Description

Technical Field

[0001] This utility model relates to an auxiliary packing mechanism for emulsion explosives, specifically an automatic packing mechanism for cooled emulsion explosives. Background Technology

[0002] After being extruded, emulsion explosives are packaged in long strips using bags. After being water-cooled and air-dried, the emulsion explosives need to be boxed. In the past, boxing was mainly done manually. However, since the processing site for emulsion explosives is relatively dangerous, using a large number of manual laborers for processing poses a significant risk. Modern emulsion explosive processing needs to avoid manual labor to ensure production safety. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model proposes an automatic packing mechanism for cooled emulsion explosives, which facilitates automated packing of emulsion explosives, thus avoiding manual operation, ensuring production safety, and improving packing efficiency.

[0004] To achieve the above objectives, the present invention provides an automatic boxing mechanism for cooled emulsion explosives, comprising a box conveyor belt, an explosive gripping assembly, a temporary storage assembly, and an explosive guiding mechanism. The explosive gripping assembly is located above the end of the explosive guiding mechanism, and the temporary storage assembly is located on one side of the end of the explosive guiding mechanism. The explosive gripping mechanism moves and rises above the temporary storage assembly and the explosive guiding mechanism. A box conveyor belt is located below the temporary storage assembly, and an open box is placed on the main box conveyor belt.

[0005] A baffle is provided at the end of the explosive guiding mechanism. The explosive guiding mechanism is composed of multiple guide rods arranged side by side. A cartridge of emulsion explosive is placed between two adjacent guide rods. A conveying assembly is provided above the guide rods. Multiple clearance notches are opened at the top of the end of each guide rod. The clearance notches are for the explosive gripping assembly to grip. A support plate is provided on the explosive gripping assembly. The support plate extends into the notch to lift the explosive, so that the explosive is separated from the guide rod.

[0006] A discharge port is provided at the bottom of the temporary storage component, which allows the emulsion explosives temporarily stored in the temporary storage component to be placed into the box.

[0007] Preferably, the explosive gripping assembly includes gripping arms, a pressure plate, and a mounting base. Gripping arms are provided on the lower sides of both sides of the mounting base, and the tops of the gripping arms are slidably connected to the mounting base. A clamping cylinder is provided between the tops of the two gripping arms and the mounting base. Multiple side-by-side support plates are installed on the bottom plate of each gripping arm. A pressure plate is provided between the two gripping arms. A vertically arranged lifting rod is fixed on the top of the pressure plate. The lifting rod passes through the mounting base and moves up and down along the mounting base. A spring is sleeved on the lifting rod between the top of the pressure plate and the bottom of the mounting base. A lifting assembly is provided on the top of the mounting plate, and a translation assembly is provided above the lifting assembly. The translation assembly enables the support plates to move above the temporary storage assembly and the guide rod.

[0008] Preferably, the temporary storage assembly includes a bottom frame, a enclosure, and sliding support plates. The bottom frame is a rectangular frame, with a cavity in the middle serving as a discharge port. An upwardly extending enclosure is fixed to the top of the bottom frame, with vertical slots for the pallet to pass through. Two sets of sliding support plates are installed at the bottom of the discharge port, supporting the emulsion explosive. A waist-shaped hole is provided in the bottom frame, into which the two ends of the sliding support plates slide. A traction assembly is installed between the bottom frame and the sliding support plates, moving the sliding support plates to make way for the discharge port and discharging the material. Inverted L-shaped plates are fixed to both sides of the enclosure, with lifting cylinders installed between the inverted L-shaped plates and the ground.

[0009] Preferably, the traction assembly includes a pull rope and a traction cylinder. One end of the pull rope is connected to the sliding support plate. The pull rope contacts the outer wall of the enclosure and extends upward. A traction cylinder is fixed at the top of the enclosure. The pull rope is connected to the traction cylinder. A spring is inserted into the sliding support plate and the waist-shaped hole. The spring pushes the sliding support plate towards the middle.

