, a good pressure-bearing effect can be achieved, and the emulsion explosive can be prevented from rejecting explosion due to excessive pressure.

[0004] However, in the actual production process, the inventors found that during the loading process of existing emulsion explosives, surface inspection of finished products is usually carried out by manual sorting or mechanical inspection to determine whether the products are qualified. However, some too small gaps make the difference in the surface of the finished products smaller, which leads to low detection efficiency, poor accuracy and reduced yield rate. In addition, the inventors found that squeezing and bumping during transportation will cause diaphragm damage to some products. Some too small gaps are not easy to detect during actual use. The leaking diaphragm reduces the sensitivity of the emulsion explosive, which is easy to cause explosion refusal, affecting the safety and effect of blasting. Summary of the invention

The reagent between the inner diaphragm and the outer diaphragm is convenient for visually detecting color changes during the production and charging process, and is convenient for visually observing whether the outer diaphragm is damaged during use, which has a warning effect.

[0033] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0034] Embodiment 1 like Figure 1-Figure 5 as well as Figure 15-16 As shown, a low detonation velocity emulsion explosive charging machine comprises: A conveying mechanism 1 for conveying a low-detonation-velocity emulsion explosive 6 during charging, a filling mechanism 2, a coating mechanism 3, an assembling mechanism 4 and a detecting mechanism 5 sequentially arranged along the conveying direction of the conveying mechanism 1, wherein the filling mechanism 2 is used to fill the emulsion explosive in the inner diaphragm 611 to form an explosive body 61, the coating mechanism 3 is used to apply a reagent that changes color when in contact with water on the outside of the explosive body 61, the assembling mechanism 4 is used to sequentially assemble a supporting portion 62 and an outer diaphragm 63 on the outside of the explosive body 61 to form a low-detonation-velocity emulsion explosive 6, and the detecting mechanism 5 is used to detect the outer diaphragm 63; The assembly mechanism 4 includes a membrane sleeve assembly 41, a connection assembly 42 and a punch assembly 43 which are arranged outside the conveying mechanism 1. The membrane sleeve assembly 41 is used to sleeve the outer membrane 63 on the outside of the support body 621 of the support part 62. The connection assembly 42 is used to cooperate with the conveying mechanism 1 to connect the explosive body 61 into the support body 621 and then connect the cover body 622 of the support part 62 to the support body 621. The punch assembly 43 is used to punch buckles 631 on both ends of the outer membrane 63. The low detonation velocity emulsion explosive 6 includes an explosive body 61, an outer diaphragm 63 sleeved on the outside of the explosive body 61, and a support portion 62 arranged between the explosive body 61 and the outer diaphragm 63. The support portion 62 is used to support the explosive body 61 and to support a swimming cavity 623 formed between the outer diaphragm 63 and the explosive body 61 for the movement of the agent.

[0035] In this embodiment, the coating mechanism 3 is provided to coat the outside of the explosive body 61 with a reagent that changes color when in contact with water, and then the outer diaphragm 63 is firstly sheathed on the support body 621 through the sheathing assembly 41, thereby preventing the reagent from leaking when the connecting assembly 42 and the punching assembly 43 sequentially assemble the support part 62 and the outer diaphragm 63 on the outside of the explosive body 61, and preventing the detection mechanism 5 from detecting the outer diaphragm 63. The inner diaphragm 611 and the outer diaphragm 63 are both detected by the intuitive color change of the reagent, and the detection efficiency is high and the accuracy is good. At the same time, the support part 62 in the low-detonation-velocity emulsion explosive 6 can support the explosive body 61 to prevent it from being easily damaged. The reagent retained between the explosive body 61 and the outer diaphragm 63 makes it easy for the user to intuitively observe whether the outer diaphragm 63 is damaged, which has a warning effect.

[0036] In detail, first, the explosive body 61 loaded by the filling mechanism 2 is conveyed to the coating mechanism 3 through the conveying mechanism 1 for coating, and the quality of the explosive body 61 can be visually checked according to the color change of the agent. Then, after the outer diaphragm 63 is sleeved on the outside of the support body 621 through the sleeve assembly 41, the explosive body 61 is connected between the support body 621 and the cover body 622 through the conveying mechanism 1 and the connecting assembly 42, so as to avoid leakage of the agent. Finally, the low-detonation-velocity emulsion explosive 6 formed by the outer diaphragm 63 being punched and sealed by the punching assembly 43 is conveyed to the detection mechanism 5 through the conveying mechanism 1 for detection. During the detection process, the agent on the inner diaphragm 611 swims to the inner wall of the outer diaphragm 63 through the swimming cavity 623, and then the quality is judged by judging whether the outer diaphragm 63 leaks the agent.

