Description

Technical Field

[0001] The invention relates to the technical field of bag unpacking equipment, and in particular to a solid ammonium nitrate crushing and bag unpacking device. Background Art

[0002] Ammonium nitrate is the main raw material for industrial explosives. During the production process, ammonium nitrate needs to be taken out of the bagged packaging. This process is usually completed manually. However, ammonium nitrate is very easy to absorb moisture during storage. After absorbing moisture, it will recrystallize, causing the granular or powdered ammonium nitrate to form lumps of material, which is not conducive to unpacking and taking out. Therefore, it needs to be broken and opened before it can be taken out for use.

[0003] At present, the usual method of dealing with agglomerated bagged ammonium nitrate encountered in production is to break it up manually and then break the bag as regular bagged material. However, the manual crushing effect is poor, and it is likely that a small amount of material will not be broken. This will easily lead to material hanging in the bag after the bag breaking process. The hanging material in the bag poses a safety hazard, and the manual crushing method is inefficient and will pose a health threat to workers.

[0034] The conveying direction of the conveying roller 12 is the same as the length direction of the installation fixed platform 3. The end of the conveying direction of the conveying roller 12 is adjacent to the end of the installation fixed platform 3. A transverse bag breaking mechanism 2 is fixedly installed on the bale pressing and crushing mechanism bracket 11 below the end of the conveying roller 12. The transverse bag breaking mechanism 2 is located between the bale pressing and crushing mechanism bracket 11 and the installation fixed platform 3.

[0035] The transverse bag breaking mechanism 2 is used to open the bottom of the ammonium nitrate packaging bag passing over it. When the buffer conveying mechanism 10 is not used, the transverse bag breaking mechanism 2 is fixedly installed on the side of the bag pressing and crushing mechanism 1 close to the installation fixed platform 3, or fixedly installed on the side of the installation fixed platform 3 close to the bag pressing and crushing mechanism 1. When the buffer conveying mechanism 10 is used, the transverse bag breaking mechanism 2 is fixedly installed on the side of the buffer conveying mechanism 10 close to the installation fixed platform 3, or fixedly installed on the side of the installation fixed platform 3 close to the buffer conveying mechanism 10. The transverse bag breaking mechanism 2 includes a guide rail 21, a slider 22, a cutting drive cylinder 23, a folding drive cylinder 24 and a transverse blade 25. The guide rail 21 is fixedly installed on one end of the bag pressing and crushing mechanism bracket 11 close to the installation fixed platform 3. The guide rail 21 is parallel to the plane where the conveying roller 12 is located. As a specific embodiment, the length direction of the guide rail 21 is parallel to the conveying direction of the conveying roller 12. The slider 22 is vertically slidably installed on the guide rail 21, the cutting drive cylinder 23 is fixedly installed on one side of the guide rail 21, and the output shaft of the cutting drive cylinder 23 is parallel to the guide rail 21, and its output shaft is fixedly connected to the slider 22, the end of the transverse blade 25 is hinged to the surface of the slider 22, the cylinder body of the folding drive cylinder 24 is hinged to the slider 22, and the end of the output shaft of the folding drive cylinder 24 is hinged to the blade of the transverse blade 25. In the above scheme, the transverse blade 25 is folded and lodged relative to the slider 22 as the output shaft of the drive cylinder 24 is extended and retracted. When the transverse blade 25 is lodged, the highest point of the transverse bag breaking mechanism 2 does not exceed the horizontal plane where the upper surface of the conveying roller 12 is located. When the transverse blade 25 is erected, its blade passes through the horizontal plane where the upper surface of the conveying roller 12 is located. As a further specific implementation method, the output shafts of the transverse blade 25 and the folding drive cylinder 24 are all in the same plane, and the plane is parallel to the guide rail 21.

[0036] The transmission belt 9 is used to drive the reciprocating conveying mechanism 4 to perform reciprocating motion on the mounting fixed platform 3. The transmission belt 9 includes a driving unit, a belt roller and a belt. The belt is horizontally arranged in the middle of the mounting fixed platform 3. Both ends of the belt are supported by the belt rollers. The driving motor is connected to one of the belt rollers. The movement direction of the belt is the same as the length direction of the mounting fixed platform 3.

[0037] The reciprocating conveying mechanism 4 is used to convey the bagged ammonium nitrate on the pressing and crushing mechanism 1 to the other end of the fixed installation platform 3, and perform corresponding material shaking and bag taking processes. At the same time, the reciprocating conveying mechanism 4 is also provided with a corresponding longitudinal bag breaking mechanism 5 for longitudinally cutting and breaking the packaging bags.

