Description

Technical Field

[0001] This invention relates to the field of blasting device technology, and more specifically to a continuous winding system for detonating cord and an integrated connection system for explosive cartridges. Background Technology

[0002] In industrial blasting operations, detonating cord, as a key pyrotechnic component for transmitting detonation waves, plays a crucial role in determining the reliability and safety of the entire blasting network through its complete process from initial release and intermediate transport to final assembly with the explosive cartridge. Currently, this complete process is divided into two independent stages with technological gaps in engineering practice. The first stage is the transport and pre-treatment of the detonating cord. The cord needs to be released from a large storage drum and transported via a series of guide wheels. During this process, the cord continuously rubs against the metal wheel surfaces at high speed, easily accumulating heat and generating static electricity, posing a significant safety risk of ignition or accidental detonation. The common technical solution to this risk is to use an external, independent coolant or antistatic agent spraying system. These systems typically require additional electric pumps, storage tanks, and complex electrically controlled valves, significantly increasing equipment costs and energy consumption. Furthermore, it is difficult to precisely synchronize the spraying action with the actual operating speed of the detonating cord, often resulting in uneven agent coverage and significant waste. Additionally, failure to shut off the system promptly when the detonating cord stops can lead to agent accumulation. More seriously, current winding devices generally lack efficient, instantaneous mechanical overload protection mechanisms when faced with sudden obstruction of the detonation path or drum jamming. They often rely on electronic sensor detection combined with electromagnetic clutches, which inevitably suffers from delays in electrical signal processing and mechanical response. This makes them highly susceptible to tension surges that can cause the detonating cord to become taut or even break, directly impacting subsequent processes. The second stage involves the connection and assembly of the detonating cord and the explosive cartridge. The pre-treated detonating cord needs to be manually or mechanically transferred to another independent station for sequential tape winding (especially hot-melt pressure-sensitive tape used to fill the micro-pores at the interface), explosive cartridge placement, and final bundling. Existing technology often features fragmented improvements, either only achieving automatic winding or only supplying the explosive cartridge. Each process is driven by multiple independent motors, relying on complex programmable controllers for timing synchronization. In high-speed continuous operation, even small signal delays and servo errors accumulate, easily leading to imbalances in the core actions such as winding, unloading, and bundling, resulting in quality problems such as inaccurate explosive cartridge placement and insecure bundling. Crucially, the hot-melt pressure-sensitive adhesive tape needs to be pressed against the explosive cartridge within a brief viscous flow time window after heat activation to fully fill the grooves on the detonating cord surface and achieve a seal. However, the instability of the step-by-step operation and electronic control synchronization often results in the tape contacting the explosive cartridge only after the optimal adhesion state has passed, causing interface seal failure and severely affecting the reliability of detonation wave transmission. This mechanical separation between the two stages not only results in a large equipment footprint, complex control systems, and a rising failure rate, but also introduces new risks such as adhesive layer scraping and contamination and loss of positioning accuracy during process transitions, failing to meet the urgent needs of modern blasting engineering for efficient, safe, and high-quality continuous production.

[0003] Therefore, the inventors have proposed a continuous winding system for detonating cord and an integrated connection system for the explosive charge to solve the aforementioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a continuous winding and integrated connection system for detonating cord and explosive cartridge, so as to solve the technical problems of asynchronous conveying and cooling of detonating cord, lack of mechanical overload protection, and low efficiency caused by separation and difficulty in coordination of the detonating cord and explosive cartridge connection process.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A continuous winding and integrated connection system for detonating cord and explosive cartridge includes a winding device for the detonating cord and a connection device for the detonating cord and explosive cartridge. The detonating cord winding device includes a frame, a wheel assembly mounted on the frame, and a drum assembly for carrying the detonating cord; The wheel system assembly includes a first wheel, a buffer wheel, and an actuating wheel arranged sequentially along the detonating cord delivery path; the actuating wheel is coaxially connected to an actuator, which is connected to the first wheel and the buffer wheel respectively, and the actuator is used to convert the rotational power of the actuating wheel into a driving force for delivering the medium into the first wheel and the buffer wheel; The connection device between the detonating cord and the explosive cartridge includes a support frame and a rotating drum rotatably mounted on the support frame. The rotating drum has a hollow cylindrical structure with openings at both ends for the detonating cord to pass through. A tape winding unit includes a first winding disc eccentrically disposed on the outer periphery of the rotating drum. The first winding disc is used to carry the tape roll. The drum wall is provided with a tape inlet. The working end of the tape roll can pass through the tape inlet and enter the interior of the rotating drum to form a rubber-coated detonating cord. The medicine roll feeding unit includes a feeding tray that rotates synchronously with the rotary drum, and the feeding tray is provided with at least one unloading station for receiving medicine rolls. A binding unit is disposed at the end of the rotating drum corresponding to the direction in which the detonating cord extends, and is connected to the rotating drum to rotate synchronously with the rotating drum.

