The iron nails 4 do not interfere with the round bars 6 when the second conveyor belt 3 rotates.
Before the bag body is used, a proper spring 12 is selected according to the size of the bag body and the amount of materials in the bag body, so that the spring 12 can not exceed the maximum bearing pressure of the bag body through the second conveyor belt 3 when the bag body enters between the first conveyor belt 2 and the second conveyor belt 3, the bag body can be compressed and then driven by external power to rotate by the first conveyor belt 2, when the bag body is placed at the left part of the first conveyor belt 2, the bag body enters the shell 1 from the left opening of the shell 1 under the driving of the first conveyor belt 2, the right end of the bag body is contacted with the iron nails 4 on the second conveyor belt 3 after entering the shell 1, and at the moment, the first conveyor belt 2 still drives the bag body to move rightwards, so that the right end of the bag body can push the second conveyor belt 3 to rotate through the iron nails 4, meanwhile, the bag body can be inserted into the bag body is gradually pressed between the first conveyor belt 2 and the second conveyor belt 3 under the continuous driving of the first conveyor belt 2, and the second conveyor belt 3 is lifted upwards, and the spring on the slide bar 11 is compressed;
because the second conveyor belt 3 is always pressed by the downward pushing force given by the springs 12, the first conveyor belt 2 and the second conveyor belt 3 compress the bag body, the material in the bag body tightly supports the front side and the rear side of the bag body, the bag body continuously moves rightwards along with the first conveyor belt 2 and contacts with the cutting knife 5, the cutting knife 5 is connected with the upper and lower cross beams 10 by the two equal-length connecting rods 13, and the hinging points of the two connecting rods 13 and the cross beams 10 are positioned on the same vertical line, according to the principle that the top point of the isosceles triangle is positioned on the middle vertical line of the bottom line, the two cutting knives 5 are always positioned in the center of the interval between the first conveyor belt 2 and the second conveyor belt 3, so that the cutting knife 5 can cut in from the foremost side and the rearmost side of the bag body and cut the bag body, the material begins to fall, the spring 12 is reduced to avoid the friction force between the bag body and the first conveyor belt 2 and the second conveyor belt 3 from being reduced after the bag body is cut, and finally the problem that the second conveyor belt 3 cannot rotate is caused, and the bag body needs to be ensured to enter between the first conveyor belt 2 and the second conveyor belt 3 when the bag body is cut by the first conveyor belt 5;
the next bag body is pressed by the first conveyor belt 2 and the second conveyor belt 3, and the rotation of the first conveyor belt 2 is transmitted to the second conveyor belt 3, so that the cut bag body can still move rightwards under the dragging of the iron nails 4 and gradually is transferred to the round rod 6 from the first conveyor belt 2, and the cushion block 15 is fixed at the left end of the round rod 6, so that the cushion block 15 can reduce the interval between the round rod 6 and the second conveyor belt 3, even if materials continuously fall off, the thickness of the bag body is continuously reduced, the cushion block 15 can also support the bag body upwards, the bag body is prevented from being separated from the iron nails 4, the iron nails 4 can still drag the bag body to move rightwards, the cutting knife 5 can cut the front side and the rear side of the bag body, the round rod 6 is positioned on the symmetrical surfaces of the front side and the rear side of the first conveyor belt 2, the iron nails 4 on the second conveyor belt 3 are always inserted into the bag body, and the bag body cannot fall off to one side when sliding on the round rod 6;
the bag body moves rightwards on the continuous round bar 6 under the dragging of the iron nails 4, meanwhile, materials fall from two sides of the round bar 6, the bag body is dragged to the upper part of the second conveyor belt 3 by the iron nails 4 after passing through the rightmost end of the second conveyor belt 3, and is lifted from the second conveyor belt 3 at the bag outlet 8 by a plurality of inclined short bars 9, and then is intensively stored by workers, and as the left end of the short bars 9 is hinged with the bag outlet 8, the short bars 9 can rotate around a hinged shaft, even if the second conveyor belt 3 moves up and down in use, the short bars 9 can be in sliding contact with the second conveyor belt 3 at any time, so that the empty bag body is prevented from continuing to rotate along with the second conveyor belt 3;
when the bag body is disassembled to the last bag body, the next bag body is not arranged at the rear part and continuously transmits the rotation of the first conveyor belt 2 to the second conveyor belt 3, so that after the last bag body is cut, the first conveyor belt 2 is transferred to the round rod 6, and the second conveyor belt 3 has no driving force, so that the bag body cannot continuously discharge and discharge bags, and an operator is required to rotate the manual rocking bar 16 at the moment to drive the second conveyor belt 3 to rotate, and then the last bag body is discharged.
When the bag body moves rightwards on the round rod 6 under the dragging of the iron nail 4, the left end of the round rod 6 is lower than the right end, so that the bag body is in an inclined state on the round rod 6, meanwhile, the bag body can be driven by the iron nail 4 to turn upwards and downwards when at the rightmost end of the second conveyor belt 3, and the bag body can be inclined again when being lifted up from the bag outlet 8 by the short rod 9, so that materials which are not completely dropped on the round rod 6, such as materials at four bag corners, slide again in the process, and the material waste is reduced.
The invention has the following remarkable advantages:
1. according to the invention, the bag bodies are tightly pressed by the first conveyor belt 2 and the second conveyor belt 3, and the iron nails 4 are inserted into the bag bodies, so that the continuously-changed bag bodies are used as transmission blocks for the first conveyor belt 2 to drive the second conveyor belt 3 to rotate, and meanwhile, the second conveyor belt 3 drives each bag body to pass through the cutting knife 5, and the discharging and empty bag separating process is carried out, so that manual interference is not needed, the working condition of a factory assembly line is very fitted, the structure is compact and ingenious, the occupied area is small, and the practicability is strong.
2. Under the condition that the bag body is pressed by the first conveyor belt 2 and the second conveyor belt 3, the front side and the rear side of the bag body are cut by the two cutters 5 on the front side and the rear side, materials start to fall off, and then the cut bag body is moved to the round rod 6 by the second conveyor belt 3, so that the materials continue to fall off from the two sides of the round rod 6, the damage degree of the bag body is small, the situation that bag body fragments are mixed into the materials can not occur, and the bag body and the materials do not need to be screened, so that the feeding speed is greatly improved, and the production efficiency is improved.
3. According to the invention, through the inclined round rod 6 and the bag body which is turned up and down at the right end of the second conveyor belt 3 and the bag outlet 8, the bag body is inclined and lifted, so that the residual materials in the discharged bag body drop again, the utilization rate of the materials is improved, and the cost is saved.
4. The cutting knife 5 is connected with the upper cross beam 10 and the lower cross beam 10 through the two equal-length connecting rods 13, and the hinging points of the two connecting rods 13 and the cross beam 10 are positioned on the same plumb line, so that the cutting knife 5 is always positioned at the center position between the first conveyor belt 2 and the second conveyor belt 3, the cutting knife 5 can directly cut the foremost end and the rearmost end of the tightly supported bag body, and the situation that the cutting knife 5 cannot cut the bag body due to the fact that the cutting knife 5 is positioned on the upper side or the lower side of the bag body when the bag body is cut is avoided.
