[0020] The processing method of porous granular ammonium nitrate oil explosive is as follows:

[0021] S1: The user pours the raw materials into the cylinder through the feeding port. The device system controls the servo motor to start. The output shaft of the servo motor will drive the transmission gear ring and the outer cylinder to rotate through the gear. At this time, the outer cylinder will drive the mixing mechanism to rotate. The mixing plate inside the mixing mechanism will further mix the raw materials. During this process, the outer cylinder will drive the support column to rotate synchronously through the transmission member. The support column will drive the rotating disk connected to the bottom to rotate synchronously. The telescopic teeth fixed on the outer edge of the rotating disk will rotate synchronously around the outer gear ring, thus starting the mixing operation;

[0022] S2: During the above process, the power gear installed on the top of the support column will rotate synchronously, and the power gear will drive the force gear to rotate intermittently. At this time, the force gear will drive the casing to rotate synchronously, so that the casing moves on the threaded shell. The casing will drive the pressure rod to move downward synchronously through the insertion rod, so that the pressure rod can press against the transmission member. The transmission member drives the push rod to move downward along the inner wall of the support column to compress the reset spring. When the support column rotates a certain number of times, the transmission member will move to the circular storage cavity at the bottom of the outer cylinder, thereby releasing the transmission relationship. At this time, the explosive raw materials in the cylinder will be mixed;

[0023] S3: Following the above steps, when the support column stops rotating, the rotating disk and the baffle will stop rotating synchronously, and the device system controls the conveying assembly to transport the explosive packaging bag to the bottom of the discharge port of the discharge base. At this time, the servo motor will drive the mixing mechanism to rotate a certain number of circles to perform the unloading operation. During this process, the outer cylinder will drive the connecting arm to rotate synchronously, and the connecting arm will drive the discharge tray installed at the bottom to rotate synchronously. The explosive products in the cylinder will gather in the trough of the discharge tray. At this time, the discharge tray will drive a certain amount of products in the trough into the bottom of the baffle. When the discharge tray rotates to a certain When the angle is set, the trough will coincide with the discharge port below the baffle. At this time, the product in the trough will fall into the discharge base through the discharge port, and the raw materials in the discharge base will fall into the storage packaging bag below. When the servo motor rotates a certain number of circles, the feeding is completed, the glue spraying component is connected to the external glue supply equipment, and then the device system will control the conveying component to run for a certain time. At this time, the packaging bag containing the product will pass through the glue spraying component. During this process, the device system controls the glue spraying component to start synchronously, and the glue liquid is atomized and sprayed onto both sides of the bag opening through the two nozzles of the glue spraying component.

[0024] S4: Then, the conveying assembly will drive the packaging bag containing the product to move toward the sealing piece. During this process, the pressure block on the conveying assembly will contact the force plate on the push plate and apply pressure. At this time, the two push plates will move along the guide groove at the bottom of the loading beam, and the push plate will stretch the movable end of the elastic telescopic rod. The push plate drives the corresponding storage cylinder to move. During this process, the sealing piece inside the storage cylinder will be pressed toward one side of the packaging bag, so that the two sealing pieces can be pressed against one side of the bag opening to achieve glue sealing. The push plate continues to move a certain distance. At this time, the pressure spring between the storage cylinder and the sealing piece will be compressed. During this process The push plate will drive the tooth plate to move synchronously. When the tooth plate moves to the appropriate distance, the teeth on the tooth plate can drive the gear on the control part to rotate a certain angle. The inclined rod on the top of the control part will drive the arc-shaped straw to rotate a certain angle. At this time, the straw will rotate sideways at the sealing part, so that the lower end of the straw can enter the inner side of the explosive packaging bag. Then the device system controls the drive motor and the transmission component to start and stop according to a certain time. At this time, the two drive motors will drive the corresponding rollers on the sealing part to rotate, so that the bag opening can be sealed while the packaging bag is moving. When the packaging bag is When the bag is about to be sealed, there is a straw in the gap left by the bag mouth. At this time, the device system controls the air pump to start, and the air pump extracts the air in the packaging bag through the straw, thereby effectively reducing the residual air in the packaging bag and preventing the explosive product from getting damp. After that, the pressure block on the conveying assembly will move to the slot on the force plate close to the push plate. During this process, the movable end of the elastic telescopic rod will drive the push plate to move in the opposite direction for a certain distance through the reset action. At this time, the push plate will drive the control part to rotate a certain angle through the tooth plate to reset. The straw is removed from the packaging bag, and at the same time, the push plate will drive the storage cylinder to move a certain distance synchronously. The cam is then released, and the pressure block is separated from the push plate and no longer applies pressure. At this time, the movable end of the elastic telescopic rod drives the push plate to completely return to its original position. At this time, the push plate drives the tooth plate and the sealing member to move synchronously to return to their original position. According to the above steps, the unloading operation is carried out.

[0025] S5: After the explosive product in the cylinder is released, the device system controls the driving electric cylinder on the insertion rod to start, so that the end of the insertion rod can be disengaged from the top hole of the pressure rod to release the limit. When the outer cylinder rotates a certain number of circles, the transmission part will coincide with the mounting groove on the outer cylinder. At this time, the reset spring will push the transmission part upward and re-enter the slot on the outer cylinder. From the above steps, it can be seen that the reverse rotating outer cylinder can drive the support column to rotate synchronously, so that the casing can be reset, and the top of the pressure rod will be restored to its original position synchronously. Then the device system controls the electric cylinder on the insertion rod to start again, so that the end of the insertion rod can re-position the top of the pressure rod.

When the stirring mechanism runs for a certain time to complete the stirring of the material, the timing conversion mechanism is triggered to automatically discharge the material. The specific contents are as follows:

The tooth surface of the forced gear is rotatably installed on the bottom of the shell through a connecting ring. The two are coaxially arranged. A coaxial sleeve is provided through the middle of the shell. The threaded groove provided on the upper part of the sleeve forms a threaded connection with the shell. A gap is left between the lower part of the sleeve and the inner wall of the shell. The protrusion on the inner wall of the forced gear is slidably embedded in the slide groove opened on the side wall of the sleeve to form a transmission structure. A pressure rod is slidably installed at the axis of the sleeve. The lower end of the pressure rod is located above the transmission member. The support column drives the forced gear to rotate through the power gear, so that the forced gear drives the sleeve to move on the shell. At this time, the sleeve will drive the pressure rod to move synchronously. After a certain period of time, the pressure rod will push the transmission member to move to the appropriate position to form a timing trigger structure.

[0028] 2. The annular surface of the edge of the discharge tray is provided with troughs distributed at equal angles, and corresponding baffles are provided between the troughs. The bottom surface of the baffle is fitted on the annular surface of the discharge tray, and one end of the baffle is fixedly connected to the inner wall of the rotating disk. The other end of the baffle is fitted on the conical surface in the middle of the discharge tray. The rotating disk is provided with through discharge ports distributed at equal angles. The discharge port is located between two adjacent troughs and is located directly below the middle of the corresponding baffle. When the timing structure is triggered and the rotating disk stops rotating, the discharge tray on the stirring mechanism will drive the trough to continue to rotate periodically, so that the trough can be aligned with the corresponding discharge port for quantitative discharge.