[0006] The beneficial effects of this invention are: This invention mechanically couples the actuating wheel with the detonating cord delivery path, directly converting the movement of the detonating cord into the rotational power of the actuating wheel. This power then drives the actuator to convert the rotational motion into hydraulic energy, pumping cooling medium and antistatic agent to the first and buffer wheels. This ensures that the supply rate of cooling and antistatic agents is strictly synchronized with the operating speed of the detonating cord, with automatic start and stop. This fundamentally solves the problems of agent waste, uneven coverage, and management difficulties caused by the asynchronous operation of traditional external cooling systems. Simultaneously, the medium seeps directly from the outlet through the internal channels of the friction wheel to the contact surface of the detonating cord, achieving efficient and uniform direct cooling and wetting. This significantly reduces the risk of localized high temperatures caused by frictional heat generation, improves operational safety, and the entire process requires no external power, making it energy-saving and environmentally friendly.

[0007] This invention integrates a tension overload protection and tension fluctuation buffering mechanism with instantaneous mechanical response. It creatively links the sliding displacement of the buffer wheel with the radial contraction mechanism of the drum assembly, as well as the floating and air pump functions of the second wheel. When the drum jams, causing a surge in detonating cord tension, the overload force compels the buffer wheel and the first sliding seat to slide. This displacement directly pulls the second shaft of the drum assembly through the slide rod and rotating ring, causing the extension unit to radially contract and the drum's outer diameter to decrease instantaneously. This releases the detonating cord length and buffers the overload tension. The entire process is a purely mechanical, instantaneous feedback mechanism, no longer relying on sensor-based electronic control systems, effectively preventing the detonating cord from breaking. Furthermore, the second wheel is floatingly mounted via a telescopic elastic element, absorbing micro-tension fluctuations along the path in real time to maintain stable delivery. The floating process of the second wheel also drives the built-in air pump to deliver compressed air to the third wheel to purge and cool the detonating cord, further improving cleaning and cooling effects and utilizing the energy of the buffering motion. The structure is compact and highly practical.

[0008] This invention, through a single-axis drive and integrated mechanical synchronization structure design, fundamentally solves the technical problems of difficult process coordination and easy mismatch of electrical control synchronization in traditional step-by-step operation modes. The rotating drum, as a single rotating power source, rigidly links the tape winding unit, the explosive cartridge unloading unit, and the binding unit, achieving absolute synchronization in time and space for the three core processes of winding, unloading, and binding. This purely mechanical, hard-connection synchronization mechanism completely eliminates the electrical signal delay, servo response error, and program cycle fluctuations caused by independent multi-motor drives. It ensures that, under high-speed continuous production conditions, the explosive cartridge is accurately delivered to the detonating cord that has been coated with adhesive and whose adhesive layer is still in its optimal viscous flow state, and is immediately and reliably bound. This not only significantly improves the speed and cycle stability of the production process but also, in principle, ensures that the hot melt adhesive can fully fill the microscopic defects on the surface of the detonating cord, forming a dense sealing interface, thereby significantly improving the reliability and safety of the blasting network connection.

[0009] This invention, through highly integrated functional modules and ingenious mechanical structure, achieves fully automated and integrated operation from tape pretreatment, continuous coating of detonating cord, automatic feeding and precise positioning of explosive cartridges to final binding. The device integrates a thermal activation unit for tape pretreatment, a tilting guide groove and a self-locking baffle mechanism for precise guidance and pre-positioning of explosive cartridges, and an eccentric winding disc for automatic release and winding of the binding thread. The entire system is compact, requiring only one drive motor, avoiding complex robotic arms, multi-axis positioning systems, and sophisticated electronic control synchronization programs, significantly reducing manufacturing costs, control complexity, and failure rates. Simultaneously, the continuous assembly line operation mode greatly reduces manual intervention, increasing production efficiency several times over while ensuring consistency and traceability of product connection quality. It provides an efficient, stable, and reliable automated production solution for the industrial blasting field, possessing outstanding practical value and broad application prospects.

Detailed Implementation

[0012] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0013] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0014] This embodiment proposes a continuous winding system for detonating cord and an integrated connection system for the explosive charge, such as... Figures 1 to 15 As shown, it includes a winding device for detonating cord and a connection device for detonating cord and explosive cartridge; wherein, the winding device for detonating cord includes a frame A1, a wheel assembly A2 mounted on the frame A1, and a drum assembly A3 for carrying detonating cord A4.

[0015] Wheel assembly A2 includes a first rotating wheel A21, a buffer rotating wheel A22, and an actuating wheel A23 arranged sequentially along the conveying path of the detonating cord A4. All three wheels are rotatably mounted on frame A1. An actuator A24 is coaxially connected to the actuating wheel A23. The actuator A24 is connected to both the first rotating wheel A21 and the buffer rotating wheel A22, and is used to convert the rotational power of the actuating wheel A23 into power directed into the first rotating wheel A21 and the buffer rotating wheel A22. The driving force for conveying the medium; the buffer wheel A22 is mounted on the first sliding seat A25, the first sliding seat A25 is slidably mounted on the frame A1, and the first sliding seat A25 has the tendency to drive the buffer wheel A22 away from the first wheel A21; the drum assembly A3 is connected to the first sliding seat A25, and the first sliding seat A25 can drive the drum assembly A3 to retract radially. During the conveying of the detonating cord A4, the rotation of the actuating wheel A23 synchronously drives the first wheel A21 to cool the contacting detonating cord A4.

