Description

Technical Field

[0001] The utility model relates to the technical field of powder emulsion explosive transportation, in particular to a powder emulsion explosive transportation device. Background Art

[0002] After the production of powder emulsion explosive is completed, it is quantitatively filled into woven bags by a bag packaging machine. After being sealed by a sewing mechanism, it stands upright on a conveyor belt. By means of intercepting and toppling the bag or pushing the bag with a push plate, the packaging bag is made to lie flat, and then transported to the stacking position along with the conveyor belt. To make reasonable use of the production line space, the conveyor belt also includes a turning mechanism.

[0003] Currently, independent bag pushing, turning and weighing mechanisms need to be set up on the packaging bag conveyor line to achieve corresponding functions. Among them, for flexible packaging bags, when toppling the upright bag into a lying flat state, the method of intercepting to make the packaging bag lie down will cause the packaging bag to be not neatly aligned after lying flat. When the palletizing robot grabs the packaging bag, it is easy to grab it obliquely, resulting in uneven palletizing or even toppling of the stack; when using a push plate to topple the bag, it is easy to cause extrusion, and there is a hidden danger of damage to the packaging bag; turning also needs to be achieved through a special turning mechanism; weighing also requires reserved waiting time to complete; after the bag is toppled, the materials in the packaging bag are unevenly distributed; it has the defects of complex equipment composition, large floor area, low space utilization rate, long transportation time, low production efficiency, high production line construction cost, the need for workers to always pay attention to the operation status of each mechanism and make adjustments, and high labor intensity. Summary of the Utility Model

[0004] The utility model aims to at least solve one of the technical problems in the related technologies to some extent. For this purpose, an object of the utility model is to provide a powder emulsion explosive transportation device, which realizes the integrated transportation functions of weighing, bag pushing and turning, simplifies the equipment structure, reduces the floor area, increases the space utilization rate of the production line, and saves the transportation time.

[0005] A powder emulsion explosive transportation device according to the utility model includes a bag packaging machine, a bag pushing assembly and a weighing platform. A second conveyor belt is installed at the upper end of the weighing platform. A first conveyor belt is installed between the inlet of the second conveyor belt and the outlet of the bag packaging machine. The conveying directions of the first conveyor belt and the second conveyor belt are the same. A fourth conveyor belt is provided on one side of the second conveyor belt perpendicular to the conveying direction. The conveying direction of the fourth conveyor belt is perpendicular to the conveying direction of the second conveyor belt. A bag pushing assembly is installed on the side of the second conveyor belt away from the fourth conveyor belt.

[0006] Preferably, the bag pushing assembly includes a mounting plate and a pushing pair of rollers. An installation groove is formed on one side of the mounting plate close to the second conveyor belt. A rotating shaft is rotatably installed on the upper part inside the installation groove. The pushing pair of rollers is arranged at the lower part inside the installation groove. Both ends of the pushing pair of rollers are connected to the rotating shaft through pushing pair of roller mounting rods. The pushing pair of rollers is rotatably connected to the pushing pair of roller mounting rods. A push rod is arranged between the pushing pair of rollers and the rotating shaft. The push rod is connected to the pushing pair of roller mounting rods. A cylinder installation groove is formed at the position of the installation groove corresponding to the push rod. A cylinder is installed inside the cylinder installation groove. The telescopic end of the cylinder is rotatably connected to the push rod.

[0007] Preferably, a third conveyor belt is installed between the second conveyor belt and the fourth conveyor belt. The third conveyor belt is a drum-type conveyor belt. A plurality of vibrating rods are uniformly arranged along the surface at each group of drums of the third conveyor belt.

[0008] Preferably, a photoelectric detection switch for providing control signals to the bag pushing assembly and the second conveyor belt is installed on one side of the second conveyor belt away from the first conveyor belt.

[0009] Preferably, a control cabinet with a display screen is installed on the side wall of the bag pushing assembly.

[0010] The beneficial effects of the present utility model are as follows:

[0011] (1) The functions of weighing, pushing down, and turning are completed at the second conveyor belt, which simplifies the equipment structure, reduces the floor area, increases the utilization rate of the production line space, and saves the conveying time;

[0012] (2) The bag pushing assembly is driven by a cylinder. The pushing pair of rollers contacts the packaging bag under the action of the cylinder and pushes the packaging bag down and turns it. When pushing the bag, under the action of the pushing pair of rollers, the impact force of the bag pushing assembly on the packaging bag is effectively reduced;

[0013] (3) After the packaging bag is pushed down, it passes through the vibrating rods arranged inside the third conveyor belt. Due to the softness and plasticity of the packaging bag, the powdered emulsion explosive inside the bag is affected by the vibration and movement of the drum conveyor belt, so that the explosive naturally concentrates at a lower position, thereby reducing the possibility of accumulation and uneven distribution, and the flat packaging bag is beneficial for the manipulator to stack.

[0021] Referring to Figure 1 , a powder emulsion explosive conveying device includes a bag packaging machine 1, a bag pushing assembly 3 and a weighing platform 7. A second conveyor belt 6 is installed at the upper end of the weighing platform 7. A first conveyor belt 2 is installed between the outlet of the bag packaging machine 1 and the inlet of the second conveyor belt 6. The conveying directions of the first conveyor belt 2 and the second conveyor belt 6 are the same. A fourth conveyor belt 9 is provided on one side of the second conveyor belt 6 perpendicular to the conveying direction. The conveying direction of the fourth conveyor belt 9 is perpendicular to the conveying direction of the second conveyor belt 6. A bag pushing assembly 3 is installed on the side of the second conveyor belt 6 away from the fourth conveyor belt 9.

