Description

Technical Field

[0001] This invention relates to the field of emulsion explosives technology, and more particularly to a large-diameter emulsion explosive production system and method. Background Technology

[0002] Emulsion explosives are a new type of water-resistant industrial explosive, named for their creamy, paste-like appearance. Chemically, they belong to the ammonium nitrate class of explosives. Their unique water-in-oil structure distinguishes them from traditional explosives. They possess extremely high water resistance, allowing them to be used directly in water-filled holes and wet working surfaces for blasting. They are also insensitive to external stimuli such as impact and friction, ensuring high safety during production, transportation, storage, and use. Furthermore, they have a high explosive power, and their formula and density can be adjusted to meet different rock conditions and blasting requirements. Large-diameter emulsion explosives typically refer to industrial explosives with a cartridge diameter of 70mm or more, specifically designed for open-pit deep-hole blasting and large-diameter boreholes. In practical applications, they are usually used in packaged cartridge form.

[0003] Patent document CN223400265U discloses an upward-deep-hole mixed emulsion explosive anti-dropping device, belonging to the field of mine blasting technology. It includes a plastic cap and a blocking cylinder. The plastic cap is fixed to the top of the blocking cylinder with transparent adhesive. The top of the blocking cylinder is open, and its bottom is vertically cut into multiple segments that flare outwards to support the inner wall of the borehole. A filling cavity is formed between the outer periphery of the blocking cylinder and the inner wall of the borehole. Burlap sacks are filled in the top of the plastic cap and the filling cavity. The upward friction generated between the bottom of the blocking cylinder and the inner wall of the borehole prevents the mixed emulsion explosive from falling out of the borehole. The mixed emulsion explosive is supported by the friction between the bottom of the blocking cylinder and the inner wall of the borehole. Furthermore, the filling of the top of the plastic cap and the filling cavity between the blocking cylinder and the borehole with burlap sacks further prevents the mixed emulsion explosive from falling out of the borehole.

[0004] However, in actual use, the inventors found that the existing large-diameter emulsion explosives have a large internal volume, and the oil-water phase interface in the emulsion matrix is ​​more susceptible to the effects of gravity and environmental changes, which may lead to demulsification or crystallization, accelerate the aging of the emulsion matrix, and may fail before the expiration date. In addition, the lower layer of explosive cartridges may be deformed under pressure during stacking and transportation, affecting the loading efficiency and blasting effect. Furthermore, the aforementioned anti-dropping device needs to be produced and transported separately during production, which increases production and transportation costs. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by setting up a forming mechanism in conjunction with an assembly mechanism to assemble the explosive body, sleeve, and end cap. This achieves the assembly of each component, supports the explosive body to prevent deformation under pressure, and ensures a relatively stable environment for the explosive body inside the sleeve. Furthermore, the forming mechanism, including a conveying component, a supporting component, and a cutting component, can accurately position the sleeve and cut it to form uniform slits and support arms, enabling synchronous production of each component and reducing production and transportation costs. This solves the problems of existing large-diameter emulsion explosives being easily affected by gravity and environmental changes, prone to deformation under pressure during transportation, and having high production and transportation costs.

[0006] To address the above technical problems, the following technical solution is adopted: A large-diameter emulsion explosive production system, comprising: A forming mechanism and an assembly mechanism disposed outside the forming mechanism, wherein the forming mechanism includes a conveying component, a support component movably and rotatably disposed between the conveying component and the assembly mechanism, and a cutting component movably disposed on the support component; Large-diameter emulsion explosives include an explosive body, a sleeve fitted over the explosive body, multiple slits spaced apart at one end of the sleeve, support arms formed on both sides of each slit, a ventilation channel disposed on the inner wall of the sleeve and communicating with the slits, and an end cap disposed at the end of the sleeve. The conveying assembly, in conjunction with the support assembly, positions and supports the sleeve through the ventilation channel. After the cutting assembly forms the incision and the support arm, the assembly mechanism, in conjunction with the support assembly, assembles the explosive body, the sleeve, and the end cap.

[0007] Preferably, the large-diameter emulsion explosive production system further includes a detection mechanism disposed outside the forming mechanism. The detection mechanism includes a support barrel rotatably disposed outside the forming mechanism, a support plate that is opened and closed outside the support barrel and forms a detection area with each other, and a spreading component that is movable outside the support barrel. The support barrel supports the explosive body on the assembly mechanism, and after the support plate is closed to form the detection area at the end of the explosive body, the spreading component unloads the sleeve on the support component into the detection area, and pushes the sleeve to squeeze the explosive body while spreading the support arm to the inner wall of the support plate.