[0038] The reciprocating conveying mechanism 4 includes a conveying trolley body 41, guide wheels 42, and a transport platform 43. There are several guide wheels 42, which are installed in an array on the conveying trolley body 41. The guide wheels 42 cooperate with the mounting fixed platform 3 to realize the sliding of the conveying trolley body 41 on the mounting fixed platform 3. The transport platform 43 is fixedly installed on the conveying trolley body. The conveying trolley body 41 is fixedly connected to the belt surface of the transmission belt 9. When the belt moves, the conveying trolley body 41 moves accordingly, thereby driving the transport platform 43 to move.

[0039] When the transport mechanism 4 moves to one end of the fixed installation platform 3 close to the bale pressing and crushing mechanism bracket 11, the conveying roller 12 transports the crushed packaging bags to the surface of the transport platform 43. During the transportation process, the lower surface of the packaging bags is subjected to several horizontal bag breaking treatments by controlling the operation of the horizontal bag breaking mechanism 2. The packaging bags that have been horizontally broken are completely transported to the surface of the transport platform 43 and are transported to the end of the fixed installation platform 3 away from the bale pressing and crushing mechanism bracket 11 for the next step of processing.

[0040] In a specific embodiment, the surface of the transport platform 43 is a roller structure or a belt structure, so that it can cooperate with the conveying roller 12 to achieve smooth transportation of bagged ammonium nitrate. The conveying direction of the roller structure or belt structure on the surface of the transport platform 43 is the same as the length direction of the fixed installation platform.

[0041] In a specific embodiment, a longitudinal bag breaking mechanism 5 is provided at one end of the transport platform 43 away from the transverse bag breaking mechanism 2. When the transport platform 43 moves to the positioning and clamping mechanism 6, the positioning and clamping mechanism 6 positions and clamps the packaging bag. At this time, the transport platform 43 returns to the bag pressing and crushing mechanism 1, and the bagged ammonium nitrate is pulled down from the transport platform 43. During the falling process, the longitudinal bag breaking mechanism 5 cuts and breaks the lower surface of the packaging bag to achieve the purpose of longitudinal bag breaking.

[0042] The longitudinal bag breaking mechanism 5 includes a rotating cylinder 51 and a longitudinal blade 52. The rotating cylinder 51 is fixedly mounted on an end of the transport platform 43 away from the transverse bag breaking mechanism 2. The output shaft of the rotating cylinder 51 is parallel to the upper surface of the transport platform 43 and perpendicular to the length direction of the fixed installation platform 3. The longitudinal blade 52 is fixedly mounted on the output shaft of the rotating cylinder 51, and the plane where the longitudinal blade 52 is located is perpendicular to the output shaft of the rotating cylinder 51. The rotating cylinder 51 drives the longitudinal blade 52 to rotate, thereby changing the distance between the end of the longitudinal blade 52 and the surface of the packaging bag, thereby achieving the effect of changing the longitudinal cutting and breaking of the bag.

[0043] The positioning and clamping mechanism 6 includes a positioning and clamping cylinder 61, an ejector pin 62, and a positioning bracket 63. Preferably, a support bracket is provided at one end of the mounting and fixing platform 3 away from the packing and crushing mechanism 1, and the positioning and clamping cylinder 61 is fixedly installed on the support bracket. The ejector pin is fixedly installed on the output shaft of the positioning and clamping cylinder 61. The positioning bracket 63 is fixedly installed on the mounting and fixing platform 3 below the positioning and clamping cylinder 61. The positioning bracket 63 is also provided with a corresponding positioning hole 631. The positioning and clamping cylinder 61 drives the ejector pin 62 to reciprocate in the vertical direction. , so that the ejector pin 62 is selectively embedded in the positioning hole 631 of the positioning bracket 63, and the transportation platform 43 will selectively enter between the positioning clamping cylinder 61 and the positioning bracket 63 during the movement, so that the ammonium nitrate packaging bag also enters between the two. When reaching the outside, the positioning clamping cylinder 61 drives the ejector pin 62 to fall and clamp the edge of the packaging bag in the positioning hole 631, thereby achieving clamping and positioning of the edge of the packaging bag. At this time, the return movement of the transportation platform 43 is cooperated to separate the packaging bag from the transportation platform 43.

[0044] The shaking mechanism 7 is used to cooperate with the positioning and clamping mechanism 6 to shake the packaging bag after the bag is broken to prevent the material from hanging in the bag. The shaking mechanism 7 includes a flapping frame 71, a fixed shaft 72, a connecting plate 73, and a flapping drive cylinder 74. One side of the flapping frame 71 is fixedly connected to the fixed shaft 72, and the fixed shaft 72 is rotatably connected to the mounting fixed platform 3. The connecting plate 73 is vertically fixedly installed at both ends of the fixed shaft 72. The cylinder body of the flapping drive cylinder 74 is hinged to the mounting fixed platform 3, and the output shaft of the flapping drive cylinder 74 is connected to the connecting plate 7 The end of the flapping frame 71 away from the fixed shaft 72 is hingedly connected. Preferably, the flapping frame 71 is located at the outer ring of the positioning bracket 63, and when the transportation platform 43 moves to the position of the positioning clamping mechanism 6, the flapping frame 71 is located below the transportation platform 43. When the packaging bag is separated from the transportation platform 43, the packaging bag falls on the flapping frame 71, and the end of the flapping frame connecting plate 73 is driven to reciprocate by the flapping drive cylinder 74, thereby realizing the rotation of the fixed shaft 72, further realizing the flapping action of the flapping frame, and flapping and separating the materials on the packaging bag.

