Description

Technical Field

[0001] This invention belongs to the field of detonator manufacturing, specifically relating to an integrated production line for detonator demolding, labeling, and packaging. Background Technology

[0002] Civil explosives, as a fundamental industry, are widely used in energy extraction, water conservancy and hydropower construction, and highway and railway construction. In recent years, the production of civil explosives has been continuously increasing. Powdered and gelatinous explosives are widely used domestically, as they offer advantages such as safety and low cost, but their initiation sensitivity is relatively low. Detonators, on the other hand, can reliably detonate various industrial explosives and other insensitive explosives, achieving detonation at any location within the borehole. The enormous energy generated by the detonator's explosion provides a significant initiation energy to the corresponding industrial explosives within the borehole, allowing them to achieve stable detonation in a very short time. The high effective energy generated by the explosion results in greater damage to the adjacent medium, saving on the amount of explosives used in blasting operations, significantly reducing the proportion of large fragments obtained from blasting, and decreasing the amount of secondary blasting explosives required, bringing numerous economic and safety benefits to enterprises. Currently, most detonating explosives in my country are produced in batches by intermittent manual labor. Key processes such as removing the cap, attaching the explosive charge, and labeling the detonator involve a lot of manual operation, resulting in poor production safety, low production efficiency, and many other problems.

[0003] Chinese invention patent publication CN104833273 B discloses a fully automatic detonator removal, demolding, cleaning, and labeling integrated machine, including a frame and a detonation mechanism, a demolding mechanism, a cleaning mechanism, and a labeling mechanism arranged in parallel at the four corners of the frame. A conveying device is provided at the bottom of the detonation mechanism and the demolding mechanism. The detonator is transported to the detonation mechanism and the demolding mechanism in sequence through the conveying device for detonation and demolding. After demolding, the detonator enters the cleaning mechanism and the labeling mechanism in sequence to complete the cleaning and labeling of residual explosives.

[0004] Preferably, the cap removal mechanism includes a cap removal hydraulic cylinder, a cap removal moving cylinder, a cap pushing cylinder, a cap pushing clamp, a cap removal adjustable upper clamp, a cap removal lower clamp, and a slide rail: the cap removal hydraulic cylinder is located at the top of the cap removal mechanism, and the cap removal adjustable upper clamp is connected below it; the cap removal moving cylinder is located on the slide rail on the left side of the cap removal mechanism, and drives the cap removal hydraulic cylinder and the cap removal adjustable upper clamp to move horizontally; the cap removal lower clamp is fixedly located at the bottom of the cap removal mechanism; the cap pushing cylinder is located directly below the cap removal moving cylinder, and the cap pushing cylinder is connected to the cap pushing clamp and drives the cap pushing clamp to move.

[0005] Preferably, the mold ejection mechanism includes a mold ejection hydraulic cylinder, a mold ejection forward and backward movement cylinder, a translational robotic arm, a mold ejection up and down movement cylinder, a mold ejection robotic finger, an upper mold ejection clamp, and a lower mold ejection clamp. The mold ejection hydraulic cylinder is located at the top of the mold ejection mechanism and connected to the upper mold ejection clamp. The mold ejection forward and backward movement cylinder and the translational robotic arm are located directly below the mold ejection hydraulic cylinder. The mold ejection forward and backward movement cylinder is connected to the translational robotic arm. The mold ejection up and down movement cylinder is fixedly connected to the bottom of the translational robotic arm. The mold movement robotic finger is installed at the bottom of the mold ejection up and down movement cylinder. The upper mold ejection clamp and the lower mold ejection clamp are located at the bottom of the mold ejection mechanism and cooperate to fix the product mold.

[0006] Preferably, the cleaning mechanism includes a product clamping cylinder, a product clamping mechanism, a positioning fixture, a scraping lifting servo, a scraping translation servo, and a scraping mechanism: the product clamping cylinder is located at the rear end of the top of the cleaning mechanism and is connected to the product clamping mechanism located at the top of the cleaning mechanism; the scraping lifting servo is fixedly installed at the bottom of the cleaning mechanism and is connected to the positioning fixture above it; the scraping translation servo is located at the front end of the cleaning mechanism and is connected to the scraping mechanism.