[0010] Preferably, the box conveyor belt is installed on the ground, and partitions are installed on the bags of the box conveyor belt. The two partitions clamp the outer wall of the box. When the box and the temporary storage component are facing each other, the temporary storage component extends into the box for packing.

[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] like Figure 1-6 The aforementioned automatic boxing mechanism for cooled emulsion explosives includes a box conveyor belt 1, an explosive gripping assembly 3, a temporary storage assembly 12, and an explosive guiding mechanism 23. The explosive guiding mechanism 23 is arranged longitudinally, and the explosives are placed side by side on the explosive guiding mechanism 23. The explosive gripping assembly 3 is located above the end of the explosive guiding mechanism 23, and the temporary storage assembly 12, which can be raised and lowered, is located on the ground on one side of the end of the explosive guiding mechanism 23. The explosive gripping mechanism moves above the temporary storage assembly 12 and the explosive guiding mechanism 23. The explosives are lifted and lowered, and the explosives arranged side by side at the end of the explosives guide mechanism 23 are gripped by the explosives gripping mechanism. The explosives gripping mechanism rises and moves to the left above the temporary storage component 12. The explosives gripping mechanism then descends and extends into the temporary storage component 12, so that the emulsion explosives are transferred into the temporary storage component 12. A horizontally arranged box conveyor belt 1 is set on the ground below the temporary storage component 12. Boxes with openings are placed on the main box conveyor belt 1. After multiple layers of emulsion explosives are stacked in the temporary storage component 12, they are unloaded into the box for packing.

[0021] A baffle 24 is fixed to the end of the explosive guiding mechanism 23 by bolts. When the emulsion explosive conveyor belt reaches the end of the explosive guiding mechanism 23, it is stopped, thus making the end of the emulsion explosive flush. The explosive guiding mechanism 23 is composed of multiple guide rods 25 arranged side by side. A cylindrical emulsion explosive is placed between two adjacent guide rods 25. A conveying assembly 26 is set above the guide rods 25 (smooth guide rods 25). The conveying assembly 26 is a roller driven by a motor. The roller presses on the top of the emulsion explosive and conveys the emulsion explosive backward by rotating the roller. Four clearance notches 27 are opened at the top of the end of each guide rod 25. The clearance notches 27 are used for the explosive clamping assembly 3 to clamp. A support plate 4 is fixed to the explosive clamping assembly 3 by bolts. The support plate 4 extends from the left and right sides of the explosive guiding mechanism 23 into the notches to lift the explosive, thus separating the explosive from the guide rod 25.

[0022] A discharge port 13 is provided at the bottom of the temporary storage component 12. The discharge port 13 of the temporary storage component 12 is used to place the emulsion explosives that are temporarily stored into the box.

[0023] The explosive gripping assembly 3 includes gripping arms 5, pressure plates 6, and mounting bases 8. Gripping arms 5 are located on the lower left and right sides of the mounting base 8, with their tops slidably connected to the mounting base 8. A sliding groove is fixed to the ground of the mounting plate, and the tops of the gripping arms 5 slide within the groove. A clamping cylinder 9 is bolted between the top of each gripping arm 5 and the mounting base 8, allowing the two gripping arms 5 to close and separate. Multiple parallel clamping plates are bolted to the base plate of each gripping arm 5. The pallet 4 is equipped with a pressure plate 6 between two clamping arms 5. A vertically mounted lifting rod 7 is fixed to the top of the pressure plate 6 by bolts. The lifting rod 7 moves up and down along the mounting base 8, thus raising and lowering the pressure plate 6. A spring is fitted on the lifting rod 7 between the top of the pressure plate 6 and the bottom of the mounting base 8. The spring presses the pressure plate 6 downward, thus pressing the emulsion explosive on the pallet 4 and preventing it from rolling on the pallet 4 during transportation. The plate 4 falls down; a lifting assembly 10 is installed on the top of the mounting plate, which is a cylinder. The cylinder body is installed on the translation plate by bolts. The bottom of the lifting assembly 10 is installed on the top of the mounting base 8 by bolts. The lifting assembly 10 is used to lift and lower the mounting base 8. A translation assembly 11 is installed above the lifting assembly 10, which is a translation plate. A gantry frame is fixed on the ground by bolts. A long opening is opened at the top of the gantry frame for the translation plate to be inserted. The slide plate slides left and right within the long slot. A lead screw driven by a motor is installed on the top of the gantry via bearings. A slide sleeve is fixed on the top of the slide plate by bolts. The slide sleeve is fitted onto the lead screw and the slide sleeve is threaded with the lead screw. The slide plate moves by rotating the lead screw. The slide assembly 11 moves the support plate 4 above the temporary storage assembly 12 and the guide rod 25. In this way, the emulsion explosive is transferred from the explosive guiding mechanism 23 to the temporary storage assembly 12 via the support plate 4.