[0008] Preferably, the assembly mechanism includes a conveying component disposed on the outside of the support barrel, a first guide plate disposed on both sides of the conveying component, a first positioning plate disposed at one end of the first guide plate and extending to the support barrel at the other end, and a feeding component disposed on the outside of the conveying component. The conveying component, in sequence with the first guide plate and the first positioning plate, positions and conveys the explosive body into the support barrel, while the feeding component positions and feeds the end cap to the outside of the support component.

[0009] Preferably, the feeding assembly includes a conveyor disposed below the support assembly, a V-shaped plate with both ends disposed on both sides of the conveyor, and a connecting pipe that is movable and rotatably disposed in the middle of the V-shaped plate. After the conveyor works with the V-shaped plate to position and convey the end cap, the connecting pipe is moved to connect the end cap, and then the connecting pipe is rotated to position and flip the end cap.

[0010] Preferably, the spreading assembly includes a clamping plate disposed on the support plate, a limiting plate movably disposed below the clamping plate, a spreading rod movably disposed outside the support plate, and a connecting rod movably disposed on the spreading rod. The clamping plate, in conjunction with the limiting plate, positions and clamps the sleeve on the support assembly. After the support arm is opened with the spreading rod, the connecting rod, in conjunction with the spreading rod, connects the end cap on the assembly mechanism to the sleeve, thereby stably opening the support arm within the detection area.

[0011] Preferably, the support assembly includes a support frame that is movably and rotatably disposed outside the conveying assembly, a positioning member that is movably or rotatably disposed on the support frame, and an elastic member disposed on the support frame; After the support frame is moved and rotated to support the sleeve on the conveying assembly, the elastic element forces the positioning element to position and connect the ventilation channel.

[0012] Preferably, the conveying assembly includes a conveying component, second guide plates disposed on both sides of the conveying component, a second positioning plate disposed on the second guide plate, a baffle disposed movably on the second positioning plate, and a drive roller disposed rotatably on the second positioning plate. The conveying component sequentially cooperates with the second guide plate and the second positioning plate to position and convey the sleeve. After the support frame is positioned and inserted into the sleeve in cooperation with the baffle, the support frame supports the sleeve and drives it to rotate through the drive roller until the positioning component connects to the ventilation channel.

[0013] Preferably, the cutting assembly includes a positioning seat disposed on the support frame, a limiting groove disposed on the positioning seat, and a plurality of cutting blades movably disposed on the support frame; When the assembly mechanism assembles the end cap at one end of the sleeve, it pushes the other end of the sleeve to be positioned and connected in the limiting groove of the positioning seat, thereby moving the cutter to position and cut the incision.

[0014] This application also provides a method for producing emulsion explosives, based on the above-mentioned large-diameter emulsion explosive production system, comprising the following steps: Step 1: Forming process. After the conveying component and the support component position and support the sleeve through the ventilation channel, the assembly mechanism assembles the end cap while positioning and squeezing one end of the sleeve. Then, the cutting component positions and cuts the other end of the sleeve to form the cut and the support arm. Step 2: Inspection process. After the support barrel and the support plate support the explosive body and the sleeve respectively, the spreading component spreads the support arm to the inner wall of the inspection area and flips the support barrel to achieve the support effect of the support arm when the explosive body is facing up and down. Step 3: Assembly process. The sleeve and the explosive body are moved out in sequence. After the sleeve is supported by the support plate, the assembly mechanism assembles the explosive body into the sleeve until the spreading component forces the support arm to retract in the opposite direction. Then the end cap is assembled to fix the support arm. Step 4: Packing process. The support plate and the support barrel rotate downwards to pour the assembled large-diameter emulsion explosive into the packaging mechanism, and then the packaging mechanism horizontally packs the large-diameter emulsion explosive into the packaging box.

[0015] Preferably, the packaging mechanism includes a support base disposed below the support barrel, a clamping arm that is openable and movable on the support base, and a tipping bucket that is movable and rotatably disposed outside the support base; After the support base, in conjunction with the clamping arm, positions and clamps the large-diameter emulsion explosive poured from the support bucket, the clamping arm moves to vertically push the large-diameter emulsion explosive into the packaging box on the tipping bucket, and then the tipping bucket is rotated to flip the large-diameter emulsion explosive to a horizontal state.