[0016] In this embodiment, when the detonating cord A4 is conveyed around the wheel train assembly A2, a traction machine (not shown) is connected to the end of the detonating cord A4. The purpose of the traction machine is to move the detonating cord A4. When the detonating cord A4 is moved, it will drive the actuating wheel A23 in the drive wheel train assembly A2 to rotate. The rotational power of the actuating wheel A23 is converted into hydraulic energy by the coaxial actuator A24, thereby synchronously and automatically delivering cooling medium and antistatic agent to the inside of the first rotating wheel A21 and the buffer rotating wheel A22, so that the detonating cord A4 is cooled in time when it comes into contact with the first rotating wheel A21. At the same time, the first sliding seat A25 on which the buffer rotating wheel A22 is installed maintains a stable position under the action of an elastic element (such as a tension spring A253), maintaining the normal path and tension of the detonating cord A4. When the drum assembly A3 jams, causing the detonating cord A4 to have an abnormally increased tension, the increased tension forces the buffer wheel A22 and the first sliding seat A25 to overcome the tension of the elastic element and produce a sliding displacement. This displacement is transmitted to the drum assembly A3, forcing the extension unit A8 of the drum assembly A3 to produce a radial contraction, reducing the outer diameter of the drum assembly A3 and releasing part of the winding length, thereby efficiently buffering the overload tension and preventing the detonating cord A4 from being pulled apart. The entire process does not require external power or complex control, realizing complete self-drive and instantaneous mechanical feedback from power acquisition, safe handling to overload protection.

[0017] In a preferred embodiment, the first rotating wheel A21 and the buffer rotating wheel A22 have the same structure, both being friction wheels. Each friction wheel includes two limiting rings A211, a contact shaft A212, and a mounting shaft A213. The contact shaft A212 is disposed between the two limiting rings A211, and both ends of the contact shaft A212 are connected to the two limiting rings A211. One end of the mounting shaft A213 passes through one of the limiting rings A211 and is coaxially rotatably connected to the contact shaft A212. The mounting shaft A213 is mounted on the frame A1. A liquid inlet channel A214 is provided inside the mounting shaft A213, and a diversion channel A215 is provided inside the contact shaft A212. Several liquid outlet holes A216 are provided on the outer periphery of the contact shaft A212, and each liquid outlet hole A216 communicates with the diversion channel A215. The liquid inlet channel A214 communicates with the diversion channel A215.

[0018] When actuator A24 introduces coolant or antistatic agent into inlet channel A214, the medium first flows into distribution channel A215 inside contact shaft A212, which is coaxially rotatably connected to mounting shaft A213. Contact shaft A212, driven by friction from detonating cord A4, can freely rotate relative to the stationary mounting shaft A213. Internal distribution channel A215 acts as a distribution chamber, evenly distributing the medium to several outlet holes A216 arranged circumferentially on the shaft. Because detonating cord A4 is constrained by two... Between the fixed limiting rings A211, and always in frictional contact with the outer surface of the rotating contact shaft A212, the coolant or antistatic agent seeping from the liquid outlet A216 can be directly, continuously and evenly coated or soaked in the contact area of ​​the detonating cord A4, achieving efficient direct cooling and antistatic treatment; throughout the process, the limiting rings A211 not only guide and prevent the detonating cord A4 from deviating, but also form a local cooling chamber, achieving the effect of cooling the detonating cord A4.

[0019] In a preferred embodiment, a rotating shaft A241 is coaxially fixedly connected to the upper part of the actuating wheel A23, and the rotating shaft A241 is rotatably mounted on the frame A1; the actuator A24 includes an actuating housing A242, a first piston cylinder A243, a second piston cylinder A244, and an actuating unit A245. The actuating housing A242 is fixedly mounted on the frame A1, the actuating unit A245 is rotatably disposed inside the actuating housing A242, the first piston cylinder A243 and the second piston cylinder A244 are fixedly disposed on the actuating housing A242, and the first piston cylinder A243 is connected to a first inlet pipe A246 and a first outlet pipe. A247, the first inlet pipe A246 is equipped with a first check valve, and the first outlet pipe A247 is equipped with a second check valve; the second piston cylinder A244 is connected to the second inlet pipe A248 and the second outlet pipe A249, the second inlet pipe A248 is equipped with a third check valve, and the second outlet pipe A249 is equipped with a fourth check valve; the first outlet pipe A247 is connected to the inlet flow channel A214 of the first rotor A21, and the second outlet pipe A249 is connected to the inlet flow channel A214 of the buffer rotor A22; the first inlet pipe A246 is connected to coolant, and the second inlet pipe A248 is connected to an antistatic agent.

[0020] In this embodiment, when the actuating wheel A23 is driven to rotate by the moving detonating cord A4, the rotating shaft A241, which is coaxially connected to the actuating wheel A23, rotates synchronously, driving the actuating unit A245, which is located in the actuating housing A242, to rotate. The rotational motion is converted into reciprocating linear motion of the first piston rod A2453 in the first piston cylinder A243 and the second piston rod A2454 in the second piston cylinder A244 through the linkage mechanism. The entire actuation process is strictly synchronized with the running speed of the detonating cord A4, realizing adaptive medium supply without external power.