[0024] The temporary storage assembly 12 includes a bottom frame 14, a enclosure 15, and a sliding support plate 17. The bottom frame 14 is a rectangular frame, and the cavity in the middle of the bottom frame 14 is a rectangular discharge port 13. A rectangular enclosure 15 extending upwards is fixed to the top of the bottom frame 14 by welding. Four vertical slots 16 are opened on the left and right sides of the enclosure 15, through which the pallet 4 passes. During loading, the pallet 4 moves to the top of the temporary storage assembly 12 and descends. The pallet 4 descends along the slots 16. When the bottom of the pallet 4 is pressed (a pressure sensor is embedded in the bottom of one of the pallets 4, which is triggered when pressed), the pallet 4 is released from pressure. When the lifting assembly 10 stops descending, the pallet 4 stops descending and moves to both sides and opens via the clamping arms 5, thus separating the emulsion explosive from the pallet 4 and allowing it to fall into the temporary storage assembly 12. Two sets of sliding support plates 17 are provided at the bottom of the discharge port 13, supporting the emulsion explosive. Two sets of oblong holes are provided on the bottom frame 14, extending into the oblong holes at both ends of the sliding support plates 17. When the sliding support plates 17 move towards the center, they support the emulsion explosive, thus keeping it within the temporary storage assembly 12. When multiple layers of emulsion explosive are stacked, unloading is required. When the sliding support plate 17 moves to the left and right to make way for the unloading port 13, the emulsion explosive in the temporary storage component 12 is unloaded into the box. A traction component 18 is provided between the bottom frame 14 and the sliding support plate 17. The traction component 18 moves the sliding support plate 17 to make way for the unloading port 13, and the unloading is carried out by the traction component 18. Inverted L-shaped plates 21 are fixed to the front and rear sides of the enclosure 15 by bolts. Lifting cylinders 22 are fixed to the inverted L-shaped plates 21 and the ground by bolts. The temporary storage is realized by the electric lifting push rod. The temporary storage component 12 is raised and lowered. During operation, emulsion explosives are stacked layer by layer in the temporary storage component 12 through the pallet 4. After stacking multiple layers, the temporary storage component 12 needs to be unloaded. In this way, the electric lifting push rod retracts, and the temporary storage component 12 descends into the box. Then, the traction component 18 pulls the sliding support plate 17 to move to the left and right sides. Then, the lifting cylinder 22 lifts, and the temporary storage component 12 rises. The emulsion explosives in the temporary storage component 12 remain in the box due to the discharge port 13. When the temporary storage component 12 rises and resets, the traction component 18 returns to its original position and moves back to the center through the sliding support plate 17, so that the stacking of emulsion explosives can continue.