[0016] The beneficial effects of this invention are: (1) In this invention, a sleeve is set on the outside of the explosive body for support, so as to avoid the explosive body being deformed by pressure during stacking and transportation, which would lead to demulsification or crystallization, affecting the charging efficiency and blasting effect. At the same time, the end cap is used to ensure that the internal environment of the sleeve is relatively stable, and the cut and ventilation channel are used to ensure that the explosive body has a certain air permeability, reduce the aging of the emulsion matrix, and ensure that the explosive body is effective within the shelf life. At the same time, the support arm is used to work with the sleeve and end cap (i.e. anti-drop device) to squeeze and support the explosive body in the borehole during blasting, thereby improving the blasting effect. (2) In this invention, by setting up a forming mechanism including a conveying component, a supporting component and a cutting component, the sleeve can be accurately positioned and cut to form a uniform cut and a supporting arm. Then, in conjunction with the assembly mechanism, the explosive body, the sleeve and the end cap are assembled. The production process is precisely positioned and cut by machinery, which replaces manual handling and reduces operational risks. In addition, the system integrates multiple processes into one, which greatly improves production efficiency. The anti-dropping device is produced synchronously with the explosive body and assembled with each other, which reduces material turnover time and ensures the consistency and reliability of product quality, and reduces production and transportation costs. (3) In this invention, a support bucket is set to support the explosive body, and a support plate is used to form a detection area that mimics a blast hole at the end of the explosive body. Then, the support arm is mechanically expanded to the inner wall of the support plate by the expansion component, mimicking the state when a large-diameter emulsion explosive is used. This allows for real-time screening of defects such as brittle support arm or insufficient support effect caused by poor cutting in the early stage. At the same time, the cuts between each support arm are enlarged to ensure good air permeability. Quality inspection is brought forward to the assembly process, preventing unqualified products from flowing into the final product and significantly enhancing the adaptability of the production system and the reliability of the final product. In summary, the large-diameter emulsion explosives produced by this system are less affected by gravity and environmental changes, and are less prone to deformation during transportation, thus reducing production and transportation costs. This makes it particularly suitable for the field of emulsion explosives technology. Attached Figure Description

Detailed Implementation The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] Example 1 like Figures 1-5 As shown, a large-diameter emulsion explosive production system includes: The molding mechanism 2 and the assembly mechanism 3 disposed outside the molding mechanism 2, wherein the molding mechanism 2 includes a conveying component 21, a support component 22 movably and rotatably disposed between the conveying component 21 and the assembly mechanism 3, and a cutting component 23 movably disposed on the support component 22; The large-diameter emulsion explosive includes an explosive body 11, a sleeve 12 sleeved outside the explosive body 11, multiple slits 13 formed at intervals at one end of the sleeve 12, support arms 14 formed on both sides of each slit 13, a ventilation channel 15 disposed on the inner wall of the sleeve 12 and connected to the slits 13, and an end cap 16 disposed at the end of the sleeve 12. The conveying component 21, together with the support component 22, positions the support sleeve 12 through the ventilation channel 15. After the cutting component 23 cuts to form the cut 13 and support arm 14, the assembly mechanism 3, together with the support component 22, assembles the explosive body 11, the sleeve 12 and the end cap 16.

[0032] In this embodiment, a sleeve 12 is provided on the outside of the explosive body 11 for support, which avoids the explosive body 11 from being deformed by pressure during stacking and transportation, which would lead to demulsification or crystallization and affect the charging efficiency and blasting effect. At the same time, the end cap 16 is used to ensure that the internal environment of the sleeve 12 is relatively stable, and the cut 13 and ventilation channel 15 are used to ensure that the explosive body 11 has a certain degree of air permeability, reduce the aging of the emulsion matrix, and ensure that the explosive body 11 is effective within its shelf life. In addition, the support arm 14 is used to work with the sleeve 12 and end cap 16 (i.e., anti-drop device) to squeeze and support the explosive body 11 in the borehole during blasting, thereby improving the blasting effect. By setting up the forming mechanism 2, which includes a conveying component 21, a supporting component 22, and a cutting component 23, the sleeve 12 can be accurately positioned and cut to form uniform slits 13 and supporting arms 14. Then, in conjunction with the assembly mechanism 3, the explosive body 11, the sleeve 12, and the end cap 16 can be assembled. The production process uses precise mechanical positioning and cutting to replace manual handling, reducing operational risks. In addition, the system integrates multiple processes into one, which greatly improves production efficiency. The anti-drop device is produced and assembled with the explosive body 11 simultaneously, reducing material turnover time and ensuring the consistency and reliability of product quality, thereby reducing production and transportation costs.