[0022] Obviously, based on the above, the packaging bag is conveyed in an upright state from the first conveyor belt 2 to the second conveyor belt 6. The packaging bag is conveyed to a specified position on the second conveyor belt 6, weighed by the weighing platform 7, and the bag pushing assembly 3 pushes the packaging bag down onto the conveyor belt in the next set of vertical directions, completing the functions of weighing, bag pushing and turning.

[0023] Referring to Figure 2 , in this embodiment, the bag pushing assembly 3 includes a mounting plate 31 and pushing counter-rollers 35. A mounting groove 34 is opened on one side of the mounting plate 31 close to the second conveyor belt 6. A rotating shaft 38 is rotatably installed on the upper part inside the mounting groove 34. The pushing counter-rollers 35 are arranged at the lower part inside the mounting groove 34. Both ends of the pushing counter-rollers 35 are connected to the rotating shaft 38 through pushing counter-roller mounting rods 36. The pushing counter-rollers 35 are rotatably connected to the pushing counter-roller mounting rods 36. A push rod 33 is provided between the pushing counter-rollers 35 and the rotating shaft 38. The push rod 33 is connected to the pushing counter-roller mounting rod 36. A cylinder mounting groove 37 is opened at the position of the mounting groove 34 corresponding to the push rod 33. A cylinder 32 is installed inside the cylinder mounting groove 37. The telescopic end of the cylinder 32 is rotatably connected to the push rod 33.

[0024] Obviously, based on the above, when it is necessary to complete the functions of pushing the bag and turning, the cylinder 32 works, and the telescopic end of the cylinder 32 extends, causing the rotating shaft 38 to rotate. The pushing counter-rollers 35 at the bottom apply force to the packaging bag as the rotating shaft 38 rotates, causing the packaging bag to fall onto the next set of conveyor belts perpendicular to the conveying direction of the second conveyor belt 6.

[0025] Refer to Figure 3 , in this embodiment, a third conveyor belt 8 is installed between the second conveyor belt 6 and the fourth conveyor belt 9. The third conveyor belt 8 is a drum-type conveyor belt, and multiple sets of vibrating rods 82 are uniformly arranged along the surface at each set of drums 81 of the third conveyor belt 8.

[0026] Obviously, based on the above, the pushed-down packaging bag is conveyed forward under the action of the third conveyor belt 8. Since the third conveyor belt 8 is a drum-type conveyor belt, and due to the multiple sets of vibrating rods 82 uniformly arranged along the surface at each set of drums 81, the powdered emulsion explosive in the bag is affected by the vibration and movement of the drum conveyor belt, causing the explosive to naturally concentrate at a lower position, thereby reducing the possibility of accumulation and uneven distribution, and the flat packaging bag is conducive to robotic palletizing.

[0027] In this embodiment, equipotential bonding is carried out on the positioning bolts of the drums 81.

[0028] Obviously, based on the above, the static electricity generated by the vibration and friction of the packaging bag on the drum conveyor belt is eliminated.

[0029] Refer to Figure 1 , in this embodiment, a photoelectric detection switch 5 that provides control signals for the bag-pushing assembly 3 and the second conveyor belt 6 is installed on the side of the second conveyor belt 6 away from the first conveyor belt 2.

[0030] Obviously, based on the above, when the packaging bag is conveyed to the position of the photoelectric detection switch 5, the photoelectric detection switch 5 detects the packaging bag, the second conveyor belt 6 stops working. After the telescopic end of the cylinder 32 extends to a preset length, the packaging bag is pushed down onto the upper end of the third conveyor belt 8 and then the telescopic end of the cylinder 32 resets. The packaging bag is conveyed forward along the third conveyor belt 8. When the photoelectric detection switch 5 does not detect the packaging bag, the second conveyor belt 6 starts working again.

[0031] Refer to Figure 1 , in this embodiment, a control cabinet 4 with a display screen is installed on the side wall of the bag-pushing assembly 3.

[0032] Obviously, based on the above, it is convenient for the operator to monitor the operation of the equipment and adjust the operation data at the same time.

[0033] To more clearly illustrate the solutions and effects of this embodiment, examples are given in combination with the attached drawings:

[0034] Refer to Figures 1 - 3, the packaging bag filled with materials is led out from the outlet of the bag packaging machine 1 to the upper end of the first conveyor belt 2. The first conveyor belt 2 drives the packaging bag to be conveyed to the upper end of the second conveyor belt 6. The second conveyor belt 6 drives the packaging bag to be conveyed to the designated position. When the photoelectric detection switch 5 detects the packaging bag, the second conveyor belt 6 stops working. After the telescopic end of the cylinder 32 extends to the preset length, the packaging bag is pushed down to the upper end of the third conveyor belt 8 and then the telescopic end of the cylinder 32 resets. The packaging bag is conveyed forward along the third conveyor belt 8 to the upper end of the fourth conveyor belt 9 and conveyed to the next process. When the photoelectric detection switch 5 does not detect the packaging bag, the second conveyor belt 6 starts working again. Repeat the above steps until all the packaging bags are conveyed.
