Description

Technical Field

[0001] The present invention relates to the technical field of bag unpacking, and in particular to fully automatic unpacking equipment for solid ammonium nitrate used in civil explosive products. Background Art

[0002] In the production process of civil explosives, solid ammonium nitrate is the core raw material. In order to ensure its transportation and storage safety, a double-layer packaging structure is often adopted. The outer layer is usually a high-strength woven bag to resist external physical impact, and the inner layer is a moisture-proof plastic film bag to prevent the ammonium nitrate from getting damp and deteriorating. Ammonium nitrate is flammable and explosive, so even a slight friction or static electricity may cause serious safety accidents. Therefore, violent impact should be avoided when unpacking. Since ammonium nitrate dust may cause explosions and other dangers, dry sweeping should be avoided when cleaning.

[0003] Chinese patent CN118164038B discloses an automatic unpacking device for bags of solid ammonium nitrate material for industrial explosives, which includes a roller conveyor line, a workbench, an active roller, a driven roller and a material receiving bin. The workbench is arranged at the unloading end of the roller conveyor line; the active roller is arranged between the workbench and the roller conveyor line, and the circumference of the active roller is connected to two active sprockets, and the circumference of the driven roller is connected to two driven sprockets. Chains are wound between the two pairs of active sprockets and the driven sprockets, and the end of the active roller is provided with a first driving member for driving the active roller to rotate; the surfaces of the two chains close to each other are connected with multiple spikes; the side of the workbench close to the driven roller is provided with an installation opening, and a cutting blade is provided in the installation opening, and the cutting blade partially extends out of the top surface of the workbench, and a second driving member for driving the cutting blade to rotate is installed on the bottom surface of the workbench; the material receiving bin is arranged below the two chains. This application has the effect of improving the unpacking efficiency of the unpacking device.

[0004] However, in actual use, it was found that the existing technology can only unpack ammonium nitrate in single-layer packaging, and some ammonium nitrate remains inside the packaging bag, which requires manual processing, which is time-consuming and labor-intensive. Currently, the unpacking of double-layered ammonium nitrate mainly relies on manual unpacking or semi-automatic equipment to assist in unpacking. Manual unpacking is labor-intensive and inefficient, and it is very easy to cut the inner bag during operation, causing material leakage. At the same time, manual contact is prone to explosion accidents due to friction and static electricity. Semi-automatic equipment is not designed for double-layer packaging, and there are problems such as difficult to control the cutting depth and incomplete separation of packaging and materials. It is also unable to classify and recycle the inner and outer layers of packaging. Summary of the Invention

When the packaging bag passes through the surface of the perforated pressure roller 422, the negative pressure will adsorb the outer bag or the inner bag, thereby realizing the preliminary separation of the outer bag and the inner bag. The negative pressure generated by the cooperation of the air pump 424 and the perforated pressure roller 422 is the key to separating the outer bag and the inner bag; the separation guide rail 425 is arranged inside the body 100.

[0033] In detail, the sixth motor 431 is arranged on the machine body 100, and its output shaft is connected to the brush roller 432. When the sixth motor 431 is powered on, the output shaft rotates to drive the brush roller 432 to rotate.

The cutting depth penetrates the two layers of material of the packaging bag, and the cutting length is controlled to leave a certain distance of uncut area at the tail of the bag body, thereby obtaining a rectangular plane structure that can be fully unfolded and without damage or gaps.

[0040] In this embodiment, by providing a bag pushing assembly 21, the function of pushing the ammonium nitrate packaging bag to a suitable cutting position is achieved, thereby providing a stable cutting object for the cutter assembly 22; through the cutter assembly 22, the function of cutting the ammonium nitrate packaging bag along the longitudinal center line according to specific requirements is achieved, thereby achieving the effect of obtaining a packaging bag of a specific shape that is convenient for subsequent processing.

[0041] Further, if Figure 5 As shown, the bag pushing assembly 21 includes: The driving member and the push plate 215 rotatably disposed on the driving member, the rotation angle of the push plate 215 is limited to a certain range.

[0042] In this embodiment, by providing a bag pushing assembly 21, the function of pushing the ammonium nitrate packaging bag to move is achieved, thereby achieving the goal of accurately allowing the packaging bag to reach a designated position, making it easier for the cutter assembly 22 to split the ammonium nitrate packaging bag.

[0043] In detail, the first motor 211 serves as a power source, and the output shaft of the first motor 211 is connected to the screw rod 212, driving the screw rod 212 to rotate. The screw rod 212 is threadedly matched with the slider 214. When the screw rod 212 rotates, the slider 214 will move linearly along the axial direction on the screw rod 212. At the same time, the slide bar 213 plays a guiding role. The slider 214 is sleeved on the slide bar 213 to ensure that the slider 214 can only move along the direction of the slide bar 213 and will not rotate with the rotation of the screw rod 212, making the movement of the slider 214 more stable and precise. A push plate 215 is fixedly installed on the slider 214. When the slider 214 moves linearly along the slide bar 213, the push plate 215 also moves accordingly. During the movement, when the push plate 215 contacts the ammonium nitrate packaging bag, it will apply thrust to the packaging bag, causing the packaging bag to move on the body 100. Since the rotation angle of the push plate 215 is limited to a certain range, when the ammonium nitrate bag comes over, the push plate 215 flips over. When the ammonium nitrate bag passes over, the push plate 215 flips to a vertical position due to gravity and is stuck by the slider 214.