[0033] It should be noted that the inner side of the end cap 16 is provided with an insertion part 161 that is inserted into the sleeve 12, a connecting groove 162 for connecting the sleeve 12 wall or multiple support arms 14, and a notch 163 formed on the outer side of the end cap 16 at the position corresponding to the insertion part 161. The insertion part 161 and the connecting groove 162 improve the stability of the connection, while the notch 163 reduces the amount of material used and lowers the production cost.

[0034] Furthermore, such as Figures 5-6 As shown, the support assembly 22 includes a support frame 221 that is movably and rotatably disposed on the outside of the conveying assembly 21, a positioning member 222 that is movably or rotatably disposed on the support frame 221, and an elastic member disposed on the support frame 221. After the support frame 221 is moved and rotated to support the sleeve 12 on the conveying assembly 21, the elastic element forces the positioning element 222 to position and connect the ventilation channel 15.

[0035] In this embodiment, the support frame 221 is moved to the conveying component 21 and precisely inserted into the sleeve 12. Then, by rotating and adjusting the posture of the sleeve 12 and continuously applying elastic force with the elastic element, the positioning element 222 is forced to automatically engage in the ventilation channel 15 inside the sleeve 12, achieving precise fitting between the two. The support component 22, through the combination of elastic positioning and multi-degree-of-freedom movement, achieves efficient support and precise reference positioning for the sleeve 12, laying a precision foundation for subsequent cutting and assembly processes.

[0036] It should be noted that the support end of the support frame 221 is adapted to the inner wall of the sleeve 12 to improve the support effect and stability. The positioning element 222 is a rod-shaped structure inserted into the ventilation channel 15. In addition, the elastic element can be a helical spring, torsion spring, etc., which are existing technologies and are not shown in the attached drawings, so they will not be described in detail here.

[0037] Furthermore, such as Figures 5-6 As shown, the conveying assembly 21 includes a conveying component 211, a second guide plate 212 disposed on both sides of the conveying component 211, a second positioning plate 213 disposed on the second guide plate 212, a baffle 214 movably disposed on the second positioning plate 213, and a drive roller 215 rotatably disposed on the second positioning plate 213. The conveying component 211 sequentially positions the conveying sleeve 12 in conjunction with the second guide plate 212 and the second positioning plate 213, and in conjunction with the baffle 214, positions the support frame 221 after it is inserted into the sleeve 12. The support frame 221 supports the sleeve 12 and drives it to rotate through the drive roller 215 until the positioning component 222 connects to the ventilation channel 15.

[0038] In this embodiment, by setting the second guide plate 212 and the second positioning plate 213 on both sides of the conveyor 211 to form a tapered channel, the axial positioning of the sleeve 12 during the conveying process and the height alignment with the subsequent station are ensured. After the sleeve 12 is positioned, the movable baffle 214 extends to axially limit the end of the sleeve 12 and form a rigid stop. At this time, the support frame 221 moves and inserts into the inner wall of the sleeve 12. The reverse support force of the baffle 214 ensures that the insertion process is smooth and coaxial, and avoids the sleeve 12 being pushed away from the predetermined station. After the support frame 221 is fully inserted and supports the sleeve 12, the baffle 214 is reset, the drive roller 215 is attached and drives the sleeve 12 to rotate slowly until the positioning part 222 on the support frame 221 automatically gets into the ventilation channel 15 inside the sleeve 12 by the elastic force. This achieves the precise positioning of the support frame 221 and the sleeve 12, and provides a stable workpiece reference for subsequent high-precision cutting.