[0045] The bag taking mechanism 8 includes a linear module 81, a telescopic drive cylinder 82 and a clamping claw 83. The linear module 81 is fixedly mounted on the mounting fixed platform 3, preferably, also mounted on the support frame, and the length direction of the linear module 81 is the same as the length direction of the mounting fixed platform 3. The cylinder body of the telescopic drive cylinder 82 is fixedly mounted on the slider of the linear module 81, and the clamping claw 83 is fixedly mounted on the output shaft of the telescopic drive cylinder 82. The telescopic drive cylinder 82 works on the linear module 81 to achieve approaching and moving away from the mounting fixed platform 3. The telescopic drive cylinder 82 can drive the clamping claw 83 to move between the linear module 81 and the output shaft of the telescopic drive cylinder 82. The output shaft moves in the direction of movement. Preferably, the output shaft of the telescopic drive cylinder 82 is arranged vertically downward. When the telescopic drive cylinder 82 is close to the mounting and fixing platform 3, the telescopic drive cylinder 82 can drive the clamping claw 83 to the vicinity of the positioning bracket 63, so as to clamp the edge of the packaging bag. When the shaking of the material is completed, the positioning clamping cylinder 61 drives the ejector pin 62 to leave the positioning bracket 63. At this time, the movement of the clamping claw 83 can separate the packaging bag from the mounting and fixing platform 3. The telescopic drive cylinder 82 can also continue to make reciprocating motion to shake the packaging bag, thereby further ensuring that there is no hanging material in the packaging bag.

[0046] The buffer conveying mechanism 10 includes a conveying trolley body 101 and a belt conveyor assembly 102. The buffer conveying mechanism is used to transport bagged ammonium nitrate from the bale pressing and crushing mechanism 1, and serves the purpose of connecting the bale pressing and crushing mechanism 1 with the installation fixed platform 3. The belt conveyor assembly 102 is fixedly installed on the conveying trolley body 101.

[0047] The bulk material silo 15 is used to store the crushed ammonium nitrate. The bulk material silo 15 is a silo body with an open upper end, which is fixedly installed below the mounting platform 3.

[0048] Workflow:

[0049] The packaging bag to be processed is placed on the conveyor roller 12, the compacting drive cylinder 13 compacts the packaging bag, and the crushing drive cylinder 14 crushes the ammonium nitrate in the packaging bag. After crushing, the compacting drive cylinder 13 releases the packaging bag, and the transport platform 43 moves to the end of the conveyor roller 12. The conveyor roller 12 and the transport platform 43 cooperate to work and transport the crushed bagged ammonium nitrate to the transport platform 43. At this time, the cutting drive cylinder 23 and the folding drive cylinder 24 work synchronously, and the transverse blade 25 performs multiple transverse cutting processes on the bottom of the packaging bag until the packaging bag is completely transported to the transport platform 43. The transmission belt 9 works and drives the transport platform 43 to be transported to the end of the installation fixed platform 3 away from the bag pressing and crushing mechanism 1. After transportation is completed, the positioning clamping cylinder 61 works to drive the ejector pin 62 to move downward and nail the edge of the packaging bag into the positioning hole 631. The rotating cylinder 51 works to rotate the longitudinal blade 52 to The surface of the packaging bag, at this time the transmission belt 9 and the transportation platform 43 work synchronously, so that the transportation platform 43 returns to the position of the bag pressing and crushing mechanism bracket 11, at this time the packaging bag is separated from the transportation platform 43 and is gradually cut open at the bottom by the longitudinal blade 52, so as to realize longitudinal bag opening, and after complete separation, the bottom of the packaging bag is completely opened, and the material falls with gravity, and the slapping drive cylinder 74 drives the cylinder slapping frame 71 to shake, thereby slapping the packaging bag until there is almost no residual material in the packaging bag, and stops slapping the drive cylinder 74, and the linear module 81 drives the telescopic drive cylinder 82 to move to the attachment of the installation fixed platform 3, and the telescopic drive cylinder 82 drives the clamping claw 83 to move to the vicinity of the positioning bracket 63 to clamp the edge of the packaging bag, and the telescopic drive cylinder 82 drives the clamping claw 83 to make a reciprocating motion in the vertical direction to further shake the packaging bag, and at the same time the linear module 81 is away from the installation fixed platform 3, so as to transport the empty bag to other positions.