[0025] The traction assembly 18 includes a pull rope 19 and a traction cylinder 20. One end of the pull rope 19 passes through the enclosure 15 and is connected to the sliding support plate 17 by a rope. The pull rope 19 contacts the outer wall of the enclosure 15 and extends upward. The traction cylinder 20 is embedded and fixed at the top of the enclosure 15. The pull rope 19 is connected to the piston rod of the traction cylinder 20 by a rope. When the traction cylinder 20 is lifted, the pull rope 19 pulls the sliding support rod to move outward, thus unloading the emulsion explosive. A spring is installed in the sliding support plate 17 and the waist-shaped hole. The spring pushes the sliding support plate 17 towards the middle. That is, when the traction is lost, the spring moves the sliding support plate 17 towards the middle to support the emulsion explosive.

[0026] The box conveyor belt 1 is installed on the ground. Multiple rollers are installed on the ground through bearings and bearing seats. One of the rollers is fixed to the output shaft of the motor by welding. The box conveyor belt 1 is fitted on the roller and the box conveyor belt 1 is used to transport the box. Multiple equally spaced partitions 2 are installed on the bag of the box conveyor belt 1 by bolts. Two partitions 2 clamp the outer wall of the box. When the box and the temporary storage component 12 are vertically aligned, the temporary storage component 12 extends into the box for packing. When the temporary storage component 12 descends, the box conveyor belt 1 stops transporting. When the temporary storage component 12 rises back to its original position, the box conveyor belt 1 resumes transporting.

[0027] To achieve automated packing, a PLC controller is required. Both the motors driving the conveyor assembly 26 and the lead screw are stepper motors. These stepper motors are connected to the PLC controller via encoders. The PLC controller controls the two stepper motors to drive the conveyor assembly 26 and the lead screw. When the lead screw drives the translation plate to move to the left, the stepper motors driving the conveyor assembly 26 rotate the assembly to convey the emulsion explosive backward. When the stepper motor controlling the lead screw stops rotating, the conveyor assembly 26 stops working. (The conveyor assembly 26 operates while the translation plate moves to the left.) During the conveying process, when the translation plate moves to the right and is above the temporary storage component 12, the conveying component 26 conveys the emulsion explosive to the end (where it contacts the baffle 24). When the drive screw rotates, the number of rotations of the screw is limited. When the translation plate is directly above the temporary storage component 12, the stepper motor stops working. After the emulsion explosive is unloaded from the temporary storage component 12, the stepper motor that drives the screw rotates reverses, controlling the number of rotations of the screw. In this way, the translation plate moves directly above the explosive guide mechanism 23. The clamping cylinder 9, lifting component 10, lifting cylinder 22, and traction cylinder 20 are connected to the air compressor through pipelines. A solenoid valve is fixed to the pipeline via a threaded joint. The solenoid valve is connected to the PLC. When the translation plate is above the explosive guide mechanism 23, the lifting assembly 10 rises and falls, and the clamping cylinder 9 retracts. This allows the support plate 4 to extend into the notch of the guide rod 25. Then, the lifting assembly 10 retracts and rises, and the translation plate moves to the left above the temporary storage assembly 12. The lifting assembly 10 rises and falls into the temporary storage assembly 12, and then the clamping cylinder 9 rises. The support plate 4 moves to the left and right and opens, allowing the emulsion explosive to fall into the temporary storage assembly 12. When multiple layers of emulsion explosive are stacked in the temporary storage assembly 12... The lifting cylinder 22 retracts, and the temporary storage component 12 descends and extends into the box. When the bottom of the temporary storage component 12 contacts the bottom of the box, the traction cylinder 20 lifts, the sliding support plate 17 makes way for the discharge port 13, and then the lifting cylinder 22 lifts, the temporary storage component 12 rises, and the emulsion explosive falls into the box. While the lifting cylinder 22 is working, the box conveyor belt 1 stops conveying. The pressure sensor is LL-080 and is connected to the PLC. When the pressure sensor detects pressure, the lifting component 10 stops lifting, which facilitates the stacking of the emulsion explosive by the temporary storage component 12.