[0037] It should be noted that the agent can be anhydrous copper sulfate powder, which can change from white to blue when in contact with water, and the color change is very obvious, and can also swim in the swimming cavity 623; The coating mechanism 3 and the detection mechanism 5 are both provided with a housing 7 outside to protect the internal and external environment during production; In addition, the filling mechanism 2 itself and the installation method for filling the emulsion explosive and punching the sealing inner diaphragm 611 are both existing technologies and will not be described in detail here.

[0038] Further, if Figure 6-Figure 7 as well as Fig.16 As shown, the conveying mechanism 1 includes a hanging conveying line 11, a plurality of mounting seats 12 arranged at equal intervals on the hanging conveying line 11, a telescopic rod 13 slidably arranged on the mounting seat 12, a grabbing assembly 14 arranged at one end of the telescopic rod 13 and used for grabbing the buckles 631 on the inner diaphragm 611 and the outer diaphragm 63, and an elastic member 15 arranged on the mounting seat 12 and used for forcing the telescopic rod 13 to slide in a direction close to the grabbing assembly 14.

[0039] In this embodiment, when the grabbing assembly 14 is arranged to abut against the inner diaphragm 611 or the outer diaphragm 63 and grab the buckle 631, the telescopic rod 13 can slide to adjust the position between the grabbing assembly 14 and the buckle 631, thereby grabbing the buckle 631 at any height.

[0040] In detail, when in use, the conveying mounting seat 12 of the hanging conveyor line 11 makes the grabbing assembly 14 located directly above the buckle 631 on the inner diaphragm 611 or the outer diaphragm 63, and then the telescopic rod 13 is extended and retracted until the grabbing assembly 14 abuts against the inner diaphragm 611 or the outer diaphragm 63, and then the telescopic rod 13 slides to force the elastic member 15 to deform, so that the grabbing assembly 14 is positioned between the buckle 631, and finally, after the grabbing assembly 14 grasps the buckle 631, the telescopic rod 13 shortens to grab the explosive body 61 or the low detonation velocity emulsion explosive 6, and the elastic member 15 recovers its deformation to force the telescopic rod 13 to reset, so as to facilitate the next use.

[0041] It should be noted that the elastic member 15 is a coil spring, a leaf spring, etc. The elastic member 15 and the suspension conveyor line 11 themselves and the installation method are all existing technologies and will not be described in detail here.

[0042] Further, if Figure 7-Figure 9 As shown, the grabbing assembly 14 includes a pressing seat 141 disposed on the telescopic rod 13 and used to press the inner diaphragm 611 and the outer diaphragm 63, a positioning groove 142 formed on the pressing seat 141 and used to position the buckle 631, at least two mounting grooves 143 formed on the inner wall of the positioning groove 142, a clamping arm 144 slidably and rotatably disposed in the mounting groove 143, an elastic clamping portion 145 disposed on the clamping arm 144 and used to clamp the buckle 631, and a driving groove 146 formed in the mounting groove 143 and used to drive the clamping arm 144 to rotate during its sliding process.

[0043] In this embodiment, a pressing seat 141 is provided to press the inner diaphragm 611 and the outer diaphragm 63, and the positioning groove 142 is cooperated to further position the buckle 631 on the inner diaphragm 611 and the outer diaphragm 63, so that the clamping arm 144 can slide in the installation groove 143 and cooperate with the driving groove 146 to drive and rotate until the elastic clamping part 145 grasps the buckle 631, and the clamping arm 144 can slide out of the pressing seat 141 to prevent the pressing seat 141 from interfering with the application of the medicine and subsequent detection.

[0044] In detail, when in use, after the pressing seat 141 is pressed on the inner diaphragm 611 or the outer diaphragm 63 as the telescopic rod 13 is extended, the buckle 631 on the inner diaphragm 611 or the outer diaphragm 63 is able to slide into the positioning groove 142 for further positioning, and then the clamping arm 144 slides in the installation groove 143, and the driving groove 146 is able to drive the clamping arm 144 to rotate until the elastic clamping part 145 tightens the buckle 631 and deforms, and finally the tightened buckle 631 is able to slide out of the positioning groove 142 as the clamping arm 144 slides, thereby allowing the inner diaphragm 611 or the outer diaphragm 63 at and below the buckle 631 to be completely exposed, which is convenient for applying the medicine and subsequent surface inspection.