[0044] It should be noted that the driving component includes: a first motor 211 , a screw rod 212 , a sliding rod 213 and a slider 214 .

[0045] Further, if Figure 6 As shown, the cutting knife assembly 22 includes: The second motor 221 and the cutting knife 222 are transmission-connected to the second motor 221 . The back of the cutting knife 222 is provided with rounded corners to prevent the cutting knife 222 from scratching the packaging bag after rotating.

[0046] In this embodiment, by setting up a cutting knife assembly 22, the function of performing specific cutting on the ammonium nitrate packaging bag along the longitudinal center line is achieved, thereby achieving the effect of obtaining a rectangular planar structure packaging bag that can be fully unfolded and has no damage or gaps, which facilitates subsequent processing of the packaging bag.

[0047] In detail, the second motor 221 generates power when working, driving the cutter 222 connected to it to move. When the cutter 222 is still a small distance away from the packaging bag, the second motor 221 controls the cutter 222 to flip. During this process, the blade of the cutter 222 contacts the ammonium nitrate packaging bag and cuts along the longitudinal center line. Since the cutter 222 flips in time, it avoids completely cutting through the packaging bag, so that a certain distance of uncut area is retained at the tail of the bag, and finally a complete long strip is formed. The back of the cutter 222 has rounded corners. During its movement, even if it has slight contact with other parts of the packaging bag except the cutting line, the rounded corners can prevent the packaging bag from being damaged, thereby ensuring the integrity of the packaging bag except the cutting line.

[0048] Example 2 like Figures 4 to 7 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that: It also includes: a screen pressing mechanism 3, the screen pressing mechanism 3 including: A first sieve plate 301 , the first sieve plate 301 is rotatably mounted on the machine body 100 ; A second sieve plate 302, which is rotatably connected to the first sieve plate 301; A connecting plate 303, the connecting plate 303 being arranged on the second sieve plate 302; A third motor 304 , the third motor 304 is disposed on the machine body 100 ; A crank rod 305 , the crank rod 305 being drivingly connected to an output shaft of the third motor 304 ; A collar 306 is sleeved on the curved rod 305 and connected to the connecting plate 303 to drive the first sieve plate 301 and the second sieve plate 302 to squeeze each other to crush the agglomerated ammonium nitrate; The output chamber 307 is provided inside the body 100 and is used for outputting ammonium nitrate.

[0049] In this embodiment, a screen pressing mechanism 3 is provided, in which the first sieve plate 301 and the second sieve plate 302 squeeze each other, thereby achieving the function of crushing the agglomerated ammonium nitrate, thereby achieving the effect of outputting the ammonium nitrate in a suitable granular state; through the first sieve plate 301, the second sieve plate 302 and the output chamber 307, the function of screening and outputting ammonium nitrate is achieved, thereby achieving the goal of transporting qualified ammonium nitrate.

[0050] In detail, the third motor 304 is provided on the body 100, and the rotation of its output shaft drives the rotation of the crank rod 305 connected thereto. A collar 306 is sleeved on the crank rod 305, and the rotation of the crank rod 305 causes the collar 306 to reciprocate. The collar 306 is connected to the connecting plate 303 provided on the second sieve plate 302. The reciprocating movement of the collar 306 drives the connecting plate 303 to move, thereby driving the second sieve plate 302 to move. Since the second sieve plate 302 is rotatably connected to the first sieve plate 301, the movement of the second sieve plate 302 causes the first sieve plate 301 and the second sieve plate 302 to squeeze each other; when the agglomerated ammonium nitrate enters between the first sieve plate 301 and the second sieve plate 302, it is crushed under the squeezing action of the two. The crushed ammonium nitrate is screened by the first sieve plate 301 and the second sieve plate 302, and the ammonium nitrate that meets the requirements passes through the sieve plates into the output chamber 307 provided inside the body 100 and is output from the output chamber 307.

[0051] Working steps During operation, the conveyor belt 101 of the conveying mechanism 1 conveys ammonium nitrate packaging bags, and the centering guide plate 102 centers the packaging bags. The first motor 211 of the bag pushing assembly 21 drives the screw 212 to rotate, driving the slider 214 and the push plate 215 to push the packaging bags to the cutting knife assembly 22. The second motor 221 drives the cutting knife 222 to cut the packaging bags. The fourth motor 411 of the acupuncture assembly 41 drives the acupuncture disk 413 to puncture the packaging bags and pull them to the negative pressure assembly 42. The fifth motor 421 drives the perforated pressure roller 422 to cooperate with the air pump 424 to separate the inner and outer bags. The cleaning assembly 43 uses the sixth motor 431 to drive the brush roller 432 in combination with the spray head 433 to wet-clean the residual ammonium nitrate in the inner bag. The seventh motor 441 of the collecting assembly 44 drives the drive roller 442 to convey the inner and outer bags to the corresponding collecting chamber. The pressing and screening mechanism 3 crushes and screens the ammonium nitrate and then outputs it from the output chamber 307.
