For ease of description, automated bag removal of collection tube 202 will be described.
The invention provides an automatic bag opening machine 100, as shown in fig. 1 to 7, for automatically opening a material bag 200, wherein the material bag 200 refers to a structure in which a material is sealed in a bag body 201, and comprises the material and the bag body 201. The automatic bag opening machine 100 comprises a feeding mechanism 1, an aligning mechanism 2, a conveying mechanism 3, a cutting mechanism 4 and a separating mechanism 5;
the feeding mechanism 1 is arranged above the positioning mechanism 2; wherein feed mechanism 1 is used for carrying out the material loading operation to material bag 200, transports the material to positioning mechanism 2.
The aligning mechanism 2 comprises a placing table 21 and a first extruding component 22, the feeding mechanism 1 transports materials to the placing table 21, the first extruding component 22 is movably arranged on the placing table 21, a first gap exists between the first extruding component 22 and the placing table 21, and the first extruding component 22 pushes the material bag 200 when moving relative to the placing table 21 so as to align the position of the materials in the material bag 200, such as the collecting pipe 202, relative to the bag body 201 and push the material bag 200 to the conveying mechanism 3; specifically, since the collection tube 202 may be located at any position relative to the bag body 201 in the initial state, such as at the center of the bag body 201, or placed in the bag body 201 in an inclined manner, in order to facilitate the next transportation and cutting operations, it is necessary to perform a positioning process on the collection tube 202 in the bag body 201, wherein the first pressing member 22 is movably disposed on the placing table 21 and has a first gap with the placing table 21, wherein the height of the first gap is greater than the thickness of the bag body 201 and less than the thickness of the collection tube 202, so that when the first pressing member 22 moves relative to the placing table 21, the bag body 201 can pass through the first gap, and the collection tube 202 cannot pass through the first gap, so as to press the collection tube 202, so that after the collection tube 202 moves relative to the bag body 201 in the bag body 201 to the side position of the bag body 201, the collection tube 202 is in the relatively static state in the bag body 201, and at this time, the first pressing member 22 continues to press the collection tube 202 to move the collection tube 201 from the placing table 21 to the transportation mechanism 3 for further transportation.

When the material bag 200 formed with the cutting opening is conveyed from the conveying mechanism 3 to the conveying table 51, the conveying table 51 conveys the material bag 200 to the second pressing member 52, and since the second pressing member 52 and the cutting mechanism 4 are spatially arranged on two opposite sides of the conveying mechanism 3, it should be noted that the arrangement of the second pressing member 52 and the cutting mechanism 4 on two opposite sides of the conveying mechanism 3 means: the second pressing member 52 and the cutting mechanism 4 are respectively located on a first side of the conveying mechanism 3 along the conveying direction thereof and a second side opposite to the first side, but the specific positions of the second pressing member 52 and the cutting mechanism 4 at the opposite sides of the conveying mechanism 3 are not limited; therefore, the side of the bag body 201 with the cutting opening is opposite to the second pressing member 52, and since the second gap height of the second pressing member 52 is larger than the thickness of the bag body 201 and smaller than the thickness of the material such as the collecting pipe 202, when the conveying table 51 conveys the material bag 200, the bag body 201 can pass through the second gap, but the collecting pipe 202 cannot pass through the second gap, so as to push the collecting pipe 202, so that the collecting pipe 202 and the bag body 201 move relatively, the collecting pipe 202 rolls out from the cutting opening of the bag body 201, the bag body 201 continues to move along the moving track of the conveying table 51, the collecting pipe 202 is left on the conveying table 51 by the block of the second pressing member 52, and since the collecting pipe 202 can form an inertia effect when conveyed by the conveying mechanism 3, the bag body 51 can continue to move along the extending direction of the moving track of the conveying mechanism 3, therefore, a collecting device can be arranged at the tail end of the conveying table 51 to collect the conveyed collecting pipe 202.
As can be seen from the above, the automatic bag breaker 100 operates substantially as follows:
the material bag 200 is conveyed to the placing platform 21 of the positioning mechanism 2 through the feeding mechanism 1;
after the placing table 21 of the positioning mechanism 2 receives the material bag 200, the first pressing member 22 moves relative to the placing table 21 and pushes the material in the material bag 200 to move to one side in the bag body 201 relative to the bag body 201, and pushes the material bag 200 to the conveying surface of the conveying mechanism 3;
the conveying mechanism 3 conveys the materials to the cutting mechanism 4, the cutting mechanism 4 cuts the bag body 201 to form a cutting opening, and the materials are conveyed to the conveying table 51 of the separating mechanism 5 continuously;
after the conveying table 51 receives the cut material bag 200, the conveying table 51 moves towards the direction of the second pressing member 52 with the animal material bag 200, the second pressing member 52 presses the material bag 200 and separates the material from the cut opening relative to the bag body 201, the bag body 201 continues to move along the movement track of the conveying table 51, and the material is retained on the conveying table 51 by the blocking of the second pressing member 52 and continues to move forwards along the extending direction of the movement track of the conveying mechanism 3 through the conveying table 51.