[0021] Furthermore, the actuation unit A245 includes a first drive block A2451, a second drive block A2452, a first piston rod A2453, and a second piston rod A2454. The first drive block A2451 and the second drive block A2452 are misaligned. The first piston rod A2453 is slidably connected in a sealed manner within the first piston cylinder A243. A first connecting rod A2455 is hinged to the first piston rod A2453 and is hinged to the first drive block A2451. The second piston rod A2454 is slidably connected in a sealed manner within the second piston cylinder A244. A second connecting rod A2456 is hinged to the second piston rod A2454 and is hinged to the second drive block A2452. One end of the rotating shaft A241 passes through the actuation housing A242 and is connected to the first drive block A2451.

[0022] The continuous rotation of the actuator wheel A23 is converted into alternating reciprocating motion of two piston rods (first piston rod A2453 and second piston rod A2454) with a phase difference of degrees, thereby achieving stable and continuous pumping of coolant and antistatic agent. The specific working process is as follows: When the detonating cord A4 pulls the actuator wheel A23 and the rotating shaft A241 fixed to it, the rotating shaft A241 directly drives the first drive block A2451 connected to it to rotate synchronously. The rotation of the second drive block A2452 is converted into linear reciprocating motion of the second piston rod A2454 within the second piston cylinder A244 via the second connecting rod A2456, initiating the pumping of the antistatic agent. Meanwhile, since the first drive block A2451 and the second drive block A2452 are connected in a staggered manner, the rotation of the second drive block A2452 will drive the first drive block A2451 to rotate through the staggered structure. However, there is a fixed phase difference between their movements. This phase difference ensures that when the first drive block A2451 drives the first piston rod A2453 through the first connecting rod A2455, the stroke of the first piston rod A2454 is exactly staggered with the stroke of the second piston rod A2454. This design ensures that when one piston rod is in the compression stroke (forward pumping of medium), the other piston rod is in the suction stroke (suction of medium).

[0023] In a preferred embodiment, the device further includes a second rotating wheel A5 and a third rotating wheel A6. A second sliding seat A71 is mounted on the bottom of the second rotating wheel A5. A telescopic elastic element A72 is provided between the second sliding seat A71 and the frame A1. The third rotating wheel A6 is rotatably mounted on the frame A1. The second rotating wheel A5 is located between the actuating wheel A23 and the third rotating wheel A6. The telescopic elastic element A72 has a tendency to drive the second rotating wheel A5 away from the third rotating wheel A6. The telescopic elastic element A72 includes a telescopic cylinder A721, a telescopic column A722, and a slip ring A723. The slip ring A723 is slidably connected inside the telescopic cylinder A721. The telescopic column A722 is fixedly connected to the slip ring A723, and one end of the telescopic column A722 extends out of the telescopic cylinder A721 and is fixedly connected to the second sliding seat A71. The telescopic cylinder A721 is fixedly installed on the frame A1. A spring A724 is provided inside the telescopic cylinder A721. The spring A724 has a tendency to drive the telescopic column A722 to extend outward.

[0024] After the detonating cord A4 is led out from the actuating wheel A23, it passes around the movable second wheel A5 and finally guides to the fixed third wheel A6. Under normal conveying tension, the second sliding seat A71 installed at the bottom of the second wheel A5 is pushed by the spring A724 in the lower telescopic elastic member A72. This push is transmitted through the telescopic column A722, so that the second wheel A5 always maintains a tendency to move away from the third wheel A6, thereby applying a constant and flexible tension to the detonating cord A4, ensuring reliable contact between the detonating cord A4 and each wheel without slack. When slight fluctuations in external traction speed or drum release speed cause an increase in path tension, the increased tension overcomes the preload of spring A724, forcing the second wheel A5, along with the second sliding seat A71, to move toward the third wheel A6. At this time, the telescopic column A722 retracts into the telescopic drum A721, compressing spring A724 and causing the sealing slip ring A723 to slide inside the drum. This process absorbs and buffers the instantaneous peak of tension. Conversely, when the tension decreases, the compressed spring A724 quickly releases its stored energy, pushing the telescopic column A722 and the second wheel A5 to reset, re-tightening the detonating cord A4. As a mechanical damper, the floating of the second wheel A5 compensates for minute changes in length and tension fluctuations in real time, ensuring that the detonating cord A4 maintains a stable and uniform tension state throughout the entire conveying path, especially before entering the subsequent processing or winding stage. This effectively prevents slippage, accumulation, or increased wear caused by sudden changes in tension.