[0008] The fully automatic detonator removal, mold removal, cleaning, and labeling machine disclosed in the above invention directly removes the detonator. The core mold is inserted through the detonator's explosive body and reaches the cap explosive. The friction between the core mold and the explosive body is relatively large. If the cap explosive is removed directly, there is adhesion between the cap explosive and the core mold. When separating the cap explosive, the cap explosive block will break and splatter, causing a significant safety hazard. It may also leave cap explosive blocks on the detonator's explosive body, which is not conducive to the next process. The mold removal and cleaning mechanisms are separate, which complicates the mold removal and cleaning mechanisms. After labeling, coding and packaging still need to be completed manually. Summary of the Invention

The top of the core mold cylinder is connected through a cylinder fixing beam located at the top of the connecting plate.

[0020] Preferably, the core-loosening mold lifting clamp is in an inverted T-shape.

[0021] Furthermore, the detonator unloading machine includes a detonator clamping assembly located between production lines.

A cap rotation motor is connected to either side of the second cap fixing plate. The bottom of the second cap fixing plate is equipped with a push rod for ejecting the cap charge and a push rod fixing frame. The top of the push rod fixing frame is also connected to a push rod lifting cylinder.

[0022] Preferably, the cap opening and the cap opening medicine receiving platform include a receiving platform top plate, a receiving platform lifting cylinder is installed at the bottom of the receiving platform top plate, and receiving platform rotating motors that can be flipped left and right are respectively provided on both sides of the receiving platform top plate.

[0023] Furthermore, the core-removing mold machine includes a core-removing mold support bracket. Core-removing mold support legs on both sides of the bottom of the core-removing mold support bracket are located on both sides of the production line. A horizontally movable core-removing mold fixing plate is provided at the top center of the core-removing mold fixing plate. A core-removing mold lifting cylinder is provided at the top center of the core-removing mold fixing plate. Baffles are provided at the bottom of both ends of the core-removing mold fixing plate. A core-removing mold cleaning lifting cylinder is installed at the bottom center of the core-removing mold fixing plate. A core-removing mold cleaning assembly is connected to the bottom of the core-removing mold cleaning lifting cylinder. A first robotic arm for holding the detonator is installed between the inner sides of the bottom of the baffles. The core-removing mold cleaning assembly is located at the top of the first robotic arm. A residue collection point is also provided on the production line after the core-removing mold is removed. The core-removing mold cleaning assembly includes a core-removing mold cleaning fixing frame. The top of the core-removing mold cleaning fixing frame is connected to the bottom of the core-removing mold cleaning lifting cylinder. A cleaning component is provided at the bottom of the core-removing mold cleaning fixing frame, and a rotary motor is provided at the top of the core-removing mold cleaning fixing frame.

[0024] Preferably, the cleaning component is a copper shovel or a copper brush.

[0025] Preferably, the first manipulator includes a clamp fixing frame, with two pairs of clamp connecting rods arranged laterally in the center of the clamp fixing frame. The clamp fixing frame is equipped with a clamp retraction cylinder that opens and closes the clamp connecting rods. Clamping plates are evenly installed between the clamp connecting rods. The clamping plates are a pair of silicone elastic clamping pieces. The contact surface between the silicone elastic clamping pieces and the detonator is concave and conforms to the outer surface of the detonator.

[0026] Furthermore, the rotary positioning mechanism includes rotary support legs located at the bottom on both sides of the production line, and a detonator placement platform located at the top of the production line. The bottom of the detonator placement platform is equipped with a lifting cylinder and a rotary motor, and the top of the detonator placement platform is equipped with a core rod for supporting the detonator.

[0027] Furthermore, the labeling mechanism includes a movable labeling fixing plate located on the top support of the production line. The labeling fixing plate is connected to the labeling assembly via a screw. A labeling cylinder that moves up and down is sleeved in the center of the labeling fixing plate. The labeling assembly includes a labeling top plate, which is connected to the screw. Slide rods that allow the slider to move left and right are respectively provided on both sides of the bottom of the labeling top plate. The bottom of the slider is connected to a downward-facing slide rail. A solenoid valve for picking up or covering labels is slidably connected to the bottom of the slide rail. A frustum for picking up or covering labels is provided at the bottom of the solenoid valve. The two sides of the solenoid valve are connected by a telescopic cylinder.