[0039] It should be noted that the conveying assembly 31, the conveying component 341, and the conveying component 211 can be a conveyor belt structure, and their structure and installation method are existing technologies, which will not be described in detail here. In addition, this application does not limit the driving method of the baffle 214, and only one structure is provided below for reference: A push rod 216, which is rotatably disposed on the outside of the second positioning plate 213 and connected to the baffle 214 at one end, a push ramp 217 disposed at the other end of the push rod 216 and extending to the inside of the second positioning plate 213, and a spring disposed on the second positioning plate 213 for forcing the baffle 214 to move out of the second positioning plate 213 with the push rod 216, are inserted into the other end of the sleeve 12 after the support frame 221 pushes the baffle 214 to rotate with the push rod 216 through the push ramp 217 and restricts one end of the sleeve 12.

[0040] Furthermore, such as Figures 5-6 as well as Figures 10-11 As shown, the cutting assembly 23 includes a positioning seat 231 disposed on the support frame 221, a limiting groove 232 disposed on the positioning seat 231, and a plurality of cutters 233 movably disposed on the support frame 221; When the assembly mechanism 3 assembles the end cap 16 at one end of the sleeve 12, it pushes the other end of the sleeve 12 to be positioned and connected in the limiting groove 232 of the positioning seat 231, and then moves the cutter 233 to position and cut out the cut 13.

[0041] In this embodiment, by setting the positioning seat 231 in conjunction with the limiting groove 232, the sleeve 12 is clamped by the driving force of the assembly process, achieving seamless connection and precision self-locking between processes, forming stable radial constraint and axial stop. Since the sleeve 12 has been precisely positioned by the limiting groove 232, and its internal ventilation channel 15 has been locked in phase by the positioning part 222 of the support component 22, when the multiple cutters 233 move radially, they can strictly cut into the pipe wall along the predetermined path, forming cuts 13 of consistent size and uniform distribution at the end. This dual guarantee of phase locking and rigid support completely avoids the common problems of deformation, vibration or cut 13 deviation when cutting thin-walled sleeves 12. At the same time, the cutting process and the end cap 16 assembly process are highly coordinated, which significantly improves the coordination of production cycle while ensuring the accuracy of cut 13 and the forming quality of support arm 14.

[0042] It should be noted that the multiple cutters 233 are interconnected, which facilitates simultaneous driving, improves the synchronization of cutting, and standardizes the forming of the cut 13 and the support arm 14.

[0043] Furthermore, such as Figures 7-17 As shown, the large-diameter emulsion explosive production system also includes a detection mechanism 4 located outside the forming mechanism 2. The detection mechanism 4 includes a support barrel 41 rotatably located outside the forming mechanism 2, a support plate 42 that is opened and closed outside the support barrel 41 and forms a detection area 43 between them, and a spreading component 44 that is movable outside the support barrel 41. The support barrel 41 supports the explosive body 11 on the assembly mechanism 3, and after the support plate 42 closes to form a detection area 43 at the end of the explosive body 11, the support assembly 44 opens to allow the sleeve 12 on the support assembly 22 to be fed into the detection area 43, and the support arm 14 is opened to the inner wall of the support plate 42 while pushing the sleeve 12 to squeeze the explosive body 11.

[0044] In this embodiment, a support barrel 41 is set to support the explosive body 11, and a detection area 43 mimicking a blast hole is formed at the end of the explosive body 11 with the support plate 42. Then, the support arm 14 is mechanically expanded to the inner wall of the support plate 42 by the expansion component 44, mimicking the state when a large-diameter emulsion explosive is used. This allows for real-time screening of defects such as brittleness or insufficient support effect of the support arm 14 caused by poor cutting in the early stage. At the same time, the cuts 13 between each support arm 14 are enlarged to ensure good air permeability. Quality inspection is brought forward to the assembly process, preventing unqualified products from flowing into the final product, and significantly enhancing the adaptability of the production system and the reliability of the final product.

[0045] It should be noted that when the support arm 14 slides with the sleeve 12 during the testing process, it proves that the support arm 14 is not supporting enough, and the support plate 42 can be opened to remove the unqualified sleeve 12. In addition, the inner wall of the support plate 42 can be a rock slab structure or a rubber structure. The rock slab allows the testing area 43 to imitate the inner wall of a blast hole drilled in rock, and the rubber allows the testing area 43 to imitate the inner wall of a blast hole drilled in soil.