[0025] In one embodiment, the third rotating wheel A6 is also a friction wheel. A first air inlet pipe A725 and a first air outlet pipe A726 are connected to the telescopic cylinder A721. A fifth one-way valve is installed at the first air inlet pipe A725, and a sixth one-way valve is installed at the first air outlet pipe A726. The first air outlet pipe A726 is connected to the third rotating wheel A6. When the tension fluctuation of the detonating cord A4 drives the second rotating wheel A5 and its bottom second sliding seat A71 to move, the telescopic column A722, which is fixed to the sliding seat, will synchronously drive the sealing slip ring A723 to slide back and forth within the telescopic cylinder A721. This process creates a sealed air chamber with periodically changing volume inside the telescopic cylinder A721. Specifically, when the tension of the detonating cord A4 increases and the second wheel A5 is forced to move towards the third wheel A6, the telescopic column A722 retracts inward, pushing the slip ring A723 to compress the air chamber. The air pressure inside the chamber increases, and at this time, the fifth one-way valve (check valve) on the first air inlet pipe A725 closes under the pressure difference, while the sixth one-way valve on the first air outlet pipe A726 opens. Compressed air is then pumped out through the first air outlet pipe A726 and delivered to the interior of the third wheel A6. Conversely, when the tension decreases and the spring A724 pushes the second wheel A5 back to its original position, the telescopic column A722 extends outward, increasing the volume of the air chamber and creating negative pressure. At this time, the sixth one-way valve closes to prevent backflow, while the fifth one-way valve opens, drawing in air from the outside to replenish the air chamber. Thus, each floating cycle of the second wheel A5 with changes in tension drives this built-in air pump to complete one intake and exhaust process. The pumped compressed air is introduced into the third rotor A6 through the first exhaust pipe A726 and blown out from the micropores on the surface of the third rotor A6, directly acting on the surface of the detonating cord A4 that is passing through the third rotor A6. This synchronously generated airflow effectively removes any excess droplets that may have remained on the detonating cord A4 during the previous cooling and coating process, achieving contact-based air cooling and cleaning. This not only further reduces the risk of frictional overheating and keeps the surface of the detonating cord A4 dry and clean, ensuring the reliability of subsequent processes (such as connecting the explosive cartridges), but more importantly, the power required for cleaning comes entirely from the mechanical motion inherent in the system itself, which is used to buffer tension, requiring no additional energy or control.

[0026] In a preferred embodiment, the first sliding seat A25 includes a sliding plate A251, a sliding rod A252, and a tension spring A253. The buffer wheel A22 rotates and is mounted on the sliding plate A251. The sliding rod A252 is slidably mounted on the frame A1, with one end of the sliding rod A252 connected to the sliding plate A251 and the other end of the sliding rod A252 connected to a rotating ring A323. One end of the tension spring A253 is connected to the frame A1, and the other end of the tension spring A253 is connected to the sliding plate A251.

[0027] The reel assembly A3 includes a mounting bracket A31 and a storage assembly A32, the storage assembly A32 being rotatably mounted on the mounting bracket A31. The storage assembly A32 includes a first shaft A321 rotatably connected to the mounting bracket A31 and a second shaft A322 coaxially disposed with respect to the first shaft A321. The second shaft A322 is configured to be axially displaced relative to the first shaft A321 along the axial direction of the first shaft A321. The second shaft A322 is rotatably connected to a rotating ring A323. A plurality of radially movable spacers are provided between the first shaft A321 and the second shaft A322. The expansion unit A8 is deformable. One end of the expansion unit A8 is connected to the first shaft A321, and the other end of the expansion unit A8 is connected to the second shaft A322. In response to the relative axial displacement between the first shaft A321 and the second shaft A322 approaching, the expansion unit A8 is forced to undergo radial expansion deformation, resulting in an increase in the outer diameter of the expansion unit A8. In response to the relative axial displacement between the first shaft A321 and the second shaft A322 moving away, the expansion unit A8 is forced to undergo radial contraction deformation, resulting in a decrease in the outer diameter of the expansion unit A8.

[0028] Furthermore, the extension unit A8 includes a take-up block A81, a first hinge rod A82 and a second hinge rod A83 arranged intersecting each other, a first mounting block A84 and a second mounting block A85 are provided on the take-up block A81, a first sliding groove A86 is provided on the first mounting block A84, and a first sliding pin A87 is slidably arranged in the first sliding groove A86. One end of the first hinge rod A82 is hinged to the second mounting block A85. A third mounting block A89 is fixedly installed on the second shaft A322. A second sliding groove A90 is opened in the third mounting block A89. A second sliding pin A91 is slidably installed in the second sliding groove A90 and is connected to the first hinge rod A82. A fourth mounting block A92 is fixedly installed on the first shaft A321. One end of the second hinge rod A83 is hinged to the fourth mounting block A92, and the other end of the second hinge rod A83 is connected to the first sliding pin A87.

[0029] During normal delivery of the detonating cord A4, the first sliding seat A25, equipped with the buffer wheel A22, remains stationary under the constant tension of the tension spring A253. The rotating ring A323 at the end of the sliding rod A252 limits the second shaft A322 of the drum assembly A3 to a specific position, causing several extension units A8 connected to the first shaft A321 to be in an expanded state. At this time, the first hinge rod A82 and the second hinge rod A83, which are cross-hinged, form a large angle, pushing the winding block A81 to extend outward. The drum thus maintains its maximum outer diameter to carry the detonating cord. A4; When the drum jams, causing an abnormal increase in the tension of the detonating cord A4, the overload force acting on the buffer wheel A22 will immediately overcome the preload of the tension spring A253, driving the entire sliding plate A251 along with the sliding rod A252 to slide along the frame A1 towards the first wheel A21. This linear displacement is converted into an axial force on the second shaft A322 without delay through the rotating ring A323, forcing the second shaft A322 to move away from the first shaft A321 along its axis; The increase in the relative distance between the two shafts forces several of the extension units A8 to... The configuration undergoes a forced change. As the third mounting block A89 on the second shaft A322 moves away from the fourth mounting block A92 on the first shaft A321, the intersection point of the first hinge rod A82 and the second hinge rod A83 moves, and the included angle between them decreases rapidly, "flattening" the entire "X"-shaped linkage mechanism. During this process, the first hinge rod A82 slides within the second slide groove A90 via the connected second sliding pin A91 to adapt to the angle change. Simultaneously, the second hinge rod A83 pulls the first sliding pin A87 on the winding block A. The first groove A86 of 81 slides, converting the axial displacement into a linear contraction motion of the winding block A81 in the radial direction; all the circumferentially distributed extension units A8 contract synchronously, causing the effective winding outer diameter of the drum to decrease instantaneously; the reduction in the drum diameter means that an additional length of detonating cord A4 is "released" for the system instantaneously. This mechanically released length directly offsets the excessive stretching demand caused by the front jamming and the rear strong pull, allowing the peak tension on the detonating cord A4 to be released, thereby avoiding the risk of breakage.