[0045] It should be noted that the positioning groove 142 includes a positioning section 1421 for positioning the buckle 631 and a receiving section 1422 for receiving the inner diaphragm 611 outside the buckle 631 and the outer diaphragm 63, thereby facilitating the positioning section 1421 to position the buckle 631; The driving slot 146 includes a driving section 1461 for driving the clamping arm 144 to rotate and a clamping section 1462 for forcing the clamping arm 144 to always clamp the buckle 631 when sliding; In addition, the elastic clamping portion 145 is made of rubber or latex.

[0046] Further, if Figure 6 as well as Figure 10-11 As shown, the detection mechanism 5 includes a spray assembly 51 arranged below the suspension conveyor line 11 and used to spray water on the outer surface of the low-detonation-velocity emulsion explosive 6, a shaking assembly 52 arranged on the suspension conveyor line 11 and used to force the telescopic rod 13 to slide back and forth to generate shaking when the spray assembly 51 sprays water, a first collecting assembly 53 arranged in the spray assembly 51 and used to collect the surface image of the low-detonation-velocity emulsion explosive 6, a drying assembly 54 arranged in the spray assembly 51 and used to dry the low-detonation-velocity emulsion explosive 6, a first output assembly 55 and a film removal assembly 56 arranged in sequence outside the spray assembly 51 along the conveying direction of the suspension conveyor line 11, the first output assembly 55 is used to output qualified products, and the film removal assembly 56 is used to remove the outer diaphragm 63 of unqualified products.

[0047] In this embodiment, by providing a shaking component 52, it is convenient for the agent on the explosive body 61 to move to the inner wall of the inner diaphragm 611 through the swimming cavity 623, and the water sprayed by the spray component 51 on the outside of the outer diaphragm 63 is allowed to flow to make the coverage more complete. After the first collecting component 53 collects the surface of the inner diaphragm 611 for inspection, qualified products are output through the first output component 55, and unqualified products are removed by the membrane removal component 56 to remove the outer diaphragm 63 and re-enter the assembly line for production.

[0048] In detail, when in use, after the hanging conveyor line 11 conveys the low detonation velocity emulsion explosive 6 to the spray assembly 51, the first collection assembly 53 performs a first collection and detection on the surface of the low detonation velocity emulsion explosive 6, and then the outer diaphragm 63 of the low detonation velocity emulsion explosive 6 with relatively large damage is directly sent to the film removal assembly 56 for removal and then re-enters the production line for production, so as to prevent excessive water from entering the outer diaphragm 63 and contaminating the reagent on the explosive body 61. After the low detonation velocity emulsion explosive 6 without damage is uniformly sprayed with water on the outside of the outer diaphragm 63 by the spray assembly 51 in cooperation with the shaking assembly 52, the surface of the low detonation velocity emulsion explosive 6 is collected and detected for the second time by the first collection assembly 53 and the surface of the outer diaphragm 63 is dried by the drying assembly 54. The low detonation velocity emulsion explosive 6 without color change is a qualified product and can be output through the first output assembly 55. The low detonation velocity emulsion explosive 6 with color change is an unqualified product and enters the film removal assembly 56 for removal and then re-enters the production line for production.

[0049] It should be noted that the spray component 51 can be a structure of a pump plus a nozzle for spraying water, and the drying component 54 can be a structure of a negative pressure machine plus an air nozzle for jetting air. Therefore, the spray component 51 and the drying component 54 themselves and the installation method are all existing technologies and will not be described in detail here.

[0050] Further, if Fig.10 As shown, the shaking assembly 52 includes a support frame 521 arranged on the suspension conveyor line 11, a driving rack 522 arranged on the support frame 521, and a driving rod 523 arranged on the telescopic rod 13 and slidably connected to the driving rack 522.

[0051] In this embodiment, by setting the driving rack 522 to cooperate with the driving rod 523, the telescopic rod 13 is forced to slide in the direction away from the grabbing assembly 14 during the conveying process of the suspension conveyor line 11. Then, the telescopic rod 13 cooperates with the elastic member 15 to slide in the direction close to the grabbing assembly 14, and so on. The low detonation velocity emulsion explosive 6 is able to vibrate with the telescopic rod 13.