[0046] Furthermore, such as Figure 7 as well as Figures 10-15 As shown, the assembly mechanism 3 includes a conveying assembly 31 disposed on the outside of the support barrel 41, a first guide plate 32 disposed on both sides of the conveying assembly 31, a first positioning plate 33 disposed at one end on the first guide plate 32 and extending to the support barrel 41 at the other end, and a feeding assembly 34 disposed on the outside of the conveying assembly 31. The conveying component 31, in sequence with the first guide plate 32 and the first positioning plate 33, positions and conveys the explosive body 11 into the support barrel 41, while the feeding component 34 positions and feeds the end cap 16 to the outside of the support component 22.

[0047] In this embodiment, the conveying component 31, together with the first guide plates 32 on both sides and the first positioning plate 33 extending to the support barrel 41, forms a tapered guide channel, smoothly and accurately guiding the explosive body 11 into the predetermined position of the support barrel 41. This process does not require complex visual recognition or active correction mechanisms. The purely mechanical structure ensures the positioning consistency and repeatability accuracy in efficient continuous production. In addition, the feeding component 34, located outside the conveying component 31, independently completes the automated feeding of the end cap 16 and accurately positions it outside the support component 22, preparing it for subsequent pressing assembly. The rigid combination of mechanical limiting and guiding ensures the coaxiality and fitting accuracy of the explosive body 11, sleeve 12, and end cap 16 during final assembly, avoiding the skewing or damage that may be caused by manual assembly. With simple and efficient mechanical logic, high precision, high reliability, and complete automation of the large-diameter emulsion explosive packaging process are achieved.

[0048] It should be noted that when the explosive body 11 is removed from the support barrel 41, it is conveyed out by the conveying component 31. Then, the assembly mechanism 3 pushes the explosive body 11 into the sleeve 12. This process is achieved by the sleeve 12 rotating with the support plate 42 to the conveying component 31. Under the guidance of the support arm 14, the conveying component 31 conveys the explosive body 11 into the sleeve 12. In addition, the support barrel 41 is set on the first positioning plate 33, which facilitates the connection and positioning between the two and the positioning and feeding of the explosive body 11. The structure is simpler, more compact, and easier to use.

[0049] Furthermore, such as Figures 7-8 as well as Figures 10-13 As shown, the feeding assembly 34 includes a conveyor 341 disposed below the support assembly 22, a V-shaped plate 342 disposed on both sides of the conveyor 341, and a connecting pipe 343 disposed in the middle of the V-shaped plate 342. After the conveyor 341 and the V-shaped plate 342 position the conveyor end cover 16, the moving connecting pipe 343 connects the end cover 16, and then the connecting pipe 343 rotates to position and flip the end cover 16.

[0050] In this embodiment, the conveyor 341, guided by the V-shaped plate 342, is positioned during the conveying of the end cap 16, ensuring that the axis of the end cap 16 is aligned with the subsequent work station. Simultaneously, the moving and rotating connecting pipe 343 descends precisely, connecting and fixing the end cap 16 pneumatically or mechanically. Then, the end cap 16 rotates and flips with the connecting pipe 343. The entire process, through a sophisticated mechanical structure, greatly simplifies the need for robotic arms or complex flipping mechanisms, saves equipment space and costs, and realizes the automatic positioning, connection, and orientation flipping of the end cap 16. This solves the difficulties of adjusting the orientation of the end cap 16 and its susceptibility to damage in traditional production, and significantly improves the full automation level and product yield of the assembly mechanism 3.

[0051] It should be noted that the bottom of the V-shaped plate 342 is an arc-shaped structure that adapts to the outer ring surface of the end cap 16, improving the accuracy and stability of positioning; in addition, the connecting tube 343 is used to connect the insertion part 161 and / or the connecting groove 162 of the end cap 16, improving the stability and positioning accuracy of the connection and flipping of the end cap 16.

[0052] Furthermore, such as Figures 7-17 As shown, the spreading assembly 44 includes a limiting plate 442 disposed on the outside of the support barrel 41, a clamping plate 441 disposed on the support plate 42, a spreading rod 443 movably disposed on the outside of the support plate 42, and a connecting rod 444 movably disposed on the spreading rod 443. The limiting plate 442, together with the clamping plate 441, positions and clamps the sleeve 12 on the support assembly 22. After the support arm 14 is opened by moving the spreading rod 443, the connecting rod 444 connects to the upper end cover 16 of the assembly mechanism 3. The spreading rod 443 is moved to push the end cover 16 to connect inside the sleeve 12, thereby stably opening the support arm 14 in the detection area 43.