[0030] The connection device between the detonating cord and the explosive cartridge includes a support frame B1, a tape winding unit B5, an explosive cartridge feeding unit B6, a binding unit B7, and a rotating drum B2 rotatably mounted on the support frame B1. The rotating drum B2 has a hollow cylindrical structure with openings at both ends for the detonating cord B4 to pass through. The tape winding unit B5 includes a first winding disc B51 eccentrically positioned on the outer periphery of the rotating drum B2. The first winding disc B51 is used to carry the tape roll B52. The rotating drum B2 has a tape inlet on its wall. B53, the working end of the tape roll B52 passes through the tape inlet B53 and enters the inside of the rotating drum B2 to wind with the detonating cord B4, forming an adhesive-coated detonating cord B41; the explosive roll feeding unit B6 includes a feeding tray B61 that rotates synchronously with the rotating drum B2, and the feeding tray B61 is provided with at least one feeding station for receiving the explosive roll B3; the binding unit B7 is located at the end of the rotating drum B2 corresponding to the direction in which the detonating cord B4 passes through, and is connected to the rotating drum B2 to rotate synchronously with the rotating drum B2.

[0031] When the rotating drum B2 rotates, it simultaneously drives the tape winding unit B5, the explosive cartridge unloading unit B6, and the binding unit B7 to move, so that the tape is wrapped around the surface of the passing detonating cord B4 to form the rubber-coated detonating cord B41. The unloading station periodically lowers the explosive cartridge B3 onto the rubber-coated detonating cord B41, and the binding unit B7 binds the explosive cartridge B3 and the rubber-coated detonating cord B41 together.

[0032] In this embodiment, the detonating cord B4 first continuously enters from one end of the rotating drum B2 and travels along the hollow cylindrical structure with openings at both ends. Simultaneously, the drive motor B11 drives the rotating drum B2 to rotate continuously on the support frame B1. The rotation of the rotating drum B2 serves as a single power source, simultaneously driving three functional units: First, the first winding disc B51, eccentrically mounted on the outer periphery of the rotating drum B2 in the tape winding unit B55, rotates accordingly. The working end of the tape roll B52 (a viscous hot-melt pressure-sensitive adhesive tape) carried by the first winding disc B51 is continuously introduced into the rotating drum B2 through the tape inlet B53 on the drum wall, and is tightly wound in a spiral wrapping manner around the continuously traveling detonating cord B4 inside the rotating drum B2, forming an adhesive-coated detonating cord B41 with a continuous adhesive layer on its surface; Second, the explosive roll unloading unit B6, along with the rotating drum B11... 2. The synchronously rotating feeding tray B61 rotates accordingly, and multiple feeding stations evenly distributed on the circumference pass through the preset feeding positions in sequence. When the station carrying the explosive cartridge B3 moves to the feeding gap B63, the bottom baffle B64 automatically opens under the action of gravity, periodically dropping the explosive cartridge B3 onto the rubber-coated detonating cord B41 below that has been wrapped with tape. Thirdly, the binding unit B7 set at the end of the rotating drum B2 also rotates synchronously with the rotating drum B2. The eccentrically set second winding tray B71 continuously releases the binding line. Under the synergistic action of rotational inertia and the guide structure, the explosive cartridge B3 falling onto the rubber-coated detonating cord B41 is tightly wrapped and fixed with the rubber-coated detonating cord B41, completing the final automatic binding. The whole process realizes the continuous and integrated operation of synchronous rubber coating of the detonating cord B4, timed and fixed-point feeding of the explosive cartridge B3 and automatic binding.

[0033] In a preferred embodiment, the cartridge feeding unit B6 further includes a feeding ring B62 fixedly installed on the support frame B1, a feeding tray B61 rotatably disposed in the inner cavity of the feeding ring B62, and a feeding notch B63 formed at the bottom of the feeding ring B62; the feeding tray B61 is hinged to an openable baffle B64 for each feeding station. When the feeding tray B61 rotates and the feeding station carrying the cartridge B3 moves to a position aligned with the feeding notch B63, the baffle B64 automatically opens under its own weight, so that the cartridge B3 falls onto the rubber-coated detonating cord B41 through the feeding notch B63.