[0052] It should be noted that there are two driving racks 522, which are located on both sides of the telescopic rod 13. The corresponding telescopic rod 13 is provided with two driving rods 523 respectively cooperating with the corresponding driving racks 522 to improve the stability of the device.

[0053] Further, if Figure 11-Figure 12 As shown, the membrane removal assembly 56 includes a mounting frame 561 arranged on the first output assembly 55, a support barrel 562 movably arranged on the mounting frame 561 and used to support the low-detonation velocity emulsion explosive 6, an opening 563 formed at the lower end of the support barrel 562 and used for the buckle 631 at the lower end of the outer diaphragm 63 to extend out, and a cutter 564 movably arranged outside the lower end of the support barrel 562 and used to cut the outer diaphragm 63 to cut off the buckle 631.

[0054] In this embodiment, the movable support barrel 562 is provided to support the low-detonation-velocity emulsion explosive 6 and cooperate with the cutter 564 to cut off the buckle 631 extending from the opening 563, thereby cooperating with the conveying mechanism 1 to realize the removal of the damaged outer diaphragm 63.

[0055] In detail, when in use, after the hanging conveyor line 11 conveys the low-detonation-velocity emulsion explosive 6 to the top of the support barrel 562, the telescopic rod 13 is extended to convey the low-detonation-velocity emulsion explosive 6 into the support barrel 562 until the buckle 631 at the lower end of the outer diaphragm 63 extends out of the opening 563, and then the cutter 564 slides to cut off the buckle 631 extending out of the opening 563, and the telescopic rod 13 is shortened to pull the outer diaphragm 63 out of the upper end of the support barrel 562 for removal, and finally the support barrel 562 slides with the mounting frame 561 in the direction away from the telescopic rod 13, and the grabbing assembly 14 is opened to throw away the removed outer diaphragm 63, and then the support barrel 562 slides with the mounting frame 561 in the direction close to the telescopic rod 13, and the grabbing assembly 14 cooperates with the telescopic rod 13 to grab the buckle 631 on the explosive body 61, and then re-conveys it to the assembly line for assembly and production of the outer diaphragm 63.

[0056] It should be noted that a waste box 565 for collecting waste of the outer diaphragm 63 is provided below the support barrel 562 .

[0057] Further, if Figure 13-Figure 14 As shown, the coating mechanism 3 includes a storage tank 31 arranged below the conveying mechanism 1 and used to store the agent, a support tube 32 movably arranged on the storage tank 31 and used to support the explosive body 61 to be inserted into the agent, a plurality of arrays formed on the support tube 32 and used for the agent to enter the channel 33 attached to the surface of the explosive body 61, a second acquisition component 34 arranged above the storage tank 31 and used to collect the surface image of the explosive body 61 after the agent is attached, and a second output component 35 arranged on the outside of the storage tank 31 and used to output unqualified explosive bodies 61.

[0058] In this embodiment, a support tube 32 is provided to support the explosive body 61 to be inserted into the reagent and cooperate with the channel 33 so that the reagent is evenly attached to the outer surface of the explosive body 61. Then, the second collection component 34 is used to collect the surface of the explosive body 61 for inspection. Unqualified products are output through the second output component 35, and qualified products enter the next production.

[0059] In detail, when in use, the hanging conveyor line 11 conveys the explosive body 61 to the top of the support tube 32, and the second collection component 34 performs the first collection and detection on the surface of the explosive body 61, and then directly inputs the explosive body 61 with greater damage into the second output component 35 for output, so as to avoid wasting reagents. The explosive body 61 without damage is inserted into the reagent along with the support tube 32, and the reagent enters the support tube 32 through the channel 33 and adheres to the outside of the explosive body 61. Then, the explosive body 61 is pulled out of the reagent along with the support tube 32, and the reagent in the support tube 32 flows out naturally through the channel 33, so that the reagent outside the explosive body 61 is evenly attached. Finally, the second collection component 34 performs the second collection and detection on the surface of the explosive body 61. The explosive body 61 without color change is a qualified product and enters the next production, and the explosive body 61 with color change is an unqualified product and is output through the second output component 35.

[0060] It should be noted that the lower end of the support tube 32 is a tapered structure 321, which facilitates the insertion of the support tube 32 into the medicine; The first acquisition component 53 and the second acquisition component 34 are both cameras arranged in a matrix, and the first output component 55 and the second output component 35 are both conveyor belts, which are existing technologies and will not be described in detail here.