[0028] In use, the cooled detonator is transported to the core-loosening mold machine via the production line. The cap assembly is pressed down, and the core-loosening mold assembly is lifted, separating the detonator from the mold plate. After separation, the production line transports the separated detonator and mold plate together to the cap-removing machine. The detonator clamp at the bottom of the cap-removing machine holds the detonator, and the cap-removing assembly at the top of the machine fixes the cap, removes the cap, and moves the cap to the cap and cap charge receiving platform. The cap charge is removed by the push rod, and the robot releases the cap, which falls to the cap and cap charge receiving platform. After the cap is removed, the detonator and mold plate are transported to the core-removing mold machine via the production line. The detonator is then moved to the residue collection area, where the cleaning component cleans the residue on the top of the detonator. The detonator with the mold removed is transported to the cap-labeling machine via the rotating positioning mechanism for cap labeling. After cap labeling, the sides are cleaned, the detonator is bagged, boxed, instructions are added, the box is sealed, and the package is transferred to the warehouse.

[0029] After the production line modification, the designed capacity of this invention is greater than 1000 rounds / hour; the core mold is released using two 5T booster cylinders, pulling 10 pieces at a time, with a single detonator experiencing a force of 1T (fast and with low total air consumption); unloading the cap and cap charge: using rubber coating, clamping plates, and a bottom support plate to prevent the cap from falling off; reducing the dropping height, using a receiving platform to raise and receive the cap and cap charge respectively, then lowering them down so they slide into the frames on both sides; core mold removal: using rubber coating, clamping plates, and a bottom support plate to clamp ten detonators at a time; moving to the cleaning position, cleaning the residual charge residue with a rotating copper brush on top, then placing the detonator into the rotating positioning station, and pushing the fixture and core mold into the mold storage line to await manual transfer; The rotary positioning mechanism rotates the detonator to the labeling position, where a manual inspection station is located. After the label is affixed, the detonator is rotated 90° and pushed into the side cleaning conveyor line for cleaning and coding. Then, it is stacked, shaped, and bagged. Vacuuming, bagging, and boxing are performed. During boxing, the packaged detonator is pushed into the carton from the side, and then the carton is flipped 90° and flows through the roller conveyor to the instruction manual placement station. The carton opening machine opens the carton, affixes the carton label, and then flows to the packing station to wait. The carton containing the detonator is then filled with the instruction manual (fed by a collating machine), sealed, and packaged.

[0030] The core mold loosening device is included in this invention because the core mold is inserted through the detonator's explosive body and reaches the cap explosive. The friction between the core mold and the explosive body is significant. If the cap explosive is removed directly, there is adhesion between the cap explosive and the core mold. Separating the cap explosive can cause the cap explosive to break and scatter, creating a significant safety hazard. It may also leave cap explosive fragments on the detonator's explosive body, hindering subsequent processes. Loosening the core mold allows the detonator, along with the cap explosive, to be pulled out approximately 5cm. The core mold rod is already separated from the cap explosive, preventing the aforementioned problems. The cap stabilizing mechanism added at this step lowers during core mold loosening, gently pressing down on the cap to prevent it from falling off and maintaining the stability of the detonator and cap.

[0031] The cap removal process utilizes an MDBB100 cylinder for lifting, and is secured with elastic rubber-coated clips and a bottom support plate to ensure good contact between the clips and each detonator. Compared to existing technologies, this invention enables the separation of the cap and cap charge on-line. Specifically, the receiving platform is raised in stages to receive the cap and cap charge separately. After receiving, axial rotation separates them to the left and right, allowing them to fall separately on both sides. During the falling process, the receiving platform is approximately 450mm from the bottom of the box.

[0032] Compared to existing technologies, the core mold removal and top cover cleaning process combines the mold removal and cleaning steps into one, simplifying the process. It also employs a rotary cleaning mechanism, replacing the existing translational cleaning method, making it more innovative and efficient. The mold removal clamp and cleaning mechanism are fixed on the same movable bracket, eliminating the need to reposition the detonator during cleaning. This method is more stable, simpler, and more innovative than existing detonator cleaning and positioning methods. The mold removal uses a rubber-coated clamp and bottom support plate for a secure and reliable grip, capable of holding ten detonators at a time while simultaneously cleaning residual explosive residue from the top cover. The cleaning mechanism uses a rotating copper shovel or brush that can move up and down on the top of the detonator, allowing for more effective cleaning of the top cover residue through multiple rotations. After mold removal, the core mold and mold plate remain connected and are removed together from the line, pushed into the mold storage roller line for manual transfer. The mold storage line can store more than 30 molds.