[0034] In this embodiment, the feeding tray B61, driven by the rotating drum B2, rotates continuously within the inner cavity of the feeding ring B62, which is fixedly installed on the support frame B1. Multiple feeding stations evenly distributed around the circumference of the feeding tray B61 sequentially carry the cartridges B3 to be fed. When a feeding station carrying a cartridge B3 moves with the rotation of the feeding tray B61 to a position aligned with the feeding notch B63 at the bottom of the feeding ring B62, the baffle B64 hinged at the bottom of that station, having lost the support of the inner wall of the feeding ring B62, automatically flips downwards and opens around the hinge point under the combined action of the weight of the cartridge B3 and its own gravity. Thus, the cartridge B3 in that station is released through the feeding notch B63 under the influence of gravity. The falling cartridge B3 then falls into the cartridge guide mechanism B8 located below the notch, directly onto the continuously output rubber-coated detonating cord B41, completing the timed and point-based automatic feeding. The feeding tray B61 continues to rotate. After leaving the gap area, the baffle B64 re-contacts the inner wall of the feeding ring B62 and is pushed back to the closed position, preparing to receive the next cartridge B3. This cycle is repeated to achieve automatic feeding of cartridge B3 for one cycle.

[0035] In a preferred embodiment, a first driving pulley is coaxially fixed on the rotating drum B2, and a shaft B65 is coaxially fixed on the axis of the feeding tray B61. A first driven pulley is coaxially fixed on the shaft B65, and a first belt B66 is tensioned between the first driving pulley and the first driven pulley. When the rotating drum B2 rotates, the first driving pulley fixed on the rotating drum B2 rotates synchronously. Through the belt drive of the first belt B66, the rotational power is transmitted to the first driven pulley, thereby driving the shaft B65, which is coaxial with the driven pulley, and the feeding tray B61 fixed on the shaft B65 to rotate at a preset speed and direction. This belt drive mechanism constitutes a mechanical synchronization link between the rotating drum B2 and the feeding tray B61, ensuring that the rotation of the medicine roll feeding unit B6 is strictly synchronized with the rotation of the main rotating drum B2. This is a key mechanical guarantee for achieving coordinated operation of tape winding, periodic feeding of medicine rolls B3, and subsequent binding processes at a unified pace.

[0036] It should be noted that the detonating cord B4 must contact and be immediately fixed to the explosive charge B3 within the time window after a complete adhesive coating has been formed on its surface and while the adhesive layer is still in its optimal viscous flow state. If each process is driven by an independent motor, even with complex sensors and electronic control programming, it is impossible to achieve precise control. The delay in electrical signal processing, servo response error, and program cycle fluctuations under high-speed continuous operation can all lead to microscopic mismatches in the action rhythm. If this mismatch accumulates to a certain extent, it can cause the explosive charge B3 to be placed at an off-center position or not securely tied. In severe cases, it can cause the seal to fail due to insufficient tape winding or the adhesive layer having hardened, or even cause equipment jamming due to action interference. This invention, driven by a single rotating drum B2 and through a pure mechanical linkage formed by the pulley transmission ratio, ensures that the phase of each dropping station of the unloading tray B61 reaching the notch position and the phase of the second winding tray B71 releasing the binding line are established between the rotating drum B2 rotating to a specific angle (i.e., the moment when the detonating cord B4 is coated with adhesive and delivered to the correct position) and the phase of the second winding tray B71 releasing the binding line. This "hard-connection" synchronization mechanism not only eliminates the inherent instability of the electronic control system and ensures the absolute timing consistency of the three major processes under any production cycle, but more importantly, it makes the contact between the explosive charge B3 and the rubber-coated detonating cord B41 in its optimal bonding state, as well as the subsequent immediate binding, a necessary result guaranteed by the mechanical structure itself. This ensures the reliability of the connection interface seal and the high stability of the production process at the principle level, and has outstanding substantive features and significant progress compared to the "fragmented" electronic control synchronization scheme.

[0037] In a preferred embodiment, the device further includes a cartridge guiding mechanism B8, which includes a guide block fixedly mounted on a support frame B1. The top of the guide block has an inclined guide groove B81 extending from near the feeding notch B63 towards the end of the rotating drum B2. The inclined guide groove B81 connects with the feeding notch B63 to receive the falling cartridge B3. The rubber-coated detonating cord B41 passes through the inclined guide groove B81. The extended end of the inclined guide groove B81 is located near the end of the rotating drum B2. After the falling cartridge B3 slides along the inclined guide groove B81 under the action of gravity, the end of the cartridge B3 can abut against the end of the rotating drum B2, thereby completing the pre-positioning of the contact with the rubber-coated detonating cord B41.

[0038] After the explosive charge B3 falls from the feeding notch B63, it falls directly into the inclined guide groove B81 on top of the guide block fixed to the support frame B1. The inclined guide groove B81 starts below the feeding notch B63 and extends at a certain angle towards the end of the rotating drum B2. The rubber-coated detonating cord B41 passes through the guide groove. Under its own weight, the falling explosive charge B3 automatically slides downwards along the inclined surface of the inclined guide groove B81. During the sliding process, the sidewall of the inclined guide groove B81 constrains and guides the rolling of the explosive charge B3, ensuring that it moves along a predetermined path. When the explosive charge B3 slides to the end of the extended inclined guide groove B81, its end just abuts against the end of the rotating drum B2, and the movement of the explosive charge B3 stops. At this point, with the guide groove limiting it, the explosive charge B3 is stably lying on the continuously output rubber-coated detonating cord B41, and the contact position between the two is accurate, thus completing the contact pre-positioning of the explosive charge B3 relative to the rubber-coated detonating cord B41, providing a precise initial position for the subsequent binding unit B7 to carry out reliable binding.