[0053] In this embodiment, the sleeve 12 on the support assembly 22 is precisely positioned by setting the limiting plate 442 and clamped firmly with the clamping plate 441 to ensure that the sleeve 12 does not shift or deflect during subsequent force application, thus establishing a rigid benchmark for the opening action. At the same time, the opening rod 443 is used to precisely push the support arm 14 at the end of the sleeve 12 to open and shape it. Then, the connecting rod 444 connects and the support end cap 16 is connected inside the sleeve 12 to stably support the support arm 14 inside the support plate 42, thereby realizing dynamic detection of the support stability of the support arm 14.

[0054] It should be noted that the connecting rod 444 is used to connect to the notch 163 on the end cap 16, thereby improving the stability and positioning accuracy of the connection to the end cap 16.

[0055] Furthermore, such as Figure 18 As shown, the large-diameter emulsion explosive production system also includes a packaging mechanism 5 located below the support barrel 41. The packaging mechanism 5 includes a support base 51 located below the support barrel 41, a clamping arm 52 that is openable and movable on the support base 51, and a tipping bucket 53 that is movable and rotatably located outside the support base 51. After the support base 51 and the clamping arm 52 position and clamp the large-diameter emulsion explosive poured out of the support bucket 41, the clamping arm 52 is moved to push the large-diameter emulsion explosive vertically into the packaging box on the tipping bucket 53, and then the tipping bucket 53 is rotated to flip the large-diameter emulsion explosive to a horizontal state.

[0056] In this embodiment, by setting up a support base 51 in conjunction with a clamping arm 52 and a tipping bucket 53, a fully automatic and seamless connection is achieved between the vertical discharge of finished large-diameter emulsion explosives from the support barrel 41 and the horizontal packing. After the support barrel 41 pours out the vertically positioned finished large-diameter emulsion explosives, the clamping arm 52 precisely closes on the support base 51 and clamps the large-diameter emulsion explosives, ensuring that the large-diameter emulsion explosives are smoothly delivered into the packaging box on the tipping bucket 53. This process is completely automated by machinery, avoiding the collision risks and low efficiency that may be caused by manual handling. After the explosives are delivered into the packaging box, the tipping bucket 53 drives the entire packaging box to rotate precisely 90 degrees, changing the explosives from a vertical position to the horizontal position required for final storage and transportation. The entire packing process ensures product integrity while achieving complete automation of finished product collection and logistics transfer.

[0057] It should be noted that the two ends of the large-diameter emulsion explosive abut against the inner walls of both sides of the packaging box, improving the stability of the large-diameter emulsion explosive packing and preventing misalignment, movement, or tipping. The packaging box is a cardboard box, and both the box itself and the installation method are existing technologies, not shown in the attached drawings, and will not be described in detail here. In addition, the outside of the tipping bucket 53 is also equipped with a box sealing machine for sealing the packaging box, improving the automation and integrity of the production system. Both the box itself and the installation method are existing technologies, not shown in the attached drawings, and will not be described in detail here.

[0058] Example 2 like Figures 1-5 as well as Figures 10-19 As shown, a method for producing emulsion explosives, based on a large-diameter emulsion explosive production system in Example 1, includes the following steps: Step 1: Molding process. After the conveying component 21 and the support component 22 position the support sleeve 12 through the ventilation channel 15, the assembly mechanism 3 assembles the end cap 16 and positions and extrudes one end of the sleeve 12. Then the cutting component 23 positions and cuts the other end of the sleeve 12 to form the cut 13 and the support arm 14. Step 2: Inspection process. After the support barrel 41 and the support plate 42 support the explosive body 11 and the sleeve 12 respectively, the expansion assembly 44 expands the support arm 14 to the inner wall of the inspection area 43, and in conjunction with the flipping of the support barrel 41, the support arm 14 is supported when the explosive body 11 is facing up and down. Step 3: Assembly process. The sleeve 12 and the explosive body 11 are moved out in sequence. After the sleeve 12 is supported by the support plate 42, the assembly mechanism 3 pushes the explosive body 11 into the sleeve 12 until the expansion component 44 forces the support arm 14 to retract. Then the end cap 16 is assembled to fix the support arm 14. Step 4: Packing process. The support plate 42 and the support barrel 41 rotate downwards to pour the assembled large-diameter emulsion explosive into the packaging mechanism 5. Then, the packaging mechanism 5 horizontally packs the large-diameter emulsion explosive into the packaging box.
