Technical Field
[0001] The utility model relates to the technical field of packaging, in particular to a device for folding the edges of the sealed opening of the finished product of expanded ammonium nitrate explosive. Background Technique
[0002] Expanded ammonium nitrate explosive is a kind of powdery mixed explosive mainly composed of expanded (with multi-microporous and flaky structure) ammonium nitrate as the main oxidant, an appropriate amount of combustible agent and other functional additives. Its multi-microporous structure has a sensitizing effect that can form hot spots for initiation, and there is no need to add sensitizers such as single-component explosives, highly sensitive salts or metal powders in general industrial explosives, which can reduce costs, reduce pollution and the risks in production and use.
[0003] The finished product packaging of expanded ammonium nitrate explosive is to uniformly place the bagged explosive packages into an open carton, and then use a tape sealing machine to perform edge folding treatment on the opening at the top of the carton. However, in the existing device during use, it is necessary for workers to manually close the side cover plates on the four sides of the top of the carton in advance before the tape sealing machine can work properly. Although the packaging operation of the tape sealing machine is simple, manually closing the side cover plates each time undoubtedly increases the workload, prolongs the working time, is not conducive to the efficient progress of work, and affects the production efficiency. Therefore, we design a device for folding the edges of the sealed opening of the finished product of expanded ammonium nitrate explosive to solve the above technical problems.

For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood according to specific situations.
[0020] Please refer to Figures 1-4, in the embodiment of the present utility model, a device for folding the edge of the package of the finished expanded ammonium nitrate explosive includes a conveyor belt 2 arranged on a conveyor base 1. A tape automatic carton sealer 3 is provided on the top of the conveyor base 1. The tape automatic carton sealer 3 is a prior art, which is easy to implement and not the innovative part of this device, so it will not be elaborated in detail. A fixed block is provided on the inner top wall of the left end inlet of the tape automatic carton sealer 3, and a limiting plate 8 is provided at the bottom of the fixed block. The left end of the limiting plate 8 extends outside the tape automatic carton sealer 3 and is tilted upward. Two first electric push rods 7 are inserted on the top of the conveyor base 1 and located on the left side of the tape automatic carton sealer 3. The two first electric push rods 7 are symmetrically distributed on the front and rear sides of the conveyor belt 2. The output end of the first electric push rod 7 is connected with a lifting plate 17. On the top of the mutually approaching ends of the two lifting plates 17, there is a vertical plate 18. A butting plate 19 is slidably inserted on the vertical plate 18. On the symmetrically arranged outer sides of the two vertical plates 18 away from each other, there is a second electric push rod 20. The output end of the second electric push rod 20 is provided with a connecting rod 21, and the other end of the connecting rod 21 is fixedly connected to the bottom edge of the butting plate 19.
[0021] A side plate 4 is fixedly provided on the rear surface of the conveyor base 1. The side plate 4 is located directly behind the first electric push rod 7. In the middle of the bottom of the rear surface of the side plate 4, there is a third electric push rod 9. Two mutually parallel sliding grooves 5 are formed through the surface of the side plate 4. The two sliding grooves 5 are symmetrically distributed on the left and right sides of the third electric push rod 9. A lifting rod 6 is slidably arranged in the sliding groove 5. The rear ends of the two lifting rods 6 extend to the rear of the side plate 4 and are connected to the same cross bar 10. The cross bar 10 is integrally formed with the two lifting rods 6. The cross bar 10 is slidably connected to the rear surface of the side plate 4. The output end of the third electric push rod 9 is fixedly connected to the bottom of the cross bar 10. The front end of the lifting rod 6 is provided with a motor 11. The output shaft of the motor 11 is connected with a rotating block 12. The rotating block 12 is located above the conveyor belt 2. On the symmetrically arranged mutually approaching sides of the two rotating blocks 12, there is a telescopic column 13. The other end of the telescopic column 13 is connected with a U-shaped frame 14. An extrusion roller 15 is rotatably arranged inside the U-shaped frame 14. A spring 16 is sleeved outside the telescopic column 13. One end of the spring 16 is connected with the U-shaped frame 14 and the other end is connected with the rotating block 12.
[0022] The top of the vertical plate 18 is of an arc surface structure, and the mutually approaching sides of the two butting plates 19 are also of an arc surface structure. When the vertical plate 18 or the butting plate 19 contacts the surface of the carton, the design of the arc surface structure can protect the surface of the carton and prevent the surface of the carton from being scratched.
[0023] When this device is in use, place the cardboard box containing multiple explosive bags on the conveyor belt 2 and it will be transported to the right along with the conveyor belt 2. When it stops between the two first electric push rods 7, at this time, the third electric push rod 9 and the motor 11 work first to turn over the side cover plates I on the shorter sides of the left and right sides of the top of the cardboard box. The specific operations are as follows: In the initial state, the third electric push rod 9 extends to the longest, and the motor 11 controls the rotating block 12 to rotate to an inclined state, that is, the two telescopic columns 13 are in an inclined state in a "V" shape. Therefore, the distance between the two pressing rollers 15 becomes larger and is greater than the length of the cardboard box. Then start the third electric push rod 9 to control the cross bar 10 to descend, which can drive the two pressing rollers 15 to descend to the lower part outside the cardboard box. Subsequently, start the motor 11 to control the rotating block 12 to rotate to a horizontal state, that is, the two telescopic columns 13 are in a horizontal state. At this time, the distance between the two pressing rollers 15 becomes smaller, and the pressing rollers 15 are in contact with the outer walls of the left and right sides of the cardboard box, and the telescopic columns 13 contract, and the spring 16 is in a compressed state. Then make the third electric push rod 9 extend to drive the pressing rollers 15 to move upward. This process can push the side cover plate I upward to turn over. When the pressing rollers 15 move above the side of the cardboard box, the elastic force of the spring 16 is released to drive the telescopic columns 13 to extend and reset, which can drive the two pressing rollers 15 to approach each other, and then can push the side cover plate I to continue to rotate until it is closed;
[0024] Next, the first electric push rod 7 works to turn over the side cover plates II on the longer sides of the front and back of the top of the cardboard box. The specific operations are as follows: The first electric push rod 7 extends and drives the lifting plate 17, the vertical plate 18 and the abutting plate 19 to move upward together, and during the movement, it pushes the side cover plate II to turn over. When the abutting plate 19 moves above the top of the cardboard box, the first electric push rod 7 stops and the second electric push rod 20 starts to drive the two abutting plates 19 to approach each other, which can push the side cover plate II to continue to rotate until it is closed. During the above process, the motor 11 starts quickly and controls the pressing rollers 15 to leave the top of the side cover plate I. As the side cover plate II rotates and closes, it can press the side cover plate I; Next, the conveyor belt 2 continues to work to drive the cardboard box to continue to move. During this process, the abutting plate 19 is always in contact with the side cover plate II until the front end of the top of the cardboard box abuts against the limiting plate 8. After the top of the cardboard box is separated from the abutting plate 19, it is continuously pressed by the limiting plate 8 and smoothly enters the automatic tape sealing machine 3 for sealing. This device does not require workers to manually close the side cover plates of the cardboard box, which saves time and effort, has a high degree of automation, and greatly improves work efficiency and is worthy of promotion.
[0025] It should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
