Description

Ammonium nitrate fuel oil explosive envelope auxiliary device

Technical Field

The utility model belongs to the technical field of explosive production, and particularly relates to an ammonium nitrate fuel oil explosive envelope auxiliary device.

However, this solution has the following drawbacks: after the material is filled, the bag mouth of the woven bag can be changed into a flat shape, but the powder material still has certain fluidity in the woven bag, the bag mouth which is changed into a flat shape is easy to deform due to vibration of a conveying line or material flow in the bag in the conveying process of the woven bag on the conveying line, and the powder material is difficult to smoothly enter a sealing module, or the bag mouth is inclined when entering the sealing module, so that poor sealing is caused, and ammonium nitrate fuel oil explosive is leaked from the woven bag.

If the bag mouth is not tightly sealed, the ammonium nitrate fuel oil explosive is easy to leak from the woven bag, on one hand, larger waste is generated, and the powder and granular materials are difficult to recover. In addition, the dropped ammonium nitrate fuel oil explosive has a great potential safety hazard.

Example 1

Referring to fig. 1, this embodiment provides an ammonium nitrate fuel oil explosive envelope auxiliary device, so as to solve the problem that the conventional ammonium nitrate fuel oil explosive packaging bag is transported on a transport line and the opening of the bag is easy to deform. The device comprises a conveyor line 100 and a conveyor assistance mechanism 200 adapted to the conveyor line 100.

Referring to fig. 1 and 2, the conveying auxiliary mechanism 200 includes a slipway base 1, a bag mouth shaping assembly 2 mounted on the slipway base 1, and a bag body limiting assembly 3. The sliding table base 1 comprises a sliding plate 101 and side plates 102 symmetrically arranged on the upper surface of the sliding plate 101, and the bottoms of the side plates 102 and the upper surface of the sliding plate 101 are supported in a reinforced mode through wedges. The slipway base 1 is arranged below the conveying line 100 and can drive the sliding plate 101 to slide reciprocally along the length direction of the conveying line 100, and the two side plates 102 are positioned on two sides of the conveying line 100 and extend out of the upper surface of the conveying line 100.

Referring to fig. 2 and 4, the bag shaping assembly 2 is symmetrically installed on two side plates 102, the bag shaping assembly 2 includes a first driving cylinder 201 and a bag extrusion plate 202, a cylinder body of the first driving cylinder 201 is installed on the side plate 102, an extrusion part is fixed at a movable end of the first driving cylinder 201, and the two bag extrusion plates 202 can be close to or far from each other under the driving of the two first driving cylinders 201.

The bag body limiting assembly 3 is arranged below the bag mouth shaping assembly 2, the bag body limiting assembly 3 comprises a second driving air cylinder 301 and a bag body limiting plate 302, the cylinder body of the second driving air cylinder 301 is fixedly arranged on the side plate 102, the bag body limiting plate 302 is fixed at the movable end of the second driving air cylinder 301, and the two bag body limiting plates 302 clamp the bag body from two sides under the driving of the two second driving air cylinders 301.

The bag body limiting plate 302 preferably adopts an arc shape matched with the bag body.

In operation, the woven bag is filled with ammonium nitrate fuel oil explosive onto the conveyor line 100 and conveyed rearwardly. At this time, the first driving cylinders 201 at both sides drive the two bag mouth extrusion plates 202 to extrude the bag mouth of the woven bag into a flat shape, and the second driving cylinders 301 drive the bag body limiting plates 302 to abut against the bag body from both sides. Then, the slipway base 1 drives the bag mouth shaping assembly 2 and the bag body limiting assembly 3 to keep a clamping state, and synchronously moves to the sealing module along with the conveying line 100. Subsequently, the sliding table base 1 pauses to operate, and simultaneously the first driving air cylinder 201 drives the two bag mouth extrusion plates 202 to be far away from the bag mouth loosening opening, and the second driving air cylinder 301 drives the bag body limiting plate 302 to be away from the bag body, so that the conveying line 100 continuously operates, and the bag mouth is guaranteed to be flat and the woven bags are conveyed into the sealing module. Finally, the slipway base 1 drives the bag mouth shaping assembly 2 and the bag body limiting assembly 3 to return to the starting point, clamps the next woven bag and sequentially reciprocates.

As a preferable scheme, the surface of the pocket extrusion plate 202 is provided with a plurality of notches 2021, so that the contact surface of the two pocket extrusion plates 202 forms negative pressure to suck and separate the flat pocket openings in the process that the first driving cylinder 201 drives the two pocket extrusion plates 202 to release the pocket openings.

Based on the first embodiment, the second embodiment is different in that:

referring to fig. 5 and 6, the bag mouth extrusion plate 202 is replaced by an extrusion belt conveyor 203, the movable end of the first driving cylinder 201 is fixedly connected with a "U" shaped mounting member 2031, and two inner walls of the "U" shaped mounting member 2031 are fixedly connected with two sides of the extrusion belt conveyor 203. The conveying surfaces of the two extrusion belt conveyors 203 can be tightly attached to each other under the driving of the first driving cylinders 201 on both sides.

The woven bag full ammonium nitrate fuel oil explosive falls onto the conveyor line 100 and is conveyed rearwardly. At this time, the extrusion belt conveyor 203 does not rotate, and the extrusion belt conveyor 203 has the same function as the bag mouth extrusion plate 202, that is, the bag mouth of the woven bag is extruded into a flat shape under the drive of the first driving cylinder 201. When the slipway base 1 drives the bag mouth shaping assembly 2 and the bag body limiting assembly to move to the sealing module, the slipway base 1 pauses operation, simultaneously starts the extrusion belt conveyor 203 and keeps synchronous operation with the conveying line 100, and can keep the bag mouth to be always clamped into a flat shape and conveyed into the sealing module, so that the phenomenon that the bag mouth is pulled out due to untimely loosening of the bag mouth extrusion plate 202 when the slipway base 1 stops operation is avoided.