[0061] Further, if Figure 3-Figure 5 as well as Fig.16 As shown, the film sleeve assembly 41 includes a bagging groove 411 formed on the punching assembly 43, a conveying roller 412 movably arranged in the bagging groove 411 and used to convey the outer diaphragm 63, at least two suction cups 413 opened and closed in the bagging groove 411 and used to open the outer diaphragm 63, and at least four hooks 414 opened and closed in the bagging groove 411 and used to further open the outer diaphragm 63, thereby facilitating the support body 621 to enter the inner diaphragm 611.

[0062] In this embodiment, the outer membrane 63 is positioned and opened in the bagging groove 411 by providing a conveying roller 412 in cooperation with the suction cup 413 and the hook 414, so as to facilitate the subsequent connection of the support body 621 and the installation of the explosive body 61.

[0063] In detail, when in use, the conveying rod moves to clamp the outer diaphragm 63 and conveys its upper end upward to the opening of the bagging groove 411. The suction cup 413 attracts the outer diaphragm 63 to open and the conveying rod moves away from the outer diaphragm 63. The punching assembly 43 is able to cut off the lower end of the outer diaphragm 63 and punch and seal it, and then the hook 414 is able to rotate to further open the outer diaphragm 63.

[0064] It should be noted that the hook 414 further opens the outer membrane 63 and then cooperates with the bagging groove 411 to clamp the outer membrane 63 to prevent the outer membrane 63 from being dislocated and moving to affect the bagging; In addition, the punching assembly 43 used to punch the buckles 631 at both ends of the outer diaphragm 63 can be based on the same principle as the buckles 631 at both ends of the inner diaphragm 611. Therefore, the punching assembly 43 itself and the installation method are both existing technologies and will not be described in detail here.

[0065] Further, if Figure 3 as well as Fig.16 As shown, the connecting component 42 includes a conveying member 421 arranged on the outside of the punching component 43 and used to convey the support part 62, a slide rail 422 rotatably arranged on the conveying member 421, an extension rod 423 slidably arranged on the slide rail 422, at least two support arms 424 opened and closed and arranged on the extension rod 423 and used to support the cover body 622, and a clamping member arranged in the bagging groove 411 and used to clamp the support body 621.

[0066] In this embodiment, a support arm 424 is provided to cooperate with the slide rail 422 and the extension rod 423 to transport the support portion 62 on the conveying member 421 to the inner diaphragm 611 in the bagging groove 411 and clamp it through the clamping member, so that the cover body 622 can be removed and it is not easy for the cover body 622 and the support body 621 to be misaligned, which facilitates subsequent connection.

[0067] In detail, when in use, the rotating slide rail 422 cooperates with the sliding extension rod 423 to move the support arm 424 to the conveying member 421, and the support arm 424 is able to support the cover body 622 and cooperate with the rotating slide rail 422 and the sliding extension rod 423 to convey the support part 62 to the inner diaphragm 611 in the bag groove 411 and clamp the support body 621 through the clamping member, and then the rotating slide rail 422 cooperates with the sliding extension rod 423 to disassemble the cover body 622 supported by the support arm 424 and the support body 621 clamped by the clamping member, and the conveying mechanism 1 is able to convey the explosive body 61 to the support body 621, and finally, after the cover body 622 and the support body 621 that have not been misplaced are accurately plug-in connected through the rotating slide rail 422 and the sliding extension rod 423, the punching assembly 43 is able to seal the upper end of the outer diaphragm 63 to complete the assembly.

[0068] It should be noted that a connection port 624 for connecting the explosive body 61 to the lead is formed on both the support body 621 and the cover body 622, so that the support arm 424 can support the cover body 622 by opening and supporting the inner wall of the connection port 624, thereby avoiding interference between the support arm 424 and the outer diaphragm 63 during assembly, and the buckle 631 on the inner diaphragm 611 is located in the connection port 624, so that the conveying mechanism 1 can grab the buckle 631 on the inner diaphragm 611 through the connection port 624; The clamping component may be a suction cup 413 in the membrane assembly 41, which can not only clamp the support body 621 inside the lower end of the outer diaphragm 63, but also attract the lower end of the outer diaphragm 63 to open so as to facilitate the punching assembly 43 to perform punching and sealing; In addition, the conveying member 421 is a progressive conveyor, which itself and the installation method are both existing technologies and will not be described in detail here.

During the testing process, the agent on the inner diaphragm 611 moves to the inner wall of the outer diaphragm 63 through the swimming cavity 623, and then judges whether the outer diaphragm 63 leaks the agent to determine whether it is qualified.