[0039] In a preferred embodiment, the binding unit B7 includes a second winding disc B71 eccentrically disposed on the outer periphery of the rotating drum B2. The second winding disc B71 is used to carry the winding coil B72. When the rotating drum B2 rotates, it drives the winding coil B72 to release the wire to wind and bind the explosive charge B3 and the rubber-coated detonating cord B41.

[0040] The second winding reel B71 is eccentrically positioned around the outer periphery of the rotating drum B2 and rotates synchronously with it. The winding coil B72 carried by the second winding reel B71 continuously releases the winding thread as it rotates. When the pre-positioned explosive cartridge B3 passes the end of the rotating drum B2 along with the rubber-coated detonating cord B41, the continuous rotation of the rotating drum B2 drives the second winding reel B71 to revolve. Due to the eccentricity between the second winding reel B71 and the rotating drum B2, its revolve trajectory allows the released binding thread to wrap around the contact point between the pre-positioned explosive cartridge B3 and the rubber-coated detonating cord B41. The binding unit B7 is driven entirely by the single rotating shaft of the rotating drum B2, requiring no additional motor or complex electrical control system. The rotation of the rotating drum B2 synchronously coordinates the three major actions: tape winding, explosive cartridge B3 unloading, and binding thread release. This ensures that the explosive cartridge B3 immediately enters the binding station after completing the contact pre-positioning, and the binding thread is wound under mechanical synchronous drive. This purely mechanical linkage fundamentally eliminates the risk of accumulated timing errors in multi-motor electronic control synchronization, ensuring that the rhythm of the three major processes of winding, unloading, and bundling is strictly unified and the actions are seamlessly connected under high-speed continuous production. It achieves truly smooth, stable, and highly reliable fully automated production, significantly improving the consistency of production efficiency and connection quality.

[0041] In a preferred embodiment, a drive motor B11 is provided on the support frame B1. The drive motor B11 is fixedly mounted on the support frame B1. The output shaft of the drive motor B11 is connected to a second drive pulley B12. A second driven pulley B13 is coaxially fixedly mounted on the rotating drum B2. A second belt B14 is tensioned between the second drive pulley B12 and the second driven pulley B13. When the drive motor B11 is started, the second drive pulley B12 on the output shaft of the drive motor B11 transmits power to the second driven pulley B13 coaxially fixedly mounted on the rotating drum B2 through the tensioned second belt B14, thereby driving the rotating drum B2 to rotate stably at a preset speed. A guide roller B15 is provided near the tape inlet B53 on the rotating drum B2. The purpose of the guide roller B15 is to comb and guide the tape drawn from the first winding disc B51, ensuring that the tape enters the tape inlet B53 flat and without twisting, effectively preventing the tape from rubbing, folding or wearing against the drum wall due to positional deviation when entering the narrow tape inlet B53.

[0042] In a preferred embodiment, the tape winding unit B5 further includes a heat activation device disposed at the first winding reel B51. The heat activation device adopts a prior art structure and is used to heat the tape before it enters the drum B2. The heat activation device (such as a heating roller or hot air gun) disposed at the first winding reel B51 uniformly heats the surface of the tape before it enters the tape inlet B53 of the drum B2, activating the hot melt pressure-sensitive tape to a viscous flow state. At the same time, the heated tape, guided by the guide roller B15, smoothly enters the interior of the drum B2 and fully fills the micro-grooves on the surface of the detonating cord B4 during the winding process due to its viscous flow characteristics. The entire system uses the drive motor B11 as the sole power source and distributes power to the drum B2, the feeding reel B61, and the binding unit B7 through mechanical transmission and synchronization mechanisms. It also integrates heat activation and guide wire sorting functions, realizing a fully integrated, highly reliable, and continuous operation from tape pretreatment, detonating cord B4 coating, explosive roll B3 feeding and positioning to automatic binding. This invention has high application value.

Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.

The continuous winding and integrated connection system of detonating cord and explosive charge according to claim 9, characterized in that: The binding unit (B7) includes a second winding disc (B71) eccentrically disposed on the outer periphery of the rotating drum (B2). The second winding disc (B71) is used to carry the winding coil (B72). When the rotating drum (B2) rotates, it drives the winding coil (B72) to unwind and bind the explosive cartridge (B3) and the rubber-coated detonating cord (B41). A drive motor (B11) is disposed on the support frame (B1). The output shaft of the drive motor (B11) is connected to a second driving pulley (B12). A second driven pulley (B13) is coaxially fixed on the rotating drum (B2). A second belt (B14) is tensioned between the second driving pulley (B12) and the second driven pulley (B13). A guide roller (B15) is disposed on the rotating drum (B2) near the belt inlet (B53).