[0033] After the core mold is removed and the top cover residue is cleaned, the detonator is placed directly on the rotating station to enter the labeling process. The bottom of the detonator is fixed by a pin, eliminating the need for translation cylinders, material handling robots, and product handling cylinders in existing technologies, making the operation simpler and more efficient. The labeling mechanism uses a suction cup to pick up the labeling paper from the labeling mechanism and moves it to directly above the detonator via the translation cylinder for labeling. Five labels are picked up at a time and applied in two batches, greatly increasing work efficiency. Afterward, the rotating station rotates the detonator 90° to the detonator collection station. The translation cylinder on the rotating station pushes the detonator to the collection station, where the detonators are lined up one at a time, with cleaning rollers on both sides to clean the sides of the detonators, replacing the manual operation of existing technologies.

[0067] Preferably, the number of the detonator, the core mold rod on the mold plate, and the cap top explosive rod are the same, set to ten, and the number of the detonator clamping plate and the cap fixing clamping plate are also the same, set to ten pairs.

[0068] like Figure 2As shown, in this invention, after raw material preparation, screening, conveying, melting and injecting, and dust removal and ventilation, the cooled detonator is transported to the core loosening mold machine 1 via the production line. The cap assembly is pressed down, and the core loosening mold assembly is lifted, separating the detonator from the mold plate. After separation, the production line 13 transports the separated detonator and mold plate together to the cap unloading machine 2. The detonator clamp at the bottom of the cap unloading machine 2 holds the detonator, and the cap unloading assembly at the top of the cap unloading machine 2 fixes the cap, removes the cap, and moves the cap to the cap and cap charge receiving platform 202. The cap charge is then unloaded via the push rod 207. A robotic arm 14 releases the cap and drops it onto the cap and cap charge receiving platform 202. After the cap is disassembled, the detonator and mold plate are transported to the core removal machine 3 via production line 13. The detonator is then picked up and moved to the residue collection area 309. The cleaning component cleans the residue on the top of the detonator. The detonator with the mold removed is transported to the cap labeling machine 5 via a rotating positioning mechanism for cap labeling. After cap labeling, the sides are cleaned, the detonator is bagged, boxed, instructions are placed, the box is sealed, and the detonator is transported to the warehouse. The cap charge enters the raw material accuracy area for secondary use, and the cap and mold plate are returned for secondary use.

[0069] The production line of this invention has a designed capacity of more than 1000 rounds / hour after modification; the core mold loosening machine 1 uses two 5T booster cylinders to pull 10 pieces at a time, with a single detonator loosening force of 1T (fast and low total air consumption); unloading the cap and cap charge: rubber coating, clamping plates, and bottom support plates are used to prevent the cap from falling off; the dropping height is reduced, and the receiving platform is raised to receive the cap and cap charge, and then lowered down to slide into the frames on both sides; the core mold removal machine 3: rubber coating clamping plates and bottom support plates are used to clamp ten detonators at a time; after moving to the cleaning position, the top rotating copper brush cleans the residual slag and then puts the detonator into the rotating positioning station, and the fixture and core mold are pushed into the mold storage line to wait for manual transfer; The rotary positioning mechanism rotates the detonator to the labeling position, where a manual inspection station is located. After the label is affixed, the detonator is rotated 90° and pushed into the side cleaning conveyor line for cleaning and coding. Then, it is stacked, shaped, and bagged. Vacuuming, bagging, and boxing are performed. During boxing, the packaged detonator is pushed into the carton from the side, and then the carton is flipped 90° and flows through the roller conveyor to the instruction manual placement station. The carton opening machine opens the carton, affixes the carton label, and then flows to the packing station to wait. The carton containing the detonator is then filled with the instruction manual (fed by a collating machine), sealed, and packaged.
